ObjectiveTo construct a multifunctional liposomal delivery system by replacing cholesterol(Chol) in conventional liposomes with saikosaponin D(SSD) and modifying with poloxamer 407(P407) for co-delivery of curcumin(Cur). The system was evaluated for in vivo tumor targeting and inhibitory effects on mouse subcutaneous solid tumors. MethodsSingle-factor and orthogonal tests combined with information entropy weighting were used to optimize the formulation process of the liposome with encapsulation efficiency and absolute Zeta potential as indexes, and validation studies and liposomal characterization were performed. A subcutaneous solid tumor model was established by injecting H22 hepatocellular carcinoma cells subcutaneously into the dorsal surface of the right forelimb of mice. DiR-loaded traditional Chol liposomes(P407-DiR-Chol-LPs, PDCL) and novel SSD-based liposomes(P407-DiR-SSD-LPs, PDSL) were prepared by the optimized formulation process, and tail vein injection was performed to investigate the impact of SSD on liposome tumor targeting with small animal in vivo imaging. Mice were randomly divided into eight groups, including blank group, model group, free doxorubicin(DOX) group(2 mg·kg-1), free Cur group(8 mg·kg-1), free SSD group(10 mg·kg-1), P407-Cur-Chol-LPs(PCCL) group, P407-SSD-LPs(PSL) group, and P407-Cur-SSD-Lps(PCSL) group. Treatments were administered intraperitoneally every other day for seven doses. Antitumor efficacy and biocompatibility were evaluated by monitoring body weight change, organ indices, tumor volume and mass, relative tumor proliferation rate(T/C), and tumor growth inhibition rate(TGI). Histopathological analysis of liver, kidney, and tumor tissues was performed using hematoxylin-eosin(HE) staining. Serum levels of aspartate aminotransferase(AST), alanine aminotransferase (ALT), blood urea nitrogen(BUN), and creatinine(Crea)in mice were quantified by fully automated biochemical analyzer. ResultsOrthogonal test yielded optimal ratios of Cur, SSD, and P407 to soybean phosphatidylcholine(SPC) as 1∶25, 1∶20, and 1∶4. The optimized PCSL exhibited spherical morphology with a particle size of 179.15 nm, a Zeta potential of -47.25 mV, and an encapsulation efficiency of 96.40%. Its in vitro release profile conformed to first-order kinetics, demonstrating excellent storage stability and hemocompatibility. In vivo imaging revealed that the fluorescence signal in tumor tissues and the fluorescence intensity ratio between tumors and organs were significantly higher in the PDSL group than in the PDCL group(P<0.05, P<0.01). Among the treatment groups, PCSL group showed superior efficacy over free Cur group, free SSD group, PCCL group, and PSL group, with TGI>40% and T/C<60%, indicating pronounced anti-hepatocellular carcinoma effects(P<0.05, P<0.01). Histopathology and serum biochemistry indicated minimal hepatorenal toxicity and improved hepatic and renal function in PCSL-treated mice. ConclusionReplacing Chol with SSD in preparing multifunctional drug delivery systems not only stabilizes liposomes but also yields superior anti-hepatocellular carcinoma efficacy, achieving the effect of drug-excipient integration. Co-delivery of Cur via this system can be used for treating subcutaneous solid tumors in hepatocellular carcinoma, providing new insights and technical approaches for anti-hepatocellular carcinoma research and the meridian-guiding and messenger-directing theory in traditional Chinese medicine.

Chinese Medical Ethics 2026;39(2):256-262
The red doctor spirit is a unique spiritual form and value pursuit nurtured. It was nurtured and formed during the medical practice of the Communist Party of China leading the vast medical workers to integrate the basic principles of Marxism with the concrete realities of the Chinese revolution and with the excellent traditional Chinese medical ethics culture. It constitutes not only an important component of the spiritual spectrum of the Chinese Communists but also a significant source of the health and wellness culture of socialism with Chinese characteristics. Employing the analytical framework of the “two integrations,” this paper conducted an in-depth analysis of the generative logic of the red doctor spirit. It revealed that this spirit was not only the creative transformation and concrete manifestation of Marxist core concepts such as human emancipation and the people-centered stance in the medical and health practices of the Chinese revolution, but also an integration and elevation of traditional medical ethics like “the caring heart of a physician” and “a master physician must have superb skill and sincerity” in the excellent traditional Chinese culture with the red revolutionary culture at the practical level. This paper argued that the generation of the red doctor spirit was the product of a dialectical unity regarding theoretical guidance, cultural nourishment, and practical exploration under specific historical conditions. Situated in the new era, the red doctor spirit continues to exhibit strong vitality and irreplaceable contemporary value in aspects such as adhering to the people-first principle, advancing the healthy China initiative, strengthening medical ethics and professional conduct, carrying forward the red gene, and cultivating new generations for the era.

