There is no reliable way to identify the high-risk patients with intermediate coronary artery lesions (diameter stenosis 20%-70%) in early stage. Soluble CXC chemokine ligand 16 (CXCL16) is a newly discovered chemokine that can mediate inflammatory responses. It is released by proteolytic cleavage of its membrane-bound form, named scavenger receptor for phosphatidylserine and oxidized lipoprotein (SR-PSOX) that can promote the uptake of oxidized low-density lipoprotein cholesterol by macrophages.

Objective: To study the effect of anticolchicine cytotoxicity of Dan Gua-Fang, a Chinesea Chinese), a Chinese herbal compound prescription on endothelial cells of vein (ECV304) cultivated in mediums of different glucose concentrations as well as the proliferation of those cells in the same conditions, in order to reveal the value of Dan Gua-Fang in preventing and treating endothelial damage caused by hyperglycemia in diabetes mellitus.

Methods: The research was designed as three stages. The growing state and morphological changes were observed when ECV304 were cultivated in the culture mediums, which have different glucose concentrations with or without Dan Gua-Fang and at the same time with or without colchicine.

Objective: To observe the effect on EPCs function by Xuefu Zhuyu Decoction.

Methods: After induced by serial concentrations of Xuefu Zhuyu Decoction-contained serum (XZDCS) and blank serum, EPCs proliferation, migration, adhesion and uptake function were detected by MTT, Boyden chamber, adhesion and uptake of ac-LDL respectively.

Results: Compared with the control group, 15% and 10% XZDCS could elevate the cell regeneration for 24 h and 48 h respectively.

The background, concept and status quo of translational medicine at home and abroad were introduced systematically in this review, and the application mode of translational medicine in the research and development of Chinese medicine (CM) was analyzed. Targeting the characteristics of CM and the changes in the spectrum of diseases in China, some suggestions were made to strengthen the translational research in CM and integrative medicine.

Objective: To investigate the effects of fosinopril sodium pre-treatment combined with ischemic postconditioning on rat serum and myocardial oxidative stress and proinflammatory cytokines post ischemia/reperfusion.

Methods: Sixty Sprague-Dawley rats were randomly divided into sham group (n = 15), ischemia/reperfusion group (30 minutes in situ occlusion of the left anterior descending artery followed by 1 hour reperfusion, n = 15), IPoC group (30 minutes occlusion of the left anterior descending artery followed by 3 cycles of 10 seconds of reperfusion/10 seconds of ischemia before 1 hour reperfusion, n = 15) and fosinopril sodium group [pretreated with fosinopril sodium (0.9 mg×kg(-1)×d(-1) for 14 days) followed by IPoC protocol at 2 h after the last gavage, n = 15].

Objective: To observe the effects of panax quinquefolius saponin (PQS) of stem and leaf on glucose-lipid metabolism and insulin signal transduction in the insulin resistant model of adipocytes.

Methods: The insulin resistant model of differentiated 3T3-L1 adipocytes was established in vitro with free fatty acid. After induction of insulin resistance, cells were treated with metformin or PQS for 2 days.

Aspirin is the most classic anti-platelet drug, plays its important role in preventing and treating cardio- and cerebro-vascular diseases for its excellent potency ratio; however, there exists individual difference in its anti-platelet effect, aspirin resistance (AR) presented in about 25%-40% of patients, which seriously influences the intervention effect of aspirin. So AR has become a clinical problem that attached more attention. In this paper, the authors put forward a new thinking for clinical studying and inventing new effective Chinese drugs on AR by means of screen out AR suffered from cardio/cerebro-vascular patients long-term received aspirin; find their gene difference sites from MtSNP to establish a foundation for AR predication and reasonable strategy formation; meantime, through platelet intervention in vitro adopting uniform design optimization method to explore the best compatibility and matching relationship of anti-platelet Chinese medicine for AR prevention and treatment, so as to fully display the multi-target intervening effects of Chinese drug-therapy.

Objective: To observe the pharmaceutical effect of Chinese drugs for activating blood circulation (Xiongshao Capsule, XSC, ) and for activating blood circulation and detoxification (Xiongshao Capsule and Huanglian Capsule, XSHLC, ) in terms of the indices of thrombosis, inflammatory reaction and tissue damage related factors in experimental carotid artery thrombosis rats.

Methods: Fifty Wistar rats were randomly divided into the sham operation group, the model group, the Simvastatin group (SG), the activating blood circulation (ABC) group, and the activating blood circulation and detoxifying (ABCD) group, with 10 rats in each group. Simvastatin (1.

In the West, hundreds of randomized controlled trials (RCTs) have been performed testing acupuncture. They include two types: those that compare acupuncture to other therapies, usual care or no treatment (pragmatic trials), and those that have placebo controls (efficacy trials). Acupuncture has generally performed well against other therapies or no treatment, but until recently, the evidence from placebo controlled trials has been considered equivocal or contradictory.

[Chemoinformatics study of tiaopi huxin recipe].

Zhongguo Zhong Xi Yi Jie He Za Zhi

February 2010

Objective: Virtual screening was performed to analyze Chemoinformatics of chemical components of Tiaopi Huxin Recipe (TPHXR) to provide guidance for its further research.

Methods: Distribution of some descriptors were described and principal component analysis (PCA) were performed to map these multiple descriptor values into a 2D plane. Molecular docking was conducted to determine the interaction between chemical components of TPHXR and key target enzymes of cardiovascular system.

Objective: To observe the effects of Chinese patent medicines with the function of replenishing qi to activate blood (RQAB) plus ischemic postconditioning (IPoC) in protecting myocardium of rats from ischemia-reperfusion (I/R) injury, and to explore the possible mechanisms.

Methods: Seventy-five Sprague-Dawley rats were randomly divided into sham-operated group (the suture was penetrated around the left anterior descending coronary artery, but not tied, n=15), I/R group (30 minutes of in situ transient occlusion of the left anterior descending artery, followed by 1 hour of reperfusion, n=15), IPoC group (30 minutes occlusion of the left anterior descending artery, followed by 3 cycles of 10 s of reperfusion/10 s of ischemia before 1-hour reperfusion, n=15), RQAB plus IPoC group (pretreated with 0.162 g/kg Xinyue Capsule and 0.

Article Synopsis
  • The study evaluates how C-reactive protein (CRP) levels affect the occurrence of in-stent restenosis after coronary procedures.
  • A meta-analysis was conducted on 9 prospective studies involving 1,062 patients, showing that higher CRP levels were linked to a greater risk of restenosis.
  • Results indicated a notable difference in CRP levels between patients with and without restenosis, particularly among those with unstable angina, while no significant correlation was found in stable angina patients.

Objective: To observe the effect of Xuefu Zhuyu Decoction ()-containing serum (XFZYD-CS) on endothelial progenitor cell (EPC) tube formation in vitro.

Methods: Mononuclear cells from rat bone marrow were prepared in a Ficoll density gradient centrifuge. EPCs were separated by the differential attachment method, and observed with inverted microscope for the effect of XFZYD-CS on EPC tube formation.
