[Coronary heart disease: innovative understanding from traditional Chinese medicine and treatment by classic formulas].

Coronary heart disease is a common cardiovascular disease, attacking about 11.4 million patients in China. With increasing prevalence and mortality year by year, coronary heart disease has become a major factor threatening human health and public health. Although primary and secondary prevention, intervention, coronary artery bypass grafting and other interventions have reduced the death rate, there are drug(aspirin) resistance, secondary nitroglycerin failure, post-intervention fatigue, chest tightness, and an-xiety, and complication with a high risk of bleeding, which have become the key clinical and scientific issues needed to be resolved. Coronary heart disease belongs to the category of chest impediment and heart pain in traditional Chinese medicine(TCM). The TCM etiology of this disease includes external contraction of cold, emotional disorders, constitutional insufficiency, physical weakness, and labor injury, which are closely related to sympathetic nerve activity, state of cardiac and psychological diseases, family history, and cardiovascular metabolic disorders in modern medicine. The TCM causes of coronary heart disease include Qi depression, phlegm turbidity, blood stasis, fire-heat, cold congealing, and healthy Qi deficiency, which are associated with emotional factors such as anxiety and depression, abnormal lipid metabolism, abnormalities in blood circulation and coagulation, inflammatory responses, hyperactive immune responses, and heart failure, chronic wasting disease, or aging, respectively. Accordingly, the patients with Qi depression should be treated with Chaihu Longgu Muli Decoction, and those with phlegm turbidity should be treated with Wendan Decoction and Gualou Xiebai Banxia Decoction. Xuefu Zhuyu Decoction and Guizhi Fuling Pills are recommended for blood stasis, Xiaoxianxiong Decoction and Sanhuang Xiexin Decoction for fire-heat, Zhishi Xiebai Guizhi Decoction for cold congealing, and Renshen Decoction for healthy Qi deficiency. Due to the changes in the spectrum of diseases from ancient to modern times as well as the differences in physical constitution, the key cause of coronary heart disease has evolved from the chest Yang deficiency and cold congealing to Qi depression, phlegm turbidity, phlegm combined with stasis, and fire-heat, showing a shift from cold to heat and from deficiency to excess. The combination of classic formulas presents a pattern. That is, the core formula-syndrome correspondence of a disease often fixedly appears with other formula-syndrome correspondence, which may be related to the development of the pathophysiological mechanism of the disease. In the clinical application of modern pharmacological results, the research team has formulated the clinical principle of pathogenesis corresponding to pathological changes and medicinal nature corresponding pharmacological effects. The modern pharmacological research on classic formulas is conducive to targeted treatment. Moreover, classic formulas help to ameliorate aspirin resistance, clopidogrel resistance, post-intervention anxiety, and high risk of bleeding and address the lack of effective blockade of critical lesions in the coronary artery and the progression of post-infarction heart failure. The innovative understanding of the etiology and pathogenesis of co-ronary heart disease helps to improve the clinical efficacy of TCM and the clinical system for treating coronary heart disease with classic formulas.

[Arrhythmia:innovative understanding from traditional Chinese medicine and treatment by classic herbal formulas].

Arrhythmia, a common and frequently occurring cardiovascular disease, causes a heavy burden on the public health of China. Approximately 20 million patients are suffering from this disease in China and treated by pharmacological and surgical therapies. However, antiarrhythmic drugs can cause arrhythmia and surgical treatment has the risks of failure and recurrence. Therefore, the clinical outcome of arrhythmia remains to be improved. According to the traditional Chinese medicine(TCM) theory, arrhythmia is a disease of palpitation induced by 7 conditions: liver depression and Qi stagnation, accumulation of turbid phlegm, fluid retention attacking the heart, fire-heat disturbing the heart, stasis obstruction of heart vessel, cold congealing in heart vessel, and the deficiency of Qi, blood, Yin, and Yang. Therefore, this study concisely proposed 7 TCM syndromes of arrhythmia, including the palpitation due to depression, phlegm, fluid retention, fire, blood stasis, cold, and deficiency. The corresponding treatment strategies were recommended as follows: Chaihu Longgu Muli Decoction for the palpitation due to depression, Wendan Decoction for the palpitation due to phlegm, Linggui Zhugan Decoction for the palpitation due to fluid retention, Sanhuang Xiexin Decoction for the palpitation due to fire, Xuefu Zhuyu Decoction for the palpitation due to blood stasis, and Mahuang Fuzi Xixin Decoction for the palpitation due to cold, and Guizhi Gancao Decoction, Guizhi Gancao Longgu Muli Decoction, Huanglian Ejiao Decoction, Zhigancao Decoction, and Guipi Decoction for the palpitation due to the deficiency of Qi, blood, Yin, and Yang. Multiple formulas should be combined if the patient presents several TCM syndromes simultaneously. According to the principles of the correspondence between formula and syndrome and the treatment with consideration to both pathogenesis and pathology and both herbal nature and pharmacology, this study proposed an integrated treatment model of "pathogenesis-pathology-nature-pharmacology" to enhance the clinical efficacy of classic herbal formulas in the treatment of arrhythmia.

