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.

Psychological problems are significant factors that contribute to the occurrence of postoperative complications, reduced quality of life, and prolonged hospital stays. Lung cancer patients who require surgery often experience high psychological stress related to both the disease and the treatment, making them more susceptible to depression and anxiety. Therefore, timely intervention to address these psychological issues is crucial for promoting postoperative recovery and improving patients' quality of life. This paper will review the current status, impact, and interventions for depression and anxiety-related psychological problems in lung cancer surgery patients.

Multiple system atrophy (MSA) is a rare neurodegenerative disease with complex clinical manifestations, presenting substantial challenges in clinical diagnosis and treatment. Its symptoms and the eight extraordinary meridians are potentially correlated; therefore, this article explores the association between MSA symptom clusters and the eight extraordinary meridians based on their circulation and physiological functions, as well as their treatment strategies. The progression from deficiency to damage in the eight extraordinary meridians aligns with the core pathogenesis of MSA, which is characterized by "the continuous accumulation of impacts from the vital qi deficiency leading to eventual damage". Liver and kidney deficiency and the emptiness of the eight extraordinary meridians are required for the onset of MSA; the stagnation of qi deficiency and the gradual damage to the eight extraordinary meridians are the key stages in the prolonged progression of MSA. The disease often begins with the involvement of the yin and yang qiao mai, governor vessel, thoroughfare vessel, and conception vessel before progressing to multiple meridian involvements, ultimately affecting all eight extraordinary meridians simultaneously. The treatment approach emphasizes that "the direct method may be used for joining battle, but indirect method will be needed in order to secure victory" and focuses on "eliminate pathogenic factors and reinforce healthy qi". Distinguishing the extraordinary meridians and focusing on the primary symptoms are pivotal to improving efficacy. Clinical treatment is aimed at the target, and tailored treatment based on careful clinical observation ensures precision in targeting the disease using the eight extraordinary meridians as the framework and core symptoms as the specific focus. Additionally, combining acupuncture, daoyin therapy, and other method may help prolong survival. This article classifies clinical manifestations based on the theory of the eight extraordinary meridians and explores treatment.

In this paper， the name， origin， producing area， harvesting， processing and functional indications of Arcae Concha were systematically combed and verified by consulting the ancient and modern literature， in order to provide a basis for the development of famous classical formulas containing Arcae Concha. Arcae Concha was first recorded in the name of Han in Bencao Shiyi， but later， due to the influence of LI Shizhen's error of combining Han item with Kuiha in the Ming dynasty， there were aliases such as Kuilu and Fulao， and Yizong Bidu began to include Walengzi as its correct name and has been used ever since. The textual descriptions and illustrations of the medicinal materials of Arcae Concha contained in the materia medica of the past generations were consistent with the modern Arca inflata， A. subcrenata and A. granosa. In ancient times， there were medicinal records of two parts of shell and meat， but now the shell is used as medicine， and the meat is mostly edible. In ancient times， Zhejiang， Shandong， Guangdong and Guangxi were the main producing areas， and Zhejiang was the best. It is now believed that A. inflata is mostly distributed in the northern part of the Huanghai Sea， A. granosa is mostly distributed in the coastal areas south of Shandong Peninsula in China， and A. subcrenata is widely distributed in the coastal areas of China. Its quality is better in a complete， white， no residual meat and sand. In ancient times， there was no clear harvesting period， and the processing was mainly based on vinegar quenching after calcination or powdering of calcined shell， but now the harvesting period is autumn and winter. After harvesting， it is directly washed and crushed for raw use or processed by calcined method. The records of the medicinal materials in the past dynasties on the properties of Arcae Concha were mainly warm， sweet， salty and mild， and it is now believed that Arcae Concha is salty in taste and mild in nature. In ancient times， it was believed that Arcae Concha were mainly used for coldness in the heart and abdomen， coldness in the waist and spine， benefiting the five internal organs， strengthening the stomach. Nowadays， it is believed that Arcae Concha can eliminate phlegm and remove blood stasis， soften the hardness and dissipate the lumps， produce acid and relieve pain. It can be used in the treatment of stubborn phlegm， gall tumor， scrofula and other symptoms. In conclusion， it is suggested that for the famous classical formulas containing Arcae Concha， the corresponding methods should be selected according to the processing requirements of the drug in the formulas， while those without processing requirements can be determined according to the functional position of the products.

