Abstract
Fly ash consists of a considerable amount of hazardous elements with high mobility, posing substantial environmental risks during storage in surface impoundments and landfills. This hinders its efficient reuse in construction or material industries. To enhance the versatility of fly ash applications, a novel surface modification technique, termed SuMo, has been developed to create a hydrophobic polysulfide polymer coating on the surface of fly ash particles. The physicochemical properties of SuMo fly ash samples were examined using atomic force microscopy (AFM), environmental scanning electron microscopy (ESEM), thermal gravimetric analysis (TGA), Fourier Transform Infrared spectroscopy (FTIR), and leaching of hazardous elements was tested under practical environmental conditions (pH 4-12) based on the EPA's leaching environmental assessment framework (LEAF). The successful coating of polysulfide polymer on fly ash surface was verified through an increased percentage of C, S, and O in elemental mapping, coupled with the identification of S-O, CO, and C-H functional groups consistent with the chemical structure of polysulfide polymer. While the SuMo fly ash particles maintained their spherical shape, they exhibited increased surface roughness, robust hydrophobicity, and thermal stability up to 250 °C. Notably, owing to the coating's resilience against water leaching, the SuMo fly ash demonstrated a substantial reduction (up to 60-fold) in leachate concentrations of multiple concerning elements, including B, Be, Ba, Mn, Zn, As, Cr, Hg, etc., under various pH conditions compared to the uncoated fly ash. Furthermore, the polysulphide polymer coating effectively prevented Hg volatilization from fly ash below 163 °C. This study highlights the efficacy of the developed polysulfide polymer coating in mitigating the diffusion of hazardous elements from fly ash, thereby enhancing its potential reutilization in material, construction, and agriculture industries.

Abstract
AIM To explore the value of multimodal magnetic resonance imaging (MRI) radiomics combined with traditional radiologist-defined semantic characteristics and conventional (cMRI) and functional MRI (fMRI) texture features in predicting Fuhrman grade of clear cell renal cell carcinoma (ccRCC). MATERIALS AND METHODS The data of 89 patients with histopathologically proven ccRCC (low-grade, 54; high-grade, 35) were collected. Texture features were extracted from cMRI (T1- and T2-weighted imaging) and fMRI (Dixon-MRI; blood-oxygen-level dependent [BOLD]-MRI; and susceptibility-weighted imaging [SWI]) images, and the traditional characteristics (TC) were evaluated. Logistic regression analysis was performed to develop models based on TC, cMRI, and fMRI texture features for grading. Receiver operating characteristic (ROC) curve analysis and leave-group-out cross-validation (LGOCV) were performed to test the reliability of combined models. RESULTS Two T2-weighted imaging-based, two Dixon_W-based, one Dixon_F-based, one BOLD-based, and three SWI-based texture features, and three TC were extracted for feature selection. TC, cMRI, fMRI, cMRI+fMRI, cMRI+TC, fMRI+TC, and cMRI+fMRI+TC models were constructed. The AUC of the cMRI+fMRI+TC model for differentiating high- from low-grade ccRCC was 0.74, with 81.42% accuracy, 75.93% sensitivity, and 91.43% specificity. The fMRI+TC model exhibited a performance similar to that of the cMRI+fMRI+TC model (p>0.05). The areas under the curve (AUCs) of the fMRI+TC and cMRI+fMRI+TC models were significantly higher than those of the other five models (all p<0.05). For the cMRI+fMRI+TC model, the mean accuracy was 85.40% after 100 LGOCV for the test sets. CONCLUSION Multimodal MRI radiomics combined with TC, cMRI, and fMRI texture features may be a reliable quantitative approach for differentiating high-grade ccRCC from low-grade ccRCC.

Abstract
To evaluate the urate-lowering effect and potential drug targets of antihypertensive agent allisartan isoproxil (ALI) and its bioactive metabolite EXP3174, we developed an acute hyperuricemic zebrafish model using potassium oxonate and xanthine sodium salt. Losartan potassium served as the positive control (reference drug). In this model, ALI and losartan potassium exerted a greater urate-lowering effect than EXP3174 indicating that the latter is not the critical substance for elimination of uric acid. The quantitative real-time PCR showed that ALI upregulates the expression of intestinal urate transporters genes ABCG2, PDZK1, and SLC2A9 (p<0.01). Thus, we can suggest that this substance promotes uric acid excretion mainly by interacting with intestinal urate transporters.

Abstract
BACKGROUND Artificial intelligence (AI) technology has clustered patients based on clinical features into sub-clusters to stratify high-risk and low-risk groups to predict outcomes in lung cancer after radiotherapy and has gained much more attention in recent years. Given that the conclusions vary considerably, this meta-analysis was conducted to investigate the combined predictive effect of AI models on lung cancer. METHODS This study was performed according to PRISMA guidelines. PubMed, ISI Web of Science, and Embase databases were searched for relevant literature. Outcomes, including overall survival (OS), disease-free survival (DFS), progression-free survival (PFS), and local control (LC), were predicted using AI models in patients with lung cancer after radiotherapy, and were used to calculate the pooled effect. Quality, heterogeneity, and publication bias of the included studies were also evaluated. RESULTS Eighteen articles with 4719 patients were eligible for this meta-analysis. The combined hazard ratios (HRs) of the included studies for OS, LC, PFS, and DFS of lung cancer patients were 2.55 (95 % confidence interval (CI) = 1.73-3.76), 2.45 (95 % CI = 0.78-7.64), 3.84 (95 % CI = 2.20-6.68), and 2.66 (95 % CI = 0.96-7.34), respectively. The combined area under the receiver operating characteristics curve (AUC) of the included articles on OS and LC in patients with lung cancer was 0.75 (95 % CI = 0.67-0.84), and 0.80 (95%CI = 0.0.68-0.95), respectively. CONCLUSION The clinical feasibility of predicting outcomes using AI models after radiotherapy in patients with lung cancer was demonstrated. Large-scale, prospective, multicenter studies should be conducted to more accurately predict the outcomes in patients with lung cancer.

Abstract
BACKGROUND Diet may influence biological aging and the discrepancy (∆age) between a subject's biological age (BA) and chronological age (CA). We aimed to investigate the correlation of dietary flavonoids with the ∆age of organs (heart, kidney, liver) and the whole body. METHOD A total of 3193 United States adults were extracted from the National Health and Nutrition Examination Survey (NHANES) in 2007-2008 and 2017-2018. Dietary flavonoids intake was assessed using 24-h dietary recall method. Multiple linear regression analysis was performed to evaluate the association of dietary flavonoids intake with the ∆age of organs (heart, kidney, liver) and the whole body. BA was computed based on circulating biomarkers, and the resulting ∆age was tested as an outcome in linear regression analysis. RESULTS The ∆age of the whole body, heart, and liver was inversely associated with higher flavonoids intake (the whole body ∆age β = - 0.58, cardiovascular ∆age β = - 0.96, liver ∆age β = - 3.19) after adjustment for variables. However, higher flavonoids intake positively related to renal ∆age (β = 0.40) in participants with chronic kidney disease (CKD). Associations were influenced by population characteristics, such as age, health behavior, or chronic diseases. Anthocyanidins, isoflavones and flavones had the strongest inverse associations between the whole body ∆age and cardiovascular ∆age among all the flavonoids subclasses. CONCLUSION Flavonoids intake positively contributes to delaying the biological aging process, especially in the heart, and liver organ, which may be beneficial for reducing the long-term risk of cardiovascular or liver disease.

