Abstract
Glomerella leaf spot (GLS), caused by the fungus Colletotrichum fructicola, is considered one of the most destructive diseases affecting apples. The VQ-WRKY complex plays a crucial role in the response of plants to biotic stresses. However, our understanding of the defensive role of the VQ-WRKY complex on woody plants, particularly apples, under biotic stress, remains limited. In this study, we elucidated the molecular mechanisms underlying the defensive role of the apple MdVQ37-MdWRKY100 module in response to GLS infection. The overexpression of MdWRKY100 enhanced resistance to C. fructicola, whereas MdWRKY100 RNA interference in apple plants reduced resistance to C. fructicola by affecting salicylic acid (SA) content and the expression level of the CC-NBS-LRR resistance gene MdRPM1. DAP-seq, Y1H, EMSA, and RT-qPCR assays indicated that MdWRKY100 inhibited the expression of MdWRKY17, a positive regulatory factor gene of SA degradation, upregulated the expression of MdPAL1, a key enzyme gene of SA biosynthesis, and promoted MdRPM1 expression by directly binding to their promotors. Transient overexpression and silencing experiments showed that MdPAL1 and MdRPM1 positively regulated GLS resistance in apples. Furthermore, the overexpression of MdVQ37 increased the susceptibility to C. fructicola by reducing the SA content and expression level of MdRPM1. Additionally, MdVQ37 interacted with MdWRKY100, which repressed the transcriptional activity of MdWRKY100. In summary, these results revealed the molecular mechanism through which the apple MdVQ37-MdWRKY100 module responds to GLS infection by regulating SA content and MdRPM1 expression, providing novel insights into the involvement of the VQ-WRKY complex in plant pathogen defence responses.

Abstract
Peanut production is threatened by climate change. Damage to seedlings from low temperatures in early spring can limit yield. Plant adaptations to chilling stress remain unclear in peanut seedlings. It is essential to understand how peanut acquires chilling tolerance. We evaluated effects of chilling stress on growth and recovery of peanut seedlings. We compared and analysed biological characteristics, antioxidants, photosynthesis, biochemical and physiological responses, and nutrient absorption at varying levels of chilling. Compared with chilling-sensitive FH18, the reduced impact of chilling stress on chilling-tolerant NH5 was associated with reduced ROS accumulation, higher ascorbate peroxidase activity and soluble sugar content, lower soluble protein content, and smaller reductions in nutrient content during stress. After removal of chilling stress, FH18 had significant accumulation of O2 •- and H2O2, which decreased photosynthesis, nutrient absorption, and transport. ROS-scavenging reduced damage from chilling stress, allowed remobilization of nutrients, improved chilling tolerance, and restored plant functioning after chilling stress removal. These findings provide a reference for targeted research on peanut seedling tolerance to chilling and lay the foundation for bioinformatics-based research on peanut chilling tolerance mechanisms.

Abstract
OBJECTIVE Surgical treatment of unilateral Wilms tumor (WT) in children is controversial. In this study, we aimed to evaluate the survival and prognosis of radical nephrectomy (RN) and nephron-sparing surgery (NSS) in children with unilateral WT receiving adjuvant chemotherapy. PATIENTS AND METHODS Data on pediatric patients with WT were collected from the Surveillance, Epidemiology, and End Results (SEER) database from 2000 to 2019. Multivariate logistic regression was used to analyze factors influencing the choice of surgical strategy. Cox proportional hazard models were used to assess factors associated with overall survival. RESULTS We included 1,825 patients with unilateral WT (<14 years) who received adjuvant chemotherapy and surgery. Between 2000 and 2019, the percentage of patients treated with NSS increased from 4% in 2000 to 8% in 2019. There was no significant difference in 10-year overall survival between the two surgical strategies [NSS vs. RN, 93.26% (95% CI, 86.88%-100%) vs. 92.17% (95% CI, 90.75%-93.61%), p=0.98]. Patients with unilateral WTs ≤4 cm were more likely to be treated with NSS. There was no survival benefit for patients treated with RN compared with that for those treated with NSS (HR, 0.74; 95% CI, 0.29-1.86; p=0.5). CONCLUSIONS The use of NSS in children with unilateral WT has increased over the last two decades. Tumor size is an important influencing factor for the surgical application of NSS. Patients who underwent NSS had an equivalent OS compared with the overall group of patients with unilateral tumors who received RN.

Abstract
Developing efficient water-splitting electrocatalysts to accelerate the slow oxygen evolution reaction (OER) kinetics is urgently desired for hydrogen production. Herein, ultralow phosphorus (P)-doped NiFe LDH (NiFePx LDH) with mild compressive strain is synthesized as an efficient OER electrocatalyst. Remarkably, NiFePx LDH with the phosphorus mass ratio of 0.32 wt.% and compressive strain ratio of 2.53% (denoted as NiFeP0.32 LDH) exhibits extraordinary OER activity with an overpotential as low as 210 mV, which is superior to that of commercial IrO2 and other reported P-based OER electrocatalysts. Both experimental performance and density function theory (DFT) calculation demonstrate that the doping of P atoms can generate covalent Fe─P coordination bonds and lattice distortion, thus resulting in the consequent depletion of electrons around the Fe active center and the downward shift of the d-band center, which can lead to a weaker adsorption ability of * O intermediate to improve the catalytic performance of NiFeP0.32 LDH for OER. This work provides novel insights into the distinctive coordinated configuration of P in NiFePx LDH, which can result in superior catalytic performance for OER.

Abstract
Objective: To analyze the PET/CT imaging features of fluoride 18F-fluorodeoxyglucose (18F-FDG) in patients with various types of Parkinson's syndrome (PS), and to establish a "diagnostic tree" model of 18F-FDG PET/CT for PS. Methods: Data of patients with Parkinson's disease (PD), patients with multiple system atrophy cerebellar type (MSA-C), and patients with multiple system atrophy Parkinson's type (MSA-P)admitted to the Neurology Department of Huashan Hospital affiliated to Fudan University from January 2019 to December 2021. 18F-FDG PET/CT examination was conducted in all patients. Clinical and follow-up data was collected to determine clinical diagnosis. The specific patterns of brain glucose metabolism in patients with various types of Parkinsonism were observed and their utility in the differential diagnosis of the disease was analyzed. 18F-FDG PET/CT imaging"diagnostic tree"model was established and its value in the differential diagnosis of Parkinsonism was verified. Results: A total of 320 patients, 187 males and 133 females, aged (62±9) years, were enrolled in our study, including 80 PD, 90 PSP, 114 MSA-C and 36 MSA-P patients. The differential diagnostic features of cerebral glucose metabolism of Parkinsonism were as follows: the metabolism of putamen increased in PD patients, the metabolism of caudate nucleus, thalamus, midbrain, and frontal lobe decreased in PSP patients, the metabolism of cerebellum decreased in MSA-C patients, and the metabolism of putamen and cerebellum decreased in MSA-P patients. The sensitivity and specificity of the"diagnostic tree"model are 88.75% and 91.25% for PD diagnosis, 54.44% and 96.96% for PSP diagnosis, 87.72% and 86.41% for MSA-C diagnosis, and 55.56% and 91.55% for MSA-P diagnosis, respectively. It could correctly classify 75%(240/320) of patients. Conclusions: Characteristic metabolism patterns of brain in 18F-FDG PET/CT imaging is significant for the differential diagnosis of PD, PSP, MSA-C and MSA-P. The"diagnostic tree"model is valuable for clinical diagnosis.

