Aim To investigate the effects of berberine on extracellular matrix in rat glomerular mesangial cells cultured under high glucose and its possible mechanism.Methods Six groups were divided according to the different experimental conditions:① Normal glucose group (NG);② Mannitol group (Mannitol);③ High glucose group (HG);④ SB203580 treatment group (HG+SB203580);⑤ Berberine low dosagegroup (HG+BBR 30 ?mol?L-1);⑥ Berberine high dosage group (HG+BBR 90 ?mol?L-1). The phospho-p38MAPK,phospho-cAMP response element binding protein (CREB) and fibronectin were detected by Western blot analysis. Results Berberine obviously decreased protein expression of fibronectin compared with high glucose group. Phospho-p38MAPK and phospho-CREB level was significantly lowered compared with that of high glucose group. Conclusion Berberine can inhibit extracellular matrix accumulation including fibronectin via p38MAPK signal pathway in treatment of diabetic nephropathy.

To explore the clinical efficacy and possible mechanism of Tai Ji Quan for post-stroke depression (PSD), literature related to Tai Ji Quan and PSD were retrieved from China National Knowledge Infrastructure (CNKI), Wanfang Academic Journal Full- text Database (Wanfang), Chongqing VIP Database (CQVIP), China Biology Medicine Disc (CBM), and PubMed, screened and then summarized. The results showed that Tai Ji Quan could effectively improve the depression and quality of life of stroke patients, and there were differences in the clinical efficacy among different training programs. Tai Ji Quan has the characteristics of "regulating mind", "regulating breath", and "regulating body". It may achieve the effect of "combined physique-spirit treatment" by improving social psychology, increasing the level of neurotrophin, regulating neuroendocrine, reducing inflammatory factors, and regulating neural circuits.

Objective:
To explore the biological characteristics of synovial fluid-derived mesenchymal stem cells (SF-MSCs) cultured in serum-free medium and the ability of in vitro reconstruction of three-dimensional cartilage combined with scaffold material.
Methods:
Human SF-MSCs were cultured in serum medium and mesenchymal stem cells medium-serum free (MSCM-sf) respectively, then the proliferative ability and morphology of SF-MSCs were compared; The third passage SF-MSCs cultured in MSCM-sf were identified by flow cytometry, three-way(chondrogenic, osteogenic, adipogenic)differentiation assay and induced for chondrogenic differentiation when combined with polyglycolic acid/polylactic acid (PGA/PLA).
Results:
SF-MSCs cultured in MSCM-sf had better morphology and proliferative ability than that cultured in serum medium. The expression levels of positive markers of the third passage SF-MSCs cultured in MSCM-sf, such as CD73 (99.5%), CD90 (98.9%) and CD105 (96.5%), were more than 95%. However, the overall negative markers (CD34, HLA-DR and CD11b) expressed less than 2%. Three-way differentiation staining was positive. The combination of SF-MSCs and PGA / PLA can be induced into cartilage in vitro.
Conclusions
SF-MSCs cultured in MSCM-sf can be amplified under the condition of maintaining the stem cell characteristics, and can be combined with PGA/PLA scaffold to construct three-dimensional cartilage in vitro.

Objective:To analyze the hepatic tissue inflammatory activity and influencing factors in HBeAg-positive patients during normal alanine aminotransferase (ALT) and indeterminate phases so as to provide a basis for evaluating the disease condition.Methods:Patients with HBeAg-positive with normal ALT and HBV DNA levels below 2 × 10 7 IU/ml from January 2017 to December 2021 were selected as the study subjects. A histopathologic liver test was performed on these patients. Age, gender, time of HBV infection, liver function, HBsAg level, HBV DNA load, genotype, portal vein inner diameter, splenic vein inner diameter, splenic thickness, and others of the patients were collected. Significant influencing factors of inflammation were analyzed in patients using logistic regression analysis, and its effectiveness was evaluated using receiver operating characteristic (ROC) curves. Results:Of the 178 cases, there were 0 cases of inflammation in G0, 52 cases in G1, 101 cases in G2, 24 cases in G3, and one case in G4. 126 cases (70.8%) had inflammatory activity ≥ G2. Infection time ( Z=-7.138, P<0.001), γ-glutamyltransferase ( t ?=-2.940, P=0.004), aspartate aminotransferase ( t ?=-2.749, P=0.007), ALT ( t ?=-2.153, P=0.033), HBV DNA level ( t ?=-4.771, P=0.010) and portal vein inner diameter ( t ?=-4.771, P<0.001) between the ≥G2 group and < G2 group were statistically significantly different. A logistic regression analysis showed that significant inflammation in liver tissue was independently correlated with infection time [odds ratio (OR)=1.437, 95% confidence interval ( CI): 1.267-1.630; P<0.001)] and portal vein inner diameter ( OR=2.738, 95% CI: 1.641, 4.570; P<0.001). The area under the curve (AUROC), specificity, and sensitivity for infection time and portal vein inner diameter were 0.84, 0.71, 0.87, 0.72, 0.40, and 0.95, respectively. Conclusion:A considerable proportion of HBeAg-positive patients have inflammation grade ≥G2 during normal ALT and indeterminate phases, pointing to the need for antiviral therapy. Additionally, inflammatory activity has a close association with the time of infection and portal vein inner diameter.

Objective:To evaluate the teaching effect of Emergency Nursing practice course using scenario simulation teaching combined with formative assessment. Methods:The subjects were selected from vocational nursing students of Batch 2015 (control group, n=49) and Batch 2016 (intervention group, n=40). The control group adopted the scenario simulation teaching method, and the intervention group added formative assessment on the basis of simulation teaching. The end-of-term theoretical scores of Emergency Nursing and the scores of students' general self-efficacy scale were used as evaluation tools. SPSS 22.0 statistical software was used for data processing and analysis. Results:The scores of the intervention group (85.20±8.05) were higher than those of the control group (79.73±8.46), with statistical significance ( P<0.05). The scores of self-efficacy in both groups were improved, while the scores of the control group after the course (2.68±0.42) were higher than those before the course (2.61±0.47), but there was no statistical significance. The scores of the intervention group after the course (2.78±0.43) were higher than those before the course (2.62±0.43), with statistical significance. Conclusion:The application of scenario simulation teaching combined with formative assessment in the practical course of Emergency Nursing can be helpful to improve students' self-efficacy and comprehensive ability of first aid.
