Background: s/Aims: Non-invasive models stratifying clinically significant portal hypertension (CSPH) are limited. Herein, we developed a new non-invasive model for predicting CSPH in patients with compensated cirrhosis and investigated whether carvedilol can prevent hepatic decompensation in patients with high-risk CSPH stratified using the new model. Methods: Non-invasive risk factors of CSPH were identified via systematic review and meta-analysis of studies involving patients with hepatic venous pressure gradient (HVPG). A new non-invasive model was validated for various performance aspects in three cohorts, i.e., a multicenter HVPG cohort, a follow-up cohort, and a carvediloltreating cohort. Results: In the meta-analysis with six studies (n=819), liver stiffness measurement and platelet count were identified as independent risk factors for CSPH and were used to develop the new “CSPH risk” model. In the HVPG cohort (n=151), the new model accurately predicted CSPH with cutoff values of 0 and –0.68 for ruling in and out CSPH, respectively. In the follow-up cohort (n=1,102), the cumulative incidences of decompensation events significantly differed using the cutoff values of <–0.68 (low-risk), –0.68 to 0 (medium-risk), and >0 (high-risk). In the carvediloltreated cohort, patients with high-risk CSPH treated with carvedilol (n=81) had lower rates of decompensation events than non-selective beta-blockers untreated patients with high-risk CSPH (n=613 before propensity score matching [PSM], n=162 after PSM). Conclusions Treatment with carvedilol significantly reduces the risk of hepatic decompensation in patients with high-risk CSPH stratified by the new model.

Following the core outcome set standards for development(COS-STAD), this study aims to construct core outcome set(COS) for clinical research on traditional Chinese medicine(TCM) treatment of simple obesity. Firstly, a comprehensive review was conducted on the randomized controlled trial(RCT) and systematic review(SR) about TCM treatment of simple obesity that were published in Chinese and English databases to collect reported outcomes. Additional outcomes were obtained through semi-structured interviews with patients and open-ended questionnaire surveys for clinicians. All the collected outcomes were then merged and organized as an initial outcome pool, and then a preliminary list of outcomes was formed after discussion by the working group. Subsequently, two rounds of Delphi surveys were conducted with clinicians, methodology experts, and patients to score the importance of outcomes in the list. Finally, a consensus meeting was held to establish the COS for clinical research on TCM treatment of simple obesity. A total of 221 RCTs and 12 SRs were included, and after integration of supplementary outcomes, an initial outcome pool of 141 outcomes were formed. Following discussions in the steering advisory group meeting, a preliminary list of 33 outcomes was finalized, encompassing 9 domains. Through two rounds of Delphi surveys and a consensus meeting, the final COS for clinical research on TCM treatment of simple obesity was determined to include 8 outcomes: TCM symptom scores, body mass index(BMI), waist-hip ratio, waist circumference, visceral fat index, body fat rate, quality of life, and safety, which were classified into 4 domains: TCM-related outcomes, anthropometric measurements, quality of life, and safety. This study has preliminarily established a COS for clinical research on TCM treatment of simple obesity. It helps reduce the heterogeneity in the selection and reporting of outcomes in similar clinical studies, thereby improving the comparability of research results and the feasibility of meta-analysis and providing higher-level evidence support for clinical practice.

Objective To investigate the changes of diameter of the main trunk of the extracranial segment of the facial nerve,local hemodynamics and facial muscle thickness in patients with peripheral facial palsy(PFP)at acute stage by high frequency ultrasound(HFUS).Methods Sixty patients with acute PFP were enrolled as the PFP group,and 30 healthy people were selected as the control group.The following facial param-eters were scanned and recorded using HFUS:diameter of the main trunk of the extracranial segment of the facial nerve(FN-d),facial artery diameter(FA-d),facial artery systolic velocity(FA-Vs),facial artery diastolic velocity(FA-Vd),facial artery resistance index(FA-RI),frontalis muscle thickness(FM-t),depressor anguli oris muscle thickness(DAO-t),and depressor labii inferioris muscle thickness(DLI-t).The feasibility of facial param-eters in the diagnosis of acute-phase peripheral facial palsy(PFP)was evaluated,with intra-group and inter-group variability comparisons performed.Pearson correlation analysis was conducted to evaluate the relationship between acute-phase facial parameters and House-Brackmann(H-B)scale scores in PFP patients.Results(1)The H-B score of the PFP group was significantly lower than that of the control group,and the difference was statistically significant(P＜0.05).(2)The reliability of repeated measurements of facial parameters by different testers is good(ICC＞0.75).(3)The FN-d and FA-RI values on the affected side of PFP group were higher than those on the healthy side and control group,and FA-Vs,FA-Vd,DAO-t and DLI-t values were lower than those on the healthy side and control group,with statistical significance(P＜0.05).(4)The FN-d and FA-RI values of the affected side in the PFP group were negatively correlated with the H-S scale score(r=-0.847,P＜0.05;r=-0.863,P＜0.05);FA Vs,FA Vd,DAO-t,DLI-t are positively correlated with H-S scale scores(r=0.808,P＜0.05;r=0.757,P＜0.05;r=0.836,P＜0.05;r=0.694,P＜0.05).Conclusions HFUS can effectively detect the characteristic changes such as the increase in the diameter of the extrcranial facial nerve trunk,local microcircula-tion disturbance and facial muscle atrophy in patients with PFP in the acute stage,and the increase and decrease of FN-d,FA Vs,FA Vd,FA-RI,DAO-t,and DLI-t can accurately reflect the improvement or progress of PFP,which has important guiding significance for clinical disease monitoring and efficacy evaluation.

