1.Expression,identification and purification of the resuscitation-promoting factor B of Mycobacterium tuberculosis
Journal of Chongqing Medical University 1986;0(03):-
Objective:To construct the Resuscitation-promoting factor B(RpfB)expression plasmid of Mycobacterium tuberculosis, and express and purify it in E.coli.Methods:RpfB gene of Mycobacterium tuberculosis was amplified with PCR method from the H37Rv,cloned into pET32a(+)vector,and then transformed into E.coli Top10.After identifying by restriction digestion and DNA sequencing,the constructed recombinant plasmid was transformed into E.coli BL21,and expressed the recombinant protein under the control initiated by T7 after induction with IPTG.The target protein was identified by Western-blot and purified by using affinity chromatograghy.Results:The size of the RpfB gene digestedby restricted enzymes accorded with the theoretical size and the DNA sequence with the reported one in literatures.61KDa protein was found by SDS-PAGE and Western-blot.Conclusion:The recombinant expression plasmid pET32a(+)-RpfBv of RpfB gene was successfully cloned and constructed,and the recombinant protein with high purity was obteined;which laid the basis for further study.

Objective:To construct the Resuscitation-promoting factor A(RpfA) expression plasmid of Mycobacterium tuberculosis, and express and purify it in E.coli.Methods:RpfAgene of Mycobaeterium tuberculosis was amplified with PCR method from the H37Rv,cloned into pET32a(+) vector,and then transformed into E.coli Top10.After identifying by restriction digestion and DNA sequencing,the constructed recombinant plasmid was transformed into E.coli BL21,and expressed the recombinant protein under the control initiated by T7 after induction with IPTG.The target protein was identified by His-tag in-gel Stain and purified by using affinity chromatograghy.Results:The size of the RpfA gene digested by restricted enzymes accorded with the theoretical size and the DNA sequence with the reported one in literatures.66ku protein was found by SDS-PAGE and His-tag in-gel Stain.Conclusion:The recombinant expression plasmid pET32a(+)-RpfA was successfully cloned and constructed, and the recombinant protein with high purity was obteined;which laid the basis for further study.
4.Factors of Nosocomial Infection of 1014 Disabled Children
Chinese Journal of Rehabilitation Theory and Practice 2006;12(2):162-163
ObjectiveTo explore the causation of nosocomial infection in disabled children.MethodsThe causation of nosocomial infection in disabled children (n=1014) was analyzed retrospectively. The relationship between nosocomial infection and the factors, such as constituent ration in the infections parts, time in hospital, age and contact history separately were analyzed.ResultsOut of the 1014 patients, 291 cases were infected (the rate was 29%). The main site was in the respiratory system (276 cases, 94.8%). Among that, 73.2 % in upper respiratory tract and 21.6% in lower respiratory tract. The infection of digestive canal was only 7.6 %. The nosocomial infection rate in children under 1, 1~3, and above 3 years old were 44.6%, 37.8% and 27.5% respectively. The rate of those with contagious contact history was 31.6%, significantly higher than the ones without contact history (9.1%) (P≤0.05). There was no significant difference between infection rate and the time in hospital.ConclusionThe nosocomial infection is related to the age, contagious contact history, hospital environment and body nutritional situation, but not with time in hospital.
5.Design of an overall health and epidemic protection system during joint operations
Military Medical Sciences 2014;(10):762-764
This paper focuses on the requirements of joint operations under informationization in the future,and system-atically analyzes the characteristics of medical protection with regard to epidemic causes and surveillance,prevention meas-ures,mental health,and nuclear,chemical and biological protection.This paper elaborates on the basic principles of medical protection and raise proposals about health and epidemic protection so as to provide references for health support of PLA during joint operations.

seventy) years old) with lung infections were equally divided into two groups:cefoperazone/sulbactam group and cefoperazone group in a regimen of 1.0-2.0 g,twice daily for 5-14 days.RESULTS The effective rate of both agents were 100% and 80%,and their ADRs incidence rate of elderly was 4.98% and 25.00%, respectively.There were statistically significant difference(P(
7.Role of FOXP3 in tumor immunity
Academic Journal of Second Military Medical University 2001;0(09):-
FOXP3,a member of the forkhead/winged-helix family,exerts its immunosupression effect by regulating the development,differentiation and maturation of CD4+ CD25+ regulatory T cells(Treg).Treg plays an important role in immune escape mechanism in oncology research.This article reviews the expression of FOXP3 in various types of tumors and its role in tumor immunology and immunotherapy.
8.Analysis and Design of Database for Electronic Medical Tag Information System
Chinese Medical Equipment Journal 1989;0(04):-
Objective To accomplish the requirement analysis and design of database for electronic medical tag information system. Methods According to the principle and requirement of information engineering methodology, the operation requirement and data requirement were analyzed, and the database was designed including its concept, logic and physics models. Results The thought and method of electronic medical tag information database were proposed. Conclusion A basic data platform is established for casualties' information collection, storage, transmission, exchange and utilization in wartime.
9.Comparison of the Effectiveness between Hospital-card and Traditional Payment Mode
Modern Hospital 2016;16(1):127-128,131
Objective To provide reference for optimizing the procedure of service to patients by comparing the effectiveness between the two payment modes.Methods 497 patients were divided into the experimental group and the control group, and key indexes from the two groups was comparatively analyzed.Result There is no statisti-cally significant in payment complexity between the two groups(P<0.05).However, the effectiveness of mode trans-formation in the experimental group was dramatically higher than that in the control group, which has statistically sig-nificance ( P<0.05) .Conclusion The experimental group of mode transformation has a remarkably higher effec-tiveness than that in the control group, and thus it is worthy of promotion and application.
