Portal vein embolization （PVE） can induce atrophy of the embolized lobe and compensatory regeneration of the non-embolized lobe. However， due to inadequate regeneration of future liver remnant （FLR） after PVE， some patients remain unsuitable for hepatectomy after PVE. In recent years， liver venous deprivation （LVD）， which combines PVE with hepatic vein embolization （HVE）， has induced enhanced FLR regeneration. Compared with associating liver partition and portal vein ligation for staged hepatectomy （ALPPS）， LVD triggers faster and more robust FLR regeneration， with lower incidence rate of postoperative complications and mortality rate. By reviewing related articles on LVD， this article introduces the effectiveness of LVD and analyzes the differences and safety of various technical paths， and it is believed that LVD is a safe and effective preoperative pretreatment method.

Acute high-altitude (HA) illnesses (AHAIs), including acute mountain sickness (AMS), HA cerebral edema (HACE), and HA pulmonary edema (HAPE), represent significant health challenges for individuals rapidly ascending to high altitudes. Cytokines (interleukins (ILs)) and chemokines, which are involved in inflammatory and immunological responses, regulate the response of the body to hypoxic stress. Their dysregulation can contribute to the clinical symptoms of AMS, HACE, and HAPE by increasing vascular permeability, causing edema and damaging tissue. AHAIs elevate the levels of pro-inflammatory cytokines and chemokines, such as IL-17, tumor necrosis factor α (TNF-α), IL-1, IL-6, C-X-C motif chemokine ligand (CXCL) 10, CXCL8, C-C motif ligand 2 (CCL2 (CCL2), and CCL3, exacerbating symptoms. Thus, this review focuses on the cytokines and chemokines involved in AHAIs and the molecular mechanisms that extend beyond these cytokines and chemokines in clinical and preclinical contexts. Identifying these mediators and pathways helps researchers design drugs that reduce symptoms, slow disease progression, and enhance outcomes. Cytokines and chemokines have complex functions in these disorders and may serve as prospective therapeutic targets. Finally, we discuss treatment possibilities for AHAIs (drugs, exercise, and other inhibitors). This knowledge will help us to protect and improve the health of individuals at high altitudes.

OBJECTIVE: To investigate the predictive value of early lactate/albumin ratio (LAR) combined with quick sequential organ failure assessment (qSOFA) for the 28-day prognosis of patients with sepsis caused by emergency community-acquired pneumonia (CAP). METHODS: The clinical data of patients with sepsis caused by CAP admitted to the department of emergency of Beijing Haidian Hospital from June 2021 to August 2022 were retrospectively analyzed, including gender, age, comorbidities, lactic acid (Lac), serum albumin (Alb), LAR, procalcitonin (PCT) within 1 hour, and 28-day prognosis. Patients were divided into two groups based on 28-day prognosis, and risk factors affecting patients' prognosis were analyzed using univariate and multivariate Cox regression methods. Patients were divided into two groups according to the best cut-off value of LAR, and Kaplan-Meier survival curves were used to analyze the 28-day cumulative survival of patients in each group. Time-dependent receiver operator characteristic curve (ROC curve) were plotted to analyze the predictive value of sequential organ failure assessment (SOFA), acute physiology and chronic health evaluation II (APACHE II), and qSOFA+LAR score on the prognosis of patients with sepsis caused by CAP at 28 days. The area under the curve (AUC) was calculated and compared. RESULTS: A total of 116 patients with sepsis caused by CAP were included, of whom 80 survived at 28 days and 36 died, 28-day mortality of 31.0%. There were no statistically significant differences in age, gender, comorbidities, pH, platelet count, and fibrinogen between the survival and death groups, and there were significantly differences in blood urea nitrogen (BUN), white blood cell count (WBC), hemoglobin, Lac, Alb, PCT, D-dimer, LAR, as well as qSOFA score, SOFA score, and APACHE II score. Univariate Cox regression analyses showed that BUN, WBC, pH, Lac, Alb, PCT, LAR, qSOFA score, SOFA score, and APACHE II score were associated with mortality outcome. Multifactorial Cox regression analysis of the above variables showed that BUN, WBC, PCT, and APACHE II score were independent risk factors for 28-day death in the emergency department in patients with sepsis caused by CAP [hazard ratio (HR) were 1.081, 0.892, 1.034, and 1.135, respectively, all P < 0.05]. The best cut-off value of early LAR for predicting the 28-day prognosis of sepsis patients was 0.088, the Kaplan-Meier survival curve showed that the 28-day cumulative survival rate of sepsis patients in the LAR ≤ 0.088 group was significantly higher than that in the LAR > 0.088 group [82.9% (63/76) vs. 42.5% (17/40), Log-Rank test: χ² = 22.51, P < 0.001]. The qSOFA+LAR score was calculated based on the LAR cut-off value and qSOFA score, and ROC curve analysis showed that the AUCs of SOFA score, APACHE II score, and qSOFA+LAR score for predicting 28-day death of patients with sepsis caued by CAP were 0.741, 0.774, and 0.709, respectively, with the AUC of qSOFA+LAR score slightly lower than those of SOFA score and APACHE II score, but there were no significantly differences. When the best cut-off value of qSOFA+LAR score was 1, the sensitivity was 63.9% and the specificity was 80.0%. CONCLUSION The qSOFA+LAR score has predictive value for the 28-day prognosis of patients with sepsis caused by CAP in the emergency department, its predictive value is comparable to the SOFA score and the APACHE II score, and it is more convenient for early use in the emergency department.

