断指再植患者血浆血管性血友病因子和P选择素动态监测的临床意义

目的 通过对断指再植患者血浆中血管性血友病因子(VWF)与P选择素(GMP-140)水平变化的动态观察,探讨断指再植术患者血液出现高凝状态与再植成活率的关系.方法 选择2004年12月至2006年12月断指再植患者80例(再植组),采用定量ELISA法测定再植组患者术前、术后的VWF与P选择素水平,并与健康对照组比较;观察再植组术后2个指标的动态变化;比较同一观察时间点再植成活组与失败组间VWF与P选择素水平.结果 再植组与健康对照组间VWF水平差异有统计学意义(F=14.76,P<0.01);再植组血浆VWF水平在术后1、4、8、16 h分别为(1 715±493)、(1 396±549)、(1 266±504)、(1 163±436)U/L,与健康对照组(903±187)U/L比较,差异有统计学意义(P<0.01);再植组与健康对照组间P选择素水平差异有统计学意义(F=11.76,P<0.01);再植组血浆P选择素水平在术后1、4、8、16、24 h分别为(14.7±2.6)、(12.5±3.0)、(11.8±3.2)、(11.1±3.0)、(10.5±2.6)μg/L,与健康对照组(9.1±1.2)μg/L比较,差异有统计学意义(P<0.01).再植成活组VWF水平在术前、术后1、4、8、16、24、48、72 h分别为(854±209)、(1 535±389)、(1 177±407)、(1 040±283)、(958±216)、(829±193)、(777±151)、(713±137)U/L;再植失败组分别为(1 202±164)、(2 333±243)、(2 146±161)、(2 039±244)、(1 865±170)、(1 645±283)、(1 427±331)、(1 188±262)U/L,同一时间点组间比较,差异有统计学意义(t值分别为4.44、5.12、6.10、8.43、10.17、8.85、5.10、4.61,P均<0.05);再植成活组P选择素水平在术后1、4、8、16、24、48、72 h分别为(13.9±2.5)、(11.2±2.0)、(10.2±1.6)、(9.6±1.2)、(9.2±0.9)、(9.5±0.6)、(9.3±0.4)μg/L;再植失败组分别为(17.2±1.0)、(16.9±1.0)、(17.0±1.3)、(16.1±1.1)、(14.9±1.5)、(13.8±1.4)、(12.8±1.2)μg/L;同一时间点组间比较,差异有统计学意义(t值分别为5.22、9.91、10.35、12.79、9.46、9.45、9.33,P均<0.01);术后不同时间段VWF、P选择素有动态变化,在术后1～4 h升高明显,持续至24、48 h后逐渐恢复至术前水平.结论断指再植术后血液呈高凝状态与VWF与P选择素水平有关.动态监测两者水平对判断血液出现高凝状态和抗凝治疗有一定的指导意义.

The dynamic changes of plasma yon willebrand factor and P-selectin in the finger replanted patients and their clinical significance

Objective To explore the dynamic changes of von willebrand factor(VWF)and Pseleetin in the finger-replanted patients,and the relationship between the prognosis of the surgery and hypercoagulability.Methods From December 2004 to December 2006,eishty finger-replanted patients were recruited to our study.with 40 healthy volunteers as controls.Plasma VWF and P-selectin were detected by enzyme-linked immunosorbent assay(EUSA)in both controls and patients before or after replantation.Results The VWF and P-selectin levels had significant differences between the replantations and controls(F=14.76,11.76,P＜0.01).The VWF levels in the patients of 1,4,8,16 hours after replantation were(1 715±493),(1 396±549),(1 266±504),(1 163±436)U/L respectively,all markedly higher than the controls(P＜0.01).The P-selectin levels in patients of 1,4,8,16,24 hours after operation were(14.7±2.6),(12.5±3.0),(11.8±3.2),(11.1±3.0)、(10.5±2.6)μg/L,significanfly higher than the controls(P＜0.01).The VWF levels in patients of pre-replantion and the 1,4,8,16,24,48,72 hours after replantation were(854±209),(1 535±389),(1 177±407),(1 040±283),(958±216),(829±193),(777±151),(713±137)U/L in successful group,and were(1 202±164),(2 333±243),(2 146±161),(2 039±244),(1 865±170),(1 645±283),(1 427±331),(1 188±262)U/L in unsuccessful groups.They were all significantly different at the same test-time points between two groups(t=4.44,5.12,6.10,8.43,10.17,8.85,5.10.4.61,P＜0.05).The P-selectin levels in patients of 1,4,8,16,24,48,72 hours after replantation were(13.9±2.5),(11.2±2.0),(10.2±1.6),(9.6±1.2),(9.2±0.9),(9.5±0.6),(9.3±0.4)μg/L in successful group,and(17.2±1.0),(16.9±1.0),(17.0±1.3),(16.1±1.1),(14.9±1.5),(13.8±1.4),(12.8±1.2)μg/L in unsuccessful group.Significant difference existed at the same testtime points between two groups again(t=5.22.9.91,10.35,12.79,9.46.9.45,9.33,P＜0.01).After replantation,both VWF and P-selectin were rapidly elevated and went to the summit 4 hours later,then declined to pre-replantation level about 24 to 48 hours later after replantation.Conclusions VWF and P-selectin were associated with the hypercoagulability.Dynamic monitoring VWF and p-selectin may be useful in determining the existence of hypercoagulability and the therapy of anti-coagulability.
