ABSTRACT
Objective: To investigate the relationship between polymorphisms of rs1532624 and rs289741 loci in cholesteryl ester transfer protein (CETP) genes and atherosclerotic cerebral infarction (ACI). Methods: The CETP gene rs1532624 and rs289741 in 95 patients with ACI and 177 healthy subjects were genotyped by MassARRAY mass spectrometry. Each locus genotype and allele frequency distributions were compared. Results: The difference of allele frequency distribution between the rs1532624 (χ

ABSTRACT
OBJECTIVE@#In this paper, we will discuss if the CETP polymorphism contributes to the centenarians in Hainan island.@*METHODS@#We tested the TaqIB and I405V polymorphisms of CETP gene among 276 centenarians and 301 matched healthy individuals by AS-PCR and analyzed the data with SPSS software package (Version 19.0).@*RESULTS@#Our data indicated that allele B1 and V have the significant differences between centenarians and healthy control groups with P < 0.001.

ABSTRACT
Objective To study the immunodiagnostic potential of recombinant membrane protein Tetraspanin 2 of Schistosoma japonicum(rSjTsp2) as a diagnostic antigen. Methods The rSjTsp2 was expressed and purified as an antigen used in indirect ELISA to detect specific serum antibody against Schistosoma japonicum of rabbits that at different stages of infection, and the results were compared with those of ELISA using natural antigen (AWA) as antigen. Results The sensitivities of rSjTsp2-ELISA were 75.4% (46/61),77.6% (45/58) and 81.5% (44/54), respectively, 2, 4, 6 weeks after rabbits were infected with Schistosoma japonicum, meanwhile the sensitivities of AWA-ELISA were 68.9% (42/61),86.2% (50/58) and 88.9% (48/54), respectively. The sensitivity difference of two methods was not significant statistically (x2 = 0.652, 1.454,1.174, all P ＞ 0.05).Conclusions The rSjTsp2 is expressed successfully in vitro, and rSjTsp2 recombinant protein expressed in prokaryotic system has a certain application potential in immunodiagnosis.
