Abstract
Sarcopenia and frailty are highly prevalent conditions in older hospitalized patients, which are associated with a myriad of adverse clinical outcomes. This paper, prepared by a multidisciplinary expert working group from the Australian and New Zealand Society for Sarcopenia and Frailty Research (ANZSSFR), provides an up-to-date overview of current evidence and recommendations based on a narrative review of the literature for the screening, diagnosis, and management of sarcopenia and frailty in older patients within the hospital setting. It also includes suggestions on potential pathways to implement change to encourage widespread adoption of these evidence-informed recommendations within hospital settings. The expert working group concluded there was insufficient evidence to support any specific screening tool for sarcopenia and recommends an assessment of probable sarcopenia/sarcopenia using established criteria for all older (≥65 years) hospitalized patients or in younger patients with conditions (e.g., comorbidities) that may increase their risk of sarcopenia. Diagnosis of probable sarcopenia should be based on an assessment of low muscle strength (grip strength or five times sit-to-stand) with sarcopenia diagnosis including low muscle mass quantified from dual energy X-ray absorptiometry, bioelectrical impedance analysis or in the absence of diagnostic devices, calf circumference as a proxy measure. Severe sarcopenia is represented by the addition of impaired physical performance (slow gait speed). All patients with probable sarcopenia or sarcopenia should be investigated for causes (e.g., chronic/acute disease or malnutrition), and treated accordingly. For frailty, it is recommended that all hospitalized patients aged 70 years and older be screened using a validated tool [Clinical Frailty Scale (CFS), Hospital Frailty Risk Score, the FRAIL scale or the Frailty Index]. Patients screened as positive for frailty should undergo further clinical assessment using the Frailty Phenotype, Frailty Index or information collected from a Comprehensive Geriatric Assessment (CGA). All patients identified as frail should receive follow up by a health practitioner(s) for an individualized care plan. To treat older hospitalized patients with probable sarcopenia, sarcopenia, or frailty, it is recommended that a structured and supervised multi-component exercise program incorporating elements of resistance (muscle strengthening), challenging balance, and functional mobility training be prescribed as early as possible combined with nutritional support to optimize energy and protein intake and correct any deficiencies. There is insufficient evidence to recommend pharmacological agents for the treatment of sarcopenia or frailty. Finally, to facilitate integration of these recommendations into hospital settings organization-wide approaches are needed, with the Spread and Sustain framework recommended to facilitate organizational culture change, with the help of 'champions' to drive these changes. A multidisciplinary team approach incorporating awareness and education initiatives for healthcare professionals is recommended to ensure that screening, diagnosis and management approaches for sarcopenia and frailty are embedded and sustained within hospital settings. Finally, patients and caregivers' education should be integrated into the care pathway to facilitate adherence to prescribed management approaches for sarcopenia and frailty.

Abstract
Lithium disilicate (LD) glass-ceramics with a stoichiometric composition were ion-exchanged in pure NaNO3 or mixed NaNO3 + KNO3 molten salt baths below the glass transition temperature (Tg). The microstructures, surface morphologies, mechanical properties and bioactivities of the ion-exchanged glass-ceramics were studied in detail. It was found that the strength and toughness of LD glass-ceramic could be enhanced from 175 MPa to 0.96 MPa m1/2 before ion-exchange to 546 MPa and 4.31 MPa m1/2 respectively under a lowered ion-exchange temperature because the less stress relaxation. In addition, a gradient of Na+ rich layer in the surface of glass-ceramic was induced by Li+/Na+ exchange, which could be beneficial to the formation of HA (Hydroxyapatite) with nano-size porous after soaking in SBF (Simulated Body Fluid) solution and exhibited better bioactivity compared with the original LD glass-ceramic. The results might provide a reference for the strengthening and biological activation of LD glass-ceramics in bone restoration applications.

Abstract
This Letter reports results from the first long-baseline search for sterile antineutrinos mixing in an accelerator-based antineutrino-dominated beam. The rate of neutral-current interactions in the two NOvA detectors, at distances of 1 and 810 km from the beam source, is analyzed using an exposure of 12.51×10^{20} protons-on-target from the NuMI beam at Fermilab running in antineutrino mode. A total of 121 of neutral-current candidates are observed at the far detector, compared to a prediction of 122±11(stat.)±15(syst.) assuming mixing only between three active flavors. No evidence for ν[over ¯]_{μ}→ν[over ¯]_{s} oscillation is observed. Interpreting this result within a 3+1 model, constraints are placed on the mixing angles θ_{24}<25° and θ_{34}<32° at the 90% C.L. for 0.05 eV^{2}≤Δm_{41}^{2}≤0.5 eV^{2}, the range of mass splittings that produces no significant oscillations at the near detector. These are the first 3+1 confidence limits set using long-baseline accelerator antineutrinos.

Abstract
Abstract
Background
Heart failure (HF) evolves as a global pandemic and strains the over-stretched hospital service. Ineffective self-care remains the key factor to explain the avoidable hospital admission. Patient empowerment is as a theory-based strategy to optimize the patients' self-care changes for disease management [1]. Its cost-effectiveness to enhance self-care and health service utilization has yet to be determined.
Purpose
This was a double-blind randomized controlled trial to compare the effects and cost-effectiveness of a 12-week empowerment self-care program with a didactic education program on self-care maintenance and management as well as health service utilization among the community-dwelling HF patients.
Methods
A total of 236 HF patients were recruited from the specialist clinics of the Department of Cardiology in two regional hospitals. They were randomized to receive either the 12-week empowerment self-care program (Figure 1) or the 12-week didactic education. Outcome evaluation using the Self-care Heart Failure Index (SCHFI) at baseline, post-intervention (T1) and three months thereafter (T2), with record on the number of emergency room (ER) attendance and hospital admission. Cost effectiveness analyses were performed on total cost (medical, intervention and societal costs) incurred in both interventions as well as incremental cost-effectiveness ratios (ICER) expressed as incremental cost per 1) a reflected clinically meaningful improvement in self-care (i.e. a half standard deviation increase in SCHFI), 2) an ER attendance reduced, 3) a day of hospital stay reduced.
Results
As compared with the education group, the empowerment group reported significantly greater improvement in self-care management at T1 [B=13.77 (95% CI=6.07, 21.46), p<0.001] and T2 [B=10.98 (95% CI=3.21, 18.75), p=0.006]. For cost-effective analysis, The ICER (empowerment-education) was −USD220/0.5 SD increase in SCHFI, indicating the mean cost saved per patient for making a clinically significant improvement in self-care was USD 220. The cost-effectiveness acceptability curve showed patients were willing to pay at USD 207- 441 for a 80–90% chance of improved self-care, indicating that the empowerment approach was a cost saving strategy. Although the empowerment approach was associated with a lower risk of ER attendance [IRR=0.55, 95% CI=0.31–0.95)] and hospital admission [IRR=0.38 (95% CI=0.31–0.95)], it is not cost saving for reducing hospital service utilization.
Conclusions
The empowerment-based self-care program is a cost-saving strategy to produce a clinical significant change in HF-related self-care. Although it is associated with lower risk for hospital service utilization, its effect is not significant enough to be cost-saving. Future care model may explore the need to integrate dyadic science [2] and e-health [3] to strengthen the care continuity and effects of self-care intervention.

