Abstract
Objective: To prospectively explore the association between tea drinking and incidence of stroke of adults of Zhejiang province. Methods: After excluding participants with heart disease, stroke, cancer and diabetes at baseline study, 53 916 participants aged 30-79 years in the China Kadoorie Biobank (CKB) study from Tongxiang were included for final analysis. Cox regression model was used to estimate the hazard ratio (HR) for the association of tea drinking with incident stroke. Results: The main type of drinking tea was black tea (79.78%), followed by green tea (20.08%). Of the 53 916 participants, the proportion of participants who drank tea at least once per week was 31.27%. The corresponding proportions for men and women were 60.24% and 10.30%, respectively. Among 391 512 person-years of the follow-up program (median 7.26 years), a total of 1 487 men and 1 769 women were diagnosed with stroke. After adjusting for socio-demographic status, lifestyle, BMI, waist circumference, and systolic blood pressure, HR for incident stroke decreased with the increase of daily average tea consumption amount (P=0.000 6). Compared with participants who did not drink tea weekly, the HRs for incident stroke in those consuming tea 0.1-, 3.0- and ≥5.0 g/d were 0.93 (95%CI: 0.85-1.00), 0.88 (95%CI: 0.77-0.99) and 0.79 (95%CI: 0.69-0.89), respectively. The HRs for incident stroke in smokers and non-smokers who consumed tea ≥5.0 g/d were 0.71 (95%CI: 0.59-0.86) and 0.97 (95%CI: 0.77-1.21), respectively, compared with current smokers and non-smokers who did not drink tea weekly (P=0.040 0). The corresponding HRs for alcohol drinkers and non-drinkers were 0.96 (95%CI: 0.76-1.22) and 0.70 (95%CI: 0.58-0.84), respectively (P=0.040 0). The corresponding HRs for central obese persons and non-central obese persons were 0.60 (95%CI: 0.44-0.81) and 0.86 (95%CI: 0.73-1.01), respectively (P=0.040 0). Conclusion: Tea drinking had an effect on reducing the possibility of incident stroke, especially among those who were current smokers, non-alcohol drinkers and central obese.

Abstract
Objective: To describe the characteristics of cooking and heating fuel use in participants from the China Kadoorie Biobank (CKB) study. Methods: The CKB study recruited 512 891 adults from 10 areas in China during 2004-2008. Information on cooking fuel and heating fuel was collected using a questionnaire in baseline survey. The proportions of various fuels used in different areas, in different populations, and at different time points were calculated and compared. Results: Overall, 52.1% participants used solid fuel for cooking or heating. Rural areas had higher prevalence of solid fuel use than urban areas. The percentage of participants using solid fuel for cooking was 36.1% (coal 20.1%, wood/charcoal 16.0%); The percentage of participants using solid fuel for heating was 36.7% (coal 22.7%, wood/charcoal 14.0%). The prevalence of solid fuel use and the fuel type mainly used varied widely across 10 areas. The proportion of clean fuel use was lower in less-educated and lower-income people. Household coal and wood/charcoal use showed a declining trend, which was more remarkable in urban areas. Conclusion: There are still a large number of rural residents and people with low income relying on solid fuel in China, which is a serious public health concern.

Abstract
Objective: To study the relationship between the age of menarche and the near-term/long-term obesity in adult women. Methods: We analyzed the baseline data of 30 895 women with complete data on menarche and body measurement that was from the China Kadoorie Biobank (CKB) study from 2004 to 2008. The age of menarche was divided into three groups: ≤12, 13-16 and ≥17 years old. Prematurity was set at age ≤12 years. Multivariate logistic regression was used to analyze the effects of menarche age on the near/long-term obesity in female adults. Results: The average menarche age of respondent appeared as (15.64±1.92) years old, with prematurity number as 1 421, accounting for 4.6% of the total numbers. Regarding the postponing of dates of birth, the age of menarche in women showed an advancing tendency. Among all the adult women under study, 803 developed near-term obesity, with the prevalence as 2.6%, while the number of long-term obesity was 3 738, accounting for 12.1%. Refining factors of age, lifestyle, menopausal status, hypertension and diabetes showed that the menarche age was related to the risks of both short-term and long-term obesity in women and the ORs (95%CI) were 2.45 (1.74-3.45) and 1.99 (1.69-2.34), respectively. There was no multiplicative interaction shown between the menarche age and menopausal status on long-term obesity (P=0.324). Conclusion: Premature menarche appeared a risk factor for near-term/long-term obesity in adult females.

Abstract
Objective: To examine the prevalence of 'healthy lifestyle' from data extracted from the China Kadoorie Biobank (CKB) of 0.5 million adults from ten areas across China. Methods: After excluding participants with self-reported histories of coronary heart disease, stroke or cancer, a total of 487 198 participants at baseline (2004-2008) and 22 604 participants at second survey (2013- 2014), were included for analysis. 'Healthy lifestyle' was defined as haing the following characteristics: a) never smoking or having stopped smoking for reasons other than illness; b) alcohol drinking <25 g/day (men)/<15 g/day (women); c) diet rich in vegetables, fruits, legumes and fish, but low in red meat; d) upper quarter of the physical activity level; e) body mass index of 18.5-23.9 kg/m(2) and waist circumstance <85 cm (men)/80 cm (women). We calculated the healthy lifestyle scores (HLS) by counting the number of all the healthy lifestyle factors, with a range from 0 to 6. Results: At baseline, prevalence rates of the above five healthy lifestyles (except physical activity) were 70.6%, 92.6%, 8.7%, 52.6% and 59.0%, respectively, with the mean HLS being 3.1±1.2. Most participants (81.4%) had2-4 healthy components, while only 0.7% (0.2% in men and 1.0% in women) of all the participants had all six healthy lifestyles. Participants who were women, at younger age, with more schooling and rural residents, were more likely to adhere to the healthy lifestyle. After ten years, the mean HLS showed a slight decrease. Conclusion: The prevalence of optimal lifestyles in Chinese adults appeared extremely low. Levels of 'healthy lifestyle' varied greatly among those populations with different socio-demographic characteristics across the ten areas in China.

Abstract
Tea is a worldwide drink with controversial effect on bone health. The sex-specific associations are unrevealed among general population. This study showed that prolonged moderate tea consumption benefited bone health in women, while no additional benefit with stronger tea. However, tea consumption was not associated with bone health in men. INTRODUCTION Tea consumption has been shown a potentially beneficial effect on bone health in postmenopausal women. However, little is known about such association in men, and whether stronger tea instead harms bone health due to elevated urinary excretion of calcium associated with caffeine in the tea. The aim of this study was to examine the association between various metrics of tea consumption and bone health. METHODS The present study included 20,643 participants from the China Kadoorie Biobank (CKB), who have finished both baseline survey (2004-2008) and a re-survey (2013-2014). They were aged 38-86 years at re-survey. Tea consumption was self-reported at both baseline and re-survey. Bone mineral density (BMD) was measured using calcaneal quantitative ultrasound once at re-survey. RESULTS Compared with non-consumers, prolonged weekly tea consumers in women was associated with higher calcaneus BMD measures, with β (95% CI) of 0.98 (0.22, 1.74) for BUA, 4.68 (1.74, 7.61) for SOS, and 1.95 (0.81, 3.10) for SI. Among prolonged weekly tea consumers, no linear increase in BMD measures with the amount of tea leaves added was observed. The SOS and SI were higher in consumers with tea leaves 3.0-5.9 g/day than in those with < 3.0 g/day, but were reduced to non-significant for those with ≥ 6.0 g/day. Tea consumption was not associated with calcaneus BMD measures in men. CONCLUSION Prolonged moderate tea consumption benefited bone health in women but not in men. For stronger tea consumption with more tea leaves added, neither benefit nor harm to bone health was observed.

