Systemic lupus erythematosus with acquired hemophilia A: A case report and literature review.

Systemic lupus erythematosus (SLE) complicated with acquired hemophilia A (AHA) is a rare condition with frequently delayed diagnosis and a high mortality rate, so it is necessary to strengthen the understanding of this disease. In this study, the characteristics and treatment in 1 case of SLE complicated by AHA is reported and analyzed, and a literature review is conducted. The patient was a 29-year-old young female with a 10-year history of SLE, the main clinical manifestation was severe abdominal bleeding.

Risk factors for progression of juvenile-onset non-radiographic axial spondyloarthritis to juvenile-onset ankylosing spondylitis: a nested case-control study.

Objective: To evaluate the clinical characteristics of juvenile-onset non-radiographic axial spondyloarthritis (nr-axSpA) and to investigate risk factors associated with progression to juvenile-onset ankylosing spondylitis (JoAS).

Methods: A nested case-control study was conducted using the retrospectively collected data of 106 patients with juvenile-onset nr-axSpA (age at disease onset, <16 years) in the Clinical characteristic and Outcome in Chinese Axial Spondyloarthritis study cohort. Baseline demographic and clinical characteristics and prognosis were reviewed.

Interleukin-1β Disturbs the Proliferation and Differentiation of Neural Precursor Cells in the Hippocampus via Activation of Notch Signaling in Postnatal Rats Exposed to Lipopolysaccharide.

Infectious exposure during the perinatal period may predispose to permanent neurological disorders in later life. Here we investigated whether changes in interleukin-1β (IL-1β) are associated with cognitive dysfunction in later life of septic neonatal rats through suppression of neurogenesis in the hippocampus. Sprague-Dawley rats (1-day old) administered lipopolysaccharide (LPS) showed upregulated expression of IL-1β and IL-1 receptors in the hippocampus.

Microglia-derived IL-1β contributes to axon development disorders and synaptic deficit through p38-MAPK signal pathway in septic neonatal rats.

Background: Axon development plays a pivotal role in the formation of synapse, nodes of Ranvier, and myelin sheath. Interleukin-1β (IL-1β) produced by microglia may cause myelination disturbances through suppression of oligodendrocyte progenitor cell maturation in the septic neonatal rats. Here, we explored if a microglia-derived IL-1β would disturb axon development in the corpus callosum (CC) following lipopolysaccharide (LPS) administration, and if so, whether it is associated with disorder of synapse formation in the cerebral cortex and node of Ranvier.

[Effect of axonal developmental disorders in the corpus callosum on the neurological function after birth in septic neonatal rats].

Objective: To observe the axonal development in the corpus callosum of septic neonatal rats, and its effect on the neurological function after birth.

Methods: Forty-eight 1-day-old Sprague-Dawley (SD) rats were randomly divided into two groups: control group and sepsis group, with 24 rats in each group. The rat model of sepsis was reproduced by intraperitoneal injection of 1 mg/kg lipopolysaccharide (LPS), and the rats in control group were injected with an equal volume of phosphate buffered saline (PBS).

[Microbial characteristics in culture-positive sepsis and risk factors of polymicrobial infection in ICU].

Objective: To investigate the clinical characteristics and pathogenic microorganisms in culture-positive sepsis, to identify its risk factors, and evaluate the prognosis on polymicrobial infection in intensive care unit (ICU).

Methods: A descriptive retrospective study was conducted. Clinical data of patients aged ≥ 18 years, diagnosed as culture-positive sepsis, and admitted to six ICUs of Guangdong General Hospital from October 12th, 2012 to December 1st, 2014 were enrolled.

IL-1β induces hypomyelination in the periventricular white matter through inhibition of oligodendrocyte progenitor cell maturation via FYN/MEK/ERK signaling pathway in septic neonatal rats.

Neuroinflammation elicited by microglia plays a key role in periventricular white matter (PWM) damage (PWMD) induced by infectious exposure. This study aimed to determine if microglia-derived interleukin-1β (IL-1β) would induce hypomyelination through suppression of maturation of oligodendrocyte progenitor cells (OPCs) in the developing PWM. Sprague-Dawley rats (1-day old) were injected with lipopolysaccharide (LPS) (1 mg/kg) intraperitoneally, following which upregulated expression of IL-1β and IL-1 receptor 1 (IL-1R1 ) was observed.

Efficacy and safety of tigecycline for the treatment of severe infectious diseases: an updated meta-analysis of RCTs.

Objectives: To assess the efficacy and safety of tigecycline in comparison with other antimicrobial treatments for infectious diseases.

Design: Databases of PubMed, Embase and the Cochrane Library were searched through Feb. 2015.
