Abstract
Nanoscale vesicles such as synaptic vesicles play a pivotal role in efficient interneuronal communications in vivo. However, the coexistence of single vesicle and vesicle clusters in living cells increases the heterogeneity of vesicle populations, which largely complicates the quantitative analysis of the vesicles. The high spatiotemporal monitoring of vesicle assemblies is currently incompletely resolved. Here, this work uses synthetic vesicles and DNA nanorulers to reconstruct in vitro the vesicle assemblies that mimic vesicle clusters in living cells. DNA nanorulers program the lateral distance of vesicle assemblies from 3 to 10 nm. This work uses the carbon fiber nanoelectrode (CFNE) to amperometric monitor artificial vesicle assemblies with sub-10 nm interspaces, and obtain a larger proportion of complex events. This work resolves the heterogeneity of individual vesicle release kinetics in PC12 cells with the temporal resolution down to ≈0.1 ms. This work further analyzes the aggregation state of intracellular vesicles and the exocytosis of living cells with electrochemical vesicle cytometry. The results indicate that the exocytosis of vesicle clusters is critically dependent on the size of clusters. This technology has the potential as a tool to shed light on the heterogeneity analysis of vesicle populations.

Abstract
OBJECTIVE To investigate the expression of neutrophil extracellular traps (NETs) and phagocytic function in the peripheral blood of patients with hepatic alveolar echinococcosis (HAE), and to examine their correlations with clinical inflamma tory indicators and liver functions. METHODS A total of 50 patients with HAE admitted to Department of Hepatobiliary and Pancreatic Surgery, The Affiliated Hospital of Qinghai University from August 2022 to June 2023 were enrolled, while 50 age- and gender-matched healthy individuals from the Centre for Healthy Examinations of the hospital during the same period served as controls. The levels of NETs markers neutrophil myeloperoxidase (MPO) and neutrophil elastase (NE) were measured using enzyme-linked immunosorbent assay (ELISA). Peripheral blood neutrophils were isolated using density gradient centrifugation, stimulated in vitro using phorbol 12-myristate 13 acetate (PMA), and the levels of MPO and citrullination histone H3 (CitH3) released by neutrophils were quantified using flow cytometry. The phagocytic functions of neutrophils were examined using flow cytometry. In addition, the correlations of MPO and NE levels with clinical inflammatory indicators and liver biochemical indicators were examined using Spearman correlation analysis among HAE patients. RESULTS The peripheral blood plasma MPO[(417.15 ± 76.08) ng/mL vs. (255.70 ± 80.84) ng/mL; t = 10.28, P < 0.05], NE[(23.16 ± 6.75) ng/mL vs. (11.92 ± 3.17) ng/mL; t = 10.65, P < 0.05]and CitH3 levels[(33.93 ± 18.93) ng/mL vs. (19.52 ± 13.89) ng/mL; t = 4.34, P < 0.05]were all significantly higher among HAE patients than among healthy controls, and a lower phagocytosis rate of neutrophils was detected among HAE patients than among healthy controls[(70.85 ± 7.32)% vs. (94.04 ± 3.90)%; t = 20.18, P < 0.05], and the ability to produce NETs by neutrophils was higher among HAE patients than among healthy controls following in vitro PMA stimulation. Pearson correlation analysis showed that the phagocytosis rate of neutrophils correlated negatively with platelet-to-lymphocyte ratio (PLR), neutrophil-to-lymphocyte ratio (NLR), interleukin-6 (IL-6) level and C-reactive protein (CRP) level (rs = -0.515 to -0.392, all P values < 0.05), and the MPO and NE levels positively correlated with inflammatory markers NLR, PLR, CRP and IL-6 (rs = 0.333 to 0.445, all P values < 0.05) and clinical liver biochemical indicators aspartic transaminase, alanine aminotransferase, direct bilirubin and total bilirubin among HAE patients (rs = 0.290 to 0.628, all P values < 0.001). CONCLUSIONS Excessive formation of NETs is found among HAE patients, which affects the phagocytic ability of neutrophils and results in elevated levels of inflammatory indicators. NETs markers may be promising novel biomarkers for early diagnosis, monitoring, and severity assessment of liver disease.

Abstract
BACKGROUND Immune and inflammatory responses have a pivotal role in the pathogenesis of rheumatoid arthritis (RA) and atherosclerotic cardiovascular disease (ASCVD). This study aims to explore the change of peripheral lymphocytes, especially the absolute and relative changes in peripheral T cells in RA patients with and without ASCVD. HYPOTHESIS The changes in the lymphocyte subsets were assessed to provide a novel insight in diagnosing and preventing ASCVD in patients with RA. METHODS A propensity score matching system (1:1) was conducted to perform a matched case-control study with 169 pairs RA-ASCVD and RA participants. Univariate and multivariate analyses were performed to determine the association between peripheral lymphocytes and RA-ASCVD. RESULT Multivariate logistic regression analysis demonstrated that Th17 cell absolute, Th17 cell Ratio, Th17/Treg were associated with a significantly higher risk of ASCVD after model adjustment. Then we focused on Th17/Treg, multivariate logistic analyses in tri-sectional Th17/Treg groups showed that the odds of ASCVD is gradually increasing with Th17/Treg rank's rising after model adjustment. Finally, the restricted cubic spline of Th17/Treg and odds ratio of RA-ASCVD was conducted. Interestingly, we found a critical point of Th17/Treg (critical point = 0.2399). Th17/Treg shows a protective role in the odds of ASCVD when Th17/Treg < 0.2399. With smaller Th17/Treg, the protective efficiency is more obvious when Th17/Treg < 0.2399. CONCLUSIONS Our study suggested that increasing absolute and percentage of Th17 cells in the peripheral blood of patients with RA was associated with the development of ASCVD. And Th17/Treg may be a promising biomarker for patients with RA in indicating comorbidity with ASCVD.

Abstract
Rapid detection of prostate-specific antigen (PSA) is pivotal for the early screening of prostate cancer (PCa). Here, we devise a one-step, amplification-free fluorescent detection strategy for PSA, employing the trans-cleavage principle of a CRISPR-Cas12a-aptamer system. This method offers a linear range of 0.31-5 ng mL-1 and a detection limit of 0.16 ng mL-1. The high-confidence quantification of PSA is demonstrated through the analysis of real samples, effectively distinguishing between PCa patients and healthy individuals.

Abstract
BACKGROUND Obstructive sleep apnea (OSA) affects the occurrence of atrial fibrillation (AF) and usually coexists with AF. Chronic inflammation has been identified as an important factor in the development of AF, and the neutrophil-to-lymphocyte ratio (NLR) has been identified as a biomarker that positively correlates with the degree of inflammation. However, little information regarding how NLR correlates with AF in OSA patients. METHODS Our study enrolled 368 patients with OSA between September 2018 and April 2023. All data were collected after admission. Independently associated factors were assessed by multivariate logistic regression and then constructed a nomogram to predict AF risk. Nomogram's calculation model was evaluated using receiver operating characteristic (ROC) curves, calibration curves, and decision curve analysis (DCA). The correlation between CHA2DS2-VASc scores and NLR was assessed using Spearman correlation. RESULTS Multivariate logistic regression showed that high level log-transformed NLR (OR, 1.664; 95% CI, 1.026-2.699; P = 0.039) was independently associated with the presence of AF in patients with OSA. The concordance index (0.817, 95% CI, 0.770-0.864), ROC curve, calibration curve, and DCA of the nomogram indicated this model had well clinical utility. Also, the nomogram's calculation model could identify patients who are at a higher risk of developing AF, and the CHA2DS2-VASc score was positively correlated with NLR in patients with AF (P < 0.05). CONCLUSION The elevated NLR may serve as a promising biomarker for assessing the risk of AF in individuals with OSA. The nomogram's calculation model may be utilized as a tool to estimate the probability of AF occurrence in OSA patients.

Abstract
The global spread of air-borne diseases, such as Covid-19 caused by the new coronavirus (SARS-CoV-2), has significantly impacted public health and economic development worldwide. Accurate and rapid detection of pathogens is the key to controlling the spread of infection and reducing severe illness and death. Compared to nucleic acid testing, rapid antigen testing for pathogen proteins shows unique advantages such as convenience, speed, and cost-effectiveness, but its sensitivity is limited. Here, we review the latest progress in the development of immunological assay methods for infectious diseases. We summarize the principles, performance, advantages and limitations of several representative methods. We highlight recent efforts in utilizing nanotechnology to engineer biosensing interfaces, offering enhanced sensitivity while maintaining convenience for on-site diagnosis. Finally, we provide an outlook on the development of this field.

