Abstract
We investigated the vortex pinning behavior in the single crystal topological superconductor Cu0.10Bi2Se3 with a pronounced anisotropic peak effect. A weak collective pinning regime is clarified from the power-law behavior in [Formula: see text] and the small critical current density ratio of [Formula: see text] ~ 10-5 ([Formula: see text] is the critical current density, [Formula: see text] is the depairing current density). The spatial variation of the charge-carrier mean free path induced pinning is evidenced and probably results from the well-defined atomic defects. Within the framework of collective pinning theory, we computed the values of the correlated length and volume at 1.8 K, which start declining prior to the onset field of the peak effect [Formula: see text], demonstrating the vortex lattices already suffered a preferential collapse ahead of the peak effect turns up. Thus, the peak effect can be understood by elastic moduli softening near the upper critical field [Formula: see text]. We suggest Cu x Bi2Se3 is a prototype topological material for investigating the vortex pinning dynamics associated with the peak effect phenomenon.

Abstract
The alterations induced in gut microbiota by tacrolimus may affect immune function and organ transplantation. Mice were treated with high-dose tacrolimus for 14 days. The fecal microbiota were analyzed by pyrosequencing the 16S rRNA genes, and the effect on metabolism was predicted using the sequence data. The subgroups of T cells in the serum, gut-associated lymphoid tissue, and draining lymph nodes were determined by flow cytometry. Tacrolimus treatment significantly altered the relative abundance of Allobaculum, Bacteroides, and Lactobacillus and CD4+ CD25hi FoxP3+ regulatory T cells in the colonic mucosa and the circulation. These were significantly increased after either tacrolimus treatment or treatment by fecal microbiota transfer from tacrolimus-treated donors. Further, treatment with low-dose tacrolimus plus fecal microbiota transfer from high-dose tacrolimus-altered mice increased skin allograft survival rate in a skin transplantation model. Thus, high-dose tacrolimus alters the compositions and taxa of the gut microbiota. Administration of these conditioned gut microbiota plus low-dose tacrolimus resulted in regulation of colonic and systemic immune responses and an increased allograft survival rate. This study demonstrated a new strategy for controlling allograft rejection by combining an immunosuppressive agent with gut microbiome transplantation.

Abstract
AIM To investigate whether peer support would reduce diabetes distress and improve glycaemic control when added to usual diabetes education among adults with Type 2 diabetes in China. METHODS We conducted a cluster randomized trial involving 400 adults with Type 2 diabetes from eight communities in Nanjing. All participants received usual education for an average of 2 h each month from physicians, certified diabetes educators, dieticians, psychologists and podiatric nurses. Peer support was led by trained peer leaders and included diabetes knowledge- and skills-sharing at least once a month, as well as peer-to-peer communication. The primary outcome was diabetes distress measured using the Diabetes Distress Scale at 12 months. Secondary outcomes included fasting plasma glucose, 2-h postprandial glucose and HbA1c concentration. Outcome data were collected from all participants at baseline, 6 months and 12 months. RESULTS From 2012 to 2013, there were 200 participants in each study arm at baseline. Compared with the usual education arm, the peer support with usual education arm had greater reductions in regimen-related distress (1.4 ± 0.6 vs 1.2 ± 0.4; P=0.004) and total distress (1.3 ± 0.4 vs 1.2 ± 0.3; P=0.038) at 6 months. At 12 months, the scores for emotional burden (1.2 ± 0.3 vs 1.4 ± 0.6; P=0.002), physician-related distress (1.1 ± 0.3 vs 1.3 ± 0.4; P=0.001) and total scores (1.2 ± 0.3 vs 1.3 ± 0.4; P=0.002) were significantly lower in the peer support with usual education arm than in the usual education arm. Fasting plasma glucose levels were lower in the peer support with usual education arm than in the usual education arm at 6 months (7.5 ± 1.95 vs 8.0 ± 2.2; P=0.044) and 12 months (7.0 ± 2.3 vs 7.6 ± 1.5; P=0.008). CONCLUSIONS Beyond the benefits of usual education, peer support was effective in reducing diabetes distress for Type 2 diabetes mellitus. (Clinical Trials Registry no: NCT02119572).

Abstract
Objective: The aim of this study was to set up a large, longitudinal and prospective database to compare the clinical manifestations in human leucocyte antigen (HLA)-B(27) positive and negative patients with ankylosing spondylitis(AS) based on real-world evidence in Chinese population. Methods: A total of 897 outpatients with confirmed AS were recruited consecutively by smart management system for spondyloarthritis (SMSP) from April 13, 2016 to June 6, 2017 in Chinese PLA General Hospital from 30 provinces and autonomous regions. 801 patients with HLA-B(27) data were included in the analysis. Demographic and clinical parameters including Bath ankylosing spondylitis disease activity index (BASDAI), Bath ankylosing spondylitis functional index (BASFI), ankylosing spondylitis disease activity score (ASDAS), arthritis, enthesitis, Bath ankylosing spondylitis metrology index (BASMI), erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) were compared between HLA-B(27) positive and negative groups. Results: A total of 801 patients were included in the analysis with an average age of (30.7±8.8) years. There were 659 males and 142 females and HLA-B(27) was present in 88.0%(705/801). Males were significantly more in HLA-B(27) positive patients [83.3%(587/705) vs. 75.0%(72/96); P=0.047].The average age at disease onset was (22.3±7.6)years in HLA-B(27) positive patients and (24.4±8.7) years in HLA-B(2)7 negative ones (P=0.028).There was significant difference in diagnose delay between two groups [14.3(2.5,43.6)months in HLA-B(27) positive patients vs. 20.3(5.0,67.4) months in HLA-B(27) negative ones, P=0.041]. Anterior uveitis was found to be significantly more common in HLA-B(27) positive patients [18.9% (133/705)vs.7.3%(7/96),P=0.005], and knee involvement less common in HLA-B(27) positive patients [4.0%(27/682) vs.10.0%(9/90), P=0.010], conversely. CRP[6.5(3.0, 16.4)mg/L vs. 3.5(1.6, 12.3)mg/L] and ESR[11.0(4.0, 24.0)mm/1h vs. 7.0(3.0, 16.0)mm/1h] were significantly higher in HLA-B(27) positive patients(P=0.005,0.013, respectively).But no differences in BASDAI,ASDAS,BASFI and BASMI were obtained between two groups. Conclusions: HLA-B(27) positive patients had a higher proportion of males, a younger age of onset and a greater risk for occurrence of anterior uveitis, suggesting a poorer prognosis.

