OBJECTIVE To systematically evaluate the influencing factors affecting the poor prognosis of drug-induced liver injury （DILI） in the Chinese population， and to provide evidence-based support for early identification and interventions of DILI. 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 explore the impact of number of positive regional lymph nodes (nPRLN) in N1 stage on the prognosis of non-small cell lung cancer (NSCLC) patients. Methods Patients with TxN1M0 stage NSCLC who underwent lobectomy and mediastinal lymph node dissection from 2010 to 2015 were screened from SEER database (17 Regs, 2022nov sub). The optimal cutoff value of nPRLN was determined using X-tile software, and patients were divided into 2 groups according to the cutoff value: a nPRLN≤optimal cutoff group and a nPRLN>optimal cutoff group. The influence of confounding factors was minimized by propensity score matching (PSM) at a ratio of 1 : 1. Kaplan-Meier curves and Cox proportional hazards models were used to evaluate overall survival (OS) and lung cancer-specific survival (LCSS) of patients. Results A total of 1316 patients with TxN1M0 stage NSCLC were included, including 662 males and 654 females, with a median age of 67 (60, 73) years. The optimal cutoff value of nPRLN was 3, with 1165 patients in the nPRLN≤3 group and 151 patients in the nPRLN>3 group. After PSM, there were 138 patients in each group. Regardless of before or after PSM, OS and LCSS of patients in the nPRLN≤3 group were superior to those in the nPRLN>3 group (P<0.001). N1 stage nPRLN>3 was an independent prognostic risk factor for OS [HR=1.52, 95%CI (1.22, 1.89), P<0.001] and LCSS [HR=1.72, 95%CI (1.36, 2.18), P<0.001]. Conclusion N1 stage nPRLN>3 is an independent prognostic risk factor for NSCLC patients in TxN1M0 stage, which may provide new evidence for future revision of TNM staging N1 stage subclassification.

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.

Objective:To investigate effective strategies to reduce the high risk of recurrence after allogeneic hematopoietic stem cell transplantation(allo-HSCT)in patients with minimal residual disease(MRD)-positive B-lineage acute lymphoblastic leukemia(B-ALL).Methods:A retrospective analysis was performed for ten B-ALL patients with positive MRD before transplantation at our center from November 2022 to November 2024.There were four male patients and six female patients,with a median age of 30(7-56)years.Of all patients,four received transplantation from unrelated donors,and six received haploidentical transplantation from relatives.All ten patients received blinatumomab(28 μg/day for 14 days for patients≥45 kg;5 μg/m2/day for 14 days for patients<45 kg)and were bridged to the conditioning regimen for allo-HSCT within 7 days.Results:After treatment with blinatumomab,all ten patients achieved the clearance of MRD.After allo-HSCT,100%of the patients achieved donor hematopoietic reconstitution.The median time to neutrophil reconstitution was 12(9-22)days,and the median time to platelet reconstitution was 13.5(9-22)days.As of January 2025,the median observation time was 14(2-26)months;of all patients,two experienced recurrence,and one had positive MRD again,with a recurrence rate of 20%.Among the ten patients,nine survived and one died of disease recurrence.One patient achieved complete re-mission again after chimeric antigen receptor T-cell(CAR-T)therapy following recurrence,and the patient with positive MRD achieved the clearance of MRD again after interleukin-2 treatment;both patients were currently alive.During treatment,one patient developed cytokine release syndrome,one patient was comorbid with SARS-CoV-2 infection,one patient had herpes zoster and viral encephalitis,three patients developed grade Ⅰ-Ⅱ acute graft-versus-host disease,and four patients developed chronic graft-versus-host disease;no transplantation-associated thrombotic microangiopathy was observed.Conclusion:For patients with MRD-positive B-ALL,blinatumomab as a bridge therapy for allo-HSCT can significantly reduce recurrence after transplantation,with fewer complica-tions that are easy to control.Multicenter randomized controlled clinical studies can be performed to further verify its efficacy and safety.

Under the trend of increasing aging， integrated elderly care and medical services is an important measure to optimize the supply of elderly care services and promote the good death of the elderly. Using the cooperative production theory and the classical grounded theory， a qualitative analysis was conducted on 38 cases of elderly palliative care and 25 cases of hospital-based palliative care under the integrated elderly care and medical services model from a hospital in Nanning City using Nvivo 20.0 software. This paper found that the integrated elderly care and medical services mode emphasized the deep integration of medical and elderly care services by integrating resources and improving service efficiency， to achieve the basic experience of comprehensive health care for the elderly. The promotion of these experiences has a positive significance for building a multi-agent cooperative production system， strengthening personnel training， perfecting the performance distribution mechanism， and further promoting the development of the national palliative care pilot.

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.

Objective To observe the value of machine learning(ML)models based on brain functional network features combining clinical indicators for predicting postoperative outcomes of patients with drug-resistant mesial temporal lobe epilepsy(DR-mTLE).Methods Totally 84 patients with unilateral DR-mTLE who underwent surgery were retrospectively enrolled and classified into seizure free(SF)group(n=55)and non-seizure free(NSF)group(n=29)according to one-year postoperative follow-up.Clinical data were analyzed to screen independent predictors of postoperative outcomes.Based on brain preoperative resting-state functional MRI,brain functional networks were constructed using graph theory analysis,and 587 features were extracted.Five-fold cross validation was used to divide the data into training set and test set,then the optimal brain functional network features related to postoperative outcomes of DR-mTLE patients were selected.Combining with clinically relevant independent predictors,ML models were constructed using classifiers including Gaussian process(GP),logistic regression(LR),support vector machine(SVM)and quadratic discriminant analysis(QDA),respectively,and the prediction efficacy,calibration and clinical value of each ML model were evaluated.Results Both course of disease and lesion location were clinically relevant independent predictors of postoperative outcome of DR-mTLE patients(OR=0.928,5.710,P=0.010,0.016).Four optimal brain function network features were selected,including betweenness centrality of the third zone of cerebellar vermis,degree centrality of right globus pallidus,nodal efficiency of temporal left inferior temporal gyrus and nodal clustering coefficient of left inferior parietal lobule.The average area under the curve(AUC)of GP,LR,SVM and QDA models in test set was 0.868,0.864,0.875 and 0.870,respectively.Calibration curves and decision curve analysis indicated that each ML model had good calibration and high clinical net benefit.Conclusion ML models based on brain functional network features combining with clinical indicators could be used to effectively predict postoperative outcomes in DR-mTLE patients.

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.
