ObjectiveTo understand the distribution of interleukin(IL)-28B gene polymorphisms in human immunodeficiency virus (HIV)/hepatitis C virus (HCV) coinfected Han patients in Hubei Province.MethodsOne hundred Han patients with anti-HIV and anti-HCV double positive in Hubei Province were enrolled.HCV RNA level was detected by fluorescence quantitative polymerase chain reaction (PCR) and genotyping of IL-28B gene was pcrformed by sequencing.The data were analyzed by chi square test.ResultsThe proportion of IL-28B C/C genotype was 95.0 ％ in target population,arnong which 21.1％ (20/95) were HCV RNA negative.While there were no HCV RNA negative cases in C/T and T/T genotypes (0/5;x2 =1.043,P=0.588).ConclusionAmong HIV/HCV coinfccted Han patients in Hubei Province,the proportion of IL-28B C/C genotype is high.

OBJECTIVETo assess the association of polymorphisms of N-acyl-phosphatidylethanolamine-phospholipase D (DAPE-PLD) and fatty acid amide hydrolase (FAAH) genes, as well as their interaction, with schizophrenia.
METHODSPolymorphisms of NAPE-PLD rs12540583 and FAAH rs324420, rs2295633, and rs6429600 were determined with PCR - restriction fragment length polymorphism assay and Sanger sequencing. The genotypes of 345 subjects of Han Chinese origin diagnosed with schizophrenia and a 403 controls were compared. The results were analyzed with SPSS 17.0, and the interaction of the two genes was analyzed using a multifactor dimensionality reduction (MDR) method.
RESULTSThe frequency of NAPE-PLD rs12540583 polymorphism was significantly different between the two groups under both dominant and additive models (χ2=17.18 vs. χ2=18.94, P<0.0125). The frequencies of AC genotype and C allele of the patient group at rs12540583 were higher than those of the controls, and the interaction of NAPE-PLD and FAAH was associated with schizophrenia. A four-loci model (rs12540583, rs324420, rs2295633 and rs6429600) can best model the interaction between NAPE-PLD and FAAH.
CONCLUSIONThe AC genotype and C allele of NAPE-PLD rs12540583 locus are risk factors for schizophrenia, and the interaction between NAPE-PLD rs12540583 and FAAH rs324420, rs2295633 and rs6429600 is associated with schizophrenia.
