Abstract
Objective: To explore the therapeutic efficacy and factors influencing the sequential combination of nucleos(t)ide analogues (NAs) with pegylated interferon alpha (Peg-IFN-α) in the treatment of patients with chronic hepatitis B (CHB). Methods: 144 CHB cases with NAs treatment for more than 1 year, HBV DNA < 20 IU/ml, hepatitis B surface antigen (HBsAg) quantification < 3 000 IU/ml, treated with a sequential combination of Peg-IFN-α treatment for 48 to 96 weeks, and followed up were selected from the Fifth Medical Center of the PLA General Hospital between May 2018 and May 2020. Intention-to-treat analysis was used to measure the HBsAg clearance rate at 96 weeks. The Kaplan-Meier method was used to compute the cumulative HBsAg clearance rate at 96 weeks. Univariate and multivariate logistic regression were used to analyze the factors influencing HBsAg clearance at 48 weeks of sequential combination therapy. Univariate and multifactorial COX proportional hazard models were used to analyze the factors influencing HBsAg clearance following 96 weeks of prolonged PEG-IFN-α treatment. The receiver operating characteristic curve was used to assess the predictive value of factors influencing HBsAg clearance. A Mann-Whitney U test was used to compare the measurement data between groups. The count data was compared using the χ(2) test between groups. Results: 41 (28.47%) cases achieved HBsAg clearance at 48 weeks of sequential combination therapy. The HBsAg clearance rate at 96 weeks was 40.28% (58/144) by intention-to-treat analysis. The Kaplan-Meier method computed that the cumulative HBsAg clearance rate at 96 weeks was 68.90%. Multivariate logistic regression analysis showed that HBsAg quantification at baseline (OR = 0.090, 95%CI: 0.034-0.240, P < 0.001) and a 24-week drop in HBsAg level (OR = 7.788, 95%CI: 3.408-17.798, P < 0.001) were independent predictors of HBsAg clearance in CHB patients treated sequentially in combination with NAs and Peg-IFN-α for 48 weeks. Receiver operating characteristic curve analysis showed that the baseline HBsAg quantification [area under the receiver operating characteristic curve (AUC), 0.911, 95% CI: 0.852-0.952)] and 24-week drop in HBsAg level (AUC = 0.881, 95%CI: 0.814-0.930) had equally good predictive value for 48-week HBsAg clearance, but there was no statistically significant difference between the two (Z = 0.638, P = 0.523). The value of the combination of baseline HBsAg quantification and 24-week drop in HBsAg level (AUC = 0.981, 95%CI: 0.941-0.997) was superior to that of single baseline HBsAg quantification (Z = 3.017, P = 0.003) and 24-week drop in HBsAg level (Z = 3.214, P = 0.001) in predicting HBsAg clearance rate at 48 weeks. Multivariate COX proportional hazards model analysis showed that HBsAg quantification at 48 weeks (HR = 0.364, 95%CI: 0.176-0.752, P = 0.006) was an independent predictor of HBsAg clearance with a prolonged course to 96 weeks of Peg-IFN-α treatment. Conclusion: The HBsAg clearance rate can be accurately predicted with baseline HBsAg quantification combined with a 24-week drop in HBsAg level in patients with CHB who are treated with a sequential combination of NAs and Peg-IFN-α therapy for 48 weeks. Prolonging the course of Peg-IFN-α treatment can enhance the HBsAg clearance rate's capability. An independent predictor of HBsAg clearance is HBsAg quantification at 48 weeks of sequential combination therapy with a prolonged course of 96 weeks of Peg-IFN-α treatment.

Abstract
Objective To evaluate the associations between serum uric acid (SUA) levels and estimated glomerular filtration rate (eGFR) and chronic kidney disease (CKD), with a focus on gender differences, and variations among women pre-and post-menopausal stages. Design A retrospective cohort study. Setting A large community-based survey was conducted every two years from 2010 to 2018 in Hangzhou, Zhejiang Province, Southeastern China. Participants 10,218 participants (40 years or above) without CKD at baseline who underwent three physical examinations were enrolled. CKD was defined as an eGFR of less than 60 mL/min/1.73m2. Methods Participants with SUA levels were divided into four groups (Q1-Q4) based on baseline SUA quartiles. The Q1 was the reference. By stratifying participants by gender, the relationships between SUA levels and eGFR were investigated using the generalized additive mixture model. The associations of SUA and the risk of incident CKD were examined using multivariate logistic regression models in the generalized estimating equation. Results After adjusting for confounding variables, a nonlinear association between SUA and eGFR was observed in females, while an approximately linear relationship was observed in males, suggesting that elevated SUA levels are associated with renal function decline. Furthermore, the highest quartile of SUA was associated with a 2.16-fold (95% CI: 1.31-3.58) increased risk of CKD in males and a 2.76-fold (95% CI: 1.59-4.78) increased risk in females, compared with the lowest quartile. And the spline curves demonstrated a U-shaped pattern, suggesting a potential threshold effect of SUA on the risk of CKD. Additionally, Subgroup analyses revealed significant associations between elevated SUA levels with CKD in postmenopausal women, but not in premenopausal women. Conclusion Elevated SUA levels are associated with an increased risk of CKD development and renal function decline in middle-aged and elderly individuals, particularly in postmenopausal women.

Abstract
BACKGROUND AND AIMS The beneficial effect of low-glycemic index (GI) diet on gestational diabetes mellitus (GDM) has been suggested in many observational studies; however, results from intervention trials remain inconsistent. This study aims to estimate the effect of interventions with low-GI dietary advice on pregnant outcomes in women with elevated risk of GDM. DESIGN PubMed, Web of Science, Embase, and Cochrane Library databases were searched for randomized clinical trials (RCTs) through March 2022. Studies reporting the effect of low-GI diet advice intervention on maternal and fetal outcomes in pregnant women with increased risks of GDM were included. Random or fixed effects model was used to calculate combined treatment effects. Publication bias was assessed via Begg's and Egger's tests and funnel plot inspection. RESULTS Nine RCTs recruiting 3416 participants were included. Low-GI diet advice did not modulate the risk of GDM. Compared with control diets, low-GI diet advice significantly reduced gestational weight gain (GWG) (weighted mean differences, WMD = -0.93 kg, 95% CI: -1.31, -0.55; p < 0.001; n = 7) and the risk of premature birth (RR = 0.55, 95% CI: 0.35, 0.88; p = 0.012; n = 5). In subgroup analyses, the effect of low-GI diet interventions on premature birth was significant only in women with BMI higher than 30 kg/m2 (RR = 0.28, 95% CI: 0.10, 0.77, p = 0.014; n = 3); the significant effect on GWG was not altered by stratification of BMI and the type of GDM risk factors. No significant changes in other maternal and newborn outcomes were found. CONCLUSIONS Low-GI diet advice interventions during pregnancy decreased GWG and the risk of premature birth in women with elevated GDM risk; however, the interventions did not significantly prevent GDM development in these women.

