Treatment of cisplatin-resistant cell lines with an inhibitor of DNA methyltransferases, 2-deoxy-5'azacytidine, results in partial reversal of DNA methylation, re-expression of epigenetically silenced genes including hMLH1 and sensitisation to cisplatin both in vitro and in vivo.

DNA甲基转移酶抑制剂2 -脱氧- 5'氮胞苷可部分逆转顺铂耐药细胞株的DNA甲基化，在体外和体内使后生沉默基因包括hMLH1基因重新表达并增加对顺铂的敏感性。

The high expression of mmp-2 and cd44v6 were positively correlated with lymph node metastasis and fibromembranous infiltration （p＝0.011, p＝0.034和p＝0.022, p＝0.001）.the expression of mmp-2 was positive relation to that of cd44v6 （r＝0.427,p＝0.002）.conclusion the detection of expression about mmp-2 and cd44v6 in esophageal carcinoma may be helpful to judge the malignant behavior,metastasis and progronsis.

食管癌组织中mmp-2表达与cd44v6表达呈正相关（r＝0.427，p＝0.002）。结论 mmp-2和cd44v6表达是食管癌发生与发展的重要促进因子，其过度表达与食管癌浸润转移密切相关。检测mmp-2和cd44v6蛋白表达可作为判断食管癌预后的客观指标。

4Complications:After operation peritonitis appeared in 5cases,among which were 2of intestinal obstruction,and 1 necrosis of left hemicolon.Conclusion:The chemotherapy of selective arterial drug perfusion before an operation reduce the tumor and stiumulate inflammatory reaction and fibroplastic proliferation around it.Thus increases excision rate as well as decreases local recurrence rate and possiblity of cancer merastasis.However,it also leads to some toxic side reaction and possible intestinal obstruction and necrosis.

于直肠癌手术切除前先行选择性动脉药物灌注化疗，可使肿瘤缩小，并刺激瘤周炎性反应和纤维组织增生，从而提高手术切除率，降低术后局部复发和远处转移可能，该方法有一定的毒副反应和发生肠梗阻、肠坏死的潜在危险。

The presence ofelectron donor(methoxy or methylenedioxy group) and electronacceptor anhydride group） moieties on phenyl fulgide derivativesleads to an intramolecular charge transfer upon exication that results ina solvatochromic effect.

可将苯基俘精酸酐视为由给电子基和得电子基两部分组成，分子内的电荷转移是造成正溶剂效应的主要原因。

The higher the inoculation concentration of the strain is during seed germination, the more quantity the strain in host plant tissues. When strain B504-1121 was inoculated on lower petioles, it could transfer into upper tissues, however it only habitate in leaves if it was inoculated on leaves.

在下部叶片叶柄处接种的菌体可向上移动，通过茎进入上部叶片；在叶部接种的菌，则只在接种叶内定殖，不再向其他部位转移。

Combining introperitoneal hyperthermic chemoperfusion and local radiofrequency thermotherapy can be effective management to apply and enhance quality of life and T lymphocyte immunologic function.

局部射频透热化疗适用于晚期腹盆腔肿瘤伴腹腔、盆腔、肝脏转移者，可获得较好的疗效，并且能够明显改善患者的生活质量和T细胞免疫功能。

The results showed polymeric diaryliodonium salts were effective aryl ion transfer reagents. Thirdly, a new type polymer supported hypervalent iodine reagents poly { [4-Hydroxy iodo] styrene} has been developed. It was an effective oxidative reagent, and could be applied to the one pot synthesis of 4-arylthiazoles.

然后，我们以聚苯乙烯羟基对甲苯磺酰氧基碘苯为原料，成功制备了一类新型聚合物高碘试剂—聚苯乙烯负载的炔基碘盐，并研究了其作为炔基转移试剂的有效性：(1)该试剂可对硫、氮、硒等负离子进行亲电炔基化反应，合成炔基亚砜、0，0-二烃基二硫代磷酸炔基酯、1-苯乙炔基苯并噻唑以及炔基硒醚。

The expression of HIF-1α protein was positively correlated to MVD, lymph node metastasis and perineural invasion, but not with clinical TNM stage.

结论HIF-1α对肿瘤的新血管生成有促进作用，并可促进肿瘤浸润和转移，从而促进肿瘤的恶性进展。

Results MRI findings of nasopharyngeal carcinoma appeared as diffusely or locally thickened nasopharyngeal walls,and pharyngeal recess was closed and pharyngeal opening of auditory tube became shallow or disappeared,sometimes with parapharyngeal space、retropharyngeal space and logus capitis oppressed or invaded.

结果：鼻咽癌的MRI表现为鼻咽壁局限性或弥漫性增厚，咽隐窝闭塞，咽鼓管咽口变浅或消失，可伴有咽旁间隙、咽后间隙、头长肌受压或浸润及颈部淋巴结的转移，可见乳突积液，颅底骨质破坏。
