RESUMEN

Diabetic cardiomyopathy(DCM) is a chronic complication of diabetes mellitus that leads to cardiac damage in the later stages of the disease, and its pathogenesis is complex, involving metabolic disorders brought about by a variety of aberrant alterations such as endoplasmic reticulum stress, oxidative stress, inflammation, and apoptosis, defects in cardiomyocyte Ca~(2+) transporter, and myocardial fibrosis. Currently, there is a lack of specific diagnosis and treatment in the clinic. Autophagy is a highly conserved scavenging mechanism that removes proteins, damaged organelles or foreign contaminants and converts them into energy and amino acids to maintain the stability of the intracellular environment. Inhibition of autophagy can cause harmful metabolites to accumulate in the cell, while over-activation of autophagy can disrupt normal cellular structures and cause cell death. Prolonged high glucose levels disrupt cardiomyocyte autophagy levels and exacerbate the development of DCM. The protective or detrimental effects of autophagy on cells ring true with the traditional Chinese medicine theory of healthy Qi and pathogenic Qi. Autophagy in the physiological state of the removal of intracellular substances and the generation of substances beneficial to the survival of cells is the inhibition of pathogenic Qi to help the performance of healthy Qi, so the organism is healthy. In the early stages of the disease, when autophagy is impaired and incapable of removing waste substances, pathogenic Qi is prevalent; In the later stages of the disease, excessive activation of autophagy can destroy normal cells, leading to a weakening of healthy Qi. Traditional Chinese medicine has the advantage of targeting multiple sites and pathways. Studies in recent years have confirmed that traditional Chinese medicine monomers or formulas can target autophagy, promote the restoration of autophagy levels, maintain mitochondrial and endoplasmic reticulum homeostasis, and reduce oxidative stress, endoplasmic reticulum stress, inflammation, and apoptosis in order to prevent and control DCM. This study provides a review of the relationship between autophagy and DCM and the intervention of traditional Chinese medicine in autophagy for the treatment of DCM, with a view to providing new clinical ideas and methods for the treatment of DCM with traditional Chinese medicine.

RESUMEN

Based on the duality of "healthy" and "pathogenic" of the immune system in physiological and pathological states， and combined with the analogy between "immune function" and "healthy qi"， the theory of "transformation of healthy qi into pathogenic qi" was proposed to guide the pattern identification and treatment of autoimmune diseases. The theory of "transformation of healthy qi into pathogenic qi" means that "healthy qi"， which is originally used by the body's original ability to defend and remove harmful factors or normal functional activities， transformed into "pathogenic qi"， which is factors that damage and destroy the human body or abnormal body state. In the pathogenesis of autoimmune diseases， the pathogenic factors and causes of congenital endowment， tissue damage under the influence of external pathogens， abnormal function of zang-fu （脏腑） organs and meridians， abnormal transmission and transformation of qi， blood， body fluids was proposed. Autoimmune diseases have the dynamic mechanism of latent pathogen at early stage， internal and external contraction at the onset stage， and the expansion of the pathogenic qi at the complete period， and also have the characteristics of the specificity， invisibility and contradiction of healthy qi and pathogenic qi. In terms of treatment， it advocates the ideas of treatment with both attack and supplementation throughout the disease， identifying diseases with special prescriptions and formulas for specific diseases， dynamically adjusting treatment by identifying the remission and onsets of the disease， observing the changes in the dynamics of healthy qi transforming into pathogenic qi， and treating disease before it arises with early intervention.

