Rheumatoid arthritis （RA） is a common chronic systemic autoimmune disease with synovitis as the main manifestation， which often causes joint swelling and pain or even deformity. It is considered to be an incurable lifelong disease. Although the current Western medicine treatment can alleviate the progression of the disease， it has the clinical limitations of liver injury， cardiovascular complications， and other adverse reactions， along with easy recurrence. Traditional Chinese medicine （TCM） has a long history and has the advantages of individualized treatment and fewer adverse reactions. It can effectively relieve the symptoms of joint swelling and pain in RA patients and slow down the progression of bone destruction， which has attracted wide concern in the medical community. Janus kinase （JAK）/signal transducer and activator of transcription （STAT） signaling pathway is an important intracellular pathway involved in cell proliferation， differentiation， apoptosis， immune regulation， and other biological behaviors， and plays an important role in the pathophysiological process of RA. In recent years， many studies have confirmed that TCM monomers and compounds can inhibit inflammation and angiogenesis by regulating the JAK/STAT signaling pathway， induce apoptosis and inhibit proliferation of fibroblast-like synoviocytes （FLS）， regulate immune response， and thus exert an effect in the treatment of RA. However， there is still a lack of comprehensive and systematic induction and overview. Therefore， by searching the relevant literature in China National Knowledge Infrastructure （CNKI） and PubMed databases from 2009 to 2024， this study described the mechanism of the JAK/STAT signaling pathway in the occurrence and development of RA and summarized the research progress of TCM monomers and compounds in regulating the JAK/STAT signaling pathway in RA intervention. The study aims to provide new ideas and strategies for the clinical treatment of RA with TCM and the research and development of new drugs.

OBJECTIVE: To explore the clinical and genetic features of a child with Pontocerebellar hypoplasia type 2B (PCH2B) due to compound heterozygous variants of the TSEN2 gene. METHODS: A PCH2B patient presented at Department of Pediatric Neurology, Xiangya Hospital of Central South University in June 2023 was selected as the study subject. Clinical data of the patient were retrospectively analyzed. The patient and her parents were subjected to whole exome sequencing and bioinformatic analysis. Pathogenicity of the candidate variants were classified based on the guidelines from the American College of Medical Genetics and Genomics (ACMG). A literature review was also conducted by searching the China National Knowledge Infrastructure (CNKI), Wanfang Data, and PubMed databases from their establishment to May 2025 using keywords "TSEN2 gene" "PCH2B" and "Pontocerebellar Hypoplasia 2B" to summarize the clinical and genotypic features of patients with PCH2B due to variants of the TSEN2 gene. This study was approved by the Medical Ethics Committee of the Hospital (No.: #202310892). RESULTS: The patient, a 6-year-5-month-old girl, had exhibited severe global developmental delay, developmental regression, autism spectrum disorder, myoclonus of eyelids, feeding difficulty, irritability, progressive microcephaly, esotropia, and hypotonia. MRI showed reduced volume of bilateral cerebellar hemispheres and vermis. Genetic testing revealed that she has harbored compound heterozygous variants of the TSEN2 gene (NM_025265.4), namely c.1054A>T (p.Lys352*) and c.899G>T (p.Ser300Ile), which were inherited from her father and mother, respectively. Both variants were classified as likely pathogenic based on the ACMG guidelines and were previously unreported. Literature review has identified six PCH2B patients with missense, nonsense, frameshift, and splice site variants of the TSEN2 gene. Their main clinical manifestations included global developmental delay, progressive microcephaly, feeding difficulties, irritability, and vermis hypoplasia. Cranial MRI and genetic testing are crucial for definite diagnosis. CONCLUSION The c.1054A>T (p.Lys352*) and c.899G>T (p.Ser300Ile) compound heterozygous variants of the TSEN2 gene probably underlay the pathogenesis in this patient. Above findings has expanded the genotypic and phenotypic spectra of TSEN2-related PCH2B, and offered guidance for genetic counseling for this family.

Parkinson's disease （PD） is a common neurodegenerative disorder characterized by motor impairments， with its pathological mechanisms involving multiple processes such as the degeneration of dopaminergic neurons and the abnormal aggregation of α-synuclein. Current Western medical treatments face challenges including diminished long-term efficacy and motor complications. In recent years， Traditional Chinese Medicine （TCM） has demonstrated advantages in the prevention and treatment of PD through its systematic regulatory capabilities， featuring multi-component， multi-target， and multi-pathway approaches.This article systematically reviews the roles of seven key signaling pathways-NF-κB， AMPK/mTOR， PI3K/Akt， MAPKs， Nrf2/ARE， Wnt/β-catenin， and BDNF/TrkB-in the pathological process of PD and the regulatory mechanisms of TCM. Research indicates that active ingredients of Chinese herbs and compound formulations can synergistically modulate these pathways， exerting comprehensive effects in inhibiting neuroinflammation， alleviating oxidative stress， promoting autophagy to clear abnormal proteins， and enhancing neurotrophic support. These signaling pathways form a complex regulatory network through crosstalk among key nodal molecules， constituting an intricate regulatory system in PD pathology. The multi-target intervention characteristics of TCM align well with this network-based regulatory requirement， achieving integrated anti-inflammatory， antioxidant， autophagy-regulating， and neurorestorative effects through synergistic multi-pathway modulation. This article systematically outlines the mechanisms of TCM in the coordinated regulation of multiple pathways， providing a theoretical basis for elucidating the pathological process of PD and the intervention mechanisms of TCM， while also offering new perspectives and directions for modern research on TCM in the prevention and treatment of PD.

