Abstract
The desired color is a key indicator for consumer acceptability of Chinese sugar-smoked chicken. To investigate the formation of color attributes of Chinese sugar-smoked chicken during processing, color values, structural characteristics, and components of brown pigment were evaluated in 2 groups, which were defined as brown skin (BS) and normal skin (NS) of Chinese sugar-smoked chicken based on their color values. Compared with the NS samples, the BS samples showed significantly lower values of lightness, redness, and yellowness and higher content of malondialdehyde and 5-hydroxymethylfurfural. UV-visible and Fourier-transform infrared spectra suggested that the structure of brown pigment was similar to melanin. The brown pigment consisted of multiple chemical components including the polymer of fructose and glucose, and derivatives produced by lipid oxidation, which were identified by HPLC-tandem mass spectrometry. The polymer content of glucose and fructose, which was demonstrated as sucrose by HPLC analysis, was higher in the BS group than in the NS group. Our results indicated that the higher content of the polymer of glucose and fructose was mainly responsible for the brown color of Chinese sugar-smoked chicken.

Abstract
INTRODUCTION The Clinical and Translational Science Awards (CTSA) Consortium, a network of academic health care institutions with CTSA hubs, is charged with improving the national clinical and translational research enterprise. The CTSA Consortium and the NIH National Center for Advancing Translational Sciences implemented the Common Metrics Initiative comprised of standardized metrics and a shared performance improvement framework. This article summarizes hubs' perspectives on its value during the initial implementation. METHODS The value was assessed across 58 hubs. Survey items assessed change in perceived ability to manage performance and advance clinical and translational science. Semi-structured interviews elicited hubs' perspectives on meaningfulness and value-added of the Common Metrics Initiative and hubs' recommendations. RESULTS Hubs considered their abilities to manage performance to have improved, but there was no change in perceived ability to advance clinical and translational science. The initiative added value by providing a formal structured process, enabling strategic conversations, facilitating improvements in processes, providing an external impetus for improvement, and providing justification for funds invested. Hubs were concerned about the usefulness of the metrics chosen and whether the value-added was sufficient relative to the effort required. Hubs recommended useful benchmarking, disseminating best practices and promoting peer-to-peer learning, and expanding the use of data to inform the initiative. CONCLUSIONS Implementing Common Metrics and a performance improvement framework yielded concrete short-term benefits, but concerns about usefulness remained, particularly considering the effort required. The Common Metrics Initiative should focus on facilitating cross-hub collaboration around metrics that address high-priority impact areas for individual hubs and the Consortium.

Abstract
BACKGROUND To prevent the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), strict control of person-to-person transmission is essential. Family transmission is the most common route of transmission; however, family transmission patterns and outcomes are not well understood. METHODS We enrolled confirmed cases discharged from Wuhan Zhuankou Fangcang Shelter Hospital from February 17, 2020 to March 8, 2020 along with the family members they had contact with, to evaluate baseline characteristics, family transmission patterns and outcomes. The follow-up period lasted until May 8, 2020. RESULTS This study evaluated 369 participants, which included 100 patients admitted to the shelter hospital and the family members they had contact with. Family transmission occurred in 62% of household, with 190 cases confirmed to have SARS-CoV-2 infection. There were eight patterns of family transmission, and spousal transmission (44/83, 53.0%) was the most common pattern, especially in the middle-age generation group (35/83, 42.2%). The homes of the families in which all members were infected had a smaller per capita area than those of other families (29.1 ± 11.89 cm2 vs 41.0 ± 19.70 cm2, respectively, P = 0.037), and the per capita area was negatively associated with the number of infected family members (R = -0.097, P = 0.048). Of the 190 confirmed cases, the 113 mild or moderate cases were monitored in fangcang (including Wuhan Zhuankou Fangcang and other fangcang), and the 59 severe cases were treated at designated hospitals. By the end of follow-up, 185 patients recovered and returned home after completing at least 14 days of isolation at the community quarantine center, four died in hospitals, and one died at home before hospitalization. Interestingly, four patients had positive nucleic acid test results after previous negative results, though none of these patients were re-hospitalized, and none of their close contacts reported an infection. CONCLUSIONS Our data found eight family transmission patterns, of which spousal transmission was the most common. Some patients were also found to have positive test results during follow-up.

Abstract
The mechanisms of drug resistance in multiple myeloma are poorly understood. Here we show that CD47, an integrin-associated receptor, is significantly upregulated in drug resistant myeloma cells in comparison with parental cells, and that high expression of CD47 detected by immunohistochemistry is associated with shorter progression free and overall survivals in multiple myeloma patients. We show that miR-155 is expressed at low levels in drug resistant myeloma cells and is a direct regulator of CD47 through its 3'UTR. Furthermore, low miR-155 levels are associated with advanced stages of disease. MiR-155 overexpression suppressed CD47 expression on myeloma cell surface, leading to induction of phagocytosis of myeloma cells by macrophages and inhibition of tumor growth. MiR-155 overexpression also re-sensitized drug-resistant myeloma cells to bortezomib leading to cell death through targeting TNFAIP8, a negative mediator of apoptosis in vitro and in vivo. Thus, miR-155 mimics may serve as a promising new therapeutic modality by promoting phagocytosis and inducing apoptosis in patients with refractory/relapsed multiple myeloma.

Abstract
We developed a type of toroidal multi-pass cell with multi-layer patterns based on the off-axis model. The effective path length of the original toroidal multi-pass cell is extended several roundtrips in comparison with the single-layer pattern, since the inner surface of the toroidal multi-pass cell is more efficiently utilized. The light pattern has been achieved by using the simple ring surface, which is easy to fabricate. The exact analytical equations for the design of the toroidal multi-pass cell were derived based on analytical vector calculations. A series of numerical ray tracing simulations is presented, and the maximum theoretical optical path length that can be reached is 30 m with a setup of 5 cm column radius. Furthermore, two practical spot patterns are demonstrated with a path length of 8.3 m for a two-layer pattern and 10 m for a three-layer pattern, with respective effective volumes of 63 mL and 94 mL. Furthermore, the fringe effect is substantially reduced to less than 0.5% by the usage of our designed mask.

