OBJECTIVE To systematically evaluate the influential factors for all-cause mortality in patients with carbapenem-resistant Gram-negative bacteria （CR-GNB） treated with polymyxin B. METHODS PubMed， Embase， the Cochrane Library， Web of Science， Wanfang Data， VIP， CBM and CNKI were searched to collect clinical studies on all-cause death within 30 days or 28 days after treatment with polymyxin B in patients with CR-GNB infection from database establishment to July 2025. After literature screening， data extraction and evaluation of literature quality， meta-analysis was performed using RevMan 5.4 software. RESULTS A total of 12 studies were included， involving 1 326 patients， among whom 529 patients died， with a mortality rate of 39.89%. Meta-analysis results showed that combined with cardiovascular disease [OR＝2.06， 95%CI （1.37， 3.09）， P ＝0.005 ] ， increased Sequential Organ Failure Assessment （SOFA） score [OR＝1.20， 95%CI （1.07， 1.35）， P ＝0.003 ] ， mechanical ventilation [OR＝2.35， 95%CI （1.65， 3.34）， P ＜0.001 ] ， continuous renal replacement therapy （CRRT） [OR＝2.58， 95%CI （1.67， 3.97）， P ＜0.001 ] ， bloodstream infection [OR＝3.24， 95%CI （2.19， 4.78）， P ＜0.001 ] ， multiple-site infection [OR＝1.51， 95%CI （1.03， 2.20）， P ＝0.03 ] ， septic shock [OR＝3.19， 95%CI （1.94， 5.24）， P ＜0.001 ] ， use of vasoactive drugs [OR＝2.90， 95%CI （1.97， 4.27）， P ＜0.001 ] ， and the occurrence of acute kidney injury （AKI） [OR＝2.17， 95%CI （1.41， 3.36）， P ＜0.001 ] were risk factors for all-cause mortality in patients with CR-GNB infection treated with polymyxin B. Conversely， an extended duration of polymy xin B treatment [OR＝0.92， 95%CI （0.86， 0.99）， P ＝0.03 ] and early administration after CR-GNB infection [OR＝0.47， 95%CI （0.25， 0.85）， P ＝0.01 ] were protective factors. CONCLUSIONS Patients with cardiovascular disease， receiving mechanical ventilation or CRRT， having bloodstream infection， multiple-site infection or septic shock， combining with vasoactive drugs， with AKI and increased SOFA scores have a higher risk of all-cause mortality. Conversely， extending the duration of polymyxin B treatment （beyond 7 days） and early administration within 48 hours after confirmed CR-GNB infection can significantly reduce the risk of all-cause mortality.

METHODS Retrieved from PubMed， Medline， Embase， the Cochrane Library， CNKI， Wanfang database， China biomedical medicine database （CBM） and VIP， clinical studies （case-control studies， cohort studies） related to influencing factors for poor prognosis of DILI were collected from inception to May 31， 2025. After literature screening， data extraction and quality evaluation of included studies， meta-analysis was carried out by using RevMan 5.4 software. RESULTS A total of 17 literature were included， involving 4 078 DILI patients， of whom 673 were in the poor prognosis group and 3 405 were in the favorable prognosis group. Meta-analysis showed that history of liver disease （OR＝2.47， 95%CI was 1.61-3.78， P ＜0.001）， alcohol drinking history （OR＝1.77， 95%CI was 1.22-2.56， P ＝0.003）， Chinese herbal medicine/Chinese patent medicine （OR＝1.87， 95%CI was 1.30-2.70， P ＜0.001）， non-hepatocellular injury type （OR＝1.70， 95%CI was 1.37-2.10， P ＜0.001）， international normalized ratio （INR） elevated （OR＝2.51， 95%CI was 1.97-3.19， P ＜0.001）， and alanine transamine （ALT） elevated （OR＝1.27， 95%CI was 1.14-1.41， P ＜0.001） were risk factors of poor prognosis in DILI. Higher albumin （ALB） level （OR＝0.47， 95%CI was 0.39-0.57， P ＜0.001）， elevated prothrombin activity （PTA） （OR＝0.88， 95%CI was 0.85-0.91， P ＜0.001） and more than 2 kinds of hepatoprotective drugs （OR＝0.62， 95%CI was 0.41-0.95， P ＝0.030） were protective factors for poor prognosis of DILI. CONCLUSIONS Patients with alcohol drinking history， history of liver disease， elevated INR， elevated ALT， taking Chinese herbal medicine/Chinese patent medicine， and non-hepatocellular injury type of DILI have a greater risk of poor prognosis， and higher ALB level， higher PTA and more than 2 kinds of hepatoprotective drugs can reduce the risk of poor prognosis of DILI.

