Abstract
Echinococcosis poses a significant threat to public health. The Chinese government has implemented prevention and control measures to mitigate the impact of the disease. By analyzing data from the Chinese Center for Disease Control and Prevention and the State Council of the People's Republic of China, we found that implementation of these measures has reduced the infection rate by nearly 50% between 2004 to 2022 (from 0.3975 to 0.1944 per 100,000 person-years). Nonetheless, some regions still bear a significant disease burden, and lack of detailed information limites further evaluation of the effects on both alveolar and cystic echinococcosis. Our analysis supports the continuing implementation of these measures and suggests that enhanced wildlife management, case-based strategies, and surveillance systems will facilitate disease control.

Abstract
Objective: To compare the point-of-care assays for tear matrix metalloproteinase 9 (MMP-9) using domestic and InflammaDry kits, and to evaluate the feasibility of diagnosing dry eye with the domestic kit. Methods: It was a cross-sectional study. Thirty dry eye patients and 30 age-and sex-matched normal volunteers were continuously enrolled in this cross-sectional study from June 2022 to July 2022. Both domestic and InflammaDry kits were used to detect the tear MMP-9 levels. The positive rates were recorded for qualitative analysis, and the gray ratios of bands (the gray value of detection bands to that of control bands) were collected for quantitative analysis. The correlations of MMP-9 levels with age, ocular surface disease index, fluorescence tear break-up time, tear meniscus height, Schirmer's Ⅰ test score, corneal fluorescein staining score, and meibomian gland dropout were analyzed. The Mann-Whitney U test, paired Chi-square test, Kappa test, and Spearman's correlation coefficient were used for statistical analysis. Results: There were 14 males and 16 females (30 eyes) in the control group, and their age was (39.37±19.55) years. In the dry eye group, 11 males and 19 females (30 eyes), aged (46.87±17.85) years, had moderate to severe dry eye. The positive rates of MMP-9 in tear fluid were significantly different between dry eye patients (InflammaDry: 86.67%; domestic kit: 70.00%) and controls (InflammaDry: 16.67%, P<0.001; domestic kit: 6.67%, P<0.001). Although the sensitivity of the domestic kit was lower than that of the InflammaDry kit (70.0% vs. 86.7%, P=0.001), the specificity was higher (93.3% vs. 83.3%, P=0.001). In dry eye patients, the positive coincidence rate was 80.7% (21/26), the negative coincidence rate was 100% (4/4), and the total coincidence rate was 83.3% (25/30), with no significant difference between the two kits (McNemar test: χ2=3.20, P>0.05), and the results of both kits were consistent (Kappa=0.53, P=0.001). The Spearman's correlation coefficient showed the gray ratios using both kits were positively correlated with the corneal fluorescein staining score (InflammaDry: ρ=0.48, P<0.05; domestic kit: ρ=0.52, P=0.003). Conclusion: The performances of the domestic and InflammaDry kits are consistent in the point-of-care assay for tear MMP-9, and the domestic kit has lower sensitivity but higher specificity.

Abstract
Perfluoroalkyl substances (PFASs) constitute an environmentally persistent and widespread class of anthropogenic chemicals that have been used in industrial and commercial applications in the USA and around the world. Animal studies suggested its toxic impact on lung development, but the adverse effect of PFAS exposure on childhood pulmonary function has not been clearly determined. We investigated the potential cross-sectional association of environmental PFAS exposures with pulmonary function in 765 adolescents aged 12-19 years from the US National Health and Nutrition Examination Survey (NHANES) 2007-2012. Exposure to PFASs was estimated by measuring serum concentrations, and pulmonary function was assessed by spirometry. Linear regression and weighted quantile sum (WQS) regression were performed to estimate the associations of individual chemicals and chemical mixtures with pulmonary function. Median concentrations of PFOA, PFOS, PFNA, and PFHxS (detection frequencies > 90%) were 2.70, 6.40, 0.98, and 1.51 ng/mL, respectively. No associations were found between the four individual congeners and Σ4PFASs and the pulmonary function measures in total adolescents. Sensitive analyses were further conducted stratified by age (12-15 and 16-19 years) and sex (boys and girls). In adolescents aged 12-15 years, PFNA was negatively associated with FEV1:FVC (p-trend = 0.007) and FEF25-75% (p-trend = 0.03) among girls, while PFNA was positively associated with FEV1: FVC (p-trend = 0.018) among boys. No associations were found among adolescents aged 16-19 years, either boys or girls. The aforementioned associations were confirmed when further applying WQS models, and PFNA was identified to be the most heavily weighing chemical. Our results suggested that environmental exposure to PFNA may affect pulmonary function among adolescents aged 12-15 years. Given the cross-sectional analysis and less consistent results, further replications of the association in large prospective cohort studies are warranted.

Abstract
Objective: To explore whether hsa_circ_0000670 promotes the progression of gastric cancer by regulating the miR-515-5p/SIX1 molecular axis. Methods: The gastric cancer and adjacent normal tissues of 35 gastric cancer patients admitted to Rugao Hospital Affiliated to Nantong University from 2014 to 2015 were collected. The expression levels of circ_0000670, miR-515-5p and Sine oculis homeobox 1 (SIX1) in gastric cancer tissues and cells were detected by quantitative real-time polymerase chain reaction (qRT-PCR) and western blot. The correlations between circ_0000670 and miR-515-5p, miR-515-5p and SIX1, circ_0000670 and SIX1 were analyzed by the Pearson method. Patients were divided into low circ_0000670 expression group (17 cases) and high circ_0000670 expression group (18 cases) based on the median of circ_0000670 expression level, and Kaplan-Meier was used to analyze the 5-year survival of patients. Cell proliferation was assessed via clone formation assay. Cell cycle and apoptosis were detected by flow cytometry. Wound healing and Transwell assays were used to detect cell migration and invasion ability. The targeting relationship between miR-515-5p and circ_0000670 or SIX1 was confirmed by the dual luciferase reporter assay. Nude mice were injected into HGC-27 cells transfected with sh-NC or sh-circ_0000670, and the volume and weight of the transplanted tumor were measured, also, the levels of circ_0000670, miR-515-5p and SIX1 in the transplanted tumor tissue were detected. Results: The expression levels of circ_0000670 and SIX1 in gastric cancer tissues and cell lines were significantly increased (P<0.05), while the expression levels of miR-515-5p were significantly decreased (P<0.05). The survival rate of patients in the low circ_0000670 expression group (82.4%) was significantly higher than that in the high circ_0000670 expression group (28.7%, P=0.034). Circ_0000670 was negatively correlated with miR-515-5p (r=-0.846, P<0.001), and miR-515-5p was negatively correlated with SIX1 (r=-0.615, P<0.001), but circ_0000670 was positively correlated with SIX1 (r=0.814, P<0.001). Transfection of si-circ_0000670 or miR-515-5p mimic could significantly reduce the number of clone-forming cells, migration distance, migration and invasion cells (P<0.05), and increase the ratio of G(0)/G(1) phase cells, apoptosis rate and the protein level of E-cadherin (P<0.05), decreased the proportion of S-phase cells and the protein level of Vimentin (P<0.05). The dual luciferase report assay confirmed that circ_0000670 could target miR-515-5p, and miR-515-5p could bind to SIX1. Co-transfection of si-circ_0000670 and miR-515-5p inhibitor could significantly attenuate the effects of si-circ_0000670 on cell proliferation, migration, invasion, cell cycle and apoptosis (P<0.05). Co-transfection of miR-515-5p mimic and pcDNA-SIX1 could significantly reduce the effects of miR-515-5p mimic on cell proliferation, migration, invasion, cell cycle and apoptosis (P<0.05). Compared with the sh-NC group [volume=(596.20±125.46) mm(3) and weight=(538.00±114.39) g], the volume and weight of transplanted tumors in the sh-circ_0000670 group [volume=(299.20±47.58) mm 3 and weight=(289.80±48.73 g)] were significantly reduced (P<0.05), the expression levels of circ_0000670 and SIX1 were significantly reduced (P<0.05), and the expression level of miR-515-5p was significantly increased (P<0.05). Conclusion: Knockdown of circ_0000670 could inhibit cell proliferation, migration, invasion of gastric cancer cells, induce cell cycle arrest in G(0)/G(1) phase and promote cell apoptosis by regulating the miR-515-5p/SIX1 axis.

