Objective To analyze the epidemiological characteristics and disease burden of liver cancer in Guangdong Province in 2020, and to provide a scientific foundation for the development of regionalized prevention and control strategies for liver cancer. Methods According to the cancer registry data of Guangdong Province, the incidence, mortality and age-standardized rate by Chinese standard population in 2020 were calculated to analyze the epidemiological characteristics of liver cancer. The disability adjusted life years (DALYs), year of life loss (YLL), year of lived with disability (YLD), and cause-eliminated life expectancy were used to assess the disease burden of liver cancer. Results In 2020, the crude incidence rate and the age-standardized incidence rate of liver cancer in Guangdong Province were 27.79/100 000 and 20.84/100 000，respectively, and the crude mortality rate and the age-standardized mortality rate of liver cancer were 25.49/100,000 and 17.64/100 000, respectively. The total DALY and DALY rate of liver cancer in Guangdong Province were 515 311 person-years and 513.83/100 000, respectively. After eliminating the causes of death from liver cancer, the life expectancy in Guangdong Province increased from 84.60 years to 84.99 years. All indicators consistently demonstrated that the burden of liver cancer was higher in males than that in females, and the burden of liver cancer was higher in rural areas than that in urban areas. Conclusion Liver cancer in Guangdong Province exhibits a high incidence, mortality and disease burden level in 2020. There are obvious differences of gender, age and region in cancer burden. It is necessary to strengthen liver cancer screening and diagnosis and treatment in men, the elderly and those in rural areas to reduce the burden of liver cancer gradually in Guangdong Province.

Narrative medicine focuses on empathy， relevance， and emotion， precisely aligning with the elements of “clown doctor” such as compassion， interaction， and pain relief. From the perspective of narrative medicine， the practice of “clown doctors” not only focuses on the emotional changes of patients but also enhances their sense of belonging by recreating their experiences. The key element for the success of “clown doctors” lies in establishing a multi-dimensional trust relationship among medical workers， patients， colleagues， and society， while ensuring their practice adheres to medical ethics norms. “Clown doctors” should concentrate on dimensions such as concept dissemination， clinical application， social recognition， and ethical practice of narrative medicine. They should also constantly optimize narrative techniques， deepen the understanding of patients’ stories， and intervene in the medical process in a more delicate and comprehensive way， thereby fostering in-depth communication and understanding between doctors and patients.

Intelligent prescription recommendation has become an important research direction in traditional Chinese medicine (TCM), offering new opportunities to support clinical decision-making and promote the modernization of TCM practice. With the rapid development of artificial intelligence (AI), a variety of computational approaches have been proposed to learn prescription patterns from clinical data and generate personalized treatment recommendations. However, despite increasing research activity, systematic and comprehensive reviews of AI-driven methods for TCM prescription recommendation remain limited. In this study, we present a comprehensive review of computational approaches for herbal prescription recommendation (HPR) in TCM. Existing methods are systematically categorized into several major paradigms, including traditional machine learning methods, topic model methods, sequential generative methods, deep learning and graph-based methods, and large language model–based frameworks. In addition to summarizing methodological developments, we also review commonly used public datasets and evaluation metrics in this field. Furthermore, representative models with publicly available implementations are experimentally evaluated on multiple benchmark datasets to provide a comparative analysis of their performance on the HPR task. Finally, we discuss the key challenges that hinder the practical deployment of intelligent prescription recommendation systems, including data heterogeneity, limited interpretability, and insufficient integration of TCM domain knowledge. Future research directions are outlined to facilitate the development of more reliable, interpretable, and clinically applicable AI-assisted HPR systems for TCM.

AIM: To investigate the association between dyslipidemia and macular hard exudates(HEs)in non-proliferative diabetic retinopathy(NPDR)secondary to type 2 diabetes mellitus(T2DM).METHODS: NPDR patients attending the outpatient ophthalmology clinic from January 2021 to December 2023 were selected and divided into three groups according to the severity of macular HEs. Group A: None or minimal HEs; Group B: Definite HEs; Group C: Prominent HEs. Total cholesterol(TC), triglycerides(TG), low-density lipoprotein cholesterol(LDL-C), high-density lipoprotein cholesterol(HDL-C), lipoprotein(a)[Lp(a)] levels and other lipid-related indicators were routinely measured. The correlation between these indicators and HEs was analyzed.RESULTS:Group A(24 eyes)consisted of 9 males and 15 females with the mean age of 54.71±6.15 y, group B(52 eyes)consisted of 20 males and 32 females with the mean age of 55.08±6.27 y, group C(14 eyes)consisted of 9 males and 5 females with the mean age of 53.93±6.08 y. The concentration of TC, TG, LDL-C and Lp(a)was highest in group C, followed by group B and lowest in group A with statistically significant differences(P<0.001). There were no statistically significant differences between the three groups for fasting plasma glucose(FPG), glycated hemoglobin A1c(HbA1c), creatinine(Cr), and HDL-C(P>0.05). The results of multivariate Logistic regression analysis showed that elevated levels of TC, TG, LDL-C, and Lp(a)were associated with the presence of macular HEs. Receiver operating characteristiccurve analysis showed that the area under the curve(AUC)for TC, TG, LDL-C, Lp(a), and their combination in predicting macular HEs in NPDR were 0.785, 0.718, 0.784, 0.742, and 0.911, respectively, with the combined model demonstrating the highest predictive performance.CONCLUSION: Dyslipidemia is closely associated with the development and progression of macular HEs in patients with NPDR and T2DM. The levels of TC, TG, LDL-C, and Lp(a)were correlated with the severity of macular HEs, suggesting that dyslipidemia may be involved in the pathological process of macular HEs formation.

