    Objective To investigate the anti-inflammatory and antioxidant effects of tanshinone capsule on imiquimod-induced psoriatic mouse model, so as to find a treatment for psoriasis. Methods The psoriatic mouse model was constructed with imiquimod cream. The effect of tanshinone capsule on the inflammatory response of psoriatic mouse model induced by imiquimod was evaluated by the PASI score and histopathology, the serum levels of interleukin (IL)-17A and tumor necrosis factor (TNF)-α were determined by enzyme-linked immunosorbent assay, and the expression levels of nuclear factor-E2-related factor 2 (Nrf2), antioxidant genes [heme oxygense-1 (HO-1) and superoxide dismutase 2 (SOD2)], and two-phase detoxification enzyme gene [NAD(P)H quinoneoxid oreductase 1 (NQO1)] were detected by the immunohistochemistry and real-time quantitative PCR. The statistical analysis method was one-way ANOVA. Results Tanshinone capsule improved the morphological features of imiquimod-induced psoriasis mice, including reduction of erythema, scales, and skin lesion thickness, thereby reducing the degree of inflammatory response. Tanshinone capsule could reduce the levels of IL-17A and TNF-α in serum of psoriatic mice (both P<0.05). Tanshinone capsule could also induce the increase of Nrf2, HO-1, and SOD2 in the skin tissue of psoriatic mice (all P<0.05). Conclusion Tanshinone capsule can reduce the IL-17A and TNF-α levels in serum of psoriasis-like mice and activate the Nrf2 signaling pathway, thus exerting the anti-inflammatory and antioxidant stress effects.

    Objective To explore and analyze the expression levels and significance of anterior pituitary hormones and thyroid hormones in patients with traumatic brain injury under different disease severity degrees. Methods A total of 103 patients with traumatic brain injury treated in Jincheng People's Hospital from May 2017 to May 2020 were selected as an observation group, including 58 males and 45 females, with an age of (43.12±4.11) years old, with 5 cases of skull fractures, 7 cases of cerebral concussion, 11 cases of cerebral contusion, 9 cases of epidural hematoma, and 8 cases of subdural hematoma, with the admission time after injury of (30.25±4.11) h. Serum levels of prolactin (PRL), follicle stimulating hormone (FSH), luteinizing hormone (LH), thyroid stimulating hormone (TSH), triiodothyronine (T3), and thyroxine (T4) were measured by enzyme-linked immunosorbent assay (ELISA) on day 1, 7, 14, and 30 after traumatic brain injury. A total of 100 normal people who came to Jincheng People's Hospital for routine physical examination during the same period were selected as the control group, including 55 males and 45 females, with an age of (43.20±4.34) years old, the same indicators mentioned above were measured, and the levels of anterior pituitary hormones and thyroid hormones were compared between the two groups. At the same time, the patients in the observation group were divided into a mild group (13-14 points), a moderate group (9-12 points), and a severe group (3-8 points) according to the Glasgow Coma Scale (GCS) score, and were divided into a death group, a disability group, and a good group according to the prognosis. The levels of anterior pituitary hormones and thyroid hormones in different GCS groups and different prognostic groups were compared. Independent sample t test was used for comparison of the measurement data between two groups, F test was used for comparison among multiple groups, and χ2 test was used for the count data. Results Compared with those in the control group, the levels of PRL, FSH, LH, TSH, and T4 in the observation group were higher on day 1 and 7 after craniocerebral injury, while the level of T3 was lower; the levels of PRL, FSH, LH, TSH, and T4 in the observation group decreased gradually and the level of T3 increased since day 7 after craniocerebral injury; the levels of PRL, FSH, LH, TSH, and T4 were still higher than those of the control group on day 14 after craniocerebral injury, while the level of T3 was lower, with statistically significant differences (all P<0.05). The severe group had higher levels of PRL, FSH, LH, TSH, and T4 and a lower level of T3 compared with the moderate group and the mild group, respectively; the moderate group had higher levels of PRL, FSH, LH, TSH, and T4 and a lower level of T3 compared with the mild group, with statistically significant differences (all P<0.05). The death group had higher levels of PRL, FSH, LH, TSH, and T4 and lower level of T3 compared with the disability group and the good group, respectively; the disability group had higher levels of PRL, FSH, LH, TSH, and T4 and lower level of T3 compared with the good group, with statistically significant differences (all P<0.05). Conclusion After traumatic brain injury, the levels of anterior pituitary hormones and thyroid hormones are significantly increased, and the changes of above indicators are helpful to judge the disease severity degree and prognosis in patients with traumatic brain injury, and provide reliable basis for clinical treatment.

    Objective To explore the correlation and difference of the lower neck and lower vertebral body of nasopharyngeal carcinoma in the same direction, to provide the basis for improving the accuracy of neck positioning, and to provide ideas for improving the head-neck-shoulder fixation device. Methods A total of 80 patients with nasopharyngeal carcinoma who received Varian Vital Beam linac radiation therapy were randomly selected in Sun Yat-sen University Cancer Prevention and Treatment Center from January to December 2021, and their 1 120 cone beam CT (CBCT) images were retrospectively analyzed. The correlations and differences of two different matching regions in the linear translation directions of left-right (LR), head-foot (SI), and anterior-posterior (AP) and in the axial rotation directions of transverse rotation Roll, sagittal rotation Pitch, coronal rotation RTN were analyzed. Pearson correlation analysis was used for the correlation analysis, Wilcoxon signed rank test or paired sample t test was used for the measurement data. Results In the linear translation directions of the lower neck and lower vertebral body, there was a moderate correlation in the LR direction (r=0.692, P<0.001), and there was no statistically significant difference (P>0.05); there was a moderate correlation in the SI direction (r=0.623, P<0.001), and there was a statistically significant difference (t=-2.967, P=0.003); there was a strong correlation in the AP direction (r=0.894, P<0.001), and there was a statistically significant difference (t=-5.965, P<0.001). In the axial rotation directions of the lower neck and lower vertebral body, there was a moderate correlation in the sagittal rotation Pitch direction (r=0.655, P<0.001), and there was a statistically significant difference (t=5.228, P<0.001); there was a moderate correlation in the coronal rotation RTN direction (r=0.594, P<0.001), and there was no statistically significant difference (P>0.05); there was a strong correlation in the transverse rotation Roll direction (r=0.758, P<0.001), and there was a statistically significant difference (Z=-2.985, P=0.003). Conclusions The correlation of the lower neck and the lower vertebral body is strong, so the lower vertebral body can be used as the reference to correct the lower neck error, but the difference caused by rotation error should be paid attention to. It is suggested to pay attention to correcting and guiding the patients' lying posture when positioning, and ensure that the position is consistent with the mask, to reduce the rotation error of the neck.

