Abstract
Abstract
Background
The association between baseline hemoglobin A1c (HbA1c) levels before the percutaneous coronary intervention and bleeding is unclear in patients with non-ST-segment elevation acute coronary syndrome.
Purpose
To investigate the association between baseline HbA1c levels before the percutaneous coronary intervention and bleeding in patients with non-ST-segment elevation acute coronary syndrome.
Methods
This observational cohort study enrolled 6,283 consecutive patients with non-ST-segment elevation acute coronary syndrome, from 1 January 2010 to 31 December 2014. Based on baseline HbA1c levels, the patients were divided into the HbA1c <7% group (n=4,740) and the HbA1c ≥7% group (n=1,543). The primary outcomes are major bleeding events (BARC grades 3–5) and all-cause death during follow-up.
Results
Of the patients who were enrolled, 4,705 (74.9%) were male and 2,143 (34.1%) had a history of diabetes mellitus, with a mean (SD) age of 64.13 (10.32) years. Median follow-up duration was 3.21 years. Compared with HbA1c <7% patients, the risk of major bleeding events and all-cause was both higher in HbA1c ≥7% patients (major bleeding: adjusted hazard ratio, 1.62; 95% confidence interval, 1.04–2.53; P=0.032; all-cause death: adjusted hazard ratio, 1.26; 95% confidence interval, 1.03–1.55; P=0.027). The result of the subgroups analyses was consistent with the primary analyses.
Conclusions
Higher baseline HbA1c levels before percutaneous coronary intervention was associated with an increase in bleeding risk in non-ST-elevation acute coronary syndrome patients. This study suggests that the HbA1c levels should be taken into account for the prolonged antithrombotic strategies of non-ST-elevation acute coronary syndrome patients.

Abstract
Abstract
Aims
To observe the effects of trimetazidine, aerobic exercise alone or combined on the anti-stress capacity of mice, and further explore its potential mechanism.
Methods
Forty-four C57/BL male mice aged 8 weeks were randomly divided into four groups: control group (group C, n=11), exercise group (group E, n=11), trimetazidine (TMZ)group (group T, n=11),exercise combined with TMZ group (group TE, n=11). Saline intragastric administration, medium intensity swimming training, TMZ (10mg/kg) intragastric administration, medium intensity swimming training combined with TMZ intragastric administration were given respectively. Swimming for 6 days a week, 1 hour a day lasting for 4 weeks. After the intervention, each group was randomly subdivided into the rest and the exhaustive exercise (EE) subgroups. The mice in the EE-subgroup (n=6) underwent exhaustive exercise. The myocardial ultrastructure was observed under electron microscope to measure the anti-stress ability of mice. The expression of key autophagy proteins LC3-II, P62 and BNIP3 were detected and the number of myocardial autophagosomes were observed under electron microscope. The protein of apoptosis related, Bcl-2 and the expression of heat shock protein 70 (HSP70) were also being detected.
Results
Exhaustive exercise induced the cardiac muscle damage successfully. TMZ and exercise alone or combined alleviated the cardiac damage significantly with improved autophagy (P<0.05) at the basal state and after exhaustive exercise. The level of apoptosis (P<0.05) and the expression of HSP70 was upregulated after the exhaustive exercise.
Conclusions
TMZ and exercise alone improved the anti-stress capacity of mice effectively and the combination has a synergistic effect. The mechanism may be related to the promotion of autophagy, apoptosis and HSP70 expression of myocardium.

Abstract
Abstract
Background
Statins remain a standard treatment for acute coronary syndrome (ACS) patients. We aimed to determine the association between different dosages of in-hospital statins and the prognoses among patients receiving percutaneous coronary intervention (PCI).
Methods
NSTE-ACS patients were retrospectively enrolled from January 2010 to December 2014 from five centres in China. Patients receiving either atorvastatin or rosuvastatin during their hospitalizations were included. All the patients were categorized into high-dose statin group (40mg atorvastatin or 20mg rosuvastatin) or low-dose statin group (20mg atorvastatin or 10mg rosuvastatin). In-hospital events and long-term all-cause death was recorded.
Results
Of the 7,008 patients included in the study, 5,248 received low-dose intensive statin (mean age: 64.28±10.39; female: 25.2%), and 1,760 received high-dose intensive statin (mean age: 63.68±10.59; female: 23.1%). There was no significant difference in in-hospital all-cause death between the two groups (adjusted OR, 1.27; P=0.665). All-cause death was similar between the two groups during the long-term follow-up period (30-day: adjusted HR, 1.28; P=0.571; 3-year: adjusted HR, 0.83; P=0.082). However, there was a robust association between the high-dose statin and the reduction in in-hospital dialysis (adjusted OR, 0.11; P=0.030).
Conclusions
The in-hospital high-dose intensive statin is not associated with lower risks of in-hospital or follow-up all-cause death in NSTE-ACS patients undergoing PCI. Considering the robust beneficial effect of in-hospital dialysis, an individualized high-dose intensive statin can be rational in specified populations.

Abstract
BACKGROUND The prognostic values of the AJCC staging system for gastric cancer (GC-AJCC), the AJCC staging system for gastric neuroendocrine tumours (NET-AJCC) and the European Neuroendocrine Tumor Society (ENETS) system for gastric neuroendocrine carcinoma and mixed adenoneuroendocrine carcinoma (MA)NEC remain controversial. METHODS Data on patients with (MA)NEC from 21 centres in China were analysed. Different staging systems were evaluated by performing Kaplan-Meier survival analysis and calculating the concordance index (C-index) and Akaike information criterion (AIC). Based on three existing systems, a modified staging system (mTNM) was developed. RESULTS A total of 871 patients were included. In the GC-AJCC system, an overlap was noticed for pT2 and pT3 categories. Patients with stage IIIC disease had a similar prognosis to those with stage IV disease. The pT categories of the NET-AJCC system had a lower C-index and higher AIC than those of the other systems. In the ENETS system, there was a low proportion (0·2 per cent) of patients with stage IIIA and a high proportion (67·6 per cent) of stage IIIB disease. The mTNM system adopted the NET-AJCC pT and GC-AJCC pN and pM definitions, and was developed based on the ENETS stage definitions. The proportion of patients in each stage was better distributed and the mTNM system showed improved prognostic performance in predicting overall and disease-free survival. CONCLUSION The mTNM system offers more accurate prognostic value for gastric (MA)NEC than the AJCC or ENETS staging systems.

