Objective:To observe the effects of acupuncture at the follicular phase on ovarian blood supply and pregnancy outcomes in patients who received in vitro fertilization/intracytoplasmic sperm injection-embry transfer (IVF/ICSI-ET) of assisted reproductive technology (ART).Methods:A total of 169 IVF/ICSI-ET female recipients from the Reproductive Center of Xiehe Hospital,Tongji Medical College,Huazhong University of Science & Technology were randomized into an observation group (57 cases),a placebo group (54 cases) and a control group (58 cases).The observation group received acupuncture during the follicular phase,meanwhile the placebo group received placebo-acupuncture,and the control group did not receive acupuncture.The hemodynamic index,biochemical pregnancy rate and clinical pregnancy rate of each group were observed,respectively.Results:As to the ovarian arterial hemodynamic index,the pulsatility index (PI),resistance index (RI),and the systolic-to-diastolic peak velocity ratio (S/D) of the observation group were (0.819±0.131),(0.552±0.055) and (2.306±0.512),respectively,obviously lower than those in the placebo group and the control group,and the differences were statistically significant (all P<0.05),but there were no statistically significant differences between the placebo group and the control group (all P>0.05).As to the biochemical pregnancy rate and clinical pregnancy rate,the biochemical pregnancy rate in the observation group was 64.9% and the clinical pregnancy rate was 52.6%,which were significantly higher than those in the placebo group and the control group,and the differences were statistically significant (all P<0.05),while there were no significant differences between the placebo group and the control group (both P>0.05).Conclusion:Acupuncture treatment during the follicular phase can improve ovarian blood supply and pregnancy rate in those receiving IVF/ICSI-ET.

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 investigate the prevalence of year-round respiratory viral infection in children with lower respiratory tract infection (LRTI), and the relationship between respiratory viral infection and allergen sensitization in exacerbating asthma. Methods A total of 231 hospitalized children with acute LRTI were investigated from May 2013 to April 2014. The 5 most common respiratory viruses were isolated from nasopharyngeal aspirate using multiplex reverse transcription-polymerase chain reaction, including respiratory syncytial virus (RSV), adenovirus (AV), parainfluenza virus (PIV), influenza virus (IFV) and rhinovirus (RV). Atopic sensitization was defined if more than 1 serum specific immunoglobulin E level measured using immunofluorescence experiment was over 0.35 IU/mL. Results RSV was the most common pathogen of bronchiolitis in hospitalized children through the year. RV or IFV infections were more prevalent in asthma exacerbations compared to other LRTIs. AV was more likely to cause pneumonia. RV and IFV were associated with asthma exacerbations in children with atopic sensitization, but not in nonatopic children. Conclusion RV and IFV are associated with hospitalization for asthma exacerbation in children with atopic sensitization.

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.

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.
