目的以术后肝功能不全程度为标准来研究术前吲哚氰绿15 min内滞留率(indocyanine green retention rate at 15 minute,ICG-R15)、综合的终末期肝病模型评分(the integrated model for end-stage liver disease scores,i MELD)和慢性肝...目的以术后肝功能不全程度为标准来研究术前吲哚氰绿15 min内滞留率(indocyanine green retention rate at 15 minute,ICG-R15)、综合的终末期肝病模型评分(the integrated model for end-stage liver disease scores,i MELD)和慢性肝功能不全评分(chronic liver dysfunction scores,CLD)三者之间的相关性。方法回顾性分析61例行手术切除的原发性肝细胞肝癌患者的临床资料,根据肝功能不全程度分为轻、中、重三组,利用脉冲式色素浓度分析法(pulse dyedensitonmetry,PDD)行吲哚氰绿(indocyanine green,ICG)排泄试验,同时计算患者的i MELD及CLD评分。结果随着术后肝功能不全程度的递增,ICG-R15及CLD评分逐渐升高,差异具有统计学意义(P<0.05);ICG-R15与CLD评分相关性明显强于ICG-R15与i MELD评分的相关性(r=0.65,r=0.49)。结论 ICG-R15与CLD评分正向相关性明显强于i MELD评分。展开更多

FBRM (Focused Beam Reflectance Measurement) can measure CLD (Chord Length Distribution) in line, but CLD is different from CSD because of principle of FBRM.

First, when crystal shape is defined from the characteristic crystal size, the matrix of each crystal shape which transforms CSD into CLD in a uniform manner is calculated with Monte Carlo analysis. Characteristic crystal size is added to the variables defining chord length in order to avoid complex integrals and apply the change in crystal shape with characteristic crystal size to the transforming matrix.
