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
OBJECTIVE To assess the association of cognitive impairment and clinical symptoms in first-episode schizophrenia with the Val66Met (rs6265) polymorphism of brain-derived neurotrophic factor (BDNF) gene. METHODS For 87 patients with first-episode schizophrenia and 76 healthy controls, the Val66Met polymorphism was determined with a Taqman Assay-on-Demand method. Wechsler intelligence test was carried out for all participants. Correlation of cognitive impairment with clinical severity was also analyzed. RESULTS The patients were significantly lower in total IQ, verbal IQ and performance IQ compared to the controls. The lower total IQ (F=4.59, P= 0.01) and verbal IQ (F=4.44, P=0.01) were influenced by genetic factors and diagnostic interaction. The vertal IQ of Val/Val patients was significantly lower than those of Val/Met and Met/Met carriers. For the control group, the verbal IQ of Met/Met carriers was lower than that of Val/Met carriers, and the total IQ of Met/Met carriers was lower than those of Val/Met and Val/Val carriers. For the patient group, the total IQ of Val/Val carriers was negatively correlated with positive symptoms (r=-0.65, P=0.03) and thought disorders (r=-0.61, P=0.02). CONCLUSION Cognitive impairment in first-episode schizophrenic patients is associated with the Val66Met polymorphism of the BDNF gene, and has an important clinical relevance.

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.

Abstract
A critical aspect of highly potent regimens such as lung stereotactic body radiation therapy (SBRT) is to avoid collateral toxicity while achieving planning target volume (PTV) coverage. In this work, we describe four dimensional conformal radiotherapy using a highly parallelizable swarm intelligence-based stochastic optimization technique. Conventional lung CRT-SBRT uses a 4DCT to create an internal target volume and then, using forward-planning, generates a 3D conformal plan. In contrast, we investigate an inverse-planning strategy that uses 4DCT data to create a 4D conformal plan, which is optimized across the three spatial dimensions (3D) as well as time, as represented by the respiratory phase. The key idea is to use respiratory motion as an additional degree of freedom. We iteratively adjust fluence weights for all beam apertures across all respiratory phases considering OAR sparing, PTV coverage and delivery efficiency. To demonstrate proof-of-concept, five non-small-cell lung cancer SBRT patients were retrospectively studied. The 4D optimized plans achieved PTV coverage comparable to the corresponding clinically delivered plans while showing significantly superior OAR sparing ranging from 26% to 83% for D max heart, 10%-41% for D max esophagus, 31%-68% for D max spinal cord and 7%-32% for V 13 lung.

Abstract
Culicoides (Diptera: Ceratopogonidae) midges are the biological vectors of a number of arboviruses of veterinary importance. However, knowledge relating to the basic biology of some species, including their host-feeding preferences, is limited. Identification of host-feeding preferences in haematophagous insects can help to elucidate the transmission dynamics of the arboviruses they may transmit. In this study, a series of semi-quantitative real-time polymerase chain reaction (qPCR) assays to identify the vertebrate host sources of bloodmeals of Culicoides midges was developed. Two pan-reactive species group and seven species-specific qPCR assays were developed and evaluated. The assays are quick to perform and less expensive than nucleic acid sequencing of bloodmeals. Using these assays, it was possible to rapidly test nearly 700 blood-fed midges of various species from several geographic locations in Australia.

Abstract
Small-angle neutron scattering (SANS) measurements from thin sections of rock samples such as shales demand as great a scattering vector range as possible because the pores cover a wide range of sizes. The limitation of the scattering vector range for pinhole SANS requires slit-smeared ultra-SANS (USANS) measurements that need to be converted to pinhole geometry. The desmearing algorithm is only successful for azimuthally symmetric data. Scattering from samples cut parallel to the plane of bedding is symmetric, exhibiting circular contours on a two-dimensional detector. Samples cut perpendicular to the bedding show elliptically dependent contours with the long axis corresponding to the normal to the bedding plane. A method is given for converting such asymmetric data collected on a double-crystal diffractometer for concatenation with the usual pinhole-geometry SANS data. The aspect ratio from the SANS data is used to modify the slit-smeared USANS data to produce quasi-symmetric contours. Rotation of the sample about the incident beam may result in symmetric data but cannot extract the same information as obtained from pinhole geometry.

Abstract
We investigate the various contributions to the temperature dependence of an interferometric fiber-optic current sensor employing spun highly-birefringent sensing fiber, in particular, the contributions from the fiber retarder at the fiber coil entrance, the spun fiber's birefringence, and the Faraday effect. We theoretically and experimentally demonstrate that an appropriately designed retarder inherently compensates the temperature dependence of the fiber birefringence and the Faraday effect. We demonstrate insensitivity to temperature to within ± 0.2% between -40 and + 85 °C. Furthermore, we analyze the influence of the retarder parameters on the linearity of the recovered magneto-optic phase shift vs. current and determine a set of parameters that results in a perfectly linear relationship.

Abstract
OBJECTIVE To investigate the long-term effect of biventricular (BIV) and right ventricular apical (RVA) pacing on cardiac function in patients with high-degree atrioventricular block (AVB) and left ventricular ejection fraction(LVEF)over 35%. METHODS A total of 118 consecutive patients with high-degree AVB in six hospitals from East China between May 2009 and December 2012 were enrolled in this randomized, double-blind and parallel controlled study. Patients were randomly assigned to BIV and RVA pacing with or without LV lead on after one-week cardiac resynchronization therapy (CRT). Cardiac function including New York Heart Association(NYHA), 6 minute walking distance (6MWD), Minnesota living with heart failure (MLHF) score, LVEF, left ventricular end-diastolic volumes/diameters (LVEDV/LVEDD) and other echocardiography parameters, as well as N-terminal pro-B-type natriuretic peptide (NT-proBNP)were assessed at 6 months and 12 months. RESULTS A total of 114 patients were successfully implanted with CRT. Cardiac function was significantly improved after one-week BIV pacing (n=57) compared with pre-CRT: rate of patients with NYHA Ⅲ (25.44%(29/114) vs. 9.65%(11/114)), MLHF score (17.1±13.6 vs. 26.9±21.6), 6MWD ((315.4±121.8)m vs. (291.8±102.9)m) and NT-proBNP (157.0(70.0, 639.0) ng/L vs. 444.7(144.0, 1 546.0)ng/L, all P<0.05). In BIV group, 6MWD extended from (314.8±142.7)m to (332.7±117.5)m at 6 months (P<0.05), LVEF increased from (60.7±7.9)% at 1 week to (56.6±10.7)% at 6 months(P<0.05), both LVEDV and LVEDD decreased at 12 months compared with at 1 week ((116.2±39.5)ml vs. (131.4±49.6)ml and (50.2±5.6)mm vs. (52.5±6.8)mm, P<0.05). In RVA group (n=57), 6MWD increased at 6 months compared that at 1week ((342.4±109.9)m vs. (310.2±105.1)m, P<0.05), NT-proBNP was higher at 12 months than that at 1 week (349.5(191.8, 884.3)ng/L vs. 127.0(70.3, 336.7)ng/L, P<0.05). Compared with RVA group, BIV group had a bigger shrink in LVEDV decrease at 12 months was more significant in BIV group ((-16.68±24.30)ml vs. (9.09±29.30)ml, P<0.05). CONCLUSIONS Cardiac pacing could acutely improve the cardiac function in patients with high-degree AVB and LVEF over 35%. Improvements on cardiac function and remodeling are more significant after 12-month BIV pacing than that of RVA pacing. Clinical Trail Registry: Chinese Clinical Trial Registry, ChiCTR-TRC-10000832.
