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.

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 .

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.

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 investigate the interaction of in vitro antibacterial activity between cefoperazone-sulbactam and imipenem against carbapenem-resistant Acinetobacterbaumannii.Methods The minimum inhibitory concentrations (MIC) of imipenem and cefoperazone-sulbactam against Acinetobacter baumannii were detected and the fractional inhibitory concentration (FIC) index of imipenem/cefoperazone-sulbactam combination was calculated by broth micro-dilution method.The interactions of imipenem and cefoperazone-sulbactam were assayed by K-B agar plate method.Results The MIC50 of cefoperazone-sulbactam and imipenem were both 16 mg/L,and MIC90 of the two drugs were both 64 mg/L.Among the 26 strains of Acinetobacter baumannii,16 strains had FIC indexes ≤0.5,and 10 had FIC indexes≥2.0.K-B agar plate assay showed that the cefoperazone-sulbactam/imipenem combination was synergistic for strains with FIC indexes≤0.5,and antagonistic for strains with FIC indexes ≥ 2.0.Conclusions Imipenem in combination with cefoperazone-sulbactam can be either antagonistic or synergistic against carbapenem-resistant Acinetobacter baumannii.The clinical use of cefoperazone-sulbactam/imipenem combination for the treatment of carbapenem resistance Acinetobacter baumannii infections should be cautious in case of antagonism.

With high morbidity and mortality,nosocomial bacterial meningitis(NBM)is a kind of serious nosocomial infection.Post-neurosurgical patients are at a high risk of this infection andNBM in-creases hospital stay and medical expense obviously.In this article,we reviewed recent studiesonpathogen-esis,treatment,and research progress of NBM in neurosurgical patients,and presented unresolved ques-tions and research direction in the future.

Objective To research the effect of type 2 diabetes on collagen content in different organsinOLETFrats.Methods 24maleOLETFratsweregivenhigh‐caloriedietfor30weekstoset up the T2DM. At the 30th week ,16 male T2DM OLETF rats were selected as case group ,and 12 LETO rats were used as control group. The skin ,liver ,and femur tissue were collected at the same time. HE and Masson staining and immunohistochemical test were performed to measure the content of collagen and HPLC was used to detect hydroxyproline. Results Compared with the NC group ,DM group showed the collagen fibers were decreased in femoral and skin tissue ,but increased in liver tissue. The collagen content of the skin tissue was significantly lower in DM group than in NC group [(149.9 ± 18.4) vs (266.0 ± 54.8)mg/g ,P<0.01] ,and the collagen content of the femur tissue was also lower in DM group than in NC group [(185.60 ± 19.38) vs (243.27 ± 22.19)mg/g ,P<0.05]. In contrary ,the collagen content of liver tissue was higher in DM group than in NC group [(134.54 ± 18.78) vs (64.52 ± 21.51) mg/g ,P<0.01]. Conclusion The effect of type 2 diabetes on the collagen in different organs is different. The collagen content decreases in the femoral and skin tissue but increases in the liver.
