Development and evaluation of an online monitoring single-particle optical particle counter with polarization detection.

We developed a single-particle optical particle counter with polarization detection (SOPC) for the real-time measurement of the optical size and depolarization ratio (defined as the ratio of the vertical component to the parallel component of backward scattering) of atmospheric particles, the polarization ratio (DR) value can reflect the irregularity of the particles. The SOPC can detect aerosol particles with size larger than 500 nm and the maximum particle count rate reaches ∼1.8 × 10 particles per liter.

Comparison of ultrasound-guided and traditional localisation in intraspinal anesthesia: a systematic review and network meta-analysis.

Objectives: The optimal puncture technique for neuraxial anaesthesia in different populations is unclear. We sought to obtain data from randomised controlled trials comparing the impact of ultrasound-guided technology and traditional positioning technology on the success rate of neuraxial anaesthesia.

Design: Systematic review and network meta-analysis using study populations, interventions, intervention comparisons, outcome measures and study types.

Effect of perioperative acupoint electrical stimulation on macrophages in mice under operative stress.

The strong perioperative stress response caused by surgical anesthesia can significantly suppress immune function, and the body is in a state of immunosuppression for 3 to 4 days after surgery, which leads to an increase in the probability of postoperative infection. Traditional Chinese medicine believes that acupuncture points can "reconcile yin and yang", promote the recovery of immune function, and help reduce the incidence of postoperative infection. Macrophages are an important type of immune cells that participate in the body's innate immunity.

[The interaction between soluble CD73 and 90-day mortality from patients with non-septic shock and sepsis shock: a secondary analysis from the prospective FINNAKI study].

Objective: Fundamental researches have shown that soluble CD73 (sCD73) can inhibit inflammatory response and limit excessive tissue damage caused by continuous immune cell activation. A Finnish prospective, observational study of acute kidney injury (FINNAKI) showed no association between sCD73 and 90-day mortality in sepsis patients. Clinical data of this study was used for secondary analysis to explore whether the relationship between sCD73 and 90-day mortality was consistent in septic shock and non-septic shock patients.

[Relationship between "1-hour serum lactate" level and 30-day mortality in critical care patients in intensive care unit].

Objective: To investigate the relationship between 1-hour lactate (1 h Lac) and 30-day mortality in critical care patients in intensive care unit (ICU).

Methods: A retrospective, observational cohort study was performed with adult critical patients (age ≥ 16 years old) having lactate records within 1 hour after ICU admission from Medical Information Mart for Intensive Care-III database (MIMIC-III). According to the 1 h Lac level, the patients were divided into three groups: < 2 mmol/L, 2-4 mmol/L, and > 4 mmol/L groups.
