Review[Application of laboratory diagnostic technologies for SARS-CoV-2: current progress and prospect].
Since the outbreak of COVID-19 pandemic, the detection capability has been improving and the detection techniques have been evolving with innovations. qRT- PCR and mNGS, which represent the current mainstay diagnostic technologies, play key roles in disease diagnosis and monitoring of virus variation. The detection technologies based on serum and plasma IgM and IgG antibodies are important for auxiliary diagnosis. ⋯ These techniques all have great potential for future development and application for pathogen detection. In this review the authors summarize the basic rationales, technical characteristics and the current application of the SARS-CoV-2 detection techniques.

Comparative Study[Comparison of four scoring systems for predicting ICU mortality in patients with sepsis].
To evaluate the value of Sequential Organ Failure Assessment (SOFA), Simplified Acute Physiology Score Ⅱ (SAPS-Ⅱ), Oxford Acute Severity of Illness Score (OASIS) and Logistic Organ Dysfunction System (LODS) scoring systems for predicting ICU mortality in patients with sepsis. ⋯ The scores of SOFA, SAPS-Ⅱ, OASIS, and LODS can predict ICU mortality in patients with sepsis, but SAPS-Ⅱ and OASIS scores have better predictive value than SOFA and LODS scores.

[Radiomics models based on non-enhanced MRI can differentiate chondrosarcoma from enchondroma].
To develop and validate radiomics models based on non-enhanced magnetic resonance (MR) imaging for differentiating chondrosarcoma from enchondroma. ⋯ The radiomics models based on T1WI and T2WI-FS non-enhanced MR imaging can be used for the differentiation of chondrosarcoma from enchondroma.

[Prevention and control of SARS-CoV-2 infection in clinical laboratories: implementation of contingency plan and postpandemic response strategies].
The outbreak of COVID-19 has currently been under control in China, but now the disease has rapidly evolved into a global pandemic. We formulated a prevention and control plan for clinical laboratories responsible for detection of the novel coronavirus infection. ⋯ We found that the layout of most clinical laboratories (including gene amplification laboratories for clinical samples) was inadequate in response to a major outbreak and did not meet the requirements for biosafety protection and etiology and serology testing; and laboratory staff showed insufficiencies in their awareness regarding biosafety protection; the functions and status of the laboratory in the fever clinic need to be enhanced to increase its detection capacity; the high density of military personnel, the low level of automation of clinical laboratory equipment, and the lack of biosafety cabinets and personal protective equipment all limit the performance of diverse military operations and major overseas missions. In view of these problems, we propose the following strategies and recommendations: the clinical laboratory needs to standardize the design and staff management according to the standards of P2 laboratory; the detection capacity and staffing of fever clinic laboratory in hospitals need to be strengthened, and a separate clinical gene amplification laboratory can be optimal; for those clinical gene amplification laboratories that fail to meet these standards, reconstruction and upgrade should be made according to the requirements of biosafety protection; for the clinical laboratory in the military medical system, in addition to enforcement of biological safety protection of the staff, sufficient supply of medical materials and biological safety equipment should be ensured and biological safety cabinets should be routinely equipped if possible.
