The pathogenesis of glucocorticoid (GC)-induced osteonecrosis (ON) the femoral head remains unclear. Recent research has suggested that it is closely associated with injured bone microvascular endothelial cells (BMECs). However, few studies have used BMECs to perform pertaining ON head.The objective this study was investigate functional changes treated a GC and detect in related genes using microarrays.Cells were isolated an enzymatic method identified EC markers, such as von Willebrand...

Femoral neck-shaft angle (NSA) is the included by femoral neck axis (FNA) and shaft (FSA), which a critical anatomic measurement index for evaluating biomechanics of hip joint. Aiming at solving problem that physician’s manual NSA time consuming irreproducible, this paper proposes fully automatic approach on radiographs. We first present an improved deep convolutional generative adversarial network to automatically segment region interest radiographs pelvis. Then based geometrical...

The mean patient age 32.6 ± 14.3 years, follow-up duration 27.4 16.1 months. We also recoded analyzed values preoperative...

Total hip arthroplasty (THA) is a successful method to treat osteoarthritis secondary the developmental dysplasia of (DDH). As anatomic deformity acetabulum, center placing socket may lead insufficient host bone coverage, therefore, high (HHC) technique an alternative choice. Location rotation can be referenced by inter teardrop line, highest point obturator foramen, summit iliac crests, ischial tuberosities and other landmarks. The HHC supposed increase coverage without structural grafts,...

Our aim was to assess the accuracy of obtained posterior tibial slope (PTS) with a fixed angle cutting block. 247 TKAs in 213 patients were reviewed. We included 104 Legion Prosthesis, 76 U2 Knee 46 NexGen LPS-Flex and 21 Vanguard System products. Preoperative postoperative PTS measured via expanded lateral tibia radiographs. For PTS, group had significantly smaller slopes than group. However, there no significant difference between groups, among NexGen, Knee, groups. Multiple linear...

A unilateral 30-min application of anodal direct current to the promotor cortex rabbits was repeated 10 times, and cyclic AMP accumulation in response histamine investigated slices different cortical areas. Polarization with 1.0 microA decreased area contralateral polarization, by which regional dominance produced polarized cortex. In contrast, difference reversed when 10.0 or 30.0 applied. The histamine-elicited almost completely inhibited selective H2-receptor antagonist cimetidine. These...

Abstract Background Although the tip of greater trochanter is widely used in THA to adjust leg length discrepancy (LLD), its accuracy and reliability are still unknown. The aim this study was investigate measuring LLD patients with total hip arthroplasty using distance from inter-teardrop line Methods 128 who underwent our department preoperative postoperative bilateral hips anteroposterior(AP) radiographs were reviewed. between anterior superior iliac spine medial malleolus (ASIS-MM)...

Abstract Objective For total knee arthroplasty (TKA) tibial bone resection, various manufacturers provide cutting blocks with fixed angles. But the accuracy of these angles is uncertain. Our aim was to assess obtained posterior slope (PTS) a angle block. Methods 247 TKAs in 213 patients were reviewed. We included 104 Legion Prosthesis, 76 U2 Knee 46 NexGen LPS-Flex and 21 Vanguard System products. Preoperative postoperative PTS measured via expanded lateral tibia radiographs. The component...

Objective To investigate the distribution of hip rotational center on normal bilateral radiographs and to determine variation in center. Methods From June 2013 December 2013, 200 AP hips PACS China-Japan Friendship Hospital were reviewed. The height horizontal distance acetabular measured relation inferior edge teardrop evaluate difference between right left centers, range of±SD×2 which was defined as 95% variation. Intraclass correlation coefficient ( ICC) used intraobserver...

Objective: To investigate the reliability of distance between tip greater trochanter and inter-teardrop line (GT-IT) in evaluating leg length discrepancy (LLD) patients underwent total hip arthroplasty (THA). Methods: Patients who THA Xi'an Honghui Hospital from August 2015 to February 2016 were enrolled this study.The measured for bilateral hips anterior-posterior (AP) radiograph preoperatively postoperatively.Four distances measured, included: GT-IT, lesser bi-ischial (LT-BI); LT-IT...

Abstract Background : Tibial rotation in total knee arthroplasty remains controversial. The aim was to investigate which anatomical reference closer SEA 10 tibial markers Chinese adult. Methods study included 122 normal lower extremities. axes were drawn on the axial sections: transverse axis of tibia(TAT), medial edge patellar tendon (MEPT), 1⁄3 attachment (M1/3), Akagi line, Insall border tubercle(MBTT)，axis anterior tibia 1-4(ATC1-4). angles between TAT and as well other perpendicular...

Abstract Background To understand the roles of synovial tissue in rheumatoid arthritis (RA), we comprehensively investigated protein profiles tissues patients with RA and osteoarthritis (OA).
