Objective By studying the expressions of vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) in rats′ cardiac muscle after acute myocardial infarction, we try to find out the relation between the expression of these two factors and the formation of new blood vessels under ischemia. Methods Wistar rats were divided into control group and infarction group (3, 7, 14, 28, 42, 56 d). The expression of VEGF and bFGF in cardiac muscle and endothelial cells is detected by means of immunohisto-chemial staining while the density of newly formed ressels is detected by marking the endothelial cells with antigens associated with factor Ⅷ. Results After ligating the left anterior descending coronary artery of the rats, the expression of VEGF and bFGF increased along with the prolongation of myocardial ischemia and reached the peak on the 7th day. The expression of the 2 factors began to decrease on the 28th day and the most significant decrease happened on the 42th and 56th day. The density of the newly formed capillaries is directly propontimal to the levels of the 2 factors. Less expression of VEGF and bFGF was observed in the control group. Conclusion The up-regulation of VEGF and bFGF expression might play important roles in neovascularization. Dicrectly intramyocardial injection of bFGF and VEGF gene at the time when the expression of bFGF and VEGF began to decrease maybe optimal.

Objective To evaluate the effectiveness of treating depressive patients with somatic symptoms with combined TCM and western medicine.Methods 69 patients were randomly divided into 2 groups:a combined therapy group (treated with Yangyin-Qinggan decoction and paroxetine) and mono-therapy (treated with paroxetine alone as an active control),The depressive and somatic symptoms were assessed before (0 week),during (2 weeks and 4 weeks) and at the end point (8 weeks) of the treatment.Results ①Both therapies alleviated the depressive symptoms:HAMD assessed among patients receiving combined therapy are listed as:(0 week:19.29±2.38),(2 weeks:17.38 ± 2.37),(4 weeks:15.27 ± 2.15),(8 weeks:13.35 ± 2.09) ;combined therapy started to ease the depressive symptoms after 2 weeks of treatment (2 week compared with 0weeks),similar improvements could also be noticed after 4 weeks of treatment 4 weeks with 2 weeks:P＜0.05)and at the end of this research (after 8 weeks of treatment:8 weeks with 4 weeks:P＜0.05).HAMD for mono-therapy are as:(0 week:18.69±3.03),(2 weeks:16.63±3.09),(4 weeks:15.20±2.95),(8 weeks:14.60±2.72) ; mono-therapy started to alleviate the depressive symptoms also,after 2 weeks of treatment (2 weeks compared with 0 week:P＜0.05),yet only slight improvements could be seen after 4 weeks (4 weeks with 2 weeks:P＞0.05) and 8 weeks of the treatment (8 weeks with 4 weeks:P＞0.05).The combined therapy turned to be more effective in alleviating depressive symptoms at the end point of the treatment (P＜0.05).②In terms of improving the somatic symptoms,the Somatization Symptom Scale (SSS) among patients with combined therapy were as follows:(0 week:48.74±4.07),(2 weeks:46.74±4.16),(4 weeks:43.74±3.77),(8 weeks:41.18 ± 3.50) ; Combined therapy was witnessed to start to ease those symptoms after 2 weeks o f treatment (2week compared with 0 weeks,P＜0.05),similar patterns were found again,after 4 weeks (4 weeks with 2 weeks:P＜0.05) and 8 weeks of the treatment (8 weeks with 4 weeks:P＜0.05).Mono-therapy was found to ease the somatic symptoms in a less-effective way,yet no difference was found between any two SSS after 2 weeks,4weeks or 8 weeks of treatment (P＞0.05,respectively).Combined therapy was better at improving the somatic symptoms (P＜ 0.01).Conclusion Combined therapy proved to be more effective in both relieving depression and somatic symptoms.
