Abstract
BACKGROUND Preclinical evidence suggests that general anesthetics can dose dependently induce neurodegeneration in the developing brains of animals which can be reliably determined by measurement of blood S100β, but this correlation remains unclear in humans. We hypothesized that S100β would not be increased in cord arterial blood of fetuses exposed briefly to general anesthetics during a C-section, compared with epidural anesthesia. METHODS A prospective observational clinical study comparatively measured changes of brain damage biomarker S100β ratio of umbilical artery over vein (changes after fetus circulation) immediately after delivery under C-section with either epidural or general anesthesia. Newborn blood gas measurements, APGAR scores, and maternal well-being were also compared. RESULTS Compared with epidural anesthesia, general anesthesia resulted in the lower S100β ratio of umbilical artery over the vein (medium 2.64 [quartiles 1.39, 3.45] vs. medium 1.59 [quartiles 0.88, 2.01], P = 0.031), without changing the S100β level in the vein of the mother. There was no significant difference between general and epidural anesthesia when comparing other maternal and newborn parameters. CONCLUSION S100β levels in newborn after C-section is lower with general anesthesia than epidural anesthesia, with unclear mechanisms.

Abstract
Previous studies have shown that GLABRA3 (AtGL3), a bHLH transcription factor, plays essential roles in anthocyanin biosynthesis and trichome formation in Arabidopsis thaliana. However, there have been no such studies of a homologue, BnGL3, from the closely related crop, Brassica napus. Here, we analysed the BnGL3-1 coding domain sequence from the B. napus cultivar QINYOU Seven, identified conserved protein domains and performed a phylogenetic analysis to elucidate its relationship with homologues form a range of plant species. When expressed in tobacco leaves as a fusion protein with green fluorescent protein, BnGL3-1 accumulated in the nucleus, consistent with its predicted function as a transcription factor. Ectopic expression of the BnGL3-1 gene in the A. thaliana gl3-3 mutant resulted in levels of anthocyanins and numbers of trichomes in true leaves that were higher than in wild-type plants. Moreover, overexpression of BnGL3-1 in gl3-3 compensated for the promotion and repression of genes involved in anthocyanin biosynthesis and trichome formation, respectively, that has been reported in gl3-3 young shoots and expanding true leaves. This study provides new insights into GL3 function in anthocyanin biosynthesis and trichome formation in crucifers, and represents a promising target for genetic manipulation of B. napus.

Abstract
Objective: To determine the age-related coronary risk factors in Chinese patients with acute myocardial infarction (AMI). Methods: Among 31 provinces, municipalities or autonomous districts in China, from January 1st 2013 to September 30th 2014, 24 394 consecutive AMI patients who were admitted to 107 hospitals were divided into five groups according to age. Cardiovascular risk factors of groupⅠ (<45 years, n=2 307), group Ⅱ (45-54 years, n=4 448), group Ⅲ (55-64 years, n=7 029), group Ⅳ (65-74 years, n=6 147) and group Ⅴ (≥75 years, n=4 463) patients were compared. Results: Among 24 394 AMI patients [with a mean age of (62.2±13.8) years, 18 162 males], 24.7% patients had three and more conventional modifiable cardiovascular risk factors. ST-elevation myocardial infarction (STEMI) was diagnosed in 18 209 (74.6%) patients. The ratios of female, hypertension and diabetes tended to increase with the increase of age. Young AMI patients were predisposed to smoking, overweight/obesity and hyperglycemia. Nearly 90% patients in group Ⅰ and group Ⅱ were male. The ratio of male patients (92.3% to 58.0%), overweight/obesity (63.9% to 37.4%), current smoking (68.7% to 19.8%), dyslipidemia (9.1% to 4.5%), family history of premature coronary artery disease (CAD) (6.2% to 1.2%) and eating greasy food (86.1% to 66.2%) decreased markedly from group Ⅰ to Ⅴ patients. Proportion of hypertension gradually increased from 34.3% in group Ⅰ patients to 57.9% in group Ⅴ patients. Diabetes was most common to group Ⅳ (65-74 years) patients. Conclusion: There were different risk factors for AMI patients in different age groups, and young AMI patients were predisposed to live an unhealthy lifestyle.