    Objective To investigate the effect of sacubitril/valsartan on chronic congestive heart failure in maintenance hemodialysis patients. Methods A total of 60 patients with New York Heart Association (NYHA) cardiac function classification Ⅲ-Ⅳ who underwent maintenance blood purification in Affiliated Central Hospital of Shenyang Medical College from January 2020 to January 2021 were selected and were divided into a study group and a control group according to the random number table method, with 30 cases in each group. The study group included 21 males and 9 females, aged (63.5±11.9) years; the control group included 15 males and 15 females, aged (61.9±11.3) years. Both groups were assessed by the same physician to achieve "dry weight". The study group was treated with sacubitril/valsartan on the basis of routine treatment, and the control group was treated with valsartan on the basis of routine treatment. Three months later, the changes of left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter (LVEDD), N-terminal pro-brain natriuretic peptide (NT-probNP), 6-min walking test distance (6MWT), serum creatinine (Scr), urea nitrogen (BUN), albumin, serum potassium, and blood pressure in the two groups before and after treatment were compared, and the cardiac function was assessed (all the above data were collected before dialysis). t test was used for the measurement data and χ2 test or Fisher's exact probability method was used for the count data. Results Before treatment, there were no statistically significant differences in the LVEF, LVEDD, NT-proBNP, 6MWT, Scr, BUN, albumin, serum potassium, and blood pressure between the two groups (all P>0.05). After treatment, the total effective rate of the study group was significantly higher than that of the control group [96.7% (29/30) vs. 73.3% (22/30)]; the LVEF, LVEDD, NT-proBNP, 6MWT, and blood pressure in both groups were better than those before treatment; compared with those in the control group, the LVEDD, NT-proBNP, and blood pressure in the study group were significantly reduced, while the LVEF and 6MWT were significantly increased; there were statistically significant differences between the two groups (all P<0.05). There were no significant changes in the Scr, BUN, albumin, and serum potassium between the two groups (all P>0.05). Conclusions Sacubitril/valsartan can effectively improve chronic congestive heart failure in maintenance hemodialysis patients, and significantly reduce the arterial blood pressure, at the same time, there is no significant increase in serum potassium, and no significant change in Scr, BUN, or albumin.

    Objective To investigate the effect of statins on the survival in maintenance hemodialysis (MHD) patients. Methods It was a retrospective study. A total of 186 patients with end-stage renal disease (ESRD) who received MHD treatment in the hemodialysis center of Xuzhou Medical University Affiliated Hospital of Lianyungang from June 2012 to June 2015 were selected as the research object, including 114 males and 72 females, aged 18-85 years. The patients treated with statins for 3 consecutive months before enrollment and during follow-up were taken as a statin group (48 cases), and the patients not treated with statins were taken as a non-statin group (138 cases). The patients' general data were collected, the patients were followed up until June 30, 2020, and the clinical outcomes were recorded. Independent sample t test was used for the measurement data, χ2 test or Fisher's exact probability method was used for the count data, Kaplan-Meier survival analysis was used for the survival, and COX regression model was used to analyze the influencing factors of survival and prognosis in MHD patients. Results Compared with the non-statin group, the statin group had higher systolic blood pressure (SBP) before dialysis, shorter dialysis years, lower weekly dose of erythropoietin, higher left ventricular ejection fraction (LVEF), a higher albumin (Alb) level, lower total cholesterol (TC) and triglyceride (TG) levels, and a lower C-reactive protein (CRP) level (all P<0.05); compared with the non-statin group, the statin group had lower mortality, a lower death rate due to cardiovascular diseases, and higher 3-year and 5-year survival rates (all P<0.05). Age, body mass index (BMI), SBP before dialysis, dialysis years, dialysis duration, cardiothoracic ratio, LVEF, hemoglobin (Hb), serum ferritin, Alb, parathyroid hormone (PTH), urea nitrogen (BUN), creatinine (Cr), TC, TG, CRP, and usage of phosphorus bond, calcium carbonate, lanthanum carbonate, sevelamer, sensipar, vitamin D, and statins were the influential factors for survival and prognosis in MHD patients (all P<0.05). Adjusting for the influences of other factors on the survival and prognosis in MHD patients, statins significantly reduced the risk of death in MHD patients (HR: 0.56, 95%CI: 0.51-0.59; P=0.017). Conclusion Statins have good anti-inflammatory, reduce the weekly dose of erythropoietin and the incidence of cardiovascular events, significantly improve the 3-year and 5-year survival rates in MHD patients, and reduce the risk of death, with clinical application values.

    Exosomes are vesicle-like substances actively secreted by cells, they can transport proteins, cytokines, microRNAs, and other substances to participate in the process of intercellular communication, thus play a role in regulating the function of corresponding receptor cells. When cells are stimulated, the number of exosomes and substances they transport will change correspondingly. Reperfusion therapy after acute myocardial infarction is usually achieved through thrombolytic therapy or percutaneous coronary intervention, and myocardial injury after reperfusion is a common phenomenon after vascular recanalization and also the main reason affecting prognosis. At present, there are no effective prevention and treatment measures for myocardial ischemia-reperfusion injury. Studies have shown that exosomes play an important role in regulating inflammatory response, angiogenesis, oxidative stress, ventricular remodeling, and myocardial cell apoptosis in myocardial ischemia-reperfusion injury, so they have great potential clinical application values.

