To investigate the risk factors of citrate accumulation in patients with liver failure treated with regional citrate anticoagulated continuous renal replacement therapy (RCA-CRRT).
The clinical data of liver failure patients with RCA-CRRT admitted to department of intensive care unit (ICU) of Nantong Third People's Hospital from January 2017 to June 2020 were retrospectively analyzed. The selected patients were divided into citrate accumulation group and control group according to whether there was citrate accumulation (serum total calcium/free calcium ratio ≥ 2.4) during CRRT. The age, acute physiology and chronic health evaluation II (APACHE II), mean arterial pressure (MAP), norepinephrine (NE) dose, blood lactic acid (Lac) concentration, liver function status, citrate dose, filter time and prognosis of the patients were compared between the two groups. Unconditional Logistic regression was used to analyze the risk factors for citrate accumulation.
Among 48 patients with RCA-CRRT and liver failure, 2lation.
In patients with tissue hypoperfusion and severe liver function damage, citrate anticoagulation should be avoided or the dosage of citric acid should be reduced, in order to avoid citrate accumulation.
To investigate the value of quantitative electroencephalography (qEEG) in the evaluation of thrombolytic efficacy in acute cerebral infarction.
A prospective cohort study was conducted. Ninety-four patients with acute cerebral infarction who received intravenous thrombolysis admitted to the department of emergency of Qinhuangdao First Hospital from October 2019 to September 2020 were enrolled. The relative energy values of δ, θ, α and β waves in qEEG before and 2 hours, 24 hours and 7 days after intravenous recombinant tissue plasminogen activator (rt-PA) thrombolysis were dynamically monitored, and the power ratio index [DTABR, DTABR = (δ+θ)/(α+β)] was calculated. The National Institutes of Health stroke scale (NIHSS) score was also recorded. The reduction of NIHSS score ≥ 3 or the disappearance of neurological symptoms were regarded as effective thrombolytic therapy. The changes of DTABR before and after thrombolysis in patients with effective and ineffective thrombolysis were analyzed, and the correlat= 0.691, P < 0.01).
The quantitative index of qEEG, DTABR, can accurately and quickly monitor the process of thrombolysis in acute cerebral infarction, and can effectively evaluate the effect of thrombolysis in patients.

To investigate the protective effect and potential mechanism of cordycepin on renal proximal tubular cells injury induced by lipopolysaccharide (LPS).
Renal proximal tubular cells NRK-52E were incubated on a cell culture plated at a density of 1×10
/mL for experiment, then divided into control group (Ctrl group), LPS group (cells were stimulated with 1 mg/L LPS), 10 μmol/L or 20 μmol/L cordycep in intervention groups (LPS+C 10 group and LPS+C 20 group). Cell viability was measured using cell counting kit-8 (CCK-8) reagent. The level of intracellular reactive oxygen species (ROS) was detected by 2',7'-dichlorofluorescin diacetate (DCFH-DA) staining. https://www.selleckchem.com/products/ly3200882.html The protein expressions of inflammatory factors intercellular cell adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), interleukin-1β (IL-1β), and nuclear factor-κB (NF-κB) were detected by Western blotting.
Compared with the Ctrl group, LPS significantly inhibited NRK-52E cell viability, increased intracellular ROS, and up-regulated thDH 1.561±0.074 vs. 2.364±0.097, VCAM-1/GAPDH 1.920±0.098 vs. 2.866±0.135, IL-1β/GAPDH 1.563±0.179 vs. 2.358±0.107, NF-κB p-p65/GAPDH 1.596±0.148 vs. 2.559±0.166, all P < 0.05).
Cordycepin could significantly increase the survival rate of NRK-52E cells, reduce intracellular ROS level, and inhibit inflammation, and the anti-inflammation effect can be related with NF-κB pathway.

To explore the damage of the intestinal mucosal barrier of septic rats by the activation of NOD-like receptor family, pyrin domain-containing 3 (NLRP3) inflammasomes and the role of Ulinastatin (UTI) on the expression of intestinal nuclear factor-κB (NF-κB)/NLRP3 inflammasome signaling pathway in septic rats.
According to the random number table method, 64 male Wistar rats were divided into sham operation group (Sham group), cecal ligation and puncture (CLP) group, UTI treatment group (100 kU/kg UTI was intraperitoneally injected 1, 6, 12 and 18 hours after CLP), and UTI pretreatment group (100 kU/kg UTI was given 1 hour before CLP), with 16 rats in each group. The survival of rats was observed after 24 hours, and the blood was collected from abdominal aorta at 24 hours after modeling, then rats were killed and their ileum tissues were taken. Hematoxylin-eosin (HE) staining was used to observe histopathological changes and Chiu score. The levels of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β) amucosa may be related to inhibiting the activation of NLRP3 inflammasomes in the intestinal mucosa, but UTI pretreatment has no obvious advantage compared with UTI treatment.
Intestinal barrier dysfunction in sepsis may be related to the activation of NLRP3 inflammasomes in the intestinal mucosa. The protective effect of UTI in the intestinal mucosa may be related to inhibiting the activation of NLRP3 inflammasomes in the intestinal mucosa, but UTI pretreatment has no obvious advantage compared with UTI treatment.
To analyze the risk factors and clinical characteristics of liver injury in patients with sepsis and to provide a reference for early recognition, early diagnosis, early intervention, and improve the survival rate of patients.
The clinical data of sepsis patients admitted to the department of general intensive care unit (ICU) of the Second Affiliated Hospital of Zhejiang University School of Medicine from July 2014 to October 2020 were retrospectively analyzed. According to the occurrence of acute liver injury, patients with sepsis were divided into the liver injury group and the non-liver injury group, and the differences of demographic data, history, history of primary diseases, laboratory indicators on the first time of admission, treatments, the severity of the disease and other indicators were compared and analyzed. Logistic regression was used to analyze the risk factors for sepsis-related liver injury.
A total of 527 patients with sepsis were enrolled, and 129 patients with acute liver injury, accounting for 24.
