Objective: To observe the protective effect of ischemic post-conditioning on myocardial reperfusion injury with the potential mechanism in experimental rabbits. Methods: A total of 36 healthy New Zealand rabbits were divided into 6 groups:①Sham group,②Ischemic reperfusion control (CON) group,③Myocardial ischemic post-conditioning (MpostC) group,④Remote ischemic post-conditioning (RPostC) group,⑤MPostC+5-HD group,⑥RPostC+5-HD group.n=6 in each group. The ischemic reperfusion injury model was established by left ventricular descending artery occlusion for 45 min followed by reperfusion for 120 min. Bilateral external iliac artery was occluded for 5 min to induce the short skeletal muscle ischemia. The indexes of cardiac function and plasma CK , LDH activities were measured at baseline, end of ischemia and 1, 2 h after reperfusion respectively, the sizes of myocardial infarction (MI) were examined and compared among different groups. Results: ①Compared with CON group, the indexes of cardiac function were improved in MPostC and RPostC groups at 1, 2 h after reperfusion,P<0.05, and compared with MPostC group and RPostC group, the indexes of cardiac function were improved in MPostC+5-HD and RPostC+5-HD groups,P<0.05.②Compared with CON group, plasma CK, LDH activities were decreased in MPostC and RPostC groups at 2 h after reperfusion,P<0.05, and compared with MPostC group and RPostC group, the CK, LDH activities were increased in MPostC+5-HD and RPostC+5-HD groups,P<0.05.③The ischemic ranges and areas were similar between CON group and the other 5 groupsP>0.05. The MI ranges and areas in MPostC and RPostC groups were much less than that in CON group,P<0.05, and compared with MPostC group and RPostC group, the MI ranges and areas increased in MPostC+5-HD and RPostC+5-HD groups,P<0.05. The MI ranges and areas were similar between CON group and MPostC+5-HD, RPostC+5-HD groups,P>0.05. Conclusion: Classical ischemic post-conditioning and remote organ ischemic post-conditioning both have protective effect on myocardial reperfusion injury in experimental rabbit, which might be related to the activation of mitochondrial ATP-sensitive potassium channels.

Objective To explore the effect of araloside on the proliferation and apoptosis of HeLa cells.Methods Human cervical cancer cell line HeLa was cultured in vitro,the experiment was divided into 4 groups as follows:blank group,araloside trea-ted groups(50,100,200 μg/mL).Normal saline and araloside (50,100,200 μg/mL)were gave,respectively.24,48 and 72 hours lat-er,the cells were collected.Cell proliferation was detected by MTT,cell apoptosis was determined by flow cytometry,the expression of pAkt1,pIкBα,NF-κB (p65),Bcl-2 and Caspase-3 were evaluated by western blot.Results Araloside obviously inhibited the pro-liferation and increased the apoptosis level of HeLa cells in a time-dose dependent manner.Moreover,Araloside significantly de-creased the phosphorylation of Akt1 and IκBα,reduced the expression of NF-κB(p65)and Bcl-2,whereas obviously increased Caspase-3 content.Conclusion Araloside could inhibit the proliferation and promote the apoptosis of HeLa cells via suppressing Akt/NF-кB signaling pathway.

Clinical medicine and its teaching patterns put forward the new demand to the teaching of laboratory diagnostics. According to the teaching objectives and development tendency of laboratory diagnostics, a novel teaching pattern based on organ-system diseases was established through systematical reform measures. The course content system was reconstructed and focused on the diseases. And the professional teacher group carefully orchestrated, applied new teaching methods,such as case-based learning and problem-based learning. The independent learning on a resource sharing network platform was encouraged, and the evaluation system was innovated. The novel teaching pattern has obtained gratifying achievement, and showed a bright prospect of development.

Objective To explore the inhibition role of araloside on cervical cancer HeLa cell proliferation and migration to reveal the molecular mechanism of NF-κB in HeLa cell in the process of tumor suppression.Methods The in vitro cultured cervical cancer HeLa cell line served as the research object.The experiment was divided into the control group and araloside(200 μg/mL) treatment group(observation group).The change of proliferation and migration ability after 48 h were observed in the two groups.Western blot was used to detect the expression of NF-κB molecule and change of autophagy involved protein Beclin 1 and LC3B.Results Araloside could significantly inhibit the proliferation and migration of HeLa cells and the NF-κB signaling pathway,and promoted the expression of autophagy related molecule Beclin 1,Atg 5 and LC3B.Conclusion Araloside could inhibit the NF-κB signaling pathways,thus induces autophagy occurrence and influences the proliferation and migration of cervical cancer HeLa cells.

Objective: To investigate the preventive effect of alprostadil (prostaglandin E1) combining hydration therapy on contrast induced nephropathy (CIN) after percutaneous coronary intervention (PCI) in elder patients. Methods: A total of 175 patients with coronary artery disease (CAD) elder than 75 years received PCI in our hospital from 2011-03 to 2014-03 were retrospectively studied, those including 122/175 (69.71 %) with male gender. The patients were at the mean age of (74.7 ± 3.9) years and randomly allocated into 2 groups: Control group, based on routine treatment, the patients received regular hydration of intravenous normal saline 1 ml/(kg?h) at 6 hours prior and 12 hours after PCI,n=84 and Alprostadil+hydration group, based on routine treatment and regular hydration, the patients received intravenous alprostadil 10μg in 100ml normal saline twice a day at 1 day prior PCI and the 3rd day after PCI,n=91. The serum levels of creatinine (SCr) were examined prior PCI and 3 days continuously after PCI, creatinine clearance rates (Ccr) were calculated and the CIN occurrence rates were compared between 2 groups. Results: At the 3rd day after PCI, the mean SCr level in Alprostadil+hydration group (92.08 ± 21.65) μmol/L was lower than Control group (99.43 ± 22.77) μmol/L,P<0.05, the mean Ccr level in Alprostadil+hydration group (63.78 ± 20.58) ml/min was higher than Control group (57.09 ± 22.31) ml/min,P<0.05. The occurrence rate of CIN after PCI was higher in Control group (13.1%, 11/84 patients) than Alprostadil+hydration group (3.3%, 3/91 patients),P<0.05. Conclusion: Alprostadil combining hydration therapy may obviously protect renal function and reduce the incidence rate of CIN in elder CAD patients after PCI treatment.

Drug delivery system targeting immune system plays an important role in the treatment of inflammatory diseases.Drug delivery system targeting immune system could target immune cells or immune organs.It could be divided into active targeting mediated by the interaction of ligand-receptor or antigen-antibody and passive targe-ting mediated by pH;particles and so on.This review summarizes new progress for drug delivery system targeting immune system;which provides a theoretical reference for designing the safe and effective drug delivery system and providing efficient and safe treatment for inflammatory diseases.
