Objection To compare the efficacy and tolerance of perioperative intravenous Metoprolol or calcium iron antagonist injection on patients with cardiac complications which undergoing noncardiac surgery. Method The clinical data of 135 patients who underwent noncardiac surgery from March 2003 to May 2004 was analyzed. According to the different drugs used to treat the perioperative cardiac complications (tachycardia arrhythmia, hypertension and myocardium ischemia), patients were allocated to metoprolol group (87 cases) and calcium antagonist group (48 cases, including Verapamil 21 patients and Diltiazem 27 patients). The effects of the therapy on heart rate and blood ressure control and ischemia relieving were compared between two groups. Results There is no significant difference at baseline data between two groups. Compared with calcium antagonist, intravenous metoprolol could more reduce heart and relieve myocardium ischemia quickly. The effect of blood pressure controlling was more significant in calcium antagonist group than in metoprolol group. The incidence of side-effects events was lower in metoprolol ( 8.0%) than in calcium antagonist group (22.9%).Conclusions Intravenous metoprolol injection is effective and safe in treating perioperative cardiac complications in patients with noncardias surgery.

Before and after the 14-day treatment,the clinical symptom and serum level of PAG, P-selectin were measured,and exercise electrocardiography was performed. Results After treatment with Depside Salt from Salvia Miltiorrhiza,the symptom of angina pectoris was alleviated and exercise ECG was improved,while no significant difference was found compared with control group.Serum PAG and P-selectin were decreased after treatment with Depside Salt from Salvia Miltiorrhiza ,and significantly more than Danshen.Conclusion Depside Salt from Salvia Miltiorrhiza injection can remarkably inhibite the aggregation and activation of platelet,and is effective for angina pectoris.

Objective To compare the effects of clopidogrel and ticlopidine in combination with aspirin in preventing direct coronary stenting complication in patients with acute myocardial infarction.Methods The clinical data of 74 cases with ST-segment elevation myocardial infarction were retrospectively analysed. The patients were divided into two groups. Before direct coronary stenting, clopidogrel,300mg loading dose then 75mg once daily or ticlopidine 250mg twice daily in addition to aspirin 100mg once daily were given to two groups respectively. Hemorrhage, neutropenia, thrombocytopenia were observed during 4 weeks. The frequency of clinical cardiovascular events (including cardiac mortality, myocardial re-infarction, need for revascularization) were followed up at 6 months. Results The incidence of major cardiac events in clopidogrel group was less than ticlopidine group ( 21.1% with Clopidogrel and 44.4% with Ticlopidine,P= 0.031). The incidence of light hemorrhage patents individually were 6(15.8%) vs 14(38.9%). The mean number of neutrophile white celll individually were 5.8 ?1.7 vs 4.2 ?3.6 (?10 9/L). The platelet count were 130.3 ?42.1 vs 89.2 ?53.3(?10 9/L), P

BACKGROUND: Results from clinical trials suggested that clopidogrel and ticlopidine had side effects of granulopenia, and aspirin could inhibit endothelial progenitor cell proliferation. There is no report of effects of these drugs on human bone marrow mesenchymal stem cells (hBMSCs) in stem cell transplantation. OBJECTIVE: To investigate the effects of antiplatelet drugs including clopidogrel, ticlopidine and aspirin on hBMSC proliferation and secretion. DESIGN, TIME AND SETTING: The cytology in vitro observation was performed at the Laboratory of Toxicology, Shanghai Municipal Center for Disease Control and Prevention from March to December 2006.MATERIALS: The second passage of hBMSCs was kindly donated from Shanghai Tissue Engineering Research & Development Center, Shanghai Ninth People's Hospital. Clopidogrel (Lot number J20040006) and ticlopidine (Lot number H19980186) were obtained from Hangzhou Sanofi-Synthelabo Minsheng Pharmaceutical CO., Ltd. Aspirin (Lot number 20050059) was obtained from Bayer Vital GmbH. METHODS: The standard culture medium consisted of DMEM-LG, 10% heat-inactivated FBS, 100 U/mL penicillin and 100 μg/mL streptomycin. After being cultured in vitro expanded out to passage 6, hBMSCs were treated with antiplatelet drugs of different concentrations and compared with control group. MAIN OUTCOME MEASURES: Cell proliferation was assessed by 3- (4, 5-dimethylthiazol -2-yl)-2,5-diphenyltetrazolium bromide (MTT) colorimetric assay, level of vascular endothelial growth factor (VEGF) of culture medium was detected by enzyme-linked immunoadsordent assay (ELISA), and surface antigens of hBMSCs were analyzed by the flow cytometry. RESULTS: A570 values of hBMSCs treated by clopidogrel or ticlopidine of 0.02,0.1,0.4,2,10,40 μmol/L were higher than control group (P < 0.01), while A570 values of aspirin group of 60, 600, 2 000 μmol/L were lower than control group(P < 0.05). Antiplatelet drugs had no obvious effect on cell surface antigens(CD34, CD105, CD106)expressed by hBMSCs. Treated by high dose clopidogrel or ticlopidine (40 μmol/L), VEGF level from hMSCs was lower than that of control group(P < 0.01), but VEGF level of low dose (0.02 μmol/L) ticlopidine group was higher than control group(P < 0.01), and there was no significantly difference of VEGF level among low dose clopidogrel group (0.02 μmol/L), aspirin group (5, 2 000 μmol/L), and control group(P > 0.05). CONCLUSION: Clopidogrel and ticlopidine improve proliferation of hBMSCs, but aspirin inhibits proliferation of hBMSCs. High dose of clopidogrel and ticlopidine suppress VEGF secretion of hBMSCs, while low dose of ticlopidine promote it. Antiplatelet drugs have no obvious effect on hBMSCs differentiation.
