Abstract
BACKGROUND The sympathoadrenergic system and its major effector PKA (protein kinase A) are activated to maintain cardiac output coping with physiological or pathological stressors. If and how PKA plays a role in physiological cardiac hypertrophy (PhCH) and pathological CH (PaCH) are not clear. METHODS Transgenic mouse models expressing the PKA inhibition domain (PKAi) of PKA inhibition peptide alpha (PKIalpha)-green fluorescence protein (GFP) fusion protein (PKAi-GFP) in a cardiac-specific and inducible manner (cPKAi) were used to determine the roles of PKA in physiological CH during postnatal growth or induced by swimming, and in PaCH induced by transaortic constriction (TAC) or augmented Ca2+ influx. Kinase profiling was used to determine cPKAi specificity. Echocardiography was used to determine cardiac morphology and function. Western blotting and immunostaining were used to measure protein abundance and phosphorylation. Protein synthesis was assessed by puromycin incorporation and protein degradation by measuring protein ubiquitination and proteasome activity. Neonatal rat cardiomyocytes (NRCMs) infected with AdGFP (GFP adenovirus) or AdPKAi-GFP (PKAi-GFP adenovirus) were used to determine the effects and mechanisms of cPKAi on myocyte hypertrophy. rAAV9.PKAi-GFP was used to treat TAC mice. RESULTS (1) cPKAi delayed postnatal cardiac growth and blunted exercise-induced PhCH; (2) PKA was activated in hearts after TAC due to activated sympathoadrenergic system, the loss of endogenous PKIα (PKA inhibition peptide α), and the stimulation by noncanonical PKA activators; (3) cPKAi ameliorated PaCH induced by TAC and increased Ca2+ influxes and blunted neonatal rat cardiomyocyte hypertrophy by isoproterenol and phenylephrine; (4) cPKAi prevented TAC-induced protein synthesis by inhibiting mTOR (mammalian target of rapamycin) signaling through reducing Akt (protein kinase B) activity, but enhancing inhibitory GSK-3α (glycogen synthase kinase-3α) and GSK-3β signals; (5) cPKAi reduced protein degradation by the ubiquitin-proteasome system via decreasing RPN6 phosphorylation; (6) cPKAi increased the expression of antihypertrophic atrial natriuretic peptide (ANP); (7) cPKAi ameliorated established PaCH and improved animal survival. CONCLUSIONS Cardiomyocyte PKA is a master regulator of PhCH and PaCH through regulating protein synthesis and degradation. cPKAi can be a novel approach to treat PaCH.

Abstract
Corneal diseases are prevalent eye conditions in China, and the lack of effective treatment in the short term can lead to blindness. However, delivering drugs to the cornea safely and effectively poses a significant challenge due to the presence of ocular barriers and clearance mechanisms. Conventional drug delivery methods exhibit low bioavailability, making it difficult to achieve therapeutic effects. Microneedles, with their ability to penetrate ocular surface barriers effectively, offer a low-invasive and highly promising drug delivery technology. This article introduces the main delivery barriers on the ocular surface, classifies microneedles, and highlights the latest developments in the treatment of corneal diseases. Finally, the potential challenges of applying microneedle delivery systems to the ocular surface are analyzed, aiming to provide insights for the clinical application of microneedles in corneal diseases.

Abstract
PURPOSE The Coexpression Extrapolation (COXEN) gene expression model with chemotherapy-specific scores [for methotrexate, vinblastine, adriamycin, cisplatin (ddMVAC) and gemcitabine/cisplatin (GC)] was developed to identify responders to neoadjuvant chemotherapy (NAC). We investigated RNA-based molecular subtypes as additional predictive biomarkers for NAC response, progression-free survival (PFS), and overall survival (OS) in patients treated in S1314. EXPERIMENTAL DESIGN A total of 237 patients were randomized between four cycles of ddMVAC (51%) and GC (49%). On the basis of Affymetrix transcriptomic data, we determined subtypes using three classifiers: TCGA (k = 5), Consensus (k = 6), and MD Anderson (MDA; k = 3) and assessed subtype association with path response to NAC and determined associations with COXEN. We also tested whether each classifier contributed additional predictive power when added to a model based on predefined stratification (strat) factors (PS 0 vs. 1; T2 vs. T3, T4a). RESULTS A total of 155 patients had gene expression results, received at least three of four cycles of NAC, and had pT-N response based on radical cystectomy. TCGA three-group classifier basal-squamous (BS)/neuronal, luminal (Lum), Lum infiltrated, and GC COXEN score yielded the largest AUCs for pT0 (0.59, P = 0.28; 0.60, P = 0.18, respectively). For downstaging ( CONCLUSIONS The Consensus classifier, based in part on the TCGA and MDA classifiers, modestly improved prediction for pathologic downstaging but subtypes were not associated with PFS or OS.

Abstract
BACKGROUND Presently, global aging has become increasingly serious, whereas the health concerns brought by aging have become a public issue that warrants an urgent solution from all countries across the world. Therefore, this research paper discusses the influence of neighborhood health on elderly individuals' health, and extending a realistic basis for the other economies to improve the neighborhood environment and promote the health of the elderly. METHODS Based on the data of CHARLS2018, this research paper adopts the samples that fulfill the study requirements (N = 7326). we constructed a comprehensive research framework integrating oprobit regression model, heterogeneity analysis, conditional mixed process(CMP)robustness testing, Furthermore, the KHB decomposition method is implemented to ascertain the influential mechanism of NMH and NPH on the mental- and physical health of elderly persons. RESULTS The oprobit regression model analysis indicates that NMH 0.434 and NPH 0.550 exert positive influences on the elderly's mental- and physical health. Meanwhile, the effects of conditional mixed process on NMH and NPH stand at 0.381 and4.372, which are different from the oprobit regression results; thereby, indicating the existence of endogeneity. Afterward, KHB mediating effect confirms that Internet use, gift reciprocity, and charity activity contribute 30.21% and 16.83% to mental- and physical health, respectively. CONCLUSIONS Firstly, the NMH and NPH demonstrate a positive influence on the mental- and physical health of the elder population. However, there exist heterogeneous differences. Secondly, the conditional mixed process deals with the endogeneity of NMH and NPH. Thirdly, social integration, social interaction, and social engagement serve as significant transmission mechanisms for the influences of NMH and NPH on the health of elderly persons.