Abstract
BACKGROUND Diabetic nephropathy (DN) is one of the complications of diabetes and has a high mortality, but its specific pathogenesis is not clear. In recent years, researches on the mechanism of circRNAs in DN have been proved a lot, whereas the functional mechanism of circ_0003928 in DN remains open and it must be investigated to value its important role in DN prevention. METHODS HK-2 cells were treated with high glucose (HG), normal glucose (NG) or Mannitol. Cell counting kit-8 (CCK8) and 5-ethynyl-2'-deoxyuridine (EdU) assays were performed to detect cell proliferation. Enzyme-linked immunosorbent assay (ELISA) was applied to analyze malondialdehyde (MDA) and superoxide dismutase 1 (SOD) levels. Flow cytometry and western blot were preformed to measure cell apoptosis. Real-time quantitative PCR (RT-qPCR) was used to test the levels of circ_0003928, miR-136-5p and progestin and adipoQ receptor family member 3 (PAQR3) mRNA. Western blot was executed to detect Bcl2 associated X (Bax), B cell leukemia/lymphoma 2 (Bcl2), smooth muscle (αSMA), apolipoprotein (C-IV) and PAQR3 levels. Luciferase reporter assay and RNA pull-down assay were used to analyze the target relationship between miR-136-5p and circ_0003928 or PAQR3. RESULTS Circ_0003928 and PAQR3 expression were up-regulated, whereas miR-136-5p was decreased in DN serum and HG-induced HK-2 cells. Circ_0003928 knockdown promoted cell proliferation, and inhibit cell apoptosis, oxidative stress, and fibrosis in HK-2 cells under HG condition. MiR-136-5p silencing overturned the protective effects of si-circ_0003928 on HG-induced HK-2 cells. MiR-136-5p was targeted by circ_0003928 and directly targeted PAQR3. Overexpression of PAQR3 counteracted the inhibitory functions of circ_0003928 knockdown or miR-136-5p overexpression on HG-induced HK-2 cell injury. CONCLUSION Circ_0003928 acted as a sponge of miR-136-5p to up-regulating PAQR3 expression, and then regulate the proliferation, oxidative stress, fibrosis and apoptosis in HG-induced HK-2 cells.

Abstract
Browning is a crucial factor affecting the quality of fresh-cut apples. A safe, simple, and effective method to inhibit browning is urgently needed in fresh-cut apple production. We carried out this study to explore the effect mechanism of exogenous selenium (Se) fertilizer on fresh-cut apple browning. During the development of apples, 0.75 kg/plant Se fertilizer was exerted on the 'Fuji' apple tree at the critical stage of the young fruit stage (late May), early fruit expansion stage (late June), and fruit expansion stage (late July), an equal amount of Se-free organic fertilizer was used as control. Polyphenol oxidase (PPO), peroxidase (POD), and phenylalanine ammonia-lyase (PAL) activities, phenolic and malondialdehyde (MDA) content, antioxidant enzymes activity, and DPPH free radical scavenging rate of the apple at different development stages were investigated. The highest Se accumulation efficiency was observed in apple fruit one month after applying Se fertilizer, which was 41.1%. Se-rich apples exhibited a more remarkable ability to resist browning than control after fresh-cut. The anti-browning effect of the fertilization group (M7) was the best, the PPO activity decreased to 0.5 × 103 U kg-1, and the browning index was 28.6. The total Se content (TSC) of 331.4 μg kg-1 DW and organic Se content (OSC) of 292.0 μg kg-1 DW were the highest in the apple samples, reached the classification standard of Se content in Se-rich food. The correlation analysis found that fresh-cut apple browning was closely related to antioxidant capacity and PPO activity. The stronger the antioxidant capacity of fresh-cut apples treated with Se fertilizer, the lower their browning degree. Therefore, exogenous Se can alleviate fresh-cut apples browning by improving antioxidant capacity and reducing PPO activity. Se-rich apples could increase the Se content of the human essential trace element and inhibit the browning of fresh-cut apples, which would become a new, safe and effective way to solve the fresh-cut apples browning.

Abstract
In order to determine the underlying mechanism of the senescence occurring in older apple trees, the effects of tree age on the community structure and dominant genus of endophytic rhizosphere bacteria in apple were investigated. The diversity and structure of the bacterial communities and corresponding changes in the dominant genera of endophytic rhizosphere bacteria of apple at different ages (2, 8, 16, 22 years) were compared based on 16S rRNA high-throughput sequencing technology. The results revealed that the longer the tree age, the less the number of ASV in the endophytic bacteria. Moreover, the number of ASV in the endophytic bacteria gradually decreased as the tree age increased, however no significant changes were observed in the alpha diversity. At the phyla level, the relative abundance of Actinobacteria increased, while that of Proteobateria decreased. At the genus level, the relative abundance of Mycobacterium, Chujaibacter, and other genera increased, while the relative abundance of Aquabacterium, Ralstonia, Streptomyces, Asticcacaulis, Hyphomicrobium, Pseudomonas, and Sphingomonas decreased. The reduced relative abundance of endophytic rhizosphere bacteria associated with plant growth and disease resistance may thus be the cause of tree senescence. This work acts as a reference to increases the understanding of plant-microbe interactions.

Abstract
The walnut is an important nut that has numerous uses worldwide. However, due to dwarf and close plantation methods as well as continuous cloudy or rainy days that occur during periods of walnut oil accumulation, the walnut fruit exhibits varying degrees of stress under low-light conditions. However, the effects of shade on metabolites and genes in walnut embryos remain unclear in the literature. The purpose of this study is to investigate the lipid biosynthesis process that occurs in walnut embryos under shade treatment via the use of metabolomics and transcriptomics analyses. The results indicate that the oil content decreases significantly under shaded conditions, while the protein content increases significantly. The expression levels of fatty acid desaturase 2 (FAD2) and stearoyl-ACP-desaturase (SAD) involved in the lipid biosynthesis mechanism were significantly reduced in the shaded group, which resulted in reductions in oleic (C18:1), linoleic (C18:2), and α-linolenic (C18:3) acids. The reduced oil content was consistent with the downregulation of genes associated with the lipid biosynthesis mechanism. In the amino acid biosynthesis process, the upregulated cysteine synthase (cscK) and anthranilate synthase beta subunit 2 (trpG) genes promoted the accumulation of L-aspartic acid and L-citrulline. The increase in protein content was consistent with the upregulation of genes related to amino acid biosynthesis. Thus, our study provides new insights into the regulatory mechanisms of shade underlying overall walnut fruit quality.

Abstract
Apple growth and yield are largely dependent on plant height and flowering characteristics. The BELL1-like homeobox (BLH) transcription factors regulate extensive plant biological processes. However, the BLH-mediated regulation of plant height and flowering in apple remains elusive. In the current study, 19 members of the MdBLH family were identified in the apple genome. Segmental duplication and purifying selection are the main reasons for the evolution of the MdBLH genes. A BLH1-like gene, MdBLH14, was isolated and functionally characterized. The MdBLH14 was preferentially expressed in flower buds, and downregulated during the floral induction period. The subcellular localization in tobacco leaves indicated that MdBLH14 is a nuclear protein. Overexpression of MdBLH14 in Arabidopsis led to a significant dwarfing and late-flowering phenotype by hindering active GA accumulation. Additionally, MdKNOX19, another member of the TALE superfamily, physically interacts with MdBLH14 and synergistically inhibits the expression of MdGA20ox3. This is the first report on the function of the MdBLH14 from apple, and its mechanism involving plant flower induction and growth. The data presented here provide a theoretical basis for genetically breeding new apple varieties.

Abstract
AT-hook motif nuclear localization (AHL) proteins play essential roles in various plant biological processes. Yet, a comprehensive understanding of AHL transcription factors in walnut (Juglans regia L.) is missing. In this study, 37 AHL gene family members were first identified in the walnut genome. Based on the evolutionary analysis, JrAHL genes were grouped into two clades, and their expansion may occur due to segmental duplication. The stress-responsive nature and driving of developmental activities of JrAHL genes were revealed by cis-acting elements and transcriptomic data, respectively. Tissue-specific expression analysis showed that JrAHLs had a profound transcription in flower and shoot tip, JrAHL2 in particular. Subcellular localization showed that JrAHL2 is anchored to the nucleus. Overexpression of JrAHL2 in Arabidopsis adversely affected hypocotyl elongation and delayed flowering. Our study, for the first time, presented a detailed analysis of JrAHL genes in walnut and provided theoretical knowledge for future genetic breeding programs.

