Abstract
Abstract
Background
Implementation of evidence-based medicine requires minimising delays between data generation and guideline creation. We examined the temporal relationship between accumulating evidence from randomized controlled trials (RCTs) of blood pressure (BP) lowering drug therapy among individuals with SBP<140 mmHg, DBP<90 mmHg, or both, and hypertension guideline recommendations over time.
Methods
A systematic review was conducted by searching MEDLINE for RCTs between January 1966 and February 2018. Included trials randomized patients to BP lowering drug(s) vs placebo/no treatment or to more vs less BP lowering with at least 1000 patient-years of follow-up per treatment group, and provided data relevant to BP lowering in patients with SBP<140 mmHg, DBP<90 mmHg, or both (hereafter <140/90 mmHg). Included trials were classified according to major patient groups and whether all patients had baseline BP <140/90 mmHg, or most control group patients had BP <140/90 mmHg during follow-up, which was selected because this is the BP against which interventions were compared. Two reviewers independently extracted relevant data from included RCTs and hypertension guidelines. Cumulative meta-analyses of cardiovascular events were conducted and were compared to hypertension guideline recommendations. The primary outcome was major cardiovascular events.
Results
A total of 73 trials (n=300,805) were included, including 16 trials/subgroups with all participants baseline BP <140/90mmHg. Benefits of BP lowering in individuals with usual BP <140/90 mmHg began to emerge in the 1970s (Figure). Most evidence was from trials that included some or all patients with hypertension at baseline, but most patients had BP <140/90 mmHg during follow-up due to regression to the mean and background treatment. Starting from 1992, 22 trials reported results by baseline hypertension status with no difference in cardiovascular event relative risk reduction among those with and without hypertension (relative risk 0.87 [95% CI 0.84–0.90] vs 0.86 [0.83–0.90], respectively. Until 2017, no major guidelines recommended treatment initiation or intensification for patients with baseline BP <140/90 mmHg, apart from the periods during which some guidelines recommended treatment at lower thresholds for patients with diabetes and chronic kidney disease (Joint National Committee 1997 to 2014; European Society of Hypertension 2007 to 2009).
Cumulative meta-analyses of trials
Conclusions
Evidence of benefits of BP lowering among individuals with usual BP <140/90 mmHg have been demonstrated for decades. However, there has been a substantial delay between data generation and guideline recommendations. This delay was may be due to the inappropriate emphasis on baseline rather than usual BP levels, and relatively narrow evidence synthesis, which does not fully account for evidence generated across various major patient groups.

Abstract
Graphene derivatives are the new bioactive material with good physical and chemical properties and excellent biocompatibility. It has been found that graphene derivatives can improve the mechanical properties of biomaterials and promote the adhesion, proliferation and differentiation of osteoblast-related cells, so as to promote implant-bone bonding and repair of bone defects. This makes it a research hotpot in the field of bone tissue regeneration. In this paper, the mechanism of graphene derivatives promoting bone regeneration and their application in the oral field were reviewed, so as to provide theoretical basis for their application in basic and clinical research.

Abstract
Abstract
BACKGROUND
Gliomas comprise heterogeneous malignant glial and stromal cells. While blood vessel co-option is a potential mechanism to escape anti-angiogenic therapy, the relevance of glial phenotype in this process is unclear.
MATERIAL AND METHODS
Here, we intravitally study preclinical syngenetic models of glioma as well as patient-derived cells transplanted orthotopically. Moreover, we profoundly confirm our preclinical results with histological studies on patient specimens.
RESULTS
We show that Olig2+ oligodendrocyte precursor-like glioma cells invade by single-cell vessel co-option and preserve the blood-brain barrier (BBB). Conversely, Olig2-negative glioma cells form dense perivascular collections and promote angiogenesis and BBB breakdown, leading to innate immune cell activation. Experimentally, Olig2 promotes Wnt7b expression, a finding that correlates in human glioma profiling. Targeted Wnt7a/7b deletion or pharmacologic Wnt inhibition blocks Olig2+ glioma single-cell vessel co-option and enhances responses to temozolomide. Finally, Olig2 and Wnt7 become upregulated after anti-VEGF treatment in preclinical models and patients.
CONCLUSION
Here, we show that glioma is able to employ vessel co-option, i.e. the movement of tumor cells towards and along the pre-existing vasculature.
Glioma oligodendrocyte-like (OPCL) cells express Wnt7 that is necessary for vessel co-option and Wnt inhibitors significantly improve survival with temozolomide. Moreover, we demonstrated that anti-VEGF-treatment of glioma selects for Olig2/Wnt7+ cells

Abstract
BACKGROUND No previous study has focused on the inter-relationship among alcohol and drug use variables in the past year. This study aimed to classify the past year alcohol and drug use variables and investigate the selected variables in past year alcohol and drug use with the unmet need for mental health services among US adults. METHODS Data came from the 2015 National Survey on Drug Use and Health (NSDUH). Oblique principal component cluster analysis (OPCCA) was used to classify 37 variables on alcohol and drug use in the past year into disjoint clusters. Weighted multiple logistic regression analysis was used to examine the associations of selected variables with the unmet need. RESULTS 37 alcohol and drug use variables were divided into 7 clusters. The variable with the lowest 1-R2 ratio (R2 is the squared correlation) from each cluster was selected as follows: tobacco use, pain reliever use, tranquilizer use, stimulant use, zolpidem products use, illicit drug and alcohol use, and benzodiazepine tranquilizers misuse. Multiple logistic regression analysis showed that pain reliever use (OR = 1.33, 95% CI = 1.17-1.50), tranquilizer use (OR = 2.49, 95% CI = 2.16-2.86), stimulant use (OR = 1.22, 95% CI = 1.01-1.47), and illicit drug and alcohol use (OR = 1.54, 95% CI = 1.34-1.77) revealed positive associations with the unmet need for mental health services. CONCLUSION This is the first study using OPCCA to reduce the dominations of alcohol and drug use; several alcohol and drug use variables in the past year were associated with unmet need of mental health services.