Abstract
Hyaluronic acid-binding protein (HABP4) plays important roles in regulating cell cycle and apoptosis. However, its functions in regulating cell apoptosis remain unclear. To reveal the effects of HABP4 on cell proliferation, cell cycle and apoptosis, the HABP4 sequence was cloned, and we investigated the gain and loss functions of HABP4 in goat turbinate bone cells. Our results showed that a 1,496-bp HABP4 sequence was cloned successfully. The interference effect of siRNA1 on HABP4 was the strongest, reducing its mRNA expression level by 83%, decreasing the cells in the G0/G1 and S phases of the cell cycle and inhibiting cell growth and apoptosis. The overexpression of HABP4 produced contrasting results. Furthermore, an HABP4 knockdown caused the up-regulated expression of genes associated with apoptosis, including Bcl-2 and BCL2L11, but the down-regulation of Caspase3, Caspase7, Bax, PARP1, SOCS2 and P53 mRNA levels. Additionally, HABP4 overexpression significantly up-regulated the expression levels of Bax, Caspase3, Caspase7, BCL2L11, P53, SOCS2 and PARP1. However, the expression of Bcl-2 was down-regulated. These data provide an important foundation for further in-depth studies of HABP4 functions.

Abstract
PURPOSE/OBJECTIVE(S) Recent studies indicate that the novel lymphocyte-C-reactive protein ratio (LCR) is strongly associated with the survival of various tumors, but its prognostic value in nasopharyngeal carcinoma (NPC) is understudied. This study aimed to explore the relationship between the LCR and overall survival (OS) in NPC and to develop a predictive model. MATERIALS/METHODS A total of 841 NPC patients received concurrent chemoradiotherapy (CCRT) were retrospectively enrolled and randomly divided into training cohort (n = 589) and validation cohort (n = 252). Univariate and multivariate Cox analyses were performed to identify variables associated with OS and construct a predictive nomogram. The predictive accuracy of the nomogram was evaluated and independently validated. RESULTS The LCR score differentiated NPC patients into two groups with distinct prognoses (HR = 0.53; 95% CI: 0.32-0.89, P = 0.014). Multivariate analysis showed that age, T stage, N stage, EBV-DNA status, and LCR score were independently associated with OS and a predictive nomogram was developed. The nomogram had a good performance for the prediction of OS [C-index = 0.770 (95% CI: 0.675-0.864)] and outperformed the traditional staging system [C-index = 0.589 (95% CI: 0.385-0.792)]. The results were internally validated using an independent cohort. CONCLUSION The novel nutrition-inflammation marker of LCR could serve as a simplified, affordable, easy-to-obtain, non-invasive, and readily promotive prognostic marker for NPC patients received CCRT, and the LCR-based prognostic nomogram outperformed the conventional staging system in terms of predictive power.

Abstract
The transcription factor ThPOK (encoded by Zbtb7b) is well known for its role as a master regulator of CD4 lineage commitment in the thymus. Here, we report an unexpected and critical role of ThPOK as a multifaceted regulator of myeloid lineage commitment, differentiation and maturation. Using reporter and knockout mouse models combined with single-cell RNA-sequencing, progenitor transfer and colony assays, we show that ThPOK controls monocyte-dendritic cell versus granulocyte lineage production during homeostatic differentiation, and serves as a brake for neutrophil maturation in granulocyte lineage-specified cells through transcriptional regulation of lineage-specific transcription factors and RNA via altered messenger RNA splicing to reprogram intron retention.

Abstract
BACKGROUND Psoriasis is a chronic, complicated, and recurrent inflammatory skin disease, whose precise molecular mechanisms need to be further explored. The lncRNA bladder cancer-associated transcript 1 (BLACAT1) is aberrantly expressed in many cancers and associated with cellular hyperproliferation and may play a role in the pathogenesis of psoriasis. Thus, this study aimed at identifying the primary mechanism associated with BLACAT1 in psoriasis pathogenesis. MATERIALS AND METHODS Quantitative reverse transcriptase polymerase chain reaction (qRT-PCR) was performed to detect the expression of BLACAT1 in psoriasis tissues. Cell proliferation and apoptosis were assessed using cell counting kit-8 and apoptosis assays, respectively. In vivo experiments and histopathological examinations were performed to investigate the effects of BLACAT1 on psoriasis. Dual-luciferase Reporter and RNA immunoprecipitation assays were used to evaluate the relationship among BLACAT1 and miR-149-5p and AKT1. RESULTS BLACAT1 was upregulated in psoriasis tissues. Overexpression exacerbated the clinical manifestation of psoriasis and increased the epidermal thickness in imiquimod-induced mice. BLACAT1 could promote proliferation and inhibit apoptosis of keratinocytes. Further studies demonstrated that BLACAT1 positively regulated AKT1 expression, functioning as a competing endogenous RNA (ceRNA) by sponging miR-149-5p. CONCLUSIONS The combination of lncRNA BLACAT1 and miR-149-5p regulates AKT1 expression and promotes psoriasis formation thus may provide a new direction for psoriasis treatment.