Abstract
AIMS To compare the sensitivity, specificity, accuracy, and clinical usefulness of transcranial Doppler (TCD) ultrasound against computed tomography angiography (CTA) for the diagnosis of ischaemic cerebrovascular disease. METHODS A total of 1,183 sites (vascular segments) of 169 patients who had been diagnosed with cerebrovascular disease using digital subtraction angiography (DSA) were evaluated by CTA and TCD for the diagnosis of the arterial lesions. RESULTS Lesions were identified in 509 sites and 674 sites did not have lesions according to the DSA examination. Each individual site had higher sensitivity, specificity, and accuracy for TCD than those for CTA, respectively. For all sites, TCD had higher true-positive (p=0.0029) and -negative (p=0.0151) values and fewer false-positive and -negative (p<0.0001 for both) values than those of CTA. The sensitivity, specificity, and accuracy of CTA for all sites to detect lesions were 77%, 88%, and 84%, respectively. The same parameters for TCD were 94%, 97%, and 95%, respectively. The beneficial scores for CTA and TCD to detect lesions were 0-0.795 diagnostic confidence and 0-0.91 diagnostic confidence, respectively. Beneficial scores >0.795 and >0.91 indicated a risk of underdiagnosis of lesions at CTA and TCD, respectively. CONCLUSIONS Compared with DSA (reference standard) and CTA, the study underscores the use of TCD in cerebrovascular pathology.

Abstract
OBJECTIVE This study aims to investigate the correlations between gene alterations induced in Mdr2-knockout (Mdr2-/-) models and liver fibrosis. SUBJECTS AND METHODS The overlapping genes in Mdr2-/- models were determined and included in logistic regression analysis to identify potential candidates for predicting liver fibrosis. Correlations between the expression levels of the identified candidates and hepatic stellate cells (HSCs) were addressed. Functional enrichment of the identified candidates was also evaluated via bioinformatic analysis. RESULTS Twenty-two overlapping genes in the GSE4612, GSE8642 and GSE14539 datasets were identified. Univariate and multivariate analysis indicated that ELOVL fatty acid elongase 7 (ELOVL7) was significantly associated with liver fibrosis S ≥ 2 (OR = 11.8, 95% CI = 2.0 - 69.2, p = 0.006). ELOVL7 was significantly upregulated in patients with various types of liver injury including hepatitis B virus (HBV) infection and fatty liver diseases, and in multiple liver injury models, including bile duct ligation (BDL), carbon tetrachloride (CCl4) and paracetamol injection-induced liver damage models (all p < 0.05). The ELOVL7 levels were significantly higher in HSCs than in other liver cells (all p < 0.05) and were significantly upregulated in activated HSCs compared to quiescent HSCs (all p < 0.05). In addition, ELOVL7 expression was positively associated with transforming growth factor β (TGFβ) and bone morphogenic protein 9 (BMP9) expression and negatively associated with BMP7 expression. Bioinformatic analysis of functional enrichment indicated that ELOVL7 is mainly involved in fatty acid synthesis and metabolism. CONCLUSIONS ELOVL7 could accurately predict advanced liver fibrosis. It might be involved in the activation of HSCs and the TGFβ signaling pathway.

Abstract
Mitogen-activated protein kinases (MAPKs) are a family of Ser/Thr (serine/threonine) protein kinases that play very important roles in plant responses to biotic and abiotic stressors. However, the MAPK gene family in the important crop walnut (Juglans regia L.) has been less well studied compared with other species. We discovered 25 JrMAPK members in the Juglans genome in this study. The JrMAPK gene family was separated into four subfamilies based on phylogenetic analysis, and members of the same subgroup had similar motifs and exons/introns. A variety of cis-acting elements, mainly related to the light response, growth and development, stress response, and hormone responses, were detected in the JrMAPK gene promoters. Collinearity analysis showed that purification selection was the main driving force in JrMAPK gene evolution, and segmental and tandem duplications played key roles in the expansion of the JrMAPK gene family. The RNA-Seq (RNA Sequencing) results indicated that many of the JrMAPK genes were expressed in response to different levels of Colletotrichum gloeosporioides infection. JrMAPK1, JrMAPK3, JrMAPK4, JrMAPK5, JrMAPK6, JrMAPK7, JrMAPK9, JrMAPK11, JrMAPK12, JrMAPK13, JrMAPK17, JrMAPK19, JrMAPK20, and JrMAPK21 were upregulated at the transcriptional level in response to the drought stress treatment. The results of this study will help in further investigations of the evolutionary history and biological functions of the MAPK gene family in walnut.

Abstract
Walnut (Juglans regia L.) is an important woody oilseed tree species due to its commercial value. However, the regulation mechanism of walnut oil accumulation is still poorly understood, which restricted the breeding and genetic improvement of high-quality oil-bearing walnuts. In order to explore the metabolic mechanism that regulates the synthesis of walnut oil, we used transcriptome sequencing technology and metabolome technology to comprehensively analyze the key genes and metabolites involved in oil synthesis of the walnut embryo at 60, 90, and 120 days after pollination (DAP). The results showed that the oil and protein contents increased gradually during fruit development, comprising 69.61% and 18.32% of the fruit, respectively, during ripening. Conversely, the contents of soluble sugar and starch decreased gradually during fruit development, comprising 2.14% and 0.84%, respectively, during ripening. Transcriptome sequencing generated 40,631 unigenes across 9 cDNA libraries. We identified 51 and 25 candidate unigenes related to the biosynthesis of fatty acid and the biosynthesis of triacylglycerol (TAG), respectively. The expression levels of the genes encoding Acetyl-CoA carboxylase (ACCase), long-chain acyl-CoA synthetases (LACS), 3-oxoacyl-ACP synthase II (KASII), and glycerol-3-phosphate acyl transfer (GPAT) were upregulated at 60 DAP relative to the levels at 90 and 120 DAP, while the stearoyl-ACP-desaturase (SAD) and fatty acid desaturase 2 (FAD2) genes were highly abundantly expressed during all walnut developmental periods. We found that ABSCISIC ACID INSENSEITIVE3 (ABI3), WRINKLEDl (WRI1), LEAFY COTYLEDON1 (LEC1), and FUSCA3 (FUS3) may be key transcription factors involved in lipid synthesis. Additionally, the metabolomics analysis detected 706 metabolites derived from 18 samples, among which, 4 are implicated in the TAG synthesis, 2 in the glycolysis pathway, and 5 in the tricarboxylic acid cycle (TCA cycle) pathway. The combined analysis of the related genes and metabolites in TAG synthesis showed that phospholipid:diacylglycerol acyltransferase (PDAT) genes were highly abundantly expressed across walnut fruit developmental periods, and their downstream metabolite TAG gradually accumulated with the progression of fruit development. The FAD2 gene showed consistently higher expression during fruit development, and its downstream metabolites 18:2-PC and 18:3-PC gradually accumulated. The ACCase, LACS, SAD, FAD2, and PDAT genes may be crucial genes required for walnut oil synthesis. Our data will enrich public databases and provide new insights into functional genes related to lipid metabolism in walnut.

Abstract
UNLABELLED Currently, there is no reproducible, widely accepted gold standard to classify osteoporotic vertebral body fractures (OVFs). The purpose of this study is to refine a method with clear rules to classify OVFs for machine learning purposes. The method was found to have moderate interobserver agreement that improved with training. INTRODUCTION The current methods to classify osteoporotic vertebral body fractures are considered ambiguous; there is no reproducible, accepted gold standard. The purpose of this study is to refine classification methodology by introducing clear, unambiguous rules and a refined flowchart to allow consistent classification of osteoporotic vertebral body fractures. METHODS We developed a set of rules and refinements that we called m2ABQ to classify vertebrae into five categories. A fracture-enriched database of thoracic and lumbar spine radiographs of patients 65 years of age and older was retrospectively obtained from clinical institutional radiology records using natural language processing. Five raters independently classified each vertebral body using the m2ABQ system. After each annotation round, consensus sessions that included all raters were held to discuss and finalize a consensus annotation for each vertebral body where individual raters' evaluations differed. This process led to further refinement and development of the rules. RESULTS Each annotation round showed increase in Fleiss kappa both for presence vs absence of fracture 0.62 (0.56-0.68) to 0.70 (0.65-0.75), as well as for the whole m2ABQ scale 0.29 (0.25-0.33) to 0.54 (0.51-0.58). CONCLUSION The m2ABQ system demonstrates moderate interobserver agreement and practical feasibility for classifying osteoporotic vertebral body fractures. Future studies to compare the method to existing studies are warranted, as well as further development of its use in machine learning purposes.

