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.

Andrological diseases have become an important public health problem threatening men's health worldwide， which significantly affects the quality of life of patients and brings a heavy disease burden. Western medicine often faces the dilemma of obvious side effects and limited efficacy. Traditional Chinese medicine has unique advantages in the prevention and treatment of andrological diseases and has accumulated rich clinical experience. Epimedii Folium， as a traditional Chinese medicine for strengthening kidney and Yang， exerts a key therapeutic effect on andrology diseases through multi-component synergy， multi-target regulation， and multi-pathway intervention. Recent studies have found that the main active components of Epimedii Folium， such as icariin， icariside， and icaritin， are the key material basis for the treatment of andrological diseases. The active components of Epimedii Folium can play a role in common andrological diseases such as erectile dysfunction， male infertility， and prostate cancer by regulating the activity of the nitric oxide/cyclic guanosine monophosphate （NO/cGMP） pathway， participating in oxidative stress response， regulating the secretion of hypothalamic-pituitary-gonadal axis hormones， improving spermatogenic dysfunction， and inhibiting the proliferation of cancer cells. However， the systematic action network and molecular mechanisms of the active components of Epimedii Folium have not been fully elucidated， thereby limiting its potential for clinical translation and application. In the future， it is necessary to combine cutting-edge technologies such as metabolomics， single-cell sequencing， and targeted nanoscale drug delivery systems， strengthening the research on the compatibility rules of active components and organ-specific delivery， providing a scientific basis for the development of innovative andrology traditional Chinese medicine formulas with international competitiveness， and promoting the innovation and breakthrough of andrology disease treatment modes.

Amoenucles A-F (1-6), six previously undescribed nucleoside derivatives, and two known analogs (7 and 8) were isolated from the culture of Aspergillus amoenus TJ507. Their structures were elucidated through spectroscopic analysis, single-crystal X-ray crystallography, and chemical reactions. Notably, 3 and 4 represent the first reported instances of nucleosides with an attached pyrrole moiety. Of particular significance, the absolute configuration of the sugar moiety of 1-4 was determined using nuclear magnetic resonance (NMR), electric circular dichroism (ECD) calculations, and a hydrolysis reaction, presenting a potentially valuable method for confirming nucleoside structures. Furthermore, 1, 2, and 5-8 exhibited potential tumor necrosis factor α (TNF-α) inhibitory activities, which may provide a novel chemical template for the development of agents targeting autoimmune and inflammatory diseases.

Hepatic ischemia/reperfusion injury (IRI) remains a critical complication contributing to graft dysfunction following liver surgery. As part of an ongoing search for hepatoprotective natural products, five previously unreported homoadamantane-type polycyclic polyprenylated acylphloroglucinols (PPAPs), named hyperhomanoons A-E (1-5), and one known analog, hypersampsone O (6), were isolated from Hypericum patulum. Among these, compound 6 demonstrated potent protective effects against CoCl₂-induced hypoxic injury in hepatocytes. Furthermore, in a murine model of hepatic IRI induced by vascular occlusion, pretreatment with 6 markedly alleviated liver damage and reduced hepatocyte apoptosis. This study is the first to identify PPAPs as promising scaffolds for the development of therapeutic agents targeting hepatic IRI, underscoring their potential as lead compounds in drug discovery efforts for ischemic liver diseases.

OBJECTIVE: This study aimed to explore the association between body mass index (BMI) and mortality based on the 10-year population-based multicenter prospective study. METHODS: A general population-based multicenter prospective study was conducted at four sites in rural China between 2013 and 2023. Multivariate Cox proportional hazards models and restricted cubic spline analyses were used to assess the association between BMI and mortality. Stratified analyses were performed based on the individual characteristics of the participants. RESULTS: Overall, 19,107 participants with a sum of 163,095 person-years were included and 1,910 participants died. The underweight (< 18.5 kg/m ²) presented an increase in all-cause mortality (adjusted hazards ratio [ aHR] = 2.00, 95% confidence interval [ CI]: 1.66-2.41), while overweight (≥ 24.0 to < 28.0 kg/m ²) and obesity (≥ 28.0 kg/m ²) presented a decrease with an aHR of 0.61 (95% CI: 0.52-0.73) and 0.51 (95% CI: 0.37-0.70), respectively. Overweight ( aHR = 0.76, 95% CI: 0.67-0.86) and mild obesity ( aHR = 0.72, 95% CI: 0.59-0.87) had a positive impact on mortality in people older than 60 years. All-cause mortality decreased rapidly until reaching a BMI of 25.7 kg/m ² ( aHR = 0.95, 95% CI: 0.92-0.98) and increased slightly above that value, indicating a U-shaped association. The beneficial impact of being overweight on mortality was robust in most subgroups and sensitivity analyses. CONCLUSION This study provides additional evidence that overweight and mild obesity may be inversely related to the risk of death in individuals older than 60 years. Therefore, it is essential to consider age differences when formulating health and weight management strategies.

