Abstract
AIM Azathioprine can prevent postoperative recurrences in Crohn's disease. We compared the efficacy of azathioprine in preventing surgical recurrence to explore whether immediate prophylaxis after surgery is better than azathioprine started after endoscopic or clinical recurrence. METHOD Data of patients with intestinal resection and ileocolic anastomosis for Crohn's disease between 2006 and 2015 were retrieved from a prospectively maintained database. Patients were grouped according to the strategies of postoperative therapy with azathioprine. Univariate and multivariate proportional hazard Cox regression analyses were conducted to identify independent predictive factors for surgical recurrence. RESULTS Only age equal to or less than 16 years at diagnosis was an independent risk factor for surgical recurrence in all 166 patients (P = 0.005). In patients with high risk of recurrence (27 in the symptom-driven group, 39 in the endoscopy-driven group and 69 in the immediate prophylaxis group), both immediate and endoscopy-driven azathioprine delayed and reduced surgical recurrence compared with symptom-driven azathioprine (P = 0.035, 0.019). Their efficacy in reducing surgical recurrence was confirmed by Cox regression analyses (hazard ratio 0.465, P = 0.045; hazard ratio 0.352, P = 0.028). Surgical recurrence was similar between the immediate and endoscopy-driven groups. In addition, age ≤ 16 at diagnosis was still an independent risk factor for surgical recurrence in this subgroup. CONCLUSIONS In patients with high risk of recurrence, both immediate prophylactic azathioprine after surgery and azathioprine started after endoscopic recurrence can delay and reduce surgical recurrence compared with azathioprine started after clinical recurrence. In addition, azathioprine started immediately after surgery was not superior to azathioprine started after discovery of endoscopic recurrence.

Abstract
Essentials Microbe-dependent production of trimethylamine N-oxide (TMAO) contributes to thrombosis risk. The impact of host flavin monooxygenase 3 (FMO3) modulation on platelet function is unknown. Genetic manipulation of FMO3 in mice alters systemic TMAO levels and thrombosis potential. Genetic manipulation of FMO3 is associated with alteration of gut microbial community structure. SUMMARY Background Gut microbes play a critical role in the production of trimethylamine N-oxide (TMAO), an atherogenic metabolite that impacts platelet responsiveness and thrombosis potential. Involving both microbe and host enzymatic machinery, TMAO generation utilizes a metaorganismal pathway, beginning with ingestion of trimethylamine (TMA)-containing dietary nutrients such as choline, phosphatidylcholine and carnitine, which are abundant in a Western diet. Gut microbial TMA lyases use these nutrients as substrates to produce TMA, which upon delivery to the liver via the portal circulation, is converted into TMAO by host hepatic flavin monooxygenases (FMOs). Gut microbial production of TMA is rate limiting in the metaorganismal TMAO pathway because hepatic FMO activity is typically in excess. Objectives FMO3 is the major FMO responsible for host generation of TMAO; however, a role for FMO3 in altering platelet responsiveness and thrombosis potential in vivo has not yet been explored. Methods The impact of FMO3 suppression (antisense oligonucleotide-targeting) and overexpression (as transgene) on plasma TMAO levels, platelet responsiveness and thrombosis potential was examined using a murine FeCl3 -induced carotid artery injury model. Cecal microbial composition was examined using 16S analyses. Results Modulation of FMO3 directly impacts systemic TMAO levels, platelet responsiveness and rate of thrombus formation in vivo. Microbial composition analyses reveal taxa whose proportions are associated with both plasma TMAO levels and in vivo thrombosis potential. Conclusions The present studies demonstrate that host hepatic FMO3, the terminal step in the metaorganismal TMAO pathway, participates in diet-dependent and gut microbiota-dependent changes in both platelet responsiveness and thrombosis potential in vivo.

Abstract
PURPOSE The survival benefit from detecting additional breast cancers by preoperative magnetic resonance imaging (MRI) continues to be controversial. METHODS We followed a cohort of 4454 women diagnosed with non-metastatic breast cancer (stage I-III) from 2/2005-6/2010 in five registries of the breast cancer surveillance consortium (BCSC). BCSC clinical and registry data were linked to Medicare claims and enrollment data. We estimated the cumulative probability of breast cancer-specific and all-cause mortality. We tested the association of preoperative MRI with all-cause mortality using a Cox proportional hazards model. RESULTS 917 (20.6%) women underwent preoperative MRI. No significant difference in the cumulative probability of breast cancer-specific mortality was found. We observed no significant difference in the hazard of all-cause mortality during the follow-up period after adjusting for sociodemographic and clinical factors among women with MRI (HR 0.90; 95% CI 0.72-1.12) compared to those without MRI. CONCLUSION Our findings of no breast cancer-specific or all-cause mortality benefit supplement prior results that indicate a lack of improvement in surgical outcomes associated with use of preoperative MRI. In combination with other reports, the results of this analysis highlight the importance of exploring the benefit of preoperative MRI in patient-reported outcomes such as women's decision quality and confidence levels with decisions involving treatment choices.

