OBJECTIVE To investigate the profile of pathogen of infection in kidney disease patients. METHODS Pathogen of infection in kidney disease patients in our hospital from Jan 2004 to Feb 2006 was retrospectively investigated. RESULTS A total of 240 pathogen strains were isolated from 223 cases.Of the 240 isolated strains the rate of strains of Gram-negative bacilli was 55.4%,that of the Gram-positive cocci was 26.3%,the rate of fungi was 10.0% and that of the Gram-positive bacilli was 8.3%.The positive rate of Escherichia coli was the highest followed by Haemophilus influenzae.54.2% Of isolates were from urine,21.3% from sputum.The isolated pathogens resisted at different degrees to antibiotics which were used frequently in clinic.The rate of polyinfection was not high. CONCLUSIONS Pathogen of infection in kidney disease patients is mainly Enterobacteriaceae.The isolates mainly are E.coli which is multi-resistant.It mainly causes the urinary infections.

OBJECTIVE To investigate the changes in pathogenic bacteria and drug resistance in nosocomial(septicemia).METHODS The blood samples of inpatients were cultured with blood culture apparatus,VITEK-AMS were used to identify the pathogenic bacteria and conduct drug resistance test.RESULTS The proportion of(Gram-positive) cocci had been increasing,coagulase negative staphylococcus increased significantly,but the(proportion) of Staphylococcus aureus decreased significantly.The proportion of Gram-negative bacteria and fungi decreased too.Vancomycin and imipenem were the highest susceptible to Gram-positive and Gram-negative(bacteria),respectively.CONCLUSIONS Gram-negative bacteria are the major pathogens in nosocomial septicemia.But Gram-positive cocci had been increasing in the past years.Coagulase negative staphylococcus is the main pathogen in nosocomial septicemia.pathogenic bacteria are higher resistant to the commonly used antibiotics.

Objective:To investigate the relationship between the protein expression of C-MYC, bcl-2 and bcl-6 and the clinicopathological characteristics in patients with de novo CD5-positive diffuse large B cell lymphoma (CD5 +DLBCL). Methods:Fifty seven cases of de novo CD5 +DLBCL were collected at Ruijin Hospital Affiliated to Shanghai Jiaotong University School of Medicine from February 2013 to September 2018. The hematoxylin-eosin stained slides were reviewed, and immunohistochemical (IHC) staining and FISH were used to analyze the relationship between C-MYC, bcl-2, bcl-6 expression and the clinicopathologic characteristics of patients. Results:Among these 57 cases, 27 were male and 30 were female. The age of onset was 35-99 years old. The IHC expression rates of C-MYC, bcl-2 and bcl-6 were 50.9% (29/57), 84.2% (48/57), and 75.4% (43/57) respectively; and co-expression rate of C-MYC and bcl-2 proteins was 40.4 (23/57). There was no significant correlation between protein expression and patients′ genders, clinical stage, the level of serum LDH,β2 microglobulin, IPI,B symptoms, bone marrow involvement and central nervous system recurrence ( P>0.05). Univariate analysis showed that the median OS of C-MYC negative patients was significantly longer than C-MYC positive patients ( P<0.05); and the median OS of patients without double expression was significantly longer than that of patients with positive expression ( P<0.05), and bcl-6 positive patients had longer median OS than bcl-6 negative patients ( P<0.05). There was no significant correlation between prognosis and bcl-2 protein expression ( P>0.05) . Cox multivariate analysis showed C-MYC protein expression was an independent predictor of OS in de novo CD5 +DLBCL ( P<0.05). Conclusions:Bcl-2 protein expression has no effect on the prognosis in de novo CD5 +DLBCL whereas bcl-6 expression is correlated with good prognosis. C-MYC protein expression could be used as an independent and effective index to predict the prognosis of patients with de novo CD5 +DLBCL.However, the relationship between protein expression and gene rearrangement of C-MYC, bcl-2 and bcl-6 needs to be further explored.