Abstract
OBJECTIVE To evaluate the associations between serum uric acid (SUA) levels and cardiovascular disease (CVD) risk factors, focusing on potential sex-specific differences. DESIGN A retrospective cohort study. SETTING A large community-based survey was conducted every two years from 2010 to 2018 in Hangzhou, Zhejiang Province, outheastern China. PARTICIPANTS 6119 participants aged 40 years and above who underwent at least three times of physical examinations were enrolled. METHODS Participants were categorised into four groups (Q1-Q4) based on baseline SUA quartiles within the normal range, with hyperuricaemia (HUA) as the fifth group. The Q1 was the reference. By stratifying participants by gender, the relationships between SUA levels and systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting blood glucose (FBG) and total cholesterol (TC) were investigated using linear regression models in the generalised estimating equation. Additionally, the associations of elevated SUA levels and HUA with hypertension, hyperglycaemia and dyslipidaemia were correspondingly examined using multivariate logistic regression models. RESULTS After adjusting for confounding variables, we found positive associations between SUA levels and SBP, DBP, FBG and TC in women, and with TC in men (p<0.01). Likewise, elevated SUA quartiles and HUA were linked to increased dyslipidaemia risk in both sexes, and increased hyperglycaemia risk only in women, with HRs (95% CI) of 1.64 (1.05 to 2.55) and 2.37 (1.47 to 3.81) in the Q4 and HUA group, respectively. Women with HUA had higher hypertension risk (HR=1.45, 95% CI 1.21 to 1.73), while no such association was observed in men. Stratified analyses revealed significant associations between elevated SUA levels and CVD risk factors in postmenopausal and non-obese women. CONCLUSIONS Elevated SUA levels increase the risk of dyslipidaemia in both sexes. SUA levels within normal range and HUA are positively associated with hyperglycaemia and hypertension in postmenopausal women, but not in men.

Abstract
The metabolite of organophosphate pesticide chlorpyrifos (CPF), 3,5,6-Trichloro-2-pyridinol (TCP), is persistent and mobile toxic substance in soil and water environments, exhibiting cytotoxic, genotoxic, and neurotoxic properties. However, little is known about its effects on the peripheral auditory system. Herein, we investigated the effects of TCP exposure on mouse postnatal day 3 (P3) cochlear culture and an auditory cell line HEI-OC1 to elucidate the underlying molecular mechanisms of ototoxicity. The damage of TCP to outer hair cells (OHC) and support cells (SC) was observed in a dose and time-dependent manner. OHC and SC were a significant loss from basal to apical turn of the cochlea under exposure over 800 μM TCP for 96 h. As TCP concentrations increased, cell viability was reduced whereas reactive oxygen species (ROS) generation, apoptotic cells, and the extent of DNA damage were increased, accordingly. TCP-induced phosphorylation of the p38 and JNK MAPK are the downstream effectors of ROS. The antioxidant agent, N-acetylcysteine (NAC), could reverse TCP-mediated intracellular ROS generation, inhibit the expressive level of cleaved-caspase 3 and block phosphorylation of p38/JNK. Overall, this is the first demonstration of TCP damaging to peripheral sensory HCs and SC in organotypic cultures from the postnatal cochlea. Data also showed that TCP exposure induced oxidase stress, cell apoptosis and DNA damage in the HEI-OC1 cells. These findings serve as an important reference for assessing the risk of TCP exposure.

Abstract
CONTEXT Resting heart rate (HR) is increasingly recognized as an indicator of disease and overall morbidity and mortality. Whether chronic coffee consumption affects resting HR is an important consideration for individual consumers as well as from a public health perspective. OBJECTIVE A meta-analysis of randomized controlled trials (RCTs) was conducted to examine the effectiveness of coffee consumption on resting HR. DATA SOURCES Original RCTs assessing the effect of coffee consumption on resting HR and published prior to March 2023 were identified by searching online databases, including PubMed, Web of Science, and Cochrane Library databases. DATA EXTRACTION AND ANALYSIS Data searches and extraction and risk-of-bias assessments were performed according to the Cochrane guidelines, and the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines for systematic reviews were followed. Data on study characteristics, type, and amount of coffee and net change and measurement resting HR were extracted. A random-effects or a fixed-effects model was used to estimate the pooled effect sizes. Homogeneity was determined with the Cochran Q test, and publication bias was assessed through Begg's test, Egger's test, and funnel plots. RESULTS A total of 6 RCTs with 11 intervention trials or arms involving 485 individuals were included. The participants were generally healthy, although some had hypertension, hypercholesterolemia, or were overweight. The trial duration ranged from 2 weeks to 24 weeks. The overall pooled analysis showed that coffee consumption resulted in a negligible increase in resting HR of 0.40 beats per minute (95% CI: -0.78 to 1.57; P = 0.506), which was statistically insignificant. Subgroup analysis of all specified categories was consistent with the overall analysis. No heterogeneity was observed among included trials (I2 = 0.0%, P = 0.756). CONCLUSION The results of the present meta-analysis study demonstrate that daily coffee consumption of 3 to 6 cups for a period of 2 to 24 weeks has no statistically significant effect on resting HR.

Abstract
Ferroptosis has been linked to the pathogenesis of hepatic injury induced by ischemia/reperfusion (I/R). However, the mechanistic basis remains unclear. In this study, by using a mouse model of hepatic I/R injury, it is observed that glutathione (GSH) and cysteine depletion are associated with deficiency of the reducing power of nicotinamide adenine dinucleotide phosphate (NADPH). Genes involved in maintaining NADPH homeostasis are screened, and it is identified that I/R-induced hepatic ferroptosis is significantly associated with reduced expression and activity of NADP+ -dependent malic enzyme 1 (Me1). Mice with hepatocyte-specific Me1 gene deletion exhibit aggravated ferroptosis and liver injury under I/R treatment; while supplementation with L-malate, the substrate of ME1, restores NADPH and GSH levels and eventually inhibits I/R-induced hepatic ferroptosis and injury. A mechanistic study further reveals that downregulation of hepatic Me1 expression is largely mediated by the phosphatase and tensin homologue (PTEN)-dependent suppression of the mechanistic target of rapamycin/sterol regulatory element-binding protein 1 (mTOR/SREBP1) signaling pathway in hepatic I/R model. Finally, PTEN inhibitor, mTOR activator, or SREBP1 over-expression all increase hepatic NADPH, block ferroptosis, and protect liver against I/R injury. Taken together, the findings suggest that targeting ME1 may provide new therapeutic opportunities for I/R injury and other ferroptosis-related hepatic conditions.

