Schizophrenia (SZ) stands as a severe psychiatric disorder. This study applied diffusion tensor imaging (DTI) data in conjunction with graph neural networks to distinguish SZ patients from normal controls (NCs) and showcases the superior performance of a graph neural network integrating combined fractional anisotropy and fiber number brain network features, achieving an accuracy of 73.79% in distinguishing SZ patients from NCs. Beyond mere discrimination, our study delved deeper into the advantages of utilizing white matter brain network features for identifying SZ patients through interpretable model analysis and gene expression analysis. These analyses uncovered intricate interrelationships between brain imaging markers and genetic biomarkers, providing novel insights into the neuropathological basis of SZ. In summary, our findings underscore the potential of graph neural networks applied to multimodal DTI data for enhancing SZ detection through an integrated analysis of neuroimaging and genetic features.

Objective To explore the changes of pubescent immune response in the schizophrenia offspring induced by poly(I:C) during pregnancy and the effects on white matter.Methods The obtained pregnant rats were randomly divided into model group(n=6) and control group (n=5), receiving either poly (I:C) at a dose of 10 mg/kg diluted in 0.9％ NaC1 solution or vehicle solution alone (sterile pyrogen-free 0.9％ NaC1) on gestation day 9 (GD9).Immunohistochemical technique(IHC) was applied to detect the changes of microglias and astrocytes in the prefrontal cortex(PFC) and hippocampus(HC) of partly offsprings in the two groups at the sixth week,as well as Luxol fast blue(LFB) for the changes of white matter.The other offsprings of each group were selected for behavioral assessment at the eighth week.Results The results of prepulse inhibition test showed that PP2, PP4 and PP8 of model groups were significantly lower than that of the control group at young adult(P＜0.01).In passive avoidance test, and the T1 results of model group were significantly higher than those of the control group, the T results of model group were lower than those of control group (P＜ 0.01).Immunohistochemical results indicated that the number of microglias in the model group((264±33)/mm2, (271 ±38)/mm2) was significantly increased in PFC and HC than that in the control group((140±29)/mm2, (169±37)/mm2, P＜0.05) ,which was accompanied with significant morphological changes, while the OD value of astrocyte protein expression in the frontal lobe and hippocampus had no obvious difference between the model group and control group(P＞0.05).The OD value of LFB staining for myelin in the model group(0.29±0.02) was significantly decreased compared with that in the control group(0.33±0.03)(P＜0.01).Conclusion The young adult offsprings with prenatal infection present obvious schizophrenia-like behavior, meanwhile, the microglias activation and demyelination changes in white matter are observed,which provides more evidence for the relationship between immune response and white matter in the pathogenesis of schizophrenia.

Objective By analyzing the changes in behavior and the myelin basic protein (MBP) of the offspring in adult that treated with Poly(I∶C) during pregnancy,and to understand the role of white matter abnormalities in the abnormal behavior of the offspring induced by infection in maternal hosts.Methods Two models maternal female rats were given Poly(I∶ C) with 5 mg/kg and 10mg/kg respectively during the early pregnancy,and control maternal female rats was administered 5 mg/kg saline.The prepulse inhibition test,passive avoidance test and active avoidance test were used to evaluate schizophrenia like behaviors for each groups offspring in 8 weeks,and the expression of MBP was detected by immunohistochemical staining methods.Results The results of prepulse inhibition test showed that significant differences of PP2,PP4 and PP8 results existed among control group,single-dose model group and double-dose model group (F=10.381,P=0.001,F=10.313,P=0.001,F=15.233,P=0.000).Compared with the control group,the two model groups showed significantly lower,the double-dose model group was lower than single-dose model group (P＜0.05).In passive avoidance test,there were significant differences of T1 and T2 results existed among control group,single-dose model group and double-dose model group (F=23.555,P=0.000,F=17.524,P=0.000).The T1 results of two model groups were significantly higher than control group,the double-dose model group was significantly higher than single-dose model group (P＜0.05) ; the T2 results of two model groups were lower than control group,the double-dose model group was lower than single-dose model group(P＜0.05).The results of passive avoidance test indicated that significant differences existed among control group,single-dose model group and double-dose model group in whole period of testing and total conditioned response rate(F=8.631,P=0.000,F=6.986,P=0.001),the two model groups were significantly lower than control group,double-dose model group was significantly lower than single-dose model group (P＜0.05).MBP results of two model groups were significantly lower than control group,two model groups had no significant difference (P＞ 0.05).Conclusion The adult offspring that were treated with Poly (I∶C) exit abnormal behavior and damaged white matter,and there is a correlation between the degree of abnormal behavior and drug dose.

OBJECTIVE: To compare the effect of 7 antipsychotic drugs on the life quality of schizophrenia patients including chlorpromazine, sulpiride, clozapine, risperidone, olanzapine, quetiapine, and aripiprazole. METHODS: A total of 1,227 stable schizophrenic patients within 5 years onset who took 1 of the 7 study medications as maintenance treatment were followed up for 1 year at 10 China sites. Patients were evaluated by the short form-36 health survey (SF-36) at the baseline and at the end of 1 year. RESULTS: The life quality was improved obviously at the end of the follow-up. There was significant difference in body pain, vitality, and mental health (P<0.05) among these antipsychotic drugs. CONCLUSION All 7 antipsychotic drugs can improve the life quality of schizophrenia patients. Atypical antipsychotic drugs, especially olazapine and quetiapine, are superior to typical antipsychotic drugs in improving life quality.

OBJECTIVETo explore the changes of soluble interleukin-2 receptor(sIL-2R) in serum and cerebrospinal fluid (CSF) of patients with delayed encephalopathy after acute carbon monoxide poisoning (DEACMP).

METHODSThere were 31 patients with DEACMP, 32 patients with other encephalopathy and 31 controls in this study. The levels of sIL-2R in serum and CSF were detected by ELISA.

RESULTSSerum sIL-2R in patients with DEACMP[(329.21 +/- 160.99)U/ml] was significantly higher than that in control[(115.67 +/- 89.58) U/ml, P < 0.05)], but not significantly different from that in the other encephalopathy group[(367.50 +/- 123.14) U/ml, P > 0.05)]. CSF sIL-2R in patients with DEACMP[(54.48 +/- 43.04) U/ml] measured a little before discharge was significantly lower than that in patients with the other encephalopathy[(110.24 +/- 76.56) U/ml, P < 0.05)], but not significantly different from that in the control group[(34.96 +/- 22.70)U/ml, P > 0.05)]. At the pre-discharged period, CSF sIL-2R in patients with DEACMP[(100.26 +/- 93.65) U/ml] was significantly higher than that at the early stage of hospitalization[(52.28 +/- 43.31) U/ml, P < 0.05)]. No significant difference in serum sIL-2R was found between early stage of hospitalization[(338.34 +/- 161.53) U/ml] and pre-discharge [(351.31 +/- 175.93) U/ml, P > 0.05)].

CONCLUSIONThe occurrence of DEACMP may be related with immunopathological damage. The sIL-2R levels in serum and CSF may give information about the state of immunological function of the patients with DEACMP and may contribute to determining the patient's condition and prognosis.
