ABSTRACT
At present, the teaching management department is facing a big puzzle in the education of medical professional postgraduate degree. How to strengthen the appropriate scientific research training while successfully completing the 33-months clinical rotation. With the social development and increasing demands, the original training model that training professional technical personnel and scientific academic personnel seperately has been confirmed unable to adapt to the current requirements. Combining with the practi-cal experience of the medical postgraduate degree education, we put forward some constructive suggestions of boosting the innovation of the medical postgraduate degree education from several aspects, such as optimizing the training process, strengthening the stage man-agement, improving the quality of the tutor team, smoothing the communication mechanism between teachers and students, cultivating clinical research thinking, etc.
ABSTRACT
With the development of economy and society, the change of heath concept and increased demands for health care , the cultivation of postgraduates majoring in clinical medicine is facing a lot of problems which seriously affects the quality of culti-vation.The article analyzed the problems and reasons in the clinical medicine postgraduate cultivation.We stated the competency of clinical medicine postgraduates according to the transition of health demands, global medical development and practical requirements for clinical personnel in China.We elaborated the required post competence for clinical medicine postgraduates on the basis of its con-tent and characteristics.We proposed to strengthen the cultivation of clinical medicine postgraduates by the reform and support of the government, enhanced construction of teachers, improved course plan and cultivation process, perfected assessment system in order to make the students competent to their posts.
ABSTRACT
In order to improve the effectiveness of continuing medical education in military comprehensive hospital , we trans-formed the idea of continuing medical education , regulated the system , strengthened the hardware , paid more attention to the manage-ment, provided different ways for continous medical education .With the practice of continuing medical education , we should design a scientific management system and diversified activities to impove continous medical education .The article elaborated the practice of new transitional pattern of continuing medical education in our hospital in order to provide some references for the optimization of con -tinous medical education in comprehensive military hospitals .
ABSTRACT
Photoacoustic tomography is a developing, promising,non-invasive imaging method in the medical clinic diagnosis. It is an ultrasound-mediated biophotonic imaging method based on the intrinsic optical absorption properties of tissue and ultrasonic detection, and combines the merits of both high contrast advantage of pure optical imaging and high resolution advantage of pure ultrasound imaging. Photoacoustic tomography can be performed by detecting photoacoustic waves instead of detecting photons. In photoacoustic tomography, imaging contrast is based primarily on the optical properties of biological tissues, and imaging resolution is based primarily on the ultrasonic waves. It can avoid the influence of optical scattering on imaging resolution in principle, and can provide tomography of tissues with high contrast and high spatial resolution at medium depths. Photoacoustic tomography can provide an effective approach to studying the structures, physiological properties, metabolisms, pathological properties of biological tissues. It has important potential clinical applications in the early non-invasive detection of cancers, structural and functional in vivo imaging. A brief introduction of photoacoustic imaging mechanisms is gives, and the imaging methods, the image reconstruction algorithm and the potential biomedical applications of photoacoustic tomography are reveiewed.
ABSTRACT
AIM: To evaluate the effect and safety of Rhodamine 123 (Rh123)-mediated photodynamic treatment (PDT) on acute graft versus host disease. METHODS: An acute graft versus host disease (aGVHD) mice model was established using C57B/6 mice as donors and BALB/c mice as recipients. Mixed lymphocytic cells were cultured with Rh123 (50 nmol/L) and irradiated by argon laser 30 mW/cm2 for 3 min, then transplanted to BALB/c recipient mice mixed with donor bone marrow. Hepatopoietic recovery, aGVHD occurrence, survival time after transplantation and pathological changes were observed. In addition, CD3+CD69+ positive rates of MLC were examined by flowcytometry. RESULTS: Occurrence of aGVHD decreased, degree of pathological manifestation became milder, survival rates were higher than non PDT groups. CD3+CD69+ rates of MLC cells treated with photodynamic therapy (PDT) and cultured for 24 h significantly decreased. CONCLUSION: Rh123-mediated PDT can effectively prevent aGVHD of allogeneic bone marrow transplantation in mice.
