Impact on the gait time cycle of ischemic stroke in the treatment with yin-yang respiratory reinforcing and reducing needling technique / 中国针灸

<p><b>OBJECTIVE</b>To compare the difference in the efficacy on gait time cycle of ischemic stroke between yin-yang respiratory reinforcing and reducing needling technique (yin-yang needling) and the conventional acupuncture.</p><p><b>METHODS</b>Sixty cases of ischemic stroke were randomized into a conventional acupuncture group and a yin-yang needling group, 30 cases in each one. The basic treatment (the control of blood pressure, blood sugar and blood lipid, the intravenous drops of ginkgo leaf extract and dipyridamole injection and vinpocetine injection) were applied in the two groups. Additionally, in the conventional acupuncture group, the acupoints of the Stomach Meridian of Foot-Yangming [Biguan (ST 31), Liangqiu (ST 34), Zusanli (ST 36), Shangjuxu (ST 37), Xiajuxu (ST 39), etc.] were selected and stimulated with the even needling technique. In the yin-yang needling group, the acupoints of yin meridians such as Zuwuli (LR 10), Xuehai (SP 10), Yinlingquan (SP 9) and Sanyinjiao (SP 6), etc. and the acupoints of yang meridians such as Biguan (ST 31), Liangqiu (ST 34) and Yanglingquan (GB 34), etc. were selected. The reducing manipulation of respiratory reinforcing and reducing technique was applied to the acupoints of yin meridians and the reinforcing manipulation was applied to the acupoints of yang meridians. The kinematics time parameters were determined and compared before and 4 weeks after treatment.</p><p><b>RESULTS</b>After treatment, the differences in the gait cycle, the phase time of standing (%), the phase time of single support (%), the phase time of unilateral sway (%) on the affected (healthy) foot and phase time of double support (%) were significant as compared with those before treatment in the patients of the two groups (all P < 0.05), in which, the gait cycle (1.75 +/- 0.21 vs 2.02 +/- 0.37), the phase time of standing (%) on the affected (healthy) foot [(65.41 +/- 5.20)% vs (68.37 +/- 6.24)%, (70.99 +/- 6.47)% vs (74.51 +/- 5.19)%], the phase time of unilateral sway (%) on the affected (healthy) foot [(36.08 +/- 4.86)% vs (33.65 +/- 2.94)%, (31.04 +/- 3.41)% vs (26.77 +/- 2.67)%] and the phase time of double support (%) [(36.91 +/- 5.10)% vs (41.22 +/- 5.39)%] in the yin-yang needling group were improved much obviously after treatment as compared with those in the conventional acupuncture group. The differences in support phase time (%), single support phase time (%) and sway phase time (%) were significant between the affected limb and healthy limb of the two groups after treatment (all P < 0.05).</p><p><b>CONCLUSION</b>Yin-yang respiratory reinforcing and reducing needling technique effectively improves hemiplegic gait movement cycle and walking function in patients of ischemic stroke, which is superior to the conventional acupuncture treatment.</p>

Impacts of yin-yang meridians acupuncture with respiratory reinforcing and reducing manipulation on lower limbs balance function in stroke patients / 中国针灸

