To investigate the effect of hydrogen gas inhalation on survival rate and serum high mobility group box 1 (HMGB1) levels in severe septic mice.
Severe sepsis was induced by cecal ligation and puncture (CLP) operation in mice.A total of 248 mice were randomly divided into four groups: sham operation group (sham), sham operation with hydrogen gas inhalation group (sham+H2), severe CLP group (severe CLP) and severe CLP with hydrogen gas inhalation group (severe CLP+H2). Hydrogen gas inhalation was given for 1 h at 1st and 6th h after CLP or sham operation, respectively. The survival rates and serum HMGB1 levels of all groups at different time points were measured.
The 7-d survival rates of severe CLP mice was 0 % (Compared with Sham group, P <0.05), and the serum HMBG1 levels from h2 to h32 after CLP operation were significantly increased in severe CLP mice (Compared with Sham group, P <0.05). Hydrogen gas treatment increased the 7-d survival rate of severe CLP mice to 60 % (Compared with severe sepsis group, P <0.05) and significantly reduced the serum HMGB1 levels at different time points (Compared with severe sepsis group, P <0.05).
Hydrogen gas inhalation can decrease the serum HMGB1 levels and increase the survival rate of rats with severe sepsis.
探讨氢气吸入对严重脓毒症小鼠存活率及血清高迁移率族蛋白B1(HMGB1)水平的影响。
采用盲肠结扎穿孔(CLP)手术诱导小鼠发生严重脓毒症。将248只小鼠随机分为四组:假手术组(sham)、假手术氢气吸入组(sham+H2)、严重CLP组(severe CLP)和严重CLP氢气吸入组(severe CLP+H2)。分别在CLP或假手术后第1小时和第6小时给予氢气吸入1小时。测量所有组在不同时间点的存活率和血清HMGB1水平。
严重CLP小鼠的7天存活率为0%(与假手术组相比,P<0.05),CLP手术后2小时至32小时,严重CLP小鼠血清HMBG1水平显著升高(与假手术组相比,P<0.05)。氢气治疗使严重CLP小鼠的7天存活率提高到60%(与严重脓毒症组相比,P<0.05),并显著降低了不同时间点的血清HMGB1水平(与严重脓毒症组相比,P<0.05)。
氢气吸入可降低严重脓毒症大鼠血清HMGB1水平,提高其存活率。