Background Air pollution has widespread adverse health effects on human health, but research on its impact on reproductive health and related physiological mechanisms remains insufficient. Objective To investigate the associations between short-term exposure to particulate matter and nitrogen dioxide (NO₂) and serum levels of anti-Müllerian hormone (AMH) and testosterone in healthy adults. Methods A total of 152 healthy adults were recruited for a panel study, undergoing four follow-up visits from September 2019 to January 2020. Basic demographic information and serum samples were collected. Reproductive hormone levels were measured by enzyme-linked immunosorbent assay kits. Concurrently, environmental data in the study area were monitored, including fine particulate matter (PM_2.5), black carbon (BC), NO₂, particle number concentrations in the 5-560 nm size fraction (PNC_{5_560}), and meteorological variables. Linear mixed-effects models were constructed to estimate the effects of short-term exposure to these particulate matter on serum reproductive hormone levels. Results The participants had an average age of (23.9±2.4) years, with 102 women. For each interquartile range (IQR) increment in pollutant moving average concentrations, PM_2.5, PNC_{5_25}, PNC_{100_560}, BC, and NO₂ were associated with relative decreases in female serum AMH levels by 10.2%-16.9%, 46.2%-58.0%, 16.9%-21.2%, 14.8%-26.5%, and 11.3%-17.6%, respectively. These negative associations were stronger in females with waist-to-hip ratio > 0.76 and physical activity levels ≤ 1217 metabolic equivalents (MET) min per week. Similarly, in males, an IQR increase in the same pollutants was associated with relative decreases in serum free testosterone by 11.1%-17.2%, 35.2%, 10.5%-18.9%, 18.7%-24.2%, and 10.3%-26.0%, respectively. These effects were more pronounce in male with a waist-to-hip ratios > 0.81 and physical activity levels ≤ 1498 MET-min per week. Conclusion Short-term exposure to particulate matter and NO₂ may reduce serum levels of AMH and testosterone in healthy adults. Furthermore, these adverse effects appears to be stronger in adults with higher waist-to-hip ratios.

Cardiac aging is a key factor in the onset and progression of cardiovascular diseases. Investigating the traditional Chinese medicine （TCM） pathogenesis and therapeutic principles of cardiac aging is of great importance for curbing the common phenomenon of the heart aging faster than the body and implementing the national strategy in response to population aging. Essence （Jing）， Qi， and spirit （Shen） are the origin， driving force， and manifestation of life， respectively. The Essence-Qi-spirit theory within the Qi-collateral doctrine delineates the core pathogenesis and therapeutic principles of aging. This framework identifies kidney essence deficiency as the fundamental cause of aging， with primordial Qi depletion as a key factor and the consumption of body and spirit as its manifestations. Corresponding treatment principles involve tonifying the kidney to replenish essence， warming and supporting primordial Qi， and nourishing the body and spirit. During the process of tonifying the kidney， regulating Yin and Yang remains essential. Relevant studies indicate that this theoretical system provides significant guidance for anti-aging research in TCM. Guided by the Essence-Qi-spirit theory within the Qi-collateral doctrine， this paper posits that kidney essence constitutes the material foundation for cardiac development， and primordial Qi acts as the fundamental driver of cardiac function. Physical form and spirit together provide the structural carrier and functional manifestation of the heart. We further propose the core pathogenesis and therapeutic principles for cardiac aging. The fundamental pathogenesis lies in the deficiency and decline of kidney essence， leading to malnourishment of the heart. The key pathogenesis is the deficiency of primordial Qi， resulting in obstruction of the heart collateral. The manifestation involves the accumulation in the collateral and the dysfunction of the heart spirit. The corresponding treatment principles are tonifying the kidney and replenishing essence to nourish the heart， warming and reinforcing primordial Qi to unblock the heart collateral， and fortifying the physical form to invigorate the spirit mechanism. Existing studies demonstrate that Bazi Bushen Capsules， with the effects of tonifying the kidney， replenishing essence， warming primordial Qi， and fortifying the physical form and spirit， can delay cardiac aging. Guided by the Essence-Qi-spirit theory within the Qi-collateral doctrine， these findings support the development of effective herbal formulas to intervene in cardiac aging.

