ABSTRACT Skin wound injuries are often accompanied by bacterial infections and severe inflammation. Especially, M1‐type macrophages at the wound site can trigger a cascade of inflammatory responses, mediating a vicious cycle of inflammation. Meanwhile, hypoxia further exacerbates vascular damage and constriction in the wound microenvironment, thereby ...

The research of developing functional artery with collateral circulation in the ischemic hindlimb [PDF]
1、背景与目的 随着社会的发展,血管方面疾病的发病率呈现日益增高的趋势。在众多血管疾病中动脉硬化闭塞症、血栓闭塞性脉管炎等这一类疾病均可能伴随出现下肢缺血的症状。其中手术治疗主要包括人造血管旁路移植、支架植入以及球囊成形术等,但血管移植通常会形成血栓而只有短期的通畅性,支架植入和血管成形术往往又会造成扩张部位的再狭窄。对于血管病变广泛而无法进行手术或腔内治疗的患者,就只能通过药物保守治疗,通常是采用扩血管、抗凝和抗血小板等方法来改善其血液供应,随着病程的发展,药物往往不能起到很好的效果 ...

ABSTRACT Two‐dimensional (2D) nonlayered niobium nitrides have attracted considerable interest for electrochemical energy storage. However, the synthesis of these materials is hampered by their nonlayered crystal structures, which are characterized by strong three‐dimensional chemical bonding.

ABSTRACT Efficient and durable bifunctional electrocatalysts are vital for scalable water electrolysis. Here, we realize cobalt‐vacancy (Covac) engineering in CoFeP supported on N,P‐codoped carbon nanocages (Co1‐vacFeP/NPC) through a simple route comprising a CoFe Prussian blue analog precursor, phosphidation–pyrolysis, tannic‐acid etching, and a ...

【目的】观察皮肤干细胞在结膜去细胞基质上的生长和分化情况,探讨利用皮肤干细胞及结膜去细胞基质构建人工结膜的可能性。【方法】将体外分离培养的1~2代人皮肤干细胞接种于人结膜去细胞基质上,在体外观察细胞的分化情况。标本分别行HE染色、人上皮细胞角蛋白CKl9单克隆抗体、结膜上皮细胞特异性标记蛋白CK8抗体、CK13抗体、MUC5A/C抗体免疫组化鉴定。【结果】皮肤干细胞在结膜去细胞基质等模拟的体外微环境下可形成类似结膜上皮细胞的复层增生,并有类结膜上皮细胞特异性标记蛋白表达,呈CK8抗体、CK13抗体 ...

目的从单克隆抗体水平研究同种异体肾移植受者多反应性抗体与HLA抗体的相关性,探讨多反应性抗体是否为HLA抗体尤其是非供体特异性抗体产生的原因之一。方法从肾移植患者外周血细胞及手术切除的移植肾组织中分离出B淋巴细胞,并于体外永生化培养获得单克隆B细胞,分别检测B细胞分泌的抗体对HLA抗原及凋亡细胞的反应性。结果共获得107个B细胞克隆,检测发现每个B细胞克隆在体外培养过程中均分泌抗体。其中有4个单克隆B细胞分泌的抗体可以与多种HLA抗原发生反应,而这些HLA抗原之间并非都有共用的抗原决定簇。进一步研究发现,

乳腺外科教学本身存在课时较少、内容较多、教学形式相对固定等特点,使传统的乳腺外科教学模式比较枯燥单一。如何通过利用网络、多媒体等技术改良教学模式,提高教学效果是目前乳腺外科教学的重点。我们在乳腺外科本科生教学中,利用多种新的多媒体技术在教学课件中融入了高清组图、动态图片及三维(3-dimension,3D)动画等多媒体元素,从而制作了一套全新的规范化、形象化的多媒体课件。
