Lung cancer is the leading cause of cancer-related deaths worldwide. While modern medical therapies such as surgery， chemotherapy， and radiotherapy have achieved progress， they often come with severe side effects and drug resistance. Traditional Chinese medicine （TCM）， characterized by its multi-component， multi-target， and holistic regulatory properties， plays a significant role in the adjunctive treatment of lung cancer. It offers unique advantages in alleviating clinical symptoms， enhancing patients' quality of life， prolonging survival， and enhancing efficacy while reducing toxicity， serving as an important therapeutic modality for lung cancer. The theory of cancer-toxin pathogenesis proposes that phlegm-toxin is a key pathogenic factor in lung cancer， with phlegm-toxin mutual entanglement being the core pathogenesis of lung cancer. The pathogenic characteristics-viscosity， dispersion， and damage to the healthy Qi-of phlegm-toxin are closely related to the accumulation of acidic metabolic products， tumor invasion and metastasis， and immune suppression during the course of lung cancer. Phlegm resolving and toxin clearing are the core therapeutic methods for lung cancer. Such prescriptions possess dual functions of resolving phlegm and dissipating mass， as well as inhibiting tumor and detoxifying. They exert antitumor effects through multiple pathways， including regulating metabolic reprogramming of glucose and lipids， improving the acidic microenvironment of tumors， and inhibiting inflammatory signaling pathways. This paper systematically reviews the current clinical application status and mechanisms of phlegm-resolving and detoxifying Chinese herbal medicines. By integrating the theory of cancer-toxin pathogenesis with modern pharmacological research findings， this paper explores their application in lung cancer treatment and establishes a clinical application system for phlegm-resolving and detoxifying therapies in lung cancer based on phlegm-toxin pathogenesis. This system integrates ancient and modern experiences with contemporary mechanisms， aiming to provide theoretical foundations and practical references for integrated traditional and Western medicine diagnosis， treatment， and drug development for lung cancer and other conditions.

Objective: To analyze the factors affecting direct-acting antiviral (DAA) therapy among cases with hepatitis C virus (HCV) infection in Zhejiang Province, so as to provide evidence for optimizing local HCV prevention and treatment strategies and improving DAA treatment coverage. Methods: Eight counties (cities, districts) in Zhejiang Province were selected as survey sites. Consecutive sampling was used to enroll HCV cases reported from November 2022 to June 2024. Demographic information, diagnosis and treatment status, DAA therapy, and awareness of relevant medical insurance policies were collected through questionnaire surveys. Factors affecting DAA therapy among cases with HCV infection were analyzed using a multivariable logistic regression model. Results: A total of 412 questionnaires were distributed, and 404 valid questionnaires were collected, with an effective rate of 98.06%. There were 291 males (72.03%) and 113 females (27.97%). The median age was 49.00 (interquartile range, 11.00) years. A total of 303 cases received DAA therapy, with a proportion of 75.00%. Multivariable logistic regression analysis showed that HCV cases aged 40-<50 years (OR=3.469, 95%CI: 1.228-9.345) and with per capita monthly household income >3 000 yuan (>3 000-5 000 yuan, OR=3.198, 95%CI: 1.597-6.403; >5 000 yuan, OR=5.391, 95%CI: 2.230-13.033) had higher likelihood of receiving DAA therapy. HCV cases diagnosed in non-infectious disease departments (OR=0.334, 95%CI: 0.173-0.643), concerned about economic burden of DAA therapy (OR=0.309, 95%CI: 0.160-0.599), and unaware of HCV payment policy by disease type (OR=0.262, 95%CI: 0.111-0.622) had lower likelihood of receiving DAA therapy. Conclusions The proportion of DAA therapy among cases with HCV infection in Zhejiang Province is relatively high. Age, per capita monthly household income, department of diagnosis, concerns about DAA therapy, and medical insurance/payment policies are factors influencing DAA therapy among cases with HCV infection.

AIM:To appraise the bioequivalence and safety of the test preparation of ritonavir tab-lets and the reference preparation(trade name:Norvir?)in healthy adult subjects under fasting and postprandial conditions.METHODS:This study was a randomized,open-label,single-dose,four-period,fully repeated crossover design bioequivalence study protocol.Thirty-six healthy male and female volunteers were enrolled in the fasting and post-prandial conditions,and a single dose of the test preparation and reference preparation was orally administered.We used liquid chromatography-tan-dem mass spectrometry(LC-MS/MS)to finish the bioassay of the drug concentration of ritonavir in plasma.Pharmacokinetic parameters were statisti-cally analyzed using PhoenixWinNonlin8.1 software(Pharsight,USA)and a non-compartmental model.RESULTS:Under fasting conditions,the pharmacoki-netic parameters of the test and reference prepara-tions:Cmax(792.010±369.282)ng/mL and(856.939±394.427)ng/mL,AUC0-t(6 463.043±2 876.849)ng·mL-1·h and(6 907.690±3 046.132)ng·mL-1·h,AUC0-∞(6 603.617±2 916.352)ng·mL-1·h and(7 051.614±3 093.047)ng·mL-1·h.Here are the pharmacokinetic parameters for both the test prep-aration and the reference preparation in the post-prandial condition:Cmax(574.380±289.566)ng/mL and(615.796±297.382)ng/mL,AUC0-t(5 084.796±2 435.557)ng·mL-1·h and(5 414.167±2 416.952)ng·mL-1·h,AUC0-∞(5 219.144±2 487.793)ng·mL-1·h and(5 551.060±2 490.604)ng·mL-1·h.The 90%confidence interval of the geometric mean ratio of AUC0-t,AUC0-∞,and Cmax for the test preparation and reference preparation lied in the equivalent range of statistics.CONCLUSION:The tested preparation was bioequivalent to the reference preparation un-der fasting and postprandial conditions.