Abstract
Abstract
This study examined whether breast density is associated with risk of breast cancer in women age ≥65 years undergoing screening mammography in community practice. Methods: We used prospective cohort data between 1996 and 2012 from the Breast Cancer Surveillance Consortium (BCSC). We calculated separate cumulative incidence models for breast cancer incidence according to Breast Imaging Reporting and Data System (BI-RADS) breast density for women ages 65–74 and ages ≥75. Multivariable Cox proportional hazards regression models were fitted to determine the risk of invasive breast cancer adjusted for BCSC registry, race/ethnicity, BMI, hormone therapy use and benign breast disease. Results: Among the 403,268 women included in the study, approximately 40% were ages ≥75. The annual incidence rate of invasive breast cancer increased with increasing breast density among women ages 65–74 [BI- RADS fatty breasts: 2.2% (95% CI, 2.1%–2.4%) vs. heterogeneously or extremely dense breasts: 4.7% (95% CI, 4.6%–4.9%)] and women ages 75+ [BI-RADS fatty breasts: 2.3% (95% CI, 2.1%–2.5%) vs. heterogeneously or extremely dense: 4.3% (95% CI, 4.1%–4.5%)]. Women with BI-RADS fatty breasts had a decreased risk of breast cancer among women ages 65–74 [HR: 0.66 (95% CI: 0.58%–0.78%) and women ages ≥75 [HR: 0.73 (95% CI: 0.62%–0.87%). Women with BI-RADS heterogeneously or extremely dense breasts were found to have increased risk of breast cancer among women ages 65–74 [HR: 1.39 (95% CI: 1.28%–1.51%)] and women ages ≥75 [HR: 1.23 (95% CI: 1.10%–1.37%)]. Conclusions: Older women with higher BI-RADS density had a significantly increased risk of breast cancer. These findings add further evidence that breast density continues to be associated with an increased risk of breast cancer, even among women age ≥75 years.

Abstract
In this paper, we introduce a combustion method which is rapid, low cost, mass-producing and environmentally friendly to produce nanoporous graphene. After loading a graphene oxide aerogel (GOA)/paper (GOP) on a preheated hot plate (as the heat source, with a temperature as low as 200 °C) under an ambient environment, in a few seconds, the GOA/GOP would self-combust and change into reduced graphene oxide (RGO) with nanopores mainly concentrated in the 0.4-2.0 nm range and a large specific surface area of 536 m2 g-1. Supercapacitors fabricated with the synthesized porous RGO (P-RGO) showed a high specific capacitance of 245 F g-1 at 0.1 A g-1, and a retention rate of about 96.9% after 12 000 cycle tests with respect to the initial specific capacitance with a scan rate of 10.0 A g-1. The production yield of this method was as high as 77.0%.

Abstract
Abstract
To investigate the characteristics of somatic mutation or copy number variations in Chinese breast cancer, tumor tissues from 105 patients diagnosed at age from 26 to 81 (median age 48) were assessed by next-generation sequencing technology using a customized panel, including 33 genes of putative tumor suppressors or oncogenes. At least one genetic alteration (including mutations, copy number variations and fusion genes) was observed in 99/105 (94%) samples. Similar to the previous report in TCGA dataset, TP53 (49%) and PIK3CA (43%) were the most frequently mutated genes, which occurred in a significant mutual exclusive manner (p<0.05). Three genes including MYC copy number amplification (35%), FGFR1 (19%) and GATA3 mutation (16%) were altered at the frequency of >10% in our dataset, in which the occurrence of MYC amplification was higher than the TCGA cohort (22%, p<0.05). Importantly, we identified four fusion genes of FGFR1 including one previously reported (TACC1-FGFR1) and three novel fusion ones (MIR1268A-FGFR1, LZTS1-AS1-FGFR1, and LINC01605-FGFR1). Unlike the high prevalence of CCND1 amplification (17%) and CDH1 mutations (13%) in TCGA dataset, genetic variations of CCND1 and CDH1 in our study occurred at a low frequency with 2% and 4%, respectively (p<0.05). In addition, we also identified three novel ESR1 mutations (ESR1 G74R, D230H and M250T) in the untreated patients with early breast cancer. Furthermore, nonnegative matrix factorization (NMF) clustering of genetic variations revealed five distinct molecular classes in our dataset. NMF class I was characterized by a high rate of HR+/ERBB2- tumors (80%) and genetic alterations of FGFR1 (100%). A gain of ERBB2 gene was observed in 93% of NMF class II along with TOP2A amplification in 57% of HR+/ERBB2+ tumors. NMF class III was characterized by a high rate of HR+/ERBB2- (95%) and GATA3 mutations (75%) without TP53 mutation. The characteristics of NMF class IV were the high rate of PIK3CA mutations (95%) and HR+/ERBB2- tumors (75%) along with low rate of TP53 mutations. More HR-/ERBB2- tumors (39%) were observed in NMF class V with a high rate of MYC amplification (82%) and TP53 mutation (89%). Further analysis in the TCGA cohort revealed the patients in NMF class V had the shorter survival time than other clusters. Collectively, we identified several novel genetic variations and generated a preliminary profile of somatic genetic aberrations that could classify Chinese breast cancer in this study, and may represent novel therapeutic targets for molecular subsets of breast cancer.

