【摘要】：目的分析健康中老年凝血酶原时间与地理环境的关系,为制定健康中老年凝血酶原时间参考值提供科学依据。方法搜集全国83个单位12 316例健康中老年凝血酶原时间参考值,运用相关分析将健康中老年凝血酶原时间参考值与选取的16项地理因素指标进行了研究,提取其中存在相关性的8项地理因素进行主成分分析,建立回归模型。运用Arcgis10.0,采用克里金法进行插值并输出健康中老年凝血酶原时间参考值的地理分布图。结果用主成分分析法建立回归模型,y=15.75-0.017 6X1+0.000 171X_3-0.007 15X_8-0.173X_9-0.002 94X_(10)+0.003 06X_(11)-0.659X_(14)+0.099 7X_(16)±0.075 2。中国健康中老年人凝血酶原时间参考值总体呈现从东往西逐渐升高的分布规律。结论已知中国某地地理因素,经度(X_1)、海拔(X_3)、气温年较差(X_8)、年平均风速(X_9)、表土砂砾百分率(X_(10))、表土粉粒百分率(X_(11))、表土容重(X_(14))、表土有机质含量(X_(16)),可通过此模型估算该地健康中老年凝血酶原时间参考值。
[Abstract]:Objective to analyze the relationship between prothrombin time and geographical environment in healthy middle-aged and old people. Methods the prothrombin time reference values of 12 316 healthy middle-aged and old people in 83 units of China were collected. Correlation analysis was used to study the reference value of prothrombin time and 16 geographical factors selected in the healthy middle and old age, and 8 of them were extracted for principal component analysis. The regression model was established. Arcgis 10.0 was used to interpolate and output the geographical distribution of the reference value of prothrombin time. Results the regression model was established by principal component analysis.

Conclusion the geographical factors of some place in China are known. The annual average annual wind speed is X 9 / T, the topsoil sand gravel percentage is 10 / 10 / and the topsoil silt percentage is 1 / 11). The surface soil bulk density and the organic matter content of the topsoil are X _ S _ (16), which can be used to estimate the reference value of the prothrombin time of the healthy middle-aged and old people in this area.

【正文快照】： 凝血酶原时间是指在缺乏血小板的血浆中加入过量的组织因子(兔脑渗出液)后,凝血酶原转化为凝血酶,从而导致血浆凝固所需的时间其正常值为12~14 s。凝血酶原时间是临床常用的测定外源性凝血因子的过筛实验,具有敏感、快速的优点,广泛用于多种疾病的诊断和治疗〔1〕。该试验用于