Abstract
Precision medicine became the key strategy in development priority of science and technology in China. The large population-based cohorts become valuable resources in preventing and treating major diseases in the population, which can contribute scientific evidence for personalized treatment and precise prevention. The fundamental question of the achievements above, therefore, is how to construct a large population-based cohort in a standardized way. The Chinese Preventive Medicine Association co-ordinated experienced researchers from Peking University and other well-known institutes to write up two group standards Technical specification of data processing for large population-based cohort study (T/CPMA 001-2018) and Technical specification of data security for large population-based cohort study (T/CPMA 002-2018), on data management. The standards are drafted with principles of emphasizing their scientific, normative, feasible, and generalizable nature. In these two standards, the key principles are proposed, and technical specifications are recommended in data standardization, cleansing, quality control, data integration, data privacy protection, and database security and stability management in large cohort studies. The standards aim to guide the large population-based cohorts that have been or intended to be established in China, including national cohorts, regional population cohorts, and special population cohorts, hence, to improve domestic scientific research level and the international influence, and to support decision-making and practice of disease prevention and control.

Abstract
Objective: To evaluate the association of educational level with anthropometric measurements at different adult stages and their long-term changes in adults who participated in the second re-survey of China Kadoorie Biobank (CKB). Methods: The present study excluded participants who were aged >65 years, with incomplete or extreme measurement values, or with major chronic diseases at baseline survey or re-survey. The weight at age 25 years was self-reported. Body height, body weight and waist circumference at baseline survey (2004-2008) and re-survey (2013-2014) were analyzed. Results: The present study included 3 427 men and 6 320 women. Both body weight and waist circumference (WC) increased with age. From age 25 years to baseline survey (mean age 45.2±6.5), the mean weight change per 5-year was (1.70±2.63) kg for men and (1.27±2.10) kg for women. From baseline survey to re-survey (53.2±6.5), the mean changes per 5-year for body weight were (1.12±2.61) kg for men and (0.90±2.54) kg for women; and that for WC was (3.20±3.79) cm for men and (3.83±3.85) cm for women. Among women, low educational level was consistently associated with higher body mass index (BMI) and WC at age 25 years, baseline survey and re-survey. Among men, low educational level was associated with higher BMI at age 25 years. At baseline survey and re-survey, the educational level in men was not statistically associated with BMI; but men who completed junior or senior high school showed slight higher WC and increase of WC from baseline survey to re-survey than other male participants. Conclusions: Body weight and WC increased with age for both men and women. The associations of educational level with BMI and WC were different between men and women.

Abstract
Objective: To describe the genetic structure of populations in different areas of China, and explore the effects of different strategies to control the confounding factors of the genetic structure in cohort studies. Methods: By using the genome-wide association study (GWAS) on data of 4 500 samples from 10 areas of the China Kadoorie Biobank (CKB), we performed principal components analysis to extract the first and second principal components of the samples for the component two-dimensional diagram generation, and then compared them with the source of sample area to analyze the characteristics of genetic structure of the samples from different areas of China. Based on the CKB cohort data, a simulation data set with cluster sample characteristics such as genetic structure differences and extensive kinship was generated; and the effects of different analysis strategies including traditional analysis scheme and mixed linear model on the inflation factor (λ) were evaluated. Results: There were significant genetic structure differences in different areas of China. Distribution of the principal components of the population genetic structure was basically consistent with the geographical distribution of the project area. The first principal component corresponds to the latitude of different areas, and the second principal component corresponds to the longitude of different areas. The generated simulation data showed high false positive rate (λ=1.16), even if the principal components of the genetic structure was adjusted or the area specific subgroup analysis was performed, λ could not be effectively controlled (λ>1.05); while, by using a mixed linear model adjusting for the kinship matrix, λ was effectively controlled regardless of whether the genetic structure principal component was further adjusted (λ=0.99). Conclusions: There were large differences in genetic structure among populations in different areas of China. In molecular epidemiology studies, bias caused by population genetic structure needs to be carefully treated. For large cohort data with complex genetic structure and extensive kinship, it is necessary to use a mixed linear model for association analysis.

Abstract
Objective: To explore the effect of BMI and waist circumference on diabetes of adults. Methods: After excluding participants with heart disease, stroke, cancer and diabetes at baseline study, 53 916 people aged 30-79 in the China Kadoorie Biobank (CKB) study from Tongxiang city of Zhejiang province were recruited. Cox regression model was used to estimate the hazards ratios (HR) for the associations of baseline BMI and waist circumference with incident diabetes. Results: Among 391 512 person-years of the follow-up program between 2004 and 2013 (median 7.26 years), a total of 944 men and 1 643 women were diagnosed as having diabetes. Compared to those with normal weight, after adjusting for known or potential factors, HR of both overweight and obesity in men for incident diabetes appeared as 2.72 (95%CI: 2.47-2.99) and 6.27 (95%CI: 5.33-7.36), respectively. The corresponding figures in women were 2.19 (95%CI: 2.04-2.36) and 3.78 (95%CI: 3.36-4.26). Compared to those with normal waist circumference, after adjusting for known or potential factors, HR of Ⅰgrade andⅡgrade in men for diabetes were 2.56 (95%CI: 2.22-2.95) and 4.66 (95%CI: 4.14-5.24), respectively. The corresponding figures in women were 1.99 (95%CI: 1.80-2.21) and 3.16 (95%CI: 2.90-3.44), respectively. Conclusions: Overweight, obesity and central obesity were all associated with the increased incident of diabetes. Strategies on diabetes prevention should include not only losing weight, but reducing waist circumference as well.

Abstract
Objective: To study the relations between famine exposure and the risk of chronic diseases as diabetes mellitus, obesity, hypertension, coronary heart disease and stroke in the population of Harbin. Methods: Our data was collected from the baseline survey-the China Kadoorie Biobank project (CKB) in Harbin. Retrospective cohort study design was used. Related risks on chronic diseases including diabetes mellitus, obesity, hypertension, coronary heart disease and stroke, were compared among the famine exposed or non-exposed people, respectively by logistic analysis method. Results: After adjusted for factors as age, sex, physical activity, smoking, alcohol intake, diet, family history of diseases, it appeared that the factor 'famine exposure' had increased the risks of diseases as obesity (OR=1.204, 95%CI: 1.104-1.313, P<0.01), hypertension (OR=1.315, 95%CI: 1.210-1.429, P<0.01) and coronary heart disease (OR=1.495, 95%CI: 1.369-1.632, P<0.01). The lower the age of population being exposed to famine, the greater the risk of the development of all kinds of chronic diseases. Conclusions: Famine exposure appeared a risk factor for obesity, hypertension, and coronary heart disease. It is of great significance to ensure the life-long nutrition of the people, especially in the early and adolescent stages, to prevent obesity, hypertension, and coronary heart disease in their later lives.

