Objective:To analyze the biological characteristics, phylogeny and the taxonomic status of strain 7712 (=CGMCC 1.17031=NBRC 113783=KCTC 15766) isolated from a clinical blood sample.Methods:Strain 7712 was identified by the cultural properties, cellular and colonial morphology, physiological and biochemical reactions, matrix-assisted laser desorption ionization time-of-flight mass spectrometry system, and genome correlation index analysis. The genomic phylogenetic tree was construct to analyze the taxonomic position. The virulence factors and resistance genes of strain 7712 and related strains were then compared by the online virulence factor database and online comprehensive antibiotic research database respectively.Results:Strain 7712 was urease negative, gram-negative nonfermenters, which was identified as Ochrobactrum anthropi by VITEK GN card. The 16S rRNA gene analysis showed that the strain was closely related to the members of genera Ochrobactrum and Brucella. The phylogenetic tree showed that strain 7712 was clustered together with Ochrobactrum teleogrylli LCB8 T and Ochrobactrum haematophilum CCUG 38531 T, along with genus Brucella and other Ochrobactrum species. The genome relatedness indexes analysis showed that the average nucleotide identity between strain 7712 and Ochrobactrum teleogrylli LCB8 T was 98.16%, which was higher than the threshold for prokaryotic species. Genetic prediction showed that strain 7712 carried several virulence-related genes and resistance-related genes, of which the existence of OCH gene might be responsible to the resistance to cephalosporin. Conclusions:A case of human infection caused by Ochrobactrum teleogrylli is identified, which would help promote the understanding of biodiversity of genus Ochrobactrum.

BACKGROUND:
Red-cell transfusion is critical for surgery during the peri-operative period; however, the transfusion threshold remains controversial mainly owing to the diversity among patients. The patient's medical status should be evaluated before making a transfusion decision. Herein, we developed an individualized transfusion strategy using the West-China-Liu's Score based on the physiology of oxygen delivery/consumption balance and designed an open-label, multicenter, randomized clinical trial to verify whether it reduced red cell requirement as compared with that associated with restrictive and liberal strategies safely and effectively, providing valid evidence for peri-operative transfusion.
METHODS:
Patients aged >14 years undergoing elective non-cardiac surgery with estimated blood loss > 1000 mL or 20% blood volume and hemoglobin concentration <10 g/dL were randomly assigned to an individualized strategy, a restrictive strategy following China's guideline or a liberal strategy with a transfusion threshold of hemoglobin concentration <9.5 g/dL. We evaluated two primary outcomes: the proportion of patients who received red blood cells (superiority test) and a composite of in-hospital complications and all-cause mortality by day 30 (non-inferiority test).
RESULTS:
We enrolled 1182 patients: 379, 419, and 384 received individualized, restrictive, and liberal strategies, respectively. Approximately 30.6% (116/379) of patients in the individualized strategy received a red-cell transfusion, less than 62.5% (262/419) in the restrictive strategy (absolute risk difference, 31.92%; 97.5% confidence interval [CI]: 24.42-39.42%; odds ratio, 3.78%; 97.5% CI: 2.70-5.30%; P <0.001), and 89.8% (345/384) in the liberal strategy (absolute risk difference, 59.24%; 97.5% CI: 52.91-65.57%; odds ratio, 20.06; 97.5% CI: 12.74-31.57; P <0.001). No statistically significant differences were found in the composite of in-hospital complications and mortality by day 30 among the three strategies.
CONCLUSION:
The individualized red-cell transfusion strategy using the West-China-Liu's Score reduced red-cell transfusion without increasing in-hospital complications and mortality by day 30 when compared with restrictive and liberal strategies in elective non-cardiac surgeries.

Objective:To compare MRI characteristics between hepatic benign nodules and hepatocellular carcinoma (HCC) associated with Budd-Chiari syndrome(BCS).Methods:A retrospective study was conducted on 130 consecutive patients with BCS who were treated at the Affiliated Hospital of Xuzhou Medical University from January 2011 to June 2018. There were 67 males and 63 females, age ranged from 18 to 78 years, with median age was 46 years. There were 45 patients with HCC and 85 patients with benign liver nodules. This study aimed to compare the clinical characteristics of BCS patients with HCC and benign nodules, and to compare the MRI features (distribution, capsule, plain scan signal, enhancement pattern) between HCC and benign nodules. The receiver operating characteristic (ROC) curve was used to evaluate the efficacy of each of the indicators in the diagnosis of hepatocellular carcinoma.Results:The age and alpha-fetoprotein levels of the BCS patients with benign nodules were significantly lower than the BCS patients with HCC, while the international standardized ratio was significantly higher than the BCS patients with HCC (all P<0.05). Of the 130 BCS patients, there were 337 benign and 78 hepatocellular carcinomas nodules. The diameter of benign nodules was significantly smaller than HCC, and the proportions of benign nodules with encapsulation, fat content, cystic necrosis and hemorrhage were significantly lower than HCC (all P<0.05). The proportions of benign nodules with T 1 weighted imaging high signal, T 2 weighted imaging (T 2WI) low or equal signal and diffusion-weighted imaging (DWI) equal signal were significantly higher than HCC (all P<0.05). The proportions of benign nodules with washout appearance, arterial phase hyperenhancement and washout appearance were significantly lower than HCC (all P<0.05). The areas under the ROC curve for the diagnosis of HCC by DWI high signal and T 2WI high signal were 0.936 and 0.927, respectively, with sensitivities of 96.2% and 92.3%, specificities of 91.0% and 90.1%, respectively. Conclusion:The MRI features of BCS patients with benign regenerative nodules were significantly different from those of BCS patients with HCC. The washout appearance had a low specificity for the diagnosis of HCC.
