Antitumor angiogenic therapy has been shown promising in the treatment of several advanced cancers since the approval of the first antiangiogenic drug Avastin in 2004. Although the current antiangiogenic drugs reduce the density of tumor blood vessels and result in tumor shrinkage at the early stage of treatment, recent studies have shown that antiangiogenic therapy has transient and insufficient efficacy, resulting in tumor recurrence in patients after several months of treatment. Blockage of blood and oxygen supplies creates a hypoxic and acidic microenvironment in the tumor tissues, which fosters tumor cells to become more aggressive and metastatic. In 2001, Jain proposed tumor vascular normalization as an alternative approach to treating cancers based on the pioneering work on tumor blood vessels by several other researchers. At present, normalizing the disorganized tumor vasculature, rather than disrupting or blocking them, has emerged as a new option for anticancer therapy. Preclinical and clinical data have shown that tumor vascular normalization using monoclonal antibodies, proteins, peptides, small molecules, and pericytes resulted in decreased tumor size and reduced metastasis. However, current tumor vascular normalizing drugs display moderate anticancer efficacy. Accumulated data have shown that a variety of vasculogenic/angiogenic tumor cells and genes play important roles in tumor neovascularization, growth, and metastasis. Therefore, multiple-targeting of vasculogenic tumor cells and genes may improve the efficacy of tumor vascular normalization. To this end, the combination of antiangiogenic drugs with tumor vascular normalizing therapeutics, as well as the integration of Western medicine with traditional Chinese medicine, may provide a good opportunity for discovering novel tumor vascular normalizing drugs for an effective anticancer therapy.

Netrin-1 (NT-1) is one of the axon-guiding molecules that are critical for neuronal development. Because of its structural homology to the endothelial mitogens, NT-1 may have similar effects on vascular network formation. NT-1 was shown to be able to stimulate the proliferation and migration of human cerebral endothelial cells in vitro and also promote focal neovascularization in adult brain in vivo. In the present study, we reported the delivery of NT-1 using an adeno-associated virus (AAV) vector (AAV-NT-1) into mouse brain followed by transient middle cerebral artery occlusion (tMCAO). We found that AAV vectors did not elicit a detectable inflammatory response, cell loss or neuronal damage after brain transduction. The level of NT-1 was increased in the AAV-NT-1-transduced tMCAO mice compared with the control mice. Furthermore, the neurobehavioral outcomes were significantly improved in AAV-NT-1-transduced mice compared with the control animals (P<0.05) 7 days after tMCAO. Our data suggests that NT-1 plays a neuronal function recovery role in ischemic brain and that NT-1 gene transfer might present a valuable approach to treat brain ischemic disorders.

Peritoneal dialysis (PD) is an established form of renal replacement therapy. Long-term PD leads to morphologic and functional changes to the peritoneal membrane (PM), which is defined as peritoneal fibrosis, a known cause of loss of peritoneal ultrafiltration capacity. Inflammation and angiogenesis are key events during the pathogenesis of peritoneal fibrosis. This review discusses the pathophysiology of peritoneal fibrosis and recent research progress on key fibrogenic molecular mechanisms in peritoneal inflammation and angiogenesis, including Toll-like receptor ligand-mediated, NOD-like receptor protein 3/interleukin-1β, vascular endothelial growth factor, and angiopoietin-2/Tie2 signaling pathways. Furthermore, novel strategies targeting peritoneal inflammation and angiogenesis to preserve the PM are discussed in depth.

3D打印支架植入后激起的免疫反应是组织修复效果的主要决定性因素。因此,巧妙调控免疫反应的支架材料具有高效修复组织的潜能。本研究受抗原特异性免疫反应对血管新生促进作用的启发,通过动态共价键将介孔二氧化硅微棒(MSR)/聚乙烯亚胺(PEI)/卵清蛋白(OVA)自组装疫苗与3D打印自固化磷酸钙骨水泥(CPC)基支架结合,构建了一种具有调控局部体液免疫反应功能的组织修复支架。通过局部释放OVA激活体液免疫反应,支架可有效募集抗原特异性CD4+ 2 型辅助性T细胞(Th2 细胞),从而促进支架植入早期的血管新生;在提供充足和丰富的血供环境的同时,MSR微棒中释放的硅离子还能有效加速骨再生。在室温下稳定成型的自固化磷酸钙基打印浆料能够促进功能性氧化透明质酸在材料中的均匀分布和结构保持,并构建具有均匀连通孔道的支架。将MSR/PEI 作为抗原载体共价结合于富含醛基的支架,可实现OVA的稳定释放。在体外实验中,该疫苗负载支架有效募集并激活了树突细胞使树突细胞呈递抗原,还促进了骨髓间充质干细胞(BMSC)成骨分化。在皮下包埋实验中,疫苗负载支架增加了Th2 细胞在脾脏中的比例,局部募集了抗原特异性T细胞并促进了支架内的血管新生。此外,原位颅骨缺损修复模型结果表明,负载疫苗的支架可促进血管化骨组织再生。总之,该方法为具有促进血管新生功能个性化植入体的设计提供了一种新思路。

19F磁共振成像(MRI) 的研究可追溯到30多年前。在这30多年间,氢原子核(1H)成像技术迅速发展,并在全球得到广泛应用,使得磁共振成像成为生物医学诊断成像技术中不可缺少的支柱。多年来,由于各种原因,对19F成像技术的研究进展缓慢。但是在过去的十年间,尤其是最近几年,19F成像的研究和临床相关性呈爆发式发展。部分原因归结为MRI仪器、19F/1H线圈设计以及临床前和临床核磁共振仪的超高速脉冲序列的发展。这些成就再加上对解剖生理学分子成像技术的兴趣以及一批创新造影剂的出现使19F的概念进入了早期的临床评估中。本篇综述重点探讨以液态全氟化碳化合物为基础的造影剂,并试图呈现这段丰富的研究和发展历史。

人工设计的非接触式多细胞共培养模型可以模仿人体组织的细胞内微环境,但其发展始终面临各种挑战。本研究利用3D打印技术,成功制得了一种含β-磷酸三钙/羟基磷灰石(β-TCP/HA)的细胞容器样支架,该支架设计了四种不同形状的微孔结构:三角形、正方形、平行四边形和长方形微孔结构。这些支架可以在非接触的方式下同时培养四种细胞。本研究构建了一种由人骨髓间质干细胞(HBMSC)、人脐静脉内皮细胞(HUVEC)、人脐静脉平滑肌细胞(HUVSMC)、人真皮成纤维细胞(HDF)组成的3D共培养模型,用以研究这些细胞在促进骨生成和血管生成过程中细胞的个体效应与协同效应。结果表明,相较于在3D细胞容器中仅培养一种细胞,共培养三种或四种细胞展现出了更高的细胞增殖率。HBMSC与HUVEC的细胞间相互作用的研究表明,含有四种独立空间结构的3D细胞容器可以通过放大共培养细胞的旁分泌效应促进细胞的骨生成和血管生成能力。此外,在3D细胞容器中建立多细胞非接触体系,特别是含有三种或四种细胞的共培养体系,相对于单细胞培养模式与两种细胞共培养模式来说,在促进细胞成骨分化和成血管分化方面展现出明显的优势。本研究为基于支架的多细胞非接触式共培养体系的发展提供了新的研究方向。
