Abstract
Background:TNFα inhibitors (TNFi) is effective for rheumatoid arthritis (RA) patients refractory to conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs), but because of high cost, the discontinuation is common that often lead to disease relapse.Objectives:To investigate, among RA patients refractory to csDMARDs but achieved therapy target after treated with TNFi and methotrexate (MTX), if the combination therapy of csDMARDs is more effective in reducing disease relapse than MTX monotherapy, and more cost-effective than continuing the treatment with TNFi and MTX.Methods:In this multi-center, outcome assessment blinded, randomized, superiority clinical trial, RA patients who failed to csDMARDs treatment (DAS28(CRP)>3.2) received MTX plus TNFi for 12 weeks first (induction therapy). Then patients achieving low disease activity [LDA, DAS28(CRP)<3.2] were randomized into three groups in 1:1:1 ratio: (A) maintaining TNFi + MTX for 60 weeks; (B) adding hydroxychloroquine (HCQ) and sulfasalazine (SSZ) for 12 weeks and then removing TNFi but continuing HCQ and SSZ for 48 weeks; and (C) maintaining TNFi + MTX for 12 weeks and then removing TNFi but continuing MTX only for 48 weeks. The primary outcome is disease relapse [DAS28(CRP) increased by at least 0.6 and >3.2] in 60 weeks. Secondary outcomes include the incremental cost effectiveness ratio (incremental cost per reducing 1% relapse rate); adverse events and radiology progression.Results:117 patients were enrolled for induction therapy. 67 patients achieved LDA after 12 weeks of induction therapy and were randomized with 21, 24 and 22 patients into each group, respectively. Male [OR=0.046 (0.005-0.451), p=0.008] and less baseline tender joint count [OR=0.825 (0.710-0.958), p=0.012] were independent predictive factors for LDA achievement. The relapse rate in 60 weeks was comparable between group A and B [33.3% (7/21) vs. 37.5% (9/24), p>0.05], while both significantly lower than that of group C [77.3% (17/22), p<0.01, p<0.01, respectively]. The adverse events and modified Sharp score progression were both comparable among the three groups. The incremental cost effectiveness ratio of group A is higher than group B (1315.7 yuan vs 101.5 yuan).Conclusion:For RA patients refractory to csDMARDs but achieved therapy target after treated with TNFi and MTX, the triple therapy of MTX+HCQ+SSZ is as effective as and more cost-effective than TNFi maintain therapy in reducing disease relapse. Both strategies are more effective than MTX monotherapy.References:[1]Smolen JS, Landewé R, Bijlsma J, et al.

Abstract
Objective: To evaluate the clinical effects of anterolateral thigh free flap with fascia lata in the repair of dura mater defect after resection of head squamous cell carcinoma. Methods: From June 2016 to June 2018, Xijing Hospital of Air Force Medical University applied the free transplantation of anterolateral thigh flap with fascia lata to repair the dura mater defect of 12 patients with head squamous cell carcinoma, including 9 males and 3 females, aged from 35 to 74 years. The size of scalp soft tissue defects in patients after carcinoma resection ranged from 12 cm×10 cm to 24 cm×21 cm, and the size of dura mater defect of patients ranged from 7 cm×6 cm to 16 cm×14 cm. The size of flap of patients ranged from 14 cm×12 cm to 27 cm×24 cm, and the size of fascia lata ranged from 8 cm×7 cm to 17 cm×15 cm. The superficial temporal artery and middle temporal vein were connected by end to end anastomosis with the first musculocutaneous perforating branch of the descending branch of lateral femoral artery and its accompanying vein. The flap donor area was transplanted with autologous split-thickness skin graft from trunk and fixed with packing. Postoperative survival of flaps and skin grafts was observed. The patients were followed up regularly. The cranial magnetic resonance imaging was performed to observe the recurrence of intracranial tumors and dural integrity, shape of the flap and whether the donor site region was left with significant dysfunction were observed. Results: All the flaps and skin grafts survived well in 12 patients after surgery. Ten patients had primary healing at the edge of the flap suture; 2 patients had local sinus tract formation at the suture site of flap, with a small amount of cerebrospinal fluid leakage, and were recovered after outpatient dressing change. The patients were followed up for 10 to 36 months, and 3 patients with tumors involving in the dura mater sagittal sinus region had postoperative intracranial tumor recurrence. The tumor was resected again. All the patients had good dural integrity. The flaps of all patients were in good shape, and no obvious dysfunction remained in the flap donor site. Conclusions: Free transplantation of anterolateral thigh flap with fascia lata is an effective and reliable method to repair the dura mater defect following head squamous cell carcinoma resection. It can repair the scalp and dura mater defects caused by the invasion of squamous cell carcinoma and provide possibilities for skull reconstruction.

