Abstract
Abstract Gardenia jasminoides Ellis is a Chinese herbal medicine with medicinal and economic value, but its mechanism of response to waterlogging stress remains unclear. In this study, the “double pots method” was used to simulate the waterlogging stress of Gardenia jasminoides Ellis to explore its physiological and transcriptomic response mechanism. We found no significant damage to Gardenia jasminoides Ellis membrane lipid during stress. POD played a vital antioxidant role, KEGG enrichment showed that secondary metabolites such as flavonoids might also play an antioxidant role, and PRO played a significant osmotic adjustment. Endogenous hormones regulate the Gardenia jasminoides Ellis's growth and development and play a role in signal transduction. Among them, light waterlogging stress is delayed. At the same time, there were 19631, 23693, and 15045 differentially expressed genes on the 5th, 10d, and 15d of Gardenia jasminoides Ellis under waterlogging stress. These genes were closely associated with the proteasome, endopeptidase, ribosome, MAPK signal transduction, and endogenous hormone signal transduction, plant-pathogen interaction and phenylpropanoid biosynthesis and other physiological and metabolic pathways, which regulate the turnover and transportation of protein, the reinforcement and adhesion of cell walls, the induction of stomatal closure, allergic reactions, defense reactions, leaf movements and others. It also can absorb ultraviolet rays to reduce the generation of oxygen free radicals, change the way of energy utilization and adjust the osmotic pressure of plant cells.

Abstract
Objective: To investigate the efficacy of neoadjuvant therapy (NAT) on HER2-positive breast cancer and to analyze their clinicopathological features. Methods: A total of 480 cases of HER2-positive breast cancer who received neoadjuvant therapy (NAT), diagnosed at the Department of Pathology of Fudan University Shanghai Cancer Center from 2015 to 2020, were retrospectively identified. Clinicopathological parameters such as age, tumor size, molecular subtype, type of targeted therapy, Ki-67 proliferation index, ER and HER2 immunohistochemical expression, and HER2 amplification status were analyzed to correlate with the efficacy of NAT. Results: Among 480 patients with HER2-positive breast cancer, 209 achieved pathology complete response (pCR) after NAT, with a pCR rate of 43.5%. Of all the cases,457 patients received chemotherapy plus trastuzumab and 23 patients received chemotherapy with trastuzumab and pertuzumab. A total of 198 cases (43.3%) achieved pCR in patients with chemotherapy plus trastuzumab, and 11 cases (47.8%) achieved pCR in patients with chemotherapy plus trastuzumab and pertuzumab. The pCR rate in the latter group was higher, but there was no statistical significance. The results showed that the pCR rate of IHC-HER2 3+patients (49%) was significantly higher than that of IHC-HER2 2+patients (26.1%, P<0.001). The higher the mean HER2 copy number in the FISH assay, the higher the pCR rate was achieved. The expression level of ER was inversely correlated with the efficacy of NAT, and the pCR rate in the ER-positive group (28.2%) was significantly lower than that in the ER-negative group (55.8%, P<0.001). The pCR rate (29.1%) of patients with luminal B type was lower than that of HER2 overexpression type (55.8%, P<0.001). In addition, higher Ki-67 proliferation index was associated with higher pCR rate (P<0.001). The pCR rate was the highest in the tumor ≤2 cm group (57.7%), while the pCR rate in the tumor >5 cm group was the lowest (31.1%). The difference between the groups was significant (P=0.005). Conclusions: HER2 copy numbers, HER2 immunohistochemical expression level, molecular subtype, ER expression level and Ki-67 proliferation index are significantly associated with pCR after NAT. In addition, fluorescence in situ hybridization results, HER2/CEP17 ratio and tumor size could also significantly affect the efficacy of NAT.

Abstract
Objective: This study aimed to explore the application of interaction-dependent fucosyl-biotinylation (FucoID), a chemical biology-based proximity labeling technique, in capturing tumor antigen-specific T cells and its clinical value in chronic myelogenous leukemia (CML) . Methods: Flow cytometry and fluorescence microscopy were employed to evaluate the experimental parameters for FucoID in CML. Peripheral blood samples were obtained from 14 newly diagnosed CML patients in the chronic phase. These samples underwent flow cytometry-based sorting and were subsequently labeled with FucoID to facilitate the isolation of tumor cells and T cells, followed by the immunophenotypic identification of tumor antigen-specific T cells. Finally, the diagnostic and therapeutic potential of FucoID in CML was assessed. Results: Initially, the experimental parameters for FucoID in CML were established. The proportion of CD3(+) T cells in patients was (8.96±6.47) %, exhibiting a marked decrease compared with that in healthy individuals at (38.89±22.62) %. The proportion of tumor-specific antigen-reactive T cells was (3.34±4.49) %, which demonstrated interpatient variability. In addition, the proportion of tumor-specific antigen-active T cells in CD4(+) T cells was (3.95±1.72) %, which was generally lower than the proportion in CD8(+) T cells at (5.68±2.18) %. Compared with those in tumor-specific antigen-nonreactive T cells, CCR7(-)CD45RA(-) effector memory T cells and CCR7(-)CD45RA(+) effector T cells were highly enriched in tumor-specific antigen-reactive T cells. Moreover, the intensity of tumor immune reactivity in patients exhibited a significant correlation with white blood cell count (WBC) and hemoglobin (HGB) levels in peripheral blood, while no such correlation was observed with other clinical baseline characteristics. Conclusion: The combination of FucoID and flow cytometry enables the rapid identification and isolation of tumor antigen-specific T cells in CML. The successful application of this method in CML and the implications of our findings suggest its potential clinical value in the field of hematologic malignancies.

Abstract
The prevalence of periodontitis is increasing with the aging of the global population. Periodontitis has been suggested to accelerate aging and increase mortality. The present nationwide prospective cohort study aimed to determine whether periodontitis could modify the association of biological aging with all-cause and cause-specific mortality in middle-aged and older adults. Participants ≥40 y of age from the Third National Health and Nutrition Examination Survey (NHANES III) were included (n = 6,272). Phenotypic age acceleration (PhenoAgeAccel) was used to evaluate the biological aging process. Moderate/severe periodontitis was defined using a half-reduced Centers for Disease Control and Prevention and American Academy of Periodontology case definition. Multivariable Cox proportional hazard regression was conducted to estimate the association between PhenoAgeAccel and mortality risk, followed by effect modification analysis to test whether periodontitis modified the association. During a median follow-up of 24.5 y, 3,600 (57.4%) deaths occurred. The positive relationships between PhenoAgeAccel and all-cause and cause-specific mortality were nonlinear. After adjusting for potential confounders, the highest quartile of PhenoAgeAccel was associated with increased all-cause mortality in individuals with no/mild periodontitis (hazard ratio for Q4 vs. Q1 [HRQ4vs.Q1] = 1.789; 95% confidence interval [CI], 1.541-2.076). In contrast, the association was enhanced in patients with moderate/severe periodontitis (HRQ4vs.Q1 = 2.446 [2.100-2.850]). Periodontal status significantly modified the association between PhenoAgeAccel and all-cause mortality (P for interaction = 0.012). In subgroup analyses, the modifying effect of periodontitis was observed in middle-aged adults (40-59 y), females, and non-Hispanic Whites. Although cause-specific mortality showed a similar trend, the PhenoAgeAccel × periodontitis interaction did not reach statistical significance. In conclusion, periodontitis might enhance the association of biological aging with all-cause mortality in middle-aged and older adults. Hence, maintaining and enhancing periodontal health is expected to become an intervention to slow aging and extend life span.

Abstract
Objective: To investigate the role of Maresin1 (MaR1) in hepatic ischemia-reperfusion injury (HIRI). Methods: The HIRI model was established and randomly divided into a sham operation group (Sham group), an ischemia-reperfusion group (IR group), and a MaR1 ischemia-reperfusion group (MaR1+IR group). MaR1 80ng was intravenously injected into each mouse's tail veins 0.5h before anesthesia. The left and middle hepatic lobe arteries and portal veins were opened and clamped. The blood supply was restored after 1h of ischemia. After 6h of reperfusion, the mice were sacrificed to collect blood and liver tissue samples. The Sham's group abdominal wall was only opened and closed. RAW267.4 macrophages were administered with MaR1 50ng/ml 0.5h before hypoxia, followed by hypoxia for 8h and reoxygenation for 2h, and were divided into the control group, the hypoxia-reoxygenation group (HR group), the MaR1 hypoxia-reoxygenation group (MaR1 + HR group), the Z-DEVD-FMK hypoxia-reoxygenation group (HR+Z group), the MaR1 + Z-DEVD-FMK hypoxia-reoxygenation group (MaR1 + HR + Z group), and the Con group without any treatment. Cells and the supernatant above them were collected. One-way analysis of variance was used for inter-group comparisons, and the LSD-t test was used for pairwise comparisons. Results: Compared with the Sham group, the levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), interleukin (IL)-1β, and IL-18 in the IR group were significantly higher (P < 0.05), with remarkable pathological changes, while the level in the MaR1 + IR group was lower than before (P < 0.05), and the pathological changes were alleviated. Compared with the Con group, the HR group had higher levels of IL-1β and IL-18 (P < 0.05), while the MaR1 + HR group had lower levels of IL-1β and IL-18 (P < 0.05). Western blot showed that the expressions of caspase-3, GSDME, and GSDME-N were significantly higher in the HR group and IR group than in the other groups; however, the expression was lower following MaR1 pretreatment. The Z-DEVD-FMK exploration mechanism was inhibited by the expression of caspase-3 in HIRI when using MaR1. Compared with the HR group, the IL-1β and IL-18 levels and the expressions of caspase-3, GSDME, and GSDME-N in the HR + Z group were decreased (P < 0.05), while the expression of nuclear factor κB was increased, but following MaR1 pretreatment, nuclear factor κB was decreased. There was no significant difference in the results between the MaR1 + H/R group and the MaR1 + H/R + Z group (P > 0.05). Conclusion: MaR1 alleviates HIRI by inhibiting NF-κB activation and caspase-3/GSDME-mediated inflammatory responses.

