Objective To explore the significances of the endoscopic diagnosis for chronic atrophic and histological assessment gastritis (CAG). Method Five hundred patients with CAG were determined by gastroscopy and the samples of gastric mucosa were examined by the pathology. Results Among 500 cases of CAG by gastroscopy, 429 cases were similar with the pathologic results and the coincidence rate of diagnosis with endoscopy and pathology was 85.8%(429/500), 370 cases had a change of atrophic gastritis in cirumjacent mucosa. Conclusion The coincidence rate of diagnosis under endoscopy and pathology is quite good in CAG.

Objective To analyze the inpatients species changes of infectious disease hospital from 2001 to 2011 years in Taiyuan,and make relevant recommendations to the trends and prevention strategies for common infectious diseases.Methods The diseases species of the hospital from 2001 to 2011 years and the number of hospitalized patients were retrospectively counted and analyzed.Results The proportion of liver disease hospitalized was always more than 60％ in the ten years;The bacillary dysentery decreased from 4.23％ in 2006 to 0.96％ in 2011 ;The hospitalized patients with measles decreased significantly since 2009,and only 0.26％ in 2011 ;In 2008,hand-foot-mouth disease accounted for 3.42％ of the hospitalized patients,and it peaked in 2010,accounting for 7.51％ ; The number of hospitalized patients with rabies disease rised in 2011,accounting for 0.27％.Conclusion Liver disease is still the major infectious diseases of the hospital;The mumps,chicken pox,scarlet fever and other respiratory diseases as well as hand-foot-mouth disease is a common infectious disease threats to the health of infants and young children,and for the increasing trend of the number of patients with brucellosis hairtetracycline,the tetracycline and brucellosis drugs for children should be promoted to product and sale.The rabies vaccination knowledge should be popularized,and the incidence of rabies should be reduced.

Colorectal cancer is one of the most commonly seen malignant neoplasms in digestive tract.Most patients with colorectal cancer died of metastasis.The details of the metastasis-associated mechanisms are not elucidated completely.Recently,many genes that are involved in this course were detected.In this paper,the latest advances in those metastasis-associated genes and coding genes including C-myc,Ras,Her-2 ,p53,deleted in colorectal cancer gene (DDC),phosphatase and tensin homologue (PTEN),nm23 and other code genes,such as CD44,matrix metalloproteinases (MMPs) and mucins will be reviewed.
