| 2 | Staging of portal hypertension and portosystemic shunts using dynamic nuclear medicine investigations显示文摘AIM: To explore portal hypertension and portosys-temic shunts and to stage chronic liver disease (CLD) based on the pathophysiology of portal hemodynam-ics. METHODS: Per-rectal portal scintigraphy (PRPS) was performed on 312 patients with CLD and liver angio-scintigraphy (LAS) on 231 of them. The control group included 25 healthy subjects. We developed a new model of PRPS interpretation by introducing two new parameters,the liver transit time (LTT) and the circu-lation time between right heart and liver (RHLT). LTT for each lobe was used to evaluate the early portal hypertension. RHLT is useful in cirrhosis to detect liver areas missing portal in? ow. We calculated the classical per-rectal portal shunt index (PRSI) at PRPS and the hepatic perfusion index (HPI) at LAS. RESULTS: The normal LTT value was 24 ± 1 s. Abnor-mal LTT had PPV = 100% for CLD. Twenty-seven non-cirrhotic patients had LTT increased up to 35 s (median 27 s). RHLT (42 ± 1 s) was not related to liver disease. Cirrhosis could be excluded in all patients with PRSI < 5% (P < 0.01). PRSI > 30% had PPV = 100% for cirrhosis. Based on PRPS and LAS we propose the clas-sifi cation of CLD in 5 hemodynamic stages. Stage 0 is normal (LTT = 24 s,PRSI < 5%). In stage 1,LTT is increased,while PRSI remains normal. In stage 2,LTT is decreased between 16 s and 23 s,whereas PRSI is increased between 5% and 10%. In stage 3,PRSI is increased to 10%-30%,and LTT becomes undetect-able by PRPS due to the portosystemic shunts. Stage 4 includes the patients with PRSI > 30%. RHLT and HPI were used to subtype stage 4. In our study stage 0 had NPV = 100% for CLD,stage 1 had PPV = 100% for non-cirrhotic CLD,stages 2 and 3 represented the transition from chronic hepatitis to cirrhosis,stage 4 had PPV = 100% for cirrhosis. CONCLUSION: LTT allows the detection of early por-tal hypertension and of opening of transhepatic shunts. PRSI is useful in CLD with extrahepatic portosystemic shunts. Our hemodynamic model stages the evolution of portal hypertension and portosystemic shunts. It may be of use in the selection of patients for interferon therapy. | Mircea Dragoteanu Ioan A Balea Liliana A Dina Cecilia D Piglesan Ioana Grigorescu Stefan Tamas Sabin O Cotul | 2008 | World Journal of Gastroenterology2008，14，24： | 7 |
| 3 | 灌浆与钢箍加固震损砖墙的抗震性能试验研究显示文摘为准确评价汶川地震中地震损伤砖石古塔砌体墙在加固修复后的抗震性能,试验研究了灌浆与钢箍复合加固震损砌体墙筒试验模型的相关抗震性能参数。以四川某震损古砖塔为样本,研制了四种单层砌体墙筒初始试件,模拟地震作用使其破坏,采用灌浆与钢箍进行加固修复,制作所需试件,通过低周反复荷载试验,得到了试件的相关数据。试验结果表明:与未损伤的原结构相比,灌浆与钢围箍复合加固可提高震损砖砌体结构的延性与耗能能力,但对提高震损结构刚度的贡献不大,修复结构的开裂荷载亦有所降低。 | 李胜才 Dina D'Ayala 呼梦洁 | 2014 | 土木建筑与环境工程2014，36，4： | 3 |
