Objective To investigate the state of perceived stigma,self-efficacy and quality of life of patients with mental disorders,and analyze the relationship among these variables,and explore the mediating effect of self-efficacy between the perceived stigma and quality of life.Methods Totally 406 patients with mental disorders were assessed with the Perceived Devaluation-Discrimination Scale (PDDS),Self-efficacy Scale (SES) and Schizophrenia Quality of Life Scale (SQOLS).Results The average score of PDDS was (2.44±0.36).The average score of GSES was (25.75±7.31).The perceived stigma,self-efficacy and quality of life were significantly correlated with each other.The self-efficacy played a mediating role between perceived stigma and quality of life.Conclusions The self-efficacy is the intermediary variable of perceived stigma and QOL of patients with mental disorders.

Objective To study the application of pediculated skin flaps in the treatment of com-plicated long urethratresia. Methods From March 1999 to May 2006, a total of 18 male patients with complicated long urethratresia were treated by using the pediculated skin flaps. The causes of urethratresia were 7 cases of postoperative pelvic fractures with posterior urethral stricture, 4 cases of transurethral intravesical chemotherapy, 3 cases of postoperative bulbar urethral stricture, 2 cases of gonorrhea, and 2 cases of long-time urethral catheter placement. Four cases were urethratresia nf cor-pus penis, 7 cases were anterior urethral obliteration, 7 cases were posterior urethral and anterior ure-thral obliteration. Urethro-perineal fistulas were found in 8 cases, posterior urethrorectal fistulas in 7 cases, false passage formations in 8 cases. The average length of urethratresia was 15.1 cm (range 8. 7 to 23. 0 cm). The urethral scar was rasected, the posterior urethrorectal fistula was repaired, and different kinds of pediculated skin flaps depending on the length of urethratreaia was used. Results All the patients were followed up for 12 to 18 months (mean 14 months). Fifteen patients voided well 3 months postoperatively, none of the urography showed stricture. The mean peak urinary flow rate was 16. 9 ml/s (range from 16. 5 to 21.7 ml/s). Of the other 3 cases, 1 case experienced difficult voi-ding due to the long and circuitous tabularized skin flap but recovered after proper shortening;1 case had restenosis for the infection of anastomosis but voided well after excision and reanastomnsis;1 casehad a urinary fistula resulting from hematoma and infection, but was successfully treated by the neo-plasty of the urinary fistula. The mean peak urinary flow rate was 17.0 ml/s (range 15.0 to 22.0 ml/s) for 17 patients 6 months postoperatively, except for one who experienced genuine urinary incon-tinence. At 9-18 months after operations, the mean peak urinary flow rate was 17.5 ml/s (range 15.8 to 22.5 ml/s) for 17 patients. Conclusion The single-stage urethroplasty based on pediculated skin flaps is a reliable and durable method for complicated long urethratresia.

