Objective This study aimed to explore the relationship between the traumatic experience in childhood and onset of obsession in adulthood,and the character of family environment of obsession patients.Methods Using Y-BOCS and CAT and FES-CV to evaluate 41 cases with OCD and 36 normal subjects respectively.Baaed on these scales,an edited interview schema for a semi-structured interview was choosed with both groups for 50 minutes respectively.Results ①Tbe whole score and scores of two subscales on punishment,negative-environment in CAT were all obviously higher in patients with obsession [(50.16± 21.03),(12.03±4.24),(19.77±9.74),for punishment:P<0.05,for others:P<0.01],and there were a significant difference in the two groups[(35.35±14.78),(9.92±2.51),(12.54±8.14)].The negative environment was chosen in regress equation,and could explain 14.67% of outcome of obsession. ②The scores of 4 ubacaies like cohesion,expressiveness,intellectual-cultural orientation,active-recreational orientation [(5.13±2.28),(4.10±2.12),(2.71±1.87),(2.52±2.34)] ,were all obviously lower than the normal control in FES-CV.While the subscore of conflict (5.03±2.21) was higher than the normal control(3.50±2.40),and all these differences were significant.When two factors of active-recreational orientation and cohesion in FES-CV were put into regression equation( R2 =0.2078 ,R2 =0.2784),they contribute 27.84% and the disease,and the active-recreational orientation factor can explain 20.78%.③The result of interview found significant difference between obsession groupand control group in parental personality,own personality,childhood experience,and family environment.Condusion The traumatic experience in childhood and unhealthy family environment do have association with onset and development of obsession,also they have a close relationship with the development of personality after adulthood.

Objective To investigate the effects of metformin on cell proliferation in differentiation degree of endometrial carcinoma cells and related mechanisms. Methods The endometrial cancer cell lines Ishikawa and AN3CA were used. Cell proliferation was assessed after exposure to metformin with or without epithelial growth factor receptor (EGFR) inhibitor AG1478 by cell counting kit-8 (CCK-8) method. EGFR mRNA was determined by reverse transcription (RT)-PCR. The expression of phosphorylation EGFR (p-EGFR) and total EGFR (t-EGFR) and phosphorylation extracellular signal-regulated kinase 1/2 (p-ERK1/2) and total ERK1/2 (t-ERK1/2) were examined by western blot. Results (1)CCK-8 experiment showed that metformin could inhibit the proliferation of endometrial cancer cells in a time-dependent manner and a dose-dependent manner (P<0.05), but the inhibition of well differentiated cell line Ishikawa was lower than that in poorly differentiated cells AN3CA (P<0.05). AG1478 also could inhibit the proliferation of endometrial cancer cells in a time-dependent manner and in a dose-dependent manner (P<0.05), but the inhibition rate of well differentiated cell line Ishikawa was higher than that in poorly differentiated cells AN3CA (P<0.05). Metformin+AG1478 also could inhibit the proliferation of endometrial cancer cells in a time-dependent manner and in a dose-dependent manner (P<0.05), and the inhibition of combined with metformin and AG1478 was stronger than that with a single application of drugs, but the inhibition rate of Ishikawa was higher than that in AN3CA (P<0.05).(2)RT-PCR method showed that different concentrations of metformin (0.01, 0.1, 1, 5, 10 mmol/L, respectively) for 24 hours, the expression level of EGFR mRNA in Ishikawa cells were respectively 0.74±0.03, 0.61±0.04, 0.46±0.03, 0.31±0.03 and 0.23±0.03, the expression level of EGFR mRNA in AN3CA cells were respectively 0.79±0.20, 0.61±0.03, 0.50±0.05, 0.32±0.03 and 0.26 ± 0.04, the inhibition effect showed a significant concentration-dependent manner (all P<0.01). (3) Western blot method displayed that the effect of metformin treated respectively 2, 4, 6 or 8 hours, there were not significant difference in the expression levels of t-EGFR protein and t-ERK1/2 between Ishikawa and AN3CA cells (all P>0.05). But the expression levels of p-EGFR and p-ERK1/2 protein were significantly lower between two groups (P<0.01), which showed a time-dependent manner(P<0.01). Conclusion Metformin could inhibit the proliferation of endometrial cancer cells, the inhibition is associated with the differentiation degree of cancer cells. Metformin could enhance the EGFR signaling pathway inhibitor AG1478 inhibition of endometrial cancer cells, which may inhibit EGFR expression of phosphorylated proteins to inhibit the phosphorylation of ERK1/2 proteins and then inhibit proliferation of endometrial cancer cells.

