Objective:To investigate the protective effect of Epigallocatechin-3-gallate (EGCG) on triptolide (TP)-induced immunological liver injuries, and explore the relevant mechanisms of action. Methods: A total of 40 female C57BL/6 mice were randomly divided into four groups:control group,EGCG group,TP group and TP+EGCG group. The ALT levels in serum was examined by Reitman Frankel method. The activity of hepatic MDA,SOD and GSH was examined by spectrophotometry. HE staining was used to observed the changes of the hepatic histopathology. The hepatic IL-17,IL-6 levels was examined by ELISA and the expression of hepatic TLR4 protein was examined by Western blot. Results:The results showed that serum alanine aminotransaminase ( ALT) levels of TP group were obviously elevated (P<0. 005,vs normal control group) and serum ALT levels were obviously reduced in EGCG treatment group(P<0. 005,vs normal TP group). There were no significantly differences between EGCG group and control group (P>0. 05). Meanwhile,EGCG could ameliorate hepatic pathological damage. Furthermore,in TP group,the activity of malondialdehyde ( MDA) ,the expression of Toll-like receptor 4 (TLR4) protein and the contentration of hepatic interleukin (IL)-17,IL-6 were higher than normal control group ( P<0. 005 ) . On the contrary, the activity of superoxide dismutase ( SOD ) and restored glutathione ( GSH ) were significantly lower than normal control group ( SOD, P<0. 05;GSH, P<0. 005 ) . In EGCG treatment group, the expression of TLR4 protein and the concentration of MDA,hepatic IL-17 and IL-6 were lower than TP group ( TLR4,P<0. 05;MDA,P<0. 005;IL-17,P<0. 005;IL-6,P<0. 005). On the contrary,SOD and GSH were significantly higher than TP group (SOD,P<0. 05;GSH,P<0. 005). Conclusion:This study suggests that EGCG possesses hepatoprotective effect against TP-induced immunological liver injury through its anti-inflammatory and anti-oxidant actions.

Objective To observe the protective effect of gradual ischemic postconditioning (IP) capable of improving reperfusion on reperfusion injury in patients with ST-segment elevation acute myocardial infarction (STEAMl) undergoing primary percutaneous coronary intervention (PPCI).Methods 102 in-patients with STEAMI undergoing PPCI in the Department of Cardiology in the First People's Hospital of Kunshan City Affiliated to Jiangsu University from February 2011 to August 2014 were enrolled in this study. They were divided into three groups by a random number table: IP group (32 cases), gradual IP group (30 cases) and routine reperfusion group (40 cases). In IP group, after the opening of the infarction related blood vessel, ischemic postconditioning within the first minute of arterial reperfusion was made through three episodes of 1 minute inflation and 1 minute pressure withdrawn of an angioplasty balloon, and then persistent reperfusion was carried out. In the gradual IP group, the patients received three times of gradual angioplasty balloon inflation and denation, 1 minute/1minute, 30 seconds/30 seconds and 15 seconds/15 seconds respectively, presenting the gradual change of IP time. In the routine reperfusion group, after the opening of blocked blood vessel, the patients underwent routine PCI to persistently recover the coronary artery blood supply. The changes of related lead ST segment regression (Sum-STR), incidence of reperfusion arrhythmia, corrected thrombolysis in myocardial infarction (TIMI) franle count (CTFC), peaks of MB isoenzyme of creatine kinase (CK-MB), left ventricular ejection fraction (LVEF) and frequency of adverse events in follow-up period were compared among the three groups.Results The baseline characteristics were comparable in three groups. The incidence of ventricular premature beats was significantly lower in gradual IP group than that in routine reperfusion group [30.0% (9/30) vs. 55.0% (22/40),P < 0.05], and although theincidence of ventricular premature beats was lower in IP group than that in routine reperfusion group [34.4% (11/32) vs. 55.0% (22/40)], no statistically significant difference was found (P > 0.05). The incidence of ventricular tachycardia was significantly lower in IP and gradual IP groups than that in routine reperfusion group [15.6% (5/32), 13.3% (4/30) vs. 40.0% (16/40), bothP < 0.05]. The incidences of ventricular fibrillation, bradyarrhythmia and sinus arrest were lower in IP group and gradual IP group than those in routine reperfusion group, but no statistically significant differences were found (allP > 0.05). In IP group and gradual IP group, the Sum-STR incidence, CTFC, CK-MB peaks were lower than those of routine reperfusion group [Sum-STR: (56.7±18.3)%, (57.3±21.5)% vs. (44.6±21.6)%; CTFC: 25.47±5.37, 24.46±6.41 vs. 31.62±7.56; CK-MB peaks (U/L): 126.3±78.5, 121.6±82.5 vs. 147.4±72.5; allP < 0.05], the effect of gradual IP group being the best among the three groups. The levels of LVEF were slightly higher in IP and gradual IP groups than the level in routine reperfusion group (0.507±0.042, 0.511±0.062 vs. 0.497±0.062), but no statistically significant difference was found (bothP > 0.05). In routine reperfusion group, one patient died because the ventricular fibrillation could not be corrected and another one died of no-reflow during operation. Each group had 1 patient died during the 4 weeks of follow-up after operation, in the routine reperfusion group, one died of refractory heart failure, and the cause of death of other two patients, one in IP group and another in gradual IP group, was considered due to subacute thrombosis in stent. Major bleeding events were not found in each group.Conclusion Gradual IP can ameliorate myocardial reperfusion injury more significantly in patients with STEAMI undergoing PPCI.

