In modern society, the comorbidity of insomnia with amnesia has shown a significantly increasing incidence and become increasingly severe, emerging as a public health issue that endangers people's physical and mental health and quality of life. Anmei Dan (AMD), originally recorded in the Shishi Milu by CHEN Shiduo in the Qing Dynasty, possesses profound theoretical foundations and distinct clinical advantages in ameliorating insomnia with amnesia. Basic research has unequivocally confirmed its definite therapeutic effects on insomnia with amnesia and revealed partial mechanisms. AMD is therefore a veritable classic prescription embodying the principle of treating different diseases with the same method for insomnia and amnesia. However, few researchers have reviewed the related research progress. This article systematically summarized the theoretical connotations of traditional Chinese medicine in treating insomnia with amnesia, delineated the multi-component material basis of AMD in ameliorating insomnia with amnesia (including various chemical components such as ginsenosides, jujubosides, and salvianolic acids), and evaluate its multi-dimensional clinical efficacy (e.g., prolonging total sleep time, improving sleep efficiency, and enhancing memory). Moreover, it systematically summarizes the multi-pathway mechanisms of action. The results indicate that AMD has a clear material basis, definite clinical efficacy, and a favorable safety profile in ameliorating insomnia and amnesia. AMD may exert the therapeutic effect by regulating sleep-wake rhythms, enhancing synaptic plasticity, inhibiting neuroimmune inflammation, and modulating autophagy, oxidative stress, and energy metabolism. In conclusion, AMD exerts synergistic effects through multi-component, multi-dimensional, and multi-pathway approaches, serving as an important prescription for enriching and developing the theory of treating different diseases with the same method for insomnia with amnesia.

Diabetic tendinopathy is a common and disabling musculoskeletal complication of diabetes, clinically characterized by tendon thickening, pain, impaired healing capacity and compromised biomechanical performance, collectively undermining joint function and quality of life. Its pathogenesis is multifactorial. On the one hand, chronic hyperglycaemia promotes the abnormal accumulation of advanced glycation end products (AGEs) within tendon collagen, leading to non-enzymatic crosslinking and engagement of the receptor for AGEs (RAGE), which in turn triggers inflammasome activation and sustains inflammatory responses. On the other hand, the diabetic milieu disrupts collagen metabolic homeostasis, impairs microvascular function and induces peripheral neuropathy; together, these alterations drive extracellular matrix degeneration and weaken the mechanical properties of tendon. Exercise, as a non-pharmacological intervention, can ameliorate these pathological changes through multiple integrated mechanisms. First, exercise attenuates tendon inflammation and restores microenvironmental homeostasis. Regular physical activity reduces AGE-RAGE signalling, thereby suppressing downstream expression of tumour necrosis factor (TNF) and interleukin-1β (IL-1β), while upregulating the anti-inflammatory cytokine interleukin-10 (IL-10). This shift from a pro-inflammatory to a pro-resolving milieu not only restrains chronic inflammation but may also limit excessive inflammasome activation in tenocytes and tissue-resident immune cells. Second, exercise enhances local expression of insulin-like growth factor 1 (IGF-1), thereby activating the phosphoinositide 3-kinase (PI3K)-protein kinase B (Akt) signalling pathway. This axis stimulates tenocyte proliferation, augments synthesis of type I collagen —— the principal load-bearing component of tendon —— and thereby promotes tissue repair, preserves tensile strength and supports matrix synthesis and structural integrity. In addition, exercise improves blood supply and nutrient delivery to tendon by increasing the expression of vascular endothelial growth factor (VEGF), connective tissue growth factor (CTGF) and the small leucine-rich proteoglycan decorin (DCN), thereby enhancing capillary growth, coordinating collagen fibrillogenesis and actively suppressing pathological vascular calcification. Exercise also increases the expression of angiopoietin-like 4 (ANGPTL4), fibroblast growth factor 2 (FGF-2) and CD34. Through the concerted actions of these factors, exercise promotes angiogenesis, restores the microvascular network and ensures adequate oxygen and nutrient supply to relatively ischaemic tendon tissue. Finally, exercise elevates levels of brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF), supporting neuronal survival, axonal growth and the function of sensory and sympathetic nerve endings within tendon, thereby exerting neurotrophic and neuromodulatory effects and improving tendon innervation and neuromuscular control. Moreover, exercise upregulates collapsin response mediator protein 2 (CRMP-2), a molecule involved in axonal guidance and regeneration, and moderately increases the activity of substance P (SP), thereby helping to regulate neurogenic inflammation, pain perception and trophic support for tenocytes. Drawing together current evidence, this review systematically summarizes the mechanisms underlying diabetic tendinopathy and examines the mechanistic basis of exercise intervention, with the aim of providing a theoretical framework for the development of precise exercise strategies for affected individuals. However, several key issues remain unresolved: the therapeutic efficacy and mechanistic specificity of different exercise modalities in diabetic tendinopathy have yet to be defined, and early diagnostic biomarkers remain insufficiently characterized. Future studies should apply multi-omics approaches to profile AGE subtypes, miRNA signatures and collagen metabolic products, and should also clarify the adverse effects and underlying mechanisms of excessive exercise or mechanical overloading in diabetic tendinopathy. Such efforts will further elucidate the therapeutic effects and mechanisms of exercise in diabetic tendinopathy and provide a stronger basis for precision exercise prescription and fitness guidance in patients with diabetes.