Abstract
Endothelial cells (ECs) and macrophages engage in tight and specific interactions that play critical roles in cardiovascular homeostasis and the pathogenesis of atherosclerosis. Extracellular vesicles (EVs) are circular membrane fragments released from the endosomal compartment as exosomes or shed from the surfaces of the membranes of most cell types. Increasing evidence indicates that EVs play a pivotal role in cell-to-cell communication. However, the contribution of EVs, as determine by oxidized low-density lipoprotein (ox-LDL)-exposed and/or Kruppel-like factor 2 (KLF2)-transduced ECs in the interaction between vascular ECs and monocytes/macrophages, which is a key event in atherosclerotic plaque development, has remained elusive. This study demonstrates the characteristic impact of EVs from ox-LDL-treated and/or KLF2-transduced ECs on the monocyte/macrophage phenotype in vitro and in vivo.Q-PCR showed that both the atherosclerosis inducer ox-LDL and atheroprotective factor KLF2 regulated inflammation-associated microRNA-155 (miR-155) expression in human umbilical vein endothelial cells (HUVECs). Moreover, coculture, immunofluorescence and flow cytometry revealed that miR-155 was enriched in ox-LDL-induced ECs-EVs and subsequently transferred to human monocytic THP1 cells, in which these vesicles enhance monocyte activation by shifting the monocytes/macrophages balance from anti-inflammatory M2 macrophages towards proinflammatory M1 macrophages; EVs from KLF2-expressing ECs suppressed monocyte activation by enhancing immunomodulatory responses and diminishing proinflammatory responses, which indicate the potent anti-inflammatory activities of these cells. Furthermore, oil red staining showed that atherosclerotic lesions were reduced in mice that received EVs from KLF2-transduced ECs with decreased proinflammatory M1 macrophages and increased anti-inflammatory M2 macrophages, and this effect is at least partly due to the decreased expression of inflammation-associated miR-155, confirming our in vitro findings. In summary, this study provides novel insights into the pathophysiological effects of altered EV secretion and/or microRNA content and their influence on modulating monocyte activation depending on the environment surrounding EVs-releasing ECs.

Abstract
Objective: To observe the correlation between Nε-carboxymethyl-Lysine (CML), the main component of advanced glycation end products and the calcification of the anterior tibial artery plaque in patients with diabetic foot post foot amputation. Methods: Sixty patients hospitalized for foot amputation operation due to diabetic foot from June 2012 to June 2016 in the Department of Orthopedics, Affiliated Hospital of Jiangsu University were prospectively recruited.The patients were categorized into mild stenosis (0<stenosis<50%, n=20), moderate stenosis (50%≤stenosis<70%, n=20) and severe stenosis (70%≤stenosis≤100%, n=20) based on the color Doppler ultrasound assessed severity of anterior tibial artery stenosis.The baseline clinical data of patients were collected and anterior tibial artery was isolated.Then, HE staining, O-Cresolphthalein Complexone method, enzymic method and ELASA analysis were then performed to detect the evolution of calcification, arterial calcium content, alkaline phosphatase activity and serum CML concentration, respectively. Results: The results from both color Doppler ultrasound scan before amputation and HE staining after amputation showed that echo intensity as well as spotty blue calcium particles of anterior tibial artery plaque increased significantly in proportion to degree of stenosis and destructed elastic plate of the arterial wall was evidenced in patients with severest stenosis.The content of calcium ((2.3±0.9), (3.9±1.3), (6.6±1.7) μmol/mg, respectively, P<0.001), ALP activity ((102.4±39.4), (202.3±73.4), (483.7±117.9) U/mg, respectively, P<0.001) and serum CML level ((28.9±4.4), (37.9±5.3), (57.3±7.1)μg/L, respectively, P<0.001) increased significantly in proportion to stenosis severity.Pearson correlation analysis showed that serum CML level was positively correlated with the content of calcium (r=0.749, P<0.001) and ALP activity (r=0.923, P<0.001), respectively. Conclusions: Serum CML level is positively correlated with the calcification of anterior tibial arterial plaque in patients with diabetic foot and could be used to evaluate the calcification of anterior tibial arterial plaque and stenosis degree of anterior tibial arterial in these patients.

