He had no symptoms and the physical examination was normal. Tumor markers were within the normal range. Abdominopelvic enhanced computed tomography showed a mass in the lower abdominal cavity and the tumor had a complete capsule. Diagnostic laparoscopy was then performed, which showed that a spheroid mass with a complete capsule was located at the antimesenteric border of the distal ileum 20 cm from the ileocecal valve, measuring 6.0 cm × 6.0 cm × 5.0 cm. Considering that the malignancy of the tumor cannot be ruled out, and there is a risk of rupture during laparoscopic surgery, the patient was conver-ted to an open surgery. Partial resection of the ileum with the tumor was performed, followed by a side-to-side anastomosis. The tumor was gray-red in color,filled with grayish yellow mucus and had no septum. The postoperative pathology revealed that the cystic wall was lined by pseudostratified ciliated columnar epithelium without cellular atypia. The wall consisted of bronchial mucous glands and smooth muscle fbers, and no abnormalities were found in adjacent ileumtissues. Thus, a diagnosis of bronchogenic cyst of the ileum was made.展开更多

文摘乙醛是酒类饮品中的风味物质,但乙醛过高不仅会影响酒类饮品的风味,还会对人体产生潜在的危害。从可食用的益生菌中筛选可以代谢乙醛的菌株,并探究活性菌株的乙醛代谢能力跟乙醇诱导的关系。通过静息细胞法筛选获得的鼠李糖乳杆菌HCCB 20591具有较强代谢乙醛的能力,且其代谢能力受乙醇诱导。当乙醇诱导浓度为3%,诱导时间为12 h时,乙醛转化率达到41.13%。GC-MS分析其代谢产物除了乙酸外,还生成了乙醇。采用Real time RT-PCR方法分析相关基因的转录水平,发现乙醛代谢是乙醇脱氢酶、乙醛脱氢酶和醛氧化还原酶综合催化作用的结果。
