脑部疾患如脑血管病、脑外伤、脑缺氧、脑炎和各种脑病时,尤其是严重的脑出血患者,常呕吐出咖啡色样物或解出柏油样大便,这说明合并有胃肠道出血。这种情况叫脑-内脏联合病变,这就是说胃肠相继于脑部发生了病变,这反映出人体的统一性及大脑皮层和内脏之间的相互关系。脑-内胜联合病变多见于脑部疾患的急性期,一般预示着病情严重。为什么脑部疾患时会产生胃肠道出血呢?这可能主要是由于丘脑下部及其有关的联系纤维(来自额叶的、去脑干脊髓的纤维)受损所致,而丘脑下部与胃酸、胃粘膜血流量和胃肠蠕动等有密切的关系。由于丘脑下部受到损害,在应激情况下促肾上腺皮质激素 Brain disorders such as cerebrovascular disease, traumatic brain injury, cerebral hypoxia, encephalitis and a variety of encephalopathy, especially in patients with severe cerebral hemorrhage, often vomit brown samples or asphaltene-like stool, indicating that with gastrointestinal Road bleeding. This situation is called brain-visceral joint disease, which means that successive gastrointestinal lesions in the brain, which reflects the unity of the human body and the relationship between the cerebral cortex and internal organs. Brain - victorious lesions more common in acute brain disorders, generally indicates a serious condition. Why gastrointestinal bleeding occurs when a brain disorder occurs? This may be mainly due to impaired hypothalamus and its associated connective fibers (fibers from the frontal lobe that demyelinate the spinal cord), whereas the lower part of the thalamus is associated with gastric acid, Gastric mucosal blood flow and gastrointestinal motility are closely related. As the lower part of the thalamus is compromised, adrenocorticotropic hormone is under stress conditions
