【单选题】患者，男性，58岁，因疲劳、乏力6个月来诊，发现脾肋下2cm，化验Hb158g/L，WBC13.8×109／L，PLT2150×109/L，骨髓增生活跃，全片见巨核细胞380个，血小板聚集成堆。本例最可能的诊断是（）
A.
原发性血小板增多症
B.
骨髓增生异常综合征
C.
慢性髓细胞白血病
D.
继发性血小板增多症
E.
慢性原发性骨髓纤维化
【单选题】有如下事件过程：Private Sub Form_Load() Show Dim Arr() As Variant Arr = Array(1, 3, 5, 7, 9, 11, 13, 15) Call converse(Arr) For i = 0 To 7 Print arr(i); Next iEnd Sub 以上程序的功能是，通过调用Converse过程，将数组Arr中的元素逆序存放并输出...
A.
Private Sub converse(dim a() as Variant ) Dim T For i = LBound(A) To UBound(A) T = a(i) a(i) = a(UBound(A) - i) a(UBound(A) - i) = T Next i End Sub
B.
Private Sub converse(dim a() as Variant) Dim T Dim J As Integer J = (LBound(A) + UBound(A)) / 2 For i = LBound(A) To J T = a(i) a(i) = a(UBound(A) - i) a(UBound(A) - i) = T Next i End Sub
C.
Private Sub converse(a() As Variant) Dim T For i = LBound(A) To UBound(A) T = a(i) a(i) = a(UBound(A) - i) a(UBound(A) - i) = T Next i End Sub
D.
Private Sub converse(a() As Variant) Dim T Dim J As Integer J = Int((LBound(A) + UBound(A)) / 2) For i = LBound(A) To J T = a(i) a(i) = a(UBound(A) - i) a(UBound(A) - i) = T Next i End Sub
【单选题】下列是血小板聚集特点的是
A.
血小板聚集是血小板之间的黏附
B.
血小板聚集与血小板活化同时发生
C.
血小板聚集除了GPⅡa/Ⅲb参与无其他因子参加
D.
GP Ⅰb/Ⅴ/Ⅸ有缺陷时，其聚集减弱
E.
凝血酶、PGI2、ADP等都能促进血小板聚集