Abstract
Vascular smooth muscle cells (VSMCs) play a key role in vascular calcification, which is associated with enhanced mortality in chronic kidney disease. To ascertain the concentration of parathyroid hormone (PTH) that induces apoptosis of VSMCs and to explore whether the mechanism of endoplasmic reticulum (ER) stress is involved in PTH-induced calcification of VSMCs. The appropriate concentration and intervention time of PTH-inducing apoptosis of VSMCs were screened by flow cytometry. To investigate the effects of PTH on ER stress-related and apoptotic proteins in VSMCs, they were divided into four groups. These were the control group, the PTH group, the siC/EBP homologous protein (CHOP) + PTH group (in which siCHOP was used to knockdown the expression of CHOP at first), and the sp600125 + PTH group (in which the cells were pretreated with sp600125 at a concentration of 10 ng/ml for 24 h at first). Then, all groups except the control group were given 1x10-6 mol/L PTH to stimulate VSMCs. The changes in ER stress and apoptosis-related proteins in each group were detected, and the cell calcification was tested by Alizarin Red staining. Flow cytometry showed that the concentration of 1x10-6 mol/L PTH induced apoptosis most significantly. The apoptosis rate of the cells increased with the extension of stimulation time. The apoptosis of VSMCs pretreated with the Jun-N-terminal kinase (JNK) antagonist sp600125 was significantly reduced. The expression of cleaved caspase-3, PERK, IRE1, and CHOP was detected by Western blot analysis when cells were stimulated with 10-6 mol/L PTH for 14 days. After the knockdown of the CHOP expression by siCHOP, cleaved caspase-3 expression was significantly reduced. Alizarin Red staining showed siCHOP and sp600125 inhibits the VSMCs' calcification induced by PTH. In conclusion: the ER stress mechanism is involved in VSMCs' calcification induced by PTH.

Abstract
Objective: We evaluated the safety and efficacy of lipoprotein apheresis (LA) in patients with familial hypercholesterolemia (FH) who can't reach low-density lipoprotein cholesterol(LDL-C) target goals with the maximal tolerated dose of lipid-lowering agents. Methods: This was a retrospective cross-sectional study. Between February 2015 and November 2019, patients with FH who were admitted in Fuwai hospital and treated with LA were consecutively enrolled. Based on intensive lipid-lowering agents, these patients received LA by double filtration plasma pheresis (DFPP) method. The changes of lipid levels such as LDL-C and lipoprotein(a)[Lp(a)] were compared before and after LA treatment, and the changes of immunoglobulin (Ig) concentration and LA-related adverse effects were also discussed. Results: A total of 115 patients with FH were enrolled in this study, of which 8 cases were homozygous FH and 107 cases were heterozygous FH. The age was (43.9±12.2) years and there were 75 (65.2%) males, and 108 (93.8%) with coronary artery disease. For pre-and immediately after LA treatment, the LDL-C was (5.20±2.94) mmol/L vs. (1.83±1.08) mmol/L, Lp(a) concentration was 428.70(177.00, 829.50)mg/L vs. 148.90(75.90, 317.00) mg/L (P<0.001), with a decrease of 64.2% and 59.8% respectively. The levels of IgG and IgA measured 1 day after LA treatment were both in the normal range and IgM concentration was below the reference value, the reductions of which were 15.1%, 25.0% and 58.7% respectively (P<0.001). Six patients had mild symptoms of nausea, hypotension dyspnea and palpitation, the symptoms were relieved by symptomatic treatment. Conclusion: For patients with FH who do not achieve LDL-C target goal with the maximal tolerated lipid-lowering agents, especially those with elevated Lp(a) levels, LA, which can significantly further reduce LDL-C and Lp(a) levels, is an effective and safe option.

Abstract
BackgroundBAT1806/BIIB800 is a proposed biosimilar to reference tocilizumab (TCZ). A Phase III randomised, double-blind, active-controlled clinical trial was conducted as part of a biosimilar development programme.ObjectivesTo evaluate the efficacy, pharmacokinetics (PK), safety and immunogenicity of BAT1806/BIIB800 in comparison with EU-sourced TCZ in subjects with moderate to severe rheumatoid arthritis with inadequate response to methotrexate (MTX).MethodsThe study was conducted at 55 centres in China and Europe, between June 2018 and January 2021. Eligible subjects were randomised in a 2:1:1 ratio to one of three treatment groups: (1) BAT1806/BIIB800 up to Week 48, (2) TCZ up to Week 48, or (3) TCZ up to Week 24, followed by BAT1806/BIIB800 from Week 24 to Week 48, administered intravenously every 4 weeks at a dose of 8mg/kg. The primary endpoint was the proportion of subjects achieving an ACR20 response at timepoints pre-specified to meet the requirements of different Regulatory Agencies: Week 12, for EMA; Week 24, for FDA and NMPA. Equivalence margins applied to differences in ACR20 response rates in the BAT1806/BIIB800 and TCZ treatment groups were pre-specified as follows: +/- 14.5% for EMA (95% confidence interval (CI)); -12.0%,15% for FDA (90% CI); +/- 13.6% for NMPA (95% CI). Secondary endpoints included pharmacokinetics, safety and immunogenicity.The ICH E9(R1) estimands framework including intercurrent events (related or unrelated to the COVID19 pandemic) was implemented for the ACR20 evaluation. A logistic regression model including ‘region’ (China and Eastern Europe) and ‘previous biologic or targeted synthetic DMARD use’ (Yes/No) as captured in Interactive Web Response System as stratification factors was utilised to assess equivalence for the primary endpoint. The difference in response rates was estimated and corresponding confidence intervals were derived to assess equivalence for the primary endpoint. This abstract presents results up to Week 24.ResultsIn total, 621 subjects were randomised to receive BAT1806/BIIB800 (N=312), TCZ (N=155), or TCZ followed by BAT1806/BIIB800 (N=154). The groups were comparable in terms of baseline demographics and disease characteristics, including age, gender, disease activity and disease duration. The estimated proportions of subjects achieving an ACR20 response in the BAT1806/BIIB800 vs. the TCZ groups, respectively, were 68.97% vs. 64.82% at Week 12 and 69.89% vs. 67.94% at Week 24. The estimated difference between ACR response rates was 4.15% (95% CI -3.63, 11.93) at week 12, and 1.94% (90% CI -4.04, 7.92; 95% CI -5.18, 9.07) at Week 24. The CIs for the estimated differences between the treatment groups were within the pre-defined equivalence margins (Figure 1).

Abstract
Background Upper tracheal surgery is used to treat patients who with tracheal tumors or tracheal stenosis. The non-intubated spontaneous ventilation anesthesia (NSVA) may have advantages over endotracheal intubation and surgical cross-field intubation in upper tracheal surgery. This study aimed to illustrate and assess the feasibility of NSVA strategy for upper tracheal surgery. Methods This is a retrospective case series study in which 51 patients (from May 2015 to August 2020) who met the criteria in NSVA strategy were analyzed. Anesthesia was performed using total intravenous anesthesia (TIVA) combined with bilateral superficial cervical plexus block (CPB) or thoracic epidural anesthesia (TEA). Patients received spontaneous ventilation through laryngeal mask airway (LMA) during the surgery. Anesthesia conversion technique was applied to patients who met the anesthesia conversion criteria. Results In total, 51 patients met the NSVA criteria and were included in this study. Forty-six out of 51 patients (90%) had TIVA + bilateral superficial CPB and five patients (10%) had TIVA + TEA + CPB. During the airway-opened period, 46 patients had stable spontaneous ventilation. Five patients need anesthesia conversion, two patients had high-frequency ventilation (HFV), and three patients required cross-field intubation. Postoperative complications occurred in seven (14%) patients, no reintubation was needed after surgery. The median postoperative hospital stay was 6.31±4.30 days. Conclusions This NSVA strategy includes criteria for patient selection, preoperative assessment, surgical technique, airway management, criteria and technique for anesthesia conversion. The NSVA strategy is a feasible procedure in upper tracheal surgery.

