[Abstract]
Objective To explore the effect of Bifidobacterium Triple Viable Capsules combined with ulinastatin on intestinal flora and peripheral blood nucleotide binding oligomerization domain-like receptor 3 (NLRP3), Caspase-1 (Caspase-1) of sepsis patients with mechanical ventilation. Methods A total of 98 patients with sepsis treated by mechanical ventilation in Chongqing Emergency Medical Center from January 2017 to December 2020 were collected retrospectively. They were divided into control group and experimental group according to different treatment methods, with 49 cases in each group. All patients were given routine basic treatment, and patients in the control group were treated with Ulinastatin Injection, with 1.0×105 U intravenous drip each time, three times a day. On the basis of the control group, patients in the experimental group were treated with Bifidobacterium Triple Viable Capsule, orally, 0.42 g each time, twice a day. Both groups were evaluated after seven days of treatment. The curative effect, mechanical ventilation time, symptom improvement time, ICU stay time and hospitalization time of two groups were compared. The bacterial content of intestinal flora (Bifidobacterium, Lactobacillus and Staphylococcus), mucosal barrier function indexes [diamine oxidase (DAO), D-lactic acid, endotoxin (ET)], immune function related indexes (CD3+, CD4+, CD8+, CD4+/CD8+) and peripheral blood NLRP3 and Caspase-1 protein levels were measured before and seven days after treatment. The adverse reactions of the two groups during treatment were observed. Results The total effective rate in the experimental group was 91.84%, which was significantly higher than 75.51% in the control group (P<0.05). The duration of mechanical ventilation, symptom improvement, ICU stay and hospital stay in the experimental group were significantly shorter than those in the control group (P<0.05). There was no significant difference in the contents of intestinal Bifidobacteria, Lactobacillus and Staphylococcus between the two groups before treatment (P>0.05). After seven days of treatment, the contents of intestinal Bifidobacteria and Lactobacillus in the two groups increased significantly (P<0.05), and the content of Staphylococcus decreased significantly (P<0.05). After seven days of treatment, the contents of Bifidobacterium and Lactobacillus in the experimental group were significantly higher than those in the control group, and the contents of Staphylococcus were significantly lower than those in the control group (P<0.05). There was no significant difference in the levels of serum DAO, D-lactic acid and ET between two groups before treatment (P>0.05). After seven days of treatment, the levels of serum DAO, D-lactic acid and ET in the two groups were significantly lower than those before treatment (P<0.05). The levels of serum DAO, D-lactic acid and ET in the experimental group were significantly lower than those in the control group (P<0.05). Before treatment, there was no significant difference in the levels of CD3+, CD4+, CD8+, CD4+/CD8+in peripheral blood of patients in two groups (P>0.05). After seven days of treatment, the levels of CD3+, CD4+, CD4+/CD8+ in peripheral blood of the two groups were significantly higher than those before treatment (P<0.05), and the level of CD8+ was significantly lower than that before treatment (P<0.05). After treatment, the levels of CD3+, CD4+, CD4+/CD8+ in peripheral blood of the experimental group were significantly higher than those in the control group (P<0.05), and CD8+ was significantly lower than those in the control group (P<0.05). There was no significant difference in peripheral blood NLRP3 and Caspase-1 protein levels between the two groups before treatment (P>0.05). After seven days of treatment, the levels of peripheral blood NLRP3 and Caspase-1 protein in two groups were significantly lower than those before treatment (P<0.05). After treatment, the levels of peripheral blood NLRP3 and Caspase-1 protein in the experimental group were significantly lower than those in the control group (P<0.05). There was no significant difference in the total incidence of adverse reactions between two groups (P>0.05). Conclusion Bifidobacterium Triple Viable Capsule combined with ulinastatin is effective in treatment of septic patients with mechanical ventilation. It can effectively shorten the time of mechanical ventilation, symptom improvement, ICU stay and hospital stay, restore the balance of intestinal flora, improve the function of mucosal barrier and immunity, regulate the levels of peripheral blood NLRP3 and Caspase-1, and has high safety.