Abstract
A Mediterranean-style diet (MED) can promote people lengthen the span of life and avoid atherosclerotic cardiovascular disease (ASCVD) in primary prevention. Metabolic syndrome (MetS) can significantly reduce life expectancy and increase the risk of ASCVD. However, few studies have focused on the role of the Mediterranean diet in patients with MetS. Participants in the National Health and Nutrition Examination Survey (NHANES) with MetS (N = 8301) from 2007 to 2018 were examined. A 9-point evaluation scorewas used to measure the degree of adherence to the MED diet. In order to compare the various levels of adherence to the MED diet and the effects of the specific MED diet components on all-cause and cardiovascular mortality, Cox regression models were utilized. Among the 8301 participants with MetS, about 13.0% (1080 of 8301) died after a median follow-up of 6.3 years. In this study, participants with MetS with adherence to high-quality and moderate-quality Mediterranean diet were significantly associated with lower all-cause mortality as well as cardiovascular mortality during the follow-up period. Futhermore, in joint analysis of the Mediterranean diet and sedentary behavior or depression, we found that high-quality or moderate-quality Mediterranean diet could attenuate, even reverse the adverse effects of sedentary behavior and depression on all-cause and cardiovascular mortality in participants with MetS. Among the components of the MED diet, greater intakes of vegetables, legumes, nuts and high MUFA/SFA ratio were significantly associated with lower all-cause mortality and greater vegetables intake was significantly associated with lower cardiovascular mortality, while more red/processed meat intake was significantly associated with higher cardiovascular mortality in participants with MetS.

Abstract
BACKGROUND There is a bidirectional effect between sleep disorders and Mediterranean diet (MED), but the joint effect of MED and sleep disorders on mortality is unclear. The aim of this study was to investigate whether there is a synergistic effect of adherence to MED and sleep disorders on all-cause and cause-specific mortality. METHODS The study included 23,212 individuals in the National Health and Nutrition Examination Survey (NHANES) from 2005 to 2014. A 9-point evaluation score, alternative Mediterranean diet (aMED) index was used to assess adherence to MED. Sleep disorder and hours of sleep were assessed by structured questionnaires. Cox regression models were used to assess the relationship between sleep disorders, aMED and all-cause mortality, cause-specific mortality (cardiovascular-related death, cancer-related death). The interaction effect of sleep disorders with aMED on mortality was further assessed. RESULTS Results showed that participants with lower aMED and presence of sleep disorders had significantly higher risk of all-cause mortality and cardiovascular-related mortality (HR, 2.16, 95% CI, 1.49-3.13, P < 0.0001; HR, 2.68, 95% CI, 1.58-4.54, P = 0.0003). A significant interaction effect was found between aMED and sleep disorders on cardiovascular mortality (p for interaction = 0.033). No significant interaction existed between aMED and sleep disorders on all-cause mortality (p for interaction = 0.184) and cancer-related mortality (p for interaction = 0.955). CONCLUSIONS Poorer adherence to MED and sleep disorders synergistically increased long-term all-cause mortality and cardiovascular mortality in NHANES population.

Abstract
One of the most prevalent cardiac diseases is cardiac arrhythmia, however the underlying causes are not entirely understood. There is a lot of proof that gut microbiota (GM) and its metabolites have a significant impact on cardiovascular health. In recent decades, intricate impacts of GM on cardiac arrythmia have been identified as prospective approaches for its prevention, development, treatment, and prognosis. In this review, we discuss about how GM and its metabolites might impact cardiac arrhythmia through a variety of mechanisms. We proposed to explore the relationship between the metabolites produced by GM dysbiosis including short-chain fatty acids(SCFA), Indoxyl sulfate(IS), trimethylamine N-oxide(TMAO), lipopolysaccharides(LPS), phenylacetylglutamine(PAGln), bile acids(BA), and the currently recognized mechanisms of cardiac arrhythmias including structural remodeling, electrophysiological remodeling, abnormal nervous system regulation and other disease associated with cardiac arrythmia, detailing the processes involving immune regulation, inflammation, and different types of programmed cell death etc., which presents a key aspect of the microbial-host cross-talk. In addition, how GM and its metabolites differ and change in atrial arrhythmias and ventricular arrhythmias populations compared with healthy people are also summarized. Then we introduced potential therapeutic strategies including probiotics and prebiotics, fecal microbiota transplantation (FMT) and immunomodulator etc. In conclusion, the GM has a significant impact on cardiac arrhythmia through a variety of mechanisms, offering a wide range of possible treatment options. The discovery of therapeutic interventions that reduce the risk of cardiac arrhythmia by altering GM and metabolites is a real challenge that lies ahead.

Abstract
Objective: To understand the infection status of Enterovirus (EV) in cases of acute respiratory infections (ARIs) in Luohe City, Henan Province from 2017 to 2021, and analyze the prevalence and type composition of EV in ARIs. Methods: From October 2017 to May 2021, pharyngeal swab samples were collected from 1 828 patients with ARIs in Luohe Central Hospital and the clinical epidemiological data of these cases were also collected. EV-positive samples were identified by Quantitative Real-time Polymerase Chain Reaction (qPCR). The 5'-untranslated region (5'UTR) was amplified by Reverse Transcription-Polymerase Chain Reaction (RT-PCR). The results of 5'UTR region were initially typed by Enterovirus Genotyping Tool Version 1.0. Based on the typing results, the full-length of VP1 region was amplified by RT-PCR. The EV typing was identified again by VP1 region. Results: Among 1 828 cases of ARIs, 56.7% (1 036) were males. The median (Q1, Q3) age was about 3 (1, 5) years. Patients under 5 years old accounted for 71.6% (1 309 cases). Among all cases, a total of 71 EV-positive samples were identified by qPCR, with a detection rate of 3.88% (71/1 828). The EV detection rates for men and women were 3.28% (34/1 036) and 4.67% (37/792), without statistically significant differences (χ2=2.32, P=0.14). The EV detection rates for 2 to <6 years, 6 months to <2 years, 6 to <10 years, and <6 months were 6.29% (48/763), 3.00% (18/600), 2.52% (4/159), and 1.67% (1/60) (χ2=27.91, P<0.001). The EV detection rate was 0.92% (3/326) in autumn and winter of 2017. The EV detection rates were 1.18% (6/508), 2.47% (12/485) and 8.31% (34/409) in each year from 2018 to 2020, with an increasing trend year by year(χ2trend=29.76, P<0.001). The main prevalent seasons were summer and autumn. The detection rate in spring of 2021 was 4.00% (4/100). A total of 12 types were identified and classified as CVA2, CVA4, CVA5, CVA6, CVA10, CVB3, CVB5, E5, E11, E30, PV-1, and EV-D68. The types of CVA2, CVA10, CVA6, and CVB3 were the dominant phenotypes. In 59 sample of EV typing, the main clinical manifestation was upper respiratory tract infection (36/59, 61.01%). The dominant types detected in upper respiratory tract infections were CVA10 (10/36, 27.78%), CVA6 (9/36, 25.00%) and CVB3 (8/36, 22.22%). The dominant type detected in lower respiratory tract infections was CVA2 (7/19, 36.84%). Conclusion: In Luohe City, Henan Province from 2017 to 2021, EV infection in ARIs cases has clear seasonal and age-specific patterns, and the dominant types of upper and lower respiratory tract infections are different.

Abstract
BACKGROUND Accumulating evidence suggests that patients with nonalcoholic fatty liver disease (NAFLD) have a significantly high risk of incident atrial fibrillation (AF). Systemic inflammation, metabolic disorders and oxidative stress could be the potential mechanisms by which NAFLD drives AF. Monocyte-to- high-density lipoprotein ratio (MHR) has emerged as a novel biomarker of inflammation and oxidative stress that has not been studied in AF with NAFLD patients. We aimed to investigate the relationship between MHR and the risk of AF among NAFLD patients. METHODS A retrospective analysis was performed for the clinical data of the patients with NAFLD in the Second Hospital of Shanxi Medical University from January 2019 to October 2022, among whom 204 patients with AF were enrolled as NAFLD+AF group and 613 patients without AF were enrolled as NAFLD control, and 152 patients were selected from each group based on propensity score matching (PSM) at a ratio of 1:1 to balance the covariates between groups. The t-test or the Mann-Whitney U test was used for comparison of continuous data between two groups; the chi-square test or the Fisher's exact test was used for comparison of categorical data between two groups. Logistic regression analysis was performed to identify the independent predictor for occurrence of AF among NAFLD patients. Trend chi-square test to analyze the prevalence of AF among MHR tertiles, and then the correlation between MHR and the risk of AF confirmed by restricted cubic splines (RCS). The receiver operating characteristic (ROC) curve analysis was used to determine the optimum MHR cutoff value to predict AF. RESULTS Univariate analysis showed that AF patients had higher MHR than non-AF patients (P < 0.001). Meanwhile, compared with pure NAFLD patients, multivariate logistic regression analysis showed that MHR remained to be an independent risk factor for AF after adjusting for confounding risk factors (OR = 10.67, 95% CI 2.17-52.37, P = 0.004). TC、HDL-C were also independent risk factors for AF. Among them, TC and HDL-C are protective factors for AF. The trend chi-square test showed that the risk of AF increased with an increase in MHR (P < 0.05). However, the RCS showed a nonlinear and J-shaped relationship between MHR and the risk of AF (P for non-linearity = 0.023). The occurrence of AF increased with increasing MHR only when MHR > 0.44. The ROC curve showed that MHR combined with traditional risk factors can improve the ability to predict AF. CONCLUSION MHR is an independently associated with incident AF in patients with NAFLD and show a certain predictive value.

