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 study the effects of Qingre Lishi Prescription on ATP-P2X7R-IL-1β signaling pathway in rats with acute gouty arthritis.Methods:Otally 60 SPF-grade SD rats were divided into normal group, model group, colchicine group, and Qingre Lishi Prescription low-, medium- and high-dosage groups according to random number table method; the normal group and model group were given distilled water at a dosage of 10 ml/kg by gavage, the colchicine group was given colchicine solution at a dosage of 0.6 mg/kg by gavage, and Qingre Lishi Prescription low-, medium- and high-dosage groups were given Qingre Lishi Prescription extract suspension at dosages of 11.76, 23.52, and 47.04 g/kg by gavage, once a day for 7 consecutive days. Except for the normal group, AGA models were prepared by gavage on the 4th day in all other groups, and the swelling index of the right posterior ankle joint of rats was measured at 6, 12, 24, 48, and 72 hours after modeling; after 7 days of administration, samples were taken and HE staining was used to observe the pathological changes in the synovial tissue of the right posterior ankle joint. ELISA was used to detect the levels of serum ATP, IL-1 β, IL-8, and IL-37, and immunohistochemistry was used to detect the positive rates of P2X7R and IL-1 β proteins in the synovial tissue of the right posterior ankle joint.Results:At 6, 12, 24, 48, and 72 hours after modeling, compared with the model group, the swelling index of the colchicine group and Qingre Lishi Prescription low-dosage group decreased ( P<0.01); the levels of serum ATP, IL - β, IL-8, and IL-37 decreased in the colchicine group and Qingre Lishi Prescription low-, medium-, and high-dosage groups ( P<0.01); the expressions of P2X7R and IL-1 β proteins in the synovial tissue of the right posterior ankle was reduced in the colchicine group and Qingre Lishi Prescription high-dosage group ( P<0.05). Conclusion:Qingre Lishi Prescription may improve joint swelling and alleviate synovial tissue inflammation in AGA model rats through ATP/P2X7R/IL-1β-mediated inflammatory factor pathway.

Objective To investigate the clinical characteristics and management strategies of spinal infarction(SCI)combined with hypoxic-ischemic encephalopathy(HIE).Methods We report a case of SCI induced by cardiopulmonary arrest in a patient admitted to the General Hospital of Southern Theater Command in June 2021.A review of the relevant literature published in PubMed and CNKI from January 2014 to March 2024,was conducted to summarize the etiology,features,and treatment approaches for SCI.Results The patient presented with clinical features of quadriplegia accompanied by paresthesia,lumbar and cervical pain with paresthesia,dysphagia,dysphonia,and urinary and fecal incontinence.Spinal MRI revealed abnormal signals in the anterior and lateral columns at the C2-T1 spinal level,with no enhancement observed in contrast-enhanced scan.The patient was diagnosed as SCI combined with HIE,and was treated with antiplatelet therapy and rehabilitation.Literature review revealed that SCI is a rare central nervous system disease with multiple causes,often related to aortic surgery or pathology,presenting with segmental sensory disturbances among other clinical manifestations.MRI plays a significant role in its diagnosis,and there is currently no specific effective treatment available.Conclusions SCI has a sudden onset and is often insidious,frequently accompanying other diseases,leading to a high risk of misdiagnosis.In this case,SCI was considered to be caused by low blood pressure and vertebral artery tenuity.Clinical manifestations include paraplegia at the lesion level along with back/neck pain or limb paresthesia.Diagnosis primarily relies on MRI imaging while treatment involves secondary stroke prevention measures,rehabilitation training,complication prevention strategies as well as hyperbaric oxygen therapy.