Abstract
Objective: To understand the association between central obesity, assessed by waist circumference, and the risks for ischemic heart disease (IHD), major coronary event (MCE), and IHD death. Methods: After excluding participants with heart disease, stroke, cancer, COPD, and diabetes at baseline survey, we included a total of 428 595 participants from the China Kadoorie Biobank for the analysis. The baseline survey was conducted from June 2004 to July 2008. We used Cox proportional hazards model to estimate the hazard ratio (HR) and 95%CI. Results: During an average 9.1 years of follow-up (3 803 637 person-years), we documented 26 900 incident cases of IHD, 4 320 cases of MCE, and 2 787 of deaths from IHD. After adjustment for possible confounders and BMI, central obesity was found to be associated with increased risks for IHD, MCE, and IHD death. The adjusted HRs (for the participants who had waist circumference of 85.0-89.9 cm in men and 80.0-84.9 cm in women were 1.13 (95%CI: 1.09-1.17) for IHD, 1.15 (95%CI: 1.05-1.26) for MCE and 1.11 (95%CI: 0.98-1.24) for IHD death. The respective HRs for those central obese participants (men ≥90.0 cm, women ≥85.0 cm) were 1.29 (95%CI: 1.24-1.34), 1.30 (95%CI: 1.17-1.44) and 1.32 (95%CI: 1.16-1.51). Further stratification analysis according to BMI showed that the risks for incident IHD, MCE, and IHD death increased along with the increase of waist circumference even in the participants with normal weight. Conclusion: This large-scale prospective study revealed that central obesity was an independent risk factor for IHD in adults in China, and the risk of IHD would increase with the increase of waist circumference.

Abstract
Osteoporosis is a serious health problem worldwide. Semaphorins (Sema) have been described as key molecules involved in the cross-talk between bone cells (osteoblasts/osteoclasts). In this study, we investigated whether plasmid containing Sema3a could ameliorate bone loss in an ovariectomized (OVX) mouse model via (AspSerSer)6, a selectively bone-targeting moiety. Plasmid pcDNA3.1(+)-Sema3a-GFP was fabricated and transfected cells with the plasmid demonstrated statistically higher levels of Sema3A in vitro (p < 0.001). Mice were ovariectomized and injected twice weekly with (AspSerSer)6-(STR-R8)+pcDNA3.1(+)-Sema3a-GFP for four weeks. The aim of the study was twofold: firstly to design an effective bone-targeting drug-delivery system (AspSerSer)6. Secondly, the effects of Sem3A gene therapy on bone loss was investigated. Here, the targeting selectivity of pcDNA3.1(+)-Sema3a-GFP via (AspSerSer)6 to the trabecular bone surface was firstly verified by histological observation of frozen sections and immunofluorescence staining. Then, bone microstructure analysis by Micro-CT indicated significantly less bone loss in mice treated with (AspSerSer)6-(STR-R8)+pcDNA3.1(+)-Sema3a-GFP compared to the control group (p < 0.05). Furthermore,H&E staining and Safranin O staining of the decalcified sections demonstrated statistically significantly higher bone area/total area in the mice that were injected with (AspSerSer)6-(STR-R8)+pcDNA3.1(+)-Sema3a-GFP (p < 0.001, p < 0.01,respectively). TRAP staining and immunohistochemistry staining of COL I demonstrated lower numbers of osteoclasts and significantly increased numbers of osteoblasts in the bone-targeting moiety delivering pcDNA3.1(+)-Sema3a-GFP group, when compared to the control group (p < 0.01, p < 0.001,respectively). Together, our findings have identified that, (AspSerSer)6, a bone-targeting drug-delivery system based on semaphorin3A gene therapy, ameliorated bone loss in osteoporotic ovariectomized mice, by suppressing osteoclastic bone resorption and simultaneously increasing osteoblastic bone formation. Gene therapy by local site-specific Sema3A overexpression might be a potential new strategy for treating osteoporosis and bone defects.

Abstract
Small airway obstruction is a main cause for chronic obstructive pulmonary disease (COPD). We propose a novel method based on machine learning to extract the airway system from a thoracic computed tomography (CT) scan. The emphasis of the proposed method is on including the smallest airways that are still visible on CT. We used an optimized sampling procedure to extract airway and non-airway voxel samples from a large set of scans for which a semi-automatically constructed reference standard was available. We created a set of features which represent tubular and texture properties that are characteristic for small airway voxels. A random forest classifier was used to determine for each voxel if it belongs to the airway class. Our method was validated on a set of 20 clinical thoracic CT scans from the COPDGene study. Experiments show that our method is effective in extracting the full airway system and in detecting a large number of small airways that were missed by the semi-automatically constructed reference standard.

Abstract
Objective: To examine the sex-specific associations between tobacco smoking and risk of cardiovascular diseases in Chinese adults. Methods: The present analysis included 487 373 participants from the China Kadoorie Biobank after excluding those with cancer, heart diseases, stroke at baseline survey. The baseline survey was conducted from June 2004 to July 2008. The number of follow-up years was calculated from the time that the participants completed baseline survey to the time of any event: CVD incidence, death, loss of follow-up, or December 31, 2015, whichever occurred first. We used Cox proportional hazards regression models to estimate the HRs and 95%CI of incident cardiovascular diseases with tobacco smoking. Results: During a median follow-up of 8.9 years(a total of 4.1 million person years), we documented 33 947 cases of ischemic heart diseases, 6 048 cases of major coronary diseases, 7 794 cases of intracerebral hemorrhage, and 31 722 cases of cerebral infarction. The prevalence of smoking was much higher in men (67.9%) than in women (2.7%). Smoking increased risk of all subtypes of cardiovascular diseases. Compared with nonsmokers, the multivariable-adjusted HRs (95% CI) for current smokers were 1.54 (1.43-1.66) for major coronary event, 1.28 (1.24-1.32) for ischemic heart disease, 1.18 (1.14-1.22) for cerebral infarction, and 1.07 (1.00-1.15) for intracerebral hemorrhage, respectively. Female smokers tended to have greater risk of developing major coronary event associated with amount of tobacco smoked daily (interaction P=0.006) and age when smoking started (interaction P=0.011). There was no sex difference in these two effects for ischemic heart diseases, intracerebral hemorrhage and cerebral infarction (all interaction P>0.05). Conclusions: This prospective study confirmed increased risk of all subtypes of cardiovascular diseases in current smokers. Smoking was more harmful to women than to men for major coronary event.