Abstract
Abstract
Background: The randomized phase II SNAP trial assessed three alternative reduced maintenance chemotherapy regimens using nab-Paclitaxel after a short term induction phase at conventional doses as first line treatment in patients (pts) with metastatic breast cancer (MBC). For all three regimens median progression-free survival was greater than achieved with full dose docetaxel (historical reference). Symptom palliation and quality of life (QoL) are important when deciding on therapeutic agents and schedules in MBC pts.
Methods: Of the 258 pts with MBC enrolled from April 2013 to August 2015 in the SNAP trial, 255 were included in the QoL analysis. Pts were randomized to three arms, each receiving the same induction chemotherapy based on 3 cycles of nab-Paclitaxel 150 mg/m2 dd 1, 8, 15 Q28, which was reduced to 125 mg/m2 after a safety review. The schedules of nab-Paclitaxel in maintenance therapy differed in each arm: Arm A) 150 mg/m2 dd 1,15 Q28; Arm B) 100 mg/m2 dd 1,8,15 Q28; Arm C) 75 mg/m2 dd 1,8,15,22 Q28. Pts completed a QoL form to assess global and symptom-specific indicators (range 0-100) at baseline, and at day 1 of every cycle for the first 12 cycles on treatment, or until treatment discontinuation. Changes in QoL scores during induction (day 1 cycle 4 − baseline) and maintenance (day 1 cycle 12 – day 1 cycle 4) therapy were summarized descriptively per arm. Treatment effects on changes in QoL during maintenance therapy were analyzed by repeated measurement models including timepoints (from day 1 of cycle 4 to day 1 of cycle 12), induction start dose, age, and treatment arms as covariates.
Results: During induction therapy, mean changes [SD] in hair loss (Arm A:−70.2 [41.9]; Arm B: −77.3 [34.5]; Arm C: −72.6 [32.8]), sensory neuropathy (Arm A: −19.0 [25.2]; Arm B: −20.6 [22.7]; Arm C: −18.8 [23.8]), and treatment burden (Arm A: −12.9 [33.4]; Arm B: −13.4 [33.5]; Arm C: −11.4 [34.8]) showed the most pronounced worsening. During maintenance therapy, scores for sensory neuropathy remained impaired without worsening. No significant differences in changes for sensory neuropathy or the other symptoms were seen between arms, except for hair loss, with pts in arm C (mean difference 10.91; 95% CI [0.35, 21.48]; p=0.04) ] and B (mean difference 18.55; 95% CI [7.52, 29.59]; p=0.001) reporting a greater improvement compared to those in arm A. Pts in arm C reported a significantly greater improvement in mood compared to arm A (mean difference 13.34; 95% CI [6.08, 20.60]; p<0.001) and arm B (mean difference 9.62; 95% CI [2.84, 16.40]; p=0.01)].
Conclusion: The effectiveness of alternative maintenance chemotherapy schedules with reduced doses after a short term induction phase at conventional doses must be weighed against a substantial worsening in sensory neuropathy during induction therapy, and scores continuing to be impaired without worsening with prolonged administration. During maintenance therapy, improvements were seen in the perception of hair loss and in mood, particularly in Arm B and C, with a similar tendency seen for some other QoL domains. A more frequent administration of reduced dose chemotherapy agents is favorable with respect to QoL in this setting.

Abstract
Dielectric materials typically demonstrate poor thermal conductivity, which limits their application in emerging technologies in integrated circuits, computer chips, light-emitting diode lamps, and other electronic packaging areas. Using liquid metal microdroplets as inclusions to develop thermal interface materials has been shown to effectively improve thermal pathways, but this type of material may become electroconductive with the application of a concentrated compressive stress. In this study, an isotropic nano-liquid metal thermally-conductive and electrically-insulating material (nLM-THEM) is developed by combining a modified polymer and well-dispersed nanoparticles, achieving an ∼50× increase in thermal conductivity over the base polymer. In addition, the thermal conductivity of nLM-THEMs exhibits no significant change with varying humidity and a stable anti-corrosion effect even in direct contact with aluminum. More importantly, nLM-THEMs demonstrate a stable electrical insulating property upon compressive stress, while conventional micro-LM-THEMs exude liquid metal. This exceptional combination of thermal and electrical insulation properties is enabled by the interconnection of uniform and spherical liquid metal nanoparticles to create more thermally-conductive pathways, and surfactant modified nanoparticles ensure excellent electric insulation. Moreover, this material can achieve passive heat exchange through rapid heat dissipation, which demonstrates its great application potential in the electronic packaging area. Compared to liquid metal (LM) microdroplets based thermally conductive materials (micro-LM-THEMs), nano LM-THEMs (nLM-THEMs) presents a more stable electric insulating property even upon stress, achieving ~50-fold thermal conductivity over base polymer.![]()

Abstract
We report on design and technology improvements for a flowing liquid lithium (FLiLi) limiter inserted into auxiliary heated discharges in the experimental advanced superconducting tokamak device. In order to enhance Li coverage uniformity and erosion resistance, a new liquid Li distributor with homogenous channels was implemented. In addition, two independent electromagnetic pumps and a new horizontal capillary structure contributed to an improvement in the observed Li flow uniformity (from 30% in the previous FLiLi design to >80% in this FLiLi design). To improve limiter surface erosion resistance, hot isostatic press technology was applied, which improved the thermal contact between thin stainless steel protective layers covering the Cu heat sink. The thickness of the stainless steel layer was increased from 0.1 mm to 0.5 mm, which also helped macroscopic erosion resilience. Despite the high auxiliary heating power up to 4.5 MW, no Li bursts were recorded from FLiLi, underscoring the improved performance of this new design.

