Strain-based elastography assessment of patients with De Quervain tenosynovitis: A preliminary study

Introduction

The development of the condition is occurs by repeated strain of the APL and EPB tendons as they pass under a thickened and swollen extensor retinaculum.De Quervain tenosynovitis prevalence is about 0.5% in males and 1.3% in females. In the recent years, De Quervain tenosynovitis incidence increases by virtue of modern life conditions such as excessive computer use and increased use of cellular phones.

剪切波弹性成像诊断胆道闭锁价值的Meta分析

目的对近年来公开报道的应用剪切波弹性成像诊断胆道闭锁的相关研究做一荟萃分析,初步评估剪切波弹性成像在诊断胆道闭锁中的价值。方法根据检索式对中英文数据库文献进行检索,按研究纳入排除标准筛选文献,并使用QUADAS-2量表对纳入文献的质量进行评价。提取文献数据,拟合SROC曲线。结果本荟萃分析共检索到相关文献132篇,按纳入与排除标准,最终纳入数据分析的研究共7项,结果提示剪切波弹性成像诊断胆道闭锁拟合SROC曲线下面积为0.90(95%CI:0.88~0.93),灵敏度为84%(95%CI:72%~92%),特异度为83%(95%CI:70%~91%)。结论剪切波弹性成像诊断胆道闭锁的临床应用前景可观,但目前尚缺乏前瞻性、高质量的临床诊断试验,各研究间异质性较大,其诊断价值尚有待进一步验证。儿童剪切波弹性成像检测方法目前尚没有统一标准,有待进一步探索、完善。     

超声弹性成像技术在甲状腺结节中的临床应用价值

目的探讨超声弹性成像技术在甲状腺结节诊断中的临床应用价值。方法对经手术病理证实的127例甲状腺结节患者（158个结节）的术前常规超声、超声弹性成像特征进行回顾性分析,并与病理结果进行对照。结果本组158个甲状腺结节,病理证实良性结节127个,其中弹性分级0～11级者109个（85．8％）,弹性分级Ⅲ-Ⅳ级者18个（14．2％）;31个恶性结节中有4个（12．9％）弹性分级为0～Ⅱ级,27个（87．1％）结节为Ⅲ～Ⅳ级。超声弹性成像诊断甲状腺结节良恶性的敏感性和特异性分别为87．1％和85．8％,明显高于常规超声检查的67．7％和81．1％（P〈0．05）。结论超声弹性成像技术可显著提高超声对甲状腺良恶性结节的鉴别诊断能力。

目的采用Meta分析评价经直肠剪切波弹性成像在前列腺癌诊断中的应用价值。方法检索2016年12月以前有关经直肠剪切波弹性成像诊断前列腺癌的中、英文文献,按照诊断性试验的纳入标准筛选文献,采用Meta-Disc 1.4及Stata 12.0软件对纳入的文献进行Meta分析。结果共纳入8篇文献,其中经直肠剪切波弹性成像诊断前列腺癌的研究有5篇,汇总分析后,其诊断前列腺癌的合并敏感度(SEN)为0.80[95%CI(0.75,0.84)],合并特异度(SPE)为0.75[95%CI(0.71,0.79)],阳性似然比(PLR)为3.60[95%CI(2.57,5.05)],阴性似然比(NLR)为0.17[95%CI(0.08,0.37)],SROC曲线下面积(AUC)为0.895。经直肠剪切波弹性成像辅助下穿刺诊断前列腺癌的研究亦是5篇,汇总分析后,其合并SEN为0.86[95%CI(0.83,0.88)],SPE为0.84[95%CI(0.82,0.85)],PLR为5.81[95%CI(3.07,10.99)],NLR为0.14[95%CI(0.04,0.49)],SROC曲线下面积(AUC)为0.924。结论经直肠剪切波弹性成像在前列腺癌诊断中有较好临床应用价值,且可作为经直肠超声引导下前列腺穿刺的辅助方法。     

Evaluation of elastography combined with serological indexes for hepatic fibrosis in patients with chronic hepatitis B

AIM To investigate the value of ultrasound elastography combined with serological indexes in diagnosing liver fibrosis and assessing its severity.METHODS A total of 338 chronic hepatitis B(CHB) patients were divided into a disease group(patients with hepatic fibrosis) and control group(subjects without hepatic fibrosis). The disease group was further divided into S1-S4 according to the degree of fibrosis. Independent risk factors for hepatic fibrosis were analyzed using multivariate logistic regression. The diagnostic values of hepatic fibrosis from different indicators were compared using receiver operating characteristic(ROC) curves. The combination of elastography and serological indexes was explored to assess the severity of hepatic fibrosis.RESULTS The multivariate logistic regression analysis results revealed that shear wave velocity(SWV), hyaluronic acid(HA), type Ⅳ collagen(CⅣ) and aspartate aminotransferase-to-platelet ratio index(APRI) significantly affected the occurrence of hepatic fibrosis. The ROC curve revealed that the accuracy of the diagnosis of hepatic fibrosis for SWV and HA were 87.3% and 84.8%, respectively. The accuracy of SWV combined with HA was 88.9%. The multiple linear regression analysis revealed that SWV, aspartate aminotransferase(AST)/alanine aminotransferase(ALT), HA, CⅣ, APRI and fibrosis index based on the 4 factor(FIB-4) were screened as statistically significant independent factors. The established regression equation was: Fibrosis level =-4.046 + 1.024 × SWV + 1.170 × AST/ALT + 0.011 × HA + 0.020 × CⅣ + 0.719 × APRI + 0.379 × FIB-4. CONCLUSION SWV combined with serological indexes can improve the accuracy of diagnosis for CHB hepatic fibrosis. Serum indexes can help diagnose the degree of hepatic fibrosis.