Abstract
Melatonin, synthesized primarily by the pineal gland, is a neuroendocrine hormone with high membrane permeability. The vascular effects of melatonin, including vasoconstriction and vasodilation, have been demonstrated in numerous studies. However, the mechanisms underlying these effects are not fully understood. Large-conductance Ca2+-activated K+ (BKCa) channels are expressed broadly on smooth muscle cells and play an important role in vascular tone regulation. This study explored the mechanisms of myocyte BKCa channels and endothelial factors underlying the action of melatonin on the mesenteric arteries (MAs). Vascular contractility and patch-clamp studies were performed on myocytes of MAs from Wistar rats. Melatonin induced significant vasodilation on MAs. In the presence of Nω-nitro-l-arginine methyl ester (l-NAME), a potent endothelial oxide synthase (eNOS) inhibitor, melatonin elicited concentration-dependent relaxation, with lowered pIC50 The effect of melatonin was significantly attenuated in the presence of BKCa channel blocker iberiotoxin or MT1/MT2 receptor antagonist luzindole in both (+) l-NAME and (-) l-NAME groups. In the (+) l-NAME group, iberiotoxin caused a parallel rightward shift of the melatonin concentration-relaxation curve, with pIC50 lower than that of luzindole. Both inside-out and cell-attached patch-clamp recordings showed that melatonin significantly increased the open probability, mean open time and voltage sensitivity of BKCa channels. In a cell-attached patch-clamp configuration, the melatonin-induced enhancement of BKCa channel activity was significantly suppressed by luzindole. These findings indicate that in addition to the activation of eNOS, melatonin-induced vasorelaxation of MAs is partially attributable to its direct (passing through the cell membrane) and indirect (via MT1/MT2 receptors) activation of the BKCa channels on mesenteric arterial myocytes.

Abstract
The molecular mechanisms underlying the opposing functions of glucocorticoid receptors (GRs) and estrogen receptor α (ERα) in breast cancer development remain poorly understood. Here we report that, in breast cancer cells, liganded GR represses a large ERα-activated transcriptional program by binding, in trans, to ERα-occupied enhancers. This abolishes effective activation of these enhancers and their cognate target genes, and it leads to the inhibition of ERα-dependent binding of components of the MegaTrans complex. Consistent with the effects of SUMOylation on other classes of nuclear receptors, dexamethasone (Dex)-induced trans-repression of the estrogen E2 program appears to depend on GR SUMOylation, which leads to stable trans-recruitment of the GR-N-CoR/SMRT-HDAC3 corepressor complex on these enhancers. Together, these results uncover a mechanism by which competitive recruitment of DNA-binding nuclear receptors/transcription factors in trans to hot spot enhancers serves as an effective biological strategy for trans-repression, with clear implications for breast cancer and other diseases.

Abstract
OBJECTIVE Understanding the cartilage surface structure, lost in arthritic disease, is essential for developing strategies to effectively restore it. Given that adherence of the lubricating protein, lubricin, to the cartilage surface is critical for boundary lubrication, an interaction with cartilage oligomeric matrix protein (COMP) was investigated. COMP, an abundant cartilage protein, is known to be important for matrix formation. DESIGN Synovial fluid (SF) from arthritic patients was used to detect possible COMP-lubricin complexes by immunological methods. Recombinant (RC) COMP and lubricin fragments were expressed to characterize this bonding and mass spectrometry employed to specifically identify the cysteines involved in inter-protein disulfide bonds. RESULTS COMP-lubricin complexes were identified in the SF of arthritic patients by Western blot, co-immunoprecipitation and sandwich ELISA. RC fragment solid-phase binding assays showed that the C-terminal (amino acids (AA) 518-757) of COMP bound non-covalently to the N-terminal of lubricin (AA 105-202). Mass spectrometry determined that although cysteines throughout COMP were involved in binding with lubricin, the cysteines in lubricin were primarily focused to an N-terminal region (AA 64-86). The close proximity of the non-covalent and disulfide binding domains on lubricin suggest a two-step mechanism to strongly bind lubricin to COMP. CONCLUSION These data demonstrate that lubricin forms a complex network with COMP involving both non-covalent and covalent bonds. This complex between lubricin and the cartilage protein COMP can be identified in the SF of patients with arthritis conditions including osteoarthritis (OA) and rheumatoid arthritis (RA).

