Objective To assess the effect of rhein on diabetic nephropathy in rats with type 2 diabetes mellitus. Methods Diabetes was induced by high-lipids and high-sucrose diets (20% sucrose, 10% lard, 2.5% cholesterol, 1% cholic acid and 66.5 % regular chow, w/w) for 1 month and then intraperitoneal injection with 25 mg/kg streptozoticin(STZ) in female inbred Wistar rats. Rhein was continuously given 100 mg?kg-1?day-1 for 6 months 1 week after STZ injection in rhein-prevented group, and 1 month after STZ injection in rhein-treated group. Blood and urinary biochemistry and renal morphology were evaluated at divers times. Results Rhein ameliorated hypertriglyceridemia and hypercholesterolemia, but had few effect on the level of plasma glucose in both rhein-prevented group and rhein-treated group. Excretion of urinary protein reduced markedly and stable-state plasma glucose (SSPG) level decreased in both groups as compared with diabetic group. Examination of kidney sections from both rhein-prevented group and rhein-treated group showed that the structural lesions of glomeruli including mesangial expansion, diffuse glomerulosclersis and thickening of glomerular basement membrane, as well as artery injury such as arteriolar hyalinosis, atherosclerosis were markedly improved as compared with diabetic group. Morphometry of glomeruli from both rhein-prevented group and rhein-treated group showed that glomerular grow and mesangial hypertrophy occurred in diabetic group were ameliorated. The accumulation of fibronectin examined by immunostaining in glomeruli was reduced in both groups. Conclusion Therapeutic intervention with rhein can halt the progression of diabetic nephropathy and prevent the development of glomerulosclerosis and vascular injuries in this animal model of type 2 diabetes mellitus.

Objective To explore the clinical effect of ligament advanced reinforcement system ( LARS) artificial ligament reconstruc-tion of the anterior cruciate ligament ( ACL) in the operation. Methods Sixty patients with ACL injury in our hospital from September 2011 to May 2013 were randomly divided into LARS group and autologous hamstring tendon ( group ST/G) group with 30 cases in each group,the Lysholm score,IKDC score,the difference of clinical effect and bone tunnel of patients in two groups before treatment and at 3rd,6th,9th, 18th months after treatment were compared. Results The time of walking with crutch,ambulation and restore movement in LARS group were obviously shorter than those in ST/G group(P<0. 05). The Lysholm score,IKDC score,the difference of clinical effect and bone tunnel of patients in two groups after treatment were better than those before treatment(P<0. 05). The difference of Lysholm score and IKDC score be-tween two groups before operation was not significant (P>0. 05). The Lysholm score and IKDC score of LARS group at 3rd,6th,9th months after operation was higher than that of ST/G group,and at 18th months after operation,the difference of Lysholm score and IKDC score be-tween two groups was not significant (P>0. 05). At the last follow-up,the distribution effect of LARS group was higher than that of ST/G group (P<0. 05). The excellent and good rate of LARS group (93. 33%) was higher than that in ST/G group(76. 67%),but the difference was not significant (P>0. 05). There were 6 cases of patients with bone tunnel enlargement in LARS group,14 patients had bone tunnel en-largement in ST/G group. The bone tunnel enlargement rate was significantly higher than that of the LARS group (P<0. 05). Conclusion Ligament advanced reinforcement system of artificial ligament in anterior cruciate ligament reconstruction with autologous hamstring tendon re-construction can significantly speed up the recovery of the patients,and improve the postoperative curative effect and reduce the incidence of postoperative bone tunnel enlargement.