Objective:To assess the prevalence of exercise addiction among college students and explore its relationship with negative emotion and exercise frequency.Methods:A total of 837 college students were enrolled from January 1, 2022 to December 31, 2022. The cross-sectional survey was administered using the exercise dependence scale revised(EDS-R) and the depression, anxiety, and stress scale 21 items (DASS-21). Data analysis was conducted with SPSS 26.0 software, including partial correlation analysis and hierarchical regression.Results:Among college students, the students in the group with risk and symptoms of exercise addiction accounted for 4.9%(EDS-R score (110.32±11.51), DASS-21-depression score 21.00(10.50, 25.00), DASS-21-anxiety score 21.00(11.50, 24.00), DASS-21-stress score 42.00(22.00, 47.50)). The students in the group without risk but with symptoms accounted for 42.53%(EDS-R score (60.02±12.91), DASS-21-depression score 8.00(1.00, 14.00), DASS-21-anxiety score 8.00(3.00, 14.00), DASS-21-stress score 15.00(4.00, 28.00)), and the students in the group without risk and symptoms accounted for 52.57%(EDS-R score (31.57±7.51), DASS-21-depression score 8.00(5.00, 12.00), DASS-21-anxiety score 7.00(3.00, 10.00), DASS-21-stress score 15.00(6.00, 21.00)). Exercise addiction scores were positively correlated with stress ( r=0.303, P<0.001), anxiety ( r=0.327, P<0.001), and depression ( r=0.259, P<0.001). The results of the hierarchical regression analysis also showed that the main risk variables were anxiety (△ R2=0.175, F=60.954) and exercise frequency (△ R2=0.044, F=21.401). Additionally, male college students had a higher risk of exercise addiction than female( P<0.01), but there was no gender difference in negative emotions( P>0.05). Conclusion:The college students were susceptible to developing an exercise addiction, especially among individuals with high exercise frequency and anxiety symptoms.It provides robust behavioral evidence in support of early detection and treatment of high-risk exercise addiction groups.

The increasing operating pressure of large public hospitals has forced hospitals to focus on opening up income sources and reducing expenditure.The purchase and maintenance of medical equipment is one of the important economic activities of hospi-tals.However,there are problems in large public hospitals,such as the argumentation for equipment acquisition ignoring evaluation of operational efficiency,the costing model that leads to a lack of willingness of departments to purchase equipment,and the lack of standard processes and systems for renting medical equipment among departments.Based on this,it explores the establishment of a medical equipment sharing operation mechanism in large public hospitals,promotes the improvement of the efficiency of medical equipment use in large public hospitals by establishing a medical equipment sharing center,standardizing the purchase of shared equipment,entering shared equipment information,setting up shared equipment leasing specifications,and clarifying the equipment return process and maintenance,so as to effectively control hospital operating costs,and help the high-quality development of public hospitals.

Circulating tumor cells(CTCs)are cells that dissociate from the tumor tissue and enter the lymphatic system or bloodstream with close association with tumor metastasis and recurrence.CTCs contain complete pathological information,which can be extracted by isolation,enrichment,and analysis of the CTCs to guide cancer diagnosis and treatment,thereby significantly improving the monitoring efficiency and prognosis of cancer.Compared with tissue biopsy,liquid biopsy with CTCs as a biomarker enables specific and dynamic detection of tumor growth with a less painful experience.For detection of CTCs,the cells must be captured from body fluids,followed then by their release and enrichment.This review summaries the latest research progress in responsive isolation of CTCs(e.g.with light,dielectrophoresis,acoustophoresis and magnetophoresis),chemical isolation(specific molecules and topological structure)and responsive release(e.g.,light,electric,thermal,pH,enzyme responsiveness,and substrates break).Responsive isolation utilizes the differences in physical properties between CTCs and blood cells,while chemical isolation utilizes specific recognition mechanisms to capture the CTCs.These techniques result in low cell damage with a high specificity to facilitate further analysis.Currently,CTC detection has been applied for early diagnosis and prognostic assessment of multiple cancers including lung cancer,liver cancer,colorectal cancer,and prostate cancer.
