Methods The clinical data of 8 patients of biliary cystadenoma and cystadenocarcinoma, 3 males and 5 females, aged 55.8 （26 ～ 71 ）, were analyzed retrospectively.

方法回顾分析8例肝内胆管囊腺瘤和囊腺癌的临床病理表现、诊治经验并结合文献资料进行讨论。

Objective To demonstrate the CT features of pancreatic cystadenoma and cystadenocarcinoma.

e#［摘要］目的：探讨胰腺囊腺瘤与囊腺癌的CT表现。

Methods Semi-quantitative RT-PCR was employed to analyze the polymerase β mRNA in 41 cases of epithelial ovarian carcinoma, 27 cases of serous cystadenocarcinoma, and 4 cases of mucinous cystadenoma, endometrioid tumor, and 31 cases of normal ovarian tissue.

采用含有内对照的半定量RT-PCR方法，检测41例卵巢癌患者（其中浆液性囊腺癌21例，黏液性囊腺癌13例，子宫内膜样癌7例）及正常卵巢组织31例pol βmRNA的表达。

METHODS: The clinical data of patients with hepatobiliary cystadenoma (n = 3) or hepatobili- ary cystadenocarcinoma (n = 4) admitted to our hospital from February 2003 to February 2007 were analyzed.

回顾性分析2003-02/2007-02中国医科大学附属第一临床医院收治的肝胆管囊腺瘤患者3例及肝胆管囊腺癌4例的临床资料。

They were male in 8 eases and female in 14. Pancreatic cystoadenoma was in 14 cases (63.30%) and pancreatic cystoadenocarcinoma in 8(36.3%). It was 1.7:1 between two groups. Tumor at the head of pancreas was 6 cases (27.21%). at body-tail 12 (54.5%). at tail 4 (18.1%). Local resection was performed in one case, pancreatic body-tailectomy pancreatoc1uodenectoni in 3, central pancreatectomy in 2 cases.

男8例，女14例。14例(63.3%)为胰腺囊腺瘤（浆液性6例、黏液性8例），8例(36.3%)为胰腺囊腺癌，两者之比为1.7：l肿瘤位于胰腺头部6例(27.2%)，胰腺体尾部12例(54.5%)，胰腺尾部4例(181%)行胰腺肿瘤局部切除术l例，肤腺体尾部切除术14例，胰头十二指肠切除术3例，胰腺中段切除术2例，囊肿－空肠Roux-Y吻合术1例，T管架桥胆－肠内引流术1例。

Results The DNA was obtained from PPJ through a nasopancreatic tube. Aberrant p16 methylation and K- ras gene mutation were detected in the same samples of PPJ. Sensitivity,specificity,positive predictive values,negative predictive values and accuracy of HE staining for pancreatic cancer were 40%,100%,100%,45.4% and 60.0%,respectively. Of the 20 cases of pancreatic cancer,K- ras gene mutation was detected in 14 (70%) and the p16 gene was shown to be methylated in 7 (35%). Of the 8 cases of chronic pancreatitis,K-ras gene mutation was detected in 2 (25%). Of the 2 cases of mucinous cystoadenoma of pancreas,K-ras gene mutation was detected in 1 (50%). Aberrant methylation of p16 was not detected in pancreatic juice samples from patients with chronic pancreatitis and mucinous cystoadenoma of pancreas.

结果 所有胰液标本均成功抽提出DNA，30例胰腺疾病病人胰液标本同时进行了K-ras基因突变和p16基因启动子区5′CpG岛甲基化检测，其中20例胰腺癌病人胰液中K-ras基因突变率为70%（14/20），p16基因甲基化率为35%（7/20），8例慢性胰腺炎中K-ras基因突变率为25%（2/8），2例胰腺囊腺瘤病人中K-ras基因突变率为50%（1/2），慢性胰腺炎和胰腺囊腺瘤病人胰液中无p16基因甲基化。

Species identification researchThrough female\'s body wax glands of the Dactylopius confususthe scanning electron microscope research,the results showed that:Dactylopius confususfemale prosopon wax gland hole single or in groups,the forehead 25-30 crowd, each group has 4-6 approximately,the chest approximately 120-125 crowd,each crowd of 4-6,the abdomen approximately 200 crowds,each crowd reaches 30 approximately.

种类鉴定的研究通过对胭脂虫雌成虫虫体蜡腺的扫描电镜研究，结果表明：胭脂虫雌成虫蜡腺孔单个或成群，头部约25—30群，每群具有4—6孔，胸部约120—125群，每群约4—6孔，腹部约200群，每群多达30孔。

Leaf blade 1.4-3.2 × as long as broad, base not decurrent on petiole

叶不具腺具点；叶柄狭翅；苞片疏生腺毛。

Methods:Thyroidectomy,total or subtotal lobectomy of thyroid had been performed at 716 patients with thyrotoxicosis, thyroid adenoma, nodule thyrocele and papillary thyroid cancer by UAS in place of the conventional method such as deligation suture and hematischesis through thecervical minimal incision.Results:Mean operating time with the UAS was 72(42～134) minutes.

使用超声刀代替传统方法（结扎和缝合作为主要切割、止血的方法）对716例毒性甲状腺肿、甲状腺腺瘤、结节性甲状腺肿以及分化型甲状腺癌等多种甲状腺疾病，通过颈部小切口进行部分甲状腺切除术或腺叶全切术或根治性切除手术。
