Background/Aims: Liver transplantation (LT) following total hepatectomy is a life-saving treatment for hepatocellular carcinoma (HCC). The HCC recurrence after LT hinders the effectiveness of the procedure. The objective of this study is to develop a pre-operative risk stratification model based on a liquid biopsy. Methods: We conducted a comprehensive multi-omics study of 260 HCC patients from three centers, including clinical data, low-coverage whole-genome sequencing of cell-free DNA (cfDNA) from plasma, as well as whole-exome, single-nucleus RNA, and spatial transcriptomics from matched tumor and non-tumor tissues. Results: We identified cfDNA-derived copy number alteration (CNA) signatures associated with post-transplant recurrence. By integrating cfDNA-derived CNA profiles with single-cell transcriptomic data, we traced recurrence-associated cfDNA to a distinct subpopulation of malignant cells within the primary tumor. These cells were embedded in a pro-metastatic microenvironment of specialized endothelial subtypes and cancer-associated fibroblasts. Notably, most recurrence-associated lesions were detectable in cfDNA prior to liver transplantation (LT). Building on these insights, we developed the ZJU Criteria based on CNA fragments and tumor markers, a pre-LT risk prediction tool that integrates conventional clinical factors with cfDNA-derived CNA signatures, and validated it using internal and independent external cohorts. Conclusion Our findings suggest that post-transplant recurrence commonly originates from advanced subclones that emerge late during tumor evolution. The ZJU Criteria provides an accurate, non-invasive strategy that significantly improves pre-LT risk stratification and clinical decision-making for patients with HCC.

Objective:To investigate the clinical manifestations，etiology/triggers，treatment，and prognosis of children with cerebral venous sinus thrombosis（CVST）.Methods:A retrospective analysis was conducted on 36 children with CVST hospitalized at the Affiliated Children's Hospital of Xiangya School of Medicine,Central South University（Hunan Children's Hospital）from May 2014 to January 2024.A centralized telephone follow-up was performed in May 2024，and clinical data including symptoms，imaging findings，treatments，and outcomes were collected.According to the prognosis,the children were divided into favorable-prognosis group and poor-prognosis group,and the differences of clinical characteristics between the two groups were compared.The univariate Logistic regression was applied to identify factors associated with prognosis.Results:Among the 36 cases,there were 29 males and 7 females,ranging in age from 1 month to 13 years and 3 months,with a median age of 4.6(1.0,8.3) years.The common clinical manifestations included headache（24/25，96.0%），consciousness disorder（25/36，69.4%），vomiting（22/36，61.1%），seizures（14/36，38.9%），limb dysfunction（11/36，30.6%）.The leading etiologies were infection（14/36，38.9%），head trauma（8/36，22.2%），and tumors/chemotherapy（6/36，16.7%）.All 36 children underwent MRI+MRV examination of the head,and all of them had different degrees of CVST,the most commonly involved site was transverse sinus (28/36,77.8%).The favorable-prognosis group（ n=18）included 16 patients receiving anticoagulation and 2 trauma cases without anticoagulation.The poor-prognosis group（ n=18）comprised 9 anticoagulated and 9 non-anticoagulated patients.There were no significant differences in age,sex,clinical manifestations,etiology/inducement and thrombus site between the two groups ( P>0.05).However,the proportion of anticoagulant therapy in the favorable-prognosis group was higher than that in the poor-prognosis group(88.9% vs 50.0%).Among the 25 children receiving anticoagulant therapy,16 had a good prognosis (64.0%),while among the 11 children receiving no anticoagulant therapy,only 2 had a good prognosis (18.2%).The prognosis of children receiving anticoagulant therapy was better than that of those receiving no anticoagulant therapy.The difference was statistically significant ( P<0.05).Fourteen children were admitted with intracranial hemorrhage,with 8 receiving anticoagulant therapy (7 with good prognosis,accounting for 87.5%) and 6 not receiving anticoagulant therapy (only 1 with good prognosis,accounting for 12.5%).The prognosis of children receiving anticoagulant therapy was better than that of those receiving no anticoagulant therapy,and the difference was statistically significant ( P=0.026),with no increasing in intracranial hemorrhage after anticoagulant therapy.Univariate Logistic regression analysis showed that inducement/etiology,intracranial hemorrhage before treatment and prognosis were not related（ P >0.05），but anticoagulation treatment was associated with favorable outcomes（ OR=0.125，95% CI 0.017-0.614, P=0.009）. Conclusion:Infection is the primary etiology of pediatric CVST，with headache，lethargy，and vomiting as key symptoms.Transverse sinus is the most commonly involved site.Children suspected of CVST should be examined by MRI/MRV as soon as possible,and early anticoagulation therapy should be given after a clear diagnosis,so as to improve the prognosis.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