Abstract
The aim of this study was to investigate the effect of low-dose ruxolitinib (daily dose ≤ 10 mg) for the treatment of myelofibrosis (MF). A retrospective analysis was performed on a total of 88 patients with myeloproliferative neoplasm-associated MF (MPN-MF) who were diagnosed and treated in West China Hospital, Sichuan University, China. A total of 44 MPN-MF patients received a low dose of ruxolitinib (daily dose ≤ 10 mg), while another 44 patients received 10-25 mg twice daily. Low-dose ruxolitinib treatment resulted in slow, but gradual spleen response. Compared with baseline, the mean changes in palpable spleen length in the low- and high-dose groups were -26.9 and -49.0% after 12 weeks of treatment, respectively, and -46.7 and -64.1% after 48 weeks of treatment, respectively. In the low dose group, the median myeloproliferative neoplasm symptom assessment form (MPN-SAF) total symptom score (TSS) decreased by 37.8 and 35.9% at the 12 weeks and 48 weeks after treatment, respectively. No statistical difference was observed in MPN-SAF TSS among different dose groups. After 48 weeks of treatment, bone marrow (BM) fibrosis improved in 43.3% (13/30) of evaluated patients and was stable in 56.7% (17/30) patients. In the low-dose treated group, BM fibrosis improved in 50% patients and was stable in remaining 50%. Low-dose ruxolitinib is effective in treating MF.

Abstract
As a class of alternative flame retardants, "novel" brominated flame retardants (NBFRs) have been widely used in clothing, textiles, electronics, building materials, and plastics and are frequently found in environmental samples. Although the use and discharge of NBFRs are increasing all over the world, little information is available about their fates and removal in wastewater treatment plants (WWTPs). This study investigated the occurrence and behavior of 2,4,6-tribromophenyl allyl ether (ATE), 2,3-dibromopropyl tribromophenyl ether (DPTE), tetrabromo-o-chlorotoluene (TBCT), pentabromobenzyl acrylate (PBBA), 1,2-bis(2,4,6-tribromophenoxy) ethane (BTBPE), bis(2-ethylhexyl)-3,4,5,6-tetrabromo-phthalate (TBPH), and decabromodiphenyl ethane (DBDPE) in a municipal WWTP in Beijing, China. Four of the NBFRs (ATE, BTBPE, TBPH, and DBDPE) were detected in all wastewater and biosolid samples. The dominant compound in both wastewater and biosolid samples was DBDPE, with concentrations in the ranges of 6.4-18 ng/L and 83-288 ng/g dry weight (dw), respectively. A mass flow analysis indicated that the overall removal efficiencies were 31±18% for ATE, 97±1.5% for DPTE, 79±11% for BTBPE, 87±5.3% for TBPH, and 93±3.3% for DBDPE, but the removal efficiency in aqueous phase only ranged from -43 (ATE) to 57% (DBDPE). The low and negative removal efficiencies of ATE were possibly due to the transformation of DPTE during the anaerobic treatment processes. Under the aerobic conditions, BTBPE, TBPH and DBDPE underwent a very slow biodegradation. A total of 68-91% of the initial mass loadings of ATE, BTBPE, TBPH and DBDPE were found in the biosolid samples, suggesting that the four NBFRs were removed mainly via sorption in the WWTP.The biosolid was a huge reservoir of target NBFRs, and effective removal of NBFRs during treatment in the WWTP is critical.

Abstract
Sugar-smoking contributes to improving flavor attributes of meat products. However, there is rather limited information concerning the relationship between sugar-smoking process parameters and volatile compound (VC) fingerprinting as well as related quality attributes of sugar-smoked chicken. In this work, the changes in VC across the whole sugar-smoking process were determined and analyzed and physicochemical properties, free fatty acid, thiobarbituric acid reactive substances values, and E-nose were also performed to characterize the quality properties of sugar-smoked chicken breast (CB) and chicken skin (CS). Results suggested that a higher amount (P < 0.05) of total VC was observed in CS compared with CB during the whole processing, which may be correlated with higher thiobarbituric acid reactive substances values, and higher polyunsaturated fatty acid/saturated fatty acid ratio. According to E-nose analysis, the volatile flavor is clearly separated in the sugar-smoking stage. Volatile fingerprinting results revealed that heterocycles were the characteristic flavor formed during sugar-smoking process and hexanal, nonanal, furfural, 5-methyl-2-furancarboxaldehyde, and 2-acetyl-5-methylfuran were the major volatiles of the CS, which was closely related to lipid oxidation and caramelization reaction. Above all, the flavor of sugar-smoked chicken was mainly derived from CS and sugar-smoked process improved the flavor of CS. This study could provide theoretical guidance for regulation of the color and flavor of sugar-smoked chicken and further promote the development of the industry.

Abstract
INTRODUCTION Examination of a blood film is the second most common hematology test, after the complete blood count. Interpretation of a peripheral blood film by trained laboratory professionals provides valuable diagnostic information. The Institute for Quality Management in Healthcare (IQMH) Hematology Scientific Committee developed a questionnaire to gather information regarding current practices for manual blood film review and reporting from laboratories participating in IQMH Morphology proficiency testing (PT) surveys. METHODS An online survey was distributed to 174 laboratories, 97% submitted results. RESULTS Of the respondents, the majority (82%) indicated affiliation with small- or medium-sized hospitals (<500 beds). 80% of respondents had core laboratory technologists performing manual blood film reviews, while only 2% utilized dedicated hematology technologists with morphology expertise. All respondents had a policy for manual blood film review by a technologist, 70% did not have blood films reviewed by a senior/charge technologist prior to review by a physician. The majority (88%) of participants included morphological findings in their critical result list; of these, 98% include malaria and 88% include the first-time finding of blasts as critical results. 59% of participants indicated that they have a procedure in place to ensure that interpretation and confirmation of first-time potentially significant morphological findings are available from a physician at all times. CONCLUSION This survey identified significant variation in blood film review and reporting practices across participating laboratories. The IQMH Hematology Scientific Committee will develop best practice recommendations to guide and standardize practice.