    Objective To explore the difference in curative effects of cotton absorption combined with budesonide suspension in type Ⅰ tympanoplasty under dry and wet ear conditions. Methods A total of 66 patients with chronic suppurative otitis media at rest from Wuhan Xinzhou District People's Hospital and Huangshi Central Hospital from January 2018 to December 2020 were prospectively included. They were divided into four groups with the random number table method, including 17 cases in the dry ear observation group [11 males and 6 females, aged (36.23±7.39) years], 19 cases in the dry ear control group [12 males and 7 females, aged (37.28±7.29) years], 16 cases in the wet ear observation group [10 males and 6 females, aged (37.12±7.26) years], and 14 cases in the wet ear control group [9 males and 5 females, aged (37.75±7.17) years]. All patients underwent type Ⅰ tympanoplasty under otoendoscope, and the dry and wet ear observation groups were given cotton absorption combined with budesonide suspension to fix the tympanum and external auditory canal at the end of the operation. The preoperative eustachian function and levels of inflammatory factors [serum interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), and high-sensitivity C-reactive protein (hs-CRP)] and air-bone gaps before operation and 1 month and 3 months after operation in the four groups were counted and compared, and the dry ear rate, dry ear time, eardrum healing rate, and hearing improvement rate 6 months after operation were counted. t test or ANOVA was used for the measurement data, and Chi-square test or Fisher's exact probability method was used for the count data. Results There was no statistically significant difference in the preoperative eustachian function among the four groups before operation (P>0.05). The serum levels of IL-6, TNF-α, and hs-CRP in the four groups 1 month and 3 months after operation were higher than those before operation, and the air-bone gap was lower than that before operation; the serum levels of IL-6, TNF-α, and hs-CRP and air-bone gap 3 months after operation were lower than those 1 month after operation; 1 month and 3 months after operation, the serum levels of IL-6, TNF-α, and hs-CRP and air-bone gaps in the dry ear observation group and wet ear observation group were lower than those in the other two groups, with statistically significant differences (all P<0.05). Six months after operation, the dry ear rate was 16/17 (94.12%) in the dry ear observation group, 17/19 (89.47%) in the dry ear control group, 15/16 (93.75%) in the wet ear observation group, and 13/14 (92.86%) in the wet ear control group, without statistically significant difference among the four groups (P=1.000). The postoperative dry ear duration was (9.24±3.26) weeks in the dry ear observation group, (13.37±3.75) weeks in the dry ear control group, (9.11±3.17) weeks in the wet ear observation group, and (14.21±3.65) weeks in the wet ear control group; the postoperative dry ear durations in the dry ear observation group and wet ear observation group were shorter than those in the other two groups, with statistically significant differences (all P<0.05). Six months after operation, the healing rate of eardrum was 17/17 (100.00%) in the dry ear observation group, 18/19 (94.73%) in the dry ear control group, 15/16 (93.75%) in the wet ear observation group, and 14/14 (100.00%) in the wet ear control group, without statistically significant difference among the four groups (P=0.849). Six months after operation, the hearing improvement rate was 12/17 (70.59%) in the dry ear observation group, 7/19 (36.84%) in the dry ear control group, 13/16 (81.25%) in the wet ear observation group, and 6/14 (42.86%) in the wet ear control group; the hearing improvement rates in the dry ear observation group and the wet ear observation group were better than those in the other two groups, with a statistically significant difference (P<0.05). Conclusions For chronic suppurative otitis media at rest without ossicular chain lesions, there is no significant difference in the eardrum healing rate or dry ear rate of type Ⅰ tympanoplasty under otoendoscope under dry and wet ear conditions. The application of cotton absorption combined with budesonide suspension can speed up the improvement of inflammatory factors in the patients' body, shorten the dry ear time, and improve the degree of hearing improvement.

Methods The clinical data of 80 drug-resistant children with Hp infection treated in Children's Hospital Affiliated to Zhengzhou University from March 2019 to April 2021 were analyzed retrospectively. According to different nursing methods, they were divided into a control group [23 males, 17 females, with an age of (10.58±1.91) years old and a course of disease of (4.78±1.19) days] and an intervention group [21 males, 19 females, with an age of (10.68±2.31) years and a course of disease of (4.83±1.24) days], with 40 cases in each group. The control group was intervened by routine nursing mode, and the intervention group was intervened by cluster nursing mode. The medication compliance, treatment effect, scores of Screen for Child Anxiety Related Emotional Disorders (SCARED) and Quality of Life Scale for Children and Adolescents (QLSCA), and family satisfaction were compared between the two groups. Two independent sample t test was used for the measurement data, and χ2 test was used for the count data. Results The medication compliance and treatment effective rate in the intervention group were 87.5% (35/40) and 90.0% (36/40), respectively, which were higher than those in the control group [67.5% (27/40) and 72.5% (29/40)], with statistically significant differences (both P<0.05). After intervention, the SCARED score in the intervention group was lower than that in the control group [(19.50±1.72) vs. (21.48±2.01)], and the QLSCA score was higher than that in the control group [(61.08±3.29) vs. (58.50±4.33)], with statistically significant differences (both P<0.05). The satisfaction of the intervention group was higher than that of the control group, with a statistically significant difference (P<0.05). Conclusion The application of cluster nursing mode intervention in drug-resistant children with Hp infection can improve the medication compliance and quality of life.

    Objective To explore the normative application and effect of nursing information system in the management of patients and their families entering and leaving the ward. Methods From January 2020 to December 2021, 3 492 patients admitted to the department of medical oncology in Weihai Central Hospital were selected as the research subjects for a prospective study. Among them, 1 668 patients from January to December 2020 received routine management of patients and their families entering and leaving the ward, as a control group; 1 824 patients from January to December 2021 received management of patients and their families entering and leaving the ward based on the mobile nursing information system, as an observation group. The control group included 936 males and 732 females, aged (68.43±2.49) years; the observation group included 1 008 males and 816 females, aged (68.58±2.55) years. Before and after management of entering and leaving the ward based on the mobile nursing information system, the standard management rate of entering and leaving the ward, nursing work efficiency, daily visits, per capita time out of ward, patient satisfaction, and nurse job satisfaction were statistically analyzed. Independent sample t test was used for the measurement data and χ2 test was used for the count data. Results The standard management rate of one patient and one companion entering and leaving the ward in the observation group was 98.85% (3 606/3 648), which was higher than that in the control group [96.04% (3 204/3 336)], with a statistically significant difference (χ2=56.457, P<0.001). In the observation group, the time consuming of temperature monitoring, ultraviolet disinfection, and recording the time of patients and their families in and out of the ward were (24.25±1.17) s, (7.25±0.79) s, and (61.47±3.63) s, respectively, which were shorter than those in with control group [(50.36±10.24) s, (19.36±2.14) s, and (83.45±8.40) s], with statistically significant differences (t=108.130, 225.467, and 101.839; all P<0.001). The daily visits, per capita time out of ward in the observation group were (103.25±8.03) person/d and (30.21±3.20) min, respectively, which were lower than those in the control group [(140.24±11.26) person/d and (43.53±6.37) min], with statistically significant differences (t=159.056 and 111.809; both P<0.001). The patient satisfaction in the observation group was 98.03% (1 788/1 824), which was higher than that in the control group [94.60% (1 578/1 668)], with a statistically significant difference (χ2=29.334, P<0.001). The nurse job satisfaction in the observation group was (143.17±2.48) points, which was higher than that in the control group [(130.79±2.91) points], with a statistically significant difference (t=9.714, P<0.001). Conclusions The management of patients and their families entering and leaving the ward based on the mobile nursing information system can improve the efficiency of nursing work, and effectively improve the standard rate of ward management, reduce the daily number of people entering and leaving the ward, and shorten the per capita time out of ward. The satisfactions of both nurses and patients are improved, and the quality of nursing service is improved.

