Objective To investigate the effects of ABCB1 genetic polymorphism on the dose(D) adjusted blood concentration(C/D) of tacrolimus (TAC) and renal function in renal transplant recipients with cytochrome P450 3A5 * 3/* 3 (CYP3A5 * 3/* 3) genotype during the stable period.Methods Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was employed to detect CYP3A5 * 3 and ABCB1 genotypes;allele,genotype frequencies and Hardy-weinberg equilibrium were analysed by SHEsis software.The effects of ABCB1 polymorphism on the C/D of TAC and serum creatinine (Scr) were analyzed using SPSS 18.0 software.Results For renal transplant recipients with CYP3A5 * 3/* 3 genotype,the C/D of tacrolimus in CC genotype of ABCB1 C1236T were significantly lower than that of CT + TT genotypes (P ＜ 0.05).The Scr of GG + GA + AA + GT + AT genotypes of ABCB1 G (A) 2677T were significantly lower than that of TT genotype (P ＜ 0.05).The Scr of CC + CT genotypes of ABCB1C3435T were significantly lower than that of TT genotype (P ＜ 0.05).Conclusion ABCB1 C1236T polymorphism has an effect on the C/D of tacrolimus in renal transplant recipients with CYP3A5 * 3/* 3 genotype during the stable period.Both ABCB1 G (A) 2677T and C3435T polymorphism influence the renal function of those transplant recipients.

OBJECTIVETo analyze the molecular characteristics and genetic correlations of Vibrio cholerae isolates in Hainan in 2008, so as to provide pathogenic proof to diagnose the plague.

METHODSSeventy six cholera strains were isolated from this cholera epidemic.69 strains were obtained from patients, 7 were isolated from external environment, among which, one was from patient's toilet, one from water sample, three were isolated from fish pond near patient's home, one came from swab of the patient vomit on the ground of health center and one from swab of kitchen knife from Hainan University canteen respectively. With conventional aetiological methods, pulse-field gel electrophoresis was conducted and the patterns of the 76 isolates were analyzed. The PFGE image was analyzed using BioNumerics (Version4.0, Applied Maths BVBA, Belium). Image bands were identified and similarity coefficient was automatically generated.

RESULTSSeventy six strains were isolated from Vibrio cholerae outbreaks in Hainan in 2008.5 PFGE patterns of patient's isolates in June were the same, sharing a similarity coefficient of 100%. 70 PFGE patterns of patients and water in October and November were completely same, the similarity coefficient being 100%. But they were not same as that of June. 1 PFGE pattern of isolate from the sample in Hainan University was different, only sharing a similarity coefficient of 79.7%, which showed no correlation with the outbreak.

CONCLUSIONDifferent outbreaks of Vibrio cholera occurred in Hainan in 2008. The epidemic in October and November at different counties was one outbreak. The pollution of water in environment was an important factor for outbreak.

Hypertension is a kind of chronic cardiovascular system disease caused by a series of factors and carriers dysfunction, which belongs to the category of Tibetan medicine "Chalong disease", and has a high rate of disability and mortality. Zuomua Decoction is a classical Tibetan medicine for Chalong disease, but its mechanism is not clear. Therefore, in this paper we explored the multi-components, multi-targets and multi-channels mechanism of Zuomua Decoction in the treatment of hypertension based on network pharmacology and molecular docking technology. First of all, the chemical components of Zuomua Decoction were obtained in the retrieval of traditional Chinese medicine systems pharmacology database(TCMSP), China National Knowledge Infrastructure(CNKI) and Wanfang database. The potential targets of Zuomua Decoction were predicted by BATMAN-TCM database, and the targets of hypertension were obtained by using DisGeNET database. The intersection of these two targets set was taken to obtain the potential targets of Zuomua Decoction in the treatment of hypertension, and then the chemical compositions-targets network was constructed. Secondly, the intersection targets were imported into STRING database to obtain the interaction relationship of intersection targets, and the protein interaction network of Zuomua Decoction in the treatment of hypertension was constructed in Cytoscape. Topological, GO, and KEGG enrichment analysis were used to construct the key targets-signal pathways-biological processes network diagram and explore the mechanism of Zuomua Decoction in the treatment of hypertension. Finally, the key targets were selected to construct the pharmacodynamic identification models to verify the effect mode of Zomua Decoction in treating hypertension. The results showed that there were 61 chemical components and 90 potential targets in the compounds-targets network. We obtained 21 key targets, 154 signal pathways, and 382 biological processes in topological, GO, and KEGG enrichment analysis of the protein interaction network, and in the comprehensive analysis, it was found that Zuomua Decoction could reduce blood pressure by regulating renin angiotension aldosterone system, balancing the concentration of intracellular calcium and sodium ions and regulating vasoconstriction and relaxation. ACE, AGTR1, and ADRB2 were used as the carriers for molecular docking study on the components of Zuoma Decoction, and the results showed that the chemical components of Zuomua Decoction had a good binding activity with key targets. The purpose of this study is to provide ideas for the in-depth study of Zuoma Decoction in the treatment of hypertension, and provide scientific basis for its clinical rational application.
