沃辛瘤35例临床分析

目的：探讨沃辛瘤的发病及临床诊治特点。方法：对近10年来收治的35例经病理证实的沃辛瘤患者的临床资料进行统计分析。结景：肿瘤全部发生在腮腺。多见于50～70岁的男性，平均年龄56．9岁，男女之比为10．7：1。肿瘤位于腮腺后下极31例，占88．5％。同侧多灶性或双侧发生4例，占11．4％。吸烟者占全部病例71．4％(25例)。治疗采用全腮腺或浅叶 肿物切除术，无复发病例。诘论：腮腺后下部淋巴结与其中的迷走涎腺组织是肿瘤发生的组织学基础，吸烟和高龄免疫功能改变可能是肿瘤发生的主要刺激因素，采用肿瘤与不同范围腮腺组织切除术可达治愈效果。

Effect of iodine isotope on the pituitary-thyroid and immune systems of children living on the territories polluted by radionuclides

Examination of thyroid function and immune status of children living on the territories polluted by radionuclides in 1993–1994 revealed¹³¹I-dependent thyroid autoimmune reactions. These data indicate a possible effect of¹³¹I on the pituitary-thyroid and immune systems of children living on the radiation controlled territories.

人肝癌及癌周组织中γ-谷氨酰转肽酶、甲胎蛋白癌胚抗原的表达

用丫-谷氨酞转肽酶-甲胎蛋白(GGT-AFP)双染色法研究了人肝癌及癌周组织中GGT,AFP的表达,同时观察了癌胚抗原(CEA)的分布.20例肝癌组织中,11例GGT阳性,10例AFP阳性.13例CEA阳性.在癌周组织中,6例GGT阳性,2例AFP阳性,20例CEA阳性.证实肝细胞癌可表达GGT,AFP,增生结节属癌前期病变,与肝癌的发生有关,GGT,AFP的增高与肝癌密切相关,CEA无特异性.     

The Effect of Acute and Chronic Exercise on Thyroid Hormones in Obesity

Abstract Thyroid hormones were measured before, during and after acute exercise (60 min) or physical training (3 months) in obese women. Thyroid stimulating hormone concentration increased during acute work and decreased immediately after. No changes were seen during the two following days. An increase was seen after ten days as well as after three months of physical training. Thyroxine concentrations showed no changes. 3,5,3′-Triiodothyronine decreased slightly immediately after acute exercise, and after three months of physical training, 3,3′,5′-triiodothyronine (reverse triiodothyronine) increased slowly during and after acute exercise. A negative correlation was found between changes in fasting insulin and thyroxine and a positive correlation between changes in blood pressure and triiodothyronine after training. Lack of agreement in previous reports is probably due to methodological differences such as methods more or less susceptible to fatty acid interference, and thyroid hormones changing differently during acute work and before and after physical training. The duration of the study may also be of importance, even 3 months possibly being too short for attaining equilibrium in thyroid homeostasis.     

甲状腺手术205例分析

Is ERCP manometry useful in the choice of treatment of stones of the common bile duct?

Summary To verify the appropriateness of sphincterotomy as the treatment of choice of choledocholithiasis, since 1980 we have been using endoscopic retrograde cholangiopancreatographic (ERCP) manometry of the sphincter of Oddi (SO). This method allows direct investigation of SO motor activity and provides useful information regarding the presence of benign papillary stenosis (BPS). Thirty-four patients were investigated because the radiological examination indicated BPS might be present. Of these, 20 had common bile duct (CBD) stones, while the remaining 14 presented with biliarylike pain and one or more of the following: CBD dilation (larger than 12 mm); emptying of the ERCP contrast medium took longer than 45 min; abnormal liver function tests. Moreover, 8 healthy volunteers served as controls. Our results show that the incidence of SO motor anomalies is very low in the presence of choledocholithiasis, while it is substantial in patients with suspected SO dysfunction. These observations would suggest that, unlike the traditional view, BPS is rarely secondary to biliary lithiasis. Therefore, most of the sphincterotomies performed that are based on the assumption of underlying SO pathology should be considered unnecessary. Under these circumstances, the physiological role of a functioning SO has induced us to advocate sphincterotomy, surgical or endoscopic, in selected cases only.     

长链非编码RNA lnc-CCDC33-1:1在甲状腺乳头状癌中的表达及临床意义

目的：检测lnc-CCDC33-1:1在甲状腺乳头状癌（PTC）中的表达,并分析其临床意义。方法：选取2021年11月至2022年3月杭州市萧山区第一人民医院收治的120例PTC患者,收集120例PTC组织及30例癌旁正常甲状腺组织。采用qRT-PCR检测lnc-CCDC33-1:1在PTC组织及癌旁组织中的表达。分析本地队列和TCGA队列中lnc-CCDC33-1:1表达水平与PTC患者临床病理因素的相关性。采用受试者工作特征（ROC）曲线评价lnc-CCDC33-1:1对PTC的诊断价值。结果：与癌旁正常甲状腺组织比,lnc-CCDC33-1:1在PTC组织中表达明显升高（P ＜0.001）。ROC曲线显示曲线下面积为0.803（95%CI =0.736～0.869,P ＜0.001）。本地队列显示lnc-CCDC33-1:1 表达与PTC肿瘤大小（P =0.048）、腺外侵犯（P =0.019）、T分期（P =0.011）和淋巴结转移（P =0.009）相关,TCGA组数据显示lnc-CCDC33-1:1表达水平与PTC腺外侵犯（P =0.036）和淋巴结转移（P ＜0.001）相关。结论：lnc-CCDC33-1:1在PTC中表达异常升高,与PTC高危特征相关,可能是潜在的诊断标志物和治疗靶点。
