Abstract
Objective: To investigate the snoring status of school-aged children in Beijing and explore the association of snoring and academic performance. Methods: A total of 7 925 children aged from 6 to 14 were selected from 15 primary and middle schools at 7 districts (Xicheng, Chaoyang, Changping, Shunyi, Fangshan, Huairou and Mentougou) in Beijing in 2015, using multi-stage stratified cluster random sampling method. The recruited children were asked to complete the Pediatric Sleep Questionnaire (PSQ) and a questionnaire related to sleep behavior. The multiplelogistic regression was used to analyze the association of snoring and academic performance. Results: A total of 794 (12.44%) children showed a decline in academic performance among 6 383 eligible respondentsfor data analysis. 580 (9.08%) children with snoring was identified, of which 333 and 247 were in frequency of 1-2 times per week and frequency of ≥3 times per week, respectively; 357, 170 and 53 were in snoring grade Ⅰ, grade Ⅱ and grade Ⅲ, respectively. Compared with the children without snoring, the OR (95%CI) for children with 1-2 times per week and ≥3 times per week was 1.363 (1.000-1.857) and 1.605 (1.135-2.269), respectively; and the OR (95%CI) for children with grade Ⅰ, grade Ⅱ and grade Ⅲ of snoring was 1.226 (0.893-1.683), 1.595 (1.062-2.397) and 2.31 (1.17-4.565), respectively. Conclusion: There is a statistical relationship between snoring and the decline of academic performance. The decline of academic performance positively associated with increased frequency and grade of snoring.

Abstract
Objective: To investigate the relationship between the expression of macrophage migration inhibitory factor (MIF) gene and the incidence of gestational diabetes mellitus (GDM) in Chinese Han population in northern China. Method: This study was consisted of 126 GDM women and 150 cases of healthy subjects who came from the obstetrics department of Maternity Hospital of Qingdao University and Maternity and Child Care Hospital of Donggang District of Rizhao. The protein expression of MIF in placenta tissue was detected by Western blot method. The blood glucose, insulin levels and other clinical physicochemical index were tested. The differences of MIF, fasting blood-glucose (FBG), fasting insulin (FIN) and the homeostasis model assessment of insulin resistance (HOMA-IR) were compared between the two groups of pregnant women. Result: The level of MIF protein in GDM group (0.85±0.10) was higher than that in healthy pregnant group (0.12±0.09), with significant difference (P<0.001). Insulin resistance index in GDM group were higher than that in healthy pregnant group, with significant difference (P<0.001). Conclusion: The expression of MIF in placental tissues of GDM women was increased and correlated with insulin resistance in GDM patients, suggesting that MIF may play an important role in the occurrence and development of GDM.

Abstract
BACKGROUND It is inappropriate to select insertion sequence (IS) 6110 as the amplification target for the quantitative analysis of Mycobacterium tuberculosis complex (MTC). OBJECTIVE To develop a novel Taqman real-time polymerase chain reaction (RT-PCR) for the quantitative analysis of MTC by amplifying a single-copy PCR target. DESIGN Analytic sensitivity and specificity, repeatability and reproducibility, and standard curve were estimated by analysing 18 reference strains and 100 clinical isolates. Diagnostic sensitivity and specificity, positive predictive value (PPV) and negative predictive value (NPV) were evaluated by detecting 50 clinical specimens. Quantitative accuracies of commercial and in-house Taqman RT-PCR were also compared. RESULTS Analytic sensitivity of this method was 30 colony-forming units/ml and analytic specificity was 100%. In comparison with commercial Taqman RT-PCR (reference), diagnostic sensitivity, diagnostic specificity, PPV and NPV of the novel Taqman RT-PCR were respectively 85.7%, 94.4%, 85.7% and 94.4%. There was no significant difference between the two methods (χ(2) = 0.25, P > 0.05) and there was strong agreement between them (κ = 0.802, P < 0.05). In-house Taqman RT-PCR was more accurate than commercial assay. CONCLUSIONS The novel RT-PCR is sensitive and specific for the detection of MTC and it is also accurate for quantitative analysis of MTC.