Abstract
OBJECTIVES Dietary Approaches to Stop Hypertension (DASH) pattern has been found to aid in the reduction of obesity, oxidative stress, and chronic inflammation, which are all strongly linked to the development of head and neck cancer (HNC). Nevertheless, no epidemiological studies have investigated the association between this dietary pattern and HNC risk. This study was conducted with the purpose of bridging this gap in knowledge. DESIGN A prospective cohort study involving 98,459 American adults aged 55 years and older. SETTING AND PARTICIPANTS Data were drawn from the Prostate, Lung, Colorectal, and Ovarian (PLCO) Trial. In the present study, participants with dependable energy intake data who furnished baseline and dietary history information were identified as the study population. METHODS Diet was assessed by food frequency questionnaires and the DASH score was calculated to assess each participant's adherence to DASH eating pattern. Cox proportional hazards models were used to calculate multivariable adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) for the occurrence of HNC. To visualize the variation in cancer risk for HNC and its subtypes across the entire spectrum of DASH scores, restricted cubic spline plots were utilized. Additionally, a series of predefined subgroup analyses were performed to identify potential effect modifiers, and several sensitivity analyses were conducted to assess the stability of the findings. RESULTS During a follow-up period of 871,879.6 person-years, 268 cases of HNC were identified, comprising 161 cases pertaining to oral cavity and pharynx cancers, as well as 96 cases of larynx cancer. In the fully adjusted model, adherence to the DASH diet was associated with a remarkable 57% reduction in the risk of HNC when comparing extreme quartiles (HR quartile 4 vs 1: 0.43; 95% CI: 0.28, 0.66; P for trend < 0.001). The restricted cubic spline plots demonstrated a linear dose-response relationship between the DASH score and the risk of HNC as well as its subtypes. Subgroup analysis revealed that the protective effect of the DASH diet against HNC was particularly pronounced in individuals with lower daily energy intake. The primary association remained robust in the sensitivity analysis. CONCLUSIONS In American middle-aged and older population, adherence to the DASH diet may help prevent HNC, particularly for individuals with lower daily energy intake.

Abstract
Objective: To examine the association of body mass index (BMI) and waist circumference (WC) with frailty among oldest-old adults in China. Methods: A total of 7 987 people aged 80 years and older (oldest-old) who participated in the Chinese Longitudinal Healthy Longevity Survey (CLHLS) in 2017-2018 were included. Information on demographic characteristics, behavior pattern, diet, activities of daily living, cognitive function, health status, disease condition were collected by questionnaire and physical examination. Generalized linear mixed model and restricted cubic splines (RCS) were used to analyze the association of BMI and WC with frailty. Results: The mean age of all participants was 91.7 years, and their mean BMI and WC were (21.3±3.5) kg/m2 and (82.9±10.5) cm, respectively. The proportion of male was 42.3% (3 377/7 987), and the proportion of people with frailty was 33.7% (2 664/7 987). After controlling confounding factors, compared with T2 (19.1-22.1 kg/m2) of BMI, the OR (95%CI) of the female T1 (<19.1 kg/m2) and T3 (≥22.2 kg/m2) group was 1.39 (1.17-1.65) and 1.27 (1.07-1.52), respectively. Compared with T2 (77-85 cm) of WC, the OR (95%CI) of female T1 (<77 cm) and T3 (≥86 cm) group was 1.20 (1.01-1.42) and 1.10 (0.93-1.31), respectively. The results of multiple linear regression model with restrictive cubic spline showed that there was a non-linear association of BMI and WC with frailty in female. Conclusion: There is a U-shaped association of BMI and WC with frailty in female participants.

Abstract
To understand the pathogenesis of acute lung injury (ALI), we focused on circEXOC5, a significantly up-regulated circular RNA in ALI. Using the in vivo cecal ligation and puncture (CLP)-induced ALI mouse model and in vitro LPS-challenged mouse pulmonary microvascular endothelial cell (MPVEC) model, we examined the impacts of knockdown circEXOC5 on lung injury, inflammation, and autophagy. The regulation between circEXOC5, polypyrimidine tract-binding protein 1 (PTBP1), S-phase kinase-associated protein 2 (Skp2), and Runt-related transcription factor 2 (Runx2) was investigated by combining RNA immunoprecipitation, qRT-PCR, mRNA stability, and ubiquitination assays. The significance of PTBP1 in circEXOC5-induced ALI phenotypes was examined both in vitro and in vivo. circEXOC5 was up-regulated and associated with increased inflammation and activated autophagy in cecal ligation and puncture-induced ALI lung tissues and LPS-challenged MPVECs. Through the interaction with PTBP1, circEXOC5 accelerated Skp2 mRNA decay, an E3 ubiquitin ligase for Runx2, and therefore increased Runx2 expression. Functionally, overexpressing PTBP1 reversed shcircEXOC5-inhibited ALI, inflammation, or autophagy. The signaling cascade circEXOC5/PTBP1/Skp2/Runx2, by essentially regulating inflammation and autophagy in MPVECs, aggravates sepsis-induced ALI.

