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 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.

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 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 .

OBJECTIVE： To observe the stability of mezlocillin sodium in 5％ glucose injection， glucose and sodium chloride injection and maintain solution for infants injection with different pH， over different periods and at 4℃ ， 25℃ ， 37℃ .METHODS： 9 solutions with different pH were made up by mezlocillin sodium and above-mentioned infusion fluids， according to 4 factors and 3 levels to make L9（34） orthogonal test.Then determination of mezlocillin sodium in each solution was carried out with ultraviolet spectrophotometry.RESULTS： The contents of mezlocillin sodium in above-mentioned solutions with different pH and at different temperature have not changed obviously over 0h-8h.CONCLUSION： Mezlocillin sodium is compatible with above-mentioned solutions.

The pathogenesis of obesity in children is unclear.Genetic play an important role,including gene mutations,polymorphisms,epigenetics.And the other hand,environment factors such as intrauterine environment,nutrition,physical exercise,and gut microflora also affect the obesity.The genetic and environment factors have interaction,leading to the occurrence of childhood obesity and development.With the advances in molecular biology techniques and large-scale,large sample size of population screening,new obesity-related genes,single nucleotide polymorphisms,the apparent genetic markers will continue to be found,looking forward to the future predict obesity,to choose to guide effective treatment,or even contribute to the development of genetic targeting drugs.

The contributions of the three winners (L Hartwell, RT Hunt and PM Nurse) of the 2001 Nobel Prize for physiology or medicine revealed the mystical veil of cell cycle control. It was of far-reaching significance for exploring new method for cancer treatment. It will also give a good deal of enlightenment to the basic research of traditional Chinese medicine. Their understanding about the cause and development of cancers changed from the static view to dynamic dialectical analysis, from simplex study to comprehensive analysis; they stressed regulation, instead of killing in the treatment of cancer; and they thought that the numerous factors driving the normal process of the cell cycle could be summarized as positive and negative factors. These opinions were similar to some theories of traditional Chinese medicine, such as treatment based on syndrome differentiation, integrative treatment, and keeping the balance between yin and yang, and established a connection between traditional Chinese medicine and the western medicine, which would further widen the research on compound prescriptions of Chinese herbs.

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.
