RESUMEN
Aim: To search for new compounds with stronger anti-inflammatory activities and less gastrointestinal side effects. Methods: 2-(2, 4-Dichlorophenyl) -3-(3, 5-dimethoxyphenyl) - propenoic acid(Ⅰ) was converted to amides(Ⅱ). Their anti-inflammatory activities against xylene-induced mice ear swelling were evaluated. Results: Twelve target compounds (Ⅱ_(1-12)) were synthesized, and their structures were confirmed by IR,~1H NMR and HR-MS.Ⅱ_3 exhibited significant anti-inflammatory activity compared with CMC-Na ( P < 0. 01) and aspirin ( P < 0. 05). Conclusion: Compound Ⅱ_3 deserves further investigation.
RESUMEN
<p><b>OBJECTIVE</b>To investigate the therapeutic effects of Ginkgo biloba extract (EGb) in rats with acute myocardial injury induced by isoproterenol (ISO).</p><p><b>METHOD</b>The rats, induced by Isoproterenol (4 mg x kg(-1) x d(-1), 10 d, sc), were divided into groups: sham, model, metoprolol (10 mg x kg(-1) x d(-1), 13 d, ig), EGb (100 mg x kg(-1) x d(-1), 13 d, ig).</p><p><b>RESULT</b>The cardiac parameters of the Model group were compromised significantly in both systolic and diastolic function. Improvement in cardiac function by EGb was significant. In model groups, plasma activities of AST, LDH, CK, HBDH, CKMB and ventricular weight index (LV and RV/BW) were elevated significantly. With the treatment with EGb and metoprolol, the enzymes and ventricular weight index were significantly ameliorated.</p><p><b>CONCLUSION</b>G. biloba extract was beneficial to cardiac performance by improving myocardium enzymes and cardiac function in isoproterenol induced myocardial injury in rats.</p>

Objective:To study treatment of complications of laryngopharyngitis induced by gastroesophageal reflex disease(GERD)mainly by Banxia Xiexin Decoction.Methods:The treatment group of 40 cases was treated by Banxia Xiexin Decoction and the control group of 38 cases was treated by Jinsang Liyan Pill.Results:The therapeutic effects for complications of paryngopharyngitis, GERD symptoms,gastroscope grading,and laryngoscope examination in the treatment group were significantly superior to those in the control group(P
RESUMEN
AIM: To observe the effect of crocetin on the apoptosis and the changes of its related regulating proteins caspase-3 and Bcl-2 expression induced by hydrogen peroxide (H_2O_2) in cultured cardiomyocytes. METHODS: Changes of cellular morphology were detected under microscope. Apoptosis rates of the cells were analyzed by PI staining with flow cytometry. Expressions of caspase-3 and Bcl-2 proteins in the cells were determined by immunofluorescence with flow cytometry. RESULTS: In the concentrations used, more severe morphological changes with higher apoptosis rate of the cultured myocardial cells were seen in each H_2O_2 group than that in control group. When treated with 1?10 -4 mol?L -1 H_2O_2, the caspase-3 was increased and Bcl-2 protein decreased remarkably in the cells. But each dosage of crocetin, especially the highest one (5?10 -5 mol?L -1, P