Abstract
To explore the digital manufacturing process of distal extension removable partial denture. From November 2021 to December 2022, 12 patients (7 males and 5 females) with free-ending situation were selected from the Department of Prosthodontics, School of Stomatology, The Fourth Military Medical University. Three-dimensional model of the relationship between alveolar ridge and jaw position was obtained by intraoral scanning technique. After routine design, manufacturing and try-in of metal framework for removable partial denture, the metal framework was located in the mouth and scanned again to obtain the composite model of dentition, alveolar ridge and metal framework. The free-end modified model is obtained by merging the digital model of free-end alveolar ridge with the virtual model with the metal framework. The three-dimensional model of artificial dentition, and base plate was designed on the free-end modified model, and the resin model were made by digital milling technology. The removable partial denture was made by accurately positioning the artificial dentition and base plate, bonding metal framework with injection resin, grinding and polishing the artificial dentition and resin base. Compared with the design data after clinical trial, the results showed that there was an error of 0.4-1.0 mm and an error of 0.03-0.10 mm in the connection between the resin base of artificial dentition and the connecting rod of the in-place bolt and the connection between artificial dentition and resin base. After denturen delivery, only 2 patients needed grinding adjustment in follow-up visit due to tenderness, and the rest patients did not find any discomfort. The digital fabrication process of removable partial denture used in this study can basically solve the problems of digital fabrication of free-end modified model and assembly of artificial dentition with resin base and metal framework.

Abstract
Objective: To investigate the clinical features and long-term prognostic factors of diabetic patients with low or intermediate complexity coronary artery disease (CAD) post percutaneous coronary intervention (PCI). Methods: This was a prospective, single-centre observational study. Consecutive diabetic patients with SYNTAX score (SS)≤32 undergoing PCI between January and December 2013 in Fuwai hospital were included in this analysis. The patients were divided into two groups based on SS, namely SS≤22 group and SS 23-32 group. Multivariate Cox regression analysis was performed to identify independent factors related to poor 5-year prognosis. The primary outcomes were cardiac death and recurrent myocardial infarction, the secondary outcomes were all cause death and revascularization. Results: Of the 3 899 patients included in the study, 2 888 were men (74.1%); mean age was 59.4±9.8 years. There were 3 450 patients in the SS≤22 group and 449 patients in the SS 23-32 group. Compared with SS≤22 group, the incidence of revascularization was higher in SS 23-32 group (18.9% (85/449) vs. 15.2% (524/3450), log-rank P=0.019). There was no significant difference in all-cause death, cardiac death and recurrent myocardial infarction between the two groups (log-rank P>0.05). Multivariate Cox regression analysis showed that age (HR=1.05, 95%CI 1.02-1.08, P<0.001), chronic obstructive pulmonary disease (HR=3.12, 95%CI 1.37-7.07, P=0.007) and creatinine clearance rate (CCr)<60 ml/min (HR=3.67, 95%CI 2.05-6.58, P<0.001) were independent risk factors for 5-year cardiac death, while left ventricular ejection fraction (HR=0.94, 95%CI 0.91-0.96, P<0.001) was a protective factor. Previous PCI (HR=2.04, 95%CI 1.38-3.00, P<0.001), blood glucose level≥11.1 mmol/L on admission (HR=2.49, 95%CI 1.32-4.70, P=0.005) and CCr<60 ml/min (HR=1.85, 95%CI 1.14-2.99, P=0.012) were independent risk factors for 5-year recurrent myocardial infarction. The SS of 23-32 was independently associated with risk of revascularization (HR=1.54, 95%CI 1.09-2.16, P=0.014), after adjusting for residual SS. Residual SS was not a risk factor for 5-year prognosis. Conclusions: In diabetic patients with low-or intermediate complexity CAD, SS 23-32 is associated with increased risk of 5-year revascularization; the clinical characteristics of the patients are associated with the long-term mortality and recurrent myocardial infarction, but not related to revascularization.

Abstract
OBJECTIVE Lung adenocarcinoma (LUAD) is one of the most common cancers in the world. Protein regulator of cytokinesis 1 (PRC1) plays a role in the tumorigenesis and development of several cancers, including LUAD. The aim of the present study is to assess the characteristics of PRC1 in LUAD in order to find a potential drug that targets PRC1. MATERIALS AND METHODS We investigated the prognostic value of PRC1 in patients with LUAD using Cox analysis of the RNA sequencing data from The Cancer Genome Atlas (TCGA) portal. A link between PRC1 and LUAD progression, cigarette smoking mutation count, aneuploidy, and hypoxia scores was assessed. The relationship between PRC1 and tumor-infiltrating immune cells in LUAD was analyzed and Gene Set Enrichment Analysis (GSEA) was used to study the PRC1-related biological process and signal pathways. Potential drugs targeting PRC1 were identified using DrugBank database and molecular docking. RESULTS PRC1 expression was significantly increased in LUAD. PRC1 could be, therefore, a prognostic biomarker for predicting overall survival in LUAD. PRC1 expression was also related to cancer stage and patient's smoking history. PRC1 positively correlated with mutation count, aneuploidy and hypoxia scores. It was also significantly related to tumor-infiltrating immune cells, especially the activated mast cells. GSEA revealed that PRC1 might be correlated with cell cycle, cytokinesis and p53 signaling pathway. Additionally, fostamatinib was found to be a potential drug targeting PRC1. CONCLUSIONS PRC1 may have a prognostic value for patients with LUAD, and be correlated with the mutation count, aneuploidy, hypoxia and tumor-infiltrating immune cells. Fostamatinib was found to be a potential drug targeting PRC1 in LUAD.

Abstract
PURPOSE The association between aldehyde exposure and bone health in humans remains unclear. This study was to evaluate the association of serum aldehydes with bone mineral density (BMD) and osteopenia/osteoporosis. METHODS We analyzed the US National Health and Nutrition Examination Survey cross-sectional data from 2013 to 2014. Weighted multivariate-adjusted linear regression and logistic regression models were used to assess the association between specific aldehydes and osteopenia/osteoporosis. Associations between aldehyde combinations and BMD were also evaluated using the restricted cubic spline (RCS) method. RESULTS Compared with men in the first tertile, those in the third tertile of propanaldehyde concentration were negatively associated with proximal femur and lumbar spine BMD. Significant inverse associations were observed between benzaldehyde exposure and trochanter BMD in women. Benzaldehyde increased the risk of osteopenia/osteoporosis 2.75-fold [95% confidence interval (CI) = 1.06, 7.11] in the highest tertile in women compared to the lowest tertile concentration. In males, the prevalence of total femur, femur neck, and trochanter osteopenia/osteoporosis was significantly higher in the highest versus the lowest tertile of propanaldehyde exposure, with odds ratios (ORs) of 6.84 (95% CI = 2.33, 20.04), 2.72 (95% CI = 1.18, 6.27), and 3.26 (95% CI = 1.25, 8.56), respectively. RCS regression also showed decreased BMD continuously with increasing serum mixed aldehyde levels. CONCLUSIONS Serum aldehyde concentrations were associated with low BMD and high osteopenia/osteoporosis risk in adults, with propanaldehyde and benzaldehyde being the most critical. Co-exposure to aldehyde combinations was negatively correlated with BMD.

Abstract
Abstract
Aims
Recent research reported that lower low-density lipoprotein cholesterol (LDL-C) is associated with more in-hospital bleeding in acute coronary syndrome (ACS) patients. However, the association between lower LDL-C levels and long-term bleeding in percutaneous coronary intervention (PCI) patients remains unclear.
Methods
A total of 10724 patients treated with PCI enrolled in ourhospital from January 2013 to December 2013. The primary endpoint was the Bleeding Academic Research Consortium (BARC) type 2, 3 or 5 bleeding at 5 years. The secondary endpoint was intracranial hemorrhage. Taking the LDL-C value of 1.8 mmol/L (70 mg/dL) or 1.4 mmol/L (55 mg/dL) as cut-off points, patients were grouped to analyse, respectively.
Results
Among 9697 PCI patients treated with dual antiplatelet therapy finally enrolled, a total of 411 BARC type 2, 3 or 5 bleedings and 42 intracranial hemorrhage were recorded during a follow-up of 5 years. With LDL-C value of 1.8 mmol/L as cut-off point, multivariate Cox regression showed that lower LDL-C level was not associated with the risk for bleeding [hazard ratio (HR): 1.166, 95% confidence interval (CI): 0.879–1.549]. The result was consistent (HR: 1.185; 95% CI: 0.713–1.968) in a 1:4 propensity-score matching cohort (n=1285). For further study, we performed subgroup analysis which showed that lower LDL-C was not associated with the risk for bleeding in ACS (HR: 1.140; 95% CI: 0.846–1.535) or non-ACS patients (HR: 1.284; 95% CI: 0.909–1.813). With LDL-C value of 1.4 mmol/L as cut-off point, Cox regression showed that lower LDL-C level was not associated with the risk for bleeding in total population, ACS or non-ACS patients (P>0.05). The result was consistent in a 1:4 propensity-score matching cohort (n=760) (P>0.05). As for secondary endpoint, lower LDL-C level was not associated with the risk for intracranial hemorrhage whether the LDL-C value is 1.8 or 1.4 mmol/L as the cut-off point (P>0.05).
Conclusions
To the best of our knowledge, we firstly report lower LDL-C level (whether the LDL-C value is 1.8 or 1.4 mmol/L as the cut-off point) was not the independent risk factor of long-term bleeding in PCI population and ACS or non-ACS subgroup populations.

