Objective To explore the resilience traits of male juvenile delinquents with high traumatic experiences and the relationship on resilience and personality,family environment.Methods 147 male juvenile delinquents selected by self-made traumatic experience questionnaire were surveyed with the Resilience Scale for Chinese Adolescent,Eysenck Personality Questionnaire and Family Environment Scale.The data were statistically analyzed by Pearson correlation analysis and stepwise Regression Analysis.Results The total scores of resilience in male juvenile delinquents with high trauma experiences were (75.98 ± 14.03).Besides the scores of goal planning (3.47±4.23),the scores of affect control(1.94±2.85),positive thinking(2.31±3.47),family support(1.89±3.84)and help seeking (2.92±3.38)were all below 3.Differences of goal planning,positive thinking,family support had been found in male juvenile delinquents with high trauma experiences on the factors including educational level,rural or urban family,whether only-child family,whether single-parent family.The delinquents' resilience was correlated with their personality(r=-0.357-0.175) and family environment (r=-0.185-0.272) in several dimensions (P ＜0.05).Neuroticism,family conflict and psychoticism predicted resilience negatively (β=-2.354,-0.135,-0.194,P＜0.05).Family cohesion predicted resilience positively(β=1.389,P＜0.001).Conclusion The resilience of male juvenile delinquents with high traumatic experiences is poor and personality,and family environment has significant influences on their resiliences.

Objective To build relationship model of personality, life style and mental health for medical students. Methods 869 medical students were surveyed with Eysenk Personality Questionnaire, Symptom Check List 90(SCL-90), common condition questionnaire, to describe the situation of medical students mental health and personality, and a relationship model was set up by structural equation modeling. Results The situation of mental health for medical students was well. Male students showed significantly higher lie than female students. The only children showed significant higher lie than those having siblings. Neuroticism, life style, lie, sleep time everyday, boarding and lodging in middle school, friends, only child, degree of parents attention had significant direct influence on mental health (β =0.508, 0.136, 0.100, 0.082, 0.076, -0.057, 0.057, 0.051 ). Neuroticism, friends and sleep time everyday affected mental health in an indirect way through life style (β = 0.044, - 0. 008, 0.007). Only child affected mental health in an indirect way through boarding and lodging in middle school (β = -0.026). Lie affected mental health in an indirect way through neuroticism (β =0. 195). Conclusion The important effects of personality, life style on mental health are further supported in this study.

Objective To investigate the effect of the secondary transurethral resection in the treatment of non-muscle invasive bladder cancer(NMIBC).Methods 186 cases with NMIBC were randomly divided into control and experimental groups,both groups were treated by transurethral resection of bladder tumor(TURBT),and experimental group received the secondary TURBT after 4 weeks of the first TURBT.The recurrences of two groups were compared.Results The recurrence rate was significantly lower in experimental group than in the control group(13.8％ vs.37.0％,x2 =13.17,P＜0.05).The recurrence number of the original site was significantly less in experimental group than in the control group(x2 =8.35,P＜0.05).Conclusions The secondary TURBT plays a positive role in NMIBC recurrence.

Objective To investigate the clinical features of Escherichia coli pneumonia, the positive rate of extend-spectrumβ-lactamase (ESBLs) produced by Escherichia coli and antimicrobial resistance of Escherichia coli. Methods Three hundred and thirty-six infants with Escherichia coli pneumonia were divided into community acquired infection group and hos-pital acquired infection group from Jun 2003 to Jun 2013. The clinical data of those patients were collected and analyzed. The ESBLs were examined, and drug susceptibility results were analyzed. Results Infants under 6 months had higher infective rate of Escherichia coli. The Escherichia coli pneumonia had similar clinical manifestations as Gram negative bacterial pneumonia. ESBLs were found in most strains (58.3%, 196/336), positive rate of ESBLs of hospital acquired infection group (84.00%) was higher than that of community acquired infection group (50.96%) (χ2=26.17, P<0.05). There was no difference of ESBLs posi-tive rate between the community acquired infection groups during Jun 2003-May 2008 and those during Jun 2008-Jun 2013 (χ2=0.30, P>0.05). The ESBLs positive rate of hospital acquired infection group was significantly increased from 76.74%(Jun 2003-May 2008) to 93.75% (Jun 2008-Jun 2013) (χ2=3.95, P<0.05). The most sensitive antibiotic was carbapenem. Conclusions Escherichia coli pneumonia mainly occurs in infants, usually with severe clinical situations and more persistent. The hospital acquired infection is the high risk factor of acquiring ESBLs. Antibiotics should be prescribed depending on community acquired infection or hospital acquired infection.

