OBJECTIVE: To observation the effects of Glycosaminoglycan from Scallop Skirt (SS-GAG) on the production of vasoactive substance in the endothelial cells injured by hydrogen peroxide(H2O2). METHODS: In H2O2-induced en-dothelial cell oxidative damage model group which was established with human umbilical vein endothelial cell (HUVEC, ECV304) cultured in vitro, SS-GAG groups (at different concentrations) and the normal group, levels of 6-keto-PGF1a, Thromboxane-B2 and Endothelin (ET) in the culture fluid were detected by radioimmunity assay and the content of nitric oxide was determined by nitrate reductase method. RESULTS: As compared with model group, SS-GAG (at different concentrations) significantly enhanced the levels of 6-keto-PGF1a and NO but significantly decreased levels of TXB2 and ET (P

AIM:To establish a fingerprint method of analyzing Xuefu Zhuyu Capsule(Semen Persicae,Radix Angelicae sinensis,Fruclus Aurantii,Rhizoma Chuanxiong,etc.) by HPLC. METHODS: A HPLC in combination with PDA detector was applied with a HiQ C_(18)(4.6 mm?250 mm,5 ?m) column by gradient elution using methanol-1.0% acetic acid solution as the mobile phase.The flow rate was 0.5 mL/min and the detection wavelength was at 260 nm. RESULTS: Thitrty-six common peaks were obtained in the fingerprint of Xuefu Zhuyu Capsule with good separation,six of them were identified as adenosine,paeoniflorin,naringin,hesperidin,neohesperidin and ligustilide by comparing chromatogram with control compounds. CONCLUSION: The HPLC method with good precision and reproducibility can be used for the quality control of Xuefu Zhuyu Capsule.

It is essentially indispensable to use multimedia methods in teaching "Clinical Medicine Outline". Such usage can diversify the teaching approaches and play a very important role in improving teaching methods and deepening students’ comprehension of course knowledge. Some problems existing in application of multimedia in the teaching process need to be settled.

0.05).Conclusion The isotonic contrast medium has litter effect on the renal function of the patients with high risk factors.

Hospital information management has penetrated into each aspect of hospital management.We discussed briefly the role of the hospital information system in medical records management in Chinese medicine hospital on information sharing,data statistics and convenience of case consulting and management,which improved greatly the efficiency of medical records management.

Many datas show that thrombosis related events during chemotherapy in patients with cancer increase obviously.Thromboprophylaxis in patients receiving chemotherapy has been shown to not only improve the hypercoagulable states and effectively prevent thrombosis,but also have the potential antitumor effect and prolong the patients over survival.

Objective: To establish the quality control standard for Xiaozhi Solution(Radix et Rhizoma Rhei, Radix Scutellariae, Radix Paeoniae Rubra, Rhizoma Smilacis Glabrae, etc.) Methods: Radix et Rhizoma Rhei Radix Scutellariae、 and Radix Paeoniae Rubra in solution were identified by TLC. The contents of emodin chrysophanol were determined by HPLC. The average recovery of added sample were 99.10% ( RSD was 1.88% ) for emodin and 98.87% ( RSD was 1.21%) for chrysophanol. Results: The method was simple, accurate and specific. Conclusion: The method can be used for the quality control of Xiaozhi Solution.

Objective: The experiment was undertaken to explore the blood-brain barrier permeability and the gene expression of matrix metalloproteinase-9 (MMP-9) in ischemic cerebra and the impact of Buyanghuanwu Decoction on them. Methods: The (middle cerebral artery occlusion, MCAO) rat model was used. At 1h, 3h, 24h, 48h, 5d after reperfusion. They were measured. Results: In treatment group, the BBB permeability and the MMP-9 gene expression decreased. Conclusion: Buyanghuanwu Decoction can protect the BBB by inhibiting the MMP-9 gene expression.

Objective: To study the effect of ?- carotene(?-C) on lipid peroxidation and RBC-membrane fluidity of rats inflicted with alloxan. Methods: Forty-four 2mo-old Wistar rats were randomly divided into 4 groups and fed with basal diet (group A and B), basal diet + vitamin E (200 mg/kg) (C) and basal diet+? carotene (200 mg/kg) (D) for 4 w respectively. Then, alloxon (3%) was injected intraperitoneally except group A, which was injected with normal saline. After 48 h the rats were killed and a series of indices were examined. Results: After injected with alloxan, Na +,K +-ATPase and GSH-Px activity, RBC-membrane fluidity in rats fed with diets C,D were markedly increased while MDA levels were decreased. Conclusion: ?-C and V E can decrease lipid peroxidation and increase the stability of RBC-membrane in rats inflicted with alloxan.
