Objective To analyze clinical and radiological characteristics of intracranial hemorrhage in hematological diseases to improve the recognition of them. Methods Thirty-one clinical data of intracranial hemorrhage cases with hematological diseases were reviewed. The basic diseases, clinical and radiological manifestations, and risk factors of mortality were analyzed. Results Intracranial hemorrhage usually occurred in patients with acute myeloid leukemia (AML) or idiopathic thrombocytopenic purpura (ITP),and 13 and 6 cases, respectively, in this group. Most patients presented with headache, restlessness, nausea,vomiting, conscious disturbance and no localization sign by physical examination. CT or MRI images often revealed focus of errlysis. Compared with CT scan, a higher detection rate of ICH could be realized by MRI scan. The total mortality in this group of ICH patients was 71% (22/31). Fever, white blood cell >5×109/L,platelet <50×109/L, hyperimmunoglobulinemia and disturbance of blood coagulation were risk factors for ICH of this group of patients. The mortality was higher in patients with no less than 2 risk factors[86.4 % (19/22)vs 33.3 % (3/9)] (x2 = 8.718, P = 0.003). Conclusion ICH is a serious complication for hematological patients. MRI scan is good at improving the diagnosis of ICH. It is of high risk of death in patients with no less than 2 risk factors such as fever, white blood cell higher than 5×109/L, platelet less than 50×109/L,hyperimmunoglobulinemia and disturbance of blood coagulation.

Objective:To clarify the distribution and composition of drug-resistant genes of carbapenem-resistant Klebsiella pneumoniae (CRKP) in Qingdao City and to provide rationale for clinical application of antibacterial treatment by screening for carbapenemase phenotype and detecting resistance genes of CRKP. Methods:Fifty-four clinically isolated non-repeating CRKP from five Third Grade & Class A Hospitals in Qingdao City from October 2016 to September 2019 were collected. Kirby-Bauer method was used for drug sensitivity tests of commonly used antibacterial drugs; modified Hodge test was used for carbapenemase phenotypic screening; and polymerase chain reaction (PCR) was used to amplify blaKPC-2, blaNDM-1, blaOXA-48, blaIMP, blaVIM target genes. The amplified products were subjected to agarose gel electrophoresis. Results:Drug susceptibility tests showed that CRKP had the lowest resistance rate to amikacin (35.2%), followed by compound sinomine (53.7%), gentamicin (55.6%), levofloxacin (75.9%), and imipenem-cilastatin (88.9%); piperacillin-tazobactam, meropenem, cefotaxime, and cefoperazone-sulbactam were all higher than 90%. There were 43 positive strains in the modified Hodge test (the positive rate was 79.63%) and 11 negative strains. A total of 40 strains with carbapenemase resistance were detected by PCR resistance gene detection. The detection rate of target drug-resistant genes was 74.07%. Among them, 35 strains carry the KPC-2 gene, 7 strains carry the OXA-48 gene, 4 strains carry the NDM-1 gene, and 1 strain carries the IMP gene. All strains carrying the OXA-48 gene also carried the KPC-2 gene, which was not detected. Strains carrying the VIM gene were identified, and the remaining 14 strains did not detect the target carbapenem gene.Conclusion:The carbapenem-producing genes carried by CRKP in five hospitals in Qingdao City are mainly KPC-2, followed by OXA-48 and NDM-1.
