全髋关节置换术中假体周围骨折的研究进展 总被引:2,自引:2,他引:0
全髋关节置换术是一个较为成熟的手术,术中假体周围骨折是其并发症之一,假体周围骨折分为髋臼假体周围骨折和股骨假体周围骨折,危险因素包括微创技术的使用、压配式非骨水泥假体柄的使用、髋关节翻修术和骨质疏松等。本文就全髋关节置换术中假体周围骨折的分型及治疗进展进行综述。 相似文献

目的比较5种布鲁氏菌核酸实时荧光PCR检测试剂盒的一致性和检出能力,为临床实验室选择检测方法和布鲁氏菌的诊断提供参考依据。方法选用经病原学检测确定为布鲁氏菌阳性的血液样本38份,健康人的血液样本24份,潘氏变形杆菌、溶藻弧菌、河弧菌、铜绿假单胞菌、肺炎克雷伯菌DNA各1份,使用5种试剂盒(编号A-E)分别进行核酸检测,比较5种试剂盒临床样本检测的一致性;选择1份阳性样本核酸用无RNA酶水梯度稀释得到5个浓度(浓度1:4453.13 fg/μL,浓度2:1113.28 fg/μL,浓度3:278.32 fg/μL,浓度4:69.58 fg/μL,浓度5:17.40 fg/μL),每个浓度使用5种试剂盒(编号A-E)分别进行3次检测,比较5种试剂盒的阳性检出率及批内重复性。结果5种试剂盒检测67份DNA样品的符合率稍有不同,试剂盒ABDE的符合率均为100%,试剂盒C的符合率为98.51%。批内重复性显示5种试剂盒在浓度1、浓度2、浓度3水平重复检测DNA的Ct值变异系数均<5%;在浓度1与浓度4梯度区间,试剂盒的阳性检出能力比较显示试剂盒A、B、D较高,为11/12,试剂盒C和E较低,为8/12。结论5种试剂盒的真实性和可靠性较好,灵敏度和符合率稍有差别,特异度均为100%;重复性较好,检测性能良好。部分试剂盒对弱阳性样本的检出能力不强,该类样本可使用多种试剂盒复核,以保障结果的准确性。 相似文献

目的探讨急性颈脊髓损伤后发生低钠血症的相关因素、发病机制、诊断及治疗。方法回顾性分析2001年4月-2007年3月收治的急性颈脊髓损伤后低钠血症患者16例的临床资料。所有患者血钠〈130mmol/L,尿钠36~79mmol/L,尿渗透压390~910mmol/L,均采用3%高渗盐水静脉滴注。结果16例患者中,1例术后3天因呼吸功能衰竭死亡,2例失访,其余13例经限水、适当补钠治疗后血钠恢复正常。结论低钠血症的发生与颈脊髓损伤的程度密切相关,限水、适当补钠是有效的治疗方法。 相似文献

目的探讨针刺联合康复训练治疗中风后遗症的临床疗效及对脑血流速度的影响,进一步指导临床。方法选取中风后遗症住院患者96例,将其随机分为治疗组和对照组,每组48例,对照组患者给予常规的内科对症治疗,治疗组患者在对照组的基础上给予针刺配合康复训练治疗,观察2组的临床疗效及神经功能缺损程度、日常生活能力、脑血流速度的影响。结果治疗组的总有效率明显优于对照组,差异显著具有统计学意义(P0.05),治疗组治疗后神经功能缺损评分(NIHSS评分)、日常生活活动量表(ADL)评分改善程度明显优于对照组(P0.05),2组患者治疗后脑血流速度均有所增快,但治疗组改善程度明显优于对照组,差异显著具有统计学意义(P0.05)。结论针刺联合康复训练治疗中风后遗症临床疗效显著,值得临床借鉴。 相似文献

BACKGROUND: Semaphorin7A (Sema7A) is a kind of cell surface protein, which can promote the fusion of osteoclasts and the migration of osteoblasts at the same time, affecting the dynamic balance of the bone. It is speculated that Sema7A siRNA may inhibit osteoblast apoptosis induced by titanium particles.OBJECTIVE: To study the effect of Sema7A on the preosteoblast activity inhibited by titanium particles.METHODS:Mouse MC3T3-E1 preosteoblasts at passages 6 and 7 were divided into four groups: in blank control group, MC3T3-E1 cells were cultured alone; in standard control group, cell were cultured with titanium particles; in experimental groups 1 and 2, the cells were cultured with titanium particles+Sema7A overexpression plasmids and titanium particles+Sema7A siRNA, respectively. Apoptotic rate of MC3T3-E1 cells was detected by flow cytometry; the mRNA expression of bone sialoprotein, osteocalcin and type I collagen was detected by Q-PCR; western blot assay was adopted to detect the protein expression of bone sialoprotein, osteocalcin and type I collagen; alizarin red calcium nodule staining was taken to detect the degree of osteoblast mineralization.RESULTS AND CONCLUSION: The expressions of bone sialoprotein, osteocalcin and type I collagen were decreased in the standard control group and experimental group 1, but these expression were significantly increased in the experimental group 2 compared with the standard control group (P < 0.05). Flow cytometry results suggested that the apoptotic rate of osteoblasts in the experimental group 1 was significantly higher than that in the other groups (P < 0.05), and the apoptotic rate in the experimental group 2 was lower than that in the standard control group (P < 0.05). Alizarin red staining showed that there were no obvious mineralized nodules in the experimental group 1, but mineralized nodules formed in the experimental group 2. In brief, the genetic interference technique that inhibits the activity of Sema7A can interfere the process of mouse MC3T3-E1 preosteoblast differentiation inhibited by titanium particles, and thus provide a feasible way for the clinical treatment of wear particles-induced osteolysis using biotechnology.
