ABSTRACT
Objective:To investigate the clinical efficacy of the Guanxinning tablet on the prethrombotic state in older adults with stable angina pectoris.Methods:In this study, 80 elderly patients with coronary heart disease and blood stasis admitted to our hospital between December 2019 and December 2021 were selected as the study subjects, and were randomly divided into a control group and an observation group(40 cases each). The control group was treated with Aspirin alone, and the observation group was treated with the Guanxinning tablet in addition to aspirin.Differences in traditional Chinese medicine(TCM)syndrome scores, weekly angina attacks and intervals between attacks, von Willebrand factor(vWF), thrombomodulin(TM), and granule membrane protein-140(GMP-140)levels between the two groups were compared.Results:There was no statistically significant difference in TCM syndrome scores between the observation group and the control group before treatment(11.34±2.2 vs.11.8±2.3, t=0.184, P=0.856), but there was a statistically significant difference between the observation group and the control group after treatment(6.5±1.8 vs.8.4±2.0 points, t=4.230, P=0.000). The number of weekly angina attacks and the interval between attacks in the observation group were significantly decreased compared with the control group, and the difference was statistically significant(all P<0.01). The levels of molecular markers of the prethrombotic state(vWF, TM and GMP-140)in the observation group were more favorable than those in the control group, with statistical significance(all P<0.05). Conclusions:The Guanxinning tablet can improve angina pectoris symptoms in elderly patients with coronary heart disease and effectively improve the expression of molecular markers of the prethrombotic state.

Objective To establish the quality control of Yinhuang tablet (YHT) by using sever ingredients determina-tion and tri-wavelength fingerprint analysis technologies. Methods The chromatographic fingerprints were developed by using Agilent Poroshell 120 SB C18(4. 6 mm×150 mm, 2. 7 μm) as the separation column and 0. 2% H3 PO4-methanol as the mobile phase. The flow rate was 0. 5 mL·min-1 , the UV absorbance was monitored at 214, 278 and 326 nm by injecting 5 μL of the sample solution and the column temperature was maintained at (35. 00±0. 15) ℃ . The chromatographic fingerprints were charac-teristically evaluated for quality ranking of 13 batches of YHT by the 4. 0 software of the digitized evaluation system of traditional chinese medicine fingerprint with the super information characteristics. Seven marker compounds including chlorogenic acid, caf-feic acid, baicalin, wogonoside, baicalein, wogonin and scutellarin were simultaneously determined to compare the variation a-mong five different manufacturers. Results The tri-wavelength fingerprint high performance liquid chromatography method was established. A total of 28(214 nm),29(278 nm)and 26(326 nm)common peaks were identified at respective wavelengths, using baicalin (BCL) as the referential peak. The software was applied to evaluate the YHT-HPLC fingerprints and identify the quality of 13 batches of YHT by systematically quantified fingerprint method (SQFM). The results showed that the content from the dif-ferent manufacturers varied greatly. Conclusion The quality of YHT varies between different makers, and is necessary to es-tablish the criterion for quality control. This method can provide a new reference for the quality control of YHT.

ABSTRACT
AIM: The method of the double qualitative similarities and the double quantitative similarities was carried out for the evaluation of the chromatographic fingerprints and applied to HPLC fingerprints of Rhizoma anemarrhenae. METHODS: The chromatographic fingerprints were obtained by injecting 5 ?L of the sample solution each time on a CenturySIL C_(18) BDS column(20 cm?4.6 mm,5 ?m) with the gradient elution solvent system composed of 1% acetic acid-water and 1% acetic acid-acetonitrile.The column temperature was maintained at(30?0.15) ℃ and the detection wavelength was set at 265 nm.The chromatographic fingerprints were evaluated by the normalized similarity S_F and normalizing similarity S′_F and the projecting similarity C% and quautitative similarity P%, changes in characteristics were investigated in the cases of big peaks-free and small peaks-free respectively. RESULTS: 21 co-possessing peaks were selected as the fingerprint peaks of Rhizoma anernarrhenae by choosing rutin peak as the reference peak.S_F could clearly reflect the chemical constituent distribution,and C% could reflect the total contents of the sample,but both of them were seriously influenced by the big peaks and could not reflect the missing of small peaks.S′_F and P% were equivalent weight to all fingerprint peaks,and they could reflect sensitively the small peaks drop-out. CONCLUSION: The double qualitative similarities and the double quantitative similarities are composed of S_F,S′_F,C% and P%,so the changes or lacks of both big peaks and small peaks can be punctually simultaneously monitored to be a novel method for evaluating fingerprints.The HPLC fingerprints can be useful in the quality control of Rhizoma anemarrhenae.