Abstract
Background The left atrial low-voltage areas (LVAs) are associated with atrial fibrosis; however, it is not clear how the left atrial LVAs affect the recurrence of arrhythmias after catheter ablation, and the efficacy and safety of the left atrial substrate modification based on LVAs as a strategy for catheter ablation of atrial fibrillation (AF) are not evident for AF patients with LVAs. Methods We performed a systematic search to compare the arrhythmia recurrence in AF patients with and without LVAs after conventional ablation and arrhythmia recurrence in LVAs patients after conventional ablation with and without substrate modification based on LVAs. Result A total of 6 studies were included, involving 1,175 patients. The arrhythmia recurrence was higher in LVA patients after conventional ablation (OR: 5.14, 95% CI: [3.11, 8.49]; P < 0.00001). Additional LVAs substrate modification could improve the freedom of arrhythmia in LVAs patients after the first procedure (OR: 0.30, 95% CI: [0.15, 0.62]; P = 0.0009). However, there was no significant difference after multiple procedures (P = 0.19). The procedure time (MD: 26.61, 95% CI [15.79, 37.42]; P < 0.00001) and fluoroscopy time (MD: 6.90, 95% CI [4.34, 9.47]; P < 0.00001) in LVAs patients with additional LVAs substrate modification were significantly increased compared to LVAs patients’ without substrate modification. Nevertheless, there were no higher LVAs substrate modification-related complications (P = 0.93) between LVAs patients with and without additional LVAs substrate modification. In the subgroup analysis, the additional LVAs substrate modification reduced the risk of arrhythmia recurrence in LVAs patients during the follow-up time, which was 12 months (OR: 0.32, 95% CI (0.17, 0.58); P = 0.002), and box isolation (OR: 0.37, 95% CI (0.20, 0.69); P = 0.002) subgroups, but the type of AF, follow up >12 months and homogenization subgroups were not statistically significant. Trial sequential analysis shows conclusive evidence for the LVAs ablation. Conclusion This study has shown that LVAs could improve the risk of arrhythmia recurrence in AF patients after conventional ablation. And additional LVAs substrate modification after conventional ablation could increase the freedom of arrhythmia recurrence in LVAs patients. Interestingly, the box isolation approach appeared more promising. Systematic review registration [http://www.crd.york.ac.uk/prospero], identifier [CRD42021239277].

Abstract
Helminth infections may trigger host innate and adaptive immune responses. Group 2 innate lymphoid cells (ILC2) are an important factor involved in type 2 immune responses, and produce a large number of T helper 2 cell (Th2) cytokines following stimulation by interleukin (IL)-25, IL-33 and thymic stromal lymphopoietin (TSLP), which play a critical role in parasite clearance and tissue repair. Following helminth infections, autocrine factors, mast cells, enteric nervous system and Th2 cells have been recently found to be involved in regulation of ILC2. Unraveling the role of ILC2 in immune response against helminth infections is of great value for basic research and drug development. This review summarizes the research progress on ILC2 and its role in helminth infections.

Abstract
OBJECTIVE To investigate the value of HBV RNA for predicting the therapeutic effect of long-term entecavir (ETV) antiviral therapy in patients with chronic hepatitis B (CHB). METHODS Serum samples were collected from 59 CHB patients treated with ETV for 96 or 108 months. HBV RNA levels, HBV DNA levels, and serological marker (HBeAg) levels were measured at baseline and 3, 6, 9, 12, 36, 72, and 96 (or 108) months during the therapy. RESULTS Although HBV RNA level decreased after 12 and 36 months of ETV antiviral therapy, no significance changes occurred in HBV RNA negative conversion rate (P>0.05). After 72 months of treatment or longer, 33 patients had HBV RNA levels lower than 100 copies/mL, and among them 29 patients had HBV RNA levels lower than the detection limit, and HBV RNA negative conversion rate was statistically significant (P < 0.05). A lower HBV RNA level was associated with a higher HBeAg negative conversion rate (P < 0.05). Age and HBV RNA level were positively correlated with HBeAg negative conversion rate (P < 0.05). CONCLUSION Prolonged ETV antiviral therapy results in better clearance of HBV RNA and a higher negative conversion rate in CHB patients. The length of antiviral therapy and age are positively correlated with the negative conversion rate of HBV RNA, and earlier administration of the antiviral treatment achieves better therapeutic effect. Serum HBV RNA level can be used as an indicator for predicting conversion to negative HBeAg in CHB patients receiving ETV therapy.

Abstract
Background Insulin resistance (IR), endothelial dysfunction, inflammation, glucose and lipid metabolism disorders, and thrombosis are believed involved in coronary heart disease (CHD) and non-alcoholic fatty liver disease (NAFLD). Triglyceride-glucose (TyG) index, a new IR indicator, is correlated with NAFLD occurrence and severity, but its relationship with CHD risk remains unclear. This study investigated the correlation between TyG index and CHD risk among NAFLD patients. Methods This cross-sectional study included 424 patients with NAFLD and chest pain in the Department of Cardiology, The Second Hospital of Shanxi Medical University, from January 2021 to December 2021. The TyG index was calculated and coronary angiography performed. All individuals were divided into NAFLD + CHD and NAFLD groups and then by TyG index level. The t-test, Mann–Whitney U-test, or one-way analysis of variance compared differences in continuous variables, while the chi-square test or Fisher’s exact test compared differences in categorical variables. Logistic regression analysis determined the independent protective or hazardous factors of NAFLD with CHD. The receiver operating characteristic curve evaluated the ability of different TyG index rule-in thresholds to predict CHD. The relationship between Gensini score and TyG index was evaluated using linear correlation and multiple linear regression. Results CHD was detected in 255 of 424 patients. Compared to NAFLD group, multivariate logistic regression showed that TyG index was a risk factor for CHD among NAFLD patients after adjustment for age, sex, hypertension, and diabetes mellitus with the highest odds ratio (OR, 2.519; 95% CI, 1.559–4.069; P < 0.001). TG, low-density lipoprotein cholesterol, FBG and TYG–body mass index were also risk factors for CHD among NAFLD patients. High-density lipoprotein cholesterol level was a protective factor for CHD events in patients with NAFLD. In an in-depth analysis, multivariate logistic regression analysis showed that each 1-unit increase in TyG index was associated with a 2.06-fold increased risk of CHD (OR, 2.06; 95% CI, 1.16–3.65; P = 0.013). The multifactor linear regression analysis showed each 0.1-unit increase in TyG in the NAFLD-CHD group was associated with a 2.44 increase in Gensini score (β = 2.44; 95% CI, 0.97–3.91; P = 0.002). Conclusions The TyG index was positively correlated with CHD risk in NAFLD patients and reflected coronary atherosclerosis severity.

Abstract
Pulsed-power generators can produce well-controlled continuous ramp compression of condensed matter for high-pressure equation-of-state studies using the magnetic loading technique. X-ray diffraction (XRD) data from dynamically compressed samples provide direct measurements of the elastic compression of the crystal lattice, onset of plastic flow, strength-strain rate dependence, structural phase transitions, and density of crystal defects, such as dislocations. Here, we present a cost-effective, compact, pulsed x-ray source for XRD measurements on pulsed-power-driven ramp-loaded samples. This combination of magnetically driven ramp compression of materials with a single, short-pulse XRD diagnostic will be a powerful capability for the dynamic materials' community to investigate in situ dynamic phase transitions critical to equation of states. We present results using this new diagnostic to evaluate lattice compression in Zr and Al and to capture signatures of phase transitions in CdS.

