Abstract
OBJECTIVE This study aims to explore the molecular mechanism of macrophages and γδ-T cells in the ZOL drug-induced osteonecrosis of jaws based on the IFN-γ involved osteoblast differentiation signaling pathway. RESULTS The number and apoptotic rate of CD11b+Gr1hi cells and γδ-T cells in the ONJ group were significantly higher. The TNF-α, IL-1β, IFN-γ, CCL3, CCL4, IL-12 and IL-13 levels were significantly higher in the ONJ group. The expression of CTSK and FGFR3 was lower in the ONJ group, but was higher in the NF-κB and ERBB2IP group. CONCLUSION The proliferation of macrophages and γδ-T cells promote the inflammation in ZOL-induced jaw necrosis. METHODS A total of 20 patients with osteonecrosis of the jaw from January 2016 to March 2018 were collected and assigned into the observation group, while 20 healthy subjects were assigned into the control group. Furthermore, 40 SD rats were selected and assigned into observation group, while 10 non-treatment SD rats were selected and assigned as controls. The distribution and proportion of CD11b+Gr1hi cells and γδ-T cells in the necrotic tissues of the jaw were analyzed. Then, the TNF-α, IL-1β, IFN-γ, CCL3, CCL4, IL-12 and IL-13 levels were measured. Afterwards, the expression of CTSK, FGFR3, NF-κB and ERBB2IP in the necrotic tissues of the jaw in the animal models were analyzed.

Abstract
Systemic lupus erythematosus (SLE) is a complex heterogenous autoimmune disease that can be challenging to diagnose. We previously identified the IFN-induced protein 44-like (IFI44L) methylation marker for SLE diagnosis, which can be detected by pyrosequencing. Although the previous technique has high sensitivity and specificity, it requires special equipment and high cost for detection. Here, we established a high-resolution melting-quantitative polymerase chain reaction (HRM-qPCR) assay to detect the methylation of IFI44L promoter for the diagnosis of SLE. The result was determined according to the standard melting curve of the methylation level of the IFI44L promoter region. The sensitivity was 88.571% and the specificity was 97.087%. The HRM-qPCR and pyrosequencing results presented good consistency when both methods were used to detect the methylation of the IFI44L promoter for SLE diagnosis. Furthermore, the HRM-qPCR method can be used to distinguish SLE from other autoimmune diseases, infectious diseases and virus-related cancers.

Abstract
Stress relief treatments were carried out separately with a pneumatic chipping hammer, ultrasonic peening treatment, and heat treatment for metal active-gas welding (MAG) welded joints of 2205 duplex stainless steel. The effects of these methods on the residual stress, microstructure, mechanical properties and corrosion resistance of welded joints were studied. Results show the stress state of the weld and the surrounding area was effectively improved by the pneumatic chipping hammer and ultrasonic peening treatment, and the residual stress field of the surface layer changed from tensile stress to compressive stress. On the contrary, low-temperature stress relieving annealing had no obvious effect on stress distribution. After the pneumatic chipping hammer and ultrasonic peening treatment, the welded joints were machined and hardened. Correspondingly, strength and hardness were improved. However, the heat treatment only led to a slight decrease in strength and hardness due to the static recovery of the welded joint structure. All stress relief methods effectively improved the corrosion resistance of welded joints, with the ultrasonic peening treatment giving the best performance.

Abstract
Atherosclerosis is the leading cause of morbidity and mortality worldwide. The underlying pathogenesis involves multiple metabolic disorders, endothelial dysfunction and a maladaptive immune response, and leads to chronic arterial wall inflammation. Numerous normal physiological activities exhibit daily rhythmicity, including energy metabolism, vascular function and inflammatory immunoreactions, and disrupted or misaligned circadian rhythms may promote the progression of atherosclerosis. However, the association between the circadian rhythm and atherosclerosis remains to be fully elucidated. In the present review, the effects of the circadian rhythm on atherosclerosis progression are discussed.

Abstract
Periodontitis is a chronic inflammatory disease that can destroy periodontal tissue. Guided tissue regeneration (GTR) is widely applied to treat periodontitis. However, the challenge is to develop a GTR membrane capable of simultaneously regenerating periodontal tissue and preventing epithelial downgrowth into the defect. Herein, blended hydrogels composed of polyvinyl alcohol (PVA) and fish collagen (Col) were prepared as GTR membranes. The morphology, Col release, and cellular behavior of the blended hydrogels were evaluated. The results showed that the surface porosity and Col release of the PVA/Col blended hydrogels were enhanced by increasing the Col concentration. The adhesion and proliferation of human periodontal ligament fibroblasts (HPDLFs) and human gingival fibroblasts (HGFs) on the PVA/Col blended hydrogels can be regulated by tuning the PVA/Col ratio. The PVA/Col (50:50) blended hydrogel exhibited the highest cell proliferation rate for HPDLFs with spread cell morphology; the lowest viability for HGFs was found on the PVA/Col (100:0) hydrogel. Thus, by controlling the ratio of PVA to Col, multifunctional PVA/Col blended hydrogels able to regulate the cellular behavior of HPDLFs and HGFs can be developed, demonstrating their potential as GTR membrances for guiding periodontal tissue regeneration.

Abstract
INTRODUCTION National Comprehensive Cancer Network has recommended cryoablation to replace the resection in the treatment of medically operable non-small cell lung cancer (NSCLC). Cryoablation also has been used for the advanced NSCLC in randomised controlled trials. However, they have not been systematically reviewed. Here, we provide a protocol to evaluate the effectiveness and safety of cryoablation in the treatment of advanced NSCLC. METHODS AND ANALYSES We will search PubMed, Embase, the Cochrane Library, Chinese Biomedical Database, China National Knowledge Infrastructure, Wanfang Database and Chinese Scientific Journal Database without language restrictions from inception until 1 February 2020. Trial registers (International Clinical Trials Registry platform, the US National Institutes of Health Ongoing Trials Register and the ISRCTN registry) and reference lists of retrieved articles will also be searched. Two reviewers will independently extract data on participants, interventions, comparisons, outcomes and assess the methodological quality by the Cochrane risk of bias tool. The strength of evidences will be evaluated according to the Grading of Recommendations Assessment, Development and Evaluation approach. Review Manager V.5.3 software will be used for data analyses. Meta-analyses will be performed if the data are sufficiently homogeneous. The primary outcomes will be objective response rate and overall survival. The secondary outcomes will be adverse effects, health-related quality of life, changes of immune indicators and surrogate outcomes (disease control rate, progression-free survival and survival rate). ETHICS AND DISSEMINATION Ethics approval is not required, as this study will not involve patients. The results of this study will be submitted to a peer-reviewed journal for publication, to inform both clinical practice and further research. PROSPERO REGISTRATION NUMBER CRD42019138660.

