Objective To investigate the surgical strategy of recurrent rectuvaginal fistula. Methods Retrospectivly analyzed the clinical data of 13 patients with recurrent rectovaginal fistula from December 2001 to December 2008. The etiopathogenisis and the ways of treatment were analyzed. Results All the 13 patients with a transverse colostomy surgical repaired with Mason operation in the secondary intention,and recepted closure of colostomy in the third intention for treatment, all patients were cured. No recurrent fistula was identified with postoperative follow-up 4 - 84 months. Conclusions After recurrent rectovaginal fistula with multiple surgical treatment,the blood supply of local tissue is poor,the scar is serious. Selecting the appropriate timing of operation, adequate preoperative preparation, the application of transverse colostomy and Mason operation in different period could significantly enhance the successful operation rate.

Attention-deficit/hyperactivity disorder (ADHD)is one of the most common comorbidities of ASD.This article reviews the assessment tools and clinical research (prevalence,clinical characteristics and treat-ment)and fundamental research (iconography,genetics,neurophychology,electronerophysiology)of ASD with ADHD according to lately related articles.The findings suggested that there was lack of researches on treatment and iconography of ASD with ADHD and the conclusions were inconformity.Furthermore,most of the objects in these researches were children of normal intelligence.Thus future research should expand its objects to patients of adult and children with mental retardation and do further explore in iconography and treatment.

Objective:To compare the similarities and differences of doctor -patient trust building mechanism between doctors in urban and rural areas from the perspective of rural residents by the empirical study .Methods:Based on the field research and secondary in -depth interviews to the related personnel in H County of Beijing .Re-sults:There had obvious difference of doctor -patient trust building mechanism between doctors in urban and rural areas from the perspective of rural residents .Trust building mechanism between village doctors were mainly the trust of the similar social background , between the doctors in township health centers and city hospital were the trust based on reputation , institution-based trust , and relationship-based trust .Conclusion:The difference of re-gional and cultural between urban and rural areas ,the nature of medical institutions the relationship with doctors , reputation of medical institution and medical and health care system in urban and rural areas ,maybe the reasons that The difference of doctor -patient trust building mechanism between doctors in urban and rural areas .

OBJECTIVETo investigate the expression of long non-coding RNA-HOTAIR in prostate cancer cells and its effects on the growth and metastasis of the cells.

METHODSUsing quantitative reverse-transcription PCR (qRT-PCR), we determined the relative expression of HOTAIR in the normal human prostate epithelial cell line RWPE-I and prostate cancer cell lines PC-3 and DU145. We detected the effects of HOTAIR on the cell cycle and invasiveness of prostate cancer cells by RNA interference, flow cytometry, and Transwell mitration assay.

RESULTSThe expressions of HOTAIR in the PC3 and DU145 cells were increased 3.2 and 5.7 times, respectively, as compared with that in the normal RWPE-1 cells. After si-HOTAIR interference, the prostate cancer cells were arrested in the G2 phase and downregulated in the G1 phase. The invasive ability of the prostate cancer cells was evidently inhibited, with the inhibition rates of 32% and 44% of the PC3 cells and 43% and 34% of the DU145 cells for si-HOTAIR1 and si-HOTAIR2, respectively.

CONCLUSIONIncRNA HOTAIR is highly expressed in prostate cancer, which is associated with the growth and invasiveness of prostate cancer cells. HOTAIR is potentially a novel marker for the diagnosis and prognosis of prostate cancer.

To evaluate the properties of solidifying volatile oil with graphene oxide, clove oil and zedoary turmeric oil were solidified by graphene oxide. The amount of graphene oxide was optimized with the eugenol yield and curcumol yield as criteria. Curing powder was characterized by differential scanning calorimetry (DSC) and scanning electron microscopy (SEM). The effects of graphene oxide on dissolution in vitro and thermal stability of active components were studied. The optimum solidification ratio of graphene oxide to volatile oil was 1:1. Dissolution rate of active components had rare influence while their thermal stability improved after volatile oil was solidified. Solidifying herbal volatile oil with graphene oxide deserves further study.

The expressions of StAR (steroidogenic acute regulatory protein) mRNA in testes from 7,14,23 and 37 day-old piglets were studied by tissue in situ hybridization. The results indicated that in the testes of piglets, StARmRNA was expressed in Leydig cells of pig testes. The expression level of StARmRNA was lower in 7 days piglets but higher in 14,23,37 days. The results indicated that StAR gene played an important role in steroid biosynthesis.

Background Previous experimental and clinical studies have proved that elevated serum uric acid increased risk for developing hypertension.Whereas,there are a paucity of information on the relationship between serum uric acid and prehypertension.Objective The purpose of this research is to evaluate the association between the serum uric acid and prehypertension.Method A cohort of seven thousand eight hundred thirty-nine subjects without hypertension and other cardiovascular diseases were recruited from a cross sectional study in urban and rural place in 9 provinces during 2005-2006.Based on serum uric acid(324 ?mol/L for overall population,366 ?mol/L for male,285 ?mol/L for female),people were categorized into quartiles.The odds ratio for prehypertension was calculat ed with the lowest quartile as the reference.Results The prevalence of prehypertension increased with increasing uric acid in total population(P324 ?mol/L)to lowest quartile 1(

Objective To investigate the effect of brain-derived neurotrophic factor (BDNF) gene modified neural stem cells (NSCs)transplantation on cerebral ischemic injury in rats.Methods NSCs from newborn rat hippocampus were isolated,cultured in a medium containing fibroblast factor (FGF) in vitro. Their proliferation and differentiation were detected by immunohistochemistry.Virus vectors pLXSN-BDNF were built and BDNF were transfected into NSCs.Biological activity were detected to obtained engineering stem cells of BDNF protein with secretary activity.Middle cerebral artery occlusion (MCAO) models were made and transplanted with NSCs-BDNF by stereotaxic technique.The effect of transplantation on MCAO models was evaluated histologically and behaviorally.Results Statistical analysis showed that the behavioral performance of the animals improved after transplantation (Longa mark being 1.343?0.293 four weeks after stem cell transplantation).The number of hippocampal dentate gyrus neurons increased to 87.5%?6.6% , four weeks after stem cell transplantation on Nissle stained hippocampal sections,which was significantly different from that of controls.Positively BrdU stained neural stem cells revealed by immunohistochemistry in the cultured cells and in the transplanted brain sections,indicated that the engineering cells transplanted had survived in the host brain and began to proliferate.Conclusion Transplantation of BDNF genetically modified NSCs can effectively promote the recovery from cerebral ischemic injury.