Abstract
Background Mental disorders account for an enormous global burden of disease, and has been associated with disturbed iron metabolism in observational studies. However, such associations are inconsistent and may be attributable to confounding from environmental factors. This study uses a two-sample Mendelian randomization (MR) analysis to investigate whether there is any causal effect of systemic iron status on risk of 24 specific mental disorders. Methods Genetic variants with concordant relations to 4 biomarkers of iron status (serum iron, ferritin, transferrin saturation, and transferrin) were obtained from a genome-wide association study performed by the Genetics of Iron Status (GIS) consortium. Summary-level data for mental disorders were obtained from the UK Biobank. An inverse-variance weighted (IVW) approach was used for the main analysis, and the simple median, weighted median and MR-Egger methods were used in sensitivity analyses. Results Genetically predicted serum iron, ferritin, and transferrin saturation were positively associated with depression and psychogenic disorder, and inversely associated with gender identity disorders. A higher transferrin, indicative of lower iron status, was also associated with increased risk of gender identity disorders and decreased risk of psychogenic disorder. Results were broadly consistent when using multiple sensitivity analyses to account for potential genetic pleiotropy. Conclusion Our findings offer a novel insight into mental health, highlighting a detrimental effect of higher iron status on depression and psychogenic disorder as well as a potential protective role on risk of gender identity disorders. Further studies regarding the underlying mechanisms are warranted for updating preventative strategies.

Abstract
Grandparenting is known to impact psychological health in older people. However, the extent to which the effect is altered by migration-related and sociodemographic determinants is less clear. Therefore, we conducted this cross-sectional study to investigate whether the association between grandparenting and psychological distress differs between rural-urban migrants and local older adults from May to September 2019. A total of 373 rural-urban migrants and 602 local older adults involved in grandparenting in Hangzhou completed measurements assessing sociodemographic characteristics, childcare burden and psychological distress. In total, 22.2% of the grandparents reported psychological distress. Rural-urban migrant grandparents had a lower socioeconomic status (SES), a higher childcare burden (23.6 ± 9.2 vs. 20.7 ± 9.5, p < 0.001) and higher levels of psychological distress (29.8% vs. 17.4%, p < 0.001) than local grandparents. Childcare burden and pressure from adult children were the most significant predictors for psychological distress in both groups (ps < 0.05). Psychological distress was also significantly associated with self-rated health status (β = -0.276, p = 0.033) and willingness to participate in grandparenting (β = -0.659, p = 0.024) in migrant grandparents but associated with female gender (β = 0.346, p = 0.022), caring for children at night (β = 0.424, p = 0.011), conflict with adult children (β = 0.432, p < 0.001) and annual income (β = -0.237, p < 0.001) in local grandparents. Migrant status showed a statistically significant moderating effect between childcare burden and psychological distress. These results may be of assistance in comprehensively understanding the social determinants of mental health of grandparents involved in grandparenting.

Abstract
Arsenic-based therapeutic strategies, even though promising for acute promyelocytic leukemia (APL), are limited by arsenic-related toxic effect and resistance with unknown mechanisms. The purpose of this study is to better understand the different sensitivities of hepatocellular carcinoma cells to arsenic and its mechanism. Arsenic-sensitive liver cancer cell line (HepG2) and arsenic-resistant HepG2 (AsHepG2) cells are employed to study the role of aquaporin 9 (AQP9) in arsenic uptake and tolerance. The half-maximal inhibitory concentration (IC50) value of arsenic in AsHepG2 cells (15.59 ± 1.36 µM) is significantly higher than that in HepG2 cells (7.33 ± 0.93 µM; p= 0.0288). We demonstrated that, with the treatment of sodium arsenite (NaAsO2), arsenic was accumulated at a significantly lower level in AsHepG2 cells in comparison with HepG2 cells (p= 0.00549). Further, arsenic level in AsHepG2 cells reaches a plateau after six hours of treatment, whereas arsenic continues to increase in HepG2 cells during the entire experimental period. Mechanistic study showed that the expression of AQP9 is decreased in a dose-dependent manner in AsHepG2 cells, but no significant difference in HepG2 cells. Furthermore, NaAsO2 dramatically increases AQP9 and p38 phosphorylation, which may partially regulate arsenic sensitivity in both cell lines. In conclusion, the expression and phosphorylation of AQP9 regulated by p38 kinase are involved in the arsenic uptake, thus regulating cellular arsenic sensitivity.

Abstract
OBJECTIVE To evaluation the dietary quality of Zhejiang population aged 40 years and older using the Dietary Balance Index(DBI) and to analyze the association between dietary quality and cognitive function. METHODS The dietary information was collected with the help of questionnaire survey, a 3-day dietary recall and household condiment weighing method from Zhejiang participants of the 2018 wave of the China Health and Nutrition Survey aged 40 years and older, and the food and energy intakes were calculated. The cognitive function was assessed by the Mini Mental Status Examination. Dietary quality was evaluated using the DBI method. A multivariate Logistic regression model was used to examine the association between dietary quality and the risk of cognitive impairment. RESULTS Among 640 participants aged 40 years and older, 14.2% had cognitive impairment. Univariate analysis showed that those with cognitive impairment had higher cereal(P=0.001), particularly, higher rice and products intake(P<0.001), as well as higher egg intake(P=0.008) than those with normal cognitive function; while the intake of soybean and its product(P=0.025) was lower. Those with cognitive impairment had higher DBI score of cereal(P=0.006) and high bound score(HBS)(P=0.028)than those with normal cognitive function. After adjustment for possible confounding factors, Logistic regression showed that moderated and severe over-consumption was positively associated with cognitive impairment(OR=2.486, 95% CI 1.130-5.470, P=0.024). CONCLUSION Over-consumption may increase the risk of cognitive impairment among aged Zhejiang population, and should be used to prevent or reduce cognitive decline by improving the quality of the diet through a reasonable dietary mix.

Abstract
Docosahexaenoic acid (DHA) and lutein are important nutrients for brain health. Whether there were synergistic effects of DHA and lutein on the protection against neuronal cell damage induced by oxidative stress remained unclear. The present study was designed to investigate the synergistic effects of DHA and lutein against hydrogen peroxide (H2O2)-induced oxidative challenge in PC12 cells. PC12 cells were divided into different groups and received H2O2 (80 μM), lutein (20 μM)+H2O2 (80 μM), DHA (25 μM)+H2O2 (80 μM), and lutein (20 μM)+DHA (25 μM)+H2O2 (80 μM), respectively. The results indicated that pre-treatment of cells with lutein, DHA and DHA+lutein could significantly antagonize the H2O2-mediated growth inhibition and morphological changes in PC12 cells (p<0.05). Molecularlevel studies indicated that the DHA+lutein combination can significantly inhibit the mRNA expression of AMAD10 and BAX. Furthermore, Western blot analysis demonstrated that DHA+lutein synergistically inhibits the phosphorylation of JNK1/2. The results of the present study suggest that DHA and lutein in combination may be utilized as potent antioxidative compounds, with potential preventative or palliative effects on age-related neurodegenerative diseases.