Abstract
PURPOSE Immune checkpoint inhibitor (ICI) monotherapy and combination regimens are being actively pursued as strategies to improve durable response rates in cancer patients. However, the biology surrounding combination therapies is not well understood and may increase the likelihood of immune-mediated adverse events. Accurate stratification of ICI response by non-invasive PET imaging may help ensure safe therapy management across a wide number of cancer phenotypes. PROCEDURES We have assessed the ability of a fluorine-labelled peptide, [18F]AlF-mNOTA-GZP, targeting granzyme B, to stratify ICI response in two syngeneic models of colon cancer, CT26 and MC38. In vivo tumour uptake of [18F]AlF-mNOTA-GZP following ICI monotherapy, or in combination with PD-1 was characterised and correlated with changes in tumour-associated immune cell populations. RESULTS [18F]AlF-mNOTA-GZP showed good predictive ability and correlated well with changes in tumour-associated T cells, especially CD8+ T cells; however, overall uptake and response to monotherapy or combination therapies was very different in the CT26 and MC38 tumours, likely due to the immunostimulatory environment imbued by the MSI-high phenotype in MC38 tumours. CONCLUSIONS [18F]AlF-mNOTA-GZP uptake correlates well with changes in CD8+ T cell populations and is able to stratify tumour response to a range of ICIs administered as monotherapies or in combination. However, tracer uptake can be significantly affected by preexisting phenotypic abnormalities potentially confusing data interpretation.

Abstract
AIM To investigate the association between anxiety symptoms and the progression from prediabetes to type 2 diabetes. METHODS A sample of 1708 participants aged 31-82 years from the population-based Cooperative Health Research in the Region of Augsburg F4 and the follow-up Cooperative Health Research in the Region of Augsburg FF4 studies was included. Prediabetes was defined as impaired fasting glucose and/or impaired glucose tolerance, and anxiety status was measured by the generalized anxiety disorder-7 questionnaire. Newly diagnosed type 2 diabetes cases were identified after 6.5 years (11 102 person-years) and confirmed by medical records. Multivariate logistic regression analyses were employed to estimate the effect of prediabetes and anxiety on the incidence of type 2 diabetes with different levels of adjustments for potential confounders. The population attributable risk of type 2 diabetes in participants with prediabetes and anxiety was estimated. RESULTS Prediabetes at baseline was prevalent in 247 participants, of whom 77 developed diabetes after follow-up, accounting for a progression rate of 31%. In participants with prediabetes, high anxiety was associated with a 3-fold increased risk of progression to type 2 diabetes in comparison with low anxiety, even after accounting for socio-demographic, lifestyle and metabolic risk factors (OR = 2.82, 95% CI = 0.95-8.37, P = 0.06). A significant proportion of incident type 2 diabetes was attributed to having anxiety in addition to prediabetes (attributable risk proportion: 0.52; 95% CI = 0.004-1.04, P = 0.05). CONCLUSIONS Anxiety symptoms independently increase the progression risk of prediabetes to type 2 diabetes and should be routinely considered alongside the traditional risk factors in people with prediabetes.

Abstract
OBJECTIVE To investigate the correlation between endometrial receptivity with expressions of interleukin-1 (IL-1) and vascular endothelial growth factor (VEGF) in rats with polycystic ovary syndrome (PCOS). MATERIALS AND METHODS A total of 24 female Sprague-Dawley (SD) 21 days old were randomly divided into control group (n=12) and PCOS group (n=12). Rats in the control group were normally raised, and PCOS model was established in rats of the PCOS group. All the rats were sacrificed when they grew to 80 days old. Immunohistochemistry was applied to detect the expressions of IL-1 and VEGF. Western blotting was performed to measure the relative expressions of IL-1 and VEGF proteins. Quantitative Polymerase Chain Reaction (qPCR) was utilized to determine the relative messenger ribonucleic acid (mRNA) expressions of IL-1 and VEGF. Data related to endometrial receptivity were detected. RESULTS The expression levels of IL-1 and VEGF in the PCOS group declined markedly compared with those in the control group, and the differences were statistically significant (p<0.05). PCOS group had notably lower protein expressions of IL-1 and VEGF than the control group, with statistically significant differences (p<0.05). The mRNA expressions of IL-1 and VEGF in PCOS group were significantly lower than those in the control group, displaying statistically significant differences (p<0.05). Compared with that in the control group, the endometrial receptivity of rats in the PCOS group was reduced evidently, and the difference was statistically significant (p<0.05). Both IL-1 and VEGF had positive correlations with the endometrial receptivity. CONCLUSIONS Both IL-1 and VEGF are positively correlated with the endometrial receptivity in the case of PCOS, which can serve as therapeutic targets for PCOS and improve endometrial receptivity in the future.

Abstract
Objective: To explore the related factors of premature acute myocardial infarction(AMI), and to compare the the long-term outcomes in patients with and without premature AMI after percutaneous coronary intervention (PCI). Methods: This study was a prospective cohort study.From January 2013 to December 2013, 10 724 consecutive patients with coronary heart disease undergoing PCI in Fuwai Hospital were enrolled. Among them 1 920 patients with the diagnosis of AMI were divided into two groups: premature AMI (man≤50 years old, woman≤60 years old) and non-premature AMI. The baseline characteristics were collected, and multivariate logistic regression was uesed to analysis the related factors of premature AMI. The clinical outcomes, including the major adverse cardiovascular and cerebrovascular events(MACCE) which was the composite of cardiac death, myocardial infarction, revascularization, stroke and stent thrombosis, as well as bleeding events, during hospitalization, at 2 years and 5 years follow-up were analyzed. Results: A total of 1 920 AMI patiens were included(age was (56.5±11.3) years old),with 1 612(84.0%) males. There were statistically significant differences between the two groups in gender, body mass index, blood lipid, complications, inflammatory markers, etc (all P<0.05). Multivariate logistic regression analysis showed body mass index(OR=1.06, 95%CI 1.01-1.10, P<0.01), triglyceride(OR=1.47, 95%CI 1.14-1.90, P<0.01), serum uric acid level(OR=1.02, 95%CI 1.01-1.04, P<0.01), high density lipoprotein cholesterol level(OR=0.33, 95%CI 0.14-0.78, P=0.01) and history of hypertension(OR=0.72, 95%CI 0.56-0.93, P=0.01) were independent related factors of premature AMI. The incidence of all-cause death and cardiac death were lower during hospitalization, at 2 years and 5 years follow-up in the premature AMI group than in non-premature AMI group(all P<0.05). In the premature AMI group, the incidence of MACCE and stroke was lower, with more bleeding events in 5 years follow-up(all P<0.05). Conclusions: Metabolic abnormalities, including high BMI, high triglyceride level and high serum uric acid, low high-density lipoprotein cholesterol level are the related factor of premature AMI. The incidence of ischemic events in patients with premature AMI is lower, while the incidence of bleeding events is higher than non-premature AMI patients.

