Injections for traditional Chinese medicine have over 60 years of history of development and application. In recent years, however, their adverse reactions have been reported one after another. Consequently, studies on screening sensitinogens (sensibiligens) from injections for traditional Chinese medicine have drawn people's attention and become a tough problem all over the world. This essay analyzes the current state of studies on screening techniques of sensitinogens in injections for traditional Chinese medicine according their mechanism of immunotoxicity, and then proposes to adopt the synthetic immunoassay combining immunity bottle chip, immunity cover chip and immunity chromatographic fingerprint to screen sensitinogens from injections for traditional Chinese medicine, in order to build a safety evaluation barrier for development and clinical application of injections for traditional Chinese medicine.

OBJECTIVETo investigate the influence of molecular imprinting phenomena of traditional Chinese medicines (TCMs) on basic theories of TCMs according to current situations of molecular imprinting technology and experimental studies.

METHODFundamental principles of molecular imprinting theory were followed to analyze the material basis for TCM molecules to generate the imprinting phenomena, in order to find other material basis with more direct efficacy in line with the requirements of basic theories and modernization of TCMs.

RESULTCompared with single-component structures, TCMs and their compound components could create super-molecular compounds through complexation, composition, chelation, inclusion, neutralization, self-assembly and chemical reaction. The material basis of TCMs was super-molecular compounds including single ingredients, and there was an inter-molecule imprinting phenomenon. Therefore, special attention should be paid to inter-super-molecule imprinting actions in studies on TCM property, quality control, processing, drug preparation and pharmacology. The compatibility of TCM compounds could significantly change the action.

CONCLUSIONThe material basis of TCMs is super-molecular compounds based on single molecular groups. Super-molecules and molecular groups act rules, which is another difference between TCM compounds and single molecular drugs.

OBJECTIVESynthesis and identification of complete antigen of rutin, the traditional Chinese medicine active ingredient, and develop rapid detection of rutin using enzyme-linked immunoassay method (ELISA). Immunogenicity of the complete antigen was also studied.

METHODPrepare the complete antigen by sodium periodate solution and identified by UV scanning and SDS-PAGE test. Male New Zealand white rabbits were immunized by the antigen to obtain the antiserum.

RESULTThe results of UV analysis showed that the coupling ratio of complete antigen is 13: 1. SDS-PAGE display of the artificial antigen was delayed compared with bovine serum protein. The titer of rutin antibody is 1:4 000. The sensitivity of IC50 was 5.37 mg x L(-1), the lowest detection limit was 1 mg x L(-1), the average recovery was 102%, the intra and interspecific RSD were less than 10%, cross-reactivity rate of antibodies and other analogs were less than 1%.

CONCLUSIONRutin complete antigen was synthesized successfully, and the rapid detection of rutin by ELISA method was successfully established.

The qualitative and quantitative analysis on traditional Chinese medicine and formula components can be made by chemical and instrumental analysis methods. Of both, the instrumental analysis methods play a dominant role, including HPLC, HPLC-MS, HPLC-NMR, GC, GC-MS, biochemical and biological effect. But because traditional Chinese medicines and formula have complicated components, chemical methods are so unspecific that they shall be used less or with caution. While instrumental analysis methods are so specific that they are appropriate for analyzing complicated single component. The analysis techniques for multiple components of traditional Chinese medicines and formula focus on fingerprints, but all of these analysis techniques are limited by the pre-requisite of separation and the lack of general-purpose detectors and therefore being hard to realize the determination of all components of traditional Chinese medicines and formula. In the natural world, however, organisms identify native and alien components through specificity and non-specificity of clusters decided by antigens and antibodies. For example, components of traditional Chinese medicines are directly or indirectly synthesized into antigens and injected into animals, in order to generate specific antibodies and then collect cross reaction information of these components to specific antibodies. As for components without cross reaction, their contents shall be directly read out on the basis of the inhibition rate curve of competitive reaction for specificity of antigens and antibodies. Besides, a cross inhibition rate matrix shall be established first, and them a multiple regression linear equation between cross component concentration or concentration logarithm and inhibition rate by labeling the immunity competitive reaction between antibodies and haptens of traditional Chinese medicine and compound components, and then solved to obtain concentration of each component. The two results are combined to establish the synthetic immunity chip method for traditional Chinese medicine and formula components.