Abstract
OBJECTIVES As the global aging phenomenon intensifies, the incidence of Alzheimer's disease (AD) is gradually increasing. Diet appears to be an effective way to prevent and delay the progression of AD. Previous studies have found that cognitive impairment and neuronal damage were effectively alleviated by blueberry extract (BBE) in AD mice, but its mechanism is still unclear. The aims of this study were to detect the main anthocyanins of BBE; then to verify the protective effects of anthocyanin-rich BBE on hippocampal neurons and the promotion of autophagy; and finally to investigate the main protective effects and mechanisms of protocatechuic acid (PCA), a major metabolite of BBE, for promoting autophagy and thus playing a neuroprotective role. METHODS APP/PS1 mice were given 150 mg/kg BBE daily for 16 wk. Morphology of neurons was observed and autophagy-related proteins were detected. RESULTS Neuron damage in morphology was reduced and the expression of autophagy-related proteins in APP/PS1 mice were promoted after BBE treatment. In vitro, Aβ25-35-induced cytotoxicity, including decreased neuron viability and increased levels of lactate dehydrogenase and reactive oxygen species, was effectively reversed by PCA. Furthermore, by adding autophagy inducers rapamycin and autophagy inhibitors Bafilomycin A1, it was verified that degradation of autophagosomes was upregulated and autophagy was promoted by PCA. CONCLUSION This study elucidated the mechanism of BBE for reducing neuronal damage by promoting neuronal autophagy and proved PCA may be the main bioactive metabolite of BBE for neuroprotective effects, providing a basis for dietary intervention in AD.

Abstract
In observational studies of children and adolescents, higher body weight has been associated with distinct disease outcomes, including cancer, in adulthood. Therefore, we performed a two-sample Mendelian randomization (MR) study to evaluate the causal effect of childhood obesity on long-term cancer risk. Single-nucleotide polymorphisms associated with higher childhood body mass index (BMI) from large-scale genome-wide association studies were used as genetic instruments. Summary-level data for 24 site-specific cancers were obtained from UK Biobank. We found that a 1-SD increase in childhood BMI (kg/m2 ) was significantly associated with a 60% increase in risk of pancreatic cancer (odds ratio [OR]: 1.60; 95% confidence interval [CI]: 1.12-2.28; P < 0.01) and a 47% increase in risk of esophageal cancer (OR: 1.47; 95% CI: 1.09-1.97; P < 0.01) in adults. In contrast, there was an inverse association of genetic predisposition to childhood obesity with throat (OR: 0.46; 95% CI: 0.27-0.79; P < 0.01) and breast cancer (OR: 0.77; 95% CI: 0.64-0.94; P < 0.01) in adult life. For the other 20 cancers studied, no statistically significant association was observed. Our MR analyses found causal effects of childhood obesity on several cancers. Maintaining a healthy weight should be emphasized during childhood and adolescence to prevent cancer risk later in life.

Abstract
BACKGROUND & AIMS Gestational Diabetes Mellitus (GDM) is associated with a well-documented range of adverse pregnancy outcomes. The present meta-analysis was conducted to evaluate the effects of vitamin D supplementation on glycemic control and maternal-neonatal outcomes in women with established GDM. METHODS Published literature was retrieved and screened from PubMed, Embase, Web of Science, CNKI (China National Knowledge Infrastructure), Wanfang, and Cochrane Center Register of Controlled Trails up to May 2020. RCTs of vitamin D supplementation on pregnant women with GDM were included. RESULTS 19 RCTs (1550 participants) were eligible for meta-analyses. Overall, vitamin D supplementation significantly reduced serum fasting plasma glucose (FPG) (MD: -10.20 mg/dL, 95%CI: -13.43 to -6.96), insulin concentration (MD: -5.02 μIU/mL, 95%CI: -6.83 to -3.20) and the homeostasis model assessment of insulin resistance (HOMA-IR) (MD:-1.06, 95%CI: -1.40 to -0.72) in women with GDM. In addition, vitamin D supplementation in pregnant women with GDM significantly reduced adverse maternal outcomes including cesarean section (RR: 0.75, 95%CI: 0.63 to 0.89), maternal hospitalization (RR: 0.13, 95%CI: 0.02 to 0.98) and postpartum hemorrhage (RR: 0.47, 95%CI: 0.22 to 1.00). Several adverse neonatal complications including neonatal hyperbilirubinemia (RR: 0.47, 95%CI: 0.33 to 0.67), giant children (RR: 0.58, 95%CI: 0.38 to 0.89), polyhydramnios (RR: 0.42, 95% CI: 0.24 to 0.72), fetal distress (RR: 0.46, 95%CI: 0.24 to 0.90) and premature delivery (RR: 0.43, 95% CI: 0.26 to 0.72) were also significantly reduced. CONCLUSIONS This meta-analysis suggested that supplementation of GDM women with vitamin D may lead to an improvement in glycemic control and reduction of adverse maternal-neonatal outcomes.

Abstract
OBJECTIVE To determine the risk factors of the occurrence of nonsyndromic cleft lip and/or cleft palate (NSCL/P) in Xinjiang Province, China. DESIGN The study included 359 patients of NSCL/P and 310 controls. Information about sociodemographic characteristics, lifestyle behaviors, negative life events, possible environmental hazards exposures, and use of supplementations were collected from cases and controls. Both t test and χ2 tests were used for group comparisons. Multivariable logistic regression was used to estimate the independent associations between environmental risk factors and the presence of NSCL/P. The receiver operating characteristic curve was used to establish the predictive variables for the occurrence of NSCL/P. RESULTS The results showed that maternal pesticide exposure (odds ratio [OR] = 11.40, 95%CI: 5.40-24.10), antibiotic drugs use (OR = 1.32, 95%CI: 1.14-1.53), paternal smoking (OR = 3.30, 95%CI: 1.87-5.83), threatened abortion (OR = 12.2, 95%CI: 3.29-45.25) were associated with increased risk of NSCL/P in offspring. In contrast, maternal moderate (OR = 0.43, 95%CI: 0.20-0.92) and middle physical workload (OR = 0.48, 95%CI: 0.0.23-0.97), vitamin-B complex supplementations (OR = 0.11, 95%CI: 0.03-0.41), calcium and iron (OR = 0.27, 95%CI: 0.08-0.90) supplementations were associated with reduced risk of NSCL/P in offspring. These variables together explain nearly 60% of the variation of occurrence of NSCL/P. CONCLUSION These findings from our study may help to develop primary prevention strategies for NSCL/P in Xinjiang.

