Aim To explore the therapeutic effects of 3′-daidzein sulfonate sodium(DSS) on isolated myocardial ischemia/reperfusion injury and the relation of its mechanism to anti-oxidation.Methods An isolated rat myocardial ischemia/reperfusion injury was made,and the injury was treated with DSS.Following the treatment,the coronary blood flow levels,left ventricular systolic pressure,and activities of enzymes(LDH,SOD,GSH-Px) were measured.Results After treatment,the isolated myocardial tissue showed an increase in the volume of perfusion and an increase in the enzymatic activities of LDH,SOD,GSH-Px in the myocardial tissue.Conclusion DSS has a therapeutic effect on isolated myocardial ischemia/reperfusion injury because it enhances anti-oxidative activity in myocardial tissue.

Objective To explore the influence of the lentiviral vectors-mediated mouse genetic engineering regulatory T cells (Treg) infused after allogeneic bone marrow transplantation (alloBMT) on graft-versus-host disease (GVHD) and graft-versus-leukemia (GVL) effect in mice.Methods Lentivirus-mediated expression of Forkhead box P3 (Foxp3) transformed CD4 + CD25- T cells from Balb/c mice into engineered Tregs in vitro. An allo-BMT model of Balb/c→C57BL/6 mice was established. The recipients were given lethal X-ray total body irradiation before transplantation.Mice were randomly assigned into five groups and each group contained 10 recipients: (1) The recipients in radiation group were injected with 0.2 ml RPMI 1640; (2) The recipients in leukemia control group were injected with 5 × 106 donor bone marrow cells and 500 mouse T-cell leukemia/lymphoma cells (EL4 cells); (3) The recipients in transplantation control group were injected with 5 × 106 donor bone marrow cells and 5 × 106 splenocytes plus 500 EL4 cells; (4) The recipients in engineering Treg group were injected with 5 × 106 donor bone marrow cells, 5 × 106 splenocytes and 500 EL4 cells plus 5 × 106 genetic engineering Treg; (5) The recipients in empty vector control group were injected with 5 × 106 donor bone marrow cells, 5 × 106 splenocytes and 500 EL4 cells plus 5 × 106 empty vector-transduced CD4+ CD25- T cells. Survival time, clinical GVHD score or histopathological analysis (skin, liver and small intestine) were observed after allo-BMT. Chimerism of bone marrow cells from recipients survived for 60 days after transplantation was measured. Results The mean survival time in radiation group, leukemia control group, transplantation control group,engineering Treg group and empty vector control group was ( 10. 3 ± 1.5), (20. 7 ± 1.9), (26. 0 ±4.3), (49. 0 ± 17. 7) and (24. 4 ± 4. 1 ) days respectively. The survival time in engineering Treg group was significantly prolonged as compared with other groups as judged by the log-rank test (P＜0. 05).Histopathological analysis in several target organs (skin, liver and small intestine) confirmed the presence of severe GVHD in transplantation control group and empty vector control group. No histological signs of GVHD or leukemia were observed in recipients in engineering Treg group and clinical GVHD scores in this group were significantly decreased as compared with transplantation control group and empty vector control group. Conclusion Co-injection of genetic engineering Treg can efficiently prevent recipients from lethal GVHD without affecting GVL activity during allo-BMT in mice.

