空洞型非小细胞肺癌的预后分析

Objective To explore the survival and prognostic status of the cavitating non-small cell lung cancer. Methods A total 42 surgically treated patients with cavitating non-small cell lung cancer were studied retrospectively. Kaplan-Meiei was used to analyze the relationship between the prognostic factors and survival time. The cavitaing non-small cell lung cancer were matched 1:2 to the patients with non-small cell lung cancer that there is no cavity in X-ray, for gender, age, histology, lymph nodes dissection, stage, and whether receiving chemotherapy. The two groups were compared using the Log-rank test. Results The overall 1, 3, 5- year- survival rates for cavitating non-small cell lung cancer were 76.2%, 28.6%, and 14.7%, respectively. The diameter of the cavity and lymph nodes status significantly influenced syrvivals. 1he overall syrvival between the two groups of patients showed no sig- nificant differences (P=0.075). But the factors of women(P=O.040), younger than 60 years(P =0.032), NO of the lymph nodes dissection group(P=0.046), and staging Ⅰ were significantly influenced 5-year survivals(P=0.048). Conclusion The diameter of the cavity and lymph nodes status were correlated with the survival. The carcinomatous cavity are important prognosis factors for the nan-retail cell lung cancer patients of younger than 60 years, negative of lymph nodes dissection and staging Ⅰ , but whether the carci- nomtous cavity are important prognosis factors for the non-small cell lung cancer patients of woman was not determined.

lncRNA Meg3在全反式维甲酸和转化生长因子β3影响小鼠腭突间充质细胞增殖过程中的作用

目的:探索长链非编码RNA(lncRNA)Meg3在全反式维甲酸(atRA)和转化生长因子β3(TGF-β3)影响胎鼠腭突间充质细胞增殖过程中的作用。方法:分离、培养妊娠13 d胎鼠腭突间充质细胞。EdU法检测对照组(未处理)、atRA组(5μmol/L atRA)和TGF-β3组(10μg/L TGF-β3)处理48 h腭突间充质细胞增殖能力的变化。荧光原位杂交和实时荧光定量PCR法检测上述3组Meg3的定位和相对表达量。利用EdU实验检测Meg3 siRNA转染前后atRA和TGF-β3对腭突间充质细胞增殖的影响。结果:与对照组相比,atRA处理48 h可抑制腭突间充质细胞的增殖,TGF-β3处理48 h可促进腭突间充质细胞增殖(P<0.05)。与对照组相比,atRA可促进腭突间充质细胞中Meg3的表达,TGF-β3可抑制Meg3的表达(P<0.05)。Meg3基因沉默后,与对照组相比,Meg3 siRNA组、atRA和TGF-β3处理组胎鼠腭突间充质细胞增殖能力均增强(P<0.05)。结论:atRA对胎鼠腭突间充质细胞的增殖抑制作用可能主要通过Meg3介导,而T...