OBJECTIVES: To evaluate the inhibitory effect of Macrothele raveni crude venom against proliferation of different cancer cells and identify the active components in the venom. METHODS: Different cancer cell lines were treated with different concentrations of Macrothele raveni venom for 48 h, and cell proliferation and the half-maximal inhibitory concentrations (IC₅₀) of the venom were assessed with CCK-8 assay. The apoptosis rate of breast cancer MCF7 cells following the treatment was analyzed with flow cytometry, and the changes in cellular caspase-8 and caspase-9 expressions were detected. The crude venom was separated into protein, peptide, and small-molecule compound fractions using gel filtration chromatography and high-performance liquid chromatography (HPLC). The protein and peptide components were identified using proteomics analysis, and small-molecule compounds were structurally characterized using nuclear magnetic resonance (NMR), mass spectrometry (MS), and HPLC. RESULTS The crude venom exhibited strong concentration-dependent inhibitory effects on proliferation of MCF7 cells and nasopharyngeal carcinoma SUNE1 and HONE1 cells (IC₅₀ of 2.14±0.29, 1.57±0.14, and 2.85±0.15 µg/mL, respectively), with less potent inhibitory effects in gastric cancer HGC27 cells and colorectal cancer SW620 cells (IC₅₀ of 3.02±0.27 and 3.02±0.28 µg/mL, respectively). The crude venom significantly promoted MCF7 cell apoptosis likely via the caspase 8 signaling pathway. The protein fraction from the crude venom showed a weak inhibitory effect in MCF7 cells, whereas the peptide fraction exhibited a much stronger inhibitory effect (IC₅₀ of 6.41±0.31 µg/mL). The peptides in the peptide fraction, with relative molecular mass around 10 000, were homologous to those found in Macrothele gigas venom. The small-molecule fraction consisted mainly of nucleotide metabolites without obvious inhibitory effects in MCF7 cells, but its combination with the peptide fraction showed significantly enhanced inhibitory activity. Conclusion The inhibitory effects of Macrothele raveni venom, which vary significantly across different cancer cell lines, are attributed primarily to its peptide components, which may act synergistically with the nucleotide metabolites.

Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.

OBJECTIVE: Therapeutic angiogenesis has become a promising approach for treating ischemic heart disease (IHD). The present study aims to investigate the effects of Qishen Granule (QSG) on angiogenesis in myocardial ischemia (MI) and the potential mechanism. METHODS: In vivo study was conducted on rat model of myocardial infarction. QSG was performed daily at a dose of 2.352 g/kg for four weeks. Cardiac function was assessed by echocardiogram and pro-angiogenic effects were evaluated by Laser Doppler and CD31 expression. Oxygen-glucose deprivation (OGD) was applied in cultured human umbilical vein endothelial cells (HUVECs). Cell viability, wound healing and tube formation assay were used to test functions of HUVECs. ELISA and Western blots were used to assess protein expressions of bone morphogenetic protein 2-delta-like 4-notch homolog 1 (BMP2-Dll4-Notch1) signaling pathway. RESULTS: The results showed that QSG improved heart function, cardiac blood flow and microvessel density in myocardial ischemic rats. In vitro, QSG protected HUVECs by promoting the cell viability and tube formation. QSG upregulated bone morphogenetic protein-2 (BMP2) and downregulated delta-like 4 (Dll4) and notch homolog 1 (Notch1) expressions both in rats and HUVECs. CONCLUSION QSG protected against MI by promoting angiogenesis through BMP2-Dll4-Notch1 pathway. BMP2 might be a promising therapeutic target for IHD.

Congenital orofacial cleft, the most common birth defect in the maxillofacial region, exhibits a wide range of prognosis depending on the severity of deformity and underlying etiology. Non-syndromic congenital orofacial clefts typically present with milder deformities and more favorable treatment outcomes, whereas syndromic congenital orofacial clefts often manifest with concomitant organ abnormalities, which pose greater challenges for treatment and result in poorer prognosis. This consensus provides an elaborate classification system for varying degrees of orofacial clefts along with corresponding diagnostic and therapeutic guidelines. Results serve as a crucial resource for families to navigate prenatal screening results or make informed decisions regarding treatment options while also contributing significantly to preventing serious birth defects within the development of population.