Abstract
Objective: To explore the impact of composite clinical worsening (cCW) events and its components on the prognosis of patients with pulmonary arterial hypertension associated with congenital heart disease (CHD-PAH). Methods: This is a retrospective study. Patients who were diagnosed with CHD-PAH in Beijing Anzhen Hospital between January 2007 and July 2018, were included, and their baseline clinical data including demographic, clinical manifestations and New York Heart Association (NYHA) classification were collected retrospectively. All-cause deaths and clinical worsening events were recorded, which included syncope, PAH related hospitalization, NYHA classification deterioration and ≥ 2 PAH related clinical symptoms (dyspnea, hemoptysis, edema, chest pain, palpitations, cyanosis) appearance/progress. Three kinds of cCW events were defined: cCW1 (included PAH related hospitalization, NYHA classification deterioration), cCW2 (increased syncope on the basis of cCW1) and cCW3 (increased ≥ 2 PAH related clinical symptoms appearance/progress on the basis of cCW2). The Kaplan-Meier survival curve was used to analyze the long-term survival of the included patients. Univariate and multivariate Cox regression models were used to evaluate the impact of cCW events and their components on the risk of all-cause mortality. Results: A total of 525 patients with CHD-PAH were included in this study. The median age at diagnosis was 20.7 (11.2, 30.3) years. There were 43.8% children (<18 years), and 68.8% female patients. There were 431 patients (82.1%) with NYHA classification II. A total of 180 patients had PAH symptoms at diagnosis. The median follow-up time was 4.5 (2.6, 6.7) years. Forty-seven patients (9.0%) died during the follow-up period. Survival rates at 1, 5 and 10 years after diagnosis of PAH were 98.0%, 89.9% and 84.4%, respectively. Cox multivariate analysis showed that NYHA classification deterioration (HR=3.901, 95%CI 1.863-8.169, P<0.001), ≥2 PAH symptoms appearance/progress (HR=4.458, 95%CI 1.870-10.625, P<0.001), PAH-related hospitalization (HR=4.058, 95%CI 1.851-8.896, P<0.001) and syncope (HR=11.313, 95%CI 4.860-26.332, P<0.001) were independent predictors of increased risk of death. All 3 kinds of cCW events were significantly associated with the significantly increased risk of death, and cCW2 was highly predictive to increased risk of death (HR=15.476, 95%CI 4.346-37.576, P<0.001). Conclusions: The overall long-term prognosis of CHD-PAH patients in this study is relatively good. cCW events and its components (NYHA classification deterioration, ≥2 PAH symptoms occurrence/worsening, PAH-related hospitalization and syncope) have adverse influence on all-cause death in this patient cohort.

Abstract
Background In China, the average prevalence of asthma in children aged 0-14 years increased by approximately 50% every 10 years. Hence, a specific decision support system that fits China's situation is needed for childhood asthma. This prospective, multicenter, observational study aims to assess the accuracy of the Childhood Asthma Model for Clinical Decision Support (CAMCDS) in clinical practice in four hospitals in Shanghai in China. Methods The study will be conducted in two phases. Phase I of the study aims to evaluate the accuracy of the CAMCDS for diagnosis, while phase II of the study aims to examine the treatment predicting accuracy of the CAMCDS model. In total, 817 children diagnosed with stable asthma and 545 suspected asthma will be enrolled. The accuracy of the CAMCDS model will be calculated using the receiver operating characteristic (ROC) curve compared with the results of pediatrician's diagnosis. Besides, the treatment patterns from CAMCDS and real-world environment for Chinese children with stable asthma will be assessed, and the factors that affect the CAMCDS implementation in routine clinical practice will be explored. Conclusions This will be the first study to examine the diagnostic accuracy and treatment predicting accuracy of a clinical decision support system in children with asthma in China. We hope that the CAMCDS will be help pediatricians in basic-level hospitals to improve the diagnosis and treatment strategy of asthma.

Abstract
The feasibility of submandibular gland (SMG) preservation during neck dissection has been described. The aim of this study was to analyse the functional outcomes in patients undergoing SMG preservation during neck dissection for cT1-2N0 oral squamous cell carcinoma. Consecutive patients were divided into two groups based on the management of the SMG, and underwent a saliva flow test before surgery, 7 days after surgery, and at 3, 6, 9, and 12 months after surgery. All enrolled patients completed the fourth version of the University of Washington Quality of Life (UWQOL) questionnaire at 12 months after surgery. In patients who underwent SMG preservation during neck dissection, the flow rate at 7 days after surgery was significantly lower than that preoperative; however, it gradually returned to baseline at 9 months after surgery. The saliva flow rate at 9 months after surgery was similar to that at 12 months after surgery. Further, patients with SMG preservation had higher scores for the activity, swallowing, chewing, and saliva domains than patients without SMG preservation. The results of the study suggest that saliva secretion ability can be preserved following SMG-sparing neck dissection, and that SMG preservation improves postoperative quality of life.

Abstract
Introduction Presence of heart failure is associated with a poor prognosis in patients with COVID-19. The aim of the present study was to examine whether first-phase ejection fraction (EF1), the ejection fraction measured in early systole up to the time of peak aortic velocity, a sensitive measure of pre-clinical heart failure, is associated with survival in patients hospitalised with COVID-19. Methods A retrospective outcome study was performed in patients hospitalised with COVID-19 who underwent echocardiography (n=380) at the West Branch of the Union Hospital, Wuhan, China and in patients admitted to King's Health Partners in South London UK. Association of EF1 with survival was performed using Cox proportional hazards regression. EF1 was compared in patients with COVID-19 and in historical controls with similar co-morbidities (n=266) who had undergone echocardiography before the COVID-19 pandemic. Results In patients with COVID-19, EF1 was a strong predictor of survival in each patient group (Wuhan and London). In the combined group, EF1 was a stronger predictor of survival than other clinical, laboratory and echocardiographic characteristics including age, co-morbidities and biochemical markers (figure 1). A cut-off value of 25% for EF1 gave a hazard ratio of 5.23 (95% CI: 2.85–9.60, p<0.001) unadjusted and 4.83 (95% CI: 2.35–9.95, p<0.001) when adjusted for demographics, co-morbidities, hs-cTnI and CRP (figure 2). EF1 was similar in patients with and without COVID-19 (23.2±7.3 vs 22.0±7.6%, p=0.092, adjusted for prevalence of risk factors and co-morbidities). Conclusion Impaired first-phase ejection fraction is strongly associated with mortality in COVID-19 and probably reflects pre-existing, pre-clinical heart failure.

