Multiple sclerosis(MS) shows the pathological characteristics of "inflammatory injury of white matter" and "myelin repair disability" in the central nervous system(CNS). It is very essential for MS treatment and reduction of disease burden to strengthen repair, improve function, and reduce disability. Accordingly, different from the simple immunosuppression, we believe that key to strengthening remyelination and maintaining the "damage-repair" homeostasis of tissue is to change the current one-way immunosuppression strategy and achieve the "moderate pro-inflammation-effective inflammation removal" homeostasis. Traditional Chinese medicine shows huge potential in this strategy. Through literature research, this study summarized the research on remyelination, discussed the "mode-rate pro-inflammation-effective inflammation removal" homeostasis and the "damage-repair" homeostasis based on microglia, and summed up the key links in remyelination in MS. This review is expected to lay a theoretical basis for improving the function of MS patients and guide the application of traditional Chinese medicine.

The iron and inflammation homeostasis are closely coupled, forming an integrated functional unit under physiological conditions. "Iron transport balance" has become the key mechanism to maintain iron homeostasis through bidirectional regulation of iron uptake and release and dynamic management of transmembrane concentration. It is also the physiological basis for the inflammatory balance between promotion and resolution. Under pathological conditions, represented by inflammatory bowel disease (IBD), disturbed iron transportation was highly involved in almost every step of inflammatory diseases. Therefore, the iron transporting rebalancing provides the mechanistic basis and effective approach for the normalization of inflammatory microenvironment. Macrophage is the key regulator of inflammation homeostasis and determinant for iron transport balance. Unfortunately, the current clinical transformation based on iron transport balance theory has still been insufficient. Sometimes, this strategy even showed high complexity and contradiction, severely restricting its clinical application. By summarizing the theoretical research progress of iron transport balance, especially its relevance to macrophage phenotypic polarization, this review aims to explore the therapeutic value in inflammation intervention by targeting iron transporting balance. This review will provide the necessary knowledge and hints for the research and development of candidate drugs in treating inflammatory diseases.

Respiratory infectious diseases are important diseases causing major public safety events, posing a great threat to life, health, and social development. Effective control and scientific treatment of the diseases is the key basis for ensuring the stability and long-term development of the community of a shared future for human health. Although the pathogens of respiratory viral infectious diseases are diverse and the process is complex, the common pathological basis of their pathogenesis is characterized by the "damage-repair" functional imbalance of the immune microenvironment of the lesions, which leads to the subsequent structural and functional destruction of important organs. Therefore, the treatment should focus on antivirus and immunological regulation, strengthen the protection against immune injury, and promote the functional repair of damaged tissues. The above conclusions are the scientific core of host-directed therapies(HDT), which coincides with "human-disease co-treatment and healthy qi and pathogen interaction" in traditional Chinese medicine(TCM) theories. Under the support of TCM and western medicine theories, the complete pathological chain "infection-immunity-injury" of respiratory viral infectious diseases is integrated with dynamic change in "healthy qi-pathogen" in TCM to transform the treatment focus from the diseases to the patients. It is possible to fundamentally correct the "damage-repair" imbalance in the disease state, change the environment for disease development, and bring benefits to patients by strengthening human intervention, maintaining immune homeostasis, enhancing the protection of tissues and organs, and promoting the repair and regeneration of damaged tissues. This study focused on the common and key pathological processes of respiratory infectious diseases, especially the immune damage caused by the viral infection, to seek effective prevention and treatment strategies, review relevant theoretical progress, summarize effective drug candidates, prospect future research and development, and highlight the therapeutic characteristics of TCM.

Complete healing of the intestinal mucosa is the most ideal goal in the treatment of inflammatory bowel disease (IBD). The intestinal mucosa healing not only significantly alters the course of the disease and relieves clinical symptoms, but also markedly reduces the occurrence of complications and prevents recurrence of IBD. As chronic inflammation associated with peptic ulcer damage is the main pathological feature of IBD, clinical treatment is mainly based on anti-inflammatory therapy, but such therapy cannot promote the healing of the intestinal mucosa of patients. Therefore, how to achieve long-term remission of IBD is still an urgent challenge. In the process of intestinal mucosal repair, the polarization of macrophages maintains the homeostasis of the intestinal microenvironment, which is a representative process that promotes mucosal inflammatory-repair. It is a key part of initiating tissue regeneration that should not be underestimated. In this paper, we reviewed the literature of the past decade, focusing on the promotion of intestinal mucosal healing in IBD. The discussion will highlight the importance and feasibility of regulating macrophages to promote intestinal mucosal repair. Following this thought, we discuss the shortcomings of current clinical treatments and summarize the relevant drugs which have potential to promote intestinal mucosal repair. The aim is to provide effective potential drugs and therapeutic targets for the treatment of IBD.