Abstract
Objective: To establish a clustered management plan for pulmonary care of massive burn casualties (hereinafter referred to as the clustered management plan for pulmonary care), and to explore its application effects. Methods: (1) A clustered care intervention group was established, including the medical and nursing staff from the Department of Burns and Plastic Surgery, Department of Respiratory Medicine, and Department of Infection Control at the Fourth Medical Center of PLA General Hospital (hereinafter referred to as our hospital). Four major links, including pulmonary care assessment, chest and lung physical therapy, artificial airway management, and specialized infection control were sorted out according to the key points and difficulties in pulmonary care for massive burn casualties. Evidence-based nursing methods were employed to retrieve articles related to the above-mentioned four links from PubMed, Chinese Journal Full-Text Database, VIP Database and Wanfang Data using terms of " mass burn, respiratory management and airway management" and terms of ",," , and the clustered management plan for pulmonary care was established based on reading and discussion in combination with clinical practice and experience. (2) In this non-randomized controlled study, the clustered management plan for pulmonary care was applied to 73 massive burn patients (48 males and 25 females, aged 32 (25, 38) years) who were admitted to our hospital from January 2016 to December 2019 and met the inclusion criteria, and they were included into the clustered care group; 43 massive burn patients (25 males and 18 females, aged 35 (17, 45) years) who were admitted to our hospital from January 2013 to December 2015, received routine care and met the inclusion criteria were retrospectively included into routine care group. The pulmonary infection rate and mortality of patients in the two groups were recorded during the hospital stay. Data were statistically analyzed with chi-square test, Mann-Whitney U test, and independent sample t test. Results: (1) The clustered management plan for pulmonary care included a total of 12 specific measures covering four aspects of pulmonary care. The contents in pulmonary care assessment clearly stated to include the previous medical history, history of injury, respiratory status, hoarseness, pulmonary auscultation, etc. Chest and lung physical therapy included how to guide patients to effectively cough and do pursed lip breathing and abdominal breathing exercise, etc. Artificial airway management specified the preparation for the establishment of artificial airway at clinical reception, the observation index and frequency after tracheotomy, the method of humidification, the method and frequency of sputum suction, and the management of mechanical ventilation, etc. Specialized infection control required to strengthen hand hygiene and ventilator management. (2) The pulmonary infection rate and mortality of patients in the clustered care group were 2.74% (2/73) and 4.11% (3/73), respectively, significantly lower than 25.58% (11/43) and 18.60% (8/43) in routine care group (χ(2)=11.986, 5.043, P<0.05 or P<0.01). Conclusions: The clustered management plan for pulmonary care developed for massive burn casualties focuses on the major links and key points. The measures are systemic and comprehensive, simple but precise, and highly operable, covering the entire process of massive burn care, hereby reducing the pulmonary infection rate significantly and improving the success rate of treatment.

Abstract
BACKGROUND Body mass index (BMI) has been widely used as a prognostic indicator. The association between preoperative BMI and postoperative morbidity in patients with hilar cholangiocarcinoma (HCCA) has not been proved. This study aimed to identify the association between preoperative BMI and postoperative morbidity following radical resection of HCCA. METHODS Patients were divided into three groups according to preoperative BMI: low BMI (≤18.4 kg/m2 ), normal BMI (18.4-24.9 kg/m2 ), and high BMI (≥24.9 kg/m2 ). Baseline characteristics, operative variables, postoperative 30-day mortality, and morbidity were compared. Risk factors associated with postoperative morbidity were assessed using univariable and multivariable logistic analyses. RESULTS Among 260 patients, 183 (70.4%) had normal BMI, 32 (12.3%) had low BMI, and 45 (17.3%) had high BMI. Compared to the patients with normal-BMI, both low and high BMI patients exhibited a significantly higher postoperative morbidity (87.5% and 82.2% vs 63.9%, P = .019 and P = .025, respectively). Additionally, the multivariable analysis revealed that both low and high BMI patients remained independently associated with an increased risk of postoperative morbidity. (OR: 3.707, 95% CI: 1.080-12.725, P = .037; and OR: 2.858, 95% CI: 1.167-7.002, P = .022, respectively). CONCLUSION BMI is an independent risk factor for higher postoperative morbidity in patients who undergo surgical treatment of hilar cholangiocarcinoma.

Abstract
BACKGROUND Chemotherapy is the main therapy for stage IIIB/IV non-small cell lung cancer (NSCLC). However, the 5-year survival rate is 6%. Cancer Green Therapy is a novel therapy in China, which refers to cryoablation combined with traditional Chinese medicine (TCM) formula. Our previous retrospective analysis showed that patients with NSCLC had longer survival time and better quality of life after receiving cryoablation combined with TCM formula, compared with patients who received chemotherapy alone. METHODS This study is a multicenter, randomized, controlled clinical study. The experiment will be carried out in 6 hospitals at the same time, and a total of 450 cases of participants will be randomly assigned to the experimental group and the control group (n = 225). The experimental group will be given cryoablation and 28-days TCM formula, and the control group will be given 4 cycles chemotherapy. After 30 months of follow-up, the efficacy and safety of cryoablation combines with TCM formula in patients with stage IIIB/IV NSCLC will be observed. The primary outcome is overall survival. The secondary outcomes include progression-free survival, objective response rate, and quality of life. We will also conduct a safety evaluation of the treatment at the end of the trial. DISCUSSION This multicenter, randomized, controlled clinical study not only provides data on the efficacy and safety of cryoablation combined with TCM formula, but also provides a novel treatment strategy for clinicians and advanced NSCLC patients.

Abstract
Karst aquifer systems are tended to be polluted compared to other types of aquifers because pollutants are able to enter aquifers through developed conduit systems. To identify the effects of hydrogeochemical conditions on the distribution of pesticides in a karst river system in Kaiyang, southwest China, a typical pollution mode combining intermittent infiltration with intrusion was constructed. Twelve aqueous samples were collected along the karst river, and a total of 24 pesticides were detected. The results showed that the pesticide ubiquity and the dominant organophosphate (40%) and organonitrogen pesticides (49%) were both observed. Based on the spatial distribution, the attenuation of pesticides was found in the underground conduit and surface river. The wastewater treatment plant and the rural dump were the two important point sources releasing pesticides. In addition, ten core pesticides were identified by clustering analysis and regional characteristics of three types of pesticides in Songnen Plain, North China Plain, and Southwest karst areas were also summarized. With correlation analysis between pesticides and environmental factors, the significant correlations of pesticides with ammonium ion and dissolved oxygen were found, which indicated that rapid developing urbanization and long-term agricultural practices could remarkably affect the spatial distribution of pesticides. The calculation of ecological risk quotients showed that organophosphate pesticides had the highest risk to invertebrate, followed by organonitrogen pesticides, and finally organochlorine pesticides. Invertebrates were the most vulnerable aquatic organisms. These findings fill a gap in the multiple pesticides' pollution in the karst areas of China. Graphical abstract.