Abstract
In the existing works of person re-identification (ReID), batch hard triplet loss has achieved great success. However, it only cares about the hardest samples within the batch. For any probe, there are massive mismatched samples (crucial samples) outside the batch which are closer than the matched samples. To reduce the disruptive influence of crucial samples, we propose a novel isosceles contraint for triplet. Theoretically, we show that if a matched pair has equal distance to any one of mismatched sample, the matched pair should be infinitely close. Motivated by this, the isosceles constraint is designed for the two mismatched pairs of each triplet, to restrict some matched pairs with equal distance to different mismatched samples. Meanwhile, to ensure that the distance of mismatched pairs are larger than the matched pairs, margin constraints are necessary. Minimizing the isosceles and margin constraints with respect to the feature extraction network makes the matched pairs closer and the mismatched pairs farther away than the matched ones. By this way, crucial samples are effectively reduced and the performance on ReID is improved greatly. Likewise, our isosceles contraint can be applied to quadruplet as well. Comprehensive experimental evaluations on Market-1501, DukeMTMC-reID and CUHK03 datasets demonstrate the advantages of our isosceles constraint over the related state-of-the-art approaches.

Abstract
OBJECTIVE To describe caregiving work outcomes and related indirect (ie, productivity) and direct (ie, caregiving hours and expenses) costs. METHODS A national, population-based survey to identify employed caregivers assisting a person with treatment-resistant depression (TRD) and a comparison group of employed caregivers assisting others (No TRD). RESULTS Screening identified 169 TRD caregivers and 1070 No TRD caregivers providing 23.3 and 14.6 mean weekly caregiving hours, respectively. Adjusted annual indirect cost estimates were $11,121 for caregivers of TRD and $7761 for caregivers in the No TRD group (P ≤ 0.0001). At-work productivity loss (presenteeism) was the largest component. Adjusted annual direct cost estimates were $29,805 for caregivers of TRD and $20,642 for caregivers in the No TRD group (P ≤ 0.0001). CONCLUSIONS TRD exacts a toll on caregivers and their employers exceeding that for other caregivers.

Abstract
UNLABELLED Stem cells are considered to be one of the greatest potential treatments to cure degenerative diseases. Stem cells injection for knee osteoarthritis (OA) is still a relatively new treatment and has not yet gained popularity. So, the effectiveness, safety and potential of mesenchymal stem cells (MSCs) for knee OA treatment is worthy to be explored. Explore the effectiveness and safety of mesenchymal stem cells (MSCs) in the treatment of knee osteoarthritis. We collected clinical trials using MSCs as treatment for knee OA (before April 2019), including randomized controlled trials (RCTs), retrospective studies and cohort studies. We searched PubMed, EMBASE, Cochrane Library, Web of Science and the ClinicalTrials.gov with keywords (Mesenchymal stem cells [MSCs], Knee osteoarthritis, Effectiveness and Safety), and then performed a systematic review and cumulative metaanalysis of all RCTs and retrospective comparative studies. To evaluate the effectiveness and safety of MSC in knee OA treatment, we applied visual analog scale score, Western Ontario and McMaster Universities Osteo-arthritis Index and adverse events. We included 15 RCTs, two retrospective studies and two cohort studies including a total of 584 knee OA patients in this study. We demonstrated that MSC treatment could significantly decrease visual analog scale in a 12-month follow-up study compared with controls (p < 0.001). MSC therapy also showed significant decreases in Western Ontario and McMaster Universities Osteoarthritis Index scores after the 6-month follow-up (p < 0.001). MSC therapy showed no difference compared with controls (p > 0.05) in adverse events. We suggest that MSC therapy could serve as an effective and safe therapy for clinical application in OA treatment. THE TRANSLATIONAL POTENTIAL OF THIS ARTICLE This study provided the best available evidence and a wider perspective to MSCs application in the management of knee OA. MSCs therapy will have great translational potential in the clinical treatment of various degenerative diseases once optimum formula and explicit target population are identified.

Abstract
OBJECTIVE Measure effect of late-afternoon communication and patient planning (CAPP) rounds to increase early electronic discharge orders (EDO). METHODS We enrolled 4485 patients discharged from six subspecialty medical services. We implemented late-afternoon CAPP rounds to identify patients who could have morning discharge the subsequent day. After an initial successful implementation of the intervention, we identified lack of sustainability. We made changes with sustained implementation of the intervention. This is a before-after study of a quality improvement intervention. PROGRAM EVALUATION Primary measures of intervention effectiveness were percentage of patients who received EDO by 11 am and patients discharged by noon. Additional measure of effectiveness were percent of patients admitted to the correct ward, emergency department (ED)-to-ward transfer time compared between intervention and nonintervention periods. We compared the overall expected LOS and the average weekly discharges to assess for comparability across the control and intervention time periods. We used the readmission rate as balancing measure to ensure that the intervention was not have unintended negative patients consequences. RESULTS Expected length of stay based upon discharge diagnosis/comorbidities and readmission rates were similar across the intervention and control time periods. The average weekly discharges were not statistically significant. Percentage of EDO by 11 am was higher in the first intervention period, second intervention period and combined intervention periods (28.9% vs. 21.8%, P < 0.001) compared with the respective control periods. Percent discharged before noon increased in the first intervention period, second intervention period and for the combined intervention periods (17 vs. 11.8%, P < 0.001). There was no difference in the percent admitted to the correct ward and ED-to-ward transfer time. CONCLUSION Afternoon CAPP rounds to identify early patient discharges the following day led to increase in EDO entered by 11 am and discharges by noon without an adverse change in readmission rates and LOS.