Objective: To explore the effects of various forms of prostatic apex on positive apical margin rate (PAM) and biochemical recurrence (BCR) after laparoscopic radical prostatectomy. Methods: A retrospective analysis of 309 patients (aging (65±6) years) who were experienced laparoscopic radical prostatectomy from January 2010 to December 2016 at the Department of Urology, First Affiliated Hospital of Fujian Medical University. According to the relationship between prostate apex and membrane urethra at the mid-sagittal plane of preoperative MRI, all patients were classified into 4 categories. There were 31 patients for type 1, apex covering both anterior and posterior aspects of membranous urethra, 139 patients for type 2, apex covering anterior side of membranous urethra, 63 patients for type 3, apex covering posterior aspect of membranous urethra, 76 patients for type 4, apex not covering membranous urethra. PAM and BCR after operation were compared between this four groups respectively. The χ² test was used to compare PAM among the 4 types. Logistic regression analysis were undertaken to analyze the factors affecting PAM. Cox′s proportional hazards regression model was undertaken to identify the variables influencing BCR. Results: There was no significant difference in the 4 groups concerning age, body mass index, prostate volume, preoperative prostate-specific antigen (PSA) value, postoperative Gleason score and pathological stage (P>0.05).The median follow-up time was 32 months (ranged from 12 to 60 months).The data showed that the apical type 3 patients has the highest PAM. There was statistical difference among the 4 groups in PAM (χ²=15.592, P=0.001). Preoperative level of PSA (OR=20.356, 95% CI: 2.440 to 169.810, P=0.005), postoperative Gleason score (OR=4.113, 95% CI: 1.911 to 8.849, P=0.001), pathological stage (OR=3.422, 95% CI: 1.600 to 7.319, P=0.002) and apical type 3 (OR=6.134, 95% CI: 2.196 to 17.132, P=0.001) were independent relactive factors of PAM. Preoperative level of PSA (HR=1.362, 95% CI: 1.006 to 1.843, P=0.045), postoperative Gleason score (HR=1.920, 95% CI: 1.384 to 2.665, P=0.001), pathological stage (HR=1.476, 95% CI: 1.098 to 1.983, P=0.010), PAM (HR=3.497, 95% CI: 2.407 to 5.081, P=0.001)and apical type 3 (HR=1.828, 95% CI: 1.266 to 2.639, P=0.001) were independent prognosis factors of BCR. Conclusion Prostate apical type 3 could be a significant independent predictor of PAM, and an independent prognosis factor for BCR.

AIM:To investigate the role of Rho-associated kinase ( ROCK) inhibitor fasudil in the formation of rabbit urethral stricture after injury and to observe the cell activity , migration and extracellular matrix synthesis in the rabbit urethra fibroblasts.METHODS:The rabbit model of urethral stricture was established by microsurgical techniques .The rabbits were divided into sham operation group , operation group and fasudil (3 mg/kg, 10 mg/kg, 30 mg/kg) groups.The diameter of the stenosis was measured by retrograde urethrography 3 months after surgery .The fibroblasts were isolated from urethral scar, and then incubated with fasudil (12.5 μmol/L, 25 μmol/L, 50 μmol/L) in the presence of transforming growth factor-β1 (TGF-β1, 10 μg/L).The untreated cells were used for control .The cell activity was measured by MTT assay.The cell migration ability was tested by the method of Transwell chambers .The protein expression of ROCK , α-smooth muscle actin (α-SMA) , collagen I and collagen III was determined by Western blot analysis .RESULTS:Fasudil significantly reduced formation of urethral stricture after injury (P<0.05).Cultured rabbit fibroblasts with different con-centrations of fasudil inhibited the cell activity and cell migration ability (P<0.05).The protein expression of ROCK,α-SMA, collagen I and collagen III was also inhibited by treatment with fasudil in a dose -dependent manner ( P<0.05 ) . CONCLUSION:Fasudil inhibits the formation of extracellular matrix and reduces the incidence of urethral stricture after injury by down-regulating TGF-β1-induced Rho/ROCK pathway activation in the rabbit urethra fibroblasts .

Objective To analyze the risk factors of socio-demographic and clinical characteristics related to sui?cidal attempt in major depressive disorder (MDD) patients with anxious characteristics. Methods Based on the anxious module of Mini International Neuropsychiatric Interview (MINI), a total of 728 anxious MDD patients from 13 major men?tal health centers in China were classified as suicidal and non-suicidal attempt groups. Further analyses regarding risk factors of suicidal attempt in anxious MDD patients were performed by the multivariate logistic regression analysis. Re?sults Among the 728 patients with anxious MDD analyzed, 135 (18.5%) of them had suicidal attempt and 593 (81.5%) had non-suicidal attempt. Compared to the non-suicidal attempt group, patients with suicidal attempt had significantly earlier age onset[(32.3 ± 11.9) vs. (35.3 ± 13.1)], more lifetime depression episodes (median:2 vs. 2), more number of ad?missions (median: 1 vs. 0), more frequent depressive episodes (14.8% vs. 7.4%), more atypical characteristics (25.9%vs.15.0%), more suicidal ideation (78.5%vs. 50.3%) and more antidepressant use (81.5%vs. 71.2%). Logistic regression analysis showed that number of admissions (OR=1.18, 95%CI:1.02~1.37), frequent depressive episodes (OR=2.10, 95%CI:1.14~3.68), depressive episodes with suicidal ideation (OR=3.55, 95%CI:2.28~5.54) were associated with suicidal at?tempt in MDD patients with anxious characteristics (P<0.05). Conclusions More number of admissions, more frequent depressive episodes, comorbid suicidal ideation may be risk factors of suicidal attempt in anxious MDD patients.

