So, we start to looking for a new, more suitable way of teaching.--Project Based-on Learning, and have analyzed the advantages in health information technology teaching by construction doctrine in combination with the concept and principle in wedlock construction. At the same time we introduce project Based-on Learning in concrete application to find a way to put the theory into practice.

BACKGROUND: Research about magnetic drug microsphere has developed rapidly at home or abroad; additionally, previous studies have been focused on glucan, chitosan, and polyester as coating materials; however, gel material has been less reported,in particular gel-coating berberine microsphere has been not reported yet.OBJECTIVE: To prepare berberine magnetic gelatin drug microsphere, and to evaluate drug releasing, loading, and cross-linking using dynamic dialysis and light electron microscope.DESIGN, TIME AND SETTING: Preparation and property of microsphere were performed in Guizhou Yikang Pharmacy Co., Ltd.And Guizhou University from February 2004 to May 2006.MATERIALS: Gel, berberine, glutaraldehyde, liquid paraffin, and Fe_3O_4 were used in this study.METHODS: Magnetic microspheres of berberine drug with gelatin and Fe_3O_4 were prepared by a reverse phase suspension cold-condensation method according to biocompatibility of gel, solidification of glutaraldehyde, and disperse medium of liquid paraffin.MAIN OUTCOME MEASURES: Structure, morphology, drug-loading rate, entrapment efficiency, and in vitro releasing of drug microsphere.RESULTS: The diameter of the microsphere was under 20 urn. Scanning electron microscope demonstrated that Fe_3O_4 and berberine were compounded by gel into a round shape, and the mixture was expressed on micrometer. Ultraviolet absorption and infrared analysis suggested that berberine magnetic gelatin drug microsphere still had structure and property of raw drug. The drug-loading rate of berberine microsphere was 7.2%, the content of Fe_3O_4 was 20.8%, and the entrapment efficiency was 62.6%.the sustained-releasing ability of microsphere was well, and the releasing content counted for 83.5% of total drug within 7 hours.CONCLUSION: The berberine magnetic gelatin drug microsphere which was prepared by reverse phase suspension cold-condensation method characterizes by sample preparation, small diameter, regular morphology, and great sustained-releasing ability.

AIM: To investigate the protective mechanism of Danggui Buxue Decoction(Radix Astragali,Radix Angelieae Sinensis) on the kidney of diabetic rats. METHODS: The diabetic animal model was made by a single intraperitoneal injection of 60 mg/kg streptozotocin(STZ) and treated with Danggui Buxue Decoction(DBD) or Benazepril. Renal weight/body weight ratio, blood glucose and lipid, urinary albumin and ? 2-microglobin were measured. The renal pathological lesions were also investigated. The expression of TGF-? 1 mRNA in renal cortex as well as Angiotensin Ⅱ(AngⅡ) concentration of plasma and kidney tissue were determined by In situ hybridization and radioimmunoassay after 4,8 weeks of treatment. RESULTS:DBD had equivalent effects with Benazepril in protecting renal function and alleviating pathologic lesions. By means of inhibiting the expression of of TGF-? 1 mRNA. DBD had no effect on renal and plasmaAngⅡ. CONCLUSION:Danggui Buxue Decoction may alleviate kidney lesion and slow down the progression of DN by decreasing the renal expression of TGF-? 1 mRNA.

Lentinan could enhance the proliferative response of the mouse spleen lymphocytes to FHA, LPS ( Lipopolysaccharides ) and MLR ( Mixed Lymphocyte Reaction ) in vitro in a concentration-dependent manner. At the concentration of 25M-g/ml, it had the most prominent effects and the enhancing rates were 42.1%, 24.1% and 27.1% respectively. At much higher or lower concentrations, however, it had almost no effects. But lentinan at 25H-g/ml could inhibit the prolifera-tire response to Con A ( Concanavalin A ) and the inhibitory action increased with the increase in the concentration. At the concentration of 200 p-g/ml, the inhibition rate was 52.2%.
