Based on the syndrome and treatment system of collateral disease， and inheriting the development of the bloodline theory of traditional Chinese medicine （TCM）， academician WU Yi-ling systematically constructed the vessel-collateral theory of TCM and proposed that its core theory was the theory of Yingwei， that is， "Ying in the vein， and Wei outside the vein" （Huangdi Neijing·Lingshu·Yingwei Shenghui）， "obstructing of Yingwei， congelation of blood" （Treatise on Febrile Diseases· Pulse Differentiation Method）， "pathogen transferring through blood vessels， obstructed by blocking" （Jinkui Yaolue·Zangfu Jingluo Xianhou Bingmaizheng First）， and "damage of the heart， adjust its Yingwei". Based on the consistency of vessel-collateral as the channel of blood circulation in TCM with the blood vessels in western medicine， and guided by the Yingwei theory of vessel-collateral theory， the diagnostic criteria of syndrome differentiation of disease of vessel-collateral and vascular system represented by coronary heart disease， arrhythmia， heart failure and others was established to guide the prevention and treatment of vascular diseases. Based on the above analysis， guided by the Yingwei theory of vessel-collateral theory， and on the basis of related researches of vessel-collateral and vascular system， this paper discussed the etiology and pathogenesis of chronic coronary syndrome （CCS） in TCM. Taking useful collateral with unblocking as the treatment principle， the representative Tongluo prescription （Tongxinluo） was constructed， the research progress of Tongxinluo from various aspects such as animal experiment research， pharmacological research and clinical evidence-based research was summarized， a comprehensive system from etiology， pathogenesis， syndrome differentiation to treatment was formed， in order to provide new ideas for the clinical treatment of CCS.

Meridians include (Qi) channels and blood (vessels). In Duyi Suibi, ZHOU Xue-hai of qing Dynasty named the terminal of Qi channel as"fine collateral of Qi" and the terminal of blood vessel as"fine collateral of blood". Qi channels of the heart cover extensive regulating mechanisms including cardiac pacing and conducting system. Blood vessels of the heart cover circulation system of coronary artery. Cardiac Qi channels and blood vessels are coordinated mutually, and Ying and Wei run together, to jointly maintain normal functions of the heart. Abnormal Yingwei caused by various pathogenic factors leads to occurrence of arrhythmia. Based on the Yingwei theory of vessel-collateral theory, this paper puts forward treatment based on syndrome differentiation of arrhythmia guided by therapeutic principle of"regulating Yingwei in case of heart damage" (Nanjing·14^thNan) as well as addresses both symptoms and root causes by prescriptions for regulating Wei, Qi, Ying and blood through sufficiently considering modern pathogenic factors and pathogenic characteristics, in order to provide beneficial reference for clinical diagnosis and treatment.

ObjectiveExploring the formula rules of commonly used traditional Chinese medicines（TCMs） for epidemic treatment from the Qin and Han dynasties to the Qing dynasty through data mining， providing reference for the prevention and control of contemporary epidemics. MethodsThe articles on epidemic treatment in the electronic database of Chinese Medical Code V5.0 were systematically searched， and the contents such as source， dynasty， author， diagnosis， formula name， therapeutic method and efficacy， and composition of medicines from each article that met the inclusion criteria were extracted. Then， an Excel standardized database was established， and Python programs were used for data mining to summarize the frequency of commonly used medicines and perform hierarchical cluster analysis， Pearson correlation analysis， and association rule analysis. ResultsA total of 1 595 formulas were included， involving 558 TCMs. The efficacy of these medicines could be classified into two categories， namely， expeling pathogenic factors and reinforcing healthy Qi. According to the frequency deconstruction analysis， high-frequency medicines were mainly detoxification， Fu-organ dredging， aromatization and promoting blood circulation， followed by the medicines with the effect of treating the lungs， such as clearing the lungs and resolving phlegm， clearing heat and purging the lungs， relieving cough and asthma， and purging the lungs and relieving asthma. And the proportions of acrid-warm herbs and acrid-cold herbs varied in different periods. Hierarchical clustering and correlation analysis both suggested TCMs for expeling pathogenic factors and reinforcing healthy Qi often formed stable combinations with high association degrees. Association rule analysis showed that the core acrid-warm herb was mainly Ephedrae Herba， and the core acrid-cold herb was mainly Forsythiae Fructus， resulting in the core formulas of Maxing Shigantang and Yinqiaosan. ConclusionThroughout history， the prevention and control of epidemics have been based on the principle of "preserving healthy Qi and avoiding toxic Qi"， focusing on the treatment of the causes and characteristics of epidemics through detoxification， Fu-organ dredging， and aromatization， emphasizing the use of Rhei Radix et Rhizoma and other herbs to dredge Fu-organ， eliminate toxins and pathogens， and playing the role of actively intervene with symptomatic medication. And based on the external manifestations of the body's struggle between evil and righteousness， diagnose and treatment according to syndrome differentiation was performed.

Optimizing the structure of ethics committee, strengthen the training and assessment of members, can effectively enhance the ability of ethics committee review. Unifing the list of documents, optimizing the work flow and the way of examination can effectively shorten the period of ethical examination. It is suggested that continuous ethical training and assessment should be carried out, that an information-based platform system should be used to achieve dynamic supervision, and that a certification system and assessment mechanism for ethics committees should be established at the national level, to promote the improvement of the ability of ethical review.

Diabetic retinopathy（DR）， as one of the most common and serious microvascular complications of diabetes mellitus， seriously threatens human health， and belongs to "Xiaoke eye diseases" in traditional Chinese medicine（TCM）， which has been richly experienced by medical practitioners through the ages， but is mostly recorded in a piecemeal manner and has not been systematically researched. This disease is featured by long course and repeated attack， and is refractory， which belongs to the research category of "persistent illness entering collaterals". Systematic establishment of TCM collateral disease theory for guiding prevention and treatment of DR has important clinical value. On the basis of close correlation between tertiary collaterals at the terminal of collaterals and capillaries and microcirculation， the concept of "tertiary collaterals-microvascular" is proposed. It is pointed out that DR falls within the scope of "tertiary collaterals-microvascular" diseases， and presents four types of micro-pathological characteristics， including stasis， insufficiency， growth and bleeding of tertiary collaterals. It is concluded that "deficiency of both Qi and Yin" is the basic pathogenesis of DR， and "blood stasis and collateral obstruction" is the important pathogenesis and key factor. Thus， the treatment method of "dispersing blood stasis， dredging collateral， tonifying Qi and Yin， stopping hemorrhage and improving eyesight" is determined， and the formula of Tongluo Mingmu capsules is developed. The article tightly focuses on the pathological changes such as stasis， growth， insufficiency and bleeding of collaterals， addresses both symptoms and root causes， and plays a synergistic role of both dispersing stasis and stopping bleeding. In this way， it can realize the purpose of tonifying Qi and Yin to replenish the essence， dispersing stasis and dredging collaterals to meet the requirement， as well as stopping hemorrhage and improving eyesight to deal with changes. Fundamental researches demonstrate that Tongluo Mingmu capsules has synergy effects of protecting both retinal capillaries and retinal cells. Phase-Ⅲ clinical trial of new drug has proven definite clinical efficacy and good safety， which provides a new drug choice for enhancing clinical effect of DR， and further supports the scientific value of Luobing theory in preventing and treating DR and other clinically significant diseases.
