Objective To observe the effect of Tongxinluo capsule combined with Jinlidas intervention on vascular endothelial fuction and blood glucose in the patients with Type 2 diabetes. Methods A total of 100 patients with Type 2 diabetes were randomly divided into treatment and control groups with 50 patients each. Both groups were received subcutaneous injection insulin, oral admistration of Simvastatin and Aspirin. And the treatment group were received Tongxinluo capsule and Jinlida sintervention based on the standard treatment. The changes of serum levels of FPG, 2hPG, HbAlc, VEGF, NO, ET-1 were observed before and after treatement. All the patients were treated for 12 weeks. Results After the treatment, the serum of FPG (7.03 ± 2.11 mmol/L vs. 8.09 ± 2.03 mmol/L, t=1.911), 2hPG (9.27 ± 2.03 mmol/L vs. 12.06 ± 3.54 mmol/L, t=1.946), HbAlc (6.98%± 1.58%vs. 8.06% ± 2.13%, t=2.013) were decreasd (P<0.05). Besides, VEGF (684.61 ± 84.37 ng/L vs. 514.28 ± 79.52 ng/L, t=2.136), NO (43.28 ± 6.40 ng/L vs. 34.64 ± 6.70 ng/L, t=2.097) of treatment group were siginificantly higher than the control group (P<0.05), while ET-1 (53.13 ± 7.24μmol/L vs. 60.09 ± 7.18μmol/L, t=2.271) were siginificantly lower (P<0.05). Conclusion Tongxinluo capsule combined with Jinlida sintervention could decreased the level Blood glucose and improve vascular endothelial fuction in the patients with Type 2 diabetes.

[Objective]To improve the teaching quality ofMeridians and Acupoints. [Methods]Based on the ten-year experience of teaching the course ofMeridians and Acupoints, the authors suggest three issues on how to study well with this subject. [Results] The first, using the comparing method to remember meridians and acupoints, always do analysis and summary are all important ways to learn the basic knowledge.The second, understanding the property of acupoints, make prescription of acupoints like the way of making Chinese herbal formula according to syndrome differentiation, can cultivate students' dialectical thinking and improve the ability of diagnosis and treatment in acupuncture clinic.The third, introducing the origin,history and development of each meridian and some special acupoints. [Conclusion]The above three suggestions can help students to learn better about the science of acupuncture,and improve their professional thinking, and mine the potential ability of innovation.

Objective: To explore the association between stress, coping style, social support and subjective well-being (SWB) of college Students. Methods: 1773 college students from 8 colleges in Guangzhou were tested with Index of Well-being Questionnaire, College Students’ Stress Scale, Simplified Coping Style Questionnaire(SCSQ) and Social Support Rating Scale (SSRS). And structural equation model (SEM) was built based on the data. Results: SEM revealed ?2/df=2.837, RMSEA=0.032, and indexes of GFI、AGFI、NFI、NNFI、CFI were all above 0.9. Stress and passive coping style had passive effect on SWB (the overall regression weights were -0.377 and -0.130 respectively). Social support and positive coping style had positive effect on SWB (the overall regression weights were 0.286 and 0.277 respectively). Conclusion: Stress, coping style and social support are important forecast variables of SWB.
