Objective Orosomucoid1 （ORM1） is a novel target in the quest for anti-fatigue pharmacotherapy. Preliminary investigations have illuminated oleuropein （OLE） as a promising candidate molecule, poised to enhance ORM1 expression. To elucidate the influence of OLE on ORM1 protein expression and assess its ramifications on muscle endurance. Methods The impact of OLE on ORM1 protein expressions within hepatocytes and liver tissue was meticulously quantified through Western blotting; the effects of OLE on muscle endurance were evaluated via the rotarod and forced swimming tests; glycogen content within liver and muscle tissues was determined utilizing a specialized kit; and PAS staining was employed to visualize glycogen deposition in the gastrocnemius muscle. Results OLE demonstrated a capacity to elevate ORM1 protein expression in hepatocytes in a time- and dose-dependent manner, concurrently prolonging the duration of swimming and rotarod performance in mice, also in a time- and dose-dependent manner. Furthermore, OLE augmented ORM1 expression in liver tissue, elevated serum ORM1 levels, and enhanced glycogen reserves within the liver and muscle. Conclusion OLE may serve to amplify muscle endurance by elevating ORM1 levels in vivo and augmenting glycogen stores within skeletal muscle.

Objective: Patients with atherosclerotic cardiovascular disease (ASCVD) following percutaneous coronary intervention (PCI) are classified as very-high-risk individuals in cardiovascular disease (CVD) risk stratification. The distribution pattern of traditional Chinese medicine (TCM) syndromes in this patient population, as well as its association with blood lipid profiles and clinical prognosis, remains unclear. The present prospective cohort study aims to investigate these correlations, thereby providing insights to enrich the research fields. Methods: We enrolled consecutive patients with ASCVD who underwent PCI at the Integrated Cardiology Unit of China-Japan Friendship Hospital between September 1, 2020 and December 31, 2022. Demographics and clinical characteristics, signs and symptoms defining each TCM syndrome, and fasting venous blood samples were collected at baseline and follow up or upon major adverse cardiovascular events (MACEs). We analyzed the correlation between TCM syndromes, blood lipid profiles, and MACEs, and developed a new joint prognostic model incorporating both TCM syndromes and blood lipids using logistic regression. The analyses were based on detailed baseline and one-year follow-up data. Results: A per-protocol analysis was performed on 586 patients with complete data ultimately. During the one-year follow-up, 174 patients (29.69%) experienced a MACE. We performed statistical analyses on comorbidities, medication, and biochemical indicators across groups defined by TCM syndrome differentiation. When comparing different TCM syndromes, no significant differences were found in age, body mass index (BMI), history of revascularization, comorbidities, family history of CVD, smoking or drinking, or statin intensity (P > 0.05). Patients with intertwined phlegm and blood stasis syndrome exhibited significantly higher levels of total cholesterol (TC, 5.27 ± 1.18 mmol/L, P < 0.001), triglyceride (TG, 1.96 ± 1.33 mmol/L, P = 0.008), low-density lipoprotein cholesterol (LDL-C, 3.35 ± 0.79 mmol/L, P < 0.001), and high-density lipoprotein cholesterol (HDL-C, 1.24 ± 0.81 mmol/L, P < 0.001) compared with those with other TCM syndromes combined. A multivariable logistic regression model was constructed to predict MACEs. The model included TCM syndrome type [with intertwined phlegm and blood stasis as a predictor, adjusted odds ratio (OR) = 1.413, 95% confidence interval (CI): 0.517 – 3.864, P = 0.501], age (adjusted OR = 0.97, 95% CI: 0.955 – 1.001, P = 0.057), male gender (adjusted OR = 0.698, 95% CI: 0.416 – 1.170, P = 0.173), TC (adjusted OR = 1.004, 95% CI: 0.513 – 1.965, P = 0.990), and LDL-C (adjusted OR = 5.825, 95% CI: 2.214 – 15.326, P < 0.001). This model demonstrated good discriminatory ability for MACEs in post-PCI ASCVD patients [the area under the receiver operating characteristic (ROC) curve (AUC) = 0.865, 95% CI: 0.816 – 0.914]. Conclusion The intertwined phlegm and blood stasis TCM syndrome is associated with a distinct atherogenic lipid profile characterized by elevated levels of TC and LDL-C. The prognostic model that incorporates this TCM syndrome type along with conventional lipid parameters (TC and LDL-C) shows good discriminatory ability for predicting MACEs in ASCVD patients after PCI, underscoring the potential clinical utility of integrating TCM syndrome differentiation into CVD risk assessment.

