To explore the impact of middle and low dose atorvastatin on peripheral endothelial progenitor cells (EPCs) in patients with acute myocardial ischemia injury via investigating EPC proliferation, migration, differentiation and secretion of cytokines. Method: A total of 80 patients with acute ST-segment elevation myocardial infarction (STEMI) were randomly divided into 2 groups: Observation group, the patients received atorvastatin 40 mg and Control group, the patients received atorvastatin 20 mg. n=40 in each group. The number of circulating EPC, EPC proliferation ability and the secretion of cytokines before and at different time points after drug therapy were examined by means of MTT, flow cytometry and ELISA. Results: The number of EPC was obviously increased with greatly changed migration ability within 2 weeks atorvastatin treatment in both groups. The secretion of cytokines presented that the contents of VEGF, bFGF, CXCR were elevating first followed by reducing thereafter, while the content of SIRT1was continuously increasing during the period of treating. The above parameters were similar between 2 groups. Conclusion: Middle and low dose atorvastatin could effectively improve EPC proliferation and migration, increase the expressions of CXCR4, VEGF, bFGF and SIRT1 in STEMI patients.

Objective To summarize our experience in percutaneous transluminal angioplasty(PTA) in the management of thoracoabdominal aortic stenosis of Takayasu's arteritis. Methods From 1987~2001, 12 patients of Takayasu's arteritis with thoracoabdominal aortic stenosis underwent PTA. Aortography and pressure of stenotic segment of arota before and after angioplasty were used to evaluate efficacy. Color Doppler ultrasound examination and Doppler segmental pressure measurement were used in follow-up. Results Success was achieved in all cases without mortality and serious complications except for 1 case of acute thrombosis of iliofemoral artery. The residual stenosis were less than 50% in all cases and the pressure gradient was 5 0mmHg~10 5 mmHg with average pressure being 7 2 mmHg after angioplasty ,although they were 25mmHg~46 mmHg averaging of 37 7 mmHg before angioplasty. All cases were followed up for 9(12~72) months and the result was good without lumen restenosis and obstruction. Conclusions PTA is the first choice for Takayasu's arteritis of thoracoabdominal aortic stenosis of local size and proved to be safe, effectiveand economical. It is also effective for long size cases. It is not necessary to dilate aorta stenosis to normal size, and reducing pressure gradient effectively is enough.

Objective To evaluate the effects of anatomic and extra-anatomic reconstruction in cases of aortoiliac occlusion on perioperative morbidity and mortality. Methods Clinical data of 382 cases were retrospectively analyzed with reference to perioperative morbidity and mortality by Logistic regression. Results One hundred and twenty- six patients were enrolled into analysis. Impact factors included lower extremities necrosis(OR 0. 13 95% CI 0. 33 - 0. 36,P=0.005), simultaneous distal reconstruction (OR 11.29 95% CI 1.25 - 102.53,P =0.012). Perioperative complications developed in 13. 5% cases. Goldman cardiac risk(OR 26. 83 95% CI 4. 85 - 49. 54,P =0. 001),age (OR 37. 13 95% CI 3. 29 -48. 53,P = 0. 003),renal dysfunction(OR 5. 71 95% CI 1. 25 -25. 02, P = 0. 024) and surgical modality (OR 0. 03 95% CI 0. 002 - 0. 34, P =0. 005) were identified as risk factors. Perioperative mortality was 8. 7%. Goldman cardiac risk (OR 23. 86 95% CI 3. 90 - 45. 99,P =0. 032),age(OR 65. 56 95% CI 4.88-87.64, P =0.002) and surgical modality(OR 0.02 95% CI 0. 001 -0.262, P=0.005) were among factors predicting perioperative death. Conclusions Age over 70 years, renal dysfunction, intermediate or higher Goldman cardiac risk, moderate or severe emphysema are risk factors of perioperative mortality and morbitity of aortoiliac reconstruction. Extra-anatomic reconstruction should be considered against the risk factors in poor risk patients.

ObjectiveTo evaluate the efficacy of axillo-axillary bypass grafting for the treatment of contralateral arterial ischemia of upper limb. Method 53 cases underwent axillo-axillary artery PTFE graft bypass among those there were 46 cases of subclavian artery occlusion and 3 cases of subclavian artery aneurysm and 4 cases of trauma. Preoperatively 33 cases suffered from a symptom of extremity ischemia and 18 cases with subclavian artery blood steal. Result Good results were achieved in all cases without any complications. Doppler test showed the gradient of bilateral brachial pressure artery was less 10 mmHg in all cases. ConclusionAxillo-axillary artery PTFE graft bypass is an effective method for subclavian artery reconstruction with less trauma and complications. It is especially suitable for the elders with concomitant heart brain and lung diseases. It is also applicable for cases in which the subclavian arteries are not easily accessible due to artery aneurysm and artery trauma.
