Carbon nanotube forest (CNTFs) is grown vertically on the surface of highly conductive mesophase pitch carbon fibers (Pitch‐CFs) in the chemical vapor deposition method. Then the CNTFs‐modified CFs (CNTFs‐Pitch‐CF) as an anode material is assembled into the single chamber microbial fuel cells (MFCs). Interaction between electricigens and carbon nanotubes (CNTs) is investigated. The toxicity of the CNTs can make electricigens expend energy or electrons to produce exopolysaccharid (EPS) as much as possible. Accordingly, this leads to low voltage and the long start up time for the CNTFs‐Pitch‐CF anode in the early period. When the activity of electricigens with the EPS reaches a stable state over time, the output voltage rises rapidly and the maximum power density of the CNTFs‐Pitch‐CF‐equiped MFC is increased to 1112 mW/m2, which is approximately 1.55‐fold higher than Pitch‐CF‐equiped MFC. And the CNTFs‐Pitch‐CF‐equiped MFC can keep high electricity generation performance of MFCs for a long time, which is 75 % larger than the Pitch‐CF‐equiped MFC. This method of the CNTFs modifying the CFs provides a new idea for increasing the electricity generation performance of the MFCs. Mechanism analysis The schematic is used to explain the interaction between the carbon nanotubes(CNTs) and electricigens. CNTs can stimulate the epidermis of elctricigens and cause biological response, making electricigens expend energy or electrons to produce exopolysaccharid (EPS). When EPS is sufficient to counteract the stimulation or toxicity of CNTs, the rough surface and forest structure of CNTs modified anode can greatly decrease the internal resistance and promote the extracellular electron transfer.

Objective: To explore the cell population data (CPD) parameters of DxH800 hematology analyzer in predicting engraftment after hematopoietic stem cell transplantation., Methods: Data from 109 patients who underwent hematopoietic stem cell transplantation at Peking University First Hospital between July 2013 and September 2014 were selected, all CBC data including CPD parameters from the beginning to engraftment (absolute neutrophil count > 500/µl) were gathered and analyzed to find the early markers of myeloid engraftment and establish the cut-off value., Results: The makers which could predict myeloid engraftment were mean neutrophil volume (MNV) and mean monocyte volume (MMV), the cut-off value was ≥ 180 fl and ≥ 190 fl, respectively, and engraftment was predicted earlier (2.2 ± 1.3) days and (2.3 ± 1.7) days than absolute neutrophil count., Conclusion: By analyzing the CPD data of DxH800 hematology analyzer, engraftment can be predicted approximately 2 days earlier than absolute neutrophil count.