Abstract
INTRODUCTION A very limited option of inhaled corticosteroids (ICSs) is approved for pediatric use in China because in children the use of ICSs for long periods is associated with dose-dependent growth reduction. Due to the lack of consensus on which is the best ICS-based treatment option to manage mild persistent asthma in children, the present study was performed to evaluate the efficacy and safety of budesonide (BUD)-based therapy vis-à-vis mometasone-based therapy in children with mild persistent asthma. METHODS A single-center, retrospective study was conducted in asthmatic children aged between 6 and 11 years. BUD and mometasone furoate (MF) were administered as per the approved dosing regimen using pressurized metered-dose inhalers via oral inhalation route for a period of 12 weeks. The study outcome was assessed in terms of the forced expiratory volume in 1 s (FEV1), symptom scores, and nonoccurrence of side effects. RESULTS Among the 77 asthmatic children, 71 completed the study treatment and were used in carrying out the analysis. The improvement of spirometric parameters like FEV1, Tiffeneau-Pinelli index (FEV1/forced vital capacity [FVC]), and peak expiratory flow (PEF) values observed in the MF cohort was significantly greater than those of the BUD cohort (p < 0.05 for all). An increase of approximately 12%/child was observed for FEV1/FVC ratios for the BUD cohort and MF cohorts. After the 12-week study, the PEFm and PEFe values increased to about 50 L/min/child for the BUD cohort and about 98 L/min/child for the MF cohort. During the study, no asthma exacerbation event was observed in the MF cohort, whereas 1 child in the BUD cohort had asthma exacerbation in week 4. The use of rescue medication during the study was required for 16.2 and 6% of children, respectively, for BUD and MF cohorts. Owing to low dosing frequency, MF could provide a better treatment approach than BUD due to improved patient compliance. CONCLUSIONS Although both drugs showed improvement in the quality of life of asthmatic children with manageable treatment-emergent adverse effects, the improvement was augmented in MF-treated children. LEVEL OF EVIDENCE The level of evidence was III. Technical Efficacy Stage: The technical efficacy stage was 4.

Abstract
BACKGROUND Asthma is a chronic respiratory disease worldwide. This study aimed to explore the functions of the long noncoding RNA LINC-PINT (LINC-PINT) in asthma and to determine its underlying molecular mechanisms. METHODS Rat asthma model was established with ovalbumin sensitization and challenge. The serum level of IgE, airway hyperresponsiveness (AHR), airway inflammation, and pathological changes of lung were evaluated. Airway smooth muscle cells (ASMCs) were stimulated with platelet-derived growth factor-BB (PDGF-BB) to mimic the asthma-like condition at cellular level. QRT-PCR was performed to detect the expression of LINC-PINT, microRNA-26a-5p (miR-26a-5p), and PTEN. MTT and transwell assays were performed to measure the viability and migration of ASMCs. The protein expression of airway remodelling marker MMP-1 and MMP-9 was measured by western blot. The interactions among LINC-PINT, miR-26a-5p, and PTEN were determined by dual-luciferase reporter assay. RESULTS The expression of LINC-PINT and PTEN was decreased, while miR-26a-5p expression was increased in PDGF-BB-stimulated ASMCs. In vivo, overexpression of LINC-PINT decreased the serum level of IgE, AHR, airway inflammation, and pathological changes of lung in asthma rat model. In vitro, up-regulation of LINC-PINT decreased the viability, migration, and MMP-1 and MMP-9 protein expression in PDGF-BB-stimulated ASMCs. Dual-luciferase reporter assay determined that LINC-PINT targeted miR-26a-5p, and miR-26a-5p targeted PTEN in ASMCs. Feedback approaches confirmed that miR-26a-5p up-regulation or PTEN down-regulation reversed the suppressive effect of LINC-PINT overexpression on the abnormal growth of ASMCs. CONCLUSIONS LINC-PINT overexpression retarded the abnormal growth of ASMCs by regulating the miR-26a-5p/PTEN axis, offering a potential therapeutic target for asthma.

Abstract
Objective: To investigate the effect of plasma uric acid level on the incident risk of type 2 diabetes mellitus (T2DM) among the oldest old (those aged ≥80 years). Methods: Participants were recruited from the Healthy Aging and Biomarkers Cohort Study (HABCS), which conducted a baseline survey in 2008-2009 and follow-up of 3 times in 2011-2012, 2014, and 2017-2018, respectively. A total of 2 213 oldest old were enrolled in this study. The general demographic, socioeconomic, lifestyle and disease data of the oldest old were collected, and physical measurements were made for the oldest old. Fasting venous blood was collected for uric acid and blood glucose detection. Information on the incident and death of T2DM were collected through the follow-up. Cox proportional hazard regression model was used to explore the association of hyperuricemia and plasma uric acid level with the incidence of T2DM. Restricted cubic spline (RCS) function was used to explore the dose-response relationship of plasma uric acid levels with the risk of T2DM. Results: The age of participants was (93.2±7.6) years old, and 66.7% of the participants (1 475) were female. The plasma uric acid level at baseline was (289.1±88.0)μmol/L, and the prevalence of hyperuricemia was 13.3% (294 cases). During 9 years of cumulative follow-up of 7 471 person-years (average of 3.38 years for each), 122 new cases of T2DM occurred and the incidence density was 1 632.98/105 person year. Cox proportional hazards regression analysis showed that per 10μmol/L increase in plasma uric acid level, the risk of T2DM increased by 1.1% [HR (95%CI): 1.011 (1.004, 1.017)]. Compared with the participants with the lowest quintile of plasma uric acid (Q1), the risk of diabetes increased by 20.7 % among the oldest old with uric acid in the highest quintile (Q5) [HR (95%CI):1.207 (1.029, 1.416)]. The risk of T2DM was 19.2% higher in the hyperuricemia group than that in the oldest old with normal plasma uric acid [HR (95%CI): 1.192 (1.033, 1.377)]. RCS function showed that the risk of T2DM increased with the increase in plasma uric acid levels in a nonlinear dose-response relationship (P=0.016). Conclusion: The incident risk of T2DM increases with the elevates of plasma uric acid levels in the oldest old.

