角膜移植后患者角膜新生淋巴管与新生血管和炎症的关联

目的:研究角膜移植后角膜新生淋巴管与新生血管和炎症的关联。方法:人角膜取自行二次角膜移植的患者19例。淋巴内皮细胞受体(lymphatic vessel endothelial hyaluronan receptor,LYVE-1)和内皮细胞黏附因子-1(platelet endothelial celladhesion modecule-1,PECAM-1)双重免疫组化法标记角膜中的新生血管和淋巴管,进行淋巴管计数(lymphatic ves-sels counting,LVC)和血管计数(blood vessels counting,BVC),比较BVC、炎症指数(inflammation index,IF)、移植历史(transplantation history,TH)与LVC之间的关联。结果:角膜移植后BVC,IF与LVC间均呈显著性正相关,而TH与LVC间呈显著性负相关。角膜移植后新生淋巴管、血管、眼表炎症间大致成平行发展,新生淋巴管最先退化,其次是眼表炎症,新生血管最后消退。结论:人角膜移植后角膜新生淋巴管与新生血管、眼表炎症之间存在着极为密切的关联。

54例慢性萎缩性胆囊炎两种手术方法的回顾性分析

于2007年1月-2010年12月我院收治54例慢性萎缩性胆囊炎患者,并分为腹腔镜胆囊切除(LC组)28例和开腹胆囊切除术组(OC组)26例,观察两组病例术中出血、术后恢复及并发症情况.结果LC组患者在术中出血量、下床时间、排气、排便时间及平均住院时间上与OC组比较有明显优势,是值得推广的治疗方法.     

鼻咽癌颅底骨侵犯的影像学研究进展

鼻咽部与颅底毗邻,解剖部位深并隐藏,准确判断颅底骨质是否侵犯,关系到放疗计划方案设计。但由于颅底骨质的解剖部位特殊,目前诊断上缺乏病理诊断金标准,依赖于影像学检查诊断。本文就鼻咽癌颅底侵犯的主要影像学近年来诊断进展相关文献进行复习并作综述。     

阻断血管内皮生长因子C促进角膜移植后新生淋巴管和血管的“分离生长”

BACKGROUND: Corneal lymphangiogenesis is beneficial to the transport of corneal antigenic materials, and accelerates the process of antigen presentation, thereby playing an important role in corneal immunity. However, due to the parallel outgrowth of corneal blood and lymphatic vessels in transplanted corneas, it is often difficult to accurately evaluate the role of corneal lymphatic vessels in allograft rejection. OBJECTIVE: To explore the development of corneal lymphangiogenesis and angiogenesis in transplanted rat corneas after the blockade of vascular endothelial growth factor C (VEGF-C). METHODS: 130 rats used to establish corneal allogenic transplantation models were equally randomized into two groups: the anti-VEGF-C group and the control group. VEGF-C was blocked in the anti-VEGF-C group by intraperitoneal injection of neutralizing monoclonal anti-VEGF-C antibody every other day for 2 consecutive weeks. Meanwhile, rats in control groups received intraperitoneal injections of saline. Corneal angiogenesis and lymphangiogenesis were characterized using whole mount immunofluorescence, and the immune rejection of the grafts was evaluated by scoring the rejection index (RI). In addition, the expression of VEGF-C was examined by real-time PCR. The relationship of corneal lymphangiogenesis and angiogenesis to RI in transplanted corneas was also characterized. RESULTS AND CONCLUSION: VEGF-C expression was markedly downregulated after VEGF-C blockade. Corneal lymphangiogenesis developed in parallel with corneal angiogenesis in the control group. While there was a mild reduction in blood vessel area (BVA) and a significant decrease in lymphatic vessel area (LVA) in the anti-VEGF-C group (P < 0.05). In addition, RI was positively correlated with BVA (P < 0.05) and LVA (P < 0.05) in the control group. However, although RI was significantly correlated with BVA (P < 0.05) in the anti-VEGF-C group, the correlation between RI and LVA was not statistically significant (P > 0.05). the graft survival time in the anti-VEGF-C group was significantly increased compared with that in the control group (P < 0.05). Our results show that the outgrowth of lymphatic vessels is separated from that of blood vessels in transplanted corneas by blocking VEGF-C. The blockade of VEGF-C has a significant role in preventing corneal lymphangiogenesis in corneal beds, which results in higher allograft survival rates. 中国组织工程研究杂志出版内容重点：组织构建;骨细胞;软骨细胞;细胞培养;成纤维细胞;血管内皮细胞;骨质疏松;组织工程
