题目：
腹部损伤行腹腔穿刺，抽得不凝血液，应诊断为（）。
A.实质性脏器破裂
B.腹膜后血肿
C.误穿入腹腔血管
D.空腔脏器裂伤
E.以上均可
答案：
参考答案：A
解析：诊断性腹腔穿刺，本法简便安全，阳性率可达90%，腹腔穿刺，以下腹部最常见。抽出液体如是血液且迅速凝固，则表明针头误入血管。若不凝固，提示实质性脏器破裂出血。若抽到0.1ml不凝固血液，则为穿刺阳性。
腹部损伤行腹腔穿刺，抽得不凝血液，应诊断为（）。 A.实质性脏器破裂 B.腹膜后血肿

Young girls at high risk for depression appear to have a malfunctioning reward system in their brains, a new study suggests. The finding comes from research that (1) a high-risk group of 13 girls, aged 10 to 14, who were not depressed but had mothers who (2) recurrent depression and a low-risk group of 13 girls with no (3) or family history of depression. Both groups were given MRI brain (4) while completing a task that could (5) either reward or punishment.
(6) with girls in the low-risk group, those in the high-risk group had (7) neural responses during both anticipation and receipt of the reward. (8) , the high-risk girls showed no (9) in an area of the brain called the dorsal anterior cingulated cortex (背侧前扣带皮质), believed to play a role in (10) past experiences to assist learning.
The high-risk girls did have greater activation of this brain area (11) receiving punishment, compared with the other girls. The researchers said that this suggests that high-risk girls have easier time (12) information about loss and punishment than information about reward and pleasure.
"Considered together with reduced activation in the striatal (纹状体的) areas commonly observed (13) reward, it seems that the reward-processing system is critically (14) in daughters who are at elevated risk for depression, (15) they have not yet experienced a depressive (16) ," wrote Ian H. Gotlib, of Stanford University, and his colleagues. " (17) , longitudinal studies are needed to determine whether the anomalous activations (18) in this study during the processing of (19) and losses are associated with the (20) onset of depression," they concluded. The study was published in the April of the Archives of General Psychiatry.