Background:A recent perspective European study has shown that Chronic Liver Failure-Consortium Organ Failure score(CLIF-C OFs)is an effective diagnostic criteria for acute-on-chronic liver failure(ACLF)in alcoholic or hepatitis C virus patients with acute decompensation(AD). Aims:To assess the efficacy of CLIF-C OFs for distinguishing ACLF in non-hepatitis B virus(HBV)-related chronic liver disease patients with AD. Methods:A total of 274 consecutive non-HBV-related chronic liver disease patients with AD from Jan. 2005 to Dec. 2010 at Shanghai Ren Ji Hospital were enrolled. Patients were divided into three groups:ACLF at admission,ACLF developed within 28-day and non-ACLF according to CLIF-C OFs criteria. Clinical and biochemistry characteristics,severity of the disease and 28-day and 90-day mortality data between ACLF and non-ACLF groups were analyzed. Results:Of the patients assessed,40 had ACLF at admission,27 had ACLF developed within 28-day,207 remained not having ACLF. Patients in ACLF group had higher TB,Cr,INR,ALT,AST,ALB,WBC,score of Child-Pugh,CTP,MELD,MELD-Na than non-ACLF patients(P <0. 05),and were younger in age(P < 0. 01). Incidences of hepatic,renal,cerebral,coagulation,circulation and lung failure,28-day mortality,90-day mortality were significantly higher in ACLF group than in non-ACLF patients( P <0. 01). However,no significant differences were seen in the characteristics mentioned above between ACLF at admission group and ACLF developed at 28-day group(P > 0. 05). TB level at admission and infection occurred within 28-day were the risk factors for developing ACLF(P < 0. 05). Conclusions:ACLF constitutes a more severe subgroup in non-HBV-related chronic liver disease patients with AD,and CLIF-C OFs could help to distinguish ACLF patients out from non-HBV-related chronic liver disease patients with AD.

Objective To explore the method to carry out epidemiological investigation of chronic kidney disease (CKD) in rural area surrounding the Tarim Basin, and to elucidate the prevalence and risk factors associated with CKD among the Uygur adults in Moyu county. Methods A total of 1650 residents (age >18 years) from 15 villages in 3 rural town of Moyu county were randomly selected by using a stratified, multistage sampling. All the residents were interviewed and received physical examination and tested for random spot urine of albumin to creatinine ratio (ACR). Estimated glomerular filtration rate (eGFR) was calculated by modified factors of CKD were examined. Results Valid data of 1552 subjects were enrolled in the study. After the adjustment of age and gender component, the prevalence of albuminuria and reduced eGFR was 4.5% (95% CI 4.4-4.6) and 1.4% (95% CI 1.4-1.5) respectively. Approximately 5.4% subjects had at least one indicator of kidney damage. Age and hypertension were independently associated with CKD. Conclusions Experience and method of epidemiology investigation of CKD in the rural areas of Uygur are obtained through this study. The prevalence of CKD is 5.4% and the awareness is 12.5% in the Uygur adults of Moyu county. Independent risk factors associated with CKD are hypertension and age.

AIM: To seek a small interfering RNA ( siRNA ) sequence targeting rat inhibitor of nuclear factor kappa Bα ( IκBα) that can specifically and effectively suppress IκBα mRNA expression of rat ciliary muscles in vivo.METHODS:Three IκBα specific double stranded siRNAs were designed and synthesized. They were transfected into rat A7r5 cells which express IκBα gene. Flow cytometry was used to assess transfected efficiency. The mRNA and protein levels of IκBα were examined by Real Time quantitative polymerase chain reaction ( Real Time-PCR ) and western blot to screen a candidate valid sequence with the highest inhibitory rate. The Cy3 labeled non-specific control siRNA or the candidate valid siRNA was then injected into rat anterior chamber. Distribution of Cy3- siRNA in rat ciliary muscles was viewed by fluorescence microscopy, and the inhibitory effect in vivo of the valid siRNA was identified via Real Time-PCR and immunofluorescence. RESULTS: The suppression effect of the siRNA targeting the CTACGATGACTGTGTGTTT of IκBα gene was most obvious by vitro screening. By anterior chamber injection, this valid siRNA could reach rat ciliary muscles and effectively suppress IκBα gene expression with the highest inhibitory rate of 59. 0% on mRNA level at 24h after RNAi, and 52. 3% on protein level at 72h after RNAi (P<0. 01).CONCLUSION: It proves that the siRNA targeting the CTACGATGACTGTGTGTTT of IκBα gene is the valid sequence to suppress rat IκBα expression of ciliary muscles by RNAi in vivo.
