RESUMO

In recent years, polysaccharides have received much attention because of their high safety and good immunological activity. The study of polysaccharide in vivo process is a key scientific problem that needs to be solved for polysaccharide drug development. Some progress has been made in the field of polysaccharide pharmacokinetics and immunomodulation. However, due to the lack of both chromogenic and light-absorbing groups and the complex molecular structure of polysaccharides, the in vivo processes and immunomodulatory mechanisms of polysaccharides have been slow to be investigated. The effective combination of multiple techniques can break the bottleneck of difficult tracing and unknown immunomodulatory mechanism of polysaccharides in vivo, and promote the development and utilization of polysaccharides. In this paper, we systematically summarize the key techniques in the study of polysaccharide in vivo processes and immunomodulatory mechanisms in order to provide technical references and research ideas for the study of polysaccharide in vivo processes and immunomodulatory mechanisms.

RESUMO

In this paper, the antitussive and expectorant activity of platycodin D (PD) were studied by constructing a mouse cough induced by concentrated ammonia water and a mouse trachea phenol red excretion model. The mechanism of antitussive and expectorant effect of PD was studied by metabolomics. The animal experiment was approved by the Animal Ethics Committee of Jiangxi University of Chinese Medicine (approval number: JZLLSC-20220739). Then mice were randomly divided into the normal, model, positive drug, PD low-dose, PD medium-dose and PD high-dose group. The antitussive and expectorant effects of PD were evaluated using a cough mouse model induced by concentrated ammonia water and a mouse tracheal phenol red excretion model, respectively. UHPLC-LTQ-Orbitrap-MS was used to identify the metabolites of mouse lung tissue, and multivariate statistical analysis method of orthogonal partial least squares discriminant analysis (OPLS-DA) was used for metabolites profile analysis. The differential metabolites were screened by variable projected importance value (VIP) and t-test results. Pathways for enrichment of differentiated metabolites were analyzed using the MetaboAnalyst platform. The comparative method was applied to analyze the differences in mechanisms of PD, Deapio-platycodin D (DPD) and total platycosides fraction. The results showed that PD at different concentrations could significantly prolong (P < 0.05) the incubation period of cough mice induced by ammonia water, reduce the coughs frequency, and significantly increase (P < 0.05) the amount of phenol red excretion in phenol red excretion model mice. PD could regulate 6 metabolic pathways of phenylalanine, tyrosine and tryptophan biosynthesis, linoleic acid metabolism, phenylalanine metabolism, glycerophospholipid metabolism, and tyrosine metabolism to exert antitussive effect. It could also regulate 8 metabolic pathways of linoleic acid metabolism, glyoxylic acid and dicarboxylic acid metabolism, glycerol phospholipid metabolism, citric acid cycle and arachidonic acid metabolism to exert an expectorant effect. However, only linoleic acid metabolism and glycerophospholipid metabolism could be regulated by the PD, total platycosides fraction and DPD, which may be ascribed to the structural difference of the platycosides and the interaction between platycosides and the intestinal microbiota. Functional analysis showed that these metabolic pathways are closely related to the regulatory mechanisms of anti-inflammatory response, immune function regulation, neurotransmitter release, cell signal transduction, energy metabolism and cell apoptosis. This study shows that PD possesses good antitussive and expectorant activities. In addition, the mechanism difference of PD, total platycosides fraction and DPD imply that the apiose in PD and the interaction between PD and intestinal microbiota could exert an important effect on the antitussive and expectorant mechanism of the platycosides.

RESUMO

Gastrointestinal motility disorder is an important cause of digestive system diseases. Patients often suffer from nausea, vomiting, gastric retention, gastroparesis, constipation, and many other symptoms, and their quality of life is seriously reduced. Prokinetic agents are routinely used in clinical practice, but their long-term use is prone to problems such as reduced efficacy and increased adverse reactions. Since the incidence of gastrointestinal diseases has continued to rise globally in recent years, there is an urgent need for clinical development of safe and effective treatment strategies. Aurantii Fructus, a traditional Chinese medicine, has the effect of smoothing Qi and eliminating distention, and it has been used to treat gastrointestinal diseases for thousands of years. In modern clinical practice, it is mainly used for the treatment and auxiliary treatment of various gastrointestinal diseases such as functional dyspepsia, functional constipation, and irritable bowel syndrome. The efficacy is remarkable, and no adverse reactions have been reported at conventional doses. Therefore, it can greatly improve the symptoms of patients with gastrointestinal diseases and improve their quality of life. Modern research has revealed that there are many active components in Aurantii Fructus, among which flavonoids have the highest content and the most types. Flavonoids are the main active components in Aurantii Fructus to regulate gastrointestinal motility. Aurantii Fructus and its active components can affect gastrointestinal hormones, neural pathways, Cajal mesenchymal cells, and other multiple mechanisms. They can adjust gastrointestinal motility and correct gastrointestinal motility disorders, showing potential application value in the treatment of gastrointestinal motility disorders. However, a comprehensive analysis of Aurantii Fructus in this aspect is still lacking. This study summarized the pharmacological activities of active components of Aurantii Fructus extract and its flavonoids, volatile oils, alkaloids, and coumarin on the regulation of gastrointestinal motility and explored the latest research progress on its mechanism. Finally, the adverse reactions of Aurantii Fructus were summarized. It aims to provide a scientific basis for the research and clinical application of Aurantii Fructus and its active components in the regulation of gastrointestinal motility.