Abstract
Abstract
Background: Eribulin mesylate, a microtubule inhibitor, is approved in the US for the treatment of patients (pts) with metastatic breast cancer (MBC) who have previously received at least 2 chemotherapeutic regimens for the treatment of metastatic disease, including an anthracycline and a taxane. The recommended dose is 1.4 mg/m2 (equivalent to 1.23 mg/m2 eribulin [expressed as free base]) on day (D) 1 and D8 of a 21-D cycle. However, this schedule can result in dose delays and reductions due to myelosuppression. A dosing regimen of eribulin (1.4 mg/m2) administered intravenously (IV) biweekly (Q2W; on D1 and D15) in 28-D cycles was evaluated with the intent of improving eribulin's safety profile without compromising efficacy.
Methods: Female pts with human epidermal growth factor receptor (HER)2-negative MBC, who had received 2-5 prior chemotherapy regimens and had ECOG PS ≤2 were enrolled in 12 sites in the US. Prophylactic granulocyte colony-stimulating factor (G-CSF) was not allowed. If neutropenia occurred, growth factors were used during eribulin treatment at the physician's discretion. Primary endpoints were objective response rate (ORR) and disease control rate (DCR). Secondary endpoints were progression-free survival (PFS), overall survival (OS), dose intensity (measured by feasibility rate), safety and tolerability.
Results: Median age of the 58 enrolled pts was 64 yrs (range: 38-85). The majority of pts (93%) had ECOG PS ≤1, and 12% of pts had triple-negative MBC. Number of prior chemotherapeutic regimens: 2 (17% of patients), 3 (24%), 4 (27%), and 5 (31%). 76% Of pts had visceral disease and 86% had previous taxane therapy. ORR (95% confidence interval [CI]) was 12% (5-24), DCR (CR+PR+SD) was 65% (95% CI: 51-77), and CBR (CR+PR+SD ≥23 weeks) was 30% (95% CI: 18-43) [n=57]. Median PFS (95% CI) was 3.6 mo (2.9-4.1). Median OS (95% CI) was 13.2 mo (10.6-not estimable). 6-Month and 12-month OS rates were 84% and 54%, respectively. Dose intensity measured by the feasibility rate (defined as the percentage of pts completing the first 2 and 4 cycles without a dose delay >5 days or dose reduction due to an adverse event [AE]) was 70% and 46%, respectively.
The most frequent AEs (all grades) were neutropenia (69%), fatigue (48%), alopecia (45%), and constipation (36%). 22% Of pts had grade (G) 1 alopecia and 22% of pts had G2 alopecia. 72% Of pts had G3/4 AEs: neutropenia, 57%, and peripheral neuropathy, 12%. G3 peripheral sensory neuropathy occurred in 9% of pts, with no G4 incidence. There were 2 deaths (1 sepsis, 1 acute respiratory failure), which were considered not related to treatment. 50% (29/58) Of all patients received at least 1 dose of growth factor and 70% (28/40) of patients with neutropenia received growth-factor support.
Conclusions: Tumor response rates and OS of this treatment schedule in a heavily pretreated patient population were similar compared to previously reported phase 3 studies of eribulin. The toxicities associated with biweekly eribulin were manageable.