Abstract
Objective: To investigate the effect of Silent information regulator 1 (Sirt1) on the expression profile of long non-coding RNA (lncRNA) in macrophages upon lipopolysaccharide (LPS) treatment. Methods: Peritoneal macrophages (PM) were isolated from nine wild-type C57BL/6 male mice (wild-type group) and nine myeloid-specific Sirt1 knock-out mice (knock-out group). RNA samples were extracted from macrophages stimulated with 1 μg/ml LPS. Sequencing and the differentially expressed lncRNA were screened after the RNA was quantified. The threshold set for up-and down-regulated genes was a fold change (wild-type group/knock-out group) ≥2 and P≤0.05. Afterwards, gene ontology (GO) and pathway enrichment analysis were conducted and co-expression network map was constructed. Results: Four hundred and forty five lncRNA genes were differentially expressed (185 lncRNA genes were up-regulated and 260 lncRNA genes were down-regulated). Two hundred mRNA genes were differentially expressed (113 mRNA genes were up-regulated and 87 mRNA genes were down-regulated). It was found that the differentially expressed lncRNA genes and the predicted corresponding target genes were mainly distributed in the regions of biological processes of macrophage inflammatory response, macrophage chemotaxis and cell metabolism by GO and pathway enrichment analysis. Conclusion: lncRNA expression profile changes significantly in LPS induced macrophages isolated from Sirt1 knock out mice, which is closely related to the function of macrophages.

Abstract
AIMS The objective of this study was to determine the effects of sophorolipids on several fungal and oomycete plant pathogens and the relationship between sophorolipids at different pH and antimicrobial activities. METHODS AND RESULTS Sophorolipids had different solubility at different pH with a dramatic increase in solubility when pH was 6 or higher. Inhibition of mycelial growth of Phytophthora infestans by sophorolipids was affected by pH values, showing that when the pH value was higher, the inhibition rate was lower. Sophorolipids inhibited spore germination and mycelial growth of several fungal and oomycete pathogens in vitro including Fusarium sp., F. oxysporum, F. concentricum, Pythium ultimum, Pyricularia oryzae, Rhizoctorzia solani, Alternaria kikuchiana, Gaeumannomyces graminis var. tritici and P. infestans and caused morphological changes in hyphae by microscope observation. Sophorolipids reduced β-1,3-glucanase activity in mycelia of P. infestans. In greenhouse studies, foliar application of sophorolipids at 3 mg ml-1 reduced severity of late blight of potato caused by P. infestans significantly. CONCLUSION Sophorolipids influenced spore germination and hyphal tip growth of several plant pathogens and pH solubility of sophorolipids had an effect on their efficacy. Application of sophorolipids reduced late blight disease on potato under greenhouse conditions. SIGNIFICANCE AND IMPACT OF THE STUDY The findings indicated that sophorolipids have the potential to be developed as a convenient and easy-to-use formulation for managing plant diseases.

