Abstract
Objective: To study the spatial-temporal dynamical features of hand-foot-mouth disease (HFMD) in Shaanxi Province, so as to provide evidence for the development of relative prevention and control programs on HFMD. Methods: Surveillance data of HFMD was collected from the China Information System for Diseases Control and Prevention from 2009 to 2013. Related data on population and gross domestic product (GDP) was obtained from Shaanxi Statistical Yearbook. Statistical tools as R3.4.1, ArcGIS 10.2 and SaTScan 9.2 software were used to describe the spatial-temporal distribution of the disease. Power-law method on spatial-temporal-multicomponent model was used to analyze the spatial-temporal evolution of the HFMD epidemics in Shaanxi Province. Results: A total of 229 904 cases of HFMD were reported in Shaanxi Province from 2009 to 2013, with an average annual incidence as 122.50 per 100 000. Obvious seasonal characteristics were noticed, with 71.71% of the total cases identified between April and July. Counties with high incidence were mainly distributed in the mid-and east parts of Guanzhong area. Through temporal and spatial scan statistics, we identified that ClassⅠ clustering area was fixed to the central and southeast regions of Shaanxi province which were around Xi'an City between 2009 and 2013, with the relative risk (RR) as 2.24, ranging from 2.18 to 3.08. Results from Power-law analysis showed that the continuous follow-up impact from the previous HFMD epidemics appeared strong in Tongguan, Pucheng districts of Weinan City and Weiyang district of Xi'an, with autoregressive components as 1.14, 0.97 and 0.89, respectively. The risk of HFMD seemed high in Huayin city, Changan and Yanta districts and with the endemic components as 5.08, 4.12 and 4.08, respectively. Impact of the epidemics on nearby districts was largely seen in Lianhu district of Xi'an, Wugong district of Xianyang and Gaoling district of Xi'an with epidemic components as 2.12, 2.08 and 1.77, respectively. The etiological constituents of HFMD were mainly Enterovirus 71 between 2009 and 2012, while HFMD was mainly caused by other entero-viruses, in 2013. Conclusion: Significant spatial-temporal heterogeneity of HFMD was seen in Shaanxi province, which called for specific strategies to be developed in the highly endemic areas.

Abstract
Transparent tubes with functions of heating and temperature measurement are badly required in the visualization investigation of two-phase flows and flow-boiling heat transfer. In order to prepare such a tube, we introduced a cost-effective and energy-efficient procedure of hypergravity-assisted chemical liquid deposition (HACLD) to produce transparent and conductive silver (Ag) films on the inner surfaces of quartz tubes, typically 50 mm in length and 8 mm in inner diameter with a set-up that was designed and built for this purpose. Precursors of organometallic Ag precursor solutions were prepared by dissolving silver citrate and 1,2-diaminopropane in 2-methoxyethanol with required concentration for the chemical liquid deposition process. Semitransparent and conductive Ag films formed inside the required quartz tubes under specific heating process in hypergravity. One of the films was about 47 nm in thickness, 23 Ω per square sheet resistance, and 30% optical transmittance. This attempt may pave a way for the understanding of the film forming mechanism in hypergravity, and the development of a film preparation technology of HACLD.

Abstract
Midbrain dopamine neurons are crucial for many behavioral and cognitive functions. As the major excitatory input, glutamatergic afferents are important for control of the activity and plasticity of dopamine neurons. However, the role of glutamatergic input as a whole onto dopamine neurons remains unclear. Here we developed a mouse line in which glutamatergic inputs onto dopamine neurons are specifically impaired, and utilized this genetic model to directly test the role of glutamatergic inputs in dopamine-related functions. We found that while motor coordination and reward learning were largely unchanged, these animals showed prominent deficits in effort-related behavioral tasks. These results provide genetic evidence that glutamatergic transmission onto dopaminergic neurons underlies incentive motivation, a willingness to exert high levels of effort to obtain reinforcers, and have important implications for understanding the normal function of the midbrain dopamine system.

