Chronic obstructive pulmonary disease (COPD), as a chronic respiratory disease that can be prevented and intervened but cannot be completely cured, has increasing incidence and mortality rates year by year, often complicated by one or more comorbidities. However, there is currently no specific treatment available. Therefore, the healthcare issues related to COPD are urgent and prominent. Traditional Chinese medicine (TCM) delays the progression of COPD through multiple mechanisms, pathways, and targets. As a result, exploring the pathogenesis of COPD and identifying TCM treatment approaches and effective prescriptions are key issues that urgently need to be addressed in clinical practice. In TCM, COPD is categorized into syndromes such as "cough", "asthma", and "lung distension". It is believed that the deficiency in the origin runs through the entire disease. When external pathogens invade, Qi becomes disordered, and phlegm and blood stasis begin to accumulate, leading to an excess condition in the manifestation. Modern medicine research on the pathogenesis of COPD mainly involves aspects such as inflammatory response, oxidative stress, autophagy imbalance, and aging. Studies have found that Chinese medicine monomers, single herbs, and compound prescriptions can improve COPD by inhibiting inflammation, reducing oxidative damage, correcting autophagy, and delaying aging. However, there is no study that intuitively organizes the various pathogenesis mechanisms of COPD and their interrelationships. At the same time, research on the therapeutic effects of TCM on COPD primarily focuses on exploring a single mechanism or pathway, without integrating multiple mechanisms, pathways, and targets. Additionally, there are very few studies that summarize the corresponding relationships between the various pathogenesis mechanisms of COPD and the regulatory effects and signaling pathways of Chinese medicine. This study, for the first time, combines the latest literature in China and abroad to explain the various pathogenesis mechanisms of COPD and their interrelationships using a combination of graphs, text, and tables. It also outlines the signaling pathways, targets, and mechanisms of Chinese medicine monomers, single herbs, and compound prescriptions in regulating COPD, in order to provide new ideas and strategies for the in-depth research and systematic treatment of COPD with TCM.

ObjectiveTo evaluate the efficacy of Shexiang Baoxinwan in treating stable angina pectoris with Qi stagnation and blood stasis syndrome in patients with coronary artery disease (CAD) complicated with anxiety and depression and explore its underlying mechanisms. MethodsThis study employed a randomized, double-blind, and placebo-controlled clinical trial design. Patients admitted to the hospital were randomly assigned to the observation group and the control group, with 52 patients in each group. Patients in the observation and control groups received Shexiang Baoxinwan and placebo, respectively, both in combination with conventional Western medication. The dose was 45.0 mg, three times daily, for a total duration of eight weeks. The primary outcome was the Seattle Angina Questionnaire (SAQ) scores before and after treatment. Secondary outcomes included changes in traditional Chinese medicine (TCM) syndrome score, the patient health questionnaire-9 (PHQ-9), generalized anxiety disorder-7 (GAD-7), inflammatory markers [interleukin-18 (IL-18), interleukin-10 (IL-10), tumor necrosis factor-alpha (TNF-α), CD40, etc.], monoamine neurotransmitters [e.g., dopamine (DA)], vascular endothelial function markers [e.g., endothelin-1(ET-1)], adipokines, and ischemia-modified albumin (IMA). Adverse reactions were also recorded. ResultsA total of 92 patients completed the study, with 44 in the observation group and 48 in the control group. Compared with baseline, both groups showed significant decreases in PHQ-9, GAD-7, and TCM syndrome scores following treatment (P<0.05), along with a significant increase in SAQ scores (P<0.05). In the observation group, DA levels were significantly increased (P<0.05), while levels of IL-18, TNF-α, CD40, ET-1, and IMA were decreased (P<0.05). In contrast, the control group exhibited significantly increased CD40 levels (P<0.05). Compared with the control group after treatment, the observation group showed significant improvements in the SAQ dimensions of physical limitation, angina stability, treatment satisfaction, and disease perception, as well as in TCM syndrome score, PHQ-9 score, IL-18, CD40, ET-1, and IMA (P<0.05). No adverse reactions were observed in either group during treatment. ConclusionShexiang Baoxinwan can improve anxiety and depression, alleviate angina symptoms, and reduce TCM symptoms of Qi stagnation and blood stasis in CAD patients. The mechanism may involve anti-inflammation, improvement of vascular endothelial function, reduction of IMA, and increase of monoamine neurotransmitter levels.

