Objective To investigate the influence of atosiban on the pregnancy outcome in patients with repeated implantation failure(RIF)in blastcyst thawed embryo transfer(bTET) Methods From January 2014 to December 2015,a total of 262 RIF patients undergoing bTET were retrospectively studied. They were divided into study group with a single bolus dose (6.75 mg/0.9 mL,iv) of atosiban before bTET (n = 94),and control groupwithout atosiban(n = 168). Results The clinical pregnancy rate(57.41%),implantation rate(38.41%) and living-birth rate(46.81%) of study group were significantly higher than those of control group (41.12%, 28.32% and 33.93% respectively;P < 0.05). Although the abortion rate of study group was higher than that of control group(14.82% vs 13.04%),both the ectopic pregnancy rate(3.70%) and the multiple pregnancy rate (16.67%) were lower than those of control group(5.79% and 17.39%),and there was no statistical difference (P > 0.05). Conclusion Atosiban treatment before embryo transfer may improve pregnancy outcomes of RIF patients in bTET.

In order to study the regularity of shedding virus from infected SPF chickens and the formation of aerosol of H9N2 subtype AIV, SPF chickens were bred in a positive and negative pressure isolator. Aerosol samples were collected by AGI-30 (All Glass Impinger-30) extractor, and simultaneously trachea and cloaca samples were collected by tracheal swabs and cloacal swabs in different periods after challenged with vi- ruses. The above-mentioned samples were detected by HI, Dot-ELISA and RT-PCR methods. The results in- dicated that aerosols were isolated from the 4 days to the 43 days after inoculation. It was proved that H9N2 subtype AIV could copy themselves in respiratory passage and cloaca, and then could formation of aerosols. AIV H9N2 subtype could be isolated from cloacal and tracheal swabs 3 days after inoculation and lasted for 45 days, viruses were detected from all infected SPF chickens on 7 days.

The aim of this study is to investigate absorption-promoting mechanism of enhancers and the transport pathway of large hydrophilous molecular across rat nasal epithelium by electron spin resonance (ESR) and confocal laser scanning microscopy (CLSM) technologies. In the experiment, recombinant hirudin-2 (rHV2) was chosen as a large hydrophilic molecular model drug. After nasal administration in rats the bioavailability of rHV2 with or without various enhancers was compared. The effects of enhancers on membrane lipid fluidity and protein conformation were measured with 5-deoxyl-stearic acid (5-DSA), 16-deoxyl-stearic acid (16-DSA) and 3-maleidoproxyl (MSL) labeling ESR. The effects of enhancers on cytoskeletal F-actin of rat nasal epithelium and FITC-rHV2 transport pathway across rat nasal epithelium were performed by CLSM combined with fluorescence labeling. 0.5% Chitosan (CS), 5% hydroxyl-propyl-beta-cyclodextrin ( HP-beta-CD) and 1% ammonium glycyrrhizinate (AMGZ) were all able to significantly increase the nasal absorption of rHV2. CS could result in the paracellular pathway transport of FITC-rHV2 which seemed related to a transient effect on tight junctions. HP-beta-CD could cause paracellular and transcellular route transport of FITC-rHV2 by influencing upon membrane protein as well as lipid fluidity. AMGZ seemed to enhance the transcellular route transport of FITC-rHV2, and could exert some influence on membrane protein but not on lipid fluidity. So how it brought out this result needs further research. Present experiment may become a useful reference for promoting mechanism of enhancers and the transport pathway of large hydrophilic molecular across nasal epithelium research.

OBJECTIVETo explore the effects of integrative medicine (IM) rehabilitation protocolon motor function, activity of daily living, and quality of life (QOL) in hemiplegia patients after stroke.

METHODSTotally 120 patients with post-stroke hemiplegia were allocated to four groups using sealed envalope drawing, i.e., the rehabilitation group, the Chinese medical treatment group, the acupuncture group, and the comprehensive rehabilitation group, 30 cases in each group. Based on routine rehabilitative training, patients in the Chinese medical treatment group, the acupuncture group, and the compre-hensive rehabilitation group received standardized treatment based on syndrome typing, Shi's Consciousness-Restoring Resuscitation acupuncture, Chinese herbs + acupuncture comprehensive rehabilitatino protocol, respectively. The treatmet cycle consisted of 4 weeks with 24-week follow-ups. Fugl-Meyer motor assessment (FMA), Modified Barthel Index (MBI), and Stroke-Specific Quality of Life Scale(SS-QQL), and safety assessment were taken as main effect indices before treatment, at week 4 of treatment, at week 12 and 24 of follow-ups, respectively.

RESULTSThere was no statistical difference in FMA score, MBI score, SS-QOL score among the four groups before treatment (P > 0.05). These scores were significantly improved in the four groups at week 4 of treatment, week 12 and 24 of follow-ups, respectively (P < 0.05). Besides, FMA score and SS-QOL score were significantly improved in the comprehensive rehabilitation group at each corresponding time point, as compared with other treatment groups (P < 0.05).

CONCLUSIONSThe comprehensive protocol could significantly improve motor function, activity of daily living in hemiplegia patients after stroke, and further improve their QOL. Its effect was better than other single treatment.