Abstract
The cereal formula powder, Zhengda Jingshan (ZDJS), comprises dietary fiber, multivitamins, fine protein, and various cereal ingredients. The present study evaluated the effects of ZDJS on glucose metabolism and explored the corresponding mechanisms in terms of modulating gut microbiota and the fecal metabolome. Type 2 diabetic db/db mice were given ZDJS (1 g/kg) orally twice daily for 55 days, after which glucose metabolism, inflammation, gut microbiota, and fecal metabolomics were assayed. Repeated administration of ZDJS was associated with a trend toward decreasing fasting blood glucose and a 0.12% decrease in hemoglobin A1c (HbA1c), as well as statistically significant increases in the insulin sensitivity index and decreases in serum levels of tumor necrosis factor (TNF-α) and ileum expression of mucin-2. ZDJS also ameliorated the compensatory enlargement of islets and decreased the ratio of the α-cell area to total islet area; however, this amelioration of impaired oral glucose tolerance became less pronounced as treatment continued. In addition, ZDJS remarkably decreased the abundance of phylum Proteobacteria and the phylum ratio of Firmicutes to Bacteroidetes, as well as altered the fecal metabolic profile. Taken together, our findings demonstrate that ZDJS improved glucose metabolism and reduced inflammation in type 2 diabetic db/db mice, which may be associated with a reshaping of the gut microbiome and fecal metabolome in db/db mice. Thus, our study suggests that ZDJS may represent a complementary therapy for patients with type 2 diabetes.

Abstract
Triple-negative breast cancer (TNBC) cannot be treated with current hormonal therapies and has a higher risk of relapse than other breast cancers. To identify potential therapeutic targets for TNBC, we conducted microRNA sequencing (RNA-Seq) in human TNBC specimens and tumor-matched controls. We found that growth differentiation factor-10 (GDF10), a member of the TGF-β superfamily, was downregulated in tumor samples. Further analysis of GDF10 expression in a larger set of clinical TNBC samples using qPCR confirmed its downregulation and association with parameters of disease severity. Using human-derived TNBC cell lines, we carried out GDF10 under- and overexpression experiments, which showed that GDF10 loss promoted cell proliferation and invasion. By contrast, overexpression of GDF10 inhibited proliferation, invasion, and epithelial mesenchymal transition (EMT) via upregulation of Smad7 and E-Cadherin, downregulation of p-Smad2 and N-Cadherin, and reduction of nuclear Smad4 expression. In addition, overexpression of GDF10 reduced tumor burden and induced apoptosis in a TNBC xenograft mouse model. These findings indicate that GDF10 acts as a tumor suppressor in mammary epithelial cells that limits proliferation and suppresses EMT. Efforts aimed at restoring GDF10 expression may thus bring a long-sought therapeutic alternative in the treatment of patients with TNBC.

Abstract
The ubiquitous second messenger c-di-GMP is involved in regulation of multiple biological functions including the important extracellular matrix exopolysaccharides (EPS). But how c-di-GMP metabolic proteins influence EPS and their enzymatic properties are not fully understood. Here we showed that deletion of proE, which encodes a protein with GGDEF-EAL hybrid domains, significantly increased the transcriptional expression of the genes encoding EPS production in Pseudomonas aeruginosa PAO1 and changed the bacterial colony morphology. Our data showed that ProE is a very active phosphodiesterase (PDE), with a high enzyme activity in degradation of c-di-GMP. Interestingly, the optimal activity of ProE was found in the presence of Co2+, unlike other PDEs that commonly rely on Mg2+ or Mn2+ for best performance. Furthermore, we identified three widely conserved novel residues that are critical for the function of ProE through site-directed mutagenesis. Subsequent study showed that ProE, together with other three key PDEs, i.e., RbdA, BifA, and DipA regulate the EPS production in P. aeruginosa PAO1. Moreover, by using the GFP-fusion approach, we observed that these four EPS associated-PDEs showed a polar localization pattern in general. Taken together, our data unveil the molecular mechanisms of ProE in regulation of EPS production, and provide a new insight on its enzymatic properties in degradation of c-di-GMP.

Abstract
Lévy walks (LWs) are spatiotemporally coupled random-walk processes describing superdiffusive heat conduction in solids, propagation of light in disordered optical materials, motion of molecular motors in living cells, or motion of animals, humans, robots, and viruses. We here investigate a key feature of LWs-their response to an external harmonic potential. In this generic setting for confined motion we demonstrate that LWs equilibrate exponentially and may assume a bimodal stationary distribution. We also show that the stationary distribution has a horizontal slope next to a reflecting boundary placed at the origin, in contrast to correlated superdiffusive processes. Our results generalize LWs to confining forces and settle some longstanding puzzles around LWs.

Abstract
BACKGROUND The mechanism of pyruvate kinase M2 (PKM2)-mediated inflammatory signalling in macrophages when plaques rupture and the impact of hyperglycaemia on the signalling are unclear. The present study aimed to explore the impact of hyperglycaemia on PKM2-mediated NOD-like receptor family pyrin domain containing 3 (NLRP3) inflammasome/stress granule signalling in macrophages and its correlation with plaque vulnerability in vivo and in vitro. METHODS From July to December 2019, 80 patients with coronary heart disease (CHD) were divided into acute ST-segment elevation myocardial infarction (STEMI) (n = 57) (DM-STEMI, n = 21; non-DM-STEMI, n = 36) and stable CHD (SCHD) groups (n = 23). Circulating mononuclear cells were isolated. The value of peak troponin I (TnI), the Global Registry of Acute Coronary Events (GRACE) risk score, and the expression levels of the related markers were quantified and compared. In vitro studies on the THP-1 cells were also performed. RESULTS The DM-STEMI group had a higher value of peak TnI and a higher GRACE risk score than the non-DM-STEMI group (p < 0.05). The highest expression levels of PKM2, NLRP3, interleukin (IL)-1β, and IL-18 and the lowest expression level of GTPase activating protein (SH3 domain)-binding protein 1 (G3BP1) (a stress granule marker protein) were observed in the DM-STEMI group, and they were followed by the non-DM-STEMI group and the SCHD group (p < 0.05). In vitro studies showed similar results and that TEPP-46 (a PKM2 activator) and 2-deoxy-d-glucose (a toxic glucose analogue) reversed the hyperglycaemia-induced increase in the NLRP3 inflammasome and decrease in G3BP1 expression. CONCLUSION Hyperglycaemia might increase the activation of PKM2-mediated NLRP3 inflammasome/stress granule signalling and increase plaque vulnerability, associating it with worse prognosis. PKM2 may be a novel prognostic indicator and a new target for the treatment of patients with CHD and DM.

