Pancreatic pseudocysts are fluid collections around the pancreas. They arise due to sudden or long-standing inflammation of the pancreas. While some will disappear when the inflammation of the pancreas settles down, others remain and cause symptoms such as abdominal pain, indigestion, vomiting, and weight loss.
Duodenal internal covering membrane made of degradable biocompatible material and application thereof
ActiveCN102626330ANo allergic reactionNo toxic reactionSurgeryNon-surgical orthopedic devicesBile JuiceMedical equipment
The invention provides a duodenal internal covering membrane, which is made of degradable shape memory biocompatible material and relates to degradable medical equipment internally installed in a digestive tract. After the internal covering membrane is implanted into a duodenum, chyme can be split from bile and pancreatic juice, so stomach exudates are prevented from being directly digested, absorbed and metabolized in the duodenum, and the histocompatibility is good; after being implanted into a human body, the duodenal internal covering membrane is steady, is not easy to slide off to be incarcerated and can be gradually degraded in the human body after 2 months to 5 years, so complicated operation and the injury to organs and tissue, which are caused when the duodenal internal covering membrane is removed from the human body in the future, are avoided, a rebound effect achieved after the original barrier is instantaneously and thoroughly dismounted can be slowed down, and the duodenal internal covering membrane can be prepared into medical equipment which is used for curing obesity and diabetes mellitus and does not need to be removed from the human body in the future; and tube-shaped part sinking induced by gastrointestinal motility and jejunum content backflow caused by the decrease of a gap between a tube-shaped part of the internal covering membrane and the inner wall of the duodenum can be avoided. The prepared medical equipment for curing the obesity and the diabetes mellitus can achieve the effects of dropping prevention, removal exemption, rebound inhibition and injury reduction.

Application of lectin group recognized carbohydrate chain in distinguishing mucinous cystic neoplasm from serous cystic neoplasm
The invention discloses application of lectin group recognized carbohydrate chains in distinguishing mucinous cystic neoplasm from serous cystic neoplasm. The lectin group recognized carbohydrate chains disclosed by the invention are glycosylated protein carbohydrate chains recognized by lectin groups consisting of WGA (trticum vulgaris agglutinin), BPL (bauhinia purpurea lectin), STL (solanum tuberosum (potato) lectin), DBA (dolchos biflorus agglutinin), PTL-I (psophocarpus tetragonolobus lectin I) and MAL-I (maackia amurensis lectin I). The carbohydrate chains are different in capsula pancreatic fluid of patients suffering from mucinous cystic neoplasm and serous cystic neoplasm, the contents of the carbohydrate chains recognized by STL, WGA, BPL and DBA in the capsula pancreatic fluid of patients suffering from MCN (mucinous cystic neoplasm) are remarkably higher than those in the capsula pancreatic fluid of patients suffering from SCN (serous cystic neoplasm), the contents of the carbohydrate chains recognized by PTL-I and MAL-I in the capsula pancreatic fluid of the patients suffering from MCN are remarkably lower than those in the capsula pancreatic fluid of the patients suffering from SCN, the sensitivity of the combination of WGA and BPL in distinguishing the patients suffering from SCN from the patients suffering from MCN is 0.714, and the specificity is 1. The results show that the lectin group can be used for distinguishing the patients from SCN from the patients suffering from MCN.