Abstract
Objective: To explore the effects of oxidative stress on renal dopamine D(1) receptor dysfunction in offspring of diabetic rat dams. Methods: The pregnant Sprague Dawley (SD) rats (n=10) were randomly divided into the diabetic group (a single intraperitoneal injection of 35 mg/kg streptozotocin on day 0 of gestation) and control group (injected with the equal volume of 0.9% saline on day 0 of gestation) according to the random number table (n=5 each group). The offspring rats were divided into 4 groups including offspring of control dams treated with vehicle, offspring of control dams treated with antioxidant, offspring of diabetic dams treated with vehicle and offspring of diabetic dams treated with antioxidant (n=10 each group). After birth, the offspring rats were treated with normal drinking water or antioxidant (tempol, 1.0 mmol/L) from the age of 4 weeks until the end of the study (20 weeks). The blood pressure was monitored continuously by non-invasive tail-cuff method. The renal oxidative markers including superoxide dismutase (SOD) and malondialdehyde (MDA) activity and D(1) receptor agonist (fenoldopam)-mediated urinary and sodium excretion were detected. Furthermore, the protein expression of renal G protein-coupled receptor kinase 2 (GRK2), GRK4, dopamine D(1) receptor and the phosphorylation level of D(1) receptor were detected. Results: The mean arterial pressure of offspring from the diabetic dams treated with vehicle was significantly higher than that of offspring from control dams treated with vehicle (P=0.013), while the mean arterial pressure of offspring from diabetic dams treated with antioxidant was significantly lower than that of offspring from the diabetic dams treated with vehicle (P=0.038). The fenoldopam-mediated urinary flow and urinary sodium excretion rate were significantly lower in offspring of diabetic dams treated with vehicle than those in offspring of control dams treated with vehicle (P<0.01), which were significantly higher in offspring of diabetic dams treated with antioxidant as compared to offspring of diabetic dams treated with vehicle (both P<0.01). There was no significant difference in fenoldopam-mediated urinary flow and urinary sodium excretion rate in offspring of control dams treated with antioxidant or vehicle (urinary flow: P=0.772; urinary sodium excretion rate: P=0.716). Compared with offspring of control dams treated with vehicle, the renal MDA activity was significantly increased, while the SOD activity was significantly decreased in offspring of diabetic dams treated with vehicle (MDA: P<0.01; SOD: P=0.013). The renal MDA activity was significantly decreased, while the SOD activity was significantly increased in offspring of diabetic dams treated with antioxidant in comparison with offspring of diabetic dams treated with vehicle (MDA: P<0.01; SOD: P=0.035).The renal GRK2 and GRK4 protein expression in offspring of diabetic dams treated with vehicle were significantly higher than those in offspring of control dams treated with vehicle (P<0.01), while the expression levels of renal GRK2 and GRK4 in offspring of diabetic dams treated with antioxidant were significantly downregulated compared with offspring of diabetic dams treated with vehicle (P<0.01). There was no significant difference in the protein expression of dopamine D(1) receptor among 4 groups (P=0.735). The level of dopamine D(1) receptor phosphorylation in offspring of diabetic dams treated with vehicle was significantly higher than that in offspring of control dams treated with vehicle (P<0.01), while the dopamine D(1) receptor phosphorylation level was significantly lower in offspring of diabetic dams treated with antioxidant compared to that in offspring of diabetic dams treated with vehicle (P<0.01). Conclusion: Oxidative stress is involved in the dopamine D(1) receptors dysfunction in the offspring of diabetic dams.

Abstract
Objective: To observe the position of the electrode in the cochlea following cochlear implantation by cone beam computed tomography (CBCT). Methods: Twenty-five children who received cochlear implantation and CBCT examinations in the Department of Otorhinolaryngology Head and Neck Surgery from the Second Hospital of Shandong University between January 2016 and December 2017 were selected. There were 15 males (17 ears) and 10 females (10 ears). The age ranged from 0.5 to 7.0 years old, with a median age of 1.6 years. 23 patients with unilateral implantation and two patients with bilateral implantation. The implants were all Med-El standard 12-electrode contact arrays. The CBCT was used to determine the position of the electrode in the cochlea, the distance between the electrode contacts and modiolus, and intracochlear insertion length of the electrode arrays. SPSS Statistics, version 22.0 was used for data processing and statistical analysis. Results: CBCT images could clearly demonstrate the structure of round window, oval window, modiolus, osseous cochlear duct, osseous spiral lamina, and electrodes. The electrode arrays of all the children were fully implanted into the cochlea. 26 of the electrode arrays were located in the scala tympani and one of them was inserted into the scala vestibular. The mean intracochlear insertion length of the electrode arrays was 30.23 (95%CI, 30.04-30.71) mm. The distance between the electrode contacts and modiolus gradually increased at the 1-4th electrode contacts and reached the maximum at the 4th electrode contacts with an average of 1.10 mm (95%CI, 1.02 to 1.18 mm), and then gradually decreased from the 5th electrode contacts. Conclusions: CBCT can clearly show cochlear fine structures and therefore accurately assess the electrode position following cochlear implantation.

Abstract
Objective: To explore the therapeutic efficacy of nasal Continuous Positive Airway Pressure (CPAP) and aerobic exercise of different intensity in patients with Obstructive Sleep Apnea Hypopnea Syndrome (OSAHS) and Type 2 Diabetes Mellitus (T2DM). Methods: A total of 112 patients with OSAHS and T2DM, including 53 males and 59 females, with a mean age of (66.9±7.8) years old, from the Fourth Rehabilitation Hospital of Shanghai and the Second Affiliated Hospital of Soochow University from January 2017 to December 2018 were enrolled prospectively. There were divided into two groups based on whether received nasal CPAP therapy: 50 cases in nasal CPAP+aerobic exercise group and 62 cases in aerobic exercise group. Subsequently, patients in nasal CPAP+aerobic exercise group were randomly divided into two subgroups: moderate and low intensity aerobic exercise (26 and 24 cases respectively). All patients completed nasal CPAP and (or) aerobic exercise of different intensity for 20 weeks. The therapeutic efficacy of polysomnography (PSG) parameters, glycolipid metabolism, 6 minutes walking distance (6 MWD), and rate of perceived exertion (RPE) were compared between each group before and after treatment. Results: Pre-and post-intervention, PSG parameters, body mass index (BMI) [(26.6±3.7) vs (24.3±2.8) kg/m(2)], RPE [(16.4±1.3) vs (12.2±2.6) score], 6 MWD [(372.6±59.7) vs (441.5±75.6) m] and glucolipid metabolism indexes were improved significantly in nasal CPAP+aerobic exercise group (all P<0.05), such as fasting blood glucose [(7.4±2.4) vs (6.2±1.6) mmol/L], glycosylated hemoglobin [(7.6±1.2)% vs (6.6±0.7)%], fasting insulin [(10.8±4.4) vs (6.9±3.4) μU/L], insulin resistance index [(3.5±1.9) vs (1.9±1.2)], total cholesterol [(4.0±0.9) vs (3.5±0.9) mmol/L], low density lipoprotein cholesterol [(4.2±0.6) vs (3.1±0.8) mmol/L]; BMI, exercise endurance, some glucolipid metabolism indexes and PSG parameters were also improved in aerobic exercise group (P<0.05). After 20 weeks' intervention, it showed statistically significant differences in PSG parameters, glycometabolism, some lipid metabolism indexes and RPE (all P<0.05), and no significantly difference in BMI [(24.3±2.7) vs (24.3±2.8) kg/m(2)] between the two groups. Compared with the low intensity subgroup, there were significant improvement in 2 hours' postprandial insulin, insulin resistance index, low density lipoprotein cholesterol, lipoprotein A, RPE, 6 MWD in moderate subgroup (P<0.05). Conclusion: Nasal CPAP combined with moderate intensity aerobic exercise can effectively improve the glucolipid metabolism, insulin resistance and exercise tolerance in patients with OSAHS and T2DM.

Abstract
Objective: To assess the prevalence and related factors of HIV infection among male clients of the female sex workers in Hekou Yao autonomous county of Honghe Hani Yi autonomous prefecture (Hekou county) in Yunnan province in China, 2014-2015. Methods: Serial cross-sectional survey was conducted during June 2014 to November 2015. Convenience sampling methods were used to recruit the male clients for this study. Self-reported information on social-demographic characteristics, with sexual and drug behavior patterns, was gathered. Both blood and urine samples were collected for HIV, with for opiate testing. Multivariate logistic regression and Exhaustive CHAID method were used to determine the correlated factors associated with HIV infection. Statistical analysis was used by SPSS 22.0 software and Clementine 12.0 software. Results: The overall HIV prevalence of male clients was 2.06% (16/776). Male clients who keep using condom with female sex worker was estimated as 68.81% (534/776). The last commercial sexual partner of Vietnamese male clients was all Vietnamese female sex workers. Compared with Chinese male clients, Vietnamese male clients have a higher rate of morphine positive. Factors as: age ≥50 years vs. age <30 years (OR=8.11, 95%CI: 1.26-52.16) and testing for morphine positive vs. morphine negative (OR=7.35, 95%CI: 1.42-38.06) were significantly associated with HIV infection through multiple logistic regression analysis. Through Exhaustive CHAID, it confirmed that age was the primary factor that associated with HIV infection of male clients. Conclusions: Relationship between morphine and HIV infection indicated that HIV prevalence of male clients in Hekou county was influenced by the combined effect of both illegal drug use and commercial sexual behavior. Special attention should be paid to male clients over 50 years of age, on HIV intervention.

