Objective To evaluate the efficacy of different anaplastic lymphoma kinase(ALK)inhibitors combined with anlotinib in the treatment of non-small cell lung cancer(NSCLC).Methods Clinical data of drug resistant NSCLC patients with ALK positive mutation was collected who were treated with ALK inhibitors and anlotinib synchronously.According to different regimens,three groups were set,alectinib+anlotinib,ceritinib+anlotinib,and crizotinib+anlotinib.The latest imageological examination results of the patient before the synchronous therapy was set as the baseline to evaluate the therapeutic effect according to Recist1.1.The event free survival(EFS)of each group was calculated with disease progression,patient death,treatment discontinuation and changing regimen as endpoints.Data of tumor markers,hematology test,liver function,cardiac function,renal function biochemical examination was collected and analyzed statistically before and after the combination therapy,with P<0.05 as the statistically significant difference.Results After screening,clinical data of 49 patients were collected.Twenty-three patients in the alectinib+anlotinib group,with a disease control rate(DCR) of 86.96%;mean EFS was(10.8±3.6)months,median EFS of 8.3 months;14 patients in the ceritinib+anlotinib group,with a DCR of 71.43%,mean EFS was(6.5±2.9)months,median EFS was 5.6 months;12 patients in the crizotinib+anlotinib group,with a DCR of 66.67%,mean EFS was(7.7±3.2)months,median EFS was 7.2 months.EFS of alectinib+anlotinib group was longer significantly than the other two groups(P<0.05).Only CyFra21-1,increased significantly after the combination of crizotinib and anlotinib(P<0.05).No statistically significant difference in biochemical test and hematology test before and after the treatment(P>0.05).Conclusions The therapeutic effect of ALK inhibitors with anlotinib was ordered,alectinib being the most effective,followed by ceritinib and finally crizotinib.The combination of ALK inhibitors with anlotinib did not cause any abnormal results in the examination of heart,liver,kidney and blood cells.
目的 探讨多梳蛋白SUZ12对肝细胞肝癌(HCC)细胞增殖、血管生成拟态形成和人脐静脉内皮细胞(HUVECs)血管生成的影响。方法 分别利用MTT比色法及体外血管生成实验检测SUZ12表达水平改变对HCC细胞SMMC-7721、Hep3B增殖、血管生成拟态形成和HUVECs血管生成的影响。结果 MTT结果显示,在HCC细胞中分别敲低或过表达SUZ12均对HCC细胞的增殖能力无明显影响。将SUZ12低表达HCC细胞与HUVECs共培养后,HCC细胞的血管生成拟态管样结构形成增多。此外,将SUZ12敲低组HCC细胞的培养上清用于培养HUVECs后,HUVECs的血管生成拟态管样结构形成也明显增多。结论 SUZ12对HCC细胞的增殖无影响,其在HCC中可抑制HCC细胞和HUVECs的血管生成拟态管样结构形成。上述结果提示SUZ12可能通过调控HCC细胞及HUVECs的血管生成发挥抑癌作用。
Objective To investigate the effects of SUZ12 on cell proliferation of hepatocellular carcinoma(HCC),vasculogenic mimicry formation and human umbilical vein endothelial cells(HUVECs)angiogenesis.Methods MTT assay was performed to detect the proliferation of SMMC-7721 and Hep3B cells.The effects of SUZ12 on the angiogenesis of HCC cells and HUVECs cells were studied by in vitro angiogenesis experiment.Results The result of MTT assay showed that SUZ12 knockdown or overexpression in HCC cells had no significant effect on the proliferation of HCC cells.We found that when HCC cells with low SUZ12 expression were co-cultured with HUVECs cells,the formation of vasculogenic mimicry tubular structures in HCC cells increased.In addition,we also found that after the culture supernatant of HCC cells in the SUZ12 knockdown group was used to culture HUVECs cells,the formation of vasculogenic mimicry tubular structures in HUVECs cells also increased significantly.Conclusions SUZ12 has no effect on the proliferation of HCC cells,but it can inhibit the formation of vasculogenic mimicry tubular structures in HCC cells and HUVECs cells.These results suggest that SUZ12 plays a role in cancer inhibition by regulating the angiogenesis of HCCcells and HUVECs cells.
