Objective To investigate the role of antisense RNA of plasminogen activator inhibitor 1 (PAI 1) in regulating the expression of PAI 1 and vascular endothelial growth factor (VEGF) in aorta endothelial cells (EC) cultured in vitro. Methods The second extron of PAI 1 was amplified by polymerase chain reaction(PCR) and the product was inserted into eukaryotic cell expression vector pcDNA3.1(-) to construct PAI 1 antisence RNA recombinant plasmid. The recombinant plasmid was transfected into EC and the PAI 1 expression was detected by immunohistochemistry, Westernblot and ELISA. The effects of PAI 1 variation on VEGF were examined by immunofluorescence method. Results PAI 1 antigen was the lowest (0 017 ng/ml) in cells and the immunofluorescence representing the expression of VEGF in the cytoplasm showed the weakest at the third day after transfection. At the fifth day, PAI 1 antigen increased to 0 093 ng/ml with VEGF expression increased correspondingly. At the seventh day, PAI 1 antigen(0 143 ng/ml) and VEGF increased closed to normal level. Conclusions PAI 1 antisense RNA blocked the translation of PAI 1 proteins effectively and inhibited the expression of VEGF in aorta endothelial cells.

Objective To explore the efficacy and safety of terminating biochemical pregnancy (the stage in which intrauterine or ectopic pregnancy cannot be confirmed) with mifepristone and misoprostol. Methods Mifepristone (150 mg) combined with misoprostol (600 ?g) 3 days later were given to 500 biochemical pregnancies (G_1),500 early clinical pregnancies (G_2) and 500 clinical pregnancies (G_3) which were classified according to amenorrhea days,serum human chorionic gonadotropin-beta subunit (?- hCG) and vaginal B-ultrasonic examinations.All were observed for 6 hours after taking misoprostol and returned for assessment per week.Results Expulsion of conceptus was G_1 123 (24.6%,123/500),G_2 438 (87.6%,438/500) and G_3 467 (93.4%,467/500).Failure rate was G_1 6 (1.2%,6/500),G_2 24 (4.8%,24/500) and G_3 79 (15.8%,79/500) for ongoing pregnancies,hospitalizations for suspected ectopic pregnancies and surgical intervention for heavy or long-time bleeding.Bleeding cases during the administration of mifepristone were G_1 272 (54.4%,272/500),G_2 141 (28.2%,141/500) and G_3 87 (17.4%,87/500);the mean bleeding days were G_1 (5.8?1.5),G_2 (9.0?2.9) and G_3 (14.3?5.9) days.Other side effects including abdominal pain,nausea,vomiting and diarrhea were low and light in each group,increasing with advancing gestational age.Menses recovery was 486 (97.2%,486/500),452 (90.4%,452/500) and 433 (86.6%,433/500) for each group on scheduled time.Satisfaction was 499 (99.8%,499/500),485 (97.0%,485/500) and 369 (73.8%,369/500) respectively.Conclusion Mifepristone and misoprostol in combination is as safe,and effective for termination of biochemical pregnancies as ordinary medical abortion.It does not need to wait till ectopie pregnancy is excluded.

ObjectiveTo compare the surgical outcomes of total abdominal hysterectomy (TAH) and total vaginal hysterectomy (TVH).MethodsThe clinical data of 509 TAH cases and 799 TVH cases including operating time, bleeding volume, days being in hospital and outcome of 3 months following-up were analyzed retrospectively.ResultsThe average operating time and bleeding volume of TVH were 47.6 minutes and 199 ml respectively, less than that of TAH (128 minutes and 241 ml). The days being in hospital of TVH were also less that of TAH, and 12-Short Form Health Survey (SF-12) scores of TVH were higher than that of TAH.ConclusionTVH has minor lesion and is helpful for improving the quality of patients' life.

The volatile oils of endophyte isolates R1 (Acremonium sp.) and R2 (Acremonium sp.) from Aqui-laria sinensis were extracted by solvent method. Twenty and sixteen ingredients were identified from the volatile oils of R1 and R2 by GC-MS, respectively. Fatty acids, such as oleic acid, linoleic acid, hexa-decanoic acid etc., were the main components, whereas terpenoids like 1,8-cineole, zingiberene, ar-curcumene were also found in both oils. It’s the first report about the volatile oil constituents of endophyte isolates from A. sinensis.

PcoI-PcoR is a quorum-sensing (QS) system influencing the biofilm formation and rhizosphere colonization in Pseudomonas fluorescens 2P24. The expression of the pcoI, a N-acyl-homoserne lactone (AHL) biosynthase gene, is under the regulation of a number of chromosomal factors, such as the GacS-GacA two-component system. In this paper, we investigated the upstream regulators that influence the transcription of pcoI gene using a chromosomal pcoI-lacZ fusion reporter strain PM203. Cosmids containing genomic DNA of the wild-type strain 2P24 were introduced into the reporter strain PM203 (gacA—, pcoI-lacZ) to screen positive transcriptional regulators of pcoI gene. One of them named pP32-24, which contained a 5-kb Pst I functional fragment was selected. Further analysis identified that the pcoI was the gene responsible for the increase of the pcoI-lacZ expression. The expression of pcoI-lacZ reporter was alsoimproved in both PM101 (pcoI-lacZ) and its gacAmutant PM203 after addition of exogenous AHL, indicating that the expression of pcoI is positively regulated by AHL (autoinduction) in strain 2P24. In addition, deletion mutagenesis and complementation experiments demonstrated that the transcriptional regulator PcoR positively controlled the expression of pcoI and the formation of biofilm. These results suggest that, in strain 2P24, the expression of PcoI-PcoR QS system is auto-inducted, and the transcriptional factor PcoR is involved in the regulation of pcoI transcription and the biofilm formation.

Objective To explore the post training needs,training content,training mode and the advantages and disadvantages of the existing training from the general practitioner perspective,in order to provide reasonable suggestions for the management institutions to improve the quality and effect of the post training for all general practitioners.Methods In October,2013 a questionnaire survey was conducted to 197 family physicians for their post training needs,training content and training mode.According to the interview outline,an in-depth individual interview was conducted to 20 leaders and general practitioners from the community health service center in Beijing Xicheng District on the advantages and disadvantages of general medical training.All survey information databases were established using FoxPro 6.0 software and double entry.Package was statistically analyzed with SPSS 19.0 statistical software,qualitative data using rate to represent; interviews with text descriptions,coding classification analysis.Results More than 70％ of general practitioners had the demand for strengthening the training of the clinical medicine,the knowledge of humanities and social sciences as well as clinical research methods,but the demand for the training of general medical theory and basic medicine was small,only accounting for 22.50％ general practitioners.More than 90.00％ of general practitioners were in favor of targeted flexible training methods.More than 85.00％ of general practitioners believed that existing training teachers' teaching abilities were very good,and they agreed to open general practitioner training project in medical colleges and universities.The surveyed physicians also made some criticism about too many training departments,low training quality,too many training programs,and training content repetition etc..Conclusion According to the general medical post training needs,human and scientific research of targeted training should be increased by using case discussion,site visit and many flexible and diverse teaching methods and various departments should also be coordinated and the training incentive and evaluation mechanism should be improved to guarantee the quality of training.