Objective To study the inhibitory effect of recombinant adenoviruses carrying the mouse endostatin gene on the therapy of endometriosis in nude mice.Methods Animal endometriosis models were established by inoculating human endometrial fragments.Mice were randomly divided into three groups(10 each):PBS control group,Ad-lacZ group and Ad-mEndo therapy group when ectopic lesion diameter reached 5-10mm.The ectopic lesion size was measured every day.The expression of endostatin in ectopic lesion was detected by immunohistochemical stainining.The microvessel density(MVD) of ectopic lesion was traced by CD34 immunohistological labeling.Meanwhile,the contents of steroid hormone and histological changes in mice uterus and ovary were detected.Results The titer of the recombinant adenovirus was about 5.0?109pfu/ml.The endostatin gene was transferred into mice successfully and expressed effectively.The lesion volume was significantly less in Ad-mEndo group(34.3?11.2mm3) than that in Ad-lacZ group(93.3?10.7mm3) and PBS group(90.4?18.7mm3,P

Aim To study the protective effects of dipfluzine against the whole cerebral ischemia and reperfusion injury and its mechanisms.Methods Four-vessel occlusion method was used to make the cerebral ischemia-reperfusion model.In early period of reperfusion,several including LDH,MDA,SOD and brain water content were tested.And in the late period of reperfusion,the delayed neuronal death and amnesia induced by reperfusion were studied.Results The contents of brain water and MDA were increased,and the activities of SOD and LDH were decreased after ischemia and reperfusion injury.The hippocampal structure and memory of rats were also destroyed in the delayed neuronal death.Dip reversed the changes obviously.It had antagonistic effect on brain edema and lipid oxidation,it also protected the neurons of hippocampal CA1 regions from ischemia injury.Conclusion Dip had protective effects on the early stage of reperfusion injury,and delayed neuronal death after the whole cerebral ischemia and reperfusion,which were possibly due to the antagonistic effect on lipid peroxidation.

Objective To investigate the correlation between serum glutamate levels and post-stroke depression (PSD). Methods The consecutive patients with acute ischemic stroke were enroled. At 3 month after onset, the PSD diagnosis was conducted according to the American Diagnostic and Statistical Manual of Mental Disorders (4th Edition) somatic disease caused mood disorder and Hamilton depression scale (HAMD) was used to evaluate the severity of depressive symptoms in patients with PSD. The demographics and baseline clinical data were compared and analyzed in the PSD group and the non-PSD group. Results A total of 177 patients were enroled in the study, including 55 in the PSD group and 122 in the non-PSD group. The age (64. 4 ± 7. 8 years vs. 60. 1 ± 11. 1 years; t = - 2. 575, P = 0. 012), NIHSS scores (median and interquartile: 6 [5 - 8] vs. 3 [2 - 5 ]; Z = - 5. 463, P = 0. 002 ), serum homocysteine (16. 9 ± 4. 9 μmol/L vs. 14. 3 ± 3. 9 μmol/L; t = - 3. 929, P = 0. 001 ), high-sensitivity C-reactive protein (1. 0 [0. 8 - 1. 7] mg/L vs. 0. 4 [0. 7 - 1. 3] mg/L; Z = - 3. 439, P = 0. 002 ), glutamate levels (279 [205 - 345] μmol/L vs. 161 [110 - 209] μmol/L; Z = - 6. 172, P = 0. 001 ), as wel as the proportion of women (50. 9% vs. 34. 4% ; χ2 = 4. 308, P = 0. 038) in the PSD group were significantly higher than those in the non-PSD group, while the education level was significantly lower than that in the non-PSD group (χ2 = 9. 679, P = 0. 003). Spearman correlation analysis showed that serum glutamate levels were significant positive correlated with HAMD scores ( r = 0. 491, P < 0. 001 ). Multivariate logistic regression analysis showed that the increased serum glutamate level (odd ratio 1. 016, 95% confidence interval 1. 010 - 1. 023; P = 0. 002) was an independent risk factor for PSD in patients with acute ischemic stroke. Conclusions The increased serum glutamate level may be an independent risk factor for PSD.

