Role of lymphatic system in coronary heart disease based on theory of combined phlegm and stasis / 中国中药杂志

According to the traditional Chinese medicine(TCM) theory, coronary heart disease(CHD) is mainly caused by heart vessel obstruction due to Qi stagnation, blood stasis, and phlegm turbidity. Chest impediment with combined phlegm and stasis is a common syndrome of CHD, with the manifestations of chest tightness, chest pain, and asthma. Lymphatic system is one of the important immune systems in the human body and has a close relationship with the Qi and blood movement in TCM. The dysfunction of the lymphatic system may lead to metabolism disorders, the generation of dampness pathogen which turns into sticky and difficult-to-dissolve phlegm turbidity. Moreover, it can affect blood circulation and coagulation, causing slow blood flow, increased blood viscosity, and microcirculation disorders. Alterations in lymphatic hydrodynamics may affect the interaction between blood circulation and the lymphatic system. A variety of small molecule drugs and TCM can treat cardiovascular diseases by targeting the lymphatic system. This review discusses the role of the lymphatic system in CHD based on the theory of combined phlegm and stasis, involving the influences of mechanical factors on lymphatic function and the effects and pharmacological mechanisms of TCM and chemicals that target lymphocyte function and lymphatic circulation. By expounding the development process of combined phlegm and stasis in CHD from the lymphatic system, this paper aims to provide new ideas for deciphering pharmacological mechanisms of TCM for resolving phlegm and stasis.

Treatment of Myocardial Injury from Coronavirus Disease-2019 by Chinese Medicine / 中国实验方剂学杂志

Myocardial injury from coronavirus disease-2019 (COVID-19) is a clinical sign after the novel coronavirus infection, which can be seen in common type and severe type in acute stage, or after recovery of COVID-19. From the mouth and nose, the epidemic and pathogenic factors enter the lung, involving the heart, so that Qi and blood are blocked and developed into myocardial injury. More than 100 patients with COVID-19 and rehabilitation were treated, and we found that some patients infected with novel coronavirus had palpitation, shortness of breath, chest pain, chest oppression, fatigue and other symptoms. Electrocardiogram(ECG) showed myocardial ischemia injury and increased myocardial enzymes, due to the pathological changes of warm pathogen, first invading the lung and reversely spreading to the heart. Myocardial injury due to infection of novel coronavirus, on the one hand, made the patients weak and conditions lingering and hard to heal after COVID-19 was recovered in discharged patients. On the other hand, myocardial injury in severe cases could easily aggravate the disease and even threaten life. According to the different stages of the disease, the severity of the disease, and the patients' physique in the recovery period, different treatment methods were adopted. For the myocardial injury in patients with acute severe COVID-19, Shengmaiyin and Emergency Huiyangtang can be taken， if the poisonous heat disturbs the mind, we can use Angong Niuhuangwan and Zhibaodan as appropriate. For myocardial injury occurred in common type of COVID-19, Zhuye Shigaotang and Shenxiantang can be used. For the pathological changes mainly including myocardial injury after clinical recovery of COVID-19, we can use Shengxiantang, Yangxintang, Chaixiantang and so on. Methods of detoxification, tonifying Qi and Yin, invigorating Qi and ascending Qi collapse, blood circulation and phlegm resolving were used for treatment of myocardial injury from COVID-19, which can not only effectively improve clinical symptoms, but also restore creatine kinase isoenzyme-MB(CPK-MB) and ECG levels to obtain satisfactory results. All of these could reflect that TCM has a notable advantage in the prevention and treatment of this disease.

Effects of Tanyu Tongzhi recipe on hemorheology, blood lipid and inflammatory factors in rats with mycardial ischemia-reperfusion injury and hyperlipidemia / 中国中药杂志

<p><b>OBJECTIVE</b>To investigate the influence of Tanyu Tongzhi (TYTZ) recipe on chemorheology, blood lipid and inflammatory factors of hyperlipidemia and myocardial ischemia-reperfusion injury in rats.</p><p><b>METHOD</b>Sixty SD male rats were divided into 5 groups randomly, sham-operated group, model group, high dose group of reproduced by ligation of left descending artery for 30 min followed by releasing the TYTZ and low group of TYTZ. The model of MI/RI injury of the myocardium was ligation for 2 hours in rats. Serum contents of CHO, TG, HDL-L, LDL-L and whole blood viscosity, plasma viscosity and ICAM-1, TNF-alpha, IL-10 were measured after myocardial reperfusion injury.</p><p><b>RESULT</b>Compared with sham-operated group, the levels of CHO, TG, LDL-L, whole blood viscosity (1.0,3.0) plasma viscosity and the contents of ICAM-1 were significantly higher, however, HDL-L, IL-10 levels were lower in model group (P < 0.01 and P < 0.05). CHO, TG, whole blood viscosity (1.0, 3.0, 30) and expression of ICAM-1, TNF-alpha were obviously lower in low group than the model group (P < 0.01 and P < 0.05).</p><p><b>CONCLUSION</b>The TYTZ recipe can relieve reperfusion injury through regulating blood lipid, improving hemorheological characteristic and inhibiting inflammatory reaction.</p>
