ABSTRACT
Up to now, a variety of microRNAs have been found in a number of studies, that specifically expressed in retinal neuroepithelial, lens, cornea and retinal pigment epithelium, in which miR-126 plays a certain role in the proliferation of tumor cells, the development of thymus lymphocytes and cardiovascular diseases.Some researches show that miR-126 has certain correlations with the formation of corneal neovascularization, the development of diabetic retinopathy, and the immune system related eye disease.In this paper, the current miR-126 in the role of eye disease mechanism and research progress were reviewed.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the changes of physiological activities and functions in vitro of apheresis platelets during storage.</p><p><b>METHOD</b>17 units of apheresis platelets were randomly chosen and stored at 20 °C to 24 °C with agitation. Platelet counting (Plt), mean platelet volume (MPV), blood gases, pH value, glucose (Glu) concentration, lactate (LA) concentration, LDH concentration, thromboelastogram (TEG), hypotonic shock response (HSR), CD62p expression rate and anew expression rate were measured on days 0, 1, 3, 5 after platelet storage. Changes of physiological activities and functions in vitro were systematically evaluated by above-mentioned indexes.</p><p><b>RESULTS</b>During storage, Plt, MPV and HSR were not significantly changed; but pH value, blood gases, Glu, LA, LDH, HSR, expression rate of CD62p and anew expression rate were significant differenty. Among thromboelastogram indexes, R value increased obviously with prolongation of storage time; K value and αAngle were not significantly changed; MA was not significantly changed on day 1 and 3, but was slightly increase on day 5.</p><p><b>CONCLUSION</b>The physiological activities and functions in vitro of apheresis platelets are kept well during storage. For clinical transfusion of apheresis platelet during storage, clinical effect of transfusione is not influenced.</p>
