Objective To observe the morphology changes in articular cartilage of knee osteoarthritis ( KOA) model rats after intervention with Shudi Jisheng Zhuanggu Decoction (SJZD). Methods SD rats were randomized into 7 groups, namely blank control group, model group, Paracetamol group ( 0.270 g/kg) , Zhuangu Guanjie Pills group ( 1.08 g/kg) , and high-, middle- and low-dosage SJZD groups ( 27.450, 13.725, 6.863 g/kg, respectively). Rats were injected with papain solution into the right knee joint to build models of KOA before administration of drugs. Thickness of right knee joint was measured to evaluate the effect of SJZD on the swelling degree of knee joint. Histological changes of knee cartilage were evaluated by Mankin scoring method after the cartilage sections being stained with hematoxylin-eosin (HE). Results Swelling degree of knee joint and Mankin scores were significantly increased in the model group compared to the blank control group ( P<0.01). In comparison with the model group, the swelling degree of knee joint and Mankin scores of SJZD groups were significantly decreased (P<0.05 or P<0.01), and the pathological changes were relieved. Conclusion SJZD can ameliorate the pathological changes of knee articular cartilage in rats with KOA, so as to delay cartilage degeneration and protect the cartilage.

Objective:To investigate the impact of China's Mental Health Law on the work of psychological counseling in colleges and universities, and to explore ways to improve the law. Methods: Totally 12 heads of college and university counseling centers in Beijing were conducted with semi-structured interviews. The average age of the interviewees was (40 ±7) years old, with master or doctor degrees in psychology or related disciplines. The method of content analysis was used to analyze the interviewees' understanding of the " Mental Health Law". Results: All of the 12 interviewees had gained some understanding of the "Mental Health Law", and accordingly amended the regulation of their counseling centers. Also, interviewees suggested the positive and negative impacts brought by the law, such as enhancing practitioners' legislative sense, clarifying their responsibilities and boundaries as college and university counseling, as well as difficulties to distinguish psychotherapy and psychological counseling, ambiguity in the legality of working with students who were diagnosed with mental disorders. Moreover, interviewees threw out suggestions on improving the law from the aspect of industry standard, supervision department and vocational qualification. Conclusion: The execution of "Mental Health Law" improves practitioners' legislative sense, clarifies their responsibility. Nevertheless, it does not clearly distinguish psychotherapy from psychological counseling, and be lack of regulation on the psychological counseling industry.

Objective:To investigate the correlation between gender, age, blood collection time, season and changes in cTnT concentration.Methods:In this study, 3548 patients (non-cardiovascular diseases) in Zhongshan Hospital of Fudan University were selected from 1 January to 31 December 2019. The basic data of the patients were collected, including gender, age, time of blood collection, medical history, clinical diagnosis, and results of cTnT testing. 1 840 males and 1 708 females were finally enrolled, with an age distribution of 65 (53, 75) years. The distribution of the data was assessed using the Kolmogorov-Smirnov (K-S) test, where non-normally distributed data were expressed as M( Q1, Q3). The Mann-Whitney U-test was used to compare cTnT concentrations between men and women, and to analyse the influence of gender on cTnT results. The Kruskal-Wallis test was used to compare cTnT levels between gender groups, to analyse the correlation between different times of blood collection, seasons, and other factors and cTnT concentrations. Result:cTnT concentrations increased with age in both males and females over the age of 60 years. cTnT levels were highest in individuals over the age of 90 years (0.028 ng/ml in males and 0.018 ng/ml in females). cTnT levels were higher in males (0.012 ng/ml) than in females (0.009 ng/ml) in all age groups ( H=6.340, P<0.01). The concentrations of cTnT varied at different time points of blood collection. In both males and females, cTnT concentrations reached a maximum at 8:00 and 13:00 (0.013 ng/ml and 0.012 ng/ml, respectively). Analysis of the physiological effect of season on cTnT secretion showed that cTnT levels were generally higher in spring and winter(0.012 ng/ml) than in summer and autumn(0.010 ng/ml). Conclusions:cTnT concentration is influenced by gender, age, time of blood collection and season. When analysing cTnT results in clinical practice, the gender and age of the individual should be taken into account, as well as the time point of blood collection and seasonal factors.