Abstract
Identifying genes associated with wax deposition may contribute to the genetic improvement of ornamental kale. Here, we characterized a candidate gene for wax contents, BoORP3a, encoding an oxysterol-binding protein. We sequenced the BoORP3a gene and coding sequence from the high-wax line S0835 and the low-wax line F0819, which revealed 12 single nucleotide polymorphisms between the two lines, of which six caused five amino acids substitutions. BoORP3a appeared to be relatively well conserved in Brassicaceae, as determined by a phylogenetic analysis, and localized to the endoplasmic reticulum and the nucleus. To confirm the role of BoORP3a in wax deposition, we generated three orp3a mutants in a high-wax kale background via CRISPR/Cas9-mediated genome editing. Importantly, all three mutants exhibited lower wax contents and glossy leaves. Overall, these data suggest that BoORP3a may participate in cuticular wax deposition in ornamental kale.

Abstract
Acute respiratory distress syndrome (ARDS) is a common critical disease, which often leads to poor prognosis in critically ill patients. The excessive respiratory drive in ARDS is related to lung injury. Control of excessive respiratory drive is helpful to reduce lung injury and mortality of ARDS. The mechanisms of abnormal increase in respiratory drive in ARDS include hypoxemia, hypercapnia, stretch reflex caused by alveolar collapse and inflammatory stimulation. Respiratory drive should be evaluated by clinical manifestations, physiological parameters and respiratory mechanics indexes. It is particularly important to make individual therapy strategies according to the evaluation of respiratory drive. Analgesia and sedation combined with muscle relaxation, high positive end-expiratory pressure (PEEP) and prone position can be used to control excess respiratory drive. This article reviews the evaluation and management of excess respiratory drive in ARDS patients.

Abstract
Objectives: To explore the role of computed tomography (CT) severity index (CTSI) and modified CT severity index (MCTSI) in assessing the severity of acute pancreatitis (AP) under the revised Atlanta classification (RAC) and predicting the clinical prognosis. Methods: Based on the prospectively entered AP database, the clinical data of consecutive adult AP inpatients admitted to the Department of Gastroenterology of the First Affiliated Hospital of Nanchang University from January 2012 to December 2020 were retrospectively screened. The imaging data were independently evaluated by two radiologists and entered to the database to calculate the CTSI and MCTSI scores. Their relationship with the difference of RAC severity grade and clinical prognosis was analyzed. Compared with Acute Physiology and Chronic Health Assessment Ⅱ (APACHE Ⅱ) score, the receiver operating characteristic curve was used to evaluate the predictive value of CTSI and MCTSI scores for persistent organ failure and infectious pancreatic necrosis (IPN). Results: A total of 2 612 patients with AP, aged (50±15) years, were included in the study, including 1 547 males (59.2%) and 1 065 females (40.8%). According to RAC standard, AP was divided into 699 cases (26.8%) of mild pancreatitis (MAP), 1 098 cases (42.0%) of moderately severe pancreatitis (MSAP), and 815 cases (31.2%) of severe pancreatitis (SAP). MCTSI judged AP severity similarly to RAC, with 668 cases of MAP (25.6%), 1 207 cases of MSAP (46.2%) and 737 cases of SAP (28.2%), while CTSI judged SAP patients less(400 cases, 15.3%). The severity of AP determined by CTSI and MCTSI scores was significantly correlated with clinical prognosis (r=0.06-0.43, all P<0.05). Compared with APACHE Ⅱ score, CTSI had the highest area under the curve (AUC) for predicting IPN (AUC=0.85, 95%CI: 0.83-0.87), followed by MCTSI (AUC=0.82, 95%CI: 0.80-0.85). APACHE Ⅱ was more accurate in predicting persistent organ failure than CTSI and MCTSI scores,with AUC of 0.73 (95%CI: 0.71-0.75), 0.72 (95%CI: 0.70-0.74) and 0.72 (95%CI: 0.70-0.74), respectively. Conclusions: AP severity judged by MCTSI is consistent with RAC, and SAP patients judged by CTSI are less than RAC. CTSI and MCTSI are significantly correlated with clinical prognosis. CTSI and MCTSI have higher accuracy in predicting IPN, but lower accuracy in predicting persistent organ failure than APACHE Ⅱ.

Abstract
We report high-precision measurements of the deeply virtual Compton scattering (DVCS) cross section at high values of the Bjorken variable x_{B}. DVCS is sensitive to the generalized parton distributions of the nucleon, which provide a three-dimensional description of its internal constituents. Using the exact analytic expression of the DVCS cross section for all possible polarization states of the initial and final electron and nucleon, and final state photon, we present the first experimental extraction of all four helicity-conserving Compton form factors (CFFs) of the nucleon as a function of x_{B}, while systematically including helicity flip amplitudes. In particular, the high accuracy of the present data demonstrates sensitivity to some very poorly known CFFs.

Abstract
OBJECTIVE To investigate the roles of angiotensin-converting enzyme 2 (ACE2) in ozone-induced pulmonary inflammation and airway remodeling in mice. METHODS Sixteen wild-type (WT) C57BL/6J mice and 16 ACE2 knock-out (KO) mice were exposed to either filtered air or ozone (0.8 ppm) for 3 h per day for 5 consecutive days. Masson's staining and HE staining were used to observe lung pathologies. Bronchoalveolar lavage fluid (BALF) was collected and the total cell count was determined. The total proteins and cytokines in BALF were determined by BCA and ELISA method. The transcription levels of airway remodeling-related indicators in the lung tissues were detected using real-time quantitative PCR. The airway resistance of the mice was measured using a small animal ventilator with methacholine stimulation. RESULTS Following ozoneexposure ACE2 KO mice had significantly higher lung pathological scores than WT mice (P < 0.05). Masson staining results showed that compared with ozone-exposed WT mice, ozone-exposed ACE2 KO mice presented with significantly larger area of collagen deposition in the bronchi [(19.62±3.16)% vs (6.49±1.34)%, P < 0.05] and alveoli [(21.63±3.78)% vs (4.44±0.99)%, P < 0.05]. The total cell count and total protein contents in the BALF were both higher in ozone-exposed ACE2 KO mice than in WT mice, but these differences were not statistically significant (P > 0.05). The concentrations of IL-6, IL-1β, TNF-α, CXCL1/KC and MCP-1 in the BALF were all higher in ozone-exposed ACE2 KO mice than in ozone-exposed WT mice, but only the difference in IL-1β was statistically significant (P < 0.05). The transcription levels of MMP-9, MMP-13, TIMP 4, COL1A1, and TGF-β in the lung tissues were all significantly higher in ozone-exposed ACE2 KO mice (P < 0.01). No significant difference was found in airway resistance between ozone-exposed ACE KO mice and WT mice after challenge with 0, 10, 25, or 100 mg/mL of methacholine. CONCLUSION ACE2 participates in ozone-induced lung inflammation and airway remodeling in mice.

Abstract
The morphological diversity of leaf margin shapes is an identifying characteristic of many plant species. In our previous work, BoALG10 (α-1,2 glycosyltransferase) was predicted to be a key regulator of leaf margin shape in ornamental kale (Brassica oleracea var. acephala). An alanine and a leucine residue in the conserved domain of the smooth-margined S0835 were replaced by an aspartate and a phenylalanine, respectively, in the corresponding positions of the feathered-margined F0819. However, the expression pattern and function of this gene remain unclear. Here, we examined the expression patterns of BoALG10 using quantitative real-time PCR, and found that statistically significant differences in expression existed between F0819 and S0835 in nine developmental stages. The BoALG10 protein localized to the endoplasmic reticulum. The function of BoALG10 was then examined using complementary mutant assays. The overexpression strains phenocopied the smooth leaf margin after introduction of BoALG10 S0835 into the feathered-margined inbred line F0819. Simultaneously, irregular dissections appeared in the leaf margins of knockout mutants KO-1 and KO-2, which were generated by CRISPR/Cas9 technology from the smooth-margined inbred line S0835. Microscopic observation showed that the leaf margin cells of the smooth-margined plants S0835 and OE-3 were arranged regularly, while the cells of the feathered-margined plants F0819 and KO-1 were of inconsistent size and distributed in an irregular manner, particularly around the indentations of the leaf. This elucidation of BoALG10 function provides a novel insight into the morphological regulation of leaf margin shape.