With the rising incidence of colon cancer, several studies have indicated that aquaporin 1 (AQP1) expression is associated with the development of colon cancer. This study aims to elucidate the potential molecular mechanisms between them. Methods: We screened data from The Cancer Genome Atlas (TCGA) database and retrospectively examined AQP1 protein expression in 127 colon cancer patients to analyze the relationship between AQP1 expression and pathological stages, prognosis. We created stable colon cancer cell lines with differential AQP1 expression, the effect of AQP1 expression on the proliferation and migration of colon cancer cells was assessed by in vitro and in vivo studies, and explored potential molecular mechanisms through Western blotting. Results: High AQP1 expression was associated with poorer survival (overall survival [OS], p = .028) in colon cancer patients from the TCGA database. Similarly, retrospective clinical data indicated that high AQP1 expression was associated with reduced disease-free survival and OS (p = .036 and p = .017, respectively). The low-expressing AQP1 colon cancer cells exhibited a decrease in proliferation and migration ability of colon cancer cells compared to the overexpressing AQP1 group (p < .05) in vitro and in vivo. Immunohistochemistry and western blotting experiments validated heightened expression of N-cadherin, vimentin, and claudin- 1 in the tumor tissues of the overexpressing AQP1 group. Conversely, reduced AQP1 expression resulted in decreased expression of claudin- 1. Conclusions: AQP1 correlates with unfavorable prognosis in colon cancer and potentially enhances the proliferation and migration of colon cancer by up-regulating claudin-1 expression.

Aortic dissection is a serious cardiovascular disease characterized by acute onset and high mortality rates. Although advancements in surgical techniques and anesthesia methods have significantly reduced surgical mortality, postoperative complications, particularly pulmonary complications, remain a challenge for the recovery of patients with aortic dissection. Existing studies indicate that respiratory rehabilitation plays a crucial role in preventing and alleviating postoperative pulmonary complications, and its application is gradually expanding. However, current understanding of respiratory rehabilitation treatment for patients with aortic dissection is still insufficient, and there is a lack of standardized protocols in clinical practice. This article aims to review the existing research evidence, comprehensively analyze common pulmonary complications after aortic dissection surgery, their pathogenesis, the latest advancements in perioperative respiratory rehabilitation, and the main challenges faced, in order to provide references for clinical practice and future research.

Objective To introduce the calculation of the DISO index in multi-dimensional data ranking for disease surveillance, and evaluate its applicability. Methods Using the data from the quality supervision and inspection of infectious disease reporting in Jingzhou City in a certain year as an example, the DISO index was used to rank 16 investigated medical institutions and compared with the TOPSIS method. The consistency between the two evaluation results was analyzed using Spearman correlation. Then, The DISO index from different medical institutions was used to evaluate the ranking of 8 counties (cities, districts). The evaluation indicators for the supervision and inspection included six items: report rate, timely report rate, completeness of report card filling, accuracy of report card filling, consistency rate with network information report, and completeness of valid ID number filling. Results Among the 16 medical institutions, 8 institutions had all six evaluation indicators at 100%. Using the two methods to rank the 16 medical institutions, the two methods showed that the 8 medical institutions with all six evaluation indicators at 100% were ranked first. There was a strong correlation between the rankings of the 16 medical institutions using the two methods (r_s=0.992, P=0.000). The three counties (cities, districts) with all six evaluation indicators at 100% were all ranked first, while country G was ranked seventh and country E was ranked eighth. Conclusion The results of the DISO index and the TOPSIS method were similar in one-dimensional ranking. DISO can be used for multi-dimensional ranking of disease surveillance data and deserves to be promoted and applied.

