To thoroughly implement the strategic deployment outlined in the Opinions of the Central Committee of the Communist Party of China and the State Council on Promoting the Inheritance and Innovative Development of Traditional Chinese Medicine regarding research on dominant diseases of traditional Chinese medicine and to uphold the development philosophy of equal emphasis on traditional Chinese medicine and western medicine，the China Association of Chinese Medicine has fully played a leading academic role by systematically organizing and conducting a series of academic youth salons on clinical dominant diseases of traditional Chinese medicine. On September 13，2024，the 36^th Youth Salon on Clinical Dominant Diseases was successfully held in Nanjing，focusing on the advantages of traditional Chinese medicine and the integrative traditional Chinese medicine and western medicine in the diagnosis and treatment of erectile dysfunction （ED）. The conference brought together leading experts from traditional Chinese medicine，western medicine，and interdisciplinary fields，facilitating in-depth multidisciplinary discussions that led to key consensus on optimizing traditional Chinese medicine treatment protocols for ED，researching and developing new drugs of traditional Chinese medicine，and advancing interdisciplinary development in traditional Chinese medicine. This salon systematically sorted out the clinical strengths and distinctive features of traditional Chinese medicine in the diagnosis and treatment of ED. Based on current research foundations and clinical needs，it identified key directions for future scientific layout and scientific research tackling： （1） Standardization of syndrome differentiation system of traditional Chinese medicine for ED. （2） Optimization and standardization of intervention methods of integrated traditional Chinese medicine and western medicine. （3） High-quality clinical research guided by evidence-based medicine. （4） In-depth analysis of the pharmacological mechanisms of traditional Chinese medicine in the treatment of ED. （5） Clinical translation and application promotion of new drugs of traditional Chinese medicine. （6） Interdisciplinary integration and innovation in traditional Chinese medicine. For each research direction，key focus areas，expected objectives，and clinical value were further refined，along with the establishment of a scientifically sound priority funding level evaluation system. Therefore，building on the series of salons on the ED-focused dominant diseases of traditional Chinese medicine，this paper provides standardized guidance for clinical practice of traditional Chinese medicine in ED management，effectively contributing to the high-quality development of traditional Chinese medicine. It serves as a valuable reference for national scientific and technological strategic layout， research and development decision-making in new drugs of traditional Chinese medicine，research topic planning，and clinical guideline formulation.

Objective To systematically analyze the disease burden, long-term trends, and age-sex distribution of major valvular heart disease (VHD) subtypes—rheumatic heart disease (RHD), non-rheumatic valvular disease (NRVD), and non-rheumatic calcific aortic valve disease (CAVD)—in global, Chinese, and US populations from 1990 to 2021, providing evidence for public health strategies and clinical resource allocation. Methods Based on publicly available data from the Global Burden of Disease (GBD) Study 2021, we extracted incidence, mortality, and disability-adjusted life years (DALYs) for VHD from 1990 to 2021. Age-standardized rates (ASRs) were calculated using the GBD 2021 global standard population, and the estimated annual percentage change (EAPC) with its 95% uncertainty interval (UI) was computed for the period. Data from the Agency for Healthcare Research and Quality (AHRQ), the European Society of Cardiology (ESC)/Eurostat surveys, and Chinese national registries were used for trend triangulation and contextual background. Results From 1990 to 2021, the ASR and disease burden of RHD significantly decreased globally and in China (EAPC for DALYs in China: −4.8%, 95%UI: −5.0% to −4.6%). In contrast, the burden of NRVD and CAVD steadily increased in aging populations like those in China and the US, with a higher burden observed in older adults and males. In 2021, the incidence of NRVD and CAVD peaked in individuals aged ≥65 years, with rates being significantly higher in men than in women. RHD burden was concentrated in low socio-demographic index (SDI) regions, whereas NRVD/CAVD burden was strongly associated with high-SDI regions. Conclusion The global VHD epidemiological landscape is transitioning from an RHD-dominant to an NRVD/CAVD-dominant pattern. China faces a dual challenge of a residual RHD burden and a rapidly growing burden of degenerative valvular diseases. Developing tailored screening, prevention, and treatment strategies for different disease subtypes and populations is crucial.

