ABSTRACT
Objective To study the value of emergency angiography and interventional therapy in digestive tract hemorrhage. Methods 123 cases was performed with repeated angiography after perfusing vasodilator substance in those patients without bleeding signs in the first angiography. According to with or without bleeding during angiography, these cases were divided into group A (the patients is bleeding during angiography) and group B (the patients' stool bleeding examined were negative before angiography) for analysis. The patients with bleeding demonstrated angiographically had accepted the arterial embolization and/or infusion of vasoconstrictor substance later on. Results 90.8% patients of group A was found bleeding and 47.22% patients of group B was found bleeding on angiography. Bleeding was stopped immediately in all those patients with arterial embolization and 82.7% of those patients with vasoconstrictor substance infusion. Conclusions The detective rate of bleeding in active stage is greater than that of in resting stage on emergency angiography of patients with digestive tract hemorrhage ( P
ABSTRACT
AIM: To establish the method of fingerprint analysis of Crocus sativus L. and compare their HPLC-FPS of eight kinds of Crocus sativus L. from different sources. METHODS: HPLC with ZORBAX SB-C 18 column was used, the mobile phase was a linear gradient of methanol containing 1% acetic acid and water containing 1% acetic acid in 40min, the detection wavelength at 312nm. RESULTS: 12 marker peaks were separated. The methodological evaluation showed that the method had a good repeatability, and the marker peak area ratio of different samples were different. CONCLUSION: This method is simple and accurate with good reproducibility and can be used for a quality control for Crocus sativus L.