Chronic obstructive pulmonary disease(COPD), characterized primarily by persistent airflow limitation and chronic airway inflammation, is a major chronic respiratory disease with persistently high morbidity and mortality. In recent years, macrophage pyroptosis, as an inflammatory form of programmed cell death, has been recognized as playing a key role in amplifying inflammatory responses and promoting tissue damage. According to traditional Chinese medicine(TCM) theory, spleen failing to disperse essence constitutes an important pathological basis for various chronic diseases, clinically manifesting as impaired transportation and transformation, internal generation of phlegm-dampness, and accumulation of turbid toxins. Based on a review of classical TCM pathogenesis and modern molecular biological research, this study proposes that there may be a correlation between spleen failing to disperse essence and macrophage pyroptosis in the pathogenesis of COPD. Specifically, metabolic and immune disturbances such as glucotoxicity, lipotoxicity, and enterotoxicity may trigger macrophage pyroptosis through the advanced glycation end products(AGEs)/AGEs receptor(RAGE)/reactive oxygen species(ROS), fatty acids/Toll-like receptor 4(TLR4), and lipopolysaccharide(LPS)/nuclear transcription factor-κB(NF-κB)/NOD-like receptor protein 3(NLRP3) signaling pathways. Excessive pyroptosis, in turn, exacerbates metabolic dysregulation and inflammatory responses, forming a vicious cycle. Furthermore, TCM interventions such as strengthening the spleen and tonifying Qi, as well as resolving dampness and detoxifying, have demonstrated potential in modulating pyroptosis-related signaling pathways, including NF-κB, the NLRP3 inflammasome, and autophagy. In summary, this article explores the role of spleen failing to disperse essence-macrophage pyroptosis mechanism in COPD and highlights possible therapeutic strategies of TCM, providing new insights for integrated Chinese and western medical research and clinical practice.

Olfactory receptors (ORs) form the largest superfamily of G protein-coupled receptors (GPCRs). Traditionally recognized for their role in the nasal olfactory epithelium, where they mediate the sense of smell, accumulating evidence has firmly established their ectopic expression in non-olfactory tissues, including the intestine, lungs, and kidneys. The intestine, as the primary site for nutrient digestion and absorption, harbors a highly complex chemical environment. To adapt to this environment, the gut employs a sophisticated network of “chemosensors” to monitor luminal contents and maintain homeostasis. Among these sensors, intestinal ORs have emerged as crucial functional components, serving as a molecular bridge that connects environmental chemical signals—such as food-derived odorants—to specific physiological responses. This discovery has significantly deepened our understanding of how dietary flavors and compounds influence intestinal physiology at the molecular level. This review systematically summarizes the expression profiles, ligand classification, and biological functions of ORs within the gastrointestinal tract. Studies indicate that intestinal ORs exhibit distinct spatial distribution patterns across different gut segments and display cell-type specificity, particularly within enterocytes and enteroendocrine cells. These receptors function as versatile sensors capable of recognizing a wide variety of ligands, including exogenous dietary components, gut microbiota metabolites such as short-chain fatty acids, and endogenous small molecules like azelaic acid. Upon activation by specific ligands, intestinal ORs trigger intracellular signaling cascades, primarily involving the AC-cAMP-PKA pathway or calcium influx channels. A major focus of this review is to elucidate the molecular mechanisms by which these receptors regulate the secretion of gut hormones. Activation of specific ORs in enteroendocrine cells has been shown to stimulate the release of hormones such as glucagon-like peptide-1 (GLP-1), peptide YY (PYY), and serotonin (5-HT), thereby modulating systemic energy metabolism, glucose homeostasis, and gastrointestinal motility. Furthermore, the review addresses the critical roles of ORs in immune regulation and pathology. Evidence suggests that specific ORs contribute to the maintenance of intestinal immune homeostasis and may offer protection against inflammation. Beyond their involvement in inflammatory responses, ORs such as Olfr78 have been shown to regulate the differentiation and function of intestinal endocrine cells. Similarly, Olfr544 has been demonstrated to alleviate intestinal inflammation by remodeling the gut microbiome and metabolome. These findings collectively suggest that specific ORs hold promise as therapeutic targets for mitigating intestinal inflammation and maintaining gut homeostasis. Additionally, the review explores the emerging role of ORs in cancer. Although OR expression is often downregulated in tumor tissues compared to normal mucosa, activation of specific ORs by certain ligands can inhibit tumor cell proliferation and migration and induce apoptosis via pathways such as MEK/ERK and p38 MAPK. Conversely, other receptors, such as OR7C1, may serve as biomarkers for cancer-initiating cells. In conclusion, intestinal ORs represent a vital component of the gut’s sensory network. The review also discusses the translational potential of these findings. By elucidating the precise pairing relationships between dietary components and specific ORs, novel therapeutic strategies could be developed. Intestinal ORs may thus emerge as promising targets for nutritional and pharmacological interventions in metabolic diseases, inflammatory bowel diseases, and malignancies.

