Methods Nuclear β-catenin expression was detected by immunohistochemistry in 77 lesions with desmoid-type fibromatosis and 171 other spindle cell lesions, including superficial fibrmoatosis (n=18), nodular fasciitis (n=36), keloid (n=16), scar (n=10), granulation tissue (n=9), synovial sarcoma (n=38), neufibroma (n=13), solitary fibrous tumor (n=12), gastrointestinal stromal tumor (n=10), low-grade myxofibrosarcoma (n=3), low-grade fibromyxoid sarcoma (n=3), and smooth muscle tumor (n=10). In addition, the immunohistochemical expressions of ER-α, ER-β and Ki-67 were examined in all of the lesions with desmoid-type fibromatosis. The nuclear immunohistochemical staining for nuclear βcatenin and ER-β was graded as high level (≥25% of cells), low level (5%-25%) or none.

Fromthese facts,It could be deduced that 8 to 14 pairs of chromosomes possessed a certaindegree of hetorology,which was directly groved to be hybrid origin of P.tomentosaaccording to the good chromosome homology and fertility of P.bolleana and thehybrids of P.tomentosa×P.bolleana,it could be further deduced that the original parentsof P.tomentosa involved probably P.bolleana or P.alba.

从终变期、中期I的染色体构型看，有数目不等的联会程度较差的单价体和棒状二价体出现，在后期I，甚至末期I亦可见到含落后染色体分裂相的细胞，由此推断可能有8~14对染色体表现出一定程度的异源性，鉴于新疆杨以及毛白杨与新疆杨杂交产生的杂种毛新杨的染色体同源性较强、育性较好等现象，进一步推断毛白杨起源亲本可能包括新疆杨或银白杨。

异型性。。。n 异型性：肿瘤细胞形态和组织结构与其同源正常组织存在的差异称之为异型性

The average percent value of G C (49.3%) was less than that of A T (50.7%), there was a bias of the content of G, T in the third codon; The number of transition G-A and T-C were 22, 15 respectively, which were higher than that of transition A-G and C-T, the number of tranversion C-A, T-G is 2 respectively, and other tranversion patterns didnt occur; the probability of transition was higher than that of tranversion , Ts/Tv = 9.5-19, there was the highest number of transition in the third codon. The gamma parameter a of the lst,nd and 3rd codon positions were 0.00572,0.01237 and 1.05239 respectively, they showed that there was adifferent substitution rate at different codon position. Frequences of synonymous codon usage were relatively biased. The average rates of synonymous and nonsynonymous substitution were 0.0787, 0.0011 respectively, there was a significant difference between dS and dN (Z = 4.713, p.01), and the low ratio( CD = 0.0284 .3) of dN/dS ratio impled that there were selective constraints against the nonsynonymous sites in cyt-b gene, The distribution of nonsynonymous codon substitution pattern related to Grantharm distance indicated that the purified selection at 2nd codon positions was more intensive than that at 1st codon positions. The phylogenetic trees supported the view of the double origin of Chinese goose, which means that domestic Chinese goose was derived from Anser cygnoides and domestic European goose, and Yili was derived from Anser anser.

碱基含量分析可知，序列的G C含量(49.3％)＜A T含量(50.7％)，密码子第三位点的G、T含量都有较强的偏倚性；序列间G→A和T→C的转换数(22次和15次)高于A→G和C→T的转换数(10次和9次)，C→A、T→G颠换数均为2次，其余颠换模式均未发生；转换数明显高于颠换数，Ts／Tv=9.5～19，密码子第三位点的转换数最高，呈现了相当强烈的转换偏倚性；密码子第一、二和三位点的gamma分布参数α值分别为0.00572、0.01237和1.05239，表明密码子第一位点的替换速率变异最大，第二位点次之，第三位点的替换速率变异相对较小；编码同一氨基酸的同义密码子并非随机使用，表现出一定程度的使用偏倚性；同义替换速率和非同义替换速率分别为0.0787和0.0011，dS与dN值间的差异极显著(Z=4.713，p＜0.01)，而ω=0.0284，明显小于0.3，表明雁属鹅细胞色素b基因序列经历了中度净化选择作用；单步非同义替换(Sing-step nonsymonymous codon substitution，SSNCS)分布模式与Grantharm距离之间的关系说明密码子的三个位点所受的净化选择强度不同；构建的最大简约树与邻接树拓扑结构一致，支持中国家鹅的双起源学说，即除伊犁鹅外的其它中国鹅品种起源于鸿雁，伊犁鹅和欧洲的郎德鹅、莱茵鹅起源于灰雁。
