Methods:Twenty-three patients with CAOD awaiting bypass operation were observed as research group.Thirty-one patients undergoing elective open repair of an infrarenal abdominal aortic aneurysm were observed as control group. Clamping and declamping arterial for anastomoses were served as ischemia reperfusion injury. LDH, CK, MB as indicators of skeletal injury before operation and first 3 days after operation were detected.

以接受旁路手术治疗的23例慢性下肢动脉闭塞患者为试验组，以接受腹主动脉原位置换的31例腹主动脉瘤患者为对照组，以术中阻断及开放血管为急性IRI因素，以乳酸脱氢酶、肌酸激酶、肌红蛋白为检测指标，研究两组骨骼肌对急性IRI的反应。

Results: The renal perfusion was increased in diabetes group after the injection of alloxan. The PSI, AUC and ascending slope rate of the curve of the time-intensity curve were increased in 1w and 2w with decreased of HPT; the pathological examination exhibited glomeruli hypertrophy and no thickening of basal lamina. The PSI and AUC in 4w and 6w were more than that of control group; the PIT and ascending slope rate of the curve got closed to normal in 4w and 6w; the intercapillary cells increased. The speed of ascending slope rate of the curve in 8w, 10w and 12w was slower, shown as PIT and HPT delayed; the pathological examination showned increasing of mesangial cell, hyperplasia of mesangial matrix and thickening of basal lamina, followed with obliteration of partial micrangium, glomerular sclerosis and reduce of PSI in 12w.

结果：糖尿病组兔注射四氧嘧啶后肾皮质血流灌注增大，1周、2周表现为时间-强度曲线参数中峰值强度升高、曲线下面积增大、达峰时间缩短、曲线上升斜率升高，此时病理可见肾小球肥大，系膜基质正常，基底膜无增厚；4周、6周，峰值强度、曲线下面积高于对照组，达峰时间、曲线上升斜率接近正常，系膜细胞增多。8周、10周、12周，达峰时间延长、曲线上升斜率减慢、峰值强度减半时间延长，病理出现肾小球系膜细胞明显增多，系膜基质增生，基底膜增厚，至12周病理出现部分毛细血管管腔闭塞，肾小球节段性硬化，峰值强度测值减低。

在三维立体 CT 上胸段椎板间空间闭塞的例数以及胸段棘上韧带和棘间韧带骨化的例数同样被评估。

BACKGROUND: Implantation of artificial joint of bone cement can result in long-term blocking of recipient site medullary canal and blood vessel lesion, and lead to changes in intraosseous pressure and bone blood flow of distal femoral shaft.

背景：骨水泥固定型人工关节假体骨腔内的植入必然涉及受区骨髓腔的长期闭塞和髓内血管的破坏，由此而产生的髓内压和血流的变化是材料本身的影响所致，很有研究价值。