Abstract
Objective: To investigate the dose-response relationship between hemoglobin concentration and preterm birth, during pregnancy. Methods: With Zhuang ethnicity, a total of 12 780 pregnant women and their infants that admitted to Wuming、Pingguo、Jingxi、Debao、Longan and Tiandong hospitals, were recruited, in Guangxi Zhuang Autonomous Region, from January 2015 to December 2017. Non-conditional logistic regression method was used to analyze the effect of anemia on preterm birth during pregnancy. Dose-response relationship between hemoglobin concentration and preterm birth was explored, using the restrictive cubic spline model. Results: After excluding 2 053 pregnant women with hypertension or aged 35 years and over, results from the non-conditional logistic regression analysis showed that the risk of preterm birth in the anemia group was 1.29 times (OR=1.29, 95%CI: 1.04-1.59, P=0.019) of the non-anemia group in the first trimester. Data from the restricted cubic sample showed that there appeared nonlinear "L" dose-response relationship between hemoglobin concentration and preterm birth in the first trimester and "U" shape in the third trimester (non-linearity test P<0.001). Conclusion: There appeared nonlinear dose-response relationship between the hemoglobin concentration and preterm birth, both in the first and third trimesters.

Abstract
Objective: To understand the characteristics and causes of pesticide poisoning in Xuzhou city, and provide basis for formulating prevention and control measures. Methods: The cases of pesticide poisoning in Xuzhou City from 2005 to 2017 were collected from "Pesticide Poisoning Report Card" . The data were analyzed and assessed by EpiData. The SPSS 22.0 software was used for statistical analysis. Results: During the thirteen years, there were a total of 8092 cases of pesticide poisoning, among which, the number of occupational pesticide poisoning was 1 408, accounting for 17.4% of the total number of cases, 14 patients died, the case fatality rate was 0.1%. There were 2, 992 cases of male poisoning, accounting for 36.97% of the total number of cases, and 5, 100 cases of female poisoning, accounting for 63.03%. There were 6684 non-productive pesticide poisonings, accounting for 82.6% of the total number of cases; 387 deaths occurred, and the mortality rate was 5.8%. Among non-productive poisonings, the incidence of oral pesticide poisoning was 84.3%, and the incidence of accidental poisoning by pesticides was 15.7%. Organophosphorus pesticides poisoning cases accounted for the majority of oral pesticide poisoning cases. The overall incidence of pesticide poisoning showed a downward trend. The age of non-productive pesticide poisoning cases was mainly 15-44 years old, and the number of cases of poisoning were 4 029 cases (60.28%) . With the increase of age, the mortality rate of poisoning cases was higher, especially for those over 60 years old who died of oral pesticide poisoning (40.1%) . The peak of pesticide poisoning began to increase in the second quarter and reached its peak in the third quarter. Conclusion: Although the cases of pesticide poisoning reported in Xuzhou City have been declining in recent years, the situation is still severe. The proportion of oral pesticide suicide accounts for a large proportion, and the mortality rate of elderly and female is relatively high, and the government should pay more attention. Workers should conduct safety education and psychological counseling to improve the knowledge and consciousness of safe use of pesticides.

Abstract
AIMS/OBJECTIVES To investigate the underlying molecular mechanism of the patient's ABO typing discrepancy. BACKGROUND ABO typing discrepancy was frequently seen in patients due to different causes. In this study, ABO typing discrepancy was found in a 24-year-old man with arthralgia, whose forward ABO grouping was O and reverse ABO grouping was AB. Primary immunodeficiency disease was speculated in this patient, especially X-linked agammaglobulinemia (XLA). METHODS Immunoglobulins of all isotypes were detected using a specific protein analyser. Lymphocyte subgroups were analysed by flow cytometry. All 19 exons and boundaries of BTK gene were amplified by polymerase chain reaction (PCR), and all PCR products were sequenced by a DNA analyser. BTK protein in the leukocytes and platelets was detected by Western blot. RESULTS No B lymphocytes could be detected in the peripheral blood of the patient. A novel BTK gene variation, c.817G>T, in the exon 9 of BTK gene was discovered. No BTK protein expression could be detected in the leukocytes and platelets of the patient. CONCLUSIONS XLA could be occasionally discovered by ABO typing discrepancy in some cases because of the deficiency of reciprocal IgM anti-A and/or anti-B antibodies in the serum of the patient. Humoral immunodeficiency is one of the causes of ABO typing discrepancy.

Abstract
Objective: To determine the association of serum fibroblast growth factor-23 concentrations with age-related cardiac diastolic function subclinical state and whether this association differs by sex. Methods: Seven hundred sixteen healthy subjects (aged 35-89 years, 68.4% female) were selected from National Basic Research Program of China (973 Program-China Medical University subsection) between January 2014 and February 2015 and assigned into 4 groups according to sex and age:< 60 years old male and female group, ≥ 60 years old male and female group. Blood biochemical indicators and general clinical data of the subjects were measured. The glomerular filtration rate (eGFR) were estimated using the Modified Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI-ASIA) equation. The fibroblast factor 23 (FGF-23), C-reactive protein (CRP) and interleukin-6 (IL-6) were measured by enzyme-linked immunosorbent assay (ELISA). Cardiac structure and function parameters including left atrial diameter (LAD), inter-ventricular septum thickness (IVST), left ventricle posterior wall thickness (LVPWT), left ventricle mass index (LVMI),left atrial mass index (LAVI) and the ratio of peak velocity of early filling to the septal early peak diastolic mitral annulus velocity(E/e') were measured by echocardiography. Association between serum FGF-23 and aging-related diastolic function subclinical status was analyzed by binary Logistic regression analysis. Results: (1) Serum log-transformed FGF-23 levels were significantly higher in males than in females [(2.0±0.3) ng/L vs (1.9±0.4) ng/L, P<0.05]. (2) Cardiac diastolic function gradually decreased with age, and age related cardiac diastolic function decline of female was significantly higher than males[E/e':<60 years old male group (7.6±2.6), ≥ 60 years old male group (8.6±2.7), P<0.01;<60 years old female group (8.3±2.3), ≥ 60 years old female group (9.5±3.1), P<0.01; LAVI:<60 years old female group (14±5) ml/m(2), ≥ 60 years old female group (16±5) ml/m(2), P<0.01]. (3) Serum FGF-23 was significantly positively correlated with age (r=0.089, P<0.05) and LAVI (r=0.084, P<0.05) in total study population while with E/e' (r=0.149, P<0.05) only in males. There was no significant correlation between serum FGF-23 and cardiac diastolic function parameters in females. (4) Binary Logistic regression analysis showed that median and high FGF-23 were independently associated with age-related cardiac diastolic function decline (OR=2.831, 95% CI: 1.144-7.009, P=0.024; OR=2.548, 95% CI: 1.053-6.163, P=0.038) in males. Conclusions: Serum FGF-23 concentrations are associated with age-related cardiac diastolic function subclinical state in a healthy Chinese population. High levels of FGF-23 are independently associated with age-related cardiac diastolic function decline in males.

