AIM To investigate changes in hepatic and splenic stiffness in patients without chronic liver disease during liver resection for hepatic *** Patients scheduled for liver resection for hepatic tumors were considered for enrollment. Tissue stiffness measurements on liver and spleen were conducted before and two days after liver resection using point shear-wave elastography. Histological analysis of the resected liver specimen was conducted in all patients and patients with marked liver fibrosis were excluded from further study analysis. Patients were divided into groups depending on size of resection and whether they had received preoperative chemotherapy or not. The relation between tissue stiffness and postoperative biochemistry was investigated. RESULTS Results are presented as median(interquartile range). 35 patients were included. The liver stiffness increased in patients undergoing a major resection from 1.41(1.24-1.63) m/s to 2.20(1.72-2.44) m/s(P = 0.001). No change in liver stiffness in patients undergoing a minor resection was found [1.31(1.15-1.52) m/s vs 1.37(1.12-1.77) m/s, P = 0.438]. A major resection resulted in a 16%(7%-33%) increase in spleen stiffness, more(P = 0.047) than after a minor resection [2(-1-13) %]. Patients who underwent preoperative chemotherapy(n = 20) did not differ from others in preoperative right liver lobe [1.31(1.16-1.50) vs 1.38(1.12-1.56) m/s, P = 0.569] or spleen [2.79(2.33-3.11) vs 2.71(2.37-2.86) m/s, P = 0.515] stiffness. Remnant liver stiffness on the second postoperative day did not show strong correlations with maximum postoperative increase in bilirubin(R^2 = 0.154, Pearson's r = 0.392, P = 0.032) and international normalized ratio(R^2 = 0.285, Pearson's r = 0.534, P = 0.003). CONCLUSION Liver and spleen stiffness increase after a major liver resection for hepatic tumors in patients without chronic liver disease.

抗磁悬浮技术利用物质的抗磁特性,无需外界能量输入即可实现常温被动静态稳定悬浮,获得众多学者的关注。尤其是近30年来,随着微细制造与强磁场技术的发展,抗磁悬浮相关研究持续增加。目前,国外众多研究机构基于抗磁悬浮原理已经开展了较为丰富的相关研究工作,但国内在该领域的研究成果相对较少,研究内容较为单一。针对国内该领域这一研究现状,从抗磁悬浮机理、抗磁悬浮特点及抗磁悬浮相关应用研究成果进行全面的综述。提出抗磁悬浮不仅具备无磨损、无需润滑、低能耗等优点外,还具有常温被动静态稳定悬浮、微纳米尺度应用、低刚度等特点;指出该技术在微纳旋转机械、振动能量捕获、高灵敏度传感器、生物细胞/微粒子操纵等领域具有非常广阔的应用前景。为国内学者开展相关抗磁悬浮研究提供了综述资料。
