AIM:To study the effects and mechanisms of a novel sulfonylureous compound 1 ｛4 [2 (4 bromobenzenesulfonaminoethyl)phenylsufonyl｝ 3 (trans 4 methylcyclohexyl) urea, G004, on antithrombosis. METHODS: The influence of compound G004 on the vasoconstrictor action, platelet aggregation and thrombosis formation was studied. The effects of compound G004 on the tail vein bleeding time in mice was examined. The influence of compound G004 on the release of prostanglandin I 2 and thromboxan A 2 from ECV304 cells was investigated. The measurement of cytosolic free Ca 2+ in attached ECV304 cells loaded with Fluo3/AM was carried out. RESULTS: Compound G004 did not inhibit the contraction of rat aorta rings induced by norepinephrine or potassium chloride, but potently inhibit human platelet aggregation challenged by arachidonic acid and adenosine diphosphate. Compound G004 significantly prolonged the tail vein bleeding time in mice and occlusion time of carotid artery in experimentally thrombotic rats. Compound G004 reduced mice mortality induced by the collagen plus epinephrine in a dose dependent manner. Compound G004 enhanced PGI 2 release and reduced TXA 2 secretion from ECV304 cells. G004 had no effect on the increase of cytosolic free Ca 2+ induced by patassium chloride. CONCLUSION: The compound G004 has a remarkable antithrombotic effect in vivo. Its active mechanism may be attributed to inhibition of platelet aggregation, enhancing PGI 2 generation and decreasing TXA 2 secretion from human umbilical vein endothelium.

BACKGROUND:Mesenchymal stem cels can secrete a variety of cytokines and growth factors that promote the survival of surrounding cels and play a paracrine role. OBJECTIVE:To investigate the effect of human umbilical cord mesenchymal stem cels on the proliferation and apoptosis of ectopic endometrial cels. METHODS:After isolation and culture, human umbilical cord mesenchymal stem cels and ectopic endometrial cels were co-cultured as observation group, and ectopic endometrial cels cultured alone served as control group. At 24, 48, 72 hours of culture, the proliferation and apoptosis of ectopic endometrial cels were detected by MTT and flow cytometry, respectively; RT-PCR was used to measure the expression ofPTEN gene in ectopic endometrial cels. RESULTS AND CONCLUSION:At 24, 48 and 72 hours, the proliferation of ectopic endometrial cels in the observation was inhibited significantly as compared with the control group, and the hypodiploid peak ratio also increased significantly (P < 0.05). Over time, the cel inhibition rate was gradualy declined, and there were significant differences at different time points (alP < 0.05). Compared with the control group, the expression of PTEN gene was up-regulated significantly in the observation group (P < 0.05). In the observation group, the expression ofPTEN gene at 48 and 72 hours was significantly higher than that at 24 hours (P < 0.05). These findings indicate that in the human umbilical cord mesenchymal stem cels can inhibit the proliferation of ectopic endometrial celsin vitro and promote their apoptosis by up-regulation ofPTEN mRNA expression.

Protocarcinogenic gene Her-2/neu was closely related to the development of gastric cancer. Herceptin is an antibody according to Her-2/neu and is used for treating breast cancer. Topo Ⅱ α is the important Nuclear enzymes needed by DNA duplicate, and is closely related to the proliferation of malignant tumors, so it is the important target enzymes of cancer chemotherapy. Her-2/neu and Topo Ⅱ α are located in the same chromosomes, there are correlation between the two genes' proliferation or loss. We reviewed the expression of Her-2/neu and Topo Ⅱ α in the stomach and the new progress of the correlation between the two genes home and abroad in this paper, which provides new methods for the prevention and treatment of gastric cancer.

A simple colorimetric method for detection of isocarbophos was developed based on the enhanced peroxidase-like activity of hemin. Hemin could catalyze the oxidation of peroxidase substrate 3,3′,5,5′-tetramethylbenzidine (TMB) by H2O2, which made TMB to lose one electron and caused reaction solution color changing from initial transparent to blue-green. Adding isocarbophos improved hemin affinity to substrates, which further enhanced peroxidase-like activity of hemin and made TMB to lose two electrons. The color of TMB solution was further changed from blue-green to yellow, and the degree of color change was proportional to the concentration of isocarbophos. Under the optimal conditions, the present analytical method for isocarbophos detection had a dynamic range from 2 μg/L to 100 μg/L with a detection limit of 1.2 μg/L (3σ). The selectivity assay demonstrated that other organophosphorus pesticides exhibited negligible interferences for isocarbophos detection. The application of the proposed method in the practical samples showed that the mean recovery of isocarbophos was in the range of 94.4％-113.0％, thus it could be widely applied to rapidly and sensitively detect isocarbophos in the agricultural products.
