Objective To explore the value of serum microRNA-155-5p and -133a-3p (miR-155-5p and miR-133a-3p) expression for the diagnosis and prognosis evaluation of sepsis. Methods A prospective observational study was conducted. 105 sepsis patients admitted to emergency intensive care unit (EICU) of the First Affiliated Hospital of Zhengzhou University from January 2015 to January 2016 were enrolled. They were divided into three groups according to the severity: 35 patients with sepsis, 35 with severe sepsis, and 35 with septic shock. At the same time, 35 healthy persons were selected as the control group. According to the prognosis, the patients were divided into improved group (n = 70) and in-hospital death group (n = 35). The clinical data of all the subjects were collected. The mRNA expressions of miR-155-5p and miR-133a-3p were determined by reverse transcription-polymerase chain reaction (RT-PCR). The receiver-operating characteristic curve (ROC) was plotted to evaluate their clinical value for the diagnosis and prognosis of sepsis. The binary logistic regression was used to analyze the risk factors affecting the prognosis of sepsis patients. Results ① The mRNA expressions of serum miR-155-5p and miR-133a-3p were gradually increased with the aggravation of sepsis. The mRNA expression of miR-155-5p (2-ΔCt) in sepsis, severe sepsis, sepsis shock groups was 1.89±0.48, 2.21±0.41, 2.79±0.73 (F = 23.737, P = 0.000), and the mRNA expression of miR-133a-3p (2-ΔCt) was 1.38±0.31, 1.74±0.65, 2.08±0.47, respectively (F = 27.710, P = 0.000). It was shown by ROC curve analysis that the area under the ROC curve (AUC) of serum miR-155-5p and miR-133a-3p for the diagnosis of sepsis was 0.855 [95% confidence interval (95%CI) = 0.761-0.949] and 0.769 (95%CI = 0.666-0.872) respectively. The cut-off value of miR-155-5p for the diagnosis of sepsis was 1.64, the sensitivity was 85.3%, and specificity was 80.6%. While the cut-off value of miR-133a-3p was 0.82, the sensitivity and specificity were 97.9% and 54.8% respectively. ② Compared with improved group, the patients of in-hospital death group were more serious, and procalcitonin (PCT), C-reactive protein (CRP), D-dimer, lactic acid (Lac), sequential organ failure assessment (SOFA) score, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score, and the mRNA expressions of miR-155-5p and miR-133a-3p were significantly increased (all P < 0.05). While there was no statistically significant difference in gender, age, white blood cells (WBC), serum creatinine (SCr) between the two groups (all P > 0.05). It was shown by binary logistic regression analysis that Lac [odds ratio (OR) = 0.514, 95%CI = 0.260-0.893, P = 0.024], sepsis severity (OR = 0.039, 95%CI = 0.023-2.955, P = 0.016), SOFA score (OR = 0.668, 95%CI = 0.474-0.825, P = 0.001), serum miR-155-5p expression (OR = 0.117, 95%CI = 0.020-0.530, P = 0.007) were the risk factors affecting the prognosis of patients with sepsis. Conclusions The expression of serum miR-155-5p and miR-133a-3p may be used as specific indicators for the diagnosis of sepsis. And the expression of miR-155-5p can be used as independent impact factor for the estimation of sepsis prognosis.

Objective: To evaluate the therapeutic efficacy of acupuncture plus Dang Gui Bu Xue Qu Feng Tang for benign essential blepharospasm (BEB). Methods: A prospective randomized controlled trial was performed. A total of 105 participants were randomized 1:1:1 into an acupuncture group, a herbal medicine group and an acupuncture plus herbal medicine group. Participants in the acupuncture group received manual acupuncture treatment, twice a week. Participants in the herbal medicine group received Dang Gui Bu Xue Qu Feng Tang, oral administration, once a day. Participants in the acupuncture plus herbal medicine group received both treatments. The therapeutic effects of the three groups were evaluated after four weeks of treatment. The primary outcome was the Jankovic rating scale (JRS) score, and the secondary outcome was the blepharospasm disability index (BSDI) score. Results: After four weeks of treatment, the JRS total scores significantly decreased in all three groups versus baseline (P<0.05). A greater reduction in the JRS total score was reported in participants in the acupuncture plus herbal medicine group (P<0.05), but there was no significant difference between the acupuncture group and the herbal medicine group (P>0.05). The acupuncture plus herbal medicine group had a greater decrease in the JRS severity score than the herbal medicine group (P<0.05). The reduction in the JRS frequency score was not significantly different among the three groups (P>0.05). The BSDI scores significantly decreased in all three groups versus baseline (P<0.05), but the reduction in the BSDI score was insignificantly different among the three groups (P>0.05). Conclusion: It is effective in the treatment of BEB either to use acupuncture and Dang Gui Bu Xue Qu Feng Tang alone or in combination. The combination therapy shows a more significant effect than either of the treatment alone.
