Benign biliary strictures(BBS) have different etiologies, and the most common causes are strictures secondary to iatrogenic and ischemic injury after hepatobiliary and transplantation surgery. Fibroblast proliferating activity, extracellular matrix overdeposition and scar proliferation are closely related to BBS. The mechanism of development of BBS involves a variety of cells, cytokines and extracellular matrix. In recent years, biological treatment is emerging as an effective option for BBS, but the clinical application is not yet mature and the curative effect needs to be evaluated further in the future.

Objective To investigate and analysis the prevalence rate of hospital infection and community infection,and to reduce the incidence of hospital infection.Methods First we investigated hospitalized patients in September 9,2013 by two ways which in-clude bedside investigation and reviewing the medical records;and then described the prevalence case of infection and the usage of antimicrobial agent by descriptive approach.Results Seven hundred and seventy patients were investigated with the rate of 100.00%;18 patients were hospital infection cases,the infection rate was 2.34%;most of the hospital infection cases was occur in lower respiratory tract;228 patients were community infection cases.The infection rate was 29.61%;the primary affected areas of community infection were respiratory and gastrointestinal tract;the structure of hospital infection pathogens were almost the same with the community infection,most of them were G- bacteria;186 patients were used antimicrobial agent in that day,the usage rate was 24.16%.Conclusion Promoting the managements of high risk departments and susceptible affected areas,making relevant rules of operation are the focus of our works in the future.