Background: Chinese herbal pieces are an essential component of traditional Chinese medicine. Accurate identification and classification of these materials are crucial in clinical practice. Objective: This study aims to enhance the recognition efficiency of Chinese herbal pieces using deep learning technology, while addressing the limitations of traditional manual classification methods in terms of both quality and efficiency. Methods: A comprehensive dataset containing 201 types of Chinese herbal pieces was established. Based on Real-time Detection Transformer (RT-DETR), we designed and integrated a Feature-focused Diffusion Network (FDN), resulting in an improved model termed RT-DETR-FDN. The proposed FDN includes a Feature-focus Module and a feature diffusion mechanism, enabling the model to capture more extensive feature information from Chinese herbal pieces and diffuse it across multiple detection scales. Results: Experimental results show that RT-DETR-FDN achieved a precision of 0.925, a recall of 0.943, and an mAP50-95 of 0.851. In addition, the model was compared with representative You Only Look Once series models commonly used in object detection. Compared with these models, RT-DETR-FDN achieved higher recognition accuracy while maintaining a lightweight architecture. Conclusion: This study integrates deep learning with traditional Chinese medicine, providing a more effective solution for the recognition of Chinese herbal pieces.

Rheumatoid arthritis belongs to arthralgia in the theory of traditional Chinese medicine, with cold dampness obstruction pattern (CDO) and damp heat obstruction pattern (DHO) as the main pattern types. Fine therapeutic effects have been obtained in clinical practice following the differentiation of CDO and DHO. However, suitable animal models are not available currently. For adapting to the clinical diagnosis, as well as carrying out basic research of integrated Chinese and Western medicine and preclinical study on new Chinese medicine in a better way, the “Guidelines for Establishing Animal Models of Rheumatoid Arthritis with Cold Dampness Obstruction Pattern and Damp Heat Obstruction Pattern” (referred to as “Guidelines”) were compiled by our research group in cooperation with renowned experts in clinical, pharmaceutical, zoological, and methodological research fields. According to the theory of disease and syndrome integration, experts standardized the establishment methods for animal models of rheumatoid arthritis with CDO and DHO. The Guidelines were compiled via the nominal group method according to the principle of evidence coming in main place, consensus as the auxiliary, and experience as the references. Contents such as animal species, arthritis induction methods, external stimulation conditions, and assessment indicators were specified in the Guidelines based on the comprehensive evaluation of pathogenesis homology, behavioral phenotypic consistency, and drug therapy predictability between animal models and human diseases. The Guidelines will be applicable to the research on syndromes in rheumatoid arthritis, elucidation of acting mechanism, and development of new medicine, and provide reference for standardizing other types of animal models with the integration of disease and syndrome, to promote the modernization of Chinese medicine research.

Objective: To evaluate the in vitro procoagulant efficacy and in vivo potential thrombogenic risk of self-prepared activated prothrombin complex concentrate (aPCC). Methods: The preparation was administered at a dose of 0.5 IU per milliliter of plasma. For in vitro assays, the self-prepared aPCC concentrate was added to plasma spiked with factorⅧ (FⅧ) inhibitors. Calibrated automated thrombin generation (CAT), prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT), and fibrinogen (Fib) quantification were performed. Normal saline and FEIBA
were set as controls to evaluate the procoagulant capacity of the self-prepared aPCC concentrate. For in vivo animal studies, the self-prepared aPCC concentrate was injected into rats via the jugular vein. A ferric chloride (FeCl3) filter paper patch was applied to induce carotid arterial thrombosis. Laser speckle blood flow imaging was used to continuously monitor thrombus formation in the rat carotid artery. Plasma samples were collected from rats for CAT, PT, APTT, TT and Fib testing, with normal saline and FEIBA
as controls to evaluate the potential thrombogenic risk of the self-prepared aPCC concentrate. Results: Supplementation with aPCC significantly shortened APTT and PT values in inhibitor-spiked plasma (all P<0.001). There were no statistically significant differences in APTT and PT between FEIBA
and self-prepared aPCC (P>0.05). CAT results demonstrated that adding aPCC to inhibitor-containing plasma markedly increased endoge-nous thrombin potential (ETP) and peak thrombin concentration (Peak) (P<0.001), with both parameters higher than those of normal plasma (P<0.05). No significant intergroup difference in ETP was observed between self-prepared aPCC and FEIBA
(P>0.05). Carotid blood flow imaging in rats revealed that, compared with FEIBA
, thrombi induced by self-prepared aPCC were smaller and less stable, and all underwent spontaneous lysis, accompanied by better restoration of carotid blood perfusion. Conclusion: The self-prepared aPCC restores coagulation function in inhibitor-spiked plasma to a comparable extent as FEIBA
, while exhibiting a lower thrombogenic risk.

