		                        			A combined epidemic prediction method based on multi-source data fusion is presented to address the common problems of low accuracy,weak generalization,single structure,poor nonlinear processing ability,and long prediction time in traditional epidemic prediction models.The collected multi-source epidemic data are normalized and subjected to feature selection using principal component analysis.An ARIMA-GM-BPNN model for pandemic prediction is constructed by combining ARIMA model,grey GM model and BPNN.The fitting values of the first two prediction models are used as inputs to BPNN for model training.After sufficiently integrating the data and combining the advantages of different prediction models,the optimal combined model is obtained and used for forecasting the incidence and trend of epidemics.Experimental results show that the combined model exhibits excellent fitting performance,with predicted incidences and trends consistent with the real conditions.The proposed approach improves prediction accuracy and generalization capabilities,and it can provide reliable data support for epidemic prediction and control.

		                        			Objective:To evaluate the relationship between gluten-free diet and rheumatoid arthritis (RA).Methods:Data were obtained from large-scale genome-wide association studies (GWAS), and genetic loci that are independent of gluten-free diet and RA of people of Europe2 were selected as instrumental variables. The gluten-free diet GWAS data included 64 949 individuals and 9 851 867 controls. Data were obtained from GWAS of 58 284 RA patients and 13 108 512 controls. The inverse variance weighted (IVW), MR Egger, weighted median method and weighted model were used to conduct two sample Mendelian randomization (MR) analysis. Cochran Q test and mendelian randomness pleiotropy residual sum and outlier (MR-PRESSO) were used to assess SNP heterogeneity. Applying the MR Egger intercept to test the level pleiotropy of SNP. The sensitivity analysis of the "leave one method" that evaluates whether MR studies were influenced by a single SNP. Results:After matching GFD and RA data, three SNPs were included as instrumental variables in the study. IVW showed that GFD could significantly reduce the risk of RA ( β=-60.83, s x=3.82, P<0.001). The weighted median method and weighted pattern also showed that the gluten free diet could reduce the risk of RA ( β=-57.97, s x=4.41, P<0.001; β=-55.81, s x=5.10, P=0.008). Sensitivity analysis of the correlation between GFD and RA showed that there might be heterogeneity between SNPs (Cochran Q test, Q=12.80, P=0.002). The MR-PRESSO results showed that no abnormal SNP was detected ( P=0.174). The forest map showed that SNPs was closely related to GFD and RA stability. The method comparison chart showed that the results of multiple testing methods were basically consistent. The funnel plot showed that SNPs were basically symmetrical, indicating that there was no pleiotropy in MR analysis. The MR Egger intercept test showed no horizontal pleiotropy in MR analysis (intercept value was-0.24, P=0.174). The sensitivity analysis of the "leave one method" is suggested that no single SNP had a significant impact on the overall results. Conclusion:Gluten free diet is related to the risk reduction of RA.

		                        			Objective To investigate the effects of electroacupuncture on the intestinal NIMA-related kinase 7(NEK7)/NOD-like receptor thermal protein domain associated protein 3(NLRP3)signaling pathway in mice with Parkinson's disease.Methods According to the randomized number table method,36 C57BL/6 mice were randomly divided into the control group,the model group,and the electroacupuncture group,with 12 mice per group.The Parkinson's disease mouse model was established by gavage of rotenone solution(10 mg/kg)for 28 d.After molding,the electroacupuncture group was stimulated with"Fengfu"(DU17),"Taichong"(LR3),and"Zusanli"(ST36)for 14 d,while the control group and the model group were only treated with immobilization.The motor ability of mice was detected by pole climbing test and hindlimb rating score,the positive expressions of nigral tyrosine hydroxylase(TH)and colon occludin were detected by immunohistochemistry,the histological morphology of colon was observed by hematoxylin-eosin staining,and Western blotting was used to detect the protein expressions of NEK7,NLRP3,Caspase-1,and interleukin-1β(IL-1β).Results Compared with the control group,mice in the model group had lower score on the pole climbing test and a higher hindlimb rating score(P<0.01);the average optical densities of nigral TH and colon occludin were decreased(P<0.01);significant inflammatory infiltration was observed in the colonic tissue,and the muscularis propria was thinned;and the protein expressions of NEK7,NLRP3,Caspase-1,and IL-1β in the colonic tissue were elevated(P<0.01).Compared with the model group,mice in the electroacupuncture group had higher score on the pole climbing test and a lower hindlimb rating score(P<0.01);the average optical densities of nigral TH and colon occludin were increased(P<0.01);the degree of inflammatory infiltration of colonic tissues decreased,and the muscularis propria was thickened;and the protein expressions of NEK7,NLRP3,Caspase-1,and IL-1β of colonic tissues were decreased(P<0.01).Conclusion Electroacupuncture at"Fengfu"(DU17),"Taichong"(LR3),and"Zusanli"(ST36)can improve motor functional impairments in mice with Parkinson's disease,and the mechanism may be through the inhibition of intestinal NEK7/NLRP3 pathway,improving the intestinal barrier damage,relieving the intestinal inflammation,and improving the dopaminergic neuron injury.
