AIM OF THE STUDY Polygonum cillinerve (Nakai) Ohwi is commonly used in China for over 2000 years. Previous research has shown that the crude polysaccharides extracted from Polygonum cillinerve (Nakai) Ohwi (PCCP) have the scavenging free radicals and anti-tumor activities in vitro. In present study, PCCP were further approached the perspective of their(More)
A simple, sensitive and specific flow-injection spectrofluorimetric method has been developed for the determination of folic acid in pharmaceuticals. The method is based on use of a lead dioxide solid-phase reactor for on-line oxidation of folic acid into a strongly fluorescent compound with a maximum excitation wavelength of 281 nm and an emission(More)
BACKGROUND Hypoxic preconditioning can protect hepatocytes against hypoxic injury, but its mechanism has not been elucidated. The aim of this study was to profile gene expression patterns involved in hypoxic preconditioning and probable mechanism at the level of gene expression. METHODS Hepatocytes were divided into 2 groups: control group and hypoxic(More)
OBJECTIVE To develop an HPLC method for the simultaneous separation and determination of oxalic acid (OA), tartaric acid(TA), malic acid(MA), vitamin C (VC), lactic acid (LA), acetic acid (AA) citric acid (CA) and succinic acid (SA) in Fructus mume. METHOD Analytical column was Zorbax Eclipse XDB C18. Mobile phase was 0.5% (NH4) H2PO4 aqueous solution and(More)
Avascular necrosis of the femoral head is one of the most frequently reported complications in patients with systemic lupus erythematosus (SLE) and often requires total hip arthroplasty (THA). Our objective was to analyze the perioperative management, technical problems, clinical outcomes, and complications associated with THA in patients with SLE. A total(More)
A study about the ultrasonic extraction, antioxidant capacity and identification of phenolics from Semen Astragali Complanati was undertaken. The optimised extraction condition with an orthogonal experiment design of L9(3(4)) was 50°C, 30min and 15:1 (methanol solution:sample, mL:g). An extraction yield of 40.12±1.10mg gallic acid/g dry seed and the(More)
Composite porous scaffolds have attracted extensive attention in the biomedical material field. The aim of this research was to prepare a novel tri-component composite porous scaffold and to evaluate its relevant properties. The porous scaffold was composed of chitosan (CS), silk fibroin (SF), and nanohydroxyapatite particles (nHA), which we named CS/SF/nHA(More)
Human adipose-derived stem cells (hADSC) are capable of differentiating into an osteogenic lineage. It is believed that microRNAs (miRNAs) play important roles in regulating this osteogenic differentiation of human adipose-derived cells, although its molecular mechanism remains unclear. We investigated the miRNA expression profile during osteogenic(More)
BACKGROUND The effect of body mass index (BMI) on the outcome of total hip arthroplasty (THA) remains controversial. The purpose of this study was to examine whether revision rate and postoperative outcomes following THA were influenced by BMI. MATERIALS AND METHODS We retrospectively evaluated 714 patients (751 hips) who underwent primary THA in our(More)
The present study was undertaken to evaluate the potential cardioprotective effects of apricot kernel oil (AO) on the myocardial ischemia-reperfusion (IR) of rat model in vivo. The rats were divided into five groups: sham-operated, IR, low dose AO-treated IR (LD-AO+IR), medium dose AO-treated IR (MD-AO+IR) and high dose AO-treated IR (HD-AO+IR). All rats(More)
