Objective The polysaccharides sulfate were extracted from three kinds of algae in-cluding porphyra tenera , Laminaria ja ponica and Sargassum fusi forme ( Harv. )Setch . in order to screen antioxidant with exploiting potential. Methods Using the assay system of DP-PH,the antioxidative activities of various extracts were studied. Results Three kinds of algae polysaccharides sulfate had different antioxidative activities. Moreover, polysaccharide extracted with different solvents had different intensities of antioxidative activity. Conclusion Polysacchride sulfate extracted with water has stronger antioxidative activity than that with others.keywolds antioxidation; porphyra tenera kjellm. ; Laminaria japonica; Sargassum fusi -forme ( Harv. )Setch.Studies on the extraction of polysaccharides sulfate from three algae and their scavenging activity on free radicalsHAN Hua,ZHOU Hai Yan,LIU Cheng-Chu,WANG Chun-bo(1.Bromatology Institute of Shanhai Aquatic University , Shanghai 200090, China; 2.

Objective The antioxidative activities of extracts from Undaria pinnatifida in vitrowere tested. Methods Using the assay system of peroxide value (POV), diphenyl picryl-hydrazyl (DPPH), the antioxidative activities of various extracts were studied and comparedwith VE and VC. Results Different extracts from Undaria pinnatifida showed antioxidativeactivities, and petroleum ether extract showed the highest free radical scavenging efficiency.Conclusion petroleum ether extract has stronger antioxidative effect than others.

Objective To observe the effect of multiple interventions on secondary epilepsy patients.Methods 114 secondary epilepsy patients were randomly divided into the intervention group and control group with 57 cases in each group.The cases in the intervention group received multiple interventions including heath education,psychological treatment,safety nursing,overdose administration,early rehabilitation,discharge guide and so on besides usual nursing.While,the cases in the control group received usual nursing.The follow-up was performed for 6 months and the therapeutic efficacy of two groups was compared.Results After multiple interventions,the seizure frequency and trauma incidence rate decreased,compliance and quality of life increased in patients of the intervention group,and there was a significant difference compared with the control group(P<0.05).Conclusion Multiple interventions can decrease seizure frequency and increase compliance of treatment and quality of life of secondary epilepsy patients.

Objective To investigate effective methodology for preventing infectious diseases from spreading within general hospitals at all levels. Methods Six hospitals at three levels in the city were made into two groups and investigated for their treatment of infectious diseases. The group of A1, A2 and A3 hospitals employs the five pre-triage, while the group of B2, B2 and B3 employs the routine pretriage. Results Comparison of undetected infectious cases between group A1, A2, A3 and group B1,B2,B3 identified significant difference with x2 testing, P＜0. 005. Conclusion Five pre-triage method can screen, identify and pinpoint confirmed or suspected infectious disease patients from all outpatients in the first time, thus preventing and controlling the nosocornial transmission of epidemic or even an outbreak of nosocomial infection effectively.

AIM: To evaluate the effect of endothelial Rho and Rho kinase in extravasation migration of sarcoma cell. METHODS: We used an in vitro model of sarcoma cell transmigration across a monolayer of HUVEC cultured on collagen gel to observe extravasation migration of sarcoma cells and calculated the electrical resistance of HUVEC monolayer in extravasation migration of sarcoma cells. RESULTS: Sarcoma cells migrated through endothelial cells into collagen gel, the electrical resistance of a HUVEC monolayer reduced in extravasation migration of sarcoma cells.Endothelial Rho inhibitor(C3 transferase) and Rho kinase inhibitor(Y-27632) inhibited extravasation migration of sarcoma cells and inhibited reduction of electrical resistance of a HUVEC monolayer in extravasation migration of sarcoma cells. CONCLUSION: Endothelial Rho and Rho kinase regulates sarcoma cell transendothelial migration through modification of endothelial cytoskeleton.
