Methods The expressions of MAGE-3 in tumor tissue, para-tumor tissue of (5±1)cm from border of tumor tissue, tissue of resection border and polypus were detected by RT-PCR. Results MAGE-3 expression was positive in 14 of 33 (42.42%) samples of rectal cancer, 6 of 33 (18.18%) of para-tumor tissue, and 5 of 33 (15.15%) of resection border tissue respectively.

采用RT-PCR法，对33例直肠癌患者的癌组织及其相应距肿瘤边缘(5±1)cm的癌旁组织和手术切缘以及3例直肠息肉标本的MAGE-3的表达情况进行检测，并对RT-PCR扩增产物中的目的基因片段进行DNA测序验证。

The analysis of SAR reveals that the activities of target compounds are closely associated with the electron-withdrawing substituents at the para position of 1-aryl-1, 2, 4 -triazoles as well as with the substituents such as sulfonyl and methylthio groups at the 3 position of 1, 2, 4 -triazoles; And the introduction of sulfamoyl moiety at the para position of 5-aryl-1,2,4-triazoles also has significant influence on the anti-inflammatory activity of these compounds.

构效关系分析发现，在三唑环1位芳基的对位引入F、Cl、Br吸电子基团以及3位引入磺酰基和甲硫基，对抗炎活性有重要的意义；在三唑环5位芳基的对位引入氨磺酰基，对抗炎活性有较大影响。

And it is noted that the velocity field in a hydrocyclone is divided to two areas, i.e. the outer para-free-vortex and the inner para-forced vortex. The boundary surface of the velocity field is the maximum tangent velocity track surface, which is a cylinder when the hydrocyclones structure is reasonable.

分析研究结果表明，旋流器的切向速度场由外部准自由涡和内部准强制涡两个区域构成，其分界面为最大切向速度vtmax的轨迹面，结构设计合理时，此轨迹面为一圆柱面。

The para-/ortho- product isomer ratio is 6.2 for the nitration of chlorobenzene at 18℃ for 8h with n/n(NH4NO3)=5. The para-/ortho- product isomer ratio is 14.0 for the nitration of bromobenzene at 0℃ for 8h with n/n(NH4NO3)=5. The pars-product, p-nitrobromobenzene, from the nitration of bromobenzene in [HSO4] under 0℃ precipitates with 98% purity, which facilitates the separation of the pure isomert.

其中氯苯在18℃下反应8h，三氟乙酸酐/硝酸铵为4时产物的对邻比达到6.2，而溴苯在0℃下反应8h，TFAA/硝酸铵为5时产物的对邻比可达到14.0，并且生成的对硝基溴苯可以从反应液中析出，得到对硝基溴苯含量为98%的产物。

Analogous complexes 3a" and 4a"= CpRu(PPh32, Ar = para-C6H4OMe containing methoxy group at the para-position of gem-diphenyl group were similarly obtained from protonation of the corresponding acetylide complexes via formation of vinylidene intermediate. But only complex 3a'= CpRu(PPh32, Ar2 = fluorenyl is stable in solution, and decomposed to unidentified complex when heated to reflux in THF. Deprotonation of complex 4a in the presence of base gives neutral acetylide complex 6a.

在两个相邻位置的苯基对位位置上接有一甲氧基的衍生物3a&和4a&也可利用类似的质子化反应合成，唯有错合物3a'= CpRu(PPh32， Ar2 = fluorenyl 可以稳定於溶液中，不会进行上述反应，如将其溶於四氢呋喃溶液加热至沸腾则会分解产生无法鉴定的化合物。

Para siempre, para siempre me tendrasescondido en tu memoria, en tu alma,en tu verdad.

永远，永远，你可以把我深藏在你的回忆，你的灵魂和你的真相里

Therefore, thorough surgical staging including omentectomy, total hysterectomy, bilateral salpingo-oophor ectomy, pelvic and para-aortic lymphadenectomy, multiple biopsies of the upper abdomen, and saline washings of the pelvic and para-colic spaces should be performed in patients with this disease.

所以，彻底的分期手术应包括大网膜切除、全子宫切除、两侧卵巢输卵管切除、骨盆腔和主动脉林巴结切除、上腹部切片和生理食盐水冲洗骨盆腔和两侧大肠部位。

Have been investigated for the first time, obtaining poly , copolymers of para-diethynylbenzere with propargyl alcohol , propiolic acid with ethynylbenzene , propiolic acid with para-diethynylbenzene, and propiolic acid with propargyl alcohol.

制得丙炔酸均聚物，以及对二乙炔苯与丙炔醇，丙炔酸与苯乙炔，丙炔酸与对二乙炔苯，丙炔酸与丙炔醇共聚物。

Results showed N_2O_5/CH_2Cl_2 was a relatively mild system, its nitrating ability of arene was weak, but the para-selectivity of product was satisfactory. Series of ZSM-5 catalysts could improve para-selectivity of product and meanwhile enhance the yield.

结果表明：N_2O_5／CH_2Cl_2是一个相对温和的硝化体系，对芳烃的硝化能力很弱，但产物的对位选择性很好；ZSM-5系列催化剂在显著提高对位产物比例的同时也能提高硝化的产率。
