In this work, the membrane surface of poly（acrylonitrile-co-2-hydroxyethyl methacrylate）（PANCHEMA） was chemically modified by anchoring of phospholipid moieties. The process involved the reaction of hydroxyl groups on the membrane surface with 2-chloro-2-oxo-1,3,2-dioxaphospholane （COP） followed by the ring-opening reaction of COP with trimethylamine. Chemical differences between the original and the modified membranes were characterized by FT-IR and XPS, It was found that the amount of macrophage adhered on the modified membrane surface is substantially lower than that on polyacrylonitrile （PAN） and PANCHEMA membranes under the same condition, The morphological change of the adherent cell is also suppressed by the generation ofphospholipid moieties on the membrane surface.

In our previous work, it was found that large electrospun from chlorinated polypropylene solution doped Bird＇s Nest patterned nanofibrous membranes can be simply with an ionic liquid, and a plausible formation mechanism of Bird＇s Nest patterned architectures was proposed. Here, we use Ansoft Maxwell version 12 software （3D, electrostatic solver） to simulate the electrical field distribution of the electrospinning setup, and to clarify the rationality of proposed formation mechanism. Calculation results clearly show that the introduction of charged nanofibrous bundles would produce a similar patterned electrical field distribution, which definitely confirms the important role of surface residual charges. The proposed mechanism can be well extended to other polymer systems including polystyrene, poly（acrylonitrile-co-acrylic acid） and chitosan/poly（ethylene oxide）.

A key issue in the haploiedntical hematopoietic stem cell transplantation(haplo-HSCT) setting is the search for the best donor, because donor selection can significantly impact the clinical outcomes. We aimed to identify the role of collateral related donors(CRDs) in donor selection for haplo-HSCT through comparing the clinical outcomes between CRDs(n = 60) and maternal donors(MDs, n = 296), which were the last choice of donor selection in immediate related donors(IRDs). The cumulative incidence of graft-versus-host disease was comparable between CRDs and MDs. The 5-year cumulative incidence of relapse and non-relapse mortality was 22.0%(95% CI, 11.3%–32.7%) versus 17.4%(95% CI, 13.0%–21.8%)(P = 0.455) and 25.0%(95% CI, 13.9%–36.1%) versus 23.1%(95% CI, 18.2%–28.0%)(P = 0.721) for the CRDs and MDs, respectively. The 5-year probabilities of disease-free survival and overall survival was 53.2%(95% CI, 40.4%–66.0%) versus 59.5%(95% CI, 53.8%–65.2%)(P = 0.406) and 56.5%(95% CI,43.8%–69.2%) versus 61.8%(95% CI, 56.1%–67.5%)(P = 0.458) for the CRDs and MDs, *** donor/male recipient(FDMR) CRDs were associated with the poorest clinical outcomes, and the clinical outcomes of non-FDMR CRDs were comparable to those of MDs. In summary, our results showed that CRDs did not showed superiority over MDs. Thus, IRDs should be the first choice of donor selection, and CRDs could only be the donors for those without IRDs.