Abstract
AIM To examine the overall survival differences for the following neoadjuvant therapy modalities - no therapy, chemotherapy alone, radiation alone and chemoradiation - in a large cohort of patients with locally advanced rectal cancer. METHOD Adults with clinical Stage II and III rectal adenocarcinoma were selected from the National Cancer Database and grouped by type of neoadjuvant therapy received: no therapy, chemotherapy only, radiotherapy only or chemoradiation. Multivariable regression methods were used to compare adjusted differences in perioperative outcomes and overall survival. RESULTS Among 32 978 patients included, 9714 (29.5%) received no neoadjuvant therapy, 890 (2.7%) chemotherapy only, 1170 (3.5%) radiotherapy only and 21 204 (64.3%) chemoradiation. Compared with no therapy, chemotherapy or radiotherapy alone were not associated with any adjusted differences in surgical margin positivity, permanent colostomy rate or overall survival (all P > 0.05). With adjustment, neoadjuvant chemoradiation vs no therapy was associated with a lower likelihood of surgical margin positivity (OR 0.74, P < 0.001), decreased rate of permanent colostomy (OR 0.77, P < 0.001) and overall survival [hazard ratio (HR) 0.79, P < 0.001]. When compared with chemotherapy or radiotherapy alone, chemoradiation remained associated with improved overall survival (vs chemotherapy alone HR 0.83, P = 0.04; vs radiotherapy alone HR 0.83, P < 0.019). CONCLUSION Neoadjuvant chemoradiation, not chemotherapy or radiotherapy alone, is important for sphincter preservation, R0 resection and survival for patients with locally advanced rectal cancer. Despite this finding, one-third of patients in the United States with locally advanced rectal cancer fail to receive stage-appropriate chemoradiation.

Abstract
We report the first dijet transverse momentum asymmetry measurements from Au+Au and pp collisions at RHIC. The two highest-energy back-to-back jets reconstructed from fragments with transverse momenta above 2 GeV/c display a significantly higher momentum imbalance in heavy-ion collisions than in the pp reference. When reexamined with correlated soft particles included, we observe that these dijets then exhibit a unique new feature-momentum balance is restored to that observed in pp for a jet resolution parameter of R=0.4, while rebalancing is not attained with a smaller value of R=0.2.

Abstract
Non-atherosclerotic coronary artery diseases are being increasingly recognised as causes of acute coronary events. Invasive coronary angiography frequently fails to identify the abnormalities in the proximal course of coronary arteries and coronary wall, while computed tomography coronary angiography (CTCA) allows for acquisition of more detailed information. CTCA serves as a reliable method for evaluating patients with non-atherosclerotic coronary artery diseases. The purpose of this article is to provide an overview of non-atherosclerotic abnormalities that may be demonstrated on CTCA.

Abstract
Objective: To investigate the effect of different mechanical loading on the expression of Notch-1, Notch-3, Jagged-1 and Delta-like-1 in growing rabbits' condylar cartilage. Methods: Sixty-four ten-days-old rabbits were randomly divided into experimental and control groups. The rabbits in the experimental groups were fed on a powder diet, while the control groups were fed on a solid diet. The animals were sacrificed after 2, 4, 6 and 8 weeks. Notch-1, Notch-3, Jagged-1 and Delta-like-1 gene and protein expressions were examined by HE, immunohistochemistry, Western blotting and quantitative real-time PCR. Results: At 2, 4, 6, 8 weeks, the anterior part of condylar cartilage in solid diet groups ([318.1±4.3], [342.4±2.6], [364.2±3.2], [380.7±6.0] mm, respectively) were thicker than those in powder diet groups ([275.4±2.6], [301.1±2.0], [322.3±3.3], [366.5±8.4] mm, respectively) (P<0.05). There was no significant difference between the two groups in the middle part (P>0.05). From 2 to 6 weeks, the posterior part of cartilage in solid diet groups ([444.1±1.5], [451.1±0.3], [476.4±5.7] mm, respectively) was thinner than those in power diet groups ([470.4±2.7], [494.3±2.9], [512.3±5.7] mm, respectively) (P<0.05). At 6 weeks, there were more mRNA expressions of Notch-3, Jagged-1 and Delta-like-1 in solid diet group than in power diet group (P<0.05). The Notch-1 protein could be found in all layers of condylar cartilage, especially in the surface of hypertrophic zone. The expressions of Notch-1, Notch-3, and Delta-like-1 protein were increased from 2 to 6 weeks, and decreased at 8 weeks. In solid diet groups, the protein expressions of Notch-1 (at 2, 4, 6, 8 weeks), Notch-3 (at 2, 4, 6 weeks), Jagged-1 (at 2, 4, 6 weeks) and Delta-like-1 (at 4, 6, 8 weeks) were greater than in power diet groups (P<0.05). Conclusions: Low masticatory loading may delay or inhibit the development of condylar cartilage and its growing factors such as Notch-1, Notch-3, Jagged-1 and Delta-like-1. Appropriate masticatory loading plays an important role in normal development of the condyle.

