Objective To investigate the bacterial spectrum changes and characteristics of drug resistance of patients with severe acute pancreatitis (SAP) and to guide clinical proper use of antibiotics medicine .Methods Clinical specimens of 50 patients with SAP were analyzed including sputum ,blood , urine ,central venous catheter ,bile ,et al .Bacterial strains were regularly isolated and drug sensitivity test was made by disc diffusion method .Chi-square test was performed for statistical analysis .Results One hundred and fifty-six bacterial strains were isolated .The number of strains isolated from the sputum , blood ,pancreas and abdominal cavity ,bile ,urine tract ,surgical incision ,oral secretion was 51 ,37 ,24 , 23 ,11 , 8 and 2 , respectively . The most common bacterial strains were Acinetobacter baumannii , Escherichia coli ,Pseudomonas aeruginosa and Enterococcus f aecium ,the number of strains was 30 ,21 , 20 and 14 ,respectively .The drug resistance rate of Acinetobacter baumannii to imipenem and meropenem was no less than 90% .The drug resistance rate to cefoperazone/sulbactam was lower ,but still over 60% . The drug resistance rate of Escherichia coli to penicillins ,majority of cephalosporins and quinolones was over 90% . The drug resistance rate of Pseudomonas aeruginosa to partial cephalosporins was high (90% ) ,and the drug resistance rate to imipenem was also up to 65% . T he drug resistance rate of Enterococcus faecium to penicillin G and quinolones was up to 100% . No Enterococcus resistant to tigecycline ,vancomycin and linezolid was found .The infection rate of patients received invasive operation was higher than that of patients received no invasive operation .Conclusions The main bacteria of patients with SAP complicated with infection was Gram-negative bacteria ,which has high drug resistance .The common locations of infection were respiratory tract ,blood ,abdominal cavity ,biliary system and urinary tract .The infection in respiratory tract and blood may be related with invasive medical operations .

Surgery in combination with chemotherapy and radiotherapy is the standard of lung cancer treatment,but postoperative recurrence is very common which usually leads to higher mortality and lower life quality. Immunotherapy on post-operative patients fully mobilizes the body's defense mechanisms,activates the immune cells,and kills residual cancer cells. Current research on lung cancer immunotherapy mainly includes four categories:adoptive immunotherapy,dendritic cell vaccine,non-specific antigen immune therapy and anti-gen-specific vaccine. These studies show lung cancer immunotherapy intervention can effectively reduce postop-erative residual cancer cells,reduce postoperative recurrence rate,prolong survival,significantly improve the prognosis,and is worth spreading in clinical practice.
