| 1 | Identification of Fucans from Four Species of Sea Cucumber by High Temperature ~1H NMR显示文摘Acidic polysaccharide, which has various biological activities, is one of the most important components of sea cucumber. In the present study, crude polysaccharide was extracted from four species of sea cucumber from three different geographical zones, Pearsonothuria graeffei(Pg) from Indo-Pacific, Holothuria vagabunda(Hv) from Norwegian Coast, Stichopus tremulu(St) from Western Indian Ocean, and Isostichopus badionotu(Ib) from Western Atlantic. The polysaccharide extract was separated and purified with a cellulose DEAE anion-exchange column to obtain corresponding sea cucumber fucans(SC-Fucs). The chemical property of these SC-Fucs, including molecular weight, monosaccharide composition and sulfate content, was determined. Their structure was compared simply with fourier infrared spectrum analyzer and identified with high temperature 1H nuclear magnetic resonance spectrum analyzer(NMR) and room temperature 13 C NMR. The results indicated that Fuc-Pg obtained from the torrid zone mainly contained 2,4-O-disulfated and non-sulfated fucose residue, whereas Fuc-Ib from the temperate zone contained non-, 2-O- and 2,4-O-disulfated fucose residue; Fuc-St from the frigid zone and Fuc-Hv from the torrid zone contained mainly non-sulfated fucose residue. The proton of SC-Fucs was better resolved via high temperature 1H NMR than via room temperature 1H NMR. The fingerprint of sea cucumber in different sea regions was established based on the index of anomer hydrogen signal in SC-Fucs. Further work will help to understand whether there exists a close relationship between the geographical area of sea cucumber and the sulfation pattern of SC-Fucs. | WU Nian CHEN Shiguo YE Xingqian LI Guoyun YIN Li'ang XUE Changhu | 2014 | Journal of Ocean University of China2014，13，5： | 2 |

| 6 | Macrophage polarization in diabetic wound healing显示文摘Impaired wound healing is one of the severe complications of diabetes.Macrophages have been shown to play a vital role in wound healing.In different wound environments,macrophages are classified into two phenotypes:classically activated macrophages and alternatively activated macrophages.Dysregulation of macrophage phenotypes leads to severely impaired wound healing in diabetes.Particularly,uncontrolled inflammation and abnormal macrophage phenotype are important reasons hindering the closure of diabetic wounds.This article reviews the functions of macrophages at various stages of wound healing,the relationship between macrophage phenotypic dysregulation and diabetic wound healing and the mechanism of macrophage polarization in diabetic wound healing.New therapeutic drugs targeting phagocyte polarization to promote the healing of diabetic wounds might provide a new strategy for treating chronic diabetic wound healing. | Xingqian Wu Wenjie He Xingrui Mu Ye Liu Junyu Deng Yiqiu Liu Xuqiang Nie | 2022 | Burns & Trauma2022，10，1： | 0 |
