The aim of the present study was to elucidate the differences in the plasma concentration of two enantiomers of donepezil in Chinese patients with Alzheimer's disease (AD) and investigate in vitro stereoselective metabolism and transport. Donepezil enantiomers were separated and determined by LC-MS/MS using D5-donepezil as an internal standard on a Sepax(More)
BACKGROUND Since the introduction of tyrosine kinase inhibitors (TKIs) into combination chemotherapy regimens, the majority of newly diagnosed Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ ALL) patients have achieved complete remission (CR). However, without allogeneic hematopoietic stem cell transplantation (HSCT), long-term outcomes(More)
Traditional treatment of chronic idiopathic thrombocytopenic purpura (CITP) is usually adopted as hormonal therapy. If necessary, it also can be given immunosuppressive therapy. In order to investigate the curative effect of rhIL-11 on patients with ITP, 26 patients were divided into control group and rhIL-11 group, each group with 13 patients. Control(More)
The ethanolic root extract of Codonopsis lanceolata were evaluated for anti-inflammatory activity using the carrageenan induced rat hind paw edema model and displayed a significant activity of 51.82% inhibition at 200 mg/kg at 3 h (p < 0.05). Further isolation of the extract yielded two new triterpenoid saponins, named codonolaside I (1) and codonolaside II(More)
OBJECTIVE To investigate the role of Pim-3 abnomal expression in development of acute myeloid leukemia. METHODS Semi-quantitative RT-PCR was used to detect the expression of Pim-3 in bone marrow of 47 newly diagnosed and untreated patients with acute myeloid leukemia (AML) and 18 patients with AML after treatment with chemotherapy. At the same time, the(More)
OBJECTIVE To study the flavonoids in the leaves of Apocynum ventum. METHOD Compounds were separated by repeated polyacrylamide column chromatgraphy combined with Sephadex LH-20 column chromatgraphy, their structures were confirmed by the analysis of spectral data and physicochemical properties. RESULT Six compounds were isolated from A. ventum. They(More)
OBJECTIVE To investigate the prolyl oligopeptidase inhibitory constituents from Glehnia littoralis. METHODS To determine the prolyl oligopeptidase inhibitory activity in vitro of ethanol extract of G. littoralis and its fractions with Yoshimoto's method, to separate the constituents of the active fractions by repeated silica gel column chromatogrphy.

Lipopolysaccharide-induced nitric oxide and the protease prolyl oligopeptidase (EC have been proposed as targets for the treatment of cognitive disturbances such as dementia. In this study, nine triterpenoids isolated from the roots of Sanguisorba officinalis, including arjunic acid (1), rosamultic acid (2), haptadienic acid (3),(More)
In a well-controlled multi-center randomized trial in southwestern China, 228 patients with refractory or relapsed AML were received a low-dose CAG regimen either with etoposide (E-CAG) or without etoposide (CAG). The complete remission (CR) rate, overall survival (OS) and toxicity were evaluated. Patients with E-CAG had a higher CR rate (71.1% vs. CAG(More)
