Objective:To investigate the correlation of ABCB1 polymorphisms and the synergistic effect of Wuzhi capsules on ta-crolimus. Methods:The ABCB11236C>T(rs1128503), ABCB12677G>T/A(rs2032582) and ABCB13435C>T(rs1045642) genotypes were determined by restriction fragment length polymorphism ( RFLP) analysis. The whole blood levels of tacrolimus in renal transplant recipients were measured by chemiluminescent microparticle immunoassay. Analysis of covariance ( ANCOVA) was per-formed to determine the difference of tacrolimus C0/D among the various groups. Results: Whether co-administeration of Wuzhi cap-sules and tacrolimus or not, tacrolimus C0/D of ABCB11236C>T, ABCB12677G>T/A and ABCB13435C>T genotype and haplo-type was without significant difference. Conclusion:When combined with Wuzhi capsules, ABCB11236C>T, ABCB12677G>T/A and ABCB13435C>T mutation is not associated with tacrolimus C0/D.

Objective To evaluate the effects of adenovirus-thediated PTEN gene transfer on growth and invasion of H22 cells in vitro. Methods H22 cells were tnmsfected with Ad-PTEN and Ad-PTENG-129R it vitro, The mRNA expressions of PTEN were detected with RT-PCR. Cell viability was determined by MTT assay. Invasion of H22 in vitro was observed using Boyden chamber. Results Gene and protein expressions of PTEN were shown to be up-regulated when H22 was transfected with Ad-PTEN. MTT assay showed that the group transfected with Ad-PTEN had much lower cell viability than other groups (P<0.05) . The number of 1422 invasion cells in the group of Ad-PTEN was (15.64±3.27) %, which was lower than the number in other groups (P<0.05). Conclusion These results imply that the number of H22 invasion cells was significantly decreased after infected with Ad-PTEN in vitro.

Objective To investigate the protective effects of endotoxin precondition on hepatic tissue in rats with endotoxemia.Method The models of rats with acute endotoxemia were produced by injecting LPS directly.Seventy-two male wistar rats were randomly divided into three groups:saline control group(N,n=24),lipopolysaccharide (LPS)-treated group(L,n=24),LPS pretreated group(P,n=24).Each group was divid-ed into four subgroups:saline control and lipopolysaccharide (LPS)-treated 2 h,4 h,6 h,12 h groups and LPS-pretreated 2 h,4 h,6 h,12 h groups.Rats in group P were first administered with introperitoneal injection of 0.25 mg/kg LPS,and after 24 hours,the rats were injected with 0.5 mg/kg LPS.Rats in group N and group L received with an equivalent amount of saline.After 72 hours,rats in group L and group P were intravenonsly injected with 10 mg/kg LPS,and rats in group N received with an equivalent amount of saline.Six rats were killed at 2,4,6 and 12 hours after injection of LPS in group L and P.The hvers were removed for detecting Toll like receptor-4 (TLR-4),nuclear factor-кB(NF-кB),tumor Necrosis Factor-apha(TNF-α)and malondialdehyde(MDA).The blood was drawn for detecting Alamine aminotmnsferose (ALT) and Aspartate aminotransferose (AST).The patho-logical changes of liver were also examined.Software SPSS13.0 was utilized to do ANOVA for statistical analysis.Results The rats exposed to LPS alone demonstrated an increase in TLR-4.NF-кB and TNF-α activity of the liver tissue.Incontrast.the rats exporsed 10 LPS prelreatment exhibited a significant decrease in TLT-4,NF-кB and TNF-α activity.The contents of TLR-4,NF-кB and TNF-α of LPS-treated 4 h groupwere,(38.76±0.67),170.82 ±31.40),293.16±49.49)and(6.263±0.351),significantly higher than those of the saline control group.The administration of endotoxin pretreatment reduced the indexes to(22.35±1.35),(135.55±26.44)and(234.23±44.96),respectively(P＜0.05).Conclusions TLR-4,NF-кB and TNF-α take part in the progress of hepatic injury in rats with endotoxemia.Endotoxin pretreatment can eliminate hepatic injury and protect the hepatic tissue by downmgulating the levels of TLR-4.NF-кB and TNF-α.

