Abstract
Objective: To explore the subjective and objective evaluation methods in functional rhinoplasty. Methods: Sixty-four patients who underwent rhinoplasty in the Department of Otorhinolaryngology, the First Affiliated Hospital of Chongqing Medical University were included in this study from January 2017 to October 2018. There were 32 males and 32 females, with the age ranging from 18 to 45 years old. Before and 6 months after operation, nasal ventilation function was evaluated by Visual Analogue Scale (VAS), Nasal Obstruction Symptom Evaluation (NOSE), nasal acoustic reflex and nasal resistance. Satisfaction with nasal appearance was evaluated by VAS, Rhinoplasty Outcome Evaluation (ROE) and facial proportions evaluation. Psychological state was assessed by Emotional Balance Scale and Rosenberg Self-esteem Scale. Finally, the Pearson correlation analysis of patient satisfaction was performed. SPSS 23.0 software was used for statistical analysis. Results: Compared with pre-operation, nasal obstruction VAS, NOSE scores, total nasal resistance and difference ratio of nasal resistance showed significantly decline after surgery (1.62±0.85 vs 7.56±1.44, 22.62±3.54 vs 69.75±7.85, (0.16±0.08) Pa·s/ml vs (0.31±0.43) Pa·s/ml, 0.33±0.28 vs 0.71±0.32, all P<0.05). VAS of appearance and ROE scores showed an increase after surgery (11.20±3.66 vs 2.70±0.97, 17.80±2.71 vs 7.50±1.12, all P<0.05). The measurement of the external nasal subunits showed that the length of the dorsum of the nose, the angle of the face to the nose, the angle of the frontal and the angle of the alar of the nose were obviously reduced ((29.33±4.26) mm vs (33.61±5.24) mm, (135.11±3.81)° vs (139.91±6.30)°, (130.63±2.88)° vs (136.74±5.72)°, (99.71±4.02)° vs (106.27±5.60)°, all P<0.05). The scores of postoperative Emotional Balance Scale and Rosenberg Self-esteem Scale increased significantly (5.88±1.54 vs 4.31±1.85, 28.31±2.64 vs 22.13±2.77, all P<0.05). The Pearson correlation analysis showed that patients' satisfaction was positively correlated with subjective score of nasal ventilation (VAS, NOSE), subjective score of nasal appearance (VAS, ROE) and emotional balance scale, while negatively correlated with nasal resistance, and not correlated with the measurement of external nasal subunit. There was a significant positive correlation between the subjective score of nasal ventilation and the measurement of nasal resistance, but there was no significant correlation between the subjective score of nasal appearance and the measurement of external nasal subunit. Conclusion: The subjective and objective evaluation of nasal ventilation function, aesthetics of nasal appearance and psychological state can evaluate the effect of functional rhinoplasty effectively.

Abstract
In conventional quasi-one-dimensional antiferromagnets with quantum spins, magnetic excitations are carried by either magnons or spinons in different energy regimes: they do not coexist independently, nor could they interact with each other. In this Letter, by combining inelastic neutron scattering, quantum Monte Carlo simulations, and random phase approximation calculations, we report the discovery and discuss the physics of the coexistence of magnons and spinons and their interactions in Botallackite-Cu_{2}(OH)_{3}Br. This is a unique quantum antiferromagnet consisting of alternating ferromagnetic and antiferromagnetic spin-1/2 chains with weak interchain couplings. Our study presents a new paradigm where one can study the interaction between two different types of magnetic quasiparticles: magnons and spinons.