Abstract
Background:Many of the rheumatic and musculoskeletal diseases (RMD) are long term, painful, and function affecting, which takes both the doctors and patients a lot of time and effort. The number of Rheumatologists are not sufficient for the huge population of RMD patients in China. The doctor patient ratio is as low as 1:1000. Relatively inadequate medical resources, traffic inconvenience in rural area, and patients’ insufficient understandings of the RMD may cause delayed medical intervention and poor prognosis. Effective RMD patient management tools which provide disease monitoring and enough doctor-patient communication is essential to improve the patients’ adherence to treatment. We designed an RMD management app according to the social, cultural and economic situation of Chinese patients, which helps to facilitate shared decision making and relieve the pressure of insufficient medical resources.Objectives:We aim to investigate the effect of RMD patient management app on treat-to-target therapy and patients’ adherence and satisfaction to treatment.Methods:An observational survey was administrated using a RMD patient management app. The app was designed and improved by Rheumatologist, orthopedics, nurses, patients, and app technical experts. Patients were offered with a questionnaire in regard to satisfaction with the app and their attitudes about the disease. General therapeutic principles, rehabilitation exercise videos and follow-up information were distributed through the app. Warning signals were sent whenever there was a flag sign of exacerbation. The demographic and clinical data, social and economic status, and drug retention rates of the patients were documented. The survey was designed by clinical experts from relevant departments and developed by both doctors and patients.Results:All patients were supervised by the rheumatologist and orthopedist when using the app. In all the patients included, there were cases of rheumatoid arthritis (35.3%), osteoarthritis (32.4%), ankylosing spondylitis (26.5%), and other chronic arthritis (5.8%). The mean age 38.5±15.8 years old, with 52.9% male and 47.1% female. Most of the patients (85.3%) believed that the app was helpful. Young patients were more likely to respond to the survey than older patients. Some patients (79.4%) had increased compliance because the app offered more chances to communicate with the doctors, which increase their understanding and confidence about the disease. Three patients received flag signs of exacerbation much earlier than they could get to the hospital. From the feedback of the patients, we realized that the patient would like to have more information to keep them from stepping on the trap of false advertisement for therapy (which is very commonly seen in China).Conclusion:RMD patient need to manage disease activity, daily function and mental state. Insufficient medical resources and patients’ knowledge about the disease may lead to poor adherence and prognosis. RMD patient management tool on app was a feasible and cost-effective approach for data collection and patient education. The app increased treat-to-target therapy and patients’ adherence to treatment.References:None.Disclosure of Interests:None declared

Abstract
OBJECTIVE To evaluate the safety and efficacy of allogeneic natural killer (NK) cells in the treatment of primary hepatocellular carcinoma (HCC), and to elucidate the mechanism of NK cells therapy. METHODS Twenty-one patients with primary HCC treated with allogeneic NK cells at the Fifth Medical Center of the PLA General Hospital were followed up for 1 year. Peripheral blood mononuclear cells (PBMCs) were isolated from patient-related donors and cultured in vitro for 15 days and infused to the patients in two consecutive days. Clinical data and laboratory data were collected and analyzed, including survival, clinical features, imaging changes, hematology, immunology, and biochemical indicators to evaluate the safety and efficacy of allogeneic NK cell therapy. The changes of peripheral blood lymphocyte subsets after treatment were also analyzed to explore the possible anti-tumor mechanisms. RESULTS (1) Of the 21 patients with primary HCC, 11 patients were treated once, 5 patients were treated twice, and 5 patients were treated 3 times. After allogeneic NK cells infusion, 10 patients had fever, 1 patient had slight hepatalgia and 1 patient had slight headache, no other adverse events occurred including acute and chronic graft-versus-host disease (GVHD). They resolved spontaneously within 8 hours without other treatment. (2) The total disease control rate was 76.2% during one-year follow-up. Among them, the patients with Barcelona clinic liver cancer (BCLC) stage A had a disease control rate of 100%, stable disease (SD) in 10 cases; BCLC stage B patients had a disease control rate of 60%, partial response (PR) in 1 case, and SD 2 in cases; BCLC stage C patients had a disease control rate of 50%, complete response (CR) in 1 case, and 2 cases of PR. (3) The frequencies of NK cells and CD8+ T cells in peripheral blood were significantly lower than that before at 24 hours after treatment, and the frequencies of CD4+ T cells and CD4/CD8 were significantly higher than the baseline. CONCLUSION Allogeneic NK cells have good safety and efficacy in the treatment of primary HCC. The anti-tumor effect of the allogeneic NK cells may play an important role in the activation of the patient's natural immune system and delay disease progression, suggesting that allogeneic NK cells combined with sorafenib may be a very effective treatment for advanced HCC, and further large-sample multicenter randomized controlled clinical trials are needed to validate this result.

Abstract
BACKGROUND AND OBJECTIVES β-Carotene-15,15'-oxygenase (BCO1) is a key enzyme involved in carotenoid metabolism and has been linked with the development of coronary atherosclerosis. This study investigated the association between BCO1 polymorphisms and the risk of coronary atherosclerosis in dyslipidemia participants, and analyzed the influence of personal behaviors on coronary atherosclerosis. METHODS AND STUDY DESIGN A nested case-control study was conducted from 2013 to 2016 in which 1359 dyslipidemia participants were recruited. Personal lifestyle parameters, mainly physical activities and diet, were obtained by questionnaires and the genotypes of rs11641677, rs11646692, rs12934922, rs6564851 and rs7501331 in BCO1 were analyzed by ligase detection reaction. In 2016, 166 participants were diagnosed with coronary atherosclerosis and 498 age-and gendermatched controls were recruited. The association between BCO1 polymorphisms and risk of coronary atherosclerosis were analyzed with logistic regression, and the effect of gene-behaviors interaction on the risk of coronary atherosclerosis were determined with crossover analysis. RESULTS After adjustment for potential confounders, logistic regression analysis showed that fried food intake (OR=1.637, 95% CI: 1.127~2.378; p=0.010), dessert intake (OR=1.733, 95% CI: 1.158~2.595; p=0.008), and physical activity (OR=0.511, 95% CI: 0.309~0.846; p=0.009) were risk factors for coronary atherosclerosis. Rs12934922 and rs11646692 reflected high susceptibility to coronary atherosclerosis. Crossover analysis indicated that rs12934922 and rs11646692 interacted with physical activity (Inter-OR=8.82; Inter-OR=3.69), fried food intake (Inter-OR=2.95; Inter-OR=2.36) and dessert intake (Inter-OR=3.95; Inter-OR=2.39) to influence the risk of coronary atherosclerosis. CONCLUSIONS In dyslipidemia patients, rs12934922 and rs11646692 may influence the development of coronary atherosclerosis. A combination of BCO1 polymorphisms and several behavioral factors may affect the development of coronary atherosclerosis.

Abstract
Objective: To investigate the clinicpathologic features and probable mechanisms of massive subcortical heterotopia. Methods: Clinical data, histologic features and neuropathologic data were analyzed in five cases of massive subcortical heterotopia collected from Xuanwu Hospital, Capital Medical University from January 2014 to October 2017. Results: All five patients (three males and two females) had a history of refractory epilepsy with a mean period of 15.4 years (range 7 to 21 years). The median age at surgery was 28.6 years(range 20 to 39 years). Magnetic resonance imaging showed that the lesions were located in the temporal lobe (two cases), parietal lobe (one case), both temporal and occipital lobes (one case) and both temporal and parietal lobes (one case). Pathologic examination disclosed that massive gray matter in subcortical and deep white matter with various shape and size. Moreover, one case also showed subpial and periventricular heterotopias and polymicrogyria. Polymicrogyria or hippocampal sclerosis were seen in the remaining three cases. None of the five patients experienced seizure attacks during the follow-up period. Conclusions: Heterotopia is malformations due to abnormal neuronal migration. Massive subcortical heterotopia due to widespread abnormal neuronal migration is relatively rare. The mechanism of heterotopia together with polymicrogyria needs further discussion.