OBJECTIVETo study the relationship between carbon dioxide combining power(CO₂-CP) and contrast-induced acute kidney injury (CI-AKI) in patients with ST segment elevation myocardial infarction and undergoing percutaneous coronary intervention.

METHODSWe retrospectively analyzed 174 patients admitted to our hospital from March 2012 to August 2013 with ST segment elevation myocardial infarction and underwent emergency percutaneous coronary intervention. Patients were divided into three tertiles according to pre-operative CO₂-CP: T1 (CO₂-CP < 22.62 mmol/L), T2(CO₂-CP 22.62-24.30 mmol/L), T3(CO₂-CP > 24.30 mmol/L). Baseline clinical data, CI-AKI incidence, in-hospital mortality and dialysis rate were compared among groups. An increase in serum creatinine of >26.4 µmol/L and/or >50% from baseline within 48 hours after contrast exposure was defined as CI-AKI. Univariate logistic regression analysis was used to identify the risk factors of CI-AKI. The relationship between CO₂-CP and CI-AKI was assessed by multivariate logistic regression analysis. Receiver operating characteristic curve was used to identify the optimal cutoff of the CO₂-CP for predicting CI-AKI.

RESULTSCI-AKI occurred in 25 (14.4%) patients, and lower CO₂-CP was related to higher incidence of CI-AKI (27.6% (16/58) in group T1, 5.3% (3/57) in group T2, 1.7 % (1/59) in group T3, P = 0.002) and higher in-hospital mortality (10.3% (6/58) vs. 0 and 1.7% (1/59), P = 0.010). Dialysis rate was similar among 3 groups (5.2% (3/58) vs. 0 and 1.7% (1/59), P = 0.168). The incidence of CI-AKI was significantly associated with CO₂-CP < 22.00 mmol/L in univariate analyses (OR = 6.767, 95% CI 2.731-16.768, P < 0.001). After adjusting for potential confounding risk factors, CO₂-CP < 22.00 mmol/L remained significantly associated with the incidence of CI-AKI (OR = 5.835, 95%CI 1.800-18.914, P = 0.003) in multivariate logistic regression. ROC analysis revealed that the optimal cutoff of CO₂-CP to predict CI-AKI was 22.00 mmol/L (sensitivity 64.0%, specificity 79.1%, AUC = 0.714).

CONCLUSIONSPre-percutaneous coronary intervention CO₂-CP in patients with ST segment elevation myocardial infarction undergoing percutaneous coronary intervention is related to CI-AKI. CO₂-CP < 22.00 mmol/L predicts higher risk of CI-AKI in this patient cohort.

Objective:To investigate the current status of maternal body image during pregnancy, mother-infant attachment and postpartum depression and explore the mediating effect of mother-infant attachment on maternal body image during pregnancy and postpartum depression, in order to effectively reduce the incidence of postpartum depression and provide reference and guidance for alleviating depressive symptoms.Methods:A total of 362 pregnant women admitted to obstetric wards in Women′s Hospital of Nanjing Medical University were selected for a cross-sectional investigation by applying the Edinburgh Postnatal Depression Scale, the Body Image in Pregnancy Scale and the Maternal Postnatal Attachment Scale by convenient sampling from July to September 2022. Model 4 in the SPSS macro program PROCESS was used to test the mediating effect of maternal infant attachment between body image and postpartum depression.Results:Totally 362 valid questionnaires were retrieved including 194 individuals aged ≤30 years old and 168 individuals aged >30 years old. The scores of maternal body image during pregnancy, mother-infant attachment and postpartum depression were (89.24 ± 15.56), (71.40 ± 8.05), 7.50 (4.00, 11.00) points.Conclusions:Body image during pregnancy can not only directly predict postpartum depression, but also indirectly predict postpartum depression through the mediating effect of mother-infant attachment. In order to prevent or reduce the occurrence of postpartum depression, nursing staff should carry out intervention research based on influencing the path of postpartum depression from the perspective of positive psychology.