Abstract
Objective: To evaluate the association of family history with risk of major coronary events (MCE) and ischemic heart disease (IHD). Methods: After excluding participants with heart disease, stroke or cancer at baseline survey, a total of 485 784 participants from the China Kadoorie Biobank, who had no missing data on critical variables, were included in the analysis. Cox regression analysis was used to estimate the hazard ratios (HR) and 95% CI. Subgroup analyses were performed according to the baseline characteristics. Results: During a median of 7.2 years of follow-up, we documented 3 934 incident cases of MCE and 24 537 cases of IHD. In multivariable-adjusted models, family history was significantly associated with risk of MCE and IHD. The adjusted HRs (95%CI) were 1.41 (1.19-1.65) and 1.25 (1.18-1.33), respectively. History of disease among siblings was more strongly associated with early-onset MCE than parental history (HR=2.97, 95%CI: 1.80-4.88). Moreover, the association of family history with MCE and IHD was stronger in persons who were overweight or obesive, and the association between family history and MEC was stronger in smokers. Conclusion: This large-scale, prospective study indicated that family history was an independent risk factor for MCE and IHD in China. The intervention targeting major known lifestyle risk factors and the management of chronic diseases should be strengthened for Chinese population, especially for the individuals with family history were at high risk.

Abstract
Objective: To investigate gender specific differences in the association between stressful life events (SLEs) and depression in Chinese adults aged 30-79 years. Methods: In the baseline survey during 2004-2008, the China Kadoorie Biobank (CKB) recruited 512 891 men and women aged 30-79 years from 10 areas of China. Detailed information on SLEs, including demographic and socio-economic status, smoking, alcohol drinking and history of chronic disease, as well as depression symptoms and major depressive episodes (MDEs) in preceding 12 months, was collected by using standardized questionnaire. Multinomial logistic regression model was employed to estimate the relative risk ratio (RRR) and 95%CI of SLEs (3 categories, 10 items) on depression and the dose-response relationship between the number of SLEs experienced and depression. The interactions between gender and SLEs on depression were examined with likelihood ratio test. Results: Among the 512 891 participants, 35 085 (6.8%) reported family-related events, 5 972 (1.2%) reported finance-related events, and 4 453 (0.9%) reported other stressful life events. Females had a higher occurrence of family-related events, while males had a higher occurrence of finance-related and other events (all P-value <0.001). After adjusted for potential confounders, SLEs were significantly associated with MDEs (RRR=11.99, 95%CI: 10.49-13.71 for males; RRR=14.15, 95%CI: 12.97-15.43 for females), and with depressive symptoms (RRR=7.43, 95%CI: 6.94-7.95 for males; RRR=8.30, 95%CI: 7.91-8.72 for females). And the associations were stronger in females than in males (P for interaction=0.049). In the three categories of SLEs, family-related events showed stronger association in female (P for interaction <0.001), while no gender specific differences were observed for the other two categories (all P-value>0.05). Furthermore, the effect of the number of SLEs experienced increased in a dose-response manner on depressive symptoms and MDEs for both genders, but no gender specific differences were found. Conclusions: The gender modifies the association between stressful life events and depression in Chinese adults, and women experienced family-related events have a greater risk of depression. The more the stressful events experienced, the more likely to have depression.

Abstract
Objective: To examine the prospective associations between airflow obstruction (AFO) and risks of major chronic diseases morbidity in Chinese adults. Methods: Samples of this study were from the China Kadoorie Biobank. A total of 486 996 participants aged 30 to 79 years (mean 51.5 years) at the baseline study, were included after excluding those who self-reported of having heart disease, stroke and cancer at baseline. AFO was defined under the Global Initiative on Obstructive Lung Disease (GOLD) criteria and forced expiratory volume per one second in percentage of the expected one (FEV(1)% P). Cox regression models were used to investigate the associations of AFO with incidence rates of ischemic heart disease, cerebrovascular disease and lung cancer after adjusted for potential confounders. Results: Over a period of 7 years through the follow-up program, the incident cases of ischemic heart disease, cerebrovascular disease and lung cancer appeared as 24 644, 36 336 and 3 218, respectively. Compared with people without AFO, the HR (95% CI) of GOLD-1 to GOLD-4 were 0.89 (0.78-1.01), 1.05 (0.98-1.12), 1.29 (1.18-1.40) and 1.65 (1.42-1.91) respectively for ischemic heart disease. The HR (95%CI) of GOLD-1 to GOLD-4 were 0.96 (0.70-1.26), 1.12 (0.96-1.31), 1.38 (1.14-1.65) and 1.48 (1.05-2.02) respectively for lung cancer. No statistically significant differences in the associations between GOLD level and cerebrovascular disease morbidity were found. However, each 10% decrease in FEV(1)% P was associated with 7.2% (95%CI: 6.4%-8.0%), 3.6% (95%CI: 3.0%-4.3%) and 10.5% (95%CI: 8.4%-12.6%) increased the risks of ischemic heart disease, cerebrovascular disease and lung cancer respectively. The results were persistant when stratified by smoking status. Conclusion: Higher degree of AFO seemed to be associated with the risks of ischemic heart disease, cerebrovascular disease and lung cancer morbidity among the Chinese adults.

Abstract
Objective: To investigate the distribution of sleep duration, daytime naps habits, and insomnia-related symptoms among participants from the China Kadoorie Biobank (CKB) study, and to examine the associations between the sleep-associated factors. Methods: A self-designed computer-based questionnaire was adopted to collect social-demographic information and lifestyle-related factors of the participants. A total of 452 829 Chinese adults aged 30-79 years, without self-reported histories of coronary heart disease, stroke, chronic obstructive pulmonary diseases or cancer, were included in this study. General linear regression and multinomial logistic regression models were used to estimate the distributions on duration of sleep, daytime naps habits, and insomnia-related symptoms in different populations, after adjusted for gender, age, and residential regions. Gender-specific logistic regression model was adopted to examine the associations between the above mentioned sleep-related factors. Results: The average sleep duration of the participants was 7.41 hours per day, with 20.3% of them having daytime naps all year round, but 40.1% only had daytime naps in summer, and 39.6% had no habits of daytime naps. 11.0%, 10.0%, and 2.1% of the participants reported having had symptoms as difficulty in falling asleep, waking up too early or with daytime dysfunction, respectively. There were significant differences on the distributions in sleep-related factors between participants with different gender, age, residential areas, education levels,household income, and marital status (P<0.05). Results from the logistic regression showed that longer sleep duration was associated with lower risks of insomnia-related symptoms trend (P<0.001). Factor as without habits of daytime naps seemed to be associated with higher risks of insomnia-related symptoms (P<0.05). Participants with longer sleep duration were more likely to have the habit of taking daytime naps (P<0.05). Conclusions: The distributions of sleep duration, habits on daytime naps and insomnia-related symptoms varied according to the differences on social-demographic factors. There were associations existed between the sleeping-related factors, which would influence the promotion on optimal sleep duration and better quality of sleep.

