Chronic heart failure is the terminal stage of various cardiovascular diseases， and cardiomyocyte apoptosis is the turning point of decompensation. Studies have shown that traditional Chinese medicine （TCM） could regulate apoptosis-related signaling pathways and factors and inhibit or up-regulate the expression of apoptosis-related proteins. Thus， TCM can reduce cardiomyocyte apoptosis， protect the myocardial tissue and improve the cardiac function， demonstrating remarkable clinical effects. In recent years， the research on the treatment of chronic heart failure based on the inhibition of cardiomyocyte apoptosis is increasing and becomes the current research hotspot. On the basis of literature review， this paper discovers that TCM regulates apoptosis factors and multiple signaling pathways to inhibit apoptosis and inflammation and delay the progression of chronic heart failure through classical pathways such as the death receptor pathway， the mitochondrial pathway， and the endoplasmic reticulum pathway. At the same time， the studies in this field have the following problems： Repeated studies with shallow， simple， and fragmented contents， treating animal models with TCM prescriptions without syndrome differentiation， treating diseases with drugs at only one concentration which is insufficient to indicate efficacy， and lacking comprehensive， holistic， and systematic studies on the relationships of apoptosis with inflammatory responses， pyroptosis， ferroptosis， and autophagy. In the future， more scientific， reasonable， comprehensive， and feasible experimental schemes should be designed on the basis of comprehensively mastering the research progress in this field， and the communication and cooperation between researchers in different disciplines should be strengthened. The specific pathological mechanism of cardiomyocyte apoptosis in chronic heart failure and the signaling pathways， active components， and action targets of TCM in inhibiting cardiomyocyte apoptosis in chronic heart failure should be elucidated. Such efforts are expected to provide sufficient reference for the clinical treatment of chronic heart failure.

Since the Asia-Pacific Association for the Study of the Liver （APASL） issued the clinical practice guidelines for metabolic associated fatty liver disease （MAFLD） in 2020， the research on MAFLD has been further deepened. Therefore， APASL has made comprehensive updates and revisions based on the previous guidelines， and the latest version of the clinical practice guidelines for diagnosis and management of MAFLD， which was released in February 2025， has updated the epidemiology， screening， assessment， and treatment of MAFLD， aiming to promote the clinical practice， knowledge popularization， and scientific research of MAFLD. This article makes an excerpt and an interpretation of the updated key points of the guidelines.

BACKGROUND: At present, biopsy is essential for the diagnosis of prostate cancer (PCa) before radical prostatectomy (RP). However, with the development of prostate-specific membrane antigen positron emission tomography/computed tomography (PSMA PET/CT) and multiparametric magnetic resonance imaging (mpMRI), it might be feasible to avoid biopsy before RP. Herein, we aimed to explore the feasibility of avoiding biopsy before RP in patients highly suspected of having PCa after assessment of PSMA PET/CT and mpMRI. METHODS: Between December 2017 and April 2022, 56 patients with maximum standardized uptake value (SUVmax) of ≥4 and Prostate Imaging Reporting and Data System (PI-RADS) ≥4 lesions who received RP without preoperative biopsy were enrolled from two tertiary hospitals. The consistency between clinical and pathological diagnoses was evaluated. Preoperative characteristics were compared among patients with different pathological types, T stages, International Society of Urological Pathology (ISUP) grades, and European Association of Urology (EAU) risk groups. RESULTS: Fifty-five (98%) patients were confirmed with PCa by pathology, including 49 (89%) with clinically significant prostate cancer (csPCa, defined as ISUP grade ≥2 malignancy). One patient was diagnosed with high-grade prostatic intraepithelial neoplasia (HGPIN). CsPCa patients, compared with clinically insignificant prostate cancer (cisPCa) and HGPIN patients, were associated with a higher level of prostate-specific antigen (22.9 ng/mL vs . 10.0 ng/mL, P = 0.032), a lower median prostate volume (32.2 mL vs . 65.0 mL, P = 0.001), and a higher median SUVmax (13.3 vs . 5.6, P <0.001). CONCLUSIONS It might be feasible to avoid biopsy before RP for patients with a high probability of PCa based on PSMA PET/CT and mpMRI. However, the diagnostic efficacy of csPCa with PI-RADS ≥4 and SUVmax of ≥4 is inadequate for performing a procedure such as RP. Further prospective multicenter studies with larger sample sizes are necessary to confirm our perspectives and establish predictive models with PSMA PET/CT and mpMRI.