Cancer-related anorexia (CRA) is a common and severe complication of malignant tumors. It is characterized by persistent appetite loss, early satiety, and reduced food intake. It directly leads to malnutrition, decreased treatment tolerance, reduced quality of life, and worsened prognosis. Its pathogenesis is complex, involving a multilayered network of interactions, including the dysregulation of the hypothalamic feeding center, imbalance of peripheral appetite hormones and systemic inflammatory mediators, and actions of tumor-derived factors. It is also highly influenced by anticancer treatments, such as chemotherapy, radiotherapy, and surgery. Current clinical management is dominated by multimodal comprehensive therapy based on progestogens, glucocorticoids and prokinetic agents, combined with nutritional support, rehabilitation exercise, psychological intervention and traditional Chinese medicine. However, highly effective approaches capable of fundamentally reversing the disease course of CRA are still lacking. This article provides a systematic review of the pathophysiological mechanisms, clinical assessment tools, and comprehensive treatment strategies for CRA. It also presents a discussion on future research directions based on the latest advances to provide a theoretical basis and reference for optimizing clinical practice and developing novel intervention strategies.

As an exclusive Miao medicine of Honwing Pharma (Guizhou) Co. Ltd., Yifei Zhike capsules are both a prescription drug and an over-the-counter (OTC) drug. Its main ingredients include Ranunculus ternatus and Panax notoginseng. With the effects of nourishing Yin and moistening the lungs, as well as relieving cough and reducing phlegm, Yifei Zhike capsules are often used in the treatment of acute and chronic bronchitis, pulmonary tuberculosis, and other diseases. However, there is insufficient understanding of their efficacy, suitable syndromes, and safety in clinical practice, with a lack of relevant expert consensus on clinical application. To standardize their clinical application, 30 experts from the fields of respiratory medicine, pharmacy, and evidence-based medicine were invited to develop an Expert Consensus on the Clinical Application of Yifei Zhike Capsules (Consensus for short) through evidence-based medicine methods. The Consensus clarified the syndrome characteristics, disease stages, dosages, treatment courses, combined medication, and other norms in the treatment of acute/chronic bronchitis and pulmonary tuberculosis and could be applicable to clinical physicians and pharmacists in medical and health institutions at all levels. In disease diagnosis, it provided diagnostic criteria for traditional Chinese medicine and Western medicine and clarified that the suitable traditional Chinese medicine syndrome was the syndrome of Qi-Yin deficiency with intermingled phlegm-blood stasis. Clinical studies have confirmed that Yifei Zhike capsules combined with standard anti-tuberculosis therapy can effectively improve the symptoms of pulmonary tuberculosis patients, increase the sputum smear conversion rate, and promote the absorption of lesions. When treating acute cough caused by respiratory tract infections, Yifei Zhike capsules can increase the markedly effective rate and the seven-day disappearance rate of cough symptoms. Meanwhile, recommendations for specific usage, dosages, and treatment courses were given for different diseases, and it was pointed out that long-term medication required key monitoring of adverse reactions. In safety, the adverse reactions of Yifei Zhike capsules involved multiple aspects such as the digestive system and allergic reactions, and pregnant women and women during menstruation were prohibited from using it. In addition, modern research has shown that Yifei Zhike capsules have an adjuvant therapeutic effect on tuberculous pleurisy and may be effective for inflammatory and benign pulmonary nodules. However, further research should be conducted on the toxicological safety of long-term medication. The formulation of the Consensus provides a scientific basis for the rational clinical application of Yifei Zhike capsules, which helps to improve clinical efficacy and reduce medication risks.