Abstract
Drought stress is an environmental factor that seriously threatens plant growth, development and yield. VQ proteins are transcriptional regulators that have been reported to be involved in plant growth, development and the responses to biotic and abiotic stressors. However, the relationship between VQ proteins and drought stress has not been well documented in plants. In this study, overexpressing the apple VQ motif-containing protein (MdVQ37) gene in apple plants markedly reduced the tolerance to drought. Physiological and biochemical studies further demonstrated lower enzymatic activities and decreased photosynthetic capacity in transgenic lines compared with wild-type (WT) plants under drought stress. Ultrastructural analysis of leaves showed that the leaves and palisade tissues from the transgenic lines were significantly thinner than those from WT plants. Salicylic acid (SA) analysis indicated that overexpression of MdVQ37 increased the accumulation of 2,5-DHBA by up-regulating the expression of the SA catabolic gene, which ultimately resulted to a significant reduction in endogenous SA content and the disruption of the SA-dependent signaling pathway under drought stress. Applying SA partially increased the survival rate of the transgenic lines under drought stress. These results demonstrate that the regulatory function of apple MdVQ37 is implicated in drought stress, through a change in leaf development and SA homeostasis. This study provides novel insight into understanding the multiple functions of VQ proteins.

Abstract
High temperature (HT) is one of the most important environmental stress factors and seriously threatens plant growth, development, and production. VQ motif-containing proteins are transcriptional regulators that have been reported to regulate plant growth and developmental processes, including responses to biotic and abiotic stresses. However, the relationships between VQ motif-containing proteins and HT stress have not been studied in depth in plants. In this study, transgenic apple (Malus domestica) plants overexpressing the apple VQ motif-containing protein-coding gene (MdVQ37) were exposed to HT stress, and the transgenic lines exhibited a heat-sensitive phenotype. In addition, physiological and biochemical studies revealed that, compared with WT plants, transgenic lines had lower enzymatic activity and photosynthetic capacity and lower amounts of nonenzymatic antioxidant system metabolites under HT stress. Transcriptome analysis revealed 1379 genes whose expression differed between the transgenic lines and WT plants. GO and KEGG pathway analyses showed that transcription factor activity and plant hormone signaling pathways were differentially influenced and enriched in the transgenic lines. Salicylic acid (SA) content analysis indicated that overexpression of MdVQ37 reduced the content of endogenous SA by regulating the expression of SA catabolism-related genes, which ultimately resulted in disruption of the SA-dependent signaling pathway under HT stress. The application of SA slightly increased the survival rate of the transgenic lines under HT stress. Taken together, our results indicate that apple MdVQ37 has a regulatory function in basal thermotolerance by modulating the activity of transcription factors and SA homeostasis. Overall, this study provides novel insights that improve our understanding of the various functions of VQ motif-containing proteins.

Abstract
Prevention of bacterial infection and reduction of hemorrhage, the primary challenges posed by trauma before hospitalization, are essential steps in prolonging the patient's life until they have been transported to a trauma center. Extracellular matrix (ECM) hydrogel is a promising biocompatible material for accelerating wound closure. However, due to the lack of antibacterial properties, this hydrogel is difficult to be applied to acute contaminated wounds. This study formulates an injectable dermal extracellular matrix hydrogel (porcine acellular dermal matrix (ADM)) as a scaffold for skin defect repair. The hydrogel combines vancomycin, an antimicrobial agent for inducing hemostasis, expediting antimicrobial activity, and promoting tissue repair. The hydrogel possesses a porous structure beneficial for the adsorption of vancomycin. The antimicrobial agent can be timely released from the hydrogel within an hour, which is less than the time taken by bacteria to infest an injury, with a cumulative release rate of approximately 80%, and thus enables a relatively fast bactericidal effect. The cytotoxicity investigation demonstrates the biocompatibility of the ADM hydrogel. Dynamic coagulation experiments reveal accelerated blood coagulation by the hydrogel. In vivo antibacterial and hemostatic experiments on a rat model indicate the healing of infected tissue and effective control of hemorrhaging by the hydrogel. Therefore, the vancomycin-loaded ADM hydrogel will be a viable biomaterial for controlling hemorrhage and preventing bacterial infections in trauma patients.

Abstract
Objective: To explore the effect of the resection of the primary lesion on the prognosis for patients with stage Ⅳ breast cancer. Methods: A total of 132 breast cancer patients who were first diagnosed as stage Ⅳ in the Hebei Cancer Hospital from June 2008 to June 2015 were divided into two groups: the primary resection group (n=85) and the unresection group (n=47). The influences of primary resection, timing of operation, lymph node removal or dissection and radiotherapy on the prognosis of stage Ⅳ breast cancer patients were analyzed. Results: Multivariate Logistic regression analysis showed that visceral metastasis was an independent influencing factor for primary lesion resection in stage Ⅳ breast cancer patients (OR=2.590, 95% CI: 1.090-6.159). Multivariate Cox regression analysis showed that primary resection was an independent factor for the improvement of prognosis in stage Ⅳ breast cancer patients (OR=0.582, 95% CI: 0.400-0.847). The median overall survival (OS) was 37.20 months in the resection group, which was higher than 24.10 months in the unresection group (χ(2)=8.108, P=0.004). Among patients aged ≥50 years old, the median OS was 39.30 months in the resection group and 23.03 months in the unresection group, and the difference was statistically significant (χ(2)=14.191, P<0.001). The median OS was 38.00 months in the 66 patients with the operation time from diagnosis to resection of primary lesion<6 months (n=66), and 35.20 months for ≥6 months (n=19) (χ(2)=4.430, P=0.035), the difference was statistically significant (χ(2)=4.430, P=0.035). The median OR of axillary lymph node dissection and axillary lymph node excision group were 45.37 months and 33.44 months, respectively, the difference was statistically significant (χ(2)=7.832, P=0.005). The median OS of postoperative radiotherapy group and non-radiotherapy group were 44.80 months and 33.20 months, respectively, the difference was not statistically significant (χ(2)=2.950, P=0.086). Conclusion: Resection of the primary lesion may prolong the survival time of some advanced breast cancer patients.

Abstract
BACKGROUND Subjective cognitive decline (SCD) as an early pathological manifestation of brain aging has become more prevalent among older adults. OBJECTIVES We aimed to investigate the associations of subjective cognitive decline (SCD) with the combined risk of cognitive impairment and dementia. DESIGN We performed a systematic review and meta-analysis via searching Embase, PubMed and Cochrane electronic databases from January 1 st 1970 to June 4th, 2020. SETTING Prospective cohort studies Participants: Healthy individuals were recruited from community, clinics and population. MEASUREMENTS Healthy individuals with SCD were classified into exposure groups, while those without were considered as the reference group. Adjusted relative risks (RR) were estimated in a random-effects model. Both primary and subgroup analyses were conducted. RESULTS Of 28,895 identified studies, 21 studies containing 22 cohorts were eligible for inclusion in the meta-analysis. SCD increased the risk of subsequent cognitive disorders (RR=2.12, 95% confidence intervals [CI] =1.75-2.58, I2=87%, P<0.01). To be specific, SCD conferred a 2.29-fold excess risk for cognitive impairment (RR=2.29, 95% CI=1.66-3.17, I2=83%, P<0.01) and a 2.16-fold excess risk for dementia (RR=2.16, 95% CI=1.63-2.86, I2=81%, P<0.01). In subgroup analyses, participants with SCD in the subgroup of 65-75 years old, long-education (>15 years) subgroup and subgroup of clinics showed a higher risk of developing objective cognitive disorders. CONCLUSIONS SCD is associated with an increased combined risk of cognitive impairment and incident dementia and should be considered a risk factor for objective cognitive disorders.

Abstract
Abiotic stresses are major environmental factors inhibiting plant growth and development. AITRs (ABA-induced transcription repressors) are a novel family of transcription factors regulating ABA (abscisic acid) signalling and plant responses to abiotic stresses in Arabidopsis. However, the composition and evolution history of AITRs and their roles in the cotton genus are largely unknown. A total of 12 putative AITRs genes were identified in cultivated tetraploid cotton, Gossypium hirsutum. Phylogenetic analysis of GhAITRs in these tetraploid cottons and their closely related species implicate ancient genome-wide duplication occurring after speciation of Gossypium, and Theobroma could generate duplicates of GhAITRs. Duplicated GhAITRs were stably inherited following diploid speciation and further allotetraploidy in Gossypium. Homologous GhAITRs shared common expression patterns in response to ABA, drought and salinity treatments, and drought tolerance induced in transgenic Arabidopsis plants expressing GhAITR-A1. Together, our findings reveal that duplicates in the GhAITRs gene family were achieved by whole genome duplication rather than three individual duplication events, and that GhAITRs function as transcription repressors and are involved in the regulation of plant responses to ABA and drought stress. These results provide insights towards the improvement of abiotic stress tolerance in cotton using GhAITRs.

