OBJECTIVE To investigate the mechanism by which the traditional Chinese medicine formula Xibining Ⅱ modulates cold-stimulus pain sensitivity in rats with cold-damp obstruction-type knee osteoarthritis (KOA) based on the SET domain bifurcated histone lysine methyltransferase 2 (SETDB2)/histone H3 lysine 9 trimethylation (H3K9me3) signaling axis. METHODS Fifty SD rats were randomly divided into control group (intragastric administration and intrathecal injection of equal volumes of normal saline), model group (intragastric administration and intrathecal injection of equal volumes of normal saline), Xibining Ⅱ low- and high-dose groups (4, 8 g/kg Xibining Ⅱ, intragastric administration), and high-dose of Xibining Ⅱ+small interfering RNA (siRNA) group (8 g/kg of Xibining Ⅱ via intragastric administration and intrathecal injection of SETDB2 siRNA at 0.2 mmol/L, 20 μL per rat), with 10 rats in each group. Except for the control group, cold-damp obstruction-type KOA model was induced in other groups. Drug administration commenced 14 days post-modeling and continued for 28 days. Following the final administration, the following were assessed: behavioral changes in cold-stimulation pain sensitivity, histopathological changes in the articular cartilage of the knee joint, the contents of inflammatory factors [tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β)] and pain mediators [calcitonin gene-related peptide (CGRP), nerve growth factor (NGF)], as well as the expressions of SETDB2/H3K9me3 signaling axis,inflammatory factors and pain mediators related proteins and mRNAs in dorsal root ganglion (DRG) tissue. RESULTS After 28 days of drug administration, compared with the model group, Xibining Ⅱ low- and high-dose groups exhibited significantly prolonged cold-stimulus paw withdrawal latency (P<0.05); the number of positive responses in the acetone low-temperature test was significantly reduced (P<0.05); Mankin score and the Osteoarthritis Research Society International score for knee joint tissue, as well as the levels of inflammatory factors and pain mediators in the serum and their expression in DRG tissue were all significantly decreased (P<0.05); the protein expressions of SETDB2 and H3K9me3 in DRG tissue were significantly increased (P<0.05). Intrathecal injection of SETDB2 siRNA reversed the above effects of high-dose of Xibining Ⅱ (P<0.05). CONCLUSIONS Xibining Ⅱ may alleviate inflammatory and pain responses by activating the SETDB2/H3K9me3 signaling axis, ultimately improving cold-stimulus pain sensitivity in rats with cold-damp obstruction-type KOA.

As one of the most common malignant tumors, digestive system tumors exhibit an increase in the incidence and mortality year by year. Its pathogenesis is complex, making it difficult to carry out early prevention. Autophagy is a process in which cells use lysosomes to degrade their organelles and macromolecules to maintain cellular homeostasis under the regulation of autophagy-related genes. Cellular autophagy has a dual regulatory effect on the tumor microenvironment, which always affects the occurrence and development of digestive system tumors. Therefore, the effect and mechanism of action of cellular autophagy on digestive system tumors have become a hot topic in tumor therapy in recent years. Meanwhile, the remarkable research results of targeted autophagy drugs indicate that cellular autophagy may become an important target for anti-digestive system tumors. Traditional Chinese medicine (TCM) has been widely used in the comprehensive treatment of digestive system tumors with good efficacy. A variety of active ingredients in TCM, such as flavonoids, glycosides, terpenoids, quinones, and alkaloids, can increase the expression of autophagy-associated proteins microtubule-associated protein 1 light chain 3 (LC3)Ⅱ/Ⅰ, autophagy-related gene (ATG)5, ATG7, inhibit the expression of autophagy-related protein p62 , and induce autophagy in digestive system tumor cells, thereby exerting the anti-digestive system tumor effect. By summarizing the research results in recent years on the modulation of cell autophagy by active ingredients in TCM to fight against digestive system tumors, this paper analyzed the relevant signaling pathways, regulatory factors, and functional characteristics of cell autophagy modulation, so as to elucidate the mechanism by which active ingredients of TCM induce autophagy and to provide ideas and references for clinical application.

