ABSTRACT

To systematically evaluate the efficacy and safety of Ningxinbao Capsules in treatment of arrhythmia by Meta-analysis. Randomized controlled trial(RCT) or quasi-randomized control trial(Quasi-RCT) on Ningxinbao Capsules treating arrhythmia were obtained by computer-based retrieval in CNKI, Wanfang, VIP, SinoMed, PubMed, Web of Science, Cochrane Library and EMbase as well as manual retrieval, with time limit from database establishment to April 7, 2020. According to the inclusion and exclusion criteria of trials, all RCTs were screened and evaluated. Then the effective data were collected and RevMan 5.3 Meta-analysis software was used for analysis. Thirteen trials were included, involving 1 379 patients in total. Ningxinbao Capsules combined with anti-arrhythmia Western medicine were adopted as the intervention, and the patients in control group were treated with the anti-arrhythmia Western medicine alone. Meta-analysis results showed that as compared to control group, Ningxinbao Capsules combined with anti-arrhythmia Western medicine group was superior in clinical efficacy, dynamic electrocardiogram and average heart rate in patients with bradycardia, with indicated statistically significant differences. Ningxinbao Capsules had fewer adverse reactions and could relieve the toxic and side effects of anti-arrhythmia medicine possibly. The study showed that Ningxinbao Capsules played a role in treatment of arrhythmia and was relatively safe. However, due to the limited quality of the included studies, high-quality clinical trials are needed to verify the conclusions.

ABSTRACT

OBJECTIVE: To establish a quality evaluation method of Ningxinbao capsules based on HPLC fingerprint, quantitative analysis of multi-components and chemometrics. METHODS: The fingerprint of Ningxinbao capsules was established by HPLC. Six common peaks were identified as uracil, hypoxanthine, uridine, adenine, guanosine, and adenosine by comparison with reference substances, and their contents in samples were simultaneously determined. The chemometrics methods such as hierarchical clustering heat map analysis and principal component analysis were used to evaluate the quality of Ningxinbao capsules from different manufacturers based on the results of fingerprint and content determination. RESULTS: The similarity of samples from 27 different manufacturers ranged from 0.656 to 0.997. Hierarchical clustering heat map analysis and principal component analysis showed that the samples from 27 different manufacturers were clearly divided into two categories. The main influencing factors were fingerprint similarity and the contents of uridine, guanosine and total nucleosides. Different sources of raw materials were the main reasons for the quality differences between samples from different manufacturers. The purity of strain in raw materials was the key factor affecting the quality of Ningxinbao capsules. CONCLUSION: The method is accurate and reliable, and it can be used to control and comprehensively evaluate the quality of Ningxinbao capsules.

ABSTRACT

Objective:To study the HPLC fingerprint of Ningxinbao capsules, and establish a method for the simultaneous content determination of uracil, uridine, adenine and adenosine. Methods: The separation was carried out on an Agilent Zorbax SB-Aq C18 column(250 mm × 4. 6 mm, 5μm) with gradient elution using methanol-0. 05 mol·L-1 potassium dihydrogen phosphate at 30℃ and at a flow rate of 1. 0 ml·min-1 , the detection wavelength was 212 nm for fingerprint and 260 nm for the determination of the four nu-cleosines. Totally 10 batches of samples were analyzed with the developed HPLC fingerprint and the determination method, the data calculation was performed with similarity evaluation system in the chromatographic fingerprint of TCM. Results: In the fingerprint, 10 common peaks were marked and the separation of the four nucleosines was good. Conclusion:The method is simple and reliable. The HPLC fingerprint and contents of the four nucleosines in Ningxinbao capsules can be used for the quality control.

ABSTRACT

AIM:To establish HPLC method for making a assay of nucleosines in Ningxinbao Capsules(Cepha-(lospovium) sinensis Chen.sp.nov). METHODS:The assay was performed on a C_(18) column(4.6 mm?250 mm,5 ?m).The mobile phase was composed of phosphate buffer(pH 7.8-8.0)-acetonitrile(83∶17).The flow rate was at 1.0 mL/min.The detection wavelength was at 260 nm. RESULTS:The linear ranges of uridine,adenosine and inosine lay in the concentration range of 4.168-83.36,4.480-89.60,5.230-104.6 ?g/mL,respectively(r=0.999 9). The average recoveries were 0.4%,1.8%,2.5%,respectively. CONCLUSION:The method is simple,rapid.It is suitable for the assay of nucleosines in Ningxinbao Capsules.
