Brucellosis is one of the most widespread zoonoses globally, which poses serious threats to both global public health and development of animal husbandry. Conventional brucellosis control measures suffer problems of surveillance coordination, regional joint prevention, and policy implementation, which are insufficient to address the challenges of ecological risks and crosshost transmission. The One Health approach allocates interdisciplinary and intersectoral collaborations to achieve systemic health of humans, animals, and environments, which provides new insights into brucellosis control programmes. This review describes the pathogenic biological characteristics, global epidemiological landscape, and transmission ecology of brucellosis, evaluates the main limitations of current control strategies, summarizes the experiences from successful One Health practices across countries at different stages of development, and proposes the brucellosis control strategy based on the One Health concept with adaptations to the current epidemiology of brucellosis in China, so as to provide the theoretical evidence and practical framework for the national brucellosis control programmes in China, thereby facilitating the effective control and the ultimate elimination of brucellosis.

OBJECTIVE: To explore the mechanism of action of asperosaponin VI (AVI) in the treatment of rheumatoid arthritis (RA) and validate it in ex vivo experiments using network pharmacology and molecular docking methods. METHODS: The predicted targets of AVI were obtained from PharmMaper, UniProt and SwissTarget Prediction platforms, the disease targets were collected from Online Mendelian Inheritance in Man, Therapeutic Target Database and GeneCards databases, the intersection targets of AVI and RA were obtained from Venny 2.1.0, and the protein-protein interaction (PPI) network was obtained from STRING database, which was analyzed by Cytoscape software and screened to obtain the core targets. Cytoscape software was used to analyze PPI network and screen the core targets. Based on the Database for Annotation, Visualization and Integrated Discovery database, Gene Ontology functional and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis were performed, and Cytoscape software was used to construct the "Disease-Pathway-Target-Drug" network, which was finally verified by molecular docking and animal experiments. RESULTS: Network pharmacological studies showed that AVI was able to modulate 289 targets, with 102 targets for the potential treatment of RA, with the core pathway being the AKT/PI3K signaling pathway, and the core targets being the epidermal growth factor receptor (EGFR) and matrix metalloproteinase 9 (MMP9). Molecular docking results showed that AVI could produce strong binding with both of the 2 core targets. In vitro cellular experiments showed that AVI reduced nitric oxide, prostaglandin E₂, tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), and IL-1 β levels (P<0.05) and inhibited cyclooxygenase-2, nitric oxide synthase, EGFR, MMP9, phosphorylated phosphoinositide 3-kinase (p-PI3K), and phosphorylated serine-threonine kinase (p-AKT) proteins (P<0.05). The results of in vivo studies showed that AVI improved RA score and foot swelling thickness and decreased TNF-α, IL-6, p-PI3K and p-AKT levels in RA rats (P<0.05). CONCLUSION AVI exerts anti-inflammatory and anti-RA effects which might be related to the EGFR/MMP9/AKT/PI3K pathway.

Vertebral refracture following percutaneous vertebral augmentation (PVA) is commonly seen in elderly patients with osteoporotic thoracolumbar compression fractures (OTLCF). It can lead to recurrent pain, loss of vertebral height, progression of kyphosis, and even neurological dysfunction, significantly impairing patients′ quality of life. Current diagnosis and treatment face multiple challenges, including high misdiagnosis rate, difficulty in choosing between surgical and non-surgical treatment options, lack of standardized surgical protocols, interference from intralesional bone cement during procedures, inadequate stability of internal fixation in osteoporotic bone, and suboptimal compliance of anti-osteoporotic therapy. Establishing a standardized diagnostic and therapeutic framework is urgently needed. To standardize the management process and improve outcomes for vertebral refractures after PVA in elderly OTLCF patients, Spinal Trauma Group of the Orthopedic Branch of Chinese Medical Doctor Association organized experts in the field to develop Guideline for the diagnosis and treatment of vertebral refracture after percutaneous vertebral augmentation in elderly patients with osteoporotic thoracolumbar compression fractures ( version 2025), based on current literature and clinical experience, and adhering to principles of scientific rigor and clinical applicability. A total of 11 recommendations were proposed, encompassing diagnosis, treatment, and rehabilitation of vertebral refracture after PVA in elderly patients with OTLCF, aiming to provide a foundation for a standardized management.

