OBJECTIVE To study the influence of focused ultrasound on the morphology of nasal mucosa in sheep. METHODS A model CZB ultrasound therapeutic system for rhinitis, developed and produced by Chongqing Haifu(HIFU)Technology Co.,Ltd.,Chongqing China,was used in this study. Linear scans were performed on bovine liver in vitro under different scan parameters, and the biologic focal field(BFF)was detected to evaluate if it met the requirements of designed. The nasal mucosa of inferior turbinate of sheep was exposed with the same scan parameters under the observation of nasal endoscope, and morphological changes of the nasal mucosa were observed by gross examination, light and electron microscopes. RESULTS This study revealed that the designed biological focal field in bovine liver in vitro could be obtained under the scan parameters mentioned above. Linear scan with the same condition,there was no obvious change in appearance and color of the treated nasal mucosa in the inferior turbinate of the sheep. However,3 days after treatment,there was an increased secretion in the nasal cavity,which recovered 7 days post-treatment. Light microscopic examination 3 days after exposure showed that the epithelia of the nasal mucosa was intact and there was diffused distribution of spot coagulated necroses in the subepithelia layer of treated nasal mucosa. Degeneration of vascular endothelial cells and thrombosis of blood vessels were found in the coagulated necrosis region. Besides,degeneration or necrosis of nerve cells was induced,and glandular cells werepartially or completely damaged. The structure of epithelial goblet cells and ciliated cells in the treated nasal mucosa appeared to be normal under the observation of electronic microscope. At the seventh day after treatment,signs of tissue regeneration such as hyperplasia of collagen fiber were found in the coagulated region,and the necrosis tissue began to dissolve and was absorbed at the 14th day post-treatment. CONCLUSION Under the above scan parameters,the energy of focused ultrasound could be deposited specifically at the subepithelia layer,and to ablate the targeted nasal mucous tissues which are rich in blood vessels,nerves and glands. There were no damage to the non-target area such as epithelial layer,which could maintain the normal structure and biological function of mucociliary of nasal mucosa.

OBJECTIVETo compare the heart rate variability (HRV) measurements between ballistocardiogram (BCG) and electrocardiography (ECG).
METHODSThe signals of BCG and ECG of 21 patients were collected synchronously. JJ intervals of BCG and RR intervals of ECG were used to calculate the cardiac periods. The parameters of HRV analysis were calculated in time domain analysis, frequency domain analysis and nonlinear analysis. The results derived from BCG and ECG were compared.
RESULTSThe parameters of HRV analysis calculated from BCG and ECG had high similarity. The correlation coefficients of SDNN, TP, LF, HF and SD2 between the BCG and ECG methods were high (r = 1). The correlation coefficients of rMSSD and SD2 were 0.99 and of PNN50 and LF/HF were 0.98 between the two methods. HRV analysis results derived from the two methods were similar (P > 0.05).
CONCLUSIONHRV could also be measured reliably by calculating the JJ interval from BCG.

OBJECTIVETo find out and analyze differentially expressed miRNAs in the plasma of benzene exposed workers, and explore the potential roles of plasma miRNAs in the development of hematologic toxicity induced by benzene exposure.
METHODSBy individual matching, low blood cell group, unstable blood cell group and normal group of 10 benzene exposed workers in each group were taken as subjects. Microarray was used to find out differentially expressed miRNAs among three groups. Three miRNAs validated by real-time quantitative PCR. Target genes of 9 miRNAs with the high abundance and significant difference were predicted using Target scan, Picture and miRanda softwares. David 6.7 online platform was used to perform GO term enrichment and KEGG pathway analysis of those targets.
RESULTSMicroarray screened out that 138 miRNAs were differentially expressed. Three significant classes of differentially expressed miRNAs were found with the cluster analysis. The detected expressions of miR-638, let-7f-5p and miR-223-3p by relative RT-qPCR was consistent with the microarray date. Pathway analysis showed that the most enriched pathway was focal adhesion, with 6 potential functional targets, including SOS₂, VCL, CCND2, COL4A6, IGF1 and MAPK1.
CONCLUSIONWe have identified the plasma miRNA profile in benzene exposed workers, and further analysis indicates that focal adhesion-associated miRNAs play a potential role in hematologic toxicity induced by benzene exposure.
