Objective:To study the effect of portal vein occlusion on intestinal mucosal barrier in rats and the protection of ulinastatin to the injury,to present the experimental data for the clinical surgery.Methods:70 Sprague-Dawley rats were randomly divided into controlled group (n=10),operation group (n=30) and operation+medication group (n=30).The portal vein were occlused 40 min in the operation groups and operation+medication groups.2ml blood from portal vein,lymph nodes around appendix,1cm small intestine wall were taken for endotoxin levels,bacterial translocation and pathiology examinations in the all rats 280 mins after operation.The mocusal barrier and microscopic structure of intestine were observed.Results:Compared between the control group and the operation group,endotoxin levels,bacterial translocation rates rise greatly and gut structure change obviously in the latter.Compared between the operation group and operation+medication group,the former changes is also obvious.Conclusion:The occlusion of portal vein can leads the decrease of intestine mocusal barrier and the increase of its permeability.Ulinastatin has a good protective effect on the damages above.

OBJECTIVE:To provide reference for further development of Internet drug transaction services in China. METH-ODS:The data of online drugstores with top 20 approvals data and sales amount were collected bu the Internet,the normative man-agement was evaluated. Meanwhile,questionnaire was conducted to survey and analyze the cognition,buying drugs and correspond-ing requirements of some Shanghai citizens for Internet drug retail. RESULTS:By Jun. 12,2015,totally 307 retail chain drug-stores(online drugstores)had got the License of Internet Drugs Transaction,only 62 online drugstores(20.2%)were in full compli-ance with the normative management;the top 19 online drugstores supplied averagely 1 072±815 OTC medicines,including 259± 165 chemical drugs and 813 ± 650 Chinese traditional medicines,and the top 3 were jianke.com (3 658 species),J1.com (2 071 species)and 360 kad.com(1 523 species). Totally 216 questionnaires were sent out,and 183 were effectively received with effec-tive recovery of 84.7%. The 183 surveyed citizens showed high cognition in distinguishing the authenticity of online drugstores (75.4%) and the authenticity of drugs (67.1%),but low cognition in online drugstore opening qualifications and Internet selling drugs;only 22.4% had the experience of buying drugs online,the degree of satisfaction towards online shopping,from the highest to the lowest,were drug price(62.5%),professional consultation of pharmacists(50.0%),variety of drugs(45.0%),quality of drugs(37.5%),delivery time(35.0%),etc.;the most probably purchased medicine category were vitamins and minerals(63.9%) and medicines for common diseases(40.4%). CONCLUSIONS:Currently the demands and confidence of online drugs shopping of Shanghai citizens are still scarce. Though the access of retailing prescription drugs would spur the Internet drug business,the condi-tion is still immature. It is suggested to sell prescription drugs in a limited way and improve their access threshold,promote Medi-care settlement to multi-faceted promote the orderly development of Internet drug transaction services.

Objective To investigate the prevalence of healthcare-associated infection(HAI)in medical institutions in Pudong New Area.Methods Ten medical institutions in Pudong New Area were selected as monitored hospitals, cross-sectional survey on HAI in each hospital at a given day of November 2013 and November 2014 were conduc-ted.Prevalence of HAI in different levels of hospitals were compared.Results The prevalence rates of HAI in 2013 and 2014 were 4.04% and 3.75% respectively,there was no significant difference between two years(χ2 =0.709,P=0.400).The prevalence rates of HAI in primary,secondary,and tertiary hospitals in 2013 were 0.66%,3.32%, and 4.60% respectively,in 2014 were 0,3.52%,and 4.01 % respectively,prevalence rates of HAI in different lev-els of hospitals of each year were significantly different (all P <0.05).Prevalence rates of HAI were high in depart-ments of neurosurgery,hematology,intensive care units(ICUs),and gerontology.The prevalence rate of infection in ICUs increased obviously,from 10.09% to 18.78% (χ2 =3.921 ,P =0.048),departments of gerontology de-creased obviously,from 10.07% to 5.02%(χ2 =5.698,P =0.017).The main HAI sites were lower respiratory tract (36.72%),upper respiratory tract (9.96%),and urinary tract (12.89%).172 pathogenic isolates were de-tected in 2013,and 177 were detected in 2014,gram-negative bacteria,gram-positive bacteria,and fungi accounted for 60.74%,26.37%,and 12.89% respectively.Constituent ratios of pathogens causing HAI between two surveys were not significantly different (χ2 =5.819,P =0.830).Conclusion Among different levels of hospitals in Pudong New Area,tertiary hospitals have the highest prevalence rate,HAI in ICU increases obviously,the main HAI site is lower respiratory tract,the main pathogens are gram-negative bacteria.

