1、1.A few weeks after minor surgery,a 14-year-old boys routine laboratory testing reveals 0.4 mg/dl of direct bilirubin(直接胆红素)and 1.6 mg/dl of indirect bilirubin(间接胆红素).The sole physical finding is scleralicterus and noother abnormalities can be detected.What is the(10.0)A.Crigler-Najjar syndrome Type

2、 I 先天性葡萄糖醛酸转移酶缺乏症 B.Crigler-Najjar syndrome Type II C.Gilberts syndrome 吉伯特氏症候群 D.Rotors syndrome E.DubinJohnson syndrome 吉伯特（Gibert）氏病是一种先天性、非溶血性黄疸，它是由于肝细胞窦侧微绒毛对胆红素的摄取障碍所致 总胆红素：间接胆红素偏高，直接胆红素偏高，说明肝细胞性黄疸，肝细胞受到损害，肝功能减退，肝脏不能完全将间接胆红素转化为直接胆红素，同时肝内胆管受压引起了排泄障碍，直接胆红也不能完全排到胆道，同时有可能伴有急性黄疸型肝炎，慢性活动性肝炎，肝硬化，肝癌等疾病

3、。直接胆红素：说明是由阻塞性黄疸造成的。间接胆红素：说明可能是溶血性黄疸造成的，直接胆红素升高也可能会有输血时血型不合，贫血等原因 在肝功能化验里，胆红素正常值范围如下：总胆红素1.71 17.1mol/L（0.1mg/dl 1.0mg/dl）直接胆红素03.42 mol/L（00.2mg/dl）间接胆红素 013.68mol/L（00.8mg/dl）2.Which of the following classes of lipoproteins(脂蛋白)results from the interaction of VLDL and lipoprotein lipase?(10.0)A.VL

4、DL 极低密度脂蛋白 B.LDL 低密度脂蛋白 C.IDL D.HDL 高密度脂蛋白 E.Chylomicronremnant 3.Elevation of what substance is the likely cause of yellow skin in a hypothyroid adolescent?(10.0)什么物质的增多导致青少年黄皮肤 由于患者缺乏甲状腺激素，胡萝卜素不能转变为维生素 A，所以有胡萝卜素血症，皮肤显现黄白色 A.Carnitine 卡尼丁（肉毒碱）B.Carotene 胡萝卜素 C.Direct bilirubin 直接胆红素 D.Indirectbilir

5、ubin 间接胆红素 E.Total bilirubin 总胆红素 4.Deficiency of lysosomal a-1-4-and 1-6 glucosidase(acid maltase)is characteristic of which one of the following diseases?(10.0)A.Forbes disease 糖原沉积型 1,6 B.Pompes disease 型 1,4 C.Anderson disease 1,4-1,6 D.Taruis disease 肌磷酸果糖激酶 5.In what childhood disease does amm