Abstract
OBJECTIVE To clarify the biological function of miRNA-128-3p in influencing the progression of osteoporosis by inducing osteogenic differentiation of MSCs via activating the Wnt3a signaling. PATIENTS AND METHODS Dynamic expression levels of miRNA-128-3p in osteogenically differentiated MSCs at the different time points were detected by qRT-PCR. The binding sites in the seed sequence of miRNA-128-3p and Wnt3a were predicted using the bioinformatic tool, and their interaction was further confirmed by Dual-Luciferase reporter assay. Co-regulation of miRNA-128-3p and Wnt3a on relative levels of osteogenesis-associated genes, ALP activity and mineralization ability in glucocorticoid-induced MSCs were assessed. RESULTS MiRNA-128-3p was gradually upregulated with the prolongation of osteogenic differentiation of MSCs. Overexpression of miRNA-128-3p reversed the declines in glucocorticoid-induced expression levels of osteogenesis-associated genes (Bglap, RUNX2 and BMP-2), ALP activity and mineralization ability in MSCs. Wnt3a was able to bind miRNA-128-3p. Its level was positively regulated by miRNA-128-3p in MSCs. Enhanced ALP activity and mineralization ability in glucocorticoid-induced MSCs overexpressing Wnt3a were partially abolished by knockdown of miRNA-128-3p. CONCLUSIONS By positively regulating Wnt3a, miRNA-128-3p alleviates the progression of osteoporosis through inducing osteogenic differentiation of MSCs.

Abstract
OBJECTIVE To explore the suppressing impact of low phosphorus intake on osteoarthritic temporomandibular joint and the possible mechanisms of nuclear acid injury in the insulted chondrocytes. DESIGN Chondrocytes were loaded with fluid flow shear stress (FFSS) with or without low phosphorus medium. Seventy-two mice (sampled at 3-, 7- and 11-wk, n = 6) and forty-eight rats (sampled at 12-wks for different testing purpose, n = 6) were applied with unilateral anterior crossbite (UAC) with or without low phosphorus diet. In the FFSS model, the Ca and P content, molecules related to nucleic acid degradation and the mineral-producing responses in chondrocytes were detected. The effect of culture dish stiffness on chondrocytes osteogenic differentiation was measured. In the UAC model, the content of Ca and P in serum were tested. The condylar cartilage ossification and stiffness were detected using micro-CT, scanning electron microscope and atomic force microscope. RESULTS FFSS induced nucleic acid degradation, Pi accumulation and mineral-producing responses in the cultured chondrocytes, all were alleviated by low P medium. Stiffer dish bottoms promoted the osteogenic differentiation of the cultured chondrocytes. UAC stimulated cartilage degeneration and chondrocytes nucleic acid damage, increased PARP 1 and serum P content, and enhanced ossification and stiffening of the cartilage, all were suppressed by low phosphorus diet (all, P < 0.05). CONCLUSION Nucleic acid damage takes a role in phosphorus production in osteoarthritic cartilage, contributing to the enhanced mineralization and stiffness of the cartilage that in turn promotes cartilage degradation, which can be alleviated by low phosphorus intake.

Abstract
We investigated changes in concentrations of ADP (adiponectin), LEP (leptin), BHBA (beta-hydroxybutyric acid), NEFA (non-esterified fatty acid), Glucose (Glu) and INS (insulin) in serum of healthy perinatal dairy cows and cows with ketosis. Twenty-one healthy cows and seventeen cows with ketosis from a herd of a total 60 Holstein cows (near dry period i.e. 56 days antepartum) were selected. Blood was collected through the tail vein every 7 days, from 56 day antepartum to 56 day postpartum. Serum ADP, LEP, BHBA, NEFA, Glu, and INS concentrations were determined, and ketosis was diagnosed through serum BHBA (≥1.2 mmol/L). We showed the concentration of serum adipokines and energy balancing indices were stable during antepar- tum period. However, ADP concentration increased while LEP decreased, and there were a significant increase in cows with ketosis compared to that of in healthy cows. Serum BHBA and NEFA concentrations increased significantly at first, and then gradually decreased in both healthy cows and cows with ketosis. However, cows with ketosis showed higher concentrations of BHBA and NEFA which restored later. The serum concentration of Glu in both healthy dairy cows and cows with ketosis showed a decreasing trend. INS concentration in healthy cows was decreased while it was increased in cows with ketosis. The results reflect the extent of hypo- glycemia and lipid mobilization postpartum, suggest IR exists in cows with ketosis while serum ADP and LEP might play roles in the development of ketosis.

Abstract
Orthodontic tooth movement (OTM) depends on periodontal ligament cells (PDLCs) sensing biomechanical stimuli and subsequently releasing signals to initiate alveolar bone remodeling. However, the mechanisms by which PDLCs sense biomechanical stimuli and affect osteoclastic activities are still unclear. This study demonstrates that the core circadian protein aryl hydrocarbon receptor nuclear translocator-like protein 1 (BMAL1) in PDLCs is highly involved in sensing and delivering biomechanical signals. Orthodontic force upregulates BMAL1 expression in periodontal tissues and cultured PDLCs in manners dependent on ERK (extracellular signal-regulated kinase) and AP1 (activator protein 1). Increased BMAL1 expression can enhance secretion of CCL2 (C-C motif chemokine 2) and RANKL (receptor activator of nuclear factor-κB ligand) in PDLCs, which subsequently promotes the recruitment of monocytes that differentiate into osteoclasts. The mechanistic delineation clarifies that AP1 induced by orthodontic force can directly interact with the BMAL1 promoter and activate gene transcription in PDLCs. Localized administration of the ERK phosphorylation inhibitor U0126 or the BMAL1 inhibitor GSK4112 suppressed ERK/AP1/BMAL1 signaling. These treatments dramatically reduced osteoclastic activity in the compression side of a rat orthodontic model, and the OTM rate was almost nonexistent. In summary, our results suggest that force-induced expression of BMAL1 in PDLCs is closely involved in controlling osteoclastic activities during OTM and plays a vital role in alveolar bone remodeling. It could be a useful therapeutic target for accelerating the OTM rate and controlling pathologic bone-remodeling activities.