Abstract
Quantum networks will enable extraordinary capabilities for communicating and processing quantum information. These networks require a reliable means of storage, retrieval, and manipulation of quantum states at the network nodes. A node receives one or more coherent inputs and sends a conditional output to the next cascaded node in the network through a quantum channel. Here, we demonstrate this basic functionality by using the quantum interference mechanism of electromagnetically induced transparency in a transmon qubit coupled to a superconducting resonator. First, we apply a microwave bias, i.e., drive, to the qubit-cavity system to prepare a Λ-type three-level system of polariton states. Second, we input two interchangeable microwave signals, i.e., a probe tone and a control tone, and observe that transmission of the probe tone is conditional upon the presence of the control tone that switches the state of the device with up to 99.73% transmission extinction. Importantly, our electromagnetically induced transparency scheme uses all dipole allowed transitions. We infer high dark state preparation fidelities of >99.39% and negative group velocities of up to -0.52±0.09 km/s based on our data.

Abstract
Abstract
Breast cancer is a commonly diagnosed cancer of pregnancy. However, how endogenous and exogenous endocrine factors may contribute to the development of pregnancy-associated mammary tumorigenesis is not clear. There is growing evidence that mammary stem cells (MaSCs) may initiate neoplastic transformation when dysregulated in mouse models. We investigated the effect of the environmental endocrine disruptor bisphenol A (BPA) on mouse mammary gland morphology, epithelial cell composition, pre-neoplastic lesions, and the regenerative function of MaSCs. Pregnant FVB mice with GFP transgene on Day E8.5 were implanted with osmotic pumps that constantly release BPA at 0, 25 or 250 ng/kg/day for 28 days and the mice were euthanized one month after weaning. In agreement with the literature, we observed an abnormality of the morphology of the mammary gland after BPA treatment characterized by higher duct density and abnormal secondary and tertiary branching. Quantification of percent hyperplastic mammary ducts in H&E-stained tissue slides revealed a significant increase of ducts with hyperplastic lesions after BPA treatment, particularly with the low dose. To investigate the effects of BPA treatment on MaSCs, we used enzyme digestion to isolate the CD24hi/CD49f+ luminal epithelial cells (also termed as colony forming cell or CFC) and the CD24+/CD49fhi basal epithelial cells (also termed as mammary repopulating unit or MRU) from mammary gland tissues by FACS and found no significant difference in percent of luminal or basal cell population after BPA treatment. Because the basal cells are enriched with MaSCs that can form mammospheres in suspension culture and subsequently form solid 3D organoids when cultured in Matrigel, we transplanted the solid 3D organoids into cleared mammary fat pads of syngeneic FVB mice and immune-compromised nude mice to examine how BPA treatment might alter MaSC function. Significantly, similar to the results from the primary mammary glands, the regenerated mammary glands by MaSCs from mice treated with the low dose of BPA showed increased duct density, secondary and tertiary branching, and a significantly greater number of hyperplastic lesions. Taken together, our study demonstrated that BPA exposure at very low dose could induce pre-neoplastic lesions in the mammary gland of pregnant mice, apparently by directly targeting MaSCs and implicates BPA as an exogenous endocrine factor that may promote pregnancy-associated mammary tumorigenesis.