Abstract
Enormous evidences in clinic and experimental studies have demonstrated that salvianolate (Sal) could treat cardiovascular diseases such as myocardial infarction (MI), but the underlying mechanism was still needed to be explored. This study aims to investigate the effect of Sal on cardiomyocyte remodeling after MI in rats and explore whether the possible mechanism was related to decreasing the β-myosin heavy chain (β-MHC) expression in cardiomyocytes via the calcineurin (CaN)/nuclear factor C3 of the activated T cell (NFATc3) pathway. Both MI model and angiotensin II induced primary myocardial cells obtained from rats were used in this study. After treatment with Sal, the cardiac function was assessed by color Doppler echocardiography, while MI area, myocardial cell area and heart mass index (HMI) were analyzed via Masson and hematoxylin and eosin staining (HE) stain, respectively. Additionally, CaN activity, and CaN, NFATc3, β-MHC mRNA and protein expressions in myocardial tissue and myocardial cells were tested via corresponding methods, mainly including real-time fluorescence-based quantitative polymerase chain reaction (RT-qPCR), Western blot (WB), immunohistochemistry and fluorescence staining analysis. As a result we obtained the high dose of Sal in vivo could perform beneficial effects on cardiomyocyte remodeling of MI rats, mainly manifesting as improving fractional shortening and ejection fraction rates, reducing the MI area, myocardial cross-sectional area and HMI (P<0.05, 0.01), inhibiting the activity of CaN in myocardial tissue, down-regulating b-MHC mRNA and protein expressions, and decreasing the nuclear translocation of NFATc3 (P<0.05). In the in vitro experiments, 10 μmol/L of Sal could inhibit the increase of the myocardial cell area and CaN activity, down-regulate the mRNA and protein of CaN A subunit, β-MHC; and inhibit the nuclear translocation of NFATc3 (P<0.05, 0.01). In conclusion: use of Sal can improve cardiomyocyte remodeling and down-regulate the expression of β-MHC in cardiomyocytes, of which the mechanism might be related to the reduction of the nuclear translocation of NFATc3 as well as the down-regulation of CaNA subunit expression and/or the inhibition of CaN activity. The results will provide a laboratory basis for the clinical application of Sal.

Abstract
A CRISPR/Cas9-based knockout assay verified that BoDFR1 drives anthocyanin accumulation in ornamental kale and that BoDFR2, an ortholog of BoDFR1, is redundant. Anthocyanins are widely distributed in nature and give plants their brilliant colors. Leaf color is an important trait for ornamental kale. In this study, we measured anthocyanin contents and performed transcriptome deep sequencing (RNA-seq) of leaves from pink and green ornamental kale. We observed substantial differences in the expression levels of the two DIHYDROFLAVONOL 4-REDUCTASE-encoding genes BoDFR1 (Bo9g058630) and its ortholog BoDFR2 (Bo2g116380) between green-leaved and pink-leaved kale by RNA-seq and RT-qPCR. We cloned and sequenced BoDFR1 and BoDFR2 from both types of kale. We identified a 1-bp insertion in BoDFR1 and a 2-bp insertion in BoDFR2 in green-leaved kale compared to the sequences obtained from pink-leaved kale, both mapping to the second exon of their corresponding gene and leading to premature termination of translation. To confirm the genetic basis of the absence of anthocyanins in green kale, we used CRISPR/Cas9 genome editing to separately knock out BoDFR1 or BoDFR2 in the pink-leaved ornamental kale inbred line P23. We detected very low accumulation of anthocyanins in the resulting mutants Bodfr1-1 and Bodfr1-2, while Bodfr2-1 and Bodfr2-2 had anthocyanin levels comparable to those of the wild-type. We conclude that the insertion in BoDFR1, rather than that in BoDFR2, underlies the lack of anthocyanins in green-leaved ornamental kale. This work provides insight into the function of DFR and will contribute to germplasm improvement of ornamental plants.

Abstract
Objective: To explore and compare the effect of standard or prolonged dual antiplatelet therapy (DAPT) on the long-term prognosis of elderly patients with coronary heart disease complicated with diabetes mellitus after drug-eluting stent (DES) implantation. Methods: Consecutive patients with diabetes mellitus, ≥65 years old, underwent DES implantation, and had no adverse events within 1 year after operation underwent percutaneous coronary intervention (PCI) from January to December 2013 in Fuwai Hospital were enrolled in this prospective cohort study. These patients were divided into three groups according to DAPT duration: standard DAPT duration group (11 ≤ DAPT duration≤ 13 months) and prolonged DAPT duration group (13<DAPT duration≤ 24 months; DAPT duration>24 months). All the patients were followed up at 1, 6 months, 1, 2 and 5 years in order to collect the incidence of major adverse cardiovascular and cerebrovascular events (MACCE), and type 2 to 5 bleeding events defined by the Federation of Bleeding Academic Research (BARC). MACCE were consisted of all cause death, myocardial infarction, target vessel revascularization or stroke. The incidence of clinical adverse events were compared among 3 different DAPT duration groups, and Cox regression model were used to analyze the effect of different DAPT duration on 5-year long-term prognosis. Results: A total of 1 562 patients were enrolled, aged (70.8±4.5) years, with 398 female (25.5%). There were 467 cases in standard DAPT duration group, 684 cases in 13<DAPT duration≤ 24 months group and 411 cases in DAPT duration>24 months group. The patients in standard DAPT duration group and the prolonged DAPT duration groups accounted for 29.9% (467/1 562) and 70.1% (1 095/1 562), respectively. The 5-year follow-up results showed that the incidence of all-cause death in 13<DAPT duration≤ 24 months group (4.8%(33/684) vs. 8.6%(40/467),P=0.011) and DAPT duration>24 month group(4.1%(17/411) vs. 8.6%(40/467),P=0.008) were significantly lower than in standard DAPT group. The incidence of myocardial infarction in 13<DAPT duration≤ 24 months group was lower than in standard DAPT duration group (1.9%(13/684) vs. 5.1%(24/467),P=0.002). The incidence of MACCE in 13<DAPT duration≤ 24 months group was the lowest (standard DAPT duration group, 13<DAPT duration≤ 24 months group and DAPT duration>24 month group were 19.3% (90/467), 12.3% (84/684), 20.2% (83/411), respectively, P<0.001). There was no significant difference in the incidence of stroke and bleeding events among the three groups (all P>0.05). Multivariate Cox analysis showed that compared with the standard DAPT group, prolonged DAPT to 13-24 months was negatively correlated with MACCE (HR=0.601, 95%CI 0.446-0.811, P=0.001), all-cause death (HR=0.568, 95%CI 0.357-0.903, P=0.017) and myocardial infarction (HR=0.353, 95%CI 0.179-0.695, P=0.003). DAPT>24 months was negatively correlated with all-cause death (HR=0.687, 95%CI 0.516-0.913, P=0.010) and positively correlated with revascularization (HR=1.404, 95%CI 1.116-1.765, P=0.004). There was no correlation between prolonged DAPT and bleeding events. Conclusions: For elderly patients with coronary heart disease complicated with diabetes mellitus underwent DES implantation, and had no MACCE and bleeding events within 1 year after operation, appropriately prolonging of the DAPT duration is related to the reduction of the risk of cardiovascular adverse events. Patients may benefit the most from the DAPT between 13 to 24 months. In addition, prolonging DAPT duration does not increase the incidence of bleeding events in this patient cohort.

Abstract
Leaf color is a crucial agronomic trait in ornamental kale. However, the molecular mechanism regulating leaf pigmentation patterns in green and white ornamental kale is not completely understood. To address this, we performed transcriptome and pigment content analyses of green and white kale leaf tissues. A total of 5,404 and 3,605 different expressed genes (DEGs) were identified in the green vs. white leaf and the green margin vs. white center samples. Kyoto Encyclopedia of Genes and Genome (KEGG) pathway enrichment analysis showed that 24 and 15 common DEGs in two pairwise comparisons were involved in chlorophyll metabolism and carotenoid biosynthesis, respectively. Seventeen genes related to chlorophyll biosynthesis were significantly upregulated in green leaf tissue, especially chlH and por. Of the 15 carotenoid biosynthesis genes, all except CYP707A and BG1 were lower expressed in white leaf tissue. Green leaf tissue exhibited higher levels of chlorophyll and carotenoids than white leaf tissue. In addition, the DEGs involved in photosystem and chlorophyll-binding proteins had higher expression in green leaf tissue. The PSBQ, LHCB1.3, LHCB2.4, and HSP70 may be key genes of photosynthesis and chloroplast formation. These results demonstrated that green and white coloration in ornamental kale leaves was caused by the combined effects of chlorophyll and carotenoid biosynthesis, chloroplast development, as well as photosynthesis. These findings enhance our understanding of the molecular mechanisms underlying leaf color development in ornamental kale.