Abstract
Background The healthiest way to prevent metabolic syndrome (MetS) is through behavioral and nutritional adjustments. We examined the relationship between total flavonoids intake, flavonoid subclasses, and clinically manifest MetS. Methods A cross-sectional analysis was conducted among 28,719 individuals from the National Health and Nutrition Examination Survey (NHANES) and Food and Nutrient Database for Dietary Studies (FNDDS) 2007-2011 and 2017-2018. Two 24-h reviews were conducted to determine flavonoids intake and subclasses. The link between flavonoids intake and MetS was investigated using a multivariate logistic regression model. Results Q2 and Q3 of total flavonoids intake were associated with 20 and 19% lower risk of incident MetS after adjusting age and sex. Anthocyanidins and flavanones intake in Q2 and Q3 substantially reduced the MetS risk compared to Q1. MetS risk decreased steadily as the total intake of flavonoids increased to 237.67 mg/d. Flavanones and anthocyanidins also displayed V-shaped relationship curves (34.37 and 23.13 mg/d). Conclusion MetS was adversely linked with total flavonoids intake, flavanones, and anthocyanidins. Moreover, the most effective doses of total flavonoids, flavanones, and anthocyanidins were 237.67, 34.37, and 23.13 mg/d, respectively, potentially preventing MetS.

Abstract
Aim: We aimed to analyze efficacy and adverse events for nano-bound paclitaxel in cancer treatment, which remain controversial. Method: We obtained relevant previously published studies and extracted data on the efficacy and adverse events of nano-bound paclitaxel. Fifteen randomized clinical trials were included. Results: Nanoparticle albumin-bound (Nab-) paclitaxel was beneficial in terms of objective response rate (odds ratio [OR]: 1.08, 95% CI: 0.72-1.62) and partial response (OR: 1.28, 95% CI: 0.89-1.83), while polymeric micellar (PM-) paclitaxel was beneficial in terms of objective response rate (OR: 1.76) and partial disease (hazard ratio [HR]: 0.65). Both Nab-paclitaxel and PM-paclitaxel resulted in slightly longer overall survival (HR: 0.93 and 0.94) and progression-free survival (HR: 0.93 and 0.87) when compared with solvent-based paclitaxel. Peripheral sensory neuropathy (OR: 3.47), neutropenia (OR: 1.79) and anemia (OR: 1.79) were more frequent after Nab-paclitaxel treatment. Conclusion: Nano-paclitaxel formulations have a better efficacy in cancer treatment; however, they increase the risk of hematological adverse events and peripheral sensory neuropathy. The PM-paclitaxel treatment had a high safety effect.

Abstract
Organic-inorganic hybrid perovskite (OIHP) polycrystalline thin films are attractive due to their outstanding photoelectronic properties. The anti-solvent spin coating method is the most widely used to synthesize these thin films, and the residual strain is inevitably originates and evolves during the process. However, this residual strain evolution induced by crystallization kinetics is still poorly understood. In this work, the in situ and ex situ synchrotron grazing-incidence wide-angle X-ray scattering (GIWAXS) are utilized to characterize the evolution and distribution of the residual strain in the OIHP polycrystalline thin film during the anti-solvent spin coating process. A mechanical model is established and the mechanism of the crystallization kinetics-induced residual strain evolution process is discussed. This work reveals a comprehensive understanding of the residual strain evolution during the anti-solvent spin coating process in the OIHP polycrystalline thin films and provides important guidelines for the residual strain-related strain engineering, morphology control, and performance enhancement.

Abstract
Many biomolecular condensates appear to form through liquid-liquid phase separation (LLPS). Individual condensate components can often undergo LLPS in vitro, capturing some features of the native structures. However, natural condensates contain dozens of components with different concentrations, dynamics, and contributions to compartment formation. Most biochemical reconstitutions of condensates have not benefited from quantitative knowledge of these cellular features nor attempted to capture natural complexity. Here, we build on prior quantitative cellular studies to reconstitute yeast RNA processing bodies (P bodies) from purified components. Individually, five of the seven highly concentrated P-body proteins form homotypic condensates at cellular protein and salt concentrations, using both structured domains and intrinsically disordered regions. Combining the seven proteins together at their cellular concentrations with RNA yields phase-separated droplets with partition coefficients and dynamics of most proteins in reasonable agreement with cellular values. RNA delays the maturation of proteins within and promotes the reversibility of, P bodies. Our ability to quantitatively recapitulate the composition and dynamics of a condensate from its most concentrated components suggests that simple interactions between these components carry much of the information that defines the physical properties of the cellular structure.

Abstract
Background Previous studies suggested that gut dysbacteriosis may promote the occurrence of chronic kidney disease (CKD), and probiotic, prebiotic, or yogurt supplements may alleviate CKD progression. This study aims to examine the association between probiotic, prebiotic, or yogurt supplements and the risk of CKD using the data from NHANES. Methods This study was designed to prospectively search data from the National Health and Nutrition Examination Survey (NHANES) (2011-2020). We examined dietary supplements and prescription medication labels to identify probiotic, or prebiotic product, and yogurt consumption during the dietary interview. The diagnosis of CKD was determined by the value of glomerular filtration rate (eGFR) and albumin creatinine ratio (ACR). Results The study enrolled a total of 6,522 individuals. The prevalence of CKD was lower in the probiotic, prebiotic, or yogurt consumption group [age-adjusted odds ratio (OR): 0.77, 95% CI: 0.62-0.95, P = 0.02; multivariable-adjusted OR: 0.86, 95% CI: 0.69-1.07, P = 0.05]. Furthermore, 32% reduced risk was observed in the older group aged 55 years or older, and 32% reduced risk was also observed in the female population. Probiotic, or prebiotic, or yogurt supplements was associated a 12% reduction in moderate risk of CKD and an 11% reduction in very high risk of CKD. Conclusion Our results suggest that probiotic, prebiotic, or yogurt supplements may contribute to the prevention of CKD and relieve its progression risk, especially in the female population and older population who were aged 55 years or older.

