Objective To investigate the therapeutic effect and its mechanism of pathogenicity of streptozotocin diseased rats treated by the mixture of kelp extract, wolfberry, and Chinese yam. Methods Streptozotocin-diabetic rat model were taken the mixture of kelp extract, wolfberry and Chinese yam with the ratio of 1:1:1 by intragastric administration. positive control group was fed metformin of 83.5mg/kg, the control group and the model group were given the same amount of distilled water. The safety of high dose (1500 mg) of the mixture therapy for the normal rat were evaluated, their blood glucose levels, glucose tolerance, body weight and insulin levels were observed and its possible mechanism were analyzed. Results Compared with the model group, the disease diabetic rats of the administered group (250mg/kg,500mg/kg,1500mg/kg) were significantly alleviated. First of all, coat color was more shiny, the behavior were more physical agility. Followed by the decrease of blood glucose levels and AUC, and body weight and insulin levels were elevated. In cell experiments, the number of islet cells was increased in the administered group by the mixture in a dose-dependent manner. Conclusion The mixture of kelp extract, wolfberry, and Chinese yam had obvious hypoglycemic effect. The hypoglycemic activity of the mixture may be attributed to increase insulin secretion through inhibit apoptosis of islet β-cells.

Objective To study efficiency and safety of fondaparinux and Enoxaparin in treatment of Chinese patients with acute coronary syndrome (ACS) having undergone percutaneous coronary intervention (PCI). Methods One thousand and sixty ACS patients (945 with unstable angina, 115 with AMI) having undergone PCI in Henan provincial hospital from July 2011 to July 2013 were randomized into two groups treated with fondaparinux or enoxaparin respectively. Apart from treatment with oral aspirin and clopidogrel, those in the former group were treated with fondaparinux (2.5 mg IH QD) and the latter with enoxaparin (60 mg IH Q12H) subcutaneously for 2 days before operation, both suspended for 12 h before the operation. All of the patients were given heparin (60 IU/kg) during the operation. After the operation, the therapies with fondaparinux (2.5 mg IH QD) and enoxaparin (60 mg IH Q12H) were resumed subcutaneously for 3 days. Perioperative observation and follow-ups were made in terms of hemorrhage, thrombosis and major adverse cardiac events (MACE) in the patients during the hospitalization period, 2 and 4 weeks after operation. Results Fondaparinux and enoxaparin are both effective on anticoagulation for the patients after PCI. There was no significant difference about the incidence of MACE between the two groups (P > 0.05). But, fondaparinux group had lower incidence of hemorrhage than enoxaparin group (P < 0.05). Conclusion Fondaparinux and enoxaparin both have good anticoagulant activity in Chinese patients with ACS undergoing PCI, but fondaparinux may lower the risk of hemorrhage compared to enoxaparin.
