Exploring the Pathogenesis of T2DM based on the Correlation between “Qi-fire Imbalance” and Ferroptosis / 中医杂志

@#Ferroptosis is a novel iron-dependent mode of programmed cell death characterized by iron deposition and accumulation of lipid peroxidation. More and more studies have found that ferroptosis is closely related to the pathogenesis of type 2 diabetes mellitus （T2DM）. The yin-fire theory is an important part of LI Gao's spleen-stomach theory， and it is believed that qi-fire imblance and yin-fire internal generation is the main pathogenesis of T2DM. Abnormal iron metabolism may be an important prerequisite for T2DM yin-fire internal generation， while oxidative stress is the specific manifestation of T2DM qi-fire imbalance. Reactive oxygen species （ROS） is the end product of qi-fire imbalance， and lipid peroxide is the pathological products of T2DM yin-fire internal generation. This study intends to explore the pathological mechanism of qi-fire imbalance and yin-fire internal generation from the perspectives of iron metabolism， oxidative stress and lipid peroxidation， enriching the modern connotation of yin-fire theory， and benefiting traditional Chinese medicine to target against ferroptosis， and prevent and treat T2DM precisely.

Treatment of Chronic Cough of Phlegm-Dampness Syndrome Based on the Theory of “Removing the Earth Stagnation” / 中医杂志

This paper discussed the treatment of chronic cough of phlegm-dampness type based on the theory of “removing the earth stagnation”. It is believed that stagnation of qi in the middle energizer caused malfunction of water metabolism in the human body， which is the key pathogenetic mechanism leading to phlegm-dampness cough. Pathogenesis like cold and dampness attacking the spleen， dampness-heat obstruction， weakness of the middle energizer， failure to ascend clear yang， and internal blazing of yin fire may lead to “earth stagnation”， which triggered phlegm-dampness cough. The treatment advocated “removing the stagnation” to improve qi transformation in the middle energizer， eliminate stagnation， and use different treatment methods such as warming the middle， circulating qi， transforming phlegm and dampness based on different disease cause and mechanism to calm cough. As for prescriptions， Jiangling Banxia Decoction （姜苓半夏汤） could be used for cold-dampness syndrome， Banxia Xiexin Decoction （半夏泻心汤） plus Xiangsu Powder （香苏散） used for damp-heat syndrome， and Buzhong Yiqi Decoction （补中益气汤）， Tiaozhong Yiqi Decoction （调中益气汤）， Shengyang Yiwei Decoction （升阳益胃汤） and Bupiwei Xieyinhuo Shengyang Decoction （补脾胃泻阴火升阳汤） could be selected for spleen-stomach weakness syndrome according to different characteristics and pathogenesis.

Relationship Between Metabolic Remodeling of Endothelial Cells and Tumor Angiogenesis Based on "Yin Fire" Theory and Intervention of Chinese Medicine / 中国实验方剂学杂志

Endothelial cells in the inner wall of blood vessels respond to physical and chemical signals of the body by regulating vascular homeostasis， vascular tension， cell adhesion， cell proliferation， coagulation resistance and inflammatory factors， to maintain the stability of blood vessels. Angiogenesis is the key condition for tumor evolution， and the pathological mode of tumor angiogenesis provides nutrients and oxygen for tumor growth and promotes its proliferation. In recent years， endothelial cells have participated in tumor vascular infiltration and driven angiogenesis， which is considered to be the point link in tumor metastasis. By regulating metabolic remodeling， vascular endothelial cells provide the materials and energy needed in the process of tumor angiogenesis， and their abnormal metabolic characteristics facilitate their adaption to the changes of tumor microenvironment， which is often regarded as an important basis for tumor angiogenesis. The ''Yin fire'' theory in traditional Chinese medicine， originating from Huangdi's Internal Classic （Huang Di Nei Jing）， originally meant Yin deficiency generates internal heat， and belonged to the category of fire of internal injury. After the deduction and changes by physicians over the ages， the pathogenesis of ''spleen and stomach Qi deficiency-Yin fire rising-Qi and fire disharmony'' was gradually formed. The pathogenesis of metabolic remodeling of endothelial cells manifests the pathological characterization of Yin fire in an objective way， which is consistent with the disease state of uncontrolled and hyperactive tumor neovascularization. Changes in spleen and stomach Qi deficiency as well as imbalance of Qi movement lead to the failure of water and food in distribution， and thus metabolic disorders occur. Long term retention turns in phlegm and blood stasis， which combat with blood vessels， and result in abnormal local environment （formation of tumor microenvironment）， adverse pulse channel （imbalance of endothelial cell metabolism）， and tumor neovascularization. Under the guidance of ''Yin fire'' syndrome elements and by focusing on the correlation between Qi and fire， prescriptions are made based on the treatment method of ''strengthening the body and regulating Qi'' to regulate the metabolic function of endothelial cells， thus achieving a relatively balanced state of the body and inhibiting tumor angiogenesis. As a result， this study， centering on the metabolic remodeling of endothelial cells and ''Yin fire'' theory， elucidated the academic ideas， with the purpose of providing some theoretical support for the intervention of tumor vascularization by Chinese medicine.

Discussion on the Formation and Prevention Strategies of Chemotherapy Resistance of Malignant Tumor Based on “Yin Fire” Theory / 中医杂志

Chemotherapy is currently the main clinical treatment method for malignant tumors， and chemotherapy resistance is the main factor leading to chemotherapy failure and malignant tumor recurrence and metastasis. The cha-racteristics of malignant tumors formation were regarded as similar to the “Yin Fire” theory， manifested that deficiency of original qi as the foundation of malignant tumors， imbalance of original qi and yin fire as the internal cause of malignant tumor progression， and the internal environment of phlegm-blood stasis-toxicity-deficiency caused by yin fire promoted the formation of chemoresistance. In the treatment of chemoresistance of malignant tumors， traditional Chinese medicine should focus on treating disease before its onset by tonifying the spleen and strengthening the middle， nou-rishing the original qi， and reinforcing healthy qi and anti-cancer； during the treatment， the clinicians should regulate the qi and detoxify to clear yin fire， and improve the internal environment. Summarily， the strategies were adjusting the balance of internal environment of original qi and yin fire， and conducting a comprehensive treatment during the whole process， to provide new ideas for the treatment of chemoresistance of malignant tumors with traditional Chinese medicine.