    Objective To explore the value of epidural anesthesia combined with general anesthesia in laparoscopic surgery for elderly patients with colorectal cancer. Methods A retrospective study was conducted on the clinical data of 133 elderly patients with colorectal cancer who underwent laparoscopic surgery in The First Affiliated Hospital of Nanyang Medical College from June 2020 to December 2021. After analyzing the medical records, the patients were divided into a control group (66 cases) and a study group (67 cases) according to different anesthesia schemes. There were 37 males and 30 females in the study group, aged (64.65±4.73) years; in the control group, there were 35 males and 31 females, aged (64.58±4.59) years. The control group received routine general anesthesia, and the study group received general anesthesia combined with epidural anesthesia. Nitric oxide (NO), Pittsburgh Sleep Quality Index (PSQI), adrenocortical hormone (ACTH), serum motilin (MTL), Mini Mental State Examination (MMSE), somatostatin (SS), D-lactic acid (D-LA), and the incidence of adverse reactions were compared between the two groups. t test was used for the measurement data, χ2 test was used for the count data, and rank sum test was used for the grade data. Results The levels of NO, ACTH, MTL, SS, and D-LA and scores of MMSE and PSQI in the two groups showed no significant differences 1 day before surgery (all P>0.05). Three days after surgery, the levels of NO and ACTH in the study group were (296.32±43.85) μmol/ml and (35.25±8.36) pg/ml, respectively, which were lower than those in the control group [(353.57±58.36) μmol/ml and (43.54±7.69) pg/ml], with statistically significant differences (both P<0.05). Seven days after surgery, the level of D-LA of the study group was (115.75±21.13) μg/L, which was lower than that of the control group [(138.75±19.26) μg/L], the levels of MTL and SS were (237.91±51.06) pg/ml and (556.17±23.26) pg/ml, respectively, which were higher than those in the control group [(215.45±40.95) pg/ml and (544.28±20.14) pg/ml], with statistically significant differences (all P<0.05). Three days after surgery, the MMSE score of the study group was (25.43±2.41), which was higher than that of the control group [(21.69±3.23)], and the PSQI score was (5.59±1.15), which was lower than that of the control group [(7.46±1.62)], with statistically significant differences (both P<0.05). The incidence of adverse reactions in the study group was 2.98% (2/67), which was significantly lower than that in the control group [15.15% (10/66)] (χ2=5.995, P=0.014). Conclusion Epidural anesthesia combined with general anesthesia is effective in laparoscopic surgery for elderly patients with colorectal cancer, which is helpful to reduce their surgical stress response and promote the recovery of gastrointestinal and cognitive functions after surgery.

    Objective To compare the effects of intermittent peritoneal dialysis (IPD) and continuous veno-venous hemodialysis (CVVHD) on the removal of inflammatory factors in the early stage of severe pancreatitis, and analyze the role of IPD in early treatment for severe pancreatitis. Methods A total of 24 patients with severe pancreatitis who received treatment in Dongguan Tungwah Hospital from October 2015 to October 2020 were selected as the research objects, including 12 patients with severe pancreatitis who received CVVHD from October 2015 to August 2018 as a control group and 12 patients with severe pancreatitis who received IPD from September 2018 to October 2020 as an observation group. The observation group included 8 males and 4 females, aged (42.19±11.59) years; the control group included 7 males and 5 females, aged (44.30±8.80) years. The control group was treated with medical conservative treatment combined with CVVHD, and the observation group was treated with medical conservative treatment combined with IPD. The basic data, inflammatory factors, and laboratory indicators in the two groups were collected, and the relevant indicators were analyzed. Independent sample t test and Fisher exact probability method were used. Results There were no statistically significant differences in the length of ICU stay, duration of mechanical ventilation, and incidence of complications between the two groups (all P>0.05). There were statistically significant differences in the concentrations of interleukin-6 (IL-6) and IL-10 between the two groups on day 3 and day 7 [(105.43±39.41) U/ml vs. (170.00±38.53) U/ml, (62.00±14.74) U/ml vs. (110.43±23.29) U/ml, (5.56±3.00) U/ml vs. (11.69±3.71) U/ml, (4.50±2.12) U/ml vs. (12.27±5.89) U/ml] (t=4.058, 6.087, 4.451, and 4.299; all P<0.001). There was a statistically significant difference in the concentration of tumor necrosis factor -α (TNF-α) between the two groups only on day 3 [(12.72±3.82) μg/L vs. (8.18±2.98) μg/L] (t=3.246, P=0.004). There were statistically significant differences in the C-reactive protein (CRP) concentration between the two groups on day 1 and day 7 [(53.75±11.47) mg/L vs. (111.72±60.34) mg/L, (75.75±18.98) mg/L vs. (123.58±47.57) mg/L] (t=3.269, 3.235; P=0.003, 0.004). Conclusion IPD is an effective method in early treatment for severe pancreatitis.

