In insulin-secreting cells, expression of NADPH oxidase (NOX), a potent source of ROS, has been reported, along with controversial findings regarding its function. Here, the role of NOXs was investigated: first by expression and cellular localization in mouse and human pancreatic islets, and then by functional studies in islets isolated from Nox(More)
The sodium iodide symporter (NIS) present in the membranes of thyroid cells is responsible for the capacity of the thyroid to concentrate iodide. This allows treatment of thyroid cancers with (131)I. We propose to enlarge the therapeutic strategy to hepatocellular carcinomas by using hepatoma-specific promoter and enhancer for targeted radiotherapy. We(More)
OBJECTIVE To investigate the effects of drug-containing serum of Chinese herbal compound, Xiongshao Capsule (, XS, for activating-blood) and Huanglian Capsule (, HL, for dispellingtoxin) on the oxidized low-density lipoprotein (ox-LDL)-induced inflammatory factors in human umbilical vein endothelial cells (HUVECs). METHODS Thirty-two rats were randomly(More)
AIMS Estrogen plays a protective role in atherosclerosis. Our preliminary work demonstrated that the active conformation of Tanshinone IIA(TanIIA) is similar to the 17β-estradiol and it can bind to the estrogen receptor. Here, we hypothesized that Tanshinone IIA might have anti-inflammatory and anti-oxidative effects in atherosclerosis, mediated through(More)
BACKGROUND Ischemic postconditioning (IPOC) has been suggested to reduce ischemic reperfusion injury. It remains unclear whether the activation of phosphatidylinositol 3 kinase (PI3K)/Akt is a causal mechanism in the cardioprotection afforded by IPOC, which was examined in the model of percutaneous transluminal coronary angioplasty (PTCA) minipigs.

OBJECTIVE To explore the synergistic protection of Danhong Injection (丹红注射液, DHI) and ischemic postconditioning on myocardial reperfusion injury in minipigs. METHODS Acute myocardial infarction model was made by balloon occlusion in left anterior descending coronary artery (LAD) of minipigs, and then postconditioning was simulated through(More)
Channel gating in response to extracellular ATP is a fundamental process for the physiological functions of P2X receptors. Here we identify coordinated allosteric changes in the left flipper (LF) and dorsal fin (DF) domains that couple ATP-binding to channel gating. Engineered disulphide crosslinking or zinc bridges between the LF and DF domains that(More)
Through summarizing the literatures concerning basic and clinical study on the correlation between blood-stasis syndrome (BSS) and inflammation, reviewing close correlation of BSS with C-reaction protein, serum interleukin-6, tumor necrosis factor and adhesion molecules, it was found that promoting blood circulation and removing stasis approaches could(More)
OBJECTIVE To investigate the differential gene expression profiles in coronary heart disease (CHD) patients of blood-stasis syndrome (BSS) by oligonucleotide microarray technique, and the clinical significance of target gene. METHODS Subjects were assigned to CHD patients with BSS (n=8), CHD patients without BSS (n=8), and BSS patients without CHD (n=8)(More)
OBJECTIVE To observe the regulatory effect of Chinese drugs for activating blood circulation (ABC) and for activating blood circulation and detoxifying (ABCD) on indices of thrombosis, inflammatory reaction, and tissue damage in a rabbit model of toxin-heat and blood stasis syndrome. METHODS Fifty-four rabbits were randomized into the normal control(More)
