Isolated resection of bemangioma in the cau-date lobe is challenging due to the surgical anatomy of caudate lobe. The caudate lobe consists three portions: Spiegel's lobe, paracaval portion and caudate process. Most of the blood supply of caudate lobe is provided by the posterior segmental branches of the portal vein and left hepatic artery. The hepatic venous drainage encompasses a few sizable and several small branches that join the inferior vena cava. Selection of the ideal route for bepatectomy, adequate mobilization of the liver, preparatory placement of band for hepatic vascular occlusion are key factors during the operation.

Objective To explore the feasibility of detecting atherosclerosis with 7.0T MR and Micro-PET. Methods Ten 46-week-old ApoE-/- mice with high lipid diet for 6 months were selected to establish atherosclerosis models. Among them, 5 mice underwent MRI before and 12 h, 24 h, 36 h after injection of SPIO, respectively, and the other 5 mice were injected with ~(18)F-fluorodeoxyglucose (~(18)F-FDG) through tail vein and observed with Micro-PET after 1 h, 2 h and 3 h. The specimens of abdominal aorta were taken for pathologic examination. Results Atherosclerotic plaques were observed in all animals with 7.0T MRI after 6 months high lipid diet. Thirty-six hours after the injection of SPIO, the high signal rings were thinner and the lumen of blood vessels were wider than those before injection on T2WI. Radioactive concentration was observed in abdominal aorta and both sides of iliac artery 3 h after the injection of ~(18)F-fluorodeoxyglucose (~(18)F-FDG). Pathological examination showed the formation of atherosclerotic plaques and the aggregation of the macrophages. Conclusion 7.0T MRI and Micro-PET can be used to observe the macrophage-rich plaque and to judge the vulnerability of plaque, thus provide theoretical basis for early detection, diagnosis and treatment of atherosclerosis.

In this paper, We designed and accomplished a low frequency pulsed strong magnetic fields generator, which provides a pulsed magnetic field with the intensity range from 0.1-2.5 T and the adjusted time interval of pulse. This device is easy to operate and performs reliably. It can work steady for a long time and has been successful used in the experiments of biological effects of electromagnetics.

This article reports the diagnosis and treatment of a case of acromegaly in a pregnant patient who took bromocriptine during pregnancy and delivered successfully. A retrospective summary of the clinical data and treatment outcomes before and after two pregnancies of the patient is provided. The patient took bromocriptine during the second pregnancy, and her condition remained stable. A baby girl was delivered by caesarean section at full term. The article suggests that pregnancy in acromegaly patients, after the stabilization of the condition, can lead to favorable outcomes. The use of dopamine receptor agonists during pregnancy does not increase adverse events during the perinatal period.
