Objective To comparative analysis the effect of radiotherapy,thermoradiotherapy and chemora-diotherapy on esophageal cancer.Methods 120 patients with esophageal carcinoma were selected and randomly divided into the radiotherapy group,thermoradiotherapy groupand chemoradiotherapy group by digital table method, with 40 cases in each group,which were treated with radiotherapy alone,thermoradiotherapy alone and radiotherapy combine with chemotherapy respectively.The effects of treatment of the three groups were compared.Results The main toxic reaction in the three groups during the treatment for adverse reaction were digestive system reaction,hema-tologic toxicities and radioactive esophagitis.The incidence of toxic reaction of the three groups were not statistically significant(P >0.05).Total response rate of simple radiotherapy group,the thermal radiation group,chemoradiothera-py group were 52.5%,75.0% and 85.0%.,The total remission rate of chemotherapy group was higher than those of the radiotherapy group and the thermal radiation group(χ2 =5.218,3.857,all P <0.05).Conclusion The different treatment methods of esophageal cancer can obtain certain curative effect,but there are some adverse reactions.Among different treatment methods,radiotherapy and chemotherapy in the treatment of esophageal carcinoma can get better effect than the radiotherapy and chemoradiotherapy.

Objective To explore the expression of circ_0006692 in NSCLC and its relation with clinicopathological characteristics and related mechanism. Methods We collected 50 pairs of NSCLC tissues and adjacent tissues. The expression of circ_0006692 was detected by qRT-PCR and its relation with clinicopathological features was analyzed. We constructed lung cancer A549 cell line with circ_0006692 overexpression and knockdown. Cell proliferation, migration and invasion were detected by MTS, colony forming, wound healing and Transwell invasion assays. qRT-PCR and Western blot were used to detect the effect of circ_0006692 expression change on EMT-related gene expression. Results The expression of circ_0006692 in NSCLC was significantly higher than that in adjacent tissues (
