ABSTRACT

<p><b>OBJECTIVE</b>To analyze the infection characteristics of sputum and venous blood pathogen in the patients with hematological malignancies and respiratory symptom in the Hematology Department in tropical region and to investigate its drug-resistance so as to provide etiological evidence for clinical treatment.</p><p><b>METHODS</b>The pathogens and their drug-resistance of 2466 samples in the patients with hematological malignancies and respiratory symptom in the Department were analyzed retrospectively from January 2013 to November 2017. The samples were collected from sputum and venous blood.</p><p><b>RESULTS</b>The sputum sample culture in patients with hematologic diseases showed that 224 strains were isolated, out of them 98 strains (43.75%) were fungi mainly candida albicans (41 strains); and then 88 Gram-negative strains (39.28%), among them the main pathogenic bacteria were Escherichia coli(22 strains) and klebsiella Klebsiella pneumoniae(12 strains); and then 38 Gram-positive strains (16.96%), among them the main pathogeni-bacteria were Enteroccocus (14 strains) and Gram-positive bacilli (14 strains). The blood samples culture of patients with hematologic diseases showed that 61 strains were isolated, out of them the isolated rate of Gram-positive bactetia was higherst, which accounted for 55.74%(34/61), mainly including staphylococcus lominis (19 strains); and the isolated rate of Gram-negative bacteria was 44.26% (27/61), among them main pathogenic bacteria was Klebsiella pneumoniae (12 strains). The resistance test of pathogenic bacteria to drugs showed that the resistant rate of Gram-negative bacteria to tigecycline, imipenem and atl-962 duenner was lowest, while the Gram-positive pathogenic bacteria such as Enterococcus, Gram-positive bacilli and Staphylococcus aureus were sensitive to vancomycin, tigecycline and linezolid was high.</p><p><b>CONCLUSION</b>the patients in hematology department are infected easily in the hospital in tropical region. The main pathogens are fungal strains in the respiratory tract of patients with hematological malignancy according to the sputum culture results. The clinician in tropical regions should choose suitable antibiotics for anti-infective therapy, which is different from the situation in North China or other northern areas.</p>

ABSTRACT

Objective:To retrospectively analyze the routine clinical laboratory parameters for hepatocellular carcinoma,in an attempt to search for parameters for diagnosis of hepatocellular carcinoma(HCC).Methods:The pre-operation clinical labo- ratory data,such as tumor makers,and serological biochemical indices,hepatitis B virus(HBV)infection markers,and HBV DNA titers,were collected from 828 patients who were pathologically diagnosed as having HCC;then the correlation between these data with tumor size and the pathological grades of HCC was analyzed.Results:It was found that 97.9% of the 828 pa- tients were infected with HBV and 70.9% of them were accompanied by liver fibrosis.We also found that the tumor size was correlated with albumin(ALB),globulin(GLB),A/G,aspartate aminotransferase(AST),ratio of aspartate to alanine amin- otransferase(AST/ALT),gamma-glutamyl transferase(GGT),alkaline phosphatase(ALP),alpha-L-fucosidase(AFU),al- pha-fetoprotein(AFP)and tumor grades;meanwhile,the pathological grades of tumor was correlated to prealbumin(PALB), GGT and tumor size(all P