Objective:To compare the suicidality risk in major depressive disorder (MDD)patients with and without anxious characteristics,and analyze the risk factors of suicidality in MDD patients. Methods:This was a secondary analysis of the data from the Diagnostic Assessment Service for people with Bipolar Disorders in China (DASP),which was initiated by the Chinese Society of Psychiatry (CSP),from September 1,2010 to February 28, 201 1. Based on the anxious module and suicide module of Mini International Neuropsychiatric Interview (M. I. N. I),1 172 MDD patients were classified as suffering from anxious MDD (n=728,62. 1%)and non-anxious MDD(n=444,37. 9%). Logistic regression was employed to examine the risk factors of suicidality in MDD pa-tients. Results:Among the anxious MDD patients,331 (45. 5%)of them had suicidality risk. And 54(12. 2%)of non-anxious MDD patients had suicidality risk. Compare to the non-anxious group,the anxious MDD patients had significantly higher suicidality risk (P<0. 00 1 ). Logistic regression analysis showed that more frequent depressive episodes (OR=2. 07 ),depressive episodes with psychotic symptoms (OR=2. 0 1 ),comorbid with anxious charac-teristics (OR=3. 18)or melancholic characteristics (OR=2. 90)were associated with suicidality risk in patients with MDD. Conclusion:It indicates that the anxious MDD patients may have higher suicidality risk than non-anx-ious MDD patients,and more frequent depressive episodes,depressive episodes with psychotic symptoms,comorbid with anxious characteristics or melancholic characteristics may be risk factors of suicidality in patients with MDD.

Objective To explore the attempted suicide risk factors of socio-demographic and clinical charac-teristics in major depressive disorder patients with atypical features (e.g. increased appetite, weight gain and greater time spent sleeping). Methods This was a secondary analysis of the data from the Diagnostic Assessment Service for People with Bipolar Disorders in China (DASP), which was initiated by the Chinese Society of Psychiatry (CSP) and carried out in 13 major mental health centers in China. Totally 179 patients were diagnosed as atypical major depres-sive disorder patients in all 1172 major depressive disorder patients using Diagnostic and Statistical Manual of Mental Disorder, Fourth Edition (DSM-Ⅳ) by psychiatrists. Suicide attempters and nonattempters were grouped base on the interview results of suicidality module of the Mini International Neuro-psychiatric Interview (MINI). Multiple logistic regression were used to assess association between independent variables and attempted suicide in major depressive disorder patients with atypical features. Results The rater of attempted snicide was 23.5% (42/179) of atypical major depressive disorder patients reported prior or current attempted suicide. Compared to nonattempters, attempters had higher levels of suicidal ideation, postpartum depressive episodes, and the use of antipsychotic, mood stabilizers and benzodiazepines (P<0.05). Logistic regression analysis showed that number of admissions (OR=1.73, 95% CI: 1.093~2.740) and depressive episodes with suicidal ideation (OR=3.90, 95%CI: 1.506~10.092) were significantly associat-ed with attempted suicide in atypical unipolar depression patients (P<0.05). Conclusions High number of admissions and high levels of suicidal ideation may be considered as potential risk factors to identify atypical unipolar depression patients at risk for future suicidal behavior.

