[Objective] To explore the risk factors for mortality of bloodstream infections in the patients with hematologic diseases,so as to provide evidence for reasonable and effective application of treatments.[Methods] The clinical data of 242 cases of bloodstream infections who were hospitalized from Jan 2012 to Jun 2016 were analyzed retrospectively,then the analysis was performed for risk factors.The statistical analysis was processed by SPSS 19.0.[Results] A total of 266 strains of pathogens were isolated,including 99 strains of gram-positive bacteria,accounting for 37.2％,and 164 strains of gram-negative bacteria,accounting for 61.7％.Multivariate analysis showed that the significant independent risk factors for mortality were active states of hematologic diseases (P =0.007,OR =5.622,95％ CI 1.586 ～ 19.924),presentation with septic shock(P =0.007,OR =4.978,95％ CI 1.560 ～15.884),cardiac insufficiency (P =0.001,OR =11.878,95％ CI 2.760 ～ 51.120),level of albumin less than 35 g/L (P =0.036,OR =3.468,95％ CI 1.087 ～ 11.066),polymicrobial infection (P =0.010,OR =6.024,95％ CI 1.540 ～ 23.563),and Staphylococcus haemolyticus (P =0.001,OR =19.308,95％ CI 3.392 ～ 109.888)/Enterococcus (P =0.002,OR =15.266,95％ CI 2.817 ～82.728) infection.The survival curves show that the inappropriate initial antimicrobial therapy group or presentation with any one of the independent risk factors had a lower probability of survival than the control group.[Conclusions] Bloodstream infections in patients may cause high mortality rate,so it is necessary that we use antibiotic reasonably and spare no effort to reduce the mortality rate by appropriate application of antimicrobial therapy and effective intervention of the risk factors.

Objective:To explore the relationship between the polymorphisms in gene FGFR1, FGF10, FGFI8 and the nonsyndromic cleft lip with or without cleft palate (NS CLP) in Chinese population. Methods: Genomic DNA was isolated from peripheral lymphocytes of 75 patients with NS CLP and their parents and 75 unimpaired healthy children. The polymorphisms in FGFRI gene rs13317, p. E467K, p. M3691 and p. S393S, FGF10 gene rs1448037 and FGFI8 gene rs4043716 were detected by applying three-dimensional (3-D) polyacrylamide gel microarray technology. The data were performed using statis-tical analysis : the genotype frequenc+ y and allele frequency between patients with NSCL/P and control subjects were performed. Haplotype relative risk (HRR) , family based association test (FBAT) , and transmission disequilibrium test (TDT) in nuclear family were performed. Results: There were no poly-morphism in FGFR1 gene p. E467K, p. M369I and p. $393S site, the corresponding base was all G. The polymorphisms of rs13317 and rs1448037 were detected and their genotype frequency and allele frequen-cy showed no significant difference between 75 patients with NSCL/P and 75 normal children. TDT, HRR and FBAT were also no significant differences. The genotype frequency of gene FGF18 rs4043716 showed significant difference, but allele frequency were no significant difference. TDT, HRR and FBAT were also no significant difference. Conclusion: Our studies suggest an association between gene FGF18 rs4043716 and the NS CLP in Chinese population, and no association among gene FGFR1 rs13317, p. FA67K, p. M3691, p. S393S and gene FGF10 rs1448037.