Abstract
Water vapor noise in the air affects the accuracy of optical parameters extracted from terahertz (THz) time-domain spectroscopy. In this paper, a numerical method was proposed to eliminate water vapor noise from the THz spectra. According to the Van Vleck-Weisskopf function and the linear absorption spectrum of water molecules in the HITRAN database, we simulated the water vapor absorption spectrum and real refractive index spectrum with a particular line width. The continuum effect of water vapor molecules was also considered. Theoretical transfer function of a different humidity was constructed through the theoretical calculation of the water vapor absorption coefficient and the real refractive index. The THz signal of the Lacidipine sample containing water vapor background noise in the continuous frequency domain of 0.5-1.8 THz was denoised by use of the method. The results show that the optical parameters extracted from the denoised signal are closer to the optical parameters in the dry nitrogen environment.

Abstract
PurposeTo investigate the retinal structural changes in endophthalmitis and their association with visual outcome.Patients and methodsForty-five eyes of 45 patients diagnosed with endophthalmitis were included. Spectral domain optical coherence tomography (SD-OCT) was performed after inflammation was controlled. The relationship between SD-OCT features and best-corrected visual acuity (BCVA) at the last follow-up was analyzed.ResultsThe structural changes included inner segment ellipsoid (ISe) disruption (49%), atrophy of retinal inner layers (24%), epimacular membrane (24%), and macular edema (24%). BCVA was worse in patients with ISe disruption (P=0.005) and retinal inner layers' atrophy (P=0.004) compared with those without. There was no significant difference of BCVA between the patients with and without epimacular membrane, or intraretinal cysts. Multivariate regression showed that atrophy of retinal inner layers (b=0.41±0.17, P=0.022) was the only independent factor associated with BCVA.ConclusionAtrophy of retinal inner layers is associated with visual impairment in endophthalmitis, despite successful management.

Abstract
Research indicates that after EGFR-tyrosine kinase inhibitors (EGFR-TKIs) treatment of non-small cell lung cancer (NSCLC), patient immune function significantly improved, and that circulating tumor cells (CTCs) measurements and peripheral blood epidermal growth factor receptor (EGFR) mutation data can guide TKIs treatment. Sixty-six advanced NSCLC patients treated with TKIs were enrolled and CTCs, EGFR expression, T cell subsets and natural killer (NK) cells in peripheral blood were measured using flow cytometry before and after treatment and assessed with respect to patient prognosis. CTCs and EGFR expression were negatively correlated with cellular immune function and immune recovery after EGFR-TKI treatment. Thus, CD4+/ CD8+ ratios and NK cells may be useful prognostic indicators for advanced NSCLC patients who receive TKIs treatment.

Abstract
Immunotherapeutic approaches, particularly PD-1/PD-L1 blockade, have improved the treatment of non-small cell lung cancer (NSCLC), supporting the premise that evasion of immune destruction is of importance for NSCLC progression. However, the signals responsible for upregulation of PD-L1 in NSCLC cells and whether they are integrated with the regulation of other immune-related genes are not known. Mucin 1 (MUC1) is aberrantly overexpressed in NSCLC, activates the NF-κB p65→ZEB1 pathway and confers a poor prognosis. The present studies demonstrate that MUC1-C activates PD-L1 expression in NSCLC cells. We show that MUC1-C increases NF-κB p65 occupancy on the CD274/PD-L1 promoter and thereby drives CD274 transcription. Moreover, we demonstrate that MUC1-C-induced activation of NF-κB→ZEB1 signaling represses the TLR9, IFNG, MCP-1 and GM-CSF genes, and that this signature is associated with decreases in overall survival. In concert with these results, targeting MUC1-C in NSCLC tumors suppresses PD-L1 and induces these effectors of innate and adaptive immunity. These findings support a previously unrecognized central role for MUC1-C in integrating PD-L1 activation with suppression of immune effectors and poor clinical outcome.