Driven by policy initiatives promoting the integration of digital-intelligent technologies with primary healthcare and the digital transformation of traditional Chinese medicine (TCM), Smart TCM has emerged as a pivotal strategy for enhancing primary healthcare services for major chronic diseases. This paper reviews the current status, challenges, and feasible pathways of Smart TCM in community-level management of cardiovascular–cerebrovascular diseases and tumors, which represent major chronic disease burdens. Our findings indicate that Smart TCM demonstrates emerging potential in primary healthcare for chronic diseases across the entire continuum of “prevention-screening-diagnosis-treatment-management.” However, several significant challenges persist, including data silos and security vulnerabilities, limited applicability of existing models to real-world clinical needs, and insufficient digital literacy among primary healthcare physicians and elderly patients. To address these constraints, this paper proposes a multidimensional strategy encompassing the development of secure and interoperable regional data platforms, lightweight intelligent devices and support services aligned with primary care capacity, unified technical and data standards with corresponding quality control systems, adaptive and dynamically updated artificial intelligent models, interdisciplinary workforce training and patient education programs, and enhanced policy and health insurance support. Overall, Smart TCM shows great promise for improving the efficiency of primary healthcare delivery and establishing innovative TCM-based chronic disease management paradigms.

Ginsenoside Rg_2(GRg2) is a triterpenoid compound found in Panax notoginseng. This study explored its effects and mechanisms on diabetic retinopathy and angiogenesis. The study employed endothelial cell models induced by glucose or vascular endothelial growth factor(VEGF), the chorioallantoic membrane(CAM) model, the oxygen-induced retinopathy(OIR) mouse model, and the db/db mouse model to evaluate the therapeutic effects of GRg2 on diabetic retinopathy and angiogenesis. Transwell assays and endothelial tube formation experiments were conducted to assess cell migration and tube formation, while vascular area measurements were applied to detect angiogenesis. The impact of GRg2 on the retinal structure and function of db/db mice was evaluated through retinal thickness and electroretinogram(ERG) analyses. The study investigated the mechanisms of GRg2 by analyzing the activation of Yes-associated protein(YAP) and Toll-like receptors(TLRs) pathways. The results indicated that GRg2 significantly reduced cell migration numbers and tube formation lengths in vitro. In the CAM model, GRg2 exhibited a dose-dependent decrease in the vascular area ratio. In the OIR model, GRg2 notably decreased the avascular and neovascular areas, ameliorating retinal structural disarray. In the db/db mouse model, GRg2 increased the total retinal thickness and enhanced the amplitudes of the a-wave, b-wave, and oscillatory potentials(OPs) in the ERG, improving retinal structural disarray. Transcriptomic analysis revealed that the TLR signaling pathway was significantly down-regulated following YAP knockdown, with PCR results consistent with the transcriptome sequencing findings. Concurrently, GRg2 downregulated the expression of Toll-like receptor 4(TLR4), TNF receptor-associated factor 6(TRAF6), and nuclear factor-kappaB(NF-κB) proteins in high-glucose-induced endothelial cells. Collectively, GRg2 inhibits cell migration and tube formation and significantly reduces angiogenesis in CAM and OIR models, improving retinal structure and function in db/db mice, with its pharmacological mechanism likely involving the down-regulation of YAP expression.

Objective:To construct a perioperative pain nursing protocol for thoracoscopic surgery patients, providing a reference for clinical pain nursing practice.Methods:An evidence-based approach was used to search relevant guidelines and extract the best evidence. The initial draft was created through discussions among the research team, followed by two rounds of Delphi expert consultations. Based on the experts' suggestions, the protocol was revised and the best plan was finalized.Results:A total of 10 guidelines were included, and 22 experts participated in two rounds of consultations. The response rate for the consultation questionnaires was 100.00% (22/22) , with expert authority coefficients of 0.94 and 0.95 for the two rounds, respectively. The coefficient of variation for all indicators in the second round ranged from 0.04 to 0.24. The final pain nursing protocol included four primary indicators: personnel preparation, pain assessment, pain education, and pain intervention, with 10 secondary indicators and 27 tertiary indicators.Conclusions:The constructed perioperative pain nursing protocol for thoracoscopic surgery patients is significant, scientific, comprehensive, and targeted. It provides theoretical support and practical guidance for pain management, helping to reduce postoperative pain in patients.

