The results showed that (1) COX-2 mRNA and protein existed in the mature male rat testis. COX-2 was localized in spermatocytes by immunohistochemistry.(2) COX-2 also existed in adult man testis. COX-2 protein was positively stained in spermatocytes and Leydig cells.(3) 2 weeks after administration of rofecoxib, the level of testosterone in the whole testis reached its lower values, being only 50% of control values. However, testosterone level recovered during 4 weeks. After such treatment, histologic examination of these testes showed atrophy of the seminiferous tubules and maturation arrest of spermatogenesis.(4) 2 weeks post-EDS, expression of COX-2 decreased significantly (P.005), in comparison with vehicle-treatment control. 4 weeks after treatment, a new generation of fetal like Leydig cells repopulated in the testicular interstitium resulting in COX-2 expression partially recovered. Although the expression of COX-2 mRNA and protein are enhanced at 8th week after using external testosterone, it wasn't significant higher than control group.

实验研究证明：(1)正常成年雄性大鼠睾丸组织中COX-2在mRNA和蛋白质水平均存在表达，免疫组织化学结果显示COX-2定位于曲细精管内的生精细胞；正常成年男性睾丸组织中同样存在COX-2表达，免疫组织化学结果显示COX-2定位于曲细精管内的生精细胞和Leydig细胞；(2)服用特异性COX-2酶抑制剂rofecoxib 2周后，实验组大鼠睾丸组织内睾酮的含量减少，为正常对照组的50％；持续用药4周后睾丸组织内睾酮浓度逐渐恢复至正常水平；COX-2酶活性降低后病理组织切片显示睾丸内曲细精管萎缩，生精紊乱，持续用药4周时影响最明显；(3)注射特异性Leydig细胞杀灭剂EDS 2周后，实验组大鼠睾丸组织内睾酮浓度降至极低水平时，COX-2的蛋白和基因表达水平也显著低于正常空白对照组（P.005）；使用EDS后第4周，睾丸组织中的睾酮浓度逐渐回升，同样组织中COX-2蛋白表达和mRNA表达水平也相应提高接近正常水平；使用EDS后4周开始给予外源性睾酮，6周和8周时COX-2表达水平的绝对值虽有提高，但与正常大鼠空白对照组比较并无显著性差异，说明外源性雄激素刺激睾丸合成COX-2的作用并不明显。

The low level expression of this gene was observed in some specimens of kidney, heart, lung, thymus, brain and skeletal muscle. It is concluded that the expression of hERMAP in fetal liver approximately consistent with haematopoiesis of fetal liver, and the expression of this gene in bone marrow aged 15-32th fetal weeks coincides with haematopoiesis of fetal bone marrow.

FQ-PCR结果显示，人类ERMAP基因在9-36周胎儿肝脏中均有表达，其表达量从第12周开始升高，18-20周达高峰，21周后逐渐下降；该基因在胎儿骨髓中的表达则从15周开始，27-32周达高峰，之后迅速下降，其表达量低于肝脏；在其余7个脏器中仅有部分标本呈现低水平表达。

The expression of survivin is strongly correlated with tumor recurrence in colorectal cancer, especially haematogenous metastasis. The recurrence rate is significant higher in the group of high Survivin expression than in the group of low-survivin expression. Survivin is the independent dangerous factor related to prognosis.

Survivin的表达与结直肠疮的术后复发相关：结直肠癌术后复发率在Survivin高表达组明显高于Survivin低表达组，是与预后相关的独立危险因子。

By using the arithmetic operation rules of unascertained rational number, the expression of unascertained weight coefficient is derived.

利用未确知有理数的运算规则，推导出系统可靠性分配的未确知权系数表达式。

In this mansion Bely had been rigidly making rational thinking and artistic practice to the end of his life, and always attempted to exert himself in searching for the proper form of expression, which resulted in his deliberate innovation on the artistic form of novels.

别雷一生都是在这一大厦里执着地进行着理性的思辨与创作实践，并始终努力尝试为其艺术思维寻找恰当的表达方式，因此作家便自觉地开始了对长篇小说这一艺术形式的革新。

In theory of approximations, the classic methods of polynomial approximation for rational expression are various interpolations and operator approximations, such as Lagrange interpolation, Hermite interpolation and Bernstein polynomial approximation.

There had been a moment during the breakfast meeting, though, after the backslapping and the small talk and when all of us were seated, with Vice President Cheney eating his eggs Benedict impassively and Karl Rove at the far end of the table discreetly checking his BlackBerry, that I witnessed a different side of the man.

那次早餐会期间，在表示过关心和寒暄以后，我们所有人坐了下来，我注意观察了一下，副总统切尼面无表情地吃着班尼迪克蛋（Eggs benedict，源自美国，以英式松饼、火腿、水煮蛋以及荷兰酱组合而成），卡尔。罗夫在餐桌的远端谨慎地经常查看他的黑莓手机，我目睹了他所不为人知的一面。