[Research ideas of core formulas-syndromes based on disease-syndrome-treatment combination].

The relationship between disease and syndrome is a research focus in integrated traditional Chinese and western medicine. Depending on the focus, the disease-syndrome combination for treatment is manifested as the different treatment methods for the same disease and the same treatment method for different diseases based on the syndrome, and different treatment methods for the same syndrome and the same treatment method for different syndromes based on the disease. The mainstream model is the combination of di-sease identification in modern medicine with syndrome identification and core pathogenesis in traditional Chinese medicine. However, current research on the combination of disease and syndrome and core pathogenesis tends to focus on the heterogeneity between disease and syndrome and the separation of syndrome and treatment. Therefore, the study proposed the research idea and model of core formulas-syndromes(CFS). According to the theory of formula-syndrome correspondence, the research idea of CFS deepens the research on core pathogenesis, which aims to summarize the core formulas and syndromes for diseases. The research fields include diagnostic criteria for the indications of formulas, distribution patterns of formulas and syndromes for diseases, the evolution of medicinal-syndrome based on formulas-syndromes, formula combination law based on formulas-syndromes, and the dynamic evolution of formulas-syndromes. Through the summary of ancient classics, clinical experience, and medical records, and with the methods of expert consultation, factor analysis, and clustering analysis, research on the diagnostic criteria for the indications of formulas aims to explore the diagnosis information such as the diseases, symptoms, signs, and pathophysiology. The research on the distribution patterns of formulas and syndromes for diseases tends to summarize the specific types of formulas and syndromes for the diseases through literature research and clinical cross-sectional studies based on the establishment of diagnostic criteria for the indications of formulas. The research on the evolution of medicinal-syndrome aims to clarify the medicinal-syndrome law through literature and clinical research. The formula combination law refers to the fact that the core prescriptions for a disease often appear in combination with other prescriptions on a regular basis. The dynamic evolution of formulas-syndromes refers to the continuous transformation and change of formulas and syndromes in the process of disease development with changes in time and space. The CFS is conducive to the unification of disease, syndrome and treatment and to the deepening of the research model of disease and syndrome integration.

[TCM understanding and treatment strategy of hypertension complicated with sexual dysfunction].

Hypertension and its target organ damage have become a major public health problem. Sexual dysfunction is a new problem in the treatment of modern hypertension. Modern pathophysiological studies have shown that hypertension can lead to sexual dysfunction. In addition, three major hypotensive drugs represented by diuretics can also lead to sexual dysfunction. In traditional Chinese medicine(TCM), hypertension belongs to "vertigo" "headache" "head wind", etc. In the past, the understanding of the TCM pathogenesis of hypertension was mainly from the perspectives of "liver wind" and "Yang hyperactivity". However, based on the in-depth research on ancient and modern literature and medical records and many years of clinical practice, it has been identified that kidney deficiency was the key pathogenesis. Hypertension complicated with sexual dysfunction belongs to the category of kidney deficiency syndrome in TCM, especially the deficiency of kidney Yin. Previous studies by other research groups showed that Yin-enriching and kidney-tonifying method could effectively reduce blood pressure, improve sexual dysfunction, reverse risk factors, and protect target organs. This article systematically discussed the TCM understanding, modern pathophysiological mechanism, and the clinical treatment strategy of kidney-tonifying drugs(single drugs and compounds) in the treatment of hypertension complicated with sexual dysfunction in order to provide a scientific basis for kidney-tonifying method in the treatment of hypertension complicated with sexual dysfunction.

[Adsorption-desorption performance of honeycomb-shaped activated carbon].

Honeycomb-shaped activated carbon is useful to control organic gas pollution of large air-flow and low concentration. Effects of adsorbents, toluene concentration, velocity of empty bed and temperature of desorption on its adsorption-desorption performance were studied by conducting on dynamic experiments. Results shown that adsorption properties of honeycomb-shaped activated carbon were increased with decreasing of the inlet toluene concentration under the condition of certain outlet toluene concentration, and gas velocity of empty bed was recommend as 1.2-1.8 m x s(-1). With increasing of the desorption temperature, the outlet toluene concentration appeared peak-value and fluctuated widely, and the recommended desorption temperature was 90 degrees C. Gas velocity of empty bed affected the peak value of concentration of the toluene, and practical value was 0.2-0.4 m x s(-1).

[Analysis of the treatment technology pathway of VOCs released from oven].

Treatment of VOCs from oven of container production process is taken as an example to discuss the characteristics of regenerative thermo oxidation (RTO)-heat recovery technology and activated carbon adsorption-steam desorption-solvent recovery technology, based on a large number of data gathered in many projects. It is suggested that, both of technologies are able to achieve the purpose of recovery VOCs; Compared with activated carbon adsorption-steam desorption-solvent recovery technology, RTO-heat recovery technology has better economic and environmental benefit.
