Chinese Journal of Nephrology 2013;29(6):423-428
Objective To determine whether triggering receptor expressed on myeloid cells-1 (sTREM-1) and urinary neutrophil gelatinase-associated lipocalin (NGAL) were early biomarkers of acute kidney injury (AKI) secondary to sepsis.Methods A total of 141 eligible patients were enrolled in this prospective study.Blood and urine samples were collected at different time points as soon as sepsis was diagnosed.The concentrations of serum creatinine (Scr),urine sTREM-1 and NGAL were measured.According to AKI criteria,patients were divided into the AKI group and non-AKI group.Dynamic changes of levels of Scr,urine sTREM-1 and NGAL were observed in two groups.The receiver operating characteristic curves were used to evaluate the early diagnostic value of urine sTREM-1 and NGAL.Results Among 141 septic patients,44 (31.2%) cases had concomitant AKI.Twenty four hours after sepsis diagnosed,the level of Scr rose to 1.91 times of the baseline [(140.5±13.6) vs (82.6± 15.3) μmol/L,P < 0.05],which met the diagnostic criteria of AKI.In the AKI group,urinary concentrations of sTREM-1 and NGAL at 8 h after the diagnosis of sepsis began to rise significantly from baseline [(100.5±17.4) vs (38.9± 14.7) ng/L; (144.6±51.9) vs (56.2±43.8) μg/L,both P < 0.05].And at the following time points,urinary concentrations of sTREM-1 and NGAL were significantly higher than the baseline levels and that of the non-AKI group (all P < 0.05).At 8 h time point,thearea under the curve of urine sTREM-1 was 0.877 (95%CI 0.756-0.914),the sensitivity was 89.1% and specificity was 82.0% with a cutoff value of 70 ng/L.At 8 h time point,the area under the curve of urine NGAL was 0.862 (95% CI 0.703-0.958),the sensitivity was 87.4% and specificity was 85.5% with a cutoff value of 90 μg/L.Conclusions Urinary concentrations of sTREM-1 and NGAL at 8 h time point after the diagnosis of sepsis have predictive value for AKI and their diagnostic time is much earlier than that of Scr.Therefore,urinary sTREM-1 and NGAL can be used as early biomarkers of septic AKI.

Objective To observe the influences of valsartan on maintenance of sinus rhythm and left atrial contraction function after cardioversion of permanent atrial fibrillation, and discuss if angiotensin Ⅱ (AT-Ⅱ)receptor blockade could reverse atrial remodeling and remove the basis of permanent atrial fibrillation relapse. Methods Seventy-two patients with permanent atrial fibrillation were divided into control group (36 patients)and valsartan group(36 patients)by random digits table. The two groups were given amiodarone of 200 mg oral once every 8 hours on the eardioversion day. Five days later, the dose was decreased to 200 mg once every 12 hours. And another 5 days later, the dose was again decreased to 200 mg once a day. And 1 month later, the dose was decreased to 100 mg once a day which would be kept for 8 months. On the electrical conversion day and after 8 months, the patients of the two groups were performed echocardiography, and the left atrial dimension(LAD), end diastolic area(EDA), end diastolic volume (EDV), end systolic area(ESA)and end systolic volume(ESV)were compared. Results In 72 patients,59 patients were successful in recovering from sinus rhythm, and duration time was(18±6)h,3 patients were given electrical conversion after 72 h, and 10 patients were directly given electrical conversion and successful. Three patients didn't finish follow-up,and 2 patients died. Sixty-seven patients finished follow-up,among whom 33 patients were in control group and 34 patients were in valsartan group. After followed up for 8 months, 36.4%(12/33)patients recurred in control group, and 17.6%(6/34)patients recurred in valsartan group(P<0.05).The levels of LAD, EDA, ESA, EDV and ESV in valsartan group were significantly decreased(P<0.05 or<0.01), but they showed no significantly difference in control group(P > 0.05). The systolic pressure and diastolic pressure decreased in two groups, but there were no significant difference (P>0.05). Conclusion Valsartan combines with amiodarone is superior to amiodarone in maintaining sinus rhythm and improving left atrial contraction function after cardioversion of permanent atrial fibrillation.

Objective To study the thyroid hormone receptor β(TRβ)gene mutation types and characteristics in children with congenital hypothyroidism(CH)and thyroid dysgenesis(TD)from Shandong Province,and to provide theoretical basis for gene diagnosis and prenatal diagnosis. Methods Sixty cases of TD patients of which genomic DNA were isolated from peripheral blood leukocytes were selected by neonatal screening system in Shandong Province. The exon 6 to 12 of TRβ gene were amplified with 8 pairs of sequence specific primers using PCR and the first generation of sequencing method(Sanger method)to detect mutation. The sequencing results were compared with the TRβ gene reference sequence[National Center for Biotechnology Information(NCBI)Reference Sequence:NC 000003. 12]to see whether there was a mutation. Results Analysis of TRβ in 60 cases of CH patients with TD revealed no mutation was demonstrated in exons 6 - 12,but 2 single nucleotide polymorphism(SNP)( rs 3752874,c. 735C ﹥ T;rs79220627, c. 162G ﹥ A)were detected. Through the analysis,the 2 SNP were all synonymous mutations(Phe→Phe;Ser→Ser), without the change of the amino acids. Conclusions TRβ mutation rate is very low,which may not be the main mutation type in CH patients with TD in Shandong Province.
