Objective:To induce an experimental autoimmune encephalomyelitis(EAE)model by MOG-specific TCR trans-genic mice(2D2TCR transgenic mice),and to investigate effect of exogenous ERMAP on T cells in spleen of MOG35-55-induced 2D2TCR transgenic mice.Methods:EAE models were established in two groups of 2D2TCR transgenic mice(Control-Ig treatment for control group and ERMAP-Ig fusion protein treatment for experimental group),with 9 mice per group.Severity of spinal cord injury of MOG35-55-induced EAE in mice was assessed based on daily clinical scores(DAI),HE and LFB staining results;autoreactive T cells(CD4+Vα3.2+Vβ11+),T cell proliferation activation indicators CD69(CD4+Vα3.2+Vβ11+CD69+)and Ki67(CD4+Vα3.2+Vβ11+Ki67+),Treg(CD4+Vα3.2+Vβ11+CD25+Foxp3+)and Th17 cells(CD4+Vα3.2+Vβ11+IL-17A+)in spleen were detected by flow cytome-try;IL-17A,IL-6,IFN-γ and TGF-β expressions in spinal cord tissues were detected by qRT-PCR.Results:In MOG35-55-induced 2D2TCR transgenic mouse EAE model,ERMAP-Ig fusion protein treatment group showed milder inflammatory infiltration and demye-lination in spinal cord,decreased proportion of autoreactive T cells,decreased proportion of activated and proliferating T cells,increased proportion of Treg,inhibition of Th17 cell differentiation,less inflammatory cell aggregation and cytokine production,and increased expression of anti-inflammatory factors in spinal cord.Conclusion:ERMAP may be involved in development of EAE in 2D2TCR transgenic mice by inhibiting T cell proliferative activation and promoting Treg cell production.

Objective:To investigate the treatment and management of patients with endemic fluorosis (referred to as fluorosis) in Ankang City, Shaanxi Province, and to provide a scientific basis for adjusting and optimizing treatment and management strategies for fluorosis patients.Methods:A retrospective analysis was conducted on patient information collected from county-level disease prevention and control centers in Ankang City from 2019 to 2023. Data included demographic information, clinical treatment, chronic disease management, treatment records, work reports, and summaries. The study aimed to learn about the treatment willingness, methods, and effects of patients with fluorosis, and to evaluate the disease management situation of patients with fluorosis.Results:From 2019 to 2023, the proportion of fluorosis patients who were willing to receive treatment in Ankang City had increased from 76.80% (1 089/1 418) in 2019 to 100% (1 408/1 408) in 2023, showing an upward trend year by year (χ 2trend = 971.15, P < 0.001). A total of 6 876 patients received treatment, with a treatment rate of 100%. The majority of patients received drug treatment (99.64%, 6 851/6 876), with an effective rate of 94.90% (6 525/6 876). The effective rate of treatment for patients with fluorosis had increased from 88.71% (966/1 418) in 2019 to 94.67% (1 333/1 408) in 2023, showing an upward trend (χ 2trend = 1 002.92, P < 0.001). The adverse reaction rate of drug treatment was 0.36% (25/6 876). The combination of oral medication and local treatment had the highest effective rate (97.62%, 3 566/3 653). The management rate and contracted service rate of fluorosis patients were 100% each year, and the standardized management rate was above 99%. Conclusions:Fluorosis patients in Ankang City have a high willingness to receive treatment, with good treatment outcomes. The contracted services and management of patients are well implemented. In the future, continuous efforts should be made to improve the prevention, management, and health education of fluorosis patients.