Abstract
Background:Idiopathic inflammatory myopathy (IIM), also known as myositis, refers to a group of heterogeneous disorders including polymyositis (PM), dermatomyositis (DM), inclusion body myositis and immune-mediated necrotising myopathy. Phenotype, pathogenesis, and prognosis vary due to multi-organ involvement and comorbidities. With the clinical application of MSAs, a new classification system for myositis was explored to reduce confusion between subgroups. But it is far from showing the full picture of myositis due to high heterogeneity. Therefore, it is necessary to systematically evaluate the relevant risk factors of myositis for ILD, other rheumatic diseases, and malignancy for better clinical vigilance. And further exploring the subclassification of myositis is critical.Objectives:To identify the risk factors in Chinese patients with adult polymyositis and dermatomyositis for their comorbidities and explore a subclassification system.Methods:Clinical records of 397 patients with idiopathic inflammatory myopathies were retrospectively reviewed. Logistic regression was used to identify potential risk factors for interstitial lung disease (ILD), other rheumatic diseases, and malignancy after bivariate analysis. Hierarchical clustering and decisional tree were utilized to identify subgroups and explore a subclassification system.Results:A total of 119 polymyositis and 191 dermatomyositis patients were included. Anti-PM/Scl, anti-Ro52, anti-aminoacyl-tRNA synthetase and anti-MDA5 (adjusted odds ratios (AOR)=4.779, 1.917, 5.092 and 7.714 respectively) antibodies were risks (p<0.05), whereas overlapping malignancy was protective (AOR=0.107; p=0.002) for ILD across polymyositis, dermatomyositis and the total group. In subgroup models, Raynaud’s phenomenon, arthralgia and semi-quantitative anti-nuclear antibody (AOR=51.233, 4.261, 3.047 respectively) were risks for other overlapping rheumatic diseases (p<0.05). For overlapping malignancy, male and anti-TIF1γ antibodies (AOR=2.533, 16.949) were risks (p<0.05), whereas disease duration and combination of ILD (AOR=0.954, 0.106) were protective in the total group (p<0.05); while anti-NXP2 antibodies were identified as risk factors (AOR=73.152; p=0.038) in polymyositis. Hierarchical clustering suggested a subclassification with 6 subgroups: malignancy overlapping dermatomyositis, classical dermatomyositis, polymyositis with severe muscle involvement, dermatomyositis with ILD, polymyositis with ILD, and overlapping of myositis with other rheumatic diseases according to the characteristics of grouped patients. Accuracy of the classification and regression trees model was 0.768 (95% CI 0.711 to 0.819) on training set and 0.633 (95%CI 0.499 to 0.754) on test set.Conclusion:Accompanying ILD, other rheumatic diseases and malignancy are strongly associated with clinical manifestation and myositis-specific or myositis-associated autoantibodies among Chinese polymyositis and dermatomyositis patients. The subclassification system proposed a more precise phenotype defining toward stratified treatments.Acknowledgements:The study was supported by the Natural Science Foundation of China [No. 81803932] and the Natural Science Foundation of Guangdong Province [No. 2018030310025 and 2017A030313868].

Abstract
Objective: To compare the clinicopathological characteristics and the prognosis of gastric adenocarcinoma patients with and without neuroendocrine differentiation (NED) after radical gastrectomy plus D2 lymph node dissection. Methods: A retrospective cohort study was performed. The inclusion criteria were as follows: (1) patients who underwent radical resection of gastric cancer plus D2 lymph node dissection and were confirmed as gastric adenocarcinoma by postoperative pathology and received immunohistochemical examination of neuroendocrine markers Syn and/or CgA; (2) patients aged 20 to 75 years with normal organ function; (3) patients who did not receive neoadjuvant chemotherapy or radiotherapy before operation; (4) patients with postoperative pathological stage I to III according to the 8th edition of tumor staging system of American Joint Committee on Cancer (AJCC); and (5) patients who completed adjuvant chemotherapy according to the postoperative pathological stage. Those who had other malignant tumors in the past 5 years and who could not be followed up according to the required rules were excluded. According to the above criteria, the clinicopathological characteristics of gastric cancer patients who underwent radical resection plus D2 lymph node dissection in Zhongshan Hospital of Fudan University from January 2010 to June 2017 were collected and compared. All patients were followed up till June 2020. The disease-free survival (DFS) and overall survival (OS) between the patients with and without NED were compared, and the effect of NED on the prognosis was corrected by Cox proportional hazards model. The propensity score matching method was used for sensitivity analysis. Results: A total of 539 patients were enrolled in this study, including 35 with NED and 504 without NED. Compared with the patients without NED, the patients with NED were older [(65.0±7.5) years vs. (54.5±11.3) years, t=-7.681, P<0.001], had higher proportion of undergoing proximal gastrectomy [22.9% (8/35) vs. 7.6% (36/504), χ(2)=10.335, P=0.006], higher proportion of intestinal-type based on Lauren classification [77.1% (27/35) vs. 42.5% (214/504), χ(2)=14.553, P<0.001], and higher proportion of pathologic stage III [65.7% (23/35) vs. 27.6% (139/504), χ(2)=25.653, P<0.001]. The 3-year DFS of patients with NED and those without NED was 48.9% (95% CI: 33.8%-70.8%) and 37.4% (95% CI: 32.9%-42.5%) respectively, and no significant difference was found (P=0.44). The 3-year OS was 56.1% (95% CI: 39.9%-79.1%) and 64.3% (95% CI: 59.3%-69.7%) respectively, and no significant difference was found as well (P=0.32). Univariate and multivariate analyses showed that NED was not an independent risk factor for DFS and OS (all P>0.05). Sensitivity analysis showed that there was no significant difference in DFS and OS between the two groups after propensity score matching. Conclusion: Compared with patients without NED, patients with NED were older at onset, had a higher proportion of proximal gastrectomy, intestinal-type, and later diagnostic stage, but the survival prognosis had no significant difference with that of patients without NED.

