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.

Objective To discuss incidence and related risk factors of vascular cognitive impairment (VCI) after acute subcortical infarction (SI).Methods One hundred and eighty-two patients with acute SI were divided into two groups:VCI group (81 cases) and no-VCI group ( 101 cases) according to VCI diagnostic standard.Sex proportion,age,culture degree between two groups were compared,and correlation was analyzed between the quantity of risk factors and the incidence of VCI.Results The incidence of VCI after acute SI was 44.5％(81/182).According to age stratification,the incidence of VCI in the patients of 56-65 years was 35.4％ (23/65),in the patients of 66-75 years was 45.3％ (48/106),and in the patients of 76-85 years was 90.9％ (10/11 ).The age in VCI group was significantly higher than that in no-VCI group [(69.93 ±6.91) years vs. (67.62 ±5.56) years,P =0.014],and culture degree was significantly lower than that in no-VCI group (P =0.028).The sex proportion between two groups had no significant difference (P =0.876).The more accompanying risk factors,the higher incidence of VCI.Conclusions Along with the increase of age,the incidence of VCI after acute SI is higher.The more accompanying risk factors,the higher incidence of VCI.

Objective To explore the relationship of coping style and social support with hope in maintenance hemodialysis patients.Methods A total of 177 maintenance hemodialysis patients were recruited from 3 dialysis centers in Guangzhou and were investigated with the self-designed questionnaire,the Herth Hope Scale,Simplified Coping Scale and Social Support Scale.Structural equation model was used to establish the model of relationship of coping style and social support with hope level.Results The average score of hope in maintenance hemodialysis patients was (31.83±3.69) points.The total score and all the sub-scores of social support were (42.24±4.09) points,(23.72±2.36) points,(10.82±2.26) points,(7.70±1.36) points respectively.And the average scores of positive coping style and the negative coping style were (2.15±0.28) points,(1.56±0.33) points,respectively.Social support had direct positive effect on hope level,and the positive and neg-ative coping style had indirect positive and negative effect on hope level respectively.Conclusions Social support has a direct effects on hope level in maintenance hemodialysis patients.Positive and negative cop-ing styles have indirect effects on hope level through social support.

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.

To investigate the correlation between traditional Chinese medicine (TCM) syndrome and short-term prognosis of ischemic stroke.

OBJECTIVE: To obtain sustained-release indomethacin PLGA/Eudragit RS 100 microspheres for ophthalmic application and to evaluate its quality. METHODS: The microspheres were prepared by O/W solvent evaporation using PLGA and Eudragit RS 100. The morphological, drug content, entrapment efficiency, release behavior, particle size, residual organic solvent, Zeta potential of indomethacin PLGA/Eudragit RS 100 microspheres were determined; meanwhile, the cytotoxicity of blank microspheres was evaluated using PRE cells. RESULTS: Indomethacin microspheres containing PLGA and Eudragit RS 100 at the weight ratio of 1: 3 had even particle size distribution, and their surfaces were smooth under scan electronic microscope; and the mean diameters were (1676.4 ± 739.5) nm. The drug content and entrapment efficiency of the microspheres were (18.79 ± 0.19)% and (98.25 ± 2.11)%, respectively. Indomethacin was released slowly for a month from the microspheres, though burst release was observed within 24 h. The mean residual organic solvent was (267.33 ± 13.57) ppm. The zeta potential of all blank PLGA / Eudragit RS 100 microspheres was positive. The blank microspheres showed no sign of toxicity. CONCLUSION: Indomethacin PLGA / Eudragit RS 100 microspheres have a better clinical application prospect due to its high entrapment efficiency, narrow distribution, slow release and ocular safety.