Objective To investigate the clinical characteristics of asthma patients with deficiency of various viscera through the analysis of mitochondrial dysfunction and related influencing factors,and to explore the DDAH1/L-Arg/ADMA pathway as well as the trend of changes in the mitochondrial function and oxygen metabolism of the asthma patients through the analysis.Methods A total of 122 patients with acute exacerbation of bronchial asthma who met the inclusion criteria were selected,and their clinical data were collected.The patients were divided into 3 groups based on the criteria of visceral deficiency syndrome differentiation,namely lung qi deficiency group(47 cases),lung-spleen qi deficiency group(39 cases),and lung-spleen-kidney deficiency group(36 cases).Meanwhile,the normal control group including 44 cases was set up.For the asthma patients with visceral deficiency,an observation was conducted in the lung function indicators of forced expiratory volume in the first second(FEV1),the ratio of FEV1 to forced vital capacity(FEV1/FVC)and peak expiratory flow(PEF)as well as the severity of the disease.Moreover,venous blood was sampled from the patients for the detection of L-arginine(L-Arg)and asymmetric dimethylarginine(ADMA)levels with high-performance liquid chromatography coupled with mass spectrometry(HPLC-MS/MS),and for the detection of arginine metabolism related indicators of protein arginine methyltransferase 1(PRMT1)and dimethylarginine dimethylammonium hydrolysate 1(DDAH1)as well as the oxidative damage parameters of reactive oxygen species(ROS),thiobarbituric acid reactive substance(TBARS),8-iso-prostaglandins(8-iso),lipid peroxide(LPO),and malondialdehyde(MDA)with enzyme-linked immunosorbent assay(ELISA).The platelet mitochondria were extracted from asthma patients and normal controls,and then the mitochondrial membrane potential(MMP),adenosine triphosphate(ATP),and activities of cytochrome C oxidase(COX)in the platelet were determined by JC-1 flow cytometric assay in order to assess the mitochondrial function.The changes in the mitochondrial function and their influence on the mitochondrial function of asthma patients with deficiency of various viscera were analyzed and then compared with those of the normal control group.Results(1)There were statistically significant differences in the age and lung function(FEV1,FEV1/FVC,PEF)among asthma patients with deficiency of various viscera(P＜0.01):the age of the lung-spleen-kidney deficiency group was significantly older than that of the lung qi deficiency group and the lung-spleen qi deficiency group(P＜0.05),and the lung function(FEV1,FEV1/FVC,PEF)showed a significant downward trend with the aggravation of viscera deficiency(P＜0.05).(2)There was a statistically significant difference in the illness grading of patients with deficiency of various viscera(P＜0.01).In the lung qi deficiency group,the illness status was predominated by intermittent state of asthma(grade 1),accounting for 65.96%,and then followed by mild asthma(grade 2),accounting for 25.53%.In the lung-spleen qi deficiency group,the illness status was predominated by moderate asthma(grade 3),accounting for 41.03%,and then followed by intermittent state of asthma(grade 1),accounting for 30.77%.In the lung-spleen-kidney deficiency group,the illness status was predominated by severe asthma(grade 4),accounting for 52.78%,and then followed by moderate asthma(grade 3),accounting for 33.33%.It is indicated that with the aggravation of viscera deficiency,the severity of asthma tended to be aggravated.(3)There were significant differences in plasma 8-iso,ROS,LPO and MDA levels between asthma patients with deficiency of various viscera and normal control group(P＜0.05).The plasma 8-iso and LPO levels of the asthma patients with deficiency of various viscera and the plasma MDA and ROS levels of asthma patients with lung-spleen qi deficiency and lung-spleen-kidney deficiency were significantly higher than those in normal control group(P＜0.05),and the plasma ROS level of asthma patients with lung-spleen qi deficiency and lung-spleen-kidney deficiency was significantly higher than that in asthma patients with lung qi deficiency(P＜0.05).The plasma TBARS level of asthma patients with deficiency of various viscera tended to be higher than that of normal control group,but the difference was not statistically significant(P＞0.05).It is indicated that reactive oxygen species and peroxide lipids accumulated in the body of asthma patients with deficiency of various viscera,and their levels increased with the aggravation of visceral deficiency.(4)The levels of MMP,ATP and COX in asthma patients with deficiency of various viscera were significantly lower than those in normal control group(P＜0.05),and the activity of COX decreased with the aggravation of visceral deficiency.(5)The levels of plasma L-Arg,L-Arg/ADMA and DDAH1 in asthma patients with deficiency of various viscera were significantly lower than those in normal control group(P＜0.05),and their levels decreased gradually with the aggravation of visceral deficiency.There was no significant difference in the plasma ADMA and PRMT1 levels between asthma patients with deficiency of various viscera and normal control group(P＞0.05).Conclusion It is indicated that the visceral deficiency in asthma patients is consistent with the progression of illness status,oxygen metabolism and its influencing factors,and the degree of oxidative damage.It is suggested that the progression of illness status can be judged by visceral deficiency in traditional Chinese medicine according to the parameters of body metabolism.