Abstract
A multivariate calibration approach, using partial least squares regression, has been developed for measurement of aerosol elemental concentration. A training set consisting of 25 orthogonal aerosol samples with 9 factors (elements: Cr, Mn, Fe, Ni, Cu, Zn, Cd, Pb, Ti) and 5 levels (elemental concentrations) was designed. Spectral information was obtained for each aerosol sample using aerosol spark emission spectroscopy (ASES) at a time resolution of 1 minute. Simultaneous filter samples were collected for determination of elemental concentration using an inductively coupled plasma mass spectrometry (ICP-MS) analysis. Two regression models, PLS1 and PLS2, were developed to predict mass concentration from spectral measurements. Prediction ability of the models improved substantially when only signature wavelengths were included instead of the entire spectrum. The PLS1 model with 45 selected spectral variables (PLS1-45 model) presented the lowest relative root mean square error of cross validation (RMSECV; 16 - 35%). The detection limits using the PLS1-45 model, for the nine elements were in the range of 0.16 - 0.50 μg/m3. The performance of both multivariate and univariate regression models were tested for an unknown sample of welding fume aerosol. The multivariate model did not provide significantly better prediction compared to the univariate model. In spite of the difference in matrices of calibration aerosol and the unknown test aerosol, the results from PLS model show good agreement with those from filter measurements. The relative root mean square error of prediction (RMSEP) obtained from PLS1-45 model was 13% for Cr, 23% for Fe, 22% for Mn and 12% for Ni. The study shows that in spite of lower spectral resolution and lack of sample preparation, reliable and robust measurements can be obtained using the proposed calibration method based on PLS regression.

Abstract
Nitrogen doped hierarchical activated carbons with high surface areas and different pore structures are prepared form polyacrylonitrile fibers through KOH activation by two steps. It is found that the specific surface area and porosity of the activated carbons depend strongly on the activation temperatures. The specific surface area increases from 607 m2 g−1 to 3797 m2 g−1 when the activation temperature increases from 600 °C to 800 °C, and then decreases to 3379 m2 g−1 at 900 °C. It shows that the hierarchical activated carbon prepared at a moderate activation temperature of 700 °C exhibits the largest CO2 capture amount, i.e., 5.25 and 3.63 mmol g−1 at 273 and 298 K, respectively, under the pressure of 1 bar. The excellent CO2 capture properties are due to the high specific surface area of 2146 m2 g−1 and high nitrogen content (5.2 wt%) of the obtained sample. On the other hand, when used as supercapacitor electrodes, the sample with the activation temperature at 800 °C shows the largest specific capacitance of 302 F g−1 at a current density of 1 A g−1 in 6 M KOH aqueous electrolyte, with an excellent rate capability of 231 F g−1 at 10 A g−1. Furthermore, a nearly linear relationship between nitrogen content in the nitrogen doped activated carbons and specific CO2 uptake as well as the specific capacitance were first established, indicating nitrogen doping was playing key roles in improving CO2 adsorption and supercapacitor performance. The experimental results indicate that the thus obtained nitrogen doped hierarchical activated carbons are very promising for reducing CO2 green house gas by adsorption as well as storing energy as utilized in supercapacitors. Nitrogen doped activated carbons with high surface area up to 3797 m2 g−1 exhibit specific capacitance of 231 F g−1 at a current density of 10 A g−1.![]()

Abstract
Objective: To investigate the prognostic factors of primary liver cancer treated with transcatheter arterial chemoembolization (TACE) combined with radiofrequency ablation (RFA), and then to establish a prognostic model. Methods: Clinicopathological and follow-up data of 145 patients who underwent TACE combined with RFA from January 2010 to December 2012 were retrospectively analyzed. Univariate and multivariate survival analyses were performed using the Cox proportional hazards model, and the prognostic model was established. Results: The 1, 2, and 3-year survival rates were 92.6%, 81.4% and 66.2%, respectively. The 3-year recurrence and metastasis rate was 64.8%.Multivariate analysis showed that female cases and higher serum albumin levels were the protective factors for the 3-year overall and relapse-free survival of patients(P<0.05 for all). High levels of alpha-fetoprotein (AFP), alanine aminotransferase (ALT), total bilirubin (TBIL), portal vein thrombosis and higher Child Pugh stages were the independent risk factors for the 3-year overall survival(P<0.05 for all). High levels of AFP, TBIL, portal vein thrombosis and advanced stages of BCLC staging (B and C) were the independent risk factors for tumor recurrence and metastasis(P<0.05 for all). The predictive model established based on the multivariate analysis showed good sensitivity and specificity. The area under ROC curve were higher than 0.90. Conclusions: The prognosis of liver cancer patients treated with TACE combined with RFA is affected by various clinicopathological factors. The systematic evaluation of the relevant factors before treatment may help to select proper patients and improve prognosis.

