Objective To investigate the empathic abilities and the association between empathic abilities and executive function in schizophrenic patients. Methods Empathy with the Interpersonal Reactivity Index-C (IRI-C) and executive function with Wisconsin Card Sorting Test (WCST) , Stroop Color-Word Task (Stroop), Spatial n-back Task (n-back) were applied to 74 schizophrenic patients and 69 healthy controls. Results Compared with healthy controls, schizophrenic patients showed significantly lower total scores ((46. 8 ± 10. 0) vs (51.5 ±9.7), P<0.01),and subscores in Perspective Taking ((9.5 ±4.2) vs (12.2 ±3.9) , P<0. 01), Fantasy ((12.5 ±4.2) vs (15.5 ±3.8), P<0.01) and Empathic Concern((15. 9 ±4.2) vs (17. 3 ±3.4), P< 0.05) ,but higher subscore((8.8 ±5. 1) vs (6.5 ±3.7), P<0.01) in personal distress of IRI-C. A significant difference(P<0.01) were fund on the scores of WCST, Stroop task and n-back task between schizophrenic patients and healthy controls. Pearson correlation analysis showed that the total scores of IRI-C was negatively correlated with the response administered (Ra), the number of responses errors (Re) and non-perseverative errors (nRpe) of WCST (r= -0.293, r= -0.253, r= -0.272, P<0.05) respectively, that empathic concern sub-score of IRI-C was negatively correlated with Ra, Re, perseverative responses (Rp) and perseverative errors (Rpe) of WCST (r= -0.326, r= -0.300, r= -0.294, r= -0.287, P<0.01 -0.05) respectively , but positively correlated with Rfp. of WCST (r=0.279, P<0.05), and that the fantasy subscore of IRI-C was negatively correlated with the reaction time of B part(r= -0.299, P<0.01) and C part (r= -0.322, P<0.01) of the Stroop task. Conclusion Schizophrenics have a general impairment of empathy and executive function,and affective empathy is related to the executive function, suggesting that the impairment of executive function maybe the one of pathological mechanism for the empathic deficit of patients with schizophrenia.

Objective To investigate the association of HLA-DRB31*03,*04 and *11 alleles with alopecia areata(AA)in Han Nationality in East China.Methods Polymerase chain reaction-sequence specific primer(PCR-SSP)method was conducted in 158 Chinese Han patients with AA as well as in 172 healthy human controls in East China.The relationships of HLA-DRB1 polymorphism to age of onset,episode frequency,clinical course,family history,and severity of AA were evaluated.Results No significant differences were observed for the frequency of HLA DRB1*03,*11 alleles between the patients and human controls,while increased frequency of HLA-DRB1*04 was observed in patients(OR=1.99,Pc=0.01).Multiple logistic regression analysis revealed that HLA-DRB1*04 was more prevalent in patients with an onset after 16 years of age(OR=1.94,Pc=0.02),those without family history(OR=1.97,Pc=0.02),those with recurrent AA(OR=2.49,Pc=0.02),those with a clinical course of more than 1 year(OR=2.94,Pc=0.01),those with severe AA(OR=3.53,Pc=0.00)and tbose with single episode of AA(OR=1.83,Pc=0.04)in comparison with the normal human controls.Conclusion This study demonstrates that HLA-DRB1*04 allele is associated with the occurrence and clinical types of AA in Han Nationality in East China.