Abstract
AIM The aims of this study were to identify races and mating types of Setosphaeria turcica causing northern corn leaf blight in Heilongjiang province of China and analyse the genetic diversity of S. turcica isolates using SSR markers. METHODS AND RESULTS Based on gene-for-gene interactions, 13 races of S. turcica (races 0, 1, 2, 3, 12, 13, 23, 123, N, 1N, 12N, 3N and 23N) were isolated from infected corn plants in Heilongjiang province. Races 0 and 1 were the predominant races, and race 23N was identified for the first time in the region. Using two pairs of specific primers, three mating types, 'a', 'Aa' and 'A', were identified, with 'a' being the predominant mating type. SSR markers were used to analyse genetic diversity of 60 S. turcica isolates. Five SSR primers were polymorphic, which resulted in 45 reproducible bands with 2-15 bands for each primer. Cluster analysis separated the isolates into five groups at a similarity coefficient of 0·84. Analysis of molecular variance showed that there was significant correlation between SSR groups and mating type of the isolates. No significant correlation was found between SSR groups and physiological races or geographical location of the isolates. CONCLUSIONS The work reported that races 0 and 1 were the predominant races, and race 23N was identified for the first time in Heilongjiang province with 'a' being the predominant mating type. There was significant correlation between SSR groups and mating type of S. turcica isolates. SIGNIFICANCE AND IMPACT OF THE STUDY Our results provide information on population structure and genetic diversity of S. turcica causing Northern corn leaf blight, which will facilitate the development of effective disease management programs.

Abstract
Programmed cell death protein 1 (PD-1), as a checkpoint of the immune signaling pathway, is a hotspot in the field of immuno-oncology. Its binding with ligand (PD-L1) is an important negative regulatory mechanism. Application of PD-1/PD-L1 inhibitors in treatments of breast cancer is still being explored at present. Fully understanding the mechanism of PD-1/PD-L1 in the microenvironment of breast cancer will help their inhibitors play a full role. This review will start with the discovery of PD-1 and PD-L1, describe their main signaling pathways, introduce the common types and applications of PD-1/PD-L1 inhibitors, especially in breast cancer, summarize the basic research of PD-1 and PD-L1 in breast cancer microenvironment in recent years, and seek new strategies of PD-1/PD-L1 inhibitors in breast cancer treatment.

Abstract
Investigating two-dimensional (2D) self-assembled structures of biological monomers governed by intermolecular interactions is a prerequisite to understand the self-assembly of more complex biomolecular systems. 5,6-Dihydroxyindole carboxylic acid (DHICA) is one of the building blocks of eumelanin - an irregular heteropolymer and the most common form of melanin which has potential applications in organic electronics and bioelectronics. By means of scanning tunneling microscopy, density functional theory and Monte Carlo calculations, we investigate DHICA molecular configurations and interactions underlying the multiple 2D patterns formed on Au(111). While DHICA self-assembled molecular networks (SAMNs) are dominated by the hydrogen bonding of carboxylic acid dimers, a variety of 2D architectures are formed due to the multiple weak interactions of the catechol group. The hydroxyl group also allows for redox reactions, caused by oxidation via O2 exposure, resulting in molecular rearrangement. The susceptibility of the molecules to oxidation is affected by their SAMNs architectures, giving insights on the reactivity of indoles as well as highlighting non-covalent assembly as an approach to guide selective oxidation reactions.