Abstract
Abstract
Reduction of selenium-binding protein 1 (SELENBP1) has been frequently observed in various solid tumors, and associated with poor clinical prognosis, implicating SELENBP1 as a potential tumor suppressor. However, the molecular mechanism underlying the transcriptional regulation of SELENBP1 remains poorly understood. In this study, we first analyzed the relationship between SELENBP1 mRNA levels and clinical or pathological features of breast cancer in METABRIC datasets, and found that SELENBP1 mRNA levels were differentially expressed in PAM50 molecular subtypes with highest levels in Luminal A/B subtype and lowest levels in Basal-like/Claudin-low subtype, indicating that SELENBP1 might function as the downstream player of estrogen receptor α (ERα). Following the adjustment of clinicopathological characteristics including the menopausal status, ER/HR/ERBB2 status, TNM stage and histological grade, the Kaplan-Meier survival analysis surprisingly showed that patients with higher levels of SELENBP1 mRNA (n=43) had shorter survival time than those with moderate levels of SELENBP1 expression (n=102) in Luminal A subtype (Hazard Ratio 1.59; 95% CI 0.99-2.54; Logrank p=0.0367), although the patients with lower SELENBP1 levels were consistent the poor prognosis in Basal-like/Claudin-low subtype (Hazard Ratio 1.54; 95% CI 0.97-2.44; Logrank p=0.0356). To elucidate this controversy, we knocked down the expression of ERα in MCF-7 cells using shRNA targeting ERα, and found that knockdown of ERα resulted in the down-regulation of mRNA and protein expression of SELENBP1. In addition, SELENBP1 promoter-driven luciferase reporter assay reveled ERα regulated the expression of SELENBP1 at transcriptional level. Interestingly, we further found that the addition of 4-hydroxytamoxifen (4-OHT) led to a dramatic reduction of SELENBP1 protein expression in MCF-7 cells, while forced expression of SELENBP1 in MCF-7 cells significantly enhanced 4-OHT-mediated inhibition of anchor-independent cancer cell growth. Collectively, these results suggested that the transcriptional induction of SELENBP1 by ERα might function as a downstream tumor suppressor in breast cancer cells, but endocrine therapy led to the down-regulation of SELENBP1 expression due to the blocking of ERα signaling in the patients with Luminal subtype, which was likely to explain the observation of differential predictive value for SELENBP1 mRNA levels in the Luminal and Basal-like/Claudin-low subtypes. Further investigation in vitro and in vivo has been ongoing in our laboratory, and the results from which will help us better understand the clinical relevance for SELENBP1 as a promising therapeutic target in improving the efficacy of endocrine therapy.

Abstract
Abstract
Emerging evidence has revealed that the mutations in estrogen receptor alpha (ERα) gene (ESR1) is frequently observed in ER+ metastatic breast cancer, and is associated with the aggressively invasive and metastatic phenotype in advanced breast cancer due to the resistance of endocrine therapy. In our previous study, we have identified three novel mutations of ESR1, including ESR1 G74R, D230H and M250T, in the untreated patients with early breast cancer. However, the functional roles for these novel mutations in the cellular biology of breast cancer remain to be elucidated. In this study, we described the molecular mechanism underlying potential roles for the novel mutation ESR1 p.Met250Thr (c.749T>C) in regulating the cellular invasiveness of breast cancer. Firstly, we found, as compared with wild-type (WT) HA-ESR1, forced expression of HA-ESR1 M250T enhanced the invasive capacity of breast cancer MCF-7 cells by using Transwell assay. Moreover, we found that the levels of miR-190 were significantly up-regulated in the MCF-7 (HA-ESR1 M250T) cells, and further verified that miR-190 played an important role in ESR1 M250T-mediated induction of cellular invasiveness by using specific shRNA to knock down miR-190 levels in MCF-7 (HA-ESR1 M250T) cells. Further bioinformatics analysis showed that there were several half Estrogen Response Elements (EREs) in the promoter region of Talin-2, as the host gene of miR-190. Talin-2-driven luciferase reporter assay indicated ESR1 M250T resulted in a higher increase in the luciferase activity than ESR1 WT. Chromatin-immunoprecipitation (ChIP) assay identified a higher binding ability with Talin-2 promoter for ESR1 M250T than ESR1 WT. Collectively, our mechanistic study revealed that the ESR1 M250T mutation, located in the DNA-binding domain, increased the invasive capacity of breast cancer cells via the transcriptional induction of Talin-2 and miR-190. The potential role for ESR1 M250T in affecting the efficacy of endocrine therapy has been under the investigation in our laboratory, and the result from which will help us better elucidate the clinical relevance for novel ESR1 mutations in affecting the sensitivity of endocrine therapy.

Abstract
This retrospective study investigated the efficiency of nutritional support in unresectable locally advanced oesophageal squamous cell carcinoma (LAOSCC) patients who received concurrent chemoradiotherapy (CCRT) based on 5-fluorouracil and cisplatin. In the routine care group, 63 patients served as historical controls and received nutrition support in a reactive manner. In addition, 57 patients in the nutritional support group received timely diet counselling, oral nutritional supplements, enteral nutrition and/or parenteral nutrition during CCRT. This support was based on scores from nutritional risk screening 2002 (NRS-2002) after June 2014. The nutritional support group had significant advantages over the routine care group with respect to the incidence of neutropenia, the objective response rate, the change in serum albumin and the lengths of hospital stay. In addition, the nutritional support group had significantly higher levels of IgG and IL-2, higher proportions of NK, CD3+ and CD4+ cells as well as a higher ratio of CD4+ /CD8+ cells than the routine care group (p < .05). In contrast, the nutritional support group had a significantly lower level of IL-6. In conclusion, the current nutritional care programme could bring benefits of improving treatment compliance, reducing toxicity and lengths of hospital stay and enhancing the immune response.

