According to random number table,they were divided into a treatment group(29 cases) and a control group(28 cases). In the treatment group, the fuzhengbutu acupuncture-moxibustion therapy combined with rehabilitation treatment was adopted. In the control group, the rehabilitation treatment was given. The persistent walking time and pause time in PIERENSTEP gait measurable training and test system as well as the score of Berg balance scale(BBS) were compared between the two groups.Results: In the treatment group, the persistent walking time after treatment 1.47 ±0.28) s was shorter obviously versus before treatment(2.12 ± 0.38)s, indicating the significant difference(P<0.05). The pause time after treatment was not different obviously versus before treatment(P> 0.05). In the control group,the persistent walking time after treatment(1.88 ± 0.22) s was shorter obviously versus before treatment(2.18 ± 0.30)s, indicating the significant difference(P<0.05). The pause time after treatment was not different obviously versus before treatment(P> 0.05). Before treatment, the differences were not significant in the persistent walking time and pause duration in the patients of either group(P>0.05). After treatment, the persistent walking time in the treatment group was shorter obviously than the control group(P<0.05) and the difference in pause time was not significant between the two groups(P>0.05). Before treatment, there was no difference in BBS score between the two groups(P>0.05). In the treatment group, BBS score(42.79 ±2.78) after treatment was higher than(35.86 ±2.64) before treatment, indicating the significant difference(P<0.05). In the control group, BBS score(39.07 ±2.67) after treatment was higher than(35.86 ±2.64) before treatment, indicating the significant difference(P<0.05). In comparison of BBS score after treatment between the two groups, the score in the treatment group was higher than the control group, indicating the significant difference(P<0.05).Conclusion: Based on rehabilitation treatment, Fuzhengbutu acupuncture-moxibustion therapy effectively improves the walking function of the patients with hemiplegia after ischemic stroke.展开更多

The saline water was used as a blank control, and 1% hydrochloric acid of methamphetamine Massachusetts was used as the negative control. Compared with normal saline control, the relative percentage of the lasting time of ciliary movement treated with Chinese medicine Xingbi was 94.1%. There was no remarkable pathological change in the tissue slice of nasal mucosa, and no stimulation on nasal mucous membrane was observed. So these data suggest that nasal thermosensible gel of Chinese medicine Xingbi is of high safety. It has no damage to the mucosa of toads and rats and can be used for intranasal administration.展开更多
