Application of Best Subsets Regression on the risk classification for Spermophilus Dauricus Focus / 中华流行病学杂志

<p><b>OBJECTIVE</b>To study the risk classification of animal plague in Spermophilus Dauricus Focus, using the Best Subsets Regression (BSR) model.</p><p><b>METHODS</b>Matlab, BSR and exponential smoothing were employed to develop and evaluate a model for risk classification as well as to forecast plague epidemics at the Spermophilus Dauricus Focus. Data was based upon the Inner Mongolia surveillance programs. This model involved 7 risk factors, including density of Spermophilus dauricus, percentage of hosts infested, host flea index, percentage of nests infested, nest flea index, percentage of runways infested, and runway flea index.</p><p><b>RESULTS</b>Forecasting values of the classification model(CM)were calculated and grouped into 3 risk levels. Values that over 2/3 of the CM would indicate the existence of potential epidemics while those below 1/3 would indicate that there were no risk for epidemics but when values that were in between would indicate that there exist for high risk. Annually, during the observation period in the Inner Mongolia Spermophilus Dauricus Foci, the detection of Yersinia pestis gave a risk rating value of 1 which stood for existing epidemics, while nil detection rate generated a 'zero' value which representing the situation of non-epidemic. The overall plague epidemics forecasting surveillance programs in 2012 at the Spermophilus Dauricus Foci indicated that no active plague was observed. When the forecasting values became over 2/3, combinations of all the risk factors would achieve the consistency rates of 100%. When the forecasting values were below 1/3, combinations of at least the first 4 factors could also achieve the consistency rates of 100%. However, when the forecasting values fell in between, combinations of at least the first 4 factors would achieve the consistency rates of around 50%.</p><p><b>CONCLUSION</b>Results from our study showed that plague would not be active to become epidemic, in 2012.</p>

Research of Quality Evaluation Method of Liyan Dan Complex Pharmaceutics by Biological Effect Ratio / 现代生物医学进展

Objective: To determine biological effect ratio (BER) on anti-herpes simplex virus-Ⅰ (HSV-Ⅰ)of Liyan Dan (LYD) complex pharmaceutics and its active components alignment (ACA), and to discuss the new identification method of Chinese patent medicine expressed by standard BER. Methods: Protective effect to cells infected by HSV-Ⅰ was evaluated by a 3-(4,5-dimethyl-2 thiazoyl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay. The ACA was determined by high performance liquid chromatography (HPLC) and ultraviolet spectrophotometry. By the protective percent (PP) to cells infected by HSV-Ⅰ of LYD and its ACA the BER was calculated. BERS= PPS / PPACA (protective percent to cells infected by HSV-Ⅰ of sample/protective percent to cells infected by HSV-Ⅰ of ACA; the concentration of sample was 2-x mg/mL). Results: LYD can inhibit cytopathogenic effect (CPE) and its BER was 1.16. Conclusion: BER and ACA of Chinese patent medicine can reflect connotation of Chinese patent medicine quality. This index described intrinsic quality of curative effect on Chinese materia medica.The new concepts of BER and ACA were pulled into the study. This research offered a new train of thought and method to study Chinese patent medicine quality as follows. Firstly, establish standard biological effect of ACA as a standard of effect; secondly,measure the biological effect of sample by the method of measuring effective standard of ACA; thirdly, calculate BER according to the formula (BERS=PPS/PPACA). Standard of BER on quality evaluation is as follows. If 1 ≥ BERS ≥ 0.9, the sample is eligible; if BERS＞1, the sample is of high quality; if BERS＜0.9, the sample is disqualification. This quality evaluation method is much more scientific than the method that evaluate quality only by one or two components contents.
