Abstract

The present invention belongs to the technical field of medicines and specifically relates to an application of ulinastatin in preparations of anti-nasopharyngeal carcinoma metastasis medicines. Through cell in-vitro tests, the ulinastatin is found to be capable of inhibiting metastasis of nasopharyngeal carcinoma cells, does not inhibit growth of the nasopharyngeal carcinoma cells, and is less toxic and more conducive to rehabilitation of patients with nasopharyngeal carcinoma.

Description

technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to the application of ulinastatin in the preparation of nasopharyngeal carcinoma metastasis-resistant medicine. Background technique [0002] Ulinastatin (UTI) was isolated and purified from the fresh urine of healthy adult males. It is a glycoprotein composed of 143 amino acids and is a broad-spectrum protease inhibitor. Experimental studies have found that it has the function of inhibiting the activities of various enzymes such as plasmin, hyaluronidase, granulocyte elastase, α-chymotrypsin, and trypsin. Ulinastatin is mainly synthesized by the liver, metabolized by the kidneys, and then excreted in the urine. Its decomposed small molecular components also have a strong activity of inhibiting hydrolase. In addition to inhibiting trypsin, ulinastatin can also inhibit a variety of pancreatic enzyme activities, so it has a good therapeutic effect on acute pancreatitis ...