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
OBJECTIVES MicroRNA-155 (miR-155) regulates T-cell differentiation and activation. It has also been associated with HIV infection. However, it remains unclear whether miR-155 is related to the T-cell response in HIV-infected individuals (e.g. T-cell activation and exhaustion). METHODS We performed a cross-sectional study involving 121 HIV-1-infected patients on highly active antiretroviral therapy (HAART) and 43 HAART-naïve patients. MiR-155 levels in the peripheral blood were determined by quantitative reverse transcription-polymerase chain reaction (PCR). T-cell immune activation, exhaustion, and homeostasis were measured by determining the expression of CD38, programmed death 1 (PD-1) and CD127 via flow cytometry. RESULTS The levels of miR-155 in total peripheral blood mononuclear cells, CD4 T cells and CD8 T cells from HIV-1-infected patients were increased (P < 0.01). Nonresponders and HAART-naïve patients also exhibited a higher percentage of CD8+ CD38+ T cells and a lower percentage of CD4+ CD127+ and CD8+ CD127+ T cells (P < 0.05). We also found higher levels of PD-1 expression on the CD4+ and CD8+ T cells of HIV-1-infected patients (P < 0.05). CONCLUSIONS Our findings suggest that miR-155 levels in the peripheral blood of HIV-1-infected patients are increased and associated with T-cell activation. Therefore, miR-155 is a potential biomarker of the immune response following HIV-1 infection.

Four Hyriopsis cumingii populations, a breeding population (BP), a cultured population (FP), two wild populations from Poyang Lake (PY) and Dongting Lake (DT), and an H. schlegelii population were collected (JX), and the first filial generations (F1) were bred synchronously. The shell nacre polymorphisms, population genetic diversity, and genetic structures of the F1 of each population were analyzed and compared using CIELAB colorimetric measurements and microsatellite markers. The color parameters of the shell nacre (L*, a*, dE*) in the BP were significantly different from those in the FP, PY, and JX populations (P < 0.05), whereas the shell nacre color did not differ significantly between the left and right sides of the shells within the same population (P > 0.05). The BP had relatively darker nacre at the posterior end of the shell, and the color parameters (L*, a*, b*, and dE*) differed significantly from those at the front end (P < 0.05). The five populations showed relatively high levels of genetic diversity (HO = 0.733-0.829). The genetic distance between the H. cumingii populations and H. schlegelii was the greatest, whereas that within the H. cumingii populations and between the FP and the PY population was the smallest. All the individuals tested in this study were optimally grouped into four theoretical populations. In conclusion, the BP was significantly different from the base populations of PY and DT in terms of genetic background and phenotypic parameters of shell nacre color, with potential for further genetic improvement.

Abstract
OBJECTIVE To investigate the association between different kinds of systolic blood pressure (SBP, including office, visit-to-visit, 24-hour ambulatory) and vascular damages (represented by carotid intima-media thickness, CIMT; brachial-ankle pulse wave velocity, baPWV) in the elderly. METHODS A total of 2 814 participants aged of ≥60 years old and retired employees were selected with random sampling method from the individuals who took part in 2006-2007, 2008-2009, 2010-2011 health examination in Tangshan Kailuan Hospital, Kailuan Linxi Hospital, Kailuan Zhaogezhuang Hospital and with 24-hour ambulatory blood pressure monitoring data, CIMT and baPWV.Finally, 2 146 participants (1 438 males, average age (67.3±6.0) years old) were included to the analysis.Multivariable regression analysis was used to analyze association between the office, visit-to-visit, 24-hour, day-time, night-time SBP and CIMT and baPWV, respectively. RESULTS (1) The average SBP, DBP, CIMT and baPWV were (137.0±20.4) mmHg(1 mmHg=0.133 kPa), (83.5±11.0) mmHg, (0.92±0.18)mm and (1 781.7±353.2)cm/s.(2) The participants were divided into high and low level groups according to the median of different SBPs, respectively.The results indicated that CIMT and baPWV were significantly higher in high level groups than in low level groups (all P<0.01). (3) After adjusting for gender and age, the partial correlate analysis showed that the office, visit-to-visit, 24-hour, day-time, night-time SBP positively associated with CIMT and baPWV (all P<0.01). (4) After adjusting for confounding factors, multivariable regression analysis showed that the office, visit-to-visit, 24-hour, day-time, night-time SBP were positively and linearly associated with CIMT and baPWV in total cohort, and standard regression coefficients were 0.157, 0.208, 0.175, 0.169, 0.163, 0.479, 0.420, 0.401, 0.389 and 0.354, respectively.In addition, similar results were observed in male and female participants but there was no significance between night-time SBP and CIMT in female participants. CONCLUSIONS Office, visit-to-visit, 24-hour, day-time, night-time SBP are associated with vascular damages, and the best associations are observed between visit-to-visit SBP and vascular function damage.