Abstract
Objective: To understand the incidence trend of liver cancer in China from 2005 to 2016, and explore the correlation between the incidence trend of liver cancer and the incidence trend of hepatitis B. Methods: The incidence data of liver cancer in China from 2005 to 2016 were collected from the Annual Report of Cancer Registry in China. The incidence data of hepatitis B were collected from China Public Health Science Data Center. World standardized incidence rate (WSR) was calculated according to the World Segi's population. Joinpoint regression model was used to analyze the trend of WSR of liver cancer [measured by average annual percentage change (AAPC)]. The age-period-cohort model was fitted to analyze the age, period and cohort effects in people aged 20- years and above. Pearson correlation coefficient was used to explore the correlation between the incidence of liver cancer and the incidence of hepatitis B. Results: The crude incidence of liver cancer in China showed a trend of first increase before 2009 and then relatively stable. The world standardized morbidity rate of liver cancer in China decreased from 19.11 per 100 000 in 2005 to 17.74 per 100 000 in 2016 (AAPC=-0.5%, 95%CI: -1.3%-0.3%, P=0.240). The incidence of liver cancer in male decreased significantly (AAPC=-1.0%, 95%CI: -1.5%--0.5%, P=0.001). The incidence of liver cancer in women increased from 2005 to 2010 [annual percentage change (APC)=1.7%, 95%CI: -0.1%-3.4%, P=0.059] but showed a significant decrease trend from 2010 to 2016 (APC=-1.6%, 95%CI: -2.3%--1.0%, P=0.001). From 2005 to 2016, the incidence of liver cancer showed a decreasing trend in urban areas (AAPC=-0.3%, 95%CI: -0.8%-0.3%, P=0.316) and rural areas (AAPC=-3.9%, 95%CI: -4.4%--3.3%, P<0.001). Risk for liver cancer increased with age, while the period effect showed a trend of first increase then decrease and cohort effect showed a decrease trend. The morbidity rates of both hepatitis B and liver cancer showed decrease trends from 2009 to 2016, and there was a significant correlation (r=0.71, 95%CI: 0.01-0.94, P=0.048). Conclusions: From 2005 to 2016, the morbidity rate of liver cancer in China showed a decrease trend, and there were significant gender and urban-rural area specific differences. Age effect had a great impact on the risk for liver cancer. With the progress of population aging in China, liver cancer is still a public health problem, to which close attention needs to be paid.

Abstract
BACKGROUND Stress hyperglycemia has served as a reliable biomarker to predict poor outcomes after ischemic stroke. However, recent studies have reported some contrary conclusions. Different stroke subtypes may respond inconsistently to stress hyperglycemia. The progression of intracranial atherosclerotic stenosis (ICAS) is tightly related to hyperglycemia. Thus, this study aims to determine the relationship between stress hyperglycemia and recurrent stroke in ischemic stroke patients with or without intracranial atherosclerotic stenosis. METHODS This is a multicenter retrospective observational cohort study. Patients with acute minor ischemic stroke and eligible computed tomography and magnetic resonance imaging data were enrolled. The severity of stress hyperglycemia is measured by the stress hyperglycemia ratio (SHR). SHR was calculated based on fasting plasma glucose (FPG) and hemoglobin A1c (HbA1c) levels. The primary outcome was stroke recurrence during hospitalization. The interaction of SHR levels with the presence of ICAS on the primary outcome was investigated using univariable and multivariable Cox proportional hazards models. Restricted cubic splines were applied to determine the nonlinear relationship between SHR and primary outcome. A two-piecewise linear regression model was used to identify the threshold of SHR. RESULTS A total of 610 participants were included in the study. The average age of the patients was 61.4 ± 12.9 years old, and approximately 70% of participants were males. A total of 189 (30.98%) patients had ICAS. The patients were categorized into 3 groups based on the tertiles of SHR. Compared with the group with a lower SHR, a higher SHR was significantly associated with the risk of stroke recurrence in the ICAS group (hazard ratio [HR], 8.52, 95% confidence interval [CI], 3.16-22.96, P<0.001). When SHR was treated as a continuous variable, each 0.1-unit increase in SHR in the ICAS group was associated with a 1.63-fold increase in the risk of recurrence (HR, 1.63, 95% CI, 1.39-1.9, P<0.001) with a threshold of 0.75. FPG but not HbA1c was associated with stroke recurrence in ICAS patients (HR, 1.17, 95% CI, 1.08-1.26, P<0.001). Sensitive analyses showed consistent results after adjusting for previous diabetes mellitus, oral hypoglycemic agents and insulin injection. CONCLUSIONS SHR represents a better biomarker to predict the risk of stroke recurrence in patients with ICAS than FPG and HbA1c regardless of previous diabetes mellitus.

Abstract
Objective: To investigate the effect of N-trimethyl chitosan-recombinant tissue factor pathway inhibitor (rTFPI) complex on avulsion flap with roll compaction in rat. Methods: The experimental methods were adopted. The N-trimethyl chitosan-rTFPI complex solution was prepared by ion cross-linking method. The morphology of the complex was observed by scanning electron microscope, and its diameter was measured. The encapsulation rate of rTFPI in the complex and drug loading rate of the complex was determined and calculated by enzyme-linked immunosorbent assay (ELISA) method (n=3). The concentration of rTFPI in the solution at 0, 10, 30, 45, 60, 90, 120, 240 minutes of storage was measured by ELISA method to observe the release of rTFPI, and its half-life was calculated (n=3). Twenty-four 6-week-old male Sprague-Dawley rats were divided into phosphate buffered saline (PBS) group, N-trimethyl chitosan alone group, rTFPI alone group, and N-trimethyl chitosan-rTFPI group according to the random number table, with 6 rats in each group. The avulsion flaps with roll compaction were prepared on the backs of rats with pedicles located on the line of the bilateral iliac spine and lifted from the surface of the muscle membrane. One injection of corresponding reagents was carried out immediately after in-situ suture and on post operation day (POD) 1, 2, and 3. General changes of the flap were observed on POD 1, 3, and 7. On POD 7, the survival area of the flap was measured and the survival rate of the flap was calculated; the flaps were divided into pedicle, proximal, middle, and distal segments, and the blood perfusion in the proximal, middle, and distal segment tissue of the flap was detected by the laser speckle blood flow imager; tissue samples in the middle of the flap were cut and stained with hematoxylin and eosin to observe the changes in tissue structure and the infiltration of inflammatory cells, and the numbers of embolized blood vessels and new blood vessels per 100 times visual field were counted. Data were statistically analyzed with one-way analysis of variance and least significant difference test. Results: The N-trimethyl chitosan-rTFPI complex had an irregular spherical structure with a diameter of 150-200 nm. The encapsulation rate of rTFPI in the complex and drug loading rate of the complex were (88.7±2.1)% and (2.83±0.09)%, respectively. The concentration of rTFPI in the solution of the N-trimethyl chitosan-rTFPI complex gradually increased with prolonged storage time, and the release was basically stable at 90 min, with half-life of (651±36) min. On POD 1, the distal parts of flaps of rats in N-trimethyl chitosan alone group darkened significantly. On POD 3, scabs and necrosis were relatively mild on the distal segment of the flaps of rats in rTFPI alone group and N-trimethyl chitosan-rTFPI group as compared with those of the other two groups. On POD 7, the necrosis boundaries of the flaps of rats in each group were clear. On POD 7, the flap survival rates of rats in rTFPI alone group and N-trimethyl chitosan-rTFPI group were (63±7)% and (73±5)%, respectively, which were significantly higher than (41±3)% in PBS group and (52±7)% in N-trimethyl chitosan alone group. Moreover, the flap survival rate of rats in N-trimethyl chitosan-rTFPI group was significantly higher than that in rTFPI alone group (P<0.05). On POD 7, the flaps of rats in each group had blood perfusion; the blood perfusion values in the proximal segment tissue of the rat flaps in N-trimethyl chitosan alone group and the blood perfusion values in the proximal, middle, and distal segment tissue of the rat flaps in rTFPI alone group and N-trimethyl chitosan-rTFPI group were significantly higher than those in PBS group (P<0.05 or P<0.01); the blood perfusion values in the distal segment tissue of the rat flaps in rTFPI alone group and the blood perfusion values in the middle and distal segment tissue of the rat flaps in N-trimethyl chitosan-rTFPI group were significantly higher than those in N-trimethyl chitosan alone group (P<0.05 or P<0.01); the blood perfusion value in the middle segment tissue of the rat flaps in N-trimethyl chitosan-rTFPI group was significantly higher than that in rTFPI alone group (P<0.01). On POD 7, inflammatory cells infiltrated more and cell edema was obvious in the middle segment tissue of the rat flaps in PBS group and N-trimethyl chitosan alone group. Compared with those of the previous two groups, the inflammation degrees in the middle segment tissue of the rat flaps in rTFPI alone group and N-trimethyl chitosan-rTFPI group were significantly milder, the number of embolized blood vessels was significantly decreased (P<0.05 or P<0.01), and the number of new blood vessels was significantly increased (P<0.05 or P<0.01). Compared with that of rTFPI alone group, the number of new blood vessels in the middle segment tissue of the rat flaps in N-trimethyl chitosan-rTFPI group increased significantly (P<0.05). Conclusions: The effect of sustained release of rTFPI can be achieved by loading rTFPI with N-trimethyl chitosan. Compared with rTFPI alone, the N-trimethyl chitosan-rTFPI complex can further improve the blood perfusion of the avulsion flaps with roll compaction in rat and improve the survival rate of the flap.