Abstract
Traditionally, the healthy urinary bladder has been considered to be sterile. Several teams have used metagenomic (DNA-dependent) and metaculturomic (culture-dependent) methods to debunk this longstanding dogma. In fact, resident microbial communities (urobiome) have been detected in both adult females and males. Although the field is young, several observations have been made. For example, the urobiome differs between men and women, likely due to anatomical and hormonal differences. Importantly, the urobiome has been associated with a variety of lower urinary tract disorders, including overactive bladder and post-operative urinary tract infection, raising the possibility that clinicians might one day treat symptoms by modifying the urobiome instead of killing the suspected uropathogen. Little is known concerning the relationship between the urobiome and host genetics; so far, only a single paper has reported such a study. However, major efforts have gone into understanding the genomics of the urobiome itself, a process facilitated by the fact that many urobiome studies have used metaculturomic methods to detect and identify microbes. In this narrative review, we will introduce the urobiome with separate sections on the female and male urobiomes, discuss challenges specific to the urobiome, describe newly discovered associations between the urobiome and lower urinary tract symptoms, and highlight the one study that has attempted to relate host genetics and the urobiome. We will finish with a section on how metagenomic surveys and whole genome sequencing of bacterial isolates are improving our understanding of the urobiome and its relationship to lower urinary tract health and disorders.

Abstract
BACKGROUND Calcium (Ca2+) plays an important role in plant growth and development, and the maintenance of calcium homeostasis is necessary for the survival of all plant species. Ca2+/H+ exchangers (CAXs) are a subgroup of the CaCA (Ca2+/cation antiporter) superfamily. In general, CAX proteins mediate cytosolic Ca2+ entry into vacuoles to prevent excessive accumulation of Ca2+ in the cytosol. The CaCA superfamily has been identified and characterised in many plant species; however, characterisation of the CaCA superfamily and functional study of apple CAX proteins have yet to be conducted in apple (Malus × domestica Borkh.). RESULTS Here, we identified 21 CaCA family proteins in apple for the first time. Phylogenetic and gene structure analysis, as well as prediction of conserved motifs, suggested that these proteins could be classified into four groups: CAX, CCX, NCL, and MHX. Expression analysis showed that the 10 MdCAX genes we cloned strongly responded to calcium and abiotic stress treatments. Collinearity analysis and characterisation of calcium transport capacity resulted in the identification of a pair of segmental duplication genes: MdCAX3L-1 and MdCAX3L-2; MdCAX3L-2 showed strong calcium transport capacity, whereas MdCAX3L-1 showed no calcium transport capacity. Yeast two-hybrid (Y2H) assays showed that these two proteins could interact with each other. The high sequence similarity (94.6%) makes them a good model for studying the crucial residues and structural basis of the calcium transport of CAX proteins. Prediction of the protein interaction network revealed several proteins that may interact with CAX proteins and play important roles in plant stress responses, such as SOS2, CXIP1, MHX, NRAMP3, and MTP8. CONCLUSIONS Our analysis indicated that MdCAX proteins have strong calcium transport capacity and are involved in the abiotic stress response in apple. These findings provide new insight and rich resources for future studies of MdCAX proteins in apple.

Abstract
Objective: To analyze the clinical and genetic characteristics of primary hypoparathyroidism in children. Methods: The clinical data including age, symptoms, laboratory examination and cranial CT of 13 children with primary hypoparathyroidism diagnosed in the Capital Institute of Pediatrics from May 2017 to December 2019 were collected and analyzed retrospectively. These children and their parents also had gene detected by whole exome sequencing and (or) copy number variation sequencing. Results: Among the 13 patients, 7 were male and 6 female. The onset age was 3 years (1 day-12 years) old. The time from onset to confirmed diagnosis was 2 months (2 days-10 years). The clinical manifestations included convulsion (9 cases), tetany (2 cases), muscle pain (1 case), mental retardation (5 cases), deafness (1 case), and initially misdiagnosed epilepsy (5 cases). The lab examination showed average blood calcium level of (1.7±0.3) mmol/L, blood phosphorus of (2.8±0.4) mmol/L, and parathyroid hormone of 8.2 (3.9-28.7)ng/L. Head CT found 7 cases of ectopic calcification. Among the 7 cases who had genetic abnormalities according to the gene detection, 5 had heterozygous deletion of 22q11.2 region, and only one of whom was diagnosed with typical DiGeorge syndrome. As for the rest 2 cases, one had autosomal dominant hypocalcemia caused by novel heterozygous variation of CaSR gene c.2495T>G (p.F832C), and the other was hypoparathyroidism-deafness-renal dysplasia syndrome caused by GATA3 c.708dupC (p.S237Qfs*66) novel heterozygous variation. Conclusions: Primary hypoparathyroidism in children is mainly characterized by hypocalcemia and usually accompanied with diverse symptoms which may indicate genetic disorders. The detection of large fragment deletion should be considered to exclude 22q11.2 deletion syndrome.

Abstract
OBJECTIVE MicroRNAs (miRNAs) have been demonstrated to have crucial roles in cancer development. We investigated the involvement of miR-223-3p in neuroblastoma (NB). MATERIALS AND METHODS MiR-223-3p expression in NB cell lines and normal cell line was analyzed with real-time quantitative PCR method. Cell proliferation, cell invasion, and cell apoptosis were assessed by cell counting kit-8 (CCK-8), transwell invasion assay, and flow cytometry assay, respectively. Bioinformatics analysis, Dual-Luciferase reporter assays, and Western blot analysis were conducted to identify the connection of miR-223-3p and forkhead box O1 (FOXO1). RESULTS MiR-223-3p level was found highly expressed in NB cell lines compared with normal cell line. Knockdown miR-223-3p expression decreased cell growth and invasion but increased cell apoptosis. MiR-223-3p was able to bind with the 3'-untranslated region of FOXO1, and thereby resulting in a reduction of FOXO1 expression. The knockdown of FOXO1 increased the malignant capacity of NB cells. CONCLUSIONS Therefore, given the fact that miR-223-3p suppressed FOXO1 expression to promote NB progression, targeting miR-223-3p may be an effective method for NB treatment.

Abstract
OBJECTIVE Metastasis is one of the main causes of leading recurrence and death in patients with hepatocellular carcinoma (HCC). XRCC5 can affect several types of human cancers. The aim of the present study is to explore the metastasis correlation between the expression level of XRCC5 protein in HCC cell lines with different metastatic potentials and the prognosis of patients with HCC. MATERIALS AND METHODS Hepatocellular carcinoma cell lines used in this study include MHCC97-H, MHCC97-L, HepG2, and HL-7702. RESULTS XRCC5 was widely expressed in HCC cell lines analyzed by Real-Time Reverse Transcription PCR and Western blotting. The levels of XRCC5 protein and mRNA were positively correlated with the migration and invasion capability of HCC cell lines. SiRNA-XRCC5 significantly suppressed the migration and invasion of HCC cells. Immunohistochemistry (IHC) results showed that high-expressed XRCC5 in patients with HCC was associated with advanced tumors, size, and microvascular invasion and lower overall survival time than the low-expressed. The expression levels of CTNNB1 and MMP9 decreased by knocked down XRCC5 which may promote the progression of HCC via the Wnt/β-catenin signaling pathway. CONCLUSIONS Our results suggest that the high expression of XRCC5 predicts poor prognosis in patients with HCC, and XRCC5 may be a potential biomarker to inhibit the invasion and migration of HCC.

Abstract
Abiotic stresses threaten the productivity and quality of economically important perennial fruit crops such as apple (Malus × domestica Borkh.). WRKY transcription factors play various roles in plant responses to abiotic stress, but little is known regarding WRKY genes in apple. Here, we carried out functional characterization of an apple Group IIa WRKY gene (MdWRKY30). qRT-PCR analysis found that MdWRKY30 expression was induced by salt and drought stress. A subcellular localization assay showed that MdWRKY30 is localized to the nucleus. A transactivation assay found that MdWRKY30 has no transcriptional activation activity. A Y2H assay indicated that MdWRKY26, MdWRKY28, and MdWRKY30 interact with each other to form heterodimers and homodimers. Transgenic analysis revealed that the overexpression of MdWRKY30 in Arabidopsis enhanced salt and osmotic tolerance in the seedling stage, as well as during the seed germination and greening cotyledon stages. MdWRKY30 overexpression enhanced tolerance to salt and osmotic stresses in transgenic apple callus through transcriptional regulation of stress-related genes. Together, our results demonstrate that MdWRKY30 is an important regulator of salinity and osmotic stress tolerance in apple.

