Objective To patient who suffer from middle and late period carcinoma of esophagus radiation therapy and chemotherapy. Observe the effects and the side effects of radiation therapy and chemotherapy.Methods Radiation therapy and chemotherapy 60 examples and radiation therapy 60 examples,radiation use usually divide,DT 40 Gy reduce area of radiation therapy,aroid medulla,add DT 20～30 Gy,its finished after 6～7 weeks.radiation therapy and chemotherapy after 1 and 4 week,DDP 20 mg/d is used.CF 0.1/d ivgtt CF ivgtt 1/2 is used use 5-fu 500 mg/d.iv five days in a routine,every day use radiation therapy and chemotherapy.Results Radiation therapy and chemotherapy 1,2,3 year alive rate are 67%,46%,34%,radiation therapy 1,2,3 year alive rate are 52%,38%,24%,pneumonia of radiation therapy is 14 examples and 12 examples,leukocyte in blood reaction is 26 examples and 17 examples,gastrointestinal effective is 25examples and 9 examples,death is 38 examples and 48 examples,treatment routine is better than compare routine (P＜0.05).Conclusion Radiation with PCF plan chemotherapy treat middle and late period carcinoma of esophagus have hish alive rate side effects and bad effects are low.

AIM: To investigate the effect of liquorice extract on TGF-β1-induced myocardial fibroblast (CFs) fibrosis. METHODS: 10 ng/mL TGF-β1 induced CFs to establish myocardial fibrosis cell model. Fibrotic cells were treated with liquorice extract and the cell activity was detected by MTT assay. CCK-8 was used to detect the effect of liquorice extract on CFs proliferation. The expression of smooth muscle actin (α-SMA) was detected by immunofluorescence. Western blot was used to detect TGF-β1/Smad signaling pathway related proteins and p-Smad2, p-Smad3 expression levels. The mRNA expression levels of Smad2, Smad3 and Smad4 were detected by RT-PCR. RESULTS: Compared with the control group, there were statistically significant differences in cell activity (P<0.05). The cell proliferation rate of glycyrrhiza uralensis extract groups was significantly lower than that of TGF-β1 group (P<0.05). The expression levels of α-SMA and TGF-β1/Smad signaling pathway related proteins in 100 μg/mL liquorice extract were significantly lower than those in TGF-β1 group (P<0.05). CONCLUSION: Glycyrrhiza extract can improve the occurrence and development of TGF-β1-induced myocardial fibrosis, and its mechanism maybe related to the inhibition of TGF-β1/Smad signaling pathway.
