小鼠急性高位脊髓损伤对心电图的影响

目的探讨小白鼠急性高位脊髓损伤对心电图的影响。方法在小白鼠背位颈部切开,找出第4或第5颈椎,用5号针插入锥间达脊髓并横断,然后用心电图机描记高位脊髓损伤后的心电图变化。结果小鼠在高位脊髓损伤后的心电图变化规律为心率加快,P-R间期缩短,QRS波时间缩短,P波电压升高,R波电压降低和Q波电压升高(P<0.05)。结论小鼠高位脊髓损伤对心电图有一定的影响,可为小鼠高位脊髓损伤后的血流动力学改变的判断提供参考,可作为研究高位脊髓损伤后的因血流动力学变化所引起的一系列病理生理学改变提供参考指标。     

髋前外侧关节囊与髂股韧带的应用解剖及临床意义

BACKGROUND: To repair and reconstruct the joint capsule and surrounding ligaments is one of effective methods against displacement and dislocation after total hip arthroplasty. In recent years, anterolateral total hip arthroplasty has been widely used, but little is reported on the anatomic features of the anterolateral hip joint capsule and iliofemoral ligament. OBJECTIVE: To investigate the anatomic features of the anterolateral hip joint capsule and iliofemoral ligaments, thereby providing anatomic evidence for selecting and optimizing the approach for total hip arthroplasty and for clinical practice. METHODS: Thirty adult cadaver hips fixed with formalin were used for this study. The anterolateral hip joint capsule and the iliofemoral ligaments were dissected and anterolateral hip joint capsules were divided into three sections and nine parts. The average thickness of each part and the average height and width of each section were measured. The anterolateral hip joint capsule was observed by its beginning and ending, course, branch and histological features. RESULTS AND CONCLUSION: The anterolateral hip joint capsule was tightly connected with the iliofemoral ligaments to form a complex. The thickness of the capsule was varied. The thinnest parts of the complex were BI and BII. In addition, the average height and width of each section were different. The joint capsule originating from the anterior inferior iliac spine and acetabulum was divided into three branches and fixed on the intertrochanteric line. Understanding of the anterolateral hip joint capsule and iliofemoral ligaments may make for the approach selection, design and optimization of total hip arthroplasty.      

桂西地区骨关节结核患者T细胞亚群及红细胞表面免疫分子表达的研究

目的：了解骨关节结核与肺结核患者外周血 T 淋巴细胞亚群和红细胞 CD35、CD59的变化及其意义。方法收集2013年10月至2015年4月收治的60例骨关节结核患者,60例肺结核患者,选择同期健康体检者90人作为对照组。采用流式细胞仪抗体双标法检测外周静脉血 T 淋巴细胞亚群（CD3＋、CD4＋、CD8＋和 CD4＋／CD8＋）和红细胞 CD35、CD59的表达。结果与对照组比较,骨关节结核组和肺结核组 CD3＋、CD4＋和 CD4＋／CD8＋显著降低（P＜0．05）,CD8＋明显增高（P ＜0．05）;红细胞CD35、CD59表达显著降低（P ＜0．05）。骨关节结核组与肺结核患组 CD35与 CD3＋、CD4＋呈正相关（P ＜0．05）,而与 CD8＋、CD4＋／CD8＋无明显相关性（P＞0．05）。结论骨关节结核与肺结核患者 T 细胞免疫和红细胞免疫与常人比较均存在显著差异,但其是原因还是结果尚需进一步研究。     

白细胞介素12基因多态性与广西壮族人群骨关节结核易感性的关系

BACKGROUND: Interleukin-12 (IL-12) may function as an immune regulator in the pathogenesis of osteoarticular tuberculosis. OBJECTIVE: To explore the association of single-nucleotide polymorphisms in IL-12A rs568408 G/A and IL-12B rs3212227 A/C with susceptibility to osteoarticular tuberculosis and serum interleukin-12 levels in Guangxi Zhuang population. METHODS: The single-nucleotide polymorphisms in IL-12A rs568408 G/A and IL-12B rs3212227 A/C polymorphisms were detected by polymerase chain reaction-single base extension technique and direct DNA sequencing in 150 patients with osteoarticular tuberculosis (disease group) and 165 healthy individuals (control group) in Guangxi Zhuang population. The genotype and allele frequencies of IL-12 and the relationship of genotypes to the susceptibility to osteoarticular tuberculosis were analyzed. In addition, the association of genotypes of single-nucleotide polymorphisms in IL-12A rs568408 G/A and IL-12B rs3212227 A/C with serum IL-12 levels were analyzed. RESULTS AND CONCLUSION: There was no significant difference in the genotype and allele frequencies of IL-12A rs568408 G/A and IL-12B rs3212227 A/C between the disease group and the control group (P > 0.05). Moreover, there was no difference in four haplotypes of IL-12 gene between the disease group and the control group (P > 0.05). Serum IL-12 levels in subjects with osteoarticular tuberculosis carrying the variant rs568408 GA/AA genotypes and wild-type rs568408 GG genotypes were similar (P > 0.05). Similarly, there was no significant difference in serum IL-12 levels between subjects with osteoarticular tuberculosis carrying the variant rs3212227 AC/CC genotypes and wild-type rs3212227 AA genotypes (P > 0.05). These findings suggest that the single-nucleotide polymorphisms in IL-12A rs568408 G/A and IL-12B rs3212227 A/C polymorphisms are not associated with susceptibility to osteoarticular tuberculosis in Guangxi Zhuang population. 中国组织工程研究杂志出版内容重点：组织构建;骨细胞;软骨细胞;细胞培养;成纤维细胞;血管内皮细胞;骨质疏松;组织工程