Abstract
Cyclooxygenase (COX)-2 is upregulated in hepatocellular carcinoma (HCC). However, the direct causative effect of COX-2 in spontaneous HCC formation remains unknown. We thus investigate the role and molecular pathogenesis of COX-2 in HCC by using liver-specific COX-2 transgenic (TG) mice. We found spontaneous HCC formation with elevated inflammatory infiltrates and neovessels in male TG mice (3/21, 14.3%), but not in any of male WT mice (0/19). Reduced representation bisulfite sequencing (RRBS) and gene expression microarrays were performed in the HCC tumor and non-HCC liver tissues to investigate the molecular mechanisms of COX-2-driven HCC. By RRBS, DNA promoter hypermethylation was identified in HCC from TG mice. Induction of promoter hypermethylation was associated with reduced tet methylcytosine dioxygenase 1 (TET1) expression by COX-2. TET1 could catalyze the conversion of 5-methylcytosine into 5-hydroxymethylcytosine (5hmC) and prevents DNA hypermethylation. In keeping with this, loss of 5hmC was demonstrated in COX-2-induced HCC. Consistently, COX-2 overexpression in human HCC cell lines could reduce both TET1 expression and 5hmc levels. Integrative analyses of DNA methylation and gene expression profiles further identified significantly downregulated genes including LTBP1, ADCY5 and PRKCZ by promoter methylation in COX-2-induced HCC. Reduced expression of LTBP1, ADCY5 and PRKCZ by promoter hypermethylation was further validated in human HCCs. Bio-functional investigation revealed that LTBP1 inhibited cell proliferation in HCC cell lines, suggesting its potential role as a tumor suppressor in HCC. Gene expression microarrays revealed that signaling cascades (AKT (protein kinase B), STK33 (Serine/Threonine kinase 33) and MTOR (mechanistic target of rapamycin) pathways) were enriched in COX-2-induced HCC. In conclusion, this study demonstrated for the first time that enhanced COX-2 expression in hepatocytes is sufficient to induce HCC through inducing promoter hypermethylation by reducing TET1, silencing tumor-suppressive genes and activating key oncogenic pathways. Inhibition of COX-2 represents a mechanism-based target for HCC prevention.

Abstract
OBJECTIVE To investigate whether hypoxia microenvironment induced hepatocellular carcinoma cells SMMC-7721 epithelial-mesenchymal transition (EMT) and to explore the underlying molecular mechanism. MATERIALS AND METHODS In this study, SMMC-7721 cells were cultured under normoxia and hypoxia conditions, respectively. RT-PCR and Western blot were used to monitor the expression level of EMT-related markers, E-cadherin, and vimentin, as well as hypoxia inducible factor-1α (HIF-1α) and Twist1. Then we performed the transwell invasion assays to detect the ability of cell invasion. RESULTS The results demonstrated that hypoxia micro-environment could induce hepatocellular carcinoma cells SMMC-7721 EMT and enhance the cell invasion ability. Furthermore, knockdown of Twist1 by using specific siRNA could reverse hypoxia-induced EMT process. CONCLUSIONS Hypoxia promotes hepatocellular carcinoma cells SMMC-7721 EMT by upregulating the expression of Twist1.

Abstract
Exfoliative cytology is a simple and non-invasive examination method that is easily accepted by the patient. A number of new techniques are used to further increase the accuracy of sample collecting. It is widely used in the detection of cervical, oral cavity and various coelom exfoliated cells. This article reviews the development of exfoliative cytology in oral cancer diagnosis. It is realized that the qualitative and quantitative analysis of cancer and precancerous lesions, through DNA quantitative analysis to calculate DNA index (DI value), multiple parameter analysis and statistical modeling calculation to evaluate oral cancer risk index (OCRI) of the patient has great significance in cancer screening, early diagnosis and prognosis review, especially in the field of oral cancer.

Abstract
We have investigated experimentally and numerically the temperature and refractive index (RI) sensitivity characteristics of excessively tilted fiber gratings (Ex-TFGs) in detail. Both results have shown that the temperature and RI sensitivities of Ex-TFGs are mode order dependent. For temperature sensitivity, the higher order cladding mode of Ex-TFG exhibited lower temperature sensitivity, quantitatively, the temperature sensitivities of TM cladding modes at the resonance wavelength around 1550nm are 9pm/°C, 6.8pm/°C, 5.6pm/°C and, 4pm/°C for cladding mode 28th, 31st, 35th, 40th, respectively, indicating the overall temperature sensitivity of Ex-TFGs were lower than that of normal FBGs. The SRI sensing results have shown that the RI sensitivity of Ex-TFG at the special index value could be improved by choosing the cladding mode with effective index close to the refractive index of the detecting medium. The SRI sensitivities at the effective mode index were 2250nm/RIU at 1.408, 864nm/RIU at 1.395, 1536nm/RIU at 1.380 and 1360nm/RIU at 1.355, for the cladding mode of 28th, 31st, 35th, 43rd, respectively. The experimental results have also shown the SRI sensitivity of Ex-TFG was increasing with increasing of the resonance wavelength.