Abstract
BACKGROUND Late recovery in patients following prolonged coma from carbon monoxide poisoning have been reported, but the probability is unclear. The purpose of this research was to assess the prognosis of patients in prolonged coma after severe carbon monoxide poisoning and related clinical and imaging features. METHODS There were 13 patients who had been in a state of coma for >7 days after acute carbon monoxide poisoning in the retrospective observational study, and demographic data, clinical data, laboratory data, complications, and image data were collected. Outcome was assessed by means of the Glasgow outcome scale after 1 year. The relationship between complications and imaging manifestations and prognosis was also analyzed. RESULTS One year after severe carbon monoxide poisoning, two patients (15.4%) had died (GOS 1), nine (69.2%) were in a persistent vegetative state (GOS 2), one (7.7%) was moderately disabled (GOS 4), and one (7.7%) achieved a good recovery (GOS 5) with minimal disability. CONCLUSIONS Most patients with prolonged coma after severe carbon monoxide poisoning had a poor prognosis, although the younger patients had a better prognosis. Respiratory failure, hypotension and renal failure during the course of the disease were associated with a poor prognosis. The prognosis of patients with injuries in two sites in early CT was poor. Multiple lesions (≥3) and extensive white matter damage (Fazekas grade (PVH or DWMH) = 3) on MRI of chronic phase were also associated with a poor prognosis.

Abstract
Epidemiological studies have reported association of urinary 3-phenoxybenzoic acid (3-PBA), a major metabolite of pyrethroid insecticides (PYRs), with respiratory disease. However, knowledge regarding its effect on pulmonary function in susceptible children is limited. This study aimed to assess the associations between environmental 3-PBA concentrations and pulmonary function in children aged 6-17 years. Using data on 1174 children aged 6-17 years from the U.S. National Health and Nutrition Examination Survey (NHANES) 2007-2012, the exposure to PYRs was assessed by measuring urinary 3-PBA concentrations and pulmonary function was assessed by spirometry. Multivariable linear regression and generalized linear models (GLMs) were used to examine the associations between 3-PBA concentrations and pulmonary function in children, controlling for confounders. We found that 3-PBA concentrations were inversely associated with forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC), and peak expiratory flow (PEF) in the pediatric population (p-trends < 0.05). When stratified by age (6-10 and 11-17 years) and gender (boys and girls), the adverse effects of PYR exposures on pulmonary function were more pronounced among boys aged 11-17 years. Among this age group, 3-PBA concentrations were negatively associated with FEV1, FVC, forced expiratory flow between 25% and 75% of FVC (FEF25-75%), and PEF. However, among children aged 6-10 years, no associations were found between 3-PBA concentrations and any of the pulmonary function measures, in either boys or girls. Our findings suggest that environmental PYR exposures may adversely affect children's pulmonary function, with the strongest associations among 11-17 years old boys.

Abstract
Objective: To investigate the association between blood lead concentrations and cognition impairment among Chinese older adults aged 65 or over. Method: Data was collected in 9 longevity areas from Heathy Aging and Biomarkers Cohort Study between 2017 and 2018. This study included 1 684 elderly aged 65 years and older. Information about demographic characteristics, socioeconomic factors, health status and cognitive function score of respondents were collected by questionnaire survey and physical examination. Venous blood of the subjects was collected to detect the blood lead concentration. Subjects were stratified into four groups (Q1-Q4) by quartile of blood lead concentration. Multivariate logistic regression model was used to analyze the association between blood lead concentration and cognitive impairment. The linear or non-linear association between blood lead concentration and cognitive impairment were described by restrictive cubic splines (RCS). Results: Among the 1 684 respondents, 843 (50.1%) were female and 191 (11.3%) suffered from cognition impairment. After adjusting for confounding factors, the OR value and 95%CI of cognition impairment was 1.05 (1.01-1.10) for every 10 μg/L increase in blood lead concentration in elderly; Compared with the elderly in Q1, the elderly with higher blood lead concentration had an increased risk of cognitive impairment. The OR value and 95%CI of Q2, Q3 and Q4 groups were 1.19 (0.69-2.05), 1.45 (0.84-2.51) and 1.92 (1.13-3.27), respectively. Conclusion: Higher blood lead concentration is associated with cognitive impairment among the elderly aged 65 years and older in 9 longevity areas in China.

Abstract
Objective: To investigate the association of blood oxidative stress level with hypertriglyceridemia in the elderly aged 65 years and older in China. Methods: A total of 2 393 participants aged 65 years and older were recruited in 9 longevity areas from Heathy Aging and Biomarkers Cohort Study, during 2017 to 2018. Information on demographics characteristic, life style and health status were collected by questionnaire and physical examination, and venous blood was collected to detect the levels of blood oxidative stress and hypertriglyceridemia. The linear or non-linear association between oxidative stress and hypertriglyceridemia was described by restrictive cubic splines (RCS) fitting multiple linear regression model. The generalized linear mixed effect model was conducted to assess the association between oxidative stress and hypertriglyceridemia. Results: A total of 2 393 participants, mean age was 84.6 years, the youngest was 65 and the oldest was 112, the male was 47.9%(1 145/2 393), the triglyceride level was (1.4±0.8) mmol/L. The hypertriglyceridemia detection rate was 9.99%(239/2 393). The results of multiple linear regression model with restrictive cubic spline fitting showed that MDA level was linear association with triglyceride level; SOD level was nonlinear association with triglyceride level. MDA level had significantly association with hypertriglyceridemia, and the corresponding OR value was 1.063 (95%CI: 1.046,1.081) with 1 nmol/ml increment of blood MDA; SOD level had significantly association with hypertriglyceridemia, and the corresponding OR value was 0.986(95%CI: 0.983,0.989) with 1 U/ml increment of blood SOD. Conclusion: Among the elderly aged 65 and older in 9 longevity areas in China, MDA and SOD levels were associated with the risk of hypertriglyceridemia.

Abstract
Background: Mycoplasma pneumoniae (MP) not only was a common pathogen of respiratory tract infections, but also could trigger the exacerbation of asthmatic symptoms in children with or without asthma. Objective: This study aimed to identify possible risk factors associated with wheezing among children diagnosed with MP infection. Methods: A retrospective analysis of medical records of children aged 28 days to 18 years old who visited the Shanghai Children's Hospital between January 2019 and January 2020 was carried out, and all children were then classified into three groups: two wheezing groups (with or without MP infection) and a non-wheezing group with MP infection. Information including patient's demographics, clinical features, laboratory data, and radiography findings was extracted from the electronic medical record system. Chest radiographs were reviewed independently by two board-certified, blinded pediatric radiologists. Results: A total of 1,512 patients were included in our study, and 21.9% of them belonged to the wheezing group without MP infection. Among 1,181 patients with MP infection, 295 people (25.0%) suffered from wheezing, and males accounted for 61%. Through the multivariable logistic regression analyses, we found that six variables were positively associated with wheezing attacks in children with MP infection: male gender (likelihood ratio [LR] = 2.124, 95% confidence interval [CI]: 1.478-3.053), history of allergy (LR= 3.301, 95% CI: 2.206-4.941), history of wheezing (LR = 7.808, 95% CI: 5.276-11.557), autumn in reference to summer (LR = 2.414, 95% CI: 1.500-3.885), non-end-point infiltration in reference to consolidation or pleural effusion (LR = 1.982, 95% CI: 1.348-2.914), and infiltration scope (LR = 1.773, 95% CI: 1.293-2.432). However, the model showed that the probability of wheezing after MP infection decreased as age increased (LR = 0.257, 95% CI: 0.196-0.337). Moreover, the area under the curve (AUC) of the regression model was as high as 0.901 (0.847-0.955). Conclusion: The model integrated with factors including gender, age, season, radiological patterns, infiltration scope, and history of allergy performed well in predicting wheezing attack after MP infection in children.