Objective:To explore the traits of functional connectivity of resting-state networks in patients of schizophrenia with auditory verbal hallucinations (AVH) by using independent component analysis (ICA).Methods:All patients were met the Diagnostic and Statistical Mannal of Mental Disorders,Fourth Edition,Text Revision (DSM-IV-TR) diagnostic criteria for schizophrenia.Thirty schizophrenia patients with frequent AVH (AVH),24 schizophrenia patients without AVH (non-AVH) and 60 healthy controls (HC) matching with age and gender were analyzed by resting functional magnetic resonance imaging.The AVH were assessed by using Hoffman auditory hallucination scale.By using ICA,auditory network (AUN),language network (LAN),salience network (SAN),right front-parietal network (RFP) and default mode network (DMN) were selected as interesting networks for further analyses.Covariance analysis was used to compare the activity and functional connectivity of multiple resting state networks between three groups,and correlation analysis was used to evaluate the relations between abnormalities of brain and the severity of hallucination.Results:Compared to non-AVH,AVH group showed increased activity in left superior temporal gyrus (STG) and left postcentral gyrus (LPG) in the AUN,and showed decreased activity in right anterior cingulate cortex (ACC) in the SAN (P ＜ 0.05,FDR corrected).The severity of AVH group was associated with activity of the left STG (r =0.43,P ＜0.05) and the right ACC (r =-0.48,P ＜0.01).Furthermore,compared to non-AVH group,there were decreased connectivity between LAN and AUN [(-0.29 ±0.21) vs.(-0.16 ± 0.17),P ＜ 0.05,uncorrected],decreased connectivity between SAN and LAN [(-0.09 ± 0.22) vs.(-0.06 ± 0.18),P ＜ 0.05,uncorrected],increased connectivity between SAN and AUN [(0.30 ± 0.18) vs.(0.15 ± 0.24),P ＜ 0.05,uncorrected] in AVH group.Conclusion:There may be aberrant functional connectivities of AUN,LAN and SAN in schizophrenia patients with frequent AVH,and the occurrence of AVH seems to be related to brain areas involved in language production,speech perception and self-monitoring.

Objective To investigate the prevalence and pattern of androgenetic alopecia (AGA) in Shanghai through a community-based survey. Methods A cluster sampling survey was done among the residents in Beixinjing Community, Changning District, Shanghai. All the subjects were asked to fill a questionnaire to provide their general information, including sex, age, native place, physical status, life habit, family history, etc. The diagnosis of AGA was made by dermatologists. To determine the pattern of hair loss,Norwood-Hamilton classification system and Ludwig classification system were used for male AGA and female AGA, respectively. All the data were statistically analyzed by EpiData and SPSS11.5 software. Results Totally, 7056 subjects completed the questionnaire, including 3519 males and 3537 females, and the response rate was 72.5%. AGA was diagnosed in 809 patients, consisting of 701 males aging from 19 to 91 years (mean 64.16±11.9 years) and 108 females aging from 35 to 91 years (mean 70.46±18.89 years). The standardized prevalence (SP) was 9.47% in total, 15.73% in males and 2.73% in females; the difference was significant between males and females (χ2=356.00, P<0.001). A family history of AGA was observed in 52.7% of all subjects including 391 (55.78%) males and 35 (32.41%) females. Type Ⅲ vertex involvement was the most common type in men aging from 20 to 70 years old, and type Ⅵ in those over 70 years old. Grade Ⅰ and Ⅱ predominated in female AGA. Conclusions The results of this survey indicate that the prevalence of AGA is remarkably higher in men than that in women. Furthermore, the prevalence is steadily increased with advancing age in Shanghai.

