Objective To study the effect of Tacrolimus on blood lipid after renal transplantation,and the relationship between C825T polymorphism in G protein beta 3 subunit (GNB3) gene and serum lipid levels.Method Eighty-one cases of recipients patients after renal transplantation were divided into two groups in terms of Tacrolimus concentration:normal blood concentration group (group A) and low blood concentration group (group B).The serum lipid levels at 1st,3rd,6th,and 12th month after renal transplantation were measured.Genotype was determined by the simple sequence-specific primer polymerase chain reaction (SSP-PCR).Result The percentage of patients with hypertriglyceride in group A was significantly higher than in group B during the one-year follow-up period.There was significant difference between the two groups in the serum triglyceride levels but no difference in the serum cholesterol levels.The 825C/T polymorphism in the GNB3 gene was not associated with hypertriglyceride in renal transplantations in Wenzhou.Conclusion The serum triglyceride levels in renal transplantations in Wenzhou was associated with the Tacrolimus concentration,and the incidence of hypertriglyceride is not associated with the 825C/T polymorphism in the GNB3 gene.

Objective To investigate the effect of the polymorphisms of multidrug resistance 1 (MDR1) C3435T and G2677T on Tacrolimus (Tac) individualized treatment and prognosis of grafts in the renal transplantation recipients (RTRs).Methods One hundred and twenty-seven RTRs who treated with Tac regimen and had a stable graft function were enrolled,and were divided into adjuvant treatment group and non-adjuvant treatment group according to whether given adjuvant drugs to raise Tac trough concentrations. MDR1 C3435T and G2677T SNPs were detected by using sequence specific primers PCR.Tac trough concentrations of whole blood were measured by using enzymelabeled immunosorbent assay.Tac concentration-to-dose ratio (C/D) standardized by body weight was compared according to the various genotypes and haplotypes of MDR1 C3435T and G2677TA SNPs.Results Adjuvant treatment group including 36 recipients had a higher frequency of C genotype of C3435T than un-adjuvant treatment group (68.05% vs 48.35%,P < 0.01 ). The frequency of G2677TA polymorphisms was of no significant difference between the two group recipients (P> 0.05).As to non-adjuvant treatment recipients,the mean Tac DD required and C/D were not significantly different among various polymorphisms of MDR1 G2677T/A and C3435T or various haplotypes (P>0.05).During A follow-up period of 4 years,13 recipients suffered graft dysfunction in which 84.6% (11/13) carried 3435C genotype (P>0.05).Conclusion The frequency of MDR1 C3435T polymorphisms in RTRs is high in the recipients given adjuvant treatment to raise Tac concentrations.Recipients with 3435C genotype were prone to graft dysfunction.

Objective To explore the factors related to the delayed graft function (DGF). Methods Clinical data of 150 recipients were collected and performed by Cox proportional hazards regression analysis . In addition, the glutathione S-transferase (GST) gene polymorphism of 172 donors and 157 healthy persons was analyzed by multiple PCR and SSP-PCR. Results DGF was observed in 24 patients among 150 recipients. Pretranplantation dialysis mode, PR A levels and recipient gender were uncorrelated with the incidence of DGF(P>0. 05). Urinary volume of the second 24 hours after transplantation was an independent predictor of DGF(RR=1. 002, P = 0. 001). The frequency of donor's null GSTM1 in DGF group was significantly higher than that in non-DGF group(P<0. 05). Conclusions Urinary volume of the second 24 hours after transplantation could be a predictor for DGF. The null GSTM1 in donor might be one of the factors related to the EGF.

Objective To investigate the association of genetic polymorphisms in glutathione S-transferases T1 (GSTrl), M1 (GSTM1) and P1 (GSTP1) with aristolochic acid nephropathy (AAN) of Chinese people in Wenzhou of China. Methods Fifty-nine patientswith AAN (AAN group) including 29 male and 30 female as well as 157 healthy ethnically matched controls (control group) including 93 male and 64 female were enrolled in this study. The genotypes of GSTT1, GSTMI and GSTP1 were determined by multiple PCR and confronting two-pair primers PCR (CTPP-PCR). Results The genotype frequencies of GSTP1 were in Hardy-Weinberg equilibrium. Compared with the healthy controls, the frequency of GSTT1 null genotype was significantly higher in the patients with AAN (66.1% vs 48.4%,P<0.05). Risk of A.AN for individuals with GSTT1 null genotype was 1.747 fold of those without GSTIl null genotype (95% CI=0.818-3.731). The frequency of GSTM1 null genotype, GSTP1 variant genotypes and GSTP1 G allele in the patients and in the controls were 40.7%, 28.8%, 16.1% and 47.8%, 31.8%, 17.5%, respectively, which were not significantly different. No significant differences were found in prevalence of GSTM1 and GSTP1 gene distribution between patients and controls. Conclusion GSTrl gene polymorphism appears to be associated with susceptibility to AAN in Southern China.
