The aim of the study was to evaluate the pharmacokinetics (PK) of lansoprazole (LPZ) and its main metabolites 5'-hydroxy lansoprazole (HLPZ) and lansoprazole sulphone (LPZS) after single intravenous (i.v.) doses of LPZ in healthy Chinese subjects, and the relationship between the cytochrome P450 (CYP) 2C19 phenotypes and the plasma concentrations of LPZS at(More)
In a recent study, we demonstrated that vagal stimulation increases the survival of rats with myocardial infarction by inhibiting lethal arrhythmia through regulation of connexin43 (Cx43). However, the precise mechanisms for this effect remain to be elucidated. To investigate these mechanisms and the signal transduction for gap junction regulation, we(More)
A sensitive and specific LC-MS/MS method for the simultaneous quantification of niacin (NA) and its three main metabolites nicotinamide (NAM), nicotinuric acid (NUA) and N-methyl-2-pyridone-5-carboxamide (2-Pyr) in human plasma has been developed and validated. Plasma samples (200 μL) were prepared by deproteinization with acetonitrile (500 μL), then the(More)
170 SD rats were randomly divided to five groups. Rats in model group, no-acupuncture group, and acupuncture group were subjected to MCAO surgery. Acupuncture group received 3 consecutive acupuncture treatments at a parameter that deep in 2 mm towards apex nasi and thrust/lifted at 3 times per second for 1 minute, while model group and no-acupuncture group(More)
We examined the kinetics of IL-8 production and CagA status in AGS infected with Helicobacter pylori, 26695 (Western CagA-type), HPK5 (Eastern CagA-type) and isogenic cagA-disrupted mutants, exposed to different pH (pH 6 and pH 3). IL-8 was produced in the early and late phases after infection in CagA-dependent and -independent manners, respectively,(More)
The purpose of this study was to elucidate the pharmacokinetics of terazosin enantiomers in healthy Chinese male subjects. After a single oral dose of 2-mg terazosin, the plasma concentrations of terazosin enantiomers were measured over the course of 48 h in 12 healthy subjects. The plasma concentrations of (+)-(R)-terazosin at all time points were higher(More)
OBJECTIVES To evaluate the effects and safeness of combined hysterolaparoscopy on evaluation the causes of infertility. METHODS This retrospective study was conducted at the Department of Gynecology (The Third Affiliated Hospital of Sun Yat-Sen University, Guangzhou, Guangdong, China) from January 2011 to April 2014. Patients aged 21-43 years with(More)
The individual difference and non-repeatability in acupuncture have not only restricted the development of acupuncture, but have also affected the specificity of acupoints. The present study used instruments to control needle depth, lifting and thrusting frequency, and the duration of acupuncture. Effects of the quantified acupuncture were observed at(More)
The aim of the study was to evaluate and compare the pharmacokinetics of lansoprazole (LPZ) and its main metabolites, 5′-hydroxy lansoprazole (HLPZ) and lansoprazole sulfone (LPZS), after single and multiple intravenous (i.v.) doses of LPZ in healthy Chinese subjects. Twelve subjects (six males and six females) were given a single dose of LPZ by i.v.(More)
Irinotecan is a well-known chemotherapy drug for the treatment of various cancers. However, delayed-onset diarrhea is a common adverse reaction, limiting the application of the drug. The study presented was designed to evaluate the preventive effects of Shengjiang Xiexin decoction (SXD) on irinotecan-induced diarrhea and to explore the possible mechanisms(More)
