The chapter Zhouyu in Guoyu says "Qi of the heaven and the earth moves without losing its order." With lucidity ascending and turbidity descending, Qi moves in a normal state, and Yin and Yang consolidate the foundation of the body. The mutual interference between lucidity and turbidity leads to the disorder of Qi movement, thus causing diseases. It is a pathological state of disorder between ascending and descending, as well as between entering and exiting, gradually evolving into a state of turbidity affecting lucidity and transforming into pathogen, which can be used to interpret and analyze the core of disease pathogenesis. The theory of lucidity and turbidity is connected with the harmony of nutrient and defensive aspects, Qi circulation, and sweat pore associating with Qi movement, and it has common implications with immune responses and nutrient metabolism system, intestinal mucosal barrier function, and mitochondrial energy synthesis. Modern studies have shown that intestinal flora imbalance, bile acid receptor inactivation, macrophage polarization imbalance, epithelial-mesenchymal transition, ferroptosis and other related microscopic pathological mechanisms are involved in the development and progression of ulcerative colitis. By delving into the common meaning of the classic theory of mutual interference between lucidity and turbidity in traditional Chinese medicine and modern medical pathological mechanisms, this paper summarizes the correspondence between the micropathological mechanism and the theory of mutual interference between lucidity and turbidity in the regulation and mamagement of ulcerative colitis. The combined use of sweet and warm medicinal materials consolidates the middle Qi and activates Qi circulation, thus ascending lucidity and descending turbidity. The combined use of pungent medicinal materials for dispersing and bitter medicinal materials for descending simultaneously raises warm and clear Qi. Wind-extinguishing medicinal materials facilitate the ascending of Qi and the opening of sweat pores. Accordingly, turbidity descends and lucidity ascends. The prescriptions incorporating these medication principles are in agreement with the therapeutic approach of following the normal flow of lucidity and turbidity. This paper clarifies the scientific connotation and micropathologic mechanism of ulcerative colitis from the perspective of mutual interference between lucidity and turbidity, providing new theories and prescriptions for the clinical diagnosis, treatment, and prevention of ulcerative colitis.

OBJECTIVE To evaluate the therapeutic effects and safety of everolimus combined with letrozole and conventional chemotherapy for metastatic or recurrent endometrial carcinoma (EC). METHODS The clinical and follow-up data of 156 patients with metastatic or recurrent EC admitted to Nanyang Central Hospital from January 2020 to January 2024 were analyzed retrospectively. They were divided into a control group (77 cases) and an observation group (79 cases) according to different therapeutic regimens. The control group received paclitaxel+carboplatin/cisplatin regimen, and concurrently took Letrozole tablets at a dose of 2.5 mg orally once daily; the observation group took Everolimus tablets 10 mg orally, once a day, in addition to the treatment regimen given to the control group. Each treatment cycle lasted 21 days, and both groups of patients underwent continuous treatment for 6 to 8 cycles. The short-term efficacy indicators (objective response rate and disease control rate), the levels of serum tumor markers [carbohydrate antigen 125, human epididymis protein 4, vascular endothelial growth factor and matrix metalloproteinase-9] and medium- to long-term efficacy indicators [progression-free survival (PFS) and overall survival (OS)] were compared between the two groups. Additionally, the occurrence of toxic and side effects in both groups of patients was recorded. RESULTS The objective response rate (53.16%), disease control rate (89.87%), median PFS (6.47 months) and median OS (10.79 months) of the observation group were significantly higher or longer than those (22.08%, 68.83%, 4.63 months, 8.84 months) of the control group (P<0.05). Compared with before treatment, the levels of serum tumor markers in both groups decreased significantly after 6 cycles of treatment; the above indexes of the observation group were significantly lower than those of the control group (P<0.05). The proportion of patients with stomatitis in the observation group was significantly higher than that of the control group (P<0.05), and there was no statistically significant difference in the proportions of patients experiencing other toxic and side effects, such as leukopenia, between the two groups (P>0.05). CONCLUSIONS The everolimus combined with letrozole and conventional chemotherapy can effectively improve the short-term efficacy and prolong the survival period in patients with metastatic or recurrent EC, but attention should be paid to the occurrence of toxic and side effects, especially stomatitis.

The historical development of endogenous wind (内风) is traced with time as the thread, based on the progression of factors such as syndromes, causes of disease, and pathogenesis. It is believed that the concept of wind syndrome originated in The Inner Canon of Yellow Emperor (《黄帝内经》), encompassing both exogenous wind (外风) and endogenous wind syndrome. Over time, exogenous wind syndrome gradually evolved into mild syndromes and severe syndromes, while endogenous wind syndrome emerged from severe syndromes of exogenous wind. Endogenous wind syndrome has both syndrome and pathogenic attributes, and its theoretical system has gradually become more refined. Based on the theories of ancient and modern medical practitioners, and combining the holistic perspectives with Xiang (象) thinking, it is proposed that endogenous wind has both physiological and pathological distinctions. The physiological endogenous wind refers to the liver's moderate dispersing and regulating function, which helps to distribute qi (气), blood, and body fluids, while pathological endogenous wind arises from abnormal liver dispersal. Therefore, in clinical practice, different treatment methods, such as tonifying, unblocking, and warming, can be applied according to the differentiation of deficiency and excess in the pathogenesis.

