ADA，CEA、CA对癌性与结核性胸水的鉴别

目的：探讨腺苷氨酶（adnosine deaminase,ADA),癌胚抗原（carcinoembryonic antigen,CEA),糖类抗原（carbohydrate antigen,CA)对癌性与结核性胸水的鉴别意义,方法：对3年来确诊的结核性胸水53例,癌性胸液43例患者的胸水标本进行检测,结果：在结核性胸液中,ADA均值显著高于其在癌性胸水中的均值（P＜0．01）,而且检测的敏感性,特异性和准确性较其他指标均高（P＜0．01）,在癌性胸液中,CEA,CA50,CA125,CA199,CA211的均值较它们在结核性胸液中的均值显著升高（P＜0．01,P＜0．05）,结论：在癌性与结核性胸水的鉴别中,对ADA和CA211的联合检测,在胸水性质的鉴别中比其它指标更有意义。

直肠癌壁外血管侵犯影像学评价的研究进展

直肠癌壁外血管侵犯是影响直肠癌病人预后的重要因素,术前准确诊断壁外血管侵犯,可指导治疗方案的制订,从而改善病人预后和远期生存。MRI检查和CT检查是术前评估直肠癌的主要检查手段。笔者将对影像学检查在直肠癌壁外血管侵犯评价的作用进行综述。     

Metachronous ileal cancer after surgery for ascending colon cancer in a patient with Lynch syndrome: A case report

Introduction and importanceColorectal surveillance via colonoscopy in patients with Lynch syndrome reduces the mortality of colorectal cancer. On the other hand, it is unclear whether surveillance for other malignancies, including small bowel cancer, is beneficial. We report a patient with Lynch syndrome who developed ileal cancer after surgery for ascending colon cancer.Case presentationA 47-year-old man visited our hospital for a check-up for positive fecal occult blood. He was diagnosed with ascending colon cancer and met the clinical criteria for the diagnosis of Lynch syndrome based on his past and family history. The Bethesda markers demonstrated high-frequent microsatellite instability. Laparoscopy-assisted right hemicolectomy was performed. He received follow-up colonoscopy the next year, which revealed ileal cancer near the anastomosis. He underwent resection of the second cancer via a laparoscopic approach, and has been free from recurrence for five years.Clinical DiscussionSmall bowel cancer has a dismal prognosis because a high percentage of patients were diagnosed at advanced stages. The diagnosis of metachronous ileal cancer by the first follow-up colonoscopy after surgery for ascending colon cancer offered a long disease-free survival in our patient.ConclusionThe clinical course suggested the importance of inspecting the small bowel in Lynch syndrome patients, especially when colorectal cancer is diagnosed.     

乳腺肿瘤的影像学诊断进展

乳腺肿瘤属女性的常见病之一,且乳腺恶性肿瘤患者的病死率较高。随着医疗技术水平的不断提升,超声、X线等影像学技术已被广泛应用于乳腺肿瘤的诊断中,尤其是MRI、核医学等新技术在乳腺肿瘤的早期诊断中具有较好的应用效果。该研究对乳腺肿瘤的影像学诊断进展进行综述。     

陪检方式在胸痛患者诊疗过程中效果评价

目的 探究陪检在胸痛患者诊疗过程中的应用效果。方法 选择2019年江苏某三甲医院急诊科收治的110例胸痛患者为研究对象,依据是患者就诊时是否有专人陪检分为实验组与对照组,进行病例对照研究。实验组由医务人员陪检,完成各项辅助检查,对照组患者依据临床医师的指示自行完成各项检查,患者病情严重程度采用TIMI评分进行评价。统计分析两组患者的医疗安全不良事件发生率、患者对医疗服务满意度差异,评价陪检方式的应用效果。结果 110例研究对象,其中男性53例,女性57例,年龄范围49~80岁,平均年龄（62±6.10）岁。实验组（陪检组）56例,对照组（无陪检组）54例。两组人群平均年龄t=-0.323,P=0.747,性别统计学检验x2=1.295,P=0.255。患者病情严重程度评价TIMI评分两组统计学检验t=1.513,P=0.134。实验组不良事件发生数量5例次（8.92%）明显低于对照组16例次（29.6%）,统计学检验x2=7.62,P=0.006（P<0.05）;患者满意实验组94.64%,对照组81.48%,两组统计学检验x2=4.57,P=0.033(P<0.05)。结论 陪检在胸痛患者诊疗过程中具有较好的应用效果,值得推广运用。     

剪切波弹性成像与FNA-Tg对甲状腺乳头状癌侧颈部淋巴结转移的诊断价值

目的：探讨剪切波弹性成像(shear wave elastography,SWE)与细针穿刺洗脱液甲状腺球蛋白(fine-needle aspiration washout thyroglobulin,FNA-Tg)对甲状腺乳头状癌侧颈部淋巴结转移的诊断价值。方法：回顾性分析159例经病理证实为甲状腺乳头状癌(papillary thyroid carcinoma,PTC)的患者资料,对颈部211枚可疑淋巴结进行常规超声、SWE参数平均值(E_mean)、FNA-Tg检查,以术后病理结果为金标准,比较各检测方法的诊断效能。结果：(1)SWE E_mean转移组[(50.96±27.66) kPa]高于非转移组[(32.20±17.34) kPa],差异有统计学意义(t=8.761,P<0.01)。受试者工作特征(receiver operating characteristic,ROC)曲线分析表明,SWE E_mean最佳诊断阈值为40.42 kPa时对PTC颈部淋巴结转移预测价值较高,曲线下面积(area under...