Objective To identify the risk factors for severe acute lower respiratory infections (ALRI) in children and to provide scientific basis for prevention and treatment of ALRI. Methods Several databases including Pubmed, Databases-Medline (Ovid), Embase, CINAHL and Global Health Library, CNKI, VIP and Wanfang Date were searched (1990.1-2014.12) for references. All selected studies were about risk factors of ALRI in children. The screening and quality evalua? tion of the literature data was conducted independently by two reviewers according to the inclusion and exclusion criteria. Stata 11.0 software was used for Meta-analysis. Results Meta-analysis of 27 included literature showed that seven risk fac?tors were significantly associated with severe ALRI:low birth weight, lack of exclusive breastfeeding, crowded household, ex?posure to indoor air pollution, malnutrition, living in a house with smokers or smoking in pregnant and HIV-exposed unin?fected condition. Conclusion The above seven risk factors play the important role in the development of ALRI in children. Furthermore, it emphasizes the need for further studies investigating other potential risk factors to decrease the possibility of childhood ALRI.

AIM To investigate the effects of Tongluo Xingnao Effervescent Tablets (Chuanxiong Rhizoma,Angelicae sinensis Radix and Scutellariae Radix) on the learning and memory function in SAMP8 mice,and improvements in cognitive function.METHODS Morris water maze was used to evaluate the change of cognitive function in SAMP8 mice after they were treated with Tongluo Xingnao Effervescent Tablets for 60 d,and the activity of superoxide dismutase (SOD),the concentration of protein carbonyls (PC),the ratio of NAD +/NADH in brain tissue were detected by ELISA,the expression of Nampt,SIRT1 and FOXO3 in hippocampus were measured with immunohistochemical methods.RESULTS Tongluo Xingnao Effervescent Tablets shortened escape latency and obviously increased percentage of time in target quadrant in hidden platform test and increased the times entering the target quadrant in spatial probe test in SAMP8 mice.It evidently enhanced the activity of SOD,the ratio of NAD +/NADH and distinctly decreased the protein carbonyls level.Moreover,Tongluo Xingnao Effervescent Tablets could markedly up-regulate the expression of Nampt and SIRT1,but evidently down-regulate FOXO3 protein expression.CONCLUSION The experimental data show that Tongluo Xingnao Effervescent Tablets can enhance the cognitive function of SAMP8 through regulating Nampt/SIRT1/FOXO3 signal pathway.

Objective To explore a better method to diagnose the brachial plexus injury as pre-or post-ganglionic,which is quick,simple,quantitative,cheap and accurate.Methods Forty-five SD rats were divided randomly ino pre-or post-ganglionic brachial plexus injury models group,and the choline acetyl- transferase(CHAT)activity was detected by using the radioisotope after different days.Results The ChAT activity of two groups both fall day by day:in the pre-agnglionic group,it falls quickly,and reach 1/10 of nor- mal(675?258)cpm;in the post-ganglionic group,it falls slowly,and reach 1/2 of normal even after 90 days (4906?1119)cpm.Conclusion Intra-operative measure of ChAT can be used to differentiate pre-or post- ganglionic brachial plexus injury.
