Amblyopia greatly affects the physical and mental development of children. Acupuncture is effective for amblyopia, though its mechanism remains unclear. This article summarized the mechanism of acupuncture treatment of amblyopia from the perspectives of morphology of neurons in visual cortex, visual electrophysiology, and molecular biology, etc. It was found that acupuncture may treat amblyopia through repairing the morphological and ultrastructural damages of neurons in visual cortex, promoting the electrical activities in visual pathway and visual cortical neurons, and modulating the synthesis and expression levels of factors involved in visual system. Nevertheless, further studies are required to unveil the mechanism of acupuncture treatment of amblyopia.

Objectiye To optimize the depth of the microchannel and the time point for sperm collection,and improve the efficiency of sperm screening on a microfluidic device. Methods Microchannels with four different depths of 25, 50, 100 and 200 μm were tested. Mice sperm were added to the inlet of the microchannel. The relative quantity and motility of sperm in the outlet were recorded at different collection times, i.e. ,5, 15, 30 and 60 min. Statistical method one-way ANOVA and appropriate post-hoc testing were applied to analyze differences between different groups, and further to select the best-fit depth of the microchannel and the time point for collection. Results In microchannels with depths of 25, 50, 100 and 200 μm, the sperm motilities measured in each outlet were (85.4 ± 2.3)%, (85.8 ± 5.8)%,( 87. 2 ± 2. 8 ) %, (76. 5 ± 2. 8 ) % respectively with statistical significance ( F = 5.8, P ＜ 0. 05 ). No obvious differences were found among 25-100 μm channels, however the motility dramatically decreased in the 200 μm group. The relative sperm quantities were (5.2 ±2.0)%, (7.2 ±2.5)%,(12.3 ±2.0)%,(7. 7 ± 1.1 ) % respectively with statistical significance ( F = 6. 9, P ＜ 0. 05), which increased with channel depth from 25 to 100 μm,while it decreased in the 200 μm channel Taking 2 indexes into account, 100 μmwas the most fit channel depth for sperm motility screening. The sperm motility in the outlet gradually decreased with time. At the time points of 5, 15, 30 and 60 min after adding sperm, the sperm motilities were (99. 6 ±0. 7)%, (87.2 ±2. 8)%, (79. 3 ±2. 2)% and (62. 6 ±8.0)% respectively with statistical significance ( F = 37. 3, P ＜ 0. 01 ). Yet the relative quantities of sperm in the outlet increased almost three times in this process. At the time points mentioned above, the relative quantities of sperm were (5.8±1.1)%, (10.6 ± 0.9)%, (12.1 ± 1.7)%, (17.9 ± 3.4)% respectively with statistical significance ( F = 17.8, P ＜ 0. 01 ). Thus 15-30 min was the ideal screening time. Conclusion An effective microdevice for sperm screening with optimized depth and collection time period is developed,which may contribute significantly for the screening of healthy sperm on microfluidic chips.

BACKGROUND:The production and release of a large amount of inflammatory factors caused by immune system inflammatory response mainly contributes to secondary spinal cord injury. OBJECTIVE:To investigate the effects of umbilical cord Wharton’s jely mesenchymal stem cel transplantation on repair of injured neurological function and expression of inflammatory factors monocyte chemoattractant protein 1 and interleukin 10 in rats with acute spinal cord injury. METHODS: Eighty-one healthy adult male Sprague-Dawley rats were randomly and equaly divided into sham operation, model and cel transplantation groups, with 27 rats per group. Rats in the latter two groups were subjected to hemisection of the spinal cord to establish acute spinal cord injury models. Rat models in the cel transplantation group received umbilical cord Wharton’s jely mesenchymal stem cel injection (1×106)via the tail vein. Rat neurological function was evaluated using the BBB score at different time points after spinal cord injury. The expression of monocyte chemoattractant protein 1 and interleukin 10 in injured spinal cord tissue was detected using ELISA assay at different time points after spinal cord injury. Migration and neuronal differentiation of umbilical cord Wharton’s jely mesenchymal stem cels in the injured spinal cord tissue were determined using immunohistochemical staining method. RESULTS AND CONCLUSION:Compared with the sham operation and model groups, rat neurological function was significantly recovered in the cel transplantation group (P < 0.05). Compared to the model group, monocyte chemoattractant protein 1 level in the serum and monocyte chemoattractant protein 1 mRNA and protein expression in the injured spinal cord tissue were significantly lower (P < 0.05), but interleukin 10 mRNA and protein expression in the injured spinal cord tissue was significantly higher (P < 0.05), in the cel transplantation group. In the cel transplantation group, umbilical cord Wharton’s jely mesenchymal stem cels could migrate to the injured region and express glial fibrilary acidic protein. These findings suggest that umbilical cord Wharton’s jely mesenchymal stem cels promote rat neurological function recovery by regulating the inflammatory response in the injured spinal cord tissue, which is likely to be one of mechanisms by which transplantation of umbilical cord Wharton’s jely mesenchymal stem cels treats spinal cord injury.
