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 serum cytokine levels and cognitive impairment in patients with bipolar I manic episode.Methods:Forty-four patients with bipolar I manic episode (BDI group) and 42 healthy volunteers (HC group) matched with demographic data were included.Peripheral serum interleukin-6 (IL-6), interleukin-10 (IL-10), interleukin-23 (IL-23), and tumor necrosis factor-α (TNF-α) levels were detected by enzyme-linked immunosorbent assay (ELISA). The repeatable battery for the assessment of neuropsychological status (RSPM) was used to evaluate the cognitive function of the two groups.Young manic rating scale (YMRS) was used to evaluate the clinical manic symptoms of patients.Hypothesis testing and correlation analysis were processed by SPSS 22.0.Results:(1) The expression levels of serum cytokines IL-6, IL-10, IL-23 and TNF-α in BDI group ((38.872±7.803), (33.259±7.260), 42.350(33.600, 55.390), (108.309±19.398)) were significantly different with those in HC group ((24.664±6.083), (29.257±5.208), 17.360(12.870, 30.690), (68.674±13.610)), and the differences were statistically significant (( t=9.387, t=2.947, Z=-5.477, t=10.921, all P<0.01)). (2) In the RBANS cognitive test, the visual span, attention, delayed memory and total scale scores of the BP group ((92.909±16.126). (83.091±8.529), (80.636±9.592), (416.318±33.438)) were significantly different with those of the HC group ((82.905±10.958), (92.381±14.850), (93.714±7.613), (436.905±37.228), t=3.378, t=-3.538, t=-6.982, t=-2.700, all P<0.05). (3)Correlation analysis showed that in the BDI group, the course of disease was positively correlated with IL-6 and IL-23( r=0.509, r=0.298, P<0.05), the visual breadth was positively correlated with IL-10 and TNF-α ( r=0.426, r=0.647, P<0.05), language was negatively correlated with IL-23 level ( r=-0.372, P<0.05), attention was significantly negatively correlated with IL-6, IL-10, and TNF-α ( r=-0.315, r=-0.318, r=-0.498, all P<0.05), delayed memory was positively correlated with IL-10 and TNF-α ( r=-0.360, r=-0.621, P<0.05). No significant correlation was found between YRMS score, immediate memory score and cytokines ( P>0.05). Conclusion:Patients with bipolar I disorder manic have changes in serum levels of cytokines and cognitive dysfunction. The course of disease and cognitive function are related with serum cytokine level.

Objective To investigate the differences of gut microbiota in patients with schizophrenia between onset and remission. Methods Twelve patients with schizophrenia in the stage of onset were selected as the episode group. Thirteen gender-, age-and BMI-matched patients with schizophrenia during the remission period were selected as the control group. The fecal specimens of the two groups were collected for high-throughput sequencing of the 16S rRNA gene, and the gut microbiota differences between the two groups were analyzed. Results The chao index and ace index of gut microbiota was lower in the episode group than in the control group (t=2.385,P=0.026; t=3.068,P=0.005). The relative abundance of Bacteroides was higher and the relative abundance of Prevotella was lower in the episodes group than in the control group (Z=-2.013, P =0.044; Z=-3.427, P=0.001). The relative abundance of the Prevotella was negatively correlated with the PANSS score (r=-0.577, P=0.003). Conclusion Schizophrenia in the stage of acute episode have altered gut microbiota compared with those in the stage of remission and the gut microbiota is significantly corrected with mental symptoms.