Abstract
In higher plants, the light-harvesting chlorophyll a/b-binding (Lhc) proteins function in multiple processes that are critical to plant growth, development, and abiotic stress response. However, the Lhc gene family has not been well characterized in the important fruit crop, apple (Malus × domestica Borkh.). In this study, we identified 27 Lhc genes in the apple genome. Phylogenetic analysis showed that the Lhc gene family could be classified into three major subfamilies, each of whose members shared similar conserved motifs. Evolutionary analysis indicated that duplicated MdLhc genes were primarily under purifying selection. MdLhcs were expressed at varying levels in all tissues examined and showed different expression patterns under drought stress. The overexpression of MdLhcb4.3 in transgenic Arabidopsis and apple callus enhanced their tolerance to drought and osmotic stress. Taken together, these results demonstrate the important role of Lhc proteins in the regulation of plant resistance to drought and osmotic stress and provide valuable information for further study of Lhc functions in apple.

Abstract
BACKGROUND AND PURPOSE Thrombectomy up to 24 hours after stroke onset in patients with specific ischemic brain volumes remains a challenge, because many stroke centers do not apply specialized software to calculate ischemic volumes at advanced imaging. We aimed to establish the association between relative filling time delay on CTP source imaging and ischemic volume parameters and the infarct penumbra to core volume mismatch in patients with acute ischemic stroke. MATERIALS AND METHODS Consecutive patients with acute ischemic stroke and with M1 segment MCA with or without terminal ICA occlusions on baseline CTA and CTP within 24 hours of stroke symptom onset were included. Ischemic volumes were analyzed with software based on CTP maps. Relative filling time delay was classified into 4 grades-grade 0: relative filling time delay = 0 seconds; grade 1: relative filling time delay >0 to ≤4 seconds; grade 2: relative filling time delay >4 to ≤8 seconds; and grade 3: relative filling time delay > 8 seconds. Differences in ischemic volume parameters among relative filling time delay grades were tested. RESULTS We recruited 138 patients (median age, 69 years; 62.3% male). Different median volumes of the infarct core (grade 0, 7.3 mL; grade 1, 23.3 mL; grade 2, 45.7 mL; grade 3, 135 mL [P < .001]) and the penumbra (grade 0, 47.6 mL; grade 1, 90 mL; grade 2, 110 mL; grade 3, 92 mL [P = .043]) were observed among relative filling time delay grades. Target mismatch (defined by the criteria of the DEFUSE 3 trial) was identified in 71.7% of the patients (99/138). A relative filling time delay grade ≤ 1 independently predicted target mismatch, with a sensitivity of 0.79 (95% CI, 0.7-0.87) and a specificity of 0.66 (95% CI, 0.49-0.8). CONCLUSIONS Relative filling time delay grade based on CTP source imaging is a simple and effective parameter for evaluating ischemic volumes and target mismatch in patients with acute ischemic stroke. Further studies that compare relative filling time delay grade with clinical functional outcomes are necessary.

Abstract
Malus sieversii is the wild progenitor for many cultivars of domesticated apple and an important germplasm resource for breeding. However, this valuable species faces a significant threat in the areas north of the Tianshan Mountains in China, by the invasion of Agrilus mali, a destructive pest of apple trees belonging to the family Buprestidae. Our preliminary study has has shown that there may be resistance to this insect in M. sieversii plants in the field, but the corresponding molecular mechanisms remain unclear. In this study, we compared the response of insect-resistant and insect-susceptible plants of M. sieversii to insect feeding using full-length transcriptome and targeted metabolome. 112,103 non-chimeric full-length reads (FLNC) totaling 10.52 Gb of data were generating with Pacific Biosciences SingleMolecule, Real-Time (PacBio SMRT) sequencing. A total of 130.06 Gb data of long reads were acquired with an Illumina HiSeq. Function annotation indicated that the different expressed genes (DEGs) were mainly involved in signal transduction pathway of plant hormones and in the synthesis of compounds such as terpenes, quinones, flavonoids, and jasmonic acid. Through targeted metabolome analysis resistant strains showed higher levels of trans-cinnamic acid, caffeine and ferulic acid after pest infestation. This study helps to decipher the transcriptional changes and related signaling paths in M. sieversii after an insect feeding, which lays a foundation for further research on molecular mechanisms of insect resistance in apples.

Abstract
BACKGROUND NAC transcription factors play important roles in the regulation of plant growth, development, abiotic and biotic stress responses. The transcriptional level of MdNACs in different tissues and under various biotic and abiotic stress treatments was determined to provide a solid foundation for studying the function of MdNACs. METHODS Thirty-two full-length cDNA sequences of Md NACs were isolated by homologous comparison and RT-PCR confirmation, and the obtained cDNA sequences and the deduced amino acid sequences were analyzed with bioinformatics methods. The prediction of subcellular locations of MdNAC proteins was performed using CELLO v.2.5, PSORT, and SoftBerry ProtComp 9.0. Expression levels of MdNACs were detected in 16 different tissues using an array. Expression patterns of MdNACs were detected in response to Alternaria alternata apple pathotype (AAAP) infection using RNA-seq, and the expression of MdNACs was analyzed under NaCl and mannitol treatments using RT-qPCR. RESULTS The sequencing results produced 32 cDNAs (designated as MdNAC24-39, MdNAC54-65, and MdNAC67-70 with GenBank accession No. MG099861-MG099876, MG099891-MG099902, and MG099904-MG099907, respectively). Phylogenetic analysis revealed that MdNAC34 belonged to the ATAF group, MdNAC63 belonged to the AtNAC3 group, MdNAC24, MdNAC26-30, MdNAC32-33, MdNAC35, MdNAC37-39, MdNAC56-57, MdNAC59-62, MdNAC64-65, and MdNAC67-70 belonged to the NAM group, and MdNAC25, MdNAC36, MdNAC54-55, and MdNAC58 belonged to the VND group. Predictions of subcellular localization showed that MdNAC24-27, MdNAC29-30, MdNAC33-37, MdNAC39, MdNAC54-65, and MdNAC67-70 proteins were located in the nucleus, MdNAC28 proteins were located in the cytoplasm, MdNAC31-32 proteins were located in the nucleus and cytoplasm, and MdNAC38 proteins were located in the nucleus and plasma membrane. Array results indicated that 32 MdNACs were expressed in all examined tissues at various expression levels. RNA-seq results showed that expression levels of MdNAC26-28, MdNAC33-34, MdNAC60, MdNAC62-65, and MdNAC68 were induced, but MdNAC24, MdNAC32, and MdNAC58 were down-regulated in response to AAAP infection. Under salt treatment, MdNAC24, MdNAC27, MdNAC29, MdNAC34, MdNAC37, MdNAC39, MdNAC54, MdNAC59, and MdNAC63 transcription levels were induced. Under mannitol treatment, MdNAC32 and MdNAC54 transcription levels were induced, but MdNAC24, MdNAC28, MdNAC30, MdNAC33, MdNAC35, MdNAC37, MdNAC55, MdNAC56, MdNAC58, and MdNAC59 were down-regulated. Taken together, the results indicated that the cloned MdNAC genes were expressed constitutively in all examined tissues. These genes were up-regulated or down-regulated in response to AAAP infection and to salt or mannitol, which suggested they may be involved in the regulation of growth, development, and stress response in apple.

Abstract
Two-dimensional systems can host exotic particles called anyons whose quantum statistics are neither bosonic nor fermionic. For example, the elementary excitations of the fractional quantum Hall effect at filling factor ν = 1/m (where m is an odd integer) have been predicted to obey Abelian fractional statistics, with a phase ϕ associated with the exchange of two particles equal to π/m However, despite numerous experimental attempts, clear signatures of fractional statistics have remained elusive. We experimentally demonstrate Abelian fractional statistics at filling factor ν = ⅓ by measuring the current correlations resulting from the collision between anyons at a beamsplitter. By analyzing their dependence on the anyon current impinging on the splitter and comparing with recent theoretical models, we extract ϕ = π/3, in agreement with predictions.

