目的探讨缺血性脑卒中患者血尿酸(SUA)水平与脑动脉狭窄之间的关系。方法从收治的缺血性脑卒中患者中,随机选择经脑血管造影术确诊有脑动脉狭窄的患者186例、无狭窄患者42例。根据造影结果,将脑动脉狭窄分为轻度狭窄组74例,中度狭窄组66例和重度狭窄组46例。单支血管狭窄103例,多支血管狭窄83例。比较不同组别间SUA水平的差异以及SUA与脑动脉狭窄程度之间的关系。结果无狭窄患者SUA水平明显低于有狭窄患者(P0.05),轻度狭窄组SUA水平明显低于中度狭窄组(P0.05),中度狭窄组SUA水平低于重度狭窄组(P0.05)。脑动脉狭窄与血尿酸水平呈正相关(r=0.413,P0.05),Logistic回归分析显示SUA并不是脑动脉狭窄的独立危险因素(P=0.213)。结论 SUA水平与脑动脉狭窄呈正相关,但不是脑动脉狭窄的独立危险因素。

Objective To study the relationship between serum uric acid(SUA)level and cerebral artery stenosis in patients with ischemic stroke.Methods Patients with ischemic stroke were examined with subtraction and diagnosed as with(186)and without cerebral artery stenosis(42).Patients with stenosis were further grouped as slight(74),moderate(66),and severe stenosis(46).There were 103 pa-tients with single stenosis and 83 patients with dual cerebral artery stenosis.The serum uric acid levels of the groups patients were researched. Results The level of SUA was significantly lower in patients without than in patients with cerebal artery stenosis(P<0.01);SUA was sig-nificantly lower in patient with mild stenosis than in patients with moderate stenosis(P<0.05);significantly lower in patients with moderate stenosis than in patients with severe stenosis(P<0.05).Spearman rank correlation analysis showed that SUA level and the degree of cerebral artery stenosis was positively correlated(r=0.413,P<0.01).

Objective To discuss the diagnostic value of 16-slice spiral CT angiography in assessment of lower extremity arterial occlusive disease. Methods Twenty patients with symptomatic lower extremity peripheral arterial occlusive disease underwent 16-slice spiral CT angiography. CT angiograms were produced using maximum intensity projection(MIP), volume rendering(VR) technique, multiplanar reformation(MPR), and curve planar reformation(CPR). The arterial system was divided into 8 segments. Each segment was classified as normal, mild stenosis, moderate stenosis, severe stenosis and occlusion. Results In 20 patients, a total number of 72 stenosis and occlusion segments were observed . Among the 72 segments,the common iliac artery was found in 5 segments, the external iliac artery was in 8 segments, the femoral artery was in 10 segments, the anterior tibial artery was in 11 segments, the posteior tibial artery was in 12 segments, the peroneal artery was in 4 segments. Conclusion 16-slice spiral

目的：观察胸椎管狭窄症患者椎管狭窄程度与脊髓内高信号发生情况及临床症状之间的关系。方法根据胸椎管狭窄程度，将 MRI 检查确诊的99例胸椎管狭窄症患者分为3组：轻度狭窄组（椎管残余率≥66．7％）34例，中度狭窄组（33．3％≤椎管残余率﹤66．7％）37例，重度狭窄组（椎管残余率﹤33．3％）28例，比较各组患者脊髓内高信号的发生率及神经功能受损情况。结果在 MRI T2加权像上，轻度狭窄组有9例（26％）出现脊髓高信号改变，中度狭窄组有18例（49％），重度狭窄组有19例（68％），3组间比较差异具有统计学意义（P ＜0．05）；根据日本骨科协会（JOA）评分系统，轻度狭窄组 JOA 评分为（7．7±2．8）分，中度狭窄组为（6．3±2．0）分，重度狭窄组为（5．8±2．2）分，轻度狭窄组与中度狭窄组、轻度狭窄组与重度狭窄组间比较差异均有统计学意义（P 均＜0．05），而中度狭窄组与重度狭窄组比较差异无统计学意义（P ＞0．05）。脊髓内具有高信号的患者 JOA 评分为（4．9±1．5）分，无高信号者 JOA 评分为（7．2±2．1）分，二者比较差异有统计学意义（P ＜0．05）。结论因胸椎退行性疾病导致胸椎管狭窄的患者，胸椎管狭窄越重，病程越长，越容易出现髓内高信号；同

Objective It is to observe the correlation of thoracic spinal stenosis with occurrence of intramedullary increased signal intensity (IISI) and clinical symptoms.Methods 99 patients who had thoracic spinal stenosis were clearly diagnosed and divided into 3 groups according to the degree of spinal stenosis: 34 cases in mild stenosis group (the residual rate of spinal canal ≥66.7%), 37 cases in moderate stenosis group (the residual rate of spinal canal ≥33.3% and <66.7%), 28 cases in severe stenosis group (the residual rate of spinal canal <33.3%).The occurrence rate of IISI and nerve function damage condition were recorded and analyzed respectively.Results 9 patients (26%) who with IISI were in mild stenosis group, 18 cases (49%) were in moderate stenosis group and 19 cases (68%) were in severe stenosis group, there was significant differ-ence among 3 groups (P <0.05).The Japanese Orthopedic Association (JOA) scale was 7.7 ±2.8 in group A, 6.3 ±2.0 in group B and 5.8 ±2.2

Biliary strictures are the most common complications after liver transplantation and can be classied as anastomotic strictures (AS) and nonanastomotic strictures (NAS), according to the different location of the strictures. The two types of biliary strictures differ in pathology, risk factors, therapy, and prognosis. Combined with the literature at home and abroad, the risk factors and therapy of the two types of biliary strictures after liver transplantation are reviewed in this paper.