Abstract
Chrysanthemum white rust (CWR), a disease caused by the fungus Puccinia horiana Henn., seriously impairs the production and ornamental value of chrysanthemums. We previously isolated the disease-resistance gene CmWRKY15-1 from the chrysanthemum and generated CmWRKY15-1 transgenic plants. Here, we determined that CmWRKY15-1-overexpressing lines of the susceptible cultivar 'Jinba' show higher defensive enzyme activity and lower H2O2 levels than a wild type after inoculation with P. horiana, indicating that CmWRKY15-1 positively regulates plant responses to P. horiana. To further explore the mechanism underlying this effect, we performed RNA sequencing using the leaves of wild-type and CmWRKY15-1-RNA interference lines of the resistant cultivar 'C029' after treatment with P. horiana. We identified seven differentially expressed genes in the salicylic acid (SA) pathway, including CmNPR1 (Non-expressor of pathogenesis-related genes 1), encoding an important regulator of this pathway. We isolated the CmNPR1 promoter by hiTAIL-PCR and predicted that it contains pathogen-induced W-box elements. The promoter region of CmNPR1 was activated by P. horiana in a β-glucuronidase activity assay. Yeast one-hybrid assays showed that CmWRKY15-1 binds to the CmNPR1 promoter region to regulate its expression. Finally, we confirmed the interaction between CmWRKY15-1 and CmNPR1 in a bimolecular fluorescence complementation assay. We propose that CmWRKY15-1 interacts with CmNPR1 to activate the expression of downstream pathogenesis-related genes that enhance resistance to P. horiana through the SA pathway. These findings shed light on the mechanism underlying resistance to CWR.

Abstract
We present new precision measurements of the elastic electron-proton scattering cross section for momentum transfer (Q^{2}) up to 15.75 (GeV/c)^{2}. Combined with existing data, these provide an improved extraction of the proton magnetic form factor at high Q^{2} and double the range over which a longitudinal or transverse separation of the cross section can be performed. The difference between our results and polarization data agrees with that observed at lower Q^{2} and attributed to hard two-photon exchange (TPE) effects, extending to 8 (GeV/c)^{2} the range of Q^{2} for which a discrepancy is established at >95% confidence. We use the discrepancy to quantify the size of TPE contributions needed to explain the cross section at high Q^{2}.

Abstract
We report measurements of the exclusive neutral pion electroproduction cross section off protons at large values of x_{B} (0.36, 0.48, and 0.60) and Q^{2} (3.1 to 8.4 GeV^{2}) obtained from Jefferson Lab Hall A experiment E12-06-014. The corresponding structure functions dσ_{T}/dt+εdσ_{L}/dt, dσ_{TT}/dt, dσ_{LT}/dt, and dσ_{LT^{'}}/dt are extracted as a function of the proton momentum transfer t-t_{min}. The results suggest the amplitude for transversely polarized virtual photons continues to dominate the cross section throughout this kinematic range. The data are well described by calculations based on transversity generalized parton distributions coupled to a helicity flip distribution amplitude of the pion, thus providing a unique way to probe the structure of the nucleon.

Abstract
Fish intestine contains different types of microbiomes, and bacteria are the dominant microbiota in fishes. Studies have identified various core gut bacteria in fishes. However, little is known about the composition and their relative functions of gut microbial community along the intestine. To explore this, the current study investigated the microbial community distribution along the gut in Anguilla japonica. By 16S rRNA gene sequencing, we profiled the gut microbiota in eel along the three regions (anterior intestine (AI), the middle intestine (MI) and the posterior intestine (PI)). Results suggested that the three regions did not have significant differences on the observed species and diversities. The cluster tree analysis showed that the bacteria community in MI was closer to PI than the AI. The dominant bacteria in AI were the Proteobacteria, in which the majority was graduated replaced by Bacteroidetes along the gut to PI region. Through PICRUSt analysis, shifts in the bacterial community along the gut were found to affect the genetic information processing pathways. Higher levels of translation and transcriptional pathway activities were found in MI and PI than in AI. The dominant bacterial species were different among the regions and contributed to various biological functions along the gut.

Abstract
OBJECTIVE Dysregulated lipid metabolism has been reported in the progression of hepatocellular carcinoma (HCC). In the present study, we investigated the molecular characteristics of lipid-metabolism-related genes (IMRGs) as prognostic markers for HCC. MATERIALS AND METHODS Multi-dimensional bioinformatics analyses were performed to comprehensively analyze IMRGs, and to construct prognostic prediction signatures. RESULTS Data of 770 HCC patients and their corresponding 776 IMRGs were downloaded from three databases. Patients were classified into 2 molecular clusters that were associated with overall survival, clinical characteristics, and immune cells. The biological functions of the IMRGs differentially expressed between the 2 clusters were associated with tumor-related metabolic pathways. A 6 IMRG signature (6-IS), consisting of FMO3, SLC11A1, RNF10, KCNH2, ME1, and ZIC2, was established as an independent prognostic factor for HCC. The performance of the signature of 6-IS prognostic was verified in a validation set and compared to an external data set. It was revealed that the 6-IS could effectively predict the prognosis of patients with HCC. CONCLUSIONS This study provides new insights into the role of IMRGs in the pathogenesis of HCC, and presents a novel signature (6-IS) to predict the prognosis of HCC.

Abstract
BACKGROUND Anthocyanin, chlorophyll, and carotenoid pigments are widely distributed in plants, producing various colors. Ornamental kale (Brassica oleracea var. acephala DC) which has colorful inner leaves is an ideal plant to explore how these three pigments contribute to leaf color. The molecular mechanisms of the coloration in ornamental kale could provide reference for exploring the mechanisms of pigmentation in other plants. RESULTS In this study, we sequenced the transcriptome and determined the pigment contents of an unusual cultivar of ornamental kale with three different types of leaf coloration: pink (C3), light pink (C2), and variegated pink-green (C1). A total of 23,965 differentially expressed genes were detected in pairwise comparisons among the three types of leaves. The results indicate that Bo9g058630 coding dihydroflavonol 4-reductase (DFR) and Bo3g019080 coding shikimate O-hydroxycinnamoyltransferase (HCT) acted in anthocyanin biosynthesis in pink leaves. Bo1g053420 coding pheophorbidase (PPD) and Bo3g012430 coding 15-cis-phytoene synthase (crtB) were identified as candidate genes for chlorophyll metabolism and carotenoid biosynthesis, respectively. The transcription factors TT8, MYBL2, GATA21, GLK2, and RR1 might participate in triggering the leaf color change in ornamental kale. Anthocyanin content was highest in C3 and lowest in C1. Chlorophyll and carotenoid contents were lowest in C2 and highest in C1. CONCLUSIONS Based on these findings, we suspected that the decrease in anthocyanin biosynthesis and the increase in chlorophyll and carotenoid biosynthesis might be the reason for the leaf changing from pink to variegate pink-green in this unusual cultivar. Our research provides insight into the molecular mechanisms of leaf coloration in ornamental kale, contributing to a theoretical foundation for breeding new varieties.

Abstract
Objective: To explore the prognosis effect of the expression of long-chain non-coding RNA (lncRNA) MBNL1-AS1 on acute myeloid leukemia (AML) patients. Methods: One hundred and twenty-five AML patients of the Cancer Genome Atlas (TCGA) from November 2001 to March 2010 were involved, including 70 patients who received chemotherapy only and other 55 patients treated with allogeneic hematopoietic stem cell transplantation (allo-HSCT) in addition to chemotherapy. According to the median expression of lncRNA MBNL1-AS1, patients of chemotherapy group were divided into high expression sub-group(n=35) and low expression sub-group (n=35), and patients of allo-HSCT group were also divided into high expression sub-group (n=28) and low expression sub-group (n=27) for prognosis analysis. Clinical characteristics at diagnosis, including peripheral white blood cell counts (WBC), blast percentages in peripheral blood and bone marrow (BM), French-American-British (FAB) subtypes and the frequencies of common genetic mutations in AML were described. The event-free survival (EFS) rate and overall survival (OS) rate of patients in different groups were analyzed, and the influence of the clinical characteristics of patients on the prognosis of AML was analyzed by COX multivariate analysis. Results: In the chemotherapy group, patients with low lncRNA-MBNL1-AS1 expression had significantly lower EFS and OS (60.0%, 8.6%) than patients with high lncRNA-MBNL1-AS1 expression (68.6%, 34.3%) (χ²=7.817, 10.880, all P<0.01). However, in the alloHSCT group, no significant differences were observed in EFS and OS of patients between high and low expression groups of lncRNA-MBNL1-AS1 (all P>0.05). COX multivariate analysis confirmed that age≥60 years old (EFS: HR (95%CI): 6.934 (1.918-25.075),P=0.003;OS: HR (95%CI): 4.119 (1.812-9.364), P=0.001), and low expression of lncRNA MBNL1-AS1 (EFS: HR (95%CI): 0.354 (0.126-0.941), P=0.038; OS: HR (95%CI): 0.424 (0.231-0.778), P=0.006)were independent risk factors for EFS and OS in the chemotherapy group. Conclusion: The long-chain non-coding RNA MBNL1-AS1 is related to the prognosis of AML, and its low expression is an independent poor prognostic factor in AML patients.