Abstract
Purpose This study aimed to evaluate the effectiveness of smartphone otoscope telemedicine in the rural medical consortium in East China in the COVID-19 era. Methods This prospective study was conducted within a rural medical consortium that provides health care services by integrating medical resources in the same area. When a patient visited primary health care (PHC) for ear diseases, the PHC provider used a smartphone otoscope to examine the patient's external ear canal and eardrum, and then sent photos or videos of the patient's ear to the otolaryngologist at the lead hospital via WeChat group. The otolaryngologist provided remote diagnosis and management recommendations to the PHC provider. The following data were recorded: age and gender, outpatient diagnosis, disease duration, sides, duration of treatment, telemedicine visits, treatment outcomes, patient satisfaction, and PHC providers' self-evaluation score. Results A total of 83 patients were included in the study, including 43 males and 40 females, with a mean age of 44.6 ± 19.7 years (range 3–83 years). The duration of treatment for these patients was 14.0 (7,14) days. PHC visits were 2.2 ± 1.1 times (range: 1–7 times). Telemedicine visits ranged from 1 to 5, with a mean of 1.8 ± 0.9. Among of patients, 62 (74.7%) were cured, 21 (25.3%) improved, and 0 (0%) were ineffective. Sixty-five patients (78.3%) were very satisfied, 16 (19.3%) patients were somewhat satisfied, and two patients (2.4%) were dissatisfied. Based on the self-reported helpfulness, the primary health care providers assessed telemedicine as very helpful (n = 63, 75.9%), helpful (n = 20, 24.1%), and unhelpful (n = 0, 0%). Conclusions Smartphone otoscope telemedicine in the medical consortium can effectively improve the ability of rural PHC providers to diagnose and treat ear diseases, save time and costs for patients, and improve patient satisfaction.

Abstract
How multipotential cells initiate distinct gene expression programs in response to external cues to instruct cell fate choice remains a fundamental question in biology. Establishment of CD4 and CD8 T cell fates during thymocyte development is critically regulated by T cell receptor (TCR) signals, which in turn control expression of the CD4-determining transcription factor ThPOK. However, the mechanism whereby differential TCR signals are molecularly interpreted to promote or antagonize ThPOK expression, and thereby CD4 versus CD8 lineage fates remains unknown. Here we show, using reverse genetic and molecular approaches that an autonomous, position-independent TCR-sensing switch is embedded within the ThPOK locus. Further, using an in vivo mutagenesis approach, we demonstrate that differential TCR signals are interpreted during lineage commitment by relative binding of EGR, NFAT and Ebox factors to this bistable switch. Collectively our study reveals the central molecular mechanism whereby TCR signaling influences differential lineage choice. Ultimately, these findings may provide an important new tool for skewing T cell fate to treat cancer and autoimmune diseases. Basu Jayati et al. examine how T-cell receptor (TCR) engagement with MHC ligands can contribute toward adoption of CD4 and CD8 cell fates during development. By using an in vivo mutagenesis approach in mice, their results suggest potential mechanisms linking TCR signaling to ThPOK expression and differential immune lineage choice.

Abstract
We improved the optical quality and stability of an exfoliated monolayer (ML) MoSe2 and chemical vapor deposition (CVD)-grown WS2 MLs by encapsulating and sealing them with both top and bottom few-layer h-BN, as tested by subsequent high-temperature annealing up to 873 K and photoluminescence (PL) measurements. These transition-metal dichalcogenide (TMD) MLs remained stable up to this maximum temperature, as seen visually. After the heating/cooling cycle, the integrated photoluminescence (PL) intensity at 300 K in the MoSe2 ML was ∼4 times larger than that before heating and that from exciton and trion PL in the analogous WS2 ML sample was ∼14 times and ∼2.5 times larger at 77 K and the exciton peak was ∼9.5 times larger at 300 K. This is attributed to the reduction of impurities, the lateral expulsion of contamination leading to clean and atomically flat surfaces, and the sealing provided by the h-BN layers that prevents the diffusion of molecules such as trace O2 and H2O to the TMD ML. Stability and optical performance are much improved compared to that in earlier work using top h-BN only, in which the WS2 ML PL intensity decreased even for an optimal gas environment. This complete encapsulation is particularly promising for CVD-grown TMD MLs because they have relatively more charge and other impurities than do exfoliated MLs. These results open a new route for improving the optical properties of TMD MLs and their performance and applications both at room and higher temperatures.

Abstract
BACKGROUND Immune responses, especially type 2 immunity, might be related to the prevalence of thyroid nodules, while the key regulators and potential pathways are remaining largely unknown. In addition, the immune status of individuals could be affected by mixed metabolic background. Herein our aim was to investigate the adjusted association between ultrasound-diagnosed low risk thyroid nodules and immune responses, excluding the interference of metabolic effects on immunity. METHODS We retrospectively enrolled 1764 subjects who underwent a thorough thyroid ultrasound examination. To eliminate the interference of confounders, we used propensity score matching (PSM) to match age, gender, cigarette smoking and alcohol drinking, parameters that are related with metabolic syndrome (MetS). Then the potential effectors of immune responses involved in the laboratorial assays were evaluated. Binary logistic regression analysis was used to assess the independent predictors of thyroid nodules in a multivariate manner. RESULTS The 1172 subjects were remained after PSM, and differences of demographic background between subjects with and without thyroid nodules were eliminated. Metabolic parameters comprising blood pressure, fasting blood glucose, total cholesterol, triglyceride, high-density lipoprotein, low-density lipoprotein and serum uric acid were shown no significant difference between post-PSM subjects with and without thyroid nodules. Among the biochemistry and hematological parameters, white blood cell count and the positive rate of eosinophil percentage were increased in subjects with thyroid nodules than in those without thyroid nodules. In contrast, the positive rate of basophil percentage was lower in subjects with thyroid nodules than in those without thyroid nodules. In addition, the thyroid function test results showed that subjects with thyroid nodules had higher positive rates of antithyroglobulin antibody (TgAb) and antithyroid peroxidase antibody (TPOAb) than subjects without thyroid nodules. The logistic regression analysis indicated that the positive value of TgAb as well as high level of white blood cell count and BMI could serve as independent risk factors of thyroid nodules. CONCLUSIONS The type 2 immune responses mediated by increased level of eosinophils, along with positive value of TgAb and TPOAb were associated with the presence of thyroid nodules. In addition, the potential role of basophils in protecting against thyroid nodules and the pathogenesis of immune-metabolic status remains to be elucidated.

