BACKGROUND: Meningeal metastasis (MM) is a form of malignant metastasis where tumor cells spread from the primary site to the pia mater, dura mater, arachnoid, subarachnoid space, and other cerebrospinal fluid compartments. Lung cancer is one of the most common malignant tumor types with MM. MM not only signifies that the lung cancer has progressed to an advanced stage but also leads to a range of severe clinical symptoms due to meningeal involvement. Currently, the risk factors associated with the development of MM are not fully elucidated. The aim of this study was to investigate the risk factors for MM in patients with lung adenocarcinoma (LUAD) who underwent non-surgical interventions, in order to identify LUAD patients at high risk for MM. METHODS: This retrospective study analyzed the clinical data of patients diagnosed with LUAD at the First Affiliated Hospital of Zhengzhou University from January 2020 to July 2024. Missing data were imputed using multiple imputation methods, and risk factors were identified through LASSO, univariate, and multivariate Logistic regression analyses. RESULTS: A total of 170 patients with LUAD were included in this study and divided into two groups: 87 patients with MM and 83 patients without MM. Univariate and multivariate Logistic regression analyses revealed that younger age at diagnosis (P=0.004), presence of the epidermal growth factor receptor (EGFR) L858R gene mutation (P=0.008), and concurrent liver metastasis at baseline (P=0.004) were independent risk factors for developing MM in LUAD patients who did not undergo surgical intervention. Conversely, higher baseline globulin levels (P=0.039) and the presence of the anaplastic lymphoma kinase (ALK) gene mutation (P=0.040) were associated with a reduced risk of MM development. CONCLUSIONS Age at diagnosis, EGFR L858R mutation status, ALK gene mutation status, concurrent liver metastasis, globulin levels at baseline were significantly associated with the risk of developing MM in patients with LUAD patients who did not undergo surgical intervention. For patients diagnosed at a younger age, carrying the EGFR L858R mutation, or presenting with baseline liver metastasis, early implementation of tertiary prevention strategies for MM is crucial. Regular monitoring of MM status should be conducted in these high-risk groups.

Liver transplantation remains the most effective treatment for end-stage liver disease(ESLD),but it is fraught with challenges such as immunosuppression,high risk and cost,and donor shortage.In recent years,stem cell transplantation has emerged as a promising new strategy for ESLD treatment,with mesenchymal stem cells(MSCs)gaining significant attention because of their unique properties.MSCs can regulate signaling pathways,including hepatocyte growth factor/c-Met,Wnt/beta(β)-catenin,Notch,transforming growth factor-β1/Smad,interleukin-6/Janus kinase/signal transducer and activator of transcription 3,and phosphatidylinositol 3-kinase/PDK/Akt,thereby influencing the progression of liver fibrosis and regeneration.As a promising stem cell type,MSCs offer numerous advantages in liver disease treatment,including low immunogenicity;ease of acquisition;unlimited proliferative ability;pluripotent differentiation potential;immunomodulatory function;and anti-inflammatory,antifibrotic,and anti-apoptotic biological characteristics.This review outlines the mechanisms by which MSCs reverse liver fibrosis and promote liver regeneration.MSCs are crucial in reversing liver fibrosis and repairing liver damage through the secretion of growth factors,regulation of signaling pathways,and modulation of immune responses.MSCs have shown good therapeutic effects in preclinical and clinical studies,providing new strategies for liver disease treatment.However,challenges still exist in the clinical application of MSCs,including low differentiation efficiency and limited sources.This review provides a reference for MSC application in liver disease treatment.With the continuous progress in MSC research,MSCs are expected to achieve breakthroughs in liver disease treatment,thereby improving patient treatment outcomes.

The technology of split liver transplantation is becoming increasingly mature with rapid development. During ex vivo splitting, the depletion of intracellular energy sources [such as adenosine triphosphate (ATP)] and other metabolic disorders may lead to cell damage and dysfunction, which will be aggravated by reperfusion injury of liver transplantation, clinically manifested as postoperative complications and transplantation failure. To further improve the quality of donor liver in ex vivo split liver transplantation, research teams at home and abroad apply machine perfusion to enhance the quality of donor liver. In this article, the research progresses worldwide on machine perfusion of donor liver in ex vivo split liver transplantation were reviewed, and the application and prospect of dual hypothermic oxygenated machine perfusion (D-HOPE) in ex vivo split liver transplantation were elucidated, aiming to provide reference for increasing the source of donor liver for ex vivo split liver transplantation and further resolving the current status of donorliver shortage.

Objective:To perform trans-peritoneal laparoscopic adrenalectomy via a single incision in treatment of adrenal tumors,and to discuss its clinical outcome and safety.Methods:Single incision trans-peritoneal laparoscopic adrenalectomy was used in treatment of three patients with adrenal tumors.The incision was made 3 cm below the costal margin of anterior axillary line; three Tocars were placed in the cut.The instruments used included single port access,CUSA,Hem-o-lok,etc..Results:The three operations were all successful,and there were no conversion to open procedure or a need for extra Ttrocars.The operating time periods were 75,116,and 135 min,with a mean of (108.7?30.7)min.The perioperative blood losses were 10,20,and 30 ml,with a mean of (20?10)ml.The gastric canal and ureteral catheter were withdrew one day after operation,and the drainage tube was withdrew 3 d after operation.The mean postoperative hospital stay was 4 d.Conclusion:Single incision trans-peritoneal laparoscopic adrenalectomy has the advantage of little trauma,less blood loss,satisfactory safety,and prompt postoperative recovery,but is difficult to manage.