Abstract
This study evaluated the effects of Bacillus fermentation on soybean meal protein (SBMP) microstructure and major anti-nutritional factors (ANFs) in soybean meal (SBM). The Bacillus siamensis isolate JL8 producing high yield of protease at 519·1 U g-1 was selected for the laboratory production of fermented soybean meal (FSBM). After 24 h fermentation, the FSBM showed better properties compared with those of SBM, the ANFs such as glycinin, β-conglycinin and trypsin inhibitor significantly decreased by 86·0, 70·3 and 95·01%, while in vitro digestibility and absorbability increased by 8·7 and 18·9% respectively. Scanning electron microscopy (SEM) image of fermented soybean meal protein showed smaller aggregates and looser network than that of SBMP. Secondary structure examination of proteins revealed fermentation significantly decreased the content of β-sheet structure by 43·2% and increased the random coil structure by 59·9%. It is demonstrated that Bacillus fermentation improved the nutritional quality of SBM through degrading ANFs and changing the microstructure of SBMP. SIGNIFICANCE AND IMPACT OF THE STUDY There is limited information about the structural property changes of soybean protein during fermentation. In this study, physicochemical analysis of soybean meal protein showed evidence that the increase in in vitro digestibility and absorbability of fermented soybean meal reflected the decrease in β-conformation and destruction of original structure in soybean meal protein. The results directly gained the understanding of nutritional quality improvement of soybean meal by Bacillus fermentation, and supply the potential use of Bacillus siamensis for fermented soybean meal production.

Abstract
Lineage-committed differentiation is an essential biological program during odontogenesis, which is tightly regulated by lineage-specific genes. Some of these genes are modified by colocalization of H3K4me3 and H3K27me3 marks at promoter regions in progenitors. These modifications, named "bivalent domains," maintain genes in a poised state and then resolve for later activation or repression during differentiation. Wnt5a has been reported to promote odontogenic differentiation in dental mesenchyme. However, relatively little is known about the epigenetic modulations on Wnt5a activation during tooth development. Here, we investigated the spatiotemporal patterns of H3K4me3 and H3K27me3 marks in developing mouse molars. Associated H3K4me3 methylases (mixed-lineage leukemia [MLL] complex) and H3K27me3 demethylases (JMJD3 and UTX) were dynamically expressed between early and late bell stage of human tooth germs and in cultured human dental papilla cells (hDPCs) during odontogenic induction. Poised WNT5A gene was marked by bivalent domains containing repressive marks (H3K27me3) and active marks (H3K4me3) on promoters. The bivalent domains tended to resolve during inducted differentiation, with removal of the H3K27me3 mark in a JMJD3-dependent manner. When JMJD3 was knocked down in cultured hDPCs, odontogenic differentiation was suppressed. The depletion of JMJD3 epigenetically repressed WNT5A activation by increased H3K27me3 marks. In addition, JMJD3 could physically interact with ASH2L, a component of the MLL complex, to form a coactivator complex, cooperatively modulating H3K4me3 marks on WNT5A promoters. Overall, our study reveals that transcription activities of WNT5A were epigenetically regulated by the negotiated balance between H3K27me3 and H3K4me3 marks and tightly mediated by JMJD3 and MLL coactivator complex, ultimately modulating odontogenic commitment during dental mesenchymal cell differentiation.

Abstract
Objective: To compare the effects of sterilized air and perfluoropropane (C(3)F(8)) tamponades on recovery after vitrectomy for the treatment of idiopathic full-thickness macular hole (IFTMH). Methods: Case control study. Seventy-three eyes of 69 consecutive cases underwent vitrectomy with air (53 eyes) or 10% C(3)F(8) gas (20 eyes) tamponade. Surgical outcomes were retrospectively analyzed between the two groups, including logarithm of the minimal angle of resolution (logMAR) and optical coherence tomography findings like the size of the macular hole and the photoreceptor layer defect. Results: Preoperatively, the mean best corrected visual acuity (BCVA) was (0.10±0.49), the mean hole diameter was (777.9±320.7) μm, and the mean diameter of the photoreceptor layer defect was (1 709.3±516.0) μm in the sterilized air group, while in the C(3)F(8) group, the mean BCVA was (0.07±0.50), the mean hole diameter was (853.9±355.0) μm, and the mean defect diameter was (1 480.5±429.9) μm. The primary closure rate was 90.6% in the sterilized air group and 95.0% in the C(3)F(8) group. One month after surgery, the mean BCVA was (0.17±0.41), and the mean diameter of the photoreceptor layer defect was (820.5±598.0) μm in the sterilized air group, while in the C(3)F(8) group, the mean BCVA was 0.12±0.49, and the mean defect diameter was (762.5±658.0) μm. There was no statistically significant difference in the closure rate (χ(2)=0.019), BCVA (t=-1.689), hole diameter (t=0.837) and diameter of the photoreceptor layer defect (t=0.338) between the two groups(P>0.05). Conclusions: Vitrectomy with sterilized air tamponade is safe and effective for the treatment of IFTMH and even cases with relatively large diameters. (Chin J Ophthalmol, 2017, 53: 327-331).

