Objective To investigate the relationship between alexithymia and event-related potential P300 in patients with somatoform disorders.Methods Forty-two patients aged 18 to 65 years fulfilling ICD-10 diagnosis criteria for somatoform disorders were recruited as experiment group.Forty normal healthy persons were selected as control group.The Toronto alexthymia scale-20 (TAS-20) was employed to investigate the alexithymia of the subjects.P300 potentials was employed to investigate the cognitive ability of the subjects.A comparison was made between the patients and the healthy subjects.Results The latencies of N1,P2,N2 and P3 were significantly longer in patients with somatoform disorder than those in the normal controls (P < 0.05 or 0.01),the amplitudes of N2 and P3 were significantly lower in the patients (P < 0.05 or 0.01).The three factors scores and the total score of TAS-20 test in patients with somatoform disorder were significantly lower than those in the normal controls (P < 0.05 or 0.01).There was significant correlation between the latency and the three factors scores and the total score of TAS-20 as well as between the amplitude of P300 and the three factors scores and the total score of TAS-20:the latencies of N1,P2,N2 and P3 recorded at Pz was positively correlated with the factors scores (r =0.32 ~ 0.48,P < 0.05 or 0.01),and the amplitudes of N1,P2,N2 and P3 recorded at Pz was negatively correlated with theTAS-20 scores (r=-0.31 ~-0.51,P<0.05 or0.01).Conclusions There existed significant correlation between the alexithymia and cognitive impairment in patients with somatoform disorders.Both alexithymia and event-related potential P300 can be used as a clinical evaluation index for patients with somatoform disorder.

Objective:To evaluate the short-term prognostic value of model for end-stage liver disease (MELD) combined with high density lipoprotein-cholesterol (HDL-C) in patients with hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF).Methods:From December 2015 to December 2018, 182 patients with HBV-ACLF who were treated in Henan Provincial People′s Hospital were included. Prognosis and clinical data including HDL-C, total bilirubin, international standardized ratio (INR), creatinine of patients within 24 hours after admission were collected and analyzed retrospectively.The values of MELD were calculated. The binary logistic regression analysis was used to analyze the independent risk factors affecting 90-day mortality in HBV-ACLF patients.The receiver operator characteristic curve (ROC) and MedCalc 15.2 software were used to assess the predictive value of MELD, HDL-C and MELD-HDL-C model for prognosis. Kaplan-Meier survival curve was performed to analyze the prognosis of patients in different groups.Results:Sixty patients were divided into the death group and 122 patients were divided into the survival group according to the prognosis during hospitalization and 90 days after discharge. The MELD score of patients in the survival group was 21(19, 24), which was significantly lower than that in the death group (29(25, 34)), and the HDL-C value of patients in the survival group was significantly higher than that in the death group (0.3 (0.1, 0.6) mmol/L vs 0.2(0.1, 0.5) mmol/L). The differences were both statistically significant ( Z=-6.290 and -4.087, respectively, both P<0.01). Multivariate logistic regression analysis showed that MELD score and HDL-C value were the independent risk factors for 90-day mortality in patients with HBV-ACLF(odds ratio ( OR)=1.432, 95% confidence interval ( CI)1.271-1.613; OR=0.584, 95% CI 0.487-0.700, respectively; both P<0.01). Areas under the ROC of MELD, HDL-C and MELD-HDL-C scoring models were 0.775, 0.782 and 0.878, respectively. MELD-HDL-C scoring model was superior to both MELD and HDL-C , and the differences were both statistically significant ( Z=3.944 and 3.104, respectively, both P<0.01). When the MELD-HDL-C Youden′s index was set at 0.72, the optimal threshold was 24.69. Patients with MELD-HDL-C score≥24.69 had lower survival rate than patients with MELD-HDL-C score<24.69, and the difference was statistically significant ( χ2=142.900, P<0.01). Conclusion:MELD, HDL-C and MELD-HDL-C scoring systems could predict the short-term prognosis in patients with HBV-ACLF, and the predictive value of MELD-HDL-C has the superiority.