The theory of "Yang transforming Qi while Yin constituting form" in the Huangdi's Internal Classic is derived from the application, transformation, movement, and balance of Tao. It is highly condensed, revealing the true meaning of Tao and guiding the changes and progress of all natural things, including diseases. Therefore, the appearance of various physical diseases is the manifestation of Yin-Yang Qi transformation. Sweat pore, formed by the Qi transformation of Yin and Yang, is the nourishing and regulating system. It serves as the hub and channel, assisting in the flow and transformation of Qi, facilitating the exchange of material, energy, and information with the outside world. With sweat pore as the hub and based on the macro-control and holistic thinking of "Yang transforming Qi while Yin constituting form", this paper explores the microscopic mechanisms underlying chronic liver disease. In combination with the roles of mitochondria, exosomes, and the ultraliver sieve structure in the formation and progression of chronic liver disease, this paper elucidates the close internal relationship between the disease's initial quality, symptom signs, and its physiological and pathological functions under the guidance of this theory. Modern studies have shown that autophagy, intestinal flora disorders, glucose and lipid metabolism disturbances, activation of inflammatory factors, ferroptosis, and other microscopic pathological mechanisms are involved in the occurrence and development of chronic liver disease. The common connotation of the Yin-Yang concept in traditional Chinese medicine (TCM) and the pathological mechanisms in modern medicine is deeply analyzed. The corresponding relevant microscopic mechanisms and the guiding role of the theory of "Yang transforming Qi while Yin constituting form-sweat pore" in the management of chronic liver disease are summarized. Wind medicine promotes growth and transformation through sweat pore. The combination of pungent and sweet medicines facilitates Yang and disperse Yin. The formulas, combining the characteristics of wind medicine and pungent and sweet medicines, fit the principle of "Yang transforming Qi while Yin constituting form-sweat pore". This paper combines both macro and micro perspectives to explain the scientific connotation and microscopic mechanisms of chronic liver disease based on the theory of "Yang transforming Qi while Yin constituting form-sweat pore", and explore the prevention and treatment of chronic liver disease through the principles, methods, prescriptions, and medicines featured by combination of pungent and sweet medicines, facilitating Yang, activating sweat pore, and dispersing Yin, providing new ideas and reference for the clinical treatment of chronic liver disease.

Traditional Chinese medicine (TCM) represents a paradigmatic approach to personalized medicine, developed through the systematic accumulation and refinement of clinical empirical data over more than 2000 years, and now encompasses large-scale electronic medical records (EMR) and experimental molecular data. Artificial intelligence (AI) has demonstrated its utility in medicine through the development of various expert systems (e.g., MYCIN) since the 1970s. With the emergence of deep learning and large language models (LLMs), AI's potential in medicine shows considerable promise. Consequently, the integration of AI and TCM from both clinical and scientific perspectives presents a fundamental and promising research direction. This survey provides an insightful overview of TCM AI research, summarizing related research tasks from three perspectives: systems-level biological mechanism elucidation, real-world clinical evidence inference, and personalized clinical decision support. The review highlights representative AI methodologies alongside their applications in both TCM scientific inquiry and clinical practice. To critically assess the current state of the field, this work identifies major challenges and opportunities that constrain the development of robust research capabilities-particularly in the mechanistic understanding of TCM syndromes and herbal formulations, novel drug discovery, and the delivery of high-quality, patient-centered clinical care. The findings underscore that future advancements in AI-driven TCM research will rely on the development of high-quality, large-scale data repositories; the construction of comprehensive and domain-specific knowledge graphs (KGs); deeper insights into the biological mechanisms underpinning clinical efficacy; rigorous causal inference frameworks; and intelligent, personalized decision support systems.

Sensorineural hearing loss is one of the most common sensory disorders. In recent years, auditory neuropathy spectrum disorders caused by mutations in the OTOF gene have garnered significant attention worldwide, marking it as the first deafness gene with breakthroughs in gene therapy. Most patients with OTOF gene mutations present with stable, congenital, or prelingual onset of hearing loss, which can range from severe to profound and even complete hearing loss. However, a minority of patients may exhibit mild to moderate progressive hearing loss or temperature-sensitive hearing loss. This review further explores the genotype-phenotype relationship of the OTOF gene based on reported cases in China and abroad. Additionally, we analyze the characteristics of the natural history of OTOF gene mutations within the Chinese population. This study aims to provide a reference for the clinical diagnosis, evaluation, and treatment of hearing loss associated with OTOF gene mutations.