Aim To explore the therapeutic effect and mechanism of Qingjie Huagong decoction in modulating PI3K/AKT/NF-κB signaling pathway in inflammatory response of acute pancreatitis(AP)mice.Methods Twenty-four mice were randomly divided into Blank group,Model group,Ustekin group,and Qingjie Hua-gong decoction group,with six mice in each group.The AP model was prepared by using rain frogin.Serum α-AMS,PNLP,IL-1β,IL-6,IL-8,IL-18,and TNF-α lev-els were detected by ELISA;the pancreatic pathology was detected by HE staining;the expressions of PI3K,AKT,and NF-κB-related proteins and mRNAs were de-tected by immunohistochemistry,Western blot,and RT-qPCR.Results Compared with the blank group,the model group showed obvious pathological damage to the pancreas,with significantly higher serum α-AMS,PN-LP,IL-1β,IL-6,IL-8,IL-18,and TNF-α levels(P＜0.01),and significantly higher levels of PI3K,AKT,and NF-κB-related proteins and mRNA expression(P＜0.01).Compared with the model group,both the Qingjie Huagong decoction group and the ustekin group improved the histopathological changes in the pancreas of AP mice,decreased the serum α-AMS,PNLP,IL-1β,IL-6,IL-8,IL-18,and TNF-α levels,and down-reg-ulated the expression levels of pancreatic PI3K,AKT,NF-κB-related proteins and mRNA(P＜0.05 or P＜0.01).Conclusion Qingjie Huagong decoction may inhibit the inflammatory response and protect pancreat-ic tissues by regulating the expression of PI3K/AKT/NF-κB signaling pathway.

Objective To observe the clinical efficacy of traditional Chinese medicine(TCM)sequential therapy in treating patients with psoriasis vulgaris in Shenzhen,and to explore the syndrome differentiation and treatment for the patients with psoriasis vulgaris in Shenzhen region.Methods From January 2019 to February 2024,70 cases of psoriasis vulgaris admitted to Shenzhen Bao'an Traditional Chinese Medicine Hospital Affiliated to Guangzhou University of Chinese Medicine(Shenzhen Bao'an Traditional Chinese Medicine Hospital Group)were retrospectively analyzed.The patients were divided into the observation group(39 cases)and the control group(31 cases)according to the treatment plans.In the control group,only topical application of Calcipotriol Ointment was given throughout the treatment,while in the observation group the patients were treated with TCM sequential therapy according to the illness stage on the basis of treatment for the control group,i.e.,internal administration of modified Shuiniujiao Huanglian Decoction was given in the acute stage and modified Sijunzi Shuiniujiao Decoction was given in the remission stage.Both groups were treated for 3 months.Before and after the treatment,the changes of Psoriasis Area and Severity Index(PASI)scores,Dermatology Life Quality Index(DLQI)scores and TCM syndrome scores in the two groups were observed.After treatment,the clinical efficacy and drug safety of the two groups were evaluated.Results(1)After 3 months of treatment,the total effective rate of the observation group was 89.74%(35/39),and that of the control group was 74.19%(23/31).The intergroup comparison(tested by chi-square test)showed that the efficacy of the observation group was significantly superior to that of the control group(P＜0.05).(2)After treatment,the PASI scores for evaluating the severity of skin lesions in the two groups were significantly decreased compared with those before treatment(P＜0.05),and the decrease in the observation group was significantly superior to that in the control group(P＜0.05).(3)After treatment,the DLQI scores for evaluating the quality of life in the two groups were significantly decreased compared with those before treatment(P＜0.05),and the decrease in the observation group was significantly superior to that in the control group(P＜0.05).(4)After treatment,the scores of TCM syndromes such as erythema,itching,vexation and dry mouth in the two groups were significantly decreased compared with those before treatment(P＜0.05),and the decrease in the observation group was significantly superior to that in the control group(P＜0.05).(5)During the treatment period,no obvious adverse reactions occurred in the two groups of patients,with high safety.Conclusion On the basis of conventional western medicine treatment,application of TCM sequential therapy exerts certain clinical efficacy in treating patients with psoriasis vulgaris in Shenzhen region,and the combined therapy is effective on controlling the patients'illness conditions,significantly alleviating the symptoms and improving the quality of life of the patients.