Abstract
BACKGROUND The burden of influenza is mostly felt by employees and employers because of increased absenteeism rates, loss of productivity and associated direct costs. Even though interventions against influenza among working adults are effective, patronage and compliance to these measures especially vaccination are low compared to other risk groups. AIMS This study was aimed to assess evidence of economic evaluations of interventions against influenza virus infection among workers or in the workplace setting. METHODS The Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) reporting guideline for systematic reviews was followed. Three databases, PubMed, Web of Science and EconLit, were searched using keywords to identify relevant articles from inception till 25 October 2020. Original peer-reviewed papers that conducted economic evaluations of influenza interventions using cost-benefit, cost-effectiveness or cost-utility analysis methods focused on working-age adults or work settings were eligible for inclusion. Two independent teams of co-authors extracted and synthesized data from identified studies. RESULTS Twenty-four articles were included: 21 were cost-benefit analyses and 3 examined cost-effectiveness analyses. Two papers also presented additional cost-utility analysis. Most of the studies were pharmaceutical interventions (n = 23) primarily focused on vaccination programs while one study was a non-pharmaceutical intervention examining the benefit of paid sick leave. All but two studies reported that interventions against influenza virus infection at the workplace were cost-saving and cost-effective regardless of the analytic approach. CONCLUSIONS Further cost-effectiveness research in non-pharmaceutical interventions against influenza in workplace settings is warranted. There is a need to develop standardized methods for reporting economic evaluation methods to ensure comparability and applicability of future research findings.

Abstract
The transcription factor ThPOK (encoded by the Zbtb7b gene) controls homeostasis and differentiation of mature helper T cells, while opposing their differentiation to CD4+ intraepithelial lymphocytes (IELs) in the intestinal mucosa. Thus CD4 IEL differentiation requires ThPOK transcriptional repression via reactivation of the ThPOK transcriptional silencer element (SilThPOK). In the present study, we describe a new autoregulatory loop whereby ThPOK binds to the SilThPOK to maintain its own long-term expression in CD4 T cells. Disruption of this loop in vivo prevents persistent ThPOK expression, leads to genome-wide changes in chromatin accessibility and derepresses the colonic regulatory T (Treg) cell gene expression signature. This promotes selective differentiation of naive CD4 T cells into GITRloPD-1loCD25lo (Triplelo) Treg cells and conversion to CD4+ IELs in the gut, thereby providing dominant protection from colitis. Hence, the ThPOK autoregulatory loop represents a key mechanism to physiologically control ThPOK expression and T cell differentiation in the gut, with potential therapeutic relevance.

Abstract
Chemical vapor deposition (CVD)-grown flakes of high-quality monolayers of WS2 can be stabilized at elevated temperatures by encapsulation with several layer hexagonal boron nitride (h-BN), but to different degrees in the presence of ambient air, flowing N2, and flowing forming gas (95% N2, 5% H2). The best passivation of WS2 at elevated temperature occurs for h-BN-covered samples with flowing N2 (after heating to 873 K), as judged by optical microscopy and photoluminescence (PL) intensity after a heating/cooling cycle. Stability is worse for uncovered samples, but best with flowing forming gas. PL from trions, in addition to that from excitons, is seen for covered WS2 only for forming gas, during cooling below ∼323 K; the trion has an estimated binding energy of ∼28 meV. It might occur because of doping level changes caused by charge defect generation by H2 molecules diffusing between the h-BN and the SiO2/Si substrate. The decomposition of uncovered WS2 flakes in air suggests a dissociation and chemisorption energy barrier of O2 on the WS2 surface of ∼1.6 eV. Fitting the high-temperature PL intensities in air gives a binding energy of a free exciton of ∼229 meV.

Abstract
BACKGROUND Phthalates, which are used as excipients of drugs, have been related to adverse reproductive outcomes. However, the relationships between medication use and phthalate exposure among women undergoing in vitro fertilization (IVF) have not been studied. OBJECTIVE To investigate the associations between the medication intake and phthalate metabolites in urine and follicular fluid (FF). METHOD Eight phthalate metabolites were measured in urine and FF samples from 274 women undergoing IVF using liquid chromatography-tandem mass spectrometry. Information on recent medication intake was obtained via interview by trained staff. We constructed generalized linear regression models to examine the associations of medication intake with phthalate metabolite concentrations and dose-response relationships between the number of medicines used and metabolite concentrations in two matrices. RESULTS Four of 10 drugs were used by more than 10% of the participants, including vitamins (23.0%), traditional Chinese medicine (TCM, 22.3%), antioxidants (12.4%) and amoxicillin (10.2%). Participants who had used TCM had 26.0% (95% CI: 0.0, 58.8%), 32.6% (95% CI: 4.2, 68.8%) and 32.3% (95% CI: 2.6, 70.6%) higher urinary mono-n-butyl phthalate (MBP), mono(2-ethyl-5-hydroxyhexyl) phthalate (MEHHP) and mono(2-ethyl-5-oxohexyl) phthalate (MEOHP) concentrations, respectively, than those who had not. Antioxidant intake was associated with a 30.6% (95% CI: -48.5, -6.6%) decrease in the urinary MBP concentration. Compared with non-users, women who reported the use of medicines had 53.2% (95% CI: 2.7, 128.5%) higher concentrations of MMP and a 37.7% (95% CI: -60.7, -1.5%) lower level of MBP in FF, respectively. CONCLUSION Our data suggest that the intake of some medications may increase phthalate exposure among women undergoing IVF.

Abstract
Polychlorinated biphenyls (PCBs), as persistent organic pollutants, are environmental endocrine-disrupting chemicals (EDCs). We aim to investigate the effects of prepubertal exposure to PCBs on the reproductive development and expression and regulation of related genes in rats. Female rats were treated with Aroclor-1221 (A-1221) (4 mg/kg/day, 0.4 mg/kg/day) or castor oil daily from postnatal day (PND) 28 for 2 weeks by gavage. Morphological, histological, hormonal, and biochemical parameters were studied. Lower weight and relative weight of hypothalamus, earlier puberty onset, a longer length of the estrous cycle, lower serum estradiol and progesterone levels, accelerated ovarian folliculogenesis, and higher apoptotic index in the ovary were found. The in vitro fertilization study showed a lower fertilization rate and cleavage rate. The genetic study revealed higher expression of Kiss-1 mRNA and lower expression of GnRH mRNA in the hypothalamus and higher expression of AMH mRNA and lower expression of C-myc mRNA in the ovary. These confirmed the reproductive damage of A-1221 in rats.

