Objective To explore the prevalence of depressive symptoms in postoperative patients with ovarian cancer and to analyze its influencing factors from multiple dimensions, including clinical characteristics, psychological factors, and laboratory indicators. Methods A cross-sectional study was conducted, which enrolled 235 postoperative patients with ovarian cancer. Depressive status was assessed using the patient health questionnaire, and the demographic, pathological, and medical record data of the patients were collected using the generalized anxiety disorder scale, Pittsburgh sleep quality index, European organization for research and treatment of cancer quality of life questionnaire core 30, and ECOG performance status score. Peripheral blood tumor marker (CA125), routine blood test, lymphocyte subsets, and serum cytokine levels were measured. Univariate and multivariate binary logistic regression analysis were used for statistical analysis. Results The prevalence of depression in postoperative patients with ovarian cancer was 39.15% (92/235). Univariate analysis showed that ECOG score ≥ 2 points, pain, anxiety, poor sleep quality, low quality of life, low life satisfaction, tumor recurrence, six or more cycles of chemotherapy, as well as higher levels of CA125, NLR, and NAR, and lower hemoglobin levels were significantly associated with depression (all P<0.05). Multivariate binary Logistic regression analysis showed that anxiety (OR=1.975, 95%CI: 1.231-3.170), sleep efficiency (OR=4.181, 95%CI: 1.211-14.43), sleep latency (OR=34.806, 95%CI: 4.258-284.542), ECOG performance status score, cognitive function (OR=0.918, 95%CI: 0.868-0.97), and life satisfaction were independent risk factors for depression (all P<0.05). Laboratory indicators were not independent influencing factors in the multivariate Logistic regression model. Conclusion Depression in postoperative patients with ovarian cancer is influenced by physiological, psychological, and social factors. Clinical management should focus on patients with anxiety, sleep disorders, poor physical condition, and low life satisfaction, and a comprehensive prevention and treatment strategy centered on psychological intervention and taking into account symptom management and social support should be implemented.

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.

Immunotherapy for cancer,as an emerging treatment modality,has made significant strides in recent years and has become a crucial therapeutic approach following surgery,radiotherapy,chemotherapy,and targeted therapy.In particular,the clinical utilization of immune checkpoint inhibitors(ICIs)has not only enhanced the survival rates of patients with refractory or recurrent tumors but has also significantly optimized the overall strategy for cancer treatment.However,as the population undergoing cancer immunotherapy continues to grow,this expansion not only yields clinical benefits but also precipitates a range of specific adverse reactions known as immune-related adverse events(irAEs).Pleural effusion is a common and severe complication in cancer patients,significantly affecting both their quality of life and treatment outcomes.Typically,tumor-related pleural effusion is often due to pleural metastasis,with malignant pleural effusion(MPE)characterized by rapid growth,being difficult to control,and tendency for recurrence.With the approval of new drugs and the expansion of indications for existing medications,the number of cancer patients receiving ICIs treatment is increasing,bringing ICIs-related pleural effusion into focus.While ICIs treatment-related pleural effusion is relatively rare in clinical practice,it is closely linked to treatment choices of patients and prognosis.Unlike MPE,the pathogenesis of ICIs treatment-related pleural effusion is more complex,not only involving non-specific immune activation leading to autoimmune inflammatory reactions but also potentially related to nodular pleural granulomatous reactions,eosinophilic chronic pleurisy,and tumor-infiltrating lymphocytes.In terms of diagnosis,ICIs treatment-related pleural effusion is typically diagnosed through exclusion,requiring the exclusion of other causes such as tumor progression,radiotherapy,and chemotherapy-induced pleural effusion,adding complexity and difficulty to the diagnostic process.Treatment for ICIs treatment-related pleural effusion often involves glucocorticoids,tocilizumab,or infliximab,aiming to alleviate symptoms and improve prognosis by suppressing excessive immune reactions.Preventing the occurrence of ICIs treatment-related pleural effusion is equally crucial,necessitating comprehensive patient assessment before ICIs administration and continuous monitoring during treatment to promptly detect and manage potential adverse reactions.Through this comprehensive management approach,the impact of ICIs treatment-related pleural effusion on patient quality of life and treatment outcomes can be minimized,optimizing overall treatment results.This review aimed to explore the pathogenesis,histological features,clinical manifestations,diagnostic methods and treatment strategies of ICIs treatment-related pleural effusion,and delve into the characteristics of ICIs treatment-related pleural effusion,in order to enhance understanding of this complication and provide a reference for clinical practice.