Abstract
Abstract
Background: Breast cancer is a severe public health problem for women worldwide. Race disparities and regional disparities are documented regarding incidence, mortality, and survival of breast cancer patients. However, the associations between socioeconomic status and survival outcomes of breast cancer remain unclear and require a comprehensive large-scale investigation of specific socioeconomic factors. Furthermore, no model has included both histological and socioeconomic factors together to predict survival of breast cancer. In this study, we sought to develop nomograms to predict overall survival (OS) and breast cancer-specific survival (BCSS) with consideration of socioeconomic factors for non-metastasis breast cancer.
Methods: We included a total of 274,108 female patients, diagnosed with malignant breast cancer between 2007 and 2014from the Surveillance, Epidemiology, and End Results (SEER) database. Socioeconomic factors involving marital status, insurance status, residence, median household income, poverty rate, unemployment rate and education level were included in the analysis. OS and BCSS were evaluated with log-rank tests and Kaplan-Meier estimates. We identified and integrated significant prognostic factors for OS and BCSS using univariate and multivariate Cox regression analysis to construct nomograms. Calibration plots and concordance indexes were used to evaluate the accuracy and discrimination of the models.
Results: Among different age subgroups, insured patients were more likely to have better survival than uninsured patients or patients with Medicaid (P<0.001), and especially for patients who were aged 18 to 35 years old at diagnosis, uninsured patients associated with poor BCSS than Medicaid patients (P<0.05). Through multivariate analysis, we found non-Hispanic black patients experienced worst survival compared with the White and other races (P<0.001). Interestingly, married (vs. single vs. separated/divorced/widowed; P<0.001) and insured (vs. Medicaid vs. uninsured; P<0.001) patients had a better prognosis. Living in the non-metro area increased the risk of death (hazard ratio [HR], 1.084, P<0.05). Furthermore, living in counties with higher median household income (>US $72,800) had favorable impacts on OS (HR 0.843, P<0.001). Four and five socioeconomic factors were involved in constructing the nomograms for 3 years-, 5 years- and 7 years- OS and BCSS, respectively. The C-indexes of the final nomograms were higher than those of the TNM staging system for predicting OS (0.776 vs 0.678; P < 0.001) and BCSS (0.842 vs 0.776; P < 0.001), respectively. The performance of the nomograms for predicting OS was significantly lower when excluding the socioeconomic factors (P < 0.001).
Conclusion: Some certain socioeconomic factors (i.e., marital status, insurance status, median household income, and residence) play essential roles in predicting survival of non-metastasis breast cancer. We constructed and validated nomograms including socioeconomic factors to provide more comprehensive and realistic survival estimation. Besides, these findings may highlight the importance of developing health-related policies and the necessity of targeted social support-based interventions for those high-risk patients.

Abstract
Abstract
Background: Metastatic regional lymph nodes (LN) is a strong predictor of worse long-term outcome after resection of breast cancer. This study aimed to compare the prognostic performance of American Joint Committee on Cancer (AJCC) N stage relative to lymph node ratio (LNR), log odds of metastatic lymph nodes (LODDS), number of removed lymph nodes (NRLNs), and number of negative lymph nodes (NNLNs) in breast cancer patients.
Methods: All of the breast cancer patients who underwent surgery between 2004 and 2012 were identified from the Surveillance, Epidemiology, and End Results database. Restricted cubic spline functions were used to characterize the association between continuous variables and the risk of death and determine the optimal cut-off points. The Cox proportional hazards models were constructed, and the relative discriminative abilities of the different LN staging systems were assessed using the Akaike's Information Criterion (AIC) and the Harrell's concordance index (C-index).
Results: A total of 264,096 breast cancer patients were enrolled, and 177,598 (67.2%) had no lymph node metastasis, whereas 86,498 (32.8%) had lymph node metastasis. 187,785 (71.1%) patients had a limited number of LNs harvested (NRLN <10). The median follow-up time was 73 months, and the 8-year overall survival (OS) and breast cancer-specific survival (BCSS) were 82.6% and 90.4%, respectively. LNR, LODDS, NRLNs, and NNLNs were all nonlinearly associated with OS and BCSS. Patients with metastatic LN had an increased risk of OS (hazards ratio: 2.32, 95% confidence interval: 2.27–2.37; P < 0.001) and BCSS (hazards ratio: 4.53, 95% confidence interval: 4.40–4.66; P < 0.001). When LNR was equal to 0 or 1, there was a heterogeneity of outcomes, and LODDS still yielded informative values compared to LNR. Among the entire cohort, LNR modeled as a continuous variable had a somewhat better prognostic performance (AIC: 923231.4 and C-index: 0.722 for OS; AIC: 482962.3 and C-index: 0.817 for BCSS) than any of other LN staging systems. However, a model with AJCC N stage showed the best fit in patients with a limited number of LNs harvested (AIC: 501321.8 and C-index: 0.699 for OS; AIC: 212605.6 and C-index: 0.809 for BCSS). When assessed among patients with metastatic LN, LODDS outperformed other staging systems including AJCC N stage, LNR, NRLNs and NNLNs, whenever assessed using continuous (AIC: 428626.2 and C index: 0.728 for OS; AIC: 296886.8 and C index: 0.770 for BCSS) or categorical (AIC: 429527.5 and C index: 0.722 for OS; AIC: 297796.6 and C index: 0.762 for BCSS) cutoff values.
Conclusions: Although LNR assessed as a continuous variable was the most potent method to stratify patients regardless of LN status, the prognostic superiority of LNR is confounded by a limited LN harvest. LODDS was a better and more powerful predictor of survival when patients were LN positive, especially among those patients with either very low or high LNR.