Abstract
BACKGROUND There is no clinically applicable prognostic model designed for patients with de novo metastatic nasopharyngeal carcinoma (mNPC) treated with chemotherapy followed by locoregional radiotherapy (LRRT). We sought to develop a predictive tool of overall survival for individualized prediction and risk stratification in this heterogeneous patient population. PATIENTS AND METHODS A total of 244 eligible patients with de novo mNPC, who were treated with platinum-based first-line chemotherapy followed by LRRT, were included in this retrospective study. We divided patients into the training and validation sets based on the date of initial treatment, with 152 patients treated between 2008 and 2013 comprising the training set for model development and 92 patients treated at a later time (2014 to 2015) forming the validation set. We applied Cox proportional hazards model to examine factors associated with overall survival (OS). We developed and subsequently validated a prognostic model to predict OS. We assessed the performance of this prognostic model and stratified patients based on prognostic scores obtained from this proposed model. RESULTS The median OS of the entire cohort was 60.9 months. C-creative protein, number of metastatic sites, liver metastasis, post-treatment Epstein-Barr virus DNA, and response of metastasis were significantly associated with OS. A prognostic model for individual survival prediction was developed and graphically represented as a nomogram. The model showed favorable discrimination (C-index: 0.759), predictive accuracy [time dependent area under the curve (tAUC) at 5 years: 0.800], and calibration, and was further validated in an independent dataset. A risk stratification derived from the model can stratify these patients into three prognostic subgroups with significantly different survival. CONCLUSION We developed and validated a prognostic model that exhibited adequate performance in individualized prediction and risk stratification for patients with de novo mNPC treated with chemotherapy followed by LRRT.

Abstract
Epidemiological studies have suggested that phthalate exposures were associated with adverse reproductive outcomes, such as low oocyte yield and reduced embryo quality, but the underlying mechanisms remained largely unknown. Oxidative stress may be a potential contributor to phthalate-induced adverse reproductive outcomes. To explore the associations between phthalate exposure and levels of oxidative stress among women seeking in vitro fertilization (IVF), we measured the concentrations of eight phthalate metabolites and biomarkers of oxidative stress, including 8-hydroxy-2'-deoxyguanosine (8-OHdG), malondialdehyde (MDA), and total antioxidant capacity (TAC), in follicular fluid (FF) samples collected from 332 women. Multivariable linear regression models were used to assess the associations between phthalate metabolites and biomarkers of oxidative stress in FF samples. The concentrations of most tested phthalate metabolites were positively associated with the 8-OHdG levels. The metabolites of di-(2-ethylhexyl) phthalate (DEHP) were inversely associated with the TAC levels. The concentrations of mono(2-ethyl-5-hydroxyhexyl) phthalate (MEHHP) and mono(2-ethyl-5-oxohexyl) phthalate (MEOHP) were positively associated with the MDA levels. Our results revealed a positive association between phthalate metabolites and oxidative stress levels in FF, while more toxicological and epidemiological studies are required to confirm our findings.

Abstract
We investigate the impact of the photorefractive effect on lithium niobate integrated quantum photonic circuits dedicated to continuous variable on-chip experiments. The circuit main building blocks, i.e. cavities, directional couplers, and periodically poled nonlinear waveguides, are studied. This work demonstrates that photorefractivity, even when its effect is weaker than spatial mode hopping, might compromise the success of on-chip quantum photonics experiments. We describe in detail the characterization methods leading to the identification of this possible issue. We also study to which extent device heating represents a viable solution to counter this effect. We focus on photorefractive effect induced by light at 775 nm, in the context of the generation of non-classical light at 1550 nm telecom wavelength.

Abstract
AIMS To explore whether there is a different strength of association between self-rated health and all-cause mortality in people with type 2 diabetes across three country groupings: nine countries grouped together as 'established market economies'; Asia; and Eastern Europe. METHODS The ADVANCE trial and its post-trial follow-up were used in this study, which included 11 140 people with type 2 diabetes from 20 countries, with a median follow-up of 9.9 years. Self-rated health was reported on a 0-100 visual analogue scale. Cox proportional hazard models were fitted to estimate the relationship between the visual analogue scale score and all-cause mortality, controlling for a range of demographic and clinical risk factors. Interaction terms were used to assess whether the association between the visual analogue scale score and mortality varied across country groupings. RESULTS The visual analogue scale score had different strengths of association with mortality in the three country groupings. A 10-point increase in visual analogue scale score was associated with a 15% (95% CI 12-18) lower mortality hazard in the established market economies, a 25% (95% CI 21-28) lower hazard in Asia, and an 8% (95% CI 3-13) lower hazard in Eastern Europe. CONCLUSIONS Self-rated health appears to predict 10-year all-cause mortality for people with type 2 diabetes worldwide, but this relationship varies across groups of countries.

Abstract
OBJECTIVE Our study aimed to investigate the expression pattern, clinicopathological feature and prognostic role of miR-1181 in nasopharyngeal carcinoma (NPC), and to determine the functional effects and potential mechanism of miR-1181 in NPC. PATIENTS AND METHODS The expression levels of miR-1181 were determined in NPC tissues and cell lines by RT-PCR. The clinical data were interpreted by chi-square test, univariate analysis, and multivariate analysis. The effect of PVT1 on proliferation was evaluated by CCK-8 and colony formation assays, and migration and invasion ability were evaluated by transwell and wound-healing assays. The association between miR-1181 and Wnt/β-catenin pathway was analyzed by Western blot. RESULTS We found that miR-1181 expression was significantly down-regulated in both NPC tissues and cell lines. Low expression of miR-1181 was significantly associated with N stage (p=0.013), clinical stage (p=0.037) and grade (p=0.033). Clinical assays showed that patients with low miR-1181 expression had shorter overall survival time than those with high miR-1181 expression (p=0.0007). Multivariate analysis revealed that miR-1181 expression was independently associated with the overall survival. Functional investigations indicated that overexpression of miR-1181 suppressed NPC cells proliferation, migration and invasion. Mechanistically, forced miR-1181 expression suppressed the activity of Wnt/β-catenin pathway. CONCLUSIONS Our findings proved that miR-1181 may serve as a candidate prognostic biomarker and target for new therapies in NPC patients.