Objective:To analyze the pathological features of recurrent cardiac myxoma to provide a reference basis for clinical treatment and postoperative follow-up.Methods:The pathological data of cardiac myxoma patients who underwent cardiac myxoma surgery in Beijing Anzhen Hospital, Beijing, China from 2002 to 2016 were retrospectively analyzed. According to the grouping criteria, the cases were divided into the recurrence group ( n=6) and control group ( n=73). Results:In the recurrence group, there were 3 females and 3 males with a median age of 47 years. In the control group, there were 49 females and 24 males, with a median age of 53 years. Cardiac myxoma usually occurred in the left atrium. In the recurrence group, 5 cases occurred in the left atrium and 1 case in the right atrium. In the control group, 68 cases occurred in the left atrium, 4 cases in the right atrium, and 1 case in bilateral atria. Among the 6 cases in the recurrence group, the recurrence time was 1-7 years, with average 4.8 years. In the univariate analysis of recurrent cardiac myxoma pathology, disruption of elastic fiber layer and tumor cells of the tumor stalk invading into the myocardium through the elastic fiber layer were statistically associated with recurrence of cardiac myxoma ( P<0.05). Logistic regression analyses showed that the invasion of tumor cells through the elastic fiber layer of the heart wall into the myocardium was an independent risk factor for recurrence ( Odds Ratio=0.999, P<0.05). Conclusion:During the pathologic diagnosis, assessing the relationship between tumor cells in the stalk of cardiac myxoma and elastic fiber layer can help estimate the recurrence risk of cardiac myxoma, and thus guide clinical treatment and postoperative follow-up.

Objective:To investigate the endocardial myocardial biopsy and ultrastructural features of heart failure patients with reduced ejection fraction, to determine their histopathologic phenotype, and to explore the diagnostic utility of endomyocardial biopsy in such patients.Methods:A total of 35 patients with heart failure with reduced ejection fraction diagnosed at Beijing Anzhen Hospital and underwent endomyocardial biopsy were collected between January 2022 and December 2023. The clinical features, histopathological, and ultrastructural characteristics were analyzed and compared with 11 patients with heart failure with preserved ejection fraction.Results:The age ranged from 35-58 years, with median age of 51 years; there were 26 males and 9 females. Myocardial fibrosis and myocardial fiber disorders were the most common histopathologic changes [97.1% (34/35) and 74.3% (26/35), respectively]. Myocardial fibrosis was not statistically different between the heart failure with reduced ejection fraction group and the heart failure with preserved ejection fraction group [13.3% (5.7%-21.4%) vs. 13.2% (9.3%-34.2%), P=0.279]. Significant ultrastructural changes were dense mitochondrial proliferation, vacuolar degeneration, and disorganized arrangement of myocardial fibers with localized lysis and fracture. After endomyocardial biopsy, the etiology was identified in 11 patients (31.4%,11/35), with a prevalence of cardiac amyloidosis of 17.1% (6/35). Conclusions:Endomyocardial biopsy is useful for early diagnosis and precise treatment in patients presenting with heart failure with reduced ejection fraction. Histopathological and ultrastructural analyses can uncover potential treatments, and predict and improve prognosis by providing relevant information for understanding the pathogenesis and clinical evolution.

Objective:To analyze the application effects and safety of continuous negative pressure drainage devices in postoperative drainage of congenital microtia reconstruction of auricle.Methods:A retrospective study was conducted, including 1 211 patients with congenital microtia treated at the Plastic Surgery Hospital of Chinese Academy of Medical Sciences and Peking Union Medical College from January 2018 to August 2021. All patients underwent auricular reconstruction surgery and were divided into two groups based on the type of negative pressure drainage device used. The study group consisted of 624 patients [315 males and 309 females, aged 6-24 (15.1±2.2) years], while the control group consisted of 587 patients [286 males and 301 females, aged 5-23 (14.7±2.3) years]. The study group used a novel negative pressure drainage ball, while the control group used a conventional negative pressure syringe for drainage. The preoperative and postoperative 1, 7 days scores of the modified Yale preoperative anxiety scale (mYPAS) and the quality of life scores postoperative 3 days (including functional activity, self-image, psychological health, satisfaction and pain) were compared between the two groups. All patients were followed up at 4, 8, 12, and 16 weeks postoperatively to compare the surgical scar area between the two groups. The incidence of adverse reactions within 12 weeks after surgery in two groups were recorded.Results:There was no significant difference in preoperative mYPAS scores between the two groups ( P=0.897). The mYPAS scores at 1 and 7 days after surgery were lower than the preoperative scores in both groups (all P<0.05), and the study group had significantly lower mYPAS scores at all time points than those of the control group (all P<0.001). The study group had higher scores in functional activity, self-image, psychological health, and satisfaction than those of the control group (all P<0.001), and a lower pain score than that of the control group ( P<0.001). Follow-up at 4, 8, 12, and 16 weeks showed that the surgical scar area was significantly smaller in the study group at all time points than in the control group (all P<0.001). The incidence of adverse reactions within 12 weeks after surgery was 9.0% (56/624) in the study group, which was lower than the 19.4% (114/587) in the control group ( P<0.001). Conclusion:The use of continuous negative pressure drainage devices in congenital microtia reconstruction of auricle is more effective and can reduce the incidence of postoperative adverse reactions.
