OBJECTIVE To improve the quality standard of Zhuang medicine Yingbupu （Aralia armata）. METHODS A total of 23 batches of Yingbupu （A. armata） were studied. Their macroscopic characteristics and powder microscopic features were observed. TLC was employed for the qualitative identification of oleanolic acid and araloside A. Items such as water content， total ash， acid-insoluble ash， and ethanol-soluble extract were determined according to the methods specified in the 2020 edition of the Chinese Pharmacopoeia （part Ⅳ）. UPLC fingerprint was established for 23 batches of samples by using Similarity Evaluation System for Chromatographic Fingerprints of Traditional Chinese Medicine （2012 edition）， and the contents of oleanolic acid and araloside A were determined. RESULTS The powder microscopic characteristics of the medicinal material were distinctive. Oleanolic acid and araloside A were detected by TLC in all 23 batches. Among the 23 batches of samples， the content ranges of moisture， total ash， acid-insoluble ash， and ethanol-soluble extract were 6.9% to 10.4%， 1.8% to 6.8%， 0.1% to 1.9%， and 2.8% to 8.4%， respectively. Based on the UPLC fingerprint， a total of 15 common peaks were obtained， and 9 of these common peaks were identified. The content ranges of oleanolic acid and araloside A in the 23 batches of samples were 0.86% to 2.69% and 0.16% to 1.10%， respectively. CONCLUSIONS This study has added items such as moisture and total ash content fingerprint， TLC identification. A preliminary quality standard has been established for the medicinal material of Yingbupu （A. armata）， stipulating that the moisture content should not exceed 11.0%， the total ash content should not exceed 5.0%， the acid-insoluble ash content should not exceed 2.5%， the ethanol-soluble extract（No. content should not be less than 4.0%， and the contents of zyyzdxk-2023165） oleanolic acid and araloside A should not be less than 1.00% and 0.45%（ calculated by a dried basis）， respectively.

The study aims to examine the effects and potential mechanisms of disulfiram (DSF) on cardiac hypertrophic injury, focusing on the role of transforming growth factor-β-activated kinase 1 (TAK1)-mediated pan-apoptosis (PANoptosis). H9C2 cardiomyocytes were treated with angiotensin II (Ang II, 1 µmol/L) to establish an in vitro model of myocardial hypertrophy. DSF (40 µmol/L) was used to treat cardiomyocyte hypertrophic injury models, either along or in combination with the TAK1 inhibitor, 5z-7-oxozeaenol (5z-7, 0.1 µmol/L). We assessed cell damage using propidium iodide (PI) staining, measured cell viability with CCK8 assay, quantified inflammatory factor levels in cell culture media via ELISA, detected TAK1 and RIPK1 binding rates using immunoprecipitation, and analyzed the protein expression levels of key proteins in the TAK1-mediated PANoptosis pathway using Western blot. In addition, the surface area of cardiomyocytes was measured with Phalloidin staining. The results showed that Ang II significantly reduced the cellular viability of H9C2 cardiomyocytes and the binding rate of TAK1 and RIPK1, significantly increased the surface area of H9C2 cardiomyocytes, PI staining positive rate, levels of inflammatory factors [interleukin-1β (IL-1β), IL-18, and tumor necrosis factor α (TNF-α)] in cell culture media and p-TAK1/TAK1 ratio, and significantly up-regulated key proteins in the PANoptosis pathway [pyroptosis-related proteins NLRP3, Caspase-1 (p20), and GSDMD-N (p30), apoptosis-related proteins Caspase-3 (p17), Caspase-7 (p20), and Caspase-8 (p18), as well as necroptosis-related proteins p-MLKL, RIPK1, and RIPK3]. DSF significantly reversed the above changes induced by Ang II. Both 5z-7 and exogenous IL-1β weakened these cardioprotective effects of DSF. These results suggest that DSF may alleviate cardiac hypertrophic injury by inhibiting TAK1-mediated PANoptosis.

