Objective To explore the effect of acupoint injection of bone marrow mesenchymal stem cells (BMSCs)on hemodynamics of rat model with acute myocardial infarction(AMI). Methods Sixty Sprague-Dawley (SD)rats were randomly divided into sham group,model group,myocardium injection BMSCs group and acupoint injection BMSCs group(each n=15). The left anterior descending coronary artery(LAD)was ligated to establish a rat model of AMI. After the rat model was successfully established for 72 hours,0.2 ml BMSCs(1×1010/L)were transplanted by a micro-quantity syringe at 6 points in equal amount in the LAD blood-supply area and its periphery in the myocardial injection group,while in the acupoint injection group,0.3 ml BMSCs(1×1010/L)was transplanted at each of the following acupoints:Xinshu,Zhiyang and Tanzhong. Four weeks after AMI,polyethylene tubing was inserted into the right carotid artery to measure the hemodynamics,at the same time animals were sacrificed,and the heart was take out to calculate the heart mass index(HMI)and left ventricular mass index(LVMI). Results One, 3,5 and 4 rats were respectively dead in the sham group,model group,myocardium injection group,and acupoint injection group during the experimental period. Compared with the sham group,the left ventricular systolic pressure (LVSP,mm Hg,1 mm Hg=0.133 kPa),the maximum rate of increase of left ventricular pressure(+dp/dt max, mm Hg/s), the maximum rate of decrease of left ventricular pressure(-dp/dt max,mm Hg/s), the maximum logarithmic change rate of left ventricular pressure〔(dp/dt)?P-1max,s-1〕,HMI(mg/g),LVMI were significantly decreased,and left ventricular end-diastolic pressure(LVEDP,mm Hg),heart rate(HR,bpm)were obviously increased in model group(all P<0.05). Compared with the model group,the LVSP,+dp/dt max,-dp/dt max, (dp/dt)?P-1max, HMI,LVMI were significantly increased in myocardial injection group and acupoint injection group〔LVSP:130.38±14.96,124.36±14.36 vs. 114.36±12.71,+dp/dt max:4707.52±394.36,4597.14±411.05 vs. 3791.43±327.29,-dp/dt max:4075.11±317.89,3938.05±373.76 vs. 3116.32±275.04,(dp/dt)?P-1max:215.26±21.29,197.39±18.96 vs. 155.93±25.14〕,and the LVEDP and HR were significantly decreased(LVEDP:5.15±2.39,5.64±1.96 vs. 10.58±2.49,HR:400.50±42.58,395.55±44.62 vs. 414.51±35.75,all P<0.05). There were no significant differences in above indexes between myocardium injection group and acupoint injection group. Conclusion Acupoint injection of BMSCs can improve the heart function of rat model with AMI.

Objective To compare the effects of paired associative stimulation (PAS) and repetitive transcranial magnetic stimulation (rTMS) on motor cortex excitability.Methods The baseline corticospinal excitability of the left hemispheres of 10 healthy subjects was measured in terms of resting motor threshold (RMT) and other indicators of motor evoked potentials (MEP).On the following day they received PAS composed of trascranial magnetic stimulation (TMS) to the motor cortex of the left hemisphere and electric stimulation (ES) of the median nerve contralateral to the motor cortex,with an interval of 10ms between the TMS and ES (termed PAS10).The PAS10 was delivered at a frequency of 0.05 Hz and an intensity of 120％ of the RMT,for a total of 90 pulses.The MEP amplitude,MEP latency and RMT were evaluated one minute after the stimulation.After the PAS intervention,an interval of one week was allowed to eliminate any effect of PAS on motor cortex excitability.Then rTMS was delivered to the subjects' left motor cortex at the same time of day at a frequency of 1 Hz and an intensity of 120％ of the RMT,for a total of 1000 pulses.MEP amplitude,MEP latency and RMT were evaluated one minute after the stimulation.The two interventions were compared in terms of MEP amplitude,MEP latency and RMT.Results The average MEP amplitude,MEP latency and RMT at baseline were (2.93 ± 0.99) mV,(20.97 ± 1.67) ms,and (46.06 ±5.32) ％,respectively.One minute after PAS10,the MEP amplitude,MEP latency and RMT were (1.14 ± 0.76) mV,(21.87 ± 1.09) ms and (52.06 ±4.20) ％,respectively.One minute after rTMS,the MEP amplitude and latency and the RMT were (2.24 ± 0.79) mV,(20.88 ± 1.94) ms,and (49.00 ± 4.54) ％,respectively.The differences in MEP amplitude,MEP latency and RMT pre-and post-intervention were (0.69 ± 0.10) mV,(0.09 ±0.05) ms and (3.94 ± 0.93) ％,respectively for rTMS.For PAS10 they were (1.83 ± 0.14) mV,(0.90 ± 0.26)ms and (6.00 ± 1.13)％,respectively.The differences in MEP amplitude decrease and MEP latency lengthening between the two stimulation protocols were significant,but the difference in RMT elevation was not.Conclusion Both PAS10 and low frequency rTMS suppressed motor cortex excitability,but the suppressive effect of PAS10 is more significant.