OBJECTIVE To evaluate the efficacy and safety of rituximab （RTX） in the treatment of primary Sjögren syndrome （pSS）. METHODS Randomized controlled trials （RCTs） on the effects of RTX （trial group） versus placebo （control group） in the treatment of pSS were searched from the Cochran Library， PubMed， Embase， Medline， Web of Science， VIP， CNKI， Wanfang， and other databases during the inception to February 2024. After literature screening and quality evaluation， meta-analysis was performed by using RevMan 5.3 software. RESULTS Seven RCTs were finally included， involving a total of 518 patients. Results of meta-analysis showed that European League Against Rheumatism Sjögren syndrome disease activity index （ESSDAI） score [MD＝－1.17， 95%CI（－1.52， －0.82）， P＜0.000 01] and oral dryness visual analogue scale （VAS） score [MD＝－3.97， 95%CI （－5.08， －2.86）， P＜0.000 01] in the trial group were significantly lower than the control group； unstimulated salivary flow rate [SMD＝0.64， 95%CI（0.41， 0.87）， P＜0.000 01] and Schirmer score [MD＝0.19， 95%CI（0.18， 0.20）， P＜0.000 01] were significantly higher than the control group. There was no statistical significance in response rate [RD＝0.10， 95%CI（－0.04， 0.23）， P＝0.16]， fatigue VAS score [MD＝－12.50， 95%CI（－35.14， 10.15）， P＝0.28]， European League Against Rheumatism Sjögren syndrome patient reported index （ESSPRI） score [MD＝0.33， 95%CI（－0.53， 1.18）， P＝0.46]， Short-form 36 health survey physical component summary （SF36-PCS） score [MD＝0.90， 95%CI（－2.97， 4.78）， P＝0.65]， SF-36 mental component summary （SF36-MCS） score [MD＝0.11， 95%CI（－0.41， 0.63）， P＝0.68]， total salivary gland ultrasound score [SMD＝－1.91， 95%CI（－4.01， 0.19）， P＝0.07] or the incidence of adverse drug reactions [OR＝1.15，95%CI（0.62，2.13），P＝0.66] between 2 groups. CONCLUSIONS RTX has advantages in the improvement of ESSDAI score， unstimulated salivary flow rate， Schirmer score and oral dryness VAS score in pSS patients， and has a good safety profile. However， it did not exhibit significant improvement in fatigue VAS score， ESSPRI score， SF36-PCS score， SF36-MCS score or response rates.

Alzheimer disease(AD)is a progressive neurodegenerative disorder characterized by cognitive dysfunction and declining learning and memory abilities,significantly impacting daily lives and behavioral capacities of the patients.The mitogen-activated protein kinase(MAPK)signaling pathway,primarily composed of extracellular signal-regulated kinase,p38 MAPK,and c-Jun N-terminal kinase.Mounting evidence suggests that the MAPK signaling path-way is intimately linked to the pathogenesis of AD,providing crucial insights into the disease's progression.In recent years,traditional Chinese medicine(TCM)has demonstrated promising potential in treating AD,with its advantages of personalized therapy and multi-target regulation garnering increasing research attention.This study aims to review the ex-perimental research landscape of TCM interventions targeting the MAPK signaling pathway for the prevention and treat-ment of AD over the past five years.The findings reveal that effective compounds and herbal formulas in TCM,such as isorhamnetin,nobiletin,parthenolide,Glehnia littoralis,Ishige okamurae,shikonin,artemisinin,kaempferol,myrice-tin,and Tripterygium glycosides,can alleviate AD symptoms by modulating the MAPK signaling pathway.These interven-tions mitigate Aβ-induced neuronal damage,reduce Tau protein hyperphosphorylation,and suppress neuroinflammatory responses.The objective of this review is to provide a scientific and theoretical reference for the clinical prevention and treatment of AD and to inform the development of novel therapeutic agents.

Stratified diagnosis and treatment is a crucial approach in precision medicine， aiming to optimize medical care by grouping patients based on clinical manifestations， biomarkers， and pathological characteristics. Based on clinical stages， symptoms， age， gene expression， and pathology， research on Sjögren's syndrome （SS） has proposed various stratification methods， incorporating both traditional Chinese medicine （TCM） and Western medicine perspectives. These methods provide essential support for early diagnosis， risk assessment， and personalized treatment. Key strategies include moving SS intervention time forward， to leverage TCM's preventive principles， integrating TCM and Western tools to enhance precision， innovating clinical trial designs， developing multifactorial risk prediction models and digital imaging technologies， and constructing combined prognostic models for personalized follow-up and big data-driven treatment. These insights offer a comprehensive framework for advancing SS precision medicine.

Objective To track and evaluate the implementation and application of the occupational health standard Radiation shielding requirements for radiotherapy room—Part 4: Radiotherapy room of ²⁵²Cf neutron afterloading (GBZ/T 201.4-2015) by radiation health technical service agencies, medical institutions, health supervision agencies, and radiotherapy facility design units, and to provide a scientific basis for the further revision and implementation of this standard. Methods Following the Guideline for health standards tracking evaluation (WS/T 536-2017) and the project implementation plan, relevant practitioners were randomly selected for a questionnaire survey. The survey primarily focused on their awareness, standard training, application, and revision suggestions of GBZ/T 201.4-2015. The results were summarized and analyzed. Results A total of 168 evaluation questionnaires were collected from relevant practitioners in 28 provinces. Only 31.6% of the respondents reported being “well familiar” or “ familiar” with the standard, 27.4% of the respondents believed that the standard was widely used, and 45.2% of the respondents believed that the standard could meet the needs of their work. Only 14.9% of the respondents had received relevant training on the standard, more than half of the respondents had not applied the standard within the past 10 years, and 45.2% of the respondents believed that the standard "needs to be revised". Conclusion Due to the small number of californium-252 neutron afterloading radiotherapy devices in operation on the market, the overall awareness of the standard is low, suggesting that relevant authorities need to strengthen training and publicity of the standard, and that certain sections of the standard need to be revised or merged.