Abstract
Acute myeloid leukemia with myelodysplasia-related changes (AML-MRC) generally confers poor prognosis; however, the clinical outcome remains heterogeneous. We sought to further stratify this subentity of AML by performing a retrospective analysis of 179 adult patients with AML-MRC diagnosed at our institution. Based on 2016 World Health Organization diagnostic criteria, 44 (25%) patients had multilineage dysplasia alone (AML-MRC-M), 74 (41%) had history of myelodysplastic syndrome (MDS) or myelodysplastic/myeloproliferative disease (AML-MRC-H), and 61 (34%) had MDS-related cytogenetics (AML-MRC-C). AML-MRC-M and hematopoietic stem cell transplantation (HSCT) were associated with prolonged event-free survival (EFS) (P = 0.0051 and P < 0.0001, respectively) and overall survival (OS) (P = 0.0015 and P < 0.0001, respectively), whereas AML-MRC-C and age ≥60 years were associated with shorter EFS (P = 0.028 and P = 0.015, respectively) and OS (P = 0.021 and P = 0.013, respectively). Of note, NPM1mut did not affect the patient's outcome. Multivariable analysis confirmed HSCT and AML-MRC-C as independent predictors for EFS (P < 0.0001 and P = 0.0342, respectively) and OS (P < 0.0001 and P = 0.0295, respectively). AML-MRC-M was an independent predictor for OS (P = 0.0449). When compared with a control group of 105 patients with normal karyotype AML not otherwise specified (NK-AML-NOS), patients with AML-MRC-M had similar EFS and OS (P = 0.99 and P = 0.91, respectively). However, AML-MRC-H and AML-MRC-C were associated with shorter EFS and OS (P = 0.0002 and P < 0.0001, respectively) than the same control group. In a subset of patients, next-generation sequencing analysis showed AML-MRC-M was associated with ASXL1 mutation compared with NK-AML (56% vs 6%). In conclusion, AML-MRC-M demonstrates a superior clinical outcome compared with the rest of the AML-MRC group. They have comparable outcomes to NK-AML-NOS, and these data suggest AML-MRC-M may be considered not to be classified in the same group as patients with other AML-MRC.

Abstract
NPM1 mutation status and the allelic ratio (AR) of FLT3-internal tandem duplication (FLT3-ITD) are routinely tested for disease risk stratification in patients with normal karyotype (NK) acute myelogenous leukemia (AML); however, the predictive impact of immunophenotypic markers on different NPM1/FLT3 genotypes remains unclear. We performed a retrospective analysis of 423 patients with NK-AML subclassified into groups based on NPM1/FLT3 genotype. Allogeneic hematopoietic stem cell transplantation (HSCT) was performed in 124 of 423 patients (29%) and was significantly associated with longer event-free survival (EFS) and overall survival (OS), except for patients with the favorable genotype, defined as mutated NPM1 (NPM1mut) combined with normal FLT3 status (FLT3-ITDneg) or FLT3-ITD AR <.5 (FLT3-ITDlow). A subset of AML patients bearing the favorable NPM1mut/FLT3-ITDneg/low genotype share similar outcomes with AML patients who have the intermediate FLT3/NPM1 genotype defined by normal NPM1 (NPM1wt) and FLT3-ITDneg/low. In these individuals, the lack of CD13 expression (CD13neg) was associated with shorter EFS (P = .041) and OS (P = .017). CD13neg was an independent predictor for shorter OS (hazard ratio, 1.985; P = .028).

Abstract
CD47, or integrin-associated protein, is a cell surface ligand expressed in low levels by nearly all cells of the body. It plays an integral role in various immune responses as well as autoimmunity, by sending a potent "don't eat me" signal to prevent phagocytosis. A growing body of evidence demonstrates that CD47 is overexpressed in various hematological malignancies and its interaction with SIRPα on the phagocytic cells prevents phagocytosis of cancer cells. Additionally, it is expressed by different cell types in the tumor microenvironment and is required for establishing tumor metastasis. Overexpression of CD47 is thus often associated with poor clinical outcomes. CD47 has emerged as a potential therapeutic target and is being investigated in various preclinical studies as well as clinical trials to prove its safety and efficacy in treating hematological neoplasms.

Abstract
A high positive magnetoresistance (MR), 78%, is observed at 2 K on the ab plane of the diamagnetic RuSb2+ semiconductor. On the ac plane, MR is 44% at 2 K, and about 7% at 300 K. MR at different temperatures do not follow the Kohler's rule. It suggests that the multiband effect plays a role on the carrier transportation. RuSb2+ is a semiconductor with both positive and negative carriers. The quantum interference effect with the weak localization correction lies behind the high positive MR at low temperature. Judged from the ultraviolet-visible spectra, it has a direct band gap of 1.29 eV. The valence band is 0.39 eV below the Fermi energy. The schematic energy band structure is proposed based on experimental results.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Renal fibrosis (RF) is a common outcome of various progressive chronic kidney diseases (CKDs) and, thus, seriously endangers human health. As the active ingredient of Amygdalus mongolica, amygdalin inhibits RF. Furthermore, our previous studies demonstrated that n-butanol extract (BUT) and petroleum ether extract (PET), which are effective components of A. mongolica, have an anti-renal fibrosis effect. However, their potential mechanisms of action are unclear and need further verification. AIMS OF THE STUDY The aims of this study were to further investigate the effects and potential mechanisms of A. mongolica extracts in the treatment of RF. MATERIALS AND METHODS The animals were divided into the control group, RF model group, PET group and BUT group. The RF rat model was established through unilateral ureteral obstruction (UUO). Biochemical indicators, including blood urea nitrogen (BUN), serum creatinine (Scr), and hydroxyproline (HYP, a routine marker of fibrosis), and the antioxidant index (including superoxide dismutase (SOD) and malondialdehyde (MDA)) were measured to evaluate the anti-RF effects of the extracts of A. mongolica. The histomorphology of renal tissue was observed and scored by HE and Masson staining. A serum metabonomic analysis based on UPLC-Q-TOF/MS was performed to assess the changes in the metabolic profile among the different groups. RESULTS The results showed that PET and BUT significantly improved tubulointerstitial damage and fibrosis by reducing the levels of Scr, BUN, HYP, and MDA and increasing the level of SOD. Moreover, no significant differences in efficacy were observed between the BUT and PET groups. According to the metabolomics analysis, seventy-four potential biomarkers were identified, and eight crucial biomarkers were further selected. These key biomarkers significantly contributed to RF progression by participating in six metabolic pathways, including pathways involved in arginine and proline metabolism, histidine metabolism, nicotinamide metabolism, pentose and glucuronate interconversion, ascorbate and aldarate metabolism, and amino sugar and nucleotide sugar metabolism. In addition, eight key biomarkers and six crucial biomarkers were restored to levels similar to those observed in controls following the treatment with PET and BUT, respectively. CONCLUSIONS The outcomes of these studies demonstrate the renoprotective effects of A. mongolica extracts in rats with RF and revealed the mechanism underlying these antifibrotic effects on metabolic activity for the first time.