Abstract
Abstract
Background: Epithelial-to-Mesenchymal Transition (EMT)is postulated to be an important step in cancer progression and controlled by multiple mechanisms including EMT transcription factors (EMT-TFs) and splicing factors such as Epithelial Splicing Regulatory Proteins (ESRP1 and ESRP2). We previously have shown that the expression of ESRP1 and ESRP2 have significantly elevated in cases with high Oncotype DX scores and in ERα-positive cells with acquired endocrine resistance (SABCS 2013). This study seeks to identify the role of EMT-TFs and ESRP1s in the determination of outcomes of patients with ER+ breast cancer.
Patients and Methods: The expression of EMT-TFs and ESRP1 was analyzed in the Affymetrix microarray and TCGA BRCA databases. Next, we generated genetically engineered knockdown models of ESRP1 to understand its functional role in endocrine resistance. We performed RNA-seq and MATS analysis to identify alternative splicing events (ASEs) between ESRP1 knockdown and control cell lines [(2C3 vs 2-control (LCC2 set) and 9C2 vs 9-control(LCC9 set)]. Validation of the ASEs was performed using a probe-based platform [Human Transcriptome Array 2.0 (HTA)] and TCGA SpliceSeq from breast tumors.
Results: High levels of ESRP1 mRNA, but not EMT-TFs, are associated with poor prognosis in human ER+ breast tumors (Affymetrix; P=2.8e-07 and TCGA; P=0.00011). Knockdown of ESRP1 in ER+ endocrine resistant breast cancer induced glandular differentiation, rather than mesenchymal features. This was associated with significant reduction in cell and tumor growth in mammary fat pad orthotopic xenograft mice models of LCC2 and LCC9. No alterations in EMT-TFs were observed in these cells. Transcriptome profiling of ESRP1 knockdown cells further revealed altered ASEs in EMT splicing gene signature, but not at the gene level. These alterations (SE-skipped exon) were further validated for ARHGEF11, ENAH, FNIP1, SCRIB, and SLK using probe based HTA platform for ESRP1 knockdown cells and TCGA-SpliceSeq ER+ BRCA tumors in ER+ ESRP1low versus ESRP1high breast tumors.
Conclusions: Our data demonstrates for the first time that high ESRP1 is associated with poor prognosis in ER+ breast cancer. Despite its involvement in regulation of EMT splicing signature, low levels (or knockdown) of ESRP1 were not associated with EMT phenotype in tumors or in endocrine-resistant ER+ cells. Taken together, our findings indicate that EMT is not important in determining prognosis in ER+ breast cancer and that ESRP1 exerts a different role in aggressive ER+ breast cancers.

Abstract
A highly efficient electrophilic addition of 3-diazooxindoles to H-phosphine oxides under metal-free and base-free conditions is established, leading to phosphinic hydrazides. This method has good chemoselectivity and broad substrate diversity, and provides a facile and green approach for N–P bond formation. The stereoselective synthesis represents a unique example of asymmetric electrophilic addition of diazo compounds as N-terminal electrophiles with phosphorus compounds, affording P-stereogenic phosphinic hydrazides with excellent stereoselectivity.

In addition, in the Figure1f legend, the first sentence should end with "(Cre/tdTomato: n = 10, F4Cre/tdTomato: n = 14)".In the 'Materials and Methods' section, under 'Electrophysiology,' the n values for evoked action potential recordings were omitted. The sentence 'For high-frequency stimulus-induced action potentials, the stimulus electrode was placed in the rostral part of VTA and a train of 100 Hz stimuli (1 s) was applied' should end with '(Cre/tdTomato: n=10, F4Cre/tdTomato: n=14).'Later in the same paragraph, in 'For recording evoked EPSCs (Cre/tdTomato, n=13, F4Cre/tdTomato, n=15; AMPA EPSCs were recorded at -70 mV and NMDA EPSCs were recorded at +40 mV)', the phrase 'Cre/tdTomato, n=13, F4Cre/tdTomato, n=15' should be deleted; those n values should have appeared at the end of the later sentence beginning 'Miniature ESPCs...'. The complete, corrected sentence is 'Miniature EPSCs (mEPSCs) were acquired in the presence of 0.5-1 μM TTX and 100 μM picrotoxin and semiautomatically detected by offline analysis using in-house software in Igor Pro (Wavemetrics, Portland, OR, USA) (Cre/tdTomato, n=13, F4Cre/tdTomato, n=15).'Finally, in the 'Materials and Methods' section, third sentence under 'Immunohistochemistry,' information for one TH antibody was omitted. The list of antibodies should end with 'or Millipore MAB5280, 1:1000-1:2000.'

