Objective To investigate the effects of MG132 on diabetic nephropathy (DN) rats induced with streptozocin. Methods Seventy-two male SD rats were randomly divided into three groups: normal control group (NC, n=24), DN group (n=24) and DN treated with MG132 group (DN+MG132, n=24). At the end of 4, 8 and 12 weeks, 24 hour urinary protein excretion rate (UPER) was detected. Morphology of kidney was examined by special staining of periodic acid-schiff (PAS). Renal 26S proteasome activity was determined by quantifying the hydrolysis of S-LLVY-AMC in a fluorescence reader. Urinary malondialdehyde (MDA) level and renal SOD and GSH-PX activity were detected by commercial kits. Renal SOD, GSH-PX and p47phox mRNA expressions were determined by real-time fluorescence PCR. Renal p47phox protein expression wasdetermined by Western blotting. Results Compared with NC group, the DN group showed a significant increased of UPER at week 4, 8, 12 (all P<0.05), of mesangium proliferation and mesangial matrix expansion at week 12. In DN+MG132 group, UPER was significantly decreased compared with DN group at the end of 4, 8 and 12 weeks (P<0.05, respectively), and the glomeruler pathological alteration induced by diabetes was attenuated. Increased renal 26S proteasome activity in DN rats was significantly inhibited after MC132 administration (P<0.05). Moreover, renal p47phox mRNA expression in DN group was 155%, 149% and 120% more than those in NC group at 3 time points (all P<0.05), and so was the renal p47phox protein expression, 139%, 152% and 186% more (all P<0.05). Urinary MDA levels in DN group were 1.95-, 2.04-and 2.62-folds more than those in NC group (all P<0.05). In addition, compared with NC group at 3 time points, in DN group, renal SOD activity was decreased by 23.09%, 33.59% and 53.31% (all P<0.05); renal GSH-PX activity was decreased by 28.57%, 33.06% and 48.76% (all P< 0.05); renal SOD mRNA was decreased by 38.09%, 61.44% and 76.53% (all P<0.05); renal GSH-PX mRNA group was decreased by 29.16%, 37.26% and 62.40% (all P<0.05). Compared with DN group, renal p47phox mRNA and protein expression, and urinary MDA levels were significantly lower in DN+MG132 group (all P<0.05); renal SOD and GSH-PX activity as well as mRNA expression were significantly increased in DN+MG132 group (all P<0.05). Conclusions MG132 treatment can provide renoprotection for DN rats effectively maybe through enhancing renal anti-oxidative ability.

Objective To investigate the effect of 4-phenylbutyric acid(4-PBA)on the renal pathogenesis of rats with streptozotocin-induced diabetes and its mechanism. Methods Fifty-four male SD rats were randomly divided into three groups:normal control group(NC group,n=18),diabetic nephropathy group(DN group,n=18),diabetic nephropathy plus 4-PBA treatment group(4-PBA group,n=18).At the end of 4,8 and 12 weeks,index of kidney weight/body weight ratio(KI)were measured and calculated.Serum creatinine (Scr),blood urea nitrogen(BUN),urinary MDA levels,urinary SOD activity,and 24 hour urinary protein excretion ram(UAER)were detected by HITACHI automatically.Morphology of kidney wag examined by special staining of periodic acid-schitt (PAS).The p47phox and nitrotyrosine (NT) expression in kidney were determined by real-time fluorescence PCR and Western blotting. Results Compared with the NC group, the DN group rats showed a significant increase of KI(P<0.05), UAER(mg/24 h) (4.92±0.70 vs 0.26±0.07, 5.29±0.83 vs 0.28±0.08, 5.54±0.81 vs 0.29±0.04,respectively, P<0.05]for indicated time, mesangial cells proliferation and mesangial matrix expansion at 12 week. However,4-PBA treatment could significantly inhibit the increase of KI (P<0.05), decrease UAER (mg/24 h) (3.71±0.37, 3.47±0.36, 3.28±0.40, respectively, P<0.05]for indicated time, and prevent the glomeruler pathological alteration induced by diabetes. Moreover, the mRNA expression of p47phox in the kidney of DN group was 154.72%, 148.60% and 91.95% more than that of NC group (all P<0.05) for indicated time. The protein expression of p47phox was 118.00%, 140.10% and 177.82% more than that of NC group (all P<0.05), and the protein expression of NT was 45.29%,59.13% and 89.28% more than that of NC group (all P<0.05). In addition, urinary MDA levels in DN group were 2.05-, 2.26- and 2.43- folds of NC group, and urinary SOD activities were decreased by 64.78%, 71.29% and 79.32% of NC group. Compared with the DN group, the mRNA and protein expression of p47phox, and protein expression of NT in 4-PBA group were decreased markedly (all P<0.05) at the end of 8 and 12 weeks. The urinary MDA level was decreased, and the urinary SOD activity was increased significantly in rats with diabetes after 4-PBA treatment for indicated time (all P<0.05). Conclusion 4-PBA treatment can significantly inhibit the renal pathogenesis of rats with diabetes through inhibition of oxidative stress.