Abstract
Objective: To investigate the influence and critical period of pregnancy-related anxiety during pregnancy on the neurobehavioral development of infants. Methods: The subjects of this study were derived from the Ma'anshan Birth Corhot. From May 2013 to September 2014, a total of 3 474 pregnant women who registered in Ma 'anshan Maternal and Child Health Care Center were enrolled in the study. A total of 2 242 mother-infant pairs who completed three times assessments of maternal anxiety and at least once assessment of infants' neurobehavioral development were included in the final analysis. Maternal pregnancy-related anxiety was assessed by the Pregnancy-Related Anxiety Questionnaire during the first, second and third trimesters of pregnancy. When their children were at 6 and 18 months, their neurobehavioral development was evaluated using the Ages & Stages Questionnaire-China. The influence of maternal pregnancy-related anxiety on the neurobehavioral development of infants was analyzed by bi-nominal logistic regression. Results: The age of 2 242 pregnant women was (26.62±3.65) years, and the proportion of boys, low birth weight and exclusive breastfeeding for 6 months was 50% (1 120/2 242), 1.7% (38/2 242) and 11.5% (252/2 191), respectively. The detection rates of pregnancy-related anxiety during the first, second and third trimester were 24.9% (558), 28.6% (642) and 30.3% (674), respectively. After controlling confounding variables and other two trimester's anxiety, only pregnancy-related anxiety during the third trimester (not first or second trimester) significantly increased the risk of developmental delay in the domain of communication (relative risk, RR = 3.52, 95% confidence interval, CI: 1.89-6.58) and personal-social (RR=2.46, 95%CI: 1.10-5.49) at the 6 months of age, as well as in the domain of fine motor (RR=2.07, 95%CI: 1.11-3.85), problem-solving domains (RR=2.31, 95%CI: 1.24-4.31). Conclusion: Maternal pregnancy-related anxiety was associated with the risk of neurobehavioral development of infants, and the third trimester may be the critical period.

Abstract
PURPOSE Gene polymorphisms of pro-inflammatory cytokines such as tumor necrosis factor-α (TNF-α), interleukin-1 (IL-1) and interleukin-6 (IL-6) may influence the risk of Graves' disease, but the results of so far published studies remain inconclusive. Therefore, the authors conducted this meta-analysis to assess relationships between TNF-α/IL-1/IL-6 polymorphisms and the risk of Graves' disease by pooling the findings of all relevant studies. METHODS A comprehensive literature searching of Pubmed, Embase, Web of Science and CNKI was conducted by the authors, and twenty-eight studies were found to be eligible for pooled analyses. RESULTS The pooled meta-analyses results showed that genotypic frequencies of TNF-α rs1800629, IL-1A rs1800587, IL-6 rs1800795 and IL-6 rs1800796 polymorphisms among patients with Graves' disease and control subjects differed significantly. Moreover, we found that genotypic frequencies of TNF-α rs1800629 and IL-6 rs1800795 polymorphisms among patients with Graves' disease and control subjects in Caucasians differed significantly, and genotypic frequencies of IL-1A rs1800587, IL-1B rs16944, IL-6 rs1800795 and IL-6 rs1800796 polymorphisms among patients with Graves' disease and control subjects in Asians also differed significantly. Nevertheless, we did not detect such genotypic frequencies differences for TNF-α rs361525 and IL-1B rs1143627 polymorphisms. CONCLUSIONS This meta-analysis suggests that TNF-α rs1800629, IL-1A rs1800587, IL-6 rs1800795 and IL-6 rs1800796 polymorphisms may influence the risk of Graves' disease in overall population. Moreover, TNF-α rs1800629 and IL-6 rs1800795 polymorphisms may influence the risk of Graves' disease in Caucasians, while IL-1A rs1800587, IL-1B rs16944, IL-6 rs1800795 and IL-6 rs1800796 polymorphisms may influence the risk of Graves' disease in Asians.

Abstract
Objective: To evalutate the safety and efficacy of infrahepatic inferior vena cava clamping robot-assisted laparoscopic liver resection. Methods: All data about 24 patients with robotic liver resection at Hepatic Surgery Center,Tongji Hospital,Tongji Medical College,Huazhong University of Science and Technology between February 2015 and December 2017 were collected and analyzed. These patients were divided into two groups based on different methods to decrease central venous pressure. Eight patients(6 males and 2 females,aged 49 years(range:50 to 56 years)) were applied with infrahepatic inferior vena cava clamping,and the other 16 matched cases (15 males and 1 female,aged 53 years(range:38 to 69 years)) were categorized into lowering central venous pressure group. Intraoperative blood loss,blood transfusion,intraoperative hemodynamic parameters,postoperative complications,and renal function were compared by t-test,non-parametric test,χ2 test,or Fisher exact test. Results: There was significantly difference in the intraoperative blood loss between the infrahepatic vena cava clamping group and the lowering central venous group(200(220) ml (range:100 to 400 ml) vs. 750(800) ml (range:100 to 2 000 ml),Z=‒2.169,P=0.030). The clamping time of portal triad and infrahepatic inferior vena cava were 24 (18) minutes and 29 (20) minutes in the infrahepatic inferior vena cava clamping group, and portal triad clamping time was 23 (23) minutes in the low central venous group. There was no significant difference between the two groups (Z=‒0.323, P=0.747). There was no intraoperative blood transfusion in the infrahepatic inferior vena cava clamping group, and 5 cases in the low central venous group, with a transfusion volume of 1.5(1.5)U. The difference between the two groups was statistically significant (Z=‒3.353, P=0.001). However, the mean arterial pressure in the infrahepatic vena cava clamping group decreased from (88.6±4.9) mmHg to (67.4±3.8) mmHg(1 mmHg=0.133 kPa), which was lower than that of lowering central venous group (72.4±3.3) mmHg (t=2.315,P=0.003). And there were no significant differences related to postoperative complications rate or hepatic and renal function in both groups. Conclusion: The infrahepatic inferior vena cava technology is safe and feasible to decrease central venous pressure during robotic liver resections,which will not affect the recovery of hepatic and renal functions.

Abstract
Diabetic or hyperglycaemic conditions stimulate the inflammatory response, excessive accumulation of extracellular matrix, and result in glomerulosclerosis, a scarring process of diabetic nephropathy. c-Jun activation domain-binding protein 1 (JAB1) functions as a regulator of pathways involved in cellular apoptosis and proliferation. The role of JAB1 in diabetic nephropathy was investigated in this study. Firstly, glomerular mesangial cells (GMCs) were treated with high glucose, and high glucose conditions induced up-regulation of JAB1 in the GMCs. Moreover, IL-6, TNF-α, MCP-1, and IL-1β were also elevated in high glucose-induced GMCs. Secondly, silencing of JAB1 reduced the levels of IL-6, TNF-α, MCP-1, and IL-1β in high glucose-induced GMCs. In addition, silencing of JAB1 attenuated the high glucose-induced decrease of superoxide dismutase (SOD) and the increase of reactive oxygen species (ROS) and malondialdehyde (MDA). The increased TGF-β1, collagen I, collagen IV, and fibronectin levels in high glucose-induced GMCs were restored by knockdown of JAB1. Thirdly, angiopoietin-like protein 2 (ANGPTL2) expression was reduced by JAB1. Over-expression of ANGPTL2 weakened the JAB1 silence-induced decrease of IL-6, TNF-α, MCP-1, IL-1β, TGF-β1, collagen I, collagen IV, and fibronectin. In conclusion, silencing of JAB1 reduced extracellular matrix deposition and suppressed inflammation in high glucose-induced GMCs through down-regulation of ANGPTL2.

Abstract
Overexpression and virus-induced gene silencing verified BoDFR1 conferred the anthocyanin accumulation in pink-leaved ornamental kale. Leaf color is an essential trait in the important horticultural biennial plant ornamental kale (Brassica oleracea var. acephala). The identity of the gene conferring this striking trait and its mode of inheritance are topics of debate. Based on an analysis of F1, F2, BC1P1, and BC1P2 ornamental kale populations derived from a cross between a pink-leaved P28 and white-leaved D10 line, we determined that the pink leaf trait is controlled by a semi-dominant gene. We cloned two genes potentially involved in anthocyanin biosynthesis in ornamental kale: Bo9g058630 and Bo6g100940. Based on their variation in sequence, we speculated that Bo9g058630, encoding the kale dihydroflavonol-4 reductase (BoDFR1) enzyme, plays a critical role in the development of the pink leaf trait. Indeed, an InDel marker specific for BoDFR1 completely co-segregated with the pink leaf trait in our F2 population. We then generated the 35Spro: DFR-GUS overexpression vector, which we transformed into D10. Overexpression of BoDFR1 indeed restored some anthocyanin accumulation in this white-leaved parental line. In addition, we targeted BoDFR1 in P28 using virus-induced gene silencing. Again, silencing of BoDFR1 resulted in a substantial decrease in anthocyanin accumulation. This work lays the foundation for further exploration of the mechanism underlying anthocyanin accumulation in pink-leaved ornamental kale.