    Objective To investigate the correlations between diopter and retinal thickness and macular blood flow in adolescent myopia patients. Methods Fifty-eight adolescent myopia patients admitted to the outpatient department of Dongguan Guangming Eye Hospital from May 2020 to December 2021 were retrospectively analyzed, including 19 cases of low myopia, 21 cases of medium myopia, and 18 cases of high myopia, and 22 adolescents with normal vision were selected as the control group. In the low myopia group, there were 10 males and 9 females, aged (12.38±3.03) years; in the medium myopia group, there were 11 males and 10 females, aged (13.01±2.95) years; in the high myopia group, there were 9 males and 9 females, aged (12.85±3.11) years; in the control group, there were 11 males and 11 females, aged (13.08±3.32) years. The indexes related to macular blood flow and retinal thickness were measured by Cirrus HD-OCT-5000 instrument from Zeiss, Germany. The peripheral, upper, lower, nasal, and temporal retinal thicknesses were compared between the myopia group and the control group; the peripheral, upper, lower, nasal, and temporal retinal thicknesses were compared among the low, medium, and high myopia groups; the indexes related to macular blood flow in the low, medium, and high myopia groups were compared. Pearson correlation analysis was used to analyze the correlations between patients' diopter and retinal thickness and macular blood flow indexes. Independent sample t test or F test was used for the measurement data, and χ2 test was used for the count data. Results The peripheral, upper, lower, nasal, and temporal retinal thicknesses in the myopia group were (93.68±10.25) μm, (118.63±9.87) μm, (110.33±10.37) μm, (57.93±8.14) μm, and (87.91±8.33) μm, respectively, which were significantly lower than those in the control group [(105.43±8.52) μm, (134.77±9.65) μm, (133.26±8.08) μm, (79.43±9.66) μm, and (102.44±6.78) μm], with statistically significant differences (all P<0.05). In the low, medium, and high myopia groups, the peripheral, upper, lower, nasal, and temporal retinal thicknesses decreased successively, with statistically significant differences (all P<0.05). There were no statistically significant differences in the vascular density in zone 1 (VD1), perfusion density in zone 1 (PD1), and perfusion density in zone 4 (PD4) among the low, medium, and high myopia groups (all P>0.05); the vascular density in zone 4 (VD4) and foveal avascular zone (FAZ) showed statistically significant differences among the three groups (all P<0.05), and the VD4 and FAZ decreased with the increase of myopia. Pearson correlation analysis showed that diopter was negatively correlated with retinal thickness and FAZ (r=-0.648, P<0.001; r=-0.312, P=0.003), and was not significantly correlated with VD4 (P>0.05). Conclusion The more severe myopia in adolescent myopia patients, the smaller the retinal thickness, and the lower the FAZ, showing a negative correlation, but the causal relationship needs to be studied in a multi-center.

    Objective To investigate the current situation of myopia and its influencing factors among primary and secondary school students in Emin, Xinjiang. Methods It was a cross-sectional study. A total of 2,611 primary and secondary school students, including 1,265 males and 1,346 females, were randomly selected from three schools in Emin, Xinjiang, including Xiaobaiyang Primary School, Xiaobaiyang Junior Middle School, and Longzhen Senior Middle School, from September 18, 2019 to September 25, 2019. The axial length (AL) and corneal curvature (CR) were measured with the IOL-Master500. The sub-pupillary equivalent sphericity (SE) was examined with the Solvay SW-800 vision screener; according to the SE measured, the students were divided into a low myopia group (-0.50 D ≤SE ≤-3.00 D), a moderate myopia group (-6.00 D <SE <-3.00 D), a high myopia group (SE ≤-6.00 D), a emmetropia group (naked visual acuity ≥0.8, absolute value of SE <0.50 D), a low hyperopia group (0.50 D - +3.00 D), a moderate hyperopia group (+3.25 D - +5.00 D), and a high hyperopia group (≥5.25 D). The differences of diopter and ocular biological parameters among different age and dioptric groups were compared by one-way ANOVA, the comparison of ocular biological parameters between two groups was performed by independent sample t test, and the correlation analysis was performed by Pearson and Spearman correlation analysis. Results The prevalence of myopia among 2 611 students was 59.3% (1 548/2 611), the prevalence of low myopia, moderate myopia, and high myopia were 41.7% (1 090/2 611), 15.6% (408/2 611), and 2.0% (50/2 611), and the prevalence of myopia increased with age (P<0.01). The correlation analysis of ocular biological parameters among different age groups showed that the SE was correlated with AL/CR and LogMRA visual acuity; there were statistically significant differences in the AL, SE, AL/CR, and LogMAR visual acuity among different age groups in the comparison from 8 to 18 years old (all P<0.01). There were statistically significant differences in the AL, SE, CR, AL/CR, and LogMRA visual acuity in the comparison of ocular biological parameters among different dioptric groups (all P<0.01), and the AL and AL/CR in the high myopia group were higher than those in other groups. Correlation analysis showed that the linear regression equations of AL, AL/CR and SE were as follows: SE = 24.76-1.09 AL (P<0.01, r=-0.73, R2=51.43), SE = 29.25-10.06 AL/CR (P<0.01, r=-0.83, R2=73.08). Conclusions The prevalence of myopia is high among primary and middle school students in Emin County, Xinjiang. There are differences in the ocular biological characteristics among primary and secondary school students of different ages, the SE is correlated with AL and AL/CR, among which the AL/CR has a great influence on the change of refraction, which is of guiding significance for monitoring the occurrence and development of myopia.

    Objective To understand and master the incidence of myopia among primary school students in urban areas of Guilin city and analyze its related influencing factors, so as to provide data support for relevant departments to formulate the prevention and control strategies of myopia among primary school students in the region. Methods In May 2021, 3 578 students were selected from 3 primary schools in urban areas of Guilin city by the cluster sampling method, including 1 837 males and 1 741 females, aged (9.91±1.66) years,and a questionnaire survey, ophthalmic visual examination, and optometric examination were conducted. The collected data were statistically analyzed by SPSS 22.0 software. The count data were tested by χ2 test. Results The prevalence of myopia among urban primary school students in Guilin was 38.23% (1 368/3 578), which increased with the increase of grade (χ2=54.120, P=0.003). The more time spent watching TV after school, the higher the incidence of myopia was (χ2=15.340, P=0.002). The results of multi-factor non-conditional logistic regression analysis showed that study time >8 h per day, no rest after reading for 40 min, distance from electronic products <30 cm, time of outdoor exercise <2 h per day were the high risk factors for myopia (all P<0.05). Conclusion According to the factors affecting the occurrence of myopia in primary school students, targeted intervention measures are researched and formulated, and parents and schools should urge children's eye habit to develop healthy eye habit and minimize the occurrence of myopia.