Abstract
OBJECTIVES To perform a systematic review and meta-analysis on the effects of audiovisual distraction on reducing dental anxiety in children during dental treatment under local anesthesia. METHODS The authors identified eligible reports published through August 2017 by searching PubMed, EMBASE, and Cochrane Central Register of Controlled Trials. Clinical trials that reported the effects of audiovisual distraction on children's physiological measures, self-reports, and behavior rating scales during dental treatment met the minimum inclusion requirements. The authors extracted data and performed a meta-analysis of appropriate articles. RESULTS Nine eligible trials were included and qualitatively analyzed; some of these trials were also quantitatively analyzed. Among the physiological measures, heart rate or pulse rate was significantly lower (p = .01) in children subjected to audiovisual distraction during dental treatment under local anesthesia than in those who were not; a significant difference in oxygen saturation was not observed. The majority of the studies using self-reports and behavior rating scales suggested that audiovisual distraction was beneficial in reducing anxiety perception and improving children's cooperation during dental treatment. CONCLUSION The audiovisual distraction approach effectively reduces dental anxiety among children. Therefore, we suggest the use of audiovisual distraction when children need dental treatment under local anesthesia.

Abstract
To validate the Pain Resilience Scale (PRS) for use in Chinese patients with temporomandibular disorders (TMD) pain. According to international guidelines, the original PRS was first translated and cross-culturally adapted to formulate the Chinese version of PRS (PRS-C). A total of 152 patients with TMD pain were recruited to complete series of questionnaires. Reliability of the PRS-C was investigated using internal consistency and test-retest reliability. Validity of the PRS-C was calculated using cross-cultural validity and convergent validity. Cross-cultural validity was evaluated by examining the confirmatory factor analysis (CFA). And convergent validity was examined through correlating the PRS-C scores with scores of 2 commonly used pain-related measures (the Connor-Davidson Resilience Scale [CD-RISC] and the Tampa Scale for Kinesiophobia for Temporomandibular Disorders [TSK-TMD]). The PRS-C had a high internal consistency (Cronbach's alpha = 0.92) and good test-retest reliability (intra-class correlation coefficient [ICC] = 0.81). The CFA supported a 2-factor model for the PRS-C with acceptable fit to the data. The fit indices were chi-square/DF = 2.21, GFI = 0.91, TLI = 0.97, CFI = 0.98 and RMSEA = 0.08. As regards convergent validity, the PRS-C evidenced moderate-to-good relationships with the CD-RISC and the TSK-TMD. The PRS-C shows good psychometric properties and could be considered as a reliable and valid measure to evaluate pain-related resilience in patients with TMD pain.

Abstract
OBJECTIVES To summarize the characteristics of family homicide cases and to provide reference for the analysis and prevention of such cases. METHODS Seventeen solved family homicide cases in Liyang from 2004 to 2014 were investigated. The original registration information, record of scene investigation, corpse inspection report and case situation were analyzed statistically. RESULTS The characteristics of the 17 family homicides cases showed that most victims were female and most suspects were male, and spouse infidelity and suspected spouse infidelity have higher proportion in the motives for the killings. Murders by patients with psychosis, camouflage murders and murder-suicides occupied a certain proportion in the family homicide cases. CONCLUSIONS The family homicide cases are correlated with the family factors such as extramarital sexual intercourse and murder by patients with psychosis. Some suspects suicided after murder. The tools for committing crimes have the features of simplicity, randomness and easy source availability.

