Abstract
Objective: To analyze probability of prodromal Parkinson's disease (pPD) and assess the association between global cognitive function and cognitive domain function and probability of pPD in ≥55 years old middle-aged and elderly people in Hebei, Zhejiang, Shaanxi and Hunan Provinces in China. Methods: Data were collected from dataset of the Community-based Cohort Study on Nervous System Disease 2020. We selected 4 634 Alzheimer disease and Parkinson's disease free persons aged ≥55 years with completed information on demographics, disease history, cognitive test, and risk factors of Parkinson's disease for this study. Cognitive function was assessed using Montreal Cognitive Assessment Scale (Chinese version). Calculation of probability of pPD and assessment of possible/probable pPD were performed according to the criteria published by the International Parkinson and Movement Disorder Society. Multivariate linear regression model was used to analyze the association between cognitive function and probability of pPD. Results: The M (Q1,Q3) of global cognitive function and cognitive domains in terms of memory, execution, visuospatial function, language, attention and orientation were 25 (20, 30), 13 (11, 15), 10 (7, 12), 6 (4, 7), 5 (4, 6), 15 (12, 18) and 6 (6, 6) points, respectively. The M(Q1,Q3) of probability of pPD was 0.42% (0.80%, 1.73%), and the proportion of the study subjects with possible/probable pPD was 0.4%. Differences in the distribution of probability of pPD were significant among groups by total cognitive score quartiles (P<0.001), and the difference in proportions of study subjects with possible/probable pPD was significant and showed decline trend (P=0.001). After adjusted for confounders, the results of multivariate linear regression analyses showed that probability of pPD in the Q2, Q3 and Q4 group decreased by 23.4%, 31.2% and 20.1% compared with Q1 group, and corresponding β values were 0.766 (95%CI: 0.702-0.836), 0.688 (95%CI: 0.631-0.751) and 0.799 (95%CI: 0.730-0.875), respectively, the trend was significant (P<0.001). Higher index scores of execution, visuospatial function, language, attention and orientation were highly related to lower probability of pPD (P<0.001). Conclusion: Declines in global cognitive function and cognitive domains of execution, visuospatial function, language, attention and orientation might increase the probability of pPD in middle-aged and elderly people, suggesting the importance of cognitive intervention in early stage for pPD prevention.

Abstract
Objective: This study aimed to investigate the epidemiological characteristics of cardio-metabolic risk factors among children and adolescents aged 7-17 years in (Hebei, Zhejiang, Shaanxi, Hunan) 4 provinces of China and the influence of demographic and economic characteristics on them. Methods: A total of 1 747 children and adolescents aged 7-17 from a Community-based Cohort Study on Nervous System Disease in 2018 were selected. High waist circumference, central obesity, elevated TG, elevated TC, elevated LDL-C, decreased HDL-C, elevated blood pressure, elevated blood glucose, and clustering of risk factors was analyzed. χ2 test was used for univariate analysis, multivariate logistic regression was used to analyze the correlation between demographic and economic factors and risk factors, and the Cochran-Armitage trend test was used for trend analysis. Results: The detection rates of high waist circumference, decreased HDL-C, elevated blood pressure, elevated TG, elevated blood glucose, central obesity, elevated TC, and elevated LDL-C were 29.08%, 15.28%, 13.17%, 13.05%, 11.79%, 7.33%, 6.53%, and 5.15%, respectively. The rate of clustering of risk factors was 18.37%. Multivariate logistic regression analysis showed that the risk of high waist circumference in girls was higher than that in boys (OR=1.67, 95%CI: 1.26-2.22), and the risk of elevated blood glucose and clustering of risk factors was lower than that in boys (OR=0.69, 95%CI: 0.49-0.99; OR=0.72, 95%CI: 0.53-0.99). The risk of high waist circumference, decreased HDL-C, and clustering of risk factors in 13-17 years old group was higher than that in the 7-year-olds group (OR=2.24, 95%CI: 1.65-3.04; OR=1.59, 95%CI: 1.20-2.11; OR=1.75, 95%CI: 1.26-2.44), but the risk of central obesity was lower (OR=0.54, 95%CI: 0.37-0.78). The risk of elevated TC, elevated TG, and decreased HDL-C in children and adolescents in southern was higher than that in northern parts of China (OR=1.88, 95%CI: 1.25-2.83; OR=1.61, 95%CI: 1.17-2.22; OR=1.55, 95%CI: 1.19-2.04), but the risk of high waist circumference and central obesity was lower than that in northern China (OR=0.57, 95%CI: 0.43-0.75; OR=0.62, 95%CI: 0.42-0.90). The risk of decreased HDL-C in rural children and adolescents was higher than in urban children and adolescents (OR=1.36, 95%CI: 1.02-1.83). The risk of multiple risk factors increased with the increase in average monthly household income per capita and BMI level. Conclusions: High waist circumference, decreased HDL-C and elevated blood pressure were prominent cardio-metabolic risk factors among children and adolescents aged 7-17 years in 4 provinces of China in 2018. The region, average monthly household income per capita, and BMI were the main influencing factors of cardio-metabolic risk factors.

