摘要:目的: 研究尿微量白蛋白与冠心病的相关性。 方法 : 按冠状动脉造影诊断标准将116例患者分为冠心病组(82人) 与非冠心病组(34人),测定晨尿白蛋白/ 肌酐浓度值(ACR),比较两组患者尿ACR 并分析ACR与冠脉病变程度的相关性。 结果 : 冠心病组ACR显著高于非冠心病组的; ACR与冠脉计分呈显著的直线正相关。 结论 :冠心病患者ACR水平升高,微量白蛋白尿与冠状动脉病变范围和程度密切相关, 且对冠状动脉狭窄程度具有独立预测价值。Abstract: Objective: To investigate the relationship between microalbuminuria and coronary artery disease(CAD). Methods : According to the diagnostic standard of coronary artery angiography,116 patients were divided into CAD group (82 patients) and nonCAD group (34 patients). The albumin and creatinine concentrationratio ratio(ACR) in morning urine samples from patients of both groups was estimated and compared. The correlation of ACR to the extent of coronary lesions was analyzed. Results : ACR in the CAD group was significantly higher than that in nonCAD group. A distinctly linear positive correlation existed between ACR and the score of the coronary lesions. Conclusion : ACR increase in patients with CHD.Micoalbuminuria was associated with the severity of coronary lesions in patients with CHD and is an independent predictor of CAD.
Repairs of the wornds arter cicatricial resection in 15 cases of claw hands after burn by retrograde transfer of posterior interosscous vascularized fascial flap, of forearm were reported. The function of the hand was improved. The deformities were corrected by arthroplasty or arthodesis. The applied anatomy and operatirc techniques were introduced. The intraoperative problems were discussed.
OBJECTIVE To investigate a new operative method for repairing nonunion and defect of tibia. METHODS First, observe the relation between the joint branches of descending genicular artery and the saphenous branch of descending genicular artery in 10 cadevers. Then the medial femoral condylar bone flap pedicled with the saphenous vessels was prepared in 4 cadavers for simulated purpose. Clinically, two patients with tibial nonunion were treated by transplantation of this pedicled bone flap. RESULTS: In the 4 simulated operations, the ink which was injected into the femoral artery could be released from the joint branches. And in the clinical operation, the area of the pedicled bone flaps were 5.0 cm x 2.0 cm x 1.5 cm and 4.5 cm x 1.5 cm x 1.5 cm respectively. Followed up for 8 to 12 weeks, the fracture unioned well. CONCLUSION: This operation is simple and reliable, it is characterised by 1. unnecessary to anastomosis the vessels 2. reliable blood supply 3. high quality of bone flap 4. either bone flap or bone-skin flap can be chosen 5. long vessel pedicle.
Objective To observe the clinical effect of intravenous thrombolytic therapy for central retinal artery occlusion (CRAO) with poor effect after the treatment of arterial thrombolytic therapy. Methods Twenty-four CRAO patients (24 eyes) with poor effect after the treatment of arterial thrombolytic therapy were enrolled in this study. There were 11 males and 13 females. The age was ranged from 35 to 80 years, with the mean age of (56.7±15.6) years. There were 11 right eyes and 13 left eyes. The visual acuity was tested by standard visual acuity chart. The arm-retinal circulation time (A-Rct) and the filling time of retinal artery and its branches (FT) were detected by fluorescein fundus angiography (FFA). The visual acuity was ranged from light sensation to 0.5, with the average of 0.04±0.012. The A-Rct was ranged from 18.0 s to 35.0 s, with the mean of (29.7±5.8) s. The FT was ranged from 4.0 s to 16.0 s, with the mean of (12.9±2.3) s. All patients were treated with urokinase intravenous thrombolytic therapy. The dosage of urokinase was 3000 U/kg, 2 times/d, adding 250 ml of 0.9% sodium chloride intravenous drip, 2 times between 8 - 10 h, and continuous treatment of FFA after 5 days. Comparative analysis was performed on the visual acuity of the patients before and after treatment, and the changes of A-Rct and FT. Results After intravenous thrombolytic therapy, the A-Rct was ranged from 16.0 s to 34.0 s, with the mean of (22.4±5.5) s. Among 24 eyes, the A-Rct was 27.0 - 34.0 s in 4 eyes (16.67%), 18.0 - 26.0 s in 11 eyes (45.83%); 16.0 - 17.0 s in 9 eyes (37.50%). The FT was ranged from 2.4 s to 16.0 s, with the mean of (7.4±2.6) s. Compared with before intravenous thrombolytic therapy, the A-Rct was shortened by 7.3 s and the FT was shortened by 5.5 s with the significant differences (χ2=24.6, 24.9; P＜0.01). After intravenous thrombolytic therapy, the visual acuity was ranged from light sensation to 0.6, with the average of 0.08±0.011. There were 1 eye with vision of light perception (4.17%), 8 eyes with hand movement/20 cm (33.33%), 11 eyes with 0.02 - 0.05 (45.83%), 2 eyes with 0.1 - 0.2 (8.33%), 1 eye with 0.5 (4.17%) and 1 eye with 0.6 (4.17%). The visual acuity was improved in 19 eyes (79.17%). The difference of visual acuity before and after intravenous thrombolytic therapy was significant (χ2=7.99, P＜0.05). There was no local and systemic adverse effects during and after treatment. Conclusion Intravenous thrombolytic therapy for CRAO with poor effect after the treatment of arterial thrombolytic therapy can further improve the circulation of retinal artery and visual acuity.
In order to summarize the experience in the treatment of ischemic necrosis of lower extremities resulted from thrombotic occluded angittis, 15 cases were reported, which were treated by primary arterization in situ of V. Saphena magna. With a period of follow-up, 4-26 months on the average, it was found that symptoms in 14 cases were much allayed obviously, except 1 case with little relief. It suggested that primary arterization in situ of V. saphena magna could improve the circulation of the ischemic extremity rapidly without any influence of venous reflux.
One hundred and twenty-eight cases of peripheral aneurysm were reported.Traumatic prsucdoaneursyms(87cases)dominated and aneurysm in lower extremities(68 cases)consisted of most the cases.Rupture of aneurysm and massive kaemomhage is the most serious complications(22 cases in the report).Therefore,operative treatment should be performed soon after the diagnosis is ascertained.Resteration of normal blood flow should be the aim.Intracystic repairation is indicated in pseudoaneurysm with part of the vascular wall invaded.Artificial graft may be indicated for aneurysm of the middle and large artery,and autovenous graft for the smaler arteries.Aneurysm may be resected if the procedure is easy to perform or there is severe inflammation around the aneurysm.Proper postoperative drainage is important.General heparinization during blockade of local circulation is also important in case of vascular grafting. We concluded that proper selection of operative procedure is essential for better prognosis.