BACKGROUND: Durvalumab after chemoradiotherapy (CRT) failed to bring survival benefits to patients with epidermal growth factor receptor ( EGFR ) mutations in PACIFIC study (evaluating durvalumab in patients with stage III, unresectable NSCLC who did not have disease progression after concurrent chemoradiotherapy). We aimed to explore whether locally advanced inoperable patients with EGFR mutations benefit from tyrosine kinase inhibitors (TKIs) and the optimal treatment regimen. METHODS: We searched the PubMed, Embase, the Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov databases from inception to December 31, 2022 and performed a meta-analysis based on a Bayesian framework, with progression-free survival (PFS) and overall survival (OS) as the primary endpoints. RESULTS: A total of 1156 patients were identified in 16 studies that included 6 treatment measures, including CRT, CRT followed by durvalumab (CRT-Durva), TKI monotherapy, radiotherapy combined with TKI (RT-TKI), CRT combined with TKI (CRT-TKI), and TKI combined with durvalumab (TKI-Durva). The PFS of patients treated with TKI-containing regimens was significantly longer than that of patients treated with TKI-free regimens (hazard ratio [HR] = 0.37, 95% confidence interval [CI], 0.20-0.66). The PFS of TKI monotherapy was significantly longer than that of CRT (HR = 0.66, 95% CI, 0.50-0.87) but shorter than RT-TKI (HR = 1.78, 95% CI, 1.17-2.67). Furthermore, the PFS of RT-TKI or CRT-TKI were both significantly longer than that of CRT or CRT-Durva. RT-TKI ranked first in the Bayesian ranking, with the longest OS (60.8 months, 95% CI = 37.2-84.3 months) and the longest PFS (21.5 months, 95% CI, 15.4-27.5 months) in integrated analysis. CONCLUSIONS: For unresectable stage III EGFR mutant NSCLC, RT and TKI are both essential. Based on the current evidence, RT-TKI brings a superior survival advantage, while CRT-TKI needs further estimation. Large randomized clinical trials are urgently needed to explore the appropriate application sequences of TKI, radiotherapy, and chemotherapy.

OBJECTIVE: To propose a new protocol for personalized mandibular reconstruction assisted by three-dimensional (3D) retrieval model based on fully connected neural network (FCNN) and a database of mandibles, and to verify clinical feasibility of the protocol. METHODS: A database of mandibles of 300 normal northern Chinese Han people was established. On the basis of cephalometry, the mandible landmarks with good stability were further screened. Mandibular landmarks were selected and geometric features of the mandible were extracted. A 3D retrieval algorithm was developed, which could retrieve the mandible most similar to a given mandible from the database. A FCNN was built to train the algorithm to improve accuracy of the 3D retrieval model. Using Geomagic Control 2014 software, matching accuracy of the 3D retrieval model was based on aforementioned mandible database and algorithm. From December 2019 to March 2021, a total of 5 patients underwent personalized mandibular reconstruction assisted by a 3D retrieval model based on mandible database and FCNN in the Department of Oral and Maxillofacial Surgery, Peking University School and Hospital of Stomatology. The most similar mandible was retrieved from mandible database through 3D retrieval algorithm. It was used to restore the premorbid morphology of defect area and guide mandibular reconstruction. For the 5 patients, mandible was reconstructed with iliac flap. Virtual surgical plan was transformed using individual surgical guides. RESULTS: Through screening, mandibular landmarks with high reproducibility and stability were identified and composed of mandibular landmarker protocols. After training, the average deviation between most similar mandible retrieved from the 300-case mandible database through 3D retrieval model based on FCNN and given mandible was (1.77±0.44) mm. And the root-mean-square deviation between the most similar mandible retrieved from the database and given mandible was (2.58±0.86) mm. The mandibular reconstruction surgery was successful in all the 5 patients. Their facial symmetry and occlusion were restored. All the patients were satisfied with postoperative appearance. The mean deviation between postoperative mandible and preoperative design was (0.98±0.17) mm. The area with a deviation ≤1 mm accounted for 61.34%±14. 13%, ≤2 mm accounted for 83.82%±7.35%, and ≤3 mm accounted for 93.94%± 2.87%. CONCLUSION The personalized mandibular reconstruction assisted by 3D retrieval model based on the 300-case mandible database and FCNN is feasible clinically.

Homo- or heterodimeric compounds that affect dimeric protein function through interaction between monomeric moieties and protein subunits can serve as valuable sources of potent and selective drug candidates. Here, we screened an in-house dimeric natural product collection, and panepocyclinol A (PecA) emerged as a selective and potent STAT3 inhibitor with profound anti-tumor efficacy. Through cross-linking C712/C718 residues in separate STAT3 monomers with two distinct Michael receptors, PecA inhibits STAT3 DNA binding affinity and transcription activity. Molecular dynamics simulation reveals the key conformation changes of STAT3 dimers upon the di-covalent binding with PecA that abolishes its DNA interactions. Furthermore, PecA exhibits high efficacy against anaplastic large T cell lymphoma in vitro and in vivo, especially those with constitutively activated STAT3 or STAT3^Y640F. In summary, our study describes a distinct and effective di-covalent modification for the dimeric compound PecA to disrupt STAT3 function.

