BACKGROUND:silencing information regulatory 1(SIRT1)regulates the function of related proteins in chondrocytes in a deacetylated manner and participates in chondrocyte proliferation and differentiation,thereby promoting cartilage defect repair. OBJECTIVE:To screen for signaling pathways with unclear action status after SIRT1 gene knockdown in chondrocytes,as well as diseases or functions that produce changes using high-throughput technology. METHODS:ATDC5 chondrocytes from mice in logarithmic growth phase were divided into two groups:the cells were transfected with SIRT1 gene knockdown negative control lentivirus in control group and SIRT1 gene knockdown lentivirus in experimental group.GeneChip? Mouse Genome 430 2.0 Array was used to detect the mRNA expression at 72 hours after transfection.Applied bioinformatics technology was also used to screen for unclear activation or inhibition signaling pathways and their related factors.Moreover,enrichment of disease or function modules was analyzed. RESULTS AND CONCLUSION:After knocking down the SIRT1 gene,there were 245 signaling pathways with unclear activation or inhibition status in the mouse ATDC5 chondrocytes.According to the ranking of-Log(P-value),we reported the factors in the top 20 signaling pathways with unclear activation or inhibition status,including IGFBP4,TGFBR1,CTGF,COL4A5,LHX2,IL1RL1,and KLF6.According to the ranking of-Log(P-value),there were significant changes in 14 disease or function modules,including cellular growth and proliferation,organism survival,cell death and survival.According to the number of differentially expressed genes,there were significant changes in three disease or function modules,including organismal injury and abnormalities,cancer,and cell death and survival.According to the comprehensive ranking of-Log(P-value)and the number of differentially expressed genes,the disease or function module related to intrinsic immune response was significantly activated.

Objective To develop a health-promoting lifestyle scale for women with polycystic ovary syndrome(PCOS),and to test its reliability and validity,and preliminarily apply it.Methods Based on the Pender health promotion model,the item pool of the scale was constructed through literature research,semi-structured interviews and group discussions.After 2 rounds of Delphi expert consultation and pre-survey,the initial scale was formed.From April to July 2022,316 patients with PCOS in the health management center,reproductive medicine center and endocrinology department of a tertiary hospital in Nanjing were selected for item analysis,exploratory factor analysis and reliability test,respectively.From August to October 2022,358 PCOS patients were selected for confirmatory factor analysis.From November 2022 to February 2013,294 PCOS patients were selected,and the scale was used to investigate the status of health-promoting lifestyle in PCOS patients.Results The health-promoting lifestyle scale for PCOS patients included 5 dimensions and 33 items.The total content validity index of the scale was 0.942,and the content validity index of each item was 0.810-1.000.5 common factors were extracted by 2 exploratory factor analyses,and the cumulative variance contribution rate was 62.399％.Confirmatory factor analysis showed that the model fit was good.The Cronbach's a coefficient of the total scale was 0.930;the split-half reliability was 0.842;the test-retest reliability was 0.888.The preliminary application results showed that the total score of health-promoting lifestyle in PCOS patients was(96.925±14.273),and the average score of items was(2.937±0.433),which was at a medium level.Conclusion The health-promoting lifestyle scale for PCOS patients has good reliability and validity,which can be used as a tool for medical staff to assess the level of health-promoting lifestyle of PCOS patients,and can help nurses to quickly identify the level and dimensions of health-promoting lifestyle of patients,so as to formulate individualized precise health management plans.

We reported a 32 years female patient in whom lung metastasis from breast cancer was presented as solitary pulmonary pure ground-glass opacity (GGO) lesion. The patient received rational preoperative examinations and surgery though the preoperative diagnosis was not accurate. Because of different therapy strategies and purposes, it is crucial to make distinction of atypical metastases from primary cancers. Thus, for patients with a history of malignancy, possible metastasis should be taken into consideration if new GGO was found on the CT. Besides this, the follow-up interval of CT should be shortened appropriately, preoperative examinations and surgical procedures should be made according to the suggestions of multidisciplinary team.

Objective To research the procedure for creating an animal model of mitral regurgitation by implanting a device through the apical artificial chordae tendineae, and to assess the stability and dependability of the device. Methods Twelve large white swines were employed in the experiments. Through a tiny hole in the apex of the heart, the artificial chordae tendineae of the mitral valve was inserted under the guidance of transcardiac ultrasonography. Before, immediately after, and one and three months after surgery, cardiac ultrasonography signs were noted. Results All models were successfully established. During the operation and the follow-up, no swines died. Immediately after surgery, the mitral valve experienced moderate regurgitation. Compared with preoperation, there was a variable increase in the amount of regurgitation and the values of heart diameters at a 3-month follow-up (P<0.05). Conclusion In off-pump, the technique of pulling the mitral valve leaflets with chordae tendineae implanted transapically under ultrasound guidance can stably and consistently create an animal model of mitral regurgitation.

