When seen from the practice and development of modern medicine,we are facing challenges from various ethical problems which arise from the progress of life support technique,industry and network technique and its application in medicine,life sciences and electronic sciences.Nowadays,the legislation of medical ethics and regulations have become a heated issue drawing the attention of doctors,pharmacists,laboratorians,nurses,medical information staff,religions personnel,philosophers,medical scientists,and lawyers.This thesis tries to analyses the main ethical problems in the use of medical information so as to justify potential eligible ethical norms in clinical practice,expecting to draw the attention of relevant staff and general public and the fulfillment of ethical norms in the medical practice.

Objective To investigate the application of xingnaojing injections ( XNJI) in inpatients and further provide a reference for the rational drug use. Methods The retrospective investigation was carried out by reviewing 186 hospitalization records with XNJI from a certain hospital from January 2014 to June 2015. The usage, dosage, and indication of XNJI were analyzed. Results Unlabeled use of XNJI was found in the neurology department inpatients. 59. 7% inpatients were treated with overdosed XNJI, and 13. 4% were treated with a single drug dose of 40 mL. The inappropriate solvent selection accounted for 49. 5%. Compatibility of XNJI and western medicine injection accounted for 54. 8%. It was also found that XNJI was used together with potassium chloride in clinic (47. 8%). Conclusion There exist some irrational uses of XNJI in clinic, thus the use and management of traditional Chinese medicine injections should be standarized.

To investigate the contents and distribution of matrix metallproteinases(MMP) in abdominal aortic aneurysm(AAA) on protein level, forty male Wistar rats were randomly divided into two groups, the rats of experimental group were perfused with pancreatic elastase in the isolated abdominal aorta to construct the model of AAA. Laparotomy was preformed on the 14th day after operation, the aortas were measured and harvested. The rats of control group were operated with the aortas harvested immediately. Immunohistochemical staining and computer image analysis were performed to analyze the contents and distribution of MMP 2 and MMP 9. The aortic diameter progressed to aneurysmal dimension in the experimental group. Immunohistochemistry study revealed that the MMP contents in AAA exceeded that in normal aorta obviously. The MMP 2 cotents in AAA tunica media were higher than MMP 9. It is suggested that MMP 2 plays the main role in extracellular matrix degradation of AAA tunica media.

To investigate the prevention and management of postoperative complications of lower extremity amputation for arterial occlusive diseases, a retrospective analysis was made in 18 lower extremity amputations which were performed on 14 patients from Jan 1996 to Dec 1999. The mean age of the patients was 72. Before opeoation,78 6% of the patients were complicated with coronary artery disease, 69.9% with high blood pressure and 78.6% with diabetes mellitus, 43.4% with vascular reconstruction history. 6 above the knee amputations, 7 below the knee amputations, 1 hemiterpene amputation and 4 amputations of the toes were performed. Postoperative myocardial infarction occarred in 2 cases, gangrene of the stump in 3 cases and infection in 1 case, the total incidence rate of complication was 33%. The results showed that lower extremity amputation is not a complex operation, but preoperative estimation of the level of amputation and postoperative intensive care can reduce the postoperative rate of complication.

Colonic ischemia is a well documented complication of abdominal aortic reconstruction. In this retrospective study of abdominal aortic aneurysm patients undergone endovascular graft exclusion, the incidence and management of this complication were investigated. From Mar 1997 to Apr 2000,among the 40 patients who received elective endovascular graft exclusion for,infrarenal abdominal aortic aneurysm the bilateral hypogastric artery was retained in 30 patients, the unilateral hyogastric artery was retained in 10 patients. One patient had lower abdominal pain on the 28th day after operation, CTA showed the bilateral hypogastric artery occlusion, the symptoms were relieved after drug treatment. Retaining unilateral hypogastric artery can prevent the colonic ischemia after endovascular graft exclusion for abdominal aortic aneurysm, the chronic colonic ischemia secondary to bilateral hypogastric artery occlusion can be relieved by effective drug treatment.

To investigate the diagnosis and treatment of Stanford B thoracic aortic dissection eomplicated with renal ischemia, 29 cases of Stanford B thoracic aortic dissection admitted from January 1996 to April 2000 were retrospectively studied. Three of them had renal ischemia secondary to aortic dissection (2 acute,1 chronic). One patient in acute stage died 3 days after onset, the other patient in acute stage complicated with bilateral lower extremity ischemia was treated with fenestration of intimal flap, and the symptom was relieved. The patient in chronic stage was treated with endovascular graft exclusion for aortic dissection and the renal ischemia was relieved because of the restored true lumen blood. The results showed that palliative bypass helps relieve symptoms and improve survival rate. For the chronic aortic dissection complicated with renal ischemia, endovascular graft exclusion can restore the true lumen blood and relieve renal ischemia.

This paper reviewed the development of vascular surgery in diagnosis and treatment in recent years,the concepts and specialty of Duplex scan,MRA, CTA were discussed,the progress and problems of traditional revascularization and endovascualr technique were analyzed.