Abstract
Recent advances in functional genomics have facilitated the identification of multiple genes and isoforms associated with the genetic risk of schizophrenia, yet the causal variations remain largely unclear. A previous study reported that the schizophrenia risk single-nucleotide polymorphism (SNP) rs7085104 at 10q24.32 was in high linkage disequilibrium (LD) with a human-specific variable number of tandem repeat (VNTR), and both were significantly associated with the brain mRNA expression of a human-unique AS3MTd2d3 isoform in Europeans and African Americans. In this study, we have shown the direct regulation of the AS3MTd2d3 mRNA expression by this VNTR through an in vitro minigene splicing assay, suggesting that it is likely a causative functional variation. Intriguingly, we have further confirmed that the VNTR and rs7085104 are significantly associated with AS3MTd2d3 mRNA expression in brains of Han Chinese donors, and rs7085104 is also associated with risk of schizophrenia in East Asians. Finally, the overexpression of AS3MTd2d3 in cultured primary hippocampal neurons results in significantly reduced densities of mushroom dendritic spines, implicating its potential functional impact. Considering the crucial roles of dendritic spines in neuroplasticity, these results reveal the potential regulatory impact of the schizophrenia risk VNTR on AS3MTd2d3 and provide insights into the underlying biological mechanisms.

Abstract
OBJECTIVE To explore the influences of micro ribonucleic acid (miR)-204 on the rats with diabetic retinopathy by regulating the expressions of B-cell lymphoma 2 (Bcl-2) and sirtuin 1 (SIRT1). MATERIALS AND METHODS A total of 36 Sprague-Dawley rats were randomly assigned into normal group (n=12), model group (n=12), and miR-204 mimics group (n=12). No treatment was performed in the normal group, the diabetic retinopathy model was established in model group, and miR-204 mimics were administered for intervention after modeling in the inhibitor group. After 7 d, materials were sampled for detection. The expressions of Bcl-2 and SIRT1 were detected via immunohistochemistry, and their relative protein expression levels were determined via Western blotting (WB). Quantitative Polymerase Chain Reaction (qPCR) was performed to detect the expression of miR-204, and the content of inflammatory factors interleukin (IL)-6, IL-18, and tumor necrosis factor-α (TNF-α) was measured using enzyme-linked immunosorbent assay (ELISA). Finally, cell apoptosis was evaluated via terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL). RESULTS Immunohistochemistry results showed that the positive expression levels of Bcl-2 and SIRT1 were substantially lower in the model and miR-204 mimics groups than those in the normal group (p<0.05), and their positive expression levels in miR-204 mimics group were notably higher than those in model group (p<0.05). According to Western blot (WB) results, the relative protein expression levels of Bcl-2 and SIRT1 markedly declined in the other two groups compared with those in the normal group (p<0.05), while miR-204 mimics group exhibited remarkably higher relative protein expression levels of Bcl-2 and SIRT1 than the model group (p<0.05). The results of qPCR revealed that the relative expression level of miR-204 was markedly lowered in model and miR-204 mimics groups compared with that in the normal group (p<0.05), and its relative expression level in miR-204 mimics group was remarkably higher than that in the model group. It was found through enzyme-linked immunosorbent assay (ELISA) that compared with normal group, the other two groups had substantially increased content of IL-6, IL-18, and TNF-α (p<0.05), and the content of IL-6, IL-18, and TNF-α in miR-204 mimics group was markedly lower than that in the model group (p<0.05). According to TUNEL results, the apoptosis rate of cells rose substantially in the other two groups compared with that in the normal group (p<0.05), while was notably lower in the miR-204 mimics group than that in the model group (p<0.05). CONCLUSIONS MiR-204 up-regulates Bcl-2 and SIRT1 expressions to inhibit the inflammation and cell apoptosis in rats with diabetic retinopathy.

Abstract
Purpose The present study aimed to investigate the prognostic effect of PD-L1 expressing in tumor and immune cells among patients with esophageal squamous cell carcinoma. Patients and Methods We performed a retrospective cohort study by consecutively recruiting 142 patients. The clinicopathological features and PD-L1 expression on tumor and immune cells were independently evaluated by two pathologists. Results The median expression rate of PD-L1 was 5% and 30% in tumor and immune cells, respectively. Patients with higher expression of PD-L1 in tumor cells had shorter disease-free and overall survival, and the HRs were 1.52 for relapse (95% CI: 0.88, 2.60) and 1.48 for death (95% CI: 0.82, 2.69). There was no significant association between the PD-L1 expression in immune cells and survival. However, among the patients with PD-L1 expression rate ≤30% in immune cells, the high expression rate of PD-L1 in tumor cells was significantly associated with the relapse and death, with HRs of 2.51 (95% CI: 1.25, 5.06) and 3.51 (95% CI: 1.57, 7.85), respectively. Among patients with PD-L1 expression rate >30% in immune cells, the PD-L1 expression in tumor cells did not show any association with the disease-free and overall survival. Conclusion Our study demonstrates that the integration of PD-L1 expression in tumor and immune cells could be used to predict the relapse and survival among patients with esophageal squamous cell carcinoma.

