ObjectiveTo evaluate the efficacy and safety of Janus kinase （JAK） inhibitors combined with Chinese herbal medicine （CHM） in treating rheumatoid arthritis （RA）. MethodsClinical data from 169 RA patients were retrospectively collected. Among them， 71 cases received JAK inhibitors as the control group， while 98 cases received JAK inhibitors plus CHM as the observation group， both treated for 24 weeks. The rheumatoid factor （RF）， cyclic citic peptide antibody （anti-CCP）， erythrocyte sedimentation rate （ESR）， C-reactive protein （CRP）， and white blood cell count （WBC） were recorded before and after treatment. Databases including CNKI， Wanfang， VIP， PubMed and Web of Science were searched from inception till August 31st， 2025 for randomized controlled trials （RCTs） on the combined use of JAK inhibitors and CHM for RA. The methodological quality of the included studies was evaluated using the risk of bias assessment tool. Meta-analyses were performed for RF， anti-CCP， ESR， CRP， 28-joint disease activity score （DAS28）， overall clinical effective rate， and incidence of adverse events. Sensitivity analysis were also performed. ResultsThe retrospective study demonstrated that after treatment， ESR， CRP， and anti-CCP levels decreased in the observation group， while ESR and CRP levels decreased in the control group （P＜0.05）. Moreover， ESR and RF levels in the observation group were lower than those in the control group （P＜0.05）. A total of 9 RCTs involving 770 patients were included in the meta-analysis. The results indicated that the JAK inhibitors plus CHM group was superior to the JAK inhibitors group in reducing RF （MD=-8.97， 95%CI -15.01 to -2.94， P=0.004）， CRP （MD=-3.34， 95%CI -3.82 to -2.86， P＜0.001）， ESR （MD=-5.33， 95%CI -7.98 to -2.69， P＜0.001）， and DAS28 score （MD=-0.54， 95%CI -0.74 to -0.34， P＜0.001）， as well as in improving the overall clinical effective rate （OR=4.53， 95%CI 2.55 to 8.03， P＜0.001）. No statistically significant differences were observed between groups in anti-CCP levels （SMD=-2.08， 95%CI -4.41 to 0.24， P=0.080） or incidence of adverse events （OR=0.93， 95%CI 0.55 to 1.57， P=0.790）. ConclusionThe combination of JAK inhibitors and CHM demonstrates remarkable efficacy in treating RA， contributing to improved disease activity and reduced inflammatory markers with a favorable safety profile.

Background/Aims: Cholangiocarcinoma (CCA) is a primary malignant neoplasm with an extremely poor prognosis. While combined chemoradiotherapy has been demonstrated to delay CCA progression to a certain extent, the absence of specific molecular biomarkers or targets significantly hinders the diagnosis and treatment of CCA. Methods: Through cross-analysis of proteomics and ADMA modificationomics, we identified DDX1 overexpressed in CCA with elevated R602-ADMA modifications. HPLC-MS/MS identified PRMT1 as the methyltransferase and USP10 as the deubiquitinating enzyme for DDX1. Immunofluorescence and nuclear-cytoplasmic partitioning experiments confirmed DDX1’s nuclear localization. GO and KEGG analyses clarify the biological functions of DDX1 in response to hypoxia. RNA-seq transcriptomics analyzed key pathways influenced by DDX1. A hydrodynamic in situ CCA mouse model was established to validate the chemopreventive effects of the PRMT1-specific inhibitor GSK715 on CCA development. Results: DDX1 promotes CCA progression both in vivo and in vitro and can be inhibited by GSK715. Mechanistically, PRMT1 mediates ADMA modification at position R602 of DDX1. This modification promotes DDX1 nuclear localization by recruiting USP10 to deubiquitinate DDX1, while simultaneously inhibiting PRMT1 degradation. DDX1 promotes the transcription of PRMT1 and USP10 by binding to the mRNA 3’UTR region, establishing a positive feedback regulatory pathway. This mechanism promotes the occurrence and development of CCA and can serve as a target for the inhibitor GSK715 to suppress CCA progression. Conclusions Our study identified DDX1-R602-ADMA modification as a novel ADMA modification in CCA. It further confirmed its pivotal role in CCA progression. Targeting the USP10-PRMT1-DDX1 axis may represent a significant therapeutic approach for CCA.

