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.     

氟乙酰胺中毒患儿心肌酶活性变化及其临床意义

为探讨氟乙酰胺中毒患儿的心肌酶活性变化 ,我们对 37例氟乙酰胺中毒患儿进行了血清心肌酶活性测定 ,现总结报告如下。1　对象及方法1.1　对象 :37例患儿均为 1996年 3月～ 1999年12月在我科住院的氟乙酰胺中毒患儿 ,其中男性2 3例 ,女性 14例 ;年龄 1～ 3岁 13例 ,～ 7岁 15例 ,～ 12岁 9例。所有患儿均有明确误服氟乙酰胺灭鼠药的病史 ,自发病至入院时间 1～ 8ｈ。对照组为门诊健康查体儿童 ,共 31例 ,男性 2 0例 ,女性 11例 ;年龄 1～ 3岁 11例 ,～ 7岁 13例 ,～ 12岁 7例。1.2　方法 :氟乙酰胺中毒患儿于入院当日及此后6日每日晨抽空腹…     

慢性肾功能衰竭升降失衡证红细胞膜Na~+、K~+-ATP酶的研究

对30例慢性肾衰升降失衡证患者按升降不及、升降反常分两组,用保元汤加大黄治疗,总有效率63.3%。同时测定红细胞膜 Na~ 、K~ -ATP 酶活性(μM/mg 蛋白·小时)和哇巴因抑制率(%)与30名健康人比较,两组酶活性分别降低71%、76%;抑制率分别降低31%、33%。其中16例治疗后酶活性均值分别由治疗前85.1、75.3,提高到219.9、185.9;抑制率均值分别由治疗前62.7、57.2,提高到77.2、70.2。临床症状好转,肌酐、尿素氮下降。表明细胞膜运转障碍与升降失衡证存在联系,中药对酶活性有调节作用。     

急性胰腺炎的诊治进展

急性胰腺炎（acute pancreatifis，AP）是指多种病因引起的胰酶激活，继以胰腺局部炎症反应为主要特征，伴或不伴有其他器官功能改变的疾病。临床上，大多数患者的病程呈自限性；20％～30％患者临床经过凶险。总体死亡率为5％～10％。AP临床上表现为急性、持续性腹痛（偶无腹痛），血清淀粉酶活性增高大于或等于正常值上限3倍，影像学提示胰腺有（无）形态改变，排除其他疾病者。可有（无）其他器官功能障碍。少数病例血清淀粉酶活性正常或轻度增高。     

冷饭热后难消化

剩饭重热后再吃,或将剩饭炒了再吃,不少人以为这样既卫生又节约。其实,剩饭重热后再吃难以消化,久而久之可能引起胃病。 让我们先来看看米饭中所含的主要成分淀粉是怎样在体内消化吸收的吧。首先,口腔内的唾液淀粉酶将淀粉水解成糊精及麦芽糖。其次,是在小肠内由胰腺分泌的胰淀粉酶和双糖酶继     

初次献血对红细胞膜Na+-K+-ATP酶活性的影响

目的探讨初次献血对红细胞膜Na+-K+-ATP酶活性的影响.方法应用比色法分别检测50例符合献血条件的健康初次献血者献血前后的红细胞膜Na+-K+-ATP酶活性,并对结果进行分析.结果初次献血者献血前后红细胞膜Na+-K+-ATP酶活性分别为3.121±0.441和2.907±0.397 μmol.Pi/107 RBC.h,两者比较无明显差异(P＞0.05).结论初次献血对红细胞膜Na+-K+-ATP酶活性无影响,献血不会造成红细胞功能损伤.
