ObjectiveTo observe effect of OT training on patients wearing the upper limd prosthesis. MethodsThe effect of OT to 30 patients with upper arm prosthesis was analyzed using FIM score before and after training. ResultsAfter 1-3-month OT training, the patients' FIM score were improved significantly(P<0.01).Conclusions OT is an effective method on the patients wearing upper arm prosthesis.

Objective To analyse the effects of serum estradiol levels during controlled ovarian hyperstimulation (COH) on the outcomes of in vitro fertilization and embryo transfer (IVF-ET). Methods The clinical data of 472 patients undergoing IVF-ET with GnRH analogues recombinant FSH long protocol were retrospectively analysed. The area under the curve (AUC) of estradiol (E2) level was calculated during COH, and patients were categorized into groups according to the percentile of AUC of E2(AUCE2) during COH. The general characteristics and parameters related to the outcomes of IVF-ET were compared among groups. Results The 10th percentile and 90th percentile of AUCE2 were 3 347.0 pmoL/L and 14 414.3 pmol/L, respectively. Four hundred and seventy-two patients were divided into lower reaction group (AUCE2 3 347.0 pmol/L, n=48), normal reaction group (14 414.3 pmol/L>AUCE2 > 3 347.0 pmol/L, n=376) and higher reaction group (AUCE2≥14 413.3 pmol/L, n=48). There was no significant difference in age, body mass index, baseline follicle stimulating hormone level, time of treatment with gonadotropin, endometrium thickness on day of transfer and embryos transferred(P>0.05). Compared with lower reaction group and normal reaction group, the number of oocytes per retrieval and number of embryos frozen were significantly larger(P<0.01) and the mild/severe ovarian hyperstimulation syndrome rate was significantly higher in higher reaction group(P<0.05). There was no significant difference in fertilization rate, cumulative embryo score, high-grade embryo rate, clinical pregnancy rate and implantation rate among groups (P> 0.05). Conclusion Sustained snpraphysiological serum E2 levels during the COH process do not adversely affect the quality of oocytes and embryos, clinical pregnancy rate and implantation rate to some extent in IVF-ET.

To study the mechanisms of total flavonoid from Glycyrrhizae Radix et Rhizoma (TFGR) and its ingredient isoliquiritigenin (ISL) on their regulation of M2 phenotype polarization of macrophages. IL-4 (60 μg x L(-1)) induced RAW264.7 cells for 6 h to establish the M2 macrophage model. TFGR and ISL restrained breast cancer cells migration with the aid of M2 macrophages in vitro. TFGR and ISL inhibited gene and protein expression of Arg-1, up-regulated gene of HO-1 and protein expression of iNOS, enhanced the expression of microRNA 155 and its target gene SHIP1, meanwhile down-regulated.the phosphorylation of STAT3 and STAT6. So TFGR and ISL were the bioactive fraction and ingredient in Glycyrrhizae Radix et Rhizoma to reverse M2 phenotype macrophages polarization. TFGR and ISL inhibited the promotion of M2 macrophages to breast cancer cells migration in vitro, STAT signal pathways and miR155 were partly involved.

Objective To explore the risk factors of Schistosoma japonicum infection in the residents in Xingzi County,Ji?angxi Province. Methods Six administrative villages from different areas were randomly selected by the cluster sampling meth?od as the study sites in Xingzi Country in 2013,and all the residents aged 5 years or above were investigated epidemiologically, and the schistosome infection was surveyed by Kato?Katz technique. The risk factors of schistosomiasis were analyzed by using the Chi?square test analysis and multivariate Logistic regression model. Results In 2013,there were 2 050 residents received the stool examination and 146 persons were positive,the schistosome infection rate was 7.1%. The Chi?square test showed that gender,age,occupation and education level were associated with the population infection rate(χ2=26.485、16.836、25.700、90.805,all P<0.05). The multivariate Logistic regression mode showed that the probability of schistosomiasis for the male was 3.041 times as much as that for the female;the probability of schistosomiasis for the illiteracy and primary education level crowd was 8.870 times as much as that for the college degree or above crowed;the probability of schistosomiasis for the junior middle school education level crowd was 5.598 times as much as that for the college degree or above crowed;the probability of schistoso?miasis for the high school education level crowd was 2.995 times as much as that for the college degree or above crowed;the probability of infection of fishermen was the highest,which was 3.053 times as much as that for the other professional crowds. Conclusions The risk factors of schistosome infection mainly include gender,occupation and the education level. We should strengthen the health education of schistosomiasis control,protection against the infested water contact,and so on.
