Background/Aims: Acetyl coenzyme A (acetyl-CoA) is one of the most essential metabolites in cell metabolism but its function and concentration in hepatocellular carcinoma (HCC) remain elusive and controversial. Methods: A comprehensive analysis of acetyl-CoA levels and acetyl-CoA synthetase 2 (ACSS2) expression across a range of samples, including patient specimens from both hepatitis B virus (HBV) positive and HBV negative HCC individuals, HBV-transgenic mouse HCC models, and multiple cell lines. Furthermore, to evaluate the functional significance of ACSS2 in HBV-related HCC, we implemented both genetic and pharmacological inhibition strategies targeting ACSS2. Molecular mechanism and mitophagy assessment were revealed by cleavage under target and tagmentation sequencing, RNA sequencing, bioinformatic analyses, transmission electron microscopy and JC-1 staining. Results: Our study revealed a distinct metabolic signature of HBV-related HCC, marked by elevated acetyl-CoA, which was driven by ACSS2. ACSS2 was upregulated by the carbohydrate response element-binding protein in HBV-related HCC. Furthermore, ACSS2 improved tumor cell proliferation, an effect that was dependent on its enzymatic activity. Mechanistically, ACSS2-induced acetyl-CoA accumulation activated voltage-dependent anion channels 1 transcription through increased H3K27ac occupancy, which subsequently promoted mitophagy and HBV-related HCC tumorigenesis. Notably, targeting ACSS2 by depletion or inhibition with a catalytic inhibitor significantly suppressed tumor growth. Conclusions These findings not only illustrate the interplay between metabolic reprogramming, epigenetic modification, and tumorigenesis in the context of HBV infection, but also highlight ACSS2 as a novel metabolic vulnerability in HBV-related HCC. Therefore, targeting ACSS2 could be a novel strategy against HBV-related HCC.

Patients with lung cancer experience a heavy symptom burden during the perioperative period, which seriously affects their recovery and quality of life. Traditional symptom management models rely mainly on scheduled ward rounds during hospitalization and outpatient follow-up after discharge. However, they have limitations such as delayed symptom recognition, lack of post-discharge monitoring, and non-quantitative symptom assessment, which often lead to delayed interventions and low patient satisfaction. In recent years, the symptom management model based on electronic patient-reported outcomes (ePRO) has been increasingly valued in clinical practice. Existing high-level evidence from both domestic and international studies indicates that, through proactive monitoring, real-time alerts, and remote interventions, this model enables dynamic and continuous symptom management and helps improve patient recovery and healthcare experience. As a supplement to routine medical care, the ePRO-based symptom management model aims to enhance the quality of care rather than replace existing medical processes. To promote the standardized application of this model in perioperative lung cancer care, this consensus integrates domestic and international evidence. After multiple rounds of voting by more than 50 experts, it formulates 12 consensus statements covering the three core components, symptom monitoring, alerting, and intervention, to provide scientific and practical recommendations for clinical practice.

Objective To investigate the causes and management strategies for lower limb ischemic necrosis following xenogeneic heterotopic heart transplantation from a multigene-edited pig to a rhesus monkey. Methods A xenogeneic heterotopic heart transplantation was performed on December 16, 2023, at the Institute of Experimental Animals of Sichuan Academy of Medical Sciences & Sichuan Provincial People's Hospital, using a quintuple-gene-edited pig as the donor and a rhesus monkey as the recipient. On postoperative day (POD) 9, the recipient monkey underwent left lower limb amputation due to ischemic necrosis. Blood samples were collected at various time points after transplantation for analysis of hematologic parameters, liver and renal function, myocardial enzymes, and coagulation profiles. Ultrasound and computed tomography (CT) were used to evaluate anastomotic patency and cardiac structure. Immunological assays, including complement-dependent cytotoxicity (CDC) and IgG/IgM antibody detection, combined with clinical observations, were employed to assess rejection type and therapeutic response. Results The recipient monkey survived for 46 days after transplantation. Echocardiography demonstrated preserved biventricular systolic function in the recipient’s native heart, with left ventricular ejection fraction (LVEF) consistently exceeding 50%. In the donor pig heart, left ventricular endocardial thickening was noted on POD 9, followed by right ventricular endocardial thickening on POD 24, while LVEF remained around 35%. No hyperacute or acute rejection was detected immunologically. CDC positivity ranged between 3.4% and 5.1%, with IgG/IgM antibody binding trends consistent with CDC results. Following amputation, the recipient exhibited elevated inflammatory markers, coagulopathy, and reactive thrombocytosis, which later normalized. Immunohistochemical staining of the necrotic limb revealed arterial and venous thrombosis; however, no T-cell or B-cell infiltration was observed in vascular structures, thrombi, nerves, muscles, fascia, or skin tissues, with CD3 and CD20 staining both negative. Conclusion Limb ischemia after xenogeneic heart transplantation may be associated with lower extremity vascular thrombosis triggered by local trauma in the context of transplantation-induced inflammatory activation and coagulation dysfunction. While no clear lymphocyte-mediated rejection was observed, further studies are needed to explore the potential role of non-lymphocyte-mediated immune mechanisms.