RESUMO

Alzheimer's disease is a common central neurodegenerative disease, mainly manifested by cognitive impairment and non-cognitive neuropsychiatric symptoms that severely affect patients' daily life and behavioral functioning. The pathogenesis of Alzheimer's disease is still unclear, and the western medicine currently used to treat Alzheimer's disease is only symptomatic, with a single pathway, limited efficacy, and many side effects. In recent years, with the deepening of research on Alzheimer's disease, the study and application of traditional Chinese medicine (TCM) in the treatment of Alzheimer's disease have gradually increased. Several studies have shown that TCM and its effective components can exert anti-Alzheimer's disease effects by regulating molecular mechanisms such as pathological protein production and aggregation, oxidative stress, neuroinflammation, ferroptosis, mitochondrial dysfunction, neurogenesis and neurotransmission, and brain-gut axis. This paper summarized the research progress of TCM in the treatment of Alzheimer's disease in recent years, so as to provide a reference for further study of the specific mechanism of TCM in the prevention and treatment of Alzheimer's disease and the discovery of effective components of TCM.

RESUMO

Cancer, one of the deadliest diseases caused by cells escaping homeostasis, abnormal proliferation, and abnormal differentiation, is fast becoming one of the most burdensome diseases of this century. With decades of human research and cognitive changes in cancer, cancer treatment is also developing rapidly, but there is still a lack of effective treatment and countermeasures. Especially, the search for safe, efficient, and non-toxic drugs has become a long-term goal in the field of cancer. Saponins extracted and separated from traditional Chinese medicine can improve cancer through various pathways and have almost no toxic side effects. Therefore, the research on the anti-cancer effect of saponins is heating up. It is found that saponins play anti-tumor roles by inhibiting proliferation, metastasis, and angiogenesis of cancer cells, promoting apoptosis of cancer cells, inducing autophagy of tumor cells, and regulating miRNA expression and immune functions. Chinese herbal medicine saponins can regulate secretory glycoprotein /β-catenin (Wnt/β-catenin), adenylate activated protein kinase (AMPK), nuclear transcription factor-κB (NF-κB), mitogen-activated protein kinase (MAPK), phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt)/mammalian target of rapamycin (mTOR), Janus kinase/activator of signal transduction and transcription 3 (JAK/ STAT3), hypoxia-inducible factor-1α (HIF-1α), Toll-like receptor (TLR), and other related signaling pathways to get involved in the proliferation, metastasis, angiogenesis, apoptosis, autophagy, and other processes of cancer cells, thus interfering with the progression of cancer. Therefore, the focus of this review is to update the discovery and evaluation of Chinese herbal medicine saponins with anti-cancer properties, clarify their mechanism of action, including the progress of related signaling pathways, and deepen the understanding of the anti-cancer function of Chinese herbal medicine saponins, so as to provide a new perspective and direction for the prevention and treatment of tumors by traditional Chinese medicine and better promote the development and utilization of resources.

RESUMO

Parkinson's disease (PD) is a common neurological degenerative disease in the middle-aged and elderly, characterized by pathological changes of progressive degeneration of dopaminergic neurons in the substantia nigra and Lewy body formation, with high prevalence and long course of disease. The drug is mainly used to treat PD in western medicine, and the early curative effect is remarkable. However, with the progression of the disease and the long-term use of the drug, the efficacy will be significantly reduced, or there may be sports complications, and the long-term efficacy is not good. As a traditional medical system, traditional Chinese medicine has a unique understanding of PD. Traditional Chinese medicine plays an important role in the treatment of PD, which is natural, mild, safe, and effective, and it can cooperate with western medicine to enhance its efficacy and reduce the adverse reactions of western medicine. The pathogenesis of PD is complex, involving multiple levels such as mitochondrial dysfunction and apoptosis. Neuroinflammation is also involved in the progressive degeneration of dopaminergic neurons in PD. The Toll-like receptor 4 (TLR4)/nuclear factor-κB (NF-κB) signaling pathway is a classic inflammatory pathway, and its expression changes play an important role in the occurrence and development of inflammatory response in the body. In recent years, the research on this pathway in TCM is increasing. This paper summarized the literature of traditional Chinese and western medicine in the past 10 years and reviewed the relevant mechanism of TCM regulation of TLR4/NF-κB pathway in the treatment of PD from the aspects of TCM monomer, compound, and other TCM therapies, so as to provide some references for the search for new targets of drug therapy and gene therapy and the in-depth study of TCM prevention and treatment of PD.