OBJECTIVE: To evaluate the safety and effectiveness of robot-assisted percutaneous coronary intervention (R-PCI) compared to traditional manual percutaneous coronary intervention (M-PCI). METHODS: This prospective, multicenter, randomized controlled, non-inferior clinical trial enrolled patients with coronary heart disease who met the inclusion criteria and had indications for elective percutaneous coronary intervention. Participants were randomly assigned to either the R-PCI group or the M-PCI group. Primary endpoints were clinical and technical success rates. Clinical success was defined as visually estimated residual post-percutaneous coronary intervention stenosis < 30% with no 30-day major adverse cardiac events. Technical success in the R-PCI group was defined as successful completion of percutaneous coronary intervention using the ETcath200 robot-assisted system, without conversion to M-PCI in the event of a guidewire or balloon/stent catheter that was unable to cross the vessel or was poorly supported by the catheter. Secondary endpoints included total procedure time, percutaneous coronary intervention procedure time, fluoroscopy time, contrast volume, operator radiation exposure, air kerma, and dose-area product. RESULTS: The trial enrolled 152 patients (R-PCI: 73 patients, M-PCI: 79 patients). Lesions were predominantly B2/C type (73.6%). Both groups achieved 100% clinical success rate. No major adverse cardiac events occurred during the 30-day follow-up. The R-PCI group had a technical success rate of 100%. The R-PCI group had longer total procedure and fluoroscopy times, but lower operator radiation exposure. The percutaneous coronary intervention procedure time, contrast volume, air kerma, and dose-area product were similar between the two groups. CONCLUSIONS For certain complex lesions, performing percutaneous coronary intervention using the ETcath200 robot-assisted system is safe and effective and does not result in conversion to M-PCI.

Hearing loss is the most prevalent disabling disease. Cochlear implantation（CI） serves as the primary intervention for severe to profound hearing loss. This consensus systematically explores the value of genetic diagnosis in the pre-operative assessment and efficacy prognosis for CI. Drawing upon domestic and international research and clinical experience, it proposes an evidence-based medicine three-tiered prognostic classification system（Favorable, Marginal, Poor）. The consensus focuses on common hereditary non-syndromic hearing loss（such as that caused by mutations in genes like GJB2, SLC26A4, OTOF, LOXHD1） and syndromic hereditary hearing loss（such as Jervell & Lange-Nielsen syndrome and Waardenburg syndrome）, which are closely associated with congenital hearing loss, analyzing the impact of their pathological mechanisms on CI outcomes. The consensus provides recommendations based on multiple round of expert discussion and voting. It emphasizes that genetic diagnosis can optimize patient selection, predict prognosis, guide post-operative rehabilitation, offer stratified management strategies for patients with different genotypes, and advance the application of precision medicine in the field of CI.

OBJECTIVE: This study aimed to explore the association between body mass index (BMI) and mortality based on the 10-year population-based multicenter prospective study. METHODS: A general population-based multicenter prospective study was conducted at four sites in rural China between 2013 and 2023. Multivariate Cox proportional hazards models and restricted cubic spline analyses were used to assess the association between BMI and mortality. Stratified analyses were performed based on the individual characteristics of the participants. RESULTS: Overall, 19,107 participants with a sum of 163,095 person-years were included and 1,910 participants died. The underweight (< 18.5 kg/m ²) presented an increase in all-cause mortality (adjusted hazards ratio [ aHR] = 2.00, 95% confidence interval [ CI]: 1.66-2.41), while overweight (≥ 24.0 to < 28.0 kg/m ²) and obesity (≥ 28.0 kg/m ²) presented a decrease with an aHR of 0.61 (95% CI: 0.52-0.73) and 0.51 (95% CI: 0.37-0.70), respectively. Overweight ( aHR = 0.76, 95% CI: 0.67-0.86) and mild obesity ( aHR = 0.72, 95% CI: 0.59-0.87) had a positive impact on mortality in people older than 60 years. All-cause mortality decreased rapidly until reaching a BMI of 25.7 kg/m ² ( aHR = 0.95, 95% CI: 0.92-0.98) and increased slightly above that value, indicating a U-shaped association. The beneficial impact of being overweight on mortality was robust in most subgroups and sensitivity analyses. CONCLUSION This study provides additional evidence that overweight and mild obesity may be inversely related to the risk of death in individuals older than 60 years. Therefore, it is essential to consider age differences when formulating health and weight management strategies.

