PURPOSE: The purpose of this study is to explore the influence of segmentation of the upstream and downstream parent artery and hemodynamic boundary conditions (BCs) on the evaluated hemodynamic factors for the computational fluid dynamics (CFD) analysis of intracranial aneurysms. MATERIALS AND METHODS: Three dimensional patient-specific aneurysm models were analyzed by applying various combinations of inlet and outlet BCs. Hemodynamic factors such as velocity pattern, streamline, wall shear stress, and oscillatory shear index at the systolic time were visualized and compared among the different cases. RESULTS: Hemodynamic factors were significantly affected by the inlet BCs while there was little influence of the outlet BCs. When the inlet length was relatively short, different inlet BCs showed different hemodynamic factors and the calculated hemodynamic factors were also dependent on the inlet length. However, when the inlet length (L) was long enough (L>20D, where D is the diameter of inlet section), the hemodynamic factors became similar regardless of the inlet BCs and lengths. The error due to different inlet BCs was negligible. The effect of the outlet length on the hemodynamic factors was similar to that of the inlet length. CONCLUSION: Simulated hemodynamic factors are highly sensitive to inlet BCs and upstream parent artery segmentation. The results of this work can provide an insight into how to build models and to apply BCs for more accurate estimation of hemodynamic factors from CFD simulations of intracranial aneurysms.

Objective This study is aimed to evaluate the association between the ABCG2 gene rs2231142 variant and gout using meta-analysis. Methods Related studies were identified by searching extensively in Chinese and foreign language databases such as Pubmed, EMBASE, Cochrane Library, CBMdisc databases and so on. The quality of included studies was assessed by using the Newcastle-Ottawa Scale (NOS). The odds ratio (OR) was calculated using a random-effects or fixed-effects model. A Q statistic was used to evaluate the heterogeneity, and Eggerˊs test and funnel plot were used to assess publication bias. Sub-group analyses on ethnicities and sex were also performed. Results A total of 10 studies, including 3 478 gout patients and 10,089 controls from 6 countries or regions, were included and identified for the current metaan-alysis. It was found that the A allele or AA genotype of the ABCG2 rs2231142 polymorphism had an increased risk for gout in the general population [A allele: OR=2.03, 95%CI (1.77, 2.34), P<0.01 and AA genotype: OR=3.01, 95%CI (2.34, 3.88), P<0.01, respectively]. Similar results were found in sub-group analyses of different gender and races. Conclusion Existing evidence indicate that rs2231142 polymorphism (the A allele and AA genotype) is associated with increased risk of gout.