Objective To analyze the risk factors of socio-demographic and clinical characteristics related to sui?cide risk in misdiagnosed bipolar disorderⅡ(BPⅡ) treated for major depressive disorder. Methods A total of l478 con?secutive major depressive disorder patients were interviewed with the Mini International Neuropsychiatric Interview (MINI) in 13 major mental health centers in China. Of the 1478 patients, 190 patients were diagnosed BPⅡ, who were divided into two groups (nonsuicidal risk and suicidal risk) with the suicidality module of MINI. Logistic regression was performed to evaluate significant risk factors associated with suicide risk in misdiagnosed BPⅡtreated for major depres?sive disorder. Results Of the 190 patients, 116 were in the nonsuicidal risk group and 74 were in the suicidal risk group. In comparison to the nonsuicidal risk group, the suicidal risk group had younger age [(34.45 ± 11.18) vs.(37.23 ± 13.22), P=0.008], earlier age at onset [(26.20 ± 9.16) vs. (30.37 ± 11.59), P=0.007], and more suicidal ideation (82.4%vs. 53.4%, P=0.001). Logistic regression analysis showed that age (OR=0.969,95% CI:0.945~0.993) and depressive epi?sodes with suicidal ideation (OR=4.129,95%CI:2.030~8.397) were significantly associated with suicide risk in patients of misdiagnosed BPⅡtreated for major depressive disorder (P<0.05). Conclusions Younger age, severer suicidal ide?ation may be potential independent risk factors to suicide risk in BPⅡwith misdiagnosed with major depressive disor?der.

Objective To evaluate the predictors of gleason score pathological downgrading after radical prostatectomy in patients with biopsy-proven level 2 of grading groups (Gleason Score 3 + 4 =7).Methods Data of 252 patients,diagnosed with level 2 of grading groups(Gleason score 3 + 4 =7) prostate cancer by biopsy,with subsequent laparoscopic radical prostatectomy,were retrospectively analyzed.The mean age was 64.3,ranged from 46 to 82 years.The average body mass index (BMI) was 23.2 kg/m2,ranged from 15.2 to 30.4 kg/m2.The median prostate volume,transition zone volume(TZV) and transition zone index(TZI) were 48.9 ml (30.3-73.1 ml),21.4 ml(13.5-31.2 ml) and 0.46％ (0.37％-0.58％),respectively.The median value of tPSA,fPSA and PSAD were 1.53 ng/ml(0.67-3.92 ng/ml),9.65 ng/ml (4.13-18.68 ng/ml) and 0.18 ng/(ml · cm3) [0.09-0.50 ng/ (ml · cm3)],respectively.Clinical T stage was also evaluated,including 153 (60.7％) diagnosed as T1e stage,78 (3 1.0％) diagnosed as T2 stage,and 21 (8.3％) diagnosed as T3 stage.There were 58(23.0％) with extracapsular extension,47 (18.7％) patients with seminal vesicle invasion,and 2(0.8％) with lymph node metastasis.Pathological T stage includes 112 (44.4％) diagnosed as T2 stage,55 (21.8％) diagnosed as T3a stage,35 (13.9％) diagnosed as T3b stage,and 50(19.8％) diagnosed as T4 stage.The patients were assigned Prostate ImagingReporting and Data System version 2 scores of 1,2,3,4,and 5 were 45 (17.9％),36 (14.3％),51 (20.2％),68(27.0％)and 52(20.6％),respectively.The patients were categorized into 2 groups with and without pathological downgrading,including downgrade and no downgrade group.Univariate and multivariate logistic regression analysis were done to determine the predictors of pathological downgrading.Results The patients were categorized into downgrade(n =31) and no downgrade group(n =221) of 252 patients.The pathological downgrading was identified in 31 (12.3％).The tPSA,PSAD and PI-RADS scores in patients with downgrade group which were lower than those in without downgrade group (P ＜ 0.05).The logistic regression analysis revealed PI-RADS score was the independent predictor of downgrading(OR =0.364,95％ CI 0.253-0.522,P ＜ 0.01).The area under the ROC curve of PI-RADS score was 0.810 and the diagnostic value was the best.Conclusions These findings suggested that PI-RADS scores was predictor for pathological downgrading after radical prostatectomy in patients with biopsy-proven level 2 of grading groups,reduced PI-RADS score (PI-RADS score ≤ 3) is correlated with increased pathological downgrading after radical prostatectomy.
