Myocardial fibrosis is a common pathological manifestation of various heart diseases,with hidden onset and the possibility of evolving into irreversible heart failure.Currently,there is still insufficient diagnosis and treatment of myocardial fibrosis.Traditional Chinese medicine can regulate myocardial fibrosis at multiple levels,targets,and pathways,and has significant advantages in treating myocardial fibrosis.Its underlying mechanisms are worth further exploration.The theory of"yang generating qi,yin constituting the body"in Huangdi Neijing embodies the meaning of yin and yang,containing a profound outlook on life and disease.Pathological changes in the initial,progressive,and final stages of myocardial fibrosis conform to the yin-yang theory of"yang generating qi,yin constituting the body".Insufficient yang generating qi and excessive yin constituting the body constitutes the core pathogenesis of myocardial fibrosis.This article proposes a treatment approach for myocardial fibrosis by tonifying yang and abating yin.The treatment of warming yang,unblocking yang,removing blood stasis,resolving phlegm,detoxifying,and promoting diuresis is applied to broaden the clinical treatment approach for myocardial fibrosis.

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.

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 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.

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.

Objective:To explore the effects of online mindfulness-based stress reduction(MBSR)on the anxiety and depression status,and quality of life in the caregivers of patients with severe mental disorders.Methods:Ninety-three caregivers for patients with schizophrenia or bipolar disorder,who were hospitalized in Yunnan Provincial Mental Hospital in March 2021,were enrolled and randomly divided into control group(n=47)and MBSR intervention group(n=46).Both groups received basic health education and rehabilitation skill training,while the intervention group received additional online MBSR for 8 weeks.The anxiety and depression status,and the quality of life of the caregivers were evaluated by Self-rating Anxiety Scale(SAS),Self-rating Depression Scale(SDS)and the 36-item Short Form Health Survey(SF-36)before and 8 weeks after intervention,respectively.Results:Thirteen caregivers dropped out of the study,and 80 subjects(40 in each group)were included in the final analysis.At the baseline,there were no significant differences in SAS,SDS and SF-36 scores between two groups(all P>0.05).Compared with the baseline,SAS and SDS scores in the intervention group significantly decreased after 8 weeks of intervention(both P<0.01)and were significantly lower than those in the control group(both P<0.01).There were no significant changes in the control group(all P>0.05).Except the physiological function dimension,the total score and the scores of each dimension of SF-36 in the intervention group were significantly increased after 8-week intervention(all P<0.05),and were significantly higher than those in the control group(all P<0.01).There were no significant changes in the control group before and after intervention(all P>0.05).Conclusion:Online MBSR can reduce the anxiety and depression levels,improve the quality of life in the caregivers of patients with severe mental disorders.

In recent years, researches have shown that microglia drive their phenotype polarization through energy and substance metabolism reprogramming, thereby exerting pro-inflammatory or anti-inflammatory effects, which is closely associated with the risk of ischemic stroke. Their specific metabolic pathways involve glucose metabolism, lipid metabolism, and amino acid metabolism. This article reviews regulatory mechanisms of microglia metabolism after ischemic stroke and their role in ischemic stroke.
