Predictive value of miRNA-29a and miRNA-10a-5p for 28-day mortality in patients with sepsis-induced acute kidney injury / 南方医科大学学报

<p><b>OBJECTIVE</b>To investigate the value of miR-29a and miR-10a-5p in predicting 28-day mortality in patients with sepsis-induced acute kidney injury.</p><p><b>METHODS</b>Seventy-four patients with sepsis-induced acute kidney injury (AKI) and 41 patients with sepsis but without AKI (control) were examined for serum levels of miR-29a and miR-10a-5p using RT-PCR. The patients were followed up for 28 days to record their survival. Pearson correlation analysis was used to test the correlations of miR-29a and miR-10a-5p with serum creatinine (Scr), cystatin C (Cys-C), and KIM-1 in patients with AKI. Multivariate logistic regression analysis was used to analyze the correlations of miR-29a, miR-10a-5p, Scr, Cys-C, KIM-1 and other risk factors with the 28-day mortality in patients with sepsis. The predictive value of these indicators for evaluating the prognosis of patients with sepsis was analyzed using ROC curve, and miR-29a combined with miR-10a-5p was assessed for their value in predicting the prognosis of the patients.</p><p><b>RESULT</b>During the follow-up for 28 days, 21 of the 74 (35.53%) AKI patients died. Compared with the survivors, the patients died within 28 days showed significantly increased serum levels of Scr , Cys-C, KIM-1, miR-29a, and miR-10a-5p (P<0.05). Pearson correlation analysis showed that miR-29a and miR-10a-5p were positively correlated with serum Scr, Cys-C, and KIM-1 levels; multivariate regression analysis identified miR-29a and miR-10a-5p as the independent risk factors for mortality in the septic patients. The ROC curve analysis showed that the area under the curve (AUC) of miR-29a and miR-10a-5p was 0.82 (95%CI: 0.71-0.89) and 0.75 (95%CI: 0.64-0.85), and that of Scr, Cys-C and KIM-1 was 0.72 (95%CI: 0.66-0.86) , 0.71 (95% CI: 0.63-0.84) and 0.81 (95% CI: 0.72-0.81), respectively. The AUC of miR-29a combined with miR-10a-5p was significantly greater than that of miR-29a, miR-10a-5p, Scr, Cys-C and KIM-1 alone (P<0.05).</p><p><b>CONCLUSION</b>miR-29a and miR-10a-5p have good predictive value in assessing the 28-day mortality of patients with sepsis.</p>

<p><b>OBJECTIVE</b>To explore seroepidemiological status and vaccine coverage of hepatitis B among drug users in Xi'an.</p><p><b>METHODS</b>545 drug users in the Xi'an Compulsory Detoxification Center were asked to answer questionnaire and provide blood sample (3-5 ml) for test of HBsAg, anti-HBc and anti-HBs from March to June 2013. Totally, 545 subjects were surveyed and tested. All of them effectively completed the survey.</p><p><b>RESULTS</b>The positive rates of HBsAg, anti-HBc and anti-HBs were 29.4% (160/545), 60.0% (327/545) and 56.1% (306/545), respectively. Eighty five subjects (15.6%) were negative for all of the three markers. The prevalence of HBsAg and anti-HBc among injection drug users were 40.0% (94/235) and 65.6% (154/235), which was significantly higher than non- injection drug users' (21.6% (52/241), 58.5% (141/241)) and mixed non-injection and injection drug users ((20.3% (14/69), 46.4% (32/69)) (χ(2) = 23.518 and 9.017, respectively, P < 0.05) . The HBsAg positive rate (30.6% (153/500)) of subjects with more than once per day of drug using within one year was significantly higher than those who used drugs for 2-3 times per week (15.6% (7/45)) (χ(2) = 4.51, P < 0.05). Only 11.7% (64/545) of drug users had a clear history of hepatitis B vaccination. The vaccination rate of subjects (3.5% (5/141)) with primary education or below was significantly lower than those with high school (16.3% (45/276)) (χ(2) = 26.61, P < 0.05).

Recombinant tegumental protein Shistosoma japonicum very lowdensity lipoprotein binding protein as a vaccine candidate against Schistosoma japonicum

A polyhistidine-tagged recombinant tegumental protein Schistosoma japonicum very lowdensity lipoprotein binding protein (SVLBP) from adult Schistosoma japonicum was expressed in Escherichia coli. The affinity purified rSVLBP was used to vaccinate mice. The worm numbers and egg deposition recovered from the livers and veins of the immunized mice were 33.5 percent and 47.6 percent less than that from control mice, respectively (p<0.05). There was also a marked increase in the antibody response in vaccinated mice: the titer of IgG1 and IgG2a, IgG2b in the vaccinated group was significantly higher than that in the controls (>1:6,400 in total IgG). In a comparison of the reactivity of sera from healthy individuals and patients with rSVLBP, recognition patterns against this parasite tegumental antigen varied among different groups of the individuals. Notably, the average titres of anti-rSVLBP antibody in sera from faecal egg-negative individuals was significantly higher than that in sera from the faecal egg-positives, which may be reflect SVLBP-specific protection. These results suggested that the parasite tegumental protein SVLBP was a promising candidate for further investigation as a vaccine antigen for use against Asian schistosomiasis.
