Secondly, by applying inverse Fourier integral transform to the displacement, and uniting the constitutive and geometrical equations, the analytical expression of stress in Laplace domain were derived. Thirdly, by defining dislocation density functions, the Cauchy singular integral equations were obtained according to the boundary condition and interface connection conditions, and the problem was reduced to algebraic equations by Chebyshev orthogonal polynomial. Based the these, the unknown coefficient of the algebraic equations can be solved by Schmidt method. Finally, the time response of dynamic stress intensity factor and energy release rate are obtained by inverse Laplace transform.

Objective It was reported that rALR (rat augmenter of liver regeneration) distribute in most of tissue and organ of rat, no-tissue specility; mRNA expression of rALR was identified variedly in different tissue, strongest in testis. But nowadays there was not some study on ALR in rat testis. Here to confirm the expression and localization of ALR in infancy,adult and old rat testis,comparing the change of ALR expression degree before per 70 PH and after per 70 PH. In order to evaluate expression principle of ALR in rat testis and know if ALR has tight connection with spermatogenesis and development of testis, to explore the relation between ALR and reproduction, to discover the possible expression character and functional methods of ALR.

From the angle of the dialectical relation of difference and identity, connecting further peoples real patterns of expression (the pattern of expression of the category, the pattern of expression of groups, the pattern of expression of the individuals), we may make the essence of human being to be particularized to three aspects of essence of the category, the groups and the individuals, these three aspects not only prescribe intrinsically the corresponding patterns of expression ofjustice (the justice of the category, the justice of the groups, the justice ofthe individuals), but also prescribe intrinsically the corresponding contents of development and ways of realization of justice.

从差异与同一的辩证关系角度，再结合人的现实的表现样态(类的表现样态、群体的表现样态、个体的表现样态)，我们可以把人的本质具体化为类本质、群体本质、个体本质三个方面，这三个方面不仅内在地规定着相应的正义的表现形态(类的正义、群体的正义、个体的正义)，而且内在地规定着相应正义的发展内容和实现方式。

Results 2 ClAdo and 2 CldAdo had different cytotoxicities on the cells, while 2' dAdo had no cytotoxicity on the cells. 2 CldAdo blocked the cell growth at the phase of S and G2/M, while 2 ClAdo at the phase of G0/G1. 2 CldAdo mainly induced cell necrosis, while 2 ClAdo induced both cell necrosis and apoptosis. Down regulated Bcl 2 expression and up regulated p53 and Bax expression were associated with 2 ClAdo, while 2 CldAdo down regulated Bcl 2 expression and up regulated mildly p53 expression without any effect on Bax expression.

The positive expression both of p14ARF and mtp53 protein in NSCLC tissues were significantly different from that in nonmal lung tissues and tissues adjacent to the cancer (P.01).The expression of p14ARF protein was correlated with pathological degree（P＜0.01）,but it was uncorrelated with pathological staging,lymphaden metabasis and vessel invasion(P＞0.05).The expression of mtp53 protein was correlated with clinical pathology staging,pathological degree and vessel invasion(P＜0.05 or P＜0.01),but it was uncorrelated with lymphaden metabasis(P＞0.05).(2) The coexpression of p14ARF and mtp53 was 36.7％,their consistency was 38.8％,but the expression of p14ARF protein were negatively correlated with the expression of mtp53 protein(r=-0.3553,P＜0.001).Conclusion The results suggest that the decrease of p14ARF and the increase of mtp53 protein may play an important role in the genesis and development of NSCLC.