Abstract
Temporomandibular joint (TMJ), a site that is often impacted by osteoarthritis (OA), is biomechanically linked with dental occlusion. Tissue responses in TMJ condyle to biomechanical stimulation could be investigated by intervention of the dental occlusion in animals. Unilateral anterior crossbite, an experimental malocclusion, has been demonstrated to induce TMJ-OA lesions, showing primarily as enhanced cartilage calcification and subchondral cortical bone formation at the osteochondral interface, causing the osteochondral interface thickening and stiffening. The changed interface would worsen the local biomechanical environment. At the cartilage side, the matrix degenerates. In the case of insufficient restoration of the matrix, the cells in the deep zone flow into the ones undergoing autophagy, apoptosis, and terminal differentiation while the cells in the superficial zone are promoted to differentiate to supply the loss of the deep zone cells. At the meantime, the bone marrow stromal cells are stimulated to bone formation in the subchondral cortical region which is uncoupled with the sites of the osteoclast-mediated resorption process that is predominantly observed at the subchondral trabecular bone region. Overall, the thickening and stiffening osteochondral interface, due greatly to the enhanced endochondral ossification in deep zone cartilage, should be a central pathological process that links with cartilage decay and subchondral bone remodelling in OA joints. The residual chondrocytes locating in the cartilage superficial zone have the progenitor-like qualities that can proliferate, and also differentiate into the deep zone chondrocytes, thus should be critical in progression and rehabilitation of TMJ-OA.

Abstract
OBJECTIVE Increasing evidence has shown that autophagy related proteins and hypoxia-inducible factor-1α (HIF-1α) are both involved in the malignant progress of nasopharyngeal carcinoma (NPC), and HIF-1α plays an emerging role in the chemosensitivity of NPC cells. However, it is still unknown whether autophagy related proteins are associated with HIF-1α in regulating the chemosensitivity of NPC cells. MATERIALS AND METHODS Quantitative Real-time PCR (qPCR) was applied to determine mRNA levels of HIF-1α and the autophagy related proteins, such as ATG3, ATG4B, ATG5, Beclin1, ATG7, ATG10, ATG12 and ATG16L1. Western blot was applied to determine protein levels of HIF-1α, ATG4B and cleaved Caspase-3. Cell viability and death were investigated by cell counting kit-8 and trypan blue exclusion assay. In addition, Caspase-3 activity was detected to reflect apoptosis. Furthermore, Luciferase reporter assay was applied to explore the mechanism by which HIF-1α transcriptionally upregulated ATG4B expression. RESULTS Our study reveals that HIF-1α increased ATG4B expression in NPC cells, and in turn upregulated the cisplatin (DDP)-induced protective autophagy, resulting in enhanced killing effect of DDP to NPC cells. In mechanism, reporter assay showed that HIF-1α upregulated ATG4B expression by activating its gene promoter region. The binding site (-225 to -216) was required for HIF-1α-induced increase of ATG4B gene promoter activity. CONCLUSIONS These results indicate that HIF-1α elevates ATG4B via promoting its transcription, which alleviates the sensitivity of DDP in NPC cells through enhancing protective autophagy, suggesting that ATG4B, upregulated by HIF-1α, may be a novel target for DDP sensitization in the treatment of NPC in clinic.

Abstract
OBJECTIVE The involvement of long non-coding RNA (LncRNAs) in HCC development has been widely recognized in recent decades. LncRNA small nucleolar RNA host gene 5 (SNHG5) has been identified to be implicated in the development of many tumors, and this study aimed to explore the role of SNHG5 in HCC tumorigenesis. PATIENTS AND METHODS The expression levels of SNHG5, miR-363-3p, and Ring Finger Protein 38 (RNF38) were measured by using quantitative Real Time-Polymerase Chain Reaction (qRT-PCR) or Western blot assay, respectively. Cell proliferation was analyzed by MTT assay. Flow cytometry was used to investigate cell apoptosis. Cell migration and invasion abilities were detected by transwell assay. The relationship among SNHG5, miR-363-3p, and RNF38 was confirmed using bioinformatics analysis and Luciferase reporter assay. RESULTS The expression of SNHG5 and RNF38 was elevated in HCC tissues and cell lines, and highly expressed SNHG5 and RNF38 could induce apoptosis and repress proliferation, migration, as well as invasion in HCC cells. Further investigations showed that SNHG5 might act as a competing endogenous RNA of miR-26a-5p and thereby cause the derepression of the downstream target RNF38. Moreover, rescue experiments indicated that SNHG5 silence inhibited the progression of HCC cells by regulating miR-363-3p, and the facilitated effects of RNF38 in the progression of HCC cells were regulated by miR-363-3p. CONCLUSIONS LncRNA SNHG5 may promote human HCC progression by regulating the miR-363-3p/RNF38 axis, providing a novel insight into the pathogenesis of HCC and therapeutic strategy for HCC treatment.

Abstract
BACKGROUND Heat shock protein 60 (Hsp60) play important roles in protecting testicular development and production of sperms. This study was conducted to investigate Hsp60 gene expression and localization in testicular development to ascertain its influence on infertility and in different tissues of the male cattle-yak and yak. A total of 54 cattle (24 cattle-yak and 30 yak) were examined. MATERIALS AND METHODS Hsp60 mRNA of cattle-yak was cloned first and amino acid variations were found leading to differences at protein spatial structure compare with the yak. Real-time quantitative PCR (RT-qPCR) analysis revealed that Hsp60 mRNAs expression were different in cattle-yak and yak. RESULTS The results showed disparity in Hsp60 expression among different tissues and in different developmental stages of the testis. High Hsp60 expression was observed in juvenile and adult testicles. Moreover, Hsp60 expression in cattle-yak was significantly higher than yak (p < 0.01). The location of Hsp60 in tissue and testis was detected by immunohistochemistry (IHC) and immunofluorescence (IF). The results demonstrated that Hsp60 proteins located in epithelial cells, spermatocytes, sperm cells and mesenchymal cells. CONCLUSIONS The Hsp60 proteins are expressed in different tissues, and the highest expression level was observed in the testis of the cattle-yak, which suggests that infertility of cattle-yak have some correlation with up-regulation of Hsp60.

