ABSTRACT
Idiosyncratic hepatotoxicity of Polygonum multiflorum has attracted a great attention in the world. The most toxic part of idiosyncratic hepatotoxicity was screened by MTT assay and flow cytometry, which was the 50% ethanol elute by macroporous adsorptive resins from alcohol-extraction of P. multiflorum. The fingerprints were collected by HPLC from 50% ethanol elute of crude and processed P. multiflorum from different habitats, then 14 common peaks were determined. Spectrum-toxicity relationship was analyzed by rough set theory(RST). Two main chemical components were predicted for idiosyncratic hepatotoxicity, in which TSG was the greater contributor. Idiosyncratic hepatotoxicity of TSG was tested in vitro, and the results indicated that TSG was the most important constituent contributed to idiosyncratic hepatotoxicity of P. multiflorum. The study showed the discovery of the main chemical components for idiosyncratic hepatotoxicity, and RST was effective for analyzing the spectrum-toxicity relationship, which could be a new method used in the effective/toxic constituents field of traditional Chinese medicine.

Objective To survey the correlation among ADR performances of Shuxuening injection(SXN injection ) based on ADR reports and literature data by rough set theory(RST). Methods By collecting 468 ADR reports of SXN injection,data attribute reduction were processed by Rossata software,and the generated rules and each indicator were analyzed. Results 9 main indicators,which mainly belongs to medication information,had a strong relationship with ADR.There was a correlation among ADR performances.Relationship could also found between performances and medication information. Conclusion The results of the study provide reference for clinical reasonable application of SXN injection,and enrich the research method of ADR.
ABSTRACT
Objective To establish an evaluation index system of electricity saving at general hospitals.Methods Based on civil building energy saving studies and in accordance with national regulations on hospital energy saving, the authors build an electricity saving index system for general hospitals.The indexes were reduced by the rough set theory, and their weight was determined by analytical hierarchy process and expert analysis.Results An electricity saving evaluation index system for general hospitals is so developed, consisting of six level-2 indexes and 27 level-3 indexes.Conclusions Such an evaluation index system can guide hospital electricity consumption and saving.
ABSTRACT
KDD has an abroad application foreground in hospital,espectially in HIS,clinical asistance,detection,and diagnosis.Some research achievements has been applied in hospital diagnosing and treatment.Such aspects of KDD are discussed as manual neural network,fuzzy system evolutionary algorithms,rough set,decision tree,support vector machine,etc.[Chinese Medical Equipment Journal,2008,29(2):74-75]