ObjectiveTo investigate the possible mechanism of action of Xibining Formula (膝痹宁) for cartilage damage in knee osteoarthritis (KOA) through the cyclic guanosine-adenosine monophosphate synthase (cGAS)- stimulator of interferon genes (STING) signaling pathway. MethodsFifty C57BL/6J mice were randomly divided into five groups (10 per group), sham operation group, KOA model group, low-dose Xibining Formula group, high-dose Xibining Formula group, and high-dose Xibining Formula + agonist group. The KOA models were constructed using the destabilization of the medial meniscus (DMM) method in all groups but the sham surgery group. Two weeks after surgery, the low- and high-dose Xibining Formula groups were administered Xibining Formula at doses of 3.58 g/(kg·d) and 14.32 g/(kg·d) respectively via gavage. The high-dose Xibining Formula + agonist group received 14.32 g/(kg·d) of Xibining Formula via gavage followed by an intraperitoneal injection of Vadimezan (DMXAA) at 25 mg/kg. The sham surgery group and the KOA model group mice were given an equivalent volume of normal saline at 5 ml/(kg·d) via gavage, once daily for four consecutive weeks. Serum levels of tumor necrosis factor-alpha (TNF-α), interleukin-1β (IL-1β), and interleukin-6 (IL-6) were measured by ELISA; pathological changes in cartilage tissue were observed using hematoxylin-eosin (HE) staining and Safranin O-Fast Green staining. Pathological changes were scored according to the Mankin scoring system; the levels of cartilage tissue matrix regulation-related indicators such as matrix metalloproteinase 3 (MMP3), matrix metalloproteinase 13 (MMP13), a disintegrin and metalloproteinase with thrombospondin motifs 5 (ADAMTS), type-Ⅱ collagen (CⅡ) and aggregated proteoglycan (Aggrecan), and also cGAS-STING pathway-related protein and mRNA expression levels were detected by Western blot and qPCR methods. ResultsCompared with the sham surgery group, the KOA model group showed severe cartilage edge destruction, significantly increased Mankin scores, significantly decreased protein and mRNA expression levels of COLⅡ and Aggrecan, and significantly increased protein and mRNA expression levels of cGAS, STING, MMP3, MMP13, and ADAMTS5 (P<0.01). Compared with the control group, serum level of IL-6, IL-1β, TNF-α in all the intervented groups decreased (P<0.01), while compared with high-dose Xibining Formula group, level of IL-6, IL-1β, and TNF-α in low-dose Xibining Formula group and high-dose Xibining Formula + agonist group increased (P<0.01). Compared with the KOA model group, all the intervention groups exhibited alleviated cartilage pathological changes, signi-ficantly reduced Mankin scores, significantly increased protein and mRNA expression levels of COLⅡ and Aggrecan, and significantly decreased protein and mRNA expression levels of cGAS, STING, MMP3, MMP13, and ADAMTS5 (P<0.01). Compared with high-dose Xibining Formula group, high-dose Xibining Formula + agonist group showed cartilage edge destruction, significantly increased Mankin scores, significantly decreased protein and mRNA expression levels of COLⅡ and Aggrecan, and increased protein and mRNA expression levels of cGAS, STING, MMP3, MMP13, and ADAMTS5 (P<0.01). ConclusionXibining Formula may improve KOA cartilage damage by inhibiting the cGAS-STING signaling pathway, decreasing matrix degradation-related proteins, and elevating matrix composition-related proteins.

With the increasing incidence and mortality of malignant tumors year by year, the prevention and treatment of malignant tumors has become a hot field of research. Although the existing anti-tumor treatment methods such as surgery, radiotherapy, chemotherapy, immunity and targeting have achieved some results, there are also obvious shortcomings, which are not conducive to the improvement of patients' quality of life and long-term treatment. Therefore, seeking a new efficient and safe treatment has become a hot topic of concern for many oncologists. adenosine monophosphate activated protein kinase(AMPK)/mammalian target of rapamycin(mTOR) signaling pathway can participate in intracellular energy metabolism and affect the pathogenesis and outcome of tumors through multiple mechanisms. It is widely mentioned in the occurrence and development of many tumors. The activity level of this pathway is closely related to the abnormal proliferation and invasion of tumor cells, and is considered as an important pathway for anti-tumor therapy research. The anti-tumor treatment of traditional Chinese medicine(TCM) has significant advantages such as syndrome differentiation and treatment and sample consideration. The study found that flavonoids, alkaloids, polyphenols, saponins and other active components of traditional Chinese medicine, as well as the traditional Chinese medicine compound Xiangbei San, Yiqi Fuzheng Jiedu decoction, Yiqi Fuzheng prescription, etc can activate the AMPK/ mTOR signaling pathway by regulating the expression of AMPK/mTOR signaling pathway and upstream and downstream proteins, thereby inducing tumor cell autophagy and apoptosis, inhibiting tumor angiogenesis and epithelial mesenchymal transformation, regulating aerobic glycolysis and energy metabolism, and reversing drug resistance to exert anti-tumor effects. In this paper, by summarizing the research achievements of TCM anti-tumor in recent years, the specific mechanism of action of TCM regulating AMPK/ mTOR signaling pathway against tumor was discussed, aiming to provide ideas and references for the research and development of anti-tumor new drugs.