BACKGROUND:The level of peripheral erythrocytes in rats is significantly increased under hypoxia exposure,and the proliferation of nucleated erythrocytes in the bone marrow may be one of the direct causes of the increase in peripheral erythrocytes.Previous studies have focused on the effects of factors such as erythropoietin and hypoxia-inducible factor,but little research has been done on related factors such as inflammation and immunity.OBJECTIVE:To study the expression of interleukin-18 in bone marrow nucleated erythrocytes,bone marrow supernatant and peripheral blood of rats after hypoxia exposure,and to explore the possible role of interleukin-18 in the pathogenesis of chronic mountain sickness.METHODS:Sixteen healthy male SD rats were randomly divided into two groups:the experimental group was kept in a hypobaric oxygen chamber at a simulated altitude of 5 000 m for 28 days,and the control group was kept in a laboratory at an altitude of 2 260 m for 28 days.The blood routine tests of the two groups of rats were performed.The proportion of CD71+nucleated erythrocytes in the bone marrow of the two groups of rats was determined by flow cytometry.The expressions of interleukin 18 mRNA and protein in CD71+nucleated erythrocytes in the bone marrow of the two groups of rats were determined by RT-qPCR and western blot assay.The expressions of interleukin 18 protein in the sternum of the two groups of rats were determined by immunofluorescence.The levels of interleukin 18 in the peripheral blood and bone marrow supernatant of the two groups of rats were determined by ELISA.RESULTS AND CONCLUSION:(1)The indexes of erythrocyte count,hemoglobin,hematocrit,and mean hemoglobin content in peripheral blood of the experimental group were higher than those of the control group(P＜0.05).(2)The proportion in bone marrow CD71+erythroblasts was significantly higher in the experimental group than that in the control group(P＜0.05).(3)RT-qPCR results showed that the expression of interleukin 18 mRNA in CD71+nucleated erythrocytes in the bone marrow of rats in the experimental group was significantly higher than that in the control group(P＜0.05).(4)Western blot assay results showed that the expression of interleukin 18 protein in CD71+nucleated erythrocytes in the bone marrow of rats in the experimental group was significantly higher than that in the control group(P＜0.05).(5)The immunofluorescence results showed that the expression of interleukin 18 protein in the sternum of rats in the experimental group was significantly higher than that in the control group(P＜0.05).(6)ELISA results exhibited that the level of interleukin 18 in the serum of rats of the experimental group was higher than that in the control group(P＜0.05),but the level of interleukin 18 in the bone marrow supernatant of rats in the experimental group was lower than that in the control group(P＜0.05).The results indicate that the increased expression of interleukin 18 in bone marrow CD71+erythroblasts and peripheral blood of rats under hypobaric hypoxia may be involved in the proliferation of erythroblasts in bone marrow.

Objective To explore the incidence rate and independent risk factors of synchronous multiple early gastric cancer (SMEGC) in patients with early gastric cancer, and to provide evidence for early screening and intervention of high-risk population. Methods A retrospective analysis was performed on 308 patients with early gastric cancer who received treatment in the hospital from March 2019 to March 2024. The incidence rate of SMEGC was counted, and the risk factors were analyzed by univariate and multivariate Logistic regression analyses. Results Among the 308 patients with early gastric cancer in this study, 23 cases were SMEGC and 285 were single early gastric cancer, which were included in the SMEGC group and the single group respectively. The incidence rate of SMEGC was 7.47% (23/308). Compared with the single group, the proportions of male, smoking history, tumor diameter≤2 mm, chronic atrophic gastritis and intestinal metaplasia degree were higher in the SMEGC group (2=4.331、8.608、4.618、6.490、4.897，P=0.037、0.003、0.032、0.001、0.027). Logistic regression analysis suggested that chronic atrophic gastritis (OR=3.133, 95%CI: 1.240-7.918) and moderate-to-severe intestinal metaplasia (OR=3.171, 95%CI: 1.252-8.029) were independent risk factors for SMEGC (P<0.05). Conclusion Some patients with early gastric cancer are SMEGC. Chronic atrophic gastritis and moderate-to-severe intestinal metaplasia are independent risk factors affecting the occurrence of SMEGC. It is recommended to regularly screen high-risk patients and optimize management strategies to reduce the risk of SMEGC.

Objective To propose a high-precision deep learning-based image assessment method of osteosarcoma chemotherapy efficacy for clinical treatment,as existing methos have low accuracy of osteosarcoma assessment.Methods The low incidence of osteosarcoma led to the small scale of its imaging data and the problem of imbalance in data categories.This study combined deep learning with clinical medical information,combined the bone sarcoma generation module of BoneGAN and the scale lesion information capture module,and proposed OMLA-Net,a deep learning assessment network for chemotherapy effect of bone sarcoma based on multi-scale lesion attention network,which achieved computer-aided bone tumor assessment with integrated data augmentation and focused lesion information through pre-training and generalized loss training.Results In this study,40 cases of osteosarcoma MRI data were used as the basis for the comparison test on the generated dataset,and the OMLA-Net assessment outperformed the SOTA method Conv-LSTM-GAN in terms of the assessment effects such as accuracy and F1 scores,and the difference was statistically significant(Bootstrap statistical method P＜0.05);the subsequent K-fold cross-validation ablation experiments further demonstrated the effectiveness of each module proposed by OMLA-Net.Conclusion OMLA-Net can effectively perform the impact assessment of chemotherapy effect on osteosarcoma,which provides a new idea for subsequent clinical application.