Abstract
OBJECTIVE To explore the effect of parathyroid hormone (PTH) on the expression of Jagged1 in the rabbit tibial fracture healing, and its function and mechanism in this process via the Notch signaling pathway. MATERIALS AND METHODS A total of 60 New Zealand white rabbits were randomly divided into control group (n=30) and experimental group (n=30). Then, a rabbit tibial fracture model was established. After surgery, the rabbits in experimental group were given 10 μg/kg PTH (1-34) once a day for 5 days a week, while those in control group were given an equal volume of normal saline. Six rabbits were randomly selected from each group at 1, 2, 3, 4, and 6 weeks after surgery to collect right tibia specimens. Next, X-ray examination, bone mineral density (BMD) test, histological detection, and serum biochemical test were performed. Additionally, the messenger ribonucleic acid (mRNA) expression levels of Notch1 and Jagged1 in the Notch signaling pathway were measured via polymerase chain reaction (PCR) assay. Their protein levels were detected through Western blotting analysis. RESULTS The healing and BMD in experimental group were better than those in control group since cortical and medullary bridging was observed in the rabbits of experimental group at the 6th week after surgery. Plasma level of alkaline phosphatase (ALP), P content, and the product of Ca and P significantly increased (p<0.05) in experimental group. The pathological morphology of the calluses stained with hematoxylin-eosin (HE) in experimental group was overtly superior to that in control group. The PCR results revealed that both mRNA and protein levels of Notch1 and Jagged1 were lower in control group than those in experimental group (p<0.05). CONCLUSIONS PTH (1-34) promotes the rabbit tibial fracture healing by regulating Jagged1 ligand molecules in the Notch signaling pathway.

Abstract
The interfacial Dzyaloshinskii-Moriya interaction (i-DMI) has been exploited in as-made symmetrical Au/[Fe/Au]n structures. By tailoring the chirality of the i-DMI at the Au/Fe interface, an overall enhancement of the i-DMI can be obtained in such a symmetrical structure. Furthermore, the tunability of the i-DMI was realized by changing the stacking number n. Compared to the top of Fe, a large tensile stress at the bottom of Fe due to lattice mismatch was responsible for the chirality change in the sub/Au/Fe system. Layer-resolved DMI calculations revealed that the sign of the spin-orbit coupling (SOC) energy was changed for Au near the interface of Au/Fe under tensile stress, subsequently reversing the chirality of the i-DMI from left-handed to right-handed. Our findings provide a simplest way to tune the i-DMI in a multilayer system, further benefiting the application of skyrmion-based devices.

Abstract
BACKGROUND Sarcopenia is associated with adverse outcomes in cancer, chemotherapy, solid organ transplants, intensive care and medical patients. It has also been proven to increase perioperative mortality, hospital length of stay and complications in patients of various age groups. However, a limited number of studies have examined the association of post-surgical outcomes and sarcopenia inclusively in patients aged 65 years and older. OBJECTIVE This scoping review aimed to examine the relationship between adverse post-surgical outcomes and sarcopenia in patients aged 65 years and older. METHODOLOGY EMBASE and Medline databases were searched for sarcopenia, perioperative period and post-surgical outcomes. The articles were screened based on exclusion and inclusion criteria and were reviewed systematically as per the Joanna Briggs Institute (JBI) Methodology for Scoping Reviews. RESULTS After duplicates removal and application of the inclusion and exclusion criteria, eight articles were included for this study from a total of nine hundred initially identified articles. All studies defined sarcopenia as low muscle mass but did not include physical function or muscle strength as the parameter of sarcopenia. Low muscle mass was associated with higher mortality in emergency surgeries, reduced long term survival in open elective surgeries, and increased length of hospital stay in endoscopic surgeries. CONCLUSION The current review suggests that low muscle mass is associated with higher mortality and various adverse post-surgical outcomes in the elderly. It remains to be determined if applying the definition of sarcopenia as per the international consensus/guidelines will affect the association of adverse post-surgical outcomes and sarcopenia.

Abstract
Freshness is an important index to determine the quality deterioration (protein degradation and changes in appearance) of chilled chicken meat and is a primary consideration of consumers. Adenosine monophosphate deaminase 1 (AMPD1) catalyzes the deamination of adenosine monophosphate to inosine monophosphate in skeletal muscle and is the rate-limiting step in the purine nucleotide cycle. Inosine monophosphate is regarded as an important indicator of meat freshness in chicken. This study investigated the association of polymorphisms in the chicken AMPD1 promoter region with meat freshness during freezing storage. An SNP (c. -905G>A) was found to be associated with the freshness (K-value) of chicken breast meat. Chickens with the AA genotype had significantly lower K-values than those with GG and AG genotypes (P < 0.01). Individuals with the AA genotype also had higher breast meat AMPD1 mRNA levels than did those with the GG and AG genotypes (P < 0.01, P < 0.05). A luciferase assay revealed that genotype AA had greater transcriptional activity than genotype GG. Transcription factor binding site analysis identified distinct putative transcription factor binding sites in the two alleles of mutation site c. -905. In summary, we identified an SNP (c. -905G>A) in the promoter region of the AMPD1 gene that may modulate the binding affinity of different transcription factors to control AMPD1 expression and affect the freshness K-value of chicken meat.