Background: and Purpose In patients with large vessel occlusion (LVO), intravenous thrombolysis (IVT) frequently alters thrombus location; however, the clinical impact of this phenomenon remains unclear. We aimed to compare post-IVT thrombus dynamics between tenecteplase and alteplase and to evaluate the association between thrombus dynamics and 3-month outcomes. Methods: This retrospective study analyzed prospectively collected, multicenter data from consecutive patients with LVO who underwent bridging therapy between January 2022 and December 2024. Thrombus dynamics were classified as resolution, migration, or stability. Analyses incorporated propensity score matching with weighting to balance baseline characteristics. Results: Of the 806 initially included patients, 746 were included after matching (373 treated with tenecteplase and 373 treated with alteplase). The incidence of thrombus migration was significantly higher in the tenecteplase group than in the alteplase group (19.3% vs. 11.3%; odds ratio [OR]: 1.92; 95% confidence interval [CI] 1.27–2.91). The advantage of tenecteplase over alteplase was restricted to patients with an IVT-to-puncture time of <60 minutes (18.6% vs. 6.2%; p=0.001) and was no longer significant when the interval ≥60 minutes (19.7% vs. 15.0%; p=0.204; pinteraction=0.043). Additionally, thrombus migration was associated with a better functional outcome (OR: 1.62; 95% CI 1.04–2.53). Finally, tenecteplase was associated with improved functional independence compared with alteplase (OR: 1.43; 95% CI 1.04–1.95). Conclusions Tenecteplase demonstrated superior efficacy in inducing thrombus migration compared with alteplase, particularly within 60 minutes of IVT administration. Thrombus migration independently predicted improved functional independence. These findings support the preferential use of tenecteplase for bridging therapy in patients with LVO.

Lung cancer constitutes the most prevalent and lethal malignant tumor in China. Approximately 85% of lung cancer diagnoses correspond to the non-small cell histological subtype [non-small cell lung cancer (NSCLC)]. Despite surgery being the mainstay for early-stage disease, postoperative recurrence remains high and adjuvant chemotherapy offers limited benefit. In recent years, targeted therapy has demonstrated substantial advantages in driver mutation-positive NSCLC. To this end, the Lung Cancer Medical Education Committee of the Chinese Medical Education Association developed guidelines based on a systematic review of evidence through November 2025, using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach and a modified Delphi method. Focusing on epidermal growth factor receptor (EGFR) and anaplastic lymphoma kinase (ALK), and addressing ROS proto-oncogene 1 (ROS1), B-Raf proto-oncogene serine/threonine kinase (BRAF) V600E mutation, and mesenchymal-epithelial transition factor (MET) exon 14 (METex14) skipping, the guideline covers molecular testing, neoadjuvant/adjuvant therapy, perioperative strategies, minimal residual disease monitoring, and postoperative surveillance. It defines testing requirements, specifies stage-directed and subtype-specific treatments, and standardizes minimal residual disease monitoring. These recommendations emphasize precision and feasibility to improve survival and quality of life.

Objective To evaluate the efficacy of minimally invasive neuroendoscopy combined with intraventricular drainage in the treatment of intraventricular hemorrhage.Methods A retrospective analysis was conducted on the clinical data of 88 patients with intraventricular hemorrhage who underwent surgical treatment from January 2018 to December 2023.All patients received bilateral ventricular indwelling external drainage tubes.Among them,37 cases were included in the endoscopy group.The bleeding side or side with more blood accumulation underwent a midline fistula.With the assistance of neuroendoscopy,the intraventricular blood clots were removed and a ventricular drainage tube was inserted.The contralateral ventricle was punctured and a ventricular drainage tube was inserted;The remaining 51 cases were included in the drainage group,in which bilateral ventricular drainage tubes were placed according to the traditional intraventricular drainage protocol.Results There was no significant statistical difference(P>0.05)between the endoscopic group and the drainage group in terms of mortality rate(10.8%vs.13.7%),rebleeding rate(8.1%vs.11.8%,P=0.576),intracranial infection rate(10.8%vs.17.6%,P=0.372),and hydrocephalus rate(10.8%vs.23.5%,P=0.166).Similarly,no significant statistical difference was found in the total hospitalization cost between the endoscopy group and the drainage group[(90700±73000)yuan vs.(99500±66000)yuan]and the GOS score during the 6-month follow-up(3.16±1.14 vs 3.02±1.12)showed(P>0.05).However,the postoperative GCS score improvement was significantly better in the endoscopic group than in the drainage group[2.00(2.00,4.00)vs.1.00(0.00,3.00),P=0.002].The duration of the extracranial drainage catheter placement was significantly shorter in the endoscopic group than in the drainage group[(7.16±2.99)days vs.(10.12±3.93)days,P<0.001].Conclusion Neuroendoscopy-assisted evacuation of intraventricular hemorrhage facilitates effective hematoma clearance,reduces the duration of ventricular drainage catheterization,and may contribute to improved patient outcomes.

