Genesis,development and metabasis of solid tumor have close relationship with tumor vessel angiogenesis; extracellular matrix degradation is the key point for tumorous infiltration and metabasis;the significant biology characteristic of tumor cell is the disorder of tumor cell differentiation and apoptosis.

骨巨细胞瘤血管生成是近年来研究热点，实体瘤的发生、发展及转移与肿瘤的血管生成密切相关；细胞外基质降解在肿瘤的浸润和转移中起到关键作用；肿瘤细胞的分化凋亡障碍与无限增殖能力是肿瘤细胞的重要生物学特征。

Giant cell tumor of bone is a kind of common bone tumor,which has characteristics of high recurrence rate and invasion.recently,tumor vessel angiogenesis has been the warm spot of research.genesis,development and metabasis of solid tumor have close relationship with tumor vessel angiogenesis; extracellular matrix degradation is the key point for tumorous infiltration and metabasis;the significant biology characteristic of tumor cell is the disorder of tumor cell differentiation and apoptosis.the correlated research has very important significance for judging gct prognosis and guiding therapy.

骨巨细胞瘤（giant cell tumor of bone，gct）是一种常见骨肿瘤，由于其高复发率和强侵袭性，备受临床骨科工作者的关注。骨巨细胞瘤血管生成是近年来研究热点，实体瘤的发生、发展及转移与肿瘤的血管生成密切相关；细胞外基质降解在肿瘤的浸润和转移中起到关键作用；肿瘤细胞的分化凋亡障碍与无限增殖能力是肿瘤细胞的重要生物学特征。骨巨细胞瘤生物大分子研究的不断深化对判断gct的预后及指导治疗有重要意义。

Stratum basale: the innermost layer of epidermis, it's the source to produce cells of every layer, once the epidermis is damaged, cells of this layer would proliferate and repair it without any scar, cells of this layer use about four weeks to finish the process of produced-cornified-detached .

基底层：是表皮的最里层，是表皮各层细胞的生成之源，每当表皮破损，这种细胞就会增生修复，不留任何遗痕，基层细胞从生成到经过角化脱落大约四个星期。

The testis index, testis volumes were same as the annual changes of testis mass. The curves of annual variation were all unimodality.2 The spermatogenetic cycle of Myospalax cansus comprises seven stages with significant features: Stage I , from February to April, the testis were at the stage of spermatogonia proliferation. In this period, testis index and the number of spermatogonia began to rise. Other spermatogenic cells had not yet formed; Stage II to III, from March to April, primary spermatocyte meiosis period. The testis index was highest in this stage, and spermatogenic cells were in spermatocyte stage, the primary spermatocyte meiosis generated to secondary spermatocyte; Stage IV, from April to May, spermatocytes continued to split, germ cells appeared in seminiferous tubules; Stage V, in May, sperm formation, spermatids of seminiferous tubules were transformed to spermatozoa, a large number of sperms existed in the lumen; Stage VI, spermatozoa emission period, from May to June, testis index were a significant drop and mature spermatozoa excluded gradually; VII, the testicular activity ceased basically from July to September, November to January of the following year, the spermatogenic activity ceased completely. Therefore, Myospalax cansus are animals of seasonal reproduction, spermatogenesis cycle is discontinuous type.

睾丸系数、体积和重量的年周期变化规律一致，变化曲线呈现单峰型。2甘肃鼢鼠雄性生殖腺的年周期活动由7个特征明显的时期构成：Ⅰ期，2～3月份，精原细胞增殖期，睾丸系数开始上升，精原细胞进行有丝分裂，其他生精细胞尚未形成；3～4月份为Ⅱ～Ⅲ期，初级精母细胞成熟分裂期，睾丸系数达到最大，生精细胞大多处于精母细胞阶段，初级精母细胞减数分裂生成次级精母细胞；Ⅳ期，4～5月份精母细胞继续进行分裂，精细胞在生精小管内出现；Ⅴ期，5月份，精子形成期，曲细精管中精细胞变态成精子，在管腔中存在大量的精子；Ⅵ期，精子排放期，5～6月份，睾丸系数显著下降，成熟精子从生精小管上脱离，逐渐排除；Ⅶ期，精原细胞停滞期，7～9月份睾丸生精活动基本停滞，11～翌年1月，生精活动完全停止。