ObjectiveTo explore the association between marital/living status and cognitive domains （memory， language， visuospatial， executive， and attention domains） in older adults， and to examine the influencing factors underlying urban-rural differences. MethodsBased on baseline data from the dynamic enrollment cohort （2016—2025） of the Hubei Memory and Aging Cohort Study， 10 825 older adults aged 60 years and above who met the study criteria were included， comprising 3 788 rural residents and 7 037 urban residents. The cohort collected information on marital and living status via questionnaires. Cognitive domains were assessed using standardized neuropsychological tests， with scores converted to z-scores ［（raw score - mean score of the domain in the study population）/standard deviation of the domain in the study population］. Multiple linear regression models were used to analyze the associations between marital/living status and cognitive domains， as well as global cognition. ResultsRural older adults scored significantly lower than their urban counterparts in terms of socioeconomic status， healthy lifestyle indicators， and multiple cognitive domains （all P＜0.001）. Living away from family was significantly associated with lower scores across cognitive domains ［memory： b =-0.217， 95%CI （-0.276， -0.159）； attention： b =-0.213， 95%CI （-0.262， -0.163）， all P＜0.001］， with this association being stronger and involving a broader range of cognitive domains in the urban sample. Moreover， compared to married and living with family， married but living away from family was associated with poorer cognitive performance， an effect that was more pronounced in the urban sample ［memory： b =-0.521， 95%CI （-0.621， -0.422）； attention： b =-0.443， 95%CI （-0.533， -0.354）， all P＜0.001］. ConclusionUnmarried status and living away from family were each significantly associated with poorer performance in cognitive domains among older adults. The combined status of being married but living away from family was also associated with poorer cognitive performance， with these associations being more pronounced among urban-dwelling older adults.

Endometriosis(EMs)is a common estrogen-depend-ent clinical disease with the pathological characteristics of malig-nant tumors,which has great impact on women's physical and mental health.In recent years,experimental exploration has re-vealed that ectopic foci are in a hypoxic environment outside the uterine cavity,and mitochondria,as the"functional factories"of the cells,play an important role in the process of planting and in-vasion,and the mitochondrial quality control system,which in-cludes mitochondrial oxidative stress,kinetics,autophagy,bio-genesis and calcium homeostasis,is a key mechanism for the e-quilibrium of the mitochondrial function.The mitochondrial quality control system,including mitochondrial oxidative stress kinetics,autophagy,biogenesis and calcium homeostasis,is a key mechanism for mitochondrial functional balance.Therefore,to clarify the role of the mitochondrial quality control system in the development of EMs with the help of rational and rigorous experi-mental and clinical studies can not only help to clarify the patho-genesis of the disease,but also explore the key targets in the prevention and treatment of the disease.Therefore,this article summarizes the research progress of mitochondrial quality control system in endometriosis,with a view to providing reference and theoretical basis for the etiology,pathogenesis and prevention strategies of EMs.

Objective To study the application of autologous natural killer(NK)cells in the treatment of advanced renal cell carcinoma and the changes of immune function and tumor markers in patients.Methods 61 patients with advanced renal cell carcinoma admitted to Gansu Wuwei Tumour Hospital from March 2023 to April 2024 were divided into targeting group(31 cases,given supportive treatment combined with sunitinib malate capsules)and cell group(30 cases,autologous NK cells combined with targeting group)according to the patient's willingness to treat combined with propensity score matching.6 weeks was a treatment cycle,and all patients were treated for 4 cycles.The clinical efficacy of the two groups after 4 cycles of treatment and the occurrence of adverse reactions during treatment were statistically analyzed.The levels of serum cytokines,tumor markers,lymphocyte function and immune function were compared between the two groups before and after 4 cycles of treatment.Results After 4 cycles of treatment,the objective remission rate and disease control rate in the cell group were higher than those in the targeting group(P<0.05).After 4 cycles of treatment,the levels of serum hypoxia-inducible factor-1α(HIF-1α),vascular endothelial growth factor(VEGF),platelet-derived growth factor(PDGF),carcinoembryonic antigen,carbohydrate antigen 125,carbohydrate antigen 199 and alpha-fetoprotein in the two groups were lower than those before treatment,and those in the cell group were lower than those in the targeting group(P<0.012 5).After 4 cycles of treatment,the levels of serum interleukin-2,interleukin-6,tumor necrosis factor-β,interferon-γ,peripheral blood CD3+,CD4+,NK cells and CD4+/CD8+in the two groups were higher than those before treatment.The levels of serum interleukin-2,tumor necrosis factor-β,interferon-γ,peripheral blood CD3+and NK cells in the cell group were higher than those in the targeting group(P<0.012 5).The level of CD8+in peripheral blood was lower than that before treatment(P<0.012 5),but there was no significant difference between the two groups(P>0.012 5).During the treatment,there was no significant difference in the incidence of diarrhea,nausea and vomiting,alopecia,liver function damage,decreased platelet level and decreased neutrophil level between the cell group and the targeting group(P>0.05).Conclusion The treatment of advanced renal cell carcinoma with autologous NK cells could improve the level of serum cytokines,reduce the level of tumor markers,regulate the function of lymphocytes and immune function,and had a good therapeutic effect.At the same time,it would not increase the incidence of adverse reactions,and the safety was good.