Abstract
OBJECTIVE To investigate the medical care resources of acute myocardial infarction (AMI) in Chinese hospitals of different regions and levels. METHODS We selected 115 hospitals in China, including 61 northern hospitals, 54 southern hospitals, 52 eastern hospitals, 26 central hospitals, 37 western hospitals, 79 tertiary hospitals, 36 secondary hospitals, 34 pro vincial-level hospitals, 46 prefectural-level hospitals and 35 county hospitals. From November 2012 to August 2013, we sent questionnaire to the cardiologists in each hospital, to collect related information. RESULTS (1) The number of AMI admitted each year of northern hospital was more than the number of southern hospital (220 (120, 400) cases vs. 220 (80, 350) cases, P=0.033), while number of coronary care unit (CCU), thrombolytic therapy, percutaneous coronary intervention (PCI), primary PCI and coronary artery bypass grafting (CABG) were similar (all P> 0.05). (2) The number of AMI admitted each year of eastern, central and western hospital was 295(150, 501) cases, 175(75, 300) cases and 170(50, 250) cases respectively(P=0.007), with no significant difference among them for setting CCU, carrying out thrombolytic therapy, PCI, primary PCI and CABG (all P>0.05). (3) The total number of the in-patient beds and AMI admitted each year of tertiary hospitals were significantly higher than that in the secondary hospitals(104(70, 152)vs. 47(30, 52), P<0.001) and (300(200, 460)cases vs.80(47, 135)cases, P<0.001) respectively. There was a significant difference between tertiary and secondary hospitals for the number of CCU (97.5% (77/79)and 75.0%(27/36)), PCI (98.7%(78/79)and 27.8%(10/36)), primary PCI (96.2%(76/79)and 22.2%(8/36)), CABG (81.0%(64/79)and 11.1%(4/36)), intra-aortic balloon pump (IABP) (91.1%(72/79) and 13.9%(5/36)) respectively (all P<0.001). (4) There were obvious differences among provincial-level, prefectural-level and country-level hospitals for the admitted AMI patient numbers annually which was 400(250, 600), 232(100, 380)and 80(50, 162)cases, CCU proportion which was 100 %(34/34), 95.7%(44/46) and 74.3%(26/35), thrombolytic therapy proportion which was 88.2%(30/34), 100%(46/46)and 91.4%(32/35), PCI proportion which was 100%(34/34), 89.1%(41/46)and 37.1%(13/35), primary PCI proportion which was 100%(34/34), 84.8%(39/46)and 31.4%(11/35), CABG proportion which was 97.1%(33/34), 67.4%(31/46) and 11.4%(4/35)respectively (P<0.01 or 0.05) . CONCLUSIONS Different regional hospitals have no significant difference in number of CCU and reperfusion therapies, while there is a big difference on medical care resources of AMI between different-level hospitals, which may affect the diagnosis and treatment effect of patients with AMI.

Abstract
Objective: To investigate the hospital costs and related influencing factors in patients with acute poisoning. Methods: A retrospective analysis was performed for the general status and hospital costs of 373 patients with acute poisoning who were admitted to The Second Affiliated Hospital of Wenzhou Medical College from January 2009 to March 2015. The questionnaires were completed, the data were entered into Excel forms, and SPSS 18.0 was used to perform statistical analysis. Results: Among the 373 patients, 44.8% committed suicide and 31.1% were poisoned by accidental contact; 42.6% were poisoned by pesticides, and 32.7% were poisoned by drugs. After treatment, 64.1% achieved improvements, whereas 1.3% died. The highest hospital cost reached 62 710.26 RMB, and the lowest was 64.64 RMB (median 4 328 RMB) . The patients with an older age and a longer length of hospital stay tended to have higher hospital costs; the patients who underwent catharsis, mechanical ventilation, and blood purification and were admitted to the intensive care unit had relatively high hospital costs. Conclusion: The patients with acute poisoning have high hospital costs. Poisoning caused by pesticides and drugs should be prevented and treated with priority, so as to reduce the heavy economic burden caused by acute poisoning.