Abstract
Background Spontaneous breathing anesthesia (SBA) may have advantages over general anesthesia for cervical tracheal resection and reconstruction (TRR), avoiding the difficulties and complication caused by endotracheal intubation and surgical cross-field intubation. This prospective study evaluates SBA for cervical TRR. Methods Date was obtained from 35 patients who had cervical TRR under SBA from May 2015 to March 2019. Intravenous sedation and ultrasound-guided bilateral superficial cervical plexus block (CPB) were applied to maintain effective analgesia and sedation. Results Thirty-two patients with tracheal tumors and 3 patients with post-intubation tracheal stenosis underwent TRR. After the airway was opened, 29 patients resumed stable spontaneous breathing, 1 patient needed high-frequency jet ventilation, and 1 patient needed anesthesia conversion for surgical reasons. Conclusions Spontaneous breathing anesthesia is feasible for the cervical TRR. It can be an alternative anesthetic technique for certain patients.

Abstract
BACKGROUND AP2/ERF transcription factors are involved in the regulation of plant growth, development, and stress responses. Our research objective was to characterize novel apple (Malus × domestica Borkh.) genes encoding AP2/ERF transcription factors involved in regulation of plant growth, development, and stress response. The transcriptional level of apple AP2/ERF genes in different tissues and under various biotic and abiotic stress was determined to provide valuable insights into the function of AP2/ERF transcription factors in apple. METHODS Thirty full-length cDNA sequences of apple AP2/ERF genes were isolated from 'Zihong Fuji' apple (Malus × domestica cv. Zihong Fuji) via homologous comparison and RT-PCR confirmation, and the obtained cDNA sequences and the deduced amino acid sequences were analyzed with bioinformatics methods. Expression levels of apple AP2/ERF genes were detected in 16 different tissues using a known array. Expression patterns of apple AP2/ERF genes were detected in response to Alternaria alternata apple pathotype (AAAP) infection using RNA-seq with existing data, and the expression of apple AP2/ERF genes was analyzed under NaCl and mannitol treatments using qRT-PCR. RESULTS The sequencing results produced 30 cDNAs (designated as MdERF3-8, MdERF11, MdERF16-19, MdERF22-28, MdERF31-35, MdERF39, MdAP2D60, MdAP2D62-65, and MdRAV2). Phylogenetic analysis revealed that MdERF11/16, MdERF33/35, MdERF34/39, and MdERF18/23 belonged to groups A-2, A-4, A-5, and A-6 of the DREB subfamily, respectively; MdERF31, MdERF19, MdERF4/25/28/32, MdERF24, MdERF5/6/27, and MdERF3/7/8/17/22/26 belonged to groups B-1, B-2, B-3, B-4, B-5, and B-6 of the ERF subfamily, respectively; MdAP2D60 and MdAP2D62/63/64/65 belonged to the AP2 subfamily; and MdRAV2 belonged to the RAV subfamily. Array results indicated that 30 apple AP2/ERF genes were expressed in all examined tissues to different degrees. RNA-seq results using previously reported data showed that many members of the apple ERF and DREB subfamilies were induced by Alternaria alternate apple pathotype (AAAP) infection. Under salt treatment, many members in the apple ERF and DREB subfamilies were transcriptionally up or down-regulated. Under mannitol treatment, many members of the apple ERF, DREB, and AP2 subfamilies were induced at the transcriptional level. Taken together, the results indicated that the cloned apple AP2/ERF genes were expressed in all examined tissues. These genes were up-regulated or down-regulated in response to AAAP infection and to salt or mannitol treatment, which suggested they may be involved in regulating growth, development, and stress response in apple.

Abstract
Drought and nitrogen (N) deficiency are common factors that limit apple production in the Loess Plateau region of China. Different apple cultivars respond to drought and low N differently; however, the mechanism that underlies the difference in nitrogen-use efficiency (NUE) under drought conditions is not well understood. In this study, by comparing the physiological responses of two apple (Malus domestica Borkh.) cultivars with contrasting NUE, 'Qinguan' (higher NUE) and 'Honeycrisp' (lower NUE), under low N and drought conditions, we discovered that, 'Qinguan' had larger stomatal apertures, higher chlorophyll fluorescence levels, more active N metabolism and antioxidant enzymes, higher abscisic acid and auxin concentrations, larger root size and more efficient N uptake mediated by higher expression of MdNRT2.4 in rootstock than that of 'Honeycrisp'. Additionally, we experimentally confirmed that MdNRT2.4 enhanced low N and osmotic stress tolerance in Arabidopsis when being overexpressed. Taken together, our findings shed light on the mechanism that underlies the difference in NUE of apple under drought and N-deficient conditionss and provide MdNRT2.4 as a candidate gene for future genetic engineering.

Abstract
Auxin is a plant hormone that takes part in a series of developmental and physiological processes. There are three major gene families that play a role in the early response of auxin and auxin/indole-3-acetic acid (Aux/IAA) is one of these. Although the genomic organization and function of Aux/IAA genes have been recognized in reference plants there have only been a few focused studies conducted with non-model crop plants, especially in the woody perennial species. We conducted a genomic census and expression analysis of Aux/IAA genes in the cultivated apple (Malus × domestica Borkh.). The Aux/IAA gene family of the apple genome was identified and analyzed in this study. Phylogenetic analysis showed that MdIAAs could be categorized into nine subfamilies and that these MdIAA proteins contained four whole or partially conserved domains of the MdIAA family. The spatio-specific expression profiles showed that most of the MdIAAs were preferentially expressed in specific tissues. Some of these genes were significantly induced by treatments with one or more abiotic stresses. The overexpression of MdIAA9 in tobacco (Nicotiana tabacum L.) plants significantly increased their tolerance to osmotic stresses. Our cumulative data supports the interactions between abiotic stresses and plant hormones and provides a theoretical basis for the mechanism of Aux/IAA and drought resistance in apples.

Abstract
Abstract
Background
It has been reported that coronary artery disease (CAD) is characterized by inflammation and non-obstructive CAD (NOCAD) increases the risk of cardiovascular events (CVEs) compared with ones with normal or near-normal coronary arteries (NNCA), even is similar to obstructive CAD (OCAD). We hypothesized that elevated high-sensitivity C-reactive protein (hs-CRP) may be linked to CVEs in those patients with NOCAD.
Purpose
To investigate the predictive role of hs-CRP in patients with NOCAD.

Of 7,746 consecutive patients with angina-like chest pain admissions, 4,662 eligible patients were enrolled who received coronary artery angiography (CAG) and followed up for the CVEs comprising all-cause mortality, myocardial infarction, stroke and late revascularization. According to the results of CAG, the patients were classified as NNCA group (<20% stenosis, n=698, 15.0%), NOCAD group (20–49% stenosis, n=639, 14.3%), and OCAD group (≥50% stenosis, n=3325, 70.7%). They were further subdivided into 3 groups according to baseline hs-CRP levels (<1, 1–3 and >3 mg/L). Proportional hazards models were used to assess the risk of CVEs in all patients enrolled.
Results
A total of 338 patients (7.3%) experienced CVEs during an average of 13403 person-years follow-up. Patients with NOCAD and OCAD had higher rates of CVEs compared to those with NNCA (p<0.05, respectively). In Cox's models after adjustment of confounders, the risk of CVEs elevated with the increasing degrees of CAD with hazard ratio of 2.01 [95% confidence interval (95% CI): 1.07–3.79, p=0.03] for patients with NOCAD and 2.81 (95% CI: 1.60–4.93, p<0.001) for patients with OCAD compared with the NNCA group. Moreover, elevated hs-CRP levels were associated with the severity of coronary lesions and an elevated increased risk of CVEs in patients with NOCAD and OCAD compared those with NNCA (p<0.05, respectively).
Conclusions
Patients with NOCAD had indeed worse outcomes and hs-CRP levels were positively in relation to the CVEs in those with NOCAD, which may help to the risk assessment in ones with NOCAD.