Objective To investigate the relationship of the expression of peripheral T helper type 9 (Th9) cells and their related cytokines with the severity and clinical course of alopecia areata,and to explore their significance in the occurrence of alopecia areata.Methods From May to December in 2017,74 outpatients with alopecia areata enrolled from Department of Dermatology,Huashan Hospital,Fudan University served as the alopecia areata group,and 57 health checkup examinees in Huashan Hospital served as the control group.Peripheral blood samples were obtained from the patients and controls.Enzyme-linked immunosorbent assay (ELISA) was performed to detect the serum levels of interleukin (IL)-9,IL-4,transforming growth factor (TGF)-β1 and interferon (IFN)-γ,flow cytometry to determine the proportion of Th9 cells (CD4+IL-9+ T helper cells) in peripheral blood mononuclear cells (PBMC),and real-time fluorescence-based quantitative PCR to measure the mRNA expression of IL-9 and PU.1 in the PBMCs.Data were recorded in Microsoft Excel 2017 software,and statistically analyzed with SPSS17.0 software using two-sample t test and Spearman rank correlation analysis.Statistical charts were drawn with Graphpad prism 6 software.Results Compared with the control group,the alopecia areata group showed significantly decreased serum level of IL-9 (190.40 ± 12.33 ng/L vs.288.10 ± 17.38 ng/L,t =4.71,P ＜ 0.01),but significantly increased serum levels of TGF-β1 (6 191.00 ± 355.50 ng/L vs.4 026.00 ± 258.00 ng/L,t =4.41,P ＜ 0.05) and IFN-γ(15.71 ± 3.00 ng/L vs.8.79 ± 0.60 ng/L,t =2.001,P ＜ 0.05).However,there was no significant difference in the serum level of IL-4 between the alopecia areata group and control group (P ＞ 0.05).The serum level of IFN-γ was significantly lower in the patients with severe alopecia areata than in the patients with mild alopecia areata (P =0.02),and the serum level of IFN-γ in the patients with alopecia areata was negatively correlated with the severity of alopecia tool (SALT) score (ru =-0.298,P =0.010).There were no significant differences in the serum levels of IL-9,IL-4 and TGF-β1 between the patients with severe alopecia areata and those with mild alopecia areata (all P ＞ 0.05).The serum levels of IL-9,IL-4,TGF-β1 and IFN-γdid not differ between the patients with active alopecia areata and those with stable alopecia areata,as well as between the patients with clinical course of ＜ 6 months and those with clinical course of ＞ 6 months (P ＞ 0.05).The alopecia areata group showed significantly decreased proportion of Th9 cells in the PBMCs (t =2.04,P =0.045) and mRNA expression of IL-9 and PU.1 (t =2.12,2.178,both P ＜ 0.05) compared with the control group.Condusion The serum level of IL-9 and proportion of peripheral blood Th9 cells both decrease in patients with alopecia areata,and Th9 cells and their related cytokines may be involved in the occurrence of alopecia areata.

Objective:To review the clinical effect of oral mucosa prefabricated urethra in the treatment of complicated hypospadias in adult patients.Methods:A retrospective analysis was performed on adult patients with complicated hypospadias who underwent two-stage surgical repair in the Second Department of Plastic Surgery, Plastic Surgery Hospital, Chinese Academy of Medical Sciences from January 2011 to December 2020. In the first stage, the urethra was prefabricated with oral mucosa, which was 5.0-6.0 cm in length and 1.0-1.2 cm in width. The second stage was urethral anastomosis, in which scrotal flap was applied to cover the wound. Postoperative follow-up was conducted by telephone or WeChat, including penile appearance and the situation of urination.Results:A total of 114 patients were enrolled, age raging from 18 to 63 years old, with an average age of 28 years. There were 22 cases who had underwent one previous repair operation, 69 cases had two repair operations, and 23 cases had three repair operations. The time from the last operation was 6 months to 60 months, with an average of 25 months. Postoperative complications included urinary fistula in 36 cases, urethral orifice stenosis in 52 cases and penile scar in 58 cases. The scrotal septal skin flap was used in 46 cases and scrotal fascia flap was used in 68 cases. The flaps size ranged from 1.2 cm×3.0 cm to 3.0 cm×5.5 cm. Among the 114 patients, 6 patients were complicated with urinary extravasation, which healed spontaneously in 2-4 weeks; 2 patients developed urinary fistula due to blood supply disorder at the distal end of the scrotal flap, which was repaired half a year later. Other patients healed well. 94 patients were followed up for 6-84 months, with an average of 37 months. All patients had no chordee, smooth urination, no urethral stricture and fistula. All patients were satisfied with the appearance of the penis. Urethral ultrasound and magnetic resonance hydrography were performed in 18 patients. The results showed that the reconstructed urethra was smooth, the mucosa graft had good extension, and there was no residual urine in the urethra.Conclusions:Oral mucosa prefabricated urethra could be used for repair hypospadias in adult patients who failed in repair surgeries, and could obtain good clinical effect.