Abstract
Chrysanthemum white rust disease, which is caused by the fungus Puccinia horiana Henn., severely reduces the ornamental quality and yield chrysanthemum. WRKY transcription factors function in the disease-resistance response in a variety of plants; however, it is unclear whether members of this family improve resistance to white rust disease in chrysanthemum. In this study, using PCR, we isolated a WRKY15 homologous gene, CmWRKY15-1, from the resistant chrysanthemum cultivar C029. Real-time quantitative PCR (RT-qPCR) revealed that CmWRKY15-1 exhibited differential expression patterns between the immune cultivar C029 and the susceptible cultivar Jinba upon P. horiana infection. In addition, salicylic acid (SA) treatment strongly induced CmWRKY15-1 expression. Overexpression of CmWRKY15-1 in the chrysanthemum-susceptible cultivar Jinba increased tolerance to P. horiana infection. Conversely, silencing CmWRKY15-1 via RNA interference (RNAi) in C029 increased sensitivity to P. horiana infection. We also determined that P. horiana infection increased both the endogenous SA content and the expression of salicylic acid biosynthesis genes in CmWRKY15-1-overexpressing plants, whereas CmWRKY15-1 RNAi plants exhibited the opposite effects under the same conditions. Finally, the transcript levels of pathogenesis-related (PR) genes involved in the SA pathway were positively associated with CmWRKY15-1 expression levels. Our results demonstrated that CmWRKY15-1 plays an important role in the resistance of chrysanthemum to P. horiana by influencing SA signaling.

Abstract
Abstract
Background
Contrast-induced nephropathy (CIN) is a frequent complication after percutaneous coronary intervention (PCI), and is associated with poor outcome. However, the optimal definition of CIN has been debated because of its different incidence and influence on prognosis. At present, there are limited data regarding th impact of different CIN definitions on long-term mortality in patients undergoing elective PCI.
Purpose
To explore the influence of two classical CIN definitions on long-term mortality and identify which definition was more suitable for predicting long-term mortality in patients undergoing elective PCI..
Methods
We prospectively observed 5600 consenting patients undergoing PCI from January 2012 to December 2018. Two classical CIN definitions include those defined by ESUR[Contrast-media-induced nephrotoxicity (CMN)] and AKIN[contrast induced acute kidney injury (CI-AKI)]. CMN was defined as an increase in serum creatinine (SCr) ≥25% or 0.5 mg/dLabove thebaseline level within 3 days,while CI-AKI wasdefined as an increase in SCr ≥50% or 0.3 mg/dL within 48hs after contrast medium exposure.The association of CIN with long-term mortality was investigated by Cox regression analysis.Interaction analyses were performed for long-term mortality across subgroups.
Results
The incidence of CIN according to ESUR (CMN) and AKIN (CI-AKI) definition were18.3% (n=1023) and 6.1% (n=342), respectively. During a median follow-up of 2 years, after adjusting other potential risk factors, multivariable cox regression analysis revealed CIN was a risk factor for long-term mortality [hazard ratio (HR): 2.021, 95% confidence interval (CI): 1.389–2.938, P<0.0001] according to AKIN definition, but not for ESUR definition (HR: 1.344, 95% CI: 0.982–1.838, P>0.05). Further interaction analysis showed that there was a significant interaction between age >75ys and CMN for long-term mortality (P=0.042) while no such association was observed between age >75ys and CI-AKI (P=0.806).
Conclusions
CIN defined by AKIN may be more suitable for predicting long-term mortality in patients undergoing elective PCI. However, in elderly patients, CIN defined by ESUR could also be used for predicting long-term mortality.

Abstract
Objective: To estimate the effect of comorbid gestational diabetes mellitus (GDM) and depression on glucose metabolism and neonatal morphology. Methods: From March 2015 to October 2018, recruited 18 to 28 weeks pregnant women who met the criteria in the Hefei First People's Hospital or First Affiliated Hospital of Anhui Medical University or Anhui Maternal and Child Health Hospital, including a total of 4 380 study subjects, of which the birth outcome information of 3 827 newborns were collected. The self-made questionnaire "Maternal Health Questionnaire for Hefei City" and Edinburgh Postpartum Depression Scale were used to obtain basic demographic characteristics and emotional state of depression. Data from the 75-g oral-glucose-tolerance test were obtained at 24-28 weeks of gestation. After delivery, delivery outcome information were collected from the hospital medical records. Covariance analysis was used to analyze the differences in glucose metabolism indicators and neonatal outcome indicators in pregnant women with different GDM and depression status. Multiple logistic regression model was used to analyze the correlation between GDM and depression, with different groups of GDM and depression status (no GDM and depression, simple depression, simple GDM, comorbid GDM and depression)as independent variables and whether they were large for gestational age as dependent variables. The interaction between GDM and depression was also analyzed. Results: The 4 380 pregnant women were (28.8±4.2) years old. The incidence of GDM was 19.5% (852/4 380), and the detection rates of depression in the second and third trimesters were 12.1% (526/4 380) and 12.3% (536/4 367). PG-1h and AUC in the comorbid GDM and depression group were significantly higher than those in the group with no GDM and depression (P<0.05) and the single GDM group (P<0.05). After adjusting for factors such as the childbirth age, education level, family's main economic income, BMI before pregnancy, parity, number of physical activities, and weight gain during pregnancy, compared with the group with no GDM and depression, the RR(95%CI) of LGA occurred in the single depression group, the single GDM group and the comorbid group were 1.31(0.89-1.91), 1.51(1.14-2.00) and 2.43(1.29-4.57), respectively. Further analysis showed that the association between GDM pregnant women with depression and newborn LGA [RR (95%CI): 2.12 (1.01-4.49)] was stronger than that between GDM pregnant women without depression and newborn LGA [RR (95%CI): 1.50 (1.12-1.99)], the P interaction value was<0.05. Conclusion: The status of comorbid GDM and depression can impair glucose metabolism and increase the risk of LGA.

Abstract
The aim of this study was to investigate the differential expression of micro ribonucleic acid (miR)- 125b in acute myocardial infarction (AMI) cases, and to explore the mechanism by which it affects cardiac function. Sprague-Dawley rats were used for AMI modeling, and the expression of miR-125b in the myocardial tissues of AMI rats was detected via fluorescence quantitative reverse transcription-polymerase chain reaction (qRT-PCR). Thereafter, the target genes of miR-125b were collected and uploaded to WenGestalt for gene ontology (GO) and pathway enrichment analyses. In-vitro experiments were then applied to determine the p38-sirtuin 1 (Sirt1)-p53 expression change and cardiomyocyte apoptosis under down-regulation of miR-125b. Next, the interaction between miR-125b and its target genes was verified by luciferase reporter gene assay. The expression of miR-125b in the cardiac tissues was decreased in theAMI group compared with that in the Sham group (p<0.05). The luciferase reporter gene assay confirmed that p38 was the target gene of miR-125b. Furthermore, the down-regulated expression of miR-125b in H9C2 cells up-regulated the protein expressions of p38 and phosphorylated p38, thus activating the Sirt1-p53 signaling pathway. Moreover, the down-regulation of miR-125b expression in H9C2 cells gave rise to the elevated apoptosis rate, and the down-regulated expression of miR-125b induced cardiomyocyte apoptosis through activating the p38-Sirt1-p53 signaling pathway.

Abstract
Objective: To investigate the impacts of antenatal anxiety on preterm birth and low birth weight. Methods: Women in early pregnancy were recruited for follow-up, antenatal anxiety in three trimesters was screened using Self-Rating Anxiety Scale and the score ≥50 was regarded as anxiety. Logistic regression analysis was conducted to evaluate the associations of the anxiety in three trimesters, new onset anxiety in the second and third trimesters with infant birth outcomes, such as preterm birth and low birth weight. Results: The rates of anxiety in the first, second and third trimesters of pregnancy were 12.5%, 3.7%, and 7.4% respectively. We found that there was no statistical association between anxiety in the first and second trimester and preterm birth. The anxiety in the third trimester was associated with increased odds for preterm birth (OR=3.55, 95%CI: 1.62-7.82). Associations between anxiety in all three trimesters and low birth weight were not significant. New onset anxiety in the third trimester was associated with significant increased risk of premature delivery (OR=5.20, 95%CI: 1.84-14.70) and low birth weight (OR=6.93, 95%CI: 2.42-19.88). Conclusions: Our study showed that anxiety in the third trimester is an important risk factor for premature delivery, new onset anxiety symptoms in the third trimester can significantly increase the incidence of premature birth and low birth weight of infant.

Abstract
Objective: To investigate the relationship between pregnancy-related anxiety and executive function in preschool children. Methods: From October 2008 to October 2010, pregnant women and live births were enrolled in the study. The expectant pregnant women and their live singleton fetuses were recruited from the antenatal care clinic of Ma'anshan maternal and Child Health Care Hospital. The cohort was followed up from April 2014 to June 2015. A total of 3 556 pairs of maternal and child were included in the final analysis. The questionnaire was used to collect the relevant information of pregnant women and the follow-up data of children. Pregnancy-related anxiety was assessed by using the Pregnancy-Related Anxiety Questionnaire, and the executive function of preschool children was assessed by using the Behavior Rating Inventory of Executive Function-Preschool (BRIEF) (Parent Version). Bi-nominal logistic regression was used to analyze the effect of pregnancy-related anxiety on executive function in preschool children. Results: The average age of 3 556 pregnant women was (26.78±3.42) years old, and the average age of preschool children was (4.32±0.46) years old. The proportion of primipara, only child and urban children was 94.96% (3 375/3 556), 91.37% (3 249/3 556) and 88.98% (3 164/3 556), respectively. The prevalence of pregnancy-related anxiety in the 1(st) and 3(rd) trimester was 17.60% (626/3 556) and 6.30% (224/3 556) respectively. The prevalence of abnormal global executive composite was 8.54% (304/3 556). The prevalence of anxiety in both trimesters was 7.68% (273/3 556). After controlling for confounding factors such as monthly family income, education years of parents, maternal age, pre-pregnancy weight, previous adverse pregnant outcomes, number of pregnancy, pregnant complications, the main residence of the children in the past six months, and Z score of birth weight, compared with the group without pregnancy-related anxiety in either 1(st) or 3(rd) trimester, pregnancy-related anxiety in the 1(st) trimester increased the risk of preschool children's abnormality in inhibition, working memory, planning/organization and global executive composite, and the OR (95%CI) value was 1.52 (1.08-2.13), 1.41 (1.14-1.74), 1.62 (1.13-2.33), and 1.60 (1.18- 2.17), respectively. Anxiety in the 3(rd) trimester increased the risk of children's abnormality in inhibition and global executive composite, and the OR (95%CI) value was 1.90 (1.15-3.12) and 1.69(1.05-2.71). Pregnancy-related anxiety in both trimesters increased the risk of abnormality in inhibition, working memory, planning/organization, and global executive composite in preschool children, and the OR (95% CI) value was 2.41 (1.61-3.62), 2.19 (1.66-2.88), 1.80 (1.11-2.92), and 2.41 (1.65-3.52), respectively. Conclusion: The exposure to pregnancy-related anxiety during pregnancy increases the risk of executive dysfunction in preschool children.