Abstract
Purpose B7 homologue 6 (B7-H6) has been found at an up-regulated level in multiple cancer cells and identified to be positively correlated with inferior clinical features. In non-Hodgkin lymphoma (NHL), however, the roles of B7-H6 and the underlying mechanism of action remain unclear. Through in vivo and in vitro experiments, the aim of this study was to explore the regulatory mechanism of B7-H6 in NHL in order to provide new therapeutic strategies that can potentially be applied in clinical practice. Methods The expression of B7-H6 in T-lymphoblastic lymphoma (TLBL), diffuse large B cell lymphoma (DLBCL) and lymph node reactive hyperplasia (LRH) tissues were compared by immunohistochemistry. A total of 10 NHL cell lines were screened by Western blot to evaluate the expression of B7-H6. The effects of B7-H6 knockdown on cell proliferation, migration and invasion of NHL cells were studied in vivo using a transplanted tumor mice model, and in vitro by Cell Counting Kit-8 (CCK-8) and Transwell assays. Quantitative phosphoproteomics was performed to identify the changes of protein phosphorylation and related pathways affected by B7-H6. The effects of B7-H6 on NHL were validated via B7-H6 overexpression and pathway inhibitor assays. Results The expression levels of B7-H6 in NHL cell lines, and TLBL and DLBCL tissues were significantly increased compared with those in the control groups. Inhibition of cell proliferation, migration and invasion was observed in Jurkat and Raji cells with B7-H6 knockdown. The ability of B7-H6 in promoting tumorigenesis was further validated by in vivo experiments. In addition, Ras and HIF-1 signaling pathways were shown to be significantly affected by B7-H6 through quantitative phosphorylation proteomics analysis. Ras/MEK/ERK pathway was verified to be significantly inhibited after B7-H6 knockdown by Western blot analysis. Strikingly, MEK inhibitor AZD8330 was found to have the ability to sufficiently inhibit Ras/MEK/ERK pathway, partially reverse cell proliferation and completely reverse cell migration and invasion induced by B7-H6. Conclusion B7-H6 promotes cell proliferation, migration and invasion in NHL via Ras/MEK/ERK pathway. Hence, B7-H6 or Ras/MEK/ERK pathway targeting may be used as potential therapeutics for treating NHL.

Abstract
BACKGROUND ACOT plays an important role in lipid metabolism and recent studies found that ACOT participates in some kinds of tumorigenesis. However, both the role of ACOT and its significance have not been revealed in AML. Therefore, we conduct this study in order to investigate the association between AML and ACOT, and hopefully contributed to the management of AML. METHODS One hundred and fifty-six AML patients were enrolled in our study whose data were derived from the Cancer Genome Atlas database. There were 85 patients who received only chemotherapy and other 71 patients underwent allo-HSCT. RESULTS Patients in high ACOT7 group had a significant lower EFS and OS, while patients in high versus low expression levels of other types of ACOT showed no significant difference on the outcome. High level of ACOT7 related with poor outcome in both chemotherapy-only group and HSCT group. CONCLUSIONS High expression level of ACOT7 indicates unfavorable outcome in AML patients. Allo-HSCT could not overcome the unfavorable effect of ACOT7 in these patients.

Abstract
8033 Background: classical Hodgkin lymphoma (cHL) are characterized by genetic alterations at the 9p24·1 locus and PD-L1 ligand overexpression. GLS-010 is a novel fully human anti-PD-1 mAb and exhibited favorable result in previous Phase I study. This multi-center, single-arm Phase II clinical trial is aimed to further evaluate the safety and efficacy profile of GLS-010 in Chinese patients (pts) with relapsed or refractory cHL. Methods: All pts enrolled received GLS-010 240mg every 2 weeks until disease progression, death, unacceptable toxicity or withdraw from the study. The primary endpoint was objective response rate (ORR) by independent review committee (IRC) per Lugona 2014. Adverse events (AEs) were graded by NCI CTCAE v4.03. Results: 85 pts with relapsed or refractory cHL who had received at least 2 lines of prior systemic chemotherapies were enrolled and treated. As of August 2 2019, data cutoff, pts received a median of 8 treatment cycles (1 cycle include 2 injections), with 12 pts discontinued and 73 pts were still in treatment. At a median follow-up of 6.57 months, an ORR was reported in 78 of 85 patients (91.76%, 95%CI, 83.77-96.62), by an IRC assessment, including 30(35.3%) pts with a complete response (CR) and 48 pts (56.5%) with a partial response (PR). Median duration of response (DoR) and progression free survival (PFS) were not reached yet. Treatment-related adverse events (TRAEs) of any grade occurred in 77 (90.6%) of 85 patients, most of which were Grade 1-2.The most common TRAEs were fever (26/85, 30.6%), neutrophil count decreased (16/85, 18.82%), white blood cell count decreased (15/85, 17.65%). ≥ Grade 3 TRAEs occurred in 23 (27.06%) pts, most commonly, hepatic function abnormal (5/85, 5.88%), hyperuricaemia (4/85, 4.71%). Conclusions: GLS-010 showed impressive anti-tumor activity (ORR = 91.96%) and manageable safety profile in Chinese patients with relapsed or refractory cHL, which could be a new safe and effective treatment option in this setting. Clinical trial information: NCT03655483 .

