"chi mi-byo (premorbidity) or zhi-weibing is defined as "preventive treatment of disease" in the "Annual Report on Health and Welfare 1997". In China, in the 2006 five-year plan for the "zhi-weibing" policy and in the 2008 "zhi-weibing" project, the policy has been changed in quality to emphasize prevention, "yo-jo or yangsheng (care of life)", and health for the purpose of improving lifestyle-related diseases and reducing the medical costs.
The word "zhi-weibing" is used in "Suwen" and "Ling Shu" in reference the following: prevention, "yangsheng", and the initial/early treatment at the onset of disease. Additionally in "Nanjing" and "Jingui Yaolue", "zhi-weibing" means predicting the change of disease and preventing the progress of disease. Furthermore in Kampo Ikkando Medicine in Japan, it means improvement of constitution.
In this symposium, I touched on the following:
Volunteer activity reports at disaster areas
Macroscopic viewpoint of current medical state (health issue in modern times)
The relationship of health, disease, and the power to cure oneself
"zhi-weibing or chi mi-byo"
The world of Tao (way, path) and Mei (life)
The "zhi-weibing" policy in China
Symposiasts spoke on topics as follows:
1) Ascertaining the history of "zhi-weibing or chi mi-byo" and terminological issues like "chi mi-byo" or "mi-byo chi" in Japan
2) As a clinical practice of "chi mi-byo", an approach to a part of various methods of "yangsheng or yo-jo" based on the power to cure oneself and holistic healing method, the initial treatment, preventing the progress of disease, and the improvement of constitution
3)Achievement of the initial treatment of "Jingei-Kiko pulse diagnosis" and checking "the pulsation type and clinical condition"
Whenever thinking about the future of the field of acupuncture and moxibustion, life quality of each and every human being, health, happiness, and medical economy, I would be much obliged if the contents of this "chi mi-byo" symposium are helpful to inspire medical care and the Society of Medicine, all healthcare professionals, and all patients.

 By using a simplified model for cardiovascular system which consists of the cardiac resistance R_h, the artery C_a, the vein C_b and the peripheral vessel R_s, the ratio of the arteriovenous pressure difference Δp to the maximum arteriovenous pressure difference Δp_M was defined as the circulatory ratio θ ≡Δp ⁄ Δp_M. It was shown that the circulatory ratio θ was θ=1 ⁄ 2 regardless of the exercise. It was revealed that this regulation is done by keeping R_h ⁄ R_s constant and the ratio is equal to the arterial compliance fraction k_a.

Thromboexclusion method for thoracic aortic aneurysm was studied in 10 patients who had dissecting aneurysm in 7 and atherosclerotic aneurysm in 3. The aortic aneurysms extended from the left subclavian artery to the diaphragma or more widely. The operations were extraanatomic bypass and permanent aortic clamp proximal to the aneurysm in 9, and proximal and distal to the aneuysm in one. The follow up periods were 14 days to 80 months. Eight patients survived more than 3 months and 5 of them had thromboexclusion of aneurysm to the diaphragma. One with the aneurysms of incomplete thromboexclusion resulted in aneurysmal rupture 28 months after operation, and recovered by additional clamp distal to the aneurysm. Another had aneurysmal rupture, and died 63 months after operation. A patient had the penetration of the clamp to the pulmonary artery, and died 12 months after operation. Temporary paraplegia occurred in a patient 15 months after operation. Two patients developed constipation without ileus. Any difference of blood pressure between upper and lower extremities was not recognized, and no patient had deterioration of renal function. Indication of this method should be strictly selected, and careful follow up study is mandatory.
