OBJECTIVE To study the technical conditions of the extraction and purification of the active composition from Polygonum orientale and Crataegus pinnatifida Bge. in Hongye Xingtong soft capsules with the macroporous resin. METHOD The orientm, isorientm and hyperoside were used as index to screen the five kinds of resins. And the technical conditions of the(More)
The pathological lesions induced by multiwalled carbon nanotubes (MWCNTs) in bronchi and alveoli of mice were studied by intratracheal instillation and inhalation. In instillation groups, the dose was 0.05 mg MWCNTs/mouse. Similar size clumps of MWCNTs were distributed in bronchi and alveoli. The clumps led to inflammation to the lining wall of bronchi and(More)
Peripheral arterial disease is a major complication of diabetes. The ability to promote therapeutic angiogenesis may be limited in diabetes. Type 2 diabetes was induced by high-fat feeding C57BL/6 mice (n = 60). Normal chow-fed mice (n = 20) had no diabetes. Mice underwent unilateral femoral artery ligation and excision. A plasmid DNA encoded an engineered(More)
Since finding the minimum connected dominating set (MCDS) in an arbitrary graph is a NP-hard problem, many algorithms have been proposed to construct an approximation of the MCDS for efficient routing in wireless sensor networks (WSNs). To address the weaknesses of these existing algorithms, we propose a novel distributed MCDS approximation algorithm,(More)
Diabetic retinopathy is characterized by pathological retinal neovascularization. Accumulating evidence has indicated that high levels of circulating endothelial progenitor cells (EPCs) are an important risk factor for neovascularization. Paradoxically, the reduction and dysfunction of circulating EPCs has been extensively reported in diabetic patients. We(More)
BACKGROUND Intravenous leiomyomatosis (IVL) is a rare tumor that is histologically benign but biologically malignant. Less than 200 cases of IVL have been reported, most of them were individual reports. METHODS Six patients with IVL involving the inferior vena cava were analyzed. RESULTS Three patients received one-stage operations and two received(More)
Hydrogen-rich saline has been reported to prevent neointimal hyperplasia induced by carotid balloon injury. The purpose of the present study was to further investigate the molecular mechanisms underlying this phenomenon. Daily injection of a hydrogen-rich saline solution (HRSS) in rats was employed to study the effect(More)
Long-term clinical studies of drug-eluting stents (DES) have reported high incidence of late thrombosis. Given the growing concern over the clinical application of this technology, we have developed a stent coated with bi-layered PLGA nanoparticles (BL-PLGA NPs) containing VEGF plasmid in the outer layer and paclitaxel (PTX) in the inner core (VEGF/PTX(More)
An efficient and sensitive method for simultaneous determination of 102 pesticide residues in teas has been established and validated. The multi-residue analysis of the pesticides in teas involved extraction with acetone-ethyl acetate-hexane, clean-up using gel permeation chromatography (GPC) and solid-phase extraction (SPE), and subsequent identification(More)