Abstract
Krabbe disease (KD) is a rare disease caused by the deficiency of β-galactocerebrosidase. This study investigated 22 unrelated Chinese patients, including their clinical presentations, plasma psychosine levels and β-galactocerebrosidase gene mutations. We found the late-onset form of KD present in 82% of the patients in our study, which was more prevalent than in patients from other populations. Plasma psychosine levels were elevated in KD, which were correlated with the severity of clinical presentations. Sanger sequencing identified 8 novel mutations, including 7 missense mutations, p.H253Y, p.S259L, p.P318L, p.F350V, p.T428A, p.L530P, p.G586D, and 1 splicing mutation, c.1251+1G>A. Quantitative real-time polymerase chain reaction (PCR) and multiplex ligation-dependent probe amplification identified a novel exon 12 and 14 deletion, separately. Next generation sequencing, applied at the final step, revealed 2 missense mutant alleles missed using Sanger sequencing. The most common mutation in Chinese population is p.P154H, which accounts for 20.5% of alleles. Consistent with the higher prevalence of the late-onset form of KD, missense mutations predominated in our study, different with the common mutation types in Europe and Japan. This work was the first large-scale study of Chinese KD patients describing their clinical, biochemical and genetic characteristics, which furthered our understanding of this classical neurological lysosomal storage disease.

Abstract
AIMS Minimally invasive transforaminal lumbar interbody fusion (MITLIF) has been well validated in overweight and obese patients who are consequently subject to a higher radiation exposure. This prospective multicentre study aimed to investigate the efficacy of a novel lumbar localisation system for MITLIF in overweight patients. PATIENTS AND METHODS The initial study group consisted of 175 patients. After excluding 49 patients for various reasons, 126 patients were divided into two groups. Those in Group A were treated using the localisation system while those in Group B were treated by conventional means. The primary outcomes were the effective radiation dosage to the surgeon and the exposure time. RESULTS There were 62 patients in Group A and 64 in Group B. The mean effective dosage was 0.0217 mSv (standard deviation (sd) 0.0079) in Group A and 0.0383 mSv (sd 0.0104) in Group B (p < 0.001). The mean fluoroscopy exposure time was 26.42 seconds (sd 5.91) in Group A and 40.67 seconds (sd 8.18) in Group B (p < 0.001). The operating time was 175.56 minutes (sd 32.23) and 206.08 minutes (sd 30.15) (p < 0.001), respectively. The mean pre-operative localisation time was 4.73 minutes (sd 0.84) in Group A and 7.03 minutes (sd 1.51) in Group B (p < 0.001). The mean screw placement time was 47.37 minutes (sd 10.43) in Group A and 67.86 minutes (sd 14.15) in Group B (p < 0.001). The pedicle screw violation rate was 0.35% (one out of 283) in Group A and 2.79% (eight out of 287) in Group B (p = 0.020). CONCLUSION The study shows that the localisation system can effectively reduce radiation exposure, exposure time, operating time, pre-operative localisation time, and screw placement time in overweight patients undergoing MITLIF.

Abstract
The observation and manipulation of electron dynamics in matter call for attosecond light pulses, routinely available from high-order harmonic generation driven by few-femtosecond lasers. However, the energy limitation of these lasers supports only weak sources and correspondingly linear attosecond studies. Here we report on an optical parametric synthesizer designed for nonlinear attosecond optics and relativistic laser-plasma physics. This synthesizer uniquely combines ultra-relativistic focused intensities of about 1020 W/cm2 with a pulse duration of sub-two carrier-wave cycles. The coherent combination of two sequentially amplified and complementary spectral ranges yields sub-5-fs pulses with multi-TW peak power. The application of this source allows the generation of a broad spectral continuum at 100-eV photon energy in gases as well as high-order harmonics in relativistic plasmas. Unprecedented spatio-temporal confinement of light now permits the investigation of electric-field-driven electron phenomena in the relativistic regime and ultimately the rise of next-generation intense isolated attosecond sources.