Acute Gelsemium poisoning is a systemic disease primarily affecting the central nervous system and respiratory symptoms caused by the ingestion of a substantial amount of Gelsemium within a short period. It manifests as sudden onset and rapid progression, primarily caused by accidental ingestion due to misidentification, and posing significant health risks. The compilation of the Technical Plan for Emergency Health Response to Acute Gelsemium Poisoning describes in detail the specialized practice and technical requirements in the process of handling acute Gelsemium poisoning, including accident investigation and management, laboratory testing and identification, in-hospital treatment, and health monitoring. The guidelines clarify key procedures and requirements such as personal protection, investigation elements, etiology determination, medical rescue, and health education. The key to acute Gelsemium poisoning investigation lies in promptly identifying the toxin through exposure history, clinical manifestations, and sample testing. Because there is no specific antidote for Gelsemium poisoning, immediate removal from exposure, rapid elimination of the toxin, and respiratory monitoring are critical on-site rescue measures. Visual identification of food or herbal materials, followed by laboratory testing to determine Gelsemium alkaloids in samples is a rapid effective screening method. These guidelines offer a scientific, objective, and practical framework to support effective emergency responses to acute Gelsemium poisoning incidences.

OBJECTIVES: To study the clinical characteristics of pediatric Behçet syndrome (BS). METHODS: A retrospective review was conducted on the medical records of children hospitalized in the Department of Pediatrics at the Second Hospital of Hebei Medical University between December 2014 and December 2024 who met diagnostic criteria for BS. RESULTS: Among 45 children with BS, 26 (58%) were male. Oral aphthous ulcers were the most common manifestation (43/45, 96%), followed by genital ulcers (23/45, 51%) and gastrointestinal involvement (18/45, 40%). Genital ulcers were more frequent in girls, whereas ocular involvement was more common in boys (P<0.05). The pathergy test was positive in 10 (22%), and HLA-B51 was positive in 13 (29%). Fecal calprotectin (FC) was elevated in 16 (36%); gastrointestinal involvement was more frequent in children with elevated FC than in those with normal FC (P<0.05). According to the respective criteria, 17 (38%) patients met the International Study Group criteria (1990), 33 (73%) met the International Criteria for Behçet Disease (2014), and 13 (29%) met the Pediatric Behçet Disease criteria (2015). CONCLUSIONS Pediatric BS shows marked clinical heterogeneity. HLA-B51 is associated with disease susceptibility.

OBJECTIVE: To explore the efficacy and apoptosis of allogeneic hematopoietic stem cell transplantation (allo-HSCT) in the treatment of acute myeloid leukemia (AML) with ASXL1 mutation. METHODS: The clinical data of 80 AML patients with ASXL1 mutation treated in our hospital from January 2019 to December 2021 were retrospectively analyzed. The clinical characteristics of the patients were summarized, and the therapeutic effect and prognostic factors of allo-HSCT for the patients were analyzed. RESULTS: Among the 80 patients, 38 were males and 42 were females, and the median age was 39(14-65) years. There were 17 patients in low-risk group, 25 patients in medium-risk group and 38 patients in high-risk group. ASXL1 mutation co-occurred with many other gene mutations, and the frequent mutated genes were TET2 (71.25%), NRAS (18.75%), DNMT3A (16.25%), NPM1 (15.00%), CEBPA (13.75%). Among medium and high-risk patients, 29 underwent allo-HSCT, while 34 received chemotherapy. The 2-year overall survival (OS) rate and disease-free survival (DFS) rate of the allo-HSCT group were 72.4% and 70.2%, while those of the chemotherapy group were 44.1% and 34.0%, respectively. The statistical analysis showed significant differences between the two groups (both P < 0.01). Multivariate analysis showed that age at transplantation >50- years and occurrence of acute graft-versus-host disease after transplantation were poor prognostic factors for OS and DFS in transplantation patients. CONCLUSION Allo-HSCT can improve the prognosis of AML patients with ASXL1 mutation.