Abstract
We show that the topological index of a wave function, computed in the space of twisted boundary phases, is preserved under Hilbert space truncation, provided the truncated state remains normalizable. If truncation affects the boundary condition of the resulting state, the invariant index may acquire a different physical interpretation. If the index is symmetry protected, the truncation should preserve the protecting symmetry. We discuss implications of this invariance using paradigmatic integer and fractional Chern insulators, Z_{2} topological insulators, and spin-1 Affleck-Kennedy-Lieb-Tasaki and Heisenberg chains, as well as its relation with the notion of bulk entanglement. As a possible application, we propose a partial quantum tomography scheme from which the topological index of a generic multicomponent wave function can be extracted by measuring only a small subset of wave function components, equivalent to the measurement of a bulk entanglement topological index.

Abstract
Background The subcrestal placement of implant platform has been considered a key factor in the preservation of crestal bone, but the influence of implant placement depth on bone remodeling combined with peri-implantitis is not fully understood. The aim of this study was to assess the effect of the crestal or subcrestal placement of implants on peri-implant bone defects of ligature-induced peri-implantitis in dogs. Material and Methods Eight weeks after tooth extraction in six beagle dogs, two different types of implants (A: OsseoSpeed™, Astra, Mölndal, Sweden; B: Integra-CP™, Bicon, Boston, USA) were placed at either crestal or subcrestal (-1.5 mm) positions on one side of the mandible. Ligature-induced peri-implantitis was initiated four weeks after the installation of the healing abutment connections. After 12 weeks, tissue biopsies were processed for histological analyses. Results Supra-alveolar bone loss combined with a shallow infrabony defect was observed in crestal level implants while deep and wide infrabony defects were present in subcrestal level groups. Subcrestal groups showed significantly greater ridge loss, depths and widths of infrabony defects when compared to crestal groups (P<0.001). Conclusions Within the limitations of the animal study, it can be stated that the implants at subcrestal position displayed greater infra-osseous defect than implants at crestal position under an experimental ligature-induced peri-implantitis. Key words:Subcrestal, peri-implantitis, histology.

Abstract
The objectives of this study were to examine the clinical response, changes in ruminal bacterial microbiota, and inflammatory response in lamellar tissues during oligofructose-induced laminitis. Ten fistulated sheep were randomly assigned into a control group ( = 5) and a treatment group ( = 5). The treatment group was infused with oligofructose (21 g/kg BW) by rumen cannula, and the control group was sham-treated with saline. Results showed that all 5 sheep treated with oligofructose developed anorexia and diarrhea 8 to 12 h after the administration of oligofructose. By 12 to 24 h after treatment, the treatment group developed lameness and roach back. Compared with the control group, oligofructose administration decreased ( < 0.001) the rumen pH and concentrations of total VFA and increased ( < 0.001) the level of lactic acid in the rumen. Microbial data analysis revealed that oligofructose infusion increased the abundance of ( = 0.009) and ( = 0.008) and decreased the percentage of unclassified Christensenellaceae ( = 0.028), unclassified Ruminococcaceae ( = 0.009), ( = 0.016), unclassified Lachnospiraceae ( = 0.009), and ( = 0.009) compared with the control group. Oligofructose infusion decreased the ACE ( = 0.047) and Shannon ( = 0.009) indices compared with the control group. The histomorphology analysis revealed that oligofructose overload resulted in damage to the dermoepidermal junction in the lamellar tissue of sheep. Quantitative real-time PCR results showed that compared with the control group, the mRNA expression of membrane-type metalloproteinase-1 ( = 0.049) was downregulated whereas the expression of proinflammatory IL-6 ( = 0.004) and matrix metalloprotease-9 ( = 0.037) was upregulated in the lamellar tissues of the oligofructose treatment group. In general, the present study provides the foundation for a sheep model of oligofructose-overload-induced acute laminitis that could be used in later experiments. Our findings suggest that intraruminal infusion of oligofructose altered ruminal microbiota and resulted in acute laminitis and that the inflammatory damage to the lamellae tissue may be related to the upregulation of matrix metalloprotease-9. The information generated will provide more insight into the systemic effects of lameness caused by oligofructose overload in sheep.

