Metatranscriptome of human lung microbial communities in a cohort of mechanically ventilated COVID-19 Omicron patients.

The Omicron variant of the severe acute respiratory syndrome coronavirus 2 (SARS‑CoV‑2) infected a substantial proportion of Chinese population, and understanding the factors underlying the severity of the disease and fatality is valuable for future prevention and clinical treatment. We recruited 64 patients with invasive ventilation for COVID-19 and performed metatranscriptomic sequencing to profile host transcriptomic profiles, plus viral, bacterial, and fungal content, as well as virulence factors and examined their relationships to 28-day mortality were examined. In addition, the bronchoalveolar lavage fluid (BALF) samples from invasive ventilated hospital/community-acquired pneumonia patients (HAP/CAP) sampled in 2019 were included for comparison.

[Autologous peripheral blood hematopoietic stem cell transplantation in the treatment of type 1 diabetic mellitus: a report of 16 cases].

Objective: To explore the efficacy and safety of autologous peripheral blood hematopoietic stem cell transplantation (APBHST) in patients with type 1 diabetes mellitus.

Methods: Hematopoietic stem cells were mobilized with cyclophosphamide and granulocyte colony stimulating factor for 16 patients with type 1 diabetes mellitus who admitted to our department during November 2009 to August 2010. And then stem cells were collected from peripheral blood by leukapheresis and cryopreservation.