Abstract
BACKGROUND AND PURPOSE Anxiety and depression during pregnancy have been associated with an increased risk of adverse neurodevelopmental outcomes in offspring. We aimed to study the in utero effects of maternal anxiety and depression on early brain development. MATERIALS AND METHODS Pregnant women were recruited at ∼36 weeks of gestation for this prospective study. They were assessed for anxiety symptoms by the State-Trait Anxiety Inventory and for depression symptoms by the Beck Depression Inventory, 2nd Edition. After delivery, infant underwent an MR imaging examination of the brain without sedation, including DTI, for evaluation of white matter (WM) development. Infant fractional anisotropy values, a putative marker of WM integrity, were correlated with the mothers' State-Trait Anxiety Inventory and Beck Depression Inventory scores by using both tract-based spatial statistics and ROI methods. RESULTS Thirty-four infants were included in this study. Both maternal State-Anxiety and Trait-Anxiety scores negatively correlated (P < .05, corrected) with fractional anisotropy values in widespread brain WM regions; Beck Depression Inventory scores also negatively correlated (P < .05) with fractional anisotropy values in one cluster in the brain. Further ROI analyses confirmed significant negative correlations between average fractional anisotropy values in ROIs including left and right prefrontal WM, left and right middle frontal gyrus WM, and the fornix, and State-Anxiety (R values, -0.47 to -0.67; P values, .008 to <.001), Trait-Anxiety (R, -0.37 to -0.59; P, .04 to <.001), and Beck Depression Inventory (R values, -0.36 to -0.55; P, .05 to .002) scores. CONCLUSIONS Higher maternal anxiety and depression symptom scores during late pregnancy were associated with lower estimated infant brain WM development, which indicated in utero influences of maternal mental health during pregnancy on the developing brain.

Abstract
OBJECTIVE Demyelinating neurodegenerative diseases are some of the most important neurological diseases that threaten the health of the elderly. Astrocytes (ASTs) play an important role in the regulation of the growth and development of oligodendrocytes (OLs) and oligodendrocyte progenitor cells (OPCs), which participate in remyelination. This study investigated the mechanism by which ASTs promote the proliferation of OPCs via connexin 47 (Cx47) in OPCs. MATERIALS AND METHODS Under direct-contact co-culture conditions, we performed Cx47 siRNA interference in ASTs and OPCs and tested the cell proliferation ability by flow cytometry and with 5-ethynyl-20-deoxyuridine (EdU). We then detected Chi3l1 expression by Western blotting and immunofluorescence. Next, after the addition of exogenous Chi3l1 protein to OPCs under monoculture conditions, we tested the cell proliferation ability by flow cytometry and EdU. RESULTS After siRNA interference with Cx47, the expression of Chi3l1 decreased from 1.10±0.91 to 0.30±0.08, and the proportion of new OPCs decreased from 48.7±3.8% to 28.4±6.6%. Moreover, upon addition of exogenous Chi3l1 protein under OPCs mono-culture conditions, the expression of cyclin D1 increased from 0.68±0.09 to 1.16±0.14, leading to an increased number of OPCs in the S phase, from 7.37±1.38% to 13.55±1.60%. CONCLUSIONS Cx47/Chi3l1 plays an important role in the promotion of OPCs proliferation by ASTs. ASTs can promote the expression of Chi3l1 via Cx47 in OPCs, and then activate the expression of cyclin D1 and regulate the cell cycle of OPCs, thereby promoting cell proliferation. This study provides a new target for the treatment of neurodegenerative diseases.

Abstract
The aim of the research was to evaluate the dynamic changes of early posthatch starvation on residual yolk absorption, synthesis of macronutrients (protein, lipid, and glycogen), and organ development in broiler chicks. A total of 720 1-day-old chicks (Lingnan Yellow) were randomly assigned to 3 treatments: group A (nonfasted), group B (fasting for 24 h after placement), and group C (fasting for 48 h after placement). The trial lasted for 168 h, and water was provided ad libitum all the time. Sampling was performed at 0, 24, 48, 72, 120, and 168 h. Nonfasting (group A) promoted (P < 0.05) the absorption of amino acids, fatty acids, mineral elements, protein, and maternal antibody in the residual yolk of broiler chicks. The concentration of insulin-like growth factor 1 in plasma and the liver was higher (P < 0.05) in group A. Nonfasting enhanced (P < 0.05) the synthesis of protein and glycogen in the breast muscle and liver; the relative weights of the liver, pancreas, and spleen; and body weight, but retarded (P < 0.05) the synthesis of triglyceride in the liver. The results indicated that nonfasting (group A) after placement promoted the absorption of residual yolk and synthesis of protein and glycogen in the breast muscle and liver, whereas early feed deprivation promoted the synthesis of lipid in the liver. Thereby, nonfasting after placement promoted organ development and body growth of broiler chicks.

Abstract
This work studied bacterial community structure and gene function prediction in long-term running of dual graphene modified bioelectrode bioelectrochemical systems (LT D-GM-BE BES, 2 year). The maximum power density of LT D-GM-BE BES was 99.03 ± 3.64 mW/m2, which was 3.66 times of dual control BES (D-C-BE BES), and the transfer resistance of LT GM-BE was just approximately 1/4 of control bioelectrode (C-BE). Proteobacteria and Firmicutes were dominant bacteria in long-term modified bioanode (LT GM-BA, 30.03% and 45.64%), and in long-term modified biocathode (LT GM-BC) was Armatimonadetes (47.14%) in phylum level. The dominant bacteria in LT GM-BA was Clostridium (30.56%), in GM-BC was Chthonomonas (47.14%) in genus level. Gene function related with substrate, energy metabolism and environmental adaptation were enriched. LT GM-BE was tended to enrich dominant bacteria and enrich gene to adapt to micro-environmental changes. This study would provide metagenomics information for long-term running of BES in future.

Abstract
Pseudomonas aeruginosa is a widely distributed non-fermentative Gram-negative opportunistic pathogen that is often responsible for nosocomial infections. Gene interference is a potentially valuable tool for investigating essential genes in P. aeruginosa. To establish a gene interference platform in P. aeruginosa, CRISPR system was used with an inactive Cas9 protein. The CRISPR-dCas9 system was cloned into pHERD20T, a shuttle vector with arabinose inducible promoter, and was further modified to target a regulatory gene prtR that is essential for the viability of P. aeruginosa. Cells expressing the prtR-targeting CRISPR interference (CRISPRi) showed growth defect in an arabinose dose-dependent manner. A high-throughput RNA sequencing analysis of bacterial cells with or without the CRISPRi-mediated prtR inhibition indicated that prtRis a global regulator affecting multiple biological processes. In conclusion, the CRISPR-dCas9-based gene knockdown system has been successfully implemented in P. aeruginosa and demonstrated to be an effective tool in the investigation of essential or difficult-to-inactivate genes in this species.

