Objective To study the effect of Qiangxin Fumai Granule (QXFMG) on rabbits induced with acute injury of sinoatrial node. Method 50 rabbits were divided into five groups-control group, QXFMG low dose group, QXFMG middle dose group, QXFMG high dose group and atropine group. The group on experiment was given QXFMG, and the active control group was given atropine. Result QXFMG can raise the heart rates, improve the function of sinoatrial node, thus speed up pacing frequency, and cause the consersion of ectopic cardiac rhythm into sinus rhythm, and then improve the cardiac muscle ischemic of the rabbits and speed the metabolization of cardiac muscle cellular. Conclusion QXFMG has the effect of raising heart rates and improving the cardiac muscle ischemic.

Objective To study the relationship between circadian rhythm varlation of blood pressure and TCM syndrome pattern in old age essential hypertension. Methods One hundred and sixteen cases of old age essential hypertension were selected,their circadian rhythm varlation of blood pressure and TCM syndromes were determined. Results The daytime systolic blood pressure was increased in the pattern with hyperactivity of liver-fire syndrome,there was difference compared with qi and yin deficiency pattern (P
