Objective:To investigate the relationship of the changes of peripheral bloos T cell subsets and NK cell with non-Hodgkin's lymphoma(NHL).And to investigate the change of the cell immune function of NHL and chronic lymphadenitis.Methods:Peripheral blood T cell subsets,NK cell with NHL,chronic lymphadenitis patients and 50 normal controls were detected quantitatively with FCM.Results:Compared with the normal controls,the number of CD3~+,CD4~+T cell,CD4~+/CD8~+ ratio markedly reduced,while those of CD8~+T cells increased.These were no significant changes in NK cell.Compared with the group of chrnic lymphadenitis,the number of CD8~+T cell,NK cell markedly increased,while these were no significant changes in CD3~+,CD4~+T cell and reduction of CD4~+/CD8~+ ratio.Conclusion:NHL patients cell function was suppressed.The detection of T cell subsets and NK cells are clinically valuble on the diagnosis,treatment and prognosis of NHL.
4.Experimental study on the viscoelasticity of aorta ascendens.
Journal of Biomedical Engineering 2003;20(1):38-40
We carried out the stress relaxation and creep experiments on the aorta ascendens of five fresh dead bodies of normal chinese men who had died from impetuous trauma on the head. The stress relaxation and creep data and curves of the aorta ascendens were obtained. Then regression analysis was performed to get the reduced stress relaxation and creep functions. Finally, we analyzed and discussed the results of the experiment.

Objective On the background of the clinical skills competition for national medi-cal students in the higher medical colleges and universities, to investigate medical students' mastery of hand hygiene knowledge and skills, explore the effective methods of teaching, and improve the medical students' hand hygiene compliance and accuracy in clinical practice. Methods 90 medical students at a tertiary-level teaching hospital clinical practice stage were randomly selected for the study, and performed hand hygiene theoretical knowledge and practical skills training in special education. Special teaching investigation was made before and after training, to investigate the students' hand hygiene compliance rate in clinical practice. And the correct rate of hand hygiene were examined and medical students' hand hygiene compliance rate and correct rate were compared before and after the special teaching and training. Statistical analysis was made by using chi square test 2. Results After theory teaching and additional special skills training the students' hand hygiene compliance and accuracy were improved significantly (79.00%vs. 35.50%, P=0.000). The correct rate of hand hygiene was also significantly higher than before training (92.22% vs. 61.11%, P=0.000). Conclusion Hand hygiene knowledge and skills training can significantly improve the medical students' hand hygiene compliance and accuracy in the clinical practice, and is conducive to the prevention of the spread of infection in hospitals, and then reduce the incidence of hospital infection.

In accordance with the General Hospital Accreditation Standards Ⅲ (2011) and other HAI-related hospital guidelines,a quantitative assessment index system for infection control of general hospitals has been established.Based on these,departmental performance of the hospital has been regularly checked in their infection control,and the outcomes of assessment included into the performance appraisal system of the hospital.Thanks to this practice,there have been no outbreaks of hospital associated infections in the hospital in recent two years,the incidence of hospital associated infection decreased from 1.25% in 2012 to 1.05% in 2013.Proper hand hygiene rates,compliance rates increased from 45.3% and 26.9 % in 2012 to 92.4 %and 65.5 % in 2013.The index system for evaluating prevention and control of hospital associated infection is scientific and effective.

Objective To explore the investigation and control method for the epidemic of surgical site infection (SSI)in a hospital.Methods Data of orthopedics patients receiving clean wound orthopedics operation were ana-lyzed retrospectively,and effective measures were taken to control the epidemic of HAI.Results From June to August 2012,a total of 312 patients received clean wound orthopedics operation,7 (2.24%)SSI cases occurred.SSI rates during the same period from 2009 to 2012 were significantly different(P <0.05),and was the highest in 2012. HAI management staff reviewed patients’medical records,communicated with staff in orthopedics department,and put forward advice for SSI control;orthopedics department worked out and implemented detailed infection control measures.The subsequent surveillance showed that the prevalence of SSI in orthopedics ward decreased to 0.38%, infection outbreak was effectively controlled.Conclusion HAI management department played an important role in the finding and control of HAI outbreak.Scientific analysis on monitored data and proper measures adopted by HAI management department and clinical department can effectively control HAI outbreak.