Abstract
Purpose Although several metal artifact reduction (MAR) algorithms for computed tomography (CT) scanning are commercially available, no quantitative, rigorous, and reproducible method exists for assessing their performance. The lack of assessment methods poses a challenge to regulators, consumers, and industry. We explored a phantom‐based framework for assessing an important aspect of MAR performance: how applying MAR in the presence of metal affects model observer performance at a low‐contrast detectability (LCD) task This work is, to our knowledge, the first model observer–based framework for the evaluation of MAR algorithms in the published literature. Methods We designed a numerical head phantom with metal implants. In order to incorporate an element of randomness, the phantom included a rotatable inset with an inhomogeneous background. We generated simulated projection data for the phantom. We applied two variants of a simple MAR algorithm, sinogram inpainting, to the projection data, that we reconstructed using filtered backprojection. To assess how MAR affected observer performance, we examined the detectability of a signal at the center of a region of interest (ROI) by a channelized Hotelling observer (CHO). As a figure of merit, we used the area under the ROC curve (AUC). Results We used simulation to test our framework on two variants of the MAR technique of sinogram inpainting. We found that our method was able to resolve the difference in two different MAR algorithms’ effect on LCD task performance, as well as the difference in task performances when MAR was applied, vs not. Conclusion We laid out a phantom‐based framework for objective assessment of how MAR impacts low‐contrast detectability, that we tested on two MAR algorithms. Our results demonstrate the importance of testing MAR performance over a range of object and imaging parameters, since applying MAR does not always improve the quality of an image for a given diagnostic task. Our framework is an initial step toward developing a more comprehensive objective assessment method for MAR, which would require developing additional phantoms and methods specific to various clinical applications of MAR, and increasing study efficiency.

Abstract
Background:Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is a group of autoimmune disease that can cause systemic organ damage, including granulomatosis with polyangiitis(GPA), microscopic polyangiitis (MPA), and eosinophilic granulomatosis with polyangiitis(EGPA)[1]. Several observations have showed that the breakdown of immune tolerance was involved in the pathogenesis of AAV [2], furthermore, a single, open and clinical trial demonstrates that IL-2 can be used to treat patients with GPA [3]. But there is still a lack of understanding of the relationship between Th17 / Treg and AAV and evidence for the therapeutic effect of IL-2 on AAV, which needs further exploration.Objectives:We first measured the absolute number of CD4+T subsets in peripheral blood of patients to explore the pathogenesis of AAV, and then investigated the effects of short-term and low-dose recombinant human IL-2 (rhIL-2) on CD4+T subsets of patients to analyze the regulatory effect of IL-2 on AAV.Methods:49 patients with AAV, hospitalized at the Second Hospital of Shanxi Medical University from the May 2016 to the November 2019 were enrolled, including 36 patients who were only received conventional glucocorticoids and DMARDs, and other 13 patients who were not only received these treatments but were also injected subcutaneously rhIL-2(50WIU/day for a 5-day course). 31 age and gender-matched healthy adults were selected as controls. The absolute number of Th17 and Treg cells in peripheral blood of health controls and the patients before and after treatment was detected by flow cytometry.Results:There was significant decreased level of Treg cells in the patients with AAV compared with healthy controls (P<0.001) leading to a higher Th17/Treg ratio in the patients with AAV, but there was no statistically significant in the absolute number of Th17 cells between the patients and healthy controls. After the treatment of short-term and low-dose IL-2, there was a significant increase in the absolute number of Treg cells (P<0.01) leading to a decrease in the ratio of Th17 and Treg (p<0.05).The absolute number of Th17 had a trend towards higher values but was not statistical significance.Conclusion:The difference of Treg cells between the patients and healthy controls suggested that the decreased number of Treg cells failed to control autoimmune inflammatory response contributing to the pathogenesis of AAV. After the treatment of short-term and low-dose rhIL-2, there was a more significant increase in the absolute number of Treg cells showing that IL-2 could selectively stimulate the growth of Treg cells and restore the Treg-mediated immune tolerance in patients with AAV to achieve disease remission.References:[1]Cosmi, L.,Th17 and Treg lymphocytes as cellular biomarkers of disease activity in Granulomatosis with Polyangiitis.Eur J Immunol, 2017.47(4): p. 633-636.[2]Pagnoux, C.,Updates in ANCA-associated vasculitis.Eur J Rheumatol, 2016.3: p. 122-133.[3]Rosenzwajg, M., et al.,Immunological and clinical effects of low-dose interleukin-2 across 11 autoimmune diseases in a single, open clinical trial.Annals of the Rheumatic Diseases, 2019.78(2): p. 209-217.Disclosure of Interests:None declared

Abstract
Background:Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) are a group of multisystem, autoimmune, inflammatory disease characterized by pauci- necrotizing vasculitis affecting small blood vessels. The clinical manifestations of the AAV are diverse and can be confined to one organ, or multiple organs and even life-threatening. However, there has been no specific index for assessing the activity of AAV at diagnosis.Objectives:The aim of this study was to describe the clinical and serological features of patients with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) in eastern China using data from a hospital-based study. And looking for indicators that can predict disease activity.Methods:We retrospectively studied patients with newly diagnosed AAV evaluated from January 1, 2009, to December 31, 2018. In total, 219 patients diagnosed were classified according to the American College of Rheumatology classification criteria and/or revised Chapel Hill 2012 definitions, and their clinical and serological features were evaluated. The association of laboratory data with disease activity was assessed via regression models.Results:Of 219 incident cases of AAV, 37/219 (16.9%) had granulomatosis with polyangiitis (GPA), 172/219 (78.5%) were microscopic polyangiitis (MPA), and 10/219 (4.6%) had eosinophilic granulomatosis with polyangiitis (EGPA). The mean age at diagnosis of patients with GPA were 51.5 years MPA were 61.7 years, and EGPA were 49.8 years, respectively. Patients with MPA were significantly older than GPA and EGPA at diagnosis (p<0.001). ANCAs tested positive in 207 (94.5%) of cases: 167 (80.7%) were MPO-ANCA and 40 (19.3%) were PR3-ANCA. Lung, skin, nervous system symptoms were the most common in EGPA. For GPA, ear–nose–throat (ENT) symptoms and lungs involvement were the most common. Renal and lung involvement occurs most frequently in MPA. In the multivariable logistic regression analysis, higher anti-MPO antibody (149.4 IU/ml), higher hypersensitive c-reactive protein (hs-CRP, 62.5 mg/L), lower hemoglobin (113.5g/L), and higher complement 4 (C4, >0.215 g/L) were proved to be independent risk factors for active disease. Further research showed that C4 had higher sensitivity (70.0%) and specificity (83.4%) than the other three indicators.Conclusion:MPO-ANCA-positive MPA is the most common form of AAV in Chinese patients. Serum C4 concentrations at diagnosis might be a useful biomarker of disease activity in AAV.References:[1]Jennette JC, Falk RJ, Bacon PA, Basu N, Cid MC, Ferrario F, et al. 2012 revised International Chapel Hill Consensus Conference Nomenclature of Vasculitides.Arthritis Rheum2013, 65:1-11.[2]Choi H, Kim Y, Jung SM, Song JJ, Park Y-B, Lee S-W.

