Objective @#To explore the difference of serum inflammatory factors in patients with first episode schizo- phrenia , patients with relapse episode schizophrenia and healthy people , and the correlation between serum inflam- matory factors with negative symptoms in patients with schizophrenia , so as to provide reference for clinical inter- vention .@*Methods @#A total of 86 patients with first episode schizophrenia (first episode group) , 80 patients with re- lapse episode schizophrenia ( relapse episode group) and 82 healthy people ( control group) were included in the study. The difference of serum inflammatory factors among the three groups and the correlation between serum inflammatory factors with negative symptoms were analyzed .@*Results @#There were significant differences in serum interleukin (IL) -1βand IL-16 levels among the three groups (P < 0. 05) . The analysis and comparison between the two groups showed that the serum IL-1βin first episode group was significantly higher than that in relapse episode group and control group(P < 0. 05) , serum IL-16 in first episode group and relapse episode group was significantly higher than that in control group(P < 0. 05) . Serum IL-1βwas negatively correlated with PANSS general psycho- pathological scale factor score in first episode group( P < 0. 05) , and serum IL-16 was positively correlated with PANSS negative symptom scale factor score in relapse episode group( P < 0. 05) . IL-16 level might be an inde- pendent risk factor affecting the onset of first episode group and relapse episode group(P < 0. 05) . @*Conclusion@#There are differences in serum levels of IL-1βand IL-16 between patients with schizophrenia and healthy people . Serum IL-16 levels in patients with relapse episode schizophrenia are associated with negative symptoms . IL-16 lev- el may be an independent risk factor for schizophrenia.

Objective:To explore the relationship between the childhood trauma and neruocognition in patients with schizophrenia.Methods:Sixty-two patients with schizophrenic were selected from Anhui mental health center, and sixty-three community health controls were selected. All subjects were assessed with the childhood trauma questionnaire (CTQ), Wisconsin card sorting Test (WCST), attention network test (ANT), verbal fluency test (VFT) and digit span test (DST). SPSS 17.0 was used for statistical analysis. t-test was used to compare the measurement data of normal distribution and Mann-Whitney U test was used to compare the measurement data of non-normal distribution. Spearman correlation analysis was used to analyze the relationship between CTQ score and cognitive function score. Results:Compared with health controls(34.00(30.00, 37.00), 6.00 (5.00, 7.00), 5.00(5.00, 5.00), 5.00(5.00, 5.00), 9.00(6.00, 11.00), 7.00(6.00, 10.00)), the total score of CTQ, subscores of emotional abuse, physical abuse, sexual abuse, emotional neglect and physical neglect in patients with schizophrenia were significantly increased (48.50(37.75, 57.00), 9.00(6.00, 12.25), 7.00(5.00, 9.25), 5.50(5.00, 7.25), 13.00 (9.00, 16.25), 11.00(8.00, 13.00)) ( Z=-4.781--6.724, all P<0.01). Compared with the control group, the number of WCST classification completed in the patient group was lower, while the number of wrong answers, continuous answers and persistent errors increased ( Z=-5.655--6.060, all P< 0.01). The correct rate of ant decreased, but the reaction time increased ( Z=-5.796, -6.094, all P< 0.01). VFT and DST scores were decreased ( Z=-3.492--8.499, both P< 0.01). In patients with schizophrenia, CTQ sexual abuse subscore were negatively correlated with completed categories scores ( r=-0.384) and positively correlated with total errors ( r=0.360), perseverative responses( r=0.394) and perseverative errors ( r=0.381) on WCST(all P<0.01). CTQ physical neglect scores were negatively correlated with the ANT correct ratio( r=-0.400) and conflict resolution( r=-0.417) (all P<0.01). CTQ emotional neglect scores were negatively correlated with VFT scores( r=-0.345) ( P<0.01). The significant associations remained after controlling for age, education and PANSS scores. Conclusion:Patients with schizophrenia experience more traumatic events in their early years and have extensive cognitive defects. The childhood trauma has negative effects on cognitive flexibility, attention, memory and speech function in patients with schizophrenia.However, the positive correlation between childhood trauma and executive conflict of attention network needs to be further verified and explored.