Abstract
Abstract
Background
Cardiac Resynchronization Therapy (CRT) is an important therapeutic treatment for chronic heart failure. However, even in carefully selected cases up to 40% of patient fail to respond. First-phase ejection fraction (EF1), the ejection fraction up to the time of maximal ventricular contraction, is a novel and more sensitive echocardiographic measure of early systolic function.
Purpose
We examined the value of EF1, to predict response to CRT and clinical outcomes after CRT.
Methods
We analysed echocardiograms from 197 patients who underwent CRT between 2009 and 2018 and were followed to determine clinical outcomes.
Results
Volumetric response rate (reduction in end-systolic volume ≥15%) was 92.3% vs. 12.1%, for those with EF1 in the highest vs. lowest tertiles (p<0.001). A cut-off value of 11.9% for EF1 had >85% sensitivity and specificity for prediction of response to CRT; on multivariate logistic regression analysis incorporating previously defined predictors, EF1 was the strongest predictor of response (OR: 1.563, 95% CI: 1.371–1.782, p<0.001) (table 1). EF1 was also the strongest predictor of a clinical composite score (OR: 1.115, 95% CI: 1.044–1.191, p=0.001). Improvement in EF1 at 6 months after CRT implantation (6.5±5.8% vs 1.8±4.3% in responders vs. non-responders, p<0.001) was the best predictor of heart failure re-hospitalization and death after median follow-up of 29.2 months (HR: 0.819, 95% CI:0.765–0.876, p<0.001).
Conclusion
EF1 is a promising marker to identify patients likely to respond to CRT and most likely provides a measure of myocardial viability that determines response.

Abstract
Egg-type ducks and meat-type ducks are predominantly commercial or indigenous and have been subjected to artificial directional selection. These two duck types differ substantially in body shape, production performance and reproductivity. However, the genetic changes associated with phenotypic differences remain unclear. Here, we compared the two duck types at the genomic and transcriptomic levels. We identified a large number of SNPs and genes in genomic divergent regions in terms of FST and θπ values. The corresponding genes were mainly enriched in embryonic development function and metabolic pathway. RNA-seq analysis also revealed differential gene expression in the liver and gonads. The differentially expressed genes were functionally associated with signal transmission and substance metabolism respectively. Furthermore, we found that seven genes were related to differentiation between the two types by both g genome and transcriptome analysis and were plausible candidate genes. These genes were annotated to GO categories of cell development and disease immunity. These findings will enable a better understanding of the artificial selection history of meat and egg ducks and provide a valuable resource for future research on the breeding of these two lineages.

Abstract
RATIONALE Although bronchiectasis is conventionally considered a chronic pulmonary disease of adulthood, knowledge of pediatric bronchiectasis not related to cystic fibrosis started to emerge. Limited information in this field is available and the management is based on expert opinion. PATIENT CONCERNS An 8-year-old girl admitted for 7 days history of wet cough, purulent fetid sputum, shortness of breath and low-grade fever. The wet cough has presented for the past 4 years, during which she had frequent hospitalization for recurrent lower respiratory tract infections. DIAGNOSIS Chest high-resolution computerized tomography revealed diffuse bronchial dilations accompanied by inflammation in the bilateral lung fields. Microbiologic investigation for bronchoalveolar lavage fluid was positive for Pseudomonas aeruginosa. INTERVENTIONS With a working diagnosis of bronchiectasis with secondary pulmonary infection, sensitive cefoperazone-sulbactam was administrated for 14 days with gradual improvement of clinical symptoms. Bronchoscopy washing substantially soothed the symptoms, reducing the cough and sputum volumes. OUTCOMES The child was discharged after 14 days, and treated on long-term prophylactic antibiotic use (amoxicillin-clavulanic acid, 20 mg/kg/d, ≥ 4 weeks). LESSONS Although bronchiectasisis are condition in childhood, the diagnosis is suspected in children with persistent wet or productive cough, and should be confirmed by a chest high-resolution computerized tomography scan. Antibiotics and airway clearance techniques represent the milestones of bronchiectasis management although there are only a few guidelines in children.

Abstract
OBJECTIVE The aim of this study was to explore the effect of long non-coding ribonucleic acid (lncRNA) KCNQ1 overlapping transcript 1 (KCNQ1OT1) on fracture healing and its possible mechanism. PATIENTS AND METHODS Abnormal lncRNAs were compared between patients with delayed fracture healing and those with normal fracture healing using gene expression profiling method. LncRNA expression in patients was verified by quantitative Reverse Transcription-Polymerase Chain Reaction (qRT-PCR). Subsequently, the model of tibial fracture was successfully established in rabbits. The effect of lncRNA KCNQ1OT1 expression on tibial fracture healing in rabbits was explored. Meanwhile, the effects of lncRNA KCNQ1OT1 on cell proliferation and apoptosis were investigated by knockdown and overexpression experiments with HC-a as a cell model. Furthermore, Western blotting was used to explore the expressions of proteins in signaling pathway affected by lncRNA KCNQ1OT1. RESULTS Gene expression profiling and qRT-PCR revealed that lncRNA KCNQ1OT1 was significantly down-regulated in bone tissues of patients with delayed fracture healing. Compared with the control group, knocking down lncRNA KCNQ1OT1 remarkably reduced the serum levels of alkaline phosphatase (ALP) and osteoprotegerin (OPG) in rabbits, and markedly decreased bone trabecular growth index (p<0.05). In HC-a cells, overexpression of lncRNA KCNQ1OT1 activated the Wnt/β-catenin signaling pathway, which could be suppressed by knocking down lncRNA KCNQ1OT1. Cell Counting Kit-8 (CCK-8) assay and 5(6)-carboxyfluorescein diacetate, succinimidyl ester (CFSE) results manifested that lncRNA KCNQ1OT1 remarkably promoted the proliferation and inhibited apoptosis of HC-a cells by activating the Wnt/β-catenin signaling pathway. CONCLUSIONS LncRNA KCNQ1OT1 plays a vital role in delayed fracture healing. Moreover, it can induce cell proliferation and inhibit cell apoptosis by activating the Wnt/β-catenin signaling pathway. Therefore, KCNQ1OT1 may be used as a biomarker to predict the occurrence of delayed fracture healing.

