Objective:To investigate the effects of siRNA-mediated Plk1 depletion on COS-7 cells and the therapeutic potential of Plk1 in cancer treatment.Methods:Small interfering RNA(siRNA) were used to specifically deplete Plk1 in COS-7 cells.RT-PCR and immol/Lunoblotting analysis were used to verify the inhibitory effect of siRNA against Plk1.Trypan blue exclusion assay and FACS analysis were conducted to determine the effects of Plk1 depletion on the growth and cell cycle profile of COS-7 cells.Results:Synthetic siRNA duplexes against Plk1 were introduced into COS-7 cells,which subsequently resulted in a significant inhibition in Plk1 expression in the cells.Cell growth assay indicated that siRNA-mediated Plk1 depletion significantly inhibited the proliferation of COS-7 cells.FACS analysis revealed that Plk1 depletion caused cell cycle arrest,resulting into large population of sub-G1 cells.Conclusion:siRNA-mediated Plk1 depletion significantly inhibited the proliferation of COS-7 cells suggesting the therapeutic potential of Plk1 in cancer treatment.

Objective:To investigate the expression and significance of NF-?B,and ICAM-1 in laryngeal carcinoma patients.Methods:Two groups of laryngeal carcinoma tissue (one group derived from the laryngeal carcinoma patients;the other from the normal persons) were detected for NF-kappa B P65 protein and ICAM-1′s expressions by immunohistochemistry staining.Results:(1)The expressions of NF-kappa B P65 protein and ICAM-1 of the laryngeal carcinoma patients were much more strengthened than those of the normal persons(P

Objective:To explore the expression and significance of IKK, I?B and NF-?B P65 of NF-? B signal transduction pathway in laryngeal carcinoma patients.Methods:The expression of IKK?, I?B?,NF-?B P65 was examined by immunohistochemical S-P method in laryngeal carcinoma tissues of 40 cases and normal laryngeal tissues of 20 cases.Results:The expression of IKK? and NF-?B P65 in laryngeal carcinoma tissue was higher compared with normal laryngeal tissue,while the expression of I?B? was lower( P

Objective:To discuss how to link the “No. 1 Military Medical Project”hospital network system with the local health insurance system.Methods: To analysis the interface demands of the social health insurance system and the rural cooperative health insurance system. Results: To solve the problem by modify the medical insurance interface program of the out-patient registration and charge, the in-patient registration and charge.Conclusion: the function and requirement has been realized by linking.

Embarking from the people's livelihood science and technology, it is the important direction of new time health work to impel the medicine science and technology to serve the people's livelihood and to develop the people's livelihood. And it is also the request inevitably of the reform of health and medical community institutional. This article discussed the basic content of the people's livelihood science and technology, expounded that the medicine is the important component of the people's livelihood science and technology and has an important position in the development of the people's livelihood science and technology. At the same time, the article analyzed the problems which exist in the service of people's livelihood, of medicine science and technology in the current. And it was proposed that the policy should be reformed and innovated to speeds up the medical science and technology service of people's livelihood.

Objective:To test Jiang Guangrong's(2005)three-dimension model on the depth of counseling process.Methods:In this process-outcome research,28 sessions in a university counseling center were videotaped and coded in terms of the model.Structure Equation Model(SEM)was used to examine the relations between the coding and counselors and clients' evaluation of the session depth.Results:(1)Clients and counselors evaluated differently on the session depth,and clients' evaluation was more positive than counselors' [(4.95±1.12)vs.(4.23±0.94),P<0.05];(2)The model was significantly correlated with counselors' session depth evaluation(path coefficient = 0.55,P<0.01),but not with the clients';(3)The session curves describing each dimension changing over time had different patterns in sessions of different depth level,through which more about the counseling process could be known.Conclusion:The three-dimension model on the depth of counseling process has got some empirical evidences.

Guided by systematic material evaluation theory,the present study assessed textbooks of medical English listening and speaking published over the last 20 years,and conducted a relevant survey to investigate different opinions of the textbooks among teachers and students.It found that cognitive schema theory,information processing theory,the register theory and communicative principle were adopted as guidelines in the compilation.Multi-tasks were utilized to train language skills;medical terminology learning was put great emphasis on;original audio-visual materials were employed.Besides,the majority of the textbooks were compiled based on topics or situations.However,most textbooks of medical English listening and speaking miss the section for cultivating students' autonomous learning,independent thinking as well as phonetic exercise,and they lack the teacher's book and students' book,which should be improved soon.

Objective_To identify the anti-HBV efficiency of AAV-IFNαby infecting HepG2.2.15 cell line, and to develop a new strategy of curing hepatitis B.Methods_Firstly,recombinant vector was packaged into AAV by three plasmids co-transfection method;then AAV-IFNαinfected HepG2.2.15 cell line, and samples were collected on the 1st, 3rd,6th and 9th day;thirdly, The time-course of HBV DNA,HBsAg and HBeAg were detected by qPCR and ELISA.The proliferation of HepG2.2.15 cells detected by MTT.Results_Recombinant AAV-IFNαcan significantly inhibit HBV replication and expression in vitro because of the proliferation of HepG2.2.15 cells inhibited by AAV6-IFNα( P<0.05) .Conclusions_AAV-IFNαis a potential antiviral product for hepatitis B.

Acute promyelocytic leukemia (APL) is a subtype of acute myeloid leukemia,which is rare in children.The treatment of APL mainly includes anthracycline-based chemotherapy,all-trans retinoic acid,and arsenic trioxide,which allow for complete remission,improve the long time survival rate and reduce related toxicity as well.About the optimized treatment,quick breakthroughs have already reached,not only at home in the 80's at the end of the 90's,but also abroad,like National Comprehensive Cancer Network of the United States in 2006-2013.This review summarizes the progress in diagnosis and treatment of children with APL.