Abstract
BACKGROUND Non-alcoholic fatty liver disease (NAFLD) is the most prevalent chronic liver disease. Research on the efficacy of probiotics, prebiotics, and synbiotics on NAFLD patients continues to be inconsistent. The purpose of this study is to evaluate the effectiveness of these microbial therapies on NAFLD. METHODS Eligible randomized-controlled trials reporting the effect of probiotics, prebiotics, or synbiotics in NAFLD were searched in PubMed, Web of Science, Embase, Google scholar, and CNKI databases from 2020 to Jul 2022. The changes in the outcomes were analyzed using standard mean difference (SMD) and 95% confidence intervals (CIs) with a random- or fixed-effects model to examine the effect of microbial therapies. Subgroup analysis, influence and publication bias analysis were also performed. The quality of the eligible studies was evaluated using the Cochrane Risk of Bias Tool. RESULTS Eleven studies met the inclusion criteria involving 741 individuals. Microbial therapies could improve liver steatosis, total cholesterol (TC), triglyceride (TG), low-density lipoprotein (LDL-c), alanine aminotransferase (ALT), alkaline phosphatase (ALP), glutamyl transpeptidase (GGT), and homeostasis model assessment-insulin resistance (HOMAI-R) (all P < 0.05). But microbial therapies could not ameliorate body mass index (BMI), energy, carbohydrate, fat intake, fasting blood sugar, HbA1c, insulin, high-sensitivity C-reactive protein (hs-CRP), and hepatic fibrosis of patients with NAFLD. CONCLUSION Probiotics, prebiotics, and synbiotics supplementation can potentially improve liver enzymes, lipid profiles, and liver steatosis in patients with NAFLD.

Abstract
The increasing prevalence of non-alcoholic fatty liver disease (NAFLD), which is a progressive disease, has exerted huge a healthcare burden worldwide. New investigations have suggested that the gut microbiota closely participates in the progression of NAFLD through the gut–liver axis or gut–brain–liver axis. The composition of the microbiota can be altered by multiple factors, primarily dietary style, nutritional supplements, or exercise. Recent evidence has revealed that gut microbiota is involved in mitochondrial biogenesis and energy metabolism in the liver by regulating crucial transcription factors, enzymes, or genes. Moreover, microbiota metabolites can also affect mitochondrial oxidative stress function and swallow formation, subsequently controlling the inflammatory response and regulating the levels of inflammatory cytokines, which are the predominant regulators of NAFLD. This review focuses on the changes in the composition of the gut microbiota and metabolites as well as the cross-talk between gut microbiota and mitochondrial function. We thus aim to comprehensively explore the potential mechanisms of gut microbiota in NAFLD and potential therapeutic strategies targeting NAFLD management.

Abstract
BackgroundEarly identification of Alzheimer’s disease or mild cognitive impairment can help guide direct prevention and supportive treatments, improve outcomes, and reduce medical costs. Existing advanced diagnostic tools are mostly based on neuroimaging and suffer from certain problems in cost, reliability, repeatability, accessibility, ease of use, and clinical integration. To address these problems, we developed, evaluated, and implemented an early diagnostic tool using machine learning and non-imaging factors.Methods and resultsA total of 654 participants aged 65 or older from the Nursing Home in Hangzhou, China were identified. Information collected from these patients includes dementia status and 70 demographic, cognitive, socioeconomic, and clinical features. Logistic regression, support vector machine (SVM), neural network, random forest, extreme gradient boosting (XGBoost), least absolute shrinkage and selection operator (LASSO), and best subset models were trained, tuned, and internally validated using a novel double cross validation algorithm and multiple evaluation metrics. The trained models were also compared and externally validated using a separate dataset with 1,100 participants from four communities in Zhejiang Province, China. The model with the best performance was then identified and implemented online with a friendly user interface. For the nursing dataset, the top three models are the neural network (AUROC = 0.9435), XGBoost (AUROC = 0.9398), and SVM with the polynomial kernel (AUROC = 0.9213). With the community dataset, the best three models are the random forest (AUROC = 0.9259), SVM with linear kernel (AUROC = 0.9282), and SVM with polynomial kernel (AUROC = 0.9213). The F1 scores and area under the precision-recall curve showed that the SVMs, neural network, and random forest were robust on the unbalanced community dataset. Overall the SVM with the polynomial kernel was found to be the best model. The LASSO and best subset models identified 17 features most relevant to dementia prediction, mostly from cognitive test results and socioeconomic characteristics.ConclusionOur non-imaging-based diagnostic tool can effectively predict dementia outcomes. The tool can be conveniently incorporated into clinical practice. Its online implementation allows zero barriers to its use, which enhances the disease’s diagnosis, improves the quality of care, and reduces costs.

Abstract
Background Radioresistance is the major obstacle after cancer radiotherapy. The dysregulation of long non-coding RNAs (lncRNAs) was closely related the radioresistance response. This meta-analysis was aimed to interpret the relationship between lncRNAs and radiotherapy responses in different cancers. Method The studies were selected from databases including PubMed, ISI Web of Science, Embase, Google Scholar, PMC, and CNKI (China National Knowledge Infrastructure). The publication time was limited to before March 20, 2021. The hazard ratios (HRs) and 95% confidence interval were calculated with random-effects models. Subgroup analyses, sensitivity analyses, and publication bias were also conducted. Result Twenty-seven lncRNAs in 14 cancer types were investigated, in which 23 lncRNAs were upregulated and four lncRNAs were downregulated. Dysregulation of these lncRNAs were found to be related to radioresistance response. The pooled HR and 95% confidence interval for the combined up-regulated lncRNAs was 1.73 (95% CI=1.50-2.00; P< 0.01) and down-regulated lncRNAs was 2.09 (95% CI= 1.60-2.72; P< 0.01). The HR values of the subgroup analysis for glioma (HR= 2.22, 95% CI= 1.79-2.74; p< 0.01), non-small cell lung cancer (HR=1.48, 95% CI=1.18-1.85; P<0.01), nasopharyngeal carcinoma (HR=4.26; 95% CI= 1.58-11.46; P< 0.01), and breast cancer (HR=1.29; 95% CI= 1.08-1.54; P< 0.01) were obtained. Moreover, the expression of lncRNAs was significantly related to overall survival of patients no matter if the sample size was >50 or not. In addition, the HR values of the subgroup analysis for lncRNA H19 (HR=2.68; 95% CI= 1.92-3.74; P <0.01), lncRNA FAM201A (HR=2.15; 95% CI= 1.15-3.99; P <0.01), and lncRNA HOTAIR (HR=1.22; 95% CI= 0.98-1.54; P =0.08) were also obtained. Conclusion LncRNAs can induce cancer radioresistance by regulating cell death-related signaling pathways. Results indicated that lncRNAs, especially lncRNA H19, FAM201A, and HOTAIR, could be considered as a predictive theragnostic biomarker to evaluate radiotherapy response.