ObjectiveTo analyze the incidence and influencing factors of postherpetic neuralgia (PHN) among herpes zoster (HZ) patients aged 50 years and above in the community-based population of Shanghai who had not received the recombinant zoster vaccine (RZV), so as to provide data support for formulating PHN prevention strategies. MethodsBased on baseline survey data, physical examinations, biochemical indicator tests, annual clinical diagnosis and treatment data from the Shanghai Suburban Adult Cohort, as well as the RZV vaccination data from the vaccination information platform of the Center for Disease Control and Prevention, the cumulative incidence rate of PHN was calculated. Logistic regression analyses were used to analyze the influencing factors of PHN. ResultsA total of 48 261 participants were included in this study, with 2 406 newly diagnosed HZ cases, among whom 11 had received at least one dose of RZV. Among 2 395 unvaccinated HZ patients, 262 new PHN cases were identified, with a cumulative incidence rate of 10.94% (95%CI: 9.72%‒12.26%). Factors influencing PHN incidence included age 70‒79 years (OR=2.069, 95%CI: 1.427‒3.028), history of immunosuppresant utilization (OR=1.592, 95%CI: 1.227‒2.072), and history of stroke (OR=1.657, 95%CI: 1.015‒2.605). For male patients, the influencing factors for PHN were age 70‒79 years (OR=2.319, 95%CI: 1.195‒4.802) and history of chronic bronchitis (OR=1.935, 95%CI: 1.010‒3.517), whereas, for female patients, age 70‒79 years (OR=1.767, 95%CI: 1.107‒2.831), history of immunosuppresant use (OR=1.603, 95%CI: 1.151‒2.245), history of stroke (OR=1.906, 95%CI: 1.059‒3.277), and alcohol consumption (OR=3.698, 95%CI: 1.093‒12.517) were influencing factors for PHN. ConclusionIndividuals with advanced age, history of immunosuppresant utilization, stroke, chronic bronchitis, and alcohol consumption are at high risk for PHN. These individuals should be prioritized for RZV vaccination to reduce the occurrence of PHN and improve their quality of life.

Objective: To summarize the treatment methods and efficacy of a patient with pure red cell aplasia (PRCA) after allogeneic hematopoietic stem cell transplantation (allo-HSCT), and to accumulate relevant case data. Methods: The clinical treatment and laboratory test data of a patient with PRCA after allo-HSCT in our hospital were retrospectively collected. The therapeutic strategy, monitoring parameters, and treatment outcomes were summarized. Results: Upon suspicion of post-transplant PRCA, the patient was promptly treated with intravenous injection of human immunoglobulin and three sessions of plasma exchange. The titer of blood group antibodies in the patient decreased, and the hemolytic symptoms were relieved. Over one year post-transplantation, the patient exhibited a sustained impairment of erythropoiesis, necessitating continued red blood cell transfusions. After treatment with intravenous daratumumab (400 mg twice weekly for 4 weeks), the pateint's hemoglobin (Hb) and reticulocyte (Ret) levels normalized rapidly, the ABO blood type converted from the recipient to the donor type, and the titer of IgM blood group antibodies returned to normal. The patient was successfully weaned off red blood cell transfusions, indicating the clinical efficacy of the treatment. Conclusion: Daratumumab shows effectiveness in the treatment of refractory PRCA after allo-HSCT in the case. It is essential to monitor Hb, Ret and the titer of blood group antibodies during treatment. Nevertheless, the interference of daratumumab with the titer of blood group antibodies should be considered.

Transmission X-ray tubes are relatively new devices characterized by portability,suitability for miniaturization,and low requirements for shielding,making them ideal radiation sources for kilovoltage X-ray therapy.However,their application in radiotherapy remains underexplored.An electron target model of a transmission X-ray tube is developed using the Monte Carlo toolkit TOPAS 3.8.1.The study investigates the effect of tungsten target thickness on X-ray output efficiency,finding that a tube voltage of 50 kV and a tungsten thickness of 1.4 μm yields the highest emission efficiency.Based on the energy spectrum at this optimal efficiency,polynomial fitting approach is applied to determine the corresponding aluminum filter thickness for mean energies ranging from 20 keV to 35 keV,achieving a mean fitting error of 0.91%.Next,the study simulates dose deposition in a water phantom for spectra with different mean energies and various source-to-surface distances,and plots percent-depth-dose curves,relative normalized dose-depth curves,and relative normalized dose histograms under each treatment condition.Finally,the simulated results are compared with experimental data from the intraoperative radiotherapy system Intrabeam and the superficial X-ray therapy unit SRT-100,obtaining average relative errors of 3.71%and 4.38%,respectively.These findings provide a theoretical foundation for further optimization of transmission X-ray tubes in kilovoltage radiotherapy.

Objective To explore the clinical application effects of artificial dermis in the repair of traumatic finger skin defects with bone exposure.Methods From January 2022 to January 2024,10 patients with fingertip skin defects and bone exposure,totaling 10 fingers,were treated.The defect areas ranged from 0.5 cm × 1.0 cm to 1.0 cm × 1.5 cm.After debridement,the wounds were covered with artificial dermis,and regular dressing changes were performed postoperatively.The artificial dermis was removed 3-4 weeks post-surgery.The wound healing,skin appearance,and sensory recovery of the fingertip were evaluated.Results All 10 fingertip wounds healed successfully,with a healing time of 3 to 4 weeks.Patients were followed up for more than 3 months,and the wound healing was satisfactory.The finger pads appeared full,the skin was smooth and flat with no obvious scarring,and the texture was soft.Skin sensory ability recovered well,with no pain or hypersensitivity,and the two-point discrimination ability reached 3 to 8 mum.According to the upper limb function evaluation standards set by the Hand Surgery Society of the Chinese Medical Association,the sensory recovery of all 10 fingertips achieved an S3+level,with a good to excellent rate of 100％.Conclusion The primary repair of fingertip skin defects with bone exposure using artificial dermis resulted in no donor site damage.The surgical procedure is safe and simple,and the appearance and sensory function of the fingers have recovered well,demonstrating reliable efficacy.
