ObjectiveTo evaluate the clinical efficacy and safty of combined treatment telmisartan plus simvastatin on early diabetic nephropathy. Methods46 patients with early diabetic nephropathy were randomly divided into two groups. Control group ( n ＝ 23 ) received regular insulin therapy, captopril l0mg tid. Study group received telmisartan 80mg qd plus simvastatin 20mg qd on the basis of control group therapy. All patients received 16 weeks treatment. The clinical parameters were measured before and after therapy. ResultsAfter 16 weeks treatment,the urine MAU in both study group and control group were significantly decreased( all P ＜0. 01 ) ,however,the urine MAU in telmisartan plus simvastatin combination group decreased significantly than control group( P ＜ 0. 01 ). Improvement of lipid level in the study group better than the control group( P ＜0. 01 ). Kidney function,fasting blood glucose levels and HbAlc had no significant changes before and after treatment. ConclusionTelmisartan plus simvastatin combined treatment was better than the traditional therapy,which can delay the development of early diabetic nephropathy.

Objective To explore the role of type 1 plasminogen activator inhibitor (PAI-1 ) in mediating renal tubulointerstitial injury of patients with IgA nephropathy. Methods The mRNA and protein production of PAI-l in renal tubulointerstitium were defected using in stiu hybridization and immunohistochemistry. Detections of antigens of ?-smooth muscle actin(?-SMA) and proliferating cell nucleus antigen (PCNA) were also performed. Results PAI-l was normally expressed in the walls of vessels and distal tubules, but significantly increased in lesions of IgA nephropathy, including crescents, Bowman capsules and tubulointerstitial infiltrating cells. There was lithe expression of PAl-1 in the glomerular capillary tufts. The renal expression of PAI-l was significantly correlated with serum creatinine (P

Objective To investigate the effect of infrasound on the growth of bone marrow mescenchymal stem cells (BMSCs) and seek the most reasonable duration for using infrasound. Methods The primary BMSCs were obtained from Sprague-Dawley rats through whole bone marrow adherent cultivation.The cells of passage 3 were divided into trial groups treated with infrasound for 10 min,30 min or 60 min,and control groups which were not treated with infrasound but exposed to air for the same durations.The vitality of cell proliferation was measured using the CCK8 method.Apoptosis and the cell cycle were analysed with flow cytometry (FACS). Results After cultivation for 72 h,the optical density (OD) values for BMSCs treated with infrasound for 10 min,30 min and 60 min were 1.480 ± 0.030,1.348 ± 0.030,1.493 ± 0.030 respectively and after 96 h they were 1.774 ± 0.030,1.731 ± 0.030 and 1.833 ± 0.030.All of which were significantly greater than in the control groups ( 1.479 ± 0.030,1.267 ±0.030 and 1.227 ± 0.030 after 72 h and 1.567 ± 0.030,1.563 ± 0.030 and 1.632 ± 0.030 after 96 h).With the extension of the treatment duration,the OD values of the BMSCs increased or increased after decreasing,and the OD value for BMSCs treated with infrasound for 60 min was the highest.The FACS results indicated no effect of infrasound on apoptosis of BMSCs when the treatment duration was 30 min,but that cell apoptosis could be inhibited when the treatment duration was 10 min or 60 min.The early phase apoptosis rates were 1.07％ ± 0.12％ and 0.97％ ±0.21％ in the trial groups treated for 10 min and 60 min respectively,and 1.43％ ± 0.06％ and 3.33％ ± 0.15％ in the respective control groups,a highly significant difference.The results of cell cycle analysis showed infrasound could disturb the cell division of BMSCs significantly when the treatment duration was less than 30 min,but there was no significant effect when the treatment duration was 60 min. Conclusions Infrasound can promote cell proliferation and disturb cell division,but it did not cause apoptosis of BMSCs.When the treatment duration was 60 min,cell proliferation improved steadily,the apoptosis rate decreased,and the cell cycle did not change.So 60 min is the most reasonable treatment duration for infrasound.

Objective To evaluate clinical effects of laparoscopy in acute abdominal emergency. Methods A retrospective analysis was made on clinical date of 146 cases of acute abdominal emergency from January 2001 to August 2005,including 86 cases of acute cholecystitis,45 cases of acute appendicitis,6 cases of closed abdominal trauma,5 cases of perforation of gastroduodenal ulcer,3 cases of pyosalpinx,and 1 case of adhesive intestinal obstruction. Results Out of the 146 cases,134 cases(91.8%) were successfully diagnosed and treated under laparcoscope,including 7 cases which could not be confirmatively diagnosed preoperatively.Conversions to open surgery were required in 12 cases(8.2%).No complications or fatal cases were noted.(Conclusions Laparoscopic) technique is safe,reliable,and micro-invasive in the diagnosis and treatment of acute abdominal emergency.