Abstract
Objective: To explore the risk factors for death in patients with pulmonary arterial hypertension related to congenital heart disease (PAH-CHD) and the clinical characteristics of different subtypes in patients with PAH-CHD. Methods: It was a retrospective study. A total of 507 PAH-CHD patients, who were hospitalized in the Department of Pediatric Cardiology of Beijing Anzhen Hospital between September 2005 and May 2019, were included. Patients were divided into 4 subgroups: (1) Eisenmenger syndrome(ES) group. (2) PAH associated with prevalent systemic-to-pulmonary shunts(SP) group. (3) PAH associated with small defects(SD) group. (4) PAH after defect correction(CD) group. According to the complexity of cardiac malformation, patients were divided into simple-medium complex malformation group and complex malformation group. According to the location of shunts, patients were divided into pre-tricuspid group, post-tricuspid group, and mixed group or complex deformity group. Baseline clinical data of patients were collected from the electronic medical record system. Demographic data (age, gender, etc.), percutaneous oxygen saturation(SPO(2)), New York Heart Association(NYHA) cardiac function classification, 6 minutes walking distance(6MWD), and B type natriuretic peptide(BNP), systolic pulmonary arterial pressure(sPAP) estimated by echocardiography and mean pulmonary artery pressure (mPAP), mean right atrial pressure(mRAP), cardiac index(CI), and calculated pulmonary vascular resistance (PVR) estimated by right heart catheterization were compared among various groups. The results of regular follow-up of all enrolled patients were collected, including the status of monotherapy or combination of PAH-targeted drugs during the follow-up period, cardiac-related adverse events(hemopysis, syncope, edema, arrhythmia, etc.) and primary endpoint event(all-cause death) were obtained and analyzed. Risk factors for all-cause death were analyzed using univariate and multivariate Cox regression analysis model. Results: The median age at diagnosis was 23.1(13.9,32.1) years, 345 cases(68.0%) were female. Two hunderds and thirty-five cases(46.4%) were diagnosed with ES; 193 cases(38.1%) were diagnosed with CD, 47 cases (9.3%) were diagnosed with SD. Among them, 32 cases(6.3%) were in the SP group. All 507 patients underwent echocardiography examination, there were significant differences in sPAP among different clinical subgroups(P<0.001). A total of 289 patients(57.0%) received right heart catheterization examination, the results showed that the ES group had the highest mPAP and PVR and the lowest mRAP(all P<0.001), the CD group had the highest mRAP and CI(both P<0.001). The 6MWD in the ES group was significantly shorter than that in the SP, SD, and CD groups(all P<0.001). The proportion of patients with NYHA class Ⅲ/Ⅳ was higher in SD group than in SP group(P<0.001), which was similar between SD, ES and CD groups (P values were 0.077 and 0.072, respectively). At admission, the proportion of patients with NYHA class Ⅰ/Ⅱwas the highest in SP group(96.9% (31/32) ), followed by CD group (85.5%(165/193)) and the ES group(85.1%(200/235)), and the SD group(75.0%(35/47)). The BNP level at admission was also higher in SD group than in SP, ES and CD groups(P<0.001). Of the 507 patients, 379(74.8%) patients received PAH-targeted drug therapy at the last follow-up, and the treatment plan was mainly monotherapy(75.7%(287/379)). The median follow-up time was 3.6(2.0, 5.6) years and 37(7.3%) patients died, including 13 in the CD group, 17 in the ES group, and 7 in the SD group. No deaths occurred in the SP group. Right heart failure was the most common cause of death(11(29.7%)), followed by severe hemoptysis dyspnea(7(18.9%)), sudden cardiac death(6(16.2%)), and pulmonary hypertensive crisis(4(10.8%)). Kaplan-Meier curve showed that survival rates of end-point-free events at 1, 3, 5 and 10 years after diagnosis of PAH were 98.0%, 95.4%, 89.9%, and 84.4%, respectively; there were statistically significant differences in survival among the subgroups(P=0.026); there was no significant difference in the survival rate between the ES group and the CD group(P=0.918), and both were higher than the SD group(P values were 0.011 and 0.013, respectively). Univariate Cox regression analysis showed that NYHA class Ⅲ/Ⅳ and BNP>100 ng/L at admission were the risk factors for all-cause death in patients with PAH-CHD(HR=6.452, 95%CI 3.378-12.346, P<0.001, and HR=2.481, 95%CI 1.225-5.025, P=0.012). Multivariate Cox regression analysis showed that NYHA class Ⅲ/Ⅳ was an independent risk factor for all-cause death in patients with PAH-CHD(HR=4.998, 95%CI 1.246-20.055, P=0.023). Conclusions: PAH-CHD patients with different clinical subtypes have different clinical symptoms, cardiac functional class, hemodynamic characteristics, and mid to long-term survival rates. SP patients have the best prognosis, outcome of ES and CD patients is similar, and SD patients have the worst prognosis. NYHA class Ⅲ/Ⅳ is an independent risk factor for all-cause death in patients with PAH-CHD.

Abstract
Previous studies suggested an association between female fertility and body size, but most of these studies were from Western countries and focused mainly on obesity. This study investigated the association between preconception body mass index (BMI) and time to pregnancy (TTP) in women planning to conceive from Shanghai, China. A total of 1,182 women aged 24-46 years were recruited from the Shanghai Birth Cohort between 2013 and 2015 and were followed up for 12 months. Preconception BMI was categorized as underweight, normal weight, and overweight/obesity according to the Chinese classification of BMI. Fecundability (FOR) and infertility (IOR) odds ratios were estimated using Cox (n = 1,092) and Logistic (n = 820) regression models, respectively. We found no differences in fecundability between underweight and overweight/obese women and normal-weight women. Furthermore, underweight and overweight/obese women did not have a higher risk of infertility compared with normal-weight women. Our findings suggest that non-optimal preconception BMI does not appear to influence female fecundability and infertility in Chinese women. These results should be interpreted with caution as they may be applicable only to women with demographic and anthropometric characteristics similar to our study population. Our findings need to be confirmed in other populations.