ObjectiveTo observe the effectiveness and safety of Jiuzihuichun decoction combined with spleen- strengthening moxibustion in patients with asthenospermia infertility with spleen-kidney deficiency pattern. MethodsA total of 82 patients with asthenospermia of spleen-kidney deficiency pattern in Shanghai Seventh People's Hospital were included. The patients were randomly divided into an observation group and a control group, with 41 patients in each group. The control group received oral administration of WuziYanzong pills combined with spleen-strengthening moxibustion. The dosage of Wuzi Yanzong pills was 1 bag each time, and it was taken twice a day. The spleen-strengthening moxibustion was carried out once a week. The observation group, on the other hand, took Jiuzi Huichun decoction orally combined with spleen-strengthening moxibustion. The Jiuzi Huichun Decoction was taken 200 mL each time, twice a day, with one dose in the morning and one in the evening. The spleen-strengthening moxibustion for the observation group was also performed once a week. The treatment course for both groups was 12 weeks, and they were followed up for an additional 12 weeks. During the treatment process,12 cases were either lost to follow-up or excluded. Eventually, 70 cases were available for evaluation,with 35 cases in the control group and 35 cases in the observation group. The pregnancy status of the patients' spouse within 6 months was recorded. The traditional Chinese medicine (TCM) syndrome scores of spleen-kidney deficiency pattern before and after treatment were evaluated. The semen volume,semen routine parameters,normal sperm morphology,sperm DNA fragmentation index,seminal plasma fructose,seminal plasma acid phosphatase, and seminal plasma α-glucosidase levels of the two groups were detected before and after treatment. In addition, the safety indicators related to liver and kidney functions of the two groups were detected before and after treatment. ResultsDuring the 6-month observation period, when compared with the situation before treatment in their respective groups,the semen volume of the observation group and the control group increased. In contrast, the sperm concentration,sperm motility,proportion of a+b-grade sperm,normal sperm morphology,seminal plasma fructose,seminal plasma acid phosphatase,seminal plasma α-Glucosidase,the proportion of a-grade sperm,linear sperm motility,linear sperm concentration, and linear sperm count all increased significantly(P<0.05). At the same time, the sperm DNA fragmentation index and the TCM syndrome scores of the spleen-kidney deficiency pattern decreased significantly(P<0.05). When the observation group was compared with the control group after treatment, the clinical efficacy of the observation group was better(Z=-2.276,P<0.05). The pregnancy rate of the observation group's spouses was 14.3%,which was higher than the 2.9% of the control group. The sperm motility, the proportion of a+b-grade sperm,seminal plasma fructose,the proportion of a-grade sperm,normal sperm morphology,α-glucosidase, and linear sperm motility in the observation group were higher than those in the control group (P<0.05). Moreover, the sperm DNA fragmentation index and the TCM syndrome scores of spleen-kidney deficiency pattern in the observation group were lower than those in the control group (P<0.01). No serious adverse reactions occurred in the two groups,and no abnormalities were found in the safety indicators after treatment. ConclusionJiuzi Huichun decoction combined with spleen-strengthening moxibustion can enhance sperm viability and sperm concentration. It can also improve the TCM-related symptoms of asthenospermia of spleen-kidney deficiency pattern and sperm morphology. Additionally, it can reduce the sperm DNA fragmentation index and regulate the level of seminal plasma bioenzyme in patients with male asthenospermia infertility of spleen-kidney deficiency pattern. Therefore, it is worthy of further promotion and application in clinical practice.

To compare the clinical efficacy of intralesional corticosteroid injection combined with topical corticosteroids versus topical corticosteroids alone in patients with idiopathic granulomatous mastitis (IGM). Patients diagnosed with IGM and treated at the Breast Surgery Department of Peking Union Medical College Hospital between October 2016 and March 2018 were retrospectively analyzed. Based on treatment modalities, patients were divided into an injection group (receiving intralesional corticosteroid injections plus topical corticosteroids) and a control group (receiving topical corticosteroids alone). Clinical outcomes and recurrence rates were compared between the two groups. Seventy-eight patients meeting the inclusion and exclusion criteria were enrolled, with 51 in the injection group and 27 in the control group. The median age was 35 years (range: 22-45). The maximum lesion diameter was 8.7±2.9 cm in the injection group and 7.1±2.7 cm in the control group. Compared with the control group, the injection group showed a significantly shorter time to half remission(2.8±0.9 weeks Compared with topical corticosteroid monotherapy, the combina-tion of intralesional corticosteroid injection and topical corticosteroids provides faster symptom control and shorter treatment duration while maintaining high efficacy and low long-term recurrence rates, offering a more effective therapeutic option for IGM patients.