Abstract
AIMS To explore a prokaryotic species-specific DNA marker, 16S-23S rRNA gene internal transcribed spacer (ITS) sequence for identification and classification of Vibrio. METHODS AND RESULTS Five hundred and seventy four ITS sequences from 60 Vibrio strains were collected, then the primary and secondary structures of ITS sequence were analysed. The ITS was divided into several subunits, and the species-specificity of these subunits were evaluated by blast. The variable subunit of ITS showed high species-specificity. A protocol to identify a Vibrio species based on ITS analysis was developed and verified. Both the specificity and sensitivity were 100%. The phylogeny analysis of Vibrio based on ITS showed that ITS devised a better classification than 16S rDNA. Finally, an identification method of Vibrio based on ITS sequencing in food samples was developed and evaluated. The results of ITS sequencing were (100%) consistent with the results identified by ISO standard. CONCLUSIONS Vibrio could be accurately identified at the species level by using the ITS sequences. SIGNIFICANCE AND IMPACT OF THE STUDY The present study suggests that the ITS can be considered as a significant DNA marker for identification and classification of Vibrio species, and it posed a new path to screen the Vibrio in food sample.

Abstract
Diabetic retinopathy (DR) is a vision-threatening complication of diabetes mellitus characterized by chronic retinal microvascular inflammation. The involvement of CD4+ T cells in retinal vascular inflammation has been considered, but the specific subset and mechanism of T cell-mediated response during the process remains unclear. Here, we aim to investigate the potential role of follicular helper T (Tfh) cells, a newly identified subset of CD4+ T cells in retinal vascular inflammation in DR. Methods: Patients with DR were enrolled and the PD-1+CXCR5+CD4+ Tfh cells were detected in the peripheral blood by flow cytometry. The streptozotocin (STZ)-induced DR model and oxygen-induced retinopathy (OIR) model were established, and 79-6, an inhibitor of Bcl-6, was injected intraperitoneally to suppress Tfh cells. The Tfh cells-related genes were investigated in the spleen, lymph nodes, and retina of mice by flow cytometry, immunofluorescence, and qPCR. Results: The Tfh cells expanded in the circulation of patients with DR and also increased in circulation, lymph nodes and retinal tissues from the STZ-induced DR mice and OIR mice. Notably, inhibition of Bcl-6, a critical transcription factor for Tfh cells development, prevented upregulation of Tfh cells and its typical IL-21 cytokine, and ameliorated vascular leakage in DR mice or retinal angiogenesis in OIR mice, indicating that Bcl-6-directed Tfh cells could promote vascular inflammation and angiogenesis. Conclusions: Our results suggested that excessive Bcl-6-directed Tfh cells represent an unrecognized feature of DR and be responsible for the retinal vascular inflammation and angiogenesis, providing opportunities for new therapeutic approaches to DR.

Abstract
Polarization lidar has been widely used in recent decades to observe the vertical structures of aerosols and clouds in the atmosphere. We developed a dual-polarization lidar system that can detect polarization measurements simultaneously at 355 nm and 532 nm. Dust events and haze episodes over northern China in 2014 were observed by the developed lidar. The results showed that the dust-dominated aerosol depolarization ratios at 532 nm were larger than those at 355 nm, but those of the air pollutants were smaller, indicating that this tool could provide a more accurate classification of aerosols. Moreover, we found a good relationship between the absorption coefficient of aerosols and the ratio of depolarization ratios at 532 nm and 355 nm for dust aerosols. Our results imply that aerosol absorption from polarization measurements may be determined by lidar at the ultraviolet and visible wavelengths.

Abstract
OBJECTIVE This study aimed to investigate whether long-chain non-coding ANCR is involved in the progression of non-small cell LCa (NSCLC) and its possible molecular mechanisms. PATIENTS AND METHODS Quantitative Real Time-Polymerase Chain Reaction (qRT-PCR) was applied to examine ANCR expression in 48 cases of NSCLC and adjacent normal tissues. In addition, ANCR level in patients of different tumor staging was analyzed. The Kaplan-Meier method was applied to analyze the interplay between ANCR expression and the prognosis of patients with NSCLC. Subsequently, qRT-PCR was performed to detect ANCR level in LCa cell lines. After knocking down ANCR in A549 cells, ANCR and E-Ca mRNA expression were examined by qRT-PCR, while the expression levels of epithelial-mesenchymal transition (EMT)-related proteins were detected by Western blot. At the same time, cell viability and migration ability were analyzed through cell counting kit-8 (CCK-8) and cell wound healing assay, respectively. RNA immunoprecipitation (RIP) test was performed to verify the binding of ANCR to EZH2. After knocking down EZH2 in A549 cells, E-Ca messenger ribonucleic acid (mRNA) expression was detected. Additionally, Chromatin immunoprecipitation (ChIP) assay was performed to detect the binding of EZH2 to the E-Ca promoter region. When E-Ca and ANCR were simultaneously knocked down in A549 cells, Western blot investigation was performed to examine the expression of EMT-related proteins, while CCK-8 and wound healing assays were applied to figure out the changes in cell viability and cell migration capacity. RESULTS ANCR level was conspicuously higher in NSCLC tissues than that in normal tissues, and that in T3 and T4 tumors was also higher than that in T1 and T2. Meanwhile, ANCR expression in the tissues of patients with lymph node metastasis was conspicuously higher than those without metastasis. Survival analysis revealed that the overall survival of patients with NSCLC with high expression of ANCR was conspicuously lower than patients with low expression of ANCR. The qRT-PCR study verified that ANCR was highly expressed in the LCa cell line A549. After knocking down ANCR in A549 cells, ANCR and E-Ca mRNA levels were found conspicuously decreased, and so were the expression levels of EMT-related proteins, as well as the cell viability and migration ability. The RIP assay result indicated that ANCR can indeed bind to EZH2. E-Ca mRNA expression was elevated after the knockdown of EZH2 in A549 cells. In addition, the result of CHIP test demonstrated that EZH2 could combine with E-Ca. Simultaneous down-regulation of ANCR and E-Ca in A549 cells could reverse the influence of knocking down ANCR alone on cell viability and migration ability. CONCLUSIONS Long-chain non-coding RNA ANCR was highly expressed in NSCLC tissues and could enhance the viability and malignancy of NSCLC cells by inhibiting the expression of E-Ca, thereby promoting the progression of NSCLC.