Abstract
Interruption of the programmed death 1 (PD-1) / programmed death ligand 1 (PD-L1) pathway is an established and effective therapeutic strategy in human oncology and holds promise for veterinary oncology. We report the generation and characterization of monoclonal antibodies specific for canine PD-1 and PD-L1. Antibodies were initially assessed for their capacity to block the binding of recombinant canine PD-1 to recombinant canine PD-L1 and then ranked based on efficiency of binding as judged by flow cytometry. Selected antibodies were capable of detecting PD-1 and PD-L1 on canine tissues by flow cytometry and Western blot. Anti-PD-L1 worked for immunocytochemistry and anti-PD-1 worked for immunohistochemistry on formalin-fixed paraffin embedded canine tissues, suggesting the usage of this antibody with archived tissues. Additionally, anti-PD-L1 (JC071) revealed significantly increased PD-L1 expression on canine monocytes after stimulation with peptidoglycan or lipopolysaccharide. Together, these antibodies display specificity for the natural canine ligand using a variety of potential diagnostic applications. Importantly, multiple PD-L1-specific antibodies amplified IFN-γ production in a canine peripheral blood mononuclear cells (PBMC) concanavlin A (Con A) stimulation assay, demonstrating functional activity.

Abstract
Fabrication of osteoconductive scaffold with osteoinductive capability and appropriate resorption rate is of great significance for treating bone defects. To achieve this aim, strontium-substituted calcium sulfate hemihydrate (Sr-CSH) and hydroxyapatite (HA) were mixed to develop a novel composite. Sr-CSH containing 5% and 10% strontium was mixed with HA at the weight ratio of 6:4, respectively. Female Sprague-Dawley rats underwent bone defect surgery in left tibia were randomly assigned to three different treatment groups filled with CSH/HA, 5% and 10% Sr-CSH/HA. Micro-CT analysis showed increased new bone formation in 10% Sr-CSH/HA group compared to CSH/HA group. In addition, histological analysis showed large amounts of chondrocytes and osteoblasts within the pores of Sr-CSH/HA composites as a result of the CSH resorption. Further, CFU-F assay demonstrated the increased amount of bone marrow mesenchymal stromal cells (BMSCs) colonies in 10% Sr-CSH/HA group. In primary BMSCs, extraction from Sr-CSH/HA composite significantly increased the migration of cells, up-regulated the expression of osteoblastic marker genes, and increased the area of mineralized nodules. Together, Sr-CSH/HA may promote bone formation by recruiting and stimulating osteogenic differentiation of BMSCs. Therefore, this composite may be proposed as an ideal substitute to repair bone defects.

Abstract
The pandemic coronavirus SARS-CoV-2 in the world has caused a large infected population suffering from COVID-19. To curb the spreading of the virus, WHO urgently demanded an extension of screening and testing; thus, a rapid and simple diagnostic method is needed. We applied a reverse transcription-loop-mediated isothermal amplification (RT-LAMP) to achieve the detection of SARS-CoV-2 in 30 min. We designed four sets of LAMP primers (6 primers in each set), targeting the viral RNA of SARS-CoV-2 in the regions of orf1ab, S gene and N gene. A colorimetric change was used to report the results, which enables the outcome of viral RNA amplification to be read by the naked eye without the need of expensive or dedicated instrument. The sensitivity can be 80 copies of viral RNA per ml in a sample. We validated the RT-LAMP method in a hospital in China, employing 16 clinic samples with 8 positives and 8 negatives. The testing results are consistent with the conventional RT-qPCR. In addition, we also show that one-step process without RNA extraction is feasible to achieve RNA amplification directly from a sample. This rapid, simple and sensitive RT-LAMP method paves a way for a large screening at public domain and hospitals, particularly regional hospitals and medical centres in rural areas.

Abstract
To fully exploit van der Waals materials and their vertically stacked heterostructures, new mass-scalable production routes which are low cost but preserve the high electronic and optical quality of the single crystals are required. Here, we demonstrate an approach to realise a variety of functional heterostructures based on van der Waals nanocrystal films produced through the mechanical abrasion of bulk powders. We find significant performance enhancements in abraded heterostructures compared to those fabricated through inkjet printing of nanocrystal dispersions. To highlight the simplicity, applicability and scalability of the device fabrication, we demonstrate a multitude of different functional heterostructures such as resistors, capacitors and photovoltaics. We also demonstrate the creation of energy harvesting devices, such as large area catalytically active coatings for the hydrogen evolution reaction and enhanced triboelectric nanogenerator performance in multilayer films. The ease of device production makes this a promising technological route for up-scalable films and heterostructures. Low-cost, mass-scalable production routes which preserve the quality of the single crystals are required to up-scale van der Waals materials. Here, the authors demonstrate an approach to realise a variety of functional heterostructures based on van der Waals nanocrystal films produced through the mechanical abrasion of bulk powders.

Abstract
CKB3 is a regulatory (beta) subunit of CK2. In this study Arabidopsis thaliana homozygous T-DNA mutant ckb3 was studied to understand the role of CKB3 in abscisic acid (ABA) signaling. The results shown: CKB3 was expressed in all organs and the highest expression in the seeds, followed by the root. During seed germination and root growth the ckb3 mutant showed reduced sensitivity to ABA. The ckb3 mutant had more stomatal opening and increased proline accumulation and leaf water loss. The expression levels of number of genes in the ABA regulatory network had changed. This study demonstrates that CKB3 is an ABA signaling-related gene and may play a positive role in ABA signaling.