Objective:To explore value of plasma N terminal pro B type natriuretic peptide (NT-proBNP)assessing prognosis of patients With diastolic heart failure (DHF)complicated type 2 diabetes mellitus (T2DM).Methods:The folloW-up data of 206 inpatients With DHF and T2DM from our hospital Were retrospectively analyzed.Ac-cording outcome,they Were divided into no event group (n=108)and event group [n=98,With major adverse car-diovascular events (MACE)occurred].Levels of NT-proBNP,glycosylated hemoglobin (HbA1c),total cholesterol (TC)and loW density lipoprotein cholesterol (LDL-C),left ventricular end-diastolic dimension (LVEDd),left ventricular peak early diastolic velocity/peak late diastolic velocity (E/A)and left ventricular ejection fraction (LVEF)during admission Were measured and compared betWeen tWo groups. Results:Compared With no event group,there Were significant increase in NT-proBNP level and LVEDd,and significant decrease in LVEF and E/A in event group (P<0.05 all).Single factor linear analysis indicated that NT-proBNP,HbA1c,LVEDd and E/A Were positively correlated With MACE incidence rate (r=0.075~0.091,P<0.05 all).Mutivariate Logistic regres-sion analysis indicated that NT-proBNP Was an independent predictor for MACE (OR=1.003,P=0.009).Areaunder recieve operating characteristic curve (ROC)Was 0.803 for NT-proBNP predicting mortality of patients during admission (P <0.05),and survival rate of patientsWith plasma NT-proBNP≤4010pg/mlWas significantly higher than that of patients With NT-proBNP>4010 pg/ml (OR=5.028,P <0.05).Conclusion:Plasma NT-proBNP can independently predict prognosis of patients With diastolic heart failure complicated type 2 diabetes mellitus.

Objective To evaluate the quality of life for tuberculosis patients after anterior debridement, autograft bone fusion and anterolateral fixation operation. Methods 17 cases of thoracolumbar spinal tuberculosis were treated surgically from January 2008 to March 2011. All the cases underwent anterior debridement, autograft bone fusion and anterolateral fixation operation. MOS health survey 36-item Short Form (SF-36), Japanese Orthopaedic Association Scores (JOA) and Visual Analogue Scale (VAS) were used to evaluate the quality of life, spine function and pain symptom before and 1 and 6 months after surgery.

OBJECTIVE:To investigate the association of synergistic effects of Wuzhi capsules on tacrolimus with CYP3A5*3 (6986A>G,rs776746) gene polymorphisms. METHODS:One hundred and severty patients underwent renal transplantation receiving tacrolimus maintenance therapy after surgery were selected from our hospital during Jan. 1997-Dec. 2015,and then divided into Wuzhi capsules(+)group(74 cases)and Wuzhi capsules(-)group(96 cases)according to the use of Wuzhi capsules. Both groups received tacrolimus+mycophenolate mofetil+prednisone;Wuzhi capsules (+)group was additionally given Wuzhi capsules,one capsule each time,bid,for more than 12 months. Trough concentration of tacrolimus was detected by CMIA 0,1,3,6,12 months after medica-tion,and the blood concentrations(C0/D)were calculated at different time points after correcting daily dose. CYP3A5*3 gene polymor-phisms was detected by PCR-RFLP. The association of C0/D value with gene polymorphism was investigated by analysis of covariance. RESULTS:Among 170 patients,there were 65 cases of CYP3A5 GG genotype,83 cases of AG genotype and 22 cases of AA geno-type;genotype frequencies were 38.2%,48.8% and 12.9%,which was in line with Hardy-Weinberg balance (P>0.05). There was statistical significance in the distribution frequencies of GG,AG+AA genotype between Wuzhi capsules(+)group and Wuzhi capsules (-)group (P<0.05). After 1 month of medication,C0/D of tacrolimus in GG genotype was significantly higher in Wuzhi capsules (+)group than in Wuzhi capsules(-)group. After 1,3,6,12 months of medication,C0/D of tacrolimus in AG+AA genotype was sig-nificantly higher in Wuzhi capsules(+)group than in Wuzhi capsules(-)group,with statistical significance(P<0.05). There was no statistical significance in C0/D of tacrolimus in GG genotype between 2 groups after 3,6,12 months of treatment(P>0.05). CON-CLUSIONS:Wuzhi capsules can increase C0/D of tacrolimus in CYP3A5*3 AG+AA genotype,but have no significant effect on C0/D of tacrolimus in GG genotype;CYP3A5*3 genotype should be considered when using Wuzhi capsules as synergist of tacrolimus.

Objective To investigate the correlation of the 1896 and 1899 mutations of hepatitis B virus (HBV)with the conversion of e antigen in serum and the progression of the disease. Methods 238 serum samples from the patients with HBsAg positive for over six months and HBV-DNA copy number > 5.0 × 102 IU/mL were collected,and the sequence analysis was used to analyze the nucleotide sequences of the 1896 and 1899 sites in the pre-C region of HBV. At the same time,the relevant clinical data and the expressions of HBeAg were collected,followed by Spearman correlation analysis and chi square test with SPSS 20.0. Results Both 1896 and 1899 sites in the pre-C region of HBV were mutated,and the base G was A,which was closely related to the expression of e antigen(P<0.05). Both G1896A and G1899A promoted the e antigen serological conversion ,and the e antigen serological conversion of G1899A was higher than that of G1896A. G1899A was associated with HBV related disease progression (correlation coefficient 0.280,P < 0.05),especially with the incurrence of HCC. Conclusions G1896A and G1899A in the pre-C region of HBV can promote the serological conversion of e antigen.
