目的 探讨甲状腺Bethesda Ⅲ类(AUS/FLUS)结节的诊断原因,以及亚分类在预测结节恶性风险(risk of malignancy,ROM)中的价值。方法 收集356例Bethesda Ⅲ结节患者,对其诊断原因, ROM及亚分类进行总结分析。结果 在97例手术切除标本中,72例恶性肿瘤均为甲状腺乳头状癌(papillary thyroid carcinoma,PTC),Bethesda Ⅲ类的ROM为74.2%。影响PTC诊断的主要原因有病灶小、穿刺细胞量稀少、缺乏乳头状结构及细胞核特征不典型;次要原因有间质显著纤维化或钙化、涂片不合格、固定不当、染色不佳及细胞学诊断经验欠缺等。Bethesda Ⅲ类的亚分类:132例为低风险组,其中12例手术切除,ROM为8.3%;122例为高风险组,其中70例手术切除,ROM为92.9%;102例为中风险组,其中15例手术切除,ROM为40.0%;高风险组和低/中风险组之间的差异有统计学意义(P＜0.05)。结论 Bethesda Ⅲ类的诊断具有一定的主观性和经验性,而对Bethesda Ⅲ类结节进行风险相关的亚分类,有助于实现更好的ROM分层并改善此类病变的临床管理。

Objective To investigate the diagnostic causes of Bethesda Ⅲ (AUS/FLUS) thyroid nodules and the value of subcategories in predicting risk of malignancy (ROM) of thyroid nodules. Methods The data of 356 cases of Bethesda Ⅲ nodules were collected, and the causes, ROM and subcategories were summarized. Results In 97 resected specimens, 72 were diagnosed as papillary thyroid carcinoma (PTC), and the ROM of Bethesda Ⅲ was 74.2%. The main factors affecting the diagnosis of PTC were small lesions, few puncture cells, atypical nuclear features and lack of papillary structure. Secondary factors included significant interstitial fibrosis or calcification, unqualified smear, improper fixation, poor staining and lack of cytological diagnosis experience. According to the subcategories of Bethesda Ⅲ, 132 cases were included in low-risk group, nodules of 12 cases in the group were resected, which ROM was 8.3%; 122 cases were included in high-risk group, nodules of 70 cases were resected, which ROM was 92.9%; 102 cases were included in middle-risk group, nodules of 15 cases were resected, which ROM was 40.0%. The differences between high-risk group and low/medium-risk group were statistically significant (P＜0.05). Conclusion The diagnosis of Bethesda Ⅲ is subjective and empirical in some degree, and the risk related subcategories of Bethesda Ⅲ nodules is helpful to achieve better ROM stratification and improve the clinical management of the disease.

目的 探讨妇女阴道健康状况及阴道分泌物清洁度、线索细胞及唾液酸酶法检测细菌性阴道病(BV)的相关性。方法 随机抽取2013年4月—2014年6月本院妇科疑似细菌性阴道病患者标本835例,分别采用生理盐水直接涂片及分泌物直接涂片进行革兰氏染色两者相结合检查清洁度、线索细胞;唾液酸酶法检测BV。结果 清洁度Ⅰ～Ⅱ占27.55%,BV阳性率为2.40%,线索细胞检出率1.32%;清洁度Ⅲ～Ⅳ占72.45%,病原菌阳性率为46.23%,其中BV阳性率为30.55%,线索细胞检出率为23.48%。结论 清洁度异常率比正常率偏高;清洁度正常不一定没有细菌性阴道病; BV的出现严重威胁妇女身体健康,正确的诊断有重要意义,唾液酸酶法检测BV虽有快速、操作简单、显色结果易判断,但温度、时间、取材问题等受多种因素影响。

Objective To explore the correlation between the health of women's vagina and vaginal cleanness, clue cells and bacterial vaginosis(BV)which is tested by the sialic acid enzymatic method. Methods Randomly select 835 suspected cases of bacterial vaginosis in our hospital gynecology department in April 2013-June 2014. Every case was respectively done saline direct smear and vaginal secretion direct smear gram staining to check vaginal cleanness and clue cells. BV is tested by sialic acid enzymatic method. Results The cleanness of I-II accounted for 27.55%, BV positive rate was 2.40%, the positive rate of clue cells was 1.32%;the cleanness of degree III-IV accounted for 72.45%, the positive rate of pathogenic bacteria was 46.23%, the positive rate of BV was 30.55%, the positive rate of clue cells leads to 23.48%. Conclusion The rate of abnormal vaginal cleanness is higher than the normal.The nomal vaginal cleaness does not show no bacterial vaginosis. The emergence of BV seriously affects women's health, so the correct diagnosis is of great importance. Although the of the saliva acid enzyme to test BV is fast, operates easily and the color results are easily to be judged, but it can be influenced by other factors such as temperature, time, materials issues.
