Objective To study the expressive levels of galectin-3(gal-3) and sambucus nigra agglutinin (SNA) and their clinicopathological significance in the benign and malignant lesions of stomach. Methods EnVisonTM immunohistochemistry for assaying gal-3 expressive level and ABC cytochemistry for determining SNA expressive level were used in conventional paraffin-embedded sections from specimens of gastric cancer(n=49), peritumoral tissues(n=20), metastastic foci of lymph nodes(n=36), and different types of benign lesions(n=80). Results The positive rates of gal-3 and SNA were significantly higher in gastric cancer tissues than those in peritumoral tissues and different types of benign lesions (P<0.05, P<0.01). The positive cases of gal-3 and/or SNA in peritumoral tissues and benign lesions showed mild- to severe-atypical hyperplasia of mucous epithelial cells. No difference was found between the primary foci and metastatic foci in gal-3 and SNA expressions (P>0.05). The positive rates of gal-3 and SNA were significantly lower in histologic grade Ⅱ, infitrating depth T1,T2 and no-metastasis of regional lymph node than those in histologic grade Ⅲ, Ⅳ, infitrating depth T3,T4 and metastasis of lymph node in gastric cancer(P<0.05). The positive rates of gal-3 and SNA were higher in lymphnede metastatic site N1 and no-metastasis of distant organs than those in lymphnede metastatic site N2, N3 and metastasis of distant organs, but no significant difference was found (P>0.05). The consistence was found between the expression of gal-3 and SNA in gastric cancer tissues (χ2=6.59,P<0.05). Conclusions The expressive levels of gal-3 and SNA may be important molecular markers of lectins for reflecting the carcinogenesis, progression and biological behaviors in gastric cancer. 相似文献

目的探讨短程5-FU/CF方案新辅助化疗对结直肠癌细胞凋亡、增殖和p53表达以及术后并发症和预后的影响。方法分别采用脱氧核糖核苷酸末端转移酶介导的缺口末端标记法(TUNEL)和免疫组化SP法检测68例患者结直肠癌组织的细胞凋亡指数(AI)和ki-67增殖指数(PI)及凋亡相关基因p53的表达,并比较新辅助化疗组和对照组患者术后并发症的发生情况和预后情况。结果新辅助化疗组肿瘤细胞的AI均数为3.56%,明高于对照组的2.29%(P〈0.01),PI均数为22.60%明显低于对照组的33.60%(P〈0.01),p53阳性表达率为28.9%(11/38)明显低于对照组的56.7%(17/30)(P〈0.05)。两组中大肠癌细胞的AI与PI均呈负相关(r=-0.790,r=-0.663)(P〈0.01)。两组术后并发症的发生差异无显著性(P〈0.05)。两组的复发转移率和复发转移平均时间差异有显著性(P〈0.05)。结论短程5-FU/CF方案新辅助化疗可以显著诱导结直肠癌细胞凋亡,并抑制其增殖;降低结直肠癌组织p53的阳性表达率,而不增加术后并发症的发生,能延缓和减少结直肠癌术后的复发转移。 相似文献