Metastasis serves as an indicator of malignancy and is a biological characteristic of carcinomas. Epithelial-mesenchymal transition (EMT) plays a key role in the promotion of tumor invasion and metastasis and in the enhancement of tumor cell aggressiveness. Prostaglandin E synthase 3 (p23) is a cochaperone for heat shock protein 90 (HSP90). Our previous study showed that p23 is an HSP90-independent transcription factor in cancer-associated inflammation. The effect and mechanism of action of p23 on lung cancer metastasis are tested in this study. By utilizing cell models in vitro and mouse tail vein metastasis models in vivo, the results provide solid evidence that p23 is critical for promoting lung cancer metastases by regulating downstream CXCL1 expression. Rather than acting independently, p23 forms a complex with RNA-binding motif protein 14 (RBM14) to facilitate EMT progression in lung cancer. Therefore, our study provides evidence for the potential role of the RBM14-p23-CXCL1-EMT axis in the metastasis of lung cancer.

Human self-organizing cardioids, a recent breakthrough in cardiac organoid research, are constructed with the specialized cardiac lineage cells derived from human pluripotent stem cells (hPSCs) and have made rapid advancements since 2021. A key advantage of these organoids is their minimal reliance on external interventions, allowing them to more accurately replicate the heart's developmental processes through intrinsic signaling pathways, thereby closely mimicking natural cardiac characteristics. Consequently, they hold significant promise for improving drug safety evaluations, treating both congenital and acquired heart diseases, advancing eugenics practices, developing humanized cardiac disease models, conducting research in regenerative medicine, and understanding how unique environments (such as aerospace) affect human health. This review systematically describes the current various self-organizing cardioid construction techniques, comparing the structural differences caused by diverse signal stimulations, which would be instrumental in optimizing designs for more advanced and mature cardioids. Additionally, we summarize existing applications and address the challenges faced. Despite some uncertainties and challenges in current technologies and applications, this emerging cardiac organoid technology holds promise to provide new possibilities for cardiovascular medicine through continuous refinement.

Chronic visceral pain is a persistent and debilitating condition arising from dysfunction or sensitization of the visceral organs and their associated nervous pathways. Increasing evidence suggests that imbalances in central nervous system function play an essential role in the progression of visceral pain, but the exact mechanisms underlying the neural circuitry and molecular targets remain largely unexplored. In the present study, the ventral tegmental area (VTA) was shown to mediate visceral pain in mice. Visceral pain stimulation increased c-Fos expression and Ca2+ activity of glutamatergic VTA neurons, and optogenetic modulation of glutamatergic VTA neurons altered visceral pain. In particular, the upregulation of NMDA receptor 2A (NR2A) subunits within the VTA resulted in visceral pain in mice. Administration of a selective NR2A inhibitor decreased the number of visceral pain-induced c-Fos positive neurons and attenuated visceral pain. Pharmacology combined with chemogenetics further demonstrated that glutamatergic VTA neurons regulated visceral pain behaviors based on NR2A. In summary, our findings demonstrated that the upregulation of NR2A in glutamatergic VTA neurons plays a critical role in visceral pain. These insights provide a foundation for further comprehension of the neural circuits and molecular targets involved in chronic visceral pain and may pave the way for targeted therapies in chronic visceral pain.

Ursodeoxycholic acid (UDCA) is a naturally occurring, low-toxicity, and hydrophilic bile acid (BA) in the human body that is converted by intestinal flora using primary BA. Solute carrier family 7 member 11 (SLC7A11) functions to uptake extracellular cystine in exchange for glutamate, and is highly expressed in a variety of human cancers. Retroperitoneal liposarcoma (RLPS) refers to liposarcoma originating from the retroperitoneal area. Lipidomics analysis revealed that UDCA was one of the most significantly downregulated metabolites in sera of RLPS patients compared with healthy subjects. The augmentation of UDCA concentration (≥25 μg/mL) demonstrated a suppressive effect on the proliferation of liposarcoma cells. [15N2]-cystine and [13C5]-glutamine isotope tracing revealed that UDCA impairs cystine uptake and glutathione (GSH) synthesis. Mechanistically, UDCA binds to the cystine transporter SLC7A11 to inhibit cystine uptake and impair GSH de novo synthesis, leading to reactive oxygen species (ROS) accumulation and mitochondrial oxidative damage. Furthermore, UDCA can promote the anti-cancer effects of ferroptosis inducers (Erastin, RSL3), the murine double minute 2 (MDM2) inhibitors (Nutlin 3a, RG7112), cyclin dependent kinase 4 (CDK4) inhibitor (Abemaciclib), and glutaminase inhibitor (CB839). Together, UDCA functions as a cystine exchange factor that binds to SLC7A11 for antitumor activity, and SLC7A11 is not only a new transporter for BA but also a clinically applicable target for UDCA. More importantly, in combination with other antitumor chemotherapy or physiotherapy treatments, UDCA may provide effective and promising treatment strategies for RLPS or other types of tumors in a ROS-dependent manner.