Abstract
BACKGROUND Both aldehyde dehydrogenase 2 (ALDH2) rs671 polymorphism and lifestyle behaviors are involved in coronary artery disease (CAD), while the interaction between them is currently unknown. METHODS A nested case-control study was conducted in 161 patients with CAD and 495 controls in dyslipidemia population in Yinzhou District, Ningbo, Zhejiang Province, China, in August 2013. Anthropometric data and blood samples were collected, demographic characteristics and lifestyle behaviors information were obtained by a face-to-face interview, dietary intake was assessed by a food frequency questionnaire, and genomic DNA was genotyped. RESULTS Carriers with increasing number of A alleles had an elevated CAD risk compared with G allele carriers (adjusted OR = 1.483, 95% CI = 1.114-1.974). Carriers of rs671 A/G and A/A genotypes had a higher CAD risk than carriers of G/G genotype (adjusted OR = 1.492, 95% CI = 1.036-2.148). Similarly, individuals with rs671 A/A genotype had a higher CAD risk than individuals with A/G and G/G genotypes (adjusted OR = 2.161, 95% CI = 1.139-4.101). We found a borderline additive interaction between regular fried food intake and A/A and A/G genotypes, and a significantly additive interaction between sedentary/light physical activity and A/A and A/G genotypes. CONCLUSIONS Individuals with A/A or A/G genotypes of rs671 have a higher CAD risk, if they lack physical activity and take fried food regularly, than individuals with G/G genotypes. These findings can help to provide a guide to targeted heart health management.

Abstract
Background and objective Several studies have been conducted to examine the association between aldehyde dehydrogenase 2 family (ALDH2) rs671 polymorphism and essential hypertension (EH). However, the results remain inconsistent. This study aimed to clarify the association between ALDH2 rs671 polymorphism and EH susceptibility. Methods One thousand and ninety-four cases and 1236 controls who were ethnic Han Chinese were collected for this population-based case-control study. A meta-analysis was performed to calculate the pooled odds ratio and 95% confidence interval, using allele contrast, dominant, recessive, and co-dominant models using fixed or random-effect models. Results Significant differences were observed between EH cases and controls at the level of both genotype (χ2 = 6.656, P<0.05) and alleles (χ2 = 6.314, P<0.05). An additional meta-analysis using 4204 cases and 5435 controls established that rs671 was significantly associated with EH (P<0.00001). Conclusion The results of our case-control study and meta-analysis showed that there is a significant association between ALDH2 rs671 polymorphism and EH susceptibility. In addition, the results of the breakdown analysis by gender suggest a male-specific association between the ALDH2 rs671 polymorphism and EH.

Abstract
OBJECTIVES Peripheral leucocyte telomere length has been suggested to be inversely associated with hypertension risk. Both telomere length and hypertension risk can be modified by certain dietary factors, such as fruit and vegetables. This study was to examine the potential effect of these dietary factors on the association between telomere length and hypertension risk. STUDY DESIGN A community-based case-control study. PARTICIPANTS 271 hypertensive patients and 455 normotensive controls aged 40-70 years and living in Yinzhou, Zhejiang Province, China. OUTCOME MEASURES Peripheral leucocyte relative telomere length (RTL) was measured using quantitative real-time PCR. Dietary intake was assessed by a brief semiquantitative food frequency questionnaire. The association between RTL and hypertension risk was analysed using logistic regression, and the modulatory effect of dietary intake on RTL-related hypertension risk was analysed using likelihood ratio tests. RESULTS Among controls, longer age-adjusted RTL was associated with higher vegetable intake (p=0.01). Individuals with longer age-adjusted RTL (based on median value) were 30% less likely to have hypertension (OR=0.70, 95% CI 0.52 to 0.96; p=0.03). The observed RTL-hypertension relationship appeared to be modified by vegetable intake-longer RTL was significantly associated with lower hypertension risk only in those with greater vegetable consumption (OR=0.28, 95% CI 0.14 to 0.57; p<0.001), but not in those with lower vegetable intake (P-interaction=0.008). CONCLUSIONS Certain dietary factors might modify telomere-related hypertension risk.

Abstract
Insulin and IGFs play a significant role in cancer development and progression, including renal cell carcinoma (RCC). RCC is the most frequent type of kidney cancer in adults and the tenth most common malignancy worldwide. Insulin is normally associated with metabolism control, whereas IGFs are defined as proliferation regulators. Today, there is convincing evidence of an association between obesity and the risk of RCC. Indicated risk factors together with type 2 diabetes are irreversibly connected with circulating insulin and IGF levels. The interplay between these molecules, their receptors, and IGF-binding proteins might be crucial for RCC cell biology and RCC progression. Given the potent activity IGF/IGF receptor 1 (IGF1R) inhibitors demonstrate against RCC in basic research, some type of combination therapy may prove to be beneficial clinically in the management of RCC. This review addresses not only molecular but also clinical associations between insulin and IGF1 signaling pathways and both RCC biology and clinical course. Revealing these interactions may improve our understanding of basic molecular oncology processes in RCC and improve treatment strategies.

Abstract
Background Kaposi’s sarcoma (KS)-associated herpesvirus (KSHV) is the etiologic agent of KS, the most common AIDS-related malignancy. The majority of KS tumor cells harbor latent KSHV virus but only a small percentage undergoes spontaneous lytic replication. Viral reactivation from latency is crucial for the pathogenesis and development of KS, but the cellular mechanisms underlying the switch between viral latency and replication are not well understood. Methods The level of let-7 miRNAs and MAP4K4 in KSHV infected 293T cells were quantified by real-time PCRs. Let-7 expression was silenced by the miRNA sponge technique. In let-7a transfected 293T cells, the expression of MAP4K4 was measured by real-time PCR and western blot. Luciferease expression was employed to examine the effect of let-7a on the 3’-untranslated region (UTR) of the MAP4K4 gene in 293T cells. Real-time PCR was used to quantify the KSHV copy numbers in BC-3 cells in which the expression of let-7a and/or MAP4K4 were altered. Finally, ERK, JNK and p38 protein production and their phosphorylation status were detected by western blots in let-7a or MAP4K4 transfected BCBL-1 cells. Results The expression of microRNA let-7 was dramatically decreased in KSHV infected 293T cells, but that of MAP4K4 was increased significantly. Let-7a is physically associated with and targets the MAP4K4 3’UTR, and inhibits MAP4K4 expression at both mRNA and protein levels. MAP4K4 stimulates KSHV reactivation from latency, whereas let-7a inhibits the function of MAP4K4 by reversing the function of MAP4K4 on JNK, phospho-JNK and phospho-ERK1/2 levels. Conclusion Our results establish that let-7a specifically suppresses MAP4K4 expression, and further inhibits KSHV reactivation by interfering with the function of MAP4K4 on the MAPK pathway, highlighting let-7a as a potential treatment for KS.

