Otherwise, the number of hematopoietic stem cells and erythroid progenitor cells were increased in the bone marrow, and monocytes were decreased in the PTS and PDS group (CD34+: 2.22 ± 0.32% in the model group vs. 4.42 ± 1.11% in the PTS group, P < 0.05; CD71+/Ter119+: 0.17 ± 0.10% in the model group vs. 0.33 ± 0.30% in PDS, P > 0.05; and CD11b+/Gr-1+: 3.75 ± 3.19% in the model group vs. 72.04 ± 7.13%, 77.53 ± 5.18%, 75.20 ± 5.86% in the PDS, PTS, and PNS group, P < 0.05). Here, CD34 is linked to paraneoplastic neurologic syndrome.
