全国小儿血管瘤(淋巴管瘤)研讨会于1991年11月5～7日在西安召开。来自全国各地各级医疗单位各学科(儿外、皮肤、骨科、同位素、口腔等)216名代表参加了会谈。大会收到论文253篇,大会交流134篇。会议期间进行了热烈讨论,充分展示了我国医务人员在小儿血管瘤、淋巴管瘤这个课题上取得的最新科研进展。也是跨学科专题学术交流的一次会议,现就其主要内容归纳如下。一、基础理论研究方面西安医科大学对婴儿血管瘤血管内皮细胞已培养成功,并经组织化学染色检查鉴定证实。培养血管瘤内皮细胞不仅可用于血管瘤的病因、发病机制研究、有效药物的选择,而且还可用于其他血管增生性疾病的研究。他们认为血管瘤是血管内皮细胞一过性增生性疾病。其增生与退化可能与下列因素有关:①内皮细胞本身生理、生化、基因异常或缺陷;②血管形成因子水平升高和(或)血管形成抑制因子水平降低;③相邻细胞对内皮细胞之影响;④细胞外基质Fibronectia Limina等;⑤激素如E_2;⑥免
The National Pediatric Hemangioma (Lymphangioma) Symposium was held in Xi’an on November 5-7, 1991. 216 representatives from various disciplines (children, skin, orthopedics, isotopes, oral cavity, etc.) from medical units at all levels across the country participated in the talks. The conference received 253 papers, the conference exchanges 134. During the meeting, there was a lively discussion, which fully demonstrated the latest scientific research progress made by medical staff in our country on pediatric hemangiomas and lymphangiomas. It is also a conference on interdisciplinary academic exchanges. The main contents of this conference are summarized as follows. First, the basic theoretical research Xi’an Medical University on the hemangioma vascular endothelial cells have been cultured successfully confirmed by histochemical staining. The culturing of hemangioma endothelial cells can be used not only for the etiology, pathogenesis and selection of effective drugs for hemangiomas, but also for the study of other vascular proliferative diseases. They think hemangioma is a transient proliferative disease of vascular endothelial cells. Its proliferation and degeneration may be related to the following factors: ① endothelial cell physiological, biochemical, genetic abnormalities or defects; ② increased levels of angiogenic factors and (or) angiogenesis inhibitory factor levels; ③ adjacent cells on endothelial cells ; ④ extracellular matrix Fibronectia Limina; ⑤ hormones such as E_2; ⑥ free