The fair decision-making of children and adolescents with high-functioning autism spectrum disorder from the perspective of dual-process theories. BMC Psychiatry 2020; 20:152.

Abstract
BACKGROUND Fairness has received much attention in our society. At present, the findings regarding fair decision-making in high-functioning autism spectrum disorder (HF-ASD) are inconsistent. Previous studies have shown that the fair decision-making of typically developing children is influenced by theory of mind (ToM) and executive functioning (EF). As those with HF-ASD have defects in both domains, this study aims to explore the differences in fair decision-making between children and adolescents with HF-ASD and those with typical development (TD). METHODS We used a simple ultimatum game (UG) to explore 31 children and adolescents with HF-ASD and 38 children and adolescents with TD. T tests and chi-square tests were used to compare group differences, and Pearson correlation analysis and stepwise regression analysis were used to analyse the mechanisms influencing the two groups' unfair acceptance rates. RESULTS The results show that children with HF-ASD are more likely to accept unfair offers, but for adolescents, the difference is not significant. Regression analysis showed that the interaction between the behavior regulation index (BRI) and age could negatively predict the unfair acceptance rate of children and adolescents with HF-ASD. Working memory and ToM can negatively predict the unfair acceptance rate of those with TD. CONCLUSION This study concluded that the development of fair decision-making by children and adolescents with HF-ASD falls far behind that of those with TD. Intuition processes play a dominant role in the fair decision-making processes of children and adolescents with HF-ASD, and we believe that comorbidity, age, experience and emotional management are important factors influencing the fair decision-making of individuals with HF-ASD.

Abstract
G protein-coupled receptors (GPCRs) are one of the most important drug targets, accounting for ∼34% of drugs on the market. For drug discovery, accurate modeling and explanation of bioactivities of ligands is critical for the screening and optimization of hit compounds. Homologous GPCRs are more likely to interact with chemically similar ligands, and they tend to share common binding modes with ligand molecules. The inclusion of homologous GPCRs in learning bioactivities of ligands potentially enhances the accuracy and interpretability of models due to utilizing increased training sample size and the existence of common ligand substructures that control bioactivities. Accurate modeling and interpretation of bioactivities of ligands by combining homologous GPCRs can be formulated as multitask learning with joint feature learning problem and naturally matched with the group lasso learning algorithm. Thus, we proposed a multitask regression learning with group lasso (MTR-GL) implemented by l2,1-norm regularization to model bioactivities of ligand molecules and then tested the algorithm on a series of thirty-five representative GPCRs datasets that cover nine subfamilies of human GPCRs. The results show that MTR-GL is overall superior to single-task learning methods and classic multitask learning with joint feature learning methods. Moreover, MTR-GL achieves better performance than state-of-the-art deep multitask learning based methods of predicting ligand bioactivities on most datasets (31/35), where MTR-GL obtained an average improvement of 38% on correlation coefficient (r2) and 29% on root-mean-square error over the DeepNeuralNet-QSAR predictors.