Abstract
BACKGROUND Primary analysis of the phase III trial BG01-1323L demonstrated that utidelone plus capecitabine significantly improved progression-free survival (PFS) and overall response rate (ORR) versus capecitabine alone in heavily-pretreated patients with metastatic breast cancer (MBC). Here, we report the final overall survival (OS) analysis and updates of other endpoints. PATIENTS AND METHODS In total, 405 patients were randomised 2:1 to receive utidelone (30 mg/m2 IV daily, days 1-5, over 90 min) plus capecitabine (1000 mg/m2 orally b.i.d., days 1-14) or capecitabine alone (1250 mg/m2 orally b.i.d., days 1-14) every 21 days. The secondary endpoint, OS, was estimated using the Kaplan-Meier product-limit approach at a two-sided alpha level of 0.05 after the prespecified 310 death events had been reached. Exploratory analyses of the primary endpoint, PFS, and the secondary endpoint, ORR, were also done. Safety was analysed in patients who had at least one dose of study drug. RESULTS At the final OS analysis, the median duration of follow-up was 19.6 months in the utidelone plus capecitabine group and 15.4 months in the capecitabine alone group. In the intention-to-treat population, 313 deaths had occurred at data cut-off, 203 of 270 patients in the combination group and 110 of 135 in the monotherapy group. Median OS in the combination group was 19.8 months compared with 16.0 months in the monotherapy group [hazard ratio (HR) = 0.75, 95% confidence intervals (CI) 0.59-0.94, P = 0.0142]. The updated analysis of PFS and ORR showed that the combination therapy remained superior to monotherapy. Safety results were similar to those previously reported with respect to incidence, severity and specificity. No late-emerging toxicities or new safety concerns occurred. CONCLUSIONS For heavily-pretreated, anthracycline- and taxane-resistant MBC patients, utidelone plus capecitabine significantly improved OS versus capecitabine alone. These results support the use of utidelone plus capecitabine as a novel therapeutic regimen for patients with MBC.

Abstract
Abstract
Background
Peripheral artery disease (PAD) is prevalent and substantially contributes to cardiovascular mortality particularly in the elderly, although the pathophysiological impact of PAD on heart itself still needs further investigation. In theory, PAD can increase pulse wave reflection which is an important determinant of subendocardial viability ratio (SEVR), a valuable estimate of myocardial perfusion as indicated by previous invasive studies. Thus, we hypothesize that PAD impairs myocardial perfusion through increasing pulse wave reflection. In this study, we aim to test this hypothesis in a large cohort from the Northern Shanghai Study.
Methods
A total of 2947 community-dwelling elderly Chinese (43.6% male, mean age: 71.3±5.9 years) were recruited. Ankle-brachial index were measured with the VP1000 device and used to diagnose PAD. Pulse wave reflection was estimated as aortic augmentation pressure (AP). Aortic BP, AP and SEVR were assessed by radial applanation tonometry. Multiple linear regression with SEVR and AP as dependent variable and PAD as independent variable, meanwhile adjusted for other covariates, were performed, respectively.
Results
375 (12.7%) participants presented PAD. Compared to subjects without PAD, those with PAD showed significantly lower SEVR (126 vs. 132, P<0.001) but higher AP (19 vs. 17 mmHg, P<0.001). Multiple regression analysis revealed that both SEVR (regression coefficient [B] = −1.69, P=0.04, R2=0.61) and AP (B=1.19, P=0.04, R2=0.56) significantly associated with PAD, respectively. However, the association between SEVR and PAD was abolished when further adjusted for AP (B=−0.49, P=0.52). Similar results were obtained when inter-leg systolic BP difference was used to diagnose PAD.
Conclusions
PAD significantly and independently associates with myocardial perfusion; moreover, this association is mediated by increased pulse wave reflection. These findings provide a new dimension for understanding the pathophysiological mechanisms of cardiac damage of PAD.

Abstract
OBJECTIVE Osteoporosis (OP) has a high incidence and can be found in multiple age groups. The bone marrow mesenchymal stem cells (BMSCs) have the potential for self-renewal and multi-directional differentiation, which are often used for investigating the differentiation function of osteoporosis bone marrow mesenchymal stem cells. γ-glutamyl carboxylase (GGCX) is a carboxylase-related carboxylase and was observed to be abnormally expressed in osteoarthritis. However, the role and related mechanisms of GGCX in OP have not been fully elucidated. This work aimed to evaluate the effect of GGCX on the differentiation function of BMSCs. PATIENTS AND METHODS Sprague-Dawley rats were randomly divided into the OP group prepared by ovariectomy and sham group. GGCX expression was tested by enzyme-linked immunosorbent assay (ELISA). BMSCs were isolated from OP rats and transfected with pcDNA-GGCX plasmids. BMSC proliferation was detected by tetrazolium salt colorimetry (MTT) assay. The osteogenic and adipogenic differentiation of BMSCs was analyzed by alizarin red staining and oil red O staining. The ALP activity was determined by alkaline phosphatase (ALP) activity colorimetric assay. Real time-PCR was used to test the expressions of osteogenesis-related genes RUNX2 and OPN mRNA. Western blot was adopted to assess the TGFβ/smad signaling pathway activity. RESULTS GGCX expression was significantly decreased in the serum of OP rats compared with the sham group (p < 0.05). The transfection of pcDNA-GGCX plasmid significantly promoted BMSC cell proliferation, increased calcified nodule formation, inhibited adipogenic differentiation, enhanced ALP activity, elevated RUNX2, and OPN mRNA expressions, and upregulated TGFβ1, Smad2, and Smad7 expressions (p < 0.05). CONCLUSIONS GGCX secretion is reduced in osteoporosis. GGCX can regulate osteoporosis via promoting the TGFβ/smad signaling pathway, facilitating BMSCs osteogenic differentiation, and inhibiting BMSCs adipogenic differentiation.

Abstract
MDAP-2 is a new AMP with high inhibitory activity on Salmonella gallinarum, which may be developed as an antimicrobial agent in the agricultural industry and food preservation. To investigate the underlying the action mechanism of MDAP-2 on Salmonella gallinarum, impacts of MDAP-2 on the growth curve and bacterial morphology of Salmonella gallinarum were studied. iTRAQ-based proteomics analysis was also performed on proteins extracted from treated and untreated Salmonella gallinarum cells. The differentially expressed proteins were then analyzed using the KEGG and GO databases. Finally, the function of some differentially expressed proteins was verified. The results showed that 150 proteins (41 up-regulated and 109 down-regulated) were found differentially expressed (fold > 1.8, p⟨0.05). The results indi- cate that MDAP-2 kills Salmonella gallinarum mainly through two mechanisms: (i) direct inhibi- tion of cell wall/ membrane/ envelope biogenesis, energy production/ conversion, carbohydrate transport/ metabolism, and DNA transcription/ translation through regulation of special protein levels; (ii) indirect effects on the same pathway through the accumulation of Reactive oxygen species (O2 ▪-, H2O2 and OH▪-).

