强直性脊柱炎合并骨质疏松的临床研究

Objective To investigate the incidence of osteoporosis (OP) in patients with ankylosing spondylitis and the relationship between OP and the clinical data. Methods Serum levels of bone alkaline phosphatase (BALP) and tartrate resistant acid phosphatase 5b (TRACP5b) were detected by enzyme linked immunosorbent assay ( ELISA ) in 60 cases with ankylosing spondylitis, and it was compared with normal controls. Bone mineral density (BMD) was measured through dual-energy X-ray absorptiometry ( DXA), including lumbar ( L2 - L4), bilateral femoral neck and greater trochanter. Some clinical data was collected and analyzed at the same time. Results The incidence of OP in AS patients was 35%, and the incidence of OP in the femoral proximal end was higher than that in lumbar. Compared with normal controls[ ( 1.06 ±0. 18 )U/L ], the levels of serum TRACP5b in AS[ (1.31 ± 0. 82 )U/L] patients was significantly higher ( P <0. 05 ). The levels of serum BLAP in OP combined AS group[ ( 21.65 ± 5.41 ) U/L]were significantly lower than non-OP group[ (32. 37 ± 16. 5 ) U/L] ( P <0. 05 ). The disease duration was negatively correlated with the BMD of femoral neck ( P < 0. 01 ). Conclusions There was higher incidence of OP in AS patients, which were related with the abnormality of bone metabolism and the disease duration.Multiple factors participated in the regulation of bone metabolism of AS.

降钙素对大白兔糖尿病骨质疏松模型假体骨密度及生物力学的影响

Objective To investigate the influence of calcitonin on bone mineral density and biomechanics around the artificial pros-thesis in ovariectomized diabetic rabbit model. Methods Fourteen femina New Zealand white rabbits at the age of 5 months old were select-ed, which weight 2.24 -2.65kg, averaging 2.26kg. First, the model of rabbit with diabetic osteoporosis was successfully established by the compound method of ovariectomy plus streptozotocin. Osteotomy in the middle part of femur was performed in both groups, fixation of artifi-cial prosthesis was done with 3.0 kirschner wire. After that, Rabbit models with diabetic osteoporosis were randomly divided into experimen-tal group and control group. Rabbits in the experimental group were treated with calcitonin 6U intramuscular injection once every other day. In control group, intramuscular injection of normal saline solution 1.5ml once every three days. Rabbit models of two groups were sacrificed in the 24th week. The BMD of the region of interest (ROI) around the prosthesis were detected before experiment and 8, 16 and 24 weeks after injection. After rabbits were killed, experimental femurs in both groups were complete removal and soft tissues were rejected. Determi-nation of the pull-out and torsion bone biomechanics experiments of prosthesis was done in both groups respectively. Results The BMD of ROI in the experimental group before operation was (0.1863±0.004)g/cm2 and (0.1753±0.005)g/cm2 in 24 weeks after operation, in control group before operation was (0.1865±0.002)g/cm2 and (0.1638±0.005)g/cm2 in 24 weeks after operation. There were significant difference between the two groups(P < 0.05). Biomechanical show that the pull-out strength in the experimental group was (312.68±8.73 )N/cm2 and (205.43±12.45 ) N/cm2 in control group. There were significant difference between the two groups(P < 0.05). The tor-sion strength in experimental group was (80.47±2.51) N/cm2 and (38.52±0.64) N/cm2 in control group. There were significant differ-ence between the two groups(P < 0.05). Conclusion Salmon calcitonin can reduce the bone turnover rate around prosthesis and decrease bone absorption in the rabbit of diabetic osteoporosis models, accelerate the bone formation around prosthesis, and increase the BMD. It can ameliorate the quality of bone around prosthesis, improve its biomechanics property, and increase the holding power between prosthesis and body mass. It is of clinical significance for the prevention and treatment of aseptic loosening artificial prosthesis.
