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.

OBJECTIVE To explore the clinical characteristics and risk factors for refractory drug-resistant Pseudo-monas aeruginosa infection and evaluate the prognosis so as to provide theoretical bases for effective prevention and control of the refractory drug-resistant P.aeruginosa infection.METHODS A total of 95 patients who were di-agnosed with refractory drug-resistant P.aeruginosa infection and were treated in People's Hospital of Guangdong Province from Jan.2019 to Dec.2023 were assigned as the infection group.Meanwhile,95 patients who did not have drug-resistant P.aeruginosa infection,matched by the age and hospitalization period,were chosen as the non-infection group in a case-control(1∶1 ratio).The basic information and clinical data were collected from the two groups of patients.The characteristics and risk factors for the drug-resistant P.aeruginosa infection were ana-lyzed,and the prognosis of the patients was evaluated.RESULTS Among the clinical isolates of drug-resistant P.aeruginosa,78 were isolated from respiratory secretions;there were 59 patients from intensive care unit(ICU),13 patients from respiratory medicine department and 8 patients from geriatrics department.Fever,dyspnea,moist rales and cough were the major clinical manifestations.The proportions of patients with history of respirato-ry tract disease(P＜0.001),renal disease(P=0.008),nervous system disease(P=0.005),diabetes mellitus(P=0.017),hepatic disease(P=0.007),previous utilization rate of aminoglycosides(P=0.002)and previous u-tilization rate of no less than 3 types of antibiotics were higher in the infection group than in the non-infection group.Multivariate analysis showed that the history of respiratory tract disease(OR=2.813,95％CI:1.366 to 5.792,P=0.005),history of diabetes mellitus(OR=2.465,95％CI:1.129 to 5.382,P=0.024)and history of nervous system disease(OR=2.386,95％CI:1.151 to 4.944,P=0.019)were the risk factors for the drug-resist-ant P.aeruginosa infection.The mortality rate of the infection group was 30.53％,higher than 6.32％of the non-infection group(x2=18.527,P＜0.001).CONCLUSIONS The mortality rate of the patients with drug-resistant P.aeruginosa infection is high.The history of respiratory tract disease,history of diabetes mellitus and history of nervous system disease are the major risk factors for the infection.It is necessary for the hospital to strengthen the awareness of prevention of the drug-resistant P.aeruginosa infection so as to curb the hospital-associated infection.

Objective To explore the value of deep learning(DL)model based on grayscale ultrasound for predicting asymptomatic advanced chronic liver disease(cACLD).Methods Totally 258 patients with asymptomatic compensatory chronic liver diseases were retrospectively included,among them 117 with F3 or F4 stage liver fibrosis were classified into cACLD group,while 141 with F1 or F2 stage liver fibrosis were taken as non-cACLD group.The patients were divided into training set(n=180,including 82 cases of cACLD and 98 cases of non-cACLD)and validation set(n=78,including 35 cases of cACLD and 43 cases of non-cACLD)at the ratio of 7∶3.Univariate and multivariate logistic regression were used to screen independent clinical predictors of cACLD and construct a clinical model.Based on liver grayscale ultrasound,optimal DL features were extracted and screened,and Resnet50 network was adopted as framework,na?ve Bayes classifier was used to construct DL model,and a combined model was constructed based on clinical model and DL model.The efficacy and clinical value of each model for predicting asymptomatic cACLD were evaluated.Results Age,gamma-glutamyl transferase and platelet count were all independent clinical predictors of cACLD,and a clinical model was constructed.Totally 38 optimal DL features were screened to build a DL model.The AUC of combined model in training set and validation set was 0.950 and 0.740,of DL model was 0.944 and 0.737,respectively,being not significantly different(both P＞0.05)but all higher than that of clinical model(0.667 and 0.573,all P＜0.05).Taken 0.59-0.90 as the threshold,the net benefits of combined model in both training and validation sets were higher than that of other models.Conclusion DL model based on grayscale ultrasound could be used to effectively predict asymptomatic cACLD.Combining with clinical characteristics might improve clinical net benefit of this model.

Pregnancy with chronic kidney disease (CKD), particularly in stages 4-5, carries high risks of adverse outcomes including maternal renal failure, preeclampsia/eclampsia, fetal growth restriction, and preterm birth. This report described a 26-year-old woman with congenital solitary kidney, polycystic ovaries, and uterine septum due to PAX2 gene variant, complicated by CKD stage 4. Through multidisciplinary team precision management and individualized treatment strategies, including timely initiation of dialysis, the patient successfully maintained pregnancy until 34 +1 weeks and delivered a female infant via cesarean section. This case summarizes key management experiences for end-stage renal disease in pregnancy, highlighting early risk assessment, precise nutritional management, hemodialysis protocol optimization, and the crucial role of multidisciplinary collaboration, providing valuable references for managing CKD-complicated pregnancies.