Abstract
Patients with rheumatoid arthritis (RA) have a significantly high risk of atrial fibrillation (AF). This study aimed to compare the absolute and relative changes in peripheral T cells in patients with RA who were also affected with and without AF. To help make an early diagnosis and prevent the initiation and progression of AF, the changes in the lymphocyte subsets were assessed in RA patients with and without AF. A propensity score matching (PSM) system (1:3) was used to perform a matched case-control study with 40 RA-AF cases and 120 RA controls. Changes in the erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), anti-citrullinated peptide antibody (ACPA), and rheumatoid factor (RF) were examined. The percentage and absolute number of T, B, natural killer (NK), T helper (Th)1, Th2, Th17, and T-regulatory (Treg) cells in the peripheral blood of patients with and without RA-AF were determined using flow cytometry. Univariate and multivariate analyses were performed to determine the association between peripheral lymphocytes and RA-AF. Demographic data, ESR, CRP, ACPA, and the percentage, as well as the absolute value of B, NK, Th2, and Treg cells, showed no significant differences between the propensity score-matched groups of RA and RA-AF. Meanwhile, the absolute number and percentage of Th1 cells, the absolute number of Th17 cells, the ratio of Th1/Treg, Th17/Treg, and RF were significantly higher in patients with RA-AF than those in the control groups (P < 0.05). Univariate and multivariate logistic regression analyses also revealed that the percentage of Th1 cells, the absolute number of Th17 cells, and the ratio of Th1/Treg were associated with a significantly higher risk of AF. This PSM study demonstrated that the incidence of AF was higher in RA patients with Th cell immunological derangements.

Abstract
The liquid chromatography tandem mass spectrometry was used to detect the urinary proteomics of 223 residents aged 40-69 years old who participated in the National Upper Gastrointestinal Cancer Early Detection Program in Linqu County, Shandong Province from November 22 to December 7, 2018, and analyze the alcohol consumption related proteomic profiles and individual urinary protein. There were significant differences in urinary protein profiles between alcohol consumption group and non-alcohol consumption group. The expression of 26 urinary proteins was up-regulated and 20 urinary proteins were down-regulated in alcohol consumption group (P<0.05). The differentially expressed proteins had enzyme inhibitor activity and phospholipid binding function, and mainly enriched in pathways involving proximal tubule bicarbonate regeneration, complement and coagulation cascade, and cholesterol metabolism. The protein expressions of complement factor I (CFI), angiotensin converting enzyme 2 (ACE2) and protein C inhibitor (SERPINA5) were positively correlated with daily alcohol consumption.

Abstract
Objective: To study the transepidermal water loss (TEWL) of scar skin in patients with superficial scars, hypertrophic scars, and atrophic scars, and to explore the correlation between TEWL and scar severity. Methods: A retrospective observational study was conducted. From February 2017 to February 2019, 120 scar patients who met the inclusion criteria were admitted to the General Hospital of Jilin Chemical Industry Group, including 78 males and 42 females, aged (35±14) years. According to the diagnosis on admission, there were 40 cases of superficial scar patients, 40 cases of hypertrophic scar patients, and 40 cases of atrophic scar patients. On admission, the Vancouver Scar Scale (VSS) was used to score the scar of each patient; the TEWL of scar skin and normal skin 1 cm from the edge of scar or the same site of the healthy side (hereinafter referred to as normal skin) of each patient was measured by water loss tester, and the difference value of TEWL between scar skin and normal skin (hereinafter referred to as the TEWL difference) was calculated. Data were statistically analyzed with chi-square test, Kruskal-Wallis rank sum test, paired sample t test, one-way analysis of variance, and Dunnett-t test for comparison, and the correlation between the difference value of TEWL and scar VSS score was analyzed with univariate linear regression analysis. Results: On admission, the scar VSS score of superficial scar patients was significantly lower than that of hypertrophic scar or atrophic scar patients (t=4.403, 4.768, P<0.01), and the scar VSS score of atrophic scar patients was significantly lower than that of hypertrophic scar patients (t=4.185, P<0.01). On admission, the TEWL of scar skin of superficial scar, hypertrophic scar, and atrophic scar patients were (18±4), (20±4), and (20±5) g·m-2·h-1 respectively, significantly higher than (12±3), (12±3), and (14±4) g·m-2·h-1 of normal skin (t=6.889, 10.221, 5.870, P<0.01). The difference values of TEWL of superficial scar, hypertrophic scar, and atrophic scar patients were (5.9±1.7), (8.1±1.7), and (6.4±2.1) g·m-2·h-1 respectively. In comparison among different types of scar patients, only the TEWL difference of hypertrophic scar patients was significantly higher than that of superficial scar patients (t=6.975, P<0.05). The TEWL difference and the scar VSS score in patients with superficial scars, hypertrophic scars, and atrophic scars were significantly positively correlated (r=0.805, 0.872, 0.826, P<0.01). Conclusions: The TEWL of scar skin in patients with superficial scars, hypertrophic scars, and atrophic scars is increased compared with normal skin, and the degree of increase was positively correlated with the severity of scars.

Abstract
OBJECTIVE To investigate the role of PI3K/Akt signaling pathway in mediating the protective effect of endomorphin-1 against myocardial ischemia-reperfusion (IR) injury. OBJECTIVE Fifty SD male rats were randomly divided into sham operation group, myocardial IR group, endomorphin-1 post-treatment group (EM50 group), endomorphin-1+wortmannin (a PI3K/Akt signaling pathway inhibitor) treatment group (EM50+Wort group), and wortmannin treatment group (Wort group). Rat models of myocardial IR injury were established by ligation of the left anterior descending coronary artery for 30 min followed by reperfusion for 120 min. The heart rate and mean arterial pressure were monitored during the experiment. Plasma levels of LDH, CK-MB, cTnI, IL-6, TNF-α, SOD and MDA were measured after reperfusion. The mRNA expression of Bax and Bcl-2 was detected using RT-PCR, and the expression of apoptosis-related protein cleaved caspase-3, phosphorylated Akt protein and total Akt protein in myocardial tissue was detected using Western blotting. OBJECTIVE Myocardial IR injury significantly decreased heart rate and blood pressure of the rats in comparison with the sham operation (P < 0.05). Compared with those in the IR group, the rats in EM50 group showed significantly increased heart rate and blood pressure (P < 0.05) with decreased plasma LDH, CK-MB, cTnI, IL-6, TNF-α and MDA levels (P < 0.05), increased SOD activity (P < 0.05), increased expression of p-Akt protein and Bcl-2 mRNA (P < 0.05), and decreased expression of Bax mRNA and cleaved caspase-3 protein (P < 0.05). In EM50+Wort group, the heart rate and blood pressure were significantly lowered (P < 0.05), plasma LDH, CK-MB, cTnI, IL-6, TNF-α and MDA levels increased (P < 0.05), SOD activity decreased (P < 0.05), the expression of p-Akt protein and Bcl-2 mRNA was reduced (P < 0.05), and the expression of Bax mRNA and cleaved caspase-3 protein increased (P < 0.05) as compared with those in EM50 group. OBJECTIVE EM-1 postconditioning can regulate cardiac myocyte apoptosis and reduce myocardial IR injury in rats. The PI3K/Akt signaling pathway may play a role in mediating the myocardial protective effects of EM-1 postconditioning.