Abstract
BACKGROUND Phthalate metabolites in follicular fluid (FF) may negatively affect normal folliculogenesis; however, the predictors of phthalate metabolite concentrations in urine and FF and relationships between urine and FF phthalate metabolite concentrations among women undergoing in vitro fertilization (IVF) are poorly understood. OBJECTIVE To investigate predictors of phthalate metabolites in urine and FF and correlations between urine and FF phthalate metabolite concentrations among women undergoing IVF. METHOD We recruited 305 women seeking infertility treatment at a reproductive center in Wuhan, China, from October to November 2016. Information regarding demographic characteristics, personal care product use and plastic material contact was obtained through direct interviews. Concentrations of 8 phthalate metabolites in urine and FF samples were measured using high-performance liquid chromatography and tandem mass spectrometry. Associations regarding metabolite concentrations in urine and FF samples were analysed by Spearman's correlation and linear regression. Generalized linear regression was used to examine potential predictors of phthalate metabolite concentrations in urine and FF. RESULTS Weak to moderate associations between urine and FF samples were found for monoethyl phthalate (MEP) and mono(2-ethyl-5-oxohexyl) phthalate (MEOHP) (correlation coefficient: MEP, 0.350; MEOHP, 0.377); no associations were observed for other metabolites. The predictive powers of urinary metabolite concentrations in determining FF metabolite concentrations were uniformly low, with R2 ≤ 0.113. Body mass index (BMI) and educational level were inversely associated with the urinary concentrations of certain metabolites. Higher household income, intake of bottled drinks within 48 h, and use of shower gel and soap were frequently associated with higher urinary metabolite concentrations. BMI, higher household income and use of disposable plastic cups within 48 h were associated with higher metabolite concentrations in FF. CONCLUSION Phthalate metabolite concentrations in urine and FF vary according to sociodemographic characteristics and lifestyle factors. Phthalate metabolite concentrations in urine may not be appropriate for estimating ovary phthalate exposure.

Abstract
BACKGROUND Phthalate exposure was reported to induce defects in ovarian function, and further influence embryo development and pregnancy outcomes. However, the data about the associations of phthalates with intermediate and pregnancy outcomes of in vitro fertilization (IVF) cycles are scarce in the Chinese population. METHODS A total of 663 women receiving IVF/intracytoplasmic sperm injection (ICSI) treatments in our center were enrolled in this analysis. They provided one urine sample on the day of oocyte retrieval. We measured urinary concentrations of eight phthalate metabolites. Generalized linear models were used to analyze the associations of urinary phthalate metabolites with ovarian response, fertilization, early embryo development, and pregnancy outcomes. RESULTS Among all the phthalate metabolites, mono-n-butyl phthalate (MBP) had the highest urinary concentration with a median level of 101.51 μg/g creatinine (Cr). MBP concentration was inversely associated with normal fertilization odds (overall P-trend < 0.01). There was a significant correlation of monoethyl phthalate (MEP) with decreased odds of normal fertilization in medium-concentration group compared to low-concentration group (overall P-trend = 0.02). No significant associations of metabolite concentrations with the odds of good-quality embryos on day 3 or blastocyst formation were found. Monomethyl phthalate (MMP) and MEP in medium-concentration group reduced 22.4% (95% CI: 0.64-0.94, overall P-trend = 0.04) and 21.9% (95% CI: 0.64-0.95, overall P-trend = 0.05) of the odds to gain good-quality blastocyst compared to low-concentration group. The eight phthalate metabolites were not correlated to clinical pregnancy rate, live birth rate, or early miscarriage rate. There was no significant association of di (2-ethylhexyl) phthalate (DEHP) metabolites observed with any clinical outcomes in the total population. After excluding male infertility, mono (2-ethyl-5-hydroxyhexyl) phthalate (MEHHP) in medium-concentration group turned to be associated with a higher number of retrieved oocytes (overall P-trend = 0.04), whereas mono (2-ethyl-5-oxohexyl) phthalate (MEOHP) in medium-concentration group was associated with a lower odds of normal fertilization compared to low-concentration group (overall P-trend = 0.02). CONCLUSIONS Urinary MBP concentration was much higher compared to other phthalate metabolites in this cohort of Chinese IVF/ICSI women, and also higher than it was reported by studies in other countries. MBP showed adverse impacts on fertilization. MMP and MEP could affect blastocyst quality, but not embryo quality on day 3. DEHP metabolites didn't show consistent reproductive toxicities as demonstrated in previous studies.

Abstract
AIM To investigate the differential effects of endometrial preparation approaches, natural cycle (NC) and hormone replacement therapy (HRT), on the endometrial hormone conditions in patients with recurrent pregnancy loss (RPL). METHODS 42 RPL patients were recruited, and a self-controlled trial was conducted to compare the effectiveness of NC to HRT on the same patient. The estradiol (E2) and progesterone (P) levels in both serum and endometrial tissue were measured in NC and HRT, respectively. Meanwhile, the expression levels of endometrial progesterone receptor A (PRA) and progesterone receptor B (PRB) were also compared between NC and HRT cycles during the window of receptivity. All statistical analyses were performed using GraphPad Prism 5, and data were averaged across subjects and tested for significance by pair-samples t-test. RESULTS Hormone replacement slightly decreased serum E2 and P levels (0.9- and 0.8-fold in average, respectively), significantly elevated endometrial E2 and P (2.1- and 14.5-fold in average, respectively), and reduced endometrial E2/P ratio (0.34-fold in average) compared to the NC condition. However, no correlation was found between serum and endometrial hormone concentrations. Further, the PRA/PRB ratios of both stromal and glandular cells were comparable between HRT and NC conditions, even though stromal PRA expression was slightly elevated by HRT compared to NC (1.63±0.96 vs 1.18±0.99, p =.0173). CONCLUSION The effects of HRT for endometrial preparation are similar or slightly superior to NC in RPL patients.