RESUMO

Mesenchymal stem cells (MSCs) are self-regenerating, rapidly proliferating pluripotent stem cells that depend primarily on their derived pro-angiogenic, inflammatory regulatory, and trophic factors to exert beneficial effects that attenuate deleterious inflammatory responses, reduce vascular damage, and promote tissue repair and regeneration. Obstructive sleep apnea hypoventilation syndrome (OSAHS) is a chronic disorder marked by oropharyngeal collapse during sleep, resulting in transient reduced airflow, large fluctuations in intrathoracic pressure, and intermittent hypoxia and hypercapnia. OSAHS subsequently cytokine-mediated inflammatory cascades, oxidative stress, and ischemia, recruit MSCs from inflamed and damaged tissues through MSCs-derived of anti-inflammatory and pro-angiogenic factor activity, reduce hypoxia, suppress inflammation, promote regeneration, and prevent fibrosis in OSAHS-injured tissues. In this paper, we will describe the pathogenesis of inflammation, oxidative stress, fibrosis and ischemia from the perspective of OSAHS, highlighting the current research progress on MSCs-dependent regulation of OSAHS-related pathology.

RESUMO

Arsenic, a naturally occurring metal-like chemical element, is one of the 10 chemicals of major public concerns listed by the World Health Organization as harmful to the environment and human health. It can enter the human body through breathing, intaking food, drinking water, skin exposure, and other ways, and long-term exposure to arsenic can cause cancer of multiple organs and impaired function of multiple systems. Epigenetic mechanisms play an important role in arsenic-induced health effects, and research suggested that the carcinogenicity of arsenic may be associated with epigenetic changes. Previous studies focused on the effects of arsenic on DNA methylation modification. In recent years, research showed that 5-hydroxymethylcytosine (5-hmC), an intermediate of active demethylation of DNA, can act as a sensitive epigenetic mark and play a crucial role as a "bridge" between arsenic exposure and health effects. Based on the latest research progress on the role of DNA hydroxymethylation in the health effects associated with arsenic exposure, this article briefly described the relationship between the health effects of arsenic exposure and DNA hydroxymethylation, summarized the possible mechanisms of DNA hydroxymethylation in the health effects associated with arsenic exposure, and provided a scientific basis for preventing and treating the health effects associated with arsenic exposure.

RESUMO

Ferroptosis, a new form of programmed cell death different from apoptosis, necrosis, and autophagy, is closely associated with a variety of physiological and pathological processes. Iron-mediated accumulation of reactive oxygen species is the main inducement of ferroptosis, the mechanism of which is related to intracellular lipid metabolism, iron metabolism, and antioxidant defense pathways. Multiple signaling axes and regulators jointly regulate the occurrence and disruption of ferroptosis. Studies have demonstrated that ferroptosis regulates the growth and proliferation of tumor cells. Inducing ferroptosis in tumor cells can control the growth, metastasis, and multi-drug resistance of tumors. Therefore, the effect and mechanism of ferroptosis on tumor cells have become a hot topic in anti-cancer research. As the research advances, a variety of ferroptosis inducers has been used in the clinical chemotherapy for cancers and demonstrate significant efficacy. Accordingly, the development of ferroptosis-inducing anticancer drugs has become a new research direction for tumor treatment. Some active ingredients such as lycorine, oleanolic acid, dihydroartemisinin, pseudolaric acid B, and ophiopogonin B of Chinese medicines can induce ferroptosis in tumor cells via lipid metabolism, iron metabolism, system Xc-, and GPX4/GSH to regulate the development of tumors, demonstrating a promising prospect in clinical treatment. Based on the theory of the mechanism of ferroptosis, this paper reviews the research progress in ferroptosis induced by active ingredients of Chinese medicines in tumor cells and describes the metabolic regulatory network of ferroptosis from signaling pathways and regulatory factors, providing new strategies for applying active ingredients of Chinese medicines in the treatment of tumors.