Abstract
OBJECTIVE This study was designed to investigate the impact of astrocyte and lymphocyte (LC) interactions in the blood-brain barrier (BBB) on the pathogenesis of multiple sclerosis (MS). METHODS Primary rat brain microvascular endothelial cells (rBMECs) and astrocytes isolated from Sprague-Dawley rats were used to establish in vitro BBB models. Transendothelial electrical resistance (TEER) and permeability were compared between rBMEC monocultures and rBMEC/astrocyte co-cultures to evaluate the validity of each as a BBB cell model. rBMEC/LC co-cultures and rBMEC/astrocyte/LC tri-cultures were established to evaluate inflammatory responses in MS by measuring the gene expression levels of nerve growth factor (NGF), matrix metalloproteinase 2 (MMP-2), matrix metalloproteinase 9 (MMP-9), interleukin 17 (IL-17), interferon γ (IFN-γ), and forkhead box P3 (Foxp3). RESULTS The rBMEC/astrocyte co-cultures exhibited higher TEER values and lower lymphocyte permeabilities than those of rBMEC monocultures. Compared to the rBMEC mono-cultures, the rBMEC/astrocyte/LC tri-cultures showed significantly decreased NGF, IL-17, and IFN-γ and increased MMP-2 and Foxp3 expression. Furthermore, the tri-cultures exhibited decreased NGF, IL-17, and IFN-γ expression compared to the rBMEC/astrocyte co-cultures, and increased MMP-2 expression compared to that shown by the rBMEC/LC co-cultures. MMP-9 expression did not vary significantly between the four established BBB cell models. CONCLUSION These results suggest that the synergistic effect between astrocytes and LCs may increase the expression of MMP-2 and decrease that of IL-17 and IFN-γ at the BBB. Furthermore, the use of rBMEC/astrocytes/LC tri-cultures enabled us to test the synergistic effect between astrocytes and LCs and their roles in MS pathogenesis.

Abstract
AIM Fasting serum C-peptide is a biomarker of insulin production and insulin resistance, but its association with vascular complications in type 2 diabetes mellitus (T2DM) has never been fully elucidated. This study aimed to investigate whether C-peptide is associated with cardiovascular disease (CVD) and diabetic retinopathy (DR). METHODS A total of 4793 diabetes patients were enrolled from seven communities in Shanghai, China, in 2018. CVD was defined as a self-reported combination of previous diagnoses, including coronary heart disease, myocardial infarction and stroke. DR was examined using fundus photographs. Logistic regression analyses were performed, and multiple imputed data were used to obtain stabilized estimates. RESULTS Prevalence of CVD increased with increasing C-peptide levels (Q1, Q2, Q3 and Q4: 33%, 34%, 37% and 44%, respectively; Pfor trend < 0.001), whereas DR prevalence decreased with increasing C-peptide quartiles (Q1, Q2, Q3 and Q4: 21%, 19%, 15% and 12%, respectively; Pfor trend < 0.001). On logistic regression analysis, C-peptide levels were significantly associated with CVD prevalence (1.27, 95% CI: 1.13-1.42; P < 0.001) and C-peptide quartiles (Q1: reference; Q2: 1.31, 95% CI: 1.00-1.70; Q3: 1.53, 95% CI: 1.16-2.01; Q4: 1.76, 95% CI: 1.32-2.34; Pfor trend < 0.001). Given the interaction between C-peptide and BMI and the association between C-peptide and CVD (Pfor interaction = 0.015), study participants were divided into two subgroups based on BMI which revealed that the association persisted despite different BMI statuses. However, DR prevalence decreased with increasing C-peptide levels (0.73, 95% CI: 0.62-0.86; P < 0.001) and quartiles (Q1: reference; Q2: 1.00, 95% CI: 0.76-1.33; Q3: 0.69, 95% CI: 0.50-0.94; Q4: 0.51, 95% CI: 0.36-0.72; Pfor trend < 0.001). CONCLUSION C-peptide was positively associated with CVD, but inversely associated with DR progression. The association between C-peptide and CVD could be due to associated metabolic risk factors.

Abstract
OBJECTIVE To estimate the prevalence of mental health service use among US adults, examine the associations of mental health service use with health insurance coverage, mental health problems and drug use, and detect health disparities. METHODS This was a cross-sectional study with 5,434 adults receiving mental health service out of 37,424 adult respondents from the 2013 National Survey on Drug Use and Health. Weighted univariate and multiple logistic regression analyses were used to estimate the associations of potential factors with mental health service use. RESULTS The overall prevalence of mental health services use was 14.7%. Our results showed that being female, aging, having a major depressive episode, serious psychological distress, and illicit drug or alcohol abuse/dependence were positively associated with mental health service use; whereas being African American, Asian or Hispanic ethnicity, married, and having any form of insurance were negatively associated with mental health service use . Stratified analysis by insurance types showed that Medicaid/CHIP, CHAMPUS, and other insurance were positively associated with mental health service use. CONCLUSIONS Health insurance coverage, mental health problems, and drug abuse or dependence were associated with mental health service use in US adults. Furthermore, adults with different insurances had disparities in access of mental health service.

Abstract
Objectives: To investigate the association between the dynamics of thyroid volume and the changes of physical growth in school-aged children as well as to compare the applicability of different thyroid volume indexes, so as to explore more reliable methods for the assessment of thyroid volume. Methods: In October 2012, a multi-stage cluster sampling method was used to select a primary school in Minhang district of Shanghai, Haimen city of Jiangsu province and Yuhuan city of Zhejiang province, respectively. In these areas, a total number of 784 students aged 8-10 years were enrolled in the cohort. Demographic data was collected, while height and weight were measured, with BMI and body surface area (BSA) were calculated. Thyroid volume was examined by B-ultrasonography. Height volume index (HVI), weight and height volume index (WHVI), BMI volume index (BMIV) and BSA volume index (BSAV) were all applied to correct the thyroid volume. All students were followed up, one year later. Results: A total of 769 students with complete data on thyroid volume and physical growth were enrolled, including 378 boys (49.16%) and 391 girls (50.84%). Thyroid volume showed an increase with age, while growth of thyroid volume reduced with the increase of age (P<0.001). The thyroid volume showed a correlation with the changes of physical growth. The growth of height appeared as the dominant influencing factor for thyroid volume growth in those aged 8 and 10 years (P<0.05), while the growth of weight, BMI and BSA were all influencing factors for thyroid volume on students aged 9 years (P<0.05). Conclusions: Thyroid volume in school-aged children was a factor not only associated with age but also with physical growth which had not been considered in the currently used criteria. The inclusion of items as iodine intake, age, physical growth into the thyroid volume indexes seemed to be more reliable, in practice. For the assessment of goiter, HVI for students aged 8 and 10 years and BMIV for students aged 9 years might serve as better indicators.

