ABSTRACT
Objective:To establish an HPLC fingerprint of Yiqing granules to provide reference for the effective quality control. Methods:The analysis was carried out on an analytical Agilent ZORBAX SB-C18(250 mm×4.6 mm,5 μm)column with gradient elution by acetonitrile(A)-0.2% phosphoric acid solution(adjusting pH to 3.0 with triethylamine,B)(0-5 min:10% A→20%;5-20 min:20% A→30% A;20-25 min:30% A→45% A;25-35 min:45% A;35-45 min:45% A→80% A;45-50 min:80% A)at the detection wavelength of 254 nm and the flow rate of 1.0 ml·min-1,and the column temperature was 35 ℃. Twelve batches of Yiqing granules were determined by HPLC and a common mode of fingerprint was established. Results:There were 22 common peaks in the fingerprints of the twelve batches of Yiqing granules,and seven of them were identified. The similarities of fingerprints of the twelve batches of Yiqing granules were over 0.990 suggesting good reproducibility. Conclusion:The developed method is accurate and feasible,and can be used for the quality control of Yiqing granules.
ABSTRACT
OBJECTIVE:To observe the Hp eradication situation and safety of three kinds of drug regimen in the treatment of active chronic gastritis with helicobacter pykori(Hp)infection. METHODS:150 active chronic gastritis patients with Hp infection were randomly divided into group A(50 cases),group B(50 cases)and group C(50 cases). Group A received Omeprazole enter-ic-coated capsule 20 mg,orally,twice a day+Amoxycillin capsules 1.0 g,orally,3 times a day+Clarithromycin tablet 0.5 g,oral-ly,once a day. Group B additionally received Colloidal bismuth pectin capsule 150 mg,orally,3 times a day. Group C received Omeprazole enteric-coated capsule 20 mg,orally,twice a day+Amoxycillin capsules 1.0 g,orally,3 times a day,1-5 d,Omepra-zole enteric-coated capsule 20 mg,orally,twice a day+ Clarithromycin tablets 0.5 g,orally,once a day+Metronidazole tablet 0.4 g,twice a day,6-10 d. All patients treated for 10 d. Effective rate of pain relief,relief time of pain and gastrointestinal symptoms, Hp eradication rate,recurrence after 12 follow-up and the incidence of adverse reactions in all groups were observed. RESULTS:Effective rate of pain relief and Hp eradication rate in group C were higher than group B,followed by group A,relief time of pain and gastrointestinal symptoms,recurrence rate in group C were lower than group B,which was lower than group A,with signifi-cant differences (P0.05). CONCLUSIONS:Taking omeprazole in stages combined with antibiotics can effectively relieve abdominal pains,shorten disease course,improve Hp eradica-tion rate,reduce long-term recurrence rate in the treatment of active chronic gastritis with Hp infection,with good safety.