Abstract
AIM To investigate the role of Cytochrome P4502E1 in sensitizing Kupffer cells to lipopolysaccharide (LPS)-mediated inflammation after ethanol induction. METHODS Sprague-Dawley rats were fed a liquid ethanol diet, control diet or ethanol diet supplemented with CYP2E1 inhibitor, chlormethiazole (CMZ), for 4 weeks. Hepatic CYP2E1 protein, nuclear factor-kappa B (NF-κB) p65 protein and tumor necrosis factor (TNF)-α mRNA were measured. In vitro, isolated Kupffer cells from control rats were exposed to ethanol with different CMZ concentration; CYP2E1 expression and reactive oxygen species (ROS) generation were compared. The identified CMZ concentration was further utilized to evaluate the role of CYP2E1 on the sensitization of ethanol-induced Kupffer cell to LPS. The effect of LPS alone was tested in controlled Kupffer cells without ethanol. TNF-α, nuclear NF-κB p65 and cytoplasm IκB-α were monitored for all groups. RESULTS Ethanol feeding increased hepatic CYP2E1 level, nuclear accumulation of NF-κB p65 and TNF-α expression in rats. These changes were inhibited by CMZ supplementation. In cultured Kupffer cells, increased CYP2E1 content and ROS production by in vitro ethanol induction were dose-dependently inhibited by CMZ. Compared with LPS alone, the ethanol induction group produced significantly more TNF-α, nuclear NF-κB p65 and less cytoplasm IκB-α under LPS stimuli. CMZ abolished the effects of ethanol on LPS-stimulated NF-κB translocation and TNF-α generation in Kupffer cells. CONCLUSION In cultured Kupffer cell, using CMZ as inhibitor, ethanol-induced CYP2E1 overexpression was proved to contribute to the sensitization of Kupffer cells to LPS stimuli, with amplification of ROS production and activation of NF-κB, resulting in increased TNF-α production.

Abstract
Chronic alcohol ingestion increases hepatic cytochrome P450 2E1 (CYP2E1), which is associated with hepatocarcinogenesis. We investigated whether treatment with chlormethiazole (CMZ), a CYP2E1 inhibitor, protects against alcohol-associated hepatic carcinogenesis in rats. Rats were fed either an ethanol liquid diet or a non-ethanol liquid diet, with or without CMZ for one and ten months. A single intraperitoneal injection of diethylnitrosamine (DEN, 20 mg/kg) was given to initiate hepatic carcinogenesis. CYP2E1 expression, inflammatory proteins, cell proliferation, protein-bound 4-HNE, etheno-DNA adducts, 8-hydroxy-2'-deoxyguanosine (8-OHdG), retinoid concentrations, and hepatic carcinogenesis were examined. Ethanol feeding for 1 month with DEN resulted in significantly increased hepatic CYP2E1 levels and increased nuclear accumulation of NF-κB protein and TNF-α expression, which were associated with increased cyclin D1 expression and p-GST positive altered hepatic foci. All of these changes induced by ethanol feeding were significantly inhibited by the one month CMZ treatment. At 10-months of treatment, hepatocellular adenomas were detected in ethanol-fed rats only, but neither in control rats nor in animals receiving ethanol and CMZ. The 8-OHdG formation was found to be significantly increased in ethanol fed animals and normalized with CMZ treatment. In addition, alcohol-reduced hepatic retinol and retinoic acid concentrations were restored by CMZ treatment to normal levels in the rats at 10 months of treatment. These data demonstrate that the inhibition of ethanol-induced CYP2E1 as a key pathogenic factor can counteract the tumor-promoting action of ethanol by decreasing TNF-α expression, NF-κB activation, and oxidative DNA damage as well as restoring normal hepatic levels of retinoic acid in DEN-treated rats.

Abstract
Lycopene has been shown to be beneficial in protecting against high-fat diet-induced fatty liver. The recent demonstration that lycopene can be converted by carotene 9',10'-oxygenase into a biologically active metabolite, ALA, led us to propose that the function of lycopene can be mediated by ALA. In the present study, male ob/ob mice were fed a liquid high-fat diet (60% energy from fat) with ALA supplementation (ALA group, 240 μg · kg body weight(-1) · d(-1)) or without ALA supplementation as the control (C group) for 16 wk. Steatosis, SIRT1 expression and activity, genes involved in lipid metabolism, and ALA concentrations in the livers of mice were examined. The results showed that ALA supplementation resulted in a significant accumulation of ALA in the liver and markedly decreased the steatosis in the ALA group without altering body and liver weights compared to the C group. The mRNA and protein levels of hepatic SIRT1 were higher in the ALA group compared to the C group. SIRT1 activity also was higher in the ALA group, as indicated by the lower levels of acetylated forkhead box class O1 protein levels. In addition, the mRNA level of acetyl CoA carboxylase 1 was significantly lower in the ALA group than in the C group. Because SIRT1 plays a key role in lipid homeostasis, the present study suggests that the lycopene metabolite, ALA, protects against the development of steatosis in ob/ob mice by upregulating SIRT1 gene expression and activity.

Abstract
Chronic and excessive alcohol consumption has been related to an increased risk of several cancers, including that of the liver; however, studies in animal models have yet to conclusively determine whether ethanol acts as a tumor promoter in hepatic tumorigenesis. We examined whether prolonged alcohol consumption could act as a hepatic tumor promoter after initiation by diethylnitrosamine (DEN) in a rat model. Male Sprague-Dawley rats were injected with 20 mg DEN/kg body weight 1 wk before introduction of either an ethanol liquid diet or an isoenergic control liquid diet. Hepatic pathological lesions, hepatocyte proliferation, apoptosis, PPARα and PPARγ, and plasma insulin-like growth factor 1 (IGF-1) levels were assessed after 6 and 10 mo. Mean body and liver weights, plasma IGF-1 concentration, hepatic expressions of proliferating cellular nuclear antigen and Ki-67, and cyclin D1 in ethanol-fed rats were all significantly lower after 10 mo of treatment compared with control rats. In addition, levels of hepatic PPARγ protein, not PPARα, were significantly higher in the ethanol-fed rats after prolonged treatment. Although ethanol feeding also resulted in significantly fewer altered hepatic foci, hepatocellular adenoma was detected in ethanol-fed rats at 10 mo, but not in control rats given the same dose of DEN. Together, these results indicate that chronic, excessive ethanol consumption impairs normal hepatocyte proliferation, which is associated with reduced IGF-1 levels, but promotes hepatic carcinogenesis.