Abstract
Objective: To explore the relationship between sleep status and the risk of diabetes in adults. Methods: The baseline data of 53 260 subjects who were aged 30-79 years and had been enrolled into China Kadoorie Biobank (CKB) study from Suzhou, Jiangsu province were analyzed. Multiple logistic regression models were used to investigate the association between sleep status and diabetes after adjusting for potential confounders. Results: Among 53 260 subjects, 5.3% had diabetes. The proportions of difficultly falling asleep, early morning arousal and snoring frequently was 7.2%, 10.0% and 29.5%, respectively. There were 22.6% of subjects reporting sleep duration ≤6 hours. After controlling for possible confounders, the subjects with difficulty falling sleep (OR=1.63 for male, 95%CI: 1.30-2.05; OR=1.48 for female, 95%CI: 1.27-1.73), early morning arousal (OR=1.37 for male, 95%CI: 1.12-1.68; OR=1.31 for female, 95%CI: 1.14-1.51) or snoring frequently (OR=1.16 for male, 95%CI: 1.00-1.34; OR=1.39 for female, 95%CI: 1.23-1.57) had a higher risk of diabetes. Using hypnotics regularly was associated with the risk of diabetes in females (OR=1.42, 95%CI: 1.06-1.92). Compared with 8 hours sleep duration daily, shorter sleep duration (≤6 hours) was associated with risk of diabetes in both males (OR=1.37, 95%CI: 1.17-1.60) and females (OR=1.24, 95%CI: 1.08-1.41). No statistical significant association was found between longer sleep duration (≥9 hours) and the risk of diabetes. Conclusion: Sleep problems, including difficulty falling asleep, early morning arousal, snoring frequently and shorter sleep duration, were associated with the risk of diabetes, but no statistical significant association was observed between longer sleep duration and the risk of diabetes.

Abstract
Objective: To investigate the prevalence of chronic obstructive pulmonary diseases (COPD) in Tongxiang, Zhejiang province, and analyze the interaction between smoking and indoor air pollution on COPD. Methods: Townships of Chongfu, Zhouquan, Gaoqiao, Shimen, Wuzhen were randomly selected from Tongxiang. All the local people aged 30-79 years were asked to receive questionnaire survey, physical examination and pulmonary function testing. FEV1max/FVC max≤0.7 was the criterion of COPD diagnosis. Logistic regression model was used to analyze the relationship between smoking/indoor air pollution and COPD, multiplied interaction between smoking and indoor air pollution was evaluated, Excel table prepared by Andersson et al. was used to calculate the adding interaction. Results: The overall prevalence of COPD was 6.6%, and adjusted for age, educational level, occupation, marriage, income level, BMI, waist-to-hip and other factors, multivariate logistic regression analysis showed that males who had quit smoking, started smoking at age of <25 years had a high risk of COPD; females who smoked every day <15 g, inhaled smoke into mouth or throat had high risk of COPD. Interaction analysis showed that using fuel of firewood/charcoal/coal, briquettes for cooking and regular smoking had multiplied interaction on COPD. Use no chimney or exhaust system in cooking and regular smoking had adding interaction in females. Conclusion: The prevalence of COPD in Tongxiang was close to the national average level. Female smokers had higher risk for COPD than male smokers. Improving kitchen ventilation, using natural gas or fuel gas for cooking and active tobacco control would facilitate the prevention of COPD.

Abstract
Osteoporosis is characterized by the imbalance of two relatively independent processes-osteoblastogenesis and osteoclastogenesis. Calcineurin (Cn)/nuclear factor of activated T cells (NFAT)(Cn/NFAT) signaling pathway is involved in these two processes in bone metabolism, but its potential as a target to treat osteoporosis needs to be defined. The aim of this study is to investigate the inhibition of polypeptide 11R-VIVIT onCn/NFAT signaling pathway. Rat calvaria (RC) cells were prepared from experimental model of osteoporosis in rat.11R-VIVIT wasused to treat cultured RC cells from wide type (WT) rat or from osteoporosis (OP) rat, we then measured the expressions of NFATc1, osteopontin (OPN), osteocalcin (OC), cytokines, NFκB subunit p65 by real time PCR, western blot or immunofluorescence. Then ALP expression and staining, and alizarin red S (ARS) staining were employed to study the osteoblastodifferentiation. 11R-VIVIT regulates the expression of NFATc1, and some other molecules in Cn/NFAT signaling pathway, such as OPN and OC, at transcriptional level and protein level. Further, it can regulate the expression of inflammatory cytokine like IL-1beta, IL-10 and TNF-alpha and NFκB activity. Further, 11R-VIVIT can accelerate osteoblastodifferentiation of RC cells demonstrated by ALP and ARS staining.11R-VIVIT can stimulate the bone formation by decreasing NFATc1 expression and regulating the expression of inflammation related molecules.

Abstract
BACKGROUND Worldwide 350 million people suffer from major depression, with the majority of cases occurring in low- and middle-income countries. We examined the patterns, correlates and care-seeking behaviour of adults suffering from major depressive episode (MDE) in China. METHOD A nationwide study recruited 512 891 adults aged 30-79 years from 10 provinces across China during 2004-2008. The 12-month prevalence of MDE was assessed by the Modified Composite International Diagnostic Interview-short form. Logistic regression yielded adjusted odds ratios (ORs) of MDE associated with socio-economic, lifestyle and health-related factors and major stressful life events. RESULTS Overall, 0.7% of participants had MDE and a further 2.4% had major depressive symptoms. Stressful life events were strongly associated with MDE [adjusted OR 14.7, 95% confidence interval (CI) 13.7-15.7], with a dose-response relationship with the number of such events experienced. Family conflict had the highest OR for MDE (18.9, 95% CI 16.8-21.2) among the 10 stressful life events. The risk of MDE was also positively associated with rural residency (OR 1.5, 95% CI 1.4-1.7), low income (OR 2.3, 95% CI 2.1-2.4), living alone (OR 2.6, 95% CI 2.3-3.0), smoking (OR 1.4, 95% CI 1.3-1.6) and certain other mental disorders (e.g. anxiety, phobia). Similar, albeit weaker, associations were observed with depressive symptoms. Among those with MDE, about 15% sought medical help or took psychiatric medication, 15% reported having suicidal ideation and 6% reported attempting suicide. CONCLUSIONS Among Chinese adults, the patterns and correlates of MDE were generally consistent with those observed in the West. The low rates of seeking professional help and treatment highlight the great gap in mental health services in China.

Abstract
BACKGROUND Adequate risk stratification is critical for the management of the patients with primary biliary cholangitis (PBC). The UK-PBC and GLOBE scoring systems for prognosis of PBC have been proposed recently, but have not been validated in Asian population. AIM To validate the UK-PBC and GLOBE scoring systems in Chinese patients for prognosis of PBC. To clarify the role of anti-gp210 as a biomarker, and to investigate whether anti-gp210 could affect the prognostic values of UK-PBC and GLOBE scoring systems. METHODS We retrospectively analysed 276 patients with PBC evaluated between September 2004 and May 2016, including 133 anti-gp210+ and 143 anti-gp210- patients. RESULTS The 5-year adverse outcome-free survivals of anti-gp210+ vs. anti-gp210- patients were 70% and 85%, respectively (P = 0.005). Cirrhosis (P = 0.001), albumin level ≤40 g/L (P = 0.011) and platelet count ≤153 × 109 (P < 0.001) had a superimposition effect on anti-gp210 antibody as a risk factor. Furthermore, long-term prognoses were evaluated using the UK-PBC and GLOBE scores. For UK-PBC scoring system, the area under receiver operating characteristic curve (AUROC) was 0.924 for all patients with PBC (n = 223), 0.940 for anti-gp210+ patients (n = 110) and 0.888 for anti-gp210- patients (n = 113). For GLOBE scoring system, the area under receiver operating characteristic curve was 0.901 for all patients with PBC (n = 223), 0.924 for anti-gp210+ patients (n = 110) and 0.848 for anti-gp210- patients (n = 113). UK-PBC score >0.0578 (P < 0.001, HR: 32.736, 95% CI: 11.368-94.267) and GLOBE score <0.850 (P < 0.001, HR: 18.763, 95% CI: 7.968-44.180) were associated with poorer outcomes in the whole cohort. CONCLUSIONS The UK-PBC and GLOBE scoring systems were good 5-year prognostic predictors in Chinese patients with PBC, especially in anti-gp210+ patients. As a biomarker, anti-gp210 antibody was associated with a more severe cholestatic manifestation and a worse long-term prognosis. The anti-gp210 antibody could be added to further optimise the UK-PBC and GLOBE scoring systems.