Abstract
OBJECTIVES Little is known regarding fetal growth patterns in monochorionic twin pregnancy complicated by Type-III selective fetal growth restriction (sFGR). We aimed to assess fetal growth and umbilical artery Doppler pattern in Type-III sFGR across gestation and evaluate the effect of changing Doppler flow pattern on growth and intertwin growth discordance. METHODS This was a retrospective cohort study of all Type-III sFGR pregnancies managed at nine fetal centers over a 12-year time period. Higher-order multiple pregnancy and cases with major fetal anomaly or other monochorionicity-related complications at presentation were excluded. Estimated fetal weight (EFW) was assessed on ultrasound for each twin pair at five timepoints (16-20, 21-24, 25-28, 29-32 and > 32 weeks' gestation) and compared with singleton and uncomplicated monochorionic twin EFW. EFW and intertwin EFW discordance were compared between pregnancies with normalization of umbilical artery Doppler of the smaller twin later in pregnancy and those with persistently abnormal Doppler. RESULTS Overall, 328 pregnancies (656 fetuses) met the study criteria. In Type-III sFGR, the smaller twin had a lower EFW than an average singleton fetus (EFW Z-score ranging from -1.52 at 16 weeks to -2.69 at 36 weeks) and an average monochorionic twin in uncomplicated pregnancy (Z-score ranging from -1.73 at 16 weeks to -1.49 at 36 weeks) throughout the entire gestation, while the larger twin had a higher EFW than an average singleton fetus until 22 weeks' gestation and was similar in EFW to an average uncomplicated monochorionic twin throughout gestation. As pregnancy advanced, growth velocity of both twins decreased, with the larger twin remaining appropriately grown and the smaller twin becoming more growth restricted. Intertwin EFW discordance remained stable throughout gestation. On multivariable longitudinal modeling, normalization of fetal umbilical artery Doppler was associated with better growth of the smaller twin (P = 0.002) but not the larger twin (P = 0.1), without affecting the intertwin growth discordance (P = 0.09). CONCLUSIONS Abnormal fetal growth of the smaller twin in Type-III sFGR was evident early in pregnancy, while EFW of the larger twin remained normal throughout gestation. Normalization of umbilical artery Doppler was associated with improved fetal growth of the smaller twin. © 2021 International Society of Ultrasound in Obstetrics and Gynecology.

Abstract
OBJECTIVE To systematically evaluate the effectiveness of balneotherapy and/or aquatic exercise on bone metabolism. DESIGN A systematic literature search was conducted from inception to January 4, 2021. Standardized mean differences (SMDs) and 95% confidence intervals (CIs) were calculated using a fixed-effect model according to study heterogeneity. RESULTS Seven articles involving 467 participants were selected. Three balneotherapy studies were qualitatively integrated. The results showed that bone resorption slowed down with or without stimulation of bone formation. A pooled meta-analysis of four studies on aquatic exercise showed significant evidence for a reduction in parathyroid hormone (PTH; SMD = -0.71; 95% CI, -1.04 to -0.38; P < 0.001), and a significant increase in osteocalcin (OC; SMD = 0.60; 95% CI, 0.16 to 1.03; P = 0.007) after aquatic exercise. CONCLUSION Balneotherapy and aquatic exercise had significant effects on bone metabolism, reducing bone resorption and/or increasing bone formation. This study highlights the importance of balneotherapy and aquatic exercise for bone health.

Abstract
Background: Alzheimer's disease (AD) diagnoses once depended on neuropathologic examination. Now, many widely used, validated biomarkers benefits for monitoring of AD neuropathologic changes. Exosome-derived biomarker studies have reported them to be significantly related to AD's early occurrence and development, although the findings are inconclusive. The aim of this meta-analysis was to identify exosome-derived biomarkers for the diagnosis of AD and mild cognitive impairment (MCI). Methods: PubMed, PubMed Central, Web of Science, Embase, Google Scholar, Cochrane Library, the Chinese National Knowledge Infrastructure (CNKI), and the Chinese Biomedical Literature Database (CBM) were searched for studies assessing the diagnostic value of biomarkers, including data describing the pooled sensitivity (SEN), specificity (SPE), positive diagnostic likelihood ratio (DLR+), negative diagnostic likelihood ratio (DLR–), diagnostic odds ratio (DOR), and area under the curve (AUC). The quality of the included studies was assessed using RevMan 5.3 software. Publication bias was analyzed. Results: In total, 19 eligible studies, including 3,742 patients, were selected for this meta-analysis. The SEN, SPE, DLR+, DLR–, DOR, and AUC (95% confidence intervals) of exosome-derived biomarkers in the diagnosis of AD or MCI were 0.83 (0.76–0.87), 0.82 (0.77–0.86), 4.53 (3.46–5.93), 0.21 (0.15–0.29), 17.27 (11.41–26.14), and 0.89 (0.86–0.92), respectively. Sub-group analyses revealed that studies based on serum or microRNA (miRNA) analysis, and those of Caucasian populations, AD patients, patient sample size >50, neuron-derived exosomes (NDE) from plasma and p-tau had higher sensitivity, specificity, and AUC values. Conclusion: Exosome-derived biomarkers have shown potential diagnostic value in AD and MCI, although further research is required for confirmation.

Abstract
AIM To evaluate the value of high-resolution magnetic resonance imaging of the vessel wall (VWI) for differentiating moyamoya disease (MMD) from atherosclerotic moyamoya syndrome (AS-MMS). MATERIALS AND METHODS Twenty-one patients with MMD or AS-MMS were assessed retrospectively by two independent raters regarding and magnetic resonance angiography (MRA) stage grading score; collateral development in the lateral fissure and basal ganglia on MRA; and pattern of the thickening of the arterial wall; presence, degree, and pattern of enhancement; presence and distribution of deep tiny flow voids (DTFVs) and collateral development in the lateral fissure and basal ganglia on VWI. After univariate analysis between the two groups, logistic regression models based on imaging findings of MRA or VWI were implemented respectively, and receiver operating characteristic (ROC) curves were generated to compare the discriminatory power of the two imaging methods for diagnosis of MMD. Interrater agreement was analysed using an unweighted Cohen's κ or interclass correlation coefficient (ICC). RESULTS MMD manifested as more concentric thickening, more homogeneous enhancement, higher presence of DTFV, smaller outer-wall boundary area of stenosis or occlusion, and smaller remodelling index on VWI. After Bonferroni-Holm correction for multiple comparisons, for AS-MMS, collaterals in both the lateral fissure and basal ganglia were not usually present on either MRA or VWI. The diagnostic performance of the multivariate logistic regression model based on VWI with an accuracy of 87.1% for classification was higher than MRA. Interrater agreement was moderate or substantial for all the imaging findings. CONCLUSIONS VWI might be a useful and feasible method for differentiating MMD from AS-MMS and a prospective tool for guiding first-line treatment.

