2.How to do ideological education for clinical interns in internet era
Chinese Journal of Medical Education Research 2014;(3):288-290
Clinical practice is a special learning phase. Interns, as both students and doctors are confronted with multiple pressures from studies, employment and examination. Their ideology tends to fluctuate due to the influence of the society. Therefore, it's very important to strengthen the ideo-logical and political education. It is relatively difficult in managing interns due to their dispersed loca-tion and unfixed daily schedule. Internet not only expands the space and time of the ideological edu-cation, but also it has the features of vivid, interesting, timely, open and resource conservation. On the basis of analyzing the characteristics and difficulties of the clinical ideological education and the pros and cons of the network, we proposed the methods to utilize the advantages of network informa-tion technology to enhance the ideological and political education of clinical interns.

Chinese Journal of Nosocomiology 2009;0(18):-
OBJECTIVE To study the lower respiratory tract Acinetobacter baumannii infection in cardiac ICU and its risk factors,in order to take effective control measures. METHODS The risk factors of 5 cases respiratory A. baumannii infection in cardiac ICU of our hospital were investigated. RESULTS Patients with A. baumannii infections were concentrated,accounting for 21.7% at the same period in external cardiac ICU. According to the exposure time among children,the regional distribution and the same kinds of pathogens,the nospital acquired infection was determined as a local outbreak epidemia. The pathogenic microorganism monitoring carried out on ventilator-pipes,hands of health care workers and cardiopulmonary bypass machines etc. A. baumannii was found in tube of warming devices. CONCLUSIONS The in-door distribution and pracedures in cardiac ICU do not meet hygiene requirements,the poor sterile concept among medical staff and bad compliance of hand-washing,and the longterm use of mechanical ventilation,broad-spectrum antibiotics and immunosuppressive agents. All these factors contribute the outbreak of hospital acquired infection.

Academic Journal of Second Military Medical University 2010;31(6):650-652
Objective: To observe the effect of low-dose aspirin on allogeneic chronic allograft nephropathy in renal recipient rats and the possible mechanisms. Methods: Chronic allograft nephropathy model of rats were established and the recipient rats were randomly divided into 2 groups with 10 in each group. Cyclosporine A (5 mg/kg) was administered as a basic treatment one day before surgery to prevent and treat acute rejection. Aspirin therapy group was given oral aspirin (5 mg/kg) daily, and control group were given oral saline 2 ml/d. Animals were sacrificed 8 weeks after operation and the serum creatinine, urea nitrogen levels were determined. Renal histomorphology and immunohistochemistry approaches were used to examine TGF-β1 expression. Results: The severity of pathological lesion, increase of serum creatinine and blood urea nitrogen levels, and expression of fibrosis associated factor TGF-β1 in aspirin therapy group were significantly slighter than those of the saline control group (P<0.05). Conclusion: Low-dose aspirin in addition to routine anti-rejection treatment can be used for treatment of chronic allograft nephropathy in rats, which might be associated with the decreased expression of anticoagulation factor TGF-β1.