Abstract
Background:The Phase 3b/4 study ORAL Shift (NCT02831855) demonstrated sustained efficacy/safety of tofacitinib modified-release 11 mg QD following MTX withdrawal, that was non-inferior to continued tofacitinib + MTX use, in patients (pts) with moderate to severe RA who achieved LDA with tofacitinib + MTX at Week (W)24.1Objectives:To assess differences and similarities in clinical/functional responses in pts receiving tofacitinib ± MTX in ORAL Shift.Methods:In ORAL Shift, pts received open-label tofacitinib + MTX to W24; at W24, pts who achieved CDAI LDA were randomised to receive tofacitinib + MTX or tofacitinib + placebo (PBO) from W24–48. In this post hoc analysis, clinical efficacy endpoints were ACR-N (minimum % change from baseline [BL; Δ] at W48 achieved by each pt in 3 efficacy measures), ΔDAS28-4(ESR), and DAS28-4(ESR) remission/LDA (scores ≤3.2) and moderate/high disease activity (scores >3.2). Functional efficacy endpoints were ΔHAQ-DI and HAQ-DI clinically relevant functional progression (CRFP) status at W48, defined as failure to achieve improvement in HAQ-DI ≥ minimum clinically important difference (MCID; ≥0.22 decrease from BL in HAQ-DI). Thus, CRFP was defined as <0.22 decrease, no change or increase from BL in HAQ-DI at W48. All efficacy endpoints were summarised descriptively. Cumulative probability plots of ACR-N and ΔHAQ-DI were produced. Median of mean CRP values from BL–W24 and >W24–48 were assessed by response subgroups.Results:266 pts receiving tofacitinib + MTX and 264 pts receiving tofacitinib + PBO in W24–48 were included. At W48: mean ACR-N was numerically greater with tofacitinib + MTX vs tofacitinib + PBO (60.8 vs 53.1); mean decrease in HAQ-DI was generally similar between groups (-0.71 vs -0.67); mean decrease in DAS28-4(ESR) was numerically greater with tofacitinib + MTX vs tofacitinib + PBO (-2.95 vs -2.68). The differences/similarities between groups in ACR-N and ΔHAQ-DI were also seen in cumulative probability plots (Figure 1). CRFP rates were numerically lower with tofacitinib + MTX (18.7%) vs tofacitinib + PBO (23.5%), and in pts with remission/LDA (tofacitinib + MTX, 12.1%; tofacitinib + PBO, 16.8%) vs moderate/high disease activity (tofacitinib + MTX, 26.2%; tofacitinib + PBO, 30.8%). Median of mean CRP over time was generally numerically lower in pts with CRFP vs non-CRFP and DAS28-4(ESR)-defined remission/LDA vs moderate/high disease activity; and in those receiving tofacitinib + PBO vs tofacitinib + MTX, irrespective of CRFP or DAS28-4(ESR) disease status (Table 1).Table 1.Median of mean CRPa up to W48 by response subgroupsTofacitinib 11 mg QD + MTXTofacitinib 11 mg QD + PBOMean CRP,amedian (IQR) [n]>BL–W24>W24–48>BL–W24>W24–48HAQ-DI CRFP2.84 (1.15–7.30)2.30 (0.82–4.75)1.45 (0.77–4.42)2.28 (0.53–7.28)[45][46][56][56]HAQ-DI non-CRFP2.81 (1.09–6.19)2.91 (1.19–5.84)2.26 (0.98–4.63)2.47 (1.13–5.53)[195][195][176][178]DAS28-4(ESR) remission/LDA2.48 (1.05–4.95)2.46 (1.07–4.76)1.70 (0.89–4.14)1.95 (0.81–3.82)[126][127][115][117]DAS28-4(ESR) moderate/high disease activity3.56 (1.17–7.13)3.58 (1.36–8.33)2.60 (0.87–5.16)2.68 (1.34–8.23)[107][107][115][115]aMean CRP was calculated as the average CRP value during each time period (>BL–W24 or >W24–48)CRP, C-reactive protein; DAS28-4(ESR), Disease Activity Score in 28 joints, erythrocyte sedimentation rate; HAQ-DI, Health Assessment Questionnaire-Disability Index; IQR, interquartile range; LDA, low disease activity; MTX, methotrexate; n, number of pts meeting assessment criteria; QD, once dailyConclusion:Although clinical/functional responses were generally similar between treatment groups, numerical improvements were seen for some efficacy endpoints with tofacitinib + MTX vs tofacitinib + PBO.

Abstract
OBJECTIVE Long non-coding RNAs (lncRNAs) have been identified to exert an oncogenic or anti-tumor function in malignant tumors. LncRNA SNHG15 is verified to be an oncogene in hepatocellular carcinoma, colorectal cancer, and prostate cancer. In this paper, we mainly investigate the potential influence of SNHG15 on the progression of nasopharyngeal carcinoma (NPC). PATIENTS AND METHODS SNHG15 levels in NPC tissues and cell lines were detected by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). Correlation between SNHG15 level and prognosis of NPC patients was evaluated by the Kaplan-Meier method. Regulatory effects of SNHG15 on proliferative, colony formation abilities, and apoptosis of SUNE1 and CNE1 cells were assessed through a series of functional experiments. Potential miRNAs binding SNHG15 and the downstream gene of the microRNA (miRNA) were predicted by bioinformatics method, which was confirmed by Dual-Luciferase reporter gene assay and Western blot. RESULTS SNHG15 was upregulated in NPC tissues and cells. High level of SNHG15 indicated worse survival in NPC patients. Knockdown of SNHG15 markedly suppressed proliferative ability and induced apoptosis in SUNE1 and CNE1 cells. It is verified that miR-141-3p was the direct target binding SNHG15, and KLF9 was the downstream gene of miR-141-3p. SNHG15 was demonstrated to be a ceRNA to upregulate KLF9 by competitively binding miR-141-3p. CONCLUSIONS SNHG15 is upregulated in NPC tissues, and this aggravates the progression of NPC by absorbing miR-141-3p to upregulate KLF9.

Abstract
In the present work, the vibrational normal modes (NM) of pyridine were revisited. Quantum Chemical calculations were performed to help understand the true nature of some ring related vibrational normal modes (RNM) and how they may be correlated with the electronic structure on the ring. The 27 vibrational normal modes were decomposed into the molecular internal coordinates, and the interest was focused on 7 of them, involving the in-plane ring motion. The electronic structure was analysed through frontier Molecular Orbitals (MO), maps of Molecular Electrostatic Potential surfaces (MEPs) and Natural Bond Orbital (NBO) analysis in a dynamic manner, wherein, each vibration was scanned. The present investigation is aimed to provide the Reader with a quantitative characterisation of the RNMs of pyridine.

Abstract
Objective: To evaluate the influence of the sleeve lengths and implant lengths on accuracy of static computer-assisted implant surgery (sCAIS). Methods: Twenty-eight models of bilateral mandibular single tooth loss were included. Fifty-five implants were placed under the guidance of sCAIS (Straumann Bone Level 4.1 mm×10 mm). According to the height of metal sleeve of static guide plate, 55 implants were divided into 11 groups (free hand group, 1 mm group, 2 mm group, 3 mm group, 4 mm group, 5 mm group, 6 mm group, 7 mm group, 8 mm group, 9 mm group, 10 mm group), with 5 implants in each group. Eight research models were included. Group with 5 mm sleeve guides were used to place implants of different length, (Straumann Bone Level width 4.1 mm, height was 8 mm, 10 mm and 14 mm), 5 implants in each group. Eighteen patients with mandibular single tooth loss were included in the Department of Oral Implantology, Tianjin Stomatological Hospital from October 2018 to June 2019. There were 10 males and 8 females, 18-46(33.7±7.9) years old. A total of 18 implants were implanted and divided into 3 groups (free hand group, 3 mm group and 5 mm group) with 6 implants in each group. Digital software was used to compare the implant positions before and after implantation. Non-parametric Kruskal-Wallis test or one-way ANOVA were used to analyze the results. Results: There was no significant difference in implant vertical deviation between different sleeve height groups (1-10 mm) and free hand group, but the neck deviation in free hand group[(1.04±0.13) mm] was significantly higher than that in different sleeve height groups (1-10 mm) (P<0.05). The tip deviations of free hand group, 1 mm group and 2 mm group [(1.32±0.43), (0.83±0.10) and (0.78±0.11) mm, respectively] was significantly higher than that of 10 mm group [(0.31±0.14) mm](P<0.05). The angle deviation of free hand group and 1 mm group (3.99°±0.85° and 2.59°±0.69°), respectively] was significantly higher than that of 10 mm group (0.61°±0.03°) (P<0.05). The tip deviations of implants in the 14 mm group [(0.83±0.22) mm] was significantly higher than that in the 8 mm and 10 mm groups [(0.44±0.07) and (0.49±0.06) mm, respectively]. Clinical studies showed that there was no significant difference in neck deviation, tip deviation and angle deviation between 3 mm group and 5 mm group (P>0.05), but deviations were significantly lower than those in free hand group (P<0.05). Conclusions: The length of the sleeves has significant influence on the accuracy of the surgical guide. There was no significant difference in accuracy of the implant guide with 3 mm or 5 mm metal sleeves. The vitro study has some limitations and needs further systematic research.

