Are onset age and severity of motor impairment associated with reduction of myocardial 123I-MIBG uptake in Parkinson 's disease?
This study suggests that late onset, high severity PD is associated with myocardial sympathetic dysfunction.
Chinese workers on the epidemiology and prevention of HFRS in China have accomplished great achievements since 1981. As the relatively high annual incidence of HFRS sustained in recent years, control measures have to be reinforced. Many problems of HFRS and hantavirus infections are still not well understood or unclear, such as the poly-host nature, and the multi-modes of transmission, the natural history of hantaviruses and their genetic variation occurred in nature etc. The task for effective control of HFRS and the research on its epidemiology in China should be held on a high priority.