Through an in-depth exploration on dimensions of the value implications， inheritance challenges， and countermeasure paths of the red doctor culture， this paper systematically analyzed its historical origin and connotation， emphasizing its unique position in revolutionary history and significant value in the new era. Examining the challenges confronting the inheritance of the red doctor culture against the backdrop such as the rapid development of modern science and technology， changes in the social environment， weakened public cognition， and restricted dissemination channels， a three-dimensional countermeasure framework of “coordination， integration， and transformation” was proposed for the inheritance of the red doctor culture. This countermeasure included coordinating the layout to construct a systematic inheritance system， deepening integration to realize the innovation of educational inheritance， and transforming and empowering to embed and reconstruct the inheritance paradigm with modern thinking. The aim was to activate the vitality of the red doctor culture and promote its practical application and innovative development in contemporary medical and health undertakings.

Objective To investigate the efficacy and safety of EGFR-TKIs monotherapy and its combination therapy in the first-line treatment of advanced non-small cell lung cancer （NSCLC） patients with EGFR mutations. Methods Databases such as PubMed, Embase, Cochrane Library, and ClinicalTrials.gov were systematically searched to collect eligible phase Ⅱ/Ⅲ randomized controlled trials （RCTs）, with the time range from the establishment of the databases to June 2023. Two researchers independently screened the literature, extracted data, and assessed the risk of bias in the studies. Outcome data, including overall survival （OS）, progression-free survival （PFS）, objective response rate （ORR）, grade 3 or higher adverse events （≥3 AEs）, and serious adverse events （SAEs）, were collected. A network meta-analysis was performed using R software （version 4.2.1） under the Bayesian theoretical framework. Subgroup analyses of survival outcomes （OS, PFS） were conducted based on different clinical and pathophysiological characteristics of the patients. Results A total of twenty-eight phase Ⅱ/Ⅲ RCTs were included in the study, involving a total of 7 460 patients and 18 first-line treatment regimens. The results showed that in terms of efficacy, gefitinib + pemetrexed-containing chemotherapy performed best in OS and ORR, while osimertinib + bevacizumab performed best in PFS. In terms of safety, furmonertinib had the lowest incidence of ≥3 grade AEs, and osimertinib had the lowest incidence of SAEs. Subgroup analysis results indicated that the efficacy and safety of various treatment regimens differed among patients with different clinical and pathological characteristics. Conclusion Monotherapy with third-generation EGFR-TKIs, represented by osimertinib, serves as the preferred therapeutic option considering both efficacy and safety profiles. While some combination therapies could enhance survival benefits, need to be vigilant about increased toxicity. Clinical decision-making should be tailored based on patients’ mutation subtypes, comorbidities, and tolerance.

Immunoglobulin A nephropathy （IgAN） is the primary glomerulonephritis with the highest incidence rate in the world. It is also the main cause of end-stage renal disease （ESRD） in China， which has brought heavy economic burden to the society and patient families. Traditional Chinese medicine （TCM） has certain advantages in treating IgAN. In TCM， IgAN is classified into consumptive disease， hematuria， and edema categories， with the location in the kidney and involving the lung， liver， and spleen. Professor Ren Jixue， a master of TCM， believes that kidney deficiency and spleen deficiency are the root causes of IgAN， and the throat is the source of the disease. He proposed the theory of throat-kidney correlation and used the method of tonifying kidney and invigorating spleen as well as detoxifying and relieving sore-throat to treat IgAN， achieving significant therapeutic effects. Studies have shown that IgAN is closely related to mucosal immune defense. IgAN patients often experience recurrent and gradually worsening symptoms due to mucosal infections， and polymeric Ig receptor （PIgR） is an important component of mucosal defense function. The lack of PIgR leads to the accumulation of IgA molecules in the mucosal lamina propria， and the molecules enter the bloodstream in large quantities and ultimately deposit in the kidneys， causing kidney damage. Complement regulatory protein complement receptor type 1 （CR1） exists on red blood cells and glomeruli and has the function of inhibiting the activation and differentiation of B cells， clearing immune complexes， and inhibiting excessive activation of the complement system. Therefore， regulating the immune defense function through the mucosal-renal axis mediated by PIgR-CR1 will be an important target for preventing and treating IgAN. Based on the theory of throat-kidney correlation， this article explores the effects and molecular mechanisms of tonifying kidney and invigorating spleen as well as detoxifying and relieving sore-throat in preventing and treating IgAN by regulating the mucosal-kidney axis mediated by PIgR-CR1. It provides effective theoretical support and a scientific basis for TCM prevention and treatment of IgAN based on the theory of throat-kidney correlation.
