Stroke is a hi-attack rate,hi-multilation rate and hi-death rate disease.More than 70 percent patients with stroke remain functional disturbance,which destroy their quality of life and bring them heavy burden.The early multidisciplinary rehabilitation treatment,rehabilitation care,family rehabilitation training and application of new technology are the major strategies in kinds of rehabilitation treatment on stroke patients.The clinical researches have showed that the effect of multidisciplinary rehabilitation treatment is obviously better than simple treatment.So these therapeutic regimens have wonderful prospect and valuable generalization.

Objective To screen and analyse the dominated related factors for medical discipline construction and development,and provide evidences for the reinforcement of discipline connotation construction.Methods The candidate medical disciplines of State Key Disciplines Evaluation of 2007 were served as study subjects.Disciplines from the results of State Key Discipline Evaluation were divided into "new discipline" group(n=51),"breeding discipline" group(n=33)and "failed discipline" group(n=81).The differences between results of State Key Discipline Evaluation and corresponding data of past years(2001 to 2006)in academic team,scientific research,graduate education and lab construction were analysed by nonparametric Kruskal-Wallis test.Results There were significant differences in academic leader,state key project,prize level,graduates quality and scientific research base among the results of State Key Discipline Evaluation(P≤0.05),and the dominated factors for the unsuccessful result were lack of high-level academic leader,state key discipline,prize,gruaduates and scientific research base.Conclusion The adoption of appropriate measures for the construction of academic team,the reinforcement of scientific research and the establishment of academic achievement evaluation may help to upgrade the academic level.

OBJECTIVETo explore effective pretreated methods for hydrosalpinx before frozen embryo transfer (FET).

METHODSA randomized controlled study was performed on 229 FET cycles of hydrosalpinx patients. They were assigned to two groups by random digit table, Group A (94 cases), Group B (89 cases), and Group C (46 cases). Patients in Group A received transvaginal aspiration of hydrosalpinx combined with auricular point sticking. Those in Group B received transvaginal aspiration of hydrosalpinx group. Those in Group C received no transvaginal aspiration of hydrosalpinx. Pregnancy outcomes of FET, endometrial and subendometrial blood flow distribution on the embryo transfer day were compared among the three groups.

RESULTSThere was no statistical difference in the endometrial thickness on FET day, the number of transfer embryos, the number of transferred good quality embryos among the three groups (P > 0.05). The clinical pregnancy rate and the embryo implantation rate were significantly higher in Group A than in Group C (P < 0.05), and the clinical pregnancy rate was significantly higher in Group A than in Group B (P < 0.05). The early abortion rate and the transfer cycle cancel rate were significantly lower in Group A than in Group C (P < 0.05). Type A endometrial and subendometrial blood flow distribution was dominant in Group A, which was significantly higher in Group A than the rest two groups (P < 0.05). Type A distribution rate was also significantly higher in Group B than in Group C (P < 0.05).

CONCLUSIONTransvaginal aspiration of hydrosalpinx combined with auricular point sticking before FET could improve the endometrial receptivity and improve outcomes of IVF.

Objective To evaluate the effects of 131 adrenoceptor anfisense on blood pressure and?1 adrenoceptor mRNA and protein levels in 2 kidney 1 clip(2K1C)rats.Method 2KIC hypertensive rots were produced by clipping renal artery of SD rats.Liposome/AS-ODNs 2.0 were tested intravenously in rats with 2KIC hypertension.Animals were divided into 5 groups(n=18 in each group):?1-AS-ODN group,?1-IN-ODN group,2K1C group,Sham group and SD group.Blood pressure was measured by tail-cuff method,the levels of myocardial?adreneceptor mRNA and protein were tested by RT-PCR and binding assay.Results On the basis of the magnitude and duration of hypotension,?1-AS-ODN decreased blood pressure by 39 mmHg at the most for 4 weeks.Compared with the 2KIC group,?1-AS-ODN did not significantly change the levels of myocardial?1 adrenoceptor mRNA but significantly decreased the levels of myocardial?1 adrenoceptor protein at 2,7,30 days (P

OBJECTIVETo study possible mechanisms of Shangjuxu (ST37) and the large intestine.

