The skin lesions may consist of multiple large tumors, commonly on the scalp and around the neck,and small pearly,pink papules and plaques on the trunk, chin, ears, and around the nostrils. Here, we report a 2-year-old boy with characteristic stiffness of the knees and elbows and pink confluent papules on the paranasal folds, and periauricular and perianal regions. He also had hard nodules all over the scalp and around the mouth, and severe gingival hyperplasia. The lesions were totally excised and clinicopathological diagnosis was JHF.展开更多

It is characterized by papulonodular skin lesions, soft tissue masses, gingival hypertrophy, osteolytic bone lesions and flexion contractures of the large joints. Here, we report a 14-year-old girl with characteristic clinical features of JHF with early fatal outcome. Dermatopathologic examination of the early lesions however constantly lacked the so-called hyalin changes in multiple skin biopsies. According to our experience; dermatopathological features of this entitity is not often and always consists of classical hyalinisation. Only larger lesions with long duration should expected to be exhibiting those features. Therefore we suggest that; JHF may often present itself as Juvenil Non-Hyaline Fibromatosis: JHF without prominent hyaline changes. And thus this fact should not change the actual diagnosis and prognostic implications.展开更多
目的：预测并综合分析人卵透明带3（human zona pellucida 3,hZP3）蛋白的二级结构及其B细胞抗原表位。方法：以hZP3蛋白的基因序列为材料,采用Garnier-Robson法、Chou-Fasman法和Karplus-Schulz法预测其结构蛋白的二级结构及蛋白骨架...目的：预测并综合分析人卵透明带3（human zona pellucida 3,hZP3）蛋白的二级结构及其B细胞抗原表位。方法：以hZP3蛋白的基因序列为材料,采用Garnier-Robson法、Chou-Fasman法和Karplus-Schulz法预测其结构蛋白的二级结构及蛋白骨架区的柔韧性,采用Kyte-Doolittle法对蛋白的亲水性进行分析,Emini法预测蛋白的表面可能性,Jameson-Wolf法预测蛋白的抗原指数。结果：hZP3蛋白含有较多的β折叠和转角结构。该蛋白第27～31、36～46、114～133、140～151、237～240和324～329区段可能是α-螺旋中心;hZP3蛋白分子第52～54、60～67、74～78、100～111、158～169、181～185、190～193、210～218、226～229、311～317、335～349和353～360区段可能是β-折叠中心。hZP3蛋白具有多处抗原指数较高的区段,其中近中部区段和近羧基端的第92～95、132～137、171～178、239～245、252～255、279～286、292～305和319～324区段含有潜在的B细胞优势抗原表位。结论：以蛋白质的二级结构预测作为辅助手段,用抗原指数、亲水性参数和表面可能性参数预测hZP3蛋白的B细胞抗原表位,为实验确定hZP3蛋白的B细胞抗原表位并以此进行免疫避孕研究奠定基础。展开更多
