以压电换能器作为超声波源,在日本三浦湾海岸一处洞室内,对12m距离范围内的原位压缩波速度与衰减进行了为期1年的连续观测。我们首次检测到波速与衰减的周期性变化,其变化幅度分别为0.3%和4%,这和全日与半日的月潮与日潮是一致的。这种周期性变化也和海潮负荷引起的原位区域应变变化相吻合;而应变变化本身可由观测场地100m以外的应变记录估算得到。每当区域应变相对最大(扩张)时,波速都会达到相对最小,而衰减变为相对最大。这意味着原位岩石中孔隙或裂纹的开合导致了这些周期性变化。波速变化显示出了明显的14天的周期性,与大潮和小潮的周期相一致,这是由于波速改变对潮汐应变改变的非线性响应而引起的,表现为波速改变依赖于潮汐膨胀离开其峰值的快慢。

作者： kensuke yamamura Toru Beppu Tatsunori Miyata Shinichi Akahoshi Takatoshi Ishiko Department of Surgery Yamaga City Medical CenterYamagaJapan Department of Gastroenterological Surgery Graduate School of Life SciencesKumamoto UniversityKumamotoJapan

An associating liver partition and portal vein ligation for staged hepatectomy(ALPPS)has been developed as a novel surgical technique for patients with insufficient future liver remnant volume even after portal vein embolization(PVE)±hepatic arterial or venous embolization or conventional two-stage hepatectomy(TSH)(1-5).ALPPS was thought to be a breakthrough but high-risk procedure;however,it recently became a safer technique after the developing phase(1-3).Conversion surgery is strongly recommended for patients with initially unresectable liver tumors that are deemed resectable by systemic chemotherapy or hepatic arterial chemotherapy/embolization(6,7).The primarily targeted diseases are colorectal liver metastases(CRLM)and hepatocellular carcinoma(HCC).ALPPS is indicated for patients undergoing not only primary surgery but also conversion surgery.

Aslanger’s sign,also known as the arterial pulse tapping artifact or electromechanical association artifact,is an electrocardiographic artifact caused by arterial pulsation at the site where the limb leads of the standard 12-lead electrocardiogram near the radial or posterior tibial arteries are positioned,particularly in hyperdynamic states.[1–8]It occurs in every cardiac cycle with a constant coupling interval between the QRS complex and *** synchronization with the underlying heart rhythm makes it less likely to be recognized as an artifact compared to unsynchronized artifacts,such as those caused by limb movement and inadequate contact between the electrode and skin.[1,2,7,8]Almost all reported cases of Aslanger’s sign exhibit an unusual waveform morphology in all 12 leads except one of the standard 12-lead *** sign is often confused with an electrocardiographic finding commonly observed during acute coronary events.
