This paper aimed to investigate the therapeutic effect and mechanism of action of the Yiqi Fumai Formula(YQFM), a kind of traditional Chinese medicine(TCM), on mice with experimental heart failure based on the "heart-gut axis" theory. Based on the network pharmacology integrated with the group collaboration algorithm, the active ingredients were screened, a "component-target-disease" network was constructed, and the potential pathways regulated by the formula were predicted and analyzed. Next, the model of experimental heart failure was established by intraperitoneal injection of adriamycin at a single high dose(15 mg·kg~(-1)) in BALB/c mice. After intraperitoneal injection of YQFM(lyophilized) at 7.90, 15.80, and 31.55 mg·d~(-1) for 7 d, the protective effects of the formula on cardiac function were evaluated using indicators such as ultrasonic electrocardiography and myocardial injury markers. Combined with inflammatory factors in the cardiac and colorectal tissue, as well as targeted assays, the relevant indicators of potential pathways were verified. Meanwhile, 16S rDNA sequencing was performed on mouse fecal samples using the Illumina platform to detect changes in gut flora and analyze differential metabolic pathways. The results show that the administration of injectable YQFM(lyophilized) for 7 d significantly increased the left ventricular end-systolic internal diameter, fractional shortening, and ejection fraction of cardiac tissue of mice with experimental heart failure(P<0.05). Moreover, markers of myocardial injury were significantly decreased(P<0.05), indicating improved cardiac function, along with significantly suppressed inflammatory responses in cardiac and intestinal tissue(P<0.05). Additionally, the species of causative organisms was decreased, and the homeostasis of gut flora was improved, involving a modulatory effect on PI3K-Akt signaling pathway-related inflammation in cardiac and colorectal tissue. In conclusion, YQFM can affect the "heart-gut axis" immunity through the homeostasis of the gut flora, thereby exerting a therapeutic effect on heart failure. This finding provides a reference for the combination of TCM and western medicine to prevent and treat heart failure based on the "heart-gut axis" theory.

Objective : To investigate the effect and mechanism of M2 macrophage polarization induced by HCT116 with highly metastatic colorectal cancer cells on immune escape in colorectal cancer. Methods : After the co-culture of colorectal cancer cells conditioned medium(CM) and PMA-induced M0 macrophages, the polarization of M2 macrophages was observed by flow cytometry, real-time polymerase chain reaction(qPCR) and enzyme-linked immunosorbent assay(ELISA) experiments. The CMM0, CMSW480-Mφ and CMHCT116-Mφ were co-cultured with HCT116 cells, and the expression of programmed death-ligand 1(PD-L1) was detected by Western blot and qPCR. At the same time, the stimulated HCT116 cells were co-cultured with human T lymphocytes to detect the survival of HCT116 cells and the levels of tumor necrosis factor-α(TNF-α) and interferon-γ(IFN-γ). The difference of kruüppel-like factor 4(KLF4) expression between SW480 and HCT116 cells was detected by Western blots, qPCR and ELISA. After pretreatment of HCT116 cells with KFL4 inhibitor Kenpaullone(Ken), the CMHCT116 and CMHCT116+Ken were co-cultured with M0 macrophages and the polarization of M2 macrophages was observed by flow cytometry, qPCR and ELISA. The CMHCT116-Mφ and CM_((HCT116+Ken)-Mφ) was co-cultured with HCT116 cells, and the PD-L1 expression of HCT116 cells was detected by Western blot and qPCR. Results: After the stimulation of M0 macrophages with CM, the proportion of CD11b+CD206+ cells in HCT116-Mφ cells was higher, and the expression of M2 macrophage markers interleukin(IL-10) and transforming growth factor-β(TGF-β) were higher. Compared with the CMSW480-Mφ group, the PD-L1 protein expression level was higher in the CMHCT116-Mφ group. After co-culture with T lymphocytes, the cell survival rate are the most in CMHCT116-Mφ group, while the levels of TNF-α and IFN-γ were the lowest. After the addition of Ken, the polarization ratio and markers of M2 macrophages decreased. Compared with CMHCT116-Mφ group, the expression of PD-L1 in HCT116 cells of the CM_((HCT116+Ken)-Mφ) group decreased. Conclusion Highly metastatic colorectal cancer cells induce polarization of M2 macrophages by secreting KLF4, promote PD-L1 expression in colorectal cancer cells, facilitate tumor immune escape, and provide potential targets for clinical immunotherapy.

The population aging and the coming of the information era are accompanied with the growing incidence of spinal degenerative diseases, which result in heavy social and economic burdens. Under the guidance of the tendon-bone theory, rich experience has been accumulated in the prevention and diagnosis of spinal degenerative diseases with traditional Chinese medicine(TCM), which demonstrates unique advantages. China's government has placed people's health in the strategic position of development, providing a favorable environment for the realization of healthy aging. The Healthy China 2030 advocates special actions for healthy bones. As China is facing an important period of demographic transition, the Traditional Chinese Medicine for Bone Health Program has emerged, combining the needs of the national health strategy and the advantages of TCM. This paper discusses the background and significance of the program. According to the theory of five body constituents and the characteristics of musculoskeletal system diseases, this paper constructs a theoretical system of "tendon-meridian-muscle-bone-marrow" to explain the structure and function of the musculoskeletal system. From the holistic view of TCM, this system shows not only the structure and function of the musculoskeletal system but also the patterns of disease development and the mechanism of TCM treatment. The system facilitates the research on not only the comorbidities related to bone health but also the occurrence, development, and outcome of diseases. In the management of chronic degenerative diseases, attention should be paid to the establishment and improvement of the disease prevention and control system in addition to the disease treatment alone. Finally, this paper introduces the characteristic advantages of TCM in the whole process of prevention, diagnosis, treatment, rehabilitation, and health maintenance of spinal degenerative diseases, aiming to enrich the connotation of the tendon-bone theory, provide ideas and implementation strategies for TCM clinical practice, and ultimately achieve the effective management of the diagnosis and treatment of spinal degenerative diseases.