Abstract
Genome-wide association studies (GWAS) have reported substantial single-nucleotide polymorphisms (SNPs) associated with major depressive disorder (MDD), but the underlying functional variations in the GWAS risk loci are unclear. Here we show that the European MDD genome-wide risk-associated allele of rs12129573 at 1p31.1 is associated with MDD in Han Chinese, and this SNP is in strong linkage disequilibrium (LD) with a human-unique Alu insertion polymorphism (rs70959274) in the 5' flanking region of a long non-coding RNA (lncRNA) LINC01360 (Long Intergenic Non-Protein Coding RNA 1360), which is preferably expressed in human testis in the currently available expression datasets. The risk allele at rs12129573 is almost completely linked with the absence of this Alu insertion. The Alu insertion polymorphism (rs70959274) is significantly associated with a lower RNA level of LINC01360 and acts as a transcription silencer likely through modulating the methylation of its internal CpG sites. Luciferase assays confirm that the presence of Alu insertion at rs70959274 suppresses transcriptional activities in human cells, and deletion of the Alu insertion through CRISPR/Cas9-directed genome editing increases RNA expression of LINC01360. Deletion of the Alu insertion in human cells also leads to dysregulation of gene expression, biological processes and pathways relevant to MDD, such as the alterations of mRNA levels of DRD2 and FLOT1, transcription of genes involved in synaptic transmission, neurogenesis, learning or memory, and the PI3K-Akt signaling pathway. In summary, we identify a human-unique DNA repetitive polymorphism in robust LD with the MDD risk-associated SNP at the prominent 1p31.1 GWAS loci, and offer insights into the molecular basis of the illness.

Abstract
We present an example of applying ‘need-driven’ product design principle to the development of a rapid test kit to detect SARS-COV-2 (COVID-19). The tests are intended for use in the field and, longer term, for home use. They detect whether a subject is currently infected with the virus and is infectious. The urgent need for large numbers of tests in field setting imposes constraints such as short test time and lack of access to specialist equipment, laboratories and skilled technicians to perform the test and interpret results. To meet these needs, an antigen test based on RT-LAMP with colorimetric readout was chosen. Direct use of swab sample with no RNA extraction was explored. After extensive experimental study (reported elsewhere), a rapid test kit has been fabricated to satisfy all design criteria.

Abstract
Purpose
Smart home (SH) internet of things can promote home safety, health monitoring and independence of older adults to age-in-place. Despite its commercial growth, low adoption rates of the technology among aging consumers remain a major barrier. The purpose of this study is to examine SH technology ownership of older adults and its causal pathways with demographics, health and functioning, home safety and information communication technology (ICT) use.
Design/methodology/approach
A survey on technology-mediated aging-in-place was completed by 447 respondents, 65 years and older. Structural equation modeling was used to underscore the causal pathways among demographics, health, independence and home safety, ICT and home automation technology adoption.
Findings
The study found that ICT usability, home security and independence have a significant direct effect on SH ownership. Demographics had no significant direct effect, but its influence was mediated through ICT usability. With home safety as mediator, physical impairment, falls and accidents and independence had a significant association with SH ownership. Similarly, increased social support (mediated through home security) decreased the probability of SH automation ownership.
Originality/value
The findings signify the perceived usefulness of SH automation as theorized in technology acceptance models.

Abstract
OBJECTIVE We explored whether medical health workers had more psychosocial problems than nonmedical health workers during the COVID-19 outbreak. METHODS An online survey was run from February 19 to March 6, 2020; a total of 2,182 Chinese subjects participated. Mental health variables were assessed via the Insomnia Severity Index (ISI), the Symptom Check List-revised (SCL-90-R), and the Patient Health Questionnaire-4 (PHQ-4), which included a 2-item anxiety scale and a 2-item depression scale (PHQ-2). RESULTS Compared with nonmedical health workers (n = 1,255), medical health workers (n = 927) had a higher prevalence of insomnia (38.4 vs. 30.5%, p < 0.01), anxiety (13.0 vs. 8.5%, p < 0.01), depression (12.2 vs. 9.5%; p< 0.04), somatization (1.6 vs. 0.4%; p < 0.01), and obsessive-compulsive symptoms (5.3 vs. 2.2%; p < 0.01). They also had higher total scores of ISI, GAD-2, PHQ-2, and SCL-90-R obsessive-compulsive symptoms (p ≤ 0.01). Among medical health workers, having organic disease was an independent factor for insomnia, anxiety, depression, somatization, and obsessive-compulsive symptoms (p < 0.05 or 0.01). Living in rural areas, being female, and being at risk of contact with COVID-19 patients were the most common risk factors for insomnia, anxiety, obsessive-compulsive symptoms, and depression (p < 0.01 or 0.05). Among nonmedical health workers, having organic disease was a risk factor for insomnia, depression, and obsessive-compulsive symptoms (p < 0.01 or 0.05). CONCLUSIONS During the COVID-19 outbreak, medical health workers had psychosocial problems and risk factors for developing them. They were in need of attention and recovery programs.

Abstract
Overexpression of Myristoylated Alanine-Rich C Kinase Substrate (MARCKS) is implicated in drug resistance and progression of multiple myeloma (MM). The basis for MARCKS induction and impact on MM are not known. Here we show that microRNA-34a (miR-34a), regulates MARCKS translation and is under-expressed in drug-resistant MM cells, leading to increased MARCKS protein level. Over-expression of miR-34a reduces MARCKS expression and sensitizes resistant cells to anti-myeloma drugs. A MARCKS peptide inhibitor (MPS) exerts a dose dependent cytotoxic effect on drug-resistant MM cells with minimal cytotoxicity to normal hematopoietic cells. MPS synergizes with the proteasomal-inhibitor bortezomib to effectively kill drug-resistant MM cells both in vitro and in a xenograft model of MM. While MARCKS inhibition killed MM cells, it also enhanced a pro-survival autophagic pathway that sustained growth following MARCKS inhibition. In accordance, combined treatment with MARCKS antagonists, bortezomib and the autophagy inhibitor, chloroquine, significantly diminished tumor growth in drug-resistant MM cell lines as well as primary MM cells. This study uncovers a mechanism of drug resistance involving miR-34a-MARCKS autoregulatory loop and provides a framework for a potentially new therapeutic strategy to overcome drug resistance in multiple myeloma.