Abstract
Monitoring surgeon workload during robot-assisted surgery can guide allocation of task demands, adapt system interfaces, and assess the robotic system's usability. Current practices for measuring cognitive load primarily rely on questionnaires that are subjective and disrupt surgical workflow. To address this limitation, a computational framework is demonstrated to predict user workload during telerobotic surgery. This framework leverages wireless sensors to monitor surgeons’ cognitive load and predict their cognitive states. Continuous data across multiple physiological modalities (e.g., heart rate variability, electrodermal, and electroencephalogram activity) were simultaneously recorded for twelve surgeons performing surgical skills tasks on the validated da Vinci Skills Simulator. These surgical tasks varied in difficulty levels, e.g., requiring varying visual processing demand and degree of fine motor control. Collected multimodal physiological signals were fused using independent component analysis, and the predicted results were compared to the ground-truth workload level. Results compared performance of different classifiers, sensor fusion schemes, and physiological modality (i.e., prediction with single vs. multiple modalities). It was found that our multisensor approach outperformed individual signals and can correctly predict cognitive workload levels 83.2% of the time during basic and complex surgical skills tasks.

Abstract
Understanding the thermal transport mechanisms in amorphous organic materials is of great importance to solve hot-spot issues in organic-electronics nanodevices. Here we studied thermal transport in two popular molecular electronic materials, N,N-dicarbazolyl-3,5-benzene (mCP) and N,N'-diphenyl-N,N'-di(3-methylphenyl)-(1,1'-biphenyl)-4,4'diamine (TPD), in the amorphous state by molecular dynamics simulations. We found that due to the softness of organic materials, the low thermal conductivity of both systems can be greatly enhanced under pressure. Notably, in such systems, the convective term of heat flux provides an important contribution to thermal transport as it cross-correlates with the Virial term in the Green-Kubo formula. Mode diffusivity calculations reveal that low-frequency modes can contribute significantly to thermal transport in both mCP and TPD. By increasing the pressure, the sound velocity and relaxation time of such low-frequency modes can be enhanced, and a part of these modes converts from diffusons to propagons. The cooperation of these three effects is responsible for the strong pressure dependence of thermal transport in amorphous organic systems. Molecular pair heat flux calculations demonstrate that heat transfer mainly happens between pairs of molecules with distances below 1.4 nm. This work paves the way for the optimization of thermal transport in amorphous organic materials widely used in opto-electronics, e.g. as OLED and OPV.

Abstract
Multi-wavelength (mw) Bragg coherent X-ray diffraction imaging (BCDI) is demonstrated on a single Au particle. The multi-wavelength Bragg diffraction patterns are inverted using conventional phase-retrieval algorithms where the dilation of the effective pixel size of a pixelated 2D detector caused by the variation of the X-ray beam energy is mitigated by interpolating the raw data. The reconstructed Bragg electron density and phase field are in excellent agreement with the results obtained from conventional rocking scans of the same particle. Voxel sizes of about 63 nm3 are obtained for reconstructions from both approaches. Phase shifts as small as 0.41 rad, which correspond to displacements of 14 pm and translate into strain resolution better than 10−4 in the Au particle, are resolved. The displacement field changes shape during the experiment, which is well reproduced by finite element method simulations considering an inhomogeneous strained carbon layer deposited on the Au particle over the course of the measurements. These experiments thus demonstrate the very high sensitivity of BCDI and mw-BCDI to strain induced by contaminations. Furthermore, mw-BCDI offers new opportunities for in situ and operando 3D strain imaging in complex sample environments.

Abstract
Flaxseed cake (FSC) is a potential alternative feed source in poultry. However, cyanogenetic glycosides limit its widespread use in feed. In this study, we optimized the parameters of fermentation by Aspergillus niger and Candida utilis and compared the growth performance, serum lipid parameters, and organ indexes of Cherry Valley duckling feed with unfermented FSC (UFSC) or fermented FSC (FFSC). A total of 420 one-day-old male Cherry Valley ducklings were randomly assigned into a 1 plus 2 × 3 factorial design including 2 different FSC resources (UFSC and FFSC) at 3 levels (50, 100, or 150 g/kg) for 3 wk. Each treatment group included 6 pens with 10 ducklings per pen. The hydrocyanic acid (HCN) level was reduced under the following conditions: 1:0.8 FSC:water (w:v), inoculum ratio of 1 mL:1 mL, 30°C, and 60 h. FFSC had higher crude protein (CP) and calcium (Ca) levels and lower HCN levels compared with UFSC (P < 0.05). There was no interactive effect between FSC sources and levels on growth performance. Final body weight (FBW), average daily feed intake (ADFI), and average daily gain (ADG) in UFSC groups and ADFI in FFSC groups decreased linearly with increasing FSC levels (P < 0.01). There were no differences in FBW, ADG, or feed:gain ratio (F/G) among FFSC groups, and all 7 FSC groups had no differences in the F/G ratio (P > 0.05). Dietary FSC supplementation decreased triglyceride (TG) (P < 0.01), total cholesterol (TC) (P < 0.01), high-density lipoprotein (HDL) (P = 0.01), and low-density lipoprotein (LDL) (P < 0.01). No interactive effect between FSC levels and sources was observed for serum TG, TC, HDL, or LDL. Ducklings fed FFSC had lower TG (P < 0.01), TC (P = 0.05), and LDL (P < 0.01) levels compared with ducklings fed UFSC. The 150 g/kg FFSC group had the lowest TG, TC, HDL, and LDL levels among all 7 groups. Flaxseed cake supplementation decreased the relative weight of the left breast, but FFSC increased the relative weight of the gizzard compared with UFSC. In conclusion, fermentation could increase the nutritional value and usage of FSC in ducklings.