Hepatic stellate cells (HSCs) are the primary fibrogenic cells in the liver, and their activation plays a crucial role in the development and progression of hepatic fibrosis. Here, we report that retinoid X receptor-alpha (RXRα), a unique member of the nuclear receptor superfamily, is a key modulator of HSC activation and liver fibrosis. RXRα exerts its effects by modulating calcium/calmodulin-dependent protein kinase kinase β (CaMKKβ)-mediated activation of AMP-activated protein kinase-alpha (AMPKα). In addition, we demonstrate that K-80003, which binds RXRα by a unique mechanism, effectively suppresses HSC activation, proliferation, and migration, thereby inhibiting liver fibrosis in the CCl₄ and amylin liver NASH (AMLN) diet animal models. The effect is mediated by AMPKα activation, promoting mitophagy in HSCs. Mechanistically, K-80003 activates AMPKα by inducing RXRα to form condensates with CaMKKβ and AMPKα via a two-phase process. The formation of RXRα condensates is driven by its N-terminal intrinsic disorder region and requires phosphorylation by CaMKKβ. Our results reveal a crucial role of RXRα in liver fibrosis regulation through modulating mitochondrial activities in HSCs. Furthermore, they suggest that K-80003 and related RXRα modulators hold promise as therapeutic agents for fibrosis-related diseases.

ObjectiveTo analyze and assess the pollution levels of lead （Pb）， cadmium （Cd）， and chromium （Cr） in rural soils of Wanzhou District， Chongqing Municipality， and to provide data support for proposing relevant measures and suggestions. MethodsBased on the soil monitoring data from 2017 to 2021， the ecological risk assessment was conducted by applying the Soil Pollution Risk Control Standard for Agricultural Land of Soil Environmental Quality （for trial implementation） （GB 15168‒2018）， the pollution index method and the potential ecological risk method. ResultsA total of 100 soil samples were collected， with pH values ranged from 3.50 to 8.30， and a mean value of 6.10. The mean values of Pb， Cd， and Cr in the soil were 25.2 mg·kg^-1， 0.310 mg·kg^-1， and 68.6 mg·kg^-1， respectively. Except for Cr， the mean values of other elements exceeded the soil background values. Cd level had the largest coefficient of variation and uneven spatial distribution， with an overall exceedance rate of 30.0%. Pollution levels of Pb and Cr were generally at the alert level， while Cd was generally at a light pollution level. The proportion of Cd pollution levels was higher than that of Pb and Cr， and the difference was statistically significant（χ²=15.015， P=0.001）. The Nemerow comprehensive pollution index in different townships ranged from 0.70 to 2.07， with a median value of 1.10， and was generally at a light pollution level. The potential ecological hazard risk of Cd was relatively high， and was generally at a mild level of hazard. The highest contribution rate in the comprehensive potential ecological hazard index was Cd， accounting for 84.1%. ConclusionThere is a certain degree of Cd pollution and mild ecological risk in rural soils of Wanzhou District. Monitoring and management of Cd pollution in rural soils of Wanzhou District， Chongqing Municipality， should be strengthened.

AIM: To systematically evaluate the efficacy and safety of low-concentrations atropine eye drops in controlling adolescent myopia.METHODS:A computer search was conducted on Wanfang Data, CNKI, VIP, PubMed, Cochrane Library, and Embase databases from January 2010 to March 2024 on clinical studies on low-concentration atropine eye drops for controlling adolescent myopia. Two researchers independently screened trials, extracted data, evaluated risk of bias and quality, and used Review Manager5.4 software to perform Meta-analysis.RESULTS:A total of 17 articles, involving 3 764 cases and 3 952 eyes, were included. The Meta-analysis showed that compared with the control group, low concentrations of atropine could effectively slow down the growth of axial length [MD=-0.15, 95% CI(-0.20, -0.10), P<0.00001], significantly controlled the changes in spherical equivalent [MD=0.39, 95% CI(0.29, 0.48), P<0.00001], and had a significant effect on pupil diameter [MD=0.80, 95% CI(0.33,1.28), P=0.0010] and amplitude of accommodation [MD=-2.54, 95%CI(-4.49, -0.60), P=0.01].CONCLUSION:Low-concentrations atropine are effective in controlling spherical equivalent and axial length of myopia in adolescents, significantly affecting pupil diameter and amplitude of accommodation, and effectively delaying the progression of myopia.
