Objective To establish a simple and rapid method for the determination of 1,3-dideoxygalactonojirimycin in Bombycis Faeces, a potent glucosidase inihibitor, by HPLC. Methods A RP-HPLC method with fluorescence detection has been developed. Results The HPLC method developed in this research has a good reliability including accuracy and precision. The detection limit was less than 72 ng. Conclusion This method is sufficiently sensitive for determining 1,3-dideoxygalactonojirimycin in Bombycis Faeces and other related products.

OBJECTIVE: To explore the better management of the stoma in endoscopic dacryocystorhinostomy. METHOD: To review the 102 chronic dacryocystitis patients (109 eyes), who underwent the endoscopic dacryocystorhinostomy surgery with silver clips used to maintain the stoma. They were given combined therapy after the surgery, and were followed up for a period range from 3-73 months. RESULT: 99/109 eyes (91%) were cured, 5/109 eyes (4.5%) were improved, and the total effective rate reached to 104/109 (95.5%). CONCLUSION The application of silver clip in endoscopy dacryocystorhinostomy surgery and combined therapy after the surgery can effectively prevent the stoma stenosis or atresia.