Abstract
INTRODUCTION Whole brain radiotherapy (WBRT) has been the mainstay treatment of brain metastases (BM) in non-small cell lung cancer (NSCLC) patients for years. Temozolomide (TMZ) could penetrate the blood-brain barrier and some studies showed that TMZ plus MBRT may improve clinical effectiveness. This meta-analysis is aim to evaluate the clinical effectiveness and safety of TMZ plus MBRT in the NSCLC patients with BM. METHODS AND ANALYSIS We systematically searched databases including PubMed, EMBASE, Cochrane Central Register of Controlled Trials, and four Chinese databases (Chinese Biomedical Database, China National Knowledge Infrastructure, Wanfang Database and Chinese Scientific Journal Database) without language restrictions from inception until July 26, 2019. Randomized controlled trials (RCTs) which compared TMZ plus WBRT with single WBRT in the advanced NSCLC patients with BM were included. The outcomes analysis reported objective response rate (ORR), disease control rate (DCR), overall survival (OS), progression-free survival (PFS), quality of life (QOL), and adverse effects. Two reviewers will independently extract data from the selected studies and assess the quality of studies. Statistical analyses will be performed using Review manager 5.3 software. Random-effects or fixed models were used to estimate pooled hazard ratio and relative risk. RESULTS This systemic review and meta-analysis will evaluate the effects of TMZ plus MBRT in the NSCLC patients with BM in RCTs. CONCLUSION Our study will provide evidence to judge if TMZ plus MBRT are effective treatment for NSCLC patients with BM.

Abstract
Quorum sensing (QS) is a cell–cell communication mechanism among bacterial populations that is regulated through gene expression in response to cell density. The pathogenicity of Xanthomonas campestris pv. campestris (Xcc) is modulated by the diffusible signal factor (DSF)-mediated QS system. DSF is widely conserved in a variety of gram-negative bacterial pathogens. In this study, DSF-degrading bacteria and their enzymes were thoroughly explored as a biocontrol agent against Xcc. The results indicated that a novel DSF-degrading bacterium, Acinetobacter lactucae QL-1, effectively attenuated Xcc virulence through quorum quenching. Lab-based experiments indicated that plants inoculated with QL-1 and Xcc had less tissue decay than those inoculated with Xcc alone. Co-inoculation of strains Xcc and QL-1 significantly reduced the incidence and severity of disease in plants. Similarly, the application of crude enzymes of strain QL-1 substantially reduced the disease severity caused by Xcc. The results showed that strain QL-1 and its enzymes possess promising potential, which could be further investigated to better protect plants from DSF-dependent pathogens.

Abstract
Berberine (BBR), a small alkaloid, is used as a hypoglycemic agent in China. Stachyose (Sta), a Rehmannia glutinosa oligosaccharide, acts as a prebiotic. This study aimed to evaluate whether BBR combined with Sta produced better glycometabolism than BBR alone, and explored the effects on gut microbiota and metabolomics. Type‐2 diabetic db/db mice were administered BBR (100 mg/kg), Sta (200 mg/kg), or both by gavage once daily. Glucose metabolism, the balance of α‐ and β‐cells, and mucin‐2 expression were ameliorated by combined treatment of BBR and Sta, with stronger effects than upon treatment with BBR alone. The microbial diversity and richness were altered after combined treatment and after treatment with BBR alone. The abundance of Akkermansia muciniphila was increased by combined treatment compared to treatment with BBR alone, while the levels of the metabolite all‐trans‐heptaprenyl diphosphate were decreased and the levels of fumaric acid were increased, which both showed a strong correlation with A. muciniphila. In summary, BBR combined with Sta produced better glycometabolism than BBR alone through modulating gut microbiota and fecal metabolomics, and may aid in the development of a novel pharmaceutical strategy for treating Type 2 diabetes mellitus.

Abstract
Objective: To analyze the association between circular RNAs expression in serum and gastric cancer and evaluate the potential of the related markers in early diagnosis of gastric cancer. Methods: Forty eight gastric cancer cases in Linqu County People's Hospital were selected as case group, and 48 controls matched by age and sex were randomly selected in the gastric cancer screening cohort during the same period. The expression levels of hsa_circ_002059, hsa_circ_0000096 and hsa_circ_0001895 were detected by quantitative real-time PCR. The results were compared between case group and control group. Results: The positive expression rates of hsa_circ_002059, hsa_circ_0000096 and hsa_circ_0001895 were 70.8%, 47.9%, 75.0% in case group, slightly higher than those in control group (58.3%, 31.3%, 60.4%), although P values were all more than 0.05. The expression level medians of the 3 candidate circRNAs expression levels were 1.60% (0-5.64%), 0 (0-0.61%), 0.91% (0.06%-1.88%) in case group, while 0.05% (0-6.07%), 0 (0-0.34%), 0.42% (0-1.39%) in control group, respectively. Conditional logistic regression analysis showed that the association strength of high expressions of 3 candidate circRNAs with gastric cancer showed an increase trend, but the differences had no significance after adjusted by Helicobacter pylori infection, smoking and drinking status (all P>0.05). Further analysis by combining the 3 candidate circRNAs showed the increased strength of association between circRNAs and gastric cancer with the elevated number of positive circRNAs in serum (trend test P=0.040) compared with circRNAs negative persons. Conclusion: Our study preliminarily suggested that the expression of hsa_circ_002059, hsa_circ_0000096 and hsa_circ_0001895 in serum might be correlated with gastric cancer.

Abstract
Background: Non-functional pituitary adenoma (NFPA) is a common tumor that occurs in the pituitary gland, and generally without any symptoms at its early stage and without clinical elevation of hormones, which is commonly diagnosed when it grows up to compress its surrounding tissues and organs. Currently, the pathogenesis of NFPA has not been clarified yet. It is necessary to investigate molecular alterations in NFPA, and identify reliable biomarkers and drug therapeutic targets for effective treatments. Methods: Tandem mass tags (TMT)-based quantitative proteomics was used to identify and quantify proteins in NFPAs. GO and KEGG enrichment analyses were used to analyze the identified proteins. Differentially expressed genes (DEGs) between NFPA and control tissues were obtained from GEO datasets. These two sets of protein and gene data were analyzed to obtain overlapped molecules (genes; proteins), followed by further GO and KEGG pathway analyses of these overlapped molecules, and molecular network analysis to obtain the hub molecules with Cytoscape. Two hub molecules (SRC and AKT1) were verified with Western blotting. Results: Totally 6076 proteins in NFPA tissues were identified, and 3598 DEGs between NFPA and control tissues were identified from GEO database. Overlapping analysis of 6076 proteins and 3598 DEGs obtained 1088 overlapped molecules (DEGs; proteins). KEGG pathway analysis of 6076 proteins obtained 114 statistically significant pathways, including endocytosis, and spliceosome signaling pathways. KEGG pathway analysis of 1088 overlapped molecules obtained 52 statistically significant pathways, including focal adhesion, cGMP-PKG pathway, and platelet activation signaling pathways. These pathways play important roles in cell energy supply, adhesion, and maintenance of the tumor microenvironment. According to the association degree in Cytoscape, ten hub molecules (DEGs; proteins) were identified, including GAPDH, ALB, ACACA, SRC, ENO2, CALM1, POTEE, HSPA8, DECR1, and AKT1. Western-blotting analysis confirmed the upregulated expressions of SRC and PTMScan experiment confirmed the increased levels of pAKT1, in NFPAs compared to controls. Conclusions: This study established the large-scale quantitative protein profiling of NFPA tissue proteome. It offers a basis for subsequent in-depth proteomics analysis of NFPAs, and insight into the molecular mechanism of NFPAs. It also provided the basic data to discover reliable biomarkers and therapeutic targets for NFPA patients.