Abstract
OBJECTIVE Type-III selective intrauterine growth restriction (sIUGR) is associated with a high and unpredictable risk of fetal death and fetal brain injury. The objective of this study was to describe the prospective risk of fetal death and the risk of adverse neonatal outcome in a cohort of twin pregnancies complicated by Type-III sIUGR and treated according to up-to-date guidelines. METHODS We reviewed retrospectively all monochorionic diamniotic twin pregnancies complicated by Type-III sIUGR managed at nine fetal centers over a 12-year period. Higher-order multiple gestations and pregnancies with major fetal anomalies or other monochorionicity-related complications at initial presentation were excluded. Data on fetal and neonatal outcomes were collected and management strategies reviewed. Composite adverse neonatal outcome was defined as neonatal death, invasive ventilation beyond the resuscitation period, culture-proven sepsis, necrotizing enterocolitis requiring treatment, intraventricular hemorrhage Grade > I, retinopathy of prematurity Stage > II or cystic periventricular leukomalacia. The prospective risk of intrauterine death (IUD) and the risk of neonatal complications according to gestational age were evaluated. RESULTS We collected data on 328 pregnancies (656 fetuses). After exclusion of pregnancies that underwent selective reduction (n = 18 (5.5%)), there were 51/620 (8.2%) non-iatrogenic IUDs in 35/310 (11.3%) pregnancies. Single IUD occurred in 19/328 (5.8%) pregnancies and double IUD in 16/328 (4.9%). The prospective risk of non-iatrogenic IUD per fetus declined from 8.1% (95% CI, 5.95-10.26%) at 16 weeks, to less than 2% (95% CI, 0.59-2.79%) after 28.4 weeks and to less than 1% (95% CI, -0.30 to 1.89%) beyond 32.6 weeks. In otherwise uncomplicated pregnancies with Type-III sIUGR, delivery was generally planned at 32 weeks, at which time the risk of composite adverse neonatal outcome was 29.0% (31/107 neonates). In twin pregnancies that continued to 34 weeks, there was a very low risk of IUD (0.7%) and a low risk of composite adverse neonatal outcome (11%). CONCLUSIONS In this cohort of twin pregnancies complicated by Type-III sIUGR and treated at several tertiary fetal centers, the risk of fetal death was lower than that reported previously. Further efforts should be directed at identifying predictors of fetal death and optimal antenatal surveillance strategies to select a cohort of pregnancies that can continue safely beyond 33 weeks' gestation. © 2020 International Society of Ultrasound in Obstetrics and Gynecology.

Abstract
INTRODUCTION Elevated blood pressure (BP) is a leading risk factor for many chronic diseases. Many investigations conducted using telemedicine (TM)-based interventions have the potential to control BP. The purpose of this study was to assess the efficacy of TM-based interventions in reducing BP. METHODS Studies were selected from PubMed, PMC, Web of Science, Embase, Google Scholar, Cochrane Library, the Chinese National Knowledge Infrastructure (CNKI) and the Chinese Biomedical Literature Database (CBM) according to the inclusion and exclusion criteria. The mean and standard deviation changes in systolic BP (SBP) and diastolic BP (DBP) were analysed using standard mean difference (SMD) and 95% confidence intervals (CI) with a random-effects model or fixed-effects model to assess the efficiency of controlling BP. Subgroup analysis, influence analysis and publication bias analysis were also conducted. RESULTS Sixteen randomised clinical trials were included in this meta-analysis. A TM-based lifestyle intervention significantly reduced daytime SBP (SMD = -0.18, 95% CI -0.27 to -0.10; p < 0.001) and DBP (SMD = -0.18, 95% CI -0.27 to -0.09; p < 0.001). The results of subgroup analysis indicated that this reduction in BP was reliable when BP interventions lasted for 6 months or longer in populations with cardiovascular disease and hypertension. Moreover, the detection data should be delivered by a device system to ensure accuracy. DISCUSSION A TM-based intervention could reduce daytime SBP and DBP in populations with hypertension and cardiovascular disease. This review provides intuitive evidence of a reduction in BP using TM-based interventions.

Abstract
BACKGROUND Neurofilament light (NfL) level was obviously increased in traumatic brain injury (TBI) individuals. But, no comprehensive meta-analysis has ever been conducted to assess the diagnostic performance of NfL. This study aims to evaluate the relationship between NfL level and TBI through a meta-analysis. METHODS Studies were selected from Pubmed, Web of science, Embase, Google Scholar, PMC and Chinese National Knowledge Infrastructure (CNKI), and the Chinese Biomedical Literature Database (CBM) through inclusion and exclusion criteria. The standard mean difference (SMD) and 95% confidence interval (CI) were calculated using the random-effect model or fixed-effect model to assess the association between NfL level and TBI. Subgroup analysis according to sample collection time, sample type and detection method was performed. The influence analysis and publication bias was also conducted. All analyses were performed using the RevMan 5.3 and Stata 12 software. RESULTS A total of 9 studies were included. Results indicated that TBI individuals had a higher NfL expression level compared with the non-TBI individuals (SMD = 2.48, 95% CI = 1.52-3.43, I = 96%, P < .01). Similar NfL increasing was also observed in Caucasian population, 0-48 hour and 6-10 days sample collection time, as well as cerebrospinal fluid (CSF), serum, plasma sample subgroup analysis. Moreover, the NfL increasing still existed no matter the NfL expression level was detected by ELISA or Simoa assay. CONCLUSION NfL expression level was increased in TBI individuals, which indicated that NfL could be a potential biomarker in the diagnosis of TBI and other neurodegenerative diseases.

Abstract
P bodies are archetypal biomolecular condensates that concentrate proteins and RNA without a surrounding membrane. While dozens of P body proteins are known, the concentrations of components in the compartment have not been measured. We used live cell imaging to generate a quantitative inventory of the major proteins in yeast P bodies. Only seven proteins are highly concentrated in P bodies (5.1–15µM); the 24 others examined are appreciably lower (most ≤ 2.6µM). P body concentration correlates inversely with cytoplasmic exchange rate. Sequence elements driving Dcp2 concentration into P bodies are distributed across the protein and act synergistically. Our data indicate that P bodies, and probably other condensates, are compositionally simpler than suggested by proteomic analyses, with implications for specificity, reconstitution and evolution.

Abstract
Objective: To explore the value of magnetic resonance imaging (MRI) texture analysis in evaluating renal allograft injury. Methods: A retrospective review was performed on sixty-six patients who underwent allograft renal transplantation (42 males, 24 females; age range, 22-63 years; mean age, (40±10) years) between November 2013 and December 2016. All the patients were divided into three groups according to their eGFR on the day of MRI examination: normal renal allograft function (nRAF) group (n=15), mild to moderate renal allograft injury (mRAI) group (n=18), and severe renal allograft injury (sRAI) group (n=33). All the patients underwent conventional T(2) weighted image (T(2)WI), susceptibility weighted imaging (SWI), and blood-oxygen level dependent (BOLD) MRI examination. MRI texture features of renal allograft were extracted. The texture features based on T(2)WI, SWI, and BOLD with absolute correlation coefficient of eGFR greater than or equal to 0.3 (P<0.05)and also with the highest Z value for Boruta algorithmwere selected. The diagnostic performance of the selected texture features in differentiating the three groups was assessed by receiver operating characteristic (ROC) curve analysis. Results: T(2)WI_Perc.50%, SWI_Perc.01%, BOLD_S(4,4)Contrast, and BOLD_S(5,5)Correlat with absolute correlation coefficient of eGFR greater than or equal to 0.3 (P<0.05) and also with the highest Z value for Boruta algorithm were selected. The AUC for T(2)WI_Perc.50%, SWI_Perc.01%, and BOLD_S(5,5)Correlat in differentiating the nRAF group with the mRAI group was 0.785, 0.720, and 0.700. The AUC for T(2)WI_Perc.50%, SWI_Perc.01%, BOLD_S(4,4)Contrast, and BOLD_S(5,5)Correlat in differentiating the nRAF group with the sRAI group was 0.687, 0.733, 0.784, and 0.737.The AUC for BOLD_S(4,4) Contrast in differentiating the mRAI group with the sRAI group was 0.667. Conclusion: MRI texture analysis can provide valuable information for evaluating renal allograft injury.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Andrographis paniculata (AP) is a native plant with anti-inflammatory and antioxidant properties and used as an official herbal medicine. Recently more and more researches have indicated that AP shows pharmacological effects on Alzheimer's disease (AD) but its mechanism is unclear. AIMS OF THE STUDY Network pharmacology approach combined with experimental validation was developed to reveal the underlying molecular mechanisms of AP in treating AD. MATERIALS AND METHODS The compounds of AP from TCM database, the AD-related targets from disease database and the targets corresponding to compounds from swissTargetPrediction were collected. Then DAVID database was used for annotation and enrichment pathways, meanwhile the compound-target, protein-protein interaction from String database and compound-target-pathway network was constructed, molecular modeling was performed using Sybyl-x. Okadaic acid (OKA)-induced cytotoxicity model in PC12 cells was established to verify the mechanism of AP and the key proteins were detected by western blotting. RESULTS 28 AP components were identified after ADME filter analysis and 52 targets were gained via mapping predicted targets into AD-related proteins. In addition, after multiple network analysis, the 22 hub target genes were enriched onto pathways involved in AD, such as neuroactive ligand-receptor interaction, serotonergic synapse, Alzheimer's disease, PI3K-Akt and NF-kB signaling pathway. Interestingly, molecular docking simulation revealed that the targets including PTGS2, BACE1, GSK3B and IKBKB had good ability to combine with AP components. Experimental validation in an in vitro system proved that AP treatment obviously increased in levels inactive of p-GSK3β (P < 0.05) and decreased in levels of BACE (P < 0.05), PTGS2 (namely COX2, P < 0.05) and NF-kB protein (P < 0.05) compare with OKA treated group. CONCLUSION Our data provided convincing evidence that the neuroprotective effects of AP might be partially related to their regulation of the APP-BACE1-GSK3B signal axis and inflammation, which should be the focus of study in this field in the future.