Abstract
Background:The disease activity evaluation of Takayasu arteritis (TA) is a critical issue for disease monitoring and treatment. But the previous markers such as Kerr score or ITAS 2010 are not convenient enough.Objectives:We aim to explore novel biomarkers to assess TA disease activity.Methods:This cross-sectional study was based on the East China TA (ECTA) cohort. Demographic characteristics, clinical features, laboratory and imaging results were collected. Complements and their combination with other biomarkers in identifying active disease (Kerr >= 2) group were analyzed. Internal and external validation were employed to confirm the accuracy and stability of the results.Results:519 patients were enrolled, among which 406 cases (72.2%) were identified as active disease. Higher ESR, CRP, platelet, globulin, IgG, IL-6, complement 3 (C3), complement 4 (C4) and median haemolytic complement (CH50) levels were observed in the active disease group. Logistic regression analysis demonstrated that C3 levels [odds ratio [OR] (95%CI): 10.710(1.825 – 62.835), P = 0.009] and CRP [OR (95%CI): 1.041(1.009 – 1.073), P = 0.011] were independently associated with active disease. The cut-off of C3 to identify active TA was 1.085 g/L, with 69.9% sensitivity, 66.7% specificity. Combining the CRP (cut-off, 10.65g/L; sensitivity, 50.7%; specificity, 82.4%) and C3, the sensitivity and specificity to identify the active disease were 85.1% and 55.0% (parallel test), and 35.4% and 94.1% (serial test), respectively. C3 could significantly improve the diagnostic ability of CRP [net reclassification index: OR (95%CI): 1.728 (1.556–1.990), P = 0.000; integrated discrimination index: OR (95%CI): 0.328 (0.224–0.431), P = 0.000]. The accuracy of the 10-fold cross validation of combining CRP with C3 was over 75%, and the accuracy of the external validation with 53 TA cases was 72.73%.Conclusion:C3 could reflect the disease activity of TA, and combining CRP with C3 could significantly improve the disease activity evaluation in TA.References:[1]Ma J, Luo X, Wu Q, Chen Z, Kou L, Wang H.

Abstract
Background:The incidence of renal artery stenosis in Takayasu arteritis (TA) was 20%–60% according to previous reports. The specific characteristics of patients with TA-related renal artery stenosis and the effect of revascularization procedures on prognosis have not been fully investigated.Objectives:To investigate the characteristics of patients with TA-related renal artery stenosis and identify the predictors of medium-term adverse outcomes.Methods:Data for 567 patients registered in a large prospective observational cohort-the East China Takayasu arteritis cohort-up to April 30, 2019, were retrospectively analyzed.Results:Renal artery stenosis was confirmed in 172/567 (30.34%) patients, with left renal artery involvement seen in 73/172 (42.44%) patients. Renal insufficiency at presentation (HR = 2.37, 95% CI: 1.76-15.83, p = 0.03), bilateral renal artery involvement (HR = 6.95, 95% CI: 1.18-21.55, p = 0.01), and severe (>75%) stenosis (HR = 4.75, 95% CI 1.08-11.33, p = 0.05) were predictors of adverse outcomes. Revascularization was performed for 46/172 (26.74%) patients. Patients without preoperative treatment had higher rate of restenosis (44.44% vs. 15.79%, p < 0.01) and hypertension deterioration (25.93% vs. 10.53%, p < 0.01) after the procedure. Non-receipt of preoperative treatment (HR = 6.5, 95% CI: 1.77-32.98, p = 0.04) and active disease at revascularization (HR = 4.21, 95% CI 2.01-21.44, p = 0.04) were independent predictors of adverse outcomes after revascularization.Conclusion:Patients with uncontrolled or worsening hypertension or/and renal function may benefit from revascularization. Those who have received preoperative treatment may have more favorable revascularization outcomes. Prognosis appears to be poorer for patients with renal insufficiency at presentation, bilateral artery involvement, and severe stenosis.References:[1]Watanabe Y, Miyata T, Tanemoto K.

Abstract
Background:Takayasu’s arteritis (TA) is a chronic inflammatory disease characterized with macrophages infiltration. During active stage, aorta adventitial fibroblasts (AAFs) proliferate excessively and produce numerous pro-inflammatory factors in the adventitia, which is the main target of TA therapy. Monocyte chemokine CCL2 may contribute to the infiltration of macrophages in TA arteries[1]but whether with relationship with HSP65, an antigen of Mycobacterium tuberculosis (M. TB) which might involve in the pathogenesis of TA[2]and activate AAFs to produce inflammatory factors, has not been reported. The treatment of TA is full of difficulties and contradictions[3]. Curcumin is a traditional Chinese medicine with anti-inflammatory effect[4], whether it is effective on TA and the underlying mechanism remains unclear.Objectives:To explore the mechanism of TA inflammation triggered by M. TB associated antigen HSP65 activating AAFs, as well as the therapeutic value of curcumin in the initiation and development of TA.Methods:We first verified high HSP65 expression in aortic adventitia of TA patients by IHC. mRNA-seq was used to profile DEGs between AAFs stimulated by HSP65 with or without pretreated with curcumin, and AAFs without any treatment. Then the key chemokine CCL2 screened by mRNA-seq was detected in the adventitia of TA aorta, and its correlation with HSP65 expression was analyzed by double-labelled IF. Subsequently, we explored how HSP65 affected the production of inflammatory factors by AAFs at cellular level and its related signal pathway. Simultaneously, we explored whether curcumin could hinder this process. and verified the effect of curcumin on serum CCL2 level in patients with TA. Finally, serum CCL2 and other inflammation indicators of TA patients at baseline and after 3 months treatment by curcumin were determined.Results:HSP65 was highly expressed in the adventitia of TA arteries. DEGs analysis showed a key role of CCL2. The expression of CCL2 in adventitia of TA arteries was significantly higher than healthy subjects, and was correlated with HSP65. HSP65 facilitated the production of CCL2, IL-6 and IL-1β by AAFs via activating TLR4-JAK2/AKT/STAT3 pathway, among which the change of CCL2 was the most remarkable. Curcumin reversed the upregulation of CCL2 induced by HSP65 in vitro, which was more obvious than that of MTX and tofacitinib. Finally, curcumin significantly downregulated the level of serum CCL2 of TA patients.Conclusion:HSP65 initiates and promotes inflammation of TA by upregulated CCL2 in AAFs through JAK/AKT/STAT3 pathway, while curcumin can reverse this process and slow down the initiation and development of TA.References:[1]L, A., J, H., A, M., G, G. & Z, A.