Moisá SJ, Ji P, Drackley JK, Rodriguez-Zas SL, Loor JJ. Transcriptional changes in mesenteric and subcutaneous adipose tissue from Holstein cows in response to plane of dietary energy. J Anim Sci Biotechnol 2017; 8:85. [PMID: 29214018 PMCID: PMC5713657 DOI: 10.1186/s40104-017-0215-z] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2017] [Accepted: 10/18/2017] [Indexed: 12/15/2022] Open
Abstract
Background Dairy cows can readily overconsume dietary energy during most of the prepartum period, often leading to higher prepartal concentrations of insulin and glucose and excessive body fat deposition. The end result of these physiologic changes is greater adipose tissue lipolysis post-partum coupled with excessive hepatic lipid accumulation and compromised health. Although transcriptional regulation of the adipose response to energy availability is well established in non-ruminants, such regulation in cow adipose tissue depots remains poorly characterized. Results Effects of ad-libitum access to high [HIGH; 1.62 Mcal/kg of dry matter (DM)] or adequate (CON; 1.35 Mcal/kg of DM) dietary energy for 8 wk on mesenteric (MAT) and subcutaneous (SAT) adipose tissue transcript profiles were assessed in non-pregnant non-lactating Holstein dairy cows using a 13,000-sequence annotated bovine oligonucleotide microarray. Statistical analysis revealed 409 and 310 differentially expressed genes (DEG) due to tissue and diet. Bioinformatics analysis was conducted using the Dynamic Impact Approach (DIA) with the KEGG pathway database. Compared with SAT, MAT had more active biological processes related to adipose tissue accumulation (adiponectin secretion) and signs of pro-inflammatory processes due to adipose tissue expansion and macrophage infiltration (generation of ceramides). Feeding the HIGH diet led to changes in mRNA expression of genes associated with cell hypertrophy (regucalcin), activation of adipogenesis (phospholipid phosphatase 1), insulin signaling activation (neuraminidase 1) and angiogenesis (semaphorin 4G, plexin B1). Further, inflammation due to HIGH was underscored by mRNA expression changes associated with oxidative stress response (coenzyme Q3, methyltransferase), ceramide synthesis (N-acylsphingosine amidohydrolase 1), and insulin signaling (interferon regulatory factor 1, phosphoinositide-3-kinase regulatory subunit 1, retinoic acid receptor alpha). Activation of ribosome in cows fed HIGH indicated the existence of greater adipocyte growth rate (M-phase phosphoprotein 10, NMD3 ribosome export adaptor). Conclusions The data indicate that long-term ad-libitum access to a higher-energy diet led to transcriptional changes in adipose tissue that stimulated hypertrophy and the activity of pathways associated with a slight but chronic inflammatory response. Further studies would be helpful in determining the extent to which mRNA results also occur at the protein level.

Abstract
Anemia is characteristic of myelodysplastic syndromes (MDS). The mechanisms of anemia in MDS are unclear. Using a mouse genetic approach, here we show that dual deficiency of mDia1 and miR-146a, encoded on chromosome 5q and commonly deleted in MDS (del(5q) MDS), causes an age-related anemia and ineffective erythropoiesis mimicking human MDS. We demonstrate that the ageing bone marrow microenvironment is important for the development of ineffective erythropoiesis in these mice. Damage-associated molecular pattern molecules (DAMPs), whose levels increase in ageing bone marrow, induced TNFα and IL-6 upregulation in myeloid-derived suppressor cells (MDSCs) in mDia1/miR-146a double knockout mice. Mechanistically, we reveal that pathologic levels of TNFα and IL-6 inhibit erythroid colony formation and differentially affect terminal erythropoiesis through reactive oxygen species-induced caspase-3 activation and apoptosis. Treatment of the mDia1/miR-146a double knockout mice with all-trans retinoic acid, which promoted the differentiation of MDSCs and ameliorated the inflammatory bone marrow microenvironment, significantly rescued anemia and ineffective erythropoiesis. Our study underscores the dual roles of the ageing microenvironment and genetic abnormalities in the pathogenesis of ineffective erythropoiesis in del(5q) MDS.
