目的 回顾性分析不同病理类型乳腺黏液腺癌的超声声像图特征,从而提高术前乳腺黏液腺癌不同亚型的超声诊断准确率。方法 分析43名患者共44例手术切除或穿刺活检证实为乳腺黏液腺癌病灶的声像图资料,包括病灶的边界、边缘、形态、回声类型、生长方向、钙化、后方回声、血流分级、腋窝淋巴结形态,并对病灶进行BI-RADS分类。将超声声像图特征与手术或活检后病理结果进行对比,总结出不同亚型的乳腺黏液腺癌的超声声像图特征。结果 44例乳腺黏液腺癌病理类型分为21例单纯型黏液腺癌和23例混合型黏液腺癌,混合型黏液腺癌大多数表现为病灶边界不清(73.9%)、边缘模糊毛刺(73.9%)、形状不规则(91.3%)、以及内部回声不均匀(87%)、病灶内钙化更多见(52.2%)。混合型黏液腺癌的淋巴结转移率明显高于单纯型黏液腺癌(P<0.05)。对比术前病灶的BI-RADS分类及术后病理诊断,超声对恶性病灶诊断准确率68%,单纯型黏液腺癌和混合型黏液腺癌的诊断准确率分别为48.6%、87%。结论 不同病理类型乳腺黏液腺癌间具有一些不同的声像图特征。混合型黏液腺癌大多数表现为病灶边界不清、边缘模糊毛刺、形状不规则、回声不均匀、病灶内钙化多见;单纯型乳腺黏液腺癌通常表现为边界清晰、形态规则、钙化少见、淋巴结转移少等良性肿块声像特征,超声对其误诊率较高,需提高警惕。

Objective Retrospectively evaluate the sonographic features of different types of mucinous breast carcinoma to improve the preoperative ultrasound diagnostic accuracy rate. Methods Sonographic features of 44 cases of MBC proven by pathological biopsy were analyzed, including the margin,lesion boundary,shape,echo pattern,lesion growth pattern, calcification, posterior acoustic feature,blood flow, lymph node form and data system(BI-RADS)classification for the lesion to sum up the different subtypes of breast ultrasonic ultrasonographic features of mucinous carcinoma. Results 21 cases of pure mucinous carcinoma (PMBC)and 23 cases of mixed mucinous carcinoma(MMBC)were founded. MMBC were more likely to have unclear boundary (73.9%), indistinct or spiculate of margin(73.9%), irregular shape (91.3%), heterogeneous internal echo (87%), more calcification in lesions(52.2%). Lymph node metastasis in MMBC was obviously higher than that of PMBC(P<0.05). Compared with preoperative of the BI-RADS classification and pathological diagnosis, ultrasonography in diagnosing accuracy rate was 68% in malignant lesions, 48.6% in PMBC and 87% in MMBC. Conclusion There are some different ultrasonographic characteristics in different types of breast mucinous carcinoma.MMBC are more likely to have unclear boundary, indistinct or spiculate of margin, irregular shape, more calcification in lesions. On the contrary, PMBC has a circumscribed boundary, abrupt interface edge, rare calcification, rare lymph node metastasis and are easily misdiagnosed as benign lesions. We should pay more attention to avoid misdiagnosis in ultrasonography.

目的 探讨直肠神经内分泌肿瘤的临床病理特征。方法 回顾性分析46例直肠神经内分泌肿瘤患者的临床病理资料,对不同病理分级的患者在性别、年龄、肿瘤直径、浸润深度、肝及淋巴结转移等方面进行比较。结果 直肠神经内分泌肿瘤男性多见,肿瘤多位于直肠中下段。免疫组化检测显示CgA、Syn、CD56阳性率分别为40.0%、97.8%、100%。36例Ki-67阳性指数≤2％,6例Ki-67阳性指数在3％～20％,4例Ki-67阳性指数＞20％。不同病理分级的肿瘤与患者年龄、肿瘤直径、浸润深度、淋巴结及肝转移相关,与性别不相关。结论 直肠神经内分泌肿瘤缺乏临床特异性症状,联合CgA、Syn和CD56染色可提高直肠神经内分泌肿瘤的诊断率。病理分级对预测肿瘤浸润深度、肝或淋巴结转移有重要参考价值。

Objective To investigate the pathological and clinical significance of 46 cases of rectal neuroendocrine tumors(NET). Methods Retrospectively analyzed the clinical and pathological feature of 46 patients with rectal NET, and assessed possible interactions between different pathological grades and gender, age, tumor diameter, depth of invasion, lymph node and liver metastasis. Results Rectal NET appeared more frequently in males than in females. Most tumors located in middle and distal third of rectum. The positivity rates of immunohistochemical marker CgA, Syn, CD56 were 40.0%, 97.8%, 100.0%, respectively. The cases of Ki-67 positivity rate under 2%, ranged between 3%-20%, above 20% were 36, 6, 4, respectively. Different pathological grades were significantly correlated with age, tumor diameter, depth of invasion, lymph node and liver metastasis, but not with gender. Conclusion Rectal NET had nonspecific symptoms. Combined immunohistochemical staining, such as CgA, Syn and CD56, was important in the evaluation of rectal NET. Pathological grading might be very useful for prediction of invasion depth, lymph node and liver metastasis.

Methods Healthy 30 male SD rats were randomly divided into 6 groups(n=5 in each group): ① control group without operation or intrathecal injection. ②CCI group without intrathecal injection. ③ intrathecal injection of rapamycin 10 μg(10 μL) 4 hours after CCI operation and the next 2 days once a day. ④ intrathecal injection of NS10 μL 4 hours after CCI operation and the next 2 days once a day. ⑤ intrathecal injection of rapamycin 10 μg(10 μL) 7 days after CCI operation and the next 2 days once a day.⑥ intrathecal injection of NS10 μL 7 days after CCI operation and the next 2 days once a day. Mechanical and thermal threshold were tested 1 day before the CCI operation and 2^th、4^th、6^th、8^th、10^th、12^th、14^th days after the CCI operation for all the rats. Lumbar segment of spinal cords was removed for determination of glial fibrillary acidic protein(GEAP) in spinal cord by immuohistochemistry dyeing and assay in the 14th day after CCI operation for all the rats. Results Mechanical and thermal hyperalgesia emerged on 4th day and maintained till 14th day after CCI operation(P<0.05). After intrathecal injection of rapamycin 4 hours or 7days after CCI, mechanical and thermal threshold significantly increased compared to intrathecal injection of NS(P<0.05).
