BACKGROUND: Tuberculosis clearance, bone graft, internal fixation with or without plate for patients with spinal tuberculosis always lead to C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) changes, which are associated with bone graft union time to certain degree.OBJECTIVE: To analyze the correlation between CRP, ESR and bone graft union time in patients with spinal tuberculosis.METHODS: A total of 60 patients with spinal tuberculosis underwent tuberculose focus clearance, autologous iliac bone grafting, and internal fixation without or with plate, including 38 undergoing fixation and 22 not undergoing fixation. They were divided into mild elevation, moderate elevation, high elevation, and extremely high elevation groups according to CRP and ESR. Correlation between CRP, ESR and bone graft union time was analyzed.RESULTS AND CONCLUSION: (1) CRP: there were 18 cases of mild elevation, 21 of moderate elevation, 13 of high elevation and 8 of extremely high elevation. There were significant differences in bone union time among groups (P=0.003). Spearman correlation analysis showed a correlation coefficient r=0.420, P=0.001, indicating positive correlation between CPR and bone union time. (2) ESR: there were 16 cases of mild elevation, 20 of moderate elevation, 13 of high elevation and 11 of extremely high elevation. There were significant differences in bone union time among groups (P=0.003). Spearman correlation analysis showed a correlation coefficient r=0.414, P=0.001, indicating positive correlation between ESR and bone union time. (3) Bone union was rapider in fixation group compared with non-fixation group, indicating that immediate, strong fixation can benefit bone union.

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.

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 al ele 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 al ele 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.

Objective To investigate the frequencies of genotype and allele distribution of IL-12A gene single nucleo?tide polymorphisms (SNP) rs568408 and IL-12B gene SNP rs3212227 in Zhuang populations in Guangxi, and to compare the distribution of IL-12A and IL-12B polymorphisms among different races. Methods The IL-12A SNP rs568408 and IL-12B SNP rs3212227 were detected by SNaPshot SNP genotyping technique in 165 Zhuang people in Guangxi, frequen?cies of genotype and allele of IL-12A gene rs568408 and IL-12B rs3212227 polymorphisms were analyzed in Zhuang popu?lations compared with the other four populations(HapMap-HCB, HapMap-JPT, HapMap-YRI, HapMap-TSI)from Hap?Map database. Results There were polimorphisms of IL-12A and IL-12B gene in Zhuang populations in Guangxi. The fre?quencies of allele and genotype distribution of IL-12A gene rs568408 polymorphisms were not significantly differenct com?pared with HapMap-HCB, HapMap-JPT and HapMap-TSI(P>0.05), but were significantly different compared with Hap?Map-YRI(P<0.01);The frequencies of allele and genotype distribution of IL-12B rs3212227 polymorphisms were not sig?nificantly differenct compared with HapMap-HCB and HapMap-JPT(P>0.05), but were significantly different compared with HapMap-YRI and HapMap-TSI(P<0.01). Conclusion There are significant differences in the frequencies of allele and genotype distribution of IL-12A gene rs568408 and IL-12B gene rs3212227 between Zhuang populations and other eth?nic populations, and this variation might contribute to a variety of clinical manifestation and morbidity of some IL-12 related diseases.
