In recent years,our understanding of neutrophil extracellular traps(NETs)has been deepened with advancements in technology.Extensive research has demonstrated that NETs are intricately linked to autoimmunity and contribute to the path-ogenesis of autoimmune diseases through multiple mechanisms,such as serving as a source of self-antigens,activating the com-plement system,or modulating other immune cells.Notably,the interaction between NETs and immune cells plays a critical role in disease progression.This article primarily reviews the relationship of NETs with dendritic cells,macrophages,B cells,and CD4 T cells in autoimmune diseases,providing insights into potential therapeutic strategies by NETs level modulation and NETs-immune cell interactions intervenion.

Objective To explore the impact of clinical treatment decisions on the long-term survival of different molecular subtypes of locally advanced breast cancer(LABC),and to promote the development of more effective and individualized treatment regimens for LABC.Methods The cases of LABC diagnosed by pathology from 2010 to 2015 were searched in the database.Breast cancer-specific survival(BCSS)and overall survival(OS)were estimated by plotting Kaplan-Meier curves.The log rank test(Mantel-Cox)was used to analyze the difference between the groups,and the benefit population of LABC was determined after for age,TNM stage,grade,treatment methods.Results The 5-year OS and BCSS were 77.43％and 84.34％in breast-conserving,and 68.03％and 76.90％in mastectomy,respectively.The 5-year OS and BCSS of Luminal A LABC were 79.91％and 87.23％in breast-conserving,and 71.78％and 81.16％in mastectomy,respectively.The 5-year OS and BCSS of Luminal B LABC were 79.30％and 83.14％in breast-conserving,and were 70.37％and 76.92％in mastectomy,respectively.The 5-year OS and BCSS of triple-negative LABC were 60.77％and 68.13％in breast-conserving,and those of mastectomy were 47.13％and 55.94％,respectively.The 5-year OS and BCSS of HER2 positive were 75.42％,82.05％in breast-conserving,and were 67.05％and 75.01％in mastectomy,respectively;The 5-year OS and BCSS of triple-positive LABC were 86.12％and 91.63％in breast-conserving,and 74.54％and 82.56％in mastectomy,respectively.The 5-year OS and BCSS of well differentiated and N0 triple-positive LABC patients with chemotherapy were 88.24％and 76.91％,and those of patients without chmotherapy were 88.24％and 90.91％,respectively(BCSS:P=0.812;OS:P=0.311).Conclusion In the selective population,OS and BCSS of patients with LABC undergoing breast conserving surgery were significantly better than those of mastectomy.When OS and BCSS were compared for different molecular types and stages of LABC,breast-conserving surgery was still superior to total mastectomy.LABC could be considered for highly differentiated,N0 stage Triple positive without chemotherapy.

OBJECTIVETo explore the association of a functional polymorphism Val158Met of COMT gene and attention and executive function in first-episode treatment-naive patients with schizophrenia and healthy controls.

METHODSTrail making test (TMT) and clinical performances were evaluated in 103 first-episode treatment-naive patients with schizophrenia and 99 healthy controls. Polymorphism of COMT Val158Met was analyzed using polymerase chain reaction-restriction fragment length polymorphism method. A general linear model was used to investigate the effect of genotype subgroups on the attention and executive function.

RESULTSThere was a significant difference between control subjects and patients with schizophrenia on the TMT-A and B. However, no significant difference among Val/Val, Val/Met and Met/Met on the TMT-A and B in control subjects and patients with schizophrenia was detected.

CONCLUSIONThe association among COMT Met variant and trail making testing (attention and executive function) has been replicated. However, no association of COMT Met variant with disruption of dopaminergic influence on neurocognitive function was detected. This may be due to the heterogeneity of population.

Objective To investigate gray matter structural damage in first-episode antipsychotic-na?ve patients with adolescent-onset schizophrenia. Methods Twenty-six patients with schizophrenia and 26 healthy controls were scanned by using GE 3.0T magnetic resonance imaging in order to explore brain gray matter volume (GMV) changes with registration techniques based on the latest morphological deformation field theory. The correlation of gray matter volume abnormalities with clinical severity was also analyzed. Results Compared with healthy controls, patients with adoles-cent-onset schizophrenia showed significant reduction in GMV in the left parietal lobe, parahippocampal gyrus and right cerebellar pyramis. GMV of the left parahippocampal gyrus is significantly correlated with PANSS paranoid scores (r=-0.49, P=0.02). Conclusions There is structural abnormality in GM in parahippocampal-parietal-cerebellar in pa-tients with adolescent-onset schizophrenia and the severity of paranoid symptoms is related to the reduced GMV in the left parahippocampal gyrus.

