Objective To explore the effects of mental fatigue on attention maintenance function by electroencephalogram(EEG)signal characteristics and cortical source analysis.Methods A total of 25 healthy males were recruited as subjects and contingent negative variation(CNV)auditory paradigm was used to assess the differences in EEG characteristics before and after mental fatigue,with the average amplitude of CNV at different processing stages as the analysis indices.Then,the 3-dimensional distribution of cortical current density changes of CNV after mental fatigue were calculated by standardized low-resolution electromagnetic tomography analysis(sLORETA).Results The reaction time of the CNV signal remained unchanged following mental fatigue(P＞0.05),while the lapse rate exhibited a significant increase(P＜0.05).Besides,mental fatigue was related to a notable decrease in the amplitude of CNV early components(500-1 000 ms after warning stimulus)at the central and central parietal electrodes,and a significant reduction in the amplitude of CNV late components(2 550-3 050 ms after warning stimulus)at the prefrontal,frontal,central,and central parietal electrodes(all P＜0.05).The results of sLORETA source analysis showed that the brain activity in the left posterior insular cortex decreased after mental fatigue during the late component of CNV(P＜0.05).Conclusion The decreased activation of the posterior insula,which plays a crucial role in sensorimotor information integration,could potentially serve as a neural mechanism for the reduction of CNV amplitude and the impairment of attention maintenance function following mental fatigue.

Primary blast lung injury is an acute lung injury caused by the direct impact of explosive shock wave acting on the lung;the serious case can develop acute respiratory distress syndrome,which is one of the leading causes of mortality in blast injury personnel.The pathophysiological characteristics of primary lung blast injury are relatively clear:rupture of the alveolar capillaries and subsequent intrapulmonary haemorrhage and edema,accompanied by oxidative stress,apoptosis,inflammatory reaction and other physiological processes.However,the molecular mechanism needs to be further studied.This paper focuses on the research progress of phosphatidylinositol 3-kinase/protein kinase,nuclear factor κB,mitogen-activated protein kinase and other signaling pathways in the research of primary blast lung injury.

Objective To investigate the relationship between cerebral perfusion status,blood pressure variability,and prognosis in patients with moyamoya disease following cerebral revascularization.Methods A retrospective analysis was conducted on 108 patients who underwent their first combined cerebral revascularization between January 2019 and July 2022 at the Department of Neurosurgery,First Affiliated Hospital of Henan University,and Henan Provincial People's Hospital.Based on postoperative cerebral perfusion improvement,patients were categorized into a"good"group and a"general"group.Baseline characteristics,key imaging parameters,blood pressure variability,and symptom scores were compared and analyzed between the two groups.Results In this study,there were 55 cases in the good group and 53 cases in the general group.According to the comparative analysis of the postoperative indicators between the good group and the general group,Statistically significant differences were observed in symptom improvement[42(79.25%)vs.52(94.55%)],TIA[22(41.51%)vs.11(20.00%)],and cerebral infarction[6(11.32%)vs.0(0.00%)],mRS score and the Matsushima classification(P<0.05).However,there was no statistically significant difference in the BPV-related index between the two groups of patients before the operation(all P>0.05).When comparing nine blood pressure variability(BPV)-related indices including the mean of 24-hour,daytime,and nighttime systolic blood pressure,coefficient of variability(CV),and average real variability(ARV)between the two groups,no significant differences were observed in the BPV-related indices before surgery between the two groups(P>0.05).The differences in the BPV-related indices before and after surgery(postoperative index-preoperative index)between the two groups were statistically significant(P<0.05).Postoperative cerebral perfusion status was positively correlated with prognosis and negatively correlated with BPV.Conclusion Patients with good improvement in cerebral perfusion status after combined revascularization for moyamoya disease have less blood pressure variability and better prognosis.

T-cell inhibitory receptors(IR)are involved in the composing of co-inhibitory signaling pathways between T cells and immune cells,and transmit immunosuppressive signals to limit immune effects of T cells such as activation and proliferation.Ab-normal co-inhibitory signals may destroy the peripheral immune tolerance of the body,leading to hyperresponsiveness of various organ-specific autoimmunity.Rheumatoid arthritis(RA)is a complex systemic disease in which there is an immune disorder centered on T cells.In this process,the abnormal expression and distribution of T-cell IR are fully involved in the imbalance of T-cell subsets and pathological immune responses,affecting the development and progression of the disease.Targeting T-cell IR and its ligands and thus strengthening the co-inhibitory signaling pathway mediated by them has been studied for suppressing immune responses and maintain-ing immune tolerance,but their potential for clinical application in RA remains to be explored.In the present,we review the advances of T-cell IR involved in the immunopathology of RA,and discusses the therapeutic prospects of targeting these receptors.

To summarize the experience of Professor WANG Qingguo in diagnosing and treating wind-cold-dampness arthralgia based on the principle that "the nutrient-defense qi does not merge with wind-cold-dampness qi， so it did not result to arthralgia". By analyzing the relationship between nutrient-defense qi and wind-cold-dampness arthralgia， it is believed that the occurrence of wind-cold-dampness arthralgia is closely related to the movement of nutrient qi and defense qi， and the key to the treatment of this disease is to regulate nutrient qi and defense qi and remove the combination of nutrient-defense qi and wind-cold-dampness qi. The core pathogenesis of wind-cold-dampness arthralgia in the early stage is the initial combination of nutrient-defense qi and wind-cold-dampness qi， and the treatment should harmonize nutrient-defense qi and eliminate the pathogen and release pathogenesis， with Chaihu Guizhi Decoction （柴胡桂枝汤） as the main prescription； the core pathogenesis of the middle stage is nutrient-defense qi and wind-cold-dampness qi cemented together， and the treatment should harmonize and tonify nutrient qi and defense qi and separate the pathogen to alleviate disease， with self-prescribed Chuanteng Tongbi Decoction （穿藤通痹汤） as the main prescription； the core pathogenesis of the late stage is deficiency and stagnation of nutrient-defense qi， wind-cold-dampness qi still exist， and the treatment should tonify and free nutrient qi and defense qi to eliminate pathogen and arthralgia， with self-prescribed Chuanqing Haijia Decoction （穿青海甲汤） plus Duhuo Jisheng Decoction （独活寄生汤） as the main prescription.
