Objective:To investigate the effects of combination therapy with aqueous extract of corn silk(CS)and training on exercise capacity and glycolipid metabolism in mice with metabolic syndrome(MS).Methods:In this study,db/db mice were used as the animal model of MS.The mice were administered aqueous extract of CS via gavage and subjected to different intensities of training for 12 weeks(3 months).The specific experimental design was as follows:24 db/db mice were randomly divided into four groups on average:negative control group(NC),aqueous extract of CS group(CS),aqueous extract of CS+moderate-intensity training group(CS+MT),and CS aqueous extract of CS+high-intensity training group(CS+HT).The maximum running speed,forelimb grip strength,body weight and fasting blood glucose of mice were measured before and after treatment.After the intervention,oral glucose tolerance test(OGTT)and insulin tolerance test(ITT)were conducted to assess glucose metabolism,while serum triglyceride(TG),total cholesterol(TC),high-density lipoprotein cholesterol(HDL-C),and low-density lipoprotein cholesterol(LDL-C)levels were measured to evaluate lipid metabolism.Results:After 3 months of intervention,there were significant differences in the maximum running speed and forelimb grip strength among the four groups(P＜0.05).The maximum running speed and forelimb grip strength of CS group,CS+MT group and CS+HT group were higher than those of NC group(P＜0.05).The CS+MT group exhibited higher forelimb grip strength,and the CS+HT group showed higher maximum running speed and forelimb grip strength compared to the CS group(P＜0.05),while no significant difference was found between the CS+MT and CS+HT groups(P＞0.05).Significant differences in body weight were observed among the four groups after 3 months of intervention(P＜0.05).Specifically,the CS+MT and CS+HT groups exhibited significantly lower body weight compared to both the NC and CS groups(P＜0.05),with the CS+MT group having the lowest body weight(P＜0.05).Fasting blood glucose levels also differed significantly among the groups after 2 and 3 months of intervention(P＜0.05).The CS,CS+MT,and CS+HT groups had lower fasting blood glucose levels compared to the NC group(P＜0.05),with the CS+MT and CS+HT groups showing the lowest levels(P＜0.05).No significant difference was found between the CS+MT and CS+HT groups(P＞0.05).After 3 months of intervention,significant differences in the area under the curve(AUC)of OGTT and ITT were observed among the four groups(P＜0.05).The AUC of OGTT and ITT were significantly lower in the CS,CS+MT,and CS+HT groups compared to the NC group(P＜0.05).The CS+MT and CS+HT groups exhibited the lowest AUC values for both OGTT and ITT(P＜0.05),with the CS+MT group showing the lowest AUC for OGTT(P＜0.05).Significant differences in serum lipid levels were observed among the four groups after 3 months of intervention(P＜0.05).TG,TC,and LDL-C levels were significantly lower,while HDL-C levels were higher in the CS,CS+MT,and CS+HT groups compared to the NC group(P＜0.05).The CS+MT group had the lowest TG levels and the highest HDL-C levels compared to the CS+HT group(P＜0.05),with no significant differences in TC and LDL-C levels between these two groups(P＞0.05).Conclusion:Aqueous extract of CS combined with different intensity training can significantly improve the exercise capacity and glycolipid metabolism of MS mice and reduce body weight,especially CS combined with MT treatment is more effective in improving lipid metabolism.In addition,when combined with HT,aqueous extract of CS can also play an auxiliary role in reducing the side effects of high-intensity exercise and improving the therapeutic effect.

Objective To observe the clinical effect of doing Huatuo five-animal play treating blood-stasis-type silent myocardial ischemia(SMI)and its influence on coronary hemodynamics.Methods Ninety patients diagnosed as silent myocardial ischemia were randomly divided into a five-animal play group(n=45,age:51.56±11.00 years,24 males and 21 females)and a regular exercise group(n=45,age:52.44±7.19 years old,24 males and 21 females)according to a random number table.The five-animal play group practised the traditional five-animal play,while the regular exercise group con-ducted daily 30-minute moderate-intensity treadmill aerobic exercise,five times a week,for 4 weeks.The changes in the number of abnormal ST-T segment occurrences,myocardial oxygen consumption(CMO),coronary ischemia threshold(CIT),and blood smoothness index(BSD)within 24-hour ambu-latory electrocardiogram before and after the intervention were observed in both groups,with the thera-peutic effect and hemodynamic characteristics of both groups evaluated.Results The average number of ST-T segment abnormalities decreased after intervention in both groups(P<0.001),with significantly greater improvement in the five-animal play group than the regular exercise group(P<0.001).More-over,the average CMO decreased significantly,while the average CMR and BSD increased significant-ly in both groups after intervention(P<0.05),with significantly greater improvement in the five-ani-mal play group than the other group.Meanwhile,the total effective rate in the five-animal play group was significantly higher than the regular exercise group(P<0.01).Conclusion Undergoing the five-ani-mal play and moderate intensity treadmill aerobic exercise both are effective in treating silent myocardi-al ischemia.However,the former therapy is superior to the latter in bettering CMO,CIT and BSD.