Abstract
Abstract
Background
Young breast cancer (BC) patients often face the disease before completing their family planning. The best available retrospective evidence suggests that pregnancy after BC does not negatively impact disease outcomes in patients with endocrine-responsive BC and is safe for offspring. However, given the possibility of prolonged adjuvant endocrine therapy (ET) (5-10 yrs), it is not feasible to wait until completion of therapy in many of these women and thus there is a need to explore the safety of temporary interruption of ET to allow pregnancy. To date, no prospective study has been conducted in young women attempting future pregnancy.
Trial Design
Young patients with endocrine-responsive early BC and pregnancy desire will interrupt ET for up to 2 yrs to attempt pregnancy. As resumption of menses and conception depends on many factors, e.g. patient's age and adjuvant treatment received, the 2-yr interruption period is approximate, intended to include treatment wash-out (3 mos) conception (∼3-6 mos), delivery (∼9 mos), breast feeding (∼6 mos). Patients will be strongly advised to resume ET as soon as pregnancy attempts are concluded and to complete the planned 5-10 yrs ET.
Major Eligibility Criteria
* Histologically-proven stage I-III endocrine-responsive BC.
* Age ≥ 18 and ≤ 42 years at enrollment.
* Adjuvant ET (SERM alone, GnRH analogue plus SERM or AI) for ≥18 mos but ≤30 mos, stopped within 1 mo prior to enrollment.
* Patient wishes to become pregnant.
* Premenopausal status at BC diagnosis.
Specific Aim
To assess the risk of BC relapse associated with temporary interruption of ET to permit pregnancy and to evaluate pregnancy success and offspring outcome.
Statistical Methods
A true risk of BC recurrence of 2% per year is assumed for patients who do not interrupt ET. With 500 patients enrolled in 4.0 yrs and an additional 1.6 yrs of follow up, there will be approximately 1600 patient-yrs of follow up and a median follow up of approximately 3 yrs at the time of the primary analysis, anticipated to occur 5.6 yrs after enrolment of the first patient. If the true risk of BC recurrence is 2% per yr, we anticipate 31 BC recurrences and an estimated 3-yr breast cancer free interval (BCFI) event of 5.6% (95% CI 4.0% to 7.9%).
Translational Research will investigate different ovarian function and uterine parameters; and circulating tumour DNA. FFPE tissue of the primary tumour will be collected to integrate different parameters related to biology of BC arising in young women. All material will be banked centrally.

Abstract
Abstract
Background
Longer chemotherapy (CT) duration is associated with a significant improvement in progression-free survival (PFS) and a moderate, but significant improvement in overall survival (OS) in MBC patients (pts). Prolonged CT administration, however, must be weighed against the side effects of continuous CT delivery. The SNAP trial was designed to improve the tolerability of prolonged CT by studying alternative treatment schedules.
Methods
The SNAP trial enrolled 258 women from April 2013 to Aug 2015. Eligibility criteria included HER2- MBC, no prior CT for advanced disease, measurable and/or non-measurable disease.
All eligible pts were randomized to one of three arms. Pts received the same induction chemotherapy consisting of 3 cycles of nab-Paclitaxel given days 1,8,15 Q28, followed by one of the three maintenance therapy schedules. Originally, the dose of the induction chemotherapy was 150 mg/m2, but this was reduced to 125 mg/m2 following the first safety review of 48 treated pts. The three schedules of nab-Paclitaxel used as maintenance therapy were (Arm A) nab-Paclitaxel 150 mg/m2 d 1,15 Q28; (Arm B) nab-Paclitaxel 100 mg/m2 d 1,8,15 Q28; (Arm C) nab-Paclitaxel 75 mg/m2 d 1,8,15,22 Q28.
The primary objective is to evaluate the efficacy of three nab-Paclitaxel regimens as measured by progression-free survival (PFS), using the historical reference of PFS (based on AVADO study) of docetaxel for first-line treatment of metastatic breast cancer. Each of the three regimens is compared to the historic 7-month median PFS to determine whether any of the three regimens are worthy of further investigation. Secondary endpoints include tolerability, feasibility, response rate, OS and QoL.
Results
Two-hundred-fifty-eight pts have been randomised and 255 are available for primary endpoint evaluation. At 18.2 months' median follow-up, 182 PFS events and 85 deaths have been observed. Median PFS was 7.9 months (90%CI 6.8-8.4) in Arm A, 9.0 months (90%CI 8.1-10.9) in Arm B and 8.5 (90%CI 6.7-9.5) in Arm C. PFS in Arm B was significantly longer than the historic PFS of first-line docetaxel (one-sided log-rank p=0.03).
As expected, neurotoxicity was the most frequent adverse event. In the induction phase, grade≥2 sensory neuropathy was reported in 14.8% of pts at the starting dose of 150 mg/m2 and 7.5% at the starting dose of 125 mg/m2; grade≥3 sensory neuropathy occurred in 2.5% and 0% of the pts, respectively. In the maintenance phase, grade≥2 sensory neuropathy was reported in 37.9% of pts in Arm A, 36.1% in Arm B and 31.2% in Arm C; grade≥3 sensory neuropathy occurred in 9.1%, 5.6% and 6.6% of the pts, respectively.
199 pts started the maintenance phase. The median number of maintenance cycles was 3, 4, and 5, respectively. Stopping maintenance for reasons other than objective progression occurred in 41%, 58%, and 53%, respectively.
Conclusion
The SNAP trial indicates that alternative maintenance chemotherapy schedules with reduced doses after a short term induction phase at conventional doses are feasible and significantly more active than the historical PFS of docetaxel in the first line treatment of advanced breast cancer.