Abstract
Objective: To understand the survival status and influencing factors for HIV/AIDS patients on highly active anti-retroviral therapy (HAART) in Shandong province. Methods: Both Kaplan-Meier (K-M) method and cumulative incidence function (CIF) were used to calculate the cumulative incidence of AIDS-related death respectively, and Fine-Gray model was used to identify the influencing factors related to survival time. Results: Through K-M method, a higher AIDS-related cumulated death rate than the CIF, was estimated. Among all the HIV/AIDS patients who initiated HAART from 2003 to 2015 in Shandong, 5 593 of them met the inclusion criteria. The cumulative incidence rate for AIDS-related death was 3.08% in 1 year, 4.21% in 3 years, 5.37% in 5 years, and 7.59% in 10 years respectively by CIF. Results from the F-G analysis showed that HIV/AIDS patients who were on HAART, the ones who had college degree or above (HR=0.40, 95%CI: 0.24-0.65) were less likely to die of AIDS-associated diseases. However, HIV/AIDS patients who were on HAART and living in the western areas of Shandong (HR=1.33, 95%CI: 1.01-1.89), diagnosed by medical institutions (HR=1.39, 95%CI: 1.06-1.80), started to receive care ≥1 year after diagnosis (HR=2.02, 95%CI: 1.30-3.15), their CD(4) cell count less than 200 cells/μl (HR=3.41, 95%CI: 2.59-4.59) at the time of diagnosis, with NVP in antiviral treatment (ART) regime (HR=1.36, 95%CI: 1.03-1.88), at Ⅲ/Ⅳ clinical stages (HR=2.61, 95%CI: 1.94-3.53) and CD(4) cell count less than 350 cells/μl (HR=5.48,95%CI: 2.32-12.72) at initiation of HAART ect., were more likely to die of AIDS-associated diseases. Conclusions: With the existence of competing risks, the cumulative incidence rate for AIDS-related death was overestimated by K-M, suggesting that competing risk models should be used in the survival analysis. Measures as early diagnoses followed by timely care and early HAART could end up with the reduction of AIDS-related death.

Abstract
The aberrant expression of microRNA-375 (miR-375) has been proved to be associated with carcinogenesis. However, the role of miR-375 in glioblastoma (GBM) remains unknown. The aim of this study was to investigate biological functions and its molecular mechanisms of miR-375 in GBM cells. In this study, real-time PCR results showed that the level of miR-375 expression in GBM tissues and GBM cell lines (U87 and U251) was decreased. Using MTT assay, Transwell migration and invasion assay, we demonstrated that miR-375 overexpression significantly suppress cell proliferation, cell migration and cell invasion capacity in U87 and U251 cells. However, downregulation of miR-375 had reverse effects on cell proliferation, migration and invasion. Targeting association analysis, dual luciferase assay, RT-PCR and western blot analysis results confirmed that miR-375 could target the 3'UTR of Wnt5a mRNA and regulated its protein expression. Further studies also find overexpression of Wnt5a could significantly reverse miR-375-mediated proliferation, migration and invasion on U87 and U251 cells. Therefore, we concluded that miR-375 inhibited the proliferation and invasion of GBM by regulating Wnt5a and might be a possible therapeutic agent for GBM.

Abstract
Dysphagia is the most significant symptom in patients with esophageal cancer. There are different therapeutic interventions designed to relieve dysphagia, but few studies have addressed the effects of neoadjuvant therapy. The aim of this study is to compare the effects on dysphagia of neoadjuvant chemotherapy (nCT) versus neoadjuvant chemoradiotherapy (nCRT) and further to study the association between dysphagia response and histological response. Patient reported swallowing function was a secondary endpoint in the NeoRes trial, in which patients were randomized between neoadjuvant chemotherapy or neoadjuvant chemoradiotherapy. Patients completed dysphagia questionnaires before the start and after neoadjuvant therapy, using the European Organization for Research and Treatment of Cancer (EORTC) esophageal cancer modules QLQ-OES24/OG25. Chirieac tumor regression grade (TRG) was used to assess the histological response. Out of 181 patients were randomized, of whom 87% completed the dysphagia questionnaires before and 73% after neoadjuvant treatment. Patient characteristics were similar between the treatment arms. Among patients reporting dysphagia at baseline, neoadjuvant therapy improved dysphagia in both arms. The mean dysphagia score after neoadjuvant treatment was significantly lower after nCT compared to after nCRT (P = 0.022). The reported dysphagia did not differ between those with a complete histological response (TRG 1) and those without any response at all (TRG 4) (P = 0. 583).

Abstract
The aim of the present study was to evaluate the effects of Lactobacillus rhamnosus GG (LGG; ATCC 53013) on growth performance and hepatotoxicity in calves fed a single dose of aflatoxin B1 (AFB1) and to investigate the absorption, distribution, and elimination of AFB1 and the hydroxylated metabolite aflatoxin M1 (AFM1) in rumen fluid, blood, and excretions. Twenty-four male Holstein calves were blocked for body weight and age and were randomly assigned to 1 of 3 treatment groups: (1) untreated control, (2) treated with 4.80 mg of AFB1 (AFB1 only), or (3) treated with 1 × 1010 cfu of LGG suspension and 4.80 mg of AFB1 (AFB1 plus LGG). The calves received LGG suspension in 50 mL of phosphate-buffered saline daily via oral administration for 14 d before and on the day they received a single oral dose of AFB1. Body weight was recorded at the beginning of the study (before LGG administration), at the day of AFB1 administration, and at the end of the trial. Rumen fluid, blood, urine, and feces samples were collected continuously for 96 h after AFB1 administration. Average daily gain (ADG) and plasma biochemical parameters were analyzed, and concentrations of AFB1 and AFM1 in the samples were determined for monitoring excretion pattern and toxicokinetics. The results showed that ADG was lower in AFB1-treated animals; LGG administration partially mitigated the decrease in ADG (0.85 ± 0.08 vs. 0.76 ± 0.18 kg of gain/d). The AFB1 treatment increased plasma aspartate aminotransferase, alkaline phosphatase, and lactate dehydrogenase levels. Administration of LGG alleviated the AFB1-induced increase in plasma enzymes activity. The excretion patterns of AFB1 and AFM1 were surprisingly regular; toxins were rapidly detected in all samples after a single oral dose of AFB1, and the peak of toxins concentrations was sequentially reached in rumen fluid, plasma, urine, and feces (except AFM1 in rumen fluid), followed by an exponential decrease. The excretion curves showed that AFB1 and AFM1 concentrations were the highest in feces and urine, respectively. Administration of LGG decreased the concentrations of free AFB1 and AFM1 in rumen fluid and reduced the release of toxins into plasma and urine. Toxicokinetic parameters (except for the time of maximum concentration and the terminal half-life) were reduced by LGG administration. In conclusion, the absorption, distribution, and excretion of AFB1 and AFM1 were rapid in calves fed a single dose of AFB1. Urine was the main route for the excretion of AFM1, and the clearance pattern from the peak of concentration was well fitted by exponential decreasing function. Administration of LGG reduced the absorption of AFB1 in the gastrointestinal tract by increasing the excretion via the feces, thus alleviating the hepatotoxic effect of AFB1.

Abstract
Objective: To describe and analyze the passive smoking exposure level in adults aged ≥40 years in China. Methods: A total of 75 107 adults from 125 sites of COPD surveillance points in China were surveyed by electronic questionnaire during face to face interviews. After comprehensive weighting of the samples, the passive smoking exposure level was analyzed. Results: The passive smoking exposure rate of the adults aged ≥40 years was 44.9% (95%CI: 42.3%-47.5%). The exposure rate was highest in those aged from 40 to 49 years (51.0%, 95%CI: 47.9%-54.1%) in term of age groups, in those with senior high school education level and above (48.6%, 95%CI: 44.9%-52.2%) in term of education level, and in office workers (57.7%, 95%CI: 51.8%-63.7%) in term of occupation. The adults reporting passive smoking exposure every days in a week accounted for 27.7% (95%CI: 25.5%-29.8%), and those reporting household passive smoking exposure accounted for 28.3% (95%CI: 26.2%-30.5%). Logistic regression analysis showed that the passive smoking exposure level was different in different age groups and occupation groups. Conclusion: The passive smoking exposure level is still high in adults in China. Age and occupation are the influencing factors of passive smoking exposure level.