Transgenerational associations of parental famine exposure in early life with offspring risk of adult obesity in China. Obesity (Silver Spring) 2023; 31:279-289. [PMID: 36507560 DOI: 10.1002/oby.23593] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/28/2022] [Revised: 08/08/2022] [Accepted: 08/31/2022] [Indexed: 12/14/2022]
Abstract
OBJECTIVE The aim of this study was to investigate the transgenerational associations between exposure to famine in early life and obesity. METHODS This study used the longitudinal data from the China Health and Nutrition Survey from 1989 to 2015. A total of 1113 fathers and 1207 mothers (946 mother-father pairs) born in 1955 to 1966 and 1895 adult offspring were included. Offspring were classified into subgroups according to the famine exposure of their parents (unexposed, maternal exposed, paternal exposed, parental exposed) and exposure timing (during fetal development, childhood). RESULTS Maternal exposure to famine in early life was associated with elevated levels of BMI, waist circumference, overweight, and central obesity of their children, whereas paternal exposure was inversely associated with these measurements. Compared with children of unexposed parents (P0M0), the maternal exposed group (P0M1) had higher mean BMI, by 1.3 kg/m2 (95% CI: 0.3 to 2.4); waist circumference, by 1.5 cm (-1.0 to 3.9); overweight (odds ratio [OR] [95% CI]: 3.1 [1.6 to 6.1]); and central obesity (OR [95% CI]: 1.9 [1.02 to 3.7]). No significant heterogeneity was observed in the associations by sex of offspring. CONCLUSIONS Fetal and early childhood exposure to famine in parents may be associated with their children's risk of obesity during adulthood. A better understanding of the transgenerational associations is important for developing strategies to reduce obesity risk in future generations.

Abstract
Objective: To analyze the association of fasting plasma glucose (FPG) with mild cognitive impairment (MCI) in the Chinese middle-aged and elderly population from four provinces. Methods: Data were drawn from the baseline data of the Community-based Cohort Study on Nervous System Disease 2018-2019. We selected 3 272 subjects aged 55 and above with completed information on demographics, lifestyle, disease history, cognitive test, psychological assessment, and bio-chemistries measurement, and who were capable of performing basic activities of daily living but without Alzheimer's disease during recruitment. A multivariate logistic regression model was employed to analyze the association between FPG and MCI. Results: Median level of FPG in the study population was 5.5 mmol/L. The prevalence of MCI was 24.8%, and those in groups of the FPG quintile were 19.4%, 22.2%, 29.2%, 26.6%, and 26.1%, respectively, which significantly increased the trend (P=0.002). After adjustment of confounders, multivariate logistic regression analysis found that the MCI risk of subjects in the Q3,Q4 and Q5 groups was 1.641 (95%CI: 1.226-2.131), 1.373 (95%CI: 1.036-1.825), 1.402 (95%CI: 1.054-1.871) times as high as that in the Q1 group, respectively. Conclusion: High FPG level might serve as a risk factor for MCI in the middle-aged and elderly population, suggesting the importance of monitoring and controlling plasma glucose even without diabetes.