Objective To investigate the epidemiological characteristics, influencing factors, and community dietary network drivers of clonorchiasis in Longjiang Village, Congjiang County, Guizhou Province using social network analysis from a One Health perspective, so as to provide insights into implementation of precision control measures. Methods Longjiang Village, Congjiang County, Guizhou Province was selected as a survey point. A total of 128 permanent residents at ages of over 6 years were sampled using a random sampling method, and subjects’ stool samples were collected. In addition, at least 10 fecal samples were collected from domestic cats and dogs, reservoir hosts of Clonorchis sinensis, and at least 80 freshwater snails and at least 200 freshwater fish, intermediate hosts of C. sinensis, were sampled in Longjiang Village. C. sinensis eggs were detected in human, domestic cat and domestic dog fecal samples using a modified Kato-Katz thick smear method (two slides for one stool sample) . The C. sinensis metacercariae were detected in freshwater fish with a compression method and the C. sinensis cercariae were detected in freshwater snails with a cercarial shedding method, respectively. Participants’ demographic characteristics, dietary and drinking hygiene behaviors and food-sharing relationships were collected with structured questionnaires and semi-structured in-depth interviews, and factors affecting C. sinensis infection were identified using regression analysis. Based on the north-south orientation delineated by the village river, participants were divided into groups a and b. Subjects’ food-sharing network was analyzed using social network analysis, and the Louvain algorithm was employed to investigate the community structure and key nodes of the network. Results The overall prevalence of C. sinensis infection was 33.59% (43/128) among participants in Longjiang Village, Congjiang County, Guizhou Province. The detection of C. sinensis metacercariae was 7.63% (22/288) in freshwater fish, and no C. sinensis cercariae were detected in freshwater snails. The prevalence of C. sinensis infection was 7.69% (1/13) in domestic cats, and no infection was detected in domestic dogs. Regression analysis identified age groups of 25 to 45 years [adjusted odds ratio (AOR) = 23.17, 95% confidence interval (CI): (1.85, 490.29)], Dong ethnicity [AOR = 26.80, 95% CI: (1.54, 1 105.09)], frequent consumption of raw water [AOR = 9.39, 95% CI: (1.58, 99.79)], and consumption of raw fish [AOR = 3.49, 95% CI: (1.52, 34.69)] as independent risk factors for C. sinensis infection among villagers in Longjiang Village (all P values < 0.05). Social network analysis showed a significantly higher global clustering coefficient (0.52 vs. 0.16; t = 2.41, P = 0.02) and average local clustering coefficient (0.52 vs. 0.16; t = 2.41, P = 0.02) in Group b than in Group a, and a significantly higher degree centrality was found among C. sinensis-infected individuals than among uninfected individuals in Group b (17.54 vs. 4.26; t = 2.33, P = 0.02). There was a high-risk community S11 with a 45.83% prevalence rate of C. sinensis infection in Group b, and C. sinensis-infected individuals with high betweenness centrality in Group b might serve as critical “bridges” in the food-sharing network, which facilitated the aggregation and diffusion of the risk of C. sinensis infection in the community. Conclusions Individual dietary behaviors, such as drinking raw water and consuming raw or undercooked fish, and sociocultural factors of household-neighborhood food-sharing networks, may contribute to the clustering transmission of clonorchiasis in Longjiang Village. The clonorchiasis control strategy is recommended to shift from individual-centered health education towards integrated interventions under a One Health framework in this region, which focus on key individuals within social networks, strengthen coordinated water and environmental management, and enhance community participation to improve the acceptability and sustainability of interventions.

