数据说明

Conditions: Cystic Fibrosis. The pancreas plays a key role in the regulation of whole-body glucose metabolism in humans. It contains 1 to 3 million islets, each of which contains several types of endocrine cells including insulin-secreting beta cells, glucagon-secreting alpha cells, and somatostatin- secreting delta cells. Insulin is released in response to a rise in blood glucose after a meal, and promotes glucose utilization by peripheral tissues (e.g., skeletal muscle), which allows the return of blood glucose to a fasting level. Glucagon is released when blood glucose falls below a normal fasting level (~80-100 mg/dL) and it acts on the liver in opposition to insulin, enhancing hepatic glucose production. Somatostatin’s role in whole body glucose homeostasis is somewhat more complex. The role it plays in acutely regulating whole-body glucose homeostasis is small in healthy humans. On the other hand, it is capable of inhibiting the secretion of both insulin and glucagon, regardless of ambient metabolic conditions. In addition to its ability to regulate hormone secretion, somatostatin is also known to reduce glucose absorption from the gastrointestinal tract. CF is the most common life-limiting genetic disease in Caucasians. It is caused by recessive mutations in the gene encoding CF transmembrane conductance regulator (CFTR). The primary pathologic change is secretion of thick ductular mucus, which leads to progressive obstructive damage to the lungs and exocrine pancreas. Damage to the exocrine pancreas, which is responsible for the secretion of digestive enzymes, leads to exocrine pancreas insufficiency (PI) manifested as diarrhea and malabsorption of ingested nutrients, requiring pancreatic enzyme replacement. Pathological changes of exocrine PI occur as early as the first few months of life, and most CF patients are diagnosed with PI before they reach adulthood. The degree of exocrine PI correlates with risk of developing cystic fibrosis related diabetes (CFRD). However, not all CF patie
