Purpose To investigate interhemispheric homotopic functional connectivity in patients with neuropsychological systemic lupus erythematosus(NPSLE)during resting state and its relationship with clinical indicators and neuropsychological scales.Materials and Methods This prospective study enrolled 35 patients with NPSLE and 31 healthy controls(control group)from Taizhou People's Hospital Affiliated to Nanjing Medical University(June 2020 to March 2023).All participants underwent resting state functional MRI and completed neuropsychological assessments including mini-mental state examination,Montreal cognitive assessment,hospital anxiety and depression scale,fatigue scale for motor and cognitive functions,along with laboratory tests(C3,C4,IgA,IgM,IgG).Image preprocessing and voxel-mirrored homotopic connectivity(VMHC)calculations were performed using DPABI V7.0 on Matlab R2013b.Between-group differences in VMHC values were compared,and correlations between VMHC values in significant regions and neuropsychological/clinical data were analyzed.Results The NPSLE group demonstrated significantly lower mini-mental state examination and Montreal cognitive assessment scores compared with those in control group(t=-6.297,-7.001,both P=0.001).Patients with NPSLE exhibited significantly decreased VMHC values in bilateral parahippocampal gyri,precentral gyri,middle frontal gyri,and medial/paracingulate gyri compared with those in control group(family-wise error corrected,voxel-level P<0.001,cluster-level P<0.05).In the NPSLE group,VMHC values in precentral gyri showed positive correlation with IgA levels(r=0.351,P=0.039),while VMHC values in medial/paracingulate gyri positively correlated with IgA(r=0.345,P=0.043)and negatively with C4(r=-0.368,P=0.030).Conclusion Patients with NPSLE demonstrate abnormal interhemispheric homotopic functional connectivity,and the correlation between imaging metrics and clinical data in differential brain regions may facilitate early diagnosis of NPSLE while providing novel insights into the neuropathological mechanisms of cerebral injury.

Objective To investigate the post-intervention experiences in elderly stroke patients who received the group-based acceptance and commitment therapy(ACT)and to provide a reference to improve the group-based ACT intervention strategies for the patients.Methods With the descriptive phenomenological research,the semi-structured in-depth interviews were conducted with 15 elderly stroke patients who had received the group-based ACT intervention for 6 months in a Tier-IIIA hospital in Hunan Province between May and July 2023.The data acquired from the interviews were analysed using the Colaizzi method.Results The experiences in elderly stroke patients with the group-based ACT intervention were categorised into three main themes and ten sub-themes:(1)The impact of intervention on the psychology and spirit(change cognition and accept oneself;enhance awareness and reflect on oneself;clarify values and adapt to oneself;disengage from suffering and achieve dissociation;understand suffering and discover a sense of meaning in life);(2)Behavioural changes brought by the intervention(change approaches to improve health;engage in rehabilitation exercises and build confidence;enhance social interactions and integrate into life);(3)Suggestions for the intervention program(tailor to the physiological characteristics of the elderly;adapt to the psychological characteristics of the elderly).Conclusion The group-based ACT intervention has a beneficial effect on the psychological,spiritual and behavioural changes in the elderly stroke patients.The intervention programs should be improved according to the physical and mental characteristics therefore to improve the mental health of elderly stroke patients.
