The neonatal Fc receptor(FcRn)prolongs the half-life of immunoglobulin G(IgG)and promotes its recycling by binding to and making it an important receptor for maintaining serum IgG homeostasis.However,the abnormal accumulation of pathogenic IgG is closely related to the occurrence of various neuroimmune diseases.FcRn antagonists can significantly reduce the level of pathogenic IgG by blocking the binding of FcRn to IgG,thereby effectively alleviating the clinical symptoms of related diseases.As an emerging targeted therapeutic drug,FcRn antagonists have shown their potential in treating IgG-mediated neuroimmune diseases.This article summarizes the mechanism of action,types and clinical research progress of FcRn antagonists with the aim of providing new ideas for the precise treatment of IgG-mediated neuroimmune diseases.Future research should focus on the long-term safety of drugs,expansion of indications and individualized treatment strategies to further enhance their clinical application value.

OBJECTIVE To systematically analyse the research status and hotspots of Jiegeng decoction from the perspective of bibliometrics,and to provide theoretical references for its clinical application and in-depth research.METHODS We searched the relevant literature in the databases of China Knowledge Network(CNKI),Wanfang and VIP up to March 2025,and used NoteExpress for de-duplication and screening,combined with Excel,CiteSpace,and VOSviewer to analyse the dimensions of trend of issuance,country/institution cooperation,author network,and keywords.The dimensions of publication trend,country/institution collaboration,author network and keywords were visualised and analysed by combining Excel,CiteSpace and VOSviewer.RESULTS A total of 597 Chi-nese articles were included.The number of variable publications was characterised by a four-stage evolution,with the core research in-stitutions focusing on TCM colleges and affiliated hospitals,and less cross-country collaboration.Literature focused on the effects of Jiegeng decoction on"cough","treatment"and"chronic pharyngitis".Emerging keywords indicated that"mechanism of action","therapeutic effect","medication pattern"and"antiviral"were emerging hot topics in recent years.CONCLUSION The study of Jiegeng decoction is shifting from single disease treatment to multi-target system regulation.In the future,it is necessary to strengthen the interdisciplinary integration,deepen the research on the immunomodulatory mechanism of Jiegeng decoction in respiratory viral in-fections,build the"chemical component-biological effect"related quality control system,deepen the combination of network pharma-cology and real-world research,and provide a new paradigm for the modernisation of classical prescriptions.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

OBJECTIVE To study the repair effect and mechanism of Zhixu burn ointment on deep second-degree burned model rats. METHODS The deep second-degree burned model was established with a temperature-controlled apparatus. The model rats were randomly divided into model group， Jingwanhong ointment group and Zhixu burn ointment high-dose， medium-dose and low-dose groups （specifications were 20 g core+20 mL wetting agent， 10 g core+20 mL wetting agent， 5 g core+20 mL wetting agent， respectively）. Another blank control group （only dehairing treatment， no modeling） was set up， with 10 rats in each group. The rats in each administration group were given corresponding drugs， the rats in the blank control group were not treated， and the rats in the model group were given normal saline once a day for 21 d. The healing of burn wounds and histomorphological changes of burned skin in each group of rats were observed， and the healing rate of wounds was calculated； the levels of vascular endothelial growth factor （VEGF）， interleukin-1β （IL-1β）， IL-6 and tumor necrosis factor-α（TNF-α） in the wound skin tissue of rats were detected by enzyme-linked immunosorbent assay； immunohistochemical method was used to detect the expression levels of VEGF and platelet endothelial cell adhesion molecule-1 （CD31） protein in burned skin tissue. RESULTS Compared with model group， the wound area of the rats in the Jingwanhong ointment and Zhixu burn ointment groups gradually decreased and healed significantly by day 21， and the wound healing rate was significantly higher （P＜0.05 or P＜0.01）； thicker new epidermal layer was seen in the skin tissue， and connective tissue and new blood vessels were significantly increased in the dermis； the expression levels of IL-1β， IL-6 and TNF-α were significantly decreased （P＜0.05 or P＜0.01）， and the expression levels of VEGF and CD31 protein were significantly increased （P＜0.05 or P＜0.01） in the burned skin tissue. CONCLUSIONS Zhixu burn ointment can repair the skin of deep second-degree burned model rats， and the mechanism may be related to reducing the inflammatory response of burn wound and promoting the angiogenesis.

Objective To investigate the clinical features and prognosis of antimyelin oligodendrocyte glycoprotein-IgG （MOG-IgG） associated disorders （MOGAD）.Methods Eight cases met the diagnostic criteria of MOGAD were reviewed，and the demographics，clinical manifestations，laboratory and imaging results，treatment and prognosis were analyzed. The Expanded Disability Status Scale （EDSS） and the modified Rankin Scale （mRS） were used to dynamically evaluate the neurological disability. Results The ratio of male to female in this 8-case series was 1∶1，the median onset age was 34 years old，and the median disease duration was 42 months. The most common initial symptom is optic neuritis （ON，50%），followed by meningitis and/or encephalitis （25%）. Recurrence occurs in 50% of cases，and the recurrence rate of patients with high serum MOG IgG titer （≥1∶32） is 60%. The white blood cells in the cerebrospinal fluid in cases with meningitis/encephalitis or longitudinally extensive myelitis is often>100×10-6/L，which is higher than other phenotypes. There are 6 cases （75%） of patients with different MRI abnormalities，including hypertensity on T-2/Flair image with enhancement at affected optic nerve and orbital tissue，asymptomatic diencephalon/thalamus lesions on T2 and contrasted image，and MRI findings mimic typical multiple sclerosis may also be present. Cases with myelitis can show short-segment eccentric lesions or long-segment central lesions on MRI. Cases with meningitis/encephalitis showed unilateral cortical high T-2/Flair lesions on cranial MRI with various enhancements. After medication and rehabilitation，the peak EDSS of this case series was 5±1.069，and 2.19±1.689 points at the last visit；mRS was 3.25±1.165 points at the peak and 1.25±1.035 points at the last visit. The difference was statistically significant.Conclusions MOGAD is a rare type of demyelinating disease in central nervous with various manifestations，which is highly treatable. Fully understanding of the clinical characteristics，making a early diagnosis through comprehensive tests，and initiating immunization and rehabilitation treatment in time，will contribute to better prognosis for patients.
