Objective:To investigate the effect of amlodipine atorvastatin on blood pressure and blood lipid in the patients with hy-pertension complicated with coronary heart disease (CHD). Methods: Totally 80 cases of outpatients with hypertension complicated with CHD were randomly divided into the observation group (40 cases) and the control group (40 cases). The control group was given amlodipine 10 mg,po,qn, and the observation group was given amlodipine and atorvastatin tablets 20 mg,po,gn, and the treatment course was 6 weeks. The changes of blood pressure and blood lipid in the two groups before and after the treatment were observed, and the clinical curative effect and adverse reactions were also studied. Results:Compared with those before the treatment, systolic blood pressure, diastolic blood pressure and blood fat in the two groups were all improved after the treatment, and the difference was statisti-cally significant (P<0.05), and the improvement in the observation group was more notable than that in the control group (P <0. 05). The total effective rate of the observation group was 92. 5%, which was higher than that in the control group(80. 0%, P<0. 05). The incidence of adverse reactions between the two groups showed no significant difference (P>0. 05). Conclusion: Amlo-dipine atorvastatin tablets can significantly improve blood pressure and blood lipid in the patients with hypertension complicated with CHD with promising clinical curative effect and few side effects, which is worthy of wide use in clinics.

BACKGROUND:Previous studies have found that the susceptibility genes of adiponectin gene and calpain 10 gene of type 2 diabetes are closely related with the incidence of diabetes in Chinese renal transplantation patients. So, are other susceptibility genes of type 2 diabetes also associated with posttransplantation diabetes mel itus? OBJECTIVE:To investigate the association between the zinc transporter solute carrier family 30 member 8 (SLC30A8) gene polymorphism and the posttransplantation diabetes mel itus. METHODS:A total of 97 patients with posttransplantation diabetes mel itus and 301 patents without posttransplantation diabetes mel itus (control group) were selected, and then the SLC30A8 gene rs13266634 genotype was detected with real-time PCR method. The association between gene polymorphism and posttransplantation diabetes mel itus was analyzed with Logistic regression test. RESULTS AND CONCLUSION:There were significant differences in al ele frequencies and genotype distributions of rs13266634 between the patients with and without posttransplantation diabetes mel itus (P<0.05). After adjustments of age, sex, body weight and body mass index, the incidence of posttransplantation diabetes mel itus of the CC genotype patients was 2.108 times to that of the TT genotype patients (odds ratio=2.108, 95%confidence interval:1.075-4.131, P=0.044);and the incidence of posttransplantation diabetes mel itus of the CC+CT genotype patients was 1.862 times to that of the TT genotype patients (odds ratio=1.862, 95%confidence interval:1.049-3.306, P=0.034). The results suggest that the C-al ele in rs13266634 of SLC30A8 gene is the independent risk factor of posttransplantation diabetes mel itus.

Purpose To investigate the expression of Wnt-1 and β-catenin protein in cervical squamous cell carcinomas ( CSCC) and their relationship with invasion and lymph node metastasis. Methods Expression of Wnt-1 and β-catenin protein were examined on immunohistochemistry containing 78 specimens of CSCC and 30 specimens of normal cervical tissues. Results The positive rates of Wnt-1 and β-catenin protein in normal cervical tissues were 20.0% and 10.0% respectively. The positive rates of Wnt-1 andβ-cate-nin protein in CSCC were 56.4%, and 74.4% respectively. There was a significant difference between the two groups (P<0.001). The positive rates of Wnt-1 andβ-catenin protein in 33 cases with lymph node metastasis of CSCC were 72.7% and 90.9% respective-ly. The positive rates of Wnt-1 andβ-catenin protein in 45 cases with no lymph node metastasis of CSCC were 44.4% and 62.2% re-spectively. The expression of Wnt-1 andβ-catenin protein was significantly related with grades of tumors and depth of invasion and FI-GO stages (P<0.05), and there was no significantly difference between the expression of Wnt-1 andβ-catenin protein and CSCC pa-tients age (P>0.05). Spearman analysis showed that the expression of Wnt-1 protein was positive related to the expression ofβ-cate-nin protein (rs =0.490, P<0.001). Conclusion The abnormal expression of Wnt-1 and β-catenin may be involved in initiation, development, invasion, and metastasis of CSCC, and it is suggested that Wnt-1 and β-catenin be considered as potential markers for invasion, metastasis, and prognosis.

