弱视是由于视觉发育关键期内各种异常的视觉经验导致单眼或双眼最佳矫正远视力低于正常同龄儿童,而眼部无明显器质性病变。目前普遍观点认为,弱视的发病机理主要源于视皮层。近年来,光学相干断层扫描（OCT）作为一种先进的活体成像技术,促进了对视网膜形态结构的大量研究,同时也被应用到弱视的研究领域。陆续有不同的研究人员利用OCT发现弱视患者眼底视网膜、脉络膜等眼部结构存在改变。笔者将对弱视眼底OCT的研究进展做一综述。 相似文献

BACKGROUND: There is no effective treatment for muscle atrophy caused by peripheral nerve damage. Skeletal muscle cells, a structural unit of muscle contraction, can be used for studies on muscle atrophy when cultured in vitro.
OBJECTIVE: To investigate the promotion effect of neuron-secreted factors on the growth of skeletal muscle cells in vitro.
METHODS: Skeletal muscle cells primary cultured in vitro were divided into two groups: experimental group with neuron-secreted factors, and control group with common culture medium, respectively. Afterwards, the number of skeletal muscle cells and expression level of alpha actin were detected by hematoxylin-eosin staining and immunohistochemical staining, respectively.
RESULTS AND CONCLUSION:The number of skeletal muscle cells and expression level of alpha actin in the experimental group were significantly higher than those in the control group (P < 0.05). In conclusion, neuron-secreted factors have the ability of promoting the growth of skeletal muscle cells and may be helpful for denervated muscle atrophy.
