Objective: To observe the therapeutic effect of An-pressing and Rou-kneading manipulations for exercise fatigue of the anterior tibial muscle. Methods: Sixty healthy subjects were randomly divided into two groups, 30 in each group. Isokinetic test training was employed to induce left anterior tibial muscle fatigue. After this, subjects in the observation group received 5 min of tuina treatment, while subjects in the control group just lay down for 5 min. Then the integral myoelectricity, maximum amplitude, mean frequency and slope of the anterior tibial muscle and gastrocnemius muscle were measured using a surface electromyography (EMG) during the passive movements of the ankle joints in two groups. Results: Before treatment, the integral myoelectricity, maximum amplitude, mean frequency and slope of the anterior tibial muscle during exercise in two groups were consistent under isokinetic mode (P>0.05). After 5 min of tuina or rest, the myoelectric signals during exercise in two groups were both decreased. However, subjects in the observation group obtained a remarkably increased gain and gain rates of myoelectric signal than the control group (P<0.05). This indicates that the myoelectric signals were not fully recovered, but tuina has a better effect than rest on improving the myoelectric signal of the anterior tibia. Conclusion: Rest and tuina can both improve muscle fatigue. Tuina can obtain a better effect within the same time frame.

BACKGROUND:It has been demonstrated to be effective for the improvement of heart function after acute myocardial infarction with intravenous or intramyocardial administration of bone marrow mesenchymal stromal cels. However, little is known regarding the effect of the combination of intravenous and intramyocardial administration of mesenchymal stromal cels on the heart function of a chronic myocardial infarction model. OBJECTIVE:To study the effect of intravenous and intramyocardial administration of bone marrow mesenchymal stromal cels on the heart function of a rat chronic myocardial infarction model and the relevant mechanism. METHODS:Bone marrow mesenchymal stromal cels isolated from Lewis rats were expandedex vivo. BrdU-labeled bone marrow mesenchymal stromal cels (3×106) were administeredvia the femoral vein and the myocardial surface respectively into rat models of chronic myocardial infarction in cel transplantation group. The equal volume of PBS was injected into the same place in control group. Four weeks after injection, echocardiography was performed to evaluate the heart function, and then the heart tissues were harvested for immunohistochemistry examination. The total blood vessel density in the scar area was evaluated. RESULTS AND CONCLUSION:At 4 weeks after cel implantation, the left ventricular function was not improved in the two groups. The immunohistochemistry staining showed that (1) the mesenchymal stromal cels in the myocardium did not differentiate to myocardial cels; (2) there was no significant difference in the total blood vessel density in the scar area between the cel transplantation and control groups. Taken together, the combined intravenous and intramyocardial administration of bone marrow mesenchymal stromal cels cannot improve heart function in a rat chronic myocardial infarction model.
