Effect of an Herbal-Based Injection on 28-Day Mortality in Patients With Sepsis: The EXIT-SEP Randomized Clinical Trial.

Importance: Previous research has suggested that Xuebijing injection (XBJ), an herbal-based intravenous preparation, may reduce mortality among patients with sepsis. Objective: To determine the effect of XBJ vs placebo on 28-day mortality among patients with sepsis. Design, Setting, and Participants: The Efficacy of Xuebijing Injection in Patients With Sepsis (EXIT-SEP) trial was a multicenter, randomized double-blind, placebo-controlled trial conducted in intensive care units at 45 sites and included 1817 randomized patients with sepsis (sepsis 3.0) present for less than 48 hours. Patients aged 18 to 75 years with a Sequential Organ Failure Assessment score of 2 to 13 were enrolled. The study was conducted from October 2017 to June 2019. The final date of follow-up was July 26, 2019. Data analysis was performed from January 2020 to August 2022. Interventions: The patients were randomized to receive either intravenous infusion of XBJ (100 mL, n = 911) or volume-matched saline placebo (n = 906) every 12 hours for 5 days. Main Outcomes and Measures: The primary outcome was 28-day mortality. Results: Among the 1817 patients who were randomized (mean [SD] age, 56.5 [13.5] years; 1199 [66.0%] men), 1760 (96.9%) completed the trial. In these patients, the 28-day mortality rate was significantly different between the placebo group and the XBJ group (230 of 882 patients [26.1%] vs 165 of 878 patients [18.8%], respectively; P < .001). The absolute risk difference was 7.3 (95% CI, 3.4-11.2) percentage points. The incidence of adverse events was 222 of 878 patients (25.3%) in the placebo group and 200 of 872 patients (22.9%) in the XBJ group. Conclusions and Relevance: In this randomized clinical trial among patients with sepsis, the administration of XBJ reduced 28-day mortality compared with placebo. Trial Registration: ClinicalTrials.gov Identifier: NCT03238742.

XueBiJing Injection Versus Placebo for Critically Ill Patients With Severe Community-Acquired Pneumonia: A Randomized Controlled Trial.

OBJECTIVES: To investigate whether XueBiJing injection improves clinical outcomes in critically ill patients with severe community-acquired pneumonia. DESIGN: Prospective, randomized, controlled study. SETTING: Thirty-three hospitals in China. PATIENTS: A total of 710 adults 18-75 years old with severe community-acquired pneumonia. INTERVENTIONS: Participants in the XueBiJing group received XueBiJing, 100 mL, q12 hours, and the control group received a visually indistinguishable placebo. MEASUREMENTS AND MAIN RESULTS: The primary outcome was 8-day improvement in the pneumonia severity index risk rating. Secondary outcomes were 28-day mortality rate, duration of mechanical ventilation and total duration of ICU stay. Improvement in the pneumonia severity index risk rating, from a previously defined endpoint, occurred in 203 (60.78%) participants receiving XueBiJing and in 158 (46.33%) participants receiving placebo (between-group difference [95% CI], 14.4% [6.9-21.8%]; p < 0.001). Fifty-three (15.87%) XueBiJing recipients and 84 (24.63%) placebo recipients (8.8% [2.4-15.2%]; p = 0.006) died within 28 days. XueBiJing administration also decreased the mechanical ventilation time and the total ICU stay duration. The median mechanical ventilation time was 11.0 versus 16.5 days for the XueBiJing and placebo groups, respectively (p = 0.012). The total duration of ICU stay was 12 days for XueBiJing recipients versus 16 days for placebo recipients (p = 0.004). A total of 256 patients experienced adverse events (119 [35.63%] vs 137 [40.18%] in the XueBiJing and placebo groups, respectively [p = 0.235]). CONCLUSIONS: In critically ill patients with severe community-acquired pneumonia, XueBiJing injection led to a statistically significant improvement in the primary endpoint of the pneumonia severity index as well a significant improvement in the secondary clinical outcomes of mortality, duration of mechanical ventilation and duration of ICU stay.

Growth inhibition and apoptosis induction in human hepatoma cells by tanshinone II A.

In order to study the effect of tanshinone II A on growth and apoptosis in human hepatoma cell line BEL-7402 in vitro, the human hepatoma cell line BEL-7402 was treated with tanshinone II A at various concentrations for 72 h. Growth suppression was evaluated by MTT assay; apoptosis-related alterations in morphology and biochemistry were ascertained under cytochemical staining (Hoechst 33258), transmission electron microscopy (TEM), and DNA agarose gel electrophoresis. Apoptotic rate was quantified by flow cytometry (FCM). The results showed that Tanshinone II A could inhibit the growth of hepatoma cells in a dose-dependent manner, with IC50 value being 6.28 micrograms/ml. After treatment with 1-10 micrograms/ml tanshinone II A for 72 h, BEL-7402 cells apoptosis with nuclear chromatin condensation and fragmentation as well as cell shrinkage and the formation of apoptotic bodies were observed. DNA ladder could be demonstrated on DNA electrophoresis. FCM analysis showed hypodiploid peaks on histogram, and the apoptotic rates at 5 micrograms/ml concentration for 12 h, 24 h, 36 h, 48 h and 72 h were (2.32 +/- 0.16)%, (3.01 +/- 0.35)%, (3.87 +/- 0.43)%, (6.73 +/- 0.58)% and (20.85 +/- 1.74)% respectively, which were all significantly higher than those in the control group (1.07 +/- 0.13)%. It is concluded that Tanshinone II A could induce human hepatoma cell line BEL-7402 apoptosis, which may be related to the mechanism of growth inhibition.