Objective With the comprehensive implementation of Diagnosis-Related Groups(DRG)and Diagnosis-In-tervention Packet(DIP)payment reforms,ambulatory surgery has been widely adopted in clinical practice due to its efficiency and cost-effectiveness.However,medical insurance compliance issues have become increasingly prominent during management processes.Standardizing ambulatory surgery management and ensuring the security of medical insurance funds have grown in im-portance.Methods Based on the current status of ambulatory surgery medical insurance policies in Tianjin,this study analyzes common compliance issues under DRG/DIP payment systems,explores their causes,and proposes targeted management strate-gies.Results Tianjin currently has 786 ambulatory surgery procedures,with orthopedics being the most common specialty,fol-lowed by ophthalmology,urology,and general surgery.From 2020 to 2024,the sample hospital completed 12,705 ambulatory surgery cases,with a significant increase in 2024.In 2020,the most frequent procedure was circumcision,while in 2024,it was colonoscopic polypectomy.Under DRG/DIP payment systems,common medical insurance compliance issues include upeoding,split hospitalization,excessive treatment,cost shifting,and undertreatment.Conclusion Healthcare and medical insurance sys-tems should collaborate to implement targeted management strategies.These include strengthening hospital medical record and coding management,improving medical quality control,refining medical insurance supervision mechanisms and payment stand-ards,and establishing a multi-stakeholder collaborative oversight system.These measures aim to standardize ambulatory surgery management,safeguard medical insurance funds,and promote the healthy development of the healthcare industry.

Objective:To analyze the clinical features and pathogenic genes of a family with congenital cataracts.Methods:A pedigree analysis was performed.A Han Chinese family initially diagnosed with congenital cataracts at The Fourth Hospital of Shijiazhuang in March 2024 was enrolled.The proband and selected family members underwent detailed ophthalmic examinations.Potential cataract-associated genetic variants in the proband were identified using whole exome sequencing (WES). Sanger sequencing was employed to confirm the presence of these variants in the proband and other family members.The identified variants were analyzed in accordance with the guidelines of the American College of Medical Genetics and Genomics (ACMG). This study adhered to the Declaration of Helsinki.The research protocol was approved by the Ethics Committee of The Fourth Hospital of Shijiazhuang (No.20230074). Both the subjects and their guardians were informed of the study purpose and voluntarily signed the informed consent form.Results:The pedigree included four generations comprising 15 individuals, with three patients identified across the second, third, and fourth generations.These cases included two males and one female, specifically the proband, his mother, and his eldest son.The observed inheritance pattern aligned with an autosomal dominant mode, characterized by the clinical presentation of bilateral cataracts.WES identified a novel frameshift insertion variant c. 270_271insA in exon 2 of the CRYAB gene in the proband, resulting in a valine-to-serine substitution at amino acid position 91.This variant induced early termination of translation following the expression of two additional amino acids, loss of 84 amino acids (p.V91Sfs2) and the production of a functionally impaired protein.The Sanger sequencing validation results were consistent with the co-segregation.According to the ACMG classification criteria (PM2+ PP1+ PVS1), the variant was classified as likely pathogenic. Conclusions:The frameshift insertion variant c. 270_271insA (p.V91Sfs2) in exon 2 of the CRYAB gene is likely the pathogenic cause of congenital cataract in this family.This is the first report of this variant.

Objective:To construct an integrated management model for early screening and diagnosis of PCa based on the In-novative Care for Chronic Conditions Framework(ICCC)and the 1+1 contract-based tiered diagnosis and treatment system(TDTS)in China.Methods:Based on the 1+1 contract-based TDTS platform,we conducted PCa screening for the male residents aged 60 years and above during health check-ups in Pujin Community Health Center from January 1,2023 to December 31,2023.For those with abnormal total prostate-specific antigen(tPSA)≥4 μg/L,we promptly referred them to higher-level hospitals for further diagno-sis and treatment via the two-way referral green channel platform and information sharing service using the 1+1 contract model.We further analyzed the relevant data on screening and diagnosis.Results:A total of 4 080 males aged 71.39±5.059 years received PCa screening from January to December 2023.PSA screening was performed in 43.96％of the male residents,revealing 654 cases of PSA abnormality,with a PSA positivity rate of 16.03％,which was higher than that found in the previous large-scale PCa screenings in other regions of China.Among the males with PSA abnormality,292(44.65％)expressed their willingness for medical referral,while the others did not seek further medical attention for reasons of being asymptomatic,low awareness of the disease,no accompany for medical visits,and concerns about further costs of diagnosis and treatment.Prostate biopsy was recommended to 154 cases after further examinations,which was accepted by 92(59.74％).Fifty-eight cases were diagnosed with Pa,and thedetection rate reached 63.04％.Conclusion:The integrated management model for PSA examination-based early screening and diagnosis of PCa using the 1+1 contract-based TDTS platform is plays a significant role in enhancing peoples awareness and knowledge of PCa and improving the early detection rate of the malignancy.

