ABSTRACT
<p><b>OBJECTIVE</b>To observe the effects of moxibustion on factors related with apoptosis of myocardial cells after sports fatigue in mice as well as the relationship among histone acetyltransferases p300 (p300), CREB binding protein (CBP) and cell apoptosis to discuss the role of p300 and CBP in moxibustion against apoptosis of myocardial cells.</p><p><b>METHODS</b>Sixty clean-grade male Kunming mice were randomly divided into a control group, a sport group and a moxibustion group, 20 cases in each one. Mice in all group received identical feeding environment. Mice in the control group did not received sport nor moxibustion; mice in the sport group and moxibustion group received non-weight swimming training which lasted from 30 min per day to 90 min per day gradually for 21 days; 1 h after swimming training, mice in the moxibustion group received moxibustion with seed-sized moxa cone at "Zusanli" (ST 36) and "Guanyuan" (CV 4), 5 cones at each acupoint, once a day for 21 days. 24 h after the final swimming training, cardiac muscle tissue was collected to test factor associated suicide (Fas), B cell lymphoma/lewkmia-2 (Bcl-2) by immunohistochemical method and expression of p300 and CBP.</p><p><b>RESULTS</b>Compared with the control group, the apoptosis rate of myocardial cells in the sport group was significantly increased (P<0.01), and apoptosis body with dense distribution and deep coloring can be seen in the field of microscope; the expression of Fas protein was significantly increased (P<0.01), and expression of Bcl-2, p300 and CBP was reduced (all P<0.01). The equally distributed apoptosis body with slight coloring was seen in the moxibustion group. Compared with the sport group, the apoptosis rate of myocardial cells in the moxibustion group was significantly reduced (P<0.05); the expression of Fas protein was significantly reduced (P<0.05), and expression of Bcl-2, p300 and CBP was increased (all P<0.05).</p><p><b>CONCLUSION</b>Moxibustion could promote the expression of p300 and CBP in myocardial cells after sports fatigue in mice to inhibit the starting of apoptotic process, therefore reducing the apoptosis of myocardial cells after heavy exercise and protecting heart function.</p>