<p><b>OBJECTIVE</b>To observe the impact on lower limbs balance function in treatment of yin-yang meridians acupuncture with respiratory reinforcing and reducing manipulation involved in the patients of stroke by applying B-PHY balance function test training system so as to provide the objective evidence in treatment of stroke; with acupuncture.</p><p><b>METHODS</b>One hundred patients were randomized into an observation group and a control group, 50 cases in each one. In the control group, the basic treatment was applied, without other relevant rehabilitation therapies associated. In the observation group, with the basic treatment as the control group's, the therapy of the yin-yang meridians acupuncutre with respiratory reinforcing and reducing manipulation was adopted. On the yin meridians, Zuwuli (LR 10), Xuehai (SP 10), Yinlingquan (SP 9), Sanyinjiao (SP 6) and the others were selected and stimulated with reducing manipulation achieved by the coordination of patient's respiration. On the yang meridians, Biguan (ST 31), Liangqiu (ST 34), Yanglingquan (GB 34) and the others were selected and stimulated with reinforcing manipulation achieved by the coordination of patient's respiration. The treatment was given once a day and for 28 days totally. Before treatment and in 28 days of treatment, B-PHY balance function test training system was used to determine the weight shift track parameters (track length, peripheral square, track length of per unit square, left-right offset and rectangle square), the weight shift track distance parameters [mean of X axle weight shift distance (Mean-X), mean of Y axle weight shift distance (Mean-Y), maximum of X axle weight shift distance (Max-X), maximum of Y axle weight shift distance (Max-Y), weight shift distance (LSKG), weight shift square (SSKG), square ratio of weight shift (LFS)], stability coefficient (SI) and weight distribution coefficient (WDI).</p><p><b>RESULTS</b>After treatment, the differences in the weight shift track parameters, SI and WDI were significant as compared with those before treatment in the patients of the two groups (all P<0.01); while the differences in the weight shift distance parameters in the observation group were improved obviously after treatment as compared with those before treatment (all P<0.01), the differences of Mean-X, Max-Y and LFS in the control group were improved after treatment as compared with those before treatment (all P<0.01). Except SSKG, the improvements after treatment in the rest indices in the observation group were better than those in the control group (all P<0.05).</p><p><b>CONCLUSION</b>The yin-yang meridians acupuncture with respiratry reinforcing and re- ducing manipulation effectively improves the lower limbs balance function in the patients of stroke.</p>

Tetrandrine improves myocardial stunning in vitamin D3-induced calcium over load rats / 第二军医大学学报

Objective: To investigate the changes of myo cardial contractile function during myocardial stunning in calcium overload rats and the protective effects of tetrandrine. Methods: Forty-six rats were randomized into control, myocardial ischemia, myocardial stunning, low and high dose of tetrandrine groups. Another 10 rats were used to identify the calcium overload. vitamin D3 (0.3 million Unit/kg) and nicotinic acid were adm inistered. After 16 d when calcium overload occured, left anterior descending ar tery was ligated. Twenty minutes of myocardial ischemia followed by 60 min of re perfusion was induced. The contractile function parameters were determined dynam ically. At the end of experiment, myocardial cytosolic ［Ca2+］i was deter mined in various groups. In tetrandrine groups, tetrandrine (62.2 or 93.6 μmol/ kg ) was administered by gastrogavage daily.After 16 d, the rats undergone the e xperiments mentioned above. Results: Sixteen days after vitamin D3 , nicotinic acid were given, ［Ca2+］i increased by 2.6 folds (146.8±10.8 ) vs (368.5±22.6) nmol/L, (P<0.01). Whereas, ［Ca2+］i in tetrand rine groups were (210.8±16.4) and (198.6±15.3) nmol/L, which were significantl y lower than that of calcium overload group. Twenty minutes of myocardial ische mia resulted in the decrease of dp/dtmax and Vmax in all groups with the most si gnificant in stunning and calcium overload groups. The contractile function rest ored gradually after reperfusion. At all time points, dp/dtmax and Vmax in both tetrandrine groups were higher than those in both stunning and calcium overload groups. And effect with higher dose of tetrandrine were more significant than in low dose of tetrandrine. After 60 min of reperfusion, dp/dtmax in stunning, cal cium overload, low and high dose of tetrandrine groups were 49.7%, 51.5%, 71.0% and 83.4% of that in control, respectively， and Vmax were 55.0%, 49.8%, 73.9% and 77.5% of that in control, respectively. Conclusion: T he myocardial contractile function in vitamin D3-induced calcium overload gro up is impaired. On basis of myocardiocyte calcium overload, transient ischemia l eads to myocardial stunning. At the stage of ischemia, the impaired degree of my ocardial contractile function is similar to that in stunning group, suggesting a t this stage the effect of ischemia on myocardial function is greater than that of calcium overload. Tetrandrine chronically improves the myocardial function in Vitamin D3-induced calcium overload rats.
