we have observed the effect of antibiotic drug and the 654-2 on the gastroentenc tract, in the early stage of intestinal ischemia, using the model of intestinal ischemia in rats. Compared with the control group, the lesion degree of intestinal mucosa, liver, kindey and lung lessened obviously, the frequency of intestinal bacteria translocation decreased (P

Objective To observe the expression of Vascular endothelial growth factor 165 (VEGF165) in transplantation of MSCs to repair an ischemically damaged bind limb in a rabbit model.Methods MSCs were cultivated in vitro and transfected with non-replicative adenoviral vector with VEGF165 gene. Four weeks after treatment, Real-time PCR assessed the expression of VEGF165 in the damaged limb.Results It was confirmed that VEGF165 was successfully transfected into MSCs.Real-time PCR assessments revealed the expression of Vascular endothelial growth factor 165 (VEGF165) in 4 weeks after treatment. Conclusion VEGF165 can be transfected into MSCs and express in rabbit model of ischemic limb.

Thoracic and cardiovascular surgery teaching is the focal and difficult point in the whole surgery teaching.This article introduces the authors'reform by using advanced multimedia and image equipment to enhance teaching effect in both theory and practice,using the modern modes such as logic guide,case study and inter-communication to inspire students'passion and by emphasizing basic skill and asepsis environment to build normative teaching in thoracic and cardiovascular surgery.

Eight-year medical education is an important way to train high-level medical students.According to the eight-year medical educational characteristics of neurosurgery,with reference to the teaching achievement both in domestic and foreign medical schools in conjunction with the characteristics of military medical university students,eight-year medical student clinic practice of neurosurgery has been improved through the application of clinical teaching,and achieved good teaching effect.

Preoperative anesthetic interview is not only an important part of clinical teaching,but also a vital tache of improvement for medical treatment quality.Unlike internal medicine and surgery,interview for anesthesiology department has its own characteristics.Anesthesiology department of Changzheng hospital has put great emphasis on preoperative anesthetic interview.Some experiences about preoperative anesthetic interview were introduced in our article.

The theory of Constructivism was applied in different aspects of clinical teaching of surgery.The lessons were designed according to the character of students.Problem solving was emphasized during the course of teaching.An interactive and cooperative atmosphere was constructed.And a variety of additional related materials were provided.All these measures made the teaching activity more accord with the objective rule of clinical knowledge learning.Hence a better teaching effect was achieved.

To improve the teaching quality of advanced students on minimally invasive surgery is important for the generalization of new techniques on this subject.The teaching plan should be made according to the academic level of these students.Both theory learning and clinical practice should be emphasized.Multimedia tools should be adopted and English teaching should not be neglected.All these means help to better the teaching quality of advanced students on minimally invasive surgery.

Orthopaedic surgery is a fast developing subject in clinical surgery.Based on the characteristics of the orthopaedic surgery and aiming to enhance the medical students’practical ability of basic skills and clinical thinking we adopt the explorative clinical teaching which can be helpful to training students’initiative of finding and working out a solution by themselves and cultivating their capability of innovation and creation.

The mode of using standardized patients has been applied in cardiothoracic surgery teaching to assess students efficiency.It alleviates the conflict of the shortage of resource for clinical teaching and improves the quality of teaching and achieves good results.

The students are consciously taught how to think the surgery and how to analyze and solve problems in the animal surgery curriculum.
