Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is an immune-mediated demyelinating peripheral neuropathy characterized by symmetric limb weakness, sensory disturbances, and diminished tendon reflexes. Its pathogenesis involves the interplay of T cells, B cells, and the complement system. Current first-line therapies including intravenous immunoglobulin, corticosteroids and plasma exchange exhibit limited efficacy, with approximately 30% of patients experiencing relapse or poor treatment response. In recent years, novel immunomodulatory therapies including anti-CD20 monoclonal antibodies, neonatal Fc receptor inhibitors, complement inhibitors, Bruton tyrosine kinase inhibitors, autologous hematopoietic stem cell transplantation, and chimeric antigen receptor T-cell therapy, have emerged as promising options for refractory CIDP, ushering in a new era of immunomodulatory treatment.

Purpose: Gastric cancer (GC) is among the deadliest malignancies and the third leading cause of cancer-related deaths worldwide. Galectin-1 (Gal-1) is a primary protein secreted by cancer-associated fibroblasts (CAFs); however, its role and mechanisms of action of Gal-1 in GC remain unclear. In this study, we stimulated GC cells with exogenous human recombinant galectin-1 protein (rhGal-1) to investigate its effects on the proliferation, migration, and resistance to cisplatin. Materials and Methods: We used simulated rhGal-1 protein as a paracrine factor produced by CAFs to induce GC cells and investigated its promotional effects and mechanisms in GC progression and cisplatin resistance. Immunohistochemical (IHC) assay confirmed that Gal-1 expression was associated with clinicopathological parameters and correlated with the expression of neuropilin-1 (NRP-1), c-JUN, and Wee1. Results: Our study reveals Gal-1 expression was significantly associated with poor outcomes.Gal-1 boosts the proliferation and metastasis of GC cells by activating the NRP-1/C-JUN/ Wee1 pathway. Gal-1 notably increases GC cell resistance to cisplatin The NRP-1 inhibitor, EG00229, effectively counteracts these effects. Conclusions These findings revealed a potential mechanism by which Gal-1 promotes GC growth and contributes to chemoresistance, offering new therapeutic targets for the treatment of GC.

Gamma band oscillation (GBO) and sensory gating (SG) are associated with many cognitive functions. Ketamine induces deficits of GBO and SG in the prefrontal cortex (PFC). However, the time-courses of the effects of different doses of ketamine on GBO power and SG are poorly understood. Studies have indicated that GBO power and SG have a common substrate for their generation and abnormalities. In this study, we found that (1) ketamine administration increased GBO power in the PFC in rats differently in the low- and high-dose groups; (2) auditory SG was significantly lower than baseline in the 30 mg/kg and 60 mg/kg groups, but not in the 15 mg/kg and 120 mg/kg groups; and (3) changes in SG and basal GBO power were significantly correlated in awake rats. These results indicate a relationship between mechanisms underlying auditory SG and GBO power.

OBJECTIVETo discuss the surgical strategies and analyze the clinical outcomes of multiple intracranial aneurysms (MIA).

METHODSThe clinical data of 49 MIA patients surgically treated between January 2009 and December 2013 was analyzed retrospectively. Among the 49 patients, 12 patients were male and 37 were female, mean age (49 ± 11) years. Thirty-five patients had ruptured aneurysms, and 14 had unruptured aneurysms. Treatment strategies included one-stage operation (MIA were treated in one-stage with an unilateral approach), two-stage treatment (MIA were treated stage by stage) and partial treatment (only ruptured aneurysm was treated). Postoperative CT angiograms (CTA) or digital subtraction angiograms (DSA) were reviewed and the Glasgow Outcome Scale (GOS) scores were evaluated during follow-up period.

RESULTSThirty-two patients (65.3%) underwent one-stage operation, 9 patients (18.4%) underwent two-stage treatment, and 8 patients (16.3%) underwent partial treatment. Forty-seven patients were followed up 4-49 months, mean (22 ± 7) months. Postoperative CTA or DSA showed no aneurysm recurrence. According to the GOS scores, 41 patients (83.7%) with good outcomes (GOS 4, 5), 6 patients (12.2%) were disabled (GOS 2, 3) and 2 patients (4.1%) were dead (GOS 1).

CONCLUSIONSelecting the right patients for surgery and making personalized surgical strategies based on the characteristics of patients and aneurysms could improve the surgical outcomes of MIA.