Abstract
OBJECTIVE Many findings have demonstrated long noncoding RNAs (lncRNAs) as crucial regulatory molecules in the progression of osteosarcoma. The aim of this study was to explore the roles and mechanisms of LncRNA LINC00689 (LINC00689) in osteosarcoma. PATIENTS AND METHODS Differential levels of LINC00689 and miR-655 in osteosarcoma samples and cell lines were analyzed by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). The associations between LINC00689 expression and prognostic significance of osteosarcoma patients were analyzed using a series of statistical assays. Loss-of-function and gain-of-function assays were performed to investigate the role of LINC00689 in proliferation and metastasis in vitro. Bioinformatic assays, Luciferase report assays, and rescue assays were applied to illustrate the ceRNA mechanism network of LINC00689/miR-655/SOX18. RESULTS We found that LINC00689 expression was distinctly upregulated in osteosarcoma specimens and cell lines. MiR-655 displayed a trend of remarkably decreased expression in osteosarcoma tissues. In addition, we showed that LINC00689 could specifically interact with the promoter of SP1 and activate LINC00689 transcription. Further clinical studies indicated that higher levels of LINC00689 were associated with advanced clinical stage, positively distant metastasis, and unfavorable clinical outcome. Functional studies revealed that the knockdown of LINC00689 suppressed the proliferation, migration, and invasion of osteosarcoma cells, and promoted apoptosis. Final mechanistic investigations confirmed that upregulation of LINC00689 competitively bound to miR-655 that prevented SOX18 from miRNA-mediated degradation, thus facilitating osteosarcoma progression. CONCLUSIONS All our findings suggested that SP1-induced upregulation of LINC00689 promoted osteosarcoma progression by regulating miR-655/ SOX18 axis, which provided a novel insight for osteosarcoma tumorigenesis.

Abstract
:
For decades now, compounds in the cycloartane-type series have been shown to
have versatile pharmacological activities. However, no extensive review has been written
to summarize these health-beneficial activities. Therefore, the purpose of this paper is to
systematically highlight the biological activities of these compounds, including their antitumor
and anti-osteoporosis effects, their effects on receptors, cytokine release, and
chronic renal failure, as well as their tyrosinase inhibitory, anticomplement, anti-parasite,
anti-HIV, and antituberculosis activities. In this review, we have summarized the structures
of over 200 compounds based on their characteristics and described their structureactivity
relationships (SARs), and potential mechanisms of action.

Abstract
Objective: To investigate the value of quantitative and semiquantitative parameters of DCE-MRI in predicting IDH gene mutation of high-grade gliomas before the operation. Methods: Twenty-six individuals with surgically and pathologically proved WHO Ⅲ-Ⅳ gliomas collected from April 2016 to June 2019 in First People's Hospital of Changzhou, were divided into two groups, IDH mutation group (7 cases, 27-67 years, 3 males and 4 females,) and IDH gene wild group (19 cases, 42-75 years, 12 males and 7 females) according to the results of molecular pathology. All individuals underwent conventional plain (T(1)WI, T(2)WI), enhanced MR scanning (T(1)WI) and dynamic contrast enhancement (DCE). Four quantitative parameters:volume transfer constant (K(trans)), ratio constant of back flux (Kep), extravascular extracellular space fractional volume (Ve), and blood plasma fractional volume (Vp), and four semiquantitative parameters: time to peak (TTP), maximum concentration (MAX Conc), initial area under the gadolinium concentration-time curve (IAUC) and maximum slope of decrease (MAX Slope) were measured. The independent samples t test (normal distribution and homogeneity of variance) or Mann-Whitney rank sum test (abnormal distribution or heterogeneity of variance) were used to compare the differences of quantitative and semiquantitative parameters between IDH gene mutation group and IDH gene wild type group. Receiver operating characteristic (ROC) curve was used to evaluate the efficiency of quantitative and semiquantitative parameters in predicting IDH gene mutation of high-grade gliomas. Results: The value of K(trans),TTP in IDH mutated group were 0.096 (0.080,0.135)/min and (3.95±0.34) s, respectively. The value of K(trans), TTP in IDH wild type group were 0.168 (0.132, 0.337)/min and (2.58±1.15) s, respectively. The value of K(trans) in IDH mutated group was significantly less than the value of K(trans) in IDH gene wild type group (Z value was -2.168, P value was 0.030). The value of K(trans) in IDH mutated group was significantly greater than the value of K(trans) in IDH gene wild type (Z value was -2.630, P value was 0.007). The area under the ROC curve (AUC) of K(trans) and TTP in predicting IDH gene mutation of high-grade gliomas was 0.782 and 0.842, respectively. The specificity of K(trans) was higher (73.7%), The sensitivity of TTP was the higher (100.0%). Combined K(trans)and TTP were the best for predicting IDH gene mutation of high-grade gliomas, AUC was 0.865. Conclusion: Quantitative and semiquantitative parameters of DCE-MRI can help to predict IDH gene mutation of high-grade gliomas before the operation.