Abstract
ThPOK is a "master regulator" of T lymphocyte lineage choice, whose presence or absence is sufficient to dictate development to the CD4 or CD8 lineages, respectively. Induction of ThPOK is transcriptionally regulated, via a lineage-specific silencer element, SilThPOK. Here, we take advantage of the available genome sequence data as well as site-specific gene targeting technology, to evaluate the functional conservation of ThPOK regulation across mammalian evolution, and assess the importance of motif grammar (order and orientation of TF binding sites) on SilThPOK function in vivo. We make three important points: First, the SilThPOK is present in marsupial and placental mammals, but is not found in available genome assemblies of nonmammalian vertebrates, indicating that it arose after divergence of mammals from other vertebrates. Secondly, by replacing the murine SilThPOK in situ with its marsupial equivalent using a knockin approach, we demonstrate that the marsupial SilThPOK supports correct CD4 T lymphocyte lineage-specification in mice. To our knowledge, this is the first in vivo demonstration of functional equivalency for a silencer element between marsupial and placental mammals using a definitive knockin approach. Finally, we show that alteration of the position/orientation of a highly conserved region within the murine SilThPOK is sufficient to destroy silencer activity in vivo, demonstrating that motif grammar of this "solid" synteny block is critical for silencer function. Dependence of SilThPOK function on motif grammar conserved since the mid-Jurassic age, 165 Ma, suggests that the SilThPOK operates as a silenceosome, by analogy with the previously proposed enhanceosome model.

Abstract
RATIONALE PKA (Protein Kinase A) is a major mediator of β-AR (β-adrenergic) regulation of cardiac function, but other mediators have also been suggested. Reduced PKA basal activity and activation are linked to cardiac diseases. However, how complete loss of PKA activity impacts on cardiac physiology and if it causes cardiac dysfunction have never been determined. OBJECTIVES We set to determine how the heart adapts to the loss of cardiomyocyte PKA activity and if it elicits cardiac abnormalities. METHODS AND RESULTS (1) Cardiac PKA activity was almost completely inhibited by expressing a PKA inhibitor peptide in cardiomyocytes (cPKAi) in mice; (2) cPKAi reduced basal phosphorylation of 2 myofilament proteins (TnI [troponin I] and cardiac myosin binding protein C), and one longitudinal SR (sarcoplasmic reticulum) protein (PLB [phospholamban]) but not of the sarcolemmal proteins (Cav1.2 α1c and PLM [phospholemman]), dyadic protein RyR2, and nuclear protein CREB (cAMP response element binding protein) at their PKA phosphorylation sites; (3) cPKAi increased the expression of CaMKII (Ca2+/calmodulin-dependent kinase II), the Cav1.2 β subunits and current, but decreased CaMKII phosphorylation and CaMKII-mediated phosphorylation of PLB and RyR2; (4) These changes resulted in significantly enhanced myofilament Ca2+ sensitivity, prolonged contraction, slowed relaxation but increased myocyte Ca2+ transient and contraction amplitudes; (5) Isoproterenol-induced PKA and CaMKII activation and their phosphorylation of proteins were prevented by cPKAi; (6) cPKAi abolished the increases of heart rate, and cardiac and myocyte contractility by a β-AR agonist (isoproterenol), showing an important role of PKA and a minimal role of PKA-independent β-AR signaling in acute cardiac regulation; (7) cPKAi mice have partial exercise capability probably by enhancing vascular constriction and ventricular filling during β-AR stimulation; and (8) cPKAi mice did not show any cardiac functional or structural abnormalities during the 1-year study period. CONCLUSIONS PKA activity suppression induces a unique Ca2+ handling phenotype, eliminates β-AR regulation of heart rates and cardiac contractility but does not cause cardiac abnormalities.

Abstract
OBJECTIVE To explore whether follicular fluid (FF) concentrations of phthalate metabolites are associated with levels of intrafollicular reproductive hormones in women undergoing in vitro fertilization. DESIGN Cross-sectional study. SETTING University-affiliated reproductive medicine center. PATIENT(S) A total of 194 women each contributed one FF sample at oocyte retrieval. INTERVENTION(S) FF aspirates from individual follicles (≥18 mm in diameter) were collected. We measured eight phthalate metabolites and four ovarian hormones in the FF samples. MAIN OUTCOME MEASURE(S) Per-follicle E2, P, total T, and antimüllerian hormone (AMH) concentrations. RESULT(S) Most phthalate metabolites were highly detected in FF samples. We observed a dose-response relationship between increasing monomethyl phthalate (MMP) tertiles and lower E2, P, and T levels. Women in the third tertile of MMP had decreases of 34.23%, 9.44 ng/L, and 23.28% in E2, P, and T, respectively, compared with women in the first tertile. Tertiles of monoethyl phthalate and the percentage of di(2-ethylhexyl) phthalate) metabolites excreted as mono(2-ethylhexyl) phthalate were inversely associated with P. We also identified a negative relationship between monobenzyl phthalate tertiles and AMH. In addition, positive correlations between some of the phthalate metabolites and ovarian hormones were detected. CONCLUSION(S) FF concentrations of certain phthalate metabolites were associated with altered levels of intrafollicular reproductive hormones, which raises concern over a potential deleterious effect of environmental phthalate exposure on the endocrine capacity and viability of theca and granulosa cells.

