Traditional Chinese medicine(TCM) injection,which plays a unique role in the clinical treatment,is Chinese original dosage form.But in recent years due to its quality problems or unscientifically clinical use,some adverse reactions have reported,even several injections had serious adverse reactions.So how to develop TCM injection becomes one of the topics the public and scholars most concerned about.Therefore,the three "bottleneck" problems of TCM injection on the current development,which are the material basis and TCM theory,clinical efficacy and safety,and also quality control,were analyzed and discussed in the article.Then the countermeasures were proposed and provided ideas for future research and development of TCM injection.
ABSTRACT
Objective Comparing the serum fingerprint of four kinds of extract solution from Banxia Baizhu Tianma Decoction.Methods Taking rabbits as experiment animals,collecting blood,and separating serum after drenching semi-bionic enzyme extracting(SBEE) solution.HPLC was used to detect the fingerprints of medicated serum at different blood-collecting time in order to optimize the best blood collecting time,then the serum fingerprints of four kinds of solution collected were compared.Results HPLC showed that when blood collecting time was 2 h,the number and total area of chromatographic peak had the maximum value;SBEE Solution had the the maximum number and total area of chromatographic peak in the four kinds of solution at the best blood collecting time.Conclusion The component content in SBEE medicated serum is higher than that by other method.

ABSTRACT
Objective: To establish the quality standard for Huahaiyigan Effervescent Granules. Methods: Astragalus membranaceus(Fisch) Beg., Bupleurum chinenes DC., Polygonum cuspidatum Sieb. et Zucc. and Schisandra chinensis(Turcz.) Baill. were identified by TLC; and the content of schisandrin B was determined by HPLC. Results: Astragalus membranaceus(Fisch.) Beg., Bupleurum chinenes DC., Polygonum cuspidatum Sieb. et Zucc. and Schisandra chinensis(Turcz.)
