Problem-based learning(PBL)is an important part of creative education in medical colleges.Choice and design of cases are of the vital importance to success or failure of PBL course.To enhance students' ability of independent,creative thinking,and their ability of analyzing and solving problems,the roles of primitive cases and model cases as well as interrelation between them were discussed respective- ly.Moreover,five basic principles to be followed in model case design for PBL in Medical Microbiology and Human Parasitology,i.e.objec- tivity,flexibility,consistency,illumination and relevance,were proposed in this study.

OBJECTIVETo explore the therapeutic effect of qi benefiting blood activating method (QB-BAM) on acute exacerbation of chronic obstructive pulmonary disease (AECOPD) patients with blood stasis syndrome (BSS) by observing its effect on plasma fibrinogen (Fg) and D-dimer (D-D) levels.
METHODSSixty AECOPD patients with BSS were randomly assigned to the treated group and the control group, 30 in each group. All patients received conventional therapy for AECOPD. Those in the treated group were additionally injected with Shengmai Injection and Tanshinone IIA Injection. Clinical efficacy and indices including levels of Fg, D-D, PaO2, and PaCO2 were measured and compared before and after treatment.
RESULTSThe effective rate was 93.3% (28/30 cases) in the treated group, higher than that of the control group [73.3% (22/30 cases) , P < 0.05]. There was no significant difference in all indices between the treated group and the control group before treatment (P >0.05). After treatment all indices were significantly improved in the two groups (P < 0.01). But in the treated group levels of Fg and D-D decreased more and levels of PaO2 increased more (P < 0.01). Plasma levels of Fg and D-D levels were negatively correlated with PaO2 (r = -0.493, r = -0.438, P < 0.01) before treatment, and also negatively correlated with PaO2 (r = -0.452, r = -0.325, P < 0.01, P < 0.05) after treatment, but they were not significantly correlated with PaCO2 before and after treatment (P >0.05).
CONCLUSIONSQBBAM could play a therapeutic role in improving prethrombotic states of AECOPD patients with BSS. Plasma levels of Fg and D-D were related to the severity of AECOPD.

Rutaecarpine (Rut) is a type of indole quinazoline alkaloid exracted from Ruticarpum. Studies showed that Rut has a wide range of pharmacological effects, such as anti-hypertension, anticancer, anti-inflammation, anti-thrombus formation. Currently, many scholars are committed to developing it into a new antihypertensive and anti-inflammatory drug with all new mechanisms. But studies found that Rut is a highly fat-soluble drug with low water and oil solubility. Its high insolubility is the main obstacle in its oral absorption and application, which greatly reduced its bioavailability. Therefore, hydroxypropyl-beta-cyclodextrin (HP-beta-CD) was used as the inclusion material to prepare Rut-HP-beta-CD inclusion complex in this experiment, in order to increase its water solubility and bioavailability. In this experiment, the inclusion complex was prepared by the stirring-freeze-dry method. The preparation process was optimized by the orthogonal test, with the inclusion rate as the index, and molar ratio between host and guest molecules, inclusion temperature, time and stirring speed as the impacting factors. Moreover, the inclusion complex was verified by detecting the apparent solubility, thin layer chromatography, microscopic identification, melting point detection and dissolution study. The results showed that under the conditions of the molar ratio between Rut and HP-beta-CD of 1: 1, temperature at 60 degrees C, inclusion time of 4h and stirring speed at 600 r x min(-1), the inclusion rate of Rut-HP-beta-CD reached 91.04%. Therefore, the preparation process of Rut-HP-beta-CD inclusion under the optimum conditions is simple and feasible, with a highest inclusion rate and reproducibility, and could significantly improve Rut's solubility and bioavailability, and provide a reliable experimental basis for its clinical application.

Pestalotiopsis photiniae is one of the predominant pathogens of strawberry root rot disease. Based on preliminary research, it was proved that crude toxins were main pathogenic substances of the pathogen. For further investigation and utilization of toxins produced by this fungus, conditions of producing toxins were analyzed with the leaf disk method in this experiment. The result showed that pH values, cultural time, vibration, and tested temperatures obviously affected the production of toxins, except for light treatment. The most suitable culture conditions for the toxin production were pH 6.2, 25?C, darkness and stillness, for 5 d~7 d. Besides, it was discovered that crude toxins could significantly inhibit seed germination and elongation growth of roots or shoots for maize, rye and mung bean.
