Objective To explore the effect of amisulpride and risperidone in the treatment of patients with first-episode schizophrenia and its influence on social function.Methods 70 patients of schizophrenia conformed to the International classification of diseases tenth edition(ICD-10) were randomly divided into amisulpride group(observation group,35 cases) and risperidone group(control group,35 cases) by using the random number table method.The Positive and Negative Scale(PANSS) was used to evaluate the efficacy,the Scale of Social Function in Psychosis Inpatients(SSPI) was used to evaluate social function before and after 8 weeks of treatment.Results After 8 weeks treatment,the negative symptom factor score of the PANSS in the observation group was (15.04±3.55)points,which was improved significantly compared with (17.82±3.87)points in the control group,the difference was statistically significant(t=3.132,P<0.05).The scores of the field in movement and interaction,social activities and skills factor score and the total score of SSPI in the observation group were (15.49±3.54)points,(14.53±4.25)points,(39.25±8.27)points,respectively,which in the control group were (12.78±3.29)points,(10.01±3.78)points,(33.72±7.83)points,respectively,the differences between the two groups were statistically significant (t=3.317,4.701,2.873,all P<0.05).Conclusion Amisulpride is effective in improving the negative symptoms,social function in patients with schizophrenia,and the effect is better than risperidone.

Objective To investigate the relationship of preoperative level of serum anterior gradient 2 (AGR2)with clinicopathological features and prognosis of patients with prostate cancer. Methods The serum levels of AGR2 were detected by ELISA in 72 patients with prostate cancer, 30 patients with benign prostatic hyperplasia (BPH) and 20 healthy controls. The receiver operating characteristic (ROC) curve was drawn to determine the optimal cut-off value of clinical diagnosis, and to analyze the diagnostic value of serum AGR2 in prostate cancer. Kaplan-Meier method was used to plot the survival curve. Log-rank test was used to analyze the difference of survival time between the two groups. The effect of AGR2 on the prognosis of prostate cancer patients was analyzed by Cox regression. Results The level of serum AGR2 in prostate cancer group was obviously higher than those in BPH group and health control group (t=4.441, t=5.285, both P<0.01).Serum AGR2 level was correlated with Gleason score,tumor stage, lymph node metastasis and preoperative PSA level (F=11.343, F=9.613, t=3.882, t=7.514, all P<0.01). The area under the ROC curve(AUC) of AGR2 was 0.803(95%CI 0.726-0.880,P=0.000), when the cut-off value was 17.25 ng/ml, the sensitivity rate was 63.9%, specificity rate was 80.0%. Kaplan-Meier survival analysis showed that the survival rate in low AGR2 expression group was significantly higher than that in high AGR2 expression group (χ 2=5.565, P=0.018). Cox regression analysis showed that AGR2 was an independent risk factor for prostate cancer patients (HR=5.412, 95%CI 1.143-25.624, P=0.033). Conclusions The elevated level of serum AGR2 is related with tumor progression in prostate cancer. It may be a potential marker for predicting prognosis of patients with prostate cancer.

Objective To investigate the diagnostic value of lipocalin 2 (LCN2) combined with prostate-specific antigen (PSA) in prostate cancer (PCa).Methods Enzyme-linked immunosorbent assay (ELISA) was used to determine the levels of serum LCN2 in patients with PCa (PCa group,n =82),patients with benign prostatic hyperplasia (BPH group,n =40) and healthy subjects (NC group,n =30).The levels of serum PSA were measured by chemiluminescence.The diagnostic value of LCN2 combined with PSA in PCa was analyzed by the receiver operating characteristic (ROC) curve.The relationship between the level of LCN2 and clinical parameters in PCa patients was analyzed.Results The levels of serum LCN2 in PCa group,BPH group and NC group were (88.97 ±40.83) pg/ml,(53.12 ±25.66) pg/ml,(13.34 ±4.86) pg/ml (F=61.306,P ＜0.001).The level of LCN2 in PCa group was significantly higher than that in BPH group and NC group (both P＜0.001).The levels of serum PSA in PCa group,BPH group and NC group were (17.65 ± 8.43) ng/ml,(11.27 ±3.56) ng/ml,(2.61 ±0.87) ng/ml (F=60.959,P＜0.001).The level of serum PSA in PCa group was significantly higher than that in BPH group and NC group (both P ＜0.001).There was positive correlation between serum LCN2 and PSA levels (r =0.360,P ＜ 0.001).The levels of serum LCN2 in PCa patients with different Gleason score,TNM stage and distant metastasis were significantly different (F =8.546,P ＜ 0.001;t =3.421,P =0.001;t =3.622,P =0.010).The area under the curve (AUC) of serum LCN2 was 0.763 (95％ CI:0.677-0.850,P ＜0.001).The sensitivity and specificity of serum LCN2 were 62.2％ and 85.0％.The AUC of PSA was 0.750 (95％ CI:0.665-0.836,P ＜ 0.001).The sensitivity and specificity of serum PSA were 51.2％ and 87.5％.The AUC of LCN2 combined with PSA was 0.822 (95％ CI:0.749-0.895,P ＜0.001).Conclusion Serum LCN2 level in the patients with PCa is significantly higher,which participates in tumor invasion.LCN2 may be a potential serum marker for the diagnosis of PCa.Combined detection of LCN2 and PSA contributes to the early diagnosis of PCa.

Objective:To establish a safe, effective, simple, and more economically feasible method to obtain platelet-rich plasma (PRP).Methods:Whole blood was collected from 24 patients with atrophic acne scars on the face. For the preparation of PRP, a slight modification of Choukroun＇s method was used. Enzyme-linked immunosorbent assay (ELISA) was used to measure the levels of platelet derived growth factor-β(PDGF-β), transforming growth factor-β1 (TGF-β1), epidermal growth factor (EGF), vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF), isulin-like growth factor-1 (IGF-1) in normal plasma and PRP.Results:The average concentration of PDGF-β in PRP was (755.61±418.31) ng/L, which was higher than [(479.93±279.18) ng/L] in normal plasma ( t=3.479, P<0.01). The average concentration of TGF-β1 in PRP was (2267.00±1223.68), which was higher than [(1535.50±910.91) ng/L] in normal plasma ( t=7.082, P<0.01). The average concentration of EGF in PRP was (30.70±12.39) ng/L, which was higher than [(20.77±10.31) ng/L] in normal plasma ( t=6.899, P<0.01). The average concentration of VEGF in PRP was (25.42±17.69) ng/L, which was higher than [(12.01±7.77) ng/L] in normal plasma ( t=5.230, P<0.01). The average concentration of bFGF was (17.85±7.17) ng/L, which was higher than [(10.90±4.73) ng/L] in normal plasma ( t=6.050, P<0.01). The average concentration of IGF-1 was (201.22±36.80) ng/ml, which was higher than [(174.90±33.80) ng/ml] in normal plasma ( t=3.760, P<0.01). Conclusions:Compared to normal plasma, modified PRP contains higher levels of growth factors. The modified method is a reliable option for liquid PRP, especially applicable for invasive cosmetic laser surgery to promote wound repair.

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.
