Chinese Traditional and Herbal Drugs 2013;44(24):3476-3481
Objective: To study the effects of various compatible herbs and pH value conditions on the change rule of anthraquinones in Rhei Radix et Rhizoma (RRR). Methods: The pH value of the extracted solution from seven compatible herbs[vinegar Kansui Radix (vKR), Moutan Cortex (MC), Scutellariae Radix (SR), Coptidis Rhizoma (CR), Aconiti Lateralis Radix Praeparata (ALRP), Aurantii Fructus Immaturus (AFI), and Magnoliae Officinalis Cortex (MOC)] were determined, then RRR was added into hydrochloric acid solution with the same pH value as the above solutions and boiled, in which the contents of anthraquinones were determined by UV-Vis and HPLC. The contents of anthraquinones were compared with those in the decoction of compatible herbs and single RRR. Results: The results of UV-Vis showed that total anthraquinones got the lowest amount when RRR and CR were boiled together while the highest appeared when RRR and SR were boiled together; the contents of total anthraquinones were increased when the pH value was increased. The results of HPLC showed that the five anthraquinones got the lowest dissolving-out quantity when RRR and CR were boiled together while the highest appeared when RRR and ALRP were boiled together. Under the conditions of different pH values, the highest dissolving-out quantity was got when the pH value reached 5.6. Conclusion: Both the compatible herbs and pH value could affect the dissolution of anthraquinones during the extraction. However, the effects of various compatible herbs and different pH value conditions adjusted by hydrochloric acid are different, and the pH value conditions have greater effects.

PurposeTo explore the correlation between apparent diffusion coefficient (ADC) value on MR diffusion-weighted imaging (DWI) and prognostic factors in breast invasive ductal carcinomas.Materials and Methods 103 patients with pathology-proven invasive breast ductal carcinomas underwent DWI MR scan using b=1000 s/mm2. The minimum ADC values of the lesions were determined. Histopathological specimens were analyzed for tumor size, lymph node metastasis, pathological grade (traditional prognostic factors) and the expression of prognostic factors including Ki-67, ToPo-IIα, P53 and CyclinD1. The correlations between ADC values and these prognostic factors were evaluated.Results In 103 breast invasive ductal carcinomas, there was no significant relationship between tumor size, lymph node metastasis, pathological grade and mean ADC values (P>0.05). The correlations between mean ADC values and the biological prognostic factors were not significant (P>0.05). However, positive correlations were observed between pathological grade and the expression of Ki-67 as well as ToPo-IIα(P<0.05).Conclusion ADC values cannot serve as a prognostic factor for invasive ductal breast carcinomas. However, the expression of Ki-67 and ToPo-IIα in breast invasive ductal carcinomas may be important in evaluating prognosis of the tumor and guiding clinical therapy.
