Chinese Journal of Obstetrics and Gynecology 2001;36(4):206-208
Objective To investigate the changes and its clinical significance of plasma neuropeptide Y(NPY) concentration in patients with pregnancy induced hypertension (PIH). Methods Plasma NPY levels were detected by radioimmunoassay in 30 patients with PIH, 20 normal non-pregnant women and 23 normal pregnant women. The PIH group was subdivided into mild, moderate and Severe subgroups, and the NPY concentration was also measured in these subgroups respectively at admission and one week after delivery. Results The plasma NPY levels in patients with PIH [(164.16±68.32) ng/L] were significantly higher than those of normal non-pregnant women and normal pregnancies [(86.60±20.65) ng/L, (82.42±12.46) ng/L, P<0.01, respectively]. There was significant difference among plasma NPY levels among the patients with mild, moderate, and severe PIH at admission (P<0,01). At one week after delivery the concentrations of plasma NPY were significantly decreased in the moderate and severe subgroups compared with the value measured at admission (P<0.01). Moreover, the NPY levels in patients with severe PIH after delivery were still higher than those of normal non-pregnant women. Conclusions The results suggested that the level of NPY in plasma is increased in women with PIH. Elevated plasma NPY levels may play a key role in the development of PIH.

BACKGROUND:Mesenchymal stem cels isolated from cord blood and bone marrow have multi-directional differentiation ability under a certain condition of induction. OBJECTIVE:To compare the difference of differentiation of umbilical cord blood and bone marrow mesenchymal stem cels into osteoblasts. METHODS:Human umbilical cord blood and bone marrow mesenchymal stem cels were isolated and cultured by density gradient method. When reached 90% confluency, mesenchymal stem cels were digested by trypsin for subculture. At the third passage, umbilical cord blood mesenchymal stem cels and bone marrow mesenchymal stem cels at 8×104/wel were incubated. When reached 80% confluency, cels were treated with low-glucose DMEM supplemented with 10% fetal bovine serum, 0.1 μmol/L dexamethasone, 50 μmol/L vitamin C and 10 mmol/L β-sodium glycerophosphate. RESULTS AND CONCLUSION:There was no significant difference in morphology and biological properties of the two kinds of mesenchymal stem cels. Cels were highly expressed CD44, CD29, but did not express CD34. They had the ability to differentiate into osteoblasts, which had a positive staining for known markers: alkaline phospatase and calciumin vitro mineralization. There was no significant difference in the activity of osteoblasts of two kinds of cels. Results verify that umbilical cord blood and adult bone marrow mesenchymal stem cels can be induced into osteoblasts with a similar ability, and they can be used as seed cels for bone tissue engineering.
