Occupational chronic psychological stress and transaminase,HSP70 gene family and its proteins association of the interaction with metabolic syndrome
OBJECTIVE To explore the association of Occupational chronic psychological stress with transaminase,heat shock protein70(HSP70)gene family and their protein interaction with metabolic syndrome(MS).METHODS A case-control study was used.According to the inclusion and exclusion criteria,from March 2015 to March 2016,583 unrelated MS patients were selected as the case group and 585 unrelated healthy people as the control group among hospitalized and physical examination subjects aged 20-60 in Wuzhong People's Hospital and General Hospital of Ningxia Medical University.Questionnaire survey,physical examination,clinical and biochemical indicators,serum HSP70 level and five-locus polymorphism detection of HSP70 gene were carried out.GMDR 0.7 software was used to analyze the relationship between psychological stress,transaminase,HSP70 gene and its protein interaction and MS.RESULTS After adjusting for age and sex,the rs1008438,rs1061581,rs539689 and rs222795 locus of HSP70 gene in the Co-dominant model and Dominant model and the rs222795 loci in the Over-dominant model carry wild homozygous genotype and heterozygous genotype were all related to the reduction of MS risk(OR＜1,P＜0.05).GMDR result:the 2-factor interaction model composed of psychological stress and serum HSP70,the 2-3 factor interaction model composed of transaminase activity,and the 2-6 factor interaction model composed of five locus of HSP70 gene,the 2-9 factor interaction model consisting of psychological stress and transaminase activity,HSP70 gene and its protein were all significantly associated with MS(P＜0.01,P＜0.05),all each factor interaction models were the best,and the 9-factor optimal interaction model had the highest risk of MS(OR=46.51,95％ CI 27.65-78.26),and the risk of MS in high-risk type was 45.23 times higher than that in low-risk type(95％ CI 31.29-65.38,P＜0.01).CONCLUSION HSP70 gene family carrying wild-type alleles is a protective factor for MS.The interaction among Occupational chronic psychological stress interacts with transaminases,HSP70 gene and its serum proteins may be associated with MS.With the increase of involvement interaction factors,the risk of MS increased significantly.The interaction of multiple factors can greatly increase its risk.
