Purpose To study the hemodynamic changes of kidney interlobar artery in children with type 1 diabetes, and to explore the clinical value of the color Doppler ultrasound in diabetic nephropathy during the incubation period. Materials and Methods The study was performed in 52 children with type 1 diabetes and in 51 age-matched healthy children as control group. The resistance index (RI) of interlobar artery was measured with color Doppler ultrasonography, and the clinical data and laboratory indicators were analyzed. Results The left kidney RI, right kidney RI and average RI were all significantly higher in children with diabetes than in age-matched healthy group (P<0.01). The mean RI were correlated positively with (HbA1c) (r=0.96, P<0.01) and diabetes duration (r=0.31, P<0.01), respectively. Fasting blood glucose, glycated hemoglobin, and glomerular filtration rate were significantly higher in children with diabetes than in age-matched healthy group (P<0.01). Conclusion The RI of interlobar artery increases in children with type 1 diabetes. Early changes of renal hemodynamics in children with type 1 diabetes are detectable with Doppler sonography, and have certain value in early diagnosis of diabetic nephropathy.

OBJECTIVETo summarize the ultrasonography features of neonate corpus callosum agenesis for better diagnosis of this condition.

METHODSA total of 8563 neonates were screened by cerebral ultrasound in neonate care unit of our hospital from June 2010 to December 2012, and 37 cases of agenesis of the corpus callosum were identified. The diagnostic accuracy of ultrasonography and magnetic resonance imaging (MRI) for this condition was evaluated.

RESULTSThe sensitivity, specificity, and accuracy of ultrasound diagnosis for complete and incomplete absence of neonate corpus callosum were 100% and 90%, 90.9% and 94.1%, 94.6% and 91.9% in the 37 cases, respectively. The Kappa value of ultrasonography and MRI were 0.890 and 0.837, with a consistent rate of 91%.

CONCLUSIONUltrasonography and MRI show a high consistency in the diagnosis of neonatal agenesis of the corpus callosum.

Objective To understand the infected strains and prevalence of brucellosis in occupational population in Tacheng and Kashgar regions,Xinjiang Uygur Autonomous Region.Methods In September 2015,blood samples from occupational population (including herders,semi-agricultural and semi-pastoral,veterinarians) and non-occupational population (including students and cadres) were collected to detect Brucellaspecific antibody and bacterial nucleic acids by rose bengal plate test (RBPT),serological standard tube agglutination test (SAT) and PCR methods,respectively.The positive products of PCR were sent to Shanghai Sangon Biotechnology Co.,LTD.Then the sequence results were retrieved online using the basic alignment search tool (BLAST) in GenBank web page and uploaded to NCBI (National Center for Biotechnology Information).Results A total of 546 blood samples were tested,including 300 males,aged (55-± 15) years old,and 246 females,aged (54 ± 12) years old.The positive rates were 17.58％ (96/546) and 6.78％ (37/546) in 546 blood samples by serological method and genetic markers targeting omp22 and omp2,respectively.The positive rates were statistically significant (x2 =29.8,P ＜ 0.05).Additionally,based on BLAST analysis of outer membrane protein omp22 and omp2 genes,the positive products were identified as Brucella abortus,and the sequence similarity was 100.00％ (253/253,863/863 bp) to Brucella abortus strain Wisconsin genome assembly,chromosome (LT651712).Conclusions Brucellosis has a high infection rate in the occupational population of some animal husbandry-based groups in Xinjiang.The infection strain is abortive species Brucella,and health education for the occupational population and prevention of brucellosis should be strengthened to reduce the infection rate.

Objective To investigate the expression levels and clinical significance of differentially expressed microRNAs(miRNAs)based on high-throughput sequencing in patients with left ventricular hypertrophy(LVH)and their possible regulatory mechanisms.Methods The miRNA sequencing was performed on plasma samples from 4 LVH patients and 4 healthy volunteers,and qRT-PCR validation was performed on plasma samples from 25 healthy volunteers and 35 LVH patients.The target genes of the obtained differentially expressed miRNA were predicted.The molecular function(MF),biological process(BP)and cellular components(CC)of these miRNAs were predicted by the Gene Ontology(GO)enrichment analysis,and their signal pathways were predicted by the Kyoto Encyclopedia of Genes and Genomes analysis.Meanwhile,the protein-protein interaction network was constructed.The diagnostic values of 2 differentially expressed miRNAs(hsa-miR-942-5p and hsa-miR-184)in LVH were analyzed by the area under the receiver operating characteristic(ROC)curve(AUCROC).Results A total of 945 differentially expressed miRNAs were identified,of which 1 and 9 were observed to be significantly upregulated and downregulated,respectively.The expression levels of hsa-miR-942-5p and hsa-miR-184 were verified by qRT-PCR to be significantly downregulated.The AUCROC of hsa-miR-942-5p and hsa-miR-184 were 0.694 6 and 0.880 4,respectively.Bioinformatics analysis revealed that the target genes were mainly enriched in the cell senescence,sphingolipid metabolism,and TGF-β,p53,and diabetic metabolism related signaling pathways.Conclusion The expression levels of hsa-miR-942-5p and hsa-miR-184 in plasma of LVH patients are significantly decreased,suggesting that they have good diagnostic potential.