Abstract
Foreign body (FB) aspiration is a common and serious problem in childhood as it requires early recognition and treatment to avoid potentially lethal consequences. This study aimed to characterize the clinical and epidemiological features of airway FBs in a pediatric Chinese population.A retrospective review of medical records of children aged 0 to 14 years who attended with a diagnosis of FB aspiration the Shanghai Children's Hospital between January 2013 and December 2017 was carried out. Descriptive analysis was used to assess patient's demographics, clinical, radiographic, bronchoscopic findings, time to presentation, and characteristics of the FBs.Among the 200 patients included in the study, 92% were under 3 years of age, with a peak incidence of FB aspiration occurring between 1 and 2 years old. The male to female ratio was about 2.6:1. Twenty-three percent of the patients were admitted within 24 hours of the event, 40% within 1 week, 30% within 1 month, and 7% more than 1 month after aspiration. The most common presenting symptoms of laryngotracheal FBs were cough, dyspnea, and wheezing; those of bronchial FBs were cough, decreased air entry, and wheezing. Chest X-ray was normal in four-fifths of the children with laryngotracheal FBs, whereas most common abnormal X-ray findings in children with bronchial FBs were mediastinal shift, obstructive emphysema, and pneumonia. There was a trend that in children younger than 2 years FBs were more frequently found in the left bronchus, whereas in older children FBs were more frequently found in the right bronchus. Ninety-three percent of the removed FBs were organic materials such as food items and the most frequently aspirated FBs were peanuts. Flexible bronchoscopy was performed in 82.5% of the patients, while rigid bronchoscopy or direct laryngoscopy in 17.5% of the patients. Four patients were subjected to thoracic surgery and 1 died during rigid bronchoscopy due to acute respiratory failure.FBs is a frequent pathology among Chinese children. Tracheobronchial FBs should be strongly suspected in young children who have sudden onset of cough and wheezing episode, even when physical and radiographic evidence is absent.

Abstract
Objective: To understand the characteristics of 24 388 inpatients with rare diseases in Zhejiang province during 2007-2017 and provide evidence for rare disease prevention and control. Methods: Inpatient data of rare diseases and the number of hospitalization in each year were collected in 10 hospitals of class Ⅲ (A) in Zhejiang province from 2007 to 2017, and descriptive statistical analysis was used. Results: A total of 24 388 cases of rare diseases were found, accounting for 2.69‰ (24 388/9 054 201) of total hospitalized cases. The top 3 types of rare diseases were "diseases of blood and blood-forming organs and certain disorders involving immune mechanism" (32.81%, 8 001/24 388), "congenital malformations, deformations and chromosomal abnormalities" (24.87%, 6 065/24 388) and "diseases of the nervous system" (19.01%, 4 635/24 388). The number of rare disease cases increased year by year from 2007 to 2017 with an average annual growth of 19.69%, however, the proportion of rare disease cases in the annual number of hospitalized cases only showed upward trend during 2016-2017, the time distribution of different types of rare diseases had different characteristics. The male to female ratio of rare diseases cases was 1.35∶1(13 990/10 398), "diseases of the digestive system" (4.45∶1, 1 180/265), "consequences of injury, poisoning and other external causes" (3.51∶1, 281/80) and "diseases of the nervous system" (2.26∶1, 3 213/1 422) had the highest male to female ratio. The distributions of rare disease types and diseases of different types in different age groups varied. The top 10 rare diseases accounted for 53.55% (13 060/24 388) of the total cases, and the top 3 diseases were adult idiopathic neutropenia (14.41%, 3 515/24 388), corticobasal degeneration (7.60%, 1 854/24 388) and henock-schoenlein purpura (6.01%, 1 466/24 388). Conclusion: The analysis on the characteristics of 24 388 rare disease cases in Zhejiang during 2007-2017 provided reference evidence for the promotion of rare disease research, monitoring, building registration database, and development of the prevention and control strategy for rare diseases in China.

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

Aims
First-phase ejection fraction (EF1), the ejection fraction up to the time of maximal ventricular contraction may be impaired in heart failure with preserved ejection fraction (HFpEF), with homeostatic mechanisms preserving the overall ejection fraction. We examined whether EF1 is impaired and whether it predicts adverse outcomes in patients with HFpEF.
Methods and Results
We examined EF1 in patients with HFpEF diagnosed according to European Society of Cardiology guidelines, in subjects with pre-clinical diastolic dysfunction and in control subjects with no evidence of heart failure. The predictive value of EF1 for a combined end-point of re-hospitalisation for heart failure and death from any cause was compared to that of conventional echocardiographic and other indices. There was a progressive impairment of EF1 in patients with diastolic dysfunction and HFpEF compared to those without evidence of heart failure (P < 0.001). In 180 HFpEF patients followed for a median of 14.7 months, 101 patients reached the primary endpoint (61 deaths and 40 hospitalisations). EF1 was the most powerful predictor of events (table 1). A cut-off value of 19.4% gave hazard ratios (for EF1 < 19.4% compared to ≥19.4%) of 3.04 (figure 1), (95% confidence interval 2.014 – 4.604, P < 0.001) unadjusted, and 2.976 (1.887 – 4.695, P < 0.001) adjusted for age, gender, other echocardiographic indices (including EF, E/e’ ratio, stroke volume and left atrial volume index) and N-terminal pro-brain natriuretic peptide.
Conclusion
Early systolic function is impaired in HFpEF and is a powerful predictor of clinical outcomes. Therapies targeted at improving early systolic function may improve outcomes in HFpEF.

Abstract
OBJECTIVE Previous study has reported that miR-330-3p was highly expressed in breast cancer (BC) patients. However, the effect of miR-330-3p in BC progression remains largely unclear. The purpose of this study was to investigate the clinical significance of miR-330-3p expression in BC. PATIENTS AND METHODS The expression of miR-330-3p was detected by quantitative Real-time PCR in BC tissues and matched normal breast tissues. The association of miR-330-3p expression with clinicopathological factors of BC patients was also analyzed by x2-test. Prognosis value of patients with BC was assessed by Kaplan-Meier method and Cox proportional hazards model, respectively. RESULTS Quantitative real-time PCR analysis showed that the expression level of miR-330-3p was significantly higher in BC specimens than that in corresponding noncancerous tissues (p < 0.01). The levels of miR-330-3p were positively correlated with the status of TNM stage (p = 0.011) and lymph node metastasis (p = 0.006). Kaplan-Meier analysis revealed that 5-year overall survival of BC patients with high miR-330-3p expression was shorter compared to those patients with low miR-330-3p expression (p < 0.0001). Moreover, univariate and multivariate regression analysis demonstrated that miR-330-3p was an independent prognostic factor in BC. CONCLUSIONS Our data suggest that miR-330-3p upregulation maybe concurrently associated with prognosis in patients with BC, suggesting that miR-330-3p may be a potential prognostic biomarker and therapeutic target for patients with BC.
