Management with the insufficient proximal landing zone for endovascular repair in aortic dissection.
Sufficient length of the proximal landing zone (PLZ) is the key for a successful thoracic endovascular aortic repair (TEVAR) of an aortic lesion. The aim of this research was to investigate the safety, feasibility, efficacy, and problems of endovascular repair for aortic dissection with insufficient PLZ. ⋯ The procedure for extending an insufficient PLZ for endovascular repair for aortic arch pathology is feasible and relatively safe. The applicability of TEVAR in such aortic disorders may be expanded.

Rs548234 polymorphism at PRDM1-ATG5 region susceptible to rheumatoid arthritis in Caucasians is not associated with rheumatoid arthritis in Chinese Han population.
A previous study has shown that rs548234 polymorphism at PRDM1-ATG5 region is associated with rheumatoid arthritis (RA) in Caucasian populations. The aim of this study was to investigate the effect of rs548234 polymorphism at PRDM1-ATG5 region on susceptibility to RA in Chinese Han population. ⋯ Our results showed no involvement of rs548234 at PRDM1-ATG5 region in the susceptibility or clinical relevance of RA in Chinese Han population.

Silencing of MGMT with small interference RNA reversed resistance in human BCUN-resistant glioma cell lines.
Our previous study had cloned two glioma cell lines SWOZ1 and SWOZ2 isolated from parental glioma cell line SWO38. The 1,3-bis(2-chloroethyl)-1-nitrosourea (BCNU) resistance of SWOZ1 was higher than that of SWOZ2. Since O6-methylguanine-DNA methyltransferase (MGMT) was thought to be closely related to BCNU resistance in glioma, this study aimed to explore the function of MGMT in glioma resistant to BCNU. ⋯ Silencing MGMT with specific small interferencing RNA can reverse the BCNU resistant phenotype in these glioma cell lines. MGMT may play an important role both in intrinsic and acquired BCNU-resistance in glioma.

Role of plasma C-reactive protein and white blood cell count in predicting in-hospital clinical events of acute type A aortic dissection.
A few recent studies have reported that inflammation is associated with the prognosis of acute aortic dissection (AD). There is, however, no systemic investigation regarding the role of plasma C-reactive protein (CRP) and white blood cell (WBC) levels in predicting in-hospital clinical events of acute type A AD. ⋯ The results suggested that CRP and WBC were preferred markers for predicting the clinical events in patients with acute type A AD, especially death during hospitalization. Therefore, further study enrolling larger cohort, prospective study would be warranted.

Magnetic resonance imaging analysis of surgical trans-sacral axial L5/S1 interbody fusion.
Trans-sacral axial L5/S1 interbody fusion (AxiaLIF), a novel surgical procedure, recently adopted in clinical practice, has excellent clinical outcomes. However, there is inadequate data on the feasibility of the approach in all adult patients and the optimal surgical approach is currently unclear; therefore, further studies are required. In order to enhance the surgical approach for AxiaLIF, prospective anatomical imaging optimization is necessary. The objective of this study was to investigate the ability of magnetic resonance imaging (MRI) to achieve an optimal procedural setting. ⋯ The AxiaLIF procedure is a safe technique for insertion of fusion implants in all subjects. Line AC is a favorable reference line for surgical approach and safe for all subjects, while line BC is not suitable for all subjects.
