| 1 | Arterial stimulation with simultaneous venous sampling for localizing insulinomas显示文摘Purpose: The present study aimed to assess the accuracies of arterial stimulation with simultaneous venous sampling(ASVS) in preoperative localization of insulinomas. Materials and Methods: A cohort consisting of 6 males and 14 females(median age, 48.5y; range, 28–62y) with pathologically proven insulinomas were included in this study. Selective angiographies were performed with the superior mesenteric artery(SMA), gastroduodenal artery(GDA), proximal splenic artery, and midsplenic artery in all individuals. Then ASVS procedures were followed after angiographies for these arteries. Clinical characteristics of the patient and the tumor number, location, and size were recorded. The accuracy of preoperative localization of insulinomas was tested. Results: A total of 22 tumors were identified by histopathological diagnosis. The mean size of the tumor was 1.40±0.60 cm. Five tumors were in the head/neck region and 17 in the body/tail region. ASVS accurately localized 17/20(85%) cases with only biochemical data and 19/20(95%) cases with biochemical data and angiography images. Variant pancreatic arterial anatomy was revealed in 2 false cases with inferior pancreatic artery replaced by the superior mesenteric artery. Conclusion: ASVS was highly accurate in localizing insulinomas and should be performed in most of the patients with suspected insulinomas before the operation. | Zhiyuan Wu Tingwei Su Daming Wu Xiaoyi Ding Zhongmin Wang Wei Huang Ziyin Wang Qin Liu Hua Zhang | 2018 | Journal of Interventional Medicine2018，1，1： | 1 |
| 2 | Bilateral inferior petrosal sinus sampling for the treatment of Cushing's disease Data from 52 cases from one institute over an eight-year period显示文摘The present study analyzed data from 108 Cushing's disease patients,who underwent trans-sphenoidal surgery in one hospital between January 2003 and April 2010,to investigate the performance value of bilateral inferior petrosal sinus sampling (BIPSS).Of the 108 patients,52 underwent BIPSS prior to surgery and 56 did not.Results showed that BIPSS accuracy for the diagnosis of Cushing's disease was 86.5% (45/52),and accuracy for adenoma lateralization during surgery was 76.9% (40/52).In addition,early remission rate was significantly greater compared to patients without BIPSS.Results demonstrated that BIPSS facilitated localization and diagnosis of Cushing's disease and helped to predict adenoma lateralization. | Changyan Fan Xiuhua Shi Qingfang Sun Liuguan Bian Weiguo Zhao Jiankang Shen Hua Zhang Tingwei Su Weiqing Wang Xiaoying Li Guang Ning Liang Kong Lingling Hu | 2011 | Neural Regeneration Research2011，6，28： | 1 |
| 3 | Effect of Shale Reservoir Characteristics on Shale Oil Movability in the Lower Third Member of the Shahejie Formation, Zhanhua Sag显示文摘To reveal the effect of shale reservoir characteristics on the movability of shale oil and its action mechanism in the lower third member of the Shahejie Formation(Es3l), samples with different features were selected and analyzed using N2 adsorption, high-pressure mercury injection capillary pressure(MICP), nuclear magnetic resonance(NMR), high-speed centrifugation, and displacement image techniques. The results show that shale pore structure characteristics control shale oil movability directly. Movable oil saturation has a positive relationship with pore volume for radius > 2 μm, as larger pores often have higher movable oil saturation, indicating that movable oil is present in relatively larger pores. The main reasons for this are as follows. The relatively smaller pores often have oil-wetting properties because of organic matter, which has an unfavorable effect on the flow of oil, while the relatively larger pores are often wetted by water, which is helpful to shale oil movability. The rich surface provided by the relatively smaller pores is beneficial to the adsorption of immovable oil. Meanwhile, the relatively larger pores create significant pore volume for movable oil. Moreover, the larger pores often have good pore connectivity. Pores and fractures are interconnected to form a complex fracture network, which provides a good permeability channel for shale oil flow. The smaller pores are mostly distributed separately;thus, they are not conducive to the flow of shale oil. The mineral composition and fabric macroscopically affect the movability of shale oil. Calcite plays an active role in shale oil movability by increasing the brittleness of shale and is more likely to form micro-cracks under the same stress background. Clay does not utilize shale oil flow because of its large specific surface area and its block effect. The bedding structure increases the large-scale storage space and improves the connectivity of pores at different scales, which is conducive to the movability of shale oil. | NING Chuanxiang MA Zhongliang JIANG Zhenxue SU Siyuan LI Tingwei ZHENG Lunju WANG Guozhen LI Fengxun | 2020 | Acta Geologica Sinica(English Edition)2020，94，2： | 0 |
