Background Matrix metalloproteinases (MMPs) play important roles in the formation of choroidal neovascularization (CNV),but its mail origin is not ocular cells in situ.Bone marrow-derived cells (BMCs) participate in the formation of CNV and is probably a primary source of expressing MMPs in CNV.MMP-2/MMP-13 is speculated to be the regulating target genes of miR188-5p.Objective This study was to verify whether BMCs are the main source of MMPs,and whether the MMP-2/MMP-13 expression is potentially regulated by miR188-5p.Methods BMCs expressed green fluorescent protein (GFP) from transgenic female C57BL/6J mice were transplanted to female wild-type C57BL/6J mice to establish C57BL/6J.GFP chimeras models,and 42 mice with chimerisms more than 85% by flow cytometry were included as the experimental group.Other 42 wild-type C57BL/6J mice without the BMCs transplantation were enrolled as the control group.CNV was induced by laser coagulation of retinas on the mice of both groups.MMP-2/MMP-13 levels in the retinochoroid tissue were quantified by ELISA at day 1,3,5,7,10,14,and 28 after photocoagulation.The expression of miR188-5p mR NA in the retinochoroid tissue was assayed by real-time quantitative PCR (RT-qPCR).Immunofluorescence stain and fluorescent in situ hybridization were used to identify the MMP-2/MMP-13 and miR188-5p expressed by GFP-positive BMCs in CNV,and the expression level was quantified by images analysis.Results The proportion of GFP+ mouse mononuclear cells was (90.67±3.02) % in the C57BL/6J.GFP chimeras.The concentration changes of MMP-2/MMP-13 in retinochoroid homogenate showed a same tendency with the lapse of time between the experimental group and the control group (MMP-2:F=0.060,P =0.810 ; MMP-13:F =0.012,P =0.915).The expression level was zoomed in retinochoroid tissue after induce of CNV with the maximal value on the third day in both groups,and the proportion in the experimental group was 64.21% ;while the expression level of MMP-13 was slowly raised after induce of CNV with the peak at the seventh day,and the proportion in the experimental group was 79.61%.A complementary association point of miR188-5p was exhibited in the 3 '-untranslated regions of MMP-2 or MMP-13 by target gene prediction.The expression level of miR188-5p mRNA in the BMCs of CNV area was sharply declined after induce of CNV with the lowest value on the seventh day.A negative correlation was found between the expressing level of miR188-5p and MMP-13 protein (r=-0.868,P<0.05) as well as early stage of expression level of MMP-2 protein (r=-0.997,P< 0.05).Conclusions The elevation of MMP-2/MMP-13 expression levels is associated with the formation of CNV,and the regulation of miR188-5p expression in the BMCs of CNV area is responsible for increase of MMP-2/MMP-13 expression.The tendency of miR188-5p expression is inversed with MMP-2/MMP-13.

Objective To investigate the influences of Xuebijing injection on organs' ultra-microstructure in septic shock rats. Methods Fifteen male Sprague-Dawley (SD) rats of clean grade were selected. According to the method of random digits table, all of them were divided into three groups: sham operation group, model group and Xuebijing treated group, 5 rats being in each group. Cecal ligation and puncture (CLP) was adopted to reproduce abdominal cavity infection leading to sepsis model formation. While the rats in sham operation group just underwent abdominal median incision, abdominal exploration and closure of abdominal wall after flipping retrocecal region. In the Xuebijing treated group, within 1 hour after the operation, Xuebijing injection (4 mL/kg) was transfused through the catheter inserted in the femoral vein, and then normal saline (2 mL·kg-1·h-1) was continuously transfused until the rat being sacrificed. In the sham operation group and model group, equal volume of normal saline was given after operation. The blood pressure of all the rats was monitored continuously by a pressure device connected with a catheter inserted in the right carotid artery. The rats were observed for 12 hours, afterwards they were sacrificed, the samples of heart, lung, kidney and liver were taken, and their ultrastructural changes were observed under an electron microscope. Results The blood pressure of sham operation group was decreased a little with time extension, but within normal limits. The mean arterial pressure (MAP) of model group and Xuebijing treated group developed into a state of sepsis shock at 9 hours and 10 hours after operation respectively, and MAP were lower than 70 mmHg (1 mmHg=0.133 kPa). The MAP levels of model and Xuebijing groups at 11 hours after operation were lower significantly than those of sham operation group (mmHg:58.7±7.0, 58.7±8.3 vs. 91.0±8.2, both P<0.01), and they were persistently decreased at 12 hours after operation;the MAP in Xuebijing group was a little higher than that of model group at the same period (mmHg:55.4±4.0 vs. 48.8±12.9, P>0.05). The results of the observation with electron microscope:the structures of heart, lung, liver and kidney in sham operation group were basically normal;all the organs of model group appeared different degrees of structural damage. Compared with model group, the injury of heart and lung in Xuebijing treated group was milder, especially, the changes of cellular mitochondria were obvious;however, there was no significant difference in injury of kidney and liver between the model and Xuebijing treated groups. Conclusion Xuebijing injection can play a certain role in stabilizing the circulatory system in rats with septic shock, and can possibly ameliorate the heart and lung damage caused by infection and shock.
