needle-point.
4.Methods According to the K-ras point mutant type (CGT, GTT and GAT) in pancreatic adenocarcinoma, three kinds of sequence special primer (SSP) for ploymerase chain reaction were designed, where K-ras gene fragment was amplified from frozen or paraffin embedded pancreatic adenocarcinoma tissues, fine needle aspiration sample from pancreatic adenocarcinoma and pancreatic juice of patients with pancreatic carcinoma. K-ras point mutation of the amplified product was detected by gel electrophoresis.
6.Therapeutics of inject of endoscope stiffening agent is to point to inside to remedy of tailor-made inject needle inject is used below lens (stiffening agent) Yu Qu piece inside vein or by vein, make Qu Zhangjing arteries and veins produces esophagus out-of-the-way, prevent and cure thereby esophagus varicosity burst bleeds.