Objective To evaluate the urodynamic and functional characteristics of 26 patients who had underwent orthotopic contient globular ileal neobladder. Methods The clinical date of 26patients who underwent radical cystectomy were reviewed. The neobladder pressure, capacity, urethral pressure and urinary flow rate were collected at 3-12 months after operation. Results The neobladders average pressure was less than 15 cm H2O when the volume was 400 ml. The pressure was 22.4 cm H2O at 100% capacity. The mean pressure of contractions was less than 40 cm H2O. The mean filling pressure after operation was relative stable while the difference between 3 months and 6 months was statistically significant. The difference between 6 and 9 and 12 month showed no statistical significance. The mean post-void residual was 42 ml. A mean voiding flow rate of 19. 6 ml/s could be obtained by Valsalva. Conclusion The neobladder not only could offer adequate capacity at low pressures but also could give a satisfied continent.

The resident infection rate of schistosomiasis in Xinnong Village,Chuanxin Town,a national surveillance site of schistosomiasis.decreased to 0.14% in 2008.which suggested that the surveillance site reached the criteria for trammission control.

Objective To evaluate the clinical application of female orthotopic ileal neobladder.Methods Modified radical cysteetomy plus orthotopic ileal neobladder was performed on 19 female pa-tients with bladder cancer from June 1999 to January 2008.The mean age of the patients was 52(45-66) years,mean course of disease was 4.4 months (16 days-1.9 years).Of all the patients,there were 10 cases with grade 1,7 cases with grade 2 and 2 cases grade 3.According to the UICC stage system,5 patients were T1 stage,12 T2 and 2 T3a.All the patients received modified radical cystecto-my without resection of uterus and anterior vagina,meanwhile the nerves around urethra were protec-ted.0.8-1.2 cm proximal end of the urethra was excised and 30 cm distal ileum was used for the re-construction of the neobladder.Results Sixteen cases were followed up for 6-102 months,mean 71 months.Fifteen patients survived without disease recurrence,1 patient died of myocardial infarc-tion 17 months postoperation.The daytime and night continent rate was 100$,93% at 9 months postoperative.The average voiding volume of the 15 patients was 519.0 ml.The average residual vol-ume was 29.2 ml,and Qmax was 18.6 ml/s.The average filling and voiding pressure was 16.7 cm H2O and 53.0 cm H2O.Intravenous urography showed slight hydronephrosis in 1 case.Conclusion Female orthotopic ileal neobladder could be a good choice because of the continence,fewer complica-tions,lower pressure and enough bladder capacity.

Objective To understand the teachers′health status of one university in Chongqing to provide the basis for the healthcare of this group.Methods The teachers′health examination information in1 303 cases of physical healthy examination was retrospectively analyzed.The data were analyzed by the SPSS17.0 statistical software.Results The main detected diseases were conj unctivitis,fatty liver,cataract,refractive error,eyeground arteriosclerosis and hypertension.The top-5 health risk factors includ-ed dyslipidemia,overweight,hyperpiesia,increased uric acid and fasting blood glucose abnormality.The detection rates of conj uncti-vitis,fatty liver,eyeground arteriosclerosis,overweight,hyperpiesia,increased uric acid,fasting blood glucose abnormality examined in males were obviously higher than those in females(P<0.05),while which of cataracts,refractive errors,hypertension and dyslip-idimia were not relevant to gender(P>0.05).Apart from the increased uric acid(P=0.740),the morbidity and risk factors in dif-ferent ages were markedly different(P<0.01).The case rate of diabetes and hypertension was lower than the national average. Conclusion The eye health status of teachers in this university is not optimistic;there were many health risk factors.The health knowledge education of overweight,dyslipidemia,pathoglycemia and hyperpiesia should be carried out aiming at this group.

cry1Ah1, one of holo-type cry genes, cloned in this laboratory from Bacillus thuringiensis strain has been patented in China, and it encoded a protein with strong insecticidal activity against certain lepidopteran insect pests, such as Chilo suppressalis. cry1Ah1 gene is exhibiting good application prospects. In order to improve the expression level of cry1Ah1 gene in rice, and investigate the effect of codon usage preference of gene expression, we designed five different optimized schemes for cry1Ah1 insecticidal critical fragment in accordance with bias of rice codon, to improve G+C content, removed the shear signal and unstable factors. Optimized cry1Ah1 genes were transformed into Escherichia coli Rosetta (DE3) respectively, and 65 kDa polypeptides was expressed normally in inclusion body separately. All of these expressed polypeptides showed insecticidal activity against 2nd-instar larvae of Plutella xylostella and neonate of Chilo suppressalis. After transformation with modified cry1Ah1 genes into Var nippobare, the transgenic rice seedlings were detected by PCR, the positive rate containing target gene was more than 87%. Afterwards, the results of real-time RT-PCR and ELISA assay indicated that the highest expression level of five modified cry1Ah1 genes was that using the highest frequent codons. Average expression amount of Cry1Ah1 polypeptides was 0.104% of total soluble proteins from the positive transgenic rice.