Abstract
Genetically engineered bacteria can be used for a wide range of applications, from monitoring environmental toxins to studying complex communication networks in the human digestive system. Although great strides have been made in studying single strains of bacteria in well-controlled microfluidic environments, there remains a need for tools to reliably control and measure communication between multiple discrete bacterial populations. Stable long-term experiments (e.g., days) with controlled population sizes and regulated input (e.g., concentration) and output measurements can reveal fundamental limits of cell-to-cell communication. In this work, we developed a microfluidic platform that utilizes a porous monolith to reliably and stably partition adjacent strains of bacteria while allowing molecular communication between them for several days. We measured small molecule production by the bacterial populations in response to stimuli using analytical chemistry methods and measured fluorescent output. The results are compared with communication and diffusion delay models. This porous monolith microfluidic system enables bacterial cell-to-cell communication assays with dynamic control of inputs, relatively long-term experimentation with no cross contamination, and stable bacterial population size. This system can serve as a valuable tool in understanding bacterial communication and improving biosensor design capabilities.

Abstract
Objective:To study whether serum 25-hydroxy vitamin D can be used as an independent indicator of prognosis in patients with benign paroxysmal positional vertigo. Method:Two hundred and two patients with BPPV were collected and divided into vitamin D deficiency group and control group according to their serum 25-OHD level. The severity of the symptoms and the recurrence rate were compared between the two groups. Result:Compared with the control group, patients with vitamin D deficiency group showed severer symptoms, either in longer duration of vertigo, lower success rate of repositioning maneuver treatment at the first time, or higher recurrence rate within six months. Conclusion:Serum 25-OHD level was negatively correlated with the severity and prognosis of BPPV, and could be used as an important index to evaluate the prognosis of BPPV.

Abstract
Abstract
Age is the number one risk factor for breast cancer development. The breast cancer incidence rate increases with age, following beta distribution, which is approximately linear in range from 30 to 70 years old [1]. Transcriptome alterations have been shown to promote tumorigenesis for many types of cancers. Therefore, we hypothesize that the genes with altered expression during aging may promote breast cancer development and/or progression. Using The Cancer Genome Atlas data, we extracted whole transcriptome profiling data of matched normal tissues from 82 female patients with age at diagnosis and menopausal status available. First, we applied simple linear regression to study the association between gene expression level and age at diagnosis on all the 82 patients. 258 upregulated and 240 downregulated genes are identified, which are associated with age. Secondly, 493 upregulated and 254 downregulated genes are identified that are altered by menopause by comparing post-menopausal to pre-menopausal patients (FDR < 0.05). Exclusion of these menopause affected genes from those genes affected by age (258 upregulated and 240 downregulated) results in 148 upregulated and 189 downregulated genes during aging. Thirdly, by comparing matched tumor and adjacent normal samples, 3356 upregulated and 3124 downregulated genes are found to be associated with tumorigenesis. Overlapping of tumorigenesis associated genes with age dependent genes result in 14 upregulated and 24 downregulated genes that are both age and tumorigenesis associated. This discovery is being validated with normal breast tissues from donors in GTEx cohort. Experimental manipulation of the upregulated genes in seven breast cancer cell lines, representing five subtypes of breast cancer, demonstrated their essential role in promoting tumor malignancy, suggesting the upregulation is not merely passenger event. In a large mixed cohort, this panel of genes have significant predictive value in relapse free survival of breast cancer patients.

Abstract
BACKGROUND Obesity is strongly linked to increased blood pressure, which increases the risk of cardiovascular diseases. To our knowledge, little literature reported the information about galanin levels in obese individuals with hypertension. Therefore, the aim of this study was to investigate the possible involvement of galanin in the pathogenesis of obese subjects with hypertension. METHODS We measured body mass index and blood pressure of 38 obese patients with hypertension, 44 obese controls with normal blood pressure and 44 lean controls with normal blood pressure. Blood samples from all cases were collected at 8:00 a.m. after an overnight fast to determine the fasting plasma concentration of galanin, glucose, insulin, triglyceride, total cholesterol, high- and low-density lipoprotein cholesterol. RESULTS We found that plasma galanin levels were significantly decreased in obese patients with hypertension compared with the obese control group, whereas the galanin levels were significantly increased in obese controls compared with lean controls. Furthermore, in both obese groups the galanin levels were negatively correlative to diastolic blood pressure and positively correlative to insulin and triglyceride levels, but not to heart rate. CONCLUSIONS Low galanin levels were one of characters of obese patients with high blood pressure, and this levels may be taken as a novel biomarker to predict the development of high blood pressure in obese patients.

