三维及多平面重建CT技术在鼻部整形中的应用价值分析

目的:分析在鼻部整形中三维及多平面重建CT技术的应用价值。方法:选择2018年2月~2019年7月本院收治的60例行鼻部整形的患者进行分析,所有患者均开展三维及多平面重建CT技术检测,结合检查结果,开展相应的隆鼻手术。分析术后不良反应、患者满意度。术后6个月,在CT测量下,检测前后鼻部解剖数据。结果:在鼻部整形中,三维及多平面重建CT技术的应用,可以准确了解鼻部结构,如观察侧鼻骨、鼻部皮肤、鼻根等情况。术后评价,患者对鼻部整形满意度较高,术后6个月,患者对鼻部整形满意度较高,术后与术后6个月患者鼻部满意度相比,无统计学意义,P>0.05。术后60例患者没有出现出血、切口感染等反应,同时也没有出现肋软骨外漏与倾斜等现象。经随访术后6个月发现1例患者的鼻背软骨出现轻度弯曲,但无明显表现,没有做特殊处理;其余患者,鼻部外形均表现为鼻尖挺拔、鼻背曲线流畅。结论:在鼻部整形中,应用三维及多平面重建CT技术,可以辅助提高隆鼻手术准确度,并在CT技术的引导下,准确植入自体肋软骨,可以为手术成功奠定基础,促使鼻唇与周围器官形态的协调性,进一步提高患者满意度。

Multifaceted effects of aluminium in neurodegenerative diseases: A review

Aluminium (Al) is the most common metal and widely distributed in our environment. Al was first isolated as an element in 1827, and its use began only after 1886. Al is widely used for industrial applications and consumer products. Apart from these it is also used in cooking utensils and in pharmacological agents, including antacids and antiperspirants from which the element usually enters into the human body. Evidence for the neurotoxicity of Al is described in various studies, but still the exact mechanism of Al toxicity is not known. However, the evidence suggests that the Al can potentiate oxidative stress and inflammatory events and finally leads to cell death.Al is considered as a well-established neurotoxin and have a link between the exposure and development of neurodegenerative diseases, including Amyotrophic Lateral Sclerosis (ALS), Alzheimer’s disease (AD), dementia, Gulf war syndrome and Parkinsonism. Here, we review the detailed possible pathogenesis of Al neurotoxicity. This review summarizes Al induced events likewise oxidative stress, cell mediated toxicity, apoptosis, inflammatory events in the brain, glutamate toxicity, effects on calcium homeostasis, gene expression and Al induced Neurofibrillary tangle (NFT) formation. Apart from these we also discussed animal models that are commonly used for Al induced neurotoxicity and neurodegeneration studies. These models help to find out a better way to treat and prevent the progression in Al induced neurodegenerative diseases.     

Accuracy of two midsagittal planes in three-dimensional analysis and their measurement in patients with skeletal mandibular deviation: a comparative study

Our aim was to evaluate the accuracy of two midsagittal planes (MSP) to provide a better reference plane for studying the 3-dimensional structural symmetry in patients with skeletal mandibular deviation. Thirty adult patients with facial asymmetry were admitted to the Department of Orthodontics, Hospital of Stomatology, between January 2015 and 2017. The DICOM data were collected and reconstructed using ProPlan CMF^® 2.0 (Materialise). Two sets of reference planes were set up. In the orbital margin plane group, the plane crossing the nasion (N) point and perpendicular to the frontozygomatic (FZ) suture line was used as the MSP. In the skull base plane group, the MSP was established using the sella turcica (S), N, and basion (Ba). The distances from the craniofacial skeletal and soft tissue midline landmarks to the two MSP were separately measured, and the significance of differences between measurements corresponding to two reference planes were assessed using the paired t test. Except for the posterior nasal spine (PNS)-MSP, the distances from other soft and hard tissue landmarks to the MSP in the orbital margin plane group were significantly shorter than those in the skull base plane group. In the 3-dimensional measurement analysis, the skeletal and soft tissue anatomical midline landmarks were closer to the MSP in the orbital margin plane group. The MSP crossing point N, perpendicular to the FZ suture line, was more accurate and suitable.
