BACKGROUND Dislocation is the second most common complication of hip replacement surgery, and impact of the prosthesis is believed to be the fundamental reason. The present study employed Solidworks 2003 and MSC-Nastran software to analyze the three dimensional variables in order to investigate how to prevent dislocation following hip replacement surgery.(More)
OBJECTIVE To develop the techniques of total hip arthroplasty(THA) for Crowe type IV developmental dysplasia of the hip (DDH) with S-ROM prosthesis,and to assess its clinical results. METHODS From October 2000 to October 2011,30 patients (36 hips) with Crowe type IV DDH underwent THA,including 6 patients with bilateral hip involved and 24 patients with(More)
OBJECTIVE The aim of this study was to investigate the effects of andrographolide on matrix metalloproteinases (MMP) 1, 3, and 13 and inducible nitric oxide synthase (iNOS) in human articular chondrocytes from osteoarthritic cartilage. METHODS Passaged chondrocytes were pretreated with or without andrographolide for 2 h, followed by coincubation with(More)
Thirteen species and one variety of the genus Lactarius (Russulaceae, Russulales) have been published from China. Since the original descriptions and illustrations are often poor, it is difficult to understand the concepts of these taxa. Therefore, the type specimens of all these taxa were traced, reviewed and (or) re-examined by employing modern taxonomic(More)
This paper provides an overview and identification key of the Australasian species of Lactarius subg. Gerardii. A molecular phylogeny based on the nuc DNA markers ITS, LSU and rpb2, combined with detailed morphological observations resulted in the delimitation of 12 strongly supported and morphologically recognizable species. Five new agaricoid species are(More)
BACKGROUND Periprosthetic femoral fractures following total hip arthroplasty are getting more prevalent. The aim of this study was to evaluate the clinical results of combined use of uncemented extensively porous coated femoral components with onlay cortical strut allografts in revision of Vancouver type B2 and B3 periprosthetic femoral fractures. METHODS(More)
OBJECTIVE To evaluate the outcome of total hip arthroplasty (THA) with cementless cups and femoral head autografts for patients with hip dysplasia and osteoarthritis. METHODS Between 1995 and 2002, we implanted 23 cementless cups and femoral head autografts in 20 patients with hip dysplasia and osteoarthritis. In this study, a retrospective study was made(More)
Overexpression of matrix metalloproteinases (MMPs), inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) have long been suggested to play crucial roles in the progression of osteoarthritis. Studies have showed that selective MMPs, iNOS and COX-2 inhibitors possess great potential as chondroprotective agents for osteoarthritis. Therefore,(More)
BACKGROUND Ceramic bearing surfaces have been introduced to prevent osteolysis after total hip arthroplasty (THA), but little is known about the difference in clinical and radiological results between pure alumina and sandwich alumina bearings. The purpose of this study was to analyze the results obtained with third-generation alumina-on-alumina THA with(More)
This study was aimed to detect the ratio of CD34+ cells in bone marrow mononuclear cells (BMMNCs) and the expression rate of G(M)-CSFR on CD34+ cells in bone marrow of the patients with aplastic anemia (AA) and myelodysplastic syndrome (MDS). The ratio of CD34+ cells in BMMNCs and the expression rate of G(M)-CSFR on cells of 27 AA patients, 45 MDS patients(More)
