Re-review showed 7 of the 13 cases were consistent with osteoporotic VCF healing in various stages with adjacent trilineage hematopoiesis.
再次读片发现13例中有7例在愈合不同阶段三系血细胞生成与骨质疏松VCF表现一致。

However, there is a catch: VCF has made the offer, but they are not going to improve it.
不过,我伦提供的这份合同不会再有任何改进,马蒂厄只能选择是接受还是拒绝。