Objective To evaluate the risk factors for healthcare-associated infection(HAI)in senile dementia pa-tients,so as to adopt effective nursing measures to reduce the incidence of HAI.Methods Clinical data of 82 senile dementia patients aged≥60 years and hospitalized between January 2011 and June 2013 were analyzed retrospective-ly.Results Of 82 patients,28 (34.15%)developed HAI.The main infection site was lower respiratory tract(n=15,53.57%),followed by urinary tract(n=6,21 .43%).Univariate analysis revealed that risk factors for HAI in senile dementia patients were bedridden,long length of hospital stay ,dysphagia,indwelling urinary catheter,irra-tional use of antimicrobial agents,combined with tumor,and hypoproteinemia (all P <0.05 ).The main isolated bacteria were gram-negative bacilli(n=40,62.50%),the top three pathogens were Klebsiella pneumoniae (n=12, 18.75%),Escherichia coli (n =10,15.63%),and Pseudomonas aeruginosa (n =8,12.50%).Conclusion Reali-zing the risk factors and common pathogens of HAI in senile dementia patients is helpful for taking effective meas-ures to prevent and control the incidence of HAI .

Objective To study the expression of smad2/3 protein and the effects of flunarizine on the its expression in braln tissue following transient cerebral ischemie reperfusion in gerbils. Methods A cerebral ischemia-reperfusion model in gerbils was established by clamping both common carotids. Thirty-five gerbils were randomly divided into three groups, sham operation group, cerebral ischemia-reperfusion group and flunarizine treatment group. The expression of smad2/3 protein in brain tissue was detected by immunohistochemistry technique. Results Experimental results revealed that smad2/3 protein was expressed in neuroeyte in 35 gerbil brain. Compared with sham operation group, the expression of smad2/3 protein in neurecytes of cerebral isehemia-reperfusion group was evidently increased at the lst day, 3rd day and 7th day (P <0. 01). Compared with cerebral ischemia-reperfusion group, the expression of smad2/3 protein in neurecytes of gerbils in flunarizine treatment group was evidently decreased at these time point (P < 0.05). Condusions Smad2/3 protein was expressed in nettrcvytes of gerbils. Expression of smad2/3 protein in neuroeytes of gerbils was evidently increased following cerebral ischemic reperfusion, and its expression in flunarizine treatment group was evidently decreased.

In order to study whether patients with schizophrenia have cerebral injury, neuron-specific enolase (NSE) and myelin basic protein (MBP)in cerebrospinal fluid (CSF) of 33 patients with first episode schizophrenia and 9 from the control group were determined by double antibody sandwich enzyme immunoassay method. The results showed that there was significant difference in the NSE contents between the experimental group and control group (P<0.01). The NSE contents in CSF in the experimental group were positively correlated with MBP in schizophrenia patients (P< 0. 05). These findings suggested that patients with schizophrenia had cerebral injury.