Thoracolumbar spine fracture often leads to severe pain, functional impairments, and neurological deficits, for which open reduction and internal fixation can effectively restore the spinal structural stability. Open decompression and reduction with internal fixation can help relieve spinal cord compression and improve spinal function in cases of concomitant cord injury. Although spinal stability can be restored through surgery, patients often face chronic pain and functional impairments postoperatively. A postoperative rehabilitation program is critical in optimizing therapeutic outcomes, reducing complications, and minimizing the risk of secondary injuries. However, current rehabilitation methods, such as physical therapy, functional training, and pain management, are confronted with problems in clinical practice, including significant variation in efficacy, poor patient adherence, and prolonged rehabilitation period. There is an urgent need for a unified rehabilitation strategy to address these problems. To this end, the Spinal Trauma Group of the Orthopedic Physicians Branch of the Chinese Medical Association and the Spine Health Professional Committee of the Chinese Human Health Technology Promotion Association organized experts from relevant fields to formulate Evidence-based guidelines for rehabilitation treatment after internal fixation of thoracolumbar spine fracture in adults ( version 2025) by integrating evidences from clinical researches and advanced rehabilitation concepts at home and abroad. A total number of 14 recommendations concerning the rehabilitation treatment with multimodal analgesia, psychological intervention, deep vein thrombosis prevention, core muscle and extremity exercise, appropriate use of braces, early weight-bearing, device-aided rehabilitation exercise, neuroregulatory therapy, rehabilitation team were put forward, aiming to standardize the post-operative rehabilitation process following internal fixation, promote the functional recovery, and enhance patients′ quality of life.

Acute symptomatic osteoporotic thoracolumbar compression fracture (ASOTLF) can lead to chronic low back pain, kyphosis deformity, pulmonary dysfunction, loss of mobility, and even life-threatening complications. Vertebral augmentation is currently the mainstream treatment method for this condition. In 2019, the Editorial Board of Chinese Journal of Trauma and the Spinal Trauma Group of Orthopedic Surgeons Branch of Chinese Medical Doctor Association collaboratively led the development of Clinical guideline for vertebral augmentation for acute symptomatic osteoporotic thoracolumbar compression fractures. Six years later, with advances in clinical diagnosis and treatment techniques as well as accumulating evidence in related fields, the 2019 guideline requires updating. To this end, the Spinal Trauma Group of Orthopedic Surgeons Branch of Chinese Medical Doctor Association, the Spinal Health Professional Committee of China Human Health Science and Technology Promotion Association, and the Minimally Invasive Orthopedics Professional Committee of Shaanxi Medical Doctor Association have organized experts in the field to develop the Clinical guideline for vertebral augmentation of acute symptomatic osteoporotic thoracolumbar compression fractures ( version 2025) , based on the latest evidence-based medical researches. This guideline incorporates 3 recommendations retained from the 2019 version with updated strength of evidence, along with 12 new recommendations. It provides recommendations from six aspects of diagnosis, pain management, treatment option selection, prevention of postoperative complications, anti-osteoporosis therapy, and postoperative rehabilitation, aiming to provide a reference for standard treatment of vertebral augmentation for ASOTLF in hospitals at all levels.

The co-infection of HIV and Mycobacterium tuberculosis (MTB) poses a severe challenge for the prevention and control of infectious disease, resulting in poor clinical outcomes of the patients and risk for wide spread. As steady progress in global health, the co-infection of HIV/MTB has been basically controlled, and the new cases are generally declining. However, its incidence remained high in resource-limited areas. The incidence of the co-infection of HIV/MTB is associated with the interaction among individual, social, health service, and natural factors. Comprehensive measures are needed to reduce this disease burden. This paper summarized the epidemiological characteristics of the co-infection of HIV/MTB and influencing factors both at home and abroad to provide evidence for the identifications of high-risk populations and areas and development of targeted prevention measures for the purpose of reduce the incidence of co-infection of HIV/MTB.