RESUMEN

Autophagy， a mechanism of cell self-protection and self-renewal， is associated with the occurrence and development of lung cancer. Favorable autophagy can slow down the progression of lung cancer， while unfavorable autophagy can promote the progression. Therefore， regulating the level of autophagy is of great significance in the treatment of lung cancer. Healthy Qi deficiency and pathogenic Qi stagnation is an extension of the theory of deficiency and Qi stagnation proposed by the Academician WANG Yongyan. It refers to the pathological process that the abnormal body fluid metabolism caused by Qi deficiency of lung， spleen， and kidney results in phlegm and blood stasis. Lung cancer has the root cause of Qi deficiency of lung， spleen， and kidney and the syndrome of phlegm and blood stasis. The autophagy in lung cancer is interconnected with healthy Qi deficiency and pathogenic Qi stagnation. The Qi deficiency of lung， spleen， and kidney is the key factor for the weakening of favorable autophagy in lung cancer， which inhibits the apoptosis of tumor cells and leads to the accumulation of harmful substances. Phlegm and blood stasis is a direct factor enhancing the unfavorable autophagy in lung cancer， which promotes the autophagic death of normal cells， weakens the immunosuppressive effect of immune cells on tumor cells， and leads to the proliferation and migration of tumor cells. The combination of healthy Qi deficiency and pathogenic Qi stagnation results in the development of autophagy in an unfavorable direction and finally leads to the continuous progression of lung cancer. Therefore， the traditional Chinese medicine （TCM） treatment of lung cancer should follow the principle of reinforcing healthy Qi and expelling pathogenic Qi， removing phlegm and resolving stasis， so as to enhance favorable autophagy while inhibiting unfavorable autophagy. Such therapy can inhibit the proliferation and migration of tumor cells and promote the remission of lung cancer. According to the existing literature， Chinese medicine monomers are mainly used to treat lung cancer by regulating autophagy. The Chinese medicine intervention of autophagy in lung cancer mainly aims to promote the activation of autophagy. This may be because the favorable autophagy weakening caused by the Qi deficiency of lung， spleen， and kidney is the fundamental reason for the development of lung cancer.

RESUMEN

This article highlighted the invaluable expertise of Academician TONG Xiaolin in managing severe cases of COVID-19， thereby providing ideas for the treatment of severe and critically ill patients with SARS-CoV-2 infection by integrating traditional Chinese and western medicine. It is believed that COVID-19 belongs to the “cold dampness epidemic” in traditional Chinese medicine， which is caused by pathogenic qi of cold and dampness. The course of the disease can be divided into four stages： constraint， block， collapse， and deficiency， and the severe cases are mainly in the block and collapse stages. The pathogenesis at the block stage is described as epidemic toxins blocking the lung， which should be treated by diffusing the lung and unblocking the bowels， resolving phlegm and unblocking collaterals. The primary formula used is Zilong Xuanbai Chengqi Decoction （子龙宣白承气汤） with modifications based on individual condition. The pathogenesis at the collapse stage is described as internal block and external collapse， which should be treated by restoring yang to save from collapse， boosting qi to relieve collapse， diffusing the lung and unblocking the bowels， resolving phlegm and unblocking collaterals， usually with the formula Poge Zilong Xuanbai Chengqi Decoction （破格子龙宣白承气汤） with modifications.

RESUMEN

Chronic heart failure is a serious heart disease with dyspnea and limited activity tolerance as the main clinical manifestations. Autophagy is a self-protection mechanism in eukaryotic cells and plays an important role in the development of heart failure. Appropriately increasing the level of autophagy during the compensated stage of heart failure and timely removal of necrotic myocardial organelles and other harmful garbage can inhibit myocardial hypertrophy to a certain extent，alleviate myocardial remodeling，and delay heart failure. The theory of healthy Qi and pathogenic Qi is an important basic theory for explaining the occurrence of diseases，and struggle between healthy Qi and pathogenic Qi exists in the entire onset of chronic heart failure，which may lead to pathogenic Qi invasion and healthy Qi deficiency. The regulatory effect of autophagy on cardiomyocytes is similar to the theory of healthy Qi and pathogenic Qi in traditional Chinese medicine （TCM）. Autophagy is the body's self-regulatory mechanism for healthy Qi and pathogenic Qi in a dose-effect manner，Specifically，autophagy can only protect the body's cells to a certain extent，and healthy Qi can only take effect within a certain range and degree. To protect the body from external pathogenic factors，excessive or insufficient autophagy may destroy the stability of the body's environment. In this regard，we use the theory of healthy Qi and pathogenic Qi as a starting point to clarify the function of autophagy in the development of chronic heart failure from a macro and micro perspective，and propose adjusting the balance of healthy Qi and pathogenic Qi in the body to regulate the autophagy of cardiomyocytes. The principle of prevention and treatment is expected to lay the foundation for modern research on the function of autophagy in the development of chronic heart failure in TCM，find novel therapy for chronic heart failure at different stages，and provide new insights into the diagnosis and treatment of chronic heart failure.

