Objective: To explore the relationship between lifestyle and ankle-brachial blood pressure. Methods: Ankle-brachial blood pressures of 2121 adults from all over China were measured with self-developed KD-991 portable ankle-brachial blood pressure simultaneous detecting instrument. They were divided into smoking group and no smoking group, heavy drinking group and moderate drinking group, exercise group and lack of exercise group and comparisons of abnormal ankle-brachial index (ABI, ≤0.9 or≥1.3) rate between paired two groups were performed. Results: Rate of abnormal ankle-brachial index (ABI, ≤0.9 or≥1.3) in smoking group (15.3%), heavy drinking group (13.6%) and lack of exercise group (10.5%) were significantly higher than those of no smoking group (7.9%), moderate drinking group (7.5%) and exercise group (7.4%) respectively, P<0.05 all. Conclusion: Unhealthy lifestyle is related to abnormal ankle-brachial blood pressure and it is very good to prevent occurrence of atherosclerosis , early discover and effectively control its development using ABI to guide people to change unhealthy lifestyles.

Simultaneous distillation-extractor was used for extracting the volatile substances in Phellodendron chinense Schneid.41 Volatile components were identified by gas chromatography/mass spectrometry (GC/MS) method. Of them the main components are ketones(16.38%),aldehydes(13.94%),alcohols(8.27%),phenols(50.38%),esters(3.02%),acids(2.18%).The content of the 41 identified compounds makes up 97.50% of the total volatile substances detected

Objective To establish the method of determination for rhein, emodin, chrysophanol and physcion in Niuhuang Qinghuo Pills. Methods Sample was hydrolyzed by 20% H2 SO4 , and anthraquinones were extracted by soxhlet extraction with acetone as solvent, and were determined by HPLC with Kromasil C18 as column, methanol-0.5%H3 PO4 (75:25,V/V) as mobile phase at the flow of 1.0 mL/min, 230 nm as the detection wavelength.Results The linear relationship of rhein, emodin, chrysophanol and physcion were 1.50-150, 0.950-95.0, 1.30-130 and 1.15-115 mg/L. The anthraquinones were seperated completely, the recovery of 4 anthraquinones were 98.14% -101.3%.Conclusion This method is simple, accurate, steady, and could be used for the quality control of Niuhuang Qinghuo Pills.