METHODSTotally 40 SD rats were selected. The distension of end colon was used as injured afferent stimulus. Activities of locus coeruleus (LC) neurons were recorded by extracellular microelectrode technique. Shangjuxu (ST37) and Hegu (L14) were needled to observe general features of discharge reactions, distention of colon induced discharge reactions of LC, and its effects on distention of colon induced discharge reactions of LC.

RESULTSDistention of colon could induce incrased discharge of LC neurons by 127.33% ± 45.48%. But needling at Shangjuxu (ST37) and Hegu (L14) could inhibit this injured response by 38.24% ± 7.69% and 21.29% ± 13.16% respectively (all P < 0.01).

CONCLUSIONSNeedling at Shangjuxu (ST37) and afferent signals of colon distension converged and interacted with each other. Needling at Shangjuxu (ST37) could significantly inhibit colon distension induced discharge of LC neurons, which might be one of mechanisms for Shangjuxu (ST37) and the large intestine relationship.

ObjectiveTo investigate the role of active protein C (APC) in lipopolysaccharide (LPS) induced microglia activation.MethodsMicroglia from one day old Sprague-Dawley newborn rat was collected, purified and identified by primary culture and immunofluorescence staining, and then was randomly divided into four groups including LPS group (1.0μg/ml LPS plus 10μl phosphate buffered saline 12 h later), LPS+ APC group (1.0μg/ml LPS plus 0.1μg/ml APC 12 h later), APC group (10μl phosphate buffered saline plus 0.1μg/ml APC 12 h later) and control group (10μl phosphate buffered saline at each time point). The morphology of micaroglia in all groups was observed under microscope, and the expression of tumor necrosis factor-α (TNF-α) and protease-activated receptor-1 (PAR-1) were determined by immunofluorescence staining. One-way analysis of variance and LSD test were applied for statistical analysis.ResultsPrimary culture microglia was successful and the purity was no less than 99%. In LPS group, the microglia morphology was activated, and the expression of TNF-α was increased significantly than the control group (2.11±0.35 vs 1.38±0.28, LSD test,P=0.002). In LPS+APC group, the microglia morphological change was reversed, and the expression of TNF-α had no significant difference with the control group (1.35±0.36 vs 1.38±0.28, LSD test,P>0.05). The expression of PAR-1 in LPS+APC group was higher comparing with that in the control group (4.60±0.84 vs 2.64±0.41, LSD test,P=0.008) and the LPS group (2.44±0.86, LSD test,P=0.002). The expression of PAR-1 in APC group and LPS group had no obvious difference with control group (2.62±0.69, 2.44±0.86 vs 2.64±0.41, LSD test, bothP>0.05).ConclusionsBy increasing the level of PAR-1 in microglia, active protein C could inhibit the activation of miciroglia and the expression of TNF-α induced by lipopolysaccharide, therefore, protecting the brain tissues from inflammation-induced damage.

Objective To analyze the genetic characteristics of breakthrough varicella-zoster virus infection during the varicella outbreaks in Minhang District of Shanghai in 2013-2014. Methods Samples of the varicella-zoster liquid were collected from patients with chickenpox in Minhang District in 2013-2014 and used for the extraction of genomic DNA. The open reading frame ( ORF) of 22 and 62 regions were se-quenced and further analyzed by using bioinformatics methods. Results A total of 24 samples were success-fully collected and sequenced, and all of them were wild strains. Among the 24 varicella-zoster virus strains, 23 strains were highly homologous to the parental strain ( P-Oka) and the vaccine strain ( V-Oka) , indica-ting that they belonged to J genotype. Only one strain, whose genotype was between M and E, was highly ho-mologous to the mosaic( M) CA123 strain ( M1 genotype) , indicating that it might belong to M1 genotype. Conclusion The epidemic strains of varicella-zoster virus in Minhang District were mainly J genotype. Lo-cal epidemic of M and other genotypes of varicella-zoster virus also existed. There were some gene variations in different strains of J genotype. These varicella-zoster virus strains of non-vaccine genotypes might be one of the reasons causing the breakthrough cases of chicken pox.
