Diabetes mellitus (DM) is a major metabolic disease endangering global health, with diabetic nephropathy (DN) as a primary complication lacking curative therapy. Sporoderm-broken spores of Ganoderma lucidum (GLP), an herbal medicine, has been used for the treatment of metabolic disorders. In this study, DN was induced in Sprague-Dawley rats using streptozotocin (STZ) and a high-fat diet (HFD), and the protective mechanisms of GLP were investigated through transcriptomic, metabolomic, and network pharmacology (NP) analyses. Our results demonstrated that GLP intervention ameliorated renal damage and inflammation levels in DN rats. Integrative metabolomic and transcriptomic analysis revealed that GLP treatment modulated glucose and cellular energy metabolisms by regulating relevant genes. GLP significantly suppressed the inflammations by impacting glucose and energy metabolism-related gene expression (Igfbp1 and Angptl4) and enhanced metabolic biomarkers of 4-Aminocatechol. In addition, NP analysis further indicated that GLP may efficiently alleviate DN via immune-related pathways. In conclusion, this study provides supportive evidence of the anti-inflammatory effects of GLP supplements, highlighting their potential for promising clinical applications in treating DN.

Objective·To analyze the epidemiological characteristics of risk factors for cardiovascular diseases and malignant tumors based on the Shanghai community elderly cohort.Methods·The study subjects were selected from the Shanghai community elderly cohort established from February to August 2019,with a total of 17 948 people.The study subjects were divided into 4 groups according to self-reported presence or absence of tumors and/or cardiovascular diseases during the baseline survey:tumor-free and non-cardiovascular disease group,single cardiovascular disease group,single tumor group and tumor cardiovascular disease co-occurrence group.The differences among the four groups of subjects were collected and compared in terms of demographic characteristics and physiological indicators,daily living habits(smoking,drinking tea,drinking coffee,drinking carbonated drink,drinking alcohol,sedentary time,physical activity level and sleep quality),past medical history,psychological status(depression and anxiety)and dietary compliance.Results·Among the study subjects,60.1%of tumor patients were complicated with cardiovascular diseases.The differences among the four groups of subjects in age,gender,educational level,pre-retirement occupation,waist circumference,hip circumference and body mass index were statistically significant(all P<0.05).Compared with the tumor-free and non-cardiovascular disease group,the single cardiovascular disease group,single tumor group and tumor cardiovascular disease co-occurrence group all exhibited lower proportions of smoking and high physical activity levels(all P<0.05),and higher proportion of sedentary time exceeding 4 h/d and poor sleep quality(all P<0.05);the proportion of subjects with past medical histories including hyperlipidemia,peripheral vascular disease,endocrine system disease,respiratory system disease,urinary system disease and digestive system disease of the single cardiovascular disease group and the tumor cardiovascular disease co-occurrence group was higher(all P<0.05),and the proportion of subjects with depression and anxiety was also higher(all P<0.05).Furthermore,compared with the tumor-free and non-cardiovascular disease group,the single cardiovascular disease group had lower compliance rates of poultry,fish,fruit and liquid milk(all P<0.05).Among the four groups,only the compliance rate of vegetable intake exceeded 50%,while the compliance rates of poultry,fish,fruit,liquid milk and tubers were all below 20%.Conclusion·In the elderly population of Shanghai communities,over half of malignant tumor patients are concomitant with cardiovascular diseases.Unhealthy daily habits are prevalent among those with cardiovascular diseases,tumors and tumor-cardiovascular disease co-occurrence.The intake of many foods in the elderly of the community do not reach the levels recommended by Chinese Dietary Guidelines.

Objective To investigate the regulatory effect of artemisinin derivative dihydroartemisinin(DHA)on anti-tumor immune function of CD8+T cells induced by non-small cell lung cancer(NSCLC)cells.Methods NSCLC A549 cells were divided into DMSO control group and DHA treatment group.A549 cells were treated with DMSO and DHA at different concentrations(25,50 and 100 μmol/L),and the optimal concentration of DHA was selected to treat A549 cells for 0,24,48 and 72 h according to half maximal inhibitory concentrate(IC50).CCK-8 method and colony formation test were used to detect the effect of DHA on the proliferation and colony formation ability of A549 cells.Peripheral blood mononuclear cells(PBMCs)of healthy individuals were isolated by density gradient centrifugation.After monocytes were removed by adhesion method,A549 cells pretreated with mitomycin C were co-cultured with PBMCs at 10:1 ratio.After 2 weeks,flow cytometry was used to detect the proportion of CD8+T cells and the expression levels of perforin and granzyme B.Results Compared with the control group,the proliferation inhibition rates of A549 cells increased after treatment with 25,50 and 100 μmol/L DHA for 24 h(P<0.01).The IC50 of DHA on A549 cells was46.26 μmol/L.According to IC50 concentration analysis,the inhibi-tion rates of A549 cells treated with 50 μmol/L DHA for 0,24,48 and 72h were 1.53%,53.50%,63.84%and 69.91%,and the cells inhibition rates of A548 cells increased compared with the previous observation time point,namely 0,24 and 48 h(P<0.01).The colony formation assay showed that the colony formation number of A549 cells in DHA treated group decreased compared with the control group(P<0.01).Flow cytometry results showed that compared with the control group,the proportion of CD8+T cells induced by A549 cells in the co-culture system and the proportion of CD8+T cells expressing perforin and granzyme B were higher in DHA pretreatment group(P<0.01).Conclusion DHA inhibits the growth of NSCLC cells and promotes anti-tumor immune response of CD8+T cells induced by NSCLC cells.