Abstract
1. Muchuan black-bone chicken is well known in China for its meat quality and medicinal properties; however, its egg-laying performance is not ideal. To better understand the molecular mechanisms of black-boned chicken egg-laying, high-throughput RNA sequencing was performed to compare differences in the pituitary transcriptome between three high-rate (group H) and three low-rate (group L) egg production chickens. 2. In total, 171 differentially expressed genes (DEGs) were identified between the two groups, of which 113 were upregulated and 58 were downregulated in group L. Some of these genes are known to be related to hormone secretion or the regulation of reproductive processes; these include prolactin-releasing hormone (PRLH), distal-less homeobox 6 (DLX6), interferon regulatory factor 4 (IRF4), and cilia and flagella associated protein 69 (CFAP69). Notably, expression pattern analysis indicated that both PRLH and DLX6 may influence egg-laying performance. 3. The dataset provided a foundation for discovering important genes and pathways involved in the chicken egg-laying process, and may help to improve understanding of the molecular mechanisms of chicken reproduction.

Abstract
Background The outbreak of Corona Virus Disease-2019 (COVID-19) has posed unprecedented pressure and threats to healthcare workers in Wuhan and the entire country. Aims To assess the effect of the COVID-19 outbreak on the sleep quality of healthcare workers in a children’s healthcare centre in Wuhan. Methods A cross-sectional, anonymized, self-reported questionnaire survey was conducted at the Children’s Healthcare Centre of Renmin Hospital, Wuhan University, Wuhan, China. The questionnaire consisted of three parts, including socio-demographic characteristics and COVID-19 epidemic-related factors, the Pittsburgh sleep quality index (PSQI), and Zung’s self-rating anxiety scale (SAS) and self-rating depression scale (SDS). Results In total, 47 out of 123 (38%) participants with PSQI scores > 7 were identified as having sleep disturbance. A logistic regression analysis showed that sleep disturbance was independently associated with being an only child (adjusted odds ratio (OR) and 95% confidence interval (CI) 3.40 (1.21–9.57), P < 0.05), exposure to COVID-19 patients (adjusted OR and 95% CI 2.97 (1.08–8.18), P < 0.05) and depression (adjusted OR and 95% CI 2.83 (1.10–7.27), P < 0.05). Conclusions We observed that, during the outbreak of COVID-19, sleep disturbance was highly prevalent among paediatric healthcare workers, and sleep disturbance was independently associated with being an only child, exposure to COVID-19 patients and depression. Therefore, more mental health services are required for front-line paediatric healthcare workers in Wuhan.

Abstract
1. Melanin content is considered an important indicator of meat quality in black-boned chickens, which have a high market value. To understand the complex physiological processes underlying muscle melanogenesis in this chicken, differentially expressed miRNAs (DEMs) were detected between black muscle (BM) and white muscle (WM) of chickens using high-throughput sequencing technology. Six small RNA libraries were constructed, and more than 16.75 million clean reads were obtained for each library. 2. A total of 582 known miRNAs and 65 novel miRNAs were identified from the six chicken sequence libraries. A total of 19 DEMs were identified between the two groups, of which nine were upregulated and 10 were downregulated. Furthermore, the DEMs were predicted to target 572 genes. 3. Certain DEMs (such as miR-204, miR-133b, and miR-12 229-3p) and their target genes may play an important role in muscle melanogenesis of chickens. These findings provide a foundation for clarifying the miRNA regulatory mechanisms involved in muscle pigmentation in avian species.

Abstract
Quantitative structure-property relationship (QSPR) models were developed for predicting the pungency of a set of capsaicinoids. Multiple linear regression (MLR) coupled with topological substructural molecular descriptor (TOPS-MODE) approach was used. The best MLR model based on only five orthogonalized TOPS-MODE variables allowed us to obtain a coefficient of determination of 0.954 on the training set. The predictive power of the model was validated through a test set and several external validation parameters. This showed that the TOPS-MODE descriptors weighted by bond dipole moments, van der Waals atomic radii, and the total solute hydrogen bond basicity affected pungency. The contributions of certain bonds and fragments to pungency were used to understand the pungency mechanism of capsaicinoids. The selected model can more accurately predict pungency of capsaicinoids compared than those found in the literature, and especially bring insights into the structural features and chemical factors related to pungency.

Abstract
Among the family of mycotoxins of deoxynivalenol (DON) detected in nature, high proportions of 15-acetyldeoxynivalenol (15ADON) co-occur with the prototype DON and increase the combined exposure and synergistic health risks. The current study aimed to explore the mechanisms underlying the toxicity of 15ADON and compare them with those of DON. As the natural flavonoid compound quercetin (QUE) possesses antioxidant properties, we also aimed to determine the antioxidant effects of QUE on the tested mycotoxins. First, the global metabolomics approach was applied and showed that the metabolites produced from 15ADON or DON were almost identical, while QUE reversed the changes in the levels of key metabolites. Specifically, both DON and 15ADON activated the cell apoptosis pathway mediated by p38 and JNK, but inhibited the cell survival pathway mediated by ERK1/2 in GES-1 cells. Simultaneously, 15ADON induced FOXO3a nuclear translocation, similar to the results described for DON in our recent report. Furthermore, the addition of QUE appeared to counteract the detrimental effects of 15ADON and DON. We observed the effects of QUE treatment on mutant yeast strains with defects in their antioxidant system. More interestingly, QUE also substantially restored the increased ROS levels and the inhibited the growth rate following exposure to the mycotoxins DON and 15ADON. The data reported here support the hypothesis that QUE rescues the toxic effects of DON or 15ADON due to the similar mechanisms of DON and 15ADON toxicity.

Abstract
The lateral arm flap (LAF) may offer an alternative option for oral cavity repair. Twenty-five Chinese patients with oral cavity defects were reconstructed with a LAF. The anatomical characteristics of the flap, the donor site complications, and the functional and aesthetic assessments of recipient site were reviewed. The overall flap survival was 96.0% (24/25patients). The average pedicle length was 7.07±1.09cm when it was cut off at the insert of the deltoid, with an average arterial diameter of 1.30±0.37mm and vein diameter of 2.06±0.48mm. The average flap length was 7.06±1.01cm, and the average flap breadth was 5.28±0.66cm, with the average flap size ranging from 18 to 42cm2. One to three reliable perforators supplied the flap, with the proximal, middle, and distal perforators being located at 9.9±1.1cm, 8.6±1.4cm, and 5.7±1.2cm from the lateral epicondyle, respectively. The donor defect was closed primarily and healed uneventfully. A longitudinal scar was the most common morbidity of the donor site. The function and shape of the reconstructed tissues were well restored. The LAF provides a reliable choice for reconstructing medium-sized oral cavity defects, with minimal donor-site morbidity and ideally functional and aesthetic rehabilitation of the recipient site.

