Uremia caused secondary hyperparathyroidism is one of the common and serious complications caused by uremia. Surgery treatment is effective. Total parathyroidectomy plus forearm transplantation is more commonly used because of exact outcomes and easy monitoring. It is necessary to be fully prepared be-fore operation,particularly to clarify the location of parathyroid gland. Yet each surgical method has its re-lapse rate.

BACKGROUND:Currently, there is no uniform, standardized approach to isolate, purify and proliferate bone marrow mesenchymal stem cells. Chlormethylbenzamido-1,1'-dioctadecyl-3,3,3',3'-tetramethylindocarbocyanine (CM-Dil) is a stable, reliable, high marking and simple marker.
OBJECTIVE:To develop the methods for isolation, culture and identification of rat bone marrow mesenchymal stem cells in vitro.
METHODS:Two male Sprague-Dawley rats, weighing 50-100 g were taken to col ect the bilateral femur and tibia bone marrow under sterile conditions, and then, primary bone marrow mesenchymal stem cells were isolated and cultured using bone marrow adherent separation and density gradient centrifugation. cells were amplified and purified through timely and repeated passage, and labeled at the third generation with fluorescent dyes CM-Dil in vitro as a source of donor cells.
RESULTS AND CONCLUSION:Bone marrow mesenchymal stem cells were cultured successful y in vitro using bone marrow adherent separation and density gradient centrifugation separation methods, but the former was superior to the latter in the number of cultured cells significantly, while the two methods were not different significantly in terms of cellviability and proliferation. Flow cytometry results showed that the positive rates of cultured cells were 17.5%for CD34, 97.9%for CD44, and 91%for CD90. CM-Dil can label bone marrow mesenchymal stem cells successful y, which is a stable, reliable, high marking and simple marker.

Objective To observe the effects of ACEI( enalapril) on expression of MMP-2 and MMP-9 in renal hypertension rats with focal cerebral ischemia-reperfusion injury. Methods Twenty-eight Wistar male rats were randomly divided into two groups: hypertension group and normaltension group. The former which formed model of renal hypertension rats by constricted renovascular were randomly divided into enalapril group (Y) and hypertension ischemia and reperfusion group(HIR),which fed with enalapril 2mg/kg and equal volum saline respectively;The latter were divided into sham-operation group ( N) and normaltension ischemia and reperfusion group (IR). The focal cerebral ischemia model was established in Wistar rats by using the method of thread inserting left middle cerebral artery occlusion(MCAO) for 2h. After ischemic 24h,the expression of MMP-2 and MMP-9 were measured by immunohisto-chemistry,and the gray scale value was measured by imaging analysis. Results Compared with N,the gray scale values of MMP-2 and MMP-9 in IR were higher(P <0. 01); Compared with IR, the gray scale values of MMP-2 and MMP-9 in HIR were higher(P<0. 05);Compared with HIR,the gray scale values of MMP-2 and MMP-9 in Y were lower(P<0.01). Conclusion Hypertension can increase the expression of MMP-2 and MMP-9 in rats with focal cerebral ischemia-reperfusion. ACEI (Enalapril) could inhibit the expression of MMP-2 and MMP-9 in renal hypertension rats with focal cerebral ischemia-reperfusion.