Abstract
Objective: To evaluate the associations between body mass index (BMI) and both total and cause-specific mortality. Methods: After excluding participants with heart disease, stroke, cancer, chronic obstructive pulmonary disease, and diabetes at baseline study, 428 593 participants aged 30-79 in the China Kadoorie Biobank study were chosen for this study. Participants were categorized into 9 groups according to their BMI status. Cox regression analysis was used to estimate the hazard ratios (HRs) and 95% confidence intervals (CIs) of mortality on BMI. Results: Among 3 085 054 person-years of the follow-up program between 2004 and 2013 (median 7.2 years), a total of 7 862 men and 6 315 women died. After adjusting for known or potential confounders, an increased risks of all-cause deaths were shown among participants with a BMI less than 18.5 (HR=1.40, 95%CI: 1.31-1.50), between 18.5-20.4 (HR=1.11, 95%CI: 1.05-1.17), and more than 35.0 (HR=2.05, 95%CI: 1.60-2.61), when compared to those with BMI between 20.5-22.4. Ranges of BMI with lower risk of cause-specific mortality were: 18.5-23.9 for ischemic heart disease, <26.0 for cerebro-vascular disease, 26.0-34.9 for cancers, and 24.0-25.9 for respiratory diseases. Conclusions: In this large prospective study, both underweight and obesity were associated with the increased total and certain cause-specific mortality, which were independent from other risk factors of death. Programs related to extensive follow-up, thorough analysis BMI and the risks of incidence on major chronic diseases all need to be developed, in order to better understand the impact of BMI on human health.

Abstract
Objective: To examine the prospective associations between airflow obstruction and total and cause-specific mortality. Methods: The study was based on China Kadoorie Biobank, in which 199 099 men and 287 895 women aged 30-79 years at baseline survey were included after excluding those with heart disease, stroke and cancer. The Global Initiative on Obstructive Lung Disease (GOLD) guideline was used to classify airflow obstruction. Cox regression models were used to estimate adjusted HR and 95%CI. Results: During 3 494 079 person-years of follow-up between 2004 and 2013 (median 7.2 years), a total of 21 649 people died. Absolute mortality rates were 5.5, 9.9, 13.1, 32.4 and 63.3 deaths per 1 000 person-years for participants who had normal airflow, GOLD-1 to GOLD-4 airflow obstruction, respectively. After adjusting potential confounders, compared with participants with normal lung function, the HRs for death were 0.98 (95%CI: 0.88-1.09), 1.03 (95%CI: 0.97-1.09), 1.62 (95% CI: 1.53-1.73) and 2.83 (95% CI: 2.59-3.10) for those whose airflow obstruction were classified as GOLD-1 to GOLD-4, respectively. The airflow obstruction was also associated with increased risk for deaths due to ischemic heart disease, cerebrovascular disease and chronic obstructive pulmonary disease. Conclusion: Airflow obstruction is associated with total and certain cause-specific mortality, the higher the airflow obstruction degree is, the higher the death risk is.

Abstract
The purpose of this study was to evaluate the effect of a bi-annual professional application of acidulated phosphate fluoride (APF) foam on caries increment in the primary dentition over a two-year period in the People’s Republic of China. In a double-blind, cluster-randomized, placebo-controlled trial, 392 children aged 3–4 years from 15 classes were randomly assigned to two groups on a school class basis. The experimental group (8 classes) received a bi-annual APF foam application, and the control group (7 classes) received the placebo. The mean increment of dmfs in the experimental group was 24.2% lower than that in the control group (p < 0.05). The significant caries reduction was observed on approximal surfaces in the experimental group compared with the control group (p < 0.01), but there were no differences on occlusal surfaces (p > 0.05). A bi-annual professional application of APF foam was effective in reducing the increment of dental caries in the primary teeth.

Abstract
Objective: To explore the associations between age at menarche and diabetes in adult women. Methods: We analyzed the baseline data of 32 364 female participants who were aged 30-79 years and had been enrolled into China Kadoorie Biobank (CKB) study from Tongxiang, Zhejiang province. Multiple logistic regression analysis were used to investigate the putative associations after adjusting for potential confounders. Variables of menarche age and others were added to the logistic regression model to evaluate the multiplicative interaction, respectively. Results: The mean age of female participants was (51.42 ± 9.63) years. And 3.73% and 24.17% of them reported their menarche age, ≤12 years, ≥17 years, respectively. The prevalence of diabetes among them was 5.75%. Compared with those with menarche age ≤12 years, the OR(95%CI) of 15-16, 13-14 and ≤12 years group were 1.13(1.00-1.27), 1.29(1.12-1.49) and 1.68(1.31-2.15) after adjusting for age, socioeconomic status, family history, health behaviors, menopause status, BMI and waist circumference. No significant differences were found in multiplicative interaction on diabetes between menarche age and smoking, alcohol consumption, physical activity, obesity, etc. (P>0.05). Conclusions: Menarche age is associated with higher risk of diabetes in female adults. The earlier menarche age is the higher risk of diabetes. There are no multiplicative interaction on diabetes between menarche age and other adults factors.

Abstract
OBJECTIVE To investigate the associations of major depressive disorder with coronary heart disease (CHD) and stroke in Chinese adults aged 30-79 years. METHODS In 2004-2008, China Kadoorie Biobank was conducted in 10 geographically defined regions (5 urban and 5 rural) of China. A total number of 512 891 participants aged 30-79 years were recruited in the baseline survey. A laptop-based electronic questionnaire was administrated face-to-face by trained health workers, collecting the general demographic and socio-economic status, dietary and other lifestyle behaviours (e.g. smoking, alcohol drinking, physical activity), medical history and family history of common chronic diseases. Major depressive episodes (MDE) in the past 12 months were assessed with the World Health Organization composite international diagnostic interview-short form (CIDI-SF). The physical measurements included the heights and weights, which were used to calculate the body mass indexes (BMI).Chi squared and t test were used to compare the differences in participants characteristics according to their major depressive disorder. Logistic models were employed to estimate the odds ratios (OR) and 95% CI of their major depressive disorder with prevalent coronary heart disease and stroke. RESULTS Among the 512 891 participants, 3 281 (0.6%) showed an MDE in the preceding 12 months, 15 472 (3.0%) reported prevalent CHD, and 8 884 (1.7%) reported prevalent stroke. Major depressive disorder was significantly associated with an increased risk of CHD and risk of stroke. Age- and gender-adjusted ORs (95% CI) were 1.80 (1.53-2.12) for CHD and 2.53 (2.09-3.05) for stroke. The associations were significant after further adjustment for potential confounders, such as other socio-demographic status, smoking, alcohol drinking, physical activity, and BMI, prevalent hypertension, diabetes as well as family history of cardiovascular diseases (OR=1.83, 95% CI=1.54-2.18 for CHD; OR=2.19, 95% CI=1.79-2.69 for stroke). Moreover, gender significantly interacted with MDE on prevalent stroke (P for multiplicative interaction=0.013). The men with an MDE in the past 12 months had the highest risk of stroke in the joint analyses of gender and depression disorder (OR=5.02, 95% CI=3.70-6.82). CONCLUSION The findings from this large cross-sectional study suggest that the presence of MDE is a risk factor for both CHD and stroke in Chinese adults aged 30-79 years, but further prospective studies are warranted to validate the results.