Abstract
Background:Takayasu arteritis (TA) is a chronic, granulomatous large-vessel vasculitis. It involves the aorta and its main branches predominantly, and leads to vascular thickness, stenosis and occlusion [1]. Besides the aorta and its branches, pulmonary arteries (PAs) are involved in TA. PAs have been reported to be involved in 6.9% to 80% of TA patients from different populations [2-3].Objectives:We investigated the clinical characteristics, pulmonary parenchymal features and cardiac functions in TA patients with PA involvement by combining multiple imaging modalities (MRA, CTA, PET-CT, lung VQ scan, echocardiography and high-resolution computed tomography (HRCT)). Our aim was to elicit better understanding of TA patients with PA involvement to aid rational treatment for these patients and improve their prognosis.Methods:We enrolled 216 patients with TA from a large prospective cohort. PAI was assessed in each patient based on data from magnetic resonance angiography/computed tomography angiography. Pulmonary hypertension, cardiac function, and pulmonary parenchymal abnormalities were evaluated further in patients with PAI based on echocardiography, New York Heart Association Functional Classification and pulmonary computed tomography, respectively. These abnormalities related to PAI were followed up to evaluate treatment effects.Results:PAI was detected in 56/216 (25.93%) patients, which involved the pulmonary trunk, main PAs and small vessels in the lungs. Among patients with PAI, 28 (50%) patients were accompanied by pulmonary hypertension, which was graded as ‘severe’ in 9 (16.07%), ‘moderate’ in 10 (17.86%) and mild in 9 (16.07%). Forty (71.43%) patients had cardiac insufficiency (IV: 6, 10.71%; III: 20, 35.71%; II: 14, 25.00%). Furthermore, 21 (37.50%) patients presented with abnormal parenchymal features in the area corresponding to PAI (e.g., the mosaic sign, infarction, bronchiectasis). During follow-up, two patients died due to abrupt pulmonary thrombosis. In the remaining patients, the abnormalities mentioned above improved partially after routine treatment.Conclusion:PA involvement is very common in TA patients. Physicians should be alerted to PA involvement even if obvious pulmonary symptoms are absent because they can cause PH, cardiac insufficiency as well as pulmonary parenchymal lesions, which will worsen the prognosis.References:[1]M.L.F.

Abstract
Major histocompatibility complex class I (MHC-I)-dependent inhibitory receptors on natural killer (NK) cells have been found to contribute to NK cell dysfunction in hepatocellular carcinoma (HCC). However, the roles of MHC-I-independent inhibitory receptors on NK cells in HCC remain poorly defined. In this study, we analyzed the expression of the MHC-I-independent inhibitory receptors sialic acid-binding immunoglobulin-like lectin (Siglec)-7 and Siglec-9 on NK cells by analyzing the peripheral blood of 35 HCC patients and 63 healthy donors. We observed that HCC patients had lower frequencies and total numbers of NK cells in the peripheral blood. Importantly, both the expression levels of Siglec-7 on NK cells and the frequencies of Siglec-7+ NK cells were significantly reduced in HCC patients, which was accompanied by a decrease in activating receptor and an increase in inhibitory receptor expression on NK cells. Moreover, Siglec-7+ NK cells expressed higher levels of activating receptors and displayed stronger effector functions, compared with Siglec-7- NK cells. Our findings demonstrate for the first time that reduced Siglec-7 expression predicts NK cell dysfunction in HCC patients, suggesting that Siglec-7 may be a potential marker of functional NK cell subset in HCC patients.

Abstract
Chronic obstructive pulmonary disease (COPD), characterized by chronic inflammation, is a recognized global health crisis. Sialic acid-binding immunoglobulin-like lectin 1 (siglec1 or CD169), mainly expressed in macrophages and dendritic cells, is markedly upregulated after encountering pathogens or under acute/chronic inflammation conditions. However, it is rarely reported that whether siglec1 plays a role in the development of COPD. In this study, we found that siglec1 had higher expression in the lungs from COPD rats and in peripheral blood mononuclear cells (PBMCs) from COPD patients. Knockdown of siglec1 in vivo and in vitro dramatically decreased pro-inflammatory cytokines production in pulmonary macrophages and alleviated pulmonary inflammatory responses in COPD rats as well as inactivated nuclear factor kappa B (NF-κB) signaling. In addition, we identified a new microRNA, miR-195-5p, which has never explored in COPD, was lower expressed in COPD rats and PBMC of COPD patients, and could negatively modulate siglec1 expression in macrophages. Moreover, overexpression of miR-195-5p via miR-195-5p mimics in vitro and in vivo could significantly alleviate pro-inflammatory cytokines production in pulmonary macrophages and pulmonary inflammatory responses in COPD rats. Together, our findings suggested that miR-195-5p inhibited the development of COPD via targeting siglec1, which might become a therapeutic target to improve COPD.

Abstract
OBJECTIVES To explore the causes of cochlear implantation and reference function of old electrical stimulation electrode in cochlear reimplantation in children. METHODS The causes, surgical methods and problems found during the operations of 24 cases of cochlear reimplantation in Henan Children's Hospital from June 2016 to April 2018 were analyzed. RESULTS Twenty-three cases successfully completed the surgery of cochlear-reimplantation, and the remaining one case had approximately 1/3 of the anterior end of the residual cochlear electrode due to high resistance at the time of withdrawal of the electrodes. The causes of re-implantation were implant equipment failure (eleven cases), elevated impedance values of all electrodes after head trauma (two cases), and implant prolapse together with the electrode caused by a traffic accident (one case). CONCLUSION The old stimulus electrode can provide an important reference to reduce the risk of operation and ensure the success of the reoperation.

Abstract
From November to December of 2018, twenty 65-year-old or older women patients with knee osteoarthritis were recruited from the Department of Physical Therapy, the First Affiliated Hospital of Anhui Medical University. Meanwhile, twenty healthy 65-year-old or older women were recruited from the local community. The results showed that the knee contact angle of the patient group was more flexed (P=0.040), and the minimum angle of the knee joint increased (P=0.008) during the stance period compared to the healthy group. However, there was no significant difference in the maximum contact angle between the angle of hip and ankle joints. In addition, the tibialis anterior muscle of the patients was significantly smaller than the healthy group (P=0.023). Therefore, knee osteoarthritis could change the gait and muscle activity of older women, especially the knee joint.