Abstract
Objective:To explore the characteristic of lexical tone perception in native-Mandarin speakers with mild to moderate sensorineural hearing loss. Method:Three types of continuum(Tone1/tone2, tone1/tone4 and tone2/tone3) were constructed and each of them includes a 15 stimuli. All speech stimuli in these three continua were resynthesized by applying the Pitch-Synchronous OverLap and Add(PSOLA) method implemented in Praat to the same mandarin syllable, /a/, with a high level tone produced by a female native-mandarin speaker. Twenty-three native-mandarin sensory hearing loss people were recruited for this study and identification task was used to acquire the tonal perceptual data. SPSS 19.0 software was used to get the fitting curves of lexical tone perception. Result:①Each tone perception curves owns the characteristic of categorical perception, including an obvious boundary, a definite intersection and the abrupt performance change at intersection. The tone perception curves were S-shape in SNHL people which were same as that in normal hearing people.②No significant performance difference of each continuum was observed between SNHL and NH in this study(P=0.811 in T1/T2 continuum, P=0.528 in T1/T4 continuum, P=0.555 in T2/T3 continuum). Conclusion:There is the categorical perception of lexical tone identification in native-mandarin sensorineural hearing loss people. The slight damage in peripheral auditory system did not changed characteristic of lexical tone perception.

Abstract
Glucagon-like peptide 1 (GLP-1), a kind of gut hormone, is used in the treatment of type 2 diabetes (T2D). Emerging evidence indicates that GLP-1 has anti-inflammatory activity. Chronic inflammation in the adipose tissue of obese individuals is a cause of insulin resistance and T2D. We hypothesized that GLP-1 analogue therapy in patients with T2D could suppress the inflammatory response of macrophages, and therefore inhibit insulin resistance. Our results showed that GLP-1 agonist (exendin-4) not only attenuated macrophage infiltration, but also inhibited the macrophage secretion of inflammatory cytokines including TNF-β, IL-6, and IL-1β. Furthermore, we observed that lipopolysaccharide (LPS)-induced macrophage conditioned media could impair insulin-stimulated glucose uptake. This effect was compensated by treatment with the conditioned media from macrophages treated with the combination of LPS and exendin-4. It was also observed that exendin-4 directly inhibited the activation of NF-κB in macrophages. In conclusion, our results indicated that GLP-1 improved inflammatory macrophage-derived insulin resistance by inhibiting NF-κB pathway and secretion of inflammatory cytokines in macrophages. Furthermore, our observations suggested that the anti-inflammatory effect of GLP-1 on macrophages can contribute to GLP-1 analogue therapy of T2D.

Abstract
The acute respiratory distress syndrome (ARDS), a clinical complication of severe acute lung injury (ALI) in humans, is a leading cause of morbidity and mortality in critically ill patients. Here, we explored the association between IL-17 and development of ALI using LPS-induced murine model. We found that IL-17 level was elevated in bronchoalveolar lavage (BAL) fluid of ALI mice. Upregulation of IL-17 resulted in increased severity of ALI as evidenced by decreased body weight and survival rate, elevated level of total protein and albumin in BAL fluid, as well as more apparent histopathology changes of lung. Induction of ALI was impaired in IL-17-deficient mice. Management of IL-17 could modulate LPS-induced pulmonary inflammation, as reflected by the total cell and neutrophil counts, proinflammatory cytokines, as well as chemokines in BAL fluid. Of note, blockade of IL-17 effectively inhibited the lung inflammation and alleviated ALI severity. Finally, we confirmed the clinical relevance and found that IL-17 expression was elevated and associated with the disease severity in patients with ARDS. In essence, IL-17 was crucial for development of ALI, suggesting a potential application for IL-17-based therapy in clinical practice.