Abstract
Objective: To investigate the feasibility of blood oxygen level-dependent magnetic resonance imaging (MRI) in evaluating the response of metastatic lymph nodes of rabbit VX2 tumor to radiotherapy. Methods: Twenty-eight healthy New Zealand white rabbits which were provided by the Laboratory Animal Center of Soochow University, male or female, 2 to 3 months, weighing 2 to 3 kg, were used to establish the animal model of VX2 tumor popliteal fossa metastatic lymph node, and then were divided into either the radiotherapy group (n=16) or the control group (n=12). The radiotherapy group received a 20 Gy radiotherapy per rabbit, the control group received sham radiotherapy. All rabbits underwent MRI scan on four time points, including before (0 day), 3rd, 7th and 14th days after radiotherapy. The two parameters of size and R(2*) value (s(-1)) of lymph node were measured. At each time point,two rabbits in each group were sacrificed randomly to resect lymph nodes for pathological examination, and two parameters of microvessel density (MVD, strip/HP) and apoptosis index (AI, %) were analyzed. The parameters among the four time points in each group or between the two groups were compared. The correlation of lymph node size and R(2*) value with MVD or AI was analyzed, respectively. Results: A significant size difference was neither between the two groups or among the each time points in each group (P>0.05). The R(2*) of lymph node in the radiotherapy group was (29.6±1.7),(36.8±2.6),(44.8±5.8) and (57.7±6.2) s(-1) at the time points of 0, 3, 7 and 14 days, respectively, showing a gradual increase trend; MVD was (52.3±2.5),(41.0±3.6),(34.0±3.6) and (22.7±2.5) strip/HP respectively, showing a decreasing trend; AI was 12.8%±0.5%,14.9%±0.6%,20.6%±0.5% and 27.5%±0.7% respectively, showing a gradual increase trend (all P<0.05). In the control group, both R(2*) value and AI among the four time points did not change statistically (all P>0.05), but MVD showed a gradual increase trend,(50.0±3.0),(53.0±1.7),(60.3±2.5) and (70.0±2.0) strip/HP, respectively, P<0.05. There were significant differences in R(2*) and MVD at 3, 7 and 14 days, in AI at 7 and 14 days between the two groups (all P<0.05). There was a linear correlation of R(2*) value, but not of size, with MVD and AI (r=-0.87 and 0.94, respectively). Conclusion: Blood oxygen level-dependent MRI can indirectly reflect the hypoxic status of metastatic lymph nodes after radiotherapy, and has potential value in evaluating the response of metastatic lymph nodes to radiotherapy.

Abstract
In this paper, we develop a surrogate modelling approach for capturing the output field (e.g. the pressure head) from groundwater flow models involving a stochastic input field (e.g. the hydraulic conductivity). We use a Karhunen–Loève expansion for a log-normally distributed input field and apply manifold learning (local tangent space alignment) to perform Gaussian process Bayesian inference using Hamiltonian Monte Carlo in an abstract feature space, yielding outputs for arbitrary unseen inputs. We also develop a framework for forward uncertainty quantification in such problems, including analytical approximations of the mean of the marginalized distribution (with respect to the inputs). To sample from the distribution, we present Monte Carlo approach. Two examples are presented to demonstrate the accuracy of our approach: a Darcy flow model with contaminant transport in 2-d and a Richards equation model in 3-d.

Abstract
Preterm birth (PTB), accompanied by low birth weight (LBW) or not, is a syndrome with tremendous risk factors and long-term health consequences for children. In recent decades, overwhelming studies have shown that periodontitis contributes to prematurity and LBW. This study was conducted to determine the link between maternal periodontitis and the pathogenesis of PTB and/or LBW through a rat infection model induced by Porphyromonas gingivalis, an important periodontopathic bacterium. The murine model was established by surgically ligating the left mandibular first molars and inoculating with P. gingivalis, and then all female rats initiated mating 6 weeks post infection. The gestational day and birth weight were recorded, and blood, amniotic fluid, and placental specimens were collected. Rats with a PTB and LBW newborns were observed in the P. gingivalis-infected group. Additionally, P. gingivalis infection significantly increased the maternal serum levels of interferon-γ and interleukin-1β, whereas no significant difference in the cytokine response was observed in the amniotic fluid. Moreover, with the translocation of P. gingivalis to placentas, remarkable changes in gestational tissues were found, followed by significantly enhanced expression of Toll-like receptor 2 (TLR2) as well as Fas and Fas ligand (FasL). These results support the concept that severe cases of periodontitis caused by P. gingivalis infection may be indicative of rats being more susceptible to PTB/LBW, probably through the activation of the TLR2 and Fas/FasL pathways within the placental tissues. This study gave us new insight into how maternal periodontopathogens might be linked to placental damage and premature pathogenesis.

Abstract
PURPOSE Discrepant results on relationship between chronic heart failure (CHF) and bone mineral density (BMD) have been reported and little has investigated the association between bone mass loss and New York Heart Association (NYHA) classification in CHF patients. This study aimed to assess whether BMD was associated with NYHA classification in older CHF patients. METHODS It was a retrospective study and included 1049 stable CHF patients aged over 60 years in Zhejiang Hospital. BMD and T-score at femoral neck (FN) and lumbar spines over L2-L4 regions were measured using Dual-Energy X-ray Absorptiometry. One-way ANOVA was used to compare continuous data of different NYHA functional class. Categorical variables were compared by Chi-square analysis. Pearson or Spearman correlation test was used to analyze the association between BMD and NYHA class, clinical parameters, lab data, etc. Significant variables in the correlation test (P < 0.05) were then tested by a multivariate linear regression test with stepwise subset selection to identify independent factors predicting BMD. RESULTS There were significant differences in FN BMD and T score across NYHA class I-IV, and that L2-L4 BMD and T score in patients in NYHA class IV were significantly lower when compared with CHF participants in NYHA classes I, II, and III. Moreover, Pearson correlation test and multivariate linear regression test demonstrated that there were statistically significant correlations between bone densitometric parameters and NYHA class. CONCLUSIONS There was a significant correlation between BMD and T-score at lumbar spines over L2-L4 and FN and NYHA class, implying that early screening and comprehensive intervention for osteoporosis (OP) might be helpful for patients with CHF.

Abstract
Senescence is a complex multiple factor proces, which is still poorly understood. The purpose of this study was to find the proteome of cultured human fetal lung diploid fibroblasts (2BS) of different population doubling (PD), as well as the altered proteome induced by salidroside (SAL) in 2BS cells. Proteins were identified by two-dimensional electrophoresis (2-DE) combining matrix-assisted laser desorption/ionization-time and flight mass spectrometry (MAL DI-TOF/MS). As a result, we found 16 proteins with two-fold variations in senescent cells or after SAL treatment, some being reduced such as reticulocalbin-1, heat shock protein beta-6, elongation factor 1-delta, F-actin-capping protein subunit alpha-1, and chloride intracellular channel 1. In contrast, 40S ribosomal protein SA, proteasome subunit alpha type-5, and zinc finger BED domain-containing protein 5 increased with cell age. Furthermore, heat shock protein beta-6, Zinc finger BED domain-containing protein 5 was increased in PD30 cells after 10 μM SAL treatment, whereas, elongation factor 1-delta, 6-phosphogluconolactonase, Nucleoside diphosphate kinase A, F-actin-capping protein subunit alpha-1, Probable ATP-dependent RNA helicase DDX41, Chloride intracellular channel 1, and Peroxiredoxin-6 were increased in PD50 cells after 10 μM SAL treatment. Some of these proteins were involved in the protein synthetic and degradative pathways, which emphasizes the metabolic disorder or functional impairment of cell senescence. Moreover, these proteins could be candidate biomarkers for evaluating the SAL anti-senescence effect.

