ABSTRACT
The paper introduces the design and implementation of residents online medical examination report query system based on cloud platform,including the system architecture,process,data structure,security and necessary controls,etc.This system makes it able for the residents to check their medical examination reports and corresponding video pictures whenever and wherever possible on the Internet.
ABSTRACT
We herein report a witnessed cardiopulmonary collapse of a patient with difficult mask ventilation and near-impossible laryngoscopy-cum-intubation in the critical care unit. The airway was successfully rescued with a laryngeal mask airway Supreme™, followed by an open, crash tracheostomy by the otolaryngologist.

Group II chaperonins, which assemble as double-ring complexes, assist in the refolding of nascent peptides or denatured proteins in an ATP-dependent manner. The molecular mechanism of group II chaperonin assembly and thermal stability is yet to be elucidated. Here, we selected the group II chaperonins (cpn-α and cpn-β), also called thermosomes, from Acidianus tengchongensis and investigated their assembly and thermal stability. We found that the binding of ATP or its analogs contributed to the successful assembly of thermosomes and enhanced their thermal stabilities. Cpn-β is more thermally stable than cpn-α, while the thermal stability of the hetero thermosome cpn-αβ is intermediate. Cryo-electron microscopy reconstructions of cpn-α and cpn-β revealed the interwoven densities of their non-conserved flexible N/C-termini around the equatorial planes. The deletion or swapping of their termini and pH-dependent thermal stability assays revealed the key role of the termini electrostatic interactions in the assembly and thermal stability of the thermosomes.

This study was aimed to explore prognostic significance of minimal residual disease (MRD) detection in patients with acute myeloid leukemia (AML) by multiparameter flow cytometry (MCF). Leukemia-associated immunophenotype (LAIP) of newly diagnosed AML patients were determined by 4-color 5 antibody panels and patients with sensitive LAIP were chosen for MRD detection. 601 bone marrow samples from 95 patients were acquired after treatment and MRD were considered positive by the critical normal value plus twice standard deviation in normal bone marrow specimen. The patients were divided into three groups and the clinical significance was analyzed every 2 months within initial 6 months after induction treatment. The results showed that the relapse rate and relapse-free survival (RFS) rate were all significantly different between MRD positive and MRD negative patients in the three groups (p < 0.05). Patients with MRD positive had a median relapse-free survival time of 11 months, 11.5 months and 11 months at 1 - 2, 3 - 4 and 5 - 6 months respectively, while all patients with MRD negative were not observed to reach median release-free survival time (p < 0.05). Furthermore, the clinical significance was analyzed after induction and one course of consolidate treatment, the relapse rate of MRD positive and MRD negative patients were 57.14% versus 0% and 91.67% versus 2.27% respectively (p = 0.000 and p = 0.000). It is concluded that MRD detection by multi-parameter flow cytometry can predict outcome of AML patients, which should be continuously monitored after treatment.
