ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

OBJECTIVE:To study the anti-oxidative effects of spirulina kinase (SPK) in vitro. METHODS:The methods of phenanthroine-Fe2+ oxidation method,DPPH and auto-oxidation of pyrogallol were used to measure the effects of different concen-trations of SPK on scavenging hydroxyl (OH-) free radical,DPPH free radical and superoxide anion (O2-) free radical;IC50 of SPK was calculated. Prussian blue reaction was used to determine total reducing ability(by absorbance)of different concentrations of SPK to Fe3+. Vitamin C(VC)was used as positive control in above trials. RESULTS:SPK could eliminate the OH-free radical, DPPH free radical and O2- free radical in concentration-dependant manner,and the maximum elimination rate of SPK to OH- free radical and DPPH free radical were 86.82% and 78.98%(IC50 were 54.31,0.636 g/L),which were higher than VC (64.77%, 73.49%). The maximum elimination rate of SPK to O2- free radical was 78.31%(IC50 was 3.918 g/L),which was lower than VC (94.14%). In reducing ability test,SPK improved absorbance in reducing ability test system,and maximum absorbance was simi-lar to VC in concentration-dependant manner. CONCLUSIONS:SPK has obvious anti-oxidant activities in vitro.
