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 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.

Objective To establish an HPLC method for the determination of isopimaric acid in the leaves of Platycladus orientalis and its preparations Cebai No.V Capsula and Isopimaric Acid Capsula to evaluate the quality of them. Methods HPLC Method was developed. Kromasil C18(200 mm?4.6 mm, 5 ?m) column was used and the mobile phase: methyl alcohol-water-acetic acid (60∶37∶3), float rate: 1 mL/min, temperature: 25 ℃, wavelength: 231 nm, injected volume: 10 ?L. Content of isopimaric acid in samples was calculated by external standard. Results The linearity relationship of isopimaric acid was good in the range of 1.25-10.00 ?g. The equation of standard curve: Y=66 214 X+2 487.9, r=1.000. The average recovery was 95.8%, RSD=2.7% (n=5). The determination results of isopimaric acid in three batches of P. orientalis were 3.09, 3.20, and 3.56 mg/g; three batches of Cebai No.V Capsula were 10.39, 9.67, and 10.99 mg/g; three batches of Isopimaric Acid Capsula were 553.89, 541.50, and 528.83 mg/g. Conclusion The method is reliable, simple, and precise, which could be used for the quality control of P. orientalis and its capsules.

[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.

0.05).The medical expenses of the Hysteroscopic Group was significantly lower than that of the Laparoscopic Group(t=-85.584,P=0.000).Conclusions As compared with laparoscopic conservative operation,hysteroscopic tubal catheterization with MTX injection is another simple,cost-effective,and minimally invasive alternative for early tubal pregnancy.

Objective:To construct a recombination plasmid containing a kanamycin resistance gene,the upstream and downstream fragment of luxS of Streptococcus mutans so that luxS can be knock out by transforming the plasmid into S.mutans later.Methods:Kanamycin resistance gene,the upstream and downstream of luxS were cloned respectively by using plasmid pEGFP-N1 and DNA of Streptococcus mutans as template.Then the genes were ligated into Multiple Cloning Site(MCS) of vector pMD19-T in certain order and transformed into E.coli Competent Cells.Finally transformants were selected for resistance to kanamycin and ampicillin.Results:Kanamycin resistance gene and the upstream and downstream of luxS were successfully ligated into accurate enzyme digestion site of vector pMD19-T,and restriction digests analysis and sequencing result was correct.Conclusion:LuxS gene knock-out of Streptococcus Mutans recombinant plasmid is constructed and built a base of constructing Streptococcus Mutans luxS mutans in the future.

OBJECTIVE:To prepare tamsulosin hydrochloride sustained-released tablets and to investigate the in vitro drug release feature and mechanism of the tablets.METHODS:Tamsulosin hydrochloride sustained-released tablets were prepared with HPMC as matrix.The effects of multiple factors on the in vitro drug release rate were evaluated with accumulative release rate as index,and the slow release feature was compared between the sustained tablets and the common tablets.RESULTS:The drug release rate was predominantly influenced by the amount of HPMC and the tablet compressing pressure,and the optimum values of the two were 25% and 8kg～11kg,respectively.The accumulative release rates of the sustained tablets and the common tablets at 0.5h were 10% and 50%,respectively.CONCLUSIONS:The sustained-release tablets had a better sustained release efficacy as compared with common tablets,and the drug release feature of the sustained tablets was the synergistic action of the tamsulosin hydrochloride diffusion and matrix degradation and the release pattern obeyed non-Fick diffusion mechanism.
