BACKGROUND:Establishment of in vitro culture system of human placental microvascular endothelial cel s with high purity is very important. In recent studies, some scholars have successful y obtained a large number of placental microvascular endothelial cel s by three-stepenzyme digestion and magnetic separation method, but the procedures were extremely complex and it had great damage to the cel s. Therefore, how to separate human placental microvascular endothelial cel s easily and obtain high-purified cel s has become a research hotspot.
OBJECTIVE:To investigate an efficient method to isolate and purify human placental microvascular endothelial cel s from early vil us microvessels, observe the cel growth and identify the cel s.
METHODS:The vil i from normal early pregnancies (6-8 weeks) after artificial abortion were col ected aseptical y. Using two-step digestion procedure and discontinuous Percol density gradient centrifugation method, human placental microvascular endothelial cel s were obtained. Then the cel s were identified by trypsin digestion method and repeated adherence method.
RESULTS AND CONCLUSION:Human placental microvascular endothelial cel s were isolated successful y from early vil i. The primary cel s adhered to the wal s after inoculated for 24 hours and entered logarithmic phase at 10 days. 80%of the cel s achieved a confluence at 12-13 days after inoculating. The subculture cel s grew swiftly with the typical cobblestone appearance. Immunofluorescence staining showed that, cultured human placental microvascular endothelial cel s demonstrated a strong positive reaction to von Wil ebrand factor antigen and CD31, accounting for 100%. MTT assay results showed that, human placental microvascular endothelial cel s at passage 5 exhibited an S-shaped growth curve. High-purity human placental microvascular endothelial cel s can be obtained by proteolytic enzymes digestion and discontinuous Percol density gradient centrifugation method, and the purity is detected by trypsin digestion method and repeated adherence method.

Objective To prospectively study the difference of urinary N-acetyl-β-D-glucosaminidase( UN-AG) and retinol binding protein(URBP) in contrast-induced nephropathy (CIN). Methods The clinical data of 150 patients undergoing coronary angiography were documented. The urine and blood samples before,24 hours after and 48～72 hours after the procedure were collected;Serum creatinine (SCr) and urinary ereatinine (UCr)were tested by enzymic method. UNAG and URBP were tested by ELISA in CIN and control group. CIN was defined as an increase in SCr of ≥44 μmol/L or >25% from baseline 48 ～72 h after the procedure. 27 age- , sex- , results of coro-nary angiography-matched cases were taken as control group. Results CIN was diagnosed in 13 of 150 patients (8.7%). In CIN group, UNAG/UCr were significantly higher than that in control group[ 1.97 (1.06,2.64) U/mmol vs 1.07 (0, 68,1.88 ) U/mmol, Z = 2.076, P = 0.039 ] before ;24 hours after the procedure, UNAG/UCr was signifi-cantly up-regulated in CIN group from baseline level [ 2.82 ( 1.88 ,4.26) U/mmol vs 1.97 (1.06,2.64) U/mmol, Z =2.607,P =0. 009]. ROC curve analysis showed that baseline UNAG could be used as an early predictor for CIN, the AUC =0. 776 ,P =0.023 ;when cut off value = 8.08 U/L,the sensitivity and specificity of UNAG were 0. 771 and 0. 713 respectively. The percentage of patients of UNAG over 8.08 U/L in CIN group was significantly higher than that in control group[77.1% (10/13) vs 29.6% (8/27) ,Z =2. 564,P =0. 011 ] ,the related risk factor is 5.58,95% CI was 1.24 ～ 25.08. Conclusion UNAG could be used as a predictor of CIN before the procedure and its postprocedure 24 h level maybe useful in early diagnosis after the procedure.
