Objective:To compare the efficacy and adverse reactions of omeprazole and pantoprazole in the treatment of patients with peptic ulcer bleeding. Methods: Totally 362 cases of peptic ulcer bleeding were randomly divided into the control group and the observation group with 181 ones in each. The control group was treated by omeprazole 40mg in 0. 9% sodium chloride injection 100ml, ivd, bid, and the observation group was given pantoprazole 80mg in 0. 9% sodium chloride injection 100ml, ivd, bid. The treatment course was 3-6 days. The times of vomiting and melena, bleeding situation and bleeding stopping time in the two groups were observed and recorded, and the clinical efficacy, adverse drug reactions during the treatment and the expense of the two groups were also compared. Results:The bleeding amount on the first and third day in the observation group was significantly lower than that in the control group (P < 0. 05), the average bleeding stopping time and the average times of black stools and vomiting in the observation group were also significantly lower than those in the control group(P < 0. 05). The effective rate of the observation group was 92. 27%, that of the control group was 90. 61%, and the difference was not statistically significant (P >0. 05). The average daily cost of the observation group was significantly lower than that of the control group (P <0. 05). The difference in the incidence of adverse drug reactions of the two groups was not statistically significant (P > 0. 05). Conclusion:The efficacy of omeprazole and pantoprazole in the treatment of peptic ulcer bleeding was similar with high security. However, pantoprazole may reduce the times of vomiting and melena, shorten the bleeding time and decrease the treatment cost.

NAC(NAM/ATAF/CUC) protein plays an important role in plant growth and development, secondary cell wall formation and stress response. In this study, based on the sequencing data of Angelica dahurica, the NAC family was systematically analyzed using bioinformatics methods and its expression pattern was analyzed. Studies showed that 75 candidate genes had been selected from the NAC transcription factor family of A. dahurica, with the protein size of 148-641, all of which were unstable hydrophilic proteins. Most NAC proteins were localized in the nucleus, and had complete NAC domain. Phylogenetic analysis of NAC family proteins of A.dahurica and Arabidopsis thaliana showed that among the 17 subfamilies, NAC members were unevenly distributed in each subfamily, indicating that the evolution of species is developing in multiple directions. Among them, ANAC063 subfamily contained no NAC sequence of A. dahurica, which might be due to the functional evolution of the species. Analysis of protein transmembrane structure and signal peptide showed that NAC transcription factor could carry out transmembrane transportation, but its signal peptide function had not been found. Expression analysis showed that most transcription factors responded to abiotic stress and hormones to varying degrees, and the effects of hormones were obvious, especially ABA and IAA. In different organs of A. dahurica, most members of the NAC family had higher expression in root phloem, followed by root xylem. This study lays a foundation for further research on the function of A. dahurica NAC transcription factor and for solving the biological problems of A. dahurica.
