The effects of QDPTP on cerebral blood flow and artery blood pressure in anesthetized rats The regional cerebral blood flow in cerebral pia mater was examined by Laser Doppler Flowmeter and the artery blood pressure (including mean systolic pressure, mean diastolic pressure and mean blood pressure) were monitored by the electrophysiological polygraph before and after drug administration.

结果表明：模型组脑组织及血清IL1-β含量分别为1006.4±247.1 pg/ml和370.8±76.6 pg/ml，与之相比，QDPTP中剂量(550.7±99.8，268±64.6)组中脑组织及血清中IL1-β的含量显著降低(P.01)，川芎嗪脑也明显减少组织IL1-β的含量(627.8±144.7，P.05)。 QDPTP对麻醉大鼠局部脑血流量和动脉血压的影响采用激光多普勒血流仪测量大鼠软脑膜局部的血灌注量，其被视为局部的脑血流量。

Methods:43 patients including 10 with mitral stenosis associated aortic regurgitation, 12 with mixed mitral valve lesions and 21 with mixed mitral valve lesions and combined with aortic regurgitation were studied.MVA determinded by (1) two -dimensional echocardiography with a cross-sectional area in the short-axis view (2DE),(2) pressure half-time using formula of 220/PHT,(3) color Doppler flow imaging with a jet cross-sectional area in the short-axis view with planimetry,(4) CDFI with a color jet width at the mitral valve orifice in the apical four-chamber view and long-axis view, assuming an elliptic mitral orifice, compared with the orifice area of excised mitral valve during mitral valve replacement.