ObjectiveTo investigate the intervention effect of Jiedu Tongluo Tiaogan prescription (JTTP) in protecting pancreatic β cells by targeting the bile acid Takeda G protein-coupled receptor 5 (TGR5)/cyclic adenosine monophosphate (cAMP) signaling pathway against NOD-like receptor protein 3 (NLRP3) inflammasome. MethodThirty-two male SPF-grade db/db mice were randomly divided into the model group, low-dose JTTP group (3.6 g·kg-1), high-dose JTTP group (7.2 g·kg-1), and metformin group (0.2 g·kg-1). Eight db/m mice were assigned to the blank control group. The mice were treated with drugs for 8 weeks, and fasting blood glucose (FBG) was measured every 2 weeks. Oral glucose tolerance tests (OGTT) were conducted after the last administration. Enzyme-linked immunosorbent assay (ELISA) was performed to detect fasting insulin (FINS), and the homeostasis model assessment of β-cell function (HOMA-β), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), and IL-1β levels were calculated. Hematoxylin-eosin (HE) staining was used to observe pathological changes in mouse pancreatic tissue. Immunofluorescence was performed to detect insulin expression in mouse pancreatic tissue. Western blot and real-time quantitative polymerase chain reaction (Real-time PCR) were used to detect the expression of proteins and mRNAs of key targets in the TGR5/cAMP signaling pathway and NLRP3 inflammasome. ResultCompared with blank group, FBG, OGTT, FINS, IL-6, TNF-α and IL-1β in model group were significantly increased (P<0.01). Compared with model group, after 6 weeks of drug treatment, FBG level in JTTP group and metformin group decreased significantly (P<0.01). The results of OGTT experiment showed that compared with model group, the blood glucose levels of mice in each administration group were decreased at all time points (P<0.05, P<0.01), and the levels of FINS, TNF-α and IL-6 in JTTP dose groups and metformin group were significantly decreased. The level of IL-1β in JTTP high-dose group and metformin group was significantly decreased (P<0.01). Pancreatic pathology showed that the islets in the model group were irregular in shape, uneven in distribution, and showed signs of atrophy. The prognosis of JTTP was that the cell count increased and the boundary was clearer. Immunofluorescence results showed that the islet cells in the blank group were arranged in an orderly and full shape with appropriate insulin secretion, while the islet cells in model group were distorted in shape, atrophy in structure and less insulin secretion. The insulin content of mice in JTTP and metformin group was significantly increased. Compared with blank group, mRNA expressions of NLRP3, apoptosis-related spot-like protein (ASC) and Caspase-1 in pancreatic tissues of model group were significantly increased (P<0.01). Compared with model group, JTTP high-dose group and metformin group promoted the up-regulation of TGR5 and cAMP mRNA, and down-regulated the mRNA expressions of NLRP3, ASC and Caspase-1 (P<0.05, P<0.01). Compared with blank group, the expression of TGR5 protein in model group was significantly decreased (P<0.01). Compared with model group, TGR5 protein in JTTP high-dose group and metformin group was significantly increased (P<0.01).

The complex chemical composition and limited research ideas of traditional Chinese medicine (TCM) have led to the unclear material basis and mechanism of the medicinal effects, which is a common problem hindering the modernization of TCM in China. The introduction of computer virtual technology has provided a new perspective for TCM research. In this study, we established the research method of structure-activity omics to study the relationships between the structures and effects of different compounds in TCM based on the chemical structures of TCM components and to analyze and predict the material basis and multitarget synergistic mechanism of TCM. Furthermore, a structure-activity omics study was carried out with the anti-inflammatory and analgesic effects of Qizhi Weitong granules as an example. This study provides support for screening the pharmacodynamic components and analyzing the active ingredients of TCM and gives insights into the research on the material basis and mechanism of compound efficacy and the development of lead compounds of TCM, thus promoting the modern research and the innovative development of TCM.

ObjectiveTo explain the anti-inflammatory and analgesic effects of Corydalis Rhizoma by the means of structure-activity omics. MethodOn the basis of the previous in vitro screening study, we studied the in vivo efficacy of the alkaloids in Corydalis Rhizoma. With the targets as a bridge, the structures of chemical components in Corydalis Rhizoma were connected with the efficacy. The molecular docking of the alkaloids in Corydalis Rhizoma with the targets of inflammation and pain was carried out. According to the docking scores and the differences in the structural nucleus of Corydalis Rhizoma alkaloids, a study of structure-activity omics was carried out to summarize the rules of their connection. ResultThe alkaloids in Corydalis Rhizoma had good anti-inflammatory and analgesic effects in vivo, involving 53 chemical components and 73 targets. There were 3 074 targets associated with inflammation and pain, and 42 targets of direct action were shared by the chemical components and the disease. The protein-protein interaction (PPI) and molecular docking analysis predicted that the main active components of Corydalis Rhizoma were tetrahydropalmatine and palmatine, and the core targets were prostaglandin endoperoxide synthase 2 (PTGS2), glutamate receptor metabotropic 5 (GRM5), estrogen receptor 1 (ESR1), solute carrier family 6 member 4 (SLC6A4), and fusion oncoproteins (FOS). According to the differences of mother nucleus, the 53 alkaloid components of Corydalis Rhizoma were classified into 8 categories, including protoberberine, berberine, and aporphine, which had high binding affinities with PTGS2, GRM5 and other targets. The relationship between the structures of Corydalis Rhizoma alkaloids and docking scores in each group showed the same law. In protoberberine, appropriate substituents with hydroxyl, alkoxy or methyl groups on the A and D rings of the parent ring were conducive to enhancing the binding activities with the two targets. In berberine, the structure containing a methyl group on position 13 had strong binding affinities with the two targets. It is hypothesized that the methyl fragment changes the binding mode between the component structure and amino acid residues, which greatly improves the binding affinity. ConclusionThis study employs the method of structure-activity omics to analyze the material basis for the anti-inflammatory and analgesic effects of alkaloids in Corydalis Rhizoma, and the structure-activity omics provides new ideas for revealing the pharmacodynamic substances of traditional Chinese medicine.