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
OBJECTIVE Reduced expression of suppressors of cytokine signaling 3 (SOCS3) is associated with a variety of tumors. The elevated miR-155 expression is associated with the onset of pancreatic cancer. Bioinformatics analysis revealed a targeted relation between miR-155 and the 3'-UTR of SOCS3. This study investigated whether miR-155 regulates SOCS3 expression and affects the biological effects of pancreatic cancer cells. PATIENTS AND METHODS QRT-PCR was used to detect the expression of miR-155 and SCOS3 mRNA in tumor tissues and paracancerous tissues of patients with pancreatic cancer. The dual luciferase reporter gene assay validated the target interaction between miR-155 and SOCS3. Pancreatic cancer cell line SW1990 cells were divided into miR-NC group and miR-155 inhibitor group followed by an analysis of the expressions of SOCS3, p-JAK2 and p-STAT3, cell apoptosis by flow cytometry, and cell proliferation by EdU staining. RESULTS Compared with adjacent tissues, miR-155 expression was increased in tumor tissues of patients with pancreatic cancer, and SOCS3 expression was decreased. There was a targeted regulatory relationship between miR-155 and SOCS3 mRNA. Compared with HPDE6-C7 cells, miR-155 expression in pancreatic cancer SW1990 and Capan-1 cells was increased, and SOCS3 expression was decreased. Transfection of miR-155 inhibitor significantly increased SOCS3 expression in pancreatic cancer SW1990 cells, decreased the expression of p-JAK2 and p-STAT3, increased cell apoptosis, and decreased cell proliferation. CONCLUSIONS Increased miR-155 expression and decreased SOCS3 expression are related to the pathogenesis of pancreatic cancer. miR-155 inhibits the proliferation and apoptosis of pancreatic cancer cells by inhibition of SOCS3 expression.

Abstract
OBJECTIVE microRNAs (miRNAs) were regarded as critical participators for human cancers progression including prostate cancer (PCa) and have the potential to be used as treatment targets for cancers. Herein, we validated a tumor-suppressive miRNA, miR-490-3p, which may suppress PCa progression. Histone deacetylase 2 (HDAC2) is a protein that aberrantly expressed in several cancers. However, the role of HDAC2 in the progression of PCa has not been fully elucidated. MATERIALS AND METHODS Expression of miR-490-3p and HDAC2 in PCa was investigated. The effects of miR-490-3p or HDAC2 expression on PCa cell behaviors were analyzed. Association between miR-490-3p and HDAC2 was analyzed by luciferase activity reporter assay and Western blot assay. RESULTS We demonstrated that miR-490-3p functioned as a tumor-suppressive role in PCa progression. We found miR-490-3p expression was decreased in PCa cell lines. Down-regulation of miR-490-3p promoted the growth, migration, invasion but inhibited apoptosis of PCa cells. HDAC2 was validated as a direct target of miR-490-3p and promoted the progression of PCa cells. Further studies showed that HDAC2 could reverse the effects of miR-490-3p on growth, migration, invasion and apoptosis of PCa cells. CONCLUSIONS Our data highlighted the key role of miR-490-3p in the progression of PCa. Thus, miR-490-3p may be a novel cancer-specific therapeutic.

Abstract
OBJECTIVE To compare the performance of methods based on text mining to screen suicidal behaviors according to chief complaint of the psychiatric inpatients. METHODS Electronic Medical Records of inpatients with mental disorders were collected. Text mining method was adopted to screen suicidal behaviors. The performances of different combinations of six algorithms and two term weighting factors were compared under various training set sizes, which were assessed by precision, recall, F1-value and accuracy. RESULTS A total of 3600 psychiatric inpatients (1800 with suicidal behaviors and 1800 without suicidal behaviors) were included in this study. In chief complaints of suicidal inpatients, "suicide", "notion" and "suspicion" were the commonest statements, appearing 1228, 705 and 638 times respectively. In contrast, "excitement", "instability" and "impulsion" appeared more frequently in chief complaints of patients without suicidal behaviors (599, 599, 534 times respectively). The performance of each algorithm was generally improved with the increasing training set sizes and tended to be stable when the number of training cases reached 1000, where most of them could achieve satisfactory accuracy values (>0.95). Results of testing set showed that SVM, Random Forest and AdaBoost weighted by TF had better generalization ability. The F1 values were 0.9889 for SVM, 0.9838 for random forest and 0.9828 for AdaBoost, respectively. CONCLUSION This study confirmed the feasibility of filtering suicidal inpatients with small amounts of representative terms. SVM, Random Forest and AdaBoost weighted by TF have better performance in this task. Our findings provided a practical way to automatically classify patients with or without suicidal behaviors before admission to hospital, which potentially led to considerable savings in time and human resources for identification of high-risk patients and suicide prevention.

Abstract
BACKGROUND The immune system is one of the most complex regulatory systems in the body and is essential for the maintenance of homeostasis. Despite recent breakthroughs in immunology, the regulation of the immune system and the etiology of autoimmune diseases such as lupus remain unclear. Systemic lupus erythematosus is a systemic autoimmune disease with abnormally and inconsistently expressed pro-inflammatory cytokines. Pyroptosis is a pro-inflammatory form of programmed cell death that is associated with systemic lupus erythematosus. The thymus and spleen are important immune organs involved in systemic lupus erythematosus. Therefore, this study investigated the difference in expression of pyroptosis-inducing pro-inflammatory cytokines between the spleen and thymus in lupus model mice and in control mice, to describe immune regulation at the organ level. OBJECTIVE To investigate differences in the expression of pyroptosis-inducing cytokines in the spleen and thymus and to explore immune regulatory networks at the organ level. METHODS Two groups of lupus mice and two groups of control mice were utilized for this study. Using the thymus and spleen of experimental animals, mRNA expression levels of five pyroptosis-inducing cytokines (interleukin 1β, interleukin 18, NLRP3, caspase-1 and TNF-α) were determined via quantitative polymerase chain reaction. In addition, tissue distribution of these cytokines was investigated via immunohistochemistry. RESULTS All five pyroptosis-inducing inflammatory cytokines showed higher expression in the spleen than in the thymus (p < 0.05). Moreover, the spleen/thymus expression ratios of all five pyroptosis-inducing cytokines were not statistically different between the four experimental groups. Expression of all five cytokines exhibited a stable ratio (spleen/thymus ratios). This distinctive stable spleen/thymus ratio was consistent in all four experimental groups. The stable spleen/thymus ratios of the five inflammatory cytokines were as follows: interleukin 1β (2.02 ± 0.9), interleukin 18 (2.07 ± 1.06), caspase-1 (1.93 ± 0.66), NLRP3 (3.14 ± 1.61) and TNF-α (3.16 ± 1.36). Immunohistochemical analysis showed the cytokines were mainly expressed in the red pulp region of the spleen and the medullary region of the thymus, where immune-activated cells aggregated. CONCLUSION The stable spleen/thymus expression ratios of pyroptosis-inducing cytokines indicated that immune organs exhibit strictly regulated functions to maintain immune homeostasis and adapt to the environment.

Abstract
Cucumber target leaf spot (TLS) disease caused by Corynespora cassiicola has become one of the most important fungal foliar diseases of cultivated cucumbers. However, the defense mechanisms of cucumber plants (Cucumis sativus) against C. cassiicola are still poorly understood. Here, proteins from resistant cucumber plants were analyzed using iTRAQ (isobaric tags for relative and absolute quantification) method. A total of 286 differentially expressed proteins were identified (p < 0.05, ratio > 1.2 or < 0.83) 6 and 24 h after pathogen inoculation in the resistant cultivar Jinyou 38 (the data are available via ProteomeXchange; identifier, PXD012903). Some of the early responses to C. cassiicola infection were revealed, and four factors related to the resistance of cucumber plants to TLS were discovered. First, the proteomic approach revealed modulation of signaling pathways in resistant cucumber plants in response to C. cassiicola infection. Second, the plant immune system recognizes the pathogen and initiates expression of immune response proteins, including those related to plant defense, stress response, signal transduction, cell metabolism, and redox regulation. Third, C. cassiicola activates common stress response pathways; in particular, mildew resistance locus O (MLO) proteins were found to play a crucial role in the TLS prevention. Fourth, rapid activation of the carbohydrate and secondary metabolic pathways, modification and reinforcement of cell walls, and adjustment of the apoplastic environment to the highly stressful conditions were crucial in the cucumber resistance to TLS. Overall, our data contribute to the understanding of interactions between plants and their pathogens and provide new insight into molecular processes involved in the resistance of cucumber plants to disease.