    Objective To explore the value of 256-slice spectral CT imaging parameters in the diagnosis and treatment guidance of lung adenocarcinoma. Methods A total of 120 patients with lung adenocarcinoma and 83 patients with lung squamous cell carcinoma who were admitted to Hubei Third People's Hospital Affiliated to Jianghan University from May 2018 to January 2022 were selected as the research subjects. All patients underwent 256-slice spectral CT imaging, and the spectral CT imaging parameters were compared between the two groups. The value of spectral CT imaging parameters in the diagnosis of lung adenocarcinoma and lung squamous cell carcinoma was analyzed. The patients with lung adenocarcinoma were grouped according to the curative effect of targeted therapy, and the spectral CT imaging parameters before and after treatment were compared between the effective group and the ineffective group. The relationship between spectral CT imaging parameters and curative effect was analyzed. t test, χ2 test, receiver operating characteristic curve (ROC), and Spearman correlation analysis were used. Results There were 76 males and 44 females in the lung adenocarcinoma group, with an age of (45.26±2.95) years old; there were 58 males and 25 females in the lung squamous cell carcinoma group, with an age of (45.11±2.07) years old. The calcium content, effective atomic number, iodine concentration, and slope of energy spectrum curve in the lung adenocarcinoma group were (3.16±0.86) mg/ml, (7.79±0.05), (6.76±0.96) g/L, and (0.94±0.24), respectively, which were lower than those in the lung squamous cell carcinoma group [(4.71±1.09) mg/ml, (7.84±0.06), (7.92±1.13) g/L, and (1.24±0.32)], with statistically significant differences (all P<0.05); there was no statistically significant difference in the water base value between the lung adenocarcinoma group and the lung squamous cell carcinoma group (P>0.05). The areas under the curve (AUC) of the above parameters to diagnose lung adenocarcinoma and lung squamous cell carcinoma were 0.832, 0.754, 0.792, and 0.722, respectively, and the AUC of combined diagnosis with these parameters was 0.932. After treatment, the calcium content, effective atomic number, iodine concentration, and slope of energy spectrum curve were significantly reduced in both groups (all P<0.05). The calcium content, effective atomic number, iodine concentration, and slope of energy spectrum curve in the effective group were lower than those in the ineffective group before and after treatment (all P<0.05); the difference values of these parameters before and after treatment in the effective group were higher than those in the ineffective group (all P<0.05). Spearman correlation analysis showed that calcium content, effective atomic number, iodine concentration, and slope of energy spectrum curve were negatively correlated with curative effect (r=-0.413, -0.628, -0.527, and -0.385; all P<0.05). Conclusion 256-slice spectral CT imaging parameters are helpful in the diagnosis of lung adenocarcinoma, which can reflect the curative effect, and provide references for condition and curative effect evaluation.

    Objective To analyze the risk factors of intracranial hemorrhage in premature infants with gestational age less than 34 weeks. Methods The clinical data of 187 premature infants with gestational age less than 34 weeks who were hospitalized in neonatal intensive care unit (NICU) of Guangzhou First People's Hospital from January 2016 to December 2021 were selected for analysis. Fifty-three premature infants with gestational age <34 weeks whose imaging findings indicated intracranial hemorrhage were selected as a intracranial hemorrhage group, and 134 premature infants with gestational age <34 weeks whose imaging findings did not indicate intracranial hemorrhage were selected as a control group. The clinical data of the two groups were collected for a retrospective study. Univariate analysis [independent sample t test, χ2 test, and Fisher's exact probability method] and multivariate logistic regression analysis were used to analyze the risk factors for intracranial hemorrhage in premature infants. Results In the intracranial hemorrhage group, there were 26 males and 27 females, with a gestational age of (30.22±2.31) weeks; in the control group, there were 70 males and 64 females, with a gestational age of (32.04±1.49) weeks. Univariate analysis showed that there were no statistically significant differences in the rates of cesarean section, mother ≥35 years old, test tube baby, twins, amniotic fluid contamination, gestational diabetes, gestational hypertension, placental abruption, premature rupture of membrane, and placenta previa between the two groups (all P>0.05); the rates of gestational age <30 weeks, body weight <1.5 kg, prenatal chorioamnionitis, intrauterine distress, intrauterine infection, Apgar score ≤7 at birth, neonatal respiratory distress syndrome, patent ductus arteriosus, mechanical ventilation, pulmonary hemorrhage, and platelet count (PLT) <150×109/L in the intracranial hemorrhage group were 43.40% (23/53), 58.49% (31/53), 50.94% (27/53), 43.40% (23/53), 28.30% (15/53), 47.17% (25/53), 83.02% (44/53), 52.83% (28/53), 84.91% (45/53), 11.32% (6/53), and 16.98% (9/53), which were higher than those in the control group [10.45% (14/134), 30.60% (41/134), 34.33% (46/134), 8.21% (11/134), 12.69% (17/134), 20.15% (27/134), 58.21% (78/134), 26.12% (35/134), 55.22% (74/134), 1.49% (2/134), and 0.75% (1/134)], with statistically significant differences (all P<0.05); the prenatal usage rates of magnesium sulfate and dexamethasone in the intracranial hemorrhage group were 60.38% (32/53) and 49.06% (26/53), respectively, which were lower than 85.82% (115/134) and 71.64% (96/134) in the control group, with statistically significant differences (both P<0.05). Multivariate logistic regression analysis showed that gestational age <30 weeks, intrauterine infection, intrauterine distress, and PLT <150×109/L were independent risk factors for intracranial hemorrhage in premature infants, while prenatal usage of magnesium sulfate was an independent protective factor for intracranial hemorrhage in premature infants (all P<0.05). Conclusion To reduce the incidence of intracranial hemorrhage in premature infants, comprehensive evaluation, early detection, early diagnosis, and early treatment should be conducted in clinical work.

