目的:提供一种评价多组分中药的基于数学集合的释药动力学方法.方法:以扶正化瘀方为研究模型,通过建立的基于数学集合的释放动力学评价方法指导扶正化瘀复方释药系统的制备,对其多组分释放特征进行量化评价,并采用Kalman滤波法验证方法的准确性.结果:两者比较结果均表明,扶正化瘀复方释药系统样本4与参比制剂扶正化瘀胶囊显示出释药同步.结论:此结果不仅验证了基于集合的方法的准确性和合理性,而且通过异步系数参数整体表征目标制剂的释放情况,并能从各特征峰信息的相对误差参数中找到释药单元剂量调整改进的方向,指导相关成分有目的性地调整,以使目标制剂满足与参比制剂释药同步性的要求,同时为多组分中药复方制剂的定量表征和评价中药多组分释放行为的同步性提供一种行之有效的评价手段. 相似文献

应用化合物组释放动力学方法评价银翘解毒片的释放特征 总被引:3,自引:0,他引:3
目的:考察中药化合物组释放动力学新理论在银翘解毒片释放特征评价中的适用性。方法:以Kalman滤波法为基础,进行紫外分光光度法测定银翘解毒片化合物组标准谱、线性、精密度、稳定性等方法学研究,测定银翘解毒片及其粉末的化合物组释放特征。结果:方法学结果表明,在0.112~1.120mg生药/mL范围内银翘解毒片化合物组呈线性相关(r=0.9997);高、中、低化合物组浓度测定的RSD分别为0.05%、0.07%和0.31%,浓度分别为0.278,0.556,和1.120mg生药/mL的供试液化合物组在24h内稳定。结论:化合物组释放度能简洁、可视、直观地反映银翘解毒片多组分释放动力学特征,中药化合物组释放动力学新理论可以定量地揭示传统中药制剂的新内涵或其给药系统的活性组分释放特征。 相似文献

Traditional Chinese medicine(TCM) has been widely used in many oriental countries for thousands of years and played an indispensable role in the prevention and treatment of diseases, especially the complicated and chronic ones. It is a very complex mixture containing hundreds or thousands of different components. Pharmacokinetic study on active constituents in TCM preparations is a good way for us to explain and predict a variety of events related to the efficacy and toxicity of TCM. In the drug discovery phases, pharmacokinetics is a key to guide medicinal chemists in the optimization process of a chemical series and to assist pharmacologists to design in vivo studies.To explore the potentially bioactive components in TCM, it is necessary to further study the in vivo pharmacokinetic characteristics of multiple absorbed components and find out the optical time-course behavior to providing more substantial research for new leads in drug discovery. Pharmacokinetics screening method could provide a reliable means of prospecting natural products in the search for new leads in drug discovery. This review summarizes the research progress of PK on TCM in the search for suitable lead compounds in recent years. 相似文献

Metabolomics Deciphering Therapeutic Effects and
Mechanism of Traditional Chinese Medicines 下载免费PDF全文
Wei-Wei M Ai-Hua Zhang Hui Sun Xiang-Cai Meng Xi-Jun Wang 《World Journal of Traditional Chinese Medicine》2016,2(3)
Traditional Chinese medicine(TCM),an ancient medical system,has the advantages of multi-targeting and multi-ingredient preparations,and is different from modern pharmacology.However,because of the complexity of TCM and the limitation of present investigation method,the research for deciphering the scientific basis and systematic features of TCM is difficult to go further.Metabolomics has a significant increased study in recent years and enables mapping of early biochemical changes in disease and hence provides an opportunity to develop predictive biomarkers.Moreover,its method and design resemble those of traditional Chinese medicine.Therefore,it can provide useful tools for exploring essence of TCM,and will help to in-depth understand Chinese medicine syndromes.In this mini-paper,particular attention will be paid to the past successes in applications of robust metabolomics to contribute to small metabolites discovery in TCM development. 相似文献

〔摘 要〕 目的:观察中药内服联合中医手法复位治疗闭合性前臂骨折的临床疗效。 方法:选取漳州市漳浦中医院2022 年 1 月至 2022 年 12 月收治的 66 例闭合性前臂骨折患者,按照是否实施中药内服联合中医手法复位治疗将患者分为对照组(中医手法复位治疗)与观察组(中药内服联合中医手法复位治疗),每组 33 例,比较两组患者治疗效果。 结果:观察组患者治疗后 3 d、7 d、14 d 的视觉模拟评分法(VAS)评分低于对照组,差异具有统计学意义(P < 0.05);观察组患者并发症总发生率低于对照组,差异具有统计学意义(P < 0.05);治疗 3 个月后,观察组患者尺偏角、掌倾角、前臂旋前、前臂旋后度均高于对照组,差异具有统计学意义(P < 0.05);观察组患者总有效率高于对照组,差异具有统计学意义(P < 0.05)。 结论:闭合性前臂骨折患者中药内服联合中医手法复位治疗效果优于单一中医手法复位治疗。 相似文献
