Dynamic chromatopharmacokinetics model for components in Chinese medicine and validation in Buyang Huanwu Decoction / 中国中药杂志

The Chinese medicine is mostly derived from plants or animals, highly polymorphic, with dynamic components which are reflected by the characteristic peaks and fingerprint peaks in chromatographic fingerprints. The chromatopharmacokinetics method for determined components is not applicable due to dynamic changes of chromatopharmacokinetics. Based on the preliminary study, dynamic pharmacokinetics mathematical model for multiple components in Chinese medicine was set up and verified by Buyang Huanwu Decoction as the model drug, applying the principle of the total quantum statistical moment(TQSM), superimposing or subtracting the relevant statistical parameters in blood samples and blank samples. This provided a new method for the chromatopharmacokinetic study of Chinese medicine. HPLC was used to determine the TQSM parameters in blood and blank sample fingerprints of Buyang Huanwu Decoction at each point, and the overall TQSM parameters of drug-containing blood sample and blank samples were obtained with addition calculation of TQSM; while the initial TQSM of the pure drug can be obtained with subtraction calculation. The metabolic and absorption equilibrium constants were calculated iteratively to a steady state using the estimated metabolic equilibrium constants, then the metabolic chromatopharmacokinetic parameters in rats were obtained: VUC_T 1.262×10~8 mAu·s, MRT_T 37.48 h, VRT_T 9.016×10~2 h~2, CL_T 25.79 mL·h~(-1)·kg~(-1), Vs 1.586×10~2 mL·kg~(-1), t_(T,0.5) 6.15 h, respectively. This suggested that 95% of the compounds in whole recipe were metabolized and secreted from the body after 0-96.33 h. The experiment verified that the established mathematical model and the total quantum moment statistics parameters can represent the dose-time relationship of Buyang Huanwu Decoction, which can be used to study on in vivo metabolism dynamics for Chinese medicine.

Establishing The Measure Table of Emotion Evaluation of Female Experiment Macaque as Well as Its Stability and Validity Research / 浙江中医药大学学报

[Objective] Establish The Measure Table of Emotion Evaluation of Female Experiment Macaque, evaluate types of emotions of the female experiment macaque, provide the criterion of quantization evaluation for the emotion disease.[Methods] To collect and analyse the expression and action of macaque by observation, to establish The Screening Table of expression, action and emotion for the female experiment macaque; to set up the Mathematics Model by none-condition logistic regression, to provide explanation for establishing the Measure Table of Emotion Evaluation of Female Experiment Macaque; to set up The Measure Table of Emotion Evaluation of Female Experiment Macaque; to check up the stability and consistence of the measure table by test-retest and Split-Half means; to check up the stability of the criterion of validity by equivalence means; to evaluate the validity by criterion-related means.[Results] The Test-Retest Reliability of the indignation, depression, and enjoyment emotion is higher than the other, the Split-half Reliability of the indignation and depression emotion is higher than the others; the stability of the validity Criterion of all emotion is higher except for the anxiety emotion. The emotion integral can reflect all the emotion change; The Criterion-related Validity of the indignation, depression, friendliness and sex emotion is higher than the others. [Conclusion] Although the validity of the Measure Table is lower in anxiety emotion measuring, the interior consistence is not very good in friendliness and enjoyment emotions; the validity and stability about the other primary emotions reach the criterion of the Measure Table.
