This study is to compare the therapeutic effect of posterior lumbar interbody fusion (PLIF) and transforaminal lumbar interbody fusion (TLIF) with pedicle screw fixation on treatment in adult degenerative spondylolisthesis. A retrospective analysis of 187 patients to compare the complications and associated predictive factors of the two techniques of one(More)
Total hip resurfacing arthroplasty (THRA) is being performed with increasing frequency for osteonecrosis of femoral head (ONFH). To evaluate femoral bone remodeling in ONFH after THRA and determine the impact of stem-neck angle (SNA) of inserted femoral component on bone remodeling, we monitored the changes in BMD in proximal femur in 23 patients with ONFH(More)
BACKGROUND With osteoporosis emerged as one of the most important health issues, more and more investigations are focusing on osteoporotic fracture healing. However, there are few studies on the changes of microstructure and mineralized tissue of newly formed callus. OBJECTIVE We established an osteoporotic fracture rat model to evaluate the changes of(More)
The aim of this study was to prospectively evaluate the efficacy and tolerability of hyaluronic acid (HA) and meloxicam for the treatment of knee pain due to Kashin–Beck disease (KBD). A total of 162 patients with KBD-based knee pain were randomly assigned to treatment with a 3-week course of HA (n = 80) and a 12-week course of meloxicam (n = 82). Clinical(More)
OBJECTIVE To investigate the effect of Kashin-Beck disease (KBD)-affected feed and T-2 toxin on the bone development of Wistar rats. METHODS Seventy-eight ablactation Wistal rats (50% male and 50% female) weighing approximately 65 g were obtained from Sichuan Medical Center (Chengdu, China), and were randomly assigned to three groups (Groups A, B and C).(More)
OBJECTIVE To investigate Caspase-3 expression and its role in neuronal apoptosis. METHODS The T13-L2 spinal cord of rats was injured by traction after the amplitude of P1-N1 wave, monitored by a cortical somatosensory evoked potential (CSEP) monitor, decreased to seventy percent of that before operation. Then rats were killed in 6 h, 1 d, 4 d, 7 d, 14 d(More)
This study was designed to evaluate the midterm (> or = 5 years) clinical and radiographic outcomes of the cementless total hip arthroplasty in 64 Chinese patients (72 hips), which revealed that the mean Harris hip score increased from an average of 44.0 points before operation to 92.4 points at the last follow-up. Excellent results were achieved in 60 hips(More)
OBJECTIVE To study the expression of interleukin-1 receptor in normal mice sciatic nerves and in transected sciatic nerves treated with or without extrinsic interleukin-1 locally at different periods. METHODS Seventy-two KM mice were equally divided into two groups. All the left sciatic nerves were transected. The stumps in experimental group were soaked(More)
OBJECTIVE To assess the effect of perioperative administration of a selective cyclooxygenase 2 inhibitor (celecoxib) on pain management and recovery of function after total knee arthroplasty (TKA). METHODS Randomized, controlled trial conducted from January 2005 through February 2006, 60 patients underwent TKA for osteoarthritis or rheumatoid arthritis(More)
OBJECTIVE To investigate the relationships between --1997G/T polymorphisms in collagen I alpha 1 gene (COL I A1) upstream regulatory region and bone mineral density(BMD) in postmenopausal women. METHODS There were 318 voluntary subjects in Chengdu city enrolled (212 osteoporotic postmenopausal women and 106 normal control subjects) and their BMD were(More)