Abstract
Objective This study aimed to verify the existing relationship between bone mineral density (BMD) and chronic heart failure (CHF) by meta-analysis. Methods Databases, including PubMed, Web of Science, and Chinese National Knowledge Infrastructure, published in English or Chinese up to February 28, 2017, were searched for studies on the association between CHF and BMD. Two independent reviewers collected the relevant articles. The standard mean deviation (SMD) and 95% confidence interval were calculated for BMD with fixed- and random-effect models. Subgroup and sensitivity analyses were also conducted. Results A total of six studies (552 CHF and 243 non-CHF patients) were included. The results indicated that the patients with CHF had a lower total BMD compared with the non-CHF patients. Similar effects were also observed for femoral neck, arm, leg, and trunk BMD. However, no difference was observed in the lumbar spine BMD. The SMD of total BMD in New York Heart Association classes I or II (NYHA I or II) patients was −0.62, while that in NYHA III or IV patients was −0.87, and the SMD of femoral bone mineral density in NYHA I or II patients was −0.47, while that in NYHA III or IV patients was −1.07. Moreover, vitamin D and parathyroid hormone (PTH) were also found to be associated with CHF. Conclusion Patients with CHF had a lower total BMD and femoral neck, arm, leg, or trochanter BMD than patients with non-CHF. Vitamin D reduced, whereas PTH increased, with the severity of CHF. The clinical significance of the present findings remains uncertain and should be confirmed by future studies.

Abstract
Objective: To investigate the feasibility of blood oxygen level-dependent MR (MR-BOLD) in assessing renal fibrosis of ureteral obstruction of rabbits. Methods: Forty healthy New Zealand rabbits were randomly divided into control group (n=8) and unilateral ureteral obstruction (UUO) group (n=32). The rabbits in the UUO group were subjected to unilateral ureteral obstruction of the left kidney.Coronal T(2) weighted imaging (T(2)WI) and axial BOLD examinations were performed before operation, 2, 4, 6 and 8 W after operation (each subgroup n=8). After the examinations, nephrectomy was performed for histologic evaluation.The T(2)(*) relaxation rate of the renal cortex (CR(2)(*)) , medulla (MR(2)(*)) and the same level of muscle(R(2)(*)(muscle)) were measured separately.The normalization of the cortex and medulla (sR(2)(*)), and the difference of sR(2)(*) between renal cortex and medulla before and post UUO (ΔsR(2)(*)) were calculated.The differences of sR(2)(*) (sCR(2)(*), sMR(2)(*), sCR(2)(*)(control), sMR(2)(*)(control)) at each time point between control and UUO group were compared by using independent sample t test.The LSD test was used to compare the sR(2)(*) in the control with that in the UUO group.The ΔsCR(2)(*) and ΔsMR(2)(*) values of the subgroups at UUO 2, 4, 6 and 8 W were compared by independent sample t test. Results: The sR(2)(*) values of UUO group were all lower than those of control group (all P<0.05), while sR(2)(*)(control) and sR(2)(*) in UUO group before operation were not significant different (P>0.05). The sCR(2)(*) values of UUO 2, 4, 6 and 8 W were 0.32±0.01, 0.37±0.01, 0.47±0.02 and 0.50±0.03.The sMR(2)(*) values were 0.39±0.02, 0.48±0.02, 0.58±0.04 and 0.65±0.05.There were significant differences of sCR(2)(*)(between) UUO 2 W and 6 W, UUO 2 W and 8 W, UUO 4 W and 6 W, UUO 4 W and 8 W (all P<0.01). There were significant differences of sMR(2)(*)(between) UUO 2 W and 6 W, UUO 2 W and 8 W, UUO 4 W and 8 W (all P<0.01). No significant difference was founded between sCR(2)(*) and sMR(2)(*) at each time point in control group (P>0.05). The ΔsCR(2)(*) values of UUO 2, 4, 6 and 8 W were 0.31±0.02, 0.20±0.02, 0.14±0.20, 0.09±0.04; the ΔsMR(2)(*) values were 0.51±0.05, 0.36±0.04, 0.28±0.05, 0.19±0.05. The ΔsCR(2)(*) values of UUO 2, 4 and 6 W were less than ΔsMR(2)(*) (P<0.05). There was no significant difference between ΔsCR(2)(*) and ΔsMR(2)(*) in UUO 8 W (P>0.05). Conclusions: The R(2)(*) change in medulla resulted from renal fibrosis is more significant than cortex.MR-BOLD can reflect the process of renal fibrosis.It's feasible and of great value to use renal MR-BOLD for the assessment of renal fibrosis induced by unilateral ureteral obstruction.

Abstract
Objective: To evaluate the feasibility of susceptibility weighted imaging (SWI) to reflect the progression of renal fibrosis (RF) induced by unilateral ureteral obstruction (UUO) in rabbits. Methods: Total of 32 New Zealand white rabbits (aged 4-5 months) were used to establish the UUO model (RF group) and were divided into 4 subgroups (including RF-2W group, RF-4W group , RF-6W group and RF-8W group) according to the duration of obstruction(2, 4, 6 and 8 weeks). Another 8 rabbits, underwent sham operation, were used as the control group (Sham group). T2 weighted imaging (T(2)WI) and SWI sequences were performed on the rabbits at 2, 4, 6 and 8 weeks after UUO, respectively. Rabbits were sacrificed and specimens were obtained after MR examination, then hematoxylin&eosin staining and Masson staining were performed to explore the renal tubular injury and interstitial fibrosis. The relationship between the relative signal-to-noise ratio(rSNR)measured on the SWI fusion maps and the degree of renal fibrosis was analyzed. Analysis of variance was used to compare the difference of rSNRs among 5 groups. Results: The rSNRs of the inner medulla gradually decreased over time, the rSNRs of Sham group, RF-2W group, RF-4W group, RF-6W group and RF-8W group was 2.29±0.18, 1.73±0.30, 1.67±0.08, 1.42±0.28, 1.12±0.15, respectively (F=25.876, P<0.01). In RF-2W group, the rSNRs of the outer medulla and cortex increased when compared with those in the Sham group, then they decreased gradually over time in the other groups (F=5.230, 7.621, both P<0.05). The pathological results demonstrated that the morphology of renal tubules in Sham group was normal and no apoptosis or necrosis was seen in the tubular epithelial cells. In the RF-2W group, the main pathological manifestations included renal tubules dilatation, tubular epithelial cell degeneration or necrosis and the infiltration of inflammatory cell. In Masson staining, lots of blue areas were present in the interstitial. As the obstruction time prolonged, the renal tubular collapse, inflammatory cells and fibroblasts increased significantly. Meanwhile blue area also increased significantly in Masson staining. Conclusion: SWI can be used as a noninvasive method to evaluate the pathological progression of fibrosis in the rabbit UUO model.
