The three points of the Heart Meridian are "Shenmen" (HT 7), "Lingdao" (HT 4) and one point between HT 7 and HT 4, the 3 points of the Lung Meridian are "Taiyuan"(LU 9), Lieque (LU 7) and one point between LU 9 and LU 7. These points are punctured with filiform needles and stimulated electrically by setting the parameters being frequency of 2.5 Hz, dense sparse waves and duration of 10 min. Results display that the regulative effect of EA of the Heart Meridian is superior to that of EA of the Lung Meridian on the three indexes, showing a closer correlation between the whole Heart Meridian and activities of ECG, SIG and EEG.展开更多

The direct relationship between the liver and the gall bladder and between the kidneys and the bladder is recognised and accepted in both Chinese and Western Medicine. This is not the case with the pairings which in Eastern morphophisiology are formed by the heart and small intestine and the lungs and large intestine. These pairings are not recognised in Western Medicine. The writer in her dual capacity of Doctor of Western Medicine and acupuncturist is investigating the reasons why in Chinese Medicine the heart and small intestine and their meridians form a relation which couples them. For this the comparative method was used between data from Western anatomy which demonstrate the interorganic and functional relation between the small intestine and the heart and the Chinese energy dynamic of the corresponding zangfu and jingluo. Biomedicine which does not relate the heart with the small intestine brings in the materiality of its anatomic descriptions which are valuable for the interpretation of Oriental Medicine. This interrelation between the two organs and their meridians are well explicated in Chinese Medicine whose traditional concepts in this respect are corroborated by Western anatomical descriptions which, nevertheless, do not admit the functional-organic coupling of the heart and small intestine.展开更多

The enhanced cardiovascular risk in this group of patients may be related to adverse autonomic imprinting by early life stress. Autonomic dysfunction and possible effects of growth hormone therapy on the autonomic nervous system can be measured easily by calculating heart rate variability (HRV) from Holter electrocardiogram monitoring. Methods: We performed HRV analysis prior to growth hormone therapy (N = 33), within the first year of growth hormone therapy between 4 and 10 years of age (N = 19), at least a further HRV measurement between 10 and 15 years (N = 30). Additional measurements were performed before and after cessation of growth hormone therapy (N = 14). Data were compared to untreated pediatric patients with short stature and to age matched healthy controls. Results: Untreated patients with short stature due to growth hormone deficiency or intrauterine growth restriction in early childhood have significantly increased heart rates most of all at night and concomitantly reduced global HRV indicated as Standard Deviation of Normal to Normal Intervals (SDNN). Growth hormone treated adolescents and the untreated patients with short stature show significantly elevated mean heart rates and concomitantly reduced vagus activities measured as reduced Route Mean Square Standard Deviation (RMSSD). After cessation of growth hormone treatment SDNN significantly increases and heart rate decreases to normal values in formerly treated patients with catch-up growth. Conclusion: There is a comparable autonomic dysfunction in treated and untreated children with short stature as an indicator for enhanced cardiovascular risk. After cessation of growth hormone therapy, we found a significant improvement of reduced HRV to normal values.展开更多
