MethodsHPLC-DAD method was used to determine the constituents in preparations. Diamonsil? C_(18) (200mm X 4.6 mm, 5 μm) was used as analytical column, and acetonitrile/KH_2PO_4 was used as mobilephase with gradient elu-tion. The column temperature was at 24 ℃. The HPLC profile of chemicalconstituents of control sample and preparations were analyzed using similarity software. Results Thefingerprints of different preparations from different companies were slightly different because ofthe different preparing procedures. Mean while, the fingerprints of different batches of the samepreparation from the same company were similar to each other and the technology of each preparationwas stable. Conclusion This method is accurate, reproducible , simple, and can be used as ananalytical method for the routine quality control of Ginkgo biloba preparations.展开更多

A total of 6 patients （1 female and 5 males） with histologically confirmed liver cancer were included in this retrospective observational clinical trial. We administered Chinese medicine （Gan Decoction, mixed with a variety of effective herbal components） to help them to recover from poor condition. In the meantime, conventional treatment of surgical resection and artery catheterization chemotherapy was applied in cases compared. In 3 cases of CTM combined treatment, the tumor marker level decreased. Residual intrahepatic metastatic sites reduced according to ultrasonography/CT imaging, and the patients felt free from the complaint of abdominal discomfort. The quality of life has been improved, we managed to have prolonged the PFS （Progression-Free-Survival） and TTP （Time-to-Progression） from the onset to date. While in 3 cases with conventional treatment only of surgical resection and artery catheterization chemotherapy, we were not able to decrease the level of tumor marker, metastatic lesions increased according to ultrasonography/CT imaging, and the patient＇s condition worsen more. We failed in having prolonged the PFS and TTP in the compared cases of conventional treatment only. The retrospective clinical study showed no OS （overall survival） benefit for liver cancer patients treated with Gan Decoction, while the QOL （quality of life） evaluation seemed to predict survival better. Chinese herbs might be an additional choice with its better benefits and tolerability in the treatment of primary liver cancer.展开更多

To achieve this aim, the phospholipid fatty acid （PLFA） profiles, microbial biomass C （Cmic）, and dehydrogenase （DHA） and urease activities （URA） were monitored at the beginning （To）, 3 h （T1） and 97 d （Tf, i.e., the end） of incubation after FOMWW addition. After the FOMWW addition, an increase in the ratio of fungal to bacterial PLFAs was observed in ADS soil. Moreover, a relative increase of monounsaturated fatty acids （MUFAs） with respect to saturated fatty acids （SATFA） was found in the ADS soil. An increase of the Gram-positive to Gram-negative ratio was observed in this soil at the end of the incubation. While DHA and Cmic increased in the ADS soil after FOMWW addition, URA showed a decrease. Fungi and Gram-positive bacterial biomass experienced an increase after addition of a high dose of FOMWW in laboratory conditions.展开更多
