Objective To observe the effects of pulsed electromagnetic field (PEMFs) or/and exercise on the area bone mineral density (aBMD) and volume bone mineral density (vBMD) of rats with osteoporosis induced by tretinoin gastric perfusion.Methods 100 female SD rats were randomly divided into 5 groups with 20 rats in each group: PEMFs group, exercise group, PEMFs plus exercise group, osteoporosis group and healthy control group. Except for the healthy control group, the osteoporosis models of other 4 groups were built by tretinoin gastric perfusion. After the building of models, each group was intervened with different treatment. In the 4th, 6th and 8th week after treatment, relevant Results of aBMD and vBMD were tested.Results Compared with the osteoporosis group, the BMD of the rats of PEMFs group, exercise group, PEMFs plus exercise group significantly increased significantly ( P<0.05) in the 6th week, 4th week and 4th week after treatment respectively. In the 6th and 8th week, there was no significant differences among the PEMFs plus exercise group, the exercise group and the PEMFs group ( P>0.05).Conclusion PEMFs can increase the BMD of the rats with osteoporosis as well as exercise. PEMFs takes effect slower than exercise.
4.Study on the risk factors for hip fracture in elderly people in Ningbo
Chinese Journal of Geriatrics 2014;33(12):1324-1326
Objective To investigate the risk factors for hip fracture in elderly people in Ningbo,in order to provide the basis for prevention and treatment of hip fracture.Methods A case-control study were conducted in study on 450 cases of hip fracture patients aged over 60 years in Ningbo and 450 subjects of control as 1 ∶ 1 matched case control study.A univariate analysis of hip fracture was performed by x2 test.Risk factors for hip fracture were analyzed by logistic regression.Results Poor self-care ability (OR=5.05),light manual labor occupation (OR=4.10),history of cerebrovascular events (OR=2.59),smoking (OR=2.14) were the risk factors for hip fracture in elderly men,while poor self-care ability (OR=11.36),light manual labor occupation (OR=2.41),osteoporosis (OR=3.19),early menopause (OR=6.89),low body mass index (OR=5.05) were the risk factors for hip fracture in elderly women.The protective factors for hip fracture was milk uptake (OR=0.29) Conclusions Early interventions for hip fracture risk factors,and prevention and treatment of osteoporosis can help reduce the occurrence of hip fracture.

Objective To assess the effect of continuous renal-replacement therapy (CRRT) dose on the outcome of acute renal failure (ARF) patients with meta-analysis of randomized controlled trials (RCTs). Methods Studies were identified by systematic search of peer-reviewed publications in Medline, EMBASE and Cochrane library database through June 2010. All the RCTs that compared the incidence of clinical outcome such as mortality, need for chronic dialysis between standard and low dose CRRT were eligible. The pooled relative risk (RR) for clinical outcome was compiled using a random-effects model. Heterogeneity was evaluated by means of subgroup and sensitivity analysis. Results Six eligible studies were identified. By meta-analysis, standard dose CRRT was associated with non-significant 13% mortality risk reduction (RR 0.87, 95%CI 0.70-1.07, P=0.19)and 13% composite outcome risk reduction of chronic dialysis dependence and mortality (RR 0.87, 95%CI 0.69-1.09, P=0.21), but the trend toward increased chronic dialysis dependence risk among survivors (RR 1.43, 95%CI 0.94-2.18, P=0.09). The overall test for heterogeneity among cohort studies was significant (P=0.001, I2=76.2%). The risk of mortality was modality was significantly lower in some studies of which delivered dose was moer than 35 ml·kg-1·min-1,modality was continuous venous-venous hemofiltration (CVVH) and major cause was non-sepsis treated with standard dose CRRT. Conclusions Standard dose CRRT in patients with ARF does not improve survival, renal recovery and composite outcome, but decreases mortality in important subgroups including those with higher delivered dose, CVVH and non-sepsis.

Objective To discuss perioperative features, operative approach and surgical effects of spinal tuberculosis in older patients. Methods Retrospective analysis was conducted to analyze the clinical data of 45 patients with spinal tuberculosis ranging in age from 61 to 78 years (average, 67 years). The lesion was located in thoracic vertebrae in 9 patients, thoracolumbar vertebrae in 14, lumbar in 16, and lumbosacral in 6. Preoperative Frankel grades were B in 7 cases, C in 21, D in 11 and E in 6. Among them, 21 had cardio-cerebrovascular disease, 10 had diabetes mellitus. With preoperative medicine and chemotherapy for 2-3 weeks, all patients were treated surgically. The surgical procedures included: 1) Posterior focus debridement, bone grafting and one-stage posterior transpedicular screw system fixation in thoracic vertebrae (T2-T7). 2) Anterior debridement, bone grafting and one-stage posterior transpedicular instrumental fixation in lumbosacral vertebrae (L5-S1). 3) Anterior focus elimination, bone grafting and one-stage anterior plate fixation in the other vertebrae. Results Forty-five patients were followed up for 24 to 40 months, with the average of 28.5 months. No severe complication occurred during and after operation. Forty-four cases had recovered and 1 recurred. Spinal fusion occurred 12-18 months after operation. Frankel neurological grades improved significantly. Conclusion With the effective management of comorbidities in perioperative period,the elderly could tolerate surgical treatment. The appropriate approaches, thorough debridement and reasonable bone grafting with internal fixation are key to therapeutic success.