Objectives To assess the performance of first trimester ultrasound screening for fetal structural and chromosomal anomalies based on a detailed anomaly and nuchal translucency (NT) scan at 11-13+6 weeks' gestation.Methods A prospective cohort study was conducted at Nanjing Drum Tower Hospital.Fetuses with a crown-rump length (CRL) between 45 mm and 84 mm scanned during December 2015 to March 2016 were enrolled in this study.After a detailed first-trimester anomaly scan followed the protocol of systematic standardized scan plans,fetuses with congenital abnormalities were screened out.Second trimester ultrasound screening and postnatal examination were performed for further examination of fetal anomalies.Cytogenetic analysis was performed on the fetuses with informed consent.Results (1) A total of 1 154 fetuses were enrolled in this study and among them,36 (3.1％) cases of fetal abnormalities were diagnosed through prenatal examination (35 cases) and postnatal examination (one case).(2) Twenty-one (58.3％) out of the 36 cases with structural and chromosomal anomalies were screened out by using the first-trimester scan,including eight cases of congenital cardiac defect (two cases of atrioventricular septal defect,one case of tricuspid atresia,one case of tetralogy of tetralogy,one case of right ventricle aneurysms and one cases of hypoplastic left heart syndrome combined with cystic hygroma with one case combined with polydactyly),four cases of central nervous system anomaly (three cases of exencephaly and one case of anencephaly combined with double outlet right ventricle),two cases of cleft palate/lip with one case combined with double outlet right ventricle,two cases of exomphalos,one case of amniotic band syndrome,one case of spinal bifida combined with megacystis,one case of umbilical cyst,one case of polydactyly and one case of cystic hygroma.One case of twin pregnancy chose selective fetocide to the fetus with exencephaly and 16 cases terminated pregnancy.The other four cases were confirmed by second trimester ultrasound screening and postnatal examination.Fourteen (38.9％,14/36) new cases of structural and chromosomal anomalies were detected by the second-trimester scan,six of which terminated the pregnancies and the rest were confirmed at term.One (2.8％,1/36) case of polydactyly was detected postnatally.(3) Chromosomal microarray analysis was performed on 28 cases,seven of which were identified as having chromosomal abnormalities including five cases detected in the first trimester and two cases detected in the second trimester.(4) Out of the 20 fetuses with abnormal NT in early trimester,which accounted for 1.7％ of all enrolled fetuses,nine were indentified with major structural or chromosomal abnormalies,a quarter of all abnormal fetus.Conclusions Detailed anomaly scan and NT scan in the first-trimester can increase the detection rate of fetal structural and chromosomal anomalies as compared with the traditional NT scan and provide earlier detection of severe fetal abnormalities as compared with second trimester anomaly scan.

Objective: To observe the effect of moxibustion therapy on heme oxygenase-1 (HO-1) and monocyte chemoattractant protein-3 (MCP-3) protein expressions in the colonic mucosa of rats with Crohn's disease (CD), and to explore the intestinal mucosal immune mechanism of moxibustion therapy in treating CD. Methods:The CD rat model was established using the internationally accepted Morris method. The rats were randomly divided into a model group, a herbal cake-partitioned moxibustion group, a mild moxibustion group, a cigarette moxibustion group and a hot compress group, which were compared with the normal group. Except the normal group and the model group, rats in the other groups accepted different moxibustion therapies on bilateral Tianshu (ST 25). Hematoxylin-eosin (HE) staining was conducted and the pathological changes of the colon were observed under light microscope; the expressions of HO-1 and MCP-3 protein in rat’s colonic mucosa were determined by immunohisto-chemistry. Results:Compared with the normal group, rats in the model group showed mucosal defect, villus destruction or loss, submucosal congestion and edema, glandular destruction or disappearance, reduced goblet cells, ulcer formation, significantly increased positive target area and positive target integral optical density of HO-1 and MCP-3 protein expression (allP<0.01). After treatment, compared with the model group, colonic mucosa was significantly improved in the herbal cake-partitioned moxibustion group and the mild moxibustion group, which mainly showed that the intestinal glands were arranged regularly, ulcer surfaces were covered by the neoformative epitheliums, or intestinal ulcers were replaced by the nascent granulation tissue, and submucosal edema was alleviated, with a small amount of inflammatory cell infiltration. The total areas and the integral optical densities of the positive targets for rat’s colonic mucosa HO-1 and MCP-3 protein expressions were decreased (allP<0.01). Compared with the cigarette moxibustion group and the hot compress group, the total areas and the integral optical densities of the positive targets for rat’s colonic mucosa HO-1 and MCP-3 protein expressions were significantly decreased (allP<0.01) in the herbal cake-partitioned moxibustion group and the mild moxibustion group. Conclusion:Herbal cake-partitioned moxibustion and mild moxibustion can significantly improve the inflammatory response of colonic mucosa in CD rats. It can down-regulate the expressions of HO-1 and MCP-3 proteins in the colonic mucosa of CD rats, which may be one of the mechanism in intestinal mucosal immunity caused by moxibustion therapy.
