ABSTRACT
Aim To investigate the effect of methyl salicylate lactoside (MSL) on the spatial memory and learning of Alzheimer' s disease mice. Methods APP/PS1 double transgenic mice were used as AD animal model to evaluate behavioral changes by Morris water test. At the end of the experiment the brain tissues were fixed for assessment of A(3 deposition by immunohistochemistry, neuronal function changes by Nissl staining, neuronal morphological changes by transmission electron microscopy. Results The results showed that MSL could improve the spatial learning and memory abilitiesof AD mice by shortening latency time, prolonging time spent in target quadrant and increasing number of crossings of APP/PS1 mice. MSL could reduce partial Aβ deposition, alleviate the damage of nerve cells and improve the ultrastructural lesions of neuropil projections. Conclusion MSL could reduce Aβ deposition and protect neurons through anti-inflammatory effects, thus improving the learning and memory abilities of Alzheimer' s APP/PS1 transgenic mice.
ABSTRACT
The clinical efficacy of acupuncture and moxibustion for post-stroke constipation was systematically reviewed. By computerized and manual retrieval of clinical research literature regarding acupuncture and moxibustion for post-stroke constipation, the randomized control trials (RCTs) that met the inclusive criteria were collected. Cochrane systematic review method was used and Revmen 5.2 software was adopted to perform this Meta analysis. Totally 8 articles were included, involving 610 cases of post-stroke constipation. As a result, the total effective rate and cured rate of acupuncture and moxibustion for post-stroke constipation were significantly superior to those of the control group [total effective rate: OR = 2.10, 95% CI (1.25, 3.54), Z = 2.78, P = 0.005; cured rate: OR = 2.37, 95% CI (1.57, 3.58), Z = 4.10, P < 0.0001]. This result indicated that acupuncture was effective for post-stroke constipation and had some advantages compared with other therapies. But the quality of included RCTs was low, and high-quality, large-sample and multi-center RCTs were needed to perform further verification.