Abstract
OBJECTIVE To investigate the prevalence and risk factors of hypertension among residents in Pengzhou city of Sichuan province. METHODS Among 20 townships in Pengzhou city of Sichuan Province, 14 townships were selected using a clustered sampling based on the economic level and distance. The registered residents in the selected townships aged 30-79 years were recruited for a comprehensive survey from 2004 to 2007. A total of 55 687 residents (21 315 males and 34 372 females) were selected based on a face to face questionnaire interview and physical examination; the patient group included 14 151 residents with hypertension and the control group had 41 536 residents without hypertension were selected. Multivariate logistic regression model was used to investigate the influence factors for hypertension. OR (95%CI) values were calculated. Different levels of risk exposure factors were transformed into the risk scores using a statistical model. RESULTS The prevalence rate of hypertension was 25.41% among residents aged 30 years or above in Pengzhou (14 151/55 687), 28.95% (6 170/21 315) for male residents and 23.22% (7 981/34 372) for female residents. Multivaraite logistic regression analysis showed that main risk factors for hypertension in male residents were age, low educational level, widower, low household income, no medical insurance, no fresh fruits intake, high body mass index (BMI), high waist to hip ratio, and low physical activity, which was less than 3 metabolic equivalent of task (MET) level, among which the highest three riskswere (not including the social demographic characteristics) BMI≥28 kg/m(2), waist to hip ratio ≥0.90, and not consuming fresh fruits. OR (95% CI) values for these three key factors were 3.74 (3.27-4.28), 1.34 (1.24-1.44), and 1.27 (1.14-1.41), respectively. The corresponding risk scores for these factors were 2.993, 1.102, and 1.237, respectively. Main risk factors for hypertension in female residents were age, working hours, no medical insurance, fewer number of family members, no fresh fruits intake, smoking, never drinking tea, no dairy products intake, high BMI, highwaist to hip ratio and low physical activity, among which the highest three risks were (not including the social demographic characteristics) BMI ≥28 kg/m(2), MET level, and waist to hip ratio ≥0.85. OR (95% CI) values for these three key factors were 3.30 (3.02-3.60), 1.35 (1.22-1.51), and 1.33 (1.23-1.44), respectively. The corresponding risk scores for these factors were 2.390, 1.263, and 1.051, respectively. CONCLUSION The prevalence rate of hypertension among the residents over 30 years of age in Pengzhou city was 25.41%. The main risk factors were age, not consuming fresh fruits, high BMI, high waist to hip ratio, and low MET level.

Abstract
STUDY DESIGN Randomized experimental study. OBJECTIVES The study aimed to investigate the therapeutic efficacy and molecular mechanisms of A-68930 in a rat model of spinal cord injury (SCI)-induced acute lung injury (ALI). SETTING China. METHODS The influences of A-68930 on the pulmonary edema, histological changes, proinflammatory cytokines levels, myeloperoxidase (MPO) activity and NLRP3 inflammasome protein expression were estimated. RESULTS SCI significantly promoted NLRP3 inflammasome activation, increased proinflammatory cytokine productions and MPO activity, and induced pulmonary edema and tissue damage in the SCI group as compared with the control group. A-68930 administration significantly inhibited NLRP3 inflammasome activation and reduced inflammatory cytokines levels and MPO activity. Moreover, A-68930 administration attenuated pulmonary edema and histopathology. CONCLUSION Our experimental findings indicated that A-68930 exhibited a protective effect on SCI-induced ALI by the alleviations of inflammatory response with the inhibition NLRP3 inflammasome activation 72 h post injury. The present study indicated that A-68930 could be a potentially efficient therapeutic strategy for the treatment of SCI-induced ALI.

Abstract
Mammalian tooth development is a precise and complicated procedure. Several signaling pathways, such as nuclear factor (NF)-κB and WNT, are key regulators of tooth development. Any disturbance of these signaling pathways can potentially affect or block normal tooth development, and presently, there are more than 150 syndromes and 80 genes known to be related to tooth agenesis. Clarifying the interaction and crosstalk among these genes will provide important information regarding the mechanisms underlying missing teeth. In the current review, we summarize recently published findings on genes related to isolated and syndromic tooth agenesis; most of these genes function as positive regulators of cell proliferation or negative regulators of cell differentiation and apoptosis. Furthermore, we explore the corresponding networks involving these genes in addition to their implications for the clinical management of tooth agenesis. We conclude that this requires further study to improve patients' quality of life in the future.

Abstract
Obesity is a strong determinant of blood pressure. Uncertainty remains, however, about which indices of adiposity most strongly predict blood pressure, particularly among those who were relatively lean, such as those from rural China. We analyzed cross-sectional data on 55 687 (38.3% men) participants aged 30–79 years who were enrolled into the China Kadoorie Biobank from a rural county in southwest of China during 2004–2008. Measured body mass index (BMI) and waist circumference (WC) were related to blood pressure in multivariable linear regression analyses. The overall mean values of BMI, WC, systolic blood pressure (SBP) and diastolic blood pressure (DBP) were 23.3 kg m−2, 78.0 cm, 129.2 mm Hg and 77.2 mm Hg, respectively. There was a strongly positive, and apparently linear, relationship of BMI and WC with blood pressure, with 1 s.d. higher BMI associated with 4.3/2.3 mm Hg higher SBP/DBP and 1 s.d. WC associated with 3.8/2.1 mm Hg (P<0.0001). Additional adjustment for WC only slightly attenuated the association of BMI with blood pressure, whereas additional adjustment for BMI almost completely eliminated the association of WC with blood pressure. Our findings suggest that in relatively lean Chinese adults, general adiposity is more strongly assciated with blood pressure than central adiposity.