Abstract
Objective: Smoking is the most important risk factor for COPD. Understanding the smoking rate, current smoking rate, average age to start smoking and average daily consumption of cigarettes among people aged ≥40 years in China can provide scientific evidence for the effective control and prevention of COPD. Methods: Data were from COPD surveillance in China (2014 to 2015) which covered 31 provinces, autonomous regions and municipalities. A total of 75 107 adults aged ≥40 years selected through multi-stage stratified cluster sampling from 125 surveillance sites (county/district) were surveyed by electronic questionnaire during face to face interviews. The smoking rate and other smoking index were estimated by using weighting complex sampling design. Results: The smoking rate and current smoking rate were 40.0% (95%CI: 38.5%-42.0%) and 31.0% (95%CI: 29.7%-32.0%), respectively, among the Chinese aged ≥40 years in 2014. The smoking rate and current smoking rate in males (74.1% and 57.6%) were much higher than those in females (5.4% and 4.0%). And the two rates were significantly higher in rural area (41.2% and 32.4%) than in urban area (38.8% and 29.5%). The mean age of smokers to start smoking was 20.1 (95%CI: 19.7-20.5) years. The younger the smokers were, the earlier their average age to start smoking was (The ages to start smoking for smokers aged 40-, 50-, 60-, ≥70 years were 18.3, 19.2, 20.9 and 23.1 years, respectively). Average daily cigarette consumption of current daily smokers was 18.9 (95%CI: 18.1-19.7) cigarettes, and the daily cigarette consumption was higher in males (19.3 cigarettes) than in females (12.5 cigarettes). Conclusion: The smoking rate in males aged ≥40 years is high in China. Compared with urban area, the smoking rate in rural area is higher, posing a big challenge for COPD control and prevention.

Abstract
Objective: To understand the performance of spirometry examination in adults aged ≥40 years and provide evidence for the improvement of comprehensive prevention and control of COPD and the evaluation on the effects of current prevention and control measures. Methods: The study subjects were those included in national COPD surveillance in China during 2014-2015. The surveillance used a multi-stage, stratified cluster sampling strategy and a total of 125 surveillance points in 31 provinces were covered. A total of 75 107 adults aged ≥40 years received a questionnaire survey in face to face interviews to collect the information about their acceptance of spirometry examination in previous years. The estimated rate (95%CI) of spirometry examination was calculated based on complex sampling weight design. Results: A total of 74 591 subjects were included in the analyses. The estimated rate of spirometry examination was 4.5% (95%CI: 3.7%-5.2%), and it was significantly higher in men than in women (P<0.001), in urban population than in rural population (P<0.001). The rate of spirometry examination increased with the increase of education level (P<0.001). The rate of spirometry examination was highest in retirees (10.8%, 95%CI: 8.2%-13.3%), and lowest in those working in the industry of agriculture, forestry, animal husbandry, fishery and water conservancy (2.4%, 95%CI: 2.0%-2.9%). The rate of spirometry examination was high in those with previous chronic respiratory diseases and respiratory symptoms, i.e. 13.4% (95%CI: 10.5%-16.4%) and 15.0% (95%CI: 10.5%-19.4%) respectively. The rate of spirometry examination in former smokers was 7.4% (95%CI: 6.0%-8.8%), slightly higher than those in current smokers and never smokers, 4.7% (95%CI: 3.9%-5.5%) and 3.9% (95%CI: 3.0%-4.7%), respectively. In different population groups, the rate of spirometry examination was lowest in rural population who had received no formal education (1.8%, 95%CI: 1.2%-2.3%) and highest in urban population with respiratory symptoms (20.2%, 95%CI: 12.6%-27.8%). Conclusion: The rate of spirometry examination is extremely low in adults aged ≥40 years in China, therefore effective measures should be taken to increase the rate of spirometry examination in adults in China.

Abstract
Objective: To understand the distribution and characteristics of people aged ≥40 years who are at high risk of COPD in China and provide evidence for COPD prevention and control. Methods: The survey was conducted among the subjects selected through multi-stage stratified cluster sampling from 31 provinces (autonomous regions and municipalities) in China for 2014-2015 national chronic obstructive pulmonary disease surveillance. A total of 75 107 people aged ≥40 years in 125 surveillance points were surveyed in face to face interviews. Subjects who met at least one of the following conditions, including chronic respiratory symptoms, exposure to risk factors, medical history of respiratory diseases, and family history, were defined as population at high risk. The weighted proportion of the population at high risk of COPD and 95%CI were estimated by using complex sampling design. Results: Among eligible 74 296 subjects, the proportion of population at high risk of COPD was 89.5% (95%CI: 87.8%-91.2%). The proportion significantly increased with age (P<0.001). The proportion of the population at high risk was significantly higher in men than in women (P<0.001), and in rural area than in urban area (P<0.001). The highest proportion of population at high risk was observed in men in rural area in western China. The proportion of population at high risk of COPD who met at least two conditions was 32.0% (95%CI:29.7%-34.2%), the proportion of those who met at least three conditions was 7.4% (95%CI: 6.6%- 8.3%), and the proportion of those who met all the conditions was 1.5% (95%CI: 1.2%-1.8%). Among population at high risk of COPD, those who only had exposure to one risk factor accounted for 61.7% (95%CI: 59.8%-63.7%). Conclusion: About 90% of people aged ≥40 years in China are at high risk for COPD. It is necessary to conduct population-based screening for COPD and take comprehensive measures to reduce prevalence of risk factors.

Abstract
Objective: To understand the prevalence of biomass fuel exposure in women aged ≥40 years in China during 2014-2015, and provide evidence for the prevention and control of bio-fuel exposure. Methods: All participants were selected from a national representative cross-sectional survey during 2014-2015 in the mainland of China. A multi-stage stratified cluster sampling strategy was used. A total of 37 795 women aged ≥40 years received a face-to-face questionnaire survey at 125 surveillance points in 31 provinces. The level of biomass fuel exposure was analyzed after complex sample weighting to represent the overall Chinese women aged ≥40 years. Results: A total of 37 777 women were included in the analysis. With complex weighting, the rate of biomass fuel exposure in Chinese women aged ≥40 years was 35.8% (95%CI: 29.6%-42.1%), the exposure rate was higher in rural women than in urban women (P<0.001). The biomass fuel exposure rate was highest in northeastern and lowest in northern areas of China (χ(2)=17.03, P=0.009). The estimated biomass fuel exposure rate decreased with the increase of educational level (P<0.001). Conclusion: The prevalence of biomass fuel exposure is high in women aged ≥40 years in China, especially in those in rural areas. The exposure level differs with age and area. Appropriate measures should be taken to reduce the level of biomass fuel exposure in Chinese women.

