[Effectiveness of Xuebijing in treatment of multiple organ dysfunction syndrome: a Meta analysis]

To systematical evaluate the effect of Xuebijing injection in the treatment of multiple organ dysfunction syndrome (MODS).

With the keywords including Xuebijing, multiple organ dysfunction syndrome, multiple organ dysfunction and multiple organ failure, PubMed, the Cochrane Library, Embase, China National Knowledge Infrastructure (CNKI), China Biology Medicine (CBM), VIP and Wanfang Data from the database start until March 4th, 2018 were searched for relevant randomized controlled trials (RCTs) related to Xuebijing injection combined conventional treatment versus conventional treatment alone for MODS. The control group received conventional western medicine treatment, including etiological treatment, antibiotics, mechanical ventilation, nutritional support, and comprehensive treatment to maintain fluid, electrolyte, acid and alkali balance. The experimental group was given traditional western medicine combined with Xuebijing injection. The observation parameters included 7-day and 28-day mortality, acute physiology and chronic health evaluation II (APACHE II) and Marshall score, interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), the number of platelets, activated partial thromboplastin time (APTT) and prothrombin time (PT). According to the inclusion and exclusion criteria, two evaluators independently screened the literature, extracted data and evaluated the methodological quality of the included studies. RevMan 5.3 software was used for Meta analysis. Funnel plot was used to analyze publication bias.

A total of 35 RCTs and 2 131 patients were enrolled, including 1 076 in the experimental group and 1 055 in the control group. The results of Meta analysis showed that compared with control group, Xuebijing combined conventional treatment was in favor to decrease the mortality of patients with MODS [7-day mortality: odds ratio (OR) = 0.42, 99% confidence interval (99%CI) = 0.26-0.69, P < 0.000 01; 28-day mortality: OR = 0.31, 99%CI = 0.21-0.45, P < 0.000 01], also could obviously reduce critical condition degree of APACHE II score and the organ function of Marshall score [APACHE II: mean difference (MD) = 3.24, 99%CI = 2.00-4.49, P < 0.000 01; Marshall score: MD = 1.95, 99%CI = 0.50-3.40, P = 0.000 5]. Meanwhile, the results of conventional western medicine combined with Xuebijing in the removal of IL-6 and TNF-α, platelets increase and improvement of PT were better than those of conventional western medicine (IL-6: MD = 5.56, 99%CI = 1.44-9.68, P = 0.000 5; TNF-α: MD = 4.97, 99%CI = 3.44-6.50, P < 0.000 01; platelets: MD = -50.79, 99%CI = -74.84 to -26.74, P < 0.000 1; PT: MD = 4.55, 99%CI = 3.96-5.14, P < 0.000 01), however, there was no obvious advantage in improving APTT (MD = 0.96, 99%CI = -5.08-7.00, P = 0.68). The analysis of funnel map showed that the effect points of various studies were mainly centered on the amount of combined effect, and the "inverted funnel" type was generally symmetrical distribution. However, because the number of the included studies was less, the literature bias could not be completely eliminated.

Xuebijing injection may through its strong cytokines clearance, platelet increase and blood coagulation improvement to protect the organ function in patients with MODS, so as to reduce the mortality and improve the prognosis.
