Objective To explore the influence of candesartan (an angiotensin II receptor 1 antagonist,AT1R) in radioresistance of human nasopharyngeal carcinoma CNE1 cells.Methods Cell growth of CNE1 with or without candesartan treatment was measured in vitro by MTT method;radiosensitivity of CNE1 with or without candesartan treatment was tested under normoxic or hypoxic conditions by clone formation assay.The expression of hypoxia-induced factor 1α(HIF-1α)in CNE1 cells was analysed by western blotting.Results Candesartan did not significantly inhibit the growth of CNE 1 cells in both normoxic and hypoxic conditions.Candesartan also did not influence the radiosensitivity of CNE1 cells in normoxic condition;however,it significantly increased the radiosensitivity of CNE1 cells in hypoxic condition.The expression of hypoxia-induced factor 1 α (HIF-1 α)in hypoxic CNE1 cells was significantly inhibited by candesartan treatment.Conclusion Candesartan does not significantly influence the proliferation of CNE1 cells in both normoxic and bypoxic conditions but significantly enhances the radiosensitivity of hypoxic CNE1 cells,in which the mechanisn may be involved in its inhibiting HIF1α expression in hypoxic CNE1 cells.

Objective To explore the mechanism by which tumor necrosis factor alpha(TNF-α) induces RIP1 kinase-dependented apoptosis in L929-A fibroblastoma cells.Methods The sub-mitochondrial localization of receptor-interacting protein 1(RIP1),caspase-8 and Bid proteins was detected by dose-gradient trypsin digestion and Western blotting.The levels of reactive oxygen species (ROS),intracellular calcium concentration,mitochondrial membrane potential (MMP),and cellular adenosine triphosphate(ATP) content were determined by fluorescent probe labeling and flow cytometry assay.The mitochondrial respiratory chain complex Ⅰ and Ⅲ activities were detected by commercial kits.Nec-1,A RIP1 kinase specific inhibitor,and RIP1-/-or Bid-/-L929-A cells were used to detect the roles of RIP1 kinase and Bid protein in cell death.Results RIP1,caspase-8 and Bid proteins were co-located in the outer membrane of mitochondrial.TNF-α exposure for 3 h could induce Bid cleavage,inhibit mitochondrial respiratory chain complex Ⅲ activity and reduce MMP.Following these changes and after TNF-α exposure for 6-12 h,the intracellular calcium concentration and ROS were increased,whereas the ATP concentration was decreased,and the cells were killed.Inhibiting RIP1 kinase or knockdown RIP1 or Bid protein could suppress all the cytotoxic effects of TNF-α.Conclusion TNF-α treatment can result in RIP1 kinase-mediated Bid cleavage and inhibit mitochondrial respiratory chains and cell energy metabolism,which ultimately leads to the death of L929-A cells.

Objective To compare the prognosis of vascular in situ and bridge vessel percutaneous coronary intervention ( PCI) therapy strategies in patients with recurrent angina after coronary artery bypass grafting ( CABG) . Methods A total of one hundred and two patients with recurrent angina after CABG from January 2008 to January 2016 were involved in this study and were divided into two groups according to interventional therapy strategy:74 patients in the vascular in situ PCI group ( in situ group,74 cases) and 28 patients for bridge vessel PCI group ( bridge vessel group,28 cases) . The patients have been followed up for (33. 6± 10. 2) months. The major adverse cardiovascular events ( MACE) of the two groups were recorded, including non?fatal acute myocardial infarction ( AMI) ,target vessel revascularization ( TVR) and cardiac death, and multivariate logistic regression analysis was used to analyze the related factors of MACE. Results Compared with the bridge vessel group,the non?MACE survival rate,non?AMI survival rate and non?TVR survival rate of the in situ group were significantly increased ( ( 71. 6% ( 53/74 ) vs. 57. 1% ( 16/28 ) , 93. 2% ( 69/74 ) vs. 82. 1% (23/28),81. 1% (60/74) vs. 67. 9% (19/28) ),the differences were statistically significant (χ2=8. 141,4. 219,5. 436, P<0. 05) . Multivariable logistic regression analysis showed that age of bridge ( OR=1. 023,95%CI 1. 005-1. 026,P=0. 019) ,diabetes mellitus ( OR=2. 386,95%CI 1. 425-3. 991,P=0. 003) and bridge vessel PCI (OR=1. 884,95%CI 1. 093-3. 220,P=0. 025) were factors that affect the clinical prognosis in patients with recurrent angina pectoris after CABG. Conclusion The clinical prognosis of the in situ PCI is better than bridge vascular PCI in patients with recurrent angina after CABG,while the age of bridge, diabetes mellitus, vascular interventional treatment are factors for the effect of interventional therapy patients prognosis. The clinical prognosis is much better in native vessel PCI than that of bridge vessel PCI in patients with recurrent angina after CABG. The age of bridge,diabetes mellitus and bridge vessel PCI are the factors that affect the clinical prognosis in the patients.

Objective To compare the efficacy of native vessel percutaneous coronary intervention (NV-PCI) and optimal drug therapy (ODT) in patients with recurrent angina after coronary artery bypass grafting (CABG). Methods The clinical data of 142 recurrent angina pectoris after CABG patients who had underwent coronary angiography were retrospectively analyzed. Among the patients, 70 cases were treated with NV-PCI (NV-PCI group), and 72 cases were treated with ODT (ODT group). The incidence of major adverse coronary events (MACE) and left ventricular ejection fraction (LVEF) were compared between 2 groups. Results All patients were followed up for at least 1 years. There were no statistical differences in the number of bypass vessels and number of occluded vessels between ODT group and NV-PCI group: (2.5 ± 0.7) branches/case vs. (2.4 ± 0.9) branches/case and (1.4 ± 0.9) branches/case vs. (1.3 ± 0.7) branches/case, P>0.05. The incidence of MACE in NV-PCI group was significantly lower than that in ODT group: 12.9% (9/70) vs. 22.2% (16/72), and the LVEF was significantly higher than that in ODT group:(63.5 ± 14.0)%vs. (57.1 ± 9.0)%, and there were statistical differences (P<0.05). Conclusions Compared with the ODT, the NV-PCI has lower incidence of MACE and higher LVEF in patients with recurrent angina pectoris after CABG.