Abstract
Objective: To observe the effects of intravenous granisetron and acupuncture point injection at PC6(Neiguan) with 0.9% sodium chloride on postoperative nausea and vomiting (PONV) after gynecological laparoscopic surgery. Methods: Qualified cases were collected according to prospective randomized controlled clinical trial design. 94 cases patients undergoing gynecological laparoscopic surgery without postoperative intravenous analgesia were selected from February 2017 to November 2018 in Beijing Aerospace General Hospital and The Affiliated Hangzhou Hospital of Nanjing Medical University. The patients were randomly divided into three groups: bilateral PC6 sham injection of 0.9% sodium chloride+ intravenous granisetron(group A, n=31); bilateral acupuncture point injection at PC6 of 0.9% sodium chloride+ intravenous 0.9% sodium chloride(group B, n=33); bilateral acupuncture point injection at PC6 of 0.9% sodium chloride+ intravenous granisetron(group C, n=30). The indexes including age, body mass index(BMI), type of surgery, surgery time, anesthesia time, liquid intake and output volume, the time from the completion of the operation to the removal of the tracheal catheter, the time from the completion to follow the instruction, respiratory depression, restlessness, arrhythmias and other adverse reactions during anesthesia recovery were recorded. Evaluated the nausea and vomiting according to the visual analogue scales (nausea visual analog scale, NVAS) 12 hours after the operation. Not only the dose and the related frequency of antiemetic drugs for rescue, but also the time of the first anal exsufflation and the pain 24 hours after the operation were recorded. Detected the concentration of motilin (MTL), when the operation started/awake after extubation/12 hours after the operation Results: The incidence of nausea and vomiting 12 hours after the operation in group A, B and C was 35.5%, 33.3%, 10.0%. The difference was statistically significant (χ(2)=0.654, P<0.05). The motilin after 12 hours of operation in group A, B and C was (564±76),(559±84),(472±69) ng/L. The difference was statistically significant (F=14.033, P<0.05). The incidence of nausea and vomiting and the motilin after 12 hours of operation in group C were lower than group A and B. The time for the first anal exsufflation in group A, B and C was (19±8),(19±7),(14±8)h.The difference was statistically significant (F=4.523, P<0.05). The time for the first anal exsufflation in group C was earlier than group A and B. Conclusion: Either intravenous granisetron or acupuncture point injection at PC6 of 0.9% sodium chloride can effectively reduce the incidence of postoperative nausea and vomiting after gynecological laparoscopic surgery. Intravenous granisetron combined with acupuncture point injection at PC6 of 0.9% sodium chloride has better effect and promotes the first anal exsufflation time, which is conducive to the rapid postoperative recovery of patients.

Abstract
A highly sensitive α-Al2O3:C crystal was directly grown by the vertical gradient freezing (VGF) method using Al2O3 and graphite powder as the raw materials. The main thermoluminescence (TL) characteristics of α-Al2O3:C detectors grown by the VGF method and TLD-500K detectors were compared. The α-Al2O3:C grown by the VGF method shows good dosimetric properties, such as high TL sensitivity (152 times higher than that of the TLD-100 at heating rate of 1°C/s), an extremely low residual signal of 0.03%, a minimum measurable dose of 0.12 μGy and an excellent linear response within the dose range studied from 1 μGy to 10 Gy. The α-Al2O3:C detectors grown by the VGF method have a higher sensitivity and a better linear response compared to the TLD-500K detectors. Both kinds of α-Al2O3:C can be used in an unannealed form and to measure the very low dose in environmental monitoring and personnel dosimetry.

Abstract
OBJECTIVE The objective of this study was to observe the expression features of erythroblast macrophage protein (EMP) between the tissues of MRL/lpr mice, a mouse model of systemic lupus erythematosus (SLE), and control mice. METHODS We examined the serum ANA in both mice groups through indirect immunofluorescence (IIF). Expression features of EMP in bone marrow, liver, renal, spleen, brain, and lung tissues of the MRL/lpr mice and control mice groups were followed using quantitative real-time polymerase chain reaction (Q-PCR). Meanwhile, the expression of EMP was located through immunohistochemical (IHC) studies and the expressive cell identified through double immunofluorescent labeling. RESULTS IIF showed that lupus mice have strong positive fluorescence, but no significant fluorescence was observed in control mice. Q-PCR detection revealed that EMP was expressed in the marrow, liver, renal, spleen, lung, and brain tissues of lupus mice. The highest levels were observed in the bone marrow, but there was no statistical difference between these tissues. EMP mRNA expression in the liver (t = 2.747, p = 0.01) and bone marrow (t = 3.853, p = 0.008) of lupus mice was significantly higher than in the control mice. However, no differences in EMP mRNA expression were observed in the renal, spleen, lung, and brain tissues between the lupus and control mice (p > 0.05). In addition, the IHC results showed that EMP protein is ubiquitously expressed in all of the tissues of the lupus and control mice. The positive expression rate in the bone marrow and liver tissues of the lupus mice was higher than in the control mice, but without an obvious difference in the other tissues. The double IF staining method shows that EMP protein was expressed in macrophages in the tissues of the lupus mice and the control mice. CONCLUSIONS Our data showed that EMP is ubiquitously expressed in macrophages at all of the tissues of the lupus and control mice. However, the expression of EMP in bone marrow and liver tissues of lupus mice was higher than in the control mice, which indicates that EMP may be important in the development of SLE.

Abstract
Implantable neural probes that are mechanically compliant with brain tissue offer important opportunities for stable neural interfaces in both basic neuroscience and clinical applications. Here, we developed a Neurotassel consisting of an array of flexible and high-aspect ratio microelectrode filaments. A Neurotassel can spontaneously assemble into a thin and implantable fiber through elastocapillary interactions when withdrawn from a molten, tissue-dissolvable polymer. Chronically implanted Neurotassels elicited minimal neuronal cell loss in the brain and enabled stable activity recordings of the same population of neurons in mice learning to perform a task. Moreover, Neurotassels can be readily scaled up to 1024 microelectrode filaments, each with a neurite-scale cross-sectional footprint of 3 × 1.5 μm2, to form implantable fibers with a total diameter of ~100 μm. With their ultrasmall sizes, high flexibility, and scalability, Neurotassels offer a new approach for stable neural activity recording and neuroprosthetics.

Abstract
OBJECTIVE Less than half of eligible Chinese rural women have been screened for breast and cervical cancer. The objective of this study was to describe individual-level reasons for attending or not attending 'two cancers' screening using Andersen's Behavioral Model of Health Services Use. STUDY DESIGN Cross-sectional study. METHODS The study sample was from the Health Services Survey in 2013 in Jiangsu, China. A total of 6520 rural women aged 36-65 years answered the questions on 'two cancers' screening participation and were included in the final analysis, which consisted of univariate and multivariate logistic regression. RESULTS In the results of multivariate logistic regression, factors significantly associated with having 'two cancers' screening included educational level (odds ratio [OR] = 0.78, 95% confidence interval [CI] = 0.65-0.92), per capita household income (OR = 0.65, 95% CI = 0.58-0.73), availability of female medical faculty in township facilities (OR = 0.35, 95% CI = 0.28-0.42), quality of life (OR = 0.72, 95% CI = 0.58-0.90), being nulliparous (OR = 3.21, 95% CI = 1.96-5.26), and multiparous (OR = 1.91, 95% CI = 1.68-2.16). CONCLUSION To reduce inadequate screening service utilization of breast and cervical cancer in rural areas, efforts should be made not only to target the vulnerable rural women with lower income, lower educational level, and lower health conditions but also to further improve access to female primary-care providers. Strategies are also urgently needed to focus on nulliparous and multiparous women.

Abstract
The commensal gut microbial communities play an important role in the health and production efficiency of growing-finishing pigs. This study aimed to analyse the composition and diversity of the microbiota in the gastrointestinal tract sections (stomach, duodenum, jejunum, ileum, caecum, colon and rectum) of growing-finishing pigs. This analysis was assessed using 454 pyrosequencing targeting the V3–V6 region of the 16S rRNA gene. Samples were collected from 20, healthy pigs aged 24 weeks and weighing 115.9 ± 5.4 kg. The dominant bacterial phyla in the various gastrointestinal tract sections were Firmicutes, Bacteroidetes, Proteobacteria and Actinobacteria. At the genus level, Prevotella, unclassified Lachnospiraceae, Ruminococcus, unclassified Ruminococcaceae and Oscillospira were more abundant in the large intestine than in the stomach and the small intestine. Unclassified Peptostreptococcaceae and Corynebacterium were more abundant in the small intestine than in the stomach and the large intestine. Shuttleworthia, unclassified Veillonellaceae and Mitsuokella were more abundant in the stomach than in the small and large intestines. At the species level, M. el.s.d.enii and M. multacida were predominant in the stomach. In addition, P. stercorea, P. copri, C. butyricum, R. flavefaciens and R. bromii were significantly more abundant in the large intestine than in the stomach and the small intestine. B. pseudolongum and B. thermacidophilum were significantly more abundant in the small intestine than in the stomach and the large intestine. Principal coordinates analysis showed that the overall composition of the pig gastrointestinal microbiota could be clustered into three groups: stomach, small intestine (duodenum, jejunum and ileum) and large intestine (caecum, colon and rectum). Venn diagrams illustrated the distribution of shared and specific operational taxonomic units among the various gastrointestinal tract sections.