Objective:To construct a prognostic model related to cellular senescence in gastric adenocarcinoma by bioinforma-tics tools and analyze the immune microenvironment.Methods:Gene expression data and corresponding clinical information of gastric adenocarcinoma patients were downloaded from TCGA database.Cellular senescence-related genes(CSRGs)were downloaded from CellAge database.The limma package was used to screen for differentially expressed CSRGs in gastric adenocarcinoma tissues and the survival package was used to screen for CSRGs affecting the prognosis of gastric adenocarcinoma patients in R software.The LASSO regression analysis was used to construct a risk model for gastric adenocarcinoma and calculate the risk score for each patient.The Kaplan-Meier survival analysis was used to compare the overall survival(OS)of patients in high and low risk groups and the validity of prognostic models to predict 5-year survival of patients was analyzed by receiver operator characteristic curve(ROC).Univariate and multivariate Cox regression analyses were used to screen for independent prognostic factors in patients with gastric adenocarcinoma.Gene set enrichment analysis(GSEA)was used to predict potential signaling pathways in patients of high and low risk groups.Based on ESTIMATE and single sample gene set enrichment analysis(ssGSEA)algorithms to analyze the differences in tumor immune micro-environment between high and low risk groups of patients.Results:Sixteen prognostically relevant differentially expressed CSRGs were screened.The prognosis model of the genes containing AGT,EZH2,NOX4 and ZFP36 were constructed by LASSO regression analy-sis,and the patients were divided into two groups of high and low risk according to the median risk score.Survival analysis showed that patients in the high-risk group had significantly lower OS than those in the low-risk group.ROC curve analysis proved the accuracy of the prognostic model to predict the 5-year survival of patients(AUC=0.703).Then multifactorial Cox regression analysis suggested that age and risk score were independent prognostic factors for patients with gastric adenocarcinoma.GSEA enrichment analysis demonstrated that the high-risk group was associated with signaling pathways such as epithelial mesenchymal transition,hypoxia,and angiogenesis,while the low-risk group was associated with signaling pathways such as G2M checkpoint,DNA repair,and peroxisome.Further analy-sis showed that patients in the high-risk group had a higher abundance of immune cell infiltration and higher levels of immune check-point-related gene expression.Conclusion:In this study,a new prognostic model related to cellular senescence in gastric adenocarci-noma was constructed,in which patients in the high-risk group had higher immunoreactivity.

Aim To investigate the protective effect of Siwu decoction(SWD)on immune injury induced by 60Coγ-rays in mice and the related mechanism.Meth-ods C57BL/6J mice were randomly divided into six groups:Control group(Control),Model group(Mod-el),Siwu decoction low-dose group(SWD-L),Siwu decoction medium-dose group(SWD-M),Siwu decoc-tion high-dose group(SWD-H)and resveratrol positive group(Resveratrol,Res).The drug was continued to be administered 11 days before and after irradiation,with a single whole-body irradiation of 4 Gy,and all in-dexes were detected three days after irradiation.The changes of peripheral blood and organ indexes were de-tected.Serum levels of cytokine interferon gamma(IFN-γ),interleukin-1 β(IL-1 β),IL-2,IL-4,IL-6,IL-10,IL-17,transforming growth factor-β(TGF-β),tumor necrosis factor(TNF)-α,and immunoglobulin A(IgA),IgG,IgM,and complement protein 3(C3),C4 content were detected by enzyme-linked immunosorbent assay(ELISA).B lymphocytes,T lymphocytes,NK cells in spleen and T lymphocytes in thymus were de-tected by flow cytometry.The pathological changes of spleen and thymus were analyzed by hematoxylin-eosin(HE)staining.The expression of Sirt 1 protein in spleen after radiation was detected by immunofluores-cence staining.The protein contents of Sirt1,PI3K,Akt,p-Akt and mTOR in spleen were detected by Western blot assay.Results SWD could significantly increase LYMPH％and reduce pathological injury of spleen and thymus.Flow cytometry showed that SWD could significantly increase the percentage of CD19+B lymphocytes in spleen,decrease the percentage of NK lymphocytes and the ratio of CD4+/CD8+in spleen and thymus.ELISA results showed that SWD signifi-cantly inhibited the expression of IL-1 β,IL-2,IL-6,IL-17,IFN-γ,TGF-β,TNF-α,and increased the content of anti-inflammatory factors IL-4 and IL-10.At the same time,SWD significantly inhibited the increase of IgA,IgG,IgM,C3 and C4 induced by radiation.The results of immunofluorescence staining and Western blot showed that SWD could decrease the expression of PI3K,Akt,p-Akt and mTOR protein,and enhance the expression of Sirt1 protein.Conclusions SWD has obvious preventive effect on immune damage induced by 60Co gamma radiation in mice.The mechanism may be related to Sirt1-PI3K-Akt-mTOR.
