不同本底ROI勾画法对肾小球滤过率测定的影响

目的探讨不同本底RO I勾画法对肾小球滤过率(GFR)测定的影响。方法对41例患者行肾动态显像,按不同本底RO I勾画法计算GFR,与标准Gates法比较,观察结果偏离程度及导致结果偏离因素。结果logistic多因素分析表明,本底RO I位置、大小、本底RO I与肾脏RO I间的距离均是影响GFR的因素(左肾χ2=307.2,56.5,44.7,右肾χ2=288.6,48.1,21.2,P=0.000);本底位于肾脏RO I正下方较大范围内,其GFR与标准Gates法GFR十分接近。结论Gates法勾画本底RO I时,将本底RO I设置于肾脏正下方,以减少本底大小、本底与肾脏间距离对GFR的影响。

临床前列腺癌研究取材的基本方法

验室与临床传统的临床病理取材仅限于诊断的目的，随着临床的需要和科研技术的发展，对病理取材有了新的严格的要求。我们就实验室１９８６～１９９５年在美国德州大学Ｍ．Ｄ．Ａｎｄｅｒｓｏｎ癌症中心以及１９９５年至今在Ｖｉｒ－ｇｉｎｉａ大学泌尿学系从事前列腺研究的经验，提出下列几点，谨供国内同道参考。１血和血清标本的处理在患者常规化验时取静脉血１．０ｍｌ，单独放入另一消毒的试管中，３７℃水浴箱中３０ｍｉｎ后移入４℃冰箱中过夜。次日离心沉淀（５００ｇ，室温下５ｍｉｎ），取澄清液放入－２０℃冰箱内待测或低温干燥…     

临床检验应重视细胞形态教学与实习

当前高科技飞速发展，促进了临床医学领域的飞速发展．为临床医学检验教学提供了新内容和新观点。同时也出现了一种不良倾向，在一些从事检验教学的老师及某些医院检验人员中．出现重仪器、轻技术的倾向，对检验基本理论及技能掌握程度不够。同样做血常规化验。用显微镜手工操作只收0．8元钱．而用血液自动分析仪(T540)6项指标收6元钱，     

61例流行性出血热患者临床各期血液流变学观察

通过血液流变学的检测,观察61例流行性出血热患者临床各期的改变。发现出血热患者临床各期,全血粘度的均数都高于正常对照的上限值。五期中少尿期升高不明显,发热期和多尿期明显升高。红细胞聚集指数各期均有显著性升高,提示出血热整个病程是DIC的形成过程。通过动态观察临床各期血液流变学的检测可及时正确地指导临床工作。     

正常新生儿,婴儿血液动力流变学检测

血液动力流变学是机体的重要生理机能,其变化是观察人体生理、病理机能一项重要指标。正常儿童血液动力流变学测值国内报告甚少,婴儿及新生儿测值尚未见报道,我们对100例新生儿、48例1岁内婴儿进行了血液动力流变学24项参数检测。

不同液体术前急性高容量血液稀释对深静脉血栓病人血液流变学的影响

Objective To investigate the effects of acute hypervolemic hemodilution (AHH) with different fluids on blood rheology in patients with deep vein (femoral and iliac) thrombosis. Methods Thirty ASA I or II patients aged 40-64 yr who had developed deep vein thrombosis in 48 h and were scheduled for embolectomy were randomly divided into 3 groups ( n = 10 each) ; group I normal saline (NS) ; group II 6 % HES 200/0.5 ( HES) ; group IE gelofusine (GEL). AHH was performed with normal saline, 6% HES or gelofusine infusion at 20 ml·kg-1 ·h-1 for 40 min. MAP, HR and SpO2 were monitored. Blood loss, volume of blood transfusion and fluid infused and urine output during operation were recorded. Anesthesia was induced with fentanyl 3-5 fig/kg, etomidate 0.15-0.30 mg/kg, propofol 1-2 mg/kg and succinylcholine 1-2 mg/kg and maintained with 2% isoflurane and propofol infusion at 5-8 mg·kg-1·h-1 and intermittent iv boluses of vecuronium. The patients were mechanically ventilated (VT 8 ml/kg, RR 12 bpm). PaO2 and PaCO2 were maintained within normal range. Venous blood samples were obtained before and after AHH for measurement of hematocrit (Hct), whole blood viscocity (WBV) at low or high shear rates, plasma viscosity, RBC aggregation and RBC deformation. RBC aggregation index and RBC deformation index were calculated. Results MAP and HR were stable in all patients. The amount of blood transfusion and fluid infused was significantly less in group HES and GEL than in group NS. The WBV at low or high shear rates in group HES and GEL, Hct in all 3 groups and RBC aggregation index in group HES were significantly decreased after AHH, but the RBC deformation index was significantly increased in group HES. Conclusion Colloid is better than crystalloid and HES is better than gelofusine in improving intraoperative hypercoagulability and sluggish blood flow.