Objective:To investigate the predictive value of serum neutrophil gelatinase-associated lipocalin(NGAL),calcitonin gene-related peptide(CGRP),and neutrophil-to-lymphocyte ratio(NLR)for the prognostic regression of elderly patients with stroke complicated with pulmonary infection(SCPI).Methods:This study was a retrospective single-center study,149 elderly patients with SCPI who were admitted to Inner Mongolia Baogang Hospital from June 2020 to June 2024 were selected,they were divided into poor prognosis group(n=56)and good prognosis group(n=93)according to the prognosis.Baseline data and laboratory test indicators were collected,and NLR was calculated.Serum NGAL and CGRP levels were measured by ELISA.Influencing factors of poor prognosis of elderly patients with SCPI were analyzed by Multivariate logistic regression.Predicts value was analyzed by Receiver operating characteristic(ROC)curve.Results:Compared with good prognosis group,the poor prognosis group had higher of aged ≥ 70 years,incidence of hemorrhagic stroke,serum creatinine,white blood cell count,national institute of health stroke scale(NIHSS),platelet count,C-reactive protein,NGAL,and NLR levels,longer nerosurgery intensive care unit(NICU)stay,and lower CGRP levels(P＜0.05).Higher CGRP level was an independent protective factor of poor prognosis of elderly patients with SCPI(OR＜1,P＜0.05).Age ≥ 70 years,hemorrhagic stroke,longer NICU stay,higher NIHSS score,higher NGAL level and higher NLR were independent risk factors of poor prognosis of elderly patients with SCPI(OR＞1,P＜0.05).The area under the curve(AUC)for predicting the prognostic regression of elderly patients with SCPI used NGAL,CGRP,and NLR alone or in combination was 0.777,0.771,0.786,and 0.927,respectively,with the combination of three factors showed the highest predictive power(P＜0.05).Conclusion:Age ≥70 years,hemorrhagic stroke,longer NICU stay,higher NIHSS score,higher NGAL level and higher NLR are independent risk factors of poor prognosis of elderly patients with SCPI,while higher CGRP level is an independent protective factor.The combination detection of NGAL,CGRP and NLR can improve the predictive value of prognostic regression in elderly patients with SCPI.

Objective:To explore biomarkers for the efficacy of lymphocyte immunotherapy (LIT) treating women with unexplained recurrent spontaneous abortion (URSA).Methods:Serum samples from 24 URSA potients who received LIT were collected at Peking University Third Hospital from December 2014 to June 2015. Semiquantitative sandwich-based antibody arrays containing 40 cytokines were used to screen target immune cytokines in the peripheral blood of URSA patients before and after LIT. Multifactor quantitative microsphere flow cytometry detection validated the levels of target cytokines. Based on the final pregnancy outcome after LIT, 24 URSA patients were divided into the full-term delivery group (15 cases) and the abortion group (9 cases). Furthermore, linear regression analysis were applied to evaluate the relationship between target cytokines and pregnancy outcomes.Results:Semiquantitative sandwich-based antibody arrays suggested that, among all 24 URSA patients included in this study, the intensities of the fluorescence signal were significantly lower post-LIT versus pre-LIT for the following cytokines: interleukin-15 (IL-15), monokine induced by γ-interferon (MIG), C-C motif chemokine ligand (CCL) 1 (all P<0.05). In the full-term delivery group, the intensities of the fluorescence signal post-LIT were significantly lower than pre-LIT for the following cytokines: IL-15, CCL1, macrophage inflammatory protein (MIP) 1α (all P<0.05). In the abortion group, the intensities of the fluorescence signal post-LIT were significantly lower than pre-LIT for the following cytokines: MIG, MIP-1δ (all P<0.05). Linear regression analysis showed that the intensity of the fluorescence signal of CCL11 was increased and the intensity of the fluorescence signal of soluble tumor necrosis factor receptor 2 (sTNFR2) was decreased in the full-term delivery group after LIT, the differences were statistically significant ( P=0.012, 0.029). Validation results of multifactor quantitative microsphere flow cytometry detection showed that the level of CCL11 was significantly increased ( P=0.001) and the level of sTNFR2 was significantly decreased ( P=0.001) in the full-term delivery group after LIT. Conclusion:CCL11 and sTNFR2 maybe serve as potential biomarkers that could predict pregnancy outcomes after LIT in women with URSA.
