目的:利用石英晶体微平衡-分散(QCM-D)技术研究白蛋白在高度亲水和高度疏水表面的吸附情况。方法:利用等离子聚合技术在8片圆形石英传感器上形成六甲基二硅氧烷薄膜聚合体薄膜,将4片上述试样采用低温氧等离子体轰击80 s,这两种表面分别代表高度疏水及高度亲水表面。将处理后的两种传感器装入QCM-D检测仪,将400 mg/L的牛血白蛋白溶液引入传感检测室,观察共振频率和离散因子随时间的变化,计算出蛋白的吸附量。结果:白蛋白在两种表面的吸附主要在早期10 s中完成,此后吸附变慢,在30 min左右达到吸附-离散平衡,30 min时白蛋白在高度疏水表面的平均吸附量为294.6 ng/cm2,而在高度亲水表面平均吸附量为235.1 g/cm2,两者有显著性差异。结论:QCM-D可以用来精确测定蛋白质在石英传感器表面的吸附,高度疏水性表面对白蛋白有较高的吸附能力。

目的:利用低温等离子体轰击法建立高分子聚合体表面润湿性研究模型。方法:使用氧低温等离子体轰击六甲基二硅氧烷薄膜聚合体表面,测定表面接触角,建立轰击时间-表面接触角曲线,建立线型回归方程。观察在不同介质中保存时材料表面接触角的变化情况。结果:经过氧等离子体轰击后,六甲基二硅氧烷薄膜聚合体表面接触角明显下降,与处理时间呈现负相关性。在空气中保存时,表面接触角随时间逐渐上升,0度接触角表面24 h后上升为20°左右,而在双蒸水中保存的表面接触角基本保持不变。结论:氧等离子体轰击法能可控性地改变六甲基二硅氧烷薄膜聚合体表面润湿性,处理后的表面在水中接触角保持稳定,该方法可以用来建立表面润湿性研究模型。

Risk factors for fracture in adult kidney transplant recipients

World Journal of Transplantation 2016年第2期6卷 370-379页

AIM: To determine the general and transplant-specific risk factors for fractures in kidney transplant ***: We conducted a cohort study of all adults who received a kidney-only transplant(n = 2723) in Ontario, Canada between 2002 and 2009. We used multivariable Cox proportional hazards regression to determine general and transplant-specific risk factors for major fractures(proximal humerus, forearm, hip, and clinical vertebral). The final model was established using the backward elimination strategy, selecting risk factors with a P-value ≤ 0.2 and forcing recipient age and sex into the model. We also assessed risk factors for other fracture locations(excluding major fractures, and fractures involving the skull, hands or feet). RESULTS: There were 132 major fractures in the follow-up(8.1 fractures per 1000 person-years). General risk factors associated with a greater risk of major fracture were older recipient age [adjusted hazard ratio(a HR) per 5-year increase 1.11, 95%CI: 1.03-1.19] and female sex(a HR = 1.81, 95%CI: 1.28-2.57). Transplant-specific risk factors associated with a greater risk of fracture included older donor age(5-year increase)(a HR = 1.09, 95%CI: 1.02-1.17) and end-stage renal disease(ESRD) caused by diabetes(a HR = 1.72, 95%CI: 1.09-2.72) or cystic kidney disease(a HR = 1.73, 95%CI: 1.08-2.78)(compared to glomerulonephritis as the reference cause). Risk factors across the two fracture locations were not consistent(major fracture locations vs other). Specifically, general risk factors associated with an increased risk of other fractures were diabetes and a fall with hospitalization prior to transplantation, while length of time on dialysis, and renal vascular disease and other causes of ESRD were the transplant-specific risk factors associated with a greater risk of other ***: Both general and transplant-specific risk factors were associated with a higher risk of fractures in kidney transplant recipients.

Retrieving dental instruments through endoscopy: A literature review

引用

World Journal of Stomatology 2015年第4期4卷 137-140页

作者： Rhonan Ferreira Silva Ademir Franco Fernando Fortes Picoli Mayara Barbosa Viandelli Mundim Livia Graziele Rodrigues Depart-ment of Stomatological Sciences Forensic Odontology Federal University of Goiás Depart-ment of Forensic Odontology and Anthropology Scientific Police of Goiás department of Stomatology Pontifícia Univer-sidade Católica do Paraná

Clinical accidents involving dental instruments and materials inside the oral cavity are reported in the medical literature. Specifically, ingestion and aspiration of foreign bodies have greater prevalence in the routine of medicine and dentistry. Despite being less harmful than aspirations, the accidental ingestion of dental instruments does not always culminate in favorable prognoses. Mostly, complex conditions require medical intervention through endoscopy or surgical approaches. The present research aims to review the literature pointing out the specialties of dentistry most involved with accidental ingestion of dental instruments, highlighting the important role of endoscopy for accurately locating and retrieving foreign bodies. Prosthodontics, operative dentistry, orthodontics, and maxillofacial surgery arose as the specialties in which these accidents are more prevalent. Based on that, general dentists and specialists must be aware for the essential care to avoid such clinical accidents, as well as to know the available tools, such as endoscopy, to overcome these situations in the routine of dentistry.