Objective:To explore the clinical efficacy of the sixth generation CyberKnife (M6) in treating patients with brain metastases, and analyze clinical characteristics and dosimetric factors.Methods:Clinical data of patients with brain metastases who received CyberKnife treatment at Sichuan Cancer Hospital from April 2023 to March 2024 were retrospectively analyzed. All patients were treated with CyberKnife with 6 MV X-ray. According to the maximum diameter of brain metastases, the radiation prescription dose of brain metastases was adjusted. The tumor remission, recurrence, 6-month and 1-year overall survival (OS), local control (LC) of intracranial target lesions, progression-free survival (PFS), distant metastasis-free survival (DMFS) of intracranial brain metastases and adverse reactions were evaluated. According to the median biological dose, the survival difference between the groups was compared. Survival analysis was conducted by Kaplan-Meier method. Survival differences among different groups were analyzed by log-rank test.Results:A total of 63 eligible patients with brain metastases were enrolled, with a median age of 59 years (rang: 36-80 years). Among them, 47 patients were diagnosed with primary tumors originating from the lungs, 16 patients with primary tumors originating from other organs; 44 patients with single brain metastases, and 19 patients with 2-3 lesions, respectively. The median biological dose was 67.2 Gy (rang: 47.4-86.4 Gy), and the median single dose was 8 Gy/F (rang: 4-24 Gy/F). The follow-up was conducted until July 15, 2024. The median follow-up time for the entire group was 9 months (rang: 2-15 months). Among the 87 target lesions treated with CyberKnife, 11 patients corresponding to 14 target lesions experienced local recurrence. And the 6-month and 1-year LC rates were 92.5% and 70.9%, respectively. Ten patients corresponding to 16 target lesions died. And the 6-month and 1-year OS rates were 92.7% and 74.8%, respectively. Thirty-five patients corresponding to 50 target lesions experienced disease progression. And the 6-month and 1-year PFS rates were 64.3% and 25.5%, respectively. Thirty-three patients corresponding to 48 target lesions showed distant metastasis outside the target lesions, with a 6-month DMFS of 67.0% and a 1-year DMFS of 33.9%. Group comparison showed that 43 target lesions in the group receiving ≤67.2 Gy irradiation and 44 in the group receiving >67.2 Gy irradiation. The 6-month LC, OS, PFS, and DMFS rates between two groups were 89.8% vs. 97.7% ( P=0.127), 89.8% vs. 95.4% ( P=0.305), 65.4% vs. 68.5% ( P=0.514), 65.4% vs. 68.5% ( P=0.516), respectively. The 1-year LC, OS, PFS, and DMFS rates between two groups were 54.1% vs. 89.5% ( P=0.003), 67.3% vs. 82.9% ( P=0.219), 19.2% vs. 32.7% ( P=0.370) and 23.3% vs. 33.0% ( P=0.533). During the follow-up, only 2 patients (3.2%) were found to have grade 1-2 radiation-induced brain injury (asymptomatic brain injury) by MRI examination, and there were no other radiotherapy related adverse reactions. Conclusions:CyberKnife therapy is clinically effective for brain metastases, with mild adverse reactions. Increasing the tumor irradiation dose can improve local tumor control and is expected to further improve the OS of patients.