Abstract
Objective: To understand the current status of dust and/or harmful gas exposure in adults aged ≥40 years and corresponding protection in China, and provide evidence for strengthening the occupational protection against dust and harmful gas exposure. Methods: The data were obtained from 2014-2015 COPD surveillance in China. A total of 75 107 adults aged ≥40 years selected through multi-stage stratified cluster sampling from 125 surveillance points in 31 provinces (autonomous regions and municipalities) were surveyed in face to face interviews. Occupational exposure was defined as occupational exposure to dust and/or harmful gas for more than 1 year. The weighted percentages of exposure were estimated by using complex sampling design. Results: Among eligible 71 061 participants, the exposure rate of dust and/or harmful gas was 46.3%. The exposure rate in rural area (51.7%) was significantly higher than that in urban area (40.3%), and the exposure rate in the western area was higher than those in the eastern and central areas (P<0.001). Among the groups with different education level, the exposure rate in those with education level of primary school and below was highest (49.7%, P<0.001). The exposure protection rate was 26.7%, and the exposure protection rate was highest in the eastern area (29.9%), followed by that in the central area (27.0%) and that in the western area (22.9%) The exposure protection rate in urban area was significantly higher than that in rural area, and the exposure protection rate was lowest in those with education level of primary school and below. The regular exposure protection was taken by only 50.7% of the adults surveyed. Conclusion: The exposure rate of dust and/or harmful gas is high in China, while the exposure protection rate is very low. Health education, occupational protection and supervision should be strengthened among those with low education level, and those living in rural area and in the western area.

Abstract
Objective: To understand the awareness of knowledge about COPD and related factors in residents aged ≥40 years in China. Methods: Through multi-stage stratified cluster sampling, residents aged ≥40 years were selected from 125 sites of COPD surveillance (2014-2015) in 31 provinces of China for a face to face questionnaire survey. The demographic characteristics and awareness rate of knowledge about COPD among 75 082 subjects were described as frequency and percentage. The awareness rate of knowledge about COPD and its 95% confidence interval (CI) among the residents aged ≥40 years were estimated with complicated sampling weights. Meanwhile, the knowledge awareness related factors were screened in complicated sampling data. Results: The awareness rate of COPD was 9.2%. The awareness rate of pulmonary function test was 3.6% and the awareness rate of COPD-related knowledge was 5.8%. All of the awareness rates were associated with gender, age, education level and occupation. Besides, the awareness rate of pulmonary function test and COPD-related knowledge were related with living area. Compared with females, the ORs of the three awareness rates among males were 0.88, 0.81 and 0.78. Compared with the residents aged ≥70 years, the ORs of the three awareness rates among those aged 60-69 years were 1.28, 1.08 and 1.51. Compared with the residents with education level of primary school or below, the ORs of the three awareness rates among those with college degree or above were 2.28, 3.43 and 3.14. The OR of the awareness rate of pulmonary function test among the residents in the eastern area was 1.77 compared with those in the central area. The ORs of the awareness rate of COPD-related knowledge among the residents in the eastern and western areas were 1.95 and 2.16 compared with those in the central area(all above P<0.05). Among COPD symptoms, the awareness rate of dyspnea was highest (67.9%), and among the risk factors for COPD, the awareness rate of smoking was highest (81.3%). The source of awareness of COPD for most residents was television program (38.2%). Conclusion: The awareness rate of knowledge about COPD was low in residents aged ≥40 years in China in 2014. It is necessary to strengthen the health education about COPD to improve the prevention and control of the disease.

Abstract
Objective: To investigate the prevalence and associated factors of chronic kidney diseases (CKD) in adult residents living in a community of Songjiang district, Shanghai. Methods: A total of 9 257 residents aged 20-75 years old in Xinqiao township of Songjiang district were selected by random cluster sampling. All the participants were interviewed to complete a set of personal questionnaire and undergo physical examinations. Urine and blood tests including markers of kidney damage and related associated factors with CKD, were carried out. Results: Eligible data from 8 207 subjects were enrolled in the study. After adjustment for age and gender, the prevalence of CKD was 8.4% (95%CI: 7.8%-9.0%), with majority of the patients (76.5%) appeared in the early stage (Ⅰ and Ⅱ) of the disease. The prevalence of CKD increased with age and higher prevalence was seen in females than in males (P<0.001). Results from logistic regression analysis showed that factors as: being elderly or female, having hypertension, hyperuricemia, and hyperlipidemia were all independently associated with CKD. Conclusions: The prevalence of CKD appeared relatively high in adult residents of Xinqiao township, Songjiang district where CKD had become a public health problem. Factors as: being female or elderly, hypertension, hyperuricemia, and hyperlipidemia were found to be associated with CKD. Our findings suggested that early prevention and control on CKD to reduce the incidence of end-stage renal diseases and related complications had called for more urgent attention.

Abstract
BACKGROUND AND AIMS Therapeutic possibilities now exist to lower low-density lipoprotein cholesterol (LDL-C) to very low levels. However, substantial controversy remains in clinical practice with regard to its safety, and the question of whether low LDL-C levels per se may provoke adverse effects in humans arises. We aimed to explore the association of LDL-C with androgen and erectile dysfunction (ED) in a general population of men. METHODS AND RESULTS A total of 4203 men without hormone replacement therapy were enrolled from 22 sites in East China. Total testosterone (T) and Free T were assessed. Free androgen index (FAI) was calculated. The IIEF-5 questionnaire was used to assess ED. We found that free T and FAI gradually and markedly increased with increasing LDL-C levels. Using linear regression, after adjusting for age, educational level, economic status, smoking status, drinking status, BMI, diabetes, and use of lipid-lowering medication, LDL-C was positively associated with free T (B = 0.175, 95% CI: 0.084, 0.266) and FAI (B = 0.064, 95% CI: 0.016, 0.112). Meanwhile, there was a U-shaped curvilinear relationship between LDL-C and prevalence of ED. In the logistic regression analysis, compared to those with LDL-C among the 10th-90th percentile, the ORs of ED in men in the lowest and highest deciles were 1.938 (95% CI: 1.121, 3.349) and 1.804 (95% CI: 1.117, 2.916), respectively. CONCLUSION Lower LDL-C levels were significantly associated with lower free T and lower FAI in a general population of men. Moreover, both low and high levels of LDL-C might be risk factors for ED.

Abstract
Objective: To investigate the safety and efficacy of percutaneous intervention of children with combined congenital heart abnormality solely guided by transthoracic echocardiography (TTE) . Methods: From September 2015 to June 2017, 21 children with combined congenital heart abnormality undergoing percutaneous interventional guided by TTE in Fuwai hospital were enrolled in our study, and the clinical data were retrospective analyzed. The atrial septal defect(ASD) closure, ventricular septal defect(VSD) closure, patent ductus arteriosus(PDA) closure or balloon pulmonary valvuloplasty were performed under the guidance of TTE. The procedural effect was evaluated by TTE after operation. The patients were followed up after discharged from the hospital. Results: The age was (37.3±11.6) months, and there were 9 male and 12 female patients. There were 4 cases with ASD and VSD, 6 cases with VSD and PDA, 6 cases with ASD and PDA, 2 cases with VSD and pulmonary stenosis, 3 cases with ASD and pulmonary stenosis. The operations were successfully performed in all patients. No one required extra X ray guidance or open heart surgery. The operation time was (44.6±7.5)min. All patients did not require blood transfusion, inotropic support, and analgesia. There were no complications such as peripheral vascular injury and pericardialeffusion after the operation. The length of hospital stay time was (3.5±0.6) days. All patients were recovered well. The follow-up was (17.6±5.2) months, and post-procedural conduction disturbances, residual shunts, occlude fall off, thrombosis, and new onset of valvular regurgitation were not observed in these patients. Conclusion: Percutaneous interventional of children with combined congenital heart abnormality solely guided by TTE is safe and effective, and the procedure can avoid the potential injuries of X ray and contrast agent.

