Objective To discuss the effect of early combined therapy of sertraline and psychotherapy on the rehabilitation of the patients with post-stroke depression (PSD)and observe its effect on plasma and platelet serotonin(5-HT). Methods All of 130 patients with PSD were divided into sertraline treatment group (65 cases) and routine treatment group (65 eases). Every patient was given routine treatment according to treatment guideline of cerebrovascular disease after admission. The sertraline treatment group received twelve-week sertraline treatment and psychotherapy, while the routine treatment group only received psychotherapy. Patients were evaluated by HAmilton rating scale for depression (HRSD) and serf-rating depression scale (SDS) before treatment and at the ends of the 4th and 8th week treatment, respectively. Meanwhile, the levels of plasma and playlet 5-HT of every patient were measured by the enzyme immunoassay methods. Results The scores of HRSD and SDS were lower in sertraline treatment group than those in routine tretment group at the ends of the 4th and 8th week. The rate of decrease of HRSD and SDS in sertraline treatment group was higher than that in routine treatment group at the end of the 8th week (Pall<0.01).The levels of platelet 5-HT in sertraline treatment group was lower at the ends of the 4th and 8th week than those before, treatment (P< 0.01).No significant change in plasma 5- HT level could be observed before and after treatment in two groups(P> 0.05). Conclusions Early treatment by sertraline can release the symptom of PSD and promote rehabilitation of PSD patients. The sertraline treatment can reduce the level of platelet 5- HT in PSD patients. However, the effect of plasma 5-HT value is not clear.

Objective To observe the hypoglycemic mechanism of total saponins of Momordica charantia (MC) in type 2 diabetes mellitus (DM) rats. Methods Among the selected 60 male Specific Pathogen Free (SPF)rats, 8 were random- ly chosen as control group, while others were fed with high fat and high glucose diet following streptozotocin injection from caudal vein 8 weeks after to construct type 2 DM models. After the DM models were successfully built, rats were then ran- domized into five groups: DM control group (n=8), the metformin group (n=8) and three groups of total saponins of MC with different dosage (n=8 in each group). The total saponins of MC groups include DM rats administrated with total saponins of MC 100, 200, 400 mg/(kg·d) for 8 weeks, the metformin group include DM rats administrated with metformin 50 mg/(kg·d) for 8 weeks. At the end of the experiment, the fasting blood glucose and insulin were examed. At the same time, a part of pan- creas islet, liver and skeletal muscle were preserved. The pancreas islet structure, the hepatic glycogen and Glucose trans- porter 4 (GLUT4) expression were observed by electron microscope, glycogen dyeing and immunoblot respectively. Results After 8 weeks treatment, compared to type 2 DM control group, fasting blood glucose and insulin values in MC groups were reduced more obviously. However, skeletal muscle GLUT4 expression level, insulin granules and hepatic glycogen increased obviously in MC groups. Conclusion Total saponins of MC has hypoglycemic effect. It’s mechanisms maybe include pro- moting the hepatic glycogen synthesis, inhibiting the hepatic glycogen decomposition and promoting insulin sensitivity by in- creasing peripheral tissue’s GLUT4 expression.