As a common malignant tumor of the respiratory system, the incidence and mortality of lung cancer are still rising year by year. Its pathogenesis is complex, the prognosis is poor, and it seriously affects human physical and mental health. Although existing Western medical treatments can inhibit tumor growth to a certain extent and relieve patients' painful symptoms, problems such as postoperative recurrence and metastasis, numerous adverse reactions, and the tendency to develop drug resistance make the overall therapeutic effect unsatisfactory. Therefore, it is urgent to seek more efficient and safer treatments. Adenosine monophosphate-activated protein kinase (AMPK) signaling pathway can regulate the growth, differentiation, apoptosis, and autophagy of lung cancer cells, and is extensively involved in the occurrence and development of lung cancer, thus being regarded as an important target for anti-lung cancer therapy. Traditional Chinese medicine (TCM) exerts anti-lung cancer effects through multiple pathways, mechanisms, and targets, with advantages such as preventing postoperative recurrence and metastasis, alleviating the adverse reactions of radiotherapy and chemotherapy, and improving quality of life. TCM has therefore become a key approach in current anti-lung cancer treatment. Studies have found that active components of Chinese medicine, including flavonoids, saponins, polyphenols, and terpenes, as well as Chinese medicine compound prescriptions such as Guiqi Yiyuan extract, Qingzao Jiufei decoction, and Yiqi Fuzheng formula, have significant regulatory effects on AMPK and its interacting signaling pathways. These effects include inducing autophagy and apoptosis of lung cancer cells, modulating macrophage polarization, inhibiting epithelial-mesenchymal transition, reversing drug resistance, and blocking the cell cycle, thereby exerting anti-lung cancer activity. This article reviews and summarizes recent studies on the anti-lung cancer effects of TCM, and discusses the mechanisms by which TCM regulates the AMPK signaling pathway in the treatment of lung cancer, with the aim of providing ideas and references for the development of new clinical anti-lung cancer drugs.

Gastrointestinal tumors (GTs), including colorectal cancer, gastric cancer, liver cancer, pancreatic cancer, and esophageal cancer, are increasing in incidence worldwide and have become one of the major diseases threatening human health. Tumor stem cells (TSCs), an undifferentiated subpopulation within tumor tissues, possess biological characteristics such as self-renewal, multidirectional differentiation, high tumorigenicity, and resistance to radiochemotherapy. They play an important role in the occurrence, progression, recurrence, and metastasis of GTs and have increasingly become a research hotspot in GT treatment. Although modern medicine has made remarkable progress, there remain many problems in therapeutic approaches targeting TSCs. In this context, traditional Chinese medicine (TCM), with its favorable safety profile and multi-target mechanisms, has shown potential advantages and value in regulating TSCs. It can reduce TSC drug resistance, enhance the sensitivity of tumor cells to chemotherapeutic agents, inhibit tumor growth and metastasis, and has shown unique advantages in improving the quality of life and prolonging the survival of GT patients. Studies have found that active components of Chinese medicine, such as terpenoids, polyphenols, flavonoids, glycosides, and quinones, and Chinese medicine compound formulas, including Zuojin pills, Sijunzi decoction, Biejiajian pills, and Xuanfu Daizhe decoction, can inhibit TSCs-related signaling pathways such as the Notch signaling pathway, the Wnt/β-catenin signaling pathway, the phosphatidylinositol 3-kinase/protein kinase B (PI3K/Akt) signaling pathway, and the Hippo signaling pathway. They also reduce the expression of TSC surface markers, including sex-determining region Y-box 2 (SOX2), sex-determining region Y-box 9 (SOX9), octamer-binding transcription factor 4 (OCT4), prominin-1 (CD133), cluster of differentiation 44 (CD44), cluster of differentiation 24 (CD24), and thyroid transmembrane protein 1 (CD90), thereby hindering TSC differentiation, accelerating their metabolic processes, improving the tumor microenvironment, and consequently inhibiting GT growth. This study collects and analyzes recent research on the regulation of TSCs by TCM in the treatment of GT, aiming to provide a new theoretical basis for tumor therapy with TCM, expand its application in the comprehensive treatment of GT, and offer new therapeutic ideas and methods for clinical practice.
