Objective: To develop an HPLC method for the simultaneous determination of five active components ( 5-O-methyl-visammioside, prim-O-glucosycimifugin, hesperidin, rosmarinic acid and forsythin) in Sijiganmao tablets. Methods:The samples were separated on an Agilent C18 column (250 mm × 4. 6 mm,5 μm) by acetonitrile-0. 1% formic acid solution with gradient elution. The detection wavelength was 283nm,the flow rate was 1. 0μl·min-1 ,the column temperature was 30℃,the detection wavelength was 283 nm,and the sample size was 10μl. Results:The complete separation was obtained for the five active compounds. The five regression e-quations showed good linear relationships. The average recoveries of the compounds were between 95. 0% and 105. 0%. Conclusion:The established method is accurate, reliable, simple and effective, which can be used in the quality control of Sijiganmao tablets.

Objective:
To investigate the safety and efficacy of Warfarin combined with Aspirin in the treatment of multiple medium and giant coronary artery aneurysms in Kawasaki disease(KD).
Methods:
Clinical and follow-up data of 45 children diagnosed with KD complicated with multiple medium-sized and giant coronary artery aneurysms from April 2014 to December 2018 at Guangzhou Women and Children′s Medical Center were collected.These children were divided into 2 groups.A total of 31 cases received regular oral Warfarin combined with Aspirin called experimental group.There were 14 patients treated with oral Aspirin and Clopidogrel called control group.General information, laboratory examination, electrocardiogram, echocardiography, outcome and bleeding complications of the 2 groups were analyzed retrospectively.
Results:
(1) In experimental group, there were 22 patients found thrombosis under echocardiography.The 10 patients′ thrombosis disappeared, 5 patients′ thrombosis reduced, and 2 patients′ increased after treatment.In control group, there were 5 cases found thrombosis.The 2 cases′ thrombosis reduced and 3 cases′ throm-bosis increased.The number of thrombosis in experimental group was significantly reduced, and the number of new thrombosis was less than that in control group (
