RESUMO
Objective:To investigate the efficacy and safety of sivelestat sodium in patients with sepsis.Methods:The clinical data of 141 adult patients with sepsis admitted to the intensive care unit (ICU) of the First Affiliated Hospital of Zhengzhou University from January 1, 2019 to January 1, 2022 were retrospectively analyzed. The patients were divided into the sivelestat sodium group ( n = 70) and the control group ( n = 71) according to whether they received sivelestat sodium or not. The efficacy indexes included oxygenation index, procalcitonin (PCT), C-reactive protein (CRP), white blood count (WBC), sequential organ failure assessment (SOFA), acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) before and after 7 days of treatment, as well as ventilator supporting time, the length of ICU stay, the length of hospital stay and ICU mortality. The safety indicators included platelet count (PLT) and liver and kidney function. Results:There were no significant differences in age, gender, underlying diseases, infection site, basic drugs, etiology, oxygenation index, biochemical indexes, SOFA and APACHE Ⅱ scores between the two groups. Compared with the control group, the oxygenation index in 7 days was significantly increased [mmHg (1 mmHg ≈ 0.133 kPa): 233.5 (181.0, 278.0) vs. 202.0 (153.0, 243.0), P < 0.01], the levels of PCT, CRP, alanine aminotransferase (ALT) and APACHE Ⅱ score were significantly decreased in the sivelestat sodium group [PCT (μg/L): 0.87 (0.41, 1.61) vs. 1.53 (0.56, 5.33), CRP (mg/L): 64.12 (19.61, 150.86) vs. 107.20 (50.30, 173.00), ALT (U/L): 25.0 (15.0, 43.0) vs. 31.0 (20.0, 65.0), APACHE Ⅱ: 14 (11, 18) vs. 16 (13, 21), all P < 0.05]. However, there were no significant differences in SOFA, WBC, serum creatinine (SCr), PLT, total bilirubin (TBil), aspartate aminotransferase (AST) in 7 days between the sivelestat sodium group and the control group [SOFA: 6.5 (5.0, 10.0) vs. 7.0 (5.0, 10.0), WBC (×10 9/L): 10.5 (8.2, 14.7) vs. 10.5 (7.2, 15.2), SCr (μmol/L): 76.0 (50.0, 124.1) vs. 84.0 (59.0, 129.0), PLT (×10 9/L): 127.5 (59.8, 212.3) vs. 121.0 (55.0, 211.0), TBil (μmol/L): 16.8 (10.0, 32.1) vs. 16.6 (8.4, 26.9), AST (U/L): 31.5 (22.0, 62.3) vs. 37.0 (24.0, 63.0), all P > 0.05]. The ventilator supporting time and the length of ICU stay in the sivelestat sodium group were significantly shorter than those in control group [ventilator supporting time (hours): 147.50 (86.83, 220.00) vs. 182.00 (100.00, 360.00), the length of ICU stay (days): 12.5 (9.0, 18.3) vs. 16.0 (11.0, 23.0), both P < 0.05]. However, there were no significant differences in the length of hospital stay and ICU mortality between the sivelestat sodium group and the control group [the length of hospital stay (days): 20.0 (11.0, 27.3) vs. 13.0 (11.0, 21.0), ICU mortality: 17.1% (12/70) vs. 14.1% (10/71), both P > 0.05]. Conclusions:Sivelestat sodium is safe and effective in patients with sepsis. It can improve the oxygenation index and APACHE Ⅱ score, reduce the levels of PCT and CRP, shorten ventilator supporting time and the length of ICU stay. No adverse reactions such as liver and kidney function injury and platelet abnormality are observed.