Objective:To explore the effect of combining resistance training with stem cell transplantation on vascular remodeling after myocardial infarction, so as to provide a theoretical basis and treatment for clinical use.Methods:Seventy-five Sprague-Dawley rats were randomly divided into a sham operation group, a model group, a stem cell group, and a training and model combination group. All except the sham operation group underwent myocardial infarction modeling by ligation of the left anterior descending coronary artery. The stem cell group then received transplanted bone marrow mesenchymal stem cells (MSCs) and the training group performed weight-bearing ladder training. The combination group was given both interventions. The experiments lasted 8 weeks. At the end of the final exercise session, cardiac structure and functioning and myocardial blood flow were assessed using color Doppler ultrasound. Any pathological changes were observed through HE and Masson staining. Capillary density in the heart was determined via CD31 immunohistochemical staining. The expression levels of vascular endothelial growth factor (VEGF), CD31, α-smooth muscle actin (α-SMA), and endothelial nitric oxide synthase (eNOS) proteins were measured using western blotting.Results:Compared with the model group, cardiac structure and function showed significant improvement in the stem cell, training and combination groups. This was manifested as decreased end-diastolic diameter and end-systolic diameter in the left ventricle, along with increased left ventricular ejection fraction, left ventricular fraction shortening, the ratio of early to late diastolic filling velocity, and myocardial blood flow. Histological examination revealed a significant increase in capillary density, reduced collagen area, and less pathological hypertrophy of cardiomyocytes in the stem cell, training and combination groups. In those groups there was also upregulation of angiogenesis-related cytokines (VEGF, CD31, α-SMA and p-eNOS). Notably, all these improvements were particularly pronounced in the combination group.Conclusion:Resistance training combined with stem cell transplantation effectively improves vascular remodeling and enhances cardiac function after a myocardial infarction, at least in rats. The combination is more effective than either intervention alone.

Objective:To establish a method for determination of fluoride in water using a fully automated biochemical analyzer (abbreviated as this method).Methods:Based on the parameters of the fully automatic biochemical analyzer, appropriate reagent volumes and reaction time were optimized to determine fluoride ions in water within the standard curve range (0.0 - 2.0 mg/L). The method was validated through evaluation of linear range, detection limit, precision, accuracy, and comparative analysis with the manual measurement results of fluoride reagent spectrophotometric method specified in the "Standard Examination Methods for Drinking Water - Part 5: Inorganic Nonmetallic indices" (GB/T 5750.5-2023).Results:Within the range of 0.0 - 2.0 mg/L fluoride mass concentration, the absolute values of the correlation coefficients were > 0.999 0 and the detection limit of this method was 0.082 mg/L. The relative standard deviation for the determination of fluoride level in water samples with low, medium and high fluoride mass concentrations was 4.03%, 2.16% and 1.68%, respectively. The spiked recovery rates were 98.1%, 99.5%, and 100.2%, respectively. There was no statistically significant difference between the results obtained by this method and manual measurement ( t = 1.07, P = 0.295). Conclusion:This method exhibits high sensitivity, accuracy, and efficiency in detecting fluoride, enabling rapid sample detection through instrumental automation instead of manual operation.

Objective:To study the anti-inflammatory and protective effects of electroacupuncture on rats with cardiopulmo-nary resuscitation based on cholinergic anti-inflammatory pathway(CAP).Methods:Sixty male SD rats were randomly divided into sham operation group(Sham group),cardiopulmonary resuscitation group,electroacupuncture group,antagonist of α7-nicotinic ace-tylcholine receptor(α7nAChR)α Bungarus toxin group(αBGT group,1 μg/kg)and agonist of α7nAChR 3-(2,4-dimethoxybenzyli-dene)anabaseine(GTS-21)group(5 mg/kg),with 12 rats in each group.Model of cardiac arrest was established by inducing ventric-ular fibrillation in rats with percutaneous epicardial electrical stimulation,and routine resuscitation was performed,the defibrillation times,cardiopulmonary resuscitation duration and 72 h survival rate of rats in each group were observed and recorded.Neurological damage of rats in each group was scored(NDS score).Levels of inflammatory factors TNF-α,IL-1β and IL-6 in serum,heart,lung and brain of rats were measured by ELISA.HE staining was applied to evaluate the degree of tissue damage of heart,lung and brain tis-sues of rats in each group.Expressions of α7nAChR,NF-κB/MAPKs signal pathway related proteins in heart,lung and brain of rats in each group were detected by Western blot.Results:Compared with Sham group,the number of defibrillations,duration of cardiopul-monary resuscitation,NDS score,levels of TNF-α,IL-1β and IL-6 in serum,heart,lung and brain tissues,and NF-κB p65 protein in heart,lung and brain tissues in cardiopulmonary resuscitation group increased greatly(P<0.05),the 72 h survival rate,phosphory-lation levels of α7nAChR protein,ERK1/2,JNK and p38MAPK in heart,lung and brain tissues decreased greatly after restoration of spontaneous circulation(P<0.05),cells and neurons in the CA1 region of heart,lung and hippocampus were severely damaged.Com-pared with cardiopulmonary resuscitation group,change trend of relevant indicators in electroacupuncture group was opposite to the above,damage of cells and neurons in rat heart,lung and brain tissue was reduced(P<0.05).αBGT reduced the anti-inflammatory effect of electroacupuncture on cardiopulmonary resuscitation rats(P<0.05).GTS-21 enhanced the anti-inflammatory protection of electroacupuncture on cardiopulmonary resuscitation rats(P<0.05).Conclusion:Electroacupuncture has anti-inflammatory and pro-tective effects on cardiopulmonary resuscitation rats based on CAP,and NF-κB/MAPKs participate in α7nAChR mediated CAP.