Abstract
Objective: To explore the association between the consumption of chemical fertilizers and the risk of low birth weight (LBW), to provide references for prevention programs on LBW and to improve the birth outcomes. Methods: Stratified multivariate logistic regression method was used in this study involving 153 preterm LBW infants, 179 term LBW infants and 204 normal control infants that were randomly selected from the birth monitoring data between October 2007 and September 2012 in Pingding county, Shanxi province. Associations between the risk of LBW and maternal exposure to chemical fertilizers during pregnancy were identified. A normal control group was set up to compare results between preterm and term LBW groups. Results: Totally, 18 749 infants were born between 2007 and 2012, with the total incidence rates of LBW as 48.5‰, preterm LBW as 19.4‰, and term LBW as 29.1‰. Concerning the case control study on preterm LBW, after adjustment for confounding factors, the risk of preterm LBW appeared 2.51 (95%CI: 1.05-5.99) times higher in villages with annual consumption of chemical fertilizer ≥100 tons than those villages that using chemical fertilizer less than 50 tons. No significant statistical associations were found between the amounts of household chemical fertilizer consumption and the risks of preterm LBW. Regarding the case control study on term LBW, after adjustment for confounding factors, in villages with ≥100 tons annual consumption of chemical fertilizers, the risk of term LBW was 4.03 (95%CI: 1.63-9.92) times of the risk in villages where the annal use of chemical fertilizers was less than 50 tons. There was no significant association between household consumption of chemical fertilizers and the risk of term LBW. Conclusions: Maternal exposure to chemical fertilizers during pregnancy was associated with the risk of LBW. Our findings suggested that the amount of chemical fertilizer consumption in rural areas seemed also associated with the risks of other adverse pregnancy outcomes. Women should avoid the chance of exposure to chemical fertilizers during pregnancy and the consumption of chemical fertilizers should be carefully managed.

Abstract
Limited studies indicate that mussels are generally insensitive to organic chemicals; however, these studies were conducted in acute or short-term exposures, and little is known about the chronic sensitivity of mussels to organic chemicals. We evaluated the chronic (28 days) toxicity of 4-nonylphenol (4-NP) to two commonly tested species of mussels: fatmucket (Lampsilis siliquoidea) and rainbow mussel (Villosa iris). By the end of the 28 days chronic exposures, mean survival was ≥93% in all treatments, but the mean dry weight and biomass of mussels at the highest exposure concentrations were significantly reduced relative to the control. The 20% effect concentrations were similar between the two species. When compared to all other tested species, fatmucket and rainbow mussels are among the top four most sensitive species to 4-NP. However, U.S. Environmental Protection Agency chronic water quality criterion of 6.6 μg 4-NP/L should protect the two mussel species.

Abstract
The Src homology and collagen A (ShcA) adaptor protein that binds to tyrosine kinase receptors. ShcA plays a role in insulin signaling, stress resistance and energy metabolism. The 66-kDa Src homology 2 domain-containing protein (p66shc) belongs to the ShcA family and has been associated with reactive oxygen species (ROS); increased ROS is involved in the pathology of lupus nephritis (LN). However, whether ShcA can act as a biomarker for oxidative injury in LN is unknown. This study is aimed to investigate the ShcA expression in kidney tissues from patients presenting with LN and the association between ShcA expression and clinical parameters. Renal biopsy tissues were obtained from 62 LN, 20 primary membranous nephropathy (MN) and 10 other secondary MN patients. ShcA was measured by immunofluorescence. The expression of ShcA in the membranous lupus nephritis (class V) group showed a higher trend but there were no significant differences compared with pure mesangial disease (class II) and proliferative (Class III/IV) lupus nephritis. ShcA deposits were negative in primary and other secondary MN. ShcA might act as a new biomarker and a diagnostic tool to identify membranous lupus nephritis with other MN.

Abstract
AbstractIn this work, the combustion, thermal, and mechanical performances of long-glass-fiber-reinforced polypropylene/intumescent flame retardant (LGFPP/IFR) composites with different contents of polyamide 6 (PA6) as a charring agent were investigated by limiting oxygen index (LOI), UL-94 test, cone calorimetry, thermal gravimetric analysis (TGA), scanning electron microscopy (SEM), and mechanical property test. The results showed that LGFPP/IFR/PA6 composites exhibited much better flame retardancy due to the dense char layer structure, as proved by SEM. When 15 wt% PA6 was added, the LGFPP/IFR composites had the best flame retardancy, and LOI increased by 55.1 %, and the UL-94 reached V-0 rating. The cone calorimeter tests indicated that PA6 could prevent the transmission of heat and the volatilization of flammable substances, thereby reducing the heat release of “second burning”. According to TGA analysis, the carbon layer began to form at a lower temperature due to the synergistic effect between IFR and PA6. Moreover, the calculation of apparent active energy (Ea) revealed that PA6 effectively increased the Ea values of the composites, resulting in a better thermal stability and flame retardancy. In addition, PA6 enhanced the mechanical properties of the composites effectively.

Abstract
OBJECTIVES This study aims to estimate the prevalence of sufficient physical activity (PA) for primary and high school students in China. STUDY DESIGN This is a meta-analysis study. METHODS The literature search was carried out using both English and Chinese online databases, including articles published from January 2005 to May 2018. Statistical analyses were performed with STATA 13.0. RESULTS Of 1439 articles initially retrieved, 18 studies met the inclusion criteria. The prevalence of sufficient PA among Chinese students varied from 8.96% to 56.02%. With meta-analysis, the sufficient PA prevalence was 31.1% (27.1%-35.2%). Boys were more likely to achieve sufficient PA compared to girls (boys vs girls: 42.4% vs 31.5%, P < 0.001), while urban students engaged in more sufficient PA than their rural counterparts (urban vs rural: 42.7% vs 38.5%, P < 0.001). Primary school students spent more time in overall PA than junior (primary vs junior: 45.4% vs 40.6%, P < 0.001) or senior high school students (primary vs senior: 45.4% vs 27.9%, P < 0.001). Students tended to be more physically active on weekdays than weekends (weekdays vs weekend: 57.2% vs 45.2%, P < 0.001). CONCLUSIONS The prevalence of sufficient PA was 31% among Chinese students. Intervention campaigns are needed for promoting PA level among students in China.

Abstract
Objective: To analyze the temporal trends of lung cancer incidence between age, gender (male and female) and areas (urban and rural) in Beijing during 2000-2012. Methods: The lung cancer cases were collected by Beijing cancer registry between 2000 and 2012. We calculated the incidence and world age-standardized incidence rates (ASR) which standardized by World Segi's population. Also, the average age and median age of lung cancer incidence were calculated. The annual percent changes (APC) for the whole period, for the gender ratio and for the area ratio were evaluated with Joinpoint analysis. Result: Totally, 81 378 new cases of lung cancer were diagnosed in 2000-2012 with the average incidence rate of 52.67/100 000. The incidence rate increased by 4.84% per year from 38.99/100 000 to 65.33/100 000, but the APC of ASR was 1.69% (P<0.001) . The ASR increased 0.54% (P=0.029) per year in urban from 29.71/100 000 to 30.55/100 000 and 3.93% (P<0.001) in rural areas from 24.02/100 000 to 35.79/100 000. The incidence ratio of urban to rural decreased from 1.24 to 0.85 (APC=-3.29%, P<0.001). The incidence ratio of male to female decreased from 1.84 to 1.69 (APC=-0.45%, P=0.019).The average age of lung cancer incidence of male and female increased from 66.27 and 66.00 to 68.97 and 69.11 (P<0.001), respectively. Conclusion: The incidence rate of lung cancer increased slightly in urban areas but increased significantly in rural areas during 2000-2012, the area ratio trend was declined. The average age of lung cancer occurrence gradually increased, but the temporal trends varied with age group. The gender ratio decreased from 2000 to 2012.
