Objective To investigate the composing characteristics and drug resistances of pathogens isolated from genital tracts in premature rupture of membranes of obstetrics from 2012 to 2014 ,for instructing clinical application of antibiotics reasonably . Methods A retrospective investigation analysis was made for all the isolated bacteria from genital tracts specimens as well as their drug resistances from 2012 to 2014 .Results The results shows that 598 strains of bacterial pathogens were isolated from 2000 detected samples ,The infection rate of bacterial pathogens was 29 .90% .The top four bacteria pathogens were E .coli(31 .44% ) ,Can . albicans(20 .90% ) ,Str .agalactiae(19 .23% ) and Sta .aureus(10 .03% ) .E .coli and Sta .aureus were highly resistant to commonly used antibiotics and demonstrated multi‐drug resistance .Str .agalactiae and Can .albicans were lowly resistant to commonly used antibiotics .Conclusion Inspecting pathogens and studying the composition of pathogens and the trend of their drug resistance are im ‐ portant to rationally select antibiotics ,decrease the occurrence of drug resistant strains in perinatal period ,and control the outbreak and prevalence of nosocomial infection .

Objective To observe the effect of integrative Chinese and western medicine fast-track rehabilitation in surgery (FTS) for patients during peri-operation period of gynecological laparoscopy. Methods A total of 226 patients receiving gynecological laparoscopic surgery were randomized into observation group and control group, 113 cases in each group. The observation group received integrative Chinese and western FTS treatment, and the control group received routine non-surgery treatment. After operation, time for the first post-operation anal gas evacuation, time for out-of-bed activity, hospitalization time, and incidence of post-operation complications were compared between the two groups. Results In the observation group, time for the first post-operation anal gas evacuation and time for out-of-bed activity were earlier, and hospitalization time was shorter than those in the control group (P<0.05). The incidence of post-operation complications was 0.9%, lower than 4.4% in the control group ( P<0.05). Conclusion Integrative Chinese and western medicine fast-track rehabilitation in surgery shows certain effect on promoting enterokinesia, shortening time for the anal gas evacuation, reducing post-operation complica-tions, promoting post-operation recovery of gastrointestinal function of patients receiving gynecological la-paroscopy .

Objective To explore the effect of multiple-formed nursing teaching ward-round.Methods Trainings and practices about muhiple-formed nursing teaching ward-round were executed to clinical instruction teachers.Results 95.9%of nursing students were satisfied with the quality of nursing teaching ward-round.After training ang practices,the evaluation to the nursing teaching ward-round and the scores of theoretic and operation examination of nursing students raised significantly(P＜0.05).Conclusions The trainings and practices improve the teachers' ability of utilizing multiple-formed nursing teaching ward-round,which not only enhance the students' study initiative,but also improve the query of nursing teaching teaching ward-round.

Purpose: Four and a half LIM protein 1 (FHL1) is involved in breast cancer (BC) development, but the regulatory mechanism involved remain unclear. In the present study, we examined the role of FHL1 in BC development. Methods: The expression of FHL1, miR-183-5p, and miR-96-5p in BC tissues was analyzed using StarBase analysis. FHL1 expression in BC tissues, a normal human breast epithelial cell line, and BC cell lines was detected using quantitative reverse transcription polymerase chain reaction (qRT-PCR). The relationship between FHL1 and miR-183-5p/miR-96-5p was analyzed via Pearson's rank correlation, TargetScan, and a dual-luciferase reporter assay. BT549 and MDA-MB-231 cells were transfected with either FHL1 and miR-183-5p mimics, or siFHL1 and a miR-183-5p inhibitor, respectively. The viability, colony number, migration, invasion, and tube length of BT549 and MDA-MB-231 cells were examined using cell counting kit-8, colony formation, wound-healing, Transwell, and tube formation assays, respectively. The levels of FHL1, vascular endothelial growth factor (VEGF), p53, E-cadherin, N-cadherin, and vimentin were quantified using western blotting and qRT-PCR. Results: FHL1 expression was downregulated in BC tissues and cells, whereas miR-183-5p and miR-96-5p were upregulated in BC tissues (negative correlation with FHL1 expression).FHL1 overexpression inhibited the viability, colony number, migration, and invasion of BC cells and the expression of VEGF, N-cadherin, and vimentin, and increased the expression of FHL1, p53, and E-cadherin in BT549 cells. Furthermore, a miR-183-5p mimic reversed these effects of FHL1 overexpression, whereas FHL1 silencing caused opposite results to those observed in MDA-MB-231 cells; however, this was reversed by a miR-183-5p inhibitor. Conclusion Our study suggests that miR-183-5p promotes cell proliferation, metastasis, and angiogenesis by negatively regulating FHL1 in BC.

To prepare a soluble human extracellular III domain of Flt1 and analyze its biological activity. The gene encoding extracellular domain III of Flt-1 was cloned into the expression vector pAZY by RT-PCR from human umbilical vein endothelial cell (HUVEC), and induced to express in Escherichia coli by low phosphoric medium, the product was purified by E-tag affinity chromatography. SDS-PAGE and Western blotting analysis showed that Flt-1 gene domain III gene was expressed in E. coli and the yield of the soluble fusion protein was about 1.10 mg/L. Enzyme-Linked ImmunoSorbent Assay (ELISA) revealed that the Flt-1 domain III was able to bind to VEGF165 dose-dependently. Monolayer denudation assay and Transwell assay showed that the fusion protein could inhibit HUVECs migration induced by conditional medium with 50 ng/mL VEGF165 and 100 ng/mL bFGF. In conclusion, Flt-1 gene domain III gene has been successfully cloned and expressed in E. coli, which will be useful in both the research on the function of Flt-1 gene domain III and preparation of anti-Flt-1 monoclonal antibody in the future.