Background and purpose:Breast cancer is one of the most common carcinoma among female patients with high mortalities. Drug-resistance is the major reason that leads to chemotherapy failure in clinical practice. MCF-7/ADR is a multi-drug resistant cell line that was established on the basis of breast cancer cell line MCF-7. This research aimed to investigate the anti-apoptotic effect of c-fos in resistant breast cancer cell MCF-7/ADR, and to compare with its sensitive counterpart MCF-7.Methods:Doxorubicin with various concentrations was used to treat MCF-7 as well as its MDR- counterpart MCF-7/ADR. The growth inhibitory rate of MCF-7 and MCF-7/ADR wasdetermined by MTT assay. Additionally, RT-PCR was used to test the expression of P-gp and c-fos mRNA in MCF-7 and MCF-7/ADR; The expression of c-fos mRNA was detected by RT-PCR after 3 μmol doxorubicin treatment;We further established cell lines that stably interfered with c-fos, named MCF-7/ADR/si-fos-8B, MCF-7/ADR/si-fos-3D. Flow cytometry and MTT assay were used to investigate the apoptosis rate and inhibitory rate in these above cells under the treatment of 5-FU, CDDP or γ-radiation. At last, RT-PCR and Western blot analysis were used to detect the expression of bax, bcl-2, puma, p53.Results:The expression of c-fos and P-gp (MDR-1) was up-regulated in MCF-7/ADR, compared with its sensitive counterpart MCF-7. Additionally, the resistant fold of MCF-7/ADR to doxorubicin was nearly 40; The expression of c-fos was gradually up-regulated after 3 μmol doxorubicin treatment; The sensitivity to drugs (5-FU and CDDP) was increased after c-fos interference while the apoptosis rate was also increased after 5-FU, CDDP and γ-radiation treatment. RT-PCR and Western blot analysis indicated that up-regulation ofbax,puma,p53 after c-fos interference while the expression of bcl-2 was down-regulated.Conclusion:c-fos may act as an anti-apoptotic protein in resistant breast cancer cell line MCF-7/ADR by regulating the expression of apoptosis related proteins, and may play a vital role in the formation of multi-drug resistance phenotype.

Background: Endoscopic surgery of Western medicine has developed rapidly in treating ureteral calculi while traditional Chinese medicine (TCM) therapy also has its advantage, thus the integrated traditional Chinese and Western medicine therapy may have an even better efficacy in dealing with this problem. Objective: To observe the clinical effects of sequential therapy of Quantong Recipe, a compound traditional Chinese herbal medicine, combined with ureteroscopic laser lithotripsy on ureteral calculi. Design, setting, participants and interventions: A total of 151 patients with ureteral calculi (stone diameter of 3 to 21 mm) from Department of Urology, Yueyang Hospital of Integrated Traditional Chinese and Western Medicine, Shanghai University of Traditional Chinese Medicine were included, of which 106 patients with stone diameter of 3 to 10 mm were treated with Quantong Recipe for the first two weeks. Twenty patients with unexpelled stones and 45 patients with stone diameter of more than 10 mm were treated with ureteroscopic laser lithotripsy. The 65 patients except one open operation were divided into regular treatment group (32 cases) and regular treatment combined with Quantong Recipe group (32 cases) after lithotripsy. The efficacy was assessed after one week. Main outcome measures: Cure rate in the patients with stone diameter of less than 10 mm after two-week Quantong Recipe treatment was calculated, and clearance rate in the patients with residual stone for ureteroscopic laser lithotripsy after one-week Quantong Recipe treatment was also observed. Results: After taking Quantong Recipe for two weeks, the stones in 86 patients were completely discharged, and the stones in 6 patients were not completely discharged, but the unexpelled stones had moved down more than one segment of ureteral stenosis; the total response rate was 86.79% (92/106). The 64 patients with stones unexpelled or with stone diameter of more than 10 mm were treated with ureteroscopic laser lithotripsy, and the clearance rate of residual stone was 93.8% in regular treatment combined with Quantong Recipe group, and was 71.9% in regular treatment group, and there was a significant difference between the two groups (P<0.05). Conclusion: Sequential therapy of Quantong Recipe integrated with ureteroscopic laser lithotripsy demonstrates a significant advantage of integrated traditional Chinese and Western medicine therapy in treating ureteral calculi.
