ObjectiveTo explore the value of ultrasonography in the diagnosis of gastrointestinal stromal tumors (GISTs). MethodWe retrospectively analyzed the clinical data of 110 patients with surgical pathology confirmed GISTs between January 2008 and December 2013. All the patients underwent routine ultrasound examination. Thirty-two patients accepted oral contrast enhanced bowel ultrasonography, and 5 patients underwent trans-rectal ultrasound (TRUS). ResultsA total of 107 cases were detected out of the 110 cases of GISTs by ultrasonography, and the other three cases were missed. Among the 107 cases, 104 were shown to be masses, and 3 had thick gastric or intestinal walls. Among the 104 masses, hypo-echoic lesions were found in 73, heterogeneous lesions were found in 25, and hyper-echoic lesions were found in 6; 30 cases of tumor were less than 5 cm in diameter, 54 were between 5 cm to 10 cm in diameter, and 20 were longer than 10 cm in diameter (including 5 were longer than 20 cm in diameter). In the 107 cases, 12 were found to have liver metastasis, 4 were detected to have abdominal lymph node enlargement, and 3 had ascites. Surgery and pathological results showed that among the 110 cases of gastrointestinal stromal tumors, 91 developed from the stomach and intestine and the other 19 were extra-gastrointestinal stromal tumors; 72 were at high risk, 21medium risk, and 17 low risk. ConclusionsThe detection rate of GISTs by ultrasonography is high, but the quantitative and qualitative diagnosis ability should be raised.
【摘要】 目的 用高频超声对正常女性乳腺健康体检，探讨其在临床及乳腺普查方面的应用价值。 方法 对2006年1月－2009年12月间7 532例健康女性乳腺体检声像图进行分析，并对各年龄段的乳腺病变超声结果分布情况进行统计。 结果 共检出乳腺病变2 861例（37.98%），正常者4 671例（62.02%）。所有受检者中，囊性病变1 904例（25.28%），实性病变944 例（12.53%），混合性病变13例（0.17%），伴有副乳者692例。囊性病变及实性病变单侧多于双侧，混合性病变均为单侧。常见病中，囊性病变多于实性病变，发病年龄分布在20～30岁及31～40岁年龄段。 结论 高频超声作为女性乳腺疾病的一种常规检查，能对乳腺占位性疾病提供较为准确的诊断，对乳腺癌早期发现、早期诊断、早期治疗提供一种科学依据。【Abstract】 Objective To explore the clinical value of high-frequency sonography for normal clinical breast examination in breast screening. Methods From January 2006 to December 2009, 7 532 healthy women underwent breast sonography. The results of sonography in the individuals with different ages were statistically analyzed. Results Breast lesions were found in 2 861 cases (37.98%) and the other 4 671 were healthy. Among all of the individuals, 1 904 cases (25.28%) had cystic lesions, 944 (12.53%) had solid lesions and 13 (0.17%) had mixed lesions. There were 692 cases of accessory mammary tissue. Unilateral cystic nodules and solid nodules were more common than bilateral ones, whereas mixed nodules were usually sunilaterally. Cystic nodules were more common than solid nodules. Most common onset of breast lesions is in the individuals with the age of 20-30 and 31-40 years. Conclusion High-frequency sonography, as an examination for normal clinical breast screening provides more accurate diagnosis and early detection of breast lesions, which can provide scientific evidence for early detection, diagnosis and treatment for breast cancer.
目的：通过超声对185例肾上腺肿瘤诊断及漏诊、误诊病例分析，寻找影响肾上腺肿瘤超声漏诊及误诊的因素。 方法：本文回顾性分析185例肾上腺肿瘤超声与病理的资料，对超声漏诊和误诊原因进行了分类、归纳和总结。结果：通过185例肾上腺肿瘤的超声检查，超声诊断出肾上腺病变122例，诊断正确率65.95%，明显低于相关文献报道，漏诊57例，误诊6例。漏误诊率(34.05%)，明显高于相关文献报道，综合分析其病理及影像学资料，将漏误诊原因归纳为五种：①左侧肾上腺肿瘤；②小于2.0 cm的肿瘤；③混合性回声的肿瘤；④临床及超声医师对肾上腺肿瘤认识不足；⑤误诊的主要原因是由于肿瘤巨大，造成定位困难。结论：通过对肾上腺肿瘤漏诊及误诊分析，可以提高超声诊断的准确性，降低漏误诊率。
ObjectiveTo evaluate the diagnostic value of ultrasound for gallbladder carcinoma (GA), in order to improve the ability of early ultrasonic and clinical diagnosis of GA. MethodsWe analyzed and compared the clinical data and ultrasonic results of 42 GA cases confirmed by surgery and pathology between January 2008 and December 2013, and summarized the classification, ultrasonographic features, and diagnosis of GA. ResultsAmong the 42 cases, 25 were correctly diagnosed by ultrasound (59.5%), among which 9 were thick-wall type, 11 were protrusion type and 5 were solid type. Seventeen cases were misdiagnosed (40.5%). Pathological results showed 14 cases of highly-differentiated adenocarcinoma, 16 of moderately differentiaed adenocarcinoma, 9 of poorly-differentiated adenocarcinoma, 2 of squamous adenocarcinoma and 1 of neuroendocrine carcinoma. ConclusionUltrasound is the preferred method for the diagnosis of GA because of its convenience, although the diagnostic accuracy is still not good and more efforts should be done.