The compilation instructions for the Expert Consensus on Clinical Application of Yifei Zhike Capsules systematically expound the development background, methodological framework, and core achievements of this consensus. In view of the problems existing in the clinical application of Yifei Zhike Capsules, such as insufficient efficacy evidence and lack of standardized syndrome differentiation, the Institute of Basic Research in Clinical Medicine, China Academy of Chinese Medical Sciences took the lead and collaborated with 21 tertiary grade-A hospitals and research institutions across China to form a multidisciplinary expert group (comprising 30 experts in clinical medicine, pharmacy, and methodology). The compilation work was carried out in strict accordance with the World Health Organization (WHO) guidelines, the GB/T 1.1-2020 standard, and the writing specifications for the explanatory notes of expert consensus on clinical application of Chinese patent medicines. Through systematic literature retrieval (including 32 studies, with 24 clinical studies), Grading of Recommendations Assessment, Development and Evaluations (GRADE)-based evidence grading, and multiple rounds of discussions using the nominal group method (25 experts voted to determine 17 clinical questions), 5 evidence-based recommendations and 11 expert consensus suggestions were formed. It is clarified that this medicine (Yifei Zhike Capsules) is applicable to the treatment of expectoration/hemoptysis in acute and chronic bronchitis and the adjuvant treatment of pulmonary tuberculosis. It is recommended that it can be used alone or in combination with anti-tuberculosis drugs. The safety evaluation shows that this medicine mainly induces the following adverse reactions: mild gastrointestinal reactions (such as nausea and abdominal pain) and rashes. The contraindicated populations include pregnant women and women during menstruation. The compilation process of the consensus underwent three rounds of expert letter reviews, two rounds of peer reviews, and quality control assessments to ensure methodological rigor and clinical applicability. In addition, through policy alignment, academic promotion, and a dynamic revision mechanism, the standardization of clinical application was promoted, providing a demonstration for the evidence-based transformation of characteristic therapies of Miao medicine.

Objective To introduce a modified technique of right ventricular outflow tract (RVOT) reconstruction using a handmade bicuspid pulmonary valve crafted from expanded polytetrafluoroethylene (ePTFE) and to summarize the early single-center experience. Methods Patients with complex congenital heart diseases (CHD) who underwent RVOT reconstruction with a handmade ePTFE bicuspid pulmonary valve due to pulmonary regurgitation at Guangdong Provincial People’s Hospital from April 2021 to February 2022 were selected. Postoperative artificial valve function and right heart function indicators were evaluated. Results A total of 17 patients were included, comprising 10 males and 7 females, with a mean age of (18.18±12.14) years and a mean body weight of (40.94±19.45) kg. Sixteen patients underwent reconstruction with a handmade valved conduit, with conduit sizes ranging from 18 to 24 mm. No patients required mechanical circulatory support, and no in-hospital deaths occurred. During a mean follow-up period of 12.89 months, only one patient developed valve dysfunction, and no related complications or adverse events were observed. The degree of pulmonary regurgitation was significantly improved post-RVOT reconstruction and during follow-up compared to preoperative levels (P<0.001). Postoperative right atrial diameter, right ventricular diameter, and tricuspid regurgitation area were all significantly reduced compared to preoperative values (P<0.05). Conclusion The use of a 0.1 mm ePTFE handmade bicuspid pulmonary valve for RVOT reconstruction in complex CHD is a feasible, effective, and safe technique.
