Epidermal growth factor receptor(EGFR) family plays an important role in the development of gastric cancer. EGFR-targeted therapeutic agents include extracellular monoclonal antibodies and intracellular tyrosine kinase inhibitors. Many new agents such as trastuzumab, cetuximab, panitumumab and lapatinib, have been tested in randomized phase Ⅲ clinical trials. Results from ToGA trial may shed some light on the treatment of advanced gastric cancer.

Tumor progression is often associated with immune suppression or the ability of the tumors to avoid immune surveillance.Immunotherapy improves the ability of the immune system to recognize and clear tumor cells with a little influence on the normal tissues.Immunotherapy is a hot spot in the research of advanced esophageal cancer.Innnunotherapy of esophageal cancer includes immune checkpoint inhibitors,adoptive cellular immunotherapy,tumor vaccines and antibody therapy.At present,a large number of clinical trials are underway to evaluate the role of immunotherapy in esophageal cancer.Checkpoint inhibitors represented by Pembrolizumab and Nivolumab,has achieved initial success in the treatment of advanced esophageal cancer to improve the prognosis and life quality of esophageal cancer patients.In the future,further studies are needed to have a research on the effects of tumor heterogeneity,prediction of therapeutic targets,and immune tolerance.

Objective:To study the effect of exogenous hyaluronidase on proliferation of human breast cancer cells in vitro.Methods:The proliferation of human breast cancer cell line ZR-75-30 were detected by MTT-assay and flow cytometry.Results:The absorbency value(A) of ZR-75-30 in study group treated with Hyase (0.674?0.221) was significantly higher than that in control group(0.563?0.046).The percentage of phase S cells in study group(18.36?0.65) was higher than that in control group(2.19?0.10);the percentage of phase G0/G1 cells in study group(44.49?4.33) was lower than that in control group(62.14?26.97).The absorbency value(A) of MDA-MB-435 in study group (0.674?0.221) was significantly higher than that in control group(0.563?0.046).The absorbency valve(A) of MDA-MB-231 in study group (0.674?0.221) was significantly higher than that in control group(0.563?0.046).Conclusion:Exogenous hyaluronidase may promote the proliferation of breast cancer cell lines in vitro.

Objective To study of vascular false as the clinical effect and safety of acromastitis were treated by com -pound anisodine treatment , to provide reference for the treatment of vascular pseudo optic .Methods From June 2013 to June 2015, 132 cases of patients with vascular pseudo optic papilla in our hospital were selected as the observation objects , and were divided into observation group and control group each 66 cases according to the treatment method .The control group was treated with routine drug therapy , and the observation group in the control group on the basis of daily injections of Com -pound Anisodine Hydrobromide Injection .Two groups before and after the treatment of vision changes , and the treatment of safety and efficacy were compared .Results The curative effect:The two groups of patients after treatment were improved , but the observation group was significantly higher than the control group after treatment ;The cure rate and total effective rate of the observation group were 39.51%and 88.89%respectively, which was significantly higher than the control group of 24. 36%and 73.08%, and had better curative effect in observation group .Security aspect:The total incidence of adverse reac-tions in the observation group and the treatment group was 10.61%, significantly less than 24.24% of the control group, higher safety .Conclusion In the treatment of vascular pseudoaneurysms as papillitis drugs , the curative effect of compound anisodine is much better with better security , which can significantly improve the visual acuity of the patients .

The brain computer interface (BCI) can be used to control external devices directly through electroencephalogram (EEG) information. A multi-linear principal component analysis (MPCA) framework was used for the limitations of tensor form of multichannel EEG signals processing based on traditional principal component analysis (PCA) and two-dimensional principal component analysis (2DPCA). Based on MPCA, we used the projection of tensor-matrix to achieve the goal of dimensionality reduction and features exaction. Then we used the Fisher linear classifier to classify the features. Furthermore, we used this novel method on the BCI competition II dataset 4 and BCI competition N dataset 3 in the experiment. The second-order tensor representation of time-space EEG data and the third-order tensor representation of time-space-frequency BEG data were used. The best results that were superior to those from other dimensionality reduction methods were obtained by much debugging on parameter P and testQ. For two-order tensor, the highest accuracy rates could be achieved as 81.0% and 40.1%, and for three-order tensor, the highest accuracy rates were 76.0% and 43.5%, respectively.

Objective To identify the molecular characteristics on nucleotide and amino acid in E gene through the comparative analysis of differences between genotype 3 Japanese encephalitis virus(JEV)in China and the live attenuated vaccine(SA14-14-2).Methods Obtained the E gene nucleotide sequence of Japanese encephalitis virus from GenBank.Multiple alignment and amino acid(AA)analysis were carried out by Clustal X(1.81),DNAStar and GENEDOC(3.2).According to the ribbon diagram of the E protein structure based on the model of the soluble fragment of tick-borne encephalitis virus(TBEV)as a template for Japanese encephalitis virus E protein amino acid sequence analysis.Results Compared different regions and different host genotype 3 JEV with SA14-14-2 the nucleotide sequence homology was,up 96%and 95% and the amino acid homology was up 95%and 94%,respectively.The nucleotide and amino acid homology was higher among the same area and the same host.Ten common amino acid variations and five special variations(E160 in domain Ⅰ,E123 and E227 in domain Ⅱ,E441 and E487 in non-structural domain)were found between genotype 3 JEV and SA14-14-2.Conclusion The homology in E gene was higher between genotype 3 JEV in China and SA14-14-2.Five special amino acid differences were found in genotype 3 JEV.The existing live attenuated vaccine strain is theoretically possible to protect genotype 3 JEV in China.