Abstract
Acute myeloid leukemia (AML) is a hematological malignancy characterized by the proliferation of immature myeloid cells, with impaired differentiation and maturation. Pyruvate dehydrogenase kinase (PDK) is a pyruvate dehydrogenase complex (PDC) phosphatase inhibitor that enhances cell glycolysis and facilitates tumor cell proliferation. Inhibition of its activity can induce apoptosis of tumor cells. Currently, little is known about the role of PDKs in AML. Therefore, we screened The Cancer Genome Atlas (TCGA) database for de novo AML patients with complete clinical information and PDK family expression data, and 84 patients were included for the study. These patients did not undergo allogeneic hematopoietic stem cell transplantation (allo-HSCT). Univariate analysis showed that high expression of PDK2 was associated with shorter EFS (P = 0.047), and high expression of PDK3 was associated with shorter OS (P = 0.026). In multivariate analysis, high expression of PDK3 was an independent risk factor for EFS and OS (P < 0.05). In another TCGA cohort of AML patients who underwent allo-HSCT (n = 71), PDK expression was not associated with OS (all P > 0.05). Our results indicated that high expressions of PDK2 and PDK3, especially the latter, were poor prognostic factors of AML, and the effect could be overcome by allo-HSCT.

Abstract
OBJECTIVE To carry out multipath cytogenetic analysis of a rare case of acute myeloid leukemia (AML) with 11q23 aberration and D13S319 deletion. METHODS G+R banding technique was used to analyze the chromosomal karyotype of the patient after 24 h of cell culture. Combined interphase and metaphase fluorescence in situ hybridization (FISH) was used to detect specific chromosomal sites for complex translocations and minor missing fragments. RESULTS The patient was found to harbor MLL-AF10 fusion gene due to rearrangement of the mixed lineage leukemia (MLL) gene in conjunct with deletion of the D13S319 locus on chromosome 13. CONCLUSION Whether MLL gene rearrangement and absence of D13S319 locus has a double impact on AML should attract more attention. For AML patient with clonal abnormalities such as 13q-, del(13)(q14), -13 or der(13), FISH assay should be proof and considered to determine the size of missing fragment so as targeted therapy may be implemented.

Abstract
Background: Although autism spectrum disorder (ASD) can currently be diagnosed at the age of 2 years, age at ASD diagnosis is still 40 months or even later. In order to early screening for ASD with more objective method, behavioral videos were used in a number of studies in recent years. Method: The still-face paradigm (SFP) was adopted to measure the frequency and duration of non-social smiling, protest behavior, eye contact, social smiling, and active social engagement in high-risk ASD group (HR) and typical development group (TD) (HR: n = 45; TD: n = 43). The HR group was follow-up until they were 2 years old to confirm final diagnosis. Machine learning methods were used to establish models for early screening of ASD. Results: During the face-to-face interaction (FF) episode of the SFP, there were statistically significant differences in the duration and frequency of eye contact, social smiling, and active social engagement between the two groups. During the still-face (SF) episode, there were statistically significant differences in the duration and frequency of eye contact and active social engagement between the two groups. The 45 children in the HR group were reclassified into two groups after follow-up: five children in the N-ASD group who were not meet the criterion of ASD and 40 children in the ASD group. The results showed that the accuracy of Support Vector Machine (SVM) classification was 83.35% for the SF episode. Conclusion: The use of the social behavior indicator of the SFP for a child with HR before 2 years old can effectively predict the clinical diagnosis of the child at the age of 2 years. The screening model constructed using SVM based on the SF episode of the SFP was the best. This also proves that the SFP has certain value in high-risk autism spectrum disorder screening. In addition, because of its convenient, it can provide a self-screening mode for use at home. Trial registration: Chinese Clinical Trial Registry, ChiCTR-OPC-17011995.