Aim To investigate the effects of bone-forming protein BMP9 on aerobic glycolysis,migration and invasion ability in triple-negative breast cancer MDA-MB-231 cells and the underlying mechanisms.Methods The experimental group infected MDA-MB-231 cells with human BMP9 recombinant adenovirus(AdBMP9),while the control group infected cells with empty GFP adenovirus.Lactate,glucose and ATP as-say kits were used to detect glucose uptake,lactate and ATP production.The correlation between BMP9 and key glycolytic enzyme genes in pancarcinoma was ana-lyzed using GEPIA2 database.The mRNA expression levels of GLUT1,HK2,PKM2 and LDHA in MDA-MB-231 cells after overexpression of BMP9 were detec-ted by qRT-PCR.Potential targets of BMP9 inhibiting MDA-MB-231 aerobic glycolysis were analyzed in STRING database.The expression levels of HIF-1αand downstream protein were detected by Western blot.The changes of cell migration and invasion ability after different treatments were evaluated by the scratch heal-ing assay and Transwell assay.Results Compared with the control group,BMP9 down-regulated glucose uptake,lactate production,ATP level(P＜0.01),and inhibited HIF-1α and its downstream protein ex-pression in MDA-MB-231 cells.Overexpression of HIF-1α in rescue experiment reversed the inhibitory effect of BMP9 on aerobic glycolysis,migration and in-vasion of MDA-MB-231 breast cancer cells.Conclu-sion BMP9 down-regulates HIF-1α to inhibit the aer-obic glycolysis and migration and invasion ability of MDA-MB-231 breast cancer cells.

Aim To investigate the effects of autophagy regula-ted by LncRNA SNHG3 on the proliferation,migration,invasion and EMT of human breast cancer cell line MCF-7.Methods The expression of SNHG3 in breast cancer and breast cancer cell line MCF-7 was analyzed by bioinformatics and real-time fluores-cent quantitative PCR(RT-qPCR);RNAi technology was used to construct MCF-7 recombinant cell lines with knockdown SNHG3(siSNHG3)and control(siNC),and Western blot and cellular immunofluorescence were applied to detect autophagy markers;autophagosome lysosomal fusion inhibitor BafA1 or ear-ly autophagosome formation inhibitor 3-MA was employed to treat MCF-7 cells with or without SNHG3 knockdown,Western blot was used to detect the expression of LC3-Ⅱ or p62,and the effect on autophagic vesicle formation or autophagic degradation was observed;clone formation experiment,CCK8 experiment,wound healing experiment,and Transwell experiment were used to detect the effects of siSNHG3 combined or not combined with BafA1 or 3-MA on the proliferation,lateral migration,longitudi-nal migration,and invasion of MCF-7 cells.Western blot was used to detect its effect on the EMT of MCF-7 cells.Results Bioinformatics analysis and RT-qPCR confirmed that SNHG3 was highly expressed in breast cancer and breast cancer cell line MCF-7;Western blot and cellular immunofluorescence confirmed that knockdown of SNHG3 could activate autophagy in breast cancer;the clone formation,CCK-8,wound healing,and Tran-swell experiment confirmed that downregulation of SNHG3 ex-pression could inhibit tumor proliferation,migration,and inva-sion by activating autophagy;Western blot confirmed that SNHG3 promoted EMT process of breast cancer through negative regulation of autophagy.Conclusions SNHG3 is abnormally overexpressed in breast cancer and negatively regulates autoph-agy,and can enhance the proliferation,migration,invasion and EMT process of breast cancer cells through negatively regulating autophagy,suggesting that SNHG3 is a potential target for diag-nosis and treatment of breast cancer.

Gap junction(GJ),also known as gap junction,is widely found between neurons and glial cells,and can connect neighboring cells and mediate the transmission of electrical sig-nals between neighboring cells.The GJ channel,which exists between neurons and mediates intercellular electrical signaling,is also known as an electrical synapse.Connexins(Cxs)are the molecular basis of GJ,and are expressed to different degrees in different neurons and glial cells.The presence of GJ mediates different functions among neurons and glial cells,which further influences the establishment of various mature neural circuits,re-flecting the importance of GJ in the maintenance of neural cir-cuits.This review summarizes the relationship between GJ and neural circuits in relation to the effects of GJ and different Cxs on neurons and glial cells,providing new research ideas for the treatment of neuropsychiatric disorders.