Abstract
activin βA and βB from diploid and allotriploid crucian carp were cloned.The differential expression of activin βA and βB genes in female allotriploid and diploid red crucian carp Carassius auratus red var. were studied and found to be expressed in all the tested tissues; particularly, the expression of activin βA and βB was elevated in the ovaries of allotriploids and differential expression in pituitaries during the non-breeding season and the breeding season period. The immunohistochemistry indicated that the abnormal triploid ovaries were dominated by small oogonium-like cells with dense signals and that the elevated expression of activin βA and βB in the ovaries of allotriploids may be related to allotriploid sterility.

Abstract
Breast cancer (BC) leads to the highest mortality in women worldwide, characterized by inevitable proliferation and metastasis of BC cells. Mounting evidence confirm that lncRNAs play a significant role in the tumorigenesis and development of BC. lncRNA CERS6‐AS1 is a novel discovery, and its role and molecular mechanism in BC has not been studied. In this study, it was discovered that CERS6‐AS1 was overexpressed in BC tissues and cells. CERS6‐AS1 accelerated cell proliferation and suppressed cell apoptosis in BC. Moreover, molecular mechanism exploration uncovered that there was a positive association between CERS6 and CERS6‐AS1 (or IGF2BP3) expression in BC. Furthermore, IGF2BP3 serves as a RNA‐binding protein for CERS6‐AS1 and CERS6‐AS1 promoted CERS6 mRNA stability by binding to IGF2BP3. In the end, rescue experiments verified that overexpression of CERS6 rescues the inhibition of CERS6‐AS1 deficiency on BC progression in vitro and vivo. Taken together, these evidences suggested that CERS6‐AS1 promoted the progression of BC by binding to IGF2BP3 and thus enhancing the stability of CERS6 mRNA, providing a new underlying therapeutic target for BC to improve prognosis.

Abstract
AIMS To evaluate a novel tetrahydroisoquinoline derivative YR4-42 as a selective peroxisome proliferator-activated receptor γ (PPARγ) modulator (SPPARM) and explore its anti-diabetic effects in vitro and in vivo. MATERIALS AND METHODS Using two standard full PPARγ agonists rosiglitazone and pioglitazone as controls, the PPARγ binding affinity and transactivation action of YR4-42 were evaluated using biochemical and cell-based reporter gene assays. The capacity of YR4-42 to recruit coactivators of PPARγ was also assessed. The effects of YR4-42 on adipogenesis and glucose consumption and PPARγ Ser273 phosphorylation were investigated in 3T3-L1 adipocytes. The effects of YR4-42 and pioglitazone, serving as positive control, on glucose and lipids metabolism were investigated in high-fat diet-induced obese (DIO) C57BL/6J mice. The expression of PPARγ target genes involved in glucose and lipid metabolism was also assessed in vitro and in vivo. RESULTS In vitro biochemical and cell-based functional assays showed that YR4-42 has much weaker binding affinity, transactivation, and recruitment to PPARγ of the coactivators thyroid hormone receptor-associated protein complex 220 kDa component (TRAP220) and PPARγ coactivator 1-α (PGC1α) compared to full agonists. In 3 T3-L1 adipocytes, YR4-42 significantly improved glucose consumption without a lipogenesis effect, while blocking tumour necrosis factor α-mediated phosphorylation of PPARγ at Ser273, thereby upregulating the expression of the PPARγ Ser273 phosphorylation-dependent genes. Furthermore, in DIO mice, oral administration of YR4-42 ameliorated the hyperglycaemia, with a similar insulin sensitization effect to that of pioglitazone. Importantly, YR4-42 also improved hyperlipidaemia-associated hepatic steatosis without weight gain, which avoids a major side effect of pioglitazone. Thus, YR4-42 appeared to selectively modulate PPARγ responses. This finding was supported by the gene expression analysis, which showed that YR4-42 selectively targets PPARγ-regulated genes mapped to glucose and lipid metabolism in DIO mice. CONCLUSIONS We conclude that YR4-42 is a novel anti-diabetic drug candidate with significant advantages compared to standard PPARγ agonists. YR4-42 should be further investigated in preclinical and clinical studies.

Abstract
Background Bleeker’s yellow tail (Xenocypris davidi Bleeker, YT) and topmouth culter (Culter alburnus Basilewsky, TC) are both famous and important economic freshwater fish in China. YT, a kind of omnivorous fish, has strong resistance. TC, a kind of carnivorous fish, has high-quality meat but poor resistance. Distant hybridization can integrate the advantages of both parents. There has been no previous report regarding hybrid fish derived from female YT × male TC. It is expected that hybridization of these two kinds of fish will result in F1 hybrids with improved characteristics, such as faster growth rate, stronger resistance, and high-quality meat, which are of great significance in fish genetic breeding. Results In this study, we investigated the main biological characteristics of diploid hybrid fish derived from female YT × male TC. The hybrids had an intermediate number of upper lateral line scales between those for YT and TC. The hybrids were diploids with 48 chromosomes and had the same karyotype formula as their parents. The hybrids generated variations in 5S rDNA (designated class IV: 212 bp) and lost specific 5S rDNA derived from the maternal parent (designated class II: 221 bp), which might be related to hybridization. In terms of reproductive traits, all the tested female hybrids exhibited normal gonadal development, and the two-year-old F1 females produced mature eggs. However, all the tested testes of the male hybrids could not produce mature sperm. It is possible that the hybrid lineage will be established by back-crossing the fertile female hybrids and their parents. Conclusions Obtaining a fertile female hybrid fish made the creation of a new type of fish possible, which was significant in fish genetic breeding.

