The average recoveries were 97.73%, 96.81%, 97.78%, 97.55%, 96.86%, 98.60%, 97.77%, 98.04% and 97.89%, respectively; the relative standard deviations were 0.70%, 1.1%, 2.3%, 2.1%, 1.3%, 1.4%, 2.3%, 1.6% and 1.9%, respectively. This method was used to determine the contents of nine active ingrients in 5 batches of Belamcandae Rhizoma.Conclusion The method is accurate and reliable, which can be used for the quality control of Belamcandae Rhizoma.
ABSTRACT
Based on the innovation of modern science and technology and concepts,the study of innovative Chinese medicine research has not been divorced from the traditional thinking of natural medicine research,in the theoretical system of traditional Chinese medicine,there was basically no inheritance and lack of innovation,which made the research of new medicine of traditional Chinese medicine fall into an awkward position.We sum up our experience in 1 1th Five-Year and 12th Five-Year,combined with the upcoming 13th Five-Year of the research and development idea of component Chinese Medicine,analyzed the impact of 3 aspects on the modernization of Chinese traditional medicine and put forward the solving methods.① The scientific screening of high-level candidate prescriptions has always been the bottleneck of the development of new Chinese medicine and the basic premise of modernization of Chinese Medicine;② It is an important outlet and measure to promote the modernization of traditional Chinese medicine to vigorously carry out the research on the transformation of traditional Chinese medicine and to formulate a scientific and rational mode of transformation of traditional Chinese medicine;③ From the point of view of the development and reform of component traditional Chinese medicine,it is necessary to follow the basic theory of traditional Chinese medicine,and comprehensively to consider the characteristics of the components of Chinese medicine,and to lay the foundation for the screening and research and development of Chinese herbal medicines
ABSTRACT
Translational medicine means that to establish a bridge between fundamental research and clinical medicine through bidirectional translation path in order to promote the translation and application from fundamental research to clinical medicine.The purpose of traditional Chinese medicine (TCM) translational model is to collate and build one multidimensional TCM translational model,rationality carry out the research on TCM translation.Three paths have been confirmed,where are from literature research to clinical verification,from clinical application to clinical verification,and from experiment to clinical verification.In this research,methodology of one path mcntioned above could be established,which is the key technology of translational medicine.Take constipation,insomnia,and post-flu cough as target diseases to investigate the herbal compounds which could be qualified for clinical application based on preliminary work.This research not only provided clinical data to TCM translation,but also established one methodology of TCM translation path--"from experiment to clinical verification".
ABSTRACT
This study was aimed to optimize Qinshuang particle best spray granulation process conditions. The or-thogonal test method was used with grain yield and baicalin transfer rate as the inspection indexes. The main in-fluence factors of Qinshuang particle spray granulation process were investigated. The results showed that the best technological parameters are atomization pressure of 1 800 Pa, inlet temperature at 90°C - 100°C, outlet temper-ature at 50 ° C - 60 ° C , and the extract relative density of 1 . 10 ( 60 ° C ) . It was concluded that the reasonable pro-cess conditions make particles with stable quality, which provide the experimental basis for industrial production.
ABSTRACT
Objective To study on the effects of Huaweishu granule on cisplatin-induced Beagle dog vomiting models and its mechanism.Methods Cisplatin-induced Beagle dog vomiting models were adopted as research object.The changes of vomiting frequency,latency,serum motilin content in the medulla oblongata and ileum,5-HT and substance P content of these models after using Hua weishu Granule were observed.Results ① Latent period of vomiting of the model group was (60.8±37.1)min; while this period was (137.3± 53.4)min,(122.8 ± 50.7) min,(l16.8±44.6)min,in the Huawei-shu low,medium and high dose group respectively,all showing a statistic difference than the model group (P＜0.05).②Frequency of vomiting in the model group was (270.3±51.8),while this frequence was (111.5±45.0) and (149.5±26.8) in Huawei-shu low and medium dose group respectively; ③ serum motilin in the model group was (0.354±0.098)ng/ml,while serum motilin in Huawei-shu low,medium and high dose group was (0.230±0.074) ng/ml,(0.235± 0.071) ng/ml,and (0.245± 0.062)ng/ml respectively,all lower than the model group (P＜ 0.05).④ Medulla oblongata 5-HT in the model group was (2.028 ±0.198)ng/ml,while medulla oblongata 5-HT in Huawei-shu low,medium and high dose group was (1.620±0.329)ng/ml,(1.194±0.386)ng/ml,and (1.269 ± 0.251) ng/ml respectively,all were lower than the model group (P＜0.05); ileum 5-HT in the model group was (1.634± 0.221)ng/ml,while ileum 5-HT in Huawei-shu low,medium and high dose group was (1.108±0.291)ng/ml,(1.194±0.386)ng/ml,and (1.269 ± 0.251) ng/ml respectively,all were lower than the model group(P＜0.05) ;⑤ ileal substance P content of the model group was (0.356±0.063)ng/ml,while ildeal P content in Huawei-shu low dose group was (0.274±0.064)ng/ml,lower than the model group than(P＜0.05).The medullary substance P content was (0.432±0.021)ng/ml in the model group,while medullary P content in Huawei-shu low,medium and high dose group was (0.370±0.040) ng/ml,(0.385±0.029) ng/ml,and (0.386± 0.041)ng/ml respectively,all were lower than the model group(P＜0.05).Conclusion Huawei-shu granule can prevent cisplatin-induced Beagle vomiting.