Abstract
OBJECTIVE This paper aims to investigate the correlation of lipid peroxide in erythrocytes and ATP (Adenosine Triphosphate) enzyme activity of erythrocyte membrane with fetal distress in patients with intrahepatic cholestasis of pregnancy (ICP). PATIENTS AND METHODS Forty-three patients with ICP treated at Jining No. 1 People's Hospital were enrolled as a study group, and another forty healthy parturient women in the same period were enrolled as a control group, to extract their elbow venous blood and fetal umbilical cord blood. Thiobarbituric acid (TBA) was used to detect superoxide dismutase (SOD) activity of erythrocytes, malondialdehyde (MDA) activity in plasma, Na+-K+-ATP enzyme activity and Ca2+-Mg2+-ATP enzyme activity of erythrocytes, which were compared between the study and control groups. The correlation of MDA, Na+-K+-ATP enzyme and Ca2+-Mg2+-ATP enzyme activities with fetal distress in the study group was analyzed, and the correlation of MDA with Na+-K+-ATP enzyme activity was investigated. RESULTS SOD and MDA activities of erythrocytes in maternal blood of the study group were significantly higher than those in the control group (p<0.05, p<0.001, respectively), but MDA activity in umbilical cord blood of the study group was markedly higher than that in the control group (p<0.001). Na+-K+-ATP enzyme and Ca2+-Mg2+-ATP enzyme activities of maternal and fetal erythrocytes of the study group were remarkably lower than those of the control group (p<0.001). MDA in the fetal distress group was significantly higher than that in the no fetal distress group in the study group (p<0.001). Na+-K+-ATP enzyme activity was negatively correlated with MDA concentration in maternal and fetal erythrocytes of patients with ICP (both p<0.001). CONCLUSIONS Lipid peroxidation in patients with ICP will affect ATP enzyme activity of erythrocyte membrane, and the down-regulation of ATP enzyme activity in umbilical cord blood of patients with ICP may cause fetal distress in the uterus.

Abstract
BACKGROUND Hyperthermic intraperitoneal chemotherapy (HIPEC) has been shown to be an effective treatment for peritoneal tumors; whether preventive HIPEC after radical resection for T4 stage colon adenocarcinoma could decrease peritoneal recurrence remains unknown. The aim of the present study was to compare peritoneal recurrence and short-term survival in patients with T4 stage colon adenocarcinoma undergoing HIPEC plus adjuvant chemotherapy or adjuvant chemotherapy alone following surgery. METHODS We retrospectively reviewed T4 stage colon adenocarcinoma patients who had radical tumor resection at our institution between January 2014 and January 2019. Clinical data were extracted from the database at our institution, and patient survival and long-term complications were assessed through repeated outpatient examinations and telephone interviews. RESULTS A total of 352 patients were included in this study; 157 patients received postoperative HIPEC plus adjuvant chemotherapy (HIPEC group), 195 patients received adjuvant chemotherapy alone (conventional chemotherapy group). Forty-one (26.1%) patients in the HIPEC group had a peritoneal recurrence and the peritoneum was the first site of tumor recurrence in 6 (14.6%) of them. However, 73 (37.4%) patients experienced peritoneal recurrence in the conventional group, and the peritoneum was the first site of tumor recurrence in 25 (34.2%) (p = 0.019). Disease-free survival in the HIPEC group at 1 and 3 years was 93.3% and 61.1%, respectively, versus 89.3% and 51.7% in the conventional chemotherapy group (p = 0.038). Overall survival in the HIPEC group at 1 and 3 years was 100.0% and 82.7%, respectively, versus 100.0% and 76.9% in the conventional chemotherapy group (p = 0.420). The two groups did not differ with respect to severe complications. CONCLUSIONS Preventive HIPEC after radical surgery may decrease peritoneal recurrence and promote disease-free survival for T4 stage colon adenocarcinoma. Large-scale randomized controlled studies are needed to confirm the results of our study.

Abstract
Background:Hip joint lesion are the main cause of disability in patients with Ankylosing Spondylitis(AS) in western China. Seriously affect the quality of life of patients.The early clinical characteristics of hip joint disease are not typical, the disease is insidious, and the radiological diagnosis is delayed.The main prevention is early screening and early diagnosis.Objectives:This study attempted to find out the main characteristics and related factors in different groups of AS combine with hip joint lesion in western China.Methods:A-First evaluation:How many patients have 1) active SIJ changes on MRI. 2) chronic SIJ changes (each for erosion, clerosis, ankylosis, or any of those) on MRI. 3) a combination of active changes and chronic changes (each for erosion, sclerosis, ankylosis, or any of those) on MRI. 4) active hip changes on MRI. 5) chonic hip changes (erosion, effusion any of those) on MRI. 6) a combination of active changes and chronic hanges (erosion, effusion any of those) on MRI. B-Then, combination SIJ / hip. 7) active SIJ changes on MRI and in parallel active hip changes on MRI. 8) chronic (see above) SIJ changes on MRI and in parallel active hip changes on MRI. 9) chronic (see above) SIJ changes on MRI and in parallel chronic (see above) hip changes on MRI. 10) chronic (see above) SIJ changes on MRI and in parallel any (active or chronic) hip changes on MRI. C-Then, characterization of these groups with non-imaging findings. Characteristics of groups 7-10 above, for age, sex, Disease duration, Hip pain, Joint pain, enthesitis, Diarrhea, uveitis, ASDAS-CRP, BASDAI, BASFI, BASMI, Pat. Global, CRP, ESR, Harris Score, HLA-B27.Results:Retrospective analysis total 558 SpA patients (mean age 29, mean duration 5 years). 1) HIP-Active+Chronic group (N=288, AS=151) vs SIJ+HIP-Active group (N=241, AS=138): hip pain (p<0.0001), diarrhea (p<0.0001), joint pain (p<0.0001) and BASFI (p<0.05); 2) HIP-Active+Chronic(N=117, AS=58) vs SIJ-Chronic+HIP-Active group (N=214, AS=134): hip pain(p<0.0001), joint pain (p<0.0001), enthesitis (p<0.0001), ASDAS-CRP (p<0.05) and ESR (p<0.05); 3) SIJ-Active+Chronic group (N=204, AS=125) vs SIJ-Chronic+HIP-Active group (N=214, AS=134): hip pain (p<0.0001), joint pain (p<0.0001); 4) SIJ-Active+Chronic group (N=204, AS=125) vs SIJ+HIP-Chronic group (N=72, AS=40):hip pain (p<0.0001), Pat.

Abstract
Background:SpA has historically been a difficult clinical diagnosis, especially early diagnosis. Two imaging techniques that address this problem are magnetic resonance imaging (MRI) and Single-Photon Emission Computed Tomography-Computed Tomography (SPECT-CT). Their accuracies have not been adequately compared.Objectives:The purpose of this study is to compare the sensitivities and specificities of SPECT-CT and MRI in SpA.Methods:This retrospective study assessed all patients who underwent SPECT-CT of the sacroiliac joint to assess for SpA. The results of SPECT-CT were compared against MRI for all patients in the cohort who underwent an MRI within 4 weeks of the SPECT-CT. A diagnosis of SpA in the discharge summary was considered the reference standard, and was based on a combination of clinical scenario, response to therapy, imaging,, patient history or lab index.Results:200 patients (173 men; average 22±4 years of age) were included SpA was diagnosed in 189 (AS patients=99 and excluded in 11. SPECT-CT and MRI had similar (P >0 .05;k ¼ 0.74) sensitivities (0.94 vs 0.94),specificities (1.00 vs 1.00),positive predictive values (1.00 vs 1.00),negative predictive values (0.94 vs 0.80),and accuracies (0.97 vs 0.95) when compared to the reference standard.Conclusion:Although MRI remains the initial modality of choice in early diagnosing SpA, SPECT-CT appears diagnostically equivalent and should be considered a viable supplementary or alternative imaging modality particularly if there is contra-indication or inaccessibility to MRI.References:[1]Taurog J D, Chhabra A, Colbert R A.
