Objective To study whether bifendate (BFD) can decrease blood concentration of cyclosporine A (CsA) in the patients subject to renal transplantation. Methods In the 106 cases undergoing renal transplantation treated with CsA, Pred and Aza, 65 were administrated with BFD as experimental group and the remaining 41 cases without BFD as control group. Blood concentrations of CsA, and biochemistry indexes for liver and renal function were determined. Results Blood concentrations of CsA in the experimental group went down by 26. 5 % as compared with those before taking BFD and had a significant decrease as compared with control group (P

Objective To explore the observation and nursing of the surgery of dysembryoplastic neuroepithelial tumors (DNT) in the function zone of brain.Methods A retrospective analysis of the clinic data of 5 patients receiving the surgery for the dysembryoplastic neuroepithelial tumors (DNT) in the function zone of brain was carried out,the clinical nursing experience was summarized.Results The EEG was re-examined 1 week after surgery.4 cases showed roughly normal EEG,one case with rare slow wave.The re-examined EEG 3 months after surgery suggested 3 cases were normal and 2 cases were almost normal.No epilepsia occurred after 6-month follow-up.Conclusions For DNT patients,microsurgical resection of the tumor is effective and enhancing the patients' perioperative observation and nursing has a significant meaning to increase the success of surgery,reduce complications,promote the rehabilitation of patients and improve the quality of life of patients.

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.

Objective To investigate if insulin can affect the expression of vascular endothelial growth factor (VEGF) in the retina of streptozotocin-induced diabetic rats. Methods A total of 60 male Sprague-Dawley rats were randomly divided into sodium citrate buffer control group (CIT-CON, n= 30) and STZ-induced diabetic group (STZ-DM, n=30). At the 16th week, 24 rats from CIT-CON group at random were randomly divided to group A (sodium citrate buffer control group, n = 12) and group B (sodium citrate buffer plus insulin group, n= 12). The remaining 6 rats from as CIT-CON group served as negative control. At the same time, 24 rats from STZ-DM group at random were randomly divided to group C (STZ-induced diabetic group, n= 12) and group D (STZ-induced diabetic plus insulin group, n= 12). The remaining 6 rats from STZ-DM group also served as negative control. 4 IU of insulin was injected subcutaneously to rats of group B and D. Immunohistochemistry, Western blot and Real-time polymerase chain reaction (RT-PCR) were used to measure the expression level of VEGF protein and mRNA respectively. RESULTS Insulin significantly increased the VEGF mRNA (7.71 ± 0.25 vs 5.36 ±0. 37, t test P< 0. 05) and protein expression (0. 4925 ± 0. 0122 vs 0. 4272 ± 0. 0110, t test P< 0. 05) in the retina of CIT-CON rats.However, in retina of STZ-DM rats, insulin had no effect on VEGF mRNA (8. 92±0. 27 vs 9. 05±0. 28, t test, P>0. 05) and protein expression (0. 5152±0. 0109 vs 0. 5099±0. 0100, t test P>0.05). Conclusions Insulin had no effect on VEGF expression in the retina of STZ-DM rats.

Objective To evaluate the anti-tumor activity and toxicity of FOLFIRI regimen in the treatment of patients with advanced colorectal cancer. Methods 22 patients with advanced colorectal cancer used Irinotecan combined with 5-Fu/CF regimen to chemotherapy. Regimen: CPT-11 150 mg/m2 iv drip d1, CF 200 mg/m2 iv drip 2 h d1, 2; 5-Fu 400 mg/m2 iv drip d1, 2; 5-Fu 600 mg/m2 iv drip 22 h d1, 2. It is repeated every 2 weeks, two times a course. Efficiency and toxicity was evaluated after 4-6 cycles. Results Forty four patients were evaluated the efficiency. Two patients achieved CR, 16 PR, response rate was 40.9 %; MST was 11.3 months. TTP was 6.5 months. The main toxicity was cholinergic syndrome and delayed diarrhea,myelosuppression. There were no deaths during treatment. Conclusion The effectiveness of FOLFIRI regimen was higher and side effects was minor in advanced colorectal cancer. It should be further used and studied.

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 evaluate the efficacy and safety of Fluvastatin vs. Xuezhikang for hyperlipidemia in patients after renal transplantation. METHODS: 56 hyperlipidemia patients after renal transplantation were enrolled: 32 were assigned to receive Fluvastatin (40～80 mg) po qd for 8 weeks and 24 to receive Xuezhikang (0.6 g) po bid for 8 weeks. Total cholesterol (TC),triglyceride (TG),low-density lipoprotein-cholesterol (LDL),high-density lipoprotein-cholesterol (HDL),liver function and renal function in two groups were measured before and after treatment. RESULTS: In Fluvastatin-treated group,the TC decreased from(7.39?1.98)mmol?L-1 to(5.62?0.93)mmol?L-1,LDL reduced from(3.68?1.13)mmol?L-1 to (2.86?0.83)mmol?L-1;in Xuezhikang-treated group,TC decreased from(6.82?1.29)mmol?L-1 to (5.56?1.19) mmol?L-1 and LDL decreased from (3.26?0.73) mmol?L-1 to (2.78?0.80) mmol?L-1,all showing significant differences as compared with before treatment(P 0.05). No obvious adverse effect was noted in either group during treatment. CONCLUSION: Both Fluvastatin and Xuezhikang are safe and effective for hyperlipidemia in patients after renal transplantation.

The aim of this paper was to investigate the effect of terpene penetration enhancers on membrane fluidity and membrane potential using HaCaT keratinocytes, and study the potential mechanisms of these terpene compounds using as natural transdermal penetration enhancer. Six terpene compounds, namely menthol, limonene, 1,8-cineole, menthone, terpinen-4-ol and pulegone, were chosen in this study on account of their good penetration-enhancement activities. The cytotoxicity of these terpene compounds was measured using an MTT assay. The fluorescence recovery after photobleaching (FRAP) technique was employed to measure the change of membrane fluidity of HaCaT cells. The flow cytometer was used to study the alteration of membrane fluidity of HaCaT cells, and investigate the effect of terpene compounds on intracellular Ca2+. It was found that 6 terpene compounds possessed low cytotoxicity in comparison to the well-established and standard penetration enhancer azone. Those terpene compounds could significantly enhance HaCaT cells membrane fluidity and decrease HaCaT cells membrane potentials. Meanwhile, after treated with various terpene compounds, the Ca2(+)-ATPase activity and intracellular Ca2+ of HaCaT cells was decreased significantly. Terpene penetration enhancers perhaps changed the membrane fluidity and potentials of HaCaT cells by altering the Ca2+ balance of the cell inside and outside, resulting in the low skin permeability to increase the drug transdermal absorption.