Objective To observe hierarchical differences in brain functional networks in unilateral mesial temporal lobe epilepsy(mTLE)patients with different outcomes after surgery.Methods A total of 69 unilateral mTLE patients who underwent resection of epileptogenic lesion on the affected side were retrospectively enrolled.Based on Engel classification 1 year after surgery,the patients were divided into seizure free(SF)group and non-seizure free(NSF)group.Functional connectivity gradient analysis was employed to extract principal gradient explaining the highest variance on preoperative resting-state functional MRI(rs-fMRI),then the whole-brain gradient characteristics and principal gradient values within specific functional networks were compared between groups.Results Principal gradient connected default mode network(DMN)with sensorimotor network(SMN)along a continuous axis.Compared to SF group,NSF group showed a contracted gradient range at both ends(DMN and SMN)of the functional network and weakened hierarchical differentiation,and principal gradient value of DMN was higher,while that of SMN was lower than those in SF group(both P＜0.05).Conclusion Hierarchical differences in brain functional networks in unilateral mTLE patients with different outcomes after surgery mainly present as enhanced DMN and weakened SMN in NSF ones,and the latter two might serve as important neuroimaging markers for evaluating postoperative seizure recurrence.

Chronic pain causes physical suffering and can have major psychological impacts in patients.Chronic pain can induce depressive disorder,and clinical studies have consistently shown that chronic pain and depression frequently co-occur,suggesting the possibility of shared pathogenic mechanisms underlying these conditions.Acupuncture,as an alternative therapy,has been widely used for analgesia and to treat depression,with demonstrated clinical efficacy.The therapeutic mechanism of acupuncture is related to neural and endocrine regulation.This review considers the mechanism of chronic pain accompanied by depression,in relation to the brain regions and neural circuits affected by acupuncture treatment.This review provides a new approach for the treatment of depression caused by chronic pain.

This article reports a case of extensive ocular inflammation following zoledronic acid infusion for the treatment of osteoporosis. The patient developed pain, eyelid edema, conjunctival congestion, and decreased vision in the right eye one day after receiving intravenous zoledronic acid, and was diagnosed with uveitis, scleritis, and periorbital soft tissue inflammation. The patient′s symptoms were evaluated using the clinical activity score(CAS). After high-dose corticosteroid pulse therapy combined with other comprehensive treatments, the symptoms improved markedly. This article reviews the incidence, clinical features, potential mechanisms, management, and prognosis of ocular adverse reactions induced by zoledronic acid, and highlights the importance of early recognition and timely treatment of ocular inflammation after zoledronic acid therapy.

OBJECTIVE To analyze the influential factors for clinical efficacy of polymyxin B combined with other antibiotics in the treatment of carbapenem-resistant Acinetobacter baumannii(CRAB)pulmonary infection.METHODS A retrospective analysis was conducted on the clinical data of patients with CRAB pulmonary infection in our hospital from May 2021 to October 2024.Information such as age,gender,admitting department,infection status,underlying medical conditions,mechanical ventilation time,combination anti-infective treatment regimens,and the Acute Physiology and Chronic Health Evaluation Ⅱ(APACHE-Ⅱ)score 24 h before medication was compiled.Based on the effectiveness of the treatment,patients were divided into treatment-effective group and treatment-ineffective group.Univariate analysis and multivariate Logistic regression analysis were employed to identify independent factors influencing clinical efficacy.RESULTS A total of 156 patients were included,and 108 patients were treated effectively,with an effective rate of 69.23%.The results of univariate analysis indicated that there were statistically significant differences between 2 groups in terms of the duration of mechanical ventilation time,APACHE-Ⅱ score 24 h before medication,the number of complication types,the proportion of abnormal coagulation function,anti-infective treatment course,and hospital stay before medication(P＜0.05).The results of multivariate Logistic regression analysis showed that APACHE-Ⅱ score≥15 points 24 h before medication[OR=2.965,95%CI(1.284,6.845),P=0.020],mechanical ventilation time≥10 d[OR=3.577,95%CI(1.185,10.793),P=0.037]and hospital stay≥14 d before medication[OR=2.422,95%CI(1.036,5.654),P=0.041]were independent risk factors,and anti-infective treatment course＞7 d was a protective factor[OR=0.445,95%CI(0.221,0.895),P=0.043].CONCLUSIONS This study shows that the effective rate of polymyxin B combined with other antibiotics in the treatment of CRAB pulmonary infection is less than 70%.The mechanical ventilation time≥10 d,APACHE-Ⅱ score≥15 points 24 h before medication,and hospital stay≥14 d before medication may lead to treatment failure,whereas anti-infective treatment course＞7 d may be associated with treatment success.