Processing for deodorization is widely used in the production of animal-derived Chinese medicinal materials. In this study, Heracles Neo ultra-fast gas-phase electronic nose combined with chemometrics was employed to analyze the overall odor difference of Cervi Cornu Pantotrichum(focusing on that derived from Cervus nippon Temminck in this study) before and after processing. The results showed that the electronic nose effectively distinguished between the medicinal materials and decoction pieces of Cervi Cornu Pantotrichum. HS-GC-MS was used to identify and quantify the volatile components in the medicinal materials and decoction pieces of Cervi Cornu Pantotrichum, and 35 and 37 volatile components were detected in the medicinal materials and decoction pieces, respectively. The medicinal materials and decoction pieces contained 28 common volatile components contributing to the odor of Cervi Cornu Pantotrichum. The odor activity value(OAV) of each volatile component was calculated based on the olfactory threshold and relative content. The results showed that there were 17 key odor substances such as isovaleraldehyde, 2-methylbutanal, isobutyraldehyde, hexanal, and methanethiol in the medicinal materials and decoction pieces of Cervi Cornu Pantotrichum. All of them had bad odor and were the main source of the odor of Cervi Cornu Pantotrichum. The results of principal component analysis(PCA) and orthogonal partial least squares-discriminant analysis(OPLS-DA) showed that there were significant differences in volatile components between the medicinal materials and decoction pieces of Cervi Cornu Pantotrichum. Based on the thresholds of P<0.05 and Variable Importance in Projection(VIP)>1, 21 differential volatile odor components were screened out. Among them, isopentanol, isovaleraldehyde, 2-methylbutanal, n-nonanal, and dimethylamine were the key differential odor compounds between the medicinal materials and decoction pieces of Cervi Cornu Pantotrichum. The odor compounds and their relative content reduced, and some flavor substances such as esters were produced after processing with wine, which was the main reason for the reduction of the odor after processing of Cervi Cornu Pantotrichum.

Objective:To investigate the correlation of epithelial lesions among different biopsy sites in the female lower genital tract and the relationship between age and lesion distribution.Methods:A total of 406 148 patients with cervical biopsy specimens archived at the Department of Pathology, Obstetrics and Gynecology Hospital of Fudan University from January 2010 to December 2021 were analyzed. Among them, 70 309 cases (17.31%) had concurrent vaginal biopsies, and 16 073 cases (3.96%) had concurrent vulvar biopsies. (1) Cases were divided into four 3-year intervals to compare vaginal or vulvar biopsy rates and high-grade squamous intraepithelial lesion (HSIL) or worse (HSIL +) detection rates across time periods. (2) Correlations between cervical lesions and vaginal or vulvar lesions were assessed. (3) Patients were stratified into three age groups (<30, 30-49, and ≥50 years) to compare vaginal or vulvar HSIL + detection rates. Results:Mean ages of patients with cervical, vaginal, and vulvar biopsies were (41.3±11.0), (47.4±12.5), and (41.9±13.2) years, respectively. Patients with vaginal biopsy were significantly older than cervical or vulvar groups (all P<0.001). (1) Vaginal biopsy rates increased markedly from 7.37% (2010—2012) to 22.76% (2019—2021; χ2=9 205.01, P<0.001); vulvar biopsy rates increased slightly from 2.80% to 5.69% ( χ2=1 777.25, P<0.001). Correspondingly, vaginal HSIL + detection rates rose from 0.28% to >0.5% (0.56% in 2013—2015, 0.59% in 2016—2018, 0.51% in 2019—2021; χ2=134.70, P<0.001), while vulvar HSIL + rates increased from 0.03% to 0.33% ( χ2=56.54, P<0.001). (2) Weak correlation existed between cervical and vaginal lesions ( r=0.28; P<0.001; n=70 309), while cervical-vulvar correlation was weaker ( r=0.22, P<0.001; n=16 073). (3) Vaginal HSIL + detection rates were higher in cervical HSIL + patients aged 30-49 years (26.65%) and ≥50 years (26.79%) versus <30 years (14.63%; both P<0.001). Conversely, vulvar HSIL + detection rates were higher in the <30 years group (23.08%) versus 30-49 years (13.83%) and ≥50 years (12.89%; both P<0.05). Conclusions:Vaginal or vulvar lesion detection rates increase with biopsy frequency. Vaginal lesions correlate with cervical abnormalities, whereas vulvar lesions are relatively independent. In cervical HSIL + patients, those <30 years are more prone to have vulvar HSIL +, while those ≥30 years show higher vaginal HSIL + incidence. These age-specific distribution patterns inform optimized biopsy strategies.

