ABSTRACT
Objective:To explore anti-platelet/anti-coagulation treatment and their influence on prognosis in advanced aged patients with acute coronary syndrome (ACS)complicated atrial fibrillation (AF)after percutaneous coronary intervention (PCI).Methods:A total of 204 advanced aged ACS + AF patients treated in our heart center were se-lected.All patients received CHA2 DS2 Vasc score assessment,male had score ≥2 scores and female had score ≥3 scores.A total of 160 cases received dual anti-platelet therapy combined anticoagulant treatment of warfarin,and they were randomly divided into low intensity group [n=80,international normalized ratio (INR)remained 1.8~2.3]and high intensity group (n=80,INR remained 2.3~2.8),both groups were followed up for 18 months.Inci-dence rates of major adverse cardiovascular and cerebrovascular events (MACCE),ischemic and hemorrhage events were observed.Results:Both groups were followed up for a mean 18 months,and there were no significant differ-ence in all-cause mortality,incidence rates of MACCE and fatal hemorrhage between two groups,P > 0.05 all.Compared with low intensity group,there were significant rise in incidence rates of severe hemorrhage (3.8% vs. 12.5%),P <0.05.Conclusion:Low intensity warfarin anticoagulant therapy can effectively reduce incidence rates of MACCE and ischemic events,and incidence rate of hemorrhage events is low in advanced aged ACS + AF pa-tients after PCI.

ABSTRACT
OBJECTIVE: To investigate the chemical constituents in the roots of Allium tuberosum. METHODS: Colum chromatography with different materials such as silica gel was used to isolate and purify the chemical constituents. Their structures were identified by spectroscopic analysis. RESULTS: Nine compounds were isolated from the roots of Allium tuberosum and their structures were identified as 4,8-dihydroxyacetophenone-8-O-ferulate(1), 4,8-dihydroxyacetophenone(2), 3,4,5-trimethoxybenzoic acid(3), 3,4,5-trimethoxycinnamic acid(4), buddlenol D(5), E-1,6,11-triene-4,5,9-trithiadodeca-9,9-dioxide(6), tianshic acid(7), daucosterol(8), and linoleic acid(9). CONCLUSION: Compound 1 is a new compound and compounds 2-5 are obtained from Allium tuberosumfor the first time.