Abstract
Objective: To investigate the aberrant eating behaviors (EBs), gastrointestinal (GI) symptoms, and food intolerance in children with autism spectrum disorder (ASD) and their association with clinical core symptoms of ASD. Method: A total of 94 preschool children with ASD treated at the Child Mental Health Research Center of Nanjing Brain Hospital between October 2016 and April 2018 were enrolled. In addition, 90 children with typical development (TD) in the community during the same period were recruited. The conditions of aberrant EBs and GI symptoms in children were investigated using questionnaire surveys. Serum specific IgG antibodies against 14 kinds of food were detected using enzyme-linked immunosorbent assays (ELISAs). Results: The detection rate of aberrant EBs in the ASD group was significantly higher than that in the TD group (67.39 vs. 34.94%), and the rate of GI symptoms was also higher in the ASD group than that in the TD group (80.22 vs. 42.11%). Detection of food intolerance in children with ASD showed that the positive rate was 89.89% and that the majority of children had multiple food intolerances. The correlation analysis results showed that the severity of aberrant EBs positively correlated with stereotyped behavior of children with ASD (r = 0.21, P = 0.04) and that food-specific IgG antibodies concentrations positively correlated with high-level stereotyped behavior in children with ASD (r = 0.23, P = 0.03). Conclusion: ASD with aberrant EBs or high food-specific IgG antibodies concentrations had more severe stereotyped behavior, which may have implications for exploring the immune mechanism of ASD.

Abstract
The number of children and adolescents with mental disorders in China is increasing year by year, but the child and adolescent psychiatrists (CAPs) remain very scarce. So far, there is only a national psychiatrist certification system, and no child and adolescent psychiatrist certification system. Instead, the psychiatrist can receive the post-graduation training certificate or nationally approved Ph.D. and Master's degree training certificate for becoming a CAP. Currently, studies on the training status of CAPs in China are unavailable. This study investigated the current training status of CAPs in China intending to improve the relevant training programs. Self-developed questionnaires were distributed to 28 Executive Committee members of Chinese Society of Child and Adolescent Psychiatry from 32 training hospitals which Nationally approved Ph.D. and Master's degree training base for child and adolescent psychiatry or post-graduation training (Intern and Fellow) base for child and adolescent psychiatry in 14 provinces and municipalities for collecting necessary information of the respondents, and evaluation of current education and training. Using the descriptive analysis for statistical analysis to understand the current training status of child psychiatrists in China. A total of 28 valid questionnaires were returned. The training units were concentrated in large- and medium-sized cities. Moreover, the current medical personnel in China for diagnosing and treatment of children and adolescents with mental disorders was small in number with fixed learning modes. For the training of CAPs, the scientific basis of the training content, as well as the practicality of the training content, and the ability to solve problems, are not sufficient. Furthermore, the effects of current educational training of CAPs regarding teaching and professional, scientific research abilities remained relatively weak. Therefore, it is necessary to focus on training comprehensive qualities and abilities, such as the spirit of dedication. Currently, physicians who have received post-graduate training or Ph.D. and Master's degree training in child and adolescent psychiatry in China are very scarce. Although CAPs have a long history of training, post-graduate, or doctoral master's degree training is mainly a training method. And, the national specialized certification system for CAPs pilot in major cities. The training system of CAPs should be further improved in the future, and the number of CAPs should be increased.

