The authors evaluated the association of serum uric acid （SUA） levels with adverse cardiovascular events and deaths in an elderly population affected by advanced atherosclerosis. They founded meaningful association between SUA levels and of cardiovascular events and cancer related death. We believe that these findings will lead for further studies on uric acid.展开更多

However, their combined ef- fect on mortality in stages of hypertension according to updated clinical guidelines among dderly population is unclear. Methods We fol- lowed a cohort of 6100 residents （2600 males and 3500 females） of Kangwha County, Korea, ranging from 55 to 99 year-olds as of March 1985, for all-cause and cardiovascular mortality for 20.8 years until December 31, 2005. Mortality data were collected through telephone calls and visits （to 1991）, and were confirmed by death record matching with the National Statistical Office （1992-2005）. Hazard ratios were calculated for all-cause and cardiovascular mortality by resting heart rate and hypertension defined by Eighth Joint National Committee crite- ria using the Cox proportional hazard model after controlling for confounding factors. Results The hazard ratios associated with resting heart rate 〉 80 beats/min were higher in hypertensive men compared with normotensives with heart rate of 61-79 beats/rain, with hazard ratios values of 1.43 （95% CI： 1.00-1.92） on all-cause mortality for prehypertension, 3.01 （95% CI： 1.07-8.28） on cardiovascular mortality for prehypertension, and 8.34 （95% CI： 2.52-28.19） for stage 2 hypertension. Increased risk （HR： 3.54, 95% CI： 1.16-9.21） was observed among those with both a resting heart rate 〉 80 beats/rain and prehypertension on cardiovascular mortality in women. Conclusions Indi- viduals with coexisting elevated resting heart rate and hypertension, even in prehypertension, have a greater risk for all-cause and cardiovas- cular mortality compared to those with elevated resting heart rate or hypertension alone. These findings suggest that elevated resting heart rate should not be regarded as a less serious risk factor in elderly hypertensive patients.展开更多

Under the auditory evoked brain stem potential (ABP) examination, the latent period of V wave and the intermittent periods of III-V peak and I-V peak were significantly shortened in Parkinson's disease patients of the treatment group (N=29) after acupuncture treatment. The difference of cumulative scores in Webster's scale was also decreased in correlation analysis. The increase of dopamine in the brain and the excitability of the dopamine neurons may contribute to the therapeutic effects, in TCM terms, of subduing the pathogenic wind and tranquilizing the mind.……展开更多
