Cephalometric and three-dimensional assessment of the posterior airway space and imaging software reliability analysis before and after orthognathic surgery

PurposeThis study aimed to compare the reliability of three different imaging software programs for measuring the PAS and concurrently to investigate the morphological changes in oropharyngeal structures in mandibular prognathic patients before and after orthognathic surgery by using 2D and 3D analyzing technique.Material and methodsThe study consists of 11 randomly chosen patients (8 females and 3 males) who underwent maxillomandibular treatment for correction of Class III anteroposterior mandibular prognathism at the University Hospital in Zurich. A set of standardized LCR and CBCT-scans were obtained from each subject preoperatively (T0), 3 months after surgery (T1) and 3 months to 2 years postoperatively (T2). Morphological changes in the posterior airway space (PAS) were evaluated longitudinally by two different observers with three different imaging software programs (OsiriX^® 64-bit, Switzerland; Mimics^®, Belgium; BrainLab^®, Germany) and manually by analyzing cephalometric X-rays.ResultsA significant increase in the upper airway dimensions before and after surgery occurred in all measured cases. All other cephalometric distances showed no statistically significant alterations. Measuring the volume of the PAS showed no significant changes in all cases. All three software programs showed similar outputs in both cephalometric analysis and 3D measuring technique.ConclusionA 3D design of the posterior airway seems to be far more reliable and precise phrasing of a statement of postoperative gradients than conventional radiography and is additionally higher compared to the corresponding manual method. In case of Class III mandibular prognathism treatment with bilateral split osteotomy of the mandible and simultaneous maxillary advancement, the negative effects of PAS volume decrease may be reduced and might prevent a developing OSAS.

膨大素对川麦冬生长发育及其产量和质量的影响

目的研究膨大素对川麦冬生长发育及其产量、质量的影响。方法在收获期随机采样测定川麦冬的生物学性状及产量,用SPSS软件分析川麦冬生物学性状与产量的相关性规律;用UV法测定川麦冬中的总皂苷,考察膨大素的施用量和施用方式对其质量的影响。结果川麦冬的植株生物学性状(除块根直径、株高外)对产量均有显著影响,影响程度为单株块根重>块根数>分蘖数>块根长>百粒重>冠幅。膨大素能促进川麦冬植株地上部分的生长,明显增加块根数、单株块根重,显著提高川麦冬的产量;除低剂量外,膨大素降低了川麦冬总皂苷的含量,且随着剂量的增加,作用越强。结论膨大素能促进川麦冬的生长发育,显著提高川麦冬的产量,且与多效唑分段合用时效果更佳。不同剂量膨大素对川麦冬总皂苷含量的影响差异较大,低剂量有利于川麦冬总皂苷的积累。     

Rapid Detection of Rare Deleterious Variants by Next Generation Sequencing with Optional Microarray SNP Genotype Data

Autozygosity mapping is a powerful technique for the identification of rare, autosomal recessive, disease‐causing genes. The ease with which this category of disease gene can be identified has greatly increased through the availability of genome‐wide SNP genotyping microarrays and subsequently of exome sequencing. Although these methods have simplified the generation of experimental data, its analysis, particularly when disparate data types must be integrated, remains time consuming. Moreover, the huge volume of sequence variant data generated from next generation sequencing experiments opens up the possibility of using these data instead of microarray genotype data to identify disease loci. To allow these two types of data to be used in an integrated fashion, we have developed AgileVCFMapper, a program that performs both the mapping of disease loci by SNP genotyping and the analysis of potentially deleterious variants using exome sequence variant data, in a single step. This method does not require microarray SNP genotype data, although analysis with a combination of microarray and exome genotype data enables more precise delineation of disease loci, due to superior marker density and distribution.     

二维斑点追踪超声心动图左房软件及左室软件测量左房机械形变功能的一致性分析

目的 评估TomTec工作站左房及左室两种斑点追踪超声心动图软件测量左房整体纵向应变及应变率的一致性分析。方法 收集64个受检者的临床资料及超声心动图图像,两名受规范化培训医师分别应用2D-STE左房及左室软件获得左房整体纵向收缩期应变(Sct)、通道期应变(Scd)、左房储存期应变(Sr=Sct+Scd)及收缩期应变率(SRct)、通道期应变率(SRcd)、储存期应变率(SRr)。通过比较测量者内和测量者间获得的左房应变及应变率测值以评估两种软件测量的一致性有无差异。结果 （1）两种软件测量者内和测量者间的测值存在差异,仅左室软件测量者间SRcd差异有统计学意义（P=0.01）;（2）Bland-Altman一致性检验提示两种软件有较好的一致性,但左房软件测值较左室软件偏倚小,一致性区间较左室软件范围小;（3）测量者信度分析,左房软件测值较左室软件一致性好。结论 二维斑点追踪超声心动图左房专用软件较左室软件测值偏倚小,一致性范围稳定,测量者的重测信度优秀,值得在左房功能分析中推广应用。