Predictors of Change in Play-Based Communication and Behavior Intervention for High-Risk ASD: The Role of Mother-Child Dyadic Synchrony. Front Pediatr 2020; 8:581893. [PMID: 33344381 PMCID: PMC7738436 DOI: 10.3389/fped.2020.581893] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/10/2020] [Accepted: 11/09/2020] [Indexed: 11/30/2022] Open
Abstract
Background: Interindividual variability is important in the evolution of adaptative profiles of children with ASD having benefited from an early intervention make up for deficits in communication, language and social interactions. Therefore, this paper aimed to determine the nature of factors influencing the efficacy variability of a particular intervention technique i.e., "Play-based communication and behavior intervention" (PCBI). Methods: The participants comprised 70 13-30-month-old toddlers with ASD enrolled in PCBI for 12 weeks. The Autism Treatment Evaluation Checklist (ATEC) was used to evaluate the efficacy of PCBI. Video recordings of 5 min of free-play before and after PCBI were used to examine behaviors of mothers and children and parent-child dyadic synchrony. Hierarchical multiple regression analyses and machine learning algorithms were performed to explore the effect of these potential predictors (mothers' factors, children's factors and videotaped mother-child interaction) of intervention efficacy. Results: The hierarchical regression analysis and the machine learning algorithms indicated that parenting stress, level of completion of training at home and mother-child dyadic synchrony were crucial factors in predicting and monitoring the efficacy of PCBI. Conclusions: In summary, the findings suggest that PCBI could be particularly beneficial to children with ASD who show a good performance in the mother-child dyadic synchrony evaluation. A better dyadic mother-child synchrony could enhance the PCBI efficacy through adapted emotional and behavioral responses of the mother and the child and has a beneficial influence on the child's psychological development.

Abstract
BACKGROUND Individuals with autism spectrum disorder (ASD) have social interaction deficits and difficulties in emotional regulation. The neural substrates for these socio-affective deficits are not yet clear, but one potential candidate is maldevelopment of the uncinate fasciculus (UF), a white matter tract thought to be involved in socio-affective processing. However, the developmental trajectory of the UF in young children with social interaction deficits has not been examined. The present study was designed to describe the developmental growth trajectory of the UF and the relationships between UF development and social deficits in ASD. METHODS Eigenvalues of the UF were measured by diffusion tensor imaging (DTI)-based tractography in 37 children with ASD and 27 matched 2-3-year-old subjects with developmental delay (DD) at baseline (time 1) and at 2-year follow-up (time 2). Growth rates of the UF were compared between groups and associations with social deficit scores according to the Autism Diagnostic Interview-Revised (ADI-R) analyzed by Pearson's correlations. RESULTS At time 1, axial diffusivity (AD) of the left UF was significantly larger in the ASD group than the DD group. At time 2, left UF fractional anisotropy (FA) was significantly higher and radial diffusivity (RD) significantly lower in the ASD group than the DD group. The rate of UF growth during this 2-year interval was faster in children with ASD than DD. Significant negative correlations were found between the rise in ADI-R social deficit measures and both right UF RD and left UF mean diffusivity (MD). CONCLUSIONS Young children with ASD demonstrate UF overgrowth during the 2-year development period between 2 and 3 and 4-5 years of age, and this white matter abnormality is directly associated with the progression of social deficits.

Abstract
With the stringent emission regulation taking effect, it is difficult for the conventional desulfurization technology in circulating fluidized bed (CFB) boilers to meet the requirements of ultralow SO2 emission. Therefore, in this paper, the application of natural ultrafine limestone, with a Sauter mean diameter of less than 20 μm, was tested by conducting bench-scale, pilot-scale, and commercial-scale experiments to realize highly efficient desulfurization in CFB furnaces. In the past, such small-size limestone was considered unsuitable for CFB boilers. However, as demonstrated by bench-scale results, the desulfurization performance was clearly superior to that of coarse limestone, especially at low SO2 concentrations. In a 3 MWth pilot-scale CFB boiler, the ultrafine limestone exhibited competent desulfurization efficiency to that of the coarse limestone but clearly less significant catalytic effects on NOx formation. As revealed by field tests in four commercial-scale CFB boilers, when high-efficiency cyclones were applied to CFB boilers, the mass inventory of ultrafine particles was significantly increased and the residence time would be extended accordingly; thus, the ultrafine limestone can be used to achieve high desulfurization efficiency and even ultralow SO2 emission with a favorable Ca/S ratio. Furthermore, a technical roadmap was drawn for the cost-effective control of SO2 emission.