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
Objective: To analyze the association between plasma high-density lipoprotein cholesterol (HDL-C) levels and the severity of coronary artery disease, and to evaluate the impact of HDL-C levels on long-term outcomes in patients underwent percutaneous coronary intervention (PCI). Methods: A total of 10 458 consecutive patients underwent PCI from January 2013 to December 2013 at Fuwai hospital were enrolled in this study. Patients were divided into three groups according to HDL-C tertiles: low HDL-C group (HDL-C≤0.89 mmol/L, n=3 525), median HDL-C group (HDL-C>0.89-1.11 mmol/L, n=3 570) and high HDL-C group (HDL-C>1.11 mmol/L, n=3 363). SYNTAX score was used to evaluate the severity of coronary artery disease, linear regression was used to analyze the relationship of HDL-C and SYNTAX score. Kaplan-Meier survival analysis was used to compare the outcomes among the three groups. Multivariate Cox regression was used to define the potential associations of HDL-C and outcomes. Results: The HDL-C level was (1.03±0.28) mmol/L and the SYNTAX score was 11.7±8.1. Patients were older, proportion of female, stable angina pectoris, successful PCI and left ventricular eject fraction value were higher, while incidence of diabetes mellitus was lower, hyperlipidemia, old myocardial infraction, smoking history and left main and three vessels disease were lower in high HDL-C group (all P<0.05). Patients in high HDL-C group also had the lowest SYNTAX score (12.2±8.4 vs. 11.7±8.1 vs. 11.2±7.8, P<0.001). Both univariate and multivariate linear regression analysis showed that HDL-C was negatively associated with SYNTAX score, e.g. Univariate analysis: β=-0.046, P<0.001; Multivariate analysis: β=-0.058, P=0.001. And 10 400 (99.4%) patients completed 2-year follow up. At 2-year follow-up, there were no difference in all-cause death, cardiac death, myocardial infarction, revascularization, stroke, major adverse cardiovascular and cerebral events (MACCE) and stent thrombosis among three groups (P for trend>0.05), while patient in high HDL-C group experienced the highest BARC type 2 bleeding events (P for trend=0.018). Multivariate Cox regression analysis showed that HDL-C level was not an independent risk factor of 2-year adverse ischemia events (P>0.05) and 2-year bleeding events (P>0.05). Conclusion: In patients underwent PCI, plasma HDL-C level is negatively associated with SYNTAX score, but not an independent risk factor of ischemic and bleeding events post PCI.

Abstract
In February 2018, a 67-year-old male patient with infected abdominal aortic aneurysm was admitted to the Department of Vascular Surgery of Yantai Yuhuangding Hospital Affiliated to Qingdao University Medical College. After admission, abdominal aortic endovascular exclusion surgery, right iliac artery-double femoral artery vascular bypass+ infected abdominal aortic aneurysmectomy+ stent removal surgery, and active anti-infective treatment were performed in the department of vascular surgery. Seven days after the vascular prosthesis bypass surgery, the surface skin of the vascular prosthesis of the patient was red and swollen, and there was a purulent discharge, which was diagnosed as poor healing of sinus of vascular prosthesis. Surgeons of our department and the department of vascular surgery performed incision and debridement of sinus of vascular prosthesis+ vacuum sealing drainage (VSD) in the early stage under local anesthesia. After the local infection was controlled and wound blood supply was improved, stage Ⅱ surgery of resection of sinus of vascular prosthesis+ vascular prosthesis partial diversion+ local flap propulsion under general anesthesia was performed. The incision healed well after surgery, and the patient was discharged smoothly. During the follow-up of 6 months, the patient's flap was in good shape, and the wound was healed. This case prompts that after the diagnosis of infected abdominal aortic aneurysm vascular sinus poor healing, we can actively open the infected sinus, use VSD technology to treat granulation wounds, then divert the implanted vascular prosthesis to prepare fresh local flap which covers the vascular prosthesis, and use new silver ion dressing to cover the wounds, thus achieving satisfactory results.

Abstract
The welfare and healthy growth of poultry under intensive feeding conditions are closely related to their living environment. In spring, the air quality considerably decreases due to reduced ventilation and aeration in cage systems, which influences the meat quality and health of broilers during normal growth stages. In this study, we analyzed the airborne bacterial communities in PM2.5 and PM10 in cage broiler houses at different broiler growth stages under intensive rearing conditions based on the high-throughput 16S rDNA sequencing technique. Our results revealed that PM2.5, PM10 and airborne microbes gradually increased during the broiler growth cycle in poultry houses. Some potential or opportunistic pathogens, including Acinetobacter, Pseudomonas, Enterococcus, Microbacterium, etc., were found in the broiler houses at different growth stages. Our study evaluated variations in the microbial communities in PM2.5 and PM10 and potential opportunistic pathogens during the growth cycle of broilers in poultry houses in the spring. Our findings may provide a basis for developing technologies for air quality control in caged poultry houses.

Abstract
AIMS The aim of this study is to investigate Streptococcus suis strains present in Jiangsu province, China. METHODS AND RESULTS In all, 1650 nasal and anal swab samples and 100 tonsils were collected from clinically healthy swine. Culture characteristics, colony morphology and PCR-based analysis of the glutamate dehydrogenase (gdh) gene were performed for S. suis identification, and eight isolates were confirmed to be S. suis. The isolates serogroups were identified by agglutinating test, including 4, 7, 3, 5 and 8. Gene profiling by PCR showed that the manN, purD, orf2, gdh genes were conserved among the isolates and that 50% of the isolates carried dltA, pgdA, srtA and sspA. Antimicrobial susceptibility test showed the isolates displayed resistance to clindamycin, erythromycin, tetracycline, penicillin G, vancomycin and linezolid; while none was resistant to chloramphenicol, multi-drug resistance was seen in most of the isolates. Finally, the LD50 (assessed by zebrafish) of isolates RD105 was 2·6431 × 105 and HA24 was 7·1198 × 106 , which showed RD105 more virulent and was consistent with the results of virulence factor identification. CONCLUSIONS There is a very low proportion of S. suis in the healthy pigs. The virulence factors were related to pathogenicity. Bacteria in Nantong possess greater virulence potential than those in Huaian. SIGNIFICANCE AND IMPACT OF THE STUDY Systematic investigation of S. suis provided the most basic theoretical support for the prevention and control of swine streptococcosis.

