Objective To observe the effect of Shuxuening Injection NO, NOS, SOD and MDA on of angina pectoris patients. Methods 100 patients with angina pectoris were randomly divided into two groups. 50 patients in treatment group were treated with Shuxuening Injection, 5 mL once, drop into 250 mL 5% glucose injection (it change into 250 mL 0.9% sodium chloride injection if the patient have diabetes), one time a day. 50 patients in control group were treated with isosorbide mononitrate injection, 60 mg once, drop into 250 mL 5% glucose injection (it change into 250 mL 0.9% sodium chloride injection if the patient have diabetes), 15 gtt one minute, one time a day. Results NO, NOS and SOD of the treatment group were objective improved, and MDA objective reduced. NO improved from (47.61?8.76)?mol/L to (71.84? 13.26)?mol/L, NOS improved from (1.64?0.23)U/mL to (2.31?0.29)U/mL, SOD improved from (46.34? 5.62)U/mL to (64.54?9.10)U/mL, and MDA reduced from (8.96?1.76)U/mL to (6.71?1.43)U/mL. Total effective rate in improving angina pectoris was 96%, and ECG was 76%. The time (ischemic ST-T changes) of holter ECG was reduced from (130.45?18.61)min to (32.33?5.32)min, there was a significant difference between the two groups (P

OBJECTIVE To establish the fingerprints of Danggui buxue pills a nd the method for the content determination of three indicative constituents （ferulic acid ，calycosin 7-O-β-D-glucoside and astragaloside Ⅳ）. METHODS Fifteen batches of Danggui buxue pills from two manufacturers were analyzed by high performance liquid chromatography （HPLC）. The determination was performed on a Hypersil ODS 2 C18 column with mobile phase consisted of acetonitrile- 0.2％ formic acid （gradient elution ）at the flow rate of 1.0 mL/min. The column temperature was set at 25 ℃，and the sample size was 20 μL. UV detector [detection wavelengths were 250 nm （calycosin 7-O-β-D-glucoside），323 nm （ferulic acid ）] and evaporative light scattering detector （astragaloside Ⅳ）were selected as detectors. HPLC fingerprints of 15 batches of Danggui buxue pills were established with Similarity Evaluation System of TCM Chromatographic Fingerprint （2012 edition）. The chromatographic peaks were identified and assigned by comparing with the chromatogram of the reference substance and reference medicinal material ；the contents of ferulic acid ，calycosin 7-O-β-D-glucoside and astragaloside Ⅳ were also determined. RESULTS There were 33 common peaks in the fingerprints of 15 batches of samples with the similarities not lower than 0.893. Ferulic acid and calycosin 7-O-β-D-glucoside were identified as peak 13 and 15，respectively. Compared with the chromatogram of reference medicinal material，it could be found that peaks 1-3，7，8，10，12，13（ferulic acid ），17-19，27-29，32 and 33 belonged to Angelica sinensis，and peak 14，15（calycosin 7-O-β-D-glucoside），20-23，25 belonged to Astragalus membranaceus . The methodology of content determination met the requirements. The mean contents of ferulic acid ，calycosin 7-O-β-D-glucoside and astragaloside Ⅳ in 15 batches of samples were 0.050 1，0.402 6，0.913 4 mg/g. CONCLUSIONS In this study ，HPLC fingerprints of Danggui buxue pills and the method of HPLC quantitative analysis for three indicative constituents are established. Established methods are accurate，reliable and repeatable.
