Objective To evaluate the short -term efficacy and long-term efficacy of thoracic radiotherapy combined with gefitinib in the treatment of elderly patients with advanced non -small cell lung cancer . Methods From October 2012 to October 2015 , 120 elderly patients with advanced non -small cell lung cancer confirmed by histopathology as adenocarcinoma in the Third People's Hospital of Linyi were selected .Using envelope method,the patients were randomly divided into observation group and control group ,with 60 cases in each group .In the observation group ,IMRT was performed on pulmonary lesions ,and 125 mg of gefitinib was also given orally .The control group received IMRT .All patients were followed up , and the short -term efficacy , quality of life and the incidence of side effects in the two groups were observed .Results In terms of short-term efficacy,the RR of the observation group and the control group was 83.3％ vs.50.0％(χ2 =9.16,P=0.001),the disease control rate (DCR) of the observation group and the control group was 100.0％ vs.83.3％(χ2 =6.48,P=0.003),the PD of the observation group and the control group was 16.7％ vs.0.0％(χ2 =8.16, P =0.001 ).At 3 months after radiotherapy,the RR,DCR and PD of the observation group and the control group were 86.7％ vs.50.0％(χ2 =9.86,P=0.001),100.0％ vs.76.7％(χ2 =7.42,P=0.003),23.3％ vs.0.0％(χ2 =11.24,P=0.000).One year after radiotherapy,the RR of the observation group and the control group was 73.3％ vs.33.3％(χ2 =11.16, P=0.000),the DCR of the observation group and the control group was 54.0％vs.60.0％(χ2 =8.48,P=0.001), the PD of the observation group and the control group was 10.0％ vs.40.0％(χ2 =9.48,P=0.001).There was statistically significant difference between the two groups (P<0.05).As to the long-term efficacy,the progression-free survival (PFS) of the observation group and the control group was (17.64 ±1.86) months vs.(13.26 ± 1.82) months (t=7.28,P =0.000);overall survival (OS) was (26.16 ±2.14) months vs.(17.82 ± 2.02) months (t=10.62,P=0.000).The difference was statistically significant (P<0.05).The quality of life of the patients in the observation group was significantly better than that in the control group at 3 months,1 year and 2 years after radiotherapy (P <0.05).There was no statistically significant difference between the two groups in leukopenia,thrombocytopenia, anemia, esophagitis, radiation pneumonitis, gastrointestinal reaction, rash and other adverse reactions(all P >0.05).Conclusion Radiotherapy combined with gefitinib in the treatment of elderly patients with advanced non-small cell lung cancer has better short -term and long-term efficacy ,it can significantly improve the patients ' efficacy and DCR , prolong the patients ' disease PFS time and OS time , improve patients ' quality of life.And did not increase adverse reactions ,it is worthy of clinical application .

Objective To investigate the effects of down-regulation of lemur tyrosine kinase 3 (LMTK3) on the cytobiological behaviors of human lung cancer A549 cells.Methods The expression of LMTK3 in A549 cells was interfered with small hair RNA (shR-NA),and the expression level of LMTK3 was determined by RT-PCR.The effects of LMTK3 on the proliferation,migration,cell cycle and apoptosis of A549 cells were determined by the CCK-8 assay,scratch assay,Transwell assay and flow cytometry,respectively.Results The shLMTK3 cells with stably low expression of LMTK3 and control cells (Scramble) with normal expression of LMTK3 were successfully obtained.The relative proliferation rates of shLMTK3 cells cultured for 24,48 and 72 hours were significantly lower than those in the control cells (0.305 ±0.018 vs 0.354 ±0.011,t =5.24,P＜0.01;0.461 ±0.044 vs 0.551 ±0.027,t =3.91,P ＜0.01;0.74 ± 0.029 vs 0.881 ± 0.028,t =7.70,P ＜ 0.01).The relative migration rate of shLMTK3 cells 24 hours after scratching was significantly lower than that of control cells (0.51 ±0.096 vs 1.00 ± 0.029,t =4.81,P ＜ 0.01).Transwell assay showed that the number of migration cells in shLMTK3 group was significantly less than that in Scramble group (161 ±9.29 vs 308.66 ± 17.60,t =7.42,P ＜ 0.05).The results of flow cytometry showed that shLMTK3 cells were blocked at G1 phase (t =4.35,P ＜ 0.05),and that the inhibition of LMTK3 had no influence on the apoptosis of A549 cells.Conclusion Down-regulation of LMTK3 expression in human lung cancer A549 cells may inhibit the proliferation and migration of A549 cells significantly,indicating that the abnormal expression of LMTK3 in lung carcinoma cells may regulate the biological behaviors and progression of tumors.

270 patients underwent single crown prosthodontics were randomly divided into 3 groups(n =90)and received gingival retraction with single-cord,double-cord and gingival retraction paste respectively.The prosthesis quality of the 3 groups was not statistically significant (P =3.209).The patient satisfaction was more and the gingival retraction time of the paste group was shorter than those of the cord groups(P<0.05).