Objective To observe the repair effect and mechanism of Danhuang Powder-containing serum on high glucose-induced vascular endothelial cell injury.Methods Danhuang Powder-containing serum was prepared.Human umbilical vein endothelial cells(HUVECs)were cultured to be divided into control group,recombinant human epidermal growth factor(called"growth factor"for short)group,Danhuang Powder group,high glucose group,high glucose+growth factor group,and high glucose+Danhuang Powder group.After corresponding intervention in each group for 48 hours,the cell ultrastructure and autophagy were observed under transmission electron microscope,apoptosis was detected by flow cytometry,and the protein expression levels of vascular endothelial growth factor(VEGF),epidermal growth factor(EGF)and basic fibroblast growth factor(bFGF)in the cells were detected by Western Blot.Results(1)The intra-mitochondrial ridges in the control group were clearly visible,autophagosomes and autolysosomes were fewer;mitochondria in the high glucose group were swollen and irregular,and appeared vacuolated;and the more typical autophagy-like structures were seen in the high glucose+Danhuang Powder group.(2)Compared with the high glucose group and high glucose+growth factor group,the apoptosis rate of cells in the high glucose+Danhuang Powder group was significantly decreased(P<0.05).(3)Compared with the high glucose group and the high glucose+growth factor group,the protein expression levels of VEGF,EGF and bFGF in the cells of the high glucose+Danhuang Powder group were significantly increased(P<0.05).Conclusion Danhuang Powder-containing serum can reduce the high glucose-induced damage in HUVEC cells,and its mechanism may be related to the activation of mitochondrial autophagy,and the inhibition of apoptosis,as well as the up-regulation of the expression of VEGF,EGF and bFGF.

Objective To investigate the expression of forkhead box P3(Foxp3)in peripheral blood of children with bronchial asthma and its relationship with airway hyper-responsiveness and body allergy.Methods A total of 80 children with bronchial asthma treated in the Affiliated Hospital of Yangzhou University from July 2024 to June 2025 were selected as experimental group,and 47 health-y children with physical examinations in the same period were selected as control group.Airway hy-per-responsiveness indicators(respiratory resistance,bronchial stimulant reaction threshold,and re-sistance increase slope),body allergy indicators[serum immunoglobulin E(IgE),eosinophil cationic protein(ECP),and eosinophil count(EOS)],pulmonary function indicators[peak expiratory flow(PEF),forced expiratory volume in the first second(FEV,),forced vital capacity(FVC),and the ratio of forced expiratory volume in the first second to forced vital capacity(FEV1/FVC)],and the expression level of Foxp3 in peripheral blood were compared between the two groups.Pearson corre-lation analysis was used to explore the correlations of Foxp3 with airway hyper-responsiveness and body allergy.Results The respiratory resistance and resistance increase slope in the control group were significantly lower than those in the experimental group,while the reaction threshold was signif-icantly higher than that in the experimental group(P＜0.05).The levels of IgE,ECP and EOS in the experimental group were significantly higher than those in the control group(P＜0.05).The FEV1,FVC,PEF,and FEV1/FVC in the experimental group were significantly lower than those in the control group(P＜0.05).The expression level of Foxp3 in the experimental group was(3.04±0.22),which was significantly lower than(4.22±0.41)in the control group(P＜0.05).Foxp3 was significantly correlated with respiratory resistance(r=-0.700,P＜0.001),reaction thresh-old(r=0.704,P＜0.001),resistance increase slope(r=-0.842,P＜0.001),IgE(r=0.864,P＜0.001),ECP(r=-0.684,P＜0.001),and EOS(r=-0.854,P＜0.001).Con-clusion The decreased Foxp3 in peripheral blood in children with bronchial asthma is associated with aggravated airway hyper-responsiveness and body allergy,suggesting that Foxp3 may be in-volved in the pathogenesis of bronchial asthma.