Objective:To explore the application value of the "Dual-Wing" traction technique in the medial & head lateral laparoscopic left hemicolectomy with radical resection.Methods:The "Dual-Wing " traction technique is based on the theory of mesenteric anatomy. The assistant lifts the proper mesentery of the digestive tract to be resected or the adjacent mesenteric tissue connected to it,thereby elevating the target organ and its mesentery as a whole away from the mesenteric bed. By utilizing the tension transmission between the proper mesenteries of adjacent organs to create counter-tension,the surgeon's operative actions are always maintained along the line of maximum counter-tension.After incising the mesenteric fusion line,this technique assists the surgeon in entering the fusion plane. A descriptive case series study method was adopted to retrospectively analyze the clinical and pathological data of 37 colorectal cancer patients who underwent laparoscopic left hemicolectomy with the "Dual-Wing" traction technique via a medial and cephalad approach, performed by the Department of Gastrointestinal Surgery at Dongjie Campus of the First Hospital of Quanzhou, Fujian Medical University, from May 2023 to November 2023.Results:All patients successfully underwent laparoscopic left hemicolectomy via the medial & head lateral approach using the "Dual-Wing" traction technique.The surgery adhered to the principles of total mesocolic excision and safely mobilized the left colon and its mesentery from the correct anatomical plane. In the entire group of patients,there were 14 males and 23 females; the mean operative time was 94.1±18.3 minutes; the mean intraoperative blood loss was 9.8±5.4 ml; the mean number of lymph nodes dissected was 18.1±3.9; the mean number of positive lymph nodes was 1.4±1.6; the pathological specimen resection margin grading was Grade A in 29 cases, Grade B in 8 cases, and no Grade C cases; the tumor TNM staging was Stage I in 3 cases, Stage IIA in 7 cases, Stage IIB in 6 cases, Stage IIIA in 2 cases, Stage IIIB in 15 cases, and Stage IIIC in 4 cases; the mean time to first flatus postoperatively was 35.7±7.5 hours; the mean length of hospital stay was 9.1±1.7 days. There were no intraoperative injuries to the pancreas or spleen. Postoperative complications occurred in 3 cases. No anastomotic leakage was observed in the entire group, and there were no deaths following the surgery.Conclusion:The application of the "Dual-Wing" traction technique to establish a stable surgical scenario can significantly reduce the demands on the assistant. It is conducive to maintaining mesenteric tension and fully exposing the surgical field. It also allows for the rapid identification and maintenance of the correct anatomical plane. For colorectal cancer patients, the surgery is safe and feasible, with satisfactory short-term therapeutic effects.

Objective:To analyze the association between healthcare workers mental health,institu-tional supplies and facilities,inter-organizational coordination during infectious disease outbreaks,and the healthcare institution resilience.Methods:An online questionnaire survey was conducted among the healthcare workforce from 146 institutions in Beijing from January 13,2023 to February 9,2023,and a total of 1 434 eligible respondents were included.The sample comprised 408 responses from tertiary hos-pitals,117 from secondary hospitals,and 909 from primary care institutions.The resilience indicator for healthcare institutions was defined as the degree to which medical services met patient demands,with in-fluencing factors including physical factors,such as material shortages and facility space adaptation or ex-pansion,organizational factors such as information sharing and patient referral,and psychological factors were evaluated using job satisfaction(extrinsic satisfaction,intrinsic satisfaction),burnout(emotional exhaustion,depersonalization,reduced personal accomplishment),and depression status.Ordered mul-ticlassification Logistic regression was used to examine the impact of various factors on the degree to which healthcare services met patient needs;additionally,demographic factors that might influence institutional resilience were controlled.Results:During the emergency response phase,93％of hospitals maintained the capacity to meet patient needs,though tertiary hospitals demonstrated significantly higher rates of service inadequacy(21.05％).Material shortages were reported across all institutions,with tertiary hos-pitals experiencing more frequent multi-item shortages.Inter-institutional collaboration patterns revealed substantial variation:87.50％of primary care facilities,42.86％of secondary hospitals,and 31.58％of tertiary hospitals.Healthcare workers across all levels reported mild depressive symptoms and moderate-to-severe burnout levels.Regression analysis showed high satisfaction(overall satisfaction β=0.04,ex-trinsic satisfaction β=0.06,and intrinsic satisfaction β=0.08),low degree of job burnout(emotional exhaustion β=-0.04,depersonalization β=-0.07 and reduced personal accomplishment β=0.01),low degree of depression(β=-0.06)were significantly associated with higher healthcare institution re-silience.In addition,material shortages were significantly associated with lower resilience,and renova-tion and expansion of treatment spaces,and information sharing,were all associated with higher resilience.Demographic factors(age,gender,marital status,educational background,etc.)had no sig-nificant impact on resilience.Conclusion:Mental health status significantly influences healthcare institu-tion resilience.As human resources constitute the core asset of healthcare institutions,strategic optimiza-tion of workforce allocation and psychological support interventions can effectively strengthen resilience.Moreover,healthcare institution resilience is positively impacted by orderly material supply chains,timely resource distribution,and adaptive reconfiguration of clinical spaces.Finally,facilitating information sharing also enhances institutional resilience.

Objective To investigate the function of the glutamic-oxaloacetic transaminase 2(GOT2)gene in acute myeloid leukemia cells.Methods ShRNAs targeting at GOT2 were constructed to suppress GOT2 expression in the THP-1 human monocytic leukemia cell line.GOT2 mRNA level was measured by RT-qPCR,and GOT2 protein ex-pression was measured by Western blot.Intracellular free amino acid level was quantified using colorimetric assays.The impact of GOT2 knockdown in THP-1 cell function was evaluated through cell viability(CCK-8 assay)and ap-optosis(flow cytometry).Results After GOT2 knockdown,both GOT2 mRNA and protein were significantly de-creased in THP-1 cells(P＜0.05).Compared to the control group,GOT2 knockdown did not affect intracellular glutamate levels(P＞0.05),but led to a marked decrease in aspartate level(P＜0.05).GOT2 knockdown signifi-cantly impaired THP-1 cell viability,inhibited cell proliferation(P＜0.05)and promoted apoptosis(P＜0.05).Conclusions Down regulation of GOT2 significantly decreases intracellular aspartate level in acute myeloid leukemia cells,impairs cellular viability and induces apoptosis,which suggests that GOT2 may play a key role in the regula-tion of amino acid metabolism in acute myeloid leukemia.