China has become the country with the highest global burden of heart failure(HF).Despite the widespread use of prognostic-improving medications today,the mortality rate of HF remains high,reaching 13.7％at one year-particularly among patients with heart failure with reduced ejection fraction(HFrEF).HF interventional device therapy(structural intervention)targets the structural factors underlying HF,including atrial pressure,ventricular remodeling,and valvular intervention.It leverages the heart's intrinsic physiological properties and pathological progression mechanisms to deliver treatments through interventions without external active forces,achieving anatomical or functional repair.This field has emerged as a rapidly growing area and plays an increasingly critical role in HF management.This article provides a comprehensive review and summary of the latest advancements in HF and cardiomyopathy interventional therapy over the past year.It covers various novel technologies and products currently in the research phase,aiming to provide an in-depth analysis of the current status and future directions of HF interventional therapy,and further advance the development of this discipline.

Indocyanine green(ICG)is one of the near-infrared fluorescent contrast agents approved for clinical use in fluorescence-guided surgery.Although widely applied,it still has some limitations.In recent years,various targeted fluorescent agents have been explored in pancreatic cancer patients;however,there is still no standardized consensus among surgeons regarding fluorescence-guided surgery for pancreatic cancer.In 2023,the first the international consensus report on fluorescent surgery navigation for pancreatic tumors was published,gathering perspectives from 38 pancreatic surgeons worldwide on current practices and future directions.A total of 76 statements were anonymously voted on using the Delphi method,resulting in 61 recommended statements.This consensus offers valuable guidance for the implementation of fluorescence-guided surgery in pancreatic tumor operations in China,yet its clinical application should be adapted in consideration of local expert opinions and patient-specific factors.This article interprets key aspects of the consensus,including the use of ICG,intraoperative fluorescence imaging techniques,and the fluorescence heterogeneity of pancreatic tumors,in combination with the authors'clinical experience,with the aim of providing reference and insight for the application of fluorescence-guided surgery in pancreatic tumors.

Objective:To investigate the clinical application value of a novel filter's retraction hook capture technique of pull-assisted method for the endovascular retrieval of conical inferior vena cava (IVC) filters whose hook attached to the wall.Methods:From January 2020 to December 2024, patients with conical filters whose hook attached to the wall admitted at Beijing Jishuitan Hospital were enrolled consecutively.Results:A total of 46 patients underwent filter retrieval using filter's retraction hook capture technique of pull-assisted method. Among these patients, 39 cases (84.8%) were successful in filter retrieval, with the penetration distance of cranial anchor vertex of 3.3(2.5, 4.4) mm, and 13 (33.3%) filters were deformed. The other 7 cases were unsuccessful, with a penetration distance of cranial anchor vertex of 5.0 (4.3, 5.0) mm, and 6 (85.7%) filters were deformed. There was a statistically significant difference between the two groups ( P<0.05). One case (2.2%) had IVC injury, one case (2.2%) experienced filter fracture, and no symptomatic pulmonary embolism occurred. Logistic regression analysis showed that filter deformation was an independent dangerous factor for filter's retraction. Conclusions:Filter's retraction hook capture technique of pull-assisted method is effective in removing conical filters whose hook attached to the wall, with no symptomatic PE occurring. This method can be considered as a new adjuvant technique for filter retrieval.

For middle-aged and elderly patients with conditions such as spinal fractures and degenerative spinal diseases, spinal internal fixation is a core surgical procedure for reconstructing spinal stability, heavily relying on the biomechanical stability provided by pedicle screw systems. Whereas, these patients are often complicated by osteoporosis that can significantly compromise the stability of the bone-pedicle screw interface, leading to a marked increase in pedicle screw loosening and surgical failure rates. The bone cement-augmented pedicle screw technique, which involves injecting bone cement into the vertebral body or screw trajectory to optimize the mechanical properties of the bone-pedicle screw composite, has been proven to significantly enhance fixation strength and effectively prevent screw-related failures, thereby reducing the incidence of internal fixation failure in high-risk populations undergoing spinal fusion. However, the widespread clinical application of this technique has faced challenges such as inaccurate clinical decision-making (indication and contraindication selection), non-standardized operative practices, and insufficient awareness of complication prevention, resulting in considerable variability in clinical outcomes and even severe complications. To address this, Prof. Luo Fei from First Affiliated Hospital of Army Medical University initiated the project and the Chinese Association Orthopaedic Surgeons organized relevant experts to develop the Evidence-based clinical practice guideline for bone cement-augmented pedicle screw technique ( version 2025), based on current evidence. The guidelines put forward 8 recommendations regarding the clinical value, scope of application, and operational standards of the technique, aiming to provide evidence-based medical support and technical standardization for clinical decision-making.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.