Objective:To study the effect of cyclosporin A based triple immunosuppressive therapy on the plasma glucose in renal transplant recipients.Method:680 renal transplant recipients treated with cyclosporine A combined with prednisone and mycophenolate mofefil from Jan.1996 to May 2007 were analysed.Result:The morbidities of impaired fast- ing glucose,impaired glucose tolerance and post-transplantation diabetes mellitus (PTDM) were 3.97%,5.15% and 8.09%,respectively.The daily doses and concentrations of CsA and the daily doses of prednisone in the impaired glucose tolerance group and PTDM group were significantly higher than those in the normal plasma glucose group.Conclusion:The daily doses and concentrations of CsA and the daily doses of prednisone were closely related to the impaired glucose toler- ance and PTDM of renal transplant recipients.

Aim To investigate effects of berberine (Ber) on the transport of P-gp substrates including cyclosporine A (CsA) and digoxin across Caco-2 and L-MDR cell monolayers. Methods Permeability coefficients and transport rates of digoxin and CsA across Caco-2 and L-MDR1 monolayers were measured in the presence of Ber(50 ?mol?L-1~5 mmol?L-1). Results The inhibition studies for digoxin transport showed a dose-dependent decrease in basal-to-apical direction across Caco-2 and L-MDR1 monolayers in the presence of Ber (50 ?mol?L-1~5 mmol?L-1). Both a dose-dependent decrease in basal-to-apical direction and an increase in apical-to-basal direction were observed for CsA transport across Caco-2 monolayers with different concentrations of Ber. The IC50 values calculated for Ber-induced inhibition of digoxin transport are 1.44 mmol?L-1 in Caco-2 cells and 1.24 mmol?L-1 in L-MDR1 cells, respectively. The IC50 value for Ber-induced inhibition of CsA transport is 607 ?mol?L-1 in Caco-2 cells. Conclusion It was suggested that the inhibition and saturation of P-gp transport activity might be involved in interactions between Ber and CsA.

Objective To investigate the expression of Bmi-1,Mdm2 and Ki-67 in extrahepatic biliary duct carcinoma and to evaluate their clinical significance. Methods The expression of Bmi-1.Mdm2 and Ki-67 was detected in 10 normal extrahepatic biliary duct tissue and 30 cases of extrahepatic billary duct carcinoma with immunohistochemic0al staining and the their clinical significance were analyzed. Results No POsitlVe Bmi-1 expression was found in 10 normal extrahepatie biliary duct cages, while 18 of 30 extrahepatic biliary duct carcinoma cases showed positive Bim-1 expression.The expression of Bmi-I in extrahepatic biliary duct carcinoma(60.0%)was statistically higher than that in normal extrahepatie biliary duct(P<0.05).The positive expression rate of Mdm2 in extrahepatic biliary duct carcinoma was significantly higher than that in normal extrahepatic biliary duct (56.7%vs 20.0%,P<0.05).The cases of extrahepatic biliary duct carcinoma with Ki-67 proliferation index higher than 5%reached 60.0%,while the Ki-67 index was all lower than 1%in 10 normal extrahepatic biliary duct tissue, suggesting the higher proliferating activity of extrahepatic biliary duct carcinoma.No differences were found in the expressions of Bmi-1,Mdm2 and Ki-67 among extrahepatic biliary duct carcinoma cases with different clinical pathological features. Conclusion The results indicate that the expression of Bmi-1 and Mdm2 up-regulation may play an important role in carcinogenesis of extrahepatic biliary duct caroinoma. No clinical significances of the expressions of Bmi-1,Mdm2 and Ki-67 are found in extrahepatic biliary duct carcinomas.
