慢性肾功能衰竭患者受损的胃动力及其与胃肠症状的关系

背景：慢性肾功衰竭（CRF）患普遍存在胃肠道（GI）症状，但这些症状的发病机制还不清楚。CRF患的胃动力功能目前还存在争议，GI症状与胃动力的关系也尚未阐明。该研究目的是阐明CRF患的胃动力与GI症状的关系。方法：通过体表胃电图（EGG）和胃的固体餐排空及”C-乳酸呼气试验评估21例终末期肾衰患与21例健康对照的胃动力并进行比较。将所有患的GI症状严重度量化。结果：两组的EGG显示，CRF患正常餐后胃动力的发生率及胃的蠕动能力较健康对照组显降低，表现为胃排空延迟。3例胃动力正常的患没有胃肠不适症状，10例EGG异常并胃排空延迟的患比正常患GI症状评分显增高。结论：CRF患的胃动力降低，包括受损的胃肌电活动和延迟的胃排空。胃动力降低可能是CRF患发生GI症状的重要因素。

Impaired gastric motility and its relationship to gastrointestinal symptoms in patients with chronic renal failure

Unlike root abscess, fistula formation is quite uncommon in aortic valve endocarditis. In this report, we describe a patient with subacute bicuspid aortic valve endocarditis complicated by aortic insufficiency, mycotic aneurysms of the aortic root and fistulous communication between the aorta and the left atrium and his recovery upon surgical treatment.