Abstract
Previous investigations demonstrated that high fluoride (F) exposure may adversely affect the neurodevelopment and learning and memory ability. However, whether maternal F exposure during gestation and lactation can influence the learning, memory ability, and glutamate receptor expressions of offspring has not yet been elucidated. Hence, in the present study, maternal mice were exposed to F (25, 50, or 100 mg/L sodium fluoride (NaF) in drinking water) during gestation and lactation. Results showed that exposure to 100 mg/L NaF significantly enhanced the number of total arm entries and working memory errors of offspring in the radial arm maze test compared to the control group. However, no difference was observed in open-field behaviors. For the subtypes of glutamate receptors in hippocampus, expression of GluR2 mRNA was significantly reduced by 25, 50, and 100 mg/L NaF. Besides, F exposure also suppressed the expression of NR2A, NR2B, and mGluR2 mRNA levels in a dose-dependent manner, where NR2A was significantly suppressed by 50 mg/L NaF and NR2B and mGluR2 by 100 mg/L NaF. However, no significant changes were observed in GluR1 and mGluR5 mRNA expression levels. Collectively, these findings suggested that F can pass through the cord blood and breast milk and may have deleterious impact on learning and memory of the mouse pups, which was mediated by reduced mRNA expression of glutamate receptor subunits.

Abstract
The immune system can be damaged by chronic stress. However, for this process, the involved molecular alterations and their regulatory roles played in immunosuppression still remain unclear. This study was aimed to identify the differences in serum protein expressions that are closely associated with the effect of chronic stress on immune function. Serum protein levels of rats in control group and chronic stress group were measured by iTRAQ analysis. Subsequently, among the 121 differentially expressed proteins screened between the two groups, 46 proteins were upregulated (>1.5-fold, P < 0.05), while 75 proteins were downregulated (<0.67-fold, P < 0.05). Bioinformatics analysis revealed that most of the differentially expressed proteins were in relation with the metabolic, cellular, response stimulus and immune system processes. The significantly differential expression of ceruloplasmin, haptoglobin, catalase and peroxiredoxin-1 were picked out for reconfirmation by ELISA analysis. The results were consistent with those obtained by iTRAQ. What is more, the roles of above-mentioned four proteins, apolipoprotein B-100 and heat-shock protein 90 in immunosuppression induced by chronic stress were discussed. Taken together, these findings may provide a new insight into better understanding the molecular mechanisms of immunosuppression induced by chronic stress.

Abstract
We present the first measurement of charge-dependent directed flow in Cu+Au collisions at sqrt[s_{NN}]=200 GeV. The results are presented as a function of the particle transverse momentum and pseudorapidity for different centralities. A finite difference between the directed flow of positive and negative charged particles is observed that qualitatively agrees with the expectations from the effects of the initial strong electric field between two colliding ions with different nuclear charges. The measured difference in directed flow is much smaller than that obtained from the parton-hadron-string-dynamics model, which suggests that most of the electric charges, i.e., quarks and antiquarks, have not yet been created during the lifetime of the strong electric field, which is of the order of, or less than, 1 fm/c.

Abstract
BACKGROUND Although both obesity and hypertension are known risk factors for disability, the joint association of obesity and hypertension with risk of disability is unknown. This paper is aim to examine the joint association of obesity and hypertension with risk of disability. METHODS Cross-sectional study with 8060 elderly community-dwelling individuals participating in the survey initiated by Shanghai Health and Family Planning Commission from March to September 2013. Obesity was measured using the body mass index (BMI) in World Health Organization (WHO) Asia criteria. Hypertension, based on the doctor's diagnosis, was obtained through face-to-face interview. Disability was measured using the self-reported physical self-maintenance scale (PSMS) and the instrumental activities of daily living (IADL) scale developed by Lawton and Brody. RESULTS A total of 8.97% of participants reported ADL disability, and 15.18% for IADL disability. After adjusting social demographics and chronic conditions, the risk of ADL disability was progressively greater in obese persons with hypertension (OR=1.40, 95% CI=1.05-1.89), underweight persons without hypertension (OR=2.05, 95% CI=1.29-3.25), and underweight persons with hypertension (OR=2.14, 95% CI=1.36-3.36). For IADL disability, only underweight persons with hypertension were significantly associated (OR=1.65, 95% CI=1.23-2.21). CONCLUSIONS Low or extremely high BMI, independent of its metabolic consequences, is a risk factor for disability among the elderly. Simple hypertension wasn't significantly associated with disability. In addition, having hypertension significantly increased the risk of ADL disability in obese individuals and IADL disability in underweight individuals.

Abstract
Tai chi exercise may have positive effects on bone health in perimenopausal and postmenopausal women. This systematic review is the first to summarize evidence to clarify the efficacy of tai chi exercise in bone health. The benefits of tai chi exercise on bone health remain unclear; further studies are needed. Emerging randomized controlled trials (RCTs) exploring the efficacy of tai chi exercise on bone health among older women, but yielded inconclusive results. Our objective is to conduct a systematic review to evaluate evidence from RCTs to clarify the efficacy of tai chi exercise on bone mineral density (BMD), and bone turnover markers (BTM) in perimenopausal and postmenopausal women. Six electronic databases were searched, and reference lists of systematic reviews and identified studies from the search strategy were also screened. We included all RCTs that investigate tai chi exercise for bone health in perimenopausal and postmenopausal women. Data selection, extraction, and evaluation of risk of bias were performed independently by two reviewers. Ten trials detailed in 11 articles were included. Six of the 11 studies reported positive outcomes on bone health. Results of our meta-analysis showed a significant effect of tai chi exercise on BMD change at the spine compared with no treatment in perimenopausal and postmenopausal women. When tai chi exercise combined with a calcium supplement was compared with the calcium supplement alone, the result of BMD change at the spine showed no significant effect. Because the measurable effect observed was minimal, and due to the low quality of methodology of the studies, we conclude that the result is of limited reliability. Tai chi exercise may have benefits on bone health in perimenopausal and postmenopausal women, but the evidence is sometimes weak, poor, and inconsistent. Consequently, only limited conclusions can be drawn regarding the efficacy of tai chi exercise on bone health. Further well designed studies with low risk of bias are needed.