Objective To investigate the relationship between proliferative diabetic retinopathy and E-selectin level .Meth-ods Ninty-two patients with diabetic retinopathy were divided into two groups based on the results of fundus fluorescence angiography :basic diabetic retinopathy (BDR) group, and proliferative diabetic retinopathy (PDR) group.Body mass index (BMI), fasting blood-glucose (FPG), total cholesterol (TC), triglycerides (TG), hemoglobin A1c (HbA1c), systolic blood pressure (SBP), diastolic blood pressure ( DBP) , and E-selectin levels of two groups were determined and compared .Results Compared with normal control group, the BDR and PDR group soluble E-selectin (sE-sel), FPG, HbA1c levels were increased significantly ( P <0.05).There was no significant difference in the SBP, DBP, BMI, TC, and TG levels in BDR group compared with control group ( P >0.05).The level of E-sel was positively correlated with HbA 1c and FBG in diabetic retinopathy patients .Conclusions High levels of sE-sel, HbA1c, and FPG were the important risk factors for diabetic retinopathy , and were closely related to the severity of PDR .Detection of serum sE-sel and HbA1c will help to predict the severity and prognosis of diabetic retinopathy .

Objective To study the influence factors and prevention measures of complication of laparoscopic uter?ine surgery. Methods Patient who underwent laparoscopic uterine surgery were collected (n=415) and divided into hyster?ectomy group (n=310) and myomectomy group (n=105). Intraoperative and postoperative complications such as gastrointesti?nal injury, urinary injury and bleeding were recorded and compared between these two groups. Base on their uterine size, pa?tients were divided into Group A (uterine volume ≤300 cm3), Group B (300 cm3 0.05). The inci?dence of intraoperative or postoperative bleeding was 1.93%(8/415) and incidence of gastrointestinal damage or urinary inju?ry rate was 0.96%(8/415). The incidence of complications in group C was 20.0%(8/40) which is higher than that in group A (2.8%;5/179) and group B (5.1%;10/196). P<0.01 in all cases. The difference between group A and group B was not signif?icant (P>0.05). The incidence in pelvic adhesions group is higher than that in the group without pelvic adhesions [8.3%(15/180) vs 3.4%(8/235), P<0.05]. Conclusion The incidence of complications in laparoscopic myomectomy was higher than that in laparoscopic hysterectomy. When patients were without pelvic adhesions or with uterine volume< 600 cm3, laparo?scopic surgery present least complication.

Objective To evaluate the possibility of diffusion tensor imaging(DTI)in detecting and quantifying the Wallerian degeneration of optic radiation in occipital lobe chronic infarction.Methods 20 patients with unilateral occipital chronic infarction were undergone DTI.Quantitative fractional anisotropy(FA)and mean diffusivity(MD)were obtained from the ipsilateral optic radiation of the occipital lobe infarction and compared with that of contralateral region using the independent samples t-test.Results On the three dimensional color-coding tensor fractional anisotropic map,the regions of occipital lobe chronic infarction were markedly low signal intensity,the FA value and MD value were 0.274?0.062 and(1.226?0.372)?10-3mm2/s,while in the contralateral region of optic radiation,FA and MD values were 0.495?0.035 and(0.775?0.070)?10-3mm2/s respectively,there was significant difference in FA and MD values in comparing both side(P〈0.01).Conclusion DTI can detect and quantify the Wallerian degeneration in optic radiation after occipital lobe chronic infarction.
