ABSTRACT

Trabecular microstructure is an important factor in determining bone strength and physiological function. Normal X-ray and computed tomography (CT) cannot accurately reflect the microstructure of trabecular bone. High-resolution peripheral quantitative computed tomography (HR-pQCT) is a new imaging technique in recent years. It can qualitatively and quantitatively measure the three-dimensional microstructure and volume bone mineral density of trabecular bone . It has high precision and relative low dose of radiation. This new imaging tool is helpful for us to understand the trabecular microstructure more deeply. The finite element analysis of HR-pQCT data can be used to predict the bone strength accurately. We can assess the risk of osteoporosis and fracture with three-dimensional reconstructed images and trabecular microstructure parameters. In this review, we summarize the technical flow, data parameters and clinical application of HR-pQCT in order to provide some reference for the popularization and extensive application of HR-pQCT.

ABSTRACT

Objective To evaluate the efficacy and safety of continuous femoral nerve block (CFNB) versus patient controlled analgesia (PCA) for analgesia in primary total knee arthroplasty (TKA) through a Meta-analysis.Methods All randomized controlled trials (RCTs) which compared about the efficacy and safety of CFNB versus PCA for analgesia in primary TKA,were searched from Cochrane Library,Embase,PubMed,CBM,VIP,Wang Fang database and CNKI.At the same time,conference papers were identified manually.A quality assessment of the included literature was evaluated by Cochrane system evaluation manually.Revman 5.3 software was used for the Meta-analysis to compare visual analogue scale (VAS),hospital for special surgery knee score (HSS),western Ontario and McMaster university of orthopedic index (WOMAC),patient satisfactory degree,and incidences of complications (nausea,vomit,dizziness,somnolence,itch of skin,etc).Results Twenty-four RCTs involving 1896 patients were identified including CFNB (946 cases) and PCA (950 cases) application of TKA.The pooled results illustrated that CFNB could reduce VAS in rest (MD =-1.28,95% CI-1.56,-1.00,P < 0.05) and VAS in movement (MD =-0.98,95% CI-1.38,-0.58,P < 0.05),increase HSS (MD =2.13,95% CI 0.12,4.14,P <0.05),reduce WOMAC(MD =-0.97,95% CI-1.83,-0.11,P < 0.05),increase patient satisfactory degree (RR =1.27,95 % CI 1.10,1.46,P < 0.05) and at the same time reduce the incidences of nausea,vomit,dizziness,somnolence and itch of skin (RR =0.32,95%CI0.24,0.43,P<0.05).Conclusion Compared with PCA,CFNB analgesia can reduce VAS,WOMAC score,improve the postoperative HSS and patient satisfaction degree,and decrease the risk of complications.

ABSTRACT

Osteoporosis is a systemic metabolic osteopathy characterized by low bone mineral density, leading to an increased risk of bone fractures. The study on the treatment of osteoporosis is mostly a research hotspot, and traditional Chinese medicine in treatment of this disease has its distinctive ascendancy. A large quantity of research indicates that the effect of Longspur epimeium (LE) for treatment of osteoporosis is definite. In this article, the authors summarized the drug components, the results of experimental research and clinical trial of LE for treatment of osteoporosis in recent years.
