丹红注射液联合玻璃酸钠关节腔内注射对胫骨骨折患者血清骨性标志物水平的影响

目的:研究丹红注射液联合玻璃酸钠关节腔内注射对胫骨骨折术后血清骨性标志物水平的影响。方法:研究对象选取我院2015年5月到2016年8月间收治的胫骨骨折患者110例,所有患者均行切开复位内固定手术治疗。采用随机数字法将其分为对照组和观察组,每组各55例。对照组患者玻璃酸钠关节腔内注射治疗,观察组患者配合丹红注射液。比较两组患者的治疗疗效、治疗前后的视觉模拟评分法(VAS评分)、血清骨钙素(bone Glaprotein,BGP)、I型前胶原羧基端肽(carboxyterminal propeptide of type I procollagen,PICP)水平的变化。结果:治疗后1、3、7天患处疼痛VAS评分均明显低于对照组(P0.05),治疗后1、2、4周观察组患者关节活动度评分均明显高于对照组(P0.05),治疗后观察组患者血清BGP、PICP水平均明显高于对照组(P0.05)。结论:丹红注射液联合玻璃酸钠关节腔内注射能够促进胫骨骨折术后骨折愈合,提高临床疗效。可能与其有效提高患者血清BGP、PICP水平有关。     

Cloning of the bone Gla protein gene from the teleost fish Sparus aurata. Evidence for overall conservation in gene organization and bone-specific expression from fish to man

Bone Gla protein (BGP, Osteocalcin) is a bone-specific vitamin K-dependent protein which has been intensively studied in mammals. Although BGP is the most abundant non-collagenous protein of bone, its mode of action at the molecular level remains unclear. From an evolutionary point of view, the appearance of BGP seems to parallel the appearance of hydroxyapatite-containing bone structures since it has never been found in elasmobranchs, whose skeleton is composed of calcified cartilage. Accordingly, recent work indicates that, in mammalian bone, BGP is required for adequate maturation of the hydroxyapatite crystal. Taken together, these data suggest that teleost fishes, presumably the first vertebrates to develop a BGP-containing skeleton, may be a useful model to further investigate BGP function. In addition, fish offer several advantages over mammalian models, due to a large progeny, external embryonic development and transparency of larvae. In the present work, the BGP cDNA and gene were cloned from a teleost fish, Sparus aurata, and its tissue distribution, pattern of developmental expression and evolutionary pathways analyzed. The molecular organization of the Sparus BGP (spBGP) gene is similar to mammalian BGP genes, and its expression throughout development follows the onset of calcification. The spBGP gene encodes a pre-propeptide of 97 amino acid residues, expressed only in bone and showing extensive homology to its mammalian homologs. Phylogenetic analysis of the available BGP sequences supports the hypothesis that all BGPs have a single origin and share a common ancestor with a related vitamin K-dependent protein (Matrix Gla protein).
