ObjectiveTo evaluate the protective effect of Xuebijing injection against renal injury in patients with sepsis, and to explore its possible mechanism.Methods A prospective randomized controlled trial (RCT) was conducted in which 62 severe patients with sepsis and septic shock admitted in Department of Critical Care Medicine of Jiangsu Province Traditional Chinese Medicine Hospital from June 2013 to December 2013 were randomly divided into control group and Xuebijing group, with 31 patients in each group. The patients in both groups received basic treatment for sepsis, and the patients in Xuebijing group were additionally given intravenous injection of Xuebijing 100 mL once a day for 7 days. In both groups, the changes in acute physiology and chronic health evaluationⅡ (APACHEⅡ) score were observed before treatment and 1, 3, 7 days after treatment, and the changes in the levels of interleukins (IL-6, IL-10), prothrombin time (PT), fibrinogen (Fib), activated partial thromboplastin time (APTT), serum creatinine (SCr), and Cystain C (Cys C) were determined before treatment and 1 day and 3 days after treatment.Results There was no statistically significant difference in APACHEⅡ score before treatment between two groups, however, the APACHEⅡ scores were significantly decreased in both groups 3 days and 7 days after treatment compared with those before treatment, and the degree of decrease in Xuebijing group was more obvious 7 days after treatment (13.61±7.62 vs. 16.34±8.70,P< 0.05). Serum concentrations of Cys C, SCr, IL-6, IL-10, PT, APTT, and Fib showed no difference between two groups before treatment (allP> 0.05), while after treatment the degrees of improvement of above indexes in Xuebijing group were obviously superior to those in control group, especially 3 days after treatment[Cys C (mg/L):1.12±0.11 vs. 1.35±0.14, SCr (μmol/L): 115.0±31.0 vs. 135.0±24.0, IL-6 (ng/L): 54.27±28.79 vs. 73.35±31.01,PT (s): 13.50±0.11 vs. 15.71±0.11, APTT (s): 43.66±0.31 vs. 48.03±0.55, Fib (g/L): 1.91±0.51 vs. 1.51±0.52, P< 0.05 orP< 0.01].ConclusionXuebijing injection has certain renal protective effect in patients with sepsis, and its mechanism is possibly related to the regulation and improvement of uncontrolled inflammatory response and coagulation function in sepsis.

Objective To investigate the effects of sevoflurane pretreatment on renal ischemia-reperfusion (I/R)-induced apoptosis in kidney in rats. Methods Thirty pathogen-free male SD rats weighing 220-260 g were randomized into 3 groups (n=10 each):group control (group C);group I/R and group sevoflurane(group S). Renal I/R was induced by clamping the left renal pedicle for 45 min in I/R and S groups. In group S inhalation of 2.2% sevoflurane in O2 was started at 30 min before operation and maintained throughout the experiment.Venous blood samples were taken at 3 h of reperfusion for determination of serum BUN and Cr concentrations. The animals were then sacrificed and the left kidneys were removed for microscopic examination, detection of apoptosis(by TUNEL)and determination of heme oxygenase-1(HO-1) mRNA and protein expression (by RT-PCR and Western blot).Results Renal I/R significantly increased serum BUN and Cr concentrations, apoptotic index(percentage of apoptotic cells) and the severity of necrosis of renal proximal convoluted tubules (0=normal,4=necrosis of whole segment of proximal convoluted tubules).Sevoflurane inhalation attenuated the I/R-induced changes mentioned above.HO-1 mRNA and protein expression was up-regulated by I/R and HO-1 mRNA expression was further up-regulated by sevoflurane inhalation.Conclusion Sevoflurane pretreatment can protect kidney against I/R injury by attenuating cell apoptosis.Up-regulation of HO-1 mRNA expression may be involved in the mechanism.
