ObjectiveTo systematically characterize the in vitro chemical constituents of Entada phaseoloides and its absorbed prototype compounds and metabolites in a neuropathic pain (NP) model, thereby elucidating the potential pharmacological material basis underlying its analgesic activity. MethodsUltra-high-performance liquid chromatography coupled with quadrupole-Orbitrap high-resolution mass spectrometry (UHPLC-Q-Orbitrap HRMS) was used to analyze the constituents of the 80% methanol extract of E. phaseoloides. Thirty-six mice were divided into a blank group, low-, medium-, and high-dose E. phaseoloides extract groups (25, 50, and 100 mg·kg-1, respectively), an aspirin group (400 mg·kg-1), and a morphine group (10 mg·kg-1), with six mice in each group. The tail-flick threshold was measured. Twenty-four mice were randomly divided into a blank group and low-, medium-, and high-dose E. phaseoloides extract groups (25, 50, and 100 mg·kg-1, respectively), with six mice in each group, and motor coordination was evaluated. A spinal nerve ligation (SNL) model was established in mice. Twenty-four mice were randomly divided into a sham-operated (Sham) group, an SNL group, an SNL + E. phaseoloides extract group (750 mg·kg-1), and an SNL + pregabalin group (20 mg·kg-1), with 6 mice in each group. Mechanical allodynia and thermal hyperalgesia were evaluated. Behavioral assessments were combined to determine the optimal onset time of the analgesic effect, and plasma samples were collected at this time point. Absorbed components and metabolites were systematically identified based on accurate mass, MS/MS fragmentation patterns, retention time, and comparisons with literature data and reference standards. Meanwhile, network pharmacology, target similarity analysis, and molecular docking validation were integrated to evaluate the potential effects of absorbed components on disease intervention. ResultsCompared with the blank group, the high-dose E. phaseoloides extract group and morphine group showed significantly increased pain response thresholds (P<0.01), without affecting motor coordination in normal mice. Compared with the Sham group, the SNL group exhibited significantly decreased thresholds for mechanical allodynia and thermal hyperalgesia (P<0.01). Compared with the SNL group, the SNL + E. phaseoloides extract group and SNL + pregabalin group showed significantly increased thresholds for mechanical allodynia and thermal hyperalgesia (P<0.01). The analgesic effect of E. phaseoloides was most significant at 2 h after administration. A total of 70 constituents were identified in vitro, and 22 prototype compounds and 29 metabolites were detected in plasma. The targets of the absorbed components were mainly enriched in biological processes associated with pain signal perception and transmission and showed a high degree of overlap with disease genes related to neuropathic pain. In addition, multiple components exhibited strong binding energies with core pain-related targets. Based on integrated analysis of in vitro content, plasma exposure levels, and target associations, ketanthamide A-β-D-pyranoside and ketengzide were identified as the most representative pharmacologically active substances responsible for the analgesic effect. ConclusionThis study systematically elucidates the material basis of E. phaseoloides intervention in neuropathic pain from three aspects, including chemical constituent characteristics, in vivo behavioral characteristics, and potential targets, providing important theoretical foundations and experimental support for further studies on its pharmacological mechanism and analgesic drug development.

Objective: To compare the biological characteristics of human induced pluripotent stem cell-derived platelet exosomes (hiPSC-Plt-Exos) with those of conventional apheresis platelet exosomes (Plt-Exos), specifically focusing on their differential abilities to enhance the proliferation and migration of human umbilical cord mesenchymal stem cells (hUC-MSCs). Methods: Exosomes were isolated from hiPSC-derived Plt and apheresis Plt concentrate using size exclusion chromatography. These exosomes were then characterized through nanoparticle tracking analysis (NTA), transmission electron microscopy (TEM), and Western blotting. Co-culture experiments into hUC-MSCs were conducted with hiPSC-Plt-Exos and apheresis Plt-Exos, respectively. Their effects on the proliferation and migration of hUC-MSCs were assessed via cell proliferation assays and scratch tests. Results: hiPSC-Plt-Exos and apheresis Plt-Exos exhibited comparable particle sizes, morphological features (such as the characteristic cup-shaped structure), and surface markers (including CD9 and HSP70). Notably, hiPSC-Plt-Exos demonstrated a significantly greater ability to enhance the proliferation and migration of hUC-MSCs compared to apheresis Plt-Exos (P<0.05). These differences provide critical comparative data for their application in various clinical contexts. Conclusion: This study establishes a theoretical foundation for developing precise therapeutic strategies based on hiPSC-Plt-Exos. Furthermore, it underscores the necessity of selecting the appropriate type of exosomes according to the specific disease microenvironment to achieve optimal therapeutic outcomes.