BACKGROUND: Modern acupuncture anesthesia is a combination of Chinese and Western medicine that integrates the theories of acupuncture with anesthesia. However, some clinical studies of acupuncture anesthesia lack specific descriptions of randomization, allocation concealment, and blinding processes, with subsequent systematic reviews indicating a risk of bias. OBJECTIVE: Clinical trial registration is essential for the enhancement of the quality of clinical trials. This study aims to summarize the status of clinical trial registrations for acupuncture anesthesia listed on the World Health Organization International Clinical Trials Registry Platform (ICTRP). SEARCH STRATEGY: We searched the ICTRP for clinical trials related to acupuncture anesthesia registered between January 1, 2001 and May 31, 2023. Additionally, related publications were retrieved from PubMed, Cochrane Library, Embase, China National Knowledge Infrastructure, China Science and Technology Journal Database, and Wanfang Data. Registrations and publications were analyzed for consistency in trial design characteristics. INCLUSION CRITERIA: Clinical trials that utilized one of several acupuncture-related therapies in combination with pharmacological anesthesia during the perioperative period were eligible for this review. DATA EXTRACTION AND ANALYSIS: Data extracted from articles included type of surgical procedure, perioperative symptoms, study methodology, type of intervention, trial recruitment information, and publication information related to clinical enrollment. RESULTS: A total of 166 trials related to acupuncture anesthesia from 21 countries were included in the analysis. The commonly reported symptoms in the included studies were postoperative nausea and vomiting (19.9%) and postoperative pain (13.3%). The concordance between the publications and the trial protocols in the clinical registry records was poor, with only 31.7% of the studies being fully compatible. Inconsistency rates were high for sample size (39.0%, 16/41), blinding (36.6%, 15/41), and secondary outcome indicators (24.4%, 10/41). CONCLUSION The volume of acupuncture anesthesia clinical trials registered in international trial registries over the last 20 years is low, with insufficient disclosure of results. Postoperative nausea and vomiting as well as postoperative pain, are the most investigated for acupuncture intervention.

OBJECTIVE: This study reports the first imported case of Lassa fever (LF) in China. Laboratory detection and molecular epidemiological analysis of the Lassa virus (LASV) from this case offer valuable insights for the prevention and control of LF. METHODS: Samples of cerebrospinal fluid (CSF), blood, urine, saliva, and environmental materials were collected from the patient and their close contacts for LASV nucleotide detection. Whole-genome sequencing was performed on positive samples to analyze the genetic characteristics of the virus. RESULTS: LASV was detected in the patient's CSF, blood, and urine, while all samples from close contacts and the environment tested negative. The virus belongs to the lineage IV strain and shares the highest homology with strains from Sierra Leone. The variability in the glycoprotein complex (GPC) among different strains ranged from 3.9% to 15.1%, higher than previously reported for the seven known lineages. Amino acid mutation analysis revealed multiple mutations within the GPC immunogenic epitopes, increasing strain diversity and potentially impacting immune response. CONCLUSION The case was confirmed through nucleotide detection, with no evidence of secondary transmission or viral spread. The LASV strain identified belongs to lineage IV, with broader GPC variability than previously reported. Mutations in the immune-related sites of GPC may affect immune responses, necessitating heightened vigilance regarding the virus.

OBJECTIVE: This study aimed to evaluate the relationships of white blood cell (WBC) count, platelet (PLT) count, and PLT-to-WBC ratio (PWR) with muscle mass in Chinese older adults. METHODS: This cross-sectional analysis involved 4,033 Chinese older adults aged ≥ 65 years from the Healthy Ageing and Biomarkers Cohort Study. Muscle mass and total skeletal muscle mass index (TSMI) were measured by bioelectric impedance analysis. WBC, PLT, and PWR were measured using standard methods. Multivariate linear regression was used to examine the associations of WBC count, PLT count, and PWR with TSMI. RESULTS: High WBC count, PLT count, and PWR were associated with low TSMI, with coefficients of -0.0091 (95% confidence interval [ CI]: -0.0142 to -0.0041), -0.0119 (95% CI: -0.0170 to -0.0068), and -0.0051 (95% CI: -0.0102 to -0.0001). The associations between the three inflammatory indices and TSMI were linear. Stratified analyses indicated that the relationship between inflammatory markers and TSMI was more evident in male participants and in individuals aged < 80 years than in their counterparts. CONCLUSION Elevated WBC count, PLT count, and PWR correlated with muscle mass loss. This study highlights the importance of regular monitoring of inflammatory markers as a potential strategy for the screening and management of sarcopenia in older adults.