Abstract
N6-methyladenosine (m6A) is the most abundant eukaryote mRNA modification, modulated by regulators known as epigenetic writers, erasers and readers, which are known to serve crucial roles in mRNA metabolism. However, the role of m6A during B-cell development and B-cell tumorigenesis remains poorly understood. By analyzing the gene expression profile of 123 mantle cell lymphoma cases from the Gene Expression Omnibus database, the present study demonstrated that one-half of the m6A regulators were able to predict patient survival in mantle cell lymphoma, notably the m6A.index. The expression levels of the m6A regulators were regarded as good classifiers in mantle cell lymphoma. The m6A.index-low mantle cell lymphoma type exhibited a poor patient survival and lower mRNA levels from the total transcriptome. The m6A regulators may be associated with the cell division and the RNA metabolic pathways, which may result in poor survival of patients with mantle cell lymphoma.

Abstract
BACKGROUND Endothelial dysfunction plays a key role in diabetic atherosclerosis. High glucose (HG) is considered a stimulator in the development of diabetic atherosclerosis. The endoplasmic reticulum (ER) stress response is involved in HG-induced vascular injury. Crocin has antioxidative and antiapoptotic properties. OBJECTIVE The current study was to evaluate whether crocin can protect human umbilical vein endothelial cells (HUVECs) from HG-induced injury and explored the associated mechanism. METHODS HUVECs were treated with 33 mmol/L glucose as the HG condition. The endothelial protective effects of crocin were evaluated by comparison with the control groups. RESULTS The exposure of HUVECs to HG for 24 h remarkably induced the ER stress response and a sequence of injuries, as demonstrated an increase in the apoptotic cell number, the reactive oxygen species level and inflammatory cytokine generation, as well as a decline in vascular endothelial growth factor A expression. These changes were markedly alleviated by pretreating the HUVECs with either crocin or 4-phenylbutyrate (ER stress inhibitor) before exposure to HG. CONCLUSION Crocin exerted antioxidative, antiapoptotic, anti-inflammatory and proangiogenic effects in the HG-induced HUVEC injury model, which were probably mediated by a favorable modification of ER stress that requires further investigation.

Abstract
Motivation Precise assessment of ligand bioactivities (including IC50, EC50, Ki, Kd, etc.) is essential for virtual screening and lead compound identification. However, not all ligands have experimentally determined activities. In particular, many G protein-coupled receptors (GPCRs), which are the largest integral membrane protein family and represent targets of nearly 40% drugs on the market, lack published experimental data about ligand interactions. Computational methods with the ability to accurately predict the bioactivity of ligands can help efficiently address this problem. Results We proposed a new method, WDL-RF, using weighted deep learning and random forest, to model the bioactivity of GPCR-associated ligand molecules. The pipeline of our algorithm consists of two consecutive stages: (i) molecular fingerprint generation through a new weighted deep learning method, and (ii) bioactivity calculations with a random forest model; where one uniqueness of the approach is that the model allows end-to-end learning of prediction pipelines with input ligands being of arbitrary size. The method was tested on a set of twenty-six non-redundant GPCRs that have a high number of active ligands, each with 200-4000 ligand associations. The results from our benchmark show that WDL-RF can generate bioactivity predictions with an average root-mean square error 1.33 and correlation coefficient (r2) 0.80 compared to the experimental measurements, which are significantly more accurate than the control predictors with different molecular fingerprints and descriptors. In particular, data-driven molecular fingerprint features, as extracted from the weighted deep learning models, can help solve deficiencies stemming from the use of traditional hand-crafted features and significantly increase the efficiency of short molecular fingerprints in virtual screening.