Metformin has been demonstrated to attenuate hyperglycaemia by modulating the gut microbiota. However, the mechanisms through which the microbiome mediates metformin monotherapy failure (MMF) are unclear. Herein, in a prospective clinical cohort study of newly diagnosed type 2 diabetes mellitus (T2DM) patients treated with metformin monotherapy, metagenomic sequencing of faecal samples revealed that Phocaeicola vulgatus abundance was approximately 12 times higher in nonresponders than in responders. P. vulgatus rapidly hydrolysed taurine-conjugated bile acids, leading to ceramide accumulation and reversing the improvements in glucose intolerance conferred by metformin in high-fat diet-fed mice. Interestingly, C22:0 ceramide bound to mitochondrial fission factor to induce mitochondrial fragmentation and impair hepatic oxidative phosphorylation in P. vulgatus-colonized hyperglycaemic mice, which could be exacerbated by metformin. This work suggests that metformin may be unsuitable for P. vulgatus-rich T2DM patients and that clinicians should be aware of metformin toxicity to mitochondria. Suppressing P. vulgatus growth with cefaclor or improving mitochondrial function using adenosylcobalamin may represent simple, safe, effective therapeutic strategies for addressing MMF.

With the growing emphasis on maternal and child oral health, the significance of managing oral health across preconception, pregnancy, and infancy stages has become increasingly apparent. Oral health challenges extend beyond affecting maternal well-being, exerting profound influences on fetal and neonatal oral development as well as immune system maturation. This expert consensus paper, developed using a modified Delphi method, reviews current research and provides recommendations on maternal and child oral health management. It underscores the critical role of comprehensive oral assessments prior to conception, diligent oral health management throughout pregnancy, and meticulous oral hygiene practices during infancy. Effective strategies should be seamlessly integrated across the life course, encompassing preconception oral assessments, systematic dental care during pregnancy, and routine infant oral hygiene. Collaborative efforts among pediatric dentists, maternal and child health workers, and obstetricians are crucial to improving outcomes and fostering clinical research, contributing to evidence-based health management strategies.

Objective:To investigate the impact of evaluating the alcohol intake on all-cause mortality in patients with metabolic-associated fatty liver disease(MAFLD)and metabolic dysfunction and alcohol-related liver disease(MetALD).Method:The retrospective study included patients aged 20 to 74 years with hepatic steatosis diagnosed by ultrasound,with data from the Third National Health and Nutrition Examination Survey(NHANES III)between 1988 and 1994. Participants were categorized into light,moderate,and heavy drinking groups according to daily alcohol intake. Multivariable-adjusted hazard ratios(aHR)and their 95% confidence intervals( CI)were calculated by Cox proportional risk regression modeling to assess the effect of alcohol intake on all-cause mortality. Results:A total of 2 322 patients were included in the study. Males accounted for 50.2%(1 166/2 322),with a age of 42.0(31.3,57.0)years,a median follow-up of 316.0(270.0,337.0)months,and an all-cause mortality rate of 1.48% per person-year. There were 1,763 cases in the light drinking group,333 in the moderate drinking group,and 226 in the heavy drinking group.The all-cause mortality rates for patients in the three drinking groups were 1.38%,1.67%,and 2.10% per person-year,respectively. The moderate(a HR=1.37,95% CI:1.12 to 1.67, P=0.002)and heavy(a HR=1.45,95% CI:1.17 to 1.80, P=0.001)drinking groups were independently associated with increased all-cause mortality following covariate adjustment. There was a difference in all-cause mortality for alcohol intake in non-type 2 diabetes mellitus(T2DM)patients under 60 years of age( P<0.05),but the difference was not statistically significant between non-T2DM patients over 60 years of age and T2DM patients of all ages( P>0.05)according to the analysis of diabetes status and age subgroups. Conclusion:Alcohol intake has a dose-dependent negative effect on patients with MAFLD and MetALD. The risk of all-cause mortality increased significantly with increasing alcohol intake.

Cancer stands as a significant global public health challenge, and cancer screening serves as a pivotal strategy for reducing its mortality. Presently, only a limited number of cancer types have appropriate screening methods available. Traditional single-cancer screening approaches are fraught with limitations, including invasiveness, low accuracy, and poor patient compliance. Multi-cancer early detection (MCED) leveraging liquid biopsy technology enables non-invasive and efficient early detection of multiple cancers by analyzing biomarkers such as cell-free DNA, cell-free RNA, proteins, and metabolites in blood and other bodily fluids. This innovative approach substantially broadens the spectrum of detectable cancers and enhances population coverage, showcasing immense potential for improving existing cancer screening strategies. This expert consensus comprehensively reviews the progress of liquid biopsy-based MCED, biomarker selection and detection technologies, the criteria for cancer type selection, research design and clinical utility evaluation, as well as implementation pathways. The overarching goal of this consensus is to offer scientific guidance for further research and the widespread adoption of MCED, thereby facilitating the continuous optimization of cancer screening strategies.
