Objective Based on the US Food and Drug Administration(FDA)adverse event Reporting System(FAERS),to explore the signal of adverse events of basiliximab in solid organ transplantation,and to provide reference for its clinical safety.Methods The adverse drug event(ADE)signals of basiliximab in solid organ transplantation from the first quarter of 2004 to the second quarter of 2024 were retrospectively analyzed in the FAERS database of the FDA.The reporting odds ratio(ROR)method and Bayesian confidence propagation neural network(BCPNN)method were used for signal mining.Results A total of 1,581 ADE reports related to the use of basiliximab were obtained,involving 27 system/organ classifications.A total of 460 ADE signals were identified.The top 5 PT signals in terms of report frequency were mainly elevated serum creatinine,fever,cytomegalovirus infection,decreased hemoglobin,and decreased lymphocyte count.The top 5 PT signals in terms of signal intensity were mainly cytomegalovirus infection,elevated serum creatinine,decreased lymphocyte count,increased neutrophil count,and thrombotic microangiopathy.New ADE signals identified included decreased lymphocyte count,thrombotic microangiopathy,eye organ diseases,Kaposi's sarcoma,elevated blood lactate dehydrogenase,elevated transaminases,and shock.Conclusion Data mining using FAERS database is helpful to find new ADE signals of basiliximab in solid organ transplantation.Clinicians should focus on new severe ADE signals such as coagulation function,ocular organ diseases,elevated transaminase,shock and so on.

Ankylosing spondylitis(AS)is a chronic autoimmune disease characterized by inflammatory involvement of the axial skeleton and pathological bone formation.The T helper 17 cell(Th17 cell)subset of lym-phocytes plays a central role in mediating the inflammatory processes associated with AS.This review summarizes recent advances in the regulation of Th17 cell differentiation in AS,with a focus on the complex mechanisms governed by cytokine microenvironments,transcription factor networks,and metabolic and epigenetic regulatory pathways.Key regulatory components discussed include the IL-23/STAT3 signaling axis,the CCL20/CCR6 chemo-tactic axis,and the master transcription factor RORγt.Additionally,this review critically evaluates emerging thera-peutic strategies targeting metabolic reprogramming(e.g.,PKM2),epigenetic regulators(e.g.,JMJD3,EZH2),engineered exosome delivery systems,and modulators of metabolic enzymes.By analyzing the limitations of current treatment approaches,the review proposes future research directions emphasizing multi-target therapeutic strategies and highlights the importance of personalized medicine in achieving precise and effective treatment for AS.These developments reveal promising new avenues for modulating Th17-mediated immunity,offering transformative poten-tial for the clinical management of AS.

Objective To investigate the effect of platelet lysate on mitochondrial function of astrocytes after spinal cord injury.Methods Astrocytoma cells SVGp12 were incubated with different concentrations of H2O2 (100 μmol/L,400 μmol/L,1000 μmol/L,2000 μmol/L),and the OD value was determined by CCK-8 assay. The H2O2 concentration with a cell inhibition rate of about 50％ was selected for follow-up experiments. The cells were incubated with different concentrations of platelet lysate (the volume ratios of platelet lysate to culture medium were 1∶10,1∶40,1∶80,1∶160 and 1∶320) for 24 hours,and the OD value was determined,thereby selecting the optimal concentration of platelet lysate based on the cell survival rate. SVGp12 cells were divided into the normal group (cultured normally without special treat-ment),the model group (incubated with 1000 μmol/L of H2O2 for 3 hours),and the treatment group (incubated with 1000 μmol/L of H2O2 for 3 hours and then treated with platelet lysate at a volume ratio of 1∶80). The mitochondrial function was evaluated by mitochondrial activity staining,mitochondrial membrane potential detection,and mitochondrial permeability transition pore detection. Results After incubating cells with 1000 μmol/L of H2O2 for 3 hours,the cell inhibition rate was 48％,and the OD value decreased significantly (P<0.01),confirming the successful establishment of a model of astrocytes with spinal cord injury. After treated with different concentrations of platelet lysate,the OD values and cell survival rate of the cells were higher than those in the model group (P<0.05). The concentration of platelet lysate (volume ratio of 1∶80) with cell viability of 20％ was selected for follow-up experiments. Platelet lysate could improve the morphology of injured astrocytes. The mitochondrial activity of the treatment group was significantly higher than that of the model group,and the mitochondrial activity of the model group was significantly lower than that of the normal group,with statistically significant differences (P<0.05). The mitochondrial membrane potential in the model group was lower than that in the normal group,and the mitochondrial membrane potential in the treatment group was higher than that in the model group,with statistically significant differences (P<0.01). The mitochondrial permeability in the model group was greater than that in the normal group,and the mitochondrial permeability in the treatment group was smaller than that in the model group,with statistically significant differences (P<0.01).Conclusion Platelet lysate can improve the survival rate of astrocytes after spinal cord injury,enhance the mitochondrial activity of cells,and improve the mitochondrial membrane potential and mitochondrial permeability transition pore opening.

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.