AIM To investigate the effects of Shuyu Pills combined with evolimus on the epithelial mesenchymal transformation of triple negative breast cancer cells 4T1 and MDA-MB-231 induced by TGF-β1.METHODS The 4T1 and MDA-MB-231 cells were divided into the blank group and the induction group to induce the epithelial mesenchymal transformation with TGF-β1 cytokine treatment,followed by the assignment into the model group,the Shuyu Pills group,the everolimus group and the Shuyu Pills combined with everolimus group.CCK8 method,plate cloning method,cell scratch test and Transewll test were used to detect the proliferation,cloning formation,migration and invasion ability of the cells whose expressions of E-cadherin,N-cadherin,Vimentin,MMP9,MMP2 and pathway proteins PTEN,PI3K,Akt and mTOR were detected by Western blot.RESULTS Compared with the blank group,the induction group displayed a cell morphological change from epithelioid to stromal,decreased expression of E-cadherin protein(P＜0.01);and increased protein expressions of N-cadherin and Vimentin(P＜0.05).Compared with the model group,each group intervened with the medicine displayed decreased proliferation,clone formation,migration and invasion ability of both kinds of cells(P＜0.01);increased protein expressions of PTEN and E-cadherin(P＜0.05,P＜0.01);and decreased protein expressions of PI3K,Akt,mTOR,N-cadherin,Vimentin,MMP9 and MMP2(P＜0.05,P＜0.01);and more significantly in the Shuyu Pills combined with evolimus group(P＜0.05,P＜0.01).CONCLUSION With a more ideal effect than the single uses in inhibiting the TGF-β1-induced epithelial mesenchymal transformation of triple-negative breast cancer cells,the combination use of Shuyu Pills and everolimus may work through the regulation of PI3K/Akt/mTOR signaling pathway.

Objective To explore the mediating role of mobile phone dependency and self-rated health in the relationship between adverse childhood experiences(ACEs)and mental health among young adults.Methods A cross-sectional study was conducted using cluster random sampling among 1 611 young adults(mean age 26.30 years)from a region in Hainan Province.Participants completed the childhood trauma questionnaire(short form),the mobile phone addiction index,the depression-anxiety-stress scale(simplified Chinese version),and a self-rated health questionnaire.Pearson correlation analysis and mediation effect analysis were employed to examine the relationships among ACEs,mobile phone dependency,self-rated health,and mental health.Results ACEs,mobile phone dependency,and self-rated health were all significantly correlated with mental health(all P＜0.01).ACEs had a direct negative effect on mental health(direct effect=0.221,95%confidence interval[CI]0.150-0.293).Furthermore,ACEs exerted indirect effects on mental health through 3 pathways:the independent mediation of mobile phone dependency(indirect effect=0.081,95%CI 0.035-0.130),the independent mediation of self-rated health(indirect effect=0.034,95%CI 0.011-0.062),and the chain mediation of mobile phone dependency and self-rated health(indirect effect=0.009,95%CI 0.004-0.015).Conclusion ACEs have a significant impact on the mental health of young adults,with mobile phone dependency and self-rated health serving as key mediators.Interventions aimed at reducing mobile phone dependency and improving health status may help mitigate the negative impact of childhood trauma on mental health,thereby promoting psychological well-being in this population.

A pyrene-phenol-based fluorescent probe PyP which showed typical intramolecular charge transfer(ICT)and monomer-excimer activities was synthesized by using pyrene carboxaldehyde hydrazone and 4-tert-butyl-2,6-diformylphenol as the raw materials.The effects of solvents on PyP were studied,and the results showed that the color of protic polar solvents(Ethanol,N,N-dimethylformamide,methanol and H2O)were successfully identified.Based on the solvent polarity-regulated PyP monomer-excimer switching,the rapid and highly sensitive ratiometric probe,"Turn-off"and"Turn-on"multimodal probes were established for detection of trace water content in organic solvents(Dimethyl sulfoxide,N,N-dimethylformamide,ethanol and methanol),with detection limits(3σ/k)of 0.0021％,0.046％,0.062％and 0.024％.The method was successfully used to detect water content in dimethyl sulfoxide,N,N-dimethy lformamide,ethanol and methanol commercial organic solvents,with recoveries ranging from 97.2％to 108.0％.The developed method showed good accuracy and stability,and had good application prospect.
