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

TP is specially used for the treatment of awkward rheumatoid arthritis, but its clinical application is confined by intense side effects. It is reported that licorice can obviously reduce the toxicity of TP, but the detailed mechanisms involved have not been comprehensively investigated. The current study aimed to explore metabolomics characteristics of the toxic reaction induced by TP and the intervention effect of licorice water extraction(LWE) against such toxicity. Obtained urine samples from control, TP and TP + LWE treated rats were analyzed by UPLC/ESI-QTOF-MS. The metabolic profiles of the control and the TP group were well differentiated by the principal component analysis and orthogonal partial least squares-discriminant analysis. The toxicity of TP was demonstrated to be evolving along with the exposure time of TP. Eight potential biomarkers related to TP toxicity were successfully identified in urine samples. Furthermore, LWE treatment could attenuate the change in six of the eight identified biomarkers. Functional pathway analysis revealed that the alterations in these metabolites were associated with tryptophan, pantothenic acid, and porphyrin metabolism. Therefore, it was concluded that LWE demonstrated interventional effects on TP toxicity through regulation of tryptophan, pantothenic acid, and porphyrin metabolism pathways, which provided novel insights into the possible mechanisms of TP toxicity as well as the potential therapeutic effects of LWE against such toxicity.展开更多

Although traditional processing methods can achieve detoxification effect as desired, there are some obvious drawbacks, including a significant loss of alkaloids and poor quality consistency. It is thus necessary to develop a new detoxification approach. In the present study, we designed a novel one-step detoxification approach by quickly drying fresh-cut aconite particles. In order to evaluate the technical advantages, the contents of mesaconitine, aconitine, hypaconitine, benzoylmesaconine, benzoylaconine, benzoylhypaconine, neoline, fuziline, songorine, and talatisamine were determined using HPLC and UHPLC/Q-TOF-MS. Multivariate analysis methods, such as Clustering analysis and Principle component analysis, were applied to determine the quality differences between samples. Our results showed that traditional processes could reduce toxicity as desired, but also led to more than 85.2% alkaloids loss. However, our novel one-step method was capable of achieving virtually the same detoxification effect, with only an approximately 30% alkaloids loss. Cluster analysis and Principal component analysis analyses suggested that Shengfupian and the novel products were significantly different from various traditional products. Acute toxicity testing showed that the novel products achieved a good detoxification effect, with its maximum tolerated dose being equivalent to 20 times of adult dosage. And cardiac effect testing also showed that the activity of the novel products was stronger than that of traditional products. Moreover, particles specification greatly improved the quality consistency of the novel products, which was immensely superior to the traditional products. These results would help guide the rational optimization of aconite processing technologies, providing better drugs for clinical treatment.展开更多

Methods： A total of 142 patients were assigned to the Trilogy Detoxicating Therapy group （the treatment group, 82 patients） and the Western medicine treatment group （the control group, 60 patients）. All of the patients were treated with NovoNorm 1 mg and metformin hydrochloride tablets 0.15 g thrice per day for lowering the blood glucose, as well as Perindopril 4 mg twice daily for lowering blood pressure, recombinant human erythropoietin 2 000 U and a hypodermic injection thrice a week for rectifying anemia, 30 days as one course of treatment, and all patients were treated for two courses. Patients in the treatment group were treated with the Trilogy Detoxicating Therapy [dispersing the five-zang （脏） organs, expelling toxins through colonic dialysis and skin dialysis fumigation] in addition to the aforementioned drugs. Parameters observed and recorded in the study included renal function [serum creatinine （SCr）, blood urea nitrogen （BUN）], blood lipids [triglyceride （TG）, total cholesterol （TC）, low-density lipoprotein C （LDL-C）, high-density lipoprotein C （HDL-C）], plasma total protein （TP）, hemoglobin （Hb）, serum interleukin-6 （IL-6）, and tumor necrosis factor-α （TNF-α） before and after the treatment. Results： After two courses of treatment, the levels of SCr, BUN, TG, TC, LDL-C, serum IL-6 and TNF-α decreased significantly, meanwhile HDL-C increased in the treatment group （P〈0.05 or P〈0.01）. In contrast, no obvious changes of the above mentioned items occurred in the control group. In both groups, the levels of TP and Hb were significantly elevated （P〈0.05 or P〈0.01）, but the changes were more obvious in the treatment group （P〈0.01）. Conclusion： Trilogy Detoxicating Therapy played a therapeutic role on patients with CRF possibly through lowering the levels of blood lipids, serum IL-6 and TNF- α.展开更多