Abstract
BACKGROUND Vitamin D deficiency has been associated with markers for allergy and asthma severity in children with asthma. However, its association with Chinese adult asthmatics has not been studied. OBJECTIVE To examine whether vitamin D status is associated with lung function and total serum IgE in Chinese adults with newly diagnosed asthma. METHODS We conducted a cross-sectional study including 435 Chinese patients aged >18 years with newly diagnosed asthma. Vitamin D status was assessed by measuring serum 25 hydroxyvitamin D (25OHD) concentrations. The primary outcomes included airflow limitation, as measured by the forced expiratory volume in 1 s (FEV(1)), FEV(1) % predicted, and FEV(1)/forced vital capacity (FVC), and serum total IgE concentration. RESULTS Vitamin D deficiency was prevalent in Chinese adults with asthma, with 88.9% of the subjects having 25OHD <50 nmol/l. Serum 25OHD concentration was positively correlated with FEV(1) % predicted (p = 0.02, r = 0.12). After adjusting for age, sex, body mass index, smoking, month of blood collection, and symptom duration, we found significant positive associations between 25OHD concentrations and FEV(1) (in liters), FEV(1) % predicted, and FEV(1)/FVC (p for trend < 0.05 for all). The adjusted odds ratios for the highest versus the lowest 25OHD quartile were 0.50 (0.26-0.96) for FEV(1) <75% predicted and 0.44 (0.20-0.95) for FEV(1)/FVC% <0.75. There was no significant association between 25OHD concentrations and total IgE. CONCLUSIONS Vitamin D deficiency was highly prevalent in Chinese asthma patients, and vitamin D status was associated with lung function.

Abstract
Enhancement of multiple heavy metal uptake from municipal solid waste (MSW) compost by Lolium perenne L. in a field experiment was investigated with application of EDTA. EDTA was added in solution at six rates (0-30 mmol kg( - 1)) after 50 days of plant growth. Two weeks later, plants were harvested for the first crop and then all the turfgrasses were mowed. After another 30 days of growth, EDTA was added again at above six rates to the corresponding sites and the second crop was harvested 2 weeks later. The results showed that EDTA significantly increased heavy metal accumulation in both crops of L. perenne. For the first crop, the concentrations of Mn, Ni, Cd, and Pb in the shoots increased remarkably with increasing EDTA supply, peaked at 25 mmol kg( - 1) EDTA, and shoots of 0-5 cm height (shoots from medium surface to 5 cm height) had higher metal concentrations than 5-10 cm and >10 cm shoots. The highest concentration of Mn, Ni, Cd, and Pb was 2.3-, 2.3-, 2.6-, and 3.2-fold, respectively, in 0-5 cm shoots higher than control. For the second crop, the concentrations of Mn, Cu, and Pb in shoots were, in general, less than those in the first crop. However, the second crop was significantly higher (P < 0.05) than the first crop in dry biomass, so the total amount of metals removed by the second crop was more than the first crop. In addition, EDTA significantly increased the translocation ratios of most heavy metals from roots to shoots. For the first crop, 38% of the total Zn, 51% of Cd, 49% of Pb, 60% Mn, 55% Ni, and 45% Cu taken up by the plant was translocated in the shoots of 0-5 cm height. Turfgrass would have potential for use in remediation of heavy metals in MSW compost or contaminated soils.

Abstract
Abstract
Chronic and excessive alcohol ingestion, a known risk factor of liver cancer, has been shown to upregulate hepatic cytochrome P450 2E1 (CYP2E1), which is associated with the production of reactive oxygen species and carcinogenic acetaldehyde, the activation of procarcinogens as well as the enhanced catabolism of retinoid. Further, treatment with the CYP2E1 inhibitors, including chlormethiazole (CMZ), have been shown to protect against alcohol-induced liver injury. In order to determine whether treatment with CYP2E1 inhibitor protects against diethylnitrosamine (DEN)-initiated, alcohol-promoted carcinogenesis in the liver, we fed rats (n=6) with either an ethanol liquid diet (Lieber-DeCarli diet) or a non-ethanol liquid diet with isocaloric maltodextrin, with or without CMZ (100 mg/kg BW), for a short-term (1 month) and a long-term (10 months). DEN was given as an initiator for hepatic carcinogenesis by i.p. injection of 20 mg DEN/kg BW. Hepatocarcinogenesis was assessed by examining the placental glutathione-s-transferase (p-GST) immunostaining of altered hepatic foci (AHF) and hepatic tumors lesions. Hepatocyte proliferation was assessed by immunohistochemistry for proliferating cellular nuclear antigen and Ki67, as well as cyclin D1. Hepatic expression of TNF-α and activation of NF-κB and CYP2E1 were assessed by either RT-PCR or Western blotting analysis. Hepatic retinol and retinoic acid were analyzed by reverse-phase HPLC. Results showed that CMZ treatment significantly inhibited ethanol-induced AHF formation, CYP2E1 expression and activity, TNF-α mRNA expression, NF-κB activation and hepatocyte proliferation after a 1-month period. After 10-months of treatment, hepatic nodular regenerative hyperplasia, and hepatocellular adenoma and carcinoma were detected in the ethanol-fed rats, but not in the rest of rat groups with the same dose of DEN treatment, including non-ethanol fed rats and ethanol-fed rats with CMZ treatment. In addition, the CMZ treatment prevented alcohol-reduced retinol and retinoic acid in the livers of rats after 1- and 10-months of treatment. These data demonstrate that CYP2E1 inhibitor can counter the tumor-promoting action of ethanol by restoring normal hepatic levels of retinoic acid. In considering the efficacy and complex biological functions of retinoids in human cancer prevention, intervention using CYP2E1 inhibitors that target alcohol-induced CYP2E1, could provide complementary or synergistic protective effects against alcohol-related cancer risk.

Abstract
High intake of fish oil with a low omega-6 (n-6)/omega-3 (n-3) polyunsaturated fatty acid (PUFA) ratio has been suggested to protect against many chronic diseases. However, the effect of different ratios of dietary n-6 and n-3 PUFA on lung tumorigenesis has not been investigated. In this study, we examined the effect of a 4 mo dietary supplementation with corn oil (with a high n-6/n-3 ratio) and fish oil (with a low n-6/n-3 ratio) as compared with soybean oil (isocaloric control with the same n-6/n-3 ratio as the base diet) on tumor incidence and tumor prevalence in the A/J mouse model of 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK)-induced lung carcinogenesis. We found that dietary supplementation had no effect on overall lung tumor incidence, but fish oil supplementation was able to decrease lung tumor prevalence by 78% and 80% compared to groups receiving soybean oil and corn oil supplementation, respectively. The inhibitory effect of fish oil on lung tumor prevalence was associated with increased expressions of cell cycle inhibitor p21Cip1 and lipoxygenase isoform 15-LOX in the lungs. These data suggest that fish oil with a low ratio of n-6/n-3 PUFA could be beneficial in the prevention of lung carcinogenesis.