Objective:To evaluate the efficacy and safety of noninvasive high-frequency oscillatory ventilation (nHFOV) as the initial ventilation mode for respiratory distress syndrome (RDS) in premature infants.Methods:From the establishment of the databases [(PubMed, Embase, Cochrane Library, CNKI, Wanfang database, CQVIP and CBM (SinoMed)] to March 1, 2022, literature on randomized controlled trials (RCTs) using nHFOV and nasal continuous positive airway pressure(NCPAP) as the initial ventilation modes for RDS in premature infants were searched. The qualities of the included literature were evaluated according to Cochrane Evaluation Manual. RevMan 5.4 software was used for Meta-analysis.Results:Seven RCTs involving 786 children were included for the final Meta-analysis, with 395 cases in the nHFOV group and 391 cases in the NCPAP group. The results showed that the nHFOV group had lower intubation rates than the NCPAP group ( OR=0.34, 95% CI 0.22~0.51, P<0.001). No significant differences existed in mortality rates and complication rates between the two groups ( P>0.05). Conclusions:nHFOV as the initial treatment for RDS in premature infants may reduce the incidence of early treatment failure without increasing complications.

Objective:To investigate the application effect of case-based learning (CBL) combined with flipped classroom in the teaching of experimental diagnostics in the integrated course of Diagnosis and Treatment Fundamentals. Methods:The cluster random sampling method was used to select the class of 2019 in the eight-year program and the class of 2020 in the five-year program, with the major of stomatology in Air Force Medical University.

The observation group had significantly better scores of satisfaction with teaching than the control group ( P<0.05). Conclusion:The application of CBL combined with flipped classroom in the teaching of experimental diagnostics in the integrated course of Diagnosis and Treatment Fundamentals can improve theoretical knowledge, practical skills, comprehensive quality, and satisfaction with teaching among students, and therefore, it holds promise for application in teaching.

Objective To investigate the effect of silenced RBM8A gene on the biological behavior (proliferation, migration, and apoptosis) of human endometrial cancer HEC-1A cells and its possible mechanism. Methods The hairpin shRNA targeted by the RBM8A gene was designed, and the best shRNA silencing fragment was screened. The recombinant lentiviral interference vector carrying the target gene was constructed and used to infect HEC-1A cells. Cells with stable knockdown of RBM8A gene were screened by puromycin as the experimental group (shRBM8A), while the shRNA of nonsense sequence was designed as the control group (shControl). CCK-8 method was used to detect cell proliferation, and flow cytometry was used to detect cell apoptosis. Transwell assay was used to detect cell migration and invasion. Western blot was used to analyze the expression of apoptosis-related proteins and EMT signal transduction pathway related proteins. Results In comparison with the shControl group, after RBM8A knockdown, HEC-1A cell proliferation was reduced, apoptosis was increased, migration and invasion ability were significantly inhibited (P < 0.05), the expression of apoptosis-related proteins cleaved caspase 9 and caspase 3 increased, EMT-related protein E-cadherin expression increased, and Vimentin expression decreased. Conclusion RBM8A gene silencing can inhibit the proliferation, migration, and invasion and promote the apoptosis of endometrial cancer cells. The inhibition of EMT signal transduction pathway may be its mechanism.

Objective·To compare the physical activities of stroke population and non-stroke population based on the baseline survey of the elderly population cohort in Shanghai communities,and explore the participation in different types of physical activities of stroke population.Methods·The subjects were screened from Shanghai Community Elderly Cohort constructed from February to August,2019 according to the admission criteria.The subjects were divided into non-stroke group and stroke group according to whether they had reported a history of stroke by themselves,and the two groups were matched 2 to 1 by controlling age and sex with propensity score matching.The baseline characteristics of the two groups were collected,and the physical activities related to sports,transportation and housework in the last week were investigated with the International Physical Activity Questionnaire(IPAQ).Pittsburgh Sleep Quality Index(PSQ1)was used to evaluate the sleep quality of the subjects.Generalized Anxiety Disorder(GAD-7)and Patient Health Questionnaire-9(PHQ-9)were used to evaluate anxiety and depression of the subjects,respectively.The above characteristics were compared between the stroke group and non-stroke group,and the participation of different types of physical activities were compared between the two groups by multivariate Logistic regression model.Results·Among the 17 948 people included,there were 993(5.5％)in the stroke group and 16 955(94.5％)in the non-stroke group.After propensity score matching,there were 1 984 people(66.7％)in the non-stroke group and 992 people(33.3％)in the stroke group.There were significant differences in education level,pre-retirement occupation,waist circumference,body mass index,sleep status,anxiety symptoms,depression symptoms and disease history between the two groups(all P＜0.05).In terms of physical activities,the female stroke group had shorter daily moderate exercises time,fewer riding and walking days in one week,and shorter daily riding time,compared with the non-stroke people,with statistical significance(all P＜0.05).Compared with the non-stroke people,the weekly housework days and daily housework time in the male and female stroke groups were lower than those in the non-stroke group,while the daily sedentary time was longer,with statistical significance(all P=0.000).In terms of physical activity level,the proportions of men and women in the stroke group who reached medium or high level were lower than those in the non-stroke group,and the differences were statistically significant(all P=0.000).After adjusting for gender,age,occupation,anxiety symptoms,history of hyperlipidemia,history of atrial fibrillation,history of chronic gastritis and history of hip fracture by multivariate Logistic regression model,the level of vigorous exercise participation in the stroke group was lower,the proportions of no housework in the last week and sedentary time greater than 180 min per day were higher,and the proportion at medium and high activity levels was lower(all P＜0.05).Conclusion·The frequency and duration of housework participation and the physical activity level of elderly people with a history of stroke in Shanghai communities are at a lower level than those without stroke,and they also have a longer sedentary time.
