The Crustal Movement Observation Network of China （CMONOC）, which includes GNSS stations across China's Mainland, enables the continuous monitoring of the ionosphere over China as accurately as possible. A series of approaches for GNSS-based ionospheric remote sensing and software has been proposed and devel- oped by the Institute of Geodesy and Geophysics （IGG） in Wuhan. Related achievements include the retrieval of ionospheric observables from raw GNSS data, differential code biases estimations in satellites and receivers, models of local and regional ionospheric TEC, and algorithms of ionospheric tomography. Based on these achievements, a software for processing GNSS data to determine the variations in ionospheric TEC and IED over China has been designed and developed by IGG. This software has also been installed at the CMONOC data centers belonging to the China Earthquake Administration and China Meteorological Administration. This paper briefly introduces the related research achievements and indicates potential directions of future work.展开更多
The effect of Heart-protecting Musk Pill(HMP) on blood perfusion of the ischemic myocardi-um by intravenous dipyridamole 99mTc-sestamibi single photon emission computerized tomography (99mTc-MIBISPECT) in 17 patients ...The effect of Heart-protecting Musk Pill(HMP) on blood perfusion of the ischemic myocardi-um by intravenous dipyridamole 99mTc-sestamibi single photon emission computerized tomography (99mTc-MIBISPECT) in 17 patients with coronary heart disease was observed. Results showed that sublingual admin-istration of HMP prior to injection of dipyridamole could remit the cardiac symptoms induced by dipyridamole,such as angina, chest distress, etc. with a remission rate of 85% . HMP could also improve the SPECT imagedefect significantly, 8 of 11 cases with reversible image defects and 4 of 6 irreversible image defects wereimproved. It suggested that HMP could improve the blood perfusion of the ischemic myocardium, the total ef-fective rate was70 . 59 % . No adverse reaction was found.展开更多
