Association between UCP3 gene polymorphisms and nonalcoholic fatty liver disease in Chinese children

AIM:To confirm the hypothesis that polymorphisms of the uncoupling protein 3(UCP3)gene are associated with the occurrence of nonalcoholic fatty liver disease(NAFLD).METHODS:A total of 250 NAFLD patients(147 malesand 103 females)and 200 healthy individuals who served as controls(control,109 males and 91 females),aged between 6 and 16 years were enrolled in this study.The four non-synonymous single nucleotide polymorphisms(SNPs)in the UCP3 gene polymorphisms of rs1726745,rs3781907,rs11235972 and rs1800849,were genotyped using MassArray.Body mass index(BMI),waist and hip circumference,blood pressure(BP),fasting blood glucose(FBG),insulin and lipid profiles were measured and B-ultrasound examination was performed in all subjects.RESULTS:NAFLD patients showed risk factors for metabolic syndrome:elevated BMI,waist-to-hip ratio,BP,FBG,homeostasis model assessment-estimated insulin resistance,total triglyceride,total cholesterol and low-density lipoprotein-cholesterol,while decreased high-density lipoprotein-cholesterol level compared with the control group.The GG genotype distributions of rs11235972 in the NAFLD group differed significantly from that in the control group.We found that waist circumference between CC(58.76±6.45 cm)and CT+TT(57.00±5.59 cm),and hip circumference between CC(71.28±7.84 cm)and CT+TT genotypes(69.06±7.75 cm)were significantly different with and without rs1800849 variation(P<0.05).CONCLUSION:A higher prevalence of rs11235972 GG genotype was observed in the NAFLD group compared with the control group.No differences were observed for the other SNPs.However,there was a significant difference in body height in addition to waist and hip circumference between the CC(mutant type group)and CT+TT group with and without rs1800849 variation.

Epidemiological characteristics and risk factors of nosocomial carbapenem-resistant Enterobacteriaceae infections in children

Carbapenem-resistant Enterobacteriaceae(CRE)have spread worldwide as a global threat and CRE infection is associated with a significant mortality.However,data on epidemiology and treatment of CRE infection in children are comparatively lacking.[1]Therefore,we retrospectively conducted a matched case-control study to summarize the epidemiological characteristics,risk factors,treatment,and outcomes of nosocomial CRE infections in a children patient population,and also to identify the antimicrobial resistance and resistance genotyping of CRE isolates.
