The medical care reform is at the stage of rapid development of economic,science and technology in China. Facing the problems and the reform trend of focusing on the hospitals at basic level for medical services,medical schools should play the role in training medical personnel for community and township. The pathways for cultivating the applicable medical talents include the scale enlargement and structure adjustment,quality control,curriculum reform,postgraduate education and training program on post.

Problem-based Learning (PBL) has become a curriculum model in medical education. The paper expounds its emergence and development, concept, characteristics of learning, fundamental teaching process, problem designing, advantages and disadvantages, and features of curriculum contents.

Pharmacognosy (Chinese Medicine) discipline has a long history and International cooperation is more and more frequent, but the communication of the Chinese traditional medicine cul-ture is very difficult. In order to solve this problem, it is urgent to improve the professional English level of the students. Thus, combined with the education survey and interview results, as well as the reports in previous studies and our own experience, we think about how to set pharmaceutical profes-sional English course and put forward some suggestions such as the innovation of curriculum organiza-tion strategy, convergence of basic English course, teaching content and form being closely linked to academic activities, and paying attention to highlighting the subject characteristics of pharmacognosy (Pharmacy).

Objective: To investigate the effect of gastrodin against oxidative stress induced by high glucose in human umbilical vein endothelial cells (HUVEC). Methods: Primary HUVEC were isolated and cultured, then the oxidative injury model of HUVEC was established by high glucose, and the cells were treated with different concentration of gastrodin. The cell viability of HUVEC, nitric oxide (NO) content, superoxide dismutase (SOD) and catalase (CAT) activities, total anti-oxidative capacity (T-AOC), malondialdehyde (MDA) content, and intracellular reactive oxygen species (ROS) level were determined. Furthermore, the expression of NF-κB mRNA in HUVEC was also detected by real-time fluorescent quantitative PCR. Results: Compared with the control group, the oxidative stress was strengthened obviously in cells treated with high glucose. However, gastrodin could increase the activity of SOD and CAT and enhance T-AOC in HUVEC. Meanwhile, the amounts of MDA and ROS were decreased, and the level of NF-κB mRNA was also reduced markedly. Conclusion: These results indicate that gastrodin could inhibit the oxidative stress in HUVEC by enhancing the activity of anti-oxidative enzyme, and decreasing the amounts of lipid peroxidation products and ROS. The mechanism may be involved in NF-κB pathway.

Traditional Chinese medicine (TCM) contains a big array of chemical constituents. These constituents un-dergo various metabolic reactions to produce complex in v iv o metabolites. Identification and distribution of these metabolites are important to reveal the effective constituents from a complex formulation. Recently, developments had been made to elucidate the complex metabolic process. In this review, we summarized the methods and strategies developed for TCM metabolism. Application of these metabolic results has also been discussed.

Objective To investigate whether insulin resistance is a cause of pregnancy induced hypertension (PIH). Methods All patients who had abnormal 50g glucose screening test accepted 75g oral glucose tolerance test (OGTT) and insulin sensitive index (ISI) was calculated. These patients were followed up and divided into two groups (PIH group and normal pregnancy group) at third trimester of pregnancy. The difference of ISI between the PIH group and normal pregnancy group was compared. Results Fast blood glucose, fast blood insulin and ISI were (4.2?0.7)mmol/L vs. (3.8?0.7)mmol/L, (107.8?48.8)pmol/L vs. (50.4?40.5)pmol/L, and -3.25?0.27 vs. -2.58?0.66 in PIH group and normal group, respectively ( P 0.05). Conclusions Insulin resistance during second trimester of pregnancy may be one of the causes of pregnancy induced hypertension.

Objective To establish a RP-HPLC method to determine the content of geniposide in Xiaoyan Tuire Patch. Method The column of Agilent ZORBAX SB-C18 (4.6 mm?250 mm 5 ?m) was used. The mobile phase was composed of water-acetonitrile-phosphoric acid (86∶14∶0.01). The flow rate was 1 mL/min, with UV detection at 238 nm, and the temperature was 30 ℃. Results The linear range was 0.07～0.70 ?g (r =0.99997). The average recovery was 98.60% and the RSD was 1.96%. Conclusion The method is simple, sensitive and accurate, and can be used for the determination of Xiaoyan Tuire Patch.