    Objective To explore the language expression and language comprehension abilities in children with language barrier, and to provide important references for the diagnosis and differential diagnosis. Methods From May 2020 to March 2022, 60 children with expressive language barrier and 60 children with receptive language barrier who were diagnosed in Department of Child Health, Affiliated Hospital of Qingdao University were selected as the experimental group, and 70 children with global developmental delay who were treated in the outpatient clinic during the same period were selected as the disease control group, and 64 normal children who underwent the developmental screening of outpatient physical examination during the same period were selected as the normal control group. In the expressive language barrier group, there were 38 males and 22 females, aged (29.13±4.99) months; in the receptive language barrier group, there were 36 males and 24 females, aged (31.67±9.33) months; in the disease control group, there were 45 males and 25 females, aged (29.44±7.95) months; in the normal control group, there were 43 males and 21 females, aged (30.05±6.64) months. The language comprehension and expression abilities were evaluated by the Infant-Toddler Language Development Scale, and the neuropsychological development was assessed by the Neuropsychological Development Scale for Children 0-6 Year-Old. Statistical analysis was performed by one-way ANOVA, SNK-q test, and χ2 test. Results In the expressive language barrier group, the expressive language age was (15.962±7.410) months, the comprehensible language age was (22.863±6.235) months, the expressive language score was (52.885±19.216) points, and the comprehensible language score was (78.205±17.100) points; those in the receptive language barrier group were (16.183±7.253) months, (18.770±7.652) months, (49.050±14.038) points, and (58.043±12.050) points; there were statistically significant differences compared with those in the normal control group [(35.939±11.127) months, (35.908±11.211) months, (117.804±22.277) points, and (117.857±22.498) points] and the disease control group [(11.461±5.360) months, (12.506±3.321) months, (37.640±10.732) points, and (44.353±14.106) points] (all P<0.05). There were statistically significant differences in the comprehensible language age and comprehensible language score between the expressive language barrier group and the receptive language barrier group (all P<0.05). In the expressive language barrier, the actual age difference of expressing, actual age difference of understanding, and actual age difference of understanding-then-expressing were (-13.172±4.225) months, (-6.270±4.337) months, and (-5.622±5.274) months, there were statistically significant differences compared with those in the normal control group [(5.877±6.820) months, (5.839±6.865) months, and (-0.188±1.053) months], the disease control group [(-17.231±5.534) months, (-16.866±7.317) months, and (-3.574±3.036) months], and the receptive language barrier group [(-15.483±4.318) months, (-12.897±4.048) months, and (-3.580±1.872) months] (all P<0.05). There were statistically significant differences in the above aspects between the normal control group and the receptive language barrier group (all P<0.05). There was a statistically significant difference in the actual age difference of understanding between the disease control group and the receptive language barrier group (P<0.05). Conclusions The language comprehension and expression abilities in children with expressive language barrier and receptive language barrier are lagging behind those in the normal control group. The actual age difference of expressing, actual age difference of understanding, and actual age difference of understanding- then-expressing have important references for distinguishing the types of language barrier.

    Objective To analyze the application of airway management based on ESEIA theory (eliminate – simplify – establish – integrate - automate) in mechanical ventilation for patients with severe craniocerebral injury combined with acute respiratory distress syndrome (ARDS). Methods It was a prospective study. A total of 70 patients with severe craniocerebral injury combined with ARDS treated by mechanical ventilation in Jinan Central Hospital from October 2019 to October 2021 were selected, and were divided into a control group and an observation group by the random number table method. In the control group, there were 19 males and 16 females, aged (45.28±2.41) years; in the observation group, there were 21 males and 14 females, aged (45.11±2.23) years. The control group was given routine airway management, and the observation group was given ESEIA theory-based flow-optimized airway management on the basis of the control group. The incidence of respiratory complications, blood gas analysis indexes, positive rate of sputum culture, 5-day sputum suction times, mechanical ventilation comfort, and nursing satisfaction were compared between the two groups. Independent sample t test and χ2 test were used. Results The incidence of respiratory complications and positive rate of sputum culture in the observation group were lower than those in the control group [5.71% (2/35) vs. 22.86% (8/35), 2.86% (1/35) vs. 20.00% (7/35)], with statistically significant differences (χ2=4.200 and 5.081; P=0.040 and 0.024). After intervention, the blood oxygen saturation (SaO2), arterial partial pressure of oxygen (PaO2), and 5-day sputum suction times in the observation group were all better than those in the control group [(95.79±1.42)% vs. (89.57±2.01)%, (87.32±1.01) mmHg vs. (83.25±2.74) mmHg(1 mmHg=0.133 kPa), (30.25±4.37) times vs. (38.11±6.28) times], with statistically significant differences (t=14.952, 8.245, and 6.078; all P<0.001). After intervention, the physical, psychological, social and cultural, and comfort scores in the observation group were better than those in the control group [(18.55±1.11) points vs. (15.65±1.52) points, (34.22±1.65) points vs. (29.92±2.33) points, (21.48±1.39) points vs. (16.77±1.26) points, (25.44±2.41) points vs. (21.37±2.05) points], with statistically significant differences (t=9.115, 8.910, 14.853, and 7.610; all P<0.001). The nursing satisfaction of the observation group was higher than that of the control group [97.14% (34/35) vs. 82.86% (29/35)], with a statistically significant difference (χ2=3.968, P=0.046). Conclusion Airway management based on ESEIA theory can effectively reduce the incidence of respiratory complications in patients with severe craniocerebral injury combined with ARDS treated by mechanical ventilation, and improve their blood gas indicators, prognosis, comfort during mechanical ventilation, and nursing satisfaction.

    Objective To analyze the effect of targeted nursing in the prevention of vaginal adhesion and stricture in patients with cervical cancer undergoing concurrent chemoradiotherapy. Methods A total of 106 patients with cervical cancer treated in Tianjin Cancer Hospital Airport Hospital from June 2019 to March 2020 were prospectively selected as the examples. They were divided into a control group (53 cases) and an observation group (53 cases) by the random number table method. The control group was (46.53±2.51) years old and the course of disease was (19.62±1.63) months; the observation group was (46.83±2.56) years old and the course of disease was (19.35±1.52) months. The control group received routine nursing; on this basis, the observation group received targeted nursing. Negative emotions [Hamilton Anxiety Scale (HAMA) and Hamilton Depression Scale (HAMD)] 1 day before intervention and 2 weeks after intervention, recurrence, vaginal adhesion and stenosis, and patients' nursing satisfaction were compared between the two groups. t test and χ2 test were used. Results After 2 weeks of intervention, the HAMA and HAMD scores in the observation group were lower than those in the control group [(8.95±2.07) points vs. (12.67±2.38) points, (9.64±1.27) points vs. (12.65±1.35) points], with statistically significant differences between the two groups (t=8.586 and 11.823; both P<0.001). The recurrence rate of the observation group was lower than that of the control group [3.77% (2/53) vs. 24.53% (13/53)], the vaginal adhesion rate was lower than that of the control group [3.77% (2/53) vs. 18.87% (10/53)], the stenosis rate was lower than that of the control group [1.89% (1/53) vs. 15.09% (8/53)], and the total nursing satisfaction was higher than that of the control group [96.23% (51/53) vs. 81.13% (43/53)], with statistically significant differences between the two groups (χ2=9.396, 6.014, 5.950, and 6.014; P=0.002, 0.014, 0.015, and 0.014). Conclusion Targeted nursing intervention has a good effect for patients with cervical cancer, which can significantly stabilize their mood and reduce the incidence of vaginal adhesion.