Objective To investigate the effects of output power,action time and radiofrequency(RF) needle on the cool-tip radiofrequency ablation(RFA) by experimental tools and to determine the value of ultrasonography in size evaluation of RFA zone.Methods The cool-tip RFA to fresh calf liver were monitored by ultrasound.The experiments by single electrode needle were performed with different combination of output power (80 W,120 W) and time (5 min,8 min,10 min).The cluster needle was used for assessment at 5 min with different output power(80 W,120 W).After the end of trial,the longitudinal specimens were cut open.The view and size of the ablation zone were recorded with naked eyes.The pathological changes displayed by optical microscope were recorded as well.Results The measurement of ablation zone with naked eyes showed with the ablation zone expanded with time in 80 W-power cases,but the pace of expansion slowed down,but in 120 W-power cases,expansion of the ablation zone was not obvious; the ablation zone in 120 W-power was bigger than that in 80 W-power at 5 min,their difference decreased with time,and the ablation zones were similar at 10 min.The cluster needle can produce ablation zone with lesser aspect ratio than that of single electrode needle,consequently similar to circle.Ultrasonic measurement of the ablation zone had real discrepancy.Most of longitudinal diameters were greater than the real ones,while in large ablation lesions,vertical diameters were often less than the real ones.Under optical microscope,no change could be found in shape and structure of the cells in ablation zone.Conclusion The output power and performing time have impact on ablation.The high-power output increased heat production as well as reduction of heat conduction.Compared with single electrode needle,the cluster needle produced ablation zone closer to real hepatic tumor,thus has more reliable effect to small hepatocellular carcinoma with diameter around 2 cm.The ultrasond has a great significance in RFA guidance,but it could not accurately define the border of ablation zone.

Objective: To examine the alteration of pathologic structure and endogenous hydrogen sulfide pathway in rats with pulmonary hypertension induced by high pulmonary blood flow. Methods: Sixteen SD rats were randomly divided into shunting group and control group. An 11 week aortocaval shunting was produced in rats of shunting group, and pulmonary artery mean pressure (mPAP) was evaluated using right cardiac catheterization. The ratios of right ventricular mass to body weight (RV/BW) and right ventricular mass to left ventricular plus septal mass[RV/(LV+S)] were also detected. Pulmonary vascular micro and ultra structures were examined. Meanwhile the concentration of plasma hydrogen sulfide (H 2S) was measured by spectrophotography. The gene expression of cystathionine ? lyase (CSE)was detected by in situ hybridization, and the activity of CSE in lung tissues was measured by H 2S production according to chemical analysis. Results: After 11 weeks of aortocaval shunting, pulmonary artery mean pressure was significantly increased. Muscularization of small pulmonary vessels and relative medial thickness of pulmonary arteries were obviously increased in shunting rats compared with controls. Ultrastructure of intrapulmonary arteries changed obviously in shunting rats. Meanwhile, plasma H 2S concentration was decreased and the activity of CSE (according to H 2S production) in lung tissues decreased in shunting rats. CSEmRNA expression by pulmonary arteries was significantly suppressed. Conclusion: Pulmonary vascular structural remodeling is the important pathologic basis for pulmonary hypertension induced by high pulmonary blood flow. The down regula tion of endogenous H 2S pathway might play an im portant role in the development of high pulmonary blood flow induced pulmonary hypertension.
