Objective To study the clinical value of serum SA,EMA and GPDA in the diagnosis of gastric cancer.Methods To detect serum SA,EMA and GPDA in 30 patients with gastric cancer patients,25 patients with gastric precancerous lesions and 35 patients with non-atrophic gastritis with electronic gastroscope and pathological examination confirmed,compared the differences betwwen the groups,and analyze the relationship between the expressions of them and clinical biology of gastric carcinoma.Results The serum concentrations of SA and GPDA in gastric carcinoma are remarkably higher than those in non-atrophic gastritis and gastric precancerous lesions(P0.05).The concentrations of GPDA in non-atrophic gastritis group are age-related(P0.05).Conclusion It has an important reference value for the diagnosis of gastric cancer to detect serum SA and GPDA.SA and GPDA together can improve the accuracy of the diagnosis of gastric cancer.EMA serum possibly has no diagnostic value for gastric cancer.The expressions of SA,GPDA in serum are related to the biology behaviors of gastric carcinoma,and the concentrations of SA,GPDA in serum is helpful in judging metastasis and recrudescence,and monitoring prognosis.

Objective To investigate the current situation of nursing staffs in second-class and tertiary hospitals of Nanchang City and influencing factors in order to provide a basis for the management and research of patients safety.Methods The convenience cluster sampling method was adopted to extract the whole nursing staffs from 7 hospitals(4 second-class hospitals and 3 tertiary hospitals)in Nanchang City as the research subjects.Then the multiple regression method was adopted to analyze the influencing factors of patients safety culture in the second-class and tertiary hospitals of Nanchang City.Results The advantage fields of cognition of the nursing staffs in the second-class hospitals on the patients safety culture were the intra-department teamwork,expectation actions of managers for promoting safety,organizational learning and continuous improvement,feedback and communication of mistakes,while the fields needing to be improved were the communication openness,personnel allocation,non-penalty reactions on mistakes;the advantage fields in the tertiary hospitals were same to those in the second-class hospitals,and the fields needing to be improved included the inter-department cooperation,personnel allocation,non-penalty reactions on mistakes.Conclusion The cognition of nursing staffs in 7 hospitals of Nanchang City on the patients safety culture is in a higher level,but insufficiency still exists,partial fields need to be continuously improved.
