Objective To observe the influence of different level of hyperhomocysteinemia on mRNA and protein expressions of KV1 .3 ,CaN,NFAT,IL-6 and TNF-αin lymphocytes of patients with acute ST-segment elevation myocardial infarction (STEMI).Methods We selected 90 STEMI patients and divided them into three groups according to the level of plasma homocysteine:the first experimental group (STEMI group,Hcy<1 5μmol/L, n=30),the second experimental group (STEMI with mild Hhcy group,Hcy 15~30μmol/L,n=30)and the third experimental group (STEMI with intermediate Hhcy group,Hcy>30 μmol/L,n=30 ).Another 30 healthy examined people were selected as control group (n=3 0 ).Peripheral lymphocytes were isolated by Ficoll density gradient centrifugation.The Hcy in the plasma was measured with the IMX assays.Real-time quantitative PCR (RT-PCR)was used to detect mRNA expressions of KV1.3,CnAα,NFAT1,IL-6 and TNF-αand Western blot technique was used to detect the expressions of KV1.3,CnAαand NFAT1.Results The mRNA and protein expression levels of KV1.3,CnAαand NFAT1 in each experimental group were significantly higher than those in control group (P<0 .0 5 or P<0 .0 1 ).Multiple comparison in each experimental group showed that compared with that in the first experimental group,the expression level of the second experimental group increased (P<0.05 or P<0.01)and compared with first and second experimental groups,the expression level of the third experimental group increased (P<0.05 or P<0.01).The mRNA expression levels of IL-6 and TNF-αin each experimental group were significantly higher than those in control group (P<0.05 or P<0.01 ).Multiple comparison in each experimental group showed that compared with that in the first experimental group,the expression level of the second experimental group increased (P<0 .0 5 or P<0 .0 1 )and compared with first and second experimental groups,the expression level of the third experimental group increased (P<0.01).Plasma total Hcy levels were positively correlated with mRNA and protein expressions of KV1.3 in all observed groups (r=0.503 P=0.000,r=0.726 P=0.000).Conclusion The higher level of Hcy in plasma,the higher mRNA and protein expression levels of KV1.3,CnAα,NFAT1 and the higher mRNA expression levels of IL-6,TNF-αin the lymphocyte of STEMI patients,which may be one mechanism for Hcy exacerbating the inflammatory reaction of STEMI.

Objective: To observe the clinical efficacy of long-time needle retaining at Baihui (GV 20) in treating post-stroke cognitive impairment. Methods: A total of 60 eligible patients with post-stroke cognitive impairment were randomized into a treatment group and a control group by random digital table, 30 cases in each group. The control group was intervened by basic treatment including routine therapy in Neurology department and Western medicine rehabilitation therapy, while the treatment group was intervened by same treatment in the control group combined with long-time needle retaining at Baihui (GV 20). Mental state of patients was evaluated by National Institute of Health stroke scale (NIHSS) and mini-mental state examination (MMSE) after 4 weeks of treatment. Results: After 4-week treatment, the NIHSS score dropped in both groups, and intra-group comparisons showed statistical significances (both P<0.05), and the score in the treatment group was statistically lower than that in the control group (P<0.01); the MMSE score in the treatment group was significantly higher than that in the control group, there was a statistical inter-group difference (P<0.01); the total effective rate was 93.3%, and the marked effective rate was 50.0% in the treatment group, versus 76.7% and 20.0% in the control group, there were significant differences in the total effective rate and the marked effective rate between the two groups (all P<0.05). Conclusion: Long-time needle retaining at Baihui (GV 20) can produce a safe valid therapeutic efficacy in treating post-stroke cognitive impairment.

Objective To determine the incidence and risk factors of iatrogenic retinal breaks in eyes undergoing pars plana vit- rectomy for idiopathic macular pucker.Design Retrospective case series.Participant 88 consecutive vitrectomies performed on eyes with idiopathic macular pucker.Method Consecutive vitrectomies performed on eyes with idiopathic macular pucker at Beijing Tongren Eye Center between 2002 and 2006 were retrospectively reviewed.Cases with iatrogenic retinal breaks were recorded and analyzed. Main Outcome Measure Number and location of retinal breaks,and anatomic outcome after surgical managements.Result A total of 88 consecutive vitrectomies were included in the study.Of the 88 eyes,8 eyes had 14 iatrogenic retinal breaks detected,with an aver- age incidence of 9.1%.Peripheral retinal breaks(8.0%)were more common than posterior retinal breaks(1.1%).All peripheral retinal breaks occurred around the selerotomy sites(100%)and the quadrant of predominant hand was involved most commonly(62%).Most of the breaks(88%)were detected during the surgery.All eyes with iatrogenic retinal breaks obtained anatomic retinal reattachment (100%).Conclusion Despite improvements in instrumentation and surgical techniques,iatrogenic retinal break continues to be an im- portant complication of pars plana vitrectomy in eyes with idiopathic macular pucker.This complication tends to occur more commonly at peripheral retina and is mainly selerotomy-related.

OBJECTIVETo explore the association of T1270533G polymorphism in the glutathione S-transferase M1 (GSTM1) gene with the susceptibility to nasopharyngeal carcinoma (NPC) and clinical phenotype of NPC in Chinese population. METHDOS: The genomic DNAs were obtained from 27 Chinese subjects, and the single nucleotide polymorphism (SNP) in all the exons and relevant intron-exon boundaries of GSTM1 were determined by PCR and direct sequencing. A case-control study was performed to analyze the SNP site T1270533G (the rare allele frequency is 22.2% in Chinese population) in the coding region by means of tetra-primer amplification refractory mutation system-polymerase chain reaction (ARMS-PCR) and sequencing.

RESULTSequence analysis identified 29 SNPs in GSTM1 gene, among which 13 SNPs presented high linkage disequilibrium with each other. No obvious relations were found between the variation in the coding region T1270533G and the clinical phenotype of NPC (RR=0.170, 95% CI =0.95-0.306 for TT homozygotes).

CONCLUSIONThe missense mutation in the coding region T1270533G of GSTM1 gene that causes an amino acid change does not affect the detoxification function of GSTM1, and the T1270533G polymorphism does not have apparent relations to NPC susceptibility in Chinese subjects in Guangdong Province.

In this study, we cloned the NS3 gene from bovine viral diarrhea virus (BVDV) VEDEVAC strain. The result showed that the average P-distance of Pestivirus NS3 amino acid sequence was 0.07 and the VEDEVAC strain was classified to BVDV type 1. Using pET-30a(+) as vector and Escherichia coli Rosetta (DE3) as host, we obtained purified recombinant NS3 protein by Ni-NTA affinity chromatography. Western blotting analysis demonstrated that both BVDV positive serum and classical swine fever virus (CSFV) positive serum were able to recognize the recombinant NS3 protein. Indirect-ELISA assay indicated that the protein could be used as detection antigen.