Objective:To describe demographic,clinical and physiological characteristics,treatment between first-episode major depressive disorder(MDD)and relapse MDD,and to explore characteristics of relapse MDD.Methods:Totally 858 patients who met the diagnostic criteria for depression of the Diagnostic and Statistical Manual of Mental Disorders,Fifth Edition(DSM-5),were included by using the Mini International Neuropsychiatric Interview(MINI),Clinician-Rated Dimensions of Psychosis Symptom Severity,and Hamilton Depression Scale etc.Among them,529(58.6％)were first-episode depression and 329(36.0％)were relapsed.The differences of demographic characteristics,clinical and physiological characteristics,treatment were compared byx2test and Kruskal-Wallis rank sum test.Multivariate logistic regression was used to explore the characteristics of MDD recur-rence.Results:Compared to first-episode MDD,relapse MDD had more comorbidity(OR=2.11,95％CI:1.00-4.44),more days out of role(OR=1.26,95％CI:1.01-1.56),more history of using psychiatric drug more than one month(OR=1.41,95％CI:1.02-1.97)and electroconvulsive therapy(OR=3.23,95％CI:1.42-7.36),and higher waist-hip ratio(OR=33.88,95％CI:2.88-399.32).Conclusion:Relapse MDD has positive as-sociation with comorbidity of mental disorders,out of role,and higher waist-hip ratio.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective To explore the predictive value of blood pressure variability for long-term prognosis in elderly hypertension patients with coronary heart disease(CHD).Methods A total of 272 elderly patients with CHD and hypertension admitted to our hospital from January 2015 to January 2018 were enrolled retrospectively,and all of them were followed up for 5 years.Accord-ing to that they had adverse cardiovascular events or not,they were divided into adverse cardio-vascular events group(n=102)and control group(n=170).The differences in clinical features were compared between the two groups.ROC curve was plotted to analyze the value of blood pressure variability at first admission in predicting adverse cardiovascular events in elderly hyper-tension patients with CHD.Multivariate logistic regression analysis was applied to identify the risk factors for adverse cardiovascular events in these patients.Results Compared with the con-trol group,the incidence of diabetes,the proportion of coronary artery stenosis＞75％,and 24-hour SBP variability were significantly higher in the adverse cardiovascular events group(P＜0.05,P＜0.01).The area under curve value of 24-hour SBP variability in predicting adverse cardio-vascular events in elderly patients with CHD and hypertension was 0.777(95％CI:0.720-0.835,P=0.000).24-hour SBP variability ≥11.71 mm Hg(1 mm Hg=0.133 kPa,OR=5.017,95％CI:2.911-8.647,P=0.000),diabetes(OR=2.479,95％CI:1.231-4.993,P=0.011),and coronary artery stenosis＞75％(OR=2.303,95％CI:1.022-5.190,P=0.044)were independent risk factors for adverse cardiovascular events in elderly patients with CHD and hypertension.Conclusion 24-hour SBP variability can be used to predict the occurrence of adverse cardiovascu-lar events in elderly hypertension patients with CHD.

Objective To investigate the efficacy of Jianpiwenyang Gel(SSWYG)for treating chronic diarrhea and explore its therapeutic mechanism.Methods Eighty patients with chronic diarrhea of spleen and stomach weakness type were randomized into two groups for interventions with lifestyle adjustment and treatment with bifid triple viable capsules(control group,n=40)or naval application with SSWYG(treatment group,n=40)for one week,after which symptoms of chronic diarrhea were evaluated.The Chinese medicine system pharmacology analysis platform(TCMSP),GeneCards,NCBI,OMIM database and GEO database(GSE14841)were used to obtain the active ingredients and target proteins of SSWYG and chronic diarrhea-related targets.The key targets were obtained by topological analysis for Gene Ontology(GO)and KEGG analyses.The affinity and binding characteristics of SSWYG for specific targets were verified by molecular docking using AutoDock software.Results In both groups,gastrointestinal symptom rating scale(GSRS),Bristol Scale and TCM syndrome scores significantly improved after the treatments(P<0.05),and better effects were observed in the treatment group(P<0.05).Sixty-eight targets of SSWYG in treating chronic diarrhea were obtained,and 33 most probable ones were screened out by topological analysis.GO and KEGG analyses identified several chronic diarrhea-related pathways including the TNF and IL-17 pathways.Molecular docking study showed good affinity of the core components of SSWYG for the key targets CASP3,JNK,IL1B,IL6,and AKT1.JUN and CASP3 had the lowest binding energy and the highest stable binding energy with multiple major active ingredients of SSWYG.Conclusion SSWYG can significantly improve clinical symptoms of chronic diarrhea possibly by regulating the TNF and IL-17 as well as other pathways via CASP3 and JUN,suggesting a complex therapeutic mechanism of SSWYG involving multiple ingredients and targets and coordinated regulation of multiple pathways.
