quamous metaplasia occurred, the expression of occludin and ZO-1 in cells were similar to those in control group, which might play a role in the defense function of neovaginal mucosa.

Objective To study the method of preparation of donor liver in liver transplantation. Methods The methods and skills of donor liver preparation and the anomaly artery reconstruction of graft in 64 cases of orthotopic liver transplantation (OLT) were retrospectively analyzed. Results All allografts had preparation and were suitable for clinical transplantation. Thirteen cases with hepatic artery anatomy variation were found. Among the 13 cases, 5 cases were reconstructed. Splenic artery (3/5) and gastro-duodenal artery (2/5) were typically used for anastomosis of the variant hepatic arteries. No complications resulted from donor liver preparation. Conclusions Correct preparation of the donor hepatic artery and biliary tracts, can decrease the incidence of hepatic artery and biliary tract complications after liver transplantation, and is the key to ensure successful donor liver preparation.

Objective To investigate re-innervation in the neovaginal mucosa of patients underwent sigmoid colon vaginoplasty in treatment of Mayer-Rokitansky-Kistner-Hauser Syndrome (MRKHS).Methods Biopsies in the upper third of the posterior neovagina were taken in 20 patients treated by sigmoid colon vaginoplasty at 1, 2 and 3 years after surgery, respectively. Protein gene product 9. 5 ( PGP 9. 5 ),vasoactive intestinal peptide (VIP) and neuropeptide Y (NPY) were detected by immunohistochemical method and compared with those in intact sigmoid colon mucosa. Results ( 1 ) Density of nerve fiber:abundant distribution of PGP 9. 5 nerve fibers were observed in the mucosal muscle layer, submucosa, and smooth muscle layer of the neovagina. The nerve fibers of VIP and NPY immunoreactivity were mainly distributed around blood vessels and in the smooth muscles. In the neovagina, the density of nerve fibers of PGP 9. 5 of 17 ± 6 were much more than VIP of 2. 9 ± 1.0 and NPY of 2. 5 ± 0. 8 significantly ( P ＜ 0. 05 ).( 2 ) Expression of PGP 9. 5 in neovagina: at 1 year after surgery, PGP 9. 5 positive expression of 14 ± 4 was significantly lower in the neovagina than 28 ± 7 in the intact sigmoid colon( P ＜ 0. 05 ). However, after 2 to 3 years, its expression displayed an upgrade tendency in the neovagina and was significantly higher at the 3 year postoperatively than that at the 1 years postoperatively ( 22 ± 7 vs. 14 ± 4, P ＜ 0. 05 ). The changes were much more obvious in submucosa. (3) The expression of VIP and NPY in neovagina: at 1 year after surgery, VIP and NPY positive nerve fibers were also decreased in the neovagina when compared with those in the intact sigmoid colon ( 2. 3 ± 0. 7 vs. 5.3 ± 1.4, P ＜ 0. 05; 2.5 ± 1. 1 vs. 5.5 ± 1.1, P ＜ 0. 05 ) . At 2 to 3 years after surgery, the positive VIP fiber showed initially decreased and subsequently increased tendency. The density of VIP of 3.7 ± 0. 7 in the neovagina at 3 years postoperatively was higher than 2. 3 ±0. 7 at 1 years postoperatively (P ＜ 0. 05 ). No significant up-regulation was observed in NPY-positive expression in the neovagina within 3 years after operation. Conclusions Distribution of sensory PGP 9. 5,VIP and NPY immunoreactive nerve fibers was similar to the pattern observed within the intact sigmoid colon wall. The number of nerve fibers in the neovagina decreased after surgery and then increased subsequently within 3 years after surgery.

Objective:To explore the diagnostic value of the serial position effect combined with delayed recall of auditory verbal learning test in diagnosing the elderly patients with different levels of cognitive impairment.Methods:A total of 310 subjects were enrolled and divided into three groups: the normal control group(NC group, n=128), the mild cognitive impairment group(MCI group, n=133)and the mild Alzheimer's disease group(mild AD group, n=149)matched for gender, age and education level.Comprehensive neuro-psychological tests were performed on all subjects, and the Auditory Verbal Learning Test-Huashan version(AVLT-H)was used to analyze the serial position effect.Results:There were significant differences in the primacy effect of the second and third time of immediate recall, short-term and long-term delayed recall among the three groups( P<0.05), but no difference was found in the recency effect between the MCI and mild AD groups( P>0.05). The long-term delayed primacy effect combined with the short-term delayed recall showed a better validity to distinguish those elderly subjects with different levels of cognitive impairment than other memorial indexes, and the correlative sensitivity and specificity were 83.21% and 71.43%(NC group vs.MCI group), 85.71% and 92.86%(NC group vs.mild AD group), 66.67% and 75.57%(MCI group vs.mild AD group), respectively. Conclusions:The long-term delayed primacy effect combined with the short-term delayed recall can assist in distinguishing elderly patients with different levels of cognitive impairment.

AIM: To explore the putative effects of sterigmatocystin (ST) on human help T lymphocyte(Th1)function. METHODS: The effects of ST on interferon-?(IFN-?)secretion of human peripheral blood mononuclear cells(HPBMc) in vitro were determined with ELISA method. RESULTS: The effects of ST on IFN-? secretion of HPBMc in vitro were closely dependent on ST concentrations. ST at relatively lower concentrations (0.03125-0.12500 mg/L) showed inhibiting effects on IFN-? secretion. While, stimulating effects could be found when ST concentration was above 0.25mg/L. The highest level was seen in ST 1 mg/L group ( P

AIM: To explore the effect of deoxynivalenol on apoptosis and proliferation of mouse thymocytes in vivo. METHODS: Effect of deoxynivalenol at different concentrations on apoptosis and proliferation of mouse thymocytes in vivo were studied with animal experiment, electron microscopic observation, DNA agarose gel electrophoresis and flow cytometric analyses. RESULTS: FCM analysis showed that the apoptosis rates of the thymocytes in DON groups (0 5 mg/kg, 1 mg/kg, 2 mg/kg, 4 mg/kg and 8 mg/kg) were significantly higher than that in control ( P

Objective To estimate the prevalence and associated factors of adult female urinary incontinence in Hebei province. Methods Stratified and multistage sampling method was used, between January 2016 to May 2016, to investigate the target population in Hebei province. While, logistic regression was used to analyse datas. Results A population-based survey was conducted in 2 450 women in Hebei province, there were 2 408 effective questionnaires after deleting 48 invalid questionnaires. According to the results, the average age of subjects was (56±15) years old, and the urinary incontinence prevalence of adult female in Hebei province was 27.70%(667/2 408). Stress urinary incontinence, urge urinary incontinence and mixed urinary incontinence were diagnosed as 23.13%(557/2 408), 1.58%(38/2 408) and 2.99%(72/2 408), respectively. There were only 2.85% (19/667) urinary incontinence patients seeking medical help. The results of logistic regression analysis showed that age, daily water intake, pulmonary diseases, urinary tract infection, hypertension, chronic low back pain, dysmenorrhea, vaginitis, abortion, mode of delivery, postpartum infection were statistically significant (all P≤0.05). Among these factors, cesarean section was the protective factor for urinary incontinence (OR=0.365, 95%CI: 0.195-0.685, P<0.01). Conclusions The prevalence of urinary incontinence in adult female in Hebei province is high, and there are few patients seeking medical help. It is a common disorder in women and is associated with many factors;among these factors, cesarean section is the protective factor for urinary incontinence.
