【摘要】AIM:To observe the alterations of hemorheology and coagulation system in members of marine corps after hyperthermia heavy training and field survival training and to provide theoretical basis for formulation of reasonable and scientific health and safeguard measurements. METHODS:One hundred and fifty one members of marine corps were observed among which 52 members participated in hyperthermia heavy training for 1 week,43 members participated in field survival training for 20 days and other 56 rear service members as control.Hemorheology and coagulation system related indexes before and after training were detected with coagulation analyzer and hemorheometer.
RESULTS:Compared with control,the hemorheological indexes:whole blood low shearing viscosity,whole blood middle shearing viscosity,whole blood high shearing viscosity,packed cell volume,erythrocyte sedimentation rate,whole blood low shearing reduction viscosity,whole blood middle shearing reduction viscosity,whole blood high shearing reduction viscosity,erythrocyte electrophoresis exponent was( 9.3± 0.5) mPa@
s,( 5.5± 0.3)mPa@ s,(4.5± 0.2)mPa@ s,( 48.5± 3.7)%,( 7.5±
1.5)mm/h,( 20.5± 4.1) mPa@ s,(10.2± 1.7) mPa@ s,( 7.8±
2.1) mPa@ s,6.0± 1.8,respectively (t=2.09-
3.61, P< 0.01).Sedimentation equation K
value,erythrocyte aggregation exponent,erythrocyte rigidity
exponent,erythrocyte degeneration exponent was 61.8± 12.5,2.6± 0.4, 5.3± 1.2,0.9± 0.1,respectively,there was a significant difference between two groups(t=2.09-2.92, P< 0.05).All these 13 items increased significantly.After field survival training whole blood low shearing viscosity,plasma viscosity was ( 8.8± 0.4),( 1.2± 0.1) mPa@ s(t=2.32,2.45, P< 0.05) .Erythroc yte sedimentation rate,erythrocyte electrophoresis exponent was ( 11.1± 1.8) mm/h, 6.3± 2.1(t=3.42,3.07, P< 0.01),which increased significantly.After hyperthermia heavy training, prothrombin time(PT),activated partial thromboplastin time(APTT)( 11.4± 0.2),( 27.7± 1.0) s (t=2.87, 3.08,P<
0.01),which decreased obviously.Fibrinogen(FIB),platelet(PLT) was ( 3.5± 0.3)g/L,( 265.6± 18.6)× 109/L, t=2.15,2.58, P< 0.05) ;Fibrin degradation product(FDP),D-dimer was ( 7.9± 0.4),( 335.9± 15.4) mg/L (t=3.22,2.91, P< 0.01),which increased significantly compared with control
group.However,after field survival training, PT( 12.4± 0.3) s(t=2.11, P<
0.05),APTT( 34.1± 4.6) s(t=2.97, P< 0.01) increased significantly. CONCLUSIONS:Coagulation function is enhanced after hyperthermia heavy training and hemorheological indexes indicate a higher blood viscosity,so prevention of thrombosis is necessary.Coagulation system indexes after field survival training indicate a low coagulation state and hemorrhage must be prevented.%目的探讨海军陆战队员在高温强训和野外生存训练后血液流变学和凝血系统的变化,为制定科学合理的卫生保障措施提供理论依据. 方法海军
陆战队员 151名,其中 52名参加为期 1周的高温强训, 43名参加野外生存训练 20 d, 56名为陆勤人员作为对照.使用凝血分析仪、血液流变仪检测高温强训前、高温强训后、野外生存训练后的血液流变学和凝血系统相关指标. 结果高温强训后,血液流变学指标:全血低切黏度、全血中切黏度、全血高切黏度、红细胞压积、红细胞
沉降率、全血低切还原黏度、全血中切还原黏度、全血高切还原黏度、红细胞电泳指数分别为( 9.3±0.5),( 5.5± 0.3),( 4.5± 0.2) mPa@ s,( 48.5± 3.7)%,( 7.5± 1.5) mm/h,( 20.5± 4.1),( 10.2± 1.7),( 7.8± 2.1) mPa@ s,6.0± 1.8,与对照组比较,差
异有显著性意义 (t=2.09～ 3.61,P< 0.01).血沉方程 K值、红细胞聚集指数、红细胞刚性指数、红细胞变性指数分别为61.8± 12.5, 2.6± 0.4, 5.3± 1.2, 0.9± 0.1均比对照组显著增高 (t=2.09～ 2.92, P< 0.05).野外生存训练后全血低切黏度、血浆黏度分别为( 8.8± 0.4),( 1.2± 0.1) mPa@ s(t=2.32,2.45,P< 0.05) ;红细胞沉降率、红细胞电泳指数分别为11.1± 1.8, 6.3± 2.1,此 4项均较对照组有显著升高
(t=3.42,3.07, P< 0.01).高温强训后凝血酶原时间 (prothrombin time, PT)、部分凝血酶原时间 (activated partial thromboplastin time, APTT)分别为( 11.4±
0.2),( 27.7± 1.0) s,均较对照组显著下降 (t=2.87,3.08, P< 0.01);纤维蛋白原(Fibrinogen, FIB)、血小板 (platelet, PLT)分别为( 3.5± 0.3)g/L, (265.6± 18.6)× 109/L(t=2.15,P< 0.05);血清纤维蛋白降解产物 (Fibrin degradation product, FDP)、D-二聚体分别为( 7.9± 0.4), (335.9± 15.4) mg/L,此 4项与对照组相比有
显著升高 (t=2.91, P< 0.01).而野外生存训练后, PT, APTT分别为( 12.4±
0.3),(34.1± 4.6) s(t=2.11, P< 0.05, t=2.97, P< 0.01),较对照组有非常显著升高.
结论高温强训后凝血功能加强,血液流变学指标显示高黏发生,需防止血栓形成.野外生存训练后凝血系统指标提示血液低凝状态,需防治出血的发生.