Abstract
OBJECTIVES The mcr-1 gene is the first reported plasmid-mediated colistin resistance gene. It has caused worldwide concern about the colistin resistance in Gram-negative bacteria. The aim of this research was to study the impact of mcr-1 on the selection of high-level colistin resistance (HLCR) mutations in Escherichia coli and Klebsiella pneumoniae. METHODS We detected the HLCR mutation rates of Enterobacteriaceae strains (K. pneumoniae XH209, KP10, and E. coli Q3, ATCC 25922) and their transformants harbouring the mcr-1 gene. Further analysis of the HLCR mutants was conducted by sequencing, plasmid elimination experiment, and real-time quantitative PCR. RESULTS For XH209, mean mutation rate of XH209-pMCR was 1.7 (95% confidence interval (CI) 0.76-2.54) × 10-8, while XH209 and XH209-pCR2.1 showed mutation rates of 2.0 (95% CI, 1.32-2.67) × 10-8 and 2.3 (95% CI 1.47-3.13) × 10-8. For KP10 and its derived strains KP10-pCR2.1, KP10-pMCR, the mutation rates were 3.5 (95% CI 0.77-6.13) × 10-8, 4.8 (95% CI 0.69-8.94) × 10-8 and 4.2 (95% CI 0.95-7.54) × 10-8 respectively. The mutation rates of E. coli strains Q3-pMCR and ATCC25922-pMCR were 3.4 (95% CI 0.19-7.47) × 10-8 and 1.54 (95% CI 0.27-2.8) × 10-9, which were significantly higher than their corresponding non-mcr-1-carrying strains (p < 0.05). CONCLUSIONS Beside the knowledge that mcr-1 mediates low-level colistin resistance, this gene also facilitates selection of HLCR mutants in E. coli, but does not affect K. pneumoniae.

Abstract
Abstract
Introduction: BRCA1 mutant cancers are defective for homologous recombination (HR) and as a result are highly sensitive to PARP inhibitor (PARPi) therapy. HR is initiated by DNA end resection, followed by the loading of RAD51 onto resected DNA. 53BP1 blocks DNA end resection and consequently prevents HR. In contrast, BRCA1 promotes DNA end resection, possibly by displacing 53BP1 from double-stranded DNA breaks. BRCA1 also contributes to HR downstream of DNA end resection by directly interacting with PALB2 and forming a larger BRCA1-PALB2-BRCA2-RAD51 complex that promotes RAD51 loading. In the absence of BRCA1, genetic disruption of 53BP1 has been shown to activate DNA end resection and restore HR, resulting in PARPi resistance. Despite clear evidence of activated DNA end resection, the efficiency of RAD51 loading and overall HR in the absence of BRCA1 and 53BP1 is unclear, and may be dependent on specific BRCA1 mutations that are present in a given cell line or mouse model.
Experimental Procedures: We investigated the impact of BRCA1 mutations on 53BP1-mediated restoration of HR and PARPi resistance. SUM149PT, UWB1.289, L56-BRC1 cell lines have BRCA1 exon 11 mutations and express the hypomorphic BRCA1-Δ11q splice variant; whereas MDA-MB-436, HCC1395 and SUM1315MO2 harbor RING or BRCT domain mutations and have undetectable truncated BRCA1 protein expression. We used CRISPR/Cas9 to generate a Brca11361fsX allele that was crossed with 53bp1-/- mice.
Results: 53BP1-targeting shRNA provided dramatic PARPi rescue in SUM149PT, UWB1.289, L56-BRC1 cells, with rucaparib IC50 values ranging from 100 to 500 nM. In contrast, 53BP1 shRNA scarcely impacted MDA-MB-436, HCC1395, and SUM1315MO2 cells, with IC50 values ranging from 0.5 to 2 nM. A closer inspection of HR steps revealed that 53BP1 loss activated DNA end resection in all cell lines, measured using RPA32 foci. However, downstream of resection, RAD51 foci increased in SUM149PT, UWB1.289, L56-BRC1 cells, but remained low in MDA-MB-436, HCC1395, and SUM1315MO2 cells. Because the former cell lines express the BRCA1-Δ11q splice variant that retains the ability to interact with PALB2, we examined the impact of hypomorphic BRCA1 protein expression and the BRCA1-PALB2 interaction on 53BP1-mediated PARPi rescue. Exogenous expression of BRCA1-Δ11q, BRCA1-ΔRING, or BRCA1-ΔBRCT all dramatically enhanced 53BP1-mediated RAD51 foci and PARPi resistance in an isogenic MDA-MB-436 complementation system. However, when a BRCA1L1407P missense mutation was introduced that abrogates the BRCA1-PALB2 interaction, 53BP1-induced RAD51 loading and PARPi resistance was completely abolished. The Brca11361fsX allele has a stop codon prior to critical amino acids required for Brca1-Palb2 association and homozygosity results in embryonic lethality. In contrast to previous studies using hypomorphic Brca1 alleles, matings with 53bp1-/- mice did not rescue the embryonic viability of Brca11361fsX mice.
Conclusions: These findings suggest that although 53BP1 loss of function is capable of promoting DNA end resection, efficient RAD51 loading remains dependent on BRCA1 and intact BRCA1-PALB2 complexes. Patients with BRCA1 mutations that prevent BRCA1-PALB2 association may have prolonged responses to PARPi therapy and are unlikely to succumb to 53BP1-loss of function-driven resistance.

Abstract
To explore the diagnostic value of copeptin (CPP) in cardiorenal syndrome (CRS) in rats and the association between CPP and impairment of heart and kidney, 60 male SD rats were randomly divided into blank control group (CK group), kidney failure group (SNX group), heart failure group (MI group), and CRS group. Heart and kidney function and their histology changes in rats from each group were detected. The correlation between serum CPP and heart and kidney function indexes was performed with Pearson correlation analysis. The HE staining of heart and kidney showed that the tissue lesion was more severe in CRS group than in SNX group and MI group. There was a significant positive correlation between serum CPP and brain natriuretic peptide (BNP) (r=0.638, P<0.05). No correlation was observed between serum CPP and cardiac function index (left ventricular systolic pressure, left ventricular diastolic pressure, left ventricular end-diastolic pressure) or renal function index (serum creatinine, urine creatinine, blood urea nitrogen) (r=0.512, 0.189,-0.063, 0.207, 0.290, 0.595, respectively, all P>0.05). The CPP level is associated with the degree of heart and kidney damage in CRS rats.