Abstract
A variety of anthropogenic chemicals can disrupt the equilibrium of intrinsic biological metabolites in organisms, leading to metabolic disorders and an increased risk of metabolic syndromes. However, exposure to pollutants that induce metabolic disorders in wildlife as a cause of adverse effects is unknown. In this study, approximately 3108 compounds, including 11 groups of metabolites and 388 pollutants, were simultaneously identified in the blood of wild crucian carp (Carassius auratus) captured in three bays of Taihu Lake, China. A visualized network linking thousands of co-regulated metabolites was automatically produced for the screened signals. This comprehensive view of the differences in blood metabolite profiles in carp from the north and south bays showed that triglycerides (TGs) were the intrinsic molecules most affected by differing environmental pollution in each bay. The regional differences in metabolite profiles were linked to exposure to screened perfluorinated compounds that displayed corresponding regional differences in concentrations and effects on TGs in in vivo exposure tests. Perfluoroundecanoic acid (PFUnDA) was the key pollutant responsible for the variation in blood TGs in wild crucian carp, and exposure to PFUnDA resulted in extremely high biological activity on lipid deposition in the liver tissues of crucian carp at environmental levels.

Abstract
Background Qishen granules (QSG) has been applied to treat heart failure (HF) for decades. Our previous transcriptomics study has suggested that Qishen granules (QSG) could regulate the pathways of cardiac energy metabolism in HF, but the specific regulatory mechanism has not yet been clarified. This study was to investigate the potential mechanism of QSG in regulating myocardial fatty acid (FA) and glucose metabolism in a rat model of HF. Methods The model of HF was induced by left anterior descending coronary artery ligation. Cardiac structure and function were assessed by cine magnetic resonance imaging (MRI) and echocardiography. Level of glucose metabolism was non-invasively evaluated by 18F-fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT). Blood lipid levels were determined by enzymatic analysis. The mitochondrial ultrastructure was observed with a transmission electron microscope. The critical proteins related to FA metabolism, glucose metabolism and mitochondrial function were measured by western blotting. The ANOVA followed by a Fisher’s LSD test was used for within-group comparisons. Results QSG ameliorated cardiac functions and attenuated myocardial remodeling in HF model. The levels of serum TC, TG and LDL-C were significantly reduced by QSG. The proteins mediating FA uptake, transportation into mitochondria and β-oxidation (FAT/CD36, CPT1A, ACADL, ACADM, ACAA2 and SCP2) as well as the upstreaming transcriptional regulators of FA metabolism (PPARα, RXRα, RXRβ and RXRγ) were up-regulated by QSG. As to glucose metabolism, QSG inhibited glycolytic activity by decreasing LDHA, while stimulated glucose oxidation by decreasing PDK4. Furthermore, QSG could facilitate tricarboxylic acid cycle, promote the transportation of ATP from mitochondria to cytoplasm and restore the mitochondrial function by increasing SUCLA2, CKMT2 and PGC-1α and decreasing UCP2 simultaneously. Conclusion QSG improved myocardial energy metabolism through increasing FA metabolism,inhibiting uncoupling of glycolysis from glucose oxidation.

Abstract
OBJECTIVES To obtain information about alcohol consumption (henceforth "drinking") among Chinese adults from 1991 to 2011, and to explore the association between drinking behavior and hypertension. METHODS According to the longitudinal data obtained in the China Health and Nutrition Survey (1991-2011), 50,013 records of 12,577 adults were selected by applying eligibility criteria. The chi-test was employed to explore the association between drinking and hypertension, by considering the frequency of drinking, daily alcohol intake, alcohol type, and the prevalence of hypertension. A multilevel logistic regression model was used to analyze the longitudinal association between drinking frequency and the prevalence of hypertension. RESULTS The prevalence of hypertension was higher in participants with a high drinking frequency than in those with a low drinking frequency among both males and females (p < 0.001). A step increase in daily alcohol intake was not associated with any obvious changes in the prevalence of hypertension in males, but the prevalence in each drinking group was higher than that in the nondrinking group, the prevalence of hypertension in females was lowest among those with a daily alcohol intake below 15 g. The types of alcohol consumed differed significantly between males and females (p < 0.001). Longitudinal analysis results showed that compared with the nondrinking group, drinking frequency ≤2 times/week was positively correlated with hypertension in both males (OR = 1.51, 95% CI = 1.26-1.82, p < 0.001) and females (OR = 1.67, 95% CI = 1.08-2.58, p < 0.05) after adjusting for covariates, meanwhile, the same positive correlation also occurred in males with drinking frequency >2 times/week (OR = 2.13, 95% CI = 1.77-2.56, p < 0.05), the risk of hypertension increased with the increase in drinking frequency. CONCLUSIONS Drinking can increase the prevalence of hypertension in Chinese males and females. From the analysis results of longitudinal data, drinking alcohol is still an important risk factor for hypertension among Chinese subjects, especially those who drink with high frequency.

Abstract
The purpose of the current study was to examine the impact of exposure to Bringing in the Bystander-High School Curriculum (BITB-HSC) on school personnel, which included a seven session classroom curriculum for ninth through twelfth graders (student curriculum), a bystander training workshop for school personnel (school personnel workshop), and reading materials (handout). We examined how exposure to these various BITB-HSC intervention components was associated with school personnel's knowledge and bystander efficacy, intentions, and barriers specific to student relationship abuse (RA) and sexual assault (SA). Participants were 488 school personnel from 12 high schools in upper New England who completed the 4-month follow-up survey that assessed for intervention exposure (284 participants completed both the baseline and follow-up survey). Whereas 53% of participants were exposed to no intervention components, the other half of the sample were exposed to a combination of intervention components. Higher baseline knowledge and reactive bystander intentions were associated with subsequent exposure to both the student curriculum and the handout, and fewer barriers to bystander action predicted exposure to the school personnel workshop. Exposure to the school personnel workshop, student curriculum, and handout was associated with subsequent greater knowledge, exposure to the student curriculum predicted reactive bystander intentions, and exposure to the handout predicted higher reactive bystander intentions and bystander efficacy. Findings suggest that despite challenges with engagement, exposure to the BITB-HSC components may be a useful tool in improving school personnel's responses to RA and SA among high school students.
