ObjectiveTo investigate the association of BANK1 single nucleotide polymorphisms (SNPs) with rheumatoid arthritis(RA) in Chinese Han. MethodsTwo hundreds and twenty-one RA patients and 310 healthy controls who were Chinses Han population from Huashan Hopital and Changzheng Hospital in Shanghai,China were included.DNAs were extracted from peripheral whole blood for study.Samples were genotyped for three variants rs10516487,rs17266594 and rs3733197 in BANK1 by unlabelled probe high resolution melting (HRM) assay.The genotype frequencies of the detected polymorphisms were analyzed in relation to RA and the production of autoantibodies in RA patients.ResultsThe Tr genotype frequency was much higher in RA patients than in healthy controls(X2=6.241,P=0.044).The frequencies of rs10516487 G allele,rs17266594 T allele and rs3733197 G allele were increased among RA patients compared with healthy controls,although they didn't reach statistical significance.The rs10516487 and rs17266594 were found in strong linkage disequilibrium(D'=0.993,r2=0.985).And also the major TGG haplotype of 3-SNP was significantly associated with RA patients[P=0.037,OR =1.345,95%CI (1.018-1.776)].ConclusionBANK1 rs17266594 polymorphism is susceptible to RA,while rs10516487 and rs17266594 are linked in Chinese Han population.BANK1 SNPs TGG haplotype may contribute to RA susceptibility,too.

Objective To analyze the risk factors of stroke-associated pneumonia (SAP) in patients with acute ischemic stroke (AIS) treated with intravenous thrombolysis.Methods A total of 798 patients with AIS who received intravenous thrombolysis therapy with alteplase from the Department of Neurology,Yangpu Hospital,Tongji University from January 2016 to December 2020 were retrospectively selected and divided into pneumonia group and non-pneumonia group according to the presence or the absence of SAP.The clinical of the two groups were compared.Multivariate logistic regression analysis was used to analyze the independent risk factors of SAP.Results Of 798 cases,115 cases occurred SAP.By multivariate logistic regression analysis,age≥70 years(OR=2.846,95%CI 2.311~5.083,P<0.001),diabetes(OR=2.291,95%CI 1.601~3.945,P=0.003),chronic obstructive disease(OR=2.064,95%CI 1.759~3.528,P=0.005),NIHSS score at admission>8(OR=1.814,95%CI 1.502~2.452,P<0.001),unconsciousness(OR=2.325,95%CI 2.005~3.404,P=0.008),dysphagia(OR=2.457,95%CI 2.221~4.017,P<0.001),hemorrhagic transformation(OR=1.828,95%CI 1.653~2.523,P=0.012) were independent risk factors of SAP in AIS patients treated with intravenous thrombolysis.Conclusion Age≥70 years,diabetes,chronic pulmonary disease,NIHSS score at admission,unconsciousness,dysphagia,hemorrhagic transformation were independent risk factors of SAP in AIS patients treated with thrombolysis.
