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.