【摘要】 目的 比较肠充盈超声检查法与常规经腹超声检查法在结直肠肿瘤中的诊断价值。 方法 对2008年6月-2009年6月64例经临床病理确诊的结直肠肿瘤患者分别经腹常规超声及肠充盈超声检查。在肠充盈状态下观察病变的形态，对病变进行定位并观察结直肠肿瘤的彩色多普勒血流信号。比较肠充盈超声检查法及常规经腹超声检查法在结直肠肿瘤的检出、定位和显示血流的能力的差异。 结果 常规经腹部超声检查发现32例结直肠肿瘤（32/64），病灶敏感性为50%； 肠充盈超声检查法发现病灶55例（55/64）， 病灶敏感性为85.9%。经腹常规超声检查的定位准确率为21.9%（7/32），肠充盈超声检查法对结直肠肿瘤的定位准确率为89.1%（49/55）。两种方法比较差异有统计学的意义（Plt;0.05）。 结论 肠充盈超声检查法在结直肠肿瘤的病变敏感性检出、定位准确性等方面优于经腹常规超声检查；而不同病理类型的结直肠肿瘤具有不同的超声声像图特征。【Abstract】 Objective To compare the diagnostic value between intraluminal contrast-enhanced hydrocolon ultrasonography and conventional transabdominal ultrasonography for of colorectal neoplasms. Methods The conventional transabdominal ultrasonography and hydrocolonic ultrasonography using an intraluminal contrast agent were performed on 62 patients from June 2008 to June 2009. The morphological features and location of the lesion were observed and the blood flow signals were observed. The different diagnostic value between conventional transabdominal ultrasonography and intraluminal contrast-enhanced hydrocolon ultrasonography was compared. Results The sensitivity of the intraluminal contrast-enhanced hydrocolon ultrasonography in the depiction of the colorectal neoplasms (55/64, 85.9%) was higher than that of the conventional transabdominal ultrasonography (32/64, 50%, Plt;0.05). And the accuracy of the intraluminal contrast-enhanced hydrocolon ultrasonography in locating the colorectal neoplasms (48/55, 87.3%) was higher than that of the conventional transabdominal ultrasonography (7/32, 53.2%, Plt;0.05). Conclusion Intraluminal contrast-enhanced hydrocolon ultrasonography is more valuable for colorectal neoplasms than conventional transabdominal ultrasonography in detecting and locating colorectal neoplasms. Colorectal neoplasms with different pathological types may have different ultrasonic features.

Methods Sonographic findings from 58 patients with pathologically proved adrenal myelolipoma from March 2005 to September 2010 were retrospectively analyzed. The size of the lesion, internal echo features, and characteristics of blood flow were observed and analyzed. Results In 28 patients with pathologically proved adrenal myelolipoma from March 2005 to December 2007, adrenal lesions was diagnosed in 23 with an accurate rate of 82.1%; adrenal myelolipoma was diagnosed in two with an accurate rate of 7.1%; missed diagnosed in one; misdiagnosed was in four. In 33 patients with pathologically proved adrenal myelolipoma from January 2008 to September 2010, adrenal lesions was diagnosed in 30 with an accurate rate of 90.9%; adrenal myelolipoma was diagnosed in 19 with an accurate rate of 57.6%; no missed diagnosed occurred; misdiagnosed was in three. The sonographic features in 52 lesions were smooth borders and homogeneous hyperechoic; no color Doppler flow signal inside was detected. Conclusion Adrenal myelolipoma has special sonographic features. Ultrasonography is a reliable imaging method for the diagnosis of adrenal myelolipoma.
Based on the PRISMA 2009 checklist, the study analyzed current status and reporting quality of systematic reviews of animal experiments, and consulted experts in relevant fields to form an initial entry pool of reporting checklists for systematic reviews of animal experiments in traditional Chinese medicine (PRISMA-ATCM). Then, the initial entry pool was improved through 2 rounds of Delphi expert consultation. Finally, the items were revised through the consensus meeting, and the final PRISMA-ATCM was formed. Of the 27 items on the PRISMA checklist, 12 were revised and expanded, specifically relating to TCM interventions and animal characteristics. The publication of the PRISMA-ATCM will improve the transparency and standardization of systematic reviews of animal experiments in Chinese medicine.