Abstract
BACKGROUND AND AIM This study was conducted to determine 25-hydroxyvitamin D [25(OH) D] levels in serum, and to investigate their associations with stroke recurrence events in a 3-month follow-up study in Chinese patients with first-ever ischemic stroke. METHODS AND RESULTS From February 2014 to September 2015, consecutive first-ever ischemic stroke patients admitted to the Department of Emergency of our hospital were identified. Serum 25(OH) D levels were measured at admission. We followed the participants for a median of 3 months (range, 2.5-3.5 months) using a standard questionnaire. We used logistic regression models to assess the relationship between 25(OH) levels and risk of recurrent stroke. In this study, 349 ischemic stroke patients were included and completed follow-up. Thirty-seven patients (10.6%) had a stroke recurrence. Serum 25(OH) D levels in patients with recurrent stroke were significantly lower as compared with those in patients without recurrent stroke [9.9 (IQR, 7.9-14.8) ng/mL vs. 17.9 (IQR, 13.4-23.4) ng/mL; P < 0.001). After adjusting for traditional risk factors, serum 25(OH) D levels were negatively associated with the stroke recurrence (OR, 0.897; 95% CI, 0.848-0.950; P < 0.001). Compared with the first quartile of serum 25(OH) D levels, the second quartile OR for recurrent stroke was 0.466 (95% CI, 0.308-707; P = 0.006). For the third and fourth quartiles, it was 0.248 (95% CI, 0.100-0.618; P = 0.001) and 0.173 (95% CI, 0.062-0.482; P < 0.001), respectively. CONCLUSIONS Our findings suggest that reduced serum levels of 25(OH) D can predict the risk of early stroke recurrence in patients with first-ever ischemic stroke.

Abstract
Pecan (Carya illinoensis) has been introduced to East China for over one hundred years, but its planting is still only occurring at a small scale. The key limiting factor is its low yield. To enhance the yield pecan in East China, two pecan cultivars, Mahan and Western, were examined. Twenty traits describing phasic development, yield, nut quality, and cultural practice were investigated. We found that pecan cultivar Mahan gives a higher yield and nut quality than cultivar Western. We recommend interplanting of cultivar Pawnee to act as a pollinator tree. Appropriate cultivation practices that can be implemented to enhance fruit yield of cultivars Mahan and Western include soil-applied paclobutrazol (PBZ) at certain concentrations, pinching, and supplementary pollination. For example, the addition of 1.25 g/m2 of PBZ inhibits pecan branch growth and stimulates short bearing branches, which promotes fruit yield. We found that soil-applied PBZ reached optimal performance 82 days after application. A pinching length of 40 cm resulted in a fruit yield increase. In addition, grafting and transplantation may promote male flowering, but delays female flowering. These cultural practices may provide insights that can be used to improve pecan cultivation in East China.

Abstract
OBJECTIVE To investigate the influence of maxillary impacted canines on the root morphology of adjacent premolars in a Chinese population. SUBJECTS AND METHODS A sample of 370 Chinese subjects with maxillary canine impaction and 370 control subjects were collected in this study. CBCT data of all subjects were collected and analyzed. The prevalence of separate-rooted maxillary premolars was compared between subjects with and without impacted canines. Then, the prevalence of separate-rooted maxillary premolars was compared between subjects with buccal canine impaction (BIC) and those with palatal impaction (PIC). RESULTS The prevalence of separate-rooted first premolars was significantly higher in the canine impaction group (P = 0.046), but the prevalence of separate-rooted second premolars was not different (P = 0.780). Furthermore, a significant higher prevalence of first premolar root separation was found on the impacted site in the BIC subgroup (P < 0.001), but not in the PIC subgroup (P = 0.508). Also, the prevalence of separate-rooted first premolars in the BIC subgroup was significantly higher than that of the control group (P = 0.008), but not so for the PIC subgroup (P = 0.097). CONCLUSIONS Buccally impacted maxillary canines are associated with an increased prevalence of root separation in the adjacent maxillary first premolars. This is likely because that buccally impacted canines encroach on the space needed for root development of the first premolars.

Abstract
OBJECTIVES To review the advances and limitations of recent investigations on mandibular distraction osteogenesis (MDO) assisted by mesenchymal stem cell (MSC) transplantation. MATERIALS AND METHODS Following the preferred reporting items for systematic reviews and meta-analysis (PRISMA) guidelines, the PubMed, Scopus, and Cochrane electronic databases were systematically searched and screened from their inception through August 2014. Searching terms included the following: 'distraction osteogenesis', 'mandible OR mandibular OR jaw', and 'cells', without any other limitations. RESULTS Nineteen studies meeting the eligibility criteria were selected from 227 published articles and used for qualitative synthesis. Fifteen of the studies used small animal models (rats or rabbits), while the other four used large animal models (dogs, pigs or sheep). Among these studies, large variations exist in MDO protocol, cell transplantation time, route and quantity, as well as methodology of outcome assessment. Additionally, all studies had certain biases. Nevertheless, the majority of studies found that MSC transplantation enhanced MDO bone regeneration. CONCLUSION Evidence from animal studies indicates that MDO may be enhanced by mesenchymal stem cell transplantation, but many questions related to animal models, MDO protocols, and cell transplantation remain to be investigated.