Abstract
Semaphorin 4d (Sema4d) has been proposed as a novel target gene for the treatment of osteoporosis. Recently, we fabricated a site-specific bone-targeting system from polymeric nanoparticles that demonstrates an ability to prevent bone loss in an osteoporotic model by interfering with Sema4d gene expression using small interference RNA (siRNA) molecules. The aim of the present investigation was to determine the effects of this targeting system on the periodontium, an area of high bone turnover. We demonstrated, by single photon emission computed tomography, that intravenous injection of this molecule in ovariectomized Balb/C mice is able to target alveolar bone peaking 4 hr post-injection. We then compared, by histological analysis, the bone volume/total volume (BV/TV), alveolar bone height loss, immunohistochemical expression of Sema4d, and total number of osteoclasts in mandibular alveolar bone. Four treatment modalities were compared as follows: (1) sham-operated, (2) OVX-operated, (3) OVX+estrogen replacement therapy, and (4) OVX+siRNA-Sema4d animals. The results from the present study demonstrate that an osteoporotic condition significantly increases alveolar bone height loss, and that the therapeutic effects via bone-targeting systems featuring interference of Sema4d are able to partly counteract alveolar bone loss caused by osteoporosis. While the future therapeutic demand for the large number of patients suffering from osteoporosis faces many challenges, we demonstrate within the present study an effective drug-delivery moiety with anabolic effects on the bone remodeling cycle able to locate and target alveolar bone regeneration.

Abstract
AIMS To examine the relationship of self-reported diabetes, and of random blood glucose levels among individuals without known diabetes, with the prevalence of cardiovascular disease in Chinese adults. METHODS We examined cross-sectional data from the China Kadoorie Biobank of 0.5 million people aged 30-79 years recruited from 10 diverse regions of China in the period 2004-2008. Logistic regression was used to estimate the odds ratios of prevalent cardiovascular disease associated with self-reported diabetes, and with measured random blood glucose levels among participants with no history of diabetes, adjusting simultaneously for age, sex, area, education, smoking, alcohol, blood pressure and physical activity. RESULTS A total of 3.2% of participants had self-reported diabetes (men 2.9%; women 3.3%) and 2.8% had screen-detected diabetes (men 2.6%; women 2.8%), i.e. they had no self-reported history of diabetes but a blood glucose level suggestive of a diagnosis of diabetes. Compared with individuals without a history of diabetes, the odds ratios associated with self-reported diabetes were 2.18 (95% CI 2.06-2.30) and 1.88 (95% CI 1.75-2.01) for prevalent ischaemic heart disease and stroke/transient ischaemic attack, respectively. Among participants without self-reported diabetes there was a positive association between random blood glucose and ischaemic heart disease and stroke/transient ischaemic attack prevalence (P for trend <0.0001). Below the diabetic threshold (<11.1 mmol/l) each additional 1 mmol/l of random blood glucose was associated with 4% (95% CI 2-5%) and 5% (95% CI 3-7%) higher odds of prevalent ischaemic heart disease and stroke/transient ischaemic attack, respectively. CONCLUSIONS In this adult Chinese population, self-reported diabetes was associated with a doubling of the odds of prevalent cardiovascular disease. Below the threshold for diabetes there was still a modest, positive association between random blood glucose and prevalent cardiovascular disease.

Abstract
BACKGROUND Mutations in 6 genes have been identified as being part of the etiology of amelogenesis imperfecta (AI) with various phenotypes in an isolated condition. Among them the FAM83H gene is the major contributor to the etiology of AI with unknown function. OBJECTIVE This study aims to determine the phenotypic and molecular characterization of Chinese AI patients and to analyze the structure and function of the FAM83H protein. METHODS We enrolled 6 hypocalcified AI and 3 hypoplastic AI families from the Chinese population. Mutation analysis was performed by amplifying and sequencing all exons including intron-exon borders for FAM83H and ENAM genes. Structural modeling and function analysis on the FAM83H protein were carried out by bioinformatic processing. RESULTS No obvious anterior open bite was observed in all the investigated individuals. Five mutations (c.906T>G, c.924dupT, c.973C>T, c.1354C>T and c.2029C>T) in the C-terminal of the FAM83H gene were revealed, respectively, in 5 out of 6 hypocalcified AI families, and a splicing mutation c.534 + 1G>A in the ENAM gene was identified in 1 out of 3 hypoplastic AI families. Structural models of the N- and C-terminal regions of FAM83H were generated by homology modeling. The predicted structure of the FAM83H N-terminal shows resemblance to that of glycosyltransferases with GT-A folds, and the predicted structure of the FAM83H C-terminal possesses similarity to type I collagen protein. CONCLUSIONS To our knowledge, this is the first report of AI with specific molecular variations in families of Chinese descent. Our study provides new insights into the structure and function of the FAM83H protein.

Abstract
Mechanisms associated with the progression of simple steatosis to non-alcoholic fatty liver disease (NAFLD) remain undefined. Regulatory T cells (T(regs)) play a critical role in regulating inflammatory processes in non-alcoholic steatohepatitis (NASH) and because T helper type 17 (Th17) functionally oppose T(reg)-mediated responses, this study focused on characterizing the role of Th17 cells using a NAFLD mouse model. C57BL/6 mice were fed either a normal diet (ND) or high fat (HF) diet for 8 weeks. Mice in the HF group had a significantly higher frequency of liver Th17 cells compared to ND-fed mice. Neutralization of interleukin (IL)-17 in HF mice ameliorated lipopolysaccharide (LPS)-induced liver injury reflected by decreased serum alanine aminotransferase (ALT) levels and reduced inflammatory cell infiltrates in the liver. In vitro, HepG2 cells cultured in the presence of free fatty acids (FFA; oleic acid and palmitic acid) for 24 h and IL-17 developed steatosis via insulin-signalling pathway interference. IL-17 and FFAs synergized to induce IL-6 production by HepG2 cells and murine primary hepatocytes which, in combination with transforming growth factor (TGF-β), expanded Th17 cells. It is likely that a similar process occurs in NASH patients, as there were significant levels of IL-17(+) cell infiltrates in NASH patient livers. The hepatic expression of Th17 cell-related genes [retinoid-related orphan receptor gamma (ROR)γt, IL-17, IL-21 and IL-23] was also increased significantly in NASH patients compared to healthy controls. Th17 cells and IL-17 were associated with hepatic steatosis and proinflammatory response in NAFLD and facilitated the transition from simple steatosis to steatohepatitis. Strategies designed to alter the balance between Th17 cells and T(regs) should be explored as a means of preventing progression to NASH and advanced liver diseases in NAFLD patients.

Abstract
OBJECTIVES To describe the prevalence of non-carious cervical lesions (NCCLs) and to assess the relative affects of risk factors on NCCLs in middle-aged and elderly people in Hubei Province, China. DESIGN A sample of 2,160 adults, aged 35-44 years and 65-74 years and balanced by age, gender, and urbanization, participated in the cross sectional epidemiological survey. Non-carious cervical lesions were examined using a modified Tooth Wear Index. Data were collected based on structured questionnaires that assessed general information as well as oral health. RESULTS The prevalence of non-carious cervical lesions was 38.8% for 35-44-year-olds and 56.6% for 65-74-year-olds. The first premolars, canines, and second premolars showed the highest prevalence of lesions, while the second molars demonstrated the least. Several risk factors such as age (OR = 2.45, p < 0.001), location (OR = 1.68, p = 0.001), frequency of toothbrushing (OR = 1.33, p = 0.016), bruxism (OR = 1.37, p < 0.001), and family income (OR = 1.44, p < 0.001) were found to be associated with lesion occurrence. CONCLUSIONS The prevalence of non-carious cervical lesions was relatively high in the middle-aged and elderly persons in China and was also associated with socio-behavioural risk factors.