Abstract
OBJECTIVE The present study was designed to evaluate the effect of Adiponectin (APN) against alveolar epithelial apoptosis in chronic obstructive pulmonary disease (COPD) rat models. MATERIALS AND METHODS Thirty-six male Sprague-Dawley (SD) rats were randomly assigned to three groups: Sham group, COPD group, and COPD + APN group (2.5 ug/kg/day). To assess the effect of APN, histopathological evaluations, lung function, and the apoptotic index (AI) of alveolar septal cells, were performed. In addition, the levels of oxidative stress and endoplasmic reticulum stress were measured. RESULTS HE staining demonstrated that APN inhibited pathological injury in COPD rats. In addition, APN could restore the levels of superoxide dismutase (SOD) and malondialdehyde (MDA) in serum. APN also inhibited the levels of endoplasmic reticulum stress pathway including CHOP, phospho-JNK and Caspase-12 in alveolar epithelial cell. Furthermore, APN significantly inhibited the protein levels of Caspase-3 and apoptosis in alveolar epithelial cell of COPD rats. CONCLUSIONS Our findings suggested that APN might effectively ameliorate the progression of COPD via inhibiting the endoplasmic reticulum stress-induced alveolar epithelial apoptosis in rats.

Abstract
UNLABELLED In this study, label-free-based quantitative subcellular proteomics integrated with network analysis highlighted several candidate genes including P4HB, ITGB1, CD36, and ACTN1 that may be involved in osteoporosis. All of them are predicted as significant membrane proteins with high confidence and enriched in bone-related biological process. The results were further verified in transcriptomic and genomic levels. INTRODUCTION Osteoporosis is a metabolic bone disease mainly characterized by low bone mineral density (BMD). As the precursors of osteoclasts, peripheral blood monocytes (PBMs) are supported to be important candidates for identifying genes related to osteoporosis. We performed subcellular proteomics study to identify significant membrane proteins that involved in osteoporosis. METHODS To investigate the association between monocytes, membrane proteins, and osteoporosis, we performed label-free quantitative subcellular proteomics in 59 male subjects with discordant BMD levels, with 30 high vs. 29 low BMD subjects. Subsequently, we performed integrated gene enrichment analysis, functional annotation, and pathway and network analysis based on multiple bioinformatics tools. RESULTS A total of 1070 membrane proteins were identified and quantified. By comparing the proteins' expression level, we found 36 proteins that were differentially expressed between high and low BMD groups. Protein localization prediction supported the notion that the differentially expressed proteins, P4HB (p = 0.0021), CD36 (p = 0.0104), ACTN1 (p = 0.0381), and ITGB1 (p = 0.0385), are significant membrane proteins. Functional annotation and pathway and network analysis highlighted that P4HB, ITGB1, CD36, and ACTN1 are enriched in osteoporosis-related pathways and terms including "ECM-receptor interaction," "calcium ion binding," "leukocyte transendothelial migration," and "reduction of cytosolic calcium levels." Results from transcriptomic and genomic levels provided additional supporting evidences. CONCLUSION Our study strongly supports the significance of the genes P4HB, ITGB1, CD36, and ACTN1 to the etiology of osteoporosis risk.

Abstract
Human enterovirus 71 (EV71) is the major causative agent of hand, foot, and mouth disease (HFMD), particularly in infants and children below 4 years of age. Shikonin is a bioactive compound with anti-inflammatory, antiviral, and antibacterial activities derived from the roots of the Chinese medicinal herb Lithospermum erythrorhizon. This study aimed to examine the antiviral activity of PMM-034, a shikonin ester derivative, against EV71 in rhabdomyosarcoma (RD) cells. Cytotoxicity of PMM-034 on RD cells was determined using WST-1 assay. Dose- and time-dependent effects of PMM-034 on EV71 replication in RD cells were determined using plaque reduction assay. mRNA expression levels of EV71/VP1 and pro-inflammatory cytokines (IL-1β, IL-6, IL-8, and TNF-α) were determined by real-time RT-PCR, and EV71/VP1 and phospho-p65 protein expressions were determined by western blot analysis. PMM-034 exhibited only weak cytotoxicity against RD cells. However, PMM-034 exhibited significant antiviral activity against EV71 in RD cells with 50% inhibitory concentration of 2.31 μg/mL. The VP1 mRNA and protein levels were significantly reduced in cells treated with PMM-034. Furthermore, relative mRNA expression levels of IL-1β, IL-6, IL-8, and TNF-α significantly decreased in the cells treated with PMM-034, while the phospho-p65 protein expression was also significantly lower in the treated cells. These results indicated that PMM-034 suppressed the expressions of pro-inflammatory cytokines in RD cells, exhibiting antiviral activity against EV71, as evidenced by the reduced VP1 mRNA and protein levels in PMM-034-treated cells. Thus, PMM-034 is a promising candidate for further development as an EV71 inhibitor.

Abstract
The steady and oscillatory shear rate dependence of viscosity of a supercooled chalcogenide liquid of composition As10Se90 is measured at Newtonian viscosities ranging between 103 and 107 Pa s using capillary and parallel plate rheometry. The liquid displays strong violation of the Cox-Merz rule in the non-Newtonian regime where the viscosity under steady shear is nearly an order of magnitude lower than that under oscillatory shear. This behavior is argued to be related to the emergence of unusually large (6-8 nm) cooperatively rearranging regions with long relaxation times in the liquid that result from significant structural rearrangements under steady shear.

