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.

結果 所有胰液標本均成功抽提出DNA亚洲女生被插下体免费看网站，30例胰腺疾病病人胰液標本同時進行了K-ras基因突變和p16基因啟動子區(qū)5′CpG島甲基化檢測久久婷婷88A片，其中20例胰腺癌病人胰液中K-ras基因突變率為70%（14/20），p16基因甲基化率為35%（7/20）国产老妇伦国产熟女老妇视频，8例慢性胰腺炎中K-ras基因突變率為25%（2/8）igao视频为爱搞点激情入口，2例胰腺囊腺瘤病人中K-ras基因突變率為50%（1/2），慢性胰腺炎和胰腺囊腺瘤病人胰液中無p16基因甲基化激情文学网。

Methods K-ras gene point mutation and its style at codon 12 of Patu 8988 cell were detected by using PCR-SSP and sequence analysis.

方法順序特異引物聚合酶鏈反應法和基因測序檢測Patu8988細胞K-ras點突變形式人人干黄视频，根據點突變形式設計并合成硫代反義寡核苷酸（K-ras mutation ASODN）作用Patu 8988，通過噻唑藍比色法檢測細胞生長情況国模吧高清女模专业网站；流式細胞術檢測K-ras蛋白表達和細胞凋亡；逆轉錄-聚合酶鏈反應檢測K-ras mRNA表達水平你懂滴视频；以Patu8988細胞建立裸鼠胰腺癌模型觀察K-ras mutation ASODN在體內的抗腫瘤效果黄色视频在线网站2。

In vitro, K-ras mutation ASODN could apparently inhibit the growth of Patu 8988 cells （ in a certain degree of dose-dependent and time-dependent manner）,induce apoptosis and decrease the expression of K-ms protein and K-ras mRNA in contrast with SODN, RODN and control groups.

針對K-ras基因第12密碼子點突變的反義寡核苷酸可明顯抑制人胰腺癌Patu 8988細胞生長，促進細胞凋亡国产一级A视频，其機制可能是通過下調K-ras蛋白和K—ras mRNA表達而起作用https://igao16com。