Abstract
To clarify the role of red blood cell (RBC) lifespan in anemia of multiple myeloma (MM), RBC lifespan was detected in 40 newly diagnosed MM patients by measuring exhaled endogenous carbon monoxide concentration. Mean RBC lifespan was significantly reduced in MM patients (63 ± 23 d) than healthy controls (116 ± 17 d). RBC lifespan in MM patients without anemia (78 ± 21 d) was also significantly lower than for healthy controls. RBC lifespan in MM patients with anemia (52 ± 18 d) was significantly lower than those without. Besides, RBC lifespan in MM patients with renal insufficiency (50 ± 16 d) was lower than those without (66 ± 23 d). RBC lifespan was significantly negatively correlated with % reticulocytes, erythropoietin concentration, % clonal plasma cells, β2-microglobulin (MG) level, and creatinine level. Receiver operator characteristics curve was used to determine a cut-off point (61 d) to predict effect of RBC lifespan on chemotherapy. Overall response rates were significantly higher in MM patients with RBC lifespan ≥61 d than those <61 d. In conclusion, RBC lifespan of MM patients is reduced, and severely shortened RBC lifespan may be involved in the occurrence of anemia in MM patients. The chemotherapeutic effect of MM patients can be predicted by RBC lifespan.

Abstract
MOTIVATION Accurate prediction and interpretation of ligand bioactivities are essential for virtual screening and drug discovery. Unfortunately, many important drug targets lack experimental data about the ligand bioactivities; this is particularly true for G protein-coupled receptors (GPCRs), which account for the targets of about a third of drugs currently on the market. Computational approaches with the potential of precise assessment of ligand bioactivities and determination of key substructural features which determine ligand bioactivities are needed to address this issue. RESULTS A new method, SED, was proposed to predict ligand bioactivities and to recognize key substructures associated with GPCRs through the coupling of screening for Lasso of long extended-connectivity fingerprints (ECFPs) with deep neural network training. The SED pipeline contains three successive steps: (i) representation of long ECFPs for ligand molecules, (ii) feature selection by screening for Lasso of ECFPs and (iii) bioactivity prediction through a deep neural network regression model. The method was examined on a set of 16 representative GPCRs that cover most subfamilies of human GPCRs, where each has 300-5000 ligand associations. The results show that SED achieves excellent performance in modelling ligand bioactivities, especially for those in the GPCR datasets without sufficient ligand associations, where SED improved the baseline predictors by 12% in correlation coefficient (r2) and 19% in root mean square error. Detail data analyses suggest that the major advantage of SED lies on its ability to detect substructures from long ECFPs which significantly improves the predictive performance. AVAILABILITY AND IMPLEMENTATION The source code and datasets of SED are freely available at https://zhanglab.ccmb.med.umich.edu/SED/.

Abstract
Background: Actinins are major cytoskeletal proteins that mediate sarcomere function, and they also have important non-muscle functions such as regulating cytokinesis, cell adhesion and migration. There are four isoforms of actinins in mammals (ACTN1-4). Recently, the relationship between actinins and cancer has been discovered in many types of malignancy, yet their prognostic significance in acute myeloid leukemia (AML) remains unclear. Methods: We collected data of 155 de novo AML patients from The Cancer Genome Atlas (TCGA) database; 85 patients received chemotherapy only and 70 patients underwent allogeneic hematopoietic stem cell transplantation (allo-HSCT). We divided each treatment groups into sub-groups based on the median expression levels of ACTN1-4. Results: Survival analysis showed that in the chemotherapy-only group, high ACTN1 and ACTN3 expression were associated with shorter event-free survival (EFS) and overall survival (OS) (p<0.01). Multivariate analysis suggested that high expression of ACTN1 and ACTN3 (p<0.05) were independent poor prognostic factors. In the allo-HSCT group, ACTN1-4 expression had no impact on survival. Conclusions: Our study suggested that high expression levels of ACTN1 and ACTN3 adversely affected the survival of AML patients, but their harmful impact could be overcome by allo-HSCT.