ObjectiveTo identify the metabolic alterations on prefrontal lobes and hippocampus in male patients with the first-episode mania using proton magnetic resonance spectroscopy(H-MRS).Method 18 male patients with the first-episode mania and 27 healthy subjects matched for age,gender,and years of education were included in the study.1 H-MRS was performed in two sides of the hippocampus and frontal lobes regions.The ratios of N-acetylaspartate (NAA),choline (Cho) to creatine (Cr) were measured.One-sample t test and paired-samples t test were used for statistic process.ResultsMale patients with the first-episode mania presented decreased NAA/Cr in left frontal lobe and hippocampus regions when compared to normal controls( left frontal lobe (1.68 ±0.19 vs 1.86 ± 0.19),hippocampus ( 1.32 ± 0.10 vs 1.43 ± 0.16 ),P ＜ 0.01 ),but there were no significant difference in NAA/Cr for right frontal lobe and hippocampus regions between groups ( all P ＞ 0.05 ).Two groups also showcd no significant difference for Cho/Cr in bilateral frontal lobe and hippocampus (P ＞ 0.05 ).Conclusion There is significant difference of manifestation of 1H-MRS between male patients with mania and normal controls,which reflects neuronal dysfunction in the prefrontal lobes and hippocampus.

ObjectiveTo examine biochemical characteristics of the frontal lobe and hippocampus in unaffected parentsof schizophreniaprohandsusingprotonmagneticresonancespectroscopy(1H-MRS).Method 19 unaffected fathers of schizophrenia probands with matched 19 male healthy control subjects and 24 unaffected mothers of schizophrenia probands with matched 24 female healthy control subjects were included in the study.1 H-MRS was performed in two sides of the hippocampus and frontal lobes regions.The ratios of N-Acetylaspartate ( NAA ),choline (Cho) to creatine (Cr) were measured.One-sample T test and paired-samples t test were used for statistic process.ResultsUnaffected mothers of schizophrenia probands had a higher Cho/Cr ratio ( left ( 1.10 ± 0.13,right ( 1.08 ± 0.12 ) ) in the frontal white matter compared with matched female health control subjects(left( 1.03 ± 0.10),right( 1.02 ± 0.09 )).The NAA/Cr ratio was significantly reduced in the left frontal white matter of female health control subjects compared to right( 1.64 ± 0.12 vs 1.74 ± 0.13 ),but this difference was not observed in unaffected mothers of schizophrenia probands.There were no significant differences in metabolites for frontal lobe and hippocampus regions between unaffected fathers of schizophrenia probands and male healthy control subjects groups( all P＞0.05 ).ConclusionThe results implicate that the metabolic abnormalities and disappeared asymmetry of NAA/Cr might exist in the frontal white matter among unaffected mothers of schizophrenia probands.

Objective To detect the patterns of cognitive impairment between patients with paranoid schizophrenia and patients with bipolar mania by using the Cambridge Neuropsychological Test Automated Battery (CANTAB) ,and to explore research clues for finding of cognitive endophenotype in patients with paranoid schizophrenia or bipolar mania. Methods Six CANTAB subtests and the seven subtests of the Wechsler Abbreviated Scale of Intelligence (WAIS short form) were administered to 35 patients with paranoid schizophrenia and 33 patients with bipolar mania who were drug naive experiencing an acute episode, as well as 30 healthy controls. Results Patients with paranoid schizophrenia and bipolar mania demonstrated impairments in 13 of the 15 cognitive indicators in CANTAB. After controlling IQ, both patient groups remained as significantly different from normal controls in terms of search strategy(36. 8 ±3.56,37.24 ±4. 21,30. 33 ±6.24) ,between-search errors(40. 86 ± 19.97,40.24 ± 18.92,15.4 ±17.22) on the SWM test,the proportion of hits(0.54 ±0. 18,0.56 ±0.15,0.78 ± 0.17) on the RVIP test,total errors(45.26 ±36.36,46.61 ±33.32,14 ± 11.7) and EDS errors (12.43 ±9.96, 13.18 ±8.98,4.97 ±6.09)on the IED test. Between search error in the SWM test was positively correlation with YMRS scores ( r=0.38, P=0.039) in bipolar patients. Conclusion Both patient groups demonstrated a comparable profile of cognitive impairments during active periods of their condition. The cognitive impairment index may be a discreet cognitive endophenotype overlapping the disorders.