Abstract
UNLABELLED This study evaluated the fragility fracture risk of Taiwanese postmenopausal women with osteopenia. With the incorporation of FRAX and hybrid intervention threshold (HIT), 25% of the participants had high fracture risk. We suggest intervention for fragility fracture for postmenopausal women should be guided by FRAX and HIT instead of bone mineral density alone. INTRODUCTION To explore the risk of fragility fracture in Taiwanese postmenopausal women with osteopenia using the hybrid intervention threshold (HIT) and Fracture Risk Assessment tool (FRAX). METHODS The Taiwan Osteoporosis Association (TOA) conducted a nationwide bone mineral density (BMD) survey between 2008 and 2011 using a bus equipped with a dual-energy X-ray absorptiometry (DXA) machine. All participants completed a structured questionnaire, which included the elements in the FRAX. Based on the results, the group made up of postmenopausal women with osteopenia was identified. In order to explore the risk of fragility fracture by HIT and FRAX among Taiwan postmenopausal women with osteopenia, the 10-year probability of fracture (FRAX score) and individual intervention threshold (IIT) in this group were calculated. If the FRAX score of a participant was higher than or equal to the IIT or fixed intervention threshold (FIT), the participant was considered as above the HIT (HIT could be reached by being over a threshold at either major osteoporotic fracture or hip fracture) and categorized as having a high FRAX fracture risk. RESULTS A total of 13,068 postmenopausal women were enrolled in the program. A total of 5743 (43.9%) participants had osteopenia, of which 1434 (25.0%) had high FRAX fracture risk. CONCLUSIONS One quarter of Taiwanese postmenopausal women with osteopenia had high fragility fracture risk evaluated by FRAX and HIT. Due to the poor sensitivity of BMD for fragility fracture, we suggest that intervention for fragility fracture for postmenopausal women should also be guided by FRAX and HIT instead of BMD alone.

Abstract
The aim of this study was to investigate the correlation between the maxillectomy defect, T stage, and prognosis of patients with maxillary squamous cell carcinoma (SCC). The Brown classification system was used to appraise the maxillectomy defects due to maxillary SCC. The clinical data of 137 patients with maxillary SCC during the period 2000-2010 were reviewed; 105 patients were followed up. Preoperative T stage and postoperative maxillectomy class were recorded. The relationship between the maxillectomy defect class and T stage of maxillary SCC was analysed. Correlations between the maxillectomy defect class, local recurrence rate, and survival rate were assessed using IBM SPSS Statistics v19.0. The most common maxillectomy defect class was IIb (54.7%, 75/137). The maxillectomy defect class was significantly associated with the T stage (P < 0.001). Both T stage and the maxillectomy defect class were significantly associated with the survival rate of patients with maxillary SCC (both P< 0.001). In conclusion, the class of the maxillectomy defect was found to be associated with the T stage. Both of these were prognostic factors for patients with maxillary SCC. The class of the maxillectomy defect is suitable for clinical application in predicting the prognosis compared with T stage.

Abstract
The Intrauterine fetal development process is complicated and affected by many regulating factors such as maternal nutritional status, transcription factors and adipokines. Adipokines are kinds of active substances secreted by adipose tissue, including more than 50 kinds of molecules. To explore the correlation between calf birth weights and adipokines including adiponectin, leptin, visfatin, and IGF-1 in cows venous and venous cord blood. Fifty-four healthy multiparous Chinese Holstein cows were used; in which, cows with a calf weight less than 40 kg were included in group A (n=9); those with a calf weight between 40 kg~45 kg were included in group B (n=25) and ≥45 kg were included in group C (n=20), venous blood and cord venous blood was collected. An ELISA kit was used to evaluate the concentration of adiponectin, leptin, visfatin, and IGF-1, correlations between index-index and index-calf birth weight were analysed. In both cows venous and cord venous blood, adiponectin, leptin, visfatin, and IGF-1 levels were significantly correlated with each other (p⟨0.01), and levels of these adipokines in venous blood were significantly higher than cord venous blood (p⟨0.01). Adiponectin, leptin, visfatin, and IGF-1 in venous cord blood were positively correlated with calf birth weights, and significantly correlated with calf birth weights respectively (p⟨0.01). Our study showed that adiponectin, leptin, and IGF-1 were found in venous blood and cord venous blood, and adiponectin, leptin, and IGF-1 in venous and cord venous blood potentially inter-regulated each other; adiponectin, leptin, and IGF-1 in venous blood were not significantly correlated with calf birth weights, while adiponectin, leptin, visfatin, and IGF-1 in venous cord blood were significantly correlated with calf birth weights, respectively.

Abstract
BACKGROUND AND PURPOSE We analyzed the incidence and causes of oral anticoagulant (OAC) cessation and subsequent stroke after OAC withdrawal in a cohort of Korean stroke patients with atrial fibrillation. METHODS The Korean Atrial Fibrillation Evaluation Registry in Ischemic Stroke patients (K-ATTENTION) is a multicenter cohort study, merging stroke registries from 11 tertiary centers in Korea. The number of OAC interruption episodes and the reasons were reviewed from hospital records. Stroke after OAC withdrawal was defined when a patient experienced ischaemic stroke within 31 days after OAC withdrawal. Clinical variables were compared between patients who experienced stroke recurrence during OAC interruption and those who did not experience recurrence. RESULTS Among 3213 stroke patients with atrial fibrillation, a total of 329 episodes of OAC interruption were detected in 229 patients after index stroke (mean age 72.9 ± 8.3 years, 113 female patients). The most frequent reason for OAC withdrawal was poor compliance [103 episodes (31.3%)] followed by extracranial bleeding [96 episodes (29.2%)]. Stroke after OAC withdrawal was noted in 13 patients. Mean age, vascular risk factor profile and mean CHA2 DS2 -VASc score were not significantly different between patients with and without recurrent stroke. CONCLUSIONS A considerable number of stroke patients with atrial fibrillation experienced temporary interruption of OAC after index stroke, which was associated with stroke recurrence of 4.0 cases per 100 interruption episodes.
