人体赤足形态特征接触面积与身高体质量相关性统计分析

背景:当前法医人类学、人体工程学及足迹学研究均发现足部各信息(如足长、足宽等)与身高、体质量呈现出显著相关性,但国内外文献对有关赤足形态特征接触面积与人体身高、体质量的量化研究尚不完善。目的:分析人体赤足形态特征接触面积与身高、体质量之间相关性,创新法医人类学、人体工程学等相关学科理论体系,为利用赤足足迹进行人身个体识别提供参考。方法:采用足迹学传统平面足迹油墨捺印方法进行样本收集,再利用MATLAB数字软件对足迹对象进行图像处理。测试对象为随机抽取身高分布在165-190 cm之间健康的青壮年男性100名,记录其身高、体质量,获取正常行走步态下的赤足形态特征接触面积并进行统计分析。试验的实施符合《赫尔辛基宣言》和中国刑事警察学院对人体研究的相关伦理要求。结果与结论:在健康青壮年男性正常弓类型(排除中断弓和膨胀弓两种弓区类型)条件下:①人体赤足形态特征接触面积与身高、体质量之间均呈显著正相关(P<0.01),其与人体身高之间关系可被应用于法医人类学、人体工程学、足迹学的身高分析;②身高相较于体质量而言,对人体赤足形态特征接触面积的影响更加显著,更具有直接相关性。     

Pedicled Islanded Nasolabial Flap Tunneled Under Mandible for Tongue Reconstruction

BackgroundNasolabial flap is reliable flap in the reconstruction of oral defects over a period of time. Still there is scanty literature available of using this flap for reconstruction of isolated defects of tongue. We carried out this study in our patients to assess the role of pedicled nasolabial flap in reconstruction of isolated tongue defects.MethodsIn total, 11 patients with T1 and T2 tongue cancer were selected for the study. The functional improvement in the form of speech and swallowing was evaluated postoperatively.ResultsThe flap was successfully taken in all patients except for marginal or tip loss. This is a locally available flap with minimal operating time and does not require microvascular skills. The results of speech and swallowing after reconstruction were comparable.ConclusionNasolabial flap is an excellent locally available flap for the reconstruction of the anterior two-thirds of the tongue and with very minor, if any postoperative cosmetic defect.     

双极电凝联合1%聚桂醇泡沫硬化剂治疗16例舌微囊型淋巴管畸形疗效观察

目的: 评价双极电凝联合1%聚桂醇泡沫硬化剂治疗舌微囊型淋巴管畸形的临床疗效及安全性。方法: 回顾分析2017年4月—2020年4月佛山市第一人民医院口腔科收治的16例舌微囊型淋巴管畸形患者的临床资料,男7例,女9例,年龄15个月~21岁,平均（8.32±1.21）岁,对治疗效果和并发症进行分析。结果: 16例患者全部随访6~12个月。疗效评价为Ⅳ级11 例（68.75%）,Ⅲ级3例（18.75%）,Ⅱ级2例（12.5%）,Ⅰ级0例,有效率87.5%。1例出现舌黏膜、舌肌坏死。结论: 双极电凝联合1%聚桂醇泡沫硬化剂治疗舌微囊型淋巴管畸形是一种微创、安全、有效的治疗方法。     

Reliability of Lateral Cephalometric Radiographs in the Assessment of the Upper Airway in Children: A Retrospective study

ObjectivesTo test the reliability of Lateral cephalometric radiographs (LCRs) for use in the assessment of the upper airway, hyoid bone, soft palate, and tongue.Materials and MethodsThe records of 57 healthy Chinese children from a nonhospital population (mean age = 12.6 years, SD = 0.5, 28 males and 29 females) who received two consecutive LCRs in the natural head posture were retrospectively analyzed. Fifteen linear, angular, and area measurements were used to describe the airway, hyoid bone, soft palate, and tongue. The reliability between the two LCRs was assessed with the intraclass correlation coefficient (ICC) and F-test. Errors were estimated with the Dahlberg and Bland-Altman method, and intra- and inter-assessor agreements were determined.ResultsMeasurements of upper airway and hyoid bone had excellent method reliability, intra-assessor reliability, and inter-assessor reliability (ICC > 0.8). However, the method reliability and the inter-assessor reliability for soft palate and tongue was less favorable (ICC from 0.60 to 0.96). Soft palate area and thickness were the most critical parameters. Intra-assessor reliability was greater than both method reliability and inter-assessor reliability (which were similar).ConclusionsThe measurement of upper airway morphology, defined as the intramural space, and of the hyoid bone position were highly reliable on LCRs of children. However, the limited reliability in the assessment of tongue and soft palate area may compromise the diagnostic application of LCRs to these structures.

An ultrasound examination of tongue movement during swallowing

Six female adults were studied during the production of four single swallows each, using real-time ultrasound. A pellet was affixed to the tongue at the junction between the (calculated) anterior third and posterior two-thirds of the tongue surface. Direction, rate, and extent of pellet movement were measured and used to create stages of tongue blade movement during swallowing. Pellet movement was then compared to the three stages of hyoid movement (ascent, steady, descent). Anterior-posterior and superior-inferior components of pellet movement were examined and discussed.     

iASPP在舌鳞癌组织中的表达及意义

目的：探讨iASPP在舌鳞癌组织中的表达及意义。方法临床收集16例舌鳞癌癌旁组织、71例舌鳞癌组织,通过免疫组化检测 iASPP的表达情况,并对其表达水平进行统计学分析。结果在舌癌旁组织中, iASPP少量位于棘层细胞胞浆中,呈淡黄色颗粒。在舌鳞癌组织中iASPP主要分布于上皮全层,其表达显著高于舌癌旁组织(P<0．05)。不同分化程度及是否淋巴结转移舌鳞癌患者中,iASPP的平均表达水平有显著性差异(P<0．05)。低分化者表达水平最高,高分化者表达水平最低,有淋巴结转移者表达水平高于无淋巴结转移者( P<0．05)。不同临床分期iASPP的表达无显著差异。结论 iASPP表达的改变可能与舌鳞癌的发生发展有关。     

四种检验方法在细菌性阴道炎诊断的临床价值

目的探讨4种检验方法对细菌性阴道炎的临床诊断作用与应用价值。方法选取该院2012年7月至2014年5月80例疑似细菌性阴道炎患者,分别使用胺试验、线索细胞检查、乳酸杆菌检查、细菌性阴道炎(BV)快速检测法进行检测,并对4种方法的检测结果作比较分析。结果乳酸杆菌检测阳性率为80.0%,线索细胞检查为78.75%,传统检查法(胺试验、pH值)为62.50%与61.25%、BV快速检测法为77.50%。BV快速检测法检出阳性率显著高于传统检测法,差异有统计学意义(P0.05);传统检测法检测结果与其他3种比较,诊断结果最差。结论 BV快速检测法对细菌性阴道炎的检测速度较快且检出率较高,具有临床价值。