    Objective To analyze the application value of cluster nursing with tabular management on patients after diabetic retinopathy (DR) surgery. Methods The clinical data of 89 patients with DR treated in Jinan Second People's Hospital between March 2019 and June 2021 were retrospectively analyzed, and they were divided into a control group (44 cases, 59 affected eyes) and an observation group (45 cases, 65 affected eyes) depending on different intervention methods. The control group included 21 males and 23 females, aged (42.18±10.27) years; the observation group included 23 males and 22 females, aged (42.39±10.52) years. The control group was given routine nursing after DR surgery, and the observation group was given cluster nursing intervention with tabular management on the basis of the control group. Both groups were intervened for 1 month. The self-care ability and quality of life were assessed by Exercise of Self-Care Agency Scale (ESCA) and Scale of Life Quality for Diseases with Visual Impairment (SQOL-DVI) before and after intervention, Brief Illness Perception Questionnaire (BIPQ) was used to assess the disease cognition of the two groups, and the incidence of postoperative complications (corneal edema, retinal detachment, and vitreous hemorrhage) was compared between the two groups. t test was used for the measurement data, χ2 test was used for the count data, and Mann-Whitney U test was used for the grade data. Results After intervention, the total score of ESCA in the observation group was higher than that in the control group [(110.19±13.59) points vs. (96.59±12.47) points], with a statistically significant difference (t=4.916, P<0.001). The improvement of BIPQ grading in the observation group was better than that in the control group (U=2.520, P=0.012). The incidence of complications in the observation group was lower than that in the control group [4.44% (2/45) vs. 18.18% (8/44)], with a statistically significant difference (χ2=4.210, P=0.040). After intervention, the total score of SQOL-DVI in the observation group was higher than that in the control group [(87.59±12.64) points vs. (75.52±11.77) points], with a statistically significant difference (t=4.660, P<0.001). Conclusion Cluster nursing with tabular management can improve the disease self-care ability and disease cognition level in patients after DR surgery, reduce the incidence of complications, and improve their quality of life.

    Objective To investigate the effect of warfarin pathway table combined with feedback on the levels of anticoagulation cognition and self-management in patients after mechanical heart valve replacement. Methods A total of 120 patients who underwent mechanical heart valve replacement in Cardiovascular Surgery, The First Affiliated Hospital of Henan University of Science and Technology from January 2020 to October 2021 were divided into two groups according to the order of admission. Due to the influence of critical conditions, loss of contact, and other factors, 55 cases in the control group and 57 cases in the observation group completed the study. The control group included 25 males and 30 females, aged (55.37±8.67) years; the observation group included 26 males and 31 females, aged (54.21±7.73) years. The control group was given health education guidance by feedback method, and the observation group was intervened by warfarin pathway table combined with feedback method. The two groups were tested for anticoagulation cognition level 4 h before discharge and self-management level 1 month after discharge and the results were statistically analyzed. Independent sample t test, χ2 test, Fisher's exact probability test, and rank sum test were used. Results The good rate of anticoagulation cognition level 4 h before discharge in the observation group was higher than that in the control group [78.9% (45/57) vs. 61.8% (34/55)], and the good rate of self-management level 1 month after discharge was higher than that in the control group [75.4% (43/57) vs. 54.5% (30/55)], with statistically significant differences between the two groups (both P<0.05). The total excellent and good rates of anticoagulation cognition level and self-management level were higher in both groups, but there were no statistically significant differences between the two groups (both P>0.05). Conclusion Applying warfarin pathway table combined with feedback method to carry out systematic health education for patients after mechanical heart valve replacement can make full use of the superposition effect of efficient nursing, significantly increase their anticoagulation cognition level and self-management level, and improve their postoperative quality of life, which has a certain clinical value.

    Aging is the primary risk factor of cardiovascular diseases such as coronary artery disease, heart failure, and myocardial infarction. The poor prognosis of these diseases is caused by the decline of immunity and long recovery period. At the same time, cardiovascular diseases have been the leading cause of death in 40% of individuals over 65 years old. Senescent cells can accelerate the progression of cardiovascular diseases by expressing pro-inflammatory and pro-fibrotic secreted proteins. It has been shown that some targeted drugs can induce the apoptosis of senescent cells, and these bioactive compounds that preferentially remove senescent cells are known as Senolytics. This paper focuses on the research progress of Senolytics in coronary heart disease, heart failure, myocardial infarction, and so on.

    Seborrheic keratosis (SK) is a common benign epidermal tumor that occurs in adults, with almost no malignant transformation. However, it is easy to be confused with other skin tumors, and surgical resection and histopathological examination are required when the diagnosis is not clear. People often seek medical removal of skin lesions for cosmetic purposes. Drugs, ultrasound, laser, photodynamic therapy (PDT), nanosecond electric field, hyperbaric oxygen, and acupuncture are also effective besides surgical excision. This article summarizes the recent non-surgical treatments for SK.

    Coronary microvascular disease is a high-risk factor for a variety of cardiovascular events. Because of its complex etiology and hidden nature, its pathogenesis is still limited at this stage. In the occurrence and development of coronary microvascular endothelial cell (CMEC) dysfunction, CMEC damage is the main core link leading to its occurrence. The metabolic capacity, stress capacity, inflammation, and other related functions of CMEC are closely related to CMEC dysfunction, and it is also the main clinical feature in the early stage of its occurrence. Since the related pathological mechanism of CMEC injury has not been fully clarified at this stage, based on this, this study summarizes the related pathological mechanism of CMEC dysfunction, in order to provide a better understanding on the complex pathological mechanism of the disease for clinical medical staff, so as to provide a certain reference for the progress of subsequent related researches.