RESUMO
OBJECTIVE@#To explore the effect of Xuebijing injection on inflammation in sepsis by regulating intestinal microbiota and its metabolites.@*METHODS@#A total of 45 male Sprague-Dawley (SD) rats were randomly divided into Sham operation group (Sham group), cecal ligation and perforation (CLP) induced sepsis group (CLP group), and Xuebijing intervention group (XBJ group, 4 mL/kg Xuebijing injection was injected intraperitoneally at 1 hour after CLP), with 15 rats in each group. The survival of rats was observed at 24 hours after operation and sacrificed. Feces were collected for 16S rRNA gene sequencing and liquid chromatography-mass spectrometry (LC-MS) analysis.@*RESULTS@#At 24 hours after operation, all rats in the Sham group survived, the mortality of rats in the XBJ group was lower than that in the CLP group [47% (7/15) vs. 60% (9/15), P > 0.05]. Compared with the Sham group, the diversity of gut microbiota in the CLP group decreased, the dominant flora changed, and the abundance of inflammation-related flora increased. Xuebijing improved the changes in gut microbiota caused by sepsis, and α diversity showed an increasing trend (Ace index: 406.0±22.5 vs. 363.2±38.2, Chao1 index: 409.7±21.8 vs. 362.4±42.5, both P > 0.05). Restrictive constrained principal coordinate analysis (cPCoA) showed a high similarity in gut microbiota among the same group of rats. The CLP group was dominated by Bacteroidetes, while the Sham and XBJ groups were dominated by Firmicutes. In addition, compared with the CLP group, Xuebijing treatment increased the abundance of beneficial bacteria in septic rats, such as Verrucomicrobia, Akkermansia and Lactobacillus. LC-MS and orthogonal partial least squares discriminant analysis (OPLS-DA) showed that there were 12 main differential metabolites among the three groups, and there were certain correlations between these metabolites, which were related to amino acid and lipid metabolism. Correlation analysis showed a significant correlation between changes in metabolites and microbial communities.@*CONCLUSIONS@#Xuebijing can improve the survival rate of septic rats, regulate the composition of intestinal flora and related metabolites, which provides a new pathophysiological mechanism for Xuebijing in the treatment of sepsis.

Objectve:To study the effect of gabexate mesylate (GM) on acute lung injury (ALI) in septic rats based on metabonomics.Methods:Fifty-seven SD rats were randomly(random number) divided into three groups: sham operation group (SC group), cecal ligation puncture induced septic ALI group (CLP group), and intraperitoneal administration of GM at 1 h after CLP (CLP-GM group). Twenty-four h after the experiment, the survival of rats in the SC, CLP and CLP-GM groups was observed, the lung tissue was collected for HE staining to observe the pathological changes, and the plasma was collected for metabonomics detection to analyze the characteristics of metabolites.Results:Compared with the SC group, the infiltration of inflammatory cells in the lung tissue of rats in the CLP groupincreased significantly, and the metabolic profile of plasma changed significantly. However, the pathological and metabonomic characteristics of the CLP-GM group showed that the above changes were reversed after the application of GM. Twelve major differential metabolites were found in plasma. The metabolic pathways involved in the disorder included biosynthesis of phenylalanine, tyrosine and tryptophan, phenylalanine metabolism and sphingolipid metabolism.Conclusions:GM may improve septic ALI by regulating amino acid metabolism, sphingolipid metabolism and other metabolic pathways.
RESUMO
Semen Ziziphi spinosae ( SZS) , as a commonly used traditional Chinese medicine in clinic for insomnia therapy, is rich in pharmacological active ingredients such as saponins, flavonoids, alkaloids, oil and the other chemical compounds. The recent stud-ies indicated that some active ingredients in SZS exhibited a variety of activities including sedative hypnotics, antianxiety and anti-de-pression by regulating particular neurotransmitters such as 5-hydroxytryptamine (5-HT), gamma-amino butyric acid (GABA), norepi-nephrine, dopamine and glutamate. In accordance with the previous studies on pharmacological activities of SZS, this paper summa-rized and reviewed the applications of SZS in the treatment of central nervous system diseases, myocardial diseases and hepatic disea-ses, which might provide solid evidence for the application development of SZS.