RESUMO

According to the latest global cancer statistics, the incidence and mortality of lung cancer rank first in China. Classical therapies remain the most common cancer treatment options, such as surgical resection, radiotherapy, and chemotherapy, but not all cancer patients respond to classical therapies, which require new lung cancer treatment strategies. After decades of research and development, cancer immunotherapy has achieved certain curative effect, which provides new possibilities for cancer treatment. Cyclic guanosine monophosphate-adenosine monophosphate synthase (cGAS) is a cytosolic DNA sensor. It can induce protective immune defense responses against various DNA-containing pathogens and provide anti-tumor immunity by activating the interferon (IFN) gene stimulator (STING) protein. At present, relevant researchers in China and abroad have done a lot of research on the occurrence and development of lung cancer and the pathophysiological mechanism of drug intervention in the treatment of lung cancer. The results show that cGAS/STING signaling pathway plays an important role in the development of the disease, and traditional Chinese medicine monomers or compounds can intervene in lung cancer cells by regulating the cGAS/STING signaling pathway, induce their autophagy and death, regulate their cycle operation, promote senescence, inhibit their proliferation and tumor angiogenesis, promote their invasion and metastasis, and promote the immune activation of anti-lung cancer cells, so as to inhibit or delay the occurrence and development of lung cancer. In recent years, the related research results have been updated rapidly, and the previous literature has not included the latest research results in time, which causes a lot of inconvenience for many scholars to search the literature. Based on this, this paper mainly summarized the mechanism of cGAS/STING signaling pathway intervention in lung cancer in China and abroad in recent years, as well as the research progress of related traditional Chinese medicine intervention, so as to provide new ideas for the development of lung cancer in molecular biology, drug treatment research, and clinical new drug research and provide a reference for further mechanism research.

RESUMO

Tendon-bone healing is a complex biological process. Multiple signaling pathways are involved in tendon-bone healing, including transforming growth factor-β signaling pathway, bone morphogenetic protein signaling pathway, Wnt signaling pathway, fibroblast growth factor signaling pathway and nuclear transcription factor-κB signaling pathway. This paper summarizes the research status of traditional Chinese medicine regulating related signaling pathways to promote tendon-bone healing. It is found that a variety of traditional Chinese medicine monomers or herbal extracts (such as baicalein, icariin, total flavonoids of Drynaria fortunei, parthenolide, total saponins of Panax notoginseng, etc.) and traditional Chinese medicine compounds (such as Taohong siwu decoction, Liuwei dihuang pill, Xujin jiegu liquid, etc.) can promote bone formation, anti-inflammatory, anti-oxidation, by regulating the above signaling pathways, thereby effectively promoting tendon-bone healing.

RESUMO

Bladder cancer (BCa) is the most common malignant tumor of the urinary system, and its incidence is increasing year by year. At present, for all patients with resectable non-metastatic muscle-invasive BCa, radical cystectomy + bilateral pelvic lymph node dissection is strongly recommended, but they still face the risk of recurrence, metastasis and death. In recent years, the proportion of patients with advanced and metastatic BCa is increasing among patients with newly diagnosed BCa. Although current treatment models are diverse, they often struggle to achieve significant efficacy due to their low effectiveness and adverse effects, resulting in low survival rates for patients with advanced and metastatic BCa. Therefore, the treatment of BCa still faces great challenges, and there is an urgent need to discover an effective new antitumor drug. With the improvement of medical standards, traditional Chinese medicine has shown great advantages in the treatment of BCa. Traditional Chinese medicine is mild and easy to accept, and can inhibit tumor progression through a multi-pathway, multi-way and multi-target manner, so as to exert its anticancer effect. Taraxaci Herba is a medicinal and food homologous plant, which has many biological activities, such as antibacterial, anti-inflammatory, anti-oxidation, anti-tumor, protecting liver and gallbladder, reducing blood sugar and enhancing immunity, and it has shown a clear anticancer effect in breast cancer, liver cancer, gastric cancer, tongue cancer and lung cancer. By reviewing previous studies worldwide, this article summarizes the mechanism of Taraxaci Herba extract in inducing autophagy and apoptosis, inhibiting cell migration and invasion, regulating cell cycle and proliferation, regulating cell metabolism, inhibiting tumor angiogenesis, combining the effects of chemotherapeutic drugs, and regulating the transduction of related signal pathways. On this basis, this study systematically elaborates on the potential mechanism of Taraxaci Herba against BCa, in order to provide a theoretical basis for the research and treatment of BCa.