The top 5 bacterial species were Escherichia coli（50.0%）， Klebsiella pneumoniae（26.1%）， Pseudomonas aeruginosa（5.1%）， Acinetobacter baumannii complex（5.0%）and Enterobacter cloacae complex（4.1%）. The ESBL-producing rates in Escherichia coli， Klebsiella pneumoniae and Proteus mirablilis were 46.8%（2 685/5 741），18.3%（549/2 999）and 44.0%（77/175），respectively. The prevalence of carbapenem-resistant Escherichia coli（CREC）and carbapenem-resistant Klebsiella pneumoniae（CRKP）were 1.3%（76/5 741）and 15.0%（450/2 999）；32.9%（25/76）and 78.0%（351/450）of CREC and CRKP were sensitive to ceftazidime/avibactam combination，respectively. 94.7%（72/76）and 90.2%（406/450）of CREC and CRKP were sensitive to aztreonam/avibactam combination. Furthermore，57.9%（44/76）and 79.1%（356/450）were sensitive to imipenem/relebactam combination. The prevalence of carbapenem-resistant Acinetobacter baumannii（CRAB）complex was 64.6%（370/573），while more than 80.0% of CRAB complex was sensitive to tigecycline，eravacycline and polymyxin B. The prevalence of carbapenem-resistant Pseudomonas aeruginosa（CRPA）was 17.0%（99/581）. There were differences in the composition ratio of Gram-negative bacteria in bloodstream infections and the prevalence of important Gram-negative bacteria resistance among different regions in China，with statistically significant differences in the prevalence of CREC，CRKP，CRPA and CRAB complex（ χ2=10.6，28.6，10.8 and 19.3， P<0.05）. The prevalence of ESBL-producing Escherichia coli， CREC，CRAB complex and CRKP were higher in provincial hospitals than those in municipal hospitals（ χ2=12.5，9.8，12.7 and 57.8，all P<0.01）. Conclusions:Gram-negative bacteria are the main pathogens causing bloodstream infections in China，and Escherichia coli is ranked in the top，while the trend of Klebsiella pneumoniae increases continuously with time. CRKP infection shows a slow upward trend，CREC infecton maintains a low prevalence level，and CRAB complex infection continues to exhibit a high prevalence rate. The composition and resistance patterns of pathogens causing bloodstream infections vary to some extent across different regions and levels of hospitals in China.

Objective:To analyze the clinical value of mannan binding lectin associated serine protease 2 (MASP-2), galectin-3, and midkine in the differential diagnosis of thyroid nodules.Methods:From March 2021 to March 2022, 75 patients (study group) with thyroid nodules admitted to the Nanchong Hospital of Traditional Chinese Medicine and 50 volunteers(control group) who underwent health examinations during the same period were retrospectively selected. The levels of MASP-2, galectin-3 and midkine were compared between the two groups, and the levels of MASP-2, galectin-3 and midkine in benign and malignant thyroid nodules in the study group were compared. The predictive value of MASP-2, galectin-3, midkine and combined tests for malignant thyroid nodules diagnosis was analyzed by receiver operating characteristic (ROC) curve.Results:The levels of MASP-2, galectin-3, midkine in the study group were higher than those in the control group: (433.92 ± 35.01) mg/L vs. (215.12 ± 22.60) mg/L, (26.73 ± 3.12) μg/L vs. (20.51 ± 2.10) μg/L, (258.96 ± 27.03) ng/L vs. (122.47 ± 15.72) ng/L, there were statistical differences ( P<0.05). The levels of MASP-2, galectin-3, midkine in the patients with malignant nodules were higher than those in the patients with benign thyroid nodules: (541.27 ± 57.35) mg/L vs. (400.02 ± 30.17) mg/L, (41.68 ± 5.23) μg/L vs. (22.01 ± 2.89) μg/L, (318.97 ± 40.23) ng/L vs. (240.01 ± 25.01) ng/L, there were statistical differences ( P<0.05). ROC curve analysis showed that the area under the curve (AUC) of MASP-2, galectin-3 and midkine in the diagnosis of malignant thyroid nodules was the highest (0.819), which was higher than that of any single index. Conclusions:The serum levels of MASP-2, galectin-3 and midkine in patients with malignant nodules were higher than those in patients with benign nodules, and the combined value of MASP-2, galectin-3 and midkine is higher in predicting malignant thyroid nodules.

Objective To explore the feasibility and safety of ultrasound-guided percutaneous microwave ablation for unresectable pancreatic cancer.Methods Totally 84 patients who underwent ultrasound-guided percutaneous microwave ablation for unresectable pancreatic cancer were enrolled,and the technical success rate,complete ablation rate,complication rate,pain relief rate and survival time,etc.were observed.Results The median age of 84 cases was 61.5 years.Totally 86 tumors,including 44.19％(38/86)at the head/neck and 55.81％(48/86)at the body/tail of pancreas were detected,and a total of 85 ablation sessions were performed with the median ablation energy applied per tumor of 9.90(1.08,21.60)kJ and the complete ablation rate of 42.86％(36/84).The technical success rate was 100％(85/85).Thirty-nine complication events occurred in 25 cases,no ablation-related death.Among 34 patients underwent ablation mainly for pain symptoms,the pain score decreased from(6.22±1.12)points before treatment to(1.94±1.64)points after treatment(P＜0.001).During 6.8(3.3,12.9)months' follow-up,the mean survival time was(8.5±6.7)months,and all 47 patients died due to tumor progression.Conclusion Ultrasound-guided percutaneous microwave ablation was safe and feasible for unresectable pancreatic cancer.