Abstract
This study proposed a decision tree model to screen upper urinary tract damage (UUTD) for patients with neurogenic bladder (NGB). Thirty-four NGB patients with UUTD were recruited in the case group, while 78 without UUTD were included in the control group. A decision tree method, classification and regression tree (CART), was then applied to develop the model in which UUTD was used as a dependent variable and history of urinary tract infections, bladder management, conservative treatment, and urodynamic findings were used as independent variables. The urethra function factor was found to be the primary screening information of patients and treated as the root node of the tree; Pabd max (maximum abdominal pressure, >14 cmH2O), Pves max (maximum intravesical pressure, ≤89 cmH2O), and gender (female) were also variables associated with UUTD. The accuracy of the proposed model was 84.8%, and the area under curve was 0.901 (95%CI=0.844-0.958), suggesting that the decision tree model might provide a new and convenient way to screen UUTD for NGB patients in both undeveloped and developing areas.

Abstract
Objective: To evaluate the clinical effectiveness of salvianolic acid B (SA-B) and triamcinolone acetonide (TA) by means of combined intralesional injection in the treatment of oral submucous fibrosis (OSF). Methods: According to clinical findings and symptoms, TA combined with SA-B were consecutively applied intralesionally 1 time weekly for 30 times. Mouth opening degree, color change of the buccal mucosae and numeral increase of the capillary vessels were determined by degree Ⅰ-Ⅳ visual analog scale were evaluated at 12, 24, and 36 months, respectively. Results: One hundred and fourteen subjects fulfilled the study without obvious adverse reactions. After treatment for 1 year, the net gain in mouth opening of the early stage group was (5.5 ± 1.5) mm at 12 months, (8.8 ± 1.6) mm at 24 months and (12.0±1.2) mm at 36 months. The net gain in mouth opening of the middle stage group were (5.3±1.7) mm at 12 months, (10.5±1.5) mm at 24 months and (14.5±2.4) mm at 36 months. The net gain in mouth opening of the advanced stage group were (5.7±1.3) mm at 12 months, (13.7±1.3) mm at 24 months and (15.5±1.5) mm at 36 months. The effective rates of color change of the buccal mucosae and numeral increase of the capillary vessels after treatment for 36 months were 100% in early stage group, 93% (51/55) in middle stage group and 90% (36/40) in advanced stage group. Conclusions: TA and SA-B combined intralesional injection in the treatment of oral submucous fibrosis is effective.

Fuelling the mechanisms of asthma: Increased fatty acid oxidation in inflammatory immune cells may represent a novel therapeutic target. Clin Exp Allergy 2017; 47:1170-1184.

Abstract
BACKGROUND Increasing evidence has shown the close link between energy metabolism and the differentiation, function, and longevity of immune cells. Chronic inflammatory conditions such as parasitic infections and cancer trigger a metabolic reprogramming from the preferential use of glucose to the up-regulation of fatty acid oxidation (FAO) in myeloid cells, including macrophages and granulocytic and monocytic myeloid-derived suppressor cells. Asthma is a chronic inflammatory condition where macrophages, eosinophils, and polymorphonuclear cells play an important role in its pathophysiology. OBJECTIVE We tested whether FAO might play a role in the development of asthma-like traits and whether the inhibition of this metabolic pathway could represent a novel therapeutic approach. METHODS OVA- and house dust mite (HDM)-induced murine asthma models were used in this study. RESULTS Key FAO enzymes were significantly increased in the bronchial epithelium and inflammatory immune cells infiltrating the respiratory epithelium of mice exposed to OVA or HDM. Pharmacologic inhibition of FAO significantly decreased allergen-induced airway hyperresponsiveness, decreased the number of inflammatory cells, and reduced the production of cytokines and chemokines associated with asthma. CONCLUSIONS AND CLINICAL RELEVANCE These novel observations suggest that allergic airway inflammation increases FAO in inflammatory cells to support the production of cytokines, chemokines, and other factors important in the development of asthma. Inhibition of FAO by re-purposing existing drugs approved for the treatment of heart disease may provide a novel therapeutic approach for the treatment of asthma.

Abstract
A Tm3+ ion and Y3+ ion co-doped CaF2 crystal was grown and characterized, in which spectral and lasing performance was presented for the first time, to the best of our knowledge. Under diode end-pumping, in a continuous-wave regime, maximum output power of 453 mW was delivered under an absorption pump power of 2.5 W, corresponding to an optical-to-optical conversion efficiency of 17.9% and a slope efficiency of 21%. With a birefringent quartz plate, wavelength-tunable operation with a tunable range of more than 190 nm was realized. The results show that Tm,Y:CaF2 is a promising laser crystal operating in a spectral region ranging from 1850 nm to 2050 nm.
