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.

The nucleotide sequences of the PAP gene and PAPⅡ gene in the root of Phytolacca americana were determined by reverse transcription polymerase chain reaction and PCR. The gene comprises 942bp and 933bp respectively, encoding 313 amino acids and 310 amino acids. When PAP gene and PAPⅡ gene sequences in the root were compared with those in the spring leaves and summer ones, the highest similarity 100% and 99. 8% were observed respectively. They both had one open reading frame . Analysis of the two sequences showed, in fact, they belonged to one species.

Mitochondrial 16S rRNA gene and COⅠ gene fragments were amplified and sequenced from 4 wild populations of Portunus trituberculatus. Respectively, 524bp and 658bp long partial gene fragments of the 16S rRNA gene and the COⅠ gene were obtained. A high percentage of A+T base composition in the two sequences was observed, which was similar to the results of studies on drosophila, shrimp, crab and other invertebrates.
