Abstract:
In vitro cell experiment based on serum pharmacology is a common way to study the pharmacodynamic mechanism of Chinese medicine， and screening the optimal intervention concentration of serum containing Chinese medicine is a key step in the whole experiment. Over-diluted serum containing Chinese medicine or over-high concentration leads to false negative or positive results， while the optimal concentration of medicated serum reduces the number of groups in subsequent experiments as well as the operation error. Thus it is of great significance to screen the optimal serum concentration in studying the pharmacodynamic mechanism of Chinese medicine in in vitro cell experiments. However， there has been no unified standards for the screening methods at present. After reviewing the literature in China and abroad in the past 20 years， this paper conducted an analysis from three aspects of intragastric dose of Chinese medicine， blood collection time and serum dilution degree， and then summarized the screening methods for optimal concentration of serum containing drugs， providing guidance for the study of pharmacodynamic mechanism of Chinese medicine. The screening methods mainly included "same intragastric dose， same blood collection time， and different concentrations" "different intragastric doses， same blood collection time， and same concentration" "same intragastric dose， different blood collection time， and same concentration" "different intragastric doses， different blood collection time， and different concentrations" "serum lyophilized powder" "simulation of gradient concentration of serum containing western medicine" and "pure serum intervention". Among them， the former two were the dominant ways in current related research. The above screening methods had their own advantages and disadvantages， and researchers should make a reasonable choice according to the specific requirements and actual situation of the experiments.
