This paper aims to put forward some suggestions on how to deal with the problems about the interface between college English teaching and bilingual teaching,beginning with their definitions,their relationship and the discussion of their present situations.

Most of the current college English term tests do not have an oral test section,which can not effectively and exactly examine students' language ability.Therefore,to better the reactive function of term tests and improve our oral English teaching,it's extremely necessary to include oral test section in.This paper aims to explore the methods of designing college English oral term test,beginning with the related theories and the discussion of its characteristics.Some suggestions are also put forward to help solve the possible difficulties.

Primary central nervous system lymphoma (PCNSL) is a rare extranodal lymphoma. Its pathological type mainly includes dif-fuse large B cell lymphoma. In MRI images, the condition is usually manifested as solitary deep lesions in brain parenchyma, with vari-ous forms of reinforcement. To date, chemotherapy based on high-dose methotrexate administration is the first-line therapy of PCNSL. Combined radiotherapy and chemotherapy can prolong the overall survival of patients. However, this approach simultaneously causes higher incidence of neurotoxicity. High-dose chemotherapy followed by autologous stem cell transplantation is recommended for re-current and refractory PCNSL. Temozolomide and rituximab can be used as treatment options because of their low toxicity and good tolerance. The prognosis of PCNSL depends on several factors, such as serum LDH concentration, age, ECOG/KPS score、cerebro-spi-nal fluid (CSF) protein concentration and tumor location.

Objective To assess the effect of heat shock protein 70 of BCG (BCG HSP70) gene transfection on tumorigenicity and immunogenicity of murine lymphocytic leukemia cells (L1210). Methods BCG HSP70 gene was transfected onto the surface of murine lymphocytic leukemia cells (L1210) by lipofectamine 2000. And then the positive clone (L1210-HSP70) highly expressing HSP70 was selected as the tumor vaccine to study the tumorigenicity experiments in nude mice and syngeneic mice, the therapeutic experiments, and the immunoprotective effects. Results The expression of BCG HSP70 on the L1210 cells surface was detected, and the L1210-HSP70 cells had the same tumorigenicity as the parental L1210 cells did. Tumorigenicity experiments in syngeneic mice:In L1210-HSP70 group, tumor growth was slow or without the formation of tumor. As compared with L1210 group and L1210-neo group the mice survival time was signiifcantly prolonged, showing a marked stimulating effect on L1210 specific Th1 cells,. Tumor-bearing mice showed complete coagulation necrosis and abundant CD8+T lymphocyte inifltration (P<0.05). The tumor vaccine of L1210-HSP70 cells had the antitumor therapeutic efifcacy and immune protection effect, demonstrating that the tumor growth was signiifcantly inhibited, tumor diameter was markedly reduced and the survival time of tumor-bearing DBA/2 mice was further prolonged. Conclusions BCG HSP70 gene transfection could effectively improve the immunogenicity of tumor cells, activate speciifc T cells and enhance the anti-tumor immunity in vivo. Meanwhile, the host anti-tumor immunity could be enhanced.

Objective To investigate the clinic application significance of hand control high frequency continuous positive airway pressure treatment with self-inflating bags(SIB) fitted with positive end expiratory pressure (PEEP) valves on the neonatal transport of severe neonatal congenital diaphragmatic hemia (CDH).Methods Clinical data of a total of 28 infants with severe CDH transported by the pre-hospital emergency care team of our department were analyzed.The 28 patients were divided into treatment group (n =16) and control group (n =12).Hand control high frequency continuous positive airway pressure of SIB and PEEP valve were administered in the treatment group,while only hand control SIB positive airway pressure were given in the control group during the transportation.The exacerbation,complication and blood gas indicators at different time before and after treatment in two groups were monitored and compared.Results In the treatment group,no case aggravated,no case complicated with gas leakage,pulmonary hemorrhage,persistent pulmonary hypertension,intracranial hemorrhage; 2 cases died for multiple organ failure before operation (12.5％),5 cases died after operation (31.3％).In the control group,8 cases aggravated (66.7％),cases complicated with gas leakage,pulmonary hemorrhage,persistent pulmonary hypertension,intracranial hemorrhage were 5 (41.7 ％),3 (25.0％),1 (8.3 ％),respectively; 4 cases died for multiple organ failure before operation (41.7％),5 cases died after operation (33.3％).The indexes of pH,PaO2,PaCO2 and PaO2/FiO2 at different time before and after treatment between the treatment group and the control group or in each separate group all showed statistical significance (P ＜ 0.05).Conclusion Early accurate diagnosis during transportation with hand control high frequency continuous positive airway pressure of SIB fitted with PEEP valves for CDH is a safe and effective ventilation method which can reduce complications and increase successful transfer and survival rate.