BACKGROUND:Observations from several clinical studies suggest a close relationship between hypertension and osteoporosis,but the causal relationship between hypertension and osteoporosis is unclear. OBJECTIVE:To determine whether there is a causal relationship between hypertension and osteoporosis,multisite bone mineral density and osteoporosis with fractures in Asian and European populations,respectively,using a comprehensive two-sample Mendelian randomized analysis. METHODS:Data of osteoporosis in Asian populations were obtained through Japan biological bank. Data of osteoporosis in European populations were obtained from UK Biobank,a British biological bank. Data of hypertension,multisite bone mineral density and osteoporosis with fractures were all from FinnGen R10 database. Inverse variance weighted method,MR-Egger regression method,weighted median method,weighted model method and simple model method were used to study the causal relationship between hypertension and osteoporosis,multisite bone mineral density and osteoporosis with fracture in Asian and European populations. Comprehensive sensitivity analysis was used to verify the robustness,heterogeneity and level pleiotropy of the results. Stsiger test was used to determine whether there was a reverse causal relationship between osteoporosis and hypertension. RESULTS AND CONCLUSION:In Asian populations,there was no significant genetic predictive causal relationship between hypertension and osteoporosis,and there was a positive causal relationship between hypertension and calcaneal bone mineral density. In European populations,hypertension had a negative causal relationship with osteoporosis,and there was no significant causal relationship between hypertension and systemic bone mineral density,calcaneal bone mineral density,forearm bone mineral density and osteoporosis with fracture. According to the stsiger test,there was no reverse causal relationship between osteoporosis,multiplesite bone mineral density,osteoporosis with fracture and hypertension in Asian and European populations. These results indicate that there is a causal relationship between hypertension and osteoporosis,that is,in Asian populations,hypertension and calcaneal bone mineral density show a positive causal relationship;in European populations,hypertension and osteoporosis show a negative causal relationship,but no reverse causal relationship.

Objective:To investigate the magnetic resonance imaging (MRI) features of pediatric and adolescent mediastinal T-lymphoblastic lymphoma (T-LBL) and to evaluate their predictive value for early treatment response.Methods:A retrospective, multicenter case series study was conducted on 49 pediatric and adolescent patients diagnosed with mediastinal T-LBL between September 2020 and May 2024 at the Fifth Affiliated Hospital of Zhengzhou University, Beijing Gaobo Boren Hospital, and Henan Cancer Hospital.All patients underwent chest MRI, including conventional MRI sequences and diffusion-weighted imaging.Tumor imaging characteristics were analyzed, and quantitative parameters such as minimum apparent diffusion coefficient (ADCmin), maximum ADC (ADCmax), and mean ADC (ADCmean) were measured.Treatment response was evaluated 15 days post-treatment.The patients were divided into a response group (complete or partial response, 26 cases) and a non-response group (progressive disease or minor response, 23 cases).The relationship between MRI features and treatment response was analyzed.The intraclass correlation coefficient was used to assess inter-reader agreement, and independent sample t-tests and chi-square tests were employed to compare differences between groups.Receiver operating characteristic (ROC) curve analysis was conducted to evaluate the predictive performance of imaging parameters. Results:Significant differences were observed between the response and non-response groups in ADC values [ADCmin (0.80±0.41)×10 -3 mm 2/s vs.(1.23±0.70)×10 -3 mm 2/s, ADCmax (1.14±0.48)×10 -3 mm 2/s vs.(1.92±0.77)×10 -3 mm 2/s, ADCmean (0.98±0.42)×10 -3 mm 2/s vs.(1.56±0.74)×10 -3 mm 2/s] and the maximum tumor diameter was [(11.92±3.61) cm vs.(8.17±2.46) cm] (all P<0.05).ROC curve analysis showed that ADCmax had the highest predictive efficiency for treatment response, with an area under the curve (AUC) of 0.853 (95% CI: 0.790-0.910), sensitivity of 92.3%, and specificity of 65.2%.The AUC for the maximum tumor diameter was 0.814, demonstrating its excellent predictive performance. Conclusions:MRI features, particularly ADC values and the maximum tumor diameter, can effectively predict treatment response in pediatric and adolescent mediastinal T-LBL.
