UNLABELLED To study the cost of osteoporotic fracture in China, we performed a prospective study and compared the costs of the disease in referral patients with fractures in three of the most common sites. Our results indicated that the economic burden of osteoporotic fracture to both Chinese patients and the nation is heavy. INTRODUCTION This paper aims(More)
OBJECTIVE To explore the effects of AST (astragalosides) on cultured rat islet yield, purity, and function after cryopreservation in rats. METHODS Pancreatic islets were isolated from 30 Sprague-Dawley rats using the standard technique of collagenase P digestion and discontinuous Ficoll gradient purification. After thaw, the islets were randomly divided(More)
OBJECTIVE We sought to explore the adjunctive effects of Cordyceps sinensis (CS) in clinical renal transplantation. MATERIALS AND METHODS Patients (n = 202) were divided randomly by lottery into a treatment (n = 93) and a control group (n = 109). Patients in the treatment group were treated with CS 1.0 g 3 times a day in addition to the immunosuppressive(More)
Two physiologically active diterpenoids were isolated from the flower of Chinese azalea (Ericaceae Rhododendron molle G. Don). One of them is a new compound, named rhodomollein-III; its structure has been established as 1 through IR, MS, 1HNMR, 13C NMR, 1H-1H COSY, 1H-1H NOESY, 13C-1H COSY and long-range 13C-1HCOSY. The other one is the known(More)
Criterion for contacting is critically important for the Generalized Interpolation Material Point(GIMP) method. We present an improved criterion by adding a switching function. With the method dynamical response of high melting explosive(HMX) with cavities under shock is investigated. The physical model used in the present work is an elastic-to-plastic and(More)
Objective: To establish ion chromatography method to determine thiocyanate within urine of workers who were exposed to cyanide. Methods: After the workers work, used 50 ml centrifuge tube to collect the urine of workers about 20 ml.The urine were tested by centrifugation, dilution and filtration by C(18) column, thiocyanate was separated by AS(16) and(More)
AIM Gene expression profiles for intervertebral disc (IVD) cells treated with different osmolarities were compared to identify key genes associated with intervertebral disc diseases. MATERIALS AND METHODS Microarray data was downloaded from Gene Expression Omnibus (GEO) database and pre-processed using package of R. Gene co-expression was determined with(More)
beta-Keto ester(5) was obtained from vanilin through etherification, oxidation and condensation with acetoacetic ester, (5) on oxidative coupling reaction by NaOEt/I2 produced dimer (6) in high yield. Acid catalyzed cyclodehydration of (6) gave the furan derivative(7), and by a series of selective hydrogenation nordihydroguaiaretic acid, furoguaiacin(More)
The collapse of cavities under shock is a key problem in various fields ranging from erosion of material, ignition of explosive, to sonoluminescence, etc. We study such processes using the material-point-method developed recently in the field of solid physics. The main points of the research include the relations between symmetry of collapsing and the(More)