RESUMO

OBJECTIVE To study the antifungal activity of Huangqin decoction (HQD) against Trichophyton mentagrophytes and explore its mechanism. METHODS Minimal inhibitory concentration (MIC), minimal fungicidal concentration (MFC), mycelial length, spore germination rate, biomass and mycelium ultrastructure observation were performed to evaluate the antifungal activity of HQD against T. mentagrophytes. The effects of HQD on the cell wall of T. mentagrophytes were detected through sorbitol protection experiment. By measuring the content of ergosterol and the activities of squalene epoxide (SE) and lanosterol 14α-demethylase (CYP51), the activity of HQD on the cell membrane of T. mentagrophytes was investigated. The effects of HQD on T. mentagrophytes mitochondria were investigated by determining the activities of malate dehydrogenase (MDH), succinate dehydrogenase (SDH), and ATPases (including sodium potassium ATPase, calcium magnesium ATPase, and total ATPase). RESULTS HQD exhibited significant antifungal activity against T. mentagrophytes with MIC of 3.13 mg/mL and MFC of 25 mg/mL. After intervention with HQD, the mycelial length of T. mentagrophytes was significantly shortened (P<0.05); spore germination rate, biomass, the content of ergosterol in the cell membrane, the activities of SE and CYP51 in the cell membrane and MDH, SDH and ATPase in mitochondria were all decreased significantly (P<0.05); cell structure had been ;damaged to a certain extent, but the integrity of the cell wall had not been affected. CONCLUSIONS HQD shows significant antifungal activity against T. mentagrophytes, the mechanism of which may be associated with reducing the 0791- content of ergosterol in the cell membrane and the activities of SE, CYP51, and mitochondria-related enzymes.

RESUMO

Gancao Fuzitang originates from the Treatise on Febrile Diseases and Miscellaneous Diseases (《伤寒杂病论》) and is mainly used to treat pain in the bones and joints and symptoms such as no flexion or extension. It has the effect of tonifying the spleen and kidney and removing dampness and turbidity, so it is widely used in the clinical treatment of various bone and joint diseases. This article reviewed the clinical research and mechanism of Gancao Fuzitang in the treatment of bone and joint diseases. The research has found that this prescription has good efficacy in treating bone and joint diseases such as rheumatoid arthritis, rheumatoid arthritis, ankylosing spondylitis, gout, and intervertebral disc herniation. Its mechanism of action may be related to regulating the level of inflammatory factors, antioxidation, and the protein expression of inflammatory and apoptotic cell-related pathways, improving bone and joint diseases, and alleviating related symptoms. This study can provide a reference for further deepening the research on the prevention and treatment of bone and joint diseases with Gancao Fuzitang.

RESUMO

Ulcerative colitis (UC) is a chronic inflammatory bowel disease with complex etiology. The pathogenesis of this disease, due to a combination of factors, is complex and has not yet been elucidated. Among them, intestinal mucosal barrier damage is the basic pathological change of UC. As a non-destructive response of cells, autophagy regulates intestinal mucosal immunity, inflammation, oxidative stress, and bacterial homeostasis through degradation and reabsorption to actively repair damaged intestinal mucosal barrier, exerting a key role in the occurrence and development of UC. The disease is mainly treated clinically with aminosalicylic acid preparations, glucocorticoids, and immunosuppressants. Western medicine treatment of the disease has a fast onset of effect, and the short-term efficacy is definite, but the long-term application is easy to be accompanied by more adverse reactions. Moreover, some drugs are expensive, bringing great physical and mental pain and economic burden to patients. Therefore, it is urgent to explore new therapies with stable efficacy and mild adverse effects. In recent years, a large number of studies have shown that Chinese medicine can regulate autophagy of the intestinal mucosa with multiple targets and effects and repair the intestinal mucosal barrier function, thereby inhibiting the development of UC. Many experiments have shown that the active ingredient or monomers and compound formulas of Chinese medicine can improve the immunity of the intestinal mucosa, inflammation, oxidative stress, and flora by regulating the level of autophagy to maintain the normal function of the intestinal mucosal barrier to effectively intervene in UC, providing a new measure for the prevention and treatment of UC. However, there is a lack of systematic review of Chinese medicine in regulating the level of autophagy in the intestinal mucosa for the prevention and treatment of UC. Therefore, based on the current research on UC, autophagy process, and Chinese medicine treatment, this article reviewed the relationship of autophagy and its key target proteins with UC to clarify the key role of autophagy in UC production and systematically summarized Chinese medicines targeting the regulation of autophagy to treat UC in recent years to provide new ideas for the treatment and drug development of UC.
