Increasing evidence places Schisandrin B (Sch B) at an important position in nerve protection, indicating that Sch B might play a positive role in the therapy of neurodegenerative diseases. However, there is little information on it. Our studies showed that pretreatment with Sch B could reduce lactate dehydrogenase, malondialdehyde, and reactive oxygen(More)
OBJECTIVE To investigate the prevalence of rheumatic heart disease (RHD) among schoolchildren in Guangdong Province and Xinjiang Uygur Autonomous Region. METHODS Using a cluster sampling method, an epidemiological survey of RHD was conducted in 16 682 primary and high school students by auscultation in Guangdong Province and Xinjiang Uygur Autonomous(More)
OBJECTIVE To identify the differentially expressed proteins in the serum of patients with cervical cancer for use as the biomarkers for early diagnosis of cervical cancer. METHODS Surface-enhanced laser desorption/ionization time of flight mass spectrometry (SELDI-TOF-MS) with weak cationic chips (CM10) was used to examine the serum samples of 24 patients(More)
OBJECTIVE Chinese crude drug Mori Cortex Radicis (the root cortex of Morus species) has been used as a folk medicine to treat hypertension, diabetes, as well as in expectorant, diuretic agents. This investigation aims to study the anti-hyperlipidemia effects of Mori Cortex Radicis (MCR) extracts in hyperlipidemic rat models and the potential therapeutic(More)
OBJECTIVE To observe the effect of Schisandra chinensis lignans (SCL) on neuronal apoptosis and PI3K/AKT signaling pathway of rats in the cerebral ischemia injury model, and study its possible mechanism. METHOD Rats were orally administered SCL high, middle and low dose groups (100, 50, 25 mg x kg(-1)) for 14 days. The cerebral ischemia injury model was(More)
Four new sesqui-lignans, (7R, 7'R, 7″S, 8S, 8'S, 8″S)-4',5″-dihydroxy-3,5,3',4″-tetramethoxy-7,9':7',9-diepoxy-4,8″-oxy-8,8'-sesquineo-lignan-7″,9″-diol (1), (7R, 7'R, 7″S, 8S, 8'S, 8″S)-4',3″-dihydroxy-3,5,3',5',4″-pentamethoxy-7,9':7',9-diepoxy-4,8″-oxy-8,8'-sesquineo-lignan-7″,9″-diol (2), (7R, 7'R, 7″S, 8S, 8'S,(More)
Two new lignans were isolated from Saururus chinensis, along with eight known compounds. Their structures were elucidated on the basis of spectroscopic and physico-chemical analyses. All the isolates were evaluated for in vitro inhibitory activity against DGAT1 and DGAT2. Among them, compounds 2, 3, 5 and 7 were found to exhibit selective inhibitory(More)
Hepatoprotective effects of Chinese herbal medicine Schisandra Chinensis (Schisandra) have been widely investigated. However, most studies were focused on its lignan extracts. We investigated the effects of Schisandra polysaccharide (SCP) in a mouse model of non-alcoholic fatty liver disease (NAFLD), and studied its effect on sterol regulatory element(More)