Abstract
AIM Acute coronary syndrome (ACS), a leading cause of morbidity and mortality worldwide, is among the most serious cardiovascular diseases. Circadian rhythms are present in almost all organisms. In clinical practice, we have found that ACS is closely related to these circadian rhythms. However, the relationship between circadian rhythms and plaque instability in ACS patients is incompletely understood. The aim of this study is to provide new insights into the relationship between circadian rhythms and plaque instability in ACS patients. METHODS We enrolled patients with ACS and individuals with normal coronary artery function in this study. The Athens Insomnia Scale (AIS), Pittsburgh Sleep Quality Index (PSQI), International Physical Activity Questionnaire (IPAQ) and Healthy Diet Score (HDS) were used to evaluate circadian rhythms. Furthermore, quantitative real-time polymerase chain reaction (qRT-PCR) was used to assess the mRNA expression levels of muscle aryl hydrocarbon receptor nuclear translocator-like protein 1 (Bmal1), circadian locomotor output cycles kaput (Clock), Cryptochrome1 (Cry1), Period2 (Per2), nuclear receptor subfamily 1, group D, member 1 (Rev-erbα), and matrix metalloproteinases MMP2 and MMP9. RESULTS AIS scores and PSQI scores were significantly higher in patients with ST segment elevation myocardial infarction (STEMI), non-ST segment elevation myocardial infarction (NSTEMI), and unstable angina pectoris (UA) than in the normal controls (NCs) (P < 0.05). The IPAQ scores of the NCs and patients with UA were significantly higher than in patients with STEMI and NSTEMI (P < 0.05). Notably higher HDS scores were recorded for the NCs compared to those of patients with UA, NSTEMI, and STEMI (P < 0.05). Consistent with these findings, compared with the NCs, the lowest levels of Bmal1, Clock, Cry1, Per2 and Rev-erbα mRNAs were detected in patients with STEMI, followed by patients with NSTEMI and then patients with UA (P < 0.05). Furthermore, the levels of MMP2 and MMP9 mRNA were significantly higher in the patients with STEMI, NSTEMI, and UA than those in the NCs (P < 0.05). In addition, we found that the levels of MMP mRNA negatively correlated with the levels of clock genes mRNAs (P < 0.05, respectively). CONCLUSIONS Based on our data, the circadian rhythms and clock genes are correlatively with the occurrence of ACS, and the expression levels of clock genes are negatively correlated with plaque stability in ACS patients.

Abstract
This article introduces the Turn-Taking Spiking Neural Network (TTSNet), which is a cognitive model to perform early turn-taking prediction about a human or agent’s intentions. The TTSNet framework relies on implicit and explicit multimodal communication cues (physical, neurological and physiological) to be able to predict when the turn-taking event will occur in a robust and unambiguous fashion. To test the theories proposed, the TTSNet framework was implemented on an assistant robotic nurse, which predicts surgeon’s turn-taking intentions and delivers surgical instruments accordingly. Experiments were conducted to evaluate TTSNet’s performance in early turn-taking prediction. It was found to reach an [Formula: see text] score of 0.683 given 10% of completed action, and an [Formula: see text] score of 0.852 at 50% and 0.894 at 100% of the completed action. This performance outperformed multiple state-of-the-art algorithms, and surpassed human performance when limited partial observation is given (<40%). Such early turn-taking prediction capability would allow robots to perform collaborative actions proactively, in order to facilitate collaboration and increase team efficiency.

Abstract
Nuclear import of proteins relies on nuclear import receptors called importins/karyopherins (Kaps), whose functions were reported in yeasts, fungi, plants, and animal cells, including cell cycle control, morphogenesis, stress sensing/response, and also fungal pathogenecity. However, limited is known about the physiological function and regulatory mechanism of protein import in the rice-blast fungus Magnaporthe oryzae. Here, we identified an ortholog of β-importin in M. oryzae encoded by an ortholog of KAP119 gene. Functional characterisation of this gene via reverse genetics revealed that it is required for vegetative growth, conidiation, melanin pigmentation, and pathogenicity of M. oryzae. The mokap119Δ mutant was also defective in formation of appressorium-like structure from hyphal tips. By affinity assay and liquid chromatography-tandem mass spectrometry, we identified potential MoKap119-interacting proteins and further verified that MoKap119 interacts with the cyclin-dependent kinase subunit MoCks1 and mediates its nuclear import. Transcriptional profiling indicated that MoKap119 may regulate transcription of infection-related genes via MoCks1 regulation of MoSom1. Overall, our findings provide a novel insight into the regulatory mechanism of M. oryzae pathogenesis likely by MoKap119-mediated nuclear import of the cyclin-dependent kinase subunit MoCks1.

Abstract
BACKGROUND Vascular network formation induced by angiogenesis plays an important role in many physiological and pathological processes. However, the role of blood flow and underlying mechanisms in vascular network formation, for example for the development of the caudal vein plexus (CVP), is poorly understood. OBJECTIVE The aim of this study was to explore the role of ERK5-klf2a-nos2b signaling in the CVP angiogenesis. METHOD AND RESULTS In this study on tnnt2a-MO injection and chemical blood flow modulator treatment in zebrafish embryos, we demonstrated that decreased blood flow disrupted CVP formation. The hemodynamic force was quantitatively analyzed. Furthermore, CVP angiogenesis in zebrafish embryos was inhibited by disruption of the blood flow downstream effectors ERK5, klf2a, and nos2b in response to treatment with the ERK5 specific inhibitor and to injection of klf2a-MO, nos2b-MO. Overexpression of klf2a mRNA or nos2b mRNA restored vascular defects in tnnt2a or klf2a morphants. The data suggest that flow-induced ERK5-klf2a-nos2b signaling is involved in CVP angiogenesis in zebrafish embryos. CONCLUSION We have demonstrated that blood flow is essential for vascular network formation, specifically for CVP angiogenesis in zebrafish. A novel genetic and mechanical mechanism was discovered in which ERK5 facilitates the integration of blood flow with the downstream klf2a-nos2b signaling for CVP angiogenesis.

Abstract
A variety of surface modification methods are applied to modify titanium implants to improve their biological activity. Micro-arc oxidation (MAO) can relatively simply and efficiently produce porous coatings with high bioactivity and bond strength on titanium surfaces. However, there is no conclusion about the effect of coatings with different pore sizes produced by MAO on bone marrow mesenchymal stem cells (BMSCs). To study the effect of different pore sizes on BMSCs, rat BMSCs were applied to detect the effect of different pore sizes prepared by MAO on cell adhesion and osteogenic differentiation. Three groups of coatings with different pore sizes were successfully prepared, and the pore size was within the range of 3-10 µm. Importantly, the expression of adhesion-related protein integrin β1 and osteogenic-related proteins OSX and ALP increased along with the increase in pore size. This study showed that the porous coating prepared by MAO promotes BMSCs adhesion and osteogenic differentiation. It reveals that the pore size is in the range of 3-10 µm and the larger pores are more beneficial for BMSCs adhesion and osteogenic differentiation. This study is instructive for optimizing the design of biomedical implant surfaces.
