Objective:To analyze the predictive factors of GGU between biopsy and radical prostatectomy pathology based on 2014 ISUP grouping system, then establish and evaluate nomogram.Methods:Patients undergoing radical prostatectomy in Shanghai Ruijin Hospital from March 2012 to March 2019 were reviewed, and the clinical and pathological information were collected. Age(68.1±7.2), body mass indes(BMI) (24.2±3.2)kg/m 2, prostate specific antigen(PSA) 11.5(6.7-20.4)ng/ml, prostate specific antigen destiny(PSAD) 0.35(0.20-0.66). Before March 2017, the number of biopsy cores were 6 to 8; After then, all patients toke 12 cores systemic biopsy. Based on 2014 ISUP grouping system, the differences between biopsy and radical prostatectomy grades were counted. The independent predictors of GGU were analyzed by univariate and multivariate logistic regression analysis, then the nomogram for predicting GGU were established and evaluated. Results:429 patients were enrolled. There were 161 (37.5%) patients in GGU group and 268 (62.5%) patients in non-GGU group. After multivariate logistic regression analysis, body mass index (BMI)>28 kg/m 2( OR=2.54, P=0.021), prostate specific antigen density (PSAD)( OR=1.65, P=0.018)and 2014 ISUP grouping sysyem ( OR=0.53, P<0.001) of biopsy specimen were independent impact factors of GGU. The predicting model was established according to BMI, PSAD and 2014 ISUP grouping system. The area under the ROC cure of the model was 0.735 (95% CI 0.681-0.789). The nomogram model was well calibrated, with the mean absolute error of 6.7%, which means the prediction of GGU is fairly consistent with the actual situation. Conclusions:Based on the 2014 ISUP grouping system, BMI>28 kg/m 2, PSAD and 2014 ISUP grouping of biopsy specimen were independent predictors of GGU. The nomogram model for predicting GGU has a good statistical significance.

Objective To investigate sun protection behavior among middle-aged and elderly women in Beijing.Methods The central (Xuanwumen district) and peripheral areas (Yanqing district) of Beijing city were selected for investigation from May to June in 2016.By random sampling and field investigation,interviewees completed questionnaires with the help of dermatologists.Results A total of 400 females aged 40-90 years were investigated,including 190 in the Xuanwumen district and 210 in the Yanqing district.Among all the subjects,the average duration of outdoor activities was 2 hours.Moreover,117 (29.2%) of the 400 interviewees had the active sun exposure habit,including 38 (18.1%) in the Yanqing district and 79 (41.6%) in the Xuanwumen district,and the proportion of subjects with the active sun exposure habit significantly differed between the two districts (x2 =26.582,P < 0.001).In addition,67 (16.8%) interviewees had a sunburn history,and 130 (32.5%) were used to applying sunscreen.The proportion of sunscreen users was significantly higher in moderately or highly educated women (103 [45.2%]) than in lowly educated women (28/172 [16.3%],P < 0.001).The proportion of sunscreen users in women with skin type Ⅲ (41.2% [70/170]) was significantly higher than that in those with skin type Ⅳ (26.5% [61/230],P =0.002).The scores for facial skin aging and dorsal hand skin aging were both significantly lower in sunscreen users than in non-users (Z =18.536,10.731,P =0.002,0.026,respectively).Conclusion The active sun exposure habit in the middle-aged and elderly women differs between the central and peripheral areas of Beijing,and the use of sunscreen is associated with education level.

Objective To investigate the relationship among Machiavellianism,loneliness and coping style in adolescents.Methods 850 junior middle school students were recruited and assessed with Kiddie Machiavellianism Scale,Self-esteem Scale,and Strengths and Difficulties Questionnaire (for students).Mediating effect was analyzed by multiple regression analysis.Results ① The scores of Machiavellianism,loneliness,positive coping and negative coping were (37.35±7.52),(30.21 ± 10.72),(21.07±6.12) and (9.44± 3.84) respectively.② Machiavellianism was positively correlated with negative coping style (r=0.192,P<0.01) and loneliness (r=0.263,P< 0.01),as well as negatively correlated with positive coping style (r=-0.244,P<0.01).③ Positive coping style partially mediated the effect of Machiavellianism on loneliness,and the mediating role accounted for 37.72% for the whole effect.Conclusion The higher the Machiavellianism is,the more serious the loneliness is.Positive coping style partially mediates the relations between Machiavellianism and loneliness.