Objective:To investigate the risk factors and their predictive efficacy for early postoperative complications in elderly patients with hip fracture.Methods:A retrospective cohort study was conducted on the clinical data of 203 elderly patients with hip fracture admitted to the 908th Hospital of the Joint Logistics Support Force of the PLA and the First Affiliated Hospital of Nanchang University from January 2022 to December 2023, including 54 males and 149 females, aged 65-100 years [(80.5±7.7)years]. There were 96 patients with femoral neck fracture and 107 patients with intertrochanteric fracture. According to the AO/OTA classification, the fracture was classified as type 31A in 107 patients and type 31B in 96. Among them, 81 patients were treated with proximal femoral nail antirotation (PFNA), 65 with semi-hip arthroplasty, 52 with total hip arthroplasty (THA), and 5 with closed reduction and cannulated nail internal fixation. The patients were divided into complication group ( n=65) and non-complication group ( n=138) according to whether complications (mainly including delirium, lung infection, stress ulcer, and deep vein thrombosis of the lower limbs) occurred within 15 days after surgery. The gender, age, age stage, educational level, cause of injury, associated underlying diseases before surgery, AO/OTA classification, American Society of Anesthesiologists (ASA) classification, 5-factor modified frailty index (mFI-5) score, prognostic nutritional index (PNI), anesthesia method, operation method, operation time, intraoperative blood loss, length of hospital stay, etc., were recorded in the two groups. Univariate analysis and multivariate binary logistic regression analysis were used to evaluate the correlation between the above indexes and the occurrence of early postoperative complications in elderly patients with hip fracture and to determine their independent risk factors. The receiver operating characteristic (ROC) curve was plotted and the area under the curve (AUC) was calculated to evaluate the predictive efficacy of each risk factor for the occurrence of early postoperative complications in elderly patients with hip fracture. Results:Univariate analysis showed a certain correlation between age, age stage, associated underlying diseases before surgery, AO/OTA classification, ASA classification, mFI-5 score, PNI, operation method, and length of hospital stay and the occurrence of early postoperative complications in elderly patients with hip fracture ( P<0.05), while gender, educational level, cause of injury, anesthesia method, operation time, and intraoperative blood loss were not correlated with the occurrence of early postoperative complications in elderly patients with hip fracture ( P>0.05). The results of multivariate binary logistic regression analysis showed that the associated underlying diseases before surgery ( OR=5.46, 95% CI 1.33, 22.39, P<0.05), mFI-5 score ( OR=15.90, 95% CI 5.36, 47.15, P<0.01), and PNI ( OR=0.70, 95% CI 0.60, 0.81, P<0.01) were significantly correlated with the occurrence of early postoperative complications in elderly patients with hip fracture. The results of ROC curve analysis showed that mFI-5 score (AUC=0.85, 95% CI 0.80, 0.91) and PNI (AUC=0.87, 95% CI 0.82, 0.93) had moderate predictive efficacy, while the early warning efficacy of associated underlying diseases was low (AUC=0.54, 95% CI 0.45, 0.62). The combination of the above risk factors was more effective in predicting early postoperative complications in elderly patients with hip fracture (AUC=0.95, 95% CI 0.92, 0.98). Conclusions:The mFI-5 score, PNI, and associated underlying diseases before surgery are independent risk factors for early postoperative complications in elderly patients with hip fracture. The mFI-5 score and PNI have a higher predictive efficacy than associated diseases before surgery on the occurrence of early postoperative complications in elderly patients with hip fracture, while the combination of the above risk factors provides a significantly better predictive performance.

Pharmacotranscriptomic profiles, which capture drug-induced changes in gene expression, offer vast potential for computational drug discovery and are widely used in modern medicine. However, current computational approaches neglected the associations within gene‒gene functional networks and unrevealed the systematic relationship between drug efficacy and the reversal effect. Here, we developed a new genome-scale functional module (GSFM) transformation framework to quantitatively evaluate drug efficacy for in silico drug discovery. GSFM employs four biologically interpretable quantifiers: GSFM_Up, GSFM_Down, GSFM_ssGSEA, and GSFM_TF to comprehensively evaluate the multi-dimension activities of each functional module (FM) at gene-level, pathway-level, and transcriptional regulatory network-level. Through a data transformation strategy, GSFM effectively converts noisy and potentially unreliable gene expression data into a more dependable FM active matrix, significantly outperforming other methods in terms of both robustness and accuracy. Besides, we found a positive correlation between RS_GSFM and drug efficacy, suggesting that RS_GSFM could serve as representative measure of drug efficacy. Furthermore, we identified WYE-354, perhexiline, and NTNCB as candidate therapeutic agents for the treatment of breast-invasive carcinoma, lung adenocarcinoma, and castration-resistant prostate cancer, respectively. The results from in vitro and in vivo experiments have validated that all identified compounds exhibit potent anti-tumor effects, providing proof-of-concept for our computational approach.

T-cell acute lymphoblastic leukemia (T-ALL) is a highly aggressive hematologic malignancy with a poor prognosis, despite advancements in treatment. Many patients struggle with relapse or refractory disease. Investigating the role of the super-enhancer (SE) regulated gene ubiquitin-specific protease 20 (USP20) in T-ALL could enhance targeted therapies and improve clinical outcomes. Analysis of histone H3 lysine 27 acetylation (H3K27ac) chromatin immunoprecipitation sequencing (ChIP-seq) data from six T-ALL cell lines and seven pediatric samples identified USP20 as an SE-regulated driver gene. Utilizing the Cancer Cell Line Encyclopedia (CCLE) and BloodSpot databases, it was found that USP20 is specifically highly expressed in T-ALL. Knocking down USP20 with short hairpin RNA (shRNA) increased apoptosis and inhibited proliferation in T-ALL cells. In vivo studies showed that USP20 knockdown reduced tumor growth and improved survival. The USP20 inhibitor GSK2643943A demonstrated similar anti-tumor effects. Mass spectrometry, RNA-Seq, and immunoprecipitation revealed that USP20 interacted with hypoxia-inducible factor 1 subunit alpha (HIF1A) and stabilized it by deubiquitination. Cleavage under targets and tagmentation (CUT&Tag) results indicated that USP20 co-localized with HIF1A, jointly modulating target genes in T-ALL. This study identifies USP20 as a therapeutic target in T-ALL and suggests GSK2643943A as a potential treatment strategy.
