P 24 h group and RSV intervention group were significantly increased. The percentage of ASC-positive area in intestinal epithelium of RSV intervention group was significantly lower than that of CLP 6 h group [(15.22±2.73)% vs. (19.88±2.67)%, P < 0.05], and the expressions of NLRP3 and caspase-1 were significantly lower than those of CLP 24 h group [(9.31±1.37)% vs. (13.19±1.92)%, (19.57±3.92)% vs. (27.28±6.33)%, both P < 0.05].

After sepsis, high concentration of RSV could inhibit the activation of NLRP3 inflammasome by activating SIRT1, thereby reduce the expression of caspase-1 and ASC, and inhibit the secretion of inflammatory factors to reduce the inflammatory response.

To evaluate the effects of noise, bright light and mechanical stimulation on sleep, blood-brain barrier and cognitive function in septic rats.

Forty male Sprague-Dawley (SD) rats were selected and intraperitoneal injection of 10 mg/kg lipopolysaccharide (LPS) was used to establish sepsis model. 0, 30, 45, 60, 75 dB noise stimulation or 0, 50, 100, 200, 400 Lux light stimulation were given to rats (all n = 4). The serum levels of cortisol and melatonin, and the cerebral content of Evans blue (EB) were measured 96 hours after the stimulation to determine the optimal intensity of intervention. The other 40 SD rats were randomly divided into control group (Con group), LPS group, noise intervention group (LPS+60 dB group), 200 Lux light intervention group (LPS+200 Lux group) and mechanical stimulation group (LPS+MS group), with 8 rats in each group. The open fields test and fear conditioning test were used to evaluate the exploratory behavior and cognitive function 96 hours after corresponding stimulation. The vs. 0.97±0.20), and the expression of cleaved caspase-3 was significantly increased (caspase-3/β-actin 0.56±0.06, 0.39±0.04, 0.72±0.12 vs. 0.20±0.03), with statistically significant differences (all P < 0.05).

60 dB noise, 200 Lux light or mechanical stimulation for 96 hours could inhibit the secretion of serum melatonin, promote the secretion of cortisol, and activate neuroinflammation in septic rats, and lead to neuronal apoptosis in hippocampus and hyper-permeability of blood-brain barrier, which in turn could cause sleep disturbance and cognitive impairment.

To investigate the roles and underlying mechanisms of mixed lineage kinase domain like (MLKL)-mediated inflammatory response induced by NOD-like receptor protein 3 (NLRP3) inflammatory corpuscles in the acute lung injury (ALI) after sepsis.

Eighteen BALB/c mice were randomly divided into sham operation group (Sham group), cecal ligation and perforation (CLP)-induced sepsis model group (CLP group) and specific inhibitor Necrostatin-1 intervention group [CLP+Nec-1 group, Necrostatin-1 solution (20 mg/kg) was injected intravenously 10 minutes before modeling], with 6 mice in each group. The mice were sacrificed by neck amputation at the 2nd day after operation, and the serum and lung tissue samples were collected. The morphological changes of lung tissue were observed by hematoxylin-eosin (HE) staining. The water content of lung tissue was detected by dry-wet weight method. The pulmonary vascular permeability was measured by Evans blue (EB) staining. The protein expressions of MLKL and NLRP3 in the lung tiss0)%], pulmonary vascular permeability [EB content (mg/L) 7.90±0.00 vs. 11.82±1.15], protein expressions of p-MLKL and NLRP3 in lung tissue (p-MLKL/GAPDH 0.13±0.03 vs. 0.34±0.04, NLRP3/GAPDH 0.18±0.04 vs. 0.47±0.07), and the level of serum IL-1β (ng/L 113.81±6.62 vs. 183.56±9.61) were all significantly decreased (all P < 0.01).

MLKL-NLRP3-mediated necroinflammation was significantly up-regulatedin the lung tissue of septic mice, which could be attenuated by specific inhibitor Necrostatin-1.

To investigate the effect of fluid resuscitation and circulatory support, directed by different target mean arterial pressure (MAP), on abdominal blood flow, gastrointestinal function and inflammatory response in septic shock patients with hypertension.

A prospective randomized controlled study was conducted. Hypertensive patients with septic shock admitted to the department of intensive care unit (ICU) of Liuzhou People's Hospital from January 1, 2019 to May 31, 2020 were enrolled. Patients were randomly divided into the low MAP groups (low standard group, LS group) or high MAP group (high standard group, HS group). Selleck CDK inhibitor According to the Surviving Sepsis Campaign Guidelines in 2016 and the updated guideline in 2018, all patients were given treatment of primary disease, fluid resuscitation, supportive management. The target MAP was 65-70 mmHg (1 mmHg = 0.133 kPa) in LS group, and was 75-80 mmHg in HS group. Acute gastrointestinal function injury (AGI) classification was performed on the 1st, 3rd and 7th day. T of inflammatory factors, and diminish the duration of using vasopressors and the amount of fluid.
Maintaining a low target mean arterial pressure (65-70 mmHg) in hypertensive patients with septic shock can improve blood supply of superior mesenteric artery, protect the gastrointestinal function, reduce the level of inflammatory factors, and diminish the duration of using vasopressors and the amount of fluid.Sepsis is caused by various pathogens and toxic factors, which can lead to multiple organ dysfunction. The underlying mechanism of sepsis appears to be complex, involving epigenetic reprogramming, metabolic failure, immune dysfunction, neuroendocrine system disorders, coagulation abnormalities, tissue or organ failure, and many other scientific issues. With our deep understanding of the host reaction and development of sepsis, it is of great significance to explore predicative markers and therapeutic targets according to the atypical characteristics of sepsis, thereby contributing to the reduction of morbidity and mortality of sepsis.