Abstract
BACKGROUND AND PURPOSE Prognosis in glioma depends strongly on tumor grade and proliferation. In this prospective study of patients with untreated primary cerebral gliomas, we investigated whether amide proton transfer-weighted imaging could reveal tumor proliferation and reliably distinguish low-grade from high-grade gliomas compared with Ki-67 expression and proton MR spectroscopy imaging. MATERIALS AND METHODS This study included 42 patients with low-grade (n = 28) or high-grade (n = 14) glioma, all of whom underwent conventional MR imaging, proton MR spectroscopy imaging, and amide proton transfer-weighted imaging on the same 3T scanner within 2 weeks before surgery. We assessed metabolites of choline and N-acetylaspartate from proton MR spectroscopy imaging and the asymmetric magnetization transfer ratio at 3.5 ppm from amide proton transfer-weighted imaging and compared them with histopathologic grade and immunohistochemical expression of the proliferation marker Ki-67 in the resected specimens. RESULTS The asymmetric magnetization transfer ratio at 3.5 ppm values measured by different readers showed good concordance and were significantly higher in high-grade gliomas than in low-grade gliomas (3.61% ± 0.155 versus 2.64% ± 0.185, P = .0016), with sensitivity and specificity values of 92.9% and 71.4%, respectively, at a cutoff value of 2.93%. The asymmetric magnetization transfer ratio at 3.5 ppm values correlated with tumor grade (r = 0.506, P = .0006) and Ki-67 labeling index (r = 0.502, P = .002). For all patients, the asymmetric magnetization transfer ratio at 3.5 ppm correlated positively with choline (r = 0.43, P = .009) and choline/N-acetylaspartate ratio (r = 0.42, P = .01) and negatively with N-acetylaspartate (r = -0.455, P = .005). These correlations held for patients with low-grade gliomas versus those with high-grade gliomas, but the correlation coefficients were higher in high-grade gliomas (choline: r = 0.547, P = .053; N-acetylaspartate: r = -0.644, P = .017; choline/N-acetylaspartate: r = 0.583, P = .036). CONCLUSIONS The asymmetric magnetization transfer ratio at 3.5 ppm may serve as a potential biomarker not only for assessing proliferation, but also for predicting histopathologic grades in gliomas.

Abstract
To characterize changes in ruminal epithelial bacterial communities and immune-related gene expression during concentrate starter feeding before weaning in lambs, 6 pairs of 10-d-old Hu lamb twins were selected: 1 kid received milk (M, = 6), and the other received milk plus starter (M+S, = 6). All lambs received hay and water ad libitum and were slaughtered at 56-d-old. Their rumen fluid was collected to determine ruminal pH and VFA levels; rumen epithelia were collected to characterize their bacterial communities using Illumina MiSeq sequencing and to determine mRNA expression of immune-related genes using quantitative real-time PCR (qRT-PCR). Results showed that starter feeding caused a decreased ruminal pH ( = 0.004) and increased concentrations of acetate, propionate, butyrate, and total VFA ( < 0.001). Principal coordinate analysis and analysis of molecular variance revealed that starter feeding affected ruminal epithelial bacterial communities in the lambs ( = 0.001), with higher relative abundance of dominant taxa , unclassified BS11 gut group, , unclassified Synergistaceae, , , , , and ( < 0.05) but lesser relative abundance of , unclassified Bacteroidales, unclassified Candidate, unclassified RF9, and ( < 0.05). Additionally, a phylogenetic investigation of communities by reconstruction of unobserved states analysis indicated that starter feeding markedly increased relative abundance values of dominant ruminal epithelial bacterial-inferred genes related to other ion-coupled transporters, pentose and glucuronate interconversions, glycosyltransferases, other glycan degradation, AA metabolism, sphingolipid metabolism, biotin metabolism, glycosphingolipid biosynthesis-globo series, and lysosome ( < 0.05) but decreased relative abundance values of genes related to carbon fixation pathways in prokaryotes and energy metabolism ( < 0.05) in the lambs. The qRT-PCR results showed that starter feeding decreased the relative mRNA expression of IL-6 ( = 0.003), IL-10 ( = 0.013), and interferon γ ( = 0.003). Collectively, this study showed that starter feeding could alter ruminal epithelial bacterial communities and some key immune-related genes' expression in preweaned lambs. All these responses of ruminal epithelial bacteria and the immune system would be beneficial for starter-fed lambs to be weaned.

Abstract
We investigate manifestations of topological order in monoaxial helimagnet Cr_{1/3}NbS_{2} by performing transport measurements on ultrathin crystals. Upon sweeping the magnetic field perpendicularly to the helical axis, crystals thicker than one helix pitch (48 nm) but much thinner than the magnetic domain size (∼1 μm) are found to exhibit sharp and hysteretic resistance jumps. We show that these phenomena originate from transitions between topological sectors with a different number of magnetic solitons. This is confirmed by measurements on crystals thinner than 48 nm-in which the topological sector cannot change-that do not exhibit any jump or hysteresis. Our results show the ability to deterministically control the topological sector of finite-size Cr_{1/3}NbS_{2} and to detect intersector transitions by transport measurements.