RESUMEN

With the emerging cases of tumor is about to exceed 4 million per year in China， tumor prevention and control is also a formidable barrier hitting the world. Overall， an increasing trend of incidence and mortality of tumor in China has been observed in recent years， and the high mortality and low cure rate of tumor have seriously threaten the health of Chinese people， greatly affected the quality of life of patients， greatly reduced the living standard of patients and endangered the physical and mental health of patients. Traditional Chinese medicine（TCM） believes that the etiology of tumor is complex and pathogenesis is variable， which is the result of interaction between internal and external factors. If the treatment is carried out based on syndrome differentiation in time at the beginning when exogenous pathogens act on the human body， so as to prevent the spread of latent pathogen in human body， the occurrence and development of tumor diseases will be significantly reduced. Therefore， the theory of exogenous pathogenic factors and the pathogenesis of tumor need to be further explored. A total of 67 Chinese and English literatures were searched out with key words like external contraction， pathogenic Qi， TCM， tumor and pathogenesis in China National Knowledge Infrastructure （CNKI） and Public Medline （PubMed） databases for reference， so as to discuss the theory of exogenous pathogens and the pathogenesis of tumor comprehensively. The important role of exogenous pathogens in tumor pathogenesis and the significance of TCM in the early prevention and treatment of tumors were emphasized. Exogenous pathogenic factors such as wind， cold， dampness， fire， natural and social factors， diet and living conditions lead to the complexity of the occurrence of tumors. TCM can effectively prevent and intervene in the early stage of tumor onset， contribute to disease prevention and tumor resistance， reduce the occurrence， development and transformation of tumors， and make the clinical medication more effective， more accurate and more targeted， so as not to miss the opportunity for treating tumor， and provide a more clear guidance for clinical treatment of tumors.

RESUMEN

OBJECTIVE: To observe the effect difference between blood-letting and cupping therapy combined with basic treatment and simple basic treatment for upper limb spasticity in the recovery phase of stroke. METHODS: Sixty patients of upper limb spasticity in the recovery phase of stroke were randomly assigned into an observation group and a control group, 30 cases in each group. In the control group, the basic treatment, including the internal treatment, acupuncture and rehabilitation, was used for 2 weeks, 6 times a week, once a day. Based on the basic treatment, blood-letting, at 3 jing-well points each time, and cupping therapy were used at the most obvious spasm point in the belly of biceps muscle in the observation group for 2 weeks, 3 time a week, once every other day. The spasm score, passive traction value, and moter function score of upper limb were assessed in the two groups before and after treatment. The effects were compared between the two groups. RESULTS: After treatment, the spasm scores and passive traction values were lower than those before treatment in the two groups (all P<0.01), with better score and value as well as different values before and after treatment in the observation group (P<0.05, P<0.01). After treatment, the motor function scores were higher than those before treatment in the two groups (both P<0.01), with better score and different value before and after treatment in the observation group (both P<0.05). The total effective rate was 90.0% (27/30) in the observation group, which was better than 76.7% (23/30) in the control group (P<0.05). CONCLUSION: Based on the basic treatment, blood-letting combined with cupping therapy are effective for upper limb spasticity in the recovery phase of stroke.
