颈部实性包块超声引导下徒手穿刺活检的临床价值

颈部解剖结构甚为复杂,病灶周边血管及神经组织丰富,且颈部形态不平整,尤其是锁骨上区域,超声引导下颈部包块徒手穿刺活检术较其他部位相对难度大、风险高。本组对我院经超声引导下徒手穿刺活检的颈部实性包块的操作要领进行总结,以期提高超声引导下颈部包块的穿刺成功率。

Quantitative analysis of magnetic anomaly of reinforcements in bored in-situ concrete piles

We quantitatively study magnetic anomalies of reinforcement rods in bored insitu concrete piles for the first time and summarized their magnetic anomaly character. Key factors such as measuring borehole orientation, borehole-reinforcement distance, and multiple-section reinforcement rods are discussed which contributes valid and quantitative reference for using the magnetic method to detect reinforcement rods. Through tests with model piles, we confirm the accuracy of theoretical computations and then utilize the law discovered in theoretical computations to explain the characteristics of the actual testing curves. The results show that the Za curves of the reinforcement rod reflect important factors regarding the reinforcement rods, such as rod length, change of reinforcement ratio, length of overlap, and etc. This research perfects the magnetic method for detecting reinforcement rods in bored in-situ concrete piles and the method has great importance for preventing building contractor fraud.

多发性肛管直肠恶性黑色素瘤一例

患者男,59岁,因“血便10余天”入院。查体:腹平软,无压痛及反跳痛,未触及腹部包块。肛门指诊膝胸位6点钟方向可触及肛门齿状线上2处隆起性病变,可推动。白光内镜下可见肛门口2处并联隆起的病灶,超声内镜示:2处病灶截面大小分别约为14 mm×12 mm和12 mm×12 mm(图1),病理活检诊断为恶性黑色素瘤。