Abstract
Non-alcoholic fatty liver disease is a common chronic liver disease closely associated with obesity, hyperlipidemia, and diabetes. It can gradually progress to liver cirrhosis or even hepatocellular carcinoma; however, there are still no specific therapeutic agents for this disease. Liraglutide is a human glucagon-like peptide-1 analogue and has a marked effect in the treatment of type 2 diabetes. At present, many studies indicate that liraglutide also has a certain therapeutic effect on non-alcoholic fatty liver disease during the treatment of type 2 diabetes, but its mechanism of action remains unknown. This article reviews the known mechanisms of action of liraglutide in the treatment of non-alcoholic fatty liver disease.

Abstract
OBJECTIVES Mesenchymal stem cells (MSCs) have been widely used for regenerative medicine. Traditionally, the procedures of MSC isolation are usually invasive and time-consuming. Urine is merely a body waste, and recent studies have suggested that urine represents an alternative source of stem cells. We, therefore, determined whether the possibility of isolating mesenchymal-like stem cells was practical from human urine. METHODS A total of 16 urine samples were collected from pediatric patients. Urine-derived cells were isolated, expanded, and identified for specific cell surface markers using flow cytometry. Cell morphology was observed by microscopy. Osteogenic and adipogenic differentiation potential were determinded by culturing cells in specific induction medium, and assessed by alkaline phosphatase and oil red O stainings, respectively. RESULTS Clones were established and passaged successfully from primary cultures of urine cells. Cultured urine-derived cells at passage 3 were fusiform and arranged with certain directionality. Urine-derived cells at passage 5 displayed expressions of cell surface markers (CD29, CD105, CD166, CD90, and CD13). There was no expression of the general hematopoietic cell markers (CD45, CD34, and HLA-DR). Under in vitro induction conditions, urine-derived cells at passage 5 were able to differentiate into osteoblasts, but not adipocytes. CONCLUSIONS Urine may be a noninvasive source for mesenchymal-like stem cells. These cells could potentially provide a new source of autologous stem cells for regenerative medicine and cell therapy.

Abstract
Objective: To explore the value of near-infrared technology guided by indolecyanine green(ICG) in planning resection line and real-time surgical navigation in small liver cancer. Methods: From March to September 2015, 11 patients with hepatic tumors received hepatectomy were treated in First Department of Hepatobiliary Surgery, Zhujiang Hospital, Southern Medical University.There were 5 male and 6 female patients with average age of (55±10)years (range 39-70 years). Among whom, there were 9 cases with hepatocellular carcinoma and 2 cases with colorectal cancer. A near-infrared light camera system was used to detect the liver surfaces before resection, and to plan resection line and surgical specimens. A student's t test was used to compare continuous parametric variables. Results: The ICG-fluorescent imaging and histological examination had been used in the 15 lesions of the 11 patients. Among the 15 lesions, 7 lesions were detected by visual inspections, palpation and ICG-fluorescent imaging, 6 lesions were identified only by ICG-fluorescent imaging, 2 lesions were detected only by ICG-fluorescent imaging after resection.Results of pathologic examination indicated that the total fluorescent type include 5 well differentiated hepatocellular carcinoma and 2 cirrhotic nodule; the partial fluorescent type include 3 moderately differentiated hepatocellular carcinomas and 1 well differentiated hepatocellular carcinomas; the rim fluorescent type included 2 liver metastatic carcinoma and 2 poorly differentiated hepatocellular carcinomas. The average diameter of the tumor size measured by CT was (1.7±0.2)cm, while the average diameter measured by ICG-fluorescent imaging was (1.7±0.3)cm(t=-0.188, P>0.05). Conclusion: Near-infrared technology guided by ICG has important value in planning resection line and real-time surgical navigation in small liver cancer.

Abstract
Neurilemmomas, or called schwannomas, are tumors originating from schwann cells of the nerve sheath.With integrate capsules,the slow growing tumors are presenting benign properties in quite a few clinical cases.Approximately 25%~40% of all schwannomas were reported in the soft tissues of the head and neck. However,as a rare region, schwannomas in oral cavity was only reported less than 1% of all head and neck locations. We contribute the case of a 17 years old girl,who was experiencing progressive odynophagia and dysarthria. The lingual root's Neurilemmoma, as the final diagnosis, was confirmed by preoperative laryngendoscopy and histopathological examination. The surgery was conducted by suspension laryngoscope. Completely excised lesion was histopathological identified,which showed strong and diffuse staining with S100.