Objective To investigate the mechanism by which apelin inhibits the transition from acute kidney injury(AKI)to chronic kidney disease(CKD).Methods Human proximal tubular epithelial cells were cultured in vitro and divided into control,cisplatin,cisplatin+apelin,cisplatin+apelin+Sirt3 siRNA,and apelin groups.Cells were transfected with Sirt3 siRNA and incubated with a medium containing cisplatin(10 μmol/L)and/or apelin-13(1 μmol/L).Mitochondrial morphology was observed using MitoTracker? probes;mito-chondrial membrane potential was detected using the JC-1 assay kit;and the expression of the fibrogenic cytokine,transforming growth factor β1(TGF-β1)was measured by Western blotting.Forty 10-week-old male C57BL/6J mice were divided into control,cisplatin,cisplatin+apelin,cisplatin+apelin+Sirt3 knockdown,and empty adenovirus groups,with eight mice per group.Except for the control and empty adenovirus groups,all the other groups were intraperitoneally injected with cisplatin(20 mg/kg)to establish the AKI model.The cis-platin+apelin group was intraperitoneally injected with apelin-13(0.1 μg·kg-1·d-1);the control group was injected with an equal volume of saline;the cisplatin+apelin+Sirt3 knockdown group was injected with Sirt3 knockdown adenovirus(2 × 109 pfu/mL)via the tail vein and intraperitoneal injection of apelin-13(0.1 μg·kg-1·d-1);and the empty adenovirus group was injected with adenovirus(2 × 109 pfu/mL)via the tail vein.The mice were sacrificed after 2 weeks.Kidney fibrosis was assessed by Masson's trichome staining.Type Ⅰ collagen(Col-Ⅰ)expression was observed by immunohistochemical staining.Plasma creatinine(Cr)and blood urea nitrogen(BUN)levels were measured by ELISA.Results In vitro experiments showed that,compared with the control group,the cisplatin group exhibited reduced mitochondrial fluorescence staining,decreased mitochondrial membrane potential,and increased TGF-β1 expression(all P＜0.05).Compared with the cisplatin group,the cisplatin+apelin group showed increased fluorescence staining,elevated mitochondrial membrane potential,and reduced TGF-β1 expression(all P＜0.05);however,these effects were counteracted after Sirt3 siRNA transfection.In vivo experiments showed that,compared with the control group,the cisplatin group exhibited significant renal tubular atrophy and interstitial fibrosis,increased Col-Ⅰ positive expression,and elevated plasma Cr and BUN levels(all P＜0.05).Compared with the cisplatin group,the cisplatin+apelin group showed a significant improvement in all the above indicators(all P＜0.05).Compared with the cisplatin+apelin group,the cisplatin+apelin+Sirt3 knockdown group showed a significant reduction in the renal protective effects of apelin.Conclusion The polypeptide apelin inhibits the transition from AKI to CKD by regulating Sirt3 expression to maintain mitochondrial structure and function,which can reduce renal fibrosis and improve renal function.

Objective:To analyze the latent profiles of voice behavior among head nurses and to explore the influencing factors associated with different voice behavior categories.Methods:A convenience sampling method was used to recruit 527 head nurses from 104 medical institutions across 17 provinces in East, South, Central, North, Northwest, Southwest, and Northeast China between November 2023 and January 2024. Data were collected using a General Information Questionnaire, Voice Behavior Scale, Organizational Justice Scale, General Self-Efficacy Scale, and a Brief Personality Inventory. Latent profile analysis was conducted to identify subgroups of voice behavior, and multinomial Logistic regression was performed to explore influencing factors.Results:The score of head nurses' voice behavior was (45.84±6.88). Three latent profiles were identified: low-capacity fluctuating type, medium-capacity stable type, and high-capacity promoting type. Logistic regression analysis showed that openness personality trait, organizational justice, self-efficacy, and hospital grade were significant predictors of voice behavior profiles (all P<0.05) . Conclusions:The overall level of voice behavior among head nurses is above average, with evident heterogeneity. Nursing administrators should actively encourage voice behavior, provide timely feedback, and foster a fair organizational environment to promote a positive and constructive voice culture.