Objective To investigate the virological response in hepatitis C virus (HCV)genotype 1b relapsers after 48 weeks of peginterferon/ribavirin (peg-IFN/RBV)combination retreatment,and to explore the predictive value of interleukin (IL )-28B rs12978960 genetic polymorphismon virological response.Methods From 2012 to 2014,genotype 1b chronic hepatitis C (CHC)relapsers in He′nan Provincial People′s Hospital were retreated with combined peg-IFN/RBV for 48 weeks and followed up for 24 weeks off-treatment.Host IL-28B genetic polymorphism was detected.Predictive factors associated with virological response and sustained virological response (SVR)were analyzed.Independent-samples t test was conducted in continuous variables,whileχ2 test or Fisher exact probability test was conducted in counts data.Results A total of 61 patients finished 48 weeks of peg-IFN/RBV combination therapy and were further followed up for 24 weeks off-treatment.Mean age was (46.7 ±12.4)years.Thirty-seven patients (60.7%)were male and 49 were rs12978960 CC genotype.After 48 weeks of retreatment with peg-IFN/RBV and 24 weeks of off-treatment follow-up,40 patients (65 .6%)achieved SVR.Rapid virological response (RVR)and SVR of younger patients were both significantly higher than those of older patients (100.0% vs 67.4% and 85 .0% vs 47.6%,respectively;both P =0.006).IL-28B rs12978960 genotype was predictive to RVR and SVR.Patients with RVR and SVR had higher carriage rates of IL-28B rs12978960 CC genotype compared with those without RVR and SVR (both P <0.05 ).Patients with CC genotype had higher rates of RVR (34.1 % vs 0;χ2 = 10.625 ,P =0.006 ),end-of-treatment virological response (84.1 % vs 70.6%;χ2 =5 .563,P =0.039 )and SVR (77.3% vs 35 .3%;χ2 =9.572,P =0.007)than those with CT/TT genotype.However,there were no statistical differences of extended RVR (34.1 % vs 29.4%;χ2 =0.122,P =0.809)and early virological response (79.5 % vs 82.3%;χ2 =0.612,P =0.964).Conclusions Retreatment with antiviral therapy is necessary in CHC patients with genotype 1b. IL-28B rs12978960 genetic polymorphism is predictive to the SVR of retreatment,especially for patients without RVR,which will provide individualized treatment and optimize the treatment strategy.

Objective To investigate the social cognition and its correlation with social function for attenuated psychosis syndrome (APS). Methods From August, 2014 to December, 2015, 39 patients with APS were recruited as research group. Another 40 normal healthy persons with similar gender, ages, and education levels were selected as control group. The Faux Pas Recognition Test (FPR) and Yoni Task Test were used to evaluate the social cognition, and Social Disability Screening Schedule (SDSS) was used to evaluate the social function. The correlation between FPR, Yoni Task Test and SDSS in the research group was analyzed. Results In FPR test, the faux pas questions score, control questions score and total score of FPR were significantly lower in the research group than in the normal control group (t>2.378, P<0.01). In Yoni Task Test, the cognitive theory of mind total score (Cog), cognitive theory of mind first-level score (Cog1) and cog-nitive theory of mind second-level score (Cog2), and affective theory of mind total score (Aff), affective theory of mind first-level score (Aff1) and affective theory of mind second-level score (Aff2) were significantly lower in the research group than in the normal control group (t>2.341, P<0.01). There was no significant difference in control theory of mind total score (Phy), control theory of mind first-level score (Phy1) and control theory of mind second-level score (Phy2) between two groups (t<1.430, P>0.05). The SDSS total score was signifi-cantly higher in the research group than in the normal control group (t=13.032, P<0.001). In the research group, FPR's faux pas questions score and FPR's total score were negatively correlated with SDSS score (r>0.473, P<0.01); in Yoni task test, Cog's total score and factor scores, Aff's total score and factor scores were negatively correlated with SDSS score (r>0.448, P<0.01). Conclusion Social cognition func-tion in APS is impaired. It is associated with social dysfunction in APS.
