| 1 | Human umbilical cord mesenchymal stem cell-loaded amniotic membrane for the repair of radial nerve injury显示文摘In this study,we loaded human umbilical cord mesenchymal stem cells onto human amniotic membrane with epithelial cells to prepare nerve conduits,i.e.,a relatively closed nerve regeneration chamber.After neurolysis,the injured radial nerve was enwrapped with the prepared nerve conduit,which was fixed to the epineurium by sutures,with the cell on the inner surface of the conduit.Simultaneously,a 1.0 mL aliquot of human umbilical cord mesenchymal stem cell suspension was injected into the distal and proximal ends of the injured radial nerve with 1.0 cm intervals.A total of1.75×107cells were seeded on the amniotic membrane.In the control group,patients received only neurolysis.At 12 weeks after cell transplantation,more than 80%of patients exhibited obvious improvements in muscular strength,and touch and pain sensations.In contrast,these improvements were observed only in 55–65%of control patients.At 8 and 12 weeks,muscular electrophysiological function in the region dominated by the injured radial nerve was significantly better in the transplantation group than the control group.After cell transplantation,no immunological rejections were observed.These findings suggest that human umbilical cord mesenchymal stem cell-loaded amniotic membrane can be used for the repair of radial nerve injury. | Zhi Li Hanjiao Qin Zishan Feng Wei Liu Ye Zhou Lifeng Yang Wei Zhao Youjun Li | 2013 | Neural Regeneration Research2013，8，36： | 13 |
| 2 | Synergistic therapy of magnetism-responsive hydrogel for soft tissue injuries显示文摘Soft tissue injury is very common and associated with pain,tissue swelling and even malformation if not treated on time.Treating methods include cryotherapy,electrical therapy,ultrasound therapy and anti-inflammatory drug,but none of them is completely satisfying.In this work,for a better therapeutic effect,drug therapy and pulsed electromagnetic field(PEMF)therapy were combined.We constructed a drug delivery system using the tetra-PEG/agar hydrogel(PA).By incorporating Fe3O4 NPs into the hydrogel network,a magnetism-responsive property was achieved in the system.The cytotoxicity and in vivo study showed a good biocompatibility of the PA/Fe3O4 hydrogel.A magnetism-controlled release was attained by the incorporation of Fe3O4.Finally,in vivo study showed a better performance of the DS-loaded PA/Fe3O4 compared with the commercially available DS ointment regarding the recovery of the injured soft tissue.Therefore,this magnetism-responsive hydrogel may represent a promising alternative to treat soft tissue injury. | Lining Zhang Xiuqin Zuo Shengjie Li Mi Sun Huimin Xie Kai Zhang Jikun Zhou Liyun Che Junxuan Ma Zishan Jia Fei Yang | 2019 | Bioactive Materials2019，4，1： | 7 |

| 4 | Anatomical Structure Comparison Between Leaves of Two Winter Wheat Cultivars with Different Cold/Freezing Tolerance Under Low Temperature Stress显示文摘Winter wheat (Triticum aestivum) cultivars Dongnongdongmai 1 with strong cold/freezing tolerance and Jimai 22 with weak cold/freezing tolerance were used for investigating the difference of microstructure and ultrastructure between leaves of two cultivars under low temperature stress (5℃ and -15℃) using optical and electron microscope. The results showed that there was no obvious difference between leaves of Dongnongdongmai 1 and Jimai 22 in microstructure. However, the difference between those leaves was distinct in ultrastructure. The grana lamella and stroma lamella were stacked regularly and arranged parallelly along the long axis of chloroplasts in cv. Dongnongdongmai 1, while the arrangement directions of thylakoids in Jimai 22's leaves were so irregular as to form various angles with the long axis of chloroplasts. At -15℃, the mitochondrias were swelled to be round and the structure of cristaes became blurry in both cultivars' leaves, while some cristaes of Jimai 22 disappeared. These results would provide theoretical evidence for selecting cold/freezing tolerant winter wheat germplasm resources. | YU Jing CANG Jing ZHOU Zishan LIU Lijie | 2011 | Journal of Northeast Agricultural University(English Edition)2011，18，3： | 1 |

| 6 | Estimates of Autumntime Benthic Secondary Production in Laizhou Bay and Adjacent Bohai Sea Waters显示文摘The whole metazoan community inhabiting Laizhou Bay and adjacent Bohai Sea waters were sampled in late autumn,2006.Secondary production estimates for macrofauna and meiofauna were made separately.Total benthic secondary production was as high as 8.38 ± 4.08 g ash-free dry weight(AFDW) m-2 a-1,which represented the autumn production level.In general,macrofaunal secondary production in Laizhou Bay was much lower than that in adjacent Bohai Sea areas.In contrast,meiofaunal secondary production in Laizhou Bay was higher than that in adjacent Bohai Sea areas.Macrofauna contributed 61% to benthic secondary production(5.09 ± 3.26 g AFDW m-2 a-1),lower than the value in previous studies in Bohai Sea.Sediment granulometric characteristics and bottom-water salinity could explain the substantial variability in the macrofauna biomass and production.Meiofaunal production was an important component of benthic production and exceeded macrofauna production under exceptional conditions,e.g.in Laizhou Bay,where macrofauna was restricted.Chlorophyll pigments(Chl-a) concentrations in sediment explained the general meiofaunal biomass and production distribution here. | HUA Er ZHOU Hong ZHANG Zhinan YU Zishan | 2010 | Journal of Ocean University of China2010，9，3： | 0 |