Abstract
The study aimed to investigate whether sulforaphane (SFN) protects against angiotensin II (Ang II)-mediated human umbilical vein endothelial cell (HUVEC) injury. Ang II treatment decreased HUVEC viability, increased cell apoptosis, decreased mitochondria membrane potential (MMP), impaired cytochrome c release, activated caspase 3/9, and induced reactive oxygen species (ROS) production, and nicotinamide adenine dinucleotide phosphate oxidase activity. Moreover, SFN treatment blunted Ang II-stimulated oxidative stress and mitochondria-related apoptosis in HUVECs. The ROS scavenger N-acetyl-l-cysteine reduced Ang II-induced oxidative stress and apoptosis, indicating that ROS generation is involved in the Ang II-induced mitochondria-mediated apoptotic pathway. SFN induced nuclear factor erythroid 2 (Nrf2) activation and expression in Ang II-stimulated HUVECs. Downregulation of Nrf2 expression by a target-specific siRNA revealed an Nrf2-dependent effect on the SFN-mediated attenuation of Ang II-induced apoptosis in HUVECs. Pretreatment with brusatol, an Nrf2-specific inhibitor, reversed the protective effects of SFN on Ang II-induced HUVEC injury. SFN treatment protected HUVECs from Ang II-induced damage by decreasing oxidative stress and ameliorating mitochondrial injury.

Abstract
WSL8 encoding a deoxyribonucleoside kinase (dNK) that catalyzes the first step in the salvage pathway of nucleotide synthesis plays an important role in early chloroplast development in rice. The chloroplast is an organelle that converts light energy into chemical energy; therefore, the normal differentiation and development of chloroplast are pivotal for plant survival. Deoxyribonucleoside kinases (dNKs) play an important role in the salvage pathway of nucleotides. However, the relationship between dNKs and chloroplast development remains elusive. Here, we identified a white stripe leaf 8 (wsl8) mutant that exhibited a white stripe leaf phenotype at seedling stage (before the four-leaf stage). The mutant showed a significantly lower chlorophyll content and defective chloroplast morphology, whereas higher reactive oxygen species than the wild type. As the leaf developed, the chlorotic mutant plants gradually turned green, accompanied by the restoration in chlorophyll accumulation and chloroplast ultrastructure. Map-based cloning revealed that WSL8 encodes a dNK on chromosome 5. Compared with the wild type, a C-to-G single base substitution occurred in the wsl8 mutant, which caused a missense mutation (Leu 349 Val) and significantly reduced dNK enzyme activity. A subcellular localization experiment showed the WSL8 protein was targeted in the chloroplast and its transcripts were expressed in various tissues, with more abundance in young leaves and nodes. Ribosome and RNA-sequencing analysis indicated that some components and genes related to ribosome biosynthesis were down-regulated in the mutant. An exogenous feeding experiment suggested that the WSL8 performed the enzymic activity of thymidine kinase, especially functioning in the salvage synthesis of thymidine monophosphate. Our results highlight that the salvage pathway mediated by the dNK is essential for early chloroplast development in rice.

Abstract
There has been a recent surge of interest and progress in creating subwavelength free-space optical potentials for ultracold atoms. A key open question is whether geometric potentials, which are repulsive and ubiquitous in the creation of subwavelength free-space potentials, forbid the creation of narrow traps with long lifetimes. Here, we show that it is possible to create such traps. We propose two schemes for realizing subwavelength traps and demonstrate their superiority over existing proposals. We analyze the lifetime of atoms in such traps and show that long-lived bound states are possible. This work allows for subwavelength control and manipulation of ultracold matter, with applications in quantum chemistry and quantum simulation.

Abstract
Accumulating evidence has supported an increased risk of osteoporotic fracture in postmenopausal women and elderly men diagnosed with diabetes mellitus. However, it is not uncommon for young and middle-aged male patients diagnosed with type 2 diabetes mellitus (T2DM) to suffer from osteopenia or osteoporosis. Few studies focused on this population group are available. The aim of this study is to evaluate bone metabolic status and investigate the influence of T2DM on bone metabolism in 30-50-year-old men. Anthropometric assessment and blood samples were obtained from 160 patients with T2DM and 69 nondiabetic volunteers. Serum parathyroid hormone (PTH) and bone turnover markers (BTMs), including serum procollagen type I N-terminal peptide (PINP), osteocalcin (OC), and β-cross-linked C-telopeptide of type I collagen (β-CTX), were analysed. No significant differences were observed based on age, body mass index, systolic blood pressure, serum calcium, phosphorus, creatinine, total protein, and albumin levels when comparing T2DM and control groups. Fasting blood glucose, HbA1c, triglyceride (TG), total cholesterol, and low-density lipoprotein cholesterol were significantly increased, while high-density lipoprotein cholesterol was significantly decreased in the T2DM group. Compared with controls, diabetic patients showed lower serum PINP, OC, and PTH levels, whereas serum β-CTX levels were similar between the two groups. Moreover, HbA1c levels were positively correlated with PINP and inversely associated with PTH levels. TG levels were negatively correlated with OC or β-CTX levels. Furthermore, multiple linear regression revealed a positive correlation between HbA1c and PINP levels. These results also revealed a negative association between HbA1c and PTH, and between TG and OC levels, even after adjusting for expected confounder factors. Collectively, these findings indicated that young and middle-aged male patients with T2DM showed a lower turnover state resulting from bone formation inhibition. Glucose and lipid metabolic disorders may affect bone formation through different pathways.

Abstract
Abstract With the development of new technologies, such as whole genome sequencing and big data, many countries have constructed large cohorts as strategic resources for precision medicine study. Related studies have significantly promoted research progress in many fields, such as medicine and biology, creating the genetic testing industry. In the forensic field, characterization technologies for features, such as biogeographic ancestry, genetic genealogy and physical appearance have emerged and developed rapidly. Compared with traditional forensic DNA technology, the new technology can search for characteristics and provide clues, quickly becoming an important means to solve difficult cases such as cold cases and accumulated cases. This paper briefly reviews the current status of the construction of large cohorts at home and abroad, and the research progress of forensic molecular phenotyping in the context of precision medicine in the context of precision medicine.

Abstract Genetic markers, such as single nucleotide polymorphism (SNP), insertion/deletion (InDel), were discovered and widely used with the development of whole genome sequencing and bioinformatics technology. The origin and genetic structure of the modern population had been gradually revealed from the perspective of genetics. The study on biogeographic ancestry inference in the field of forensic genetics emerged and developed rapidly, providing clues and scientific basis for the determination of investigation direction and for the narrow of the scope of investigation in the process of case investigation. This paper briefly reviews the research progress, inference methods and development trends of DNA ancestry inference technology.
