Building model from calibration set obtained good results, and vali-dated by prediction. According to heat-clearing and detoxicating oral liquid from 30 batches of 6 factories, the correlation coefficient of chloro-genic acid and baicalin model are 0.9993 and 0.9923, The root mean square error of cross validation (RMSECV) are 0.467 and 0.480, and the standard Error of prediction (SEP) of chloro- genic acid and baicalin are 0.356 and 0.370 re-spectively. The correlation coefficients in pre-diction set are 0.9997 and 0.9969, prediction results are accurate and reliable. This method can be applied in rapid analysis of heat- clearing and detoxicating oral liquid, and it is fit for on-line detection and has a wide application prospect.展开更多

Methods： Adopted was randomized double-blinded and placebo-parallel-controlled method, with 72 HIV/AIDS patients randomly divided into the ZY-4 group （36 patients） treated with ZY-4 and the control group （36 patients） treated with placebo. The treatment course was six months. The index of OD4^＋, OD8^＋ counts, body weight, clinical symptom scoring were estimated at 4 time points （0, 1, 3 and 6 month in the course）, and also the viral load before and after treatment. The whole course of observation was completed in 63 patients, 30 in the ZY-4 group and 33 in the control group. Results： OD4^＋ count in the ZY-4 group got elevated by 7.70 4±150.96/mm^3 on average, while that in the control group lowered by 27.33 4±85.28 /mm^3 . Fifteen out of the 30 patients in the ZY-4 group had their OD4^＋ count increased, which was evidently much higher than that in the control group （8/33, P〈0. 05）, suggesting that the efficacy of ZY-4 is superior to that of placebo in elevating OD4^＋ count. Moreover, ZY-4 showed actions in elevating OD45RA^＋ and OD8^＋ count, reducing HIV virus load, improving clinical symptom/sign and increasing body weight of patients. No obvious adverse reaction was found in the clinical trial. Conclusion： ZY-4 has an immunity-protective and/or rebuilding function in HIV/AIDS patients in the early and middle stage, and also shows effects in lowering viral load, increasing body weight and improving symptoms and signs to a certain degree.展开更多