Abstract
Objective: To analyze the association between different types of obesity, BMI, and waist circumference (WC) and the risk of type 2 diabetes mellitus (T2DM) in Chinese adults. Methods: Based on the China Health and Nutrition Survey data in 2018, different types of obesity were defined across different BMI and WC combinations based on Criteria of weight for adults (WS/T 428-2013), including non-obesity, simple general obesity, simple central obesity, and complex obesity. The associations of different types of obesity, BMI, and WC with T2DM risk were explored using two-level mixed-effects logistic regression and restricted cubic spline models. Results: A total of 7 030 subjects aged 18-65 were included in this study. The prevalence of general obesity and central obesity were 16.29% (502/3 082), 42.28% (1 303/3 082) in males, and 14.41% (569/3 948), 37.87% (1 495/3 948) in females. The prevalence of complex obesity was 14.70% and 12.97% in males and females, respectively. The prevalence of T2DM was 11.28% in participants, and the prevalence in complex obesity (18.98%, 22.07%) was higher than in simple central obesity (16.24%, 15.26%) and non-obesity (9.65%, 5.18%) in males and females, respectively. Multilevel regressions showed that males with simple central obesity and complex obesity had 1.61 (95%CI: 1.24-2.08) and 2.11 (95%CI: 1.56-2.86) times the odds of T2DM, respectively, as compared with the non-obesity; and the odds of T2DM in females were 2.70 (95%CI: 1.16-6.28) times for simple general obesity, 2.62 (95%CI: 2.01-3.40) times for simple central obesity, and 4.47 (95%CI: 3.35-5.98) times for complex obesity. A nearly linear positive association was observed between BMI and T2DM risk. WC was also positively associated with T2DM risk and a non-linearly increased risk in females (P for non-linear=0.024). The risk of T2DM increased when BMI ≥22.5 kg/m2 and 23.0 kg/m2, WC ≥85.0 cm and 80.0 cm in males and females, respectively. Conclusions: Complex obesity adults are more likely to suffer from T2DM. The risk of T2DM increases significantly when BMI is at the normal high values and waist circumference at the stage of pre-central obesity.

Abstract
Objective: To investigate the epidemiological characteristics and trends of cardiometabolic risk factors in residents aged 18-64 years in 15 provinces (autonomous regions,municipalities) of China, and to analyze the impact of demographic characteristics on cardiometabolic risk factors. Methods: 19 827 adults aged 18-64 from the "China Health and Nutrition Survey" in 2009, 2015 and 2018 were selected as subjects. Using the data of demographic and economic factors, blood biochemical measurements and physical measurements, the trend of detection rates of metabolic risk factors in different years was analyzed by Joinpoint regression model. The association between risk factors and demographic characteristics was analyzed by multinomial logit model. Results: Among all the risk factors, overweight and central obesity had the highest detection rates (36.41% and 39.93%, respectively). In addition, among the three years, the clustering of risk factors was highest in 2015 and decreased slightly in 2018. Joinpoint regression model analysis showed that the detection rates of most metabolic risk factors expressing an overall upward trend from 2009 to 2018 but there was no significantly statistical difference in annual percentage change (APC). Among the risk factors under APC>0, the APC of obesity and diabetes was the largest (APC=5.37%, t=3.26, P=0.190; APC=5.52%, t=7.70, P=0.082), while among the risk factors with APC<0, high hs-CRP appeared as the largest (APC=-6.95%, t=-4.17, P=0.150). Multinomial logit model showed that male had higher risk of developing all metabolic risk factors than female except LDL-C, TC and hs-CRP. The risk of other risk factors except HDL-C in adults aged 45-64 years was higher than that in the younger age group aged 18-44 years, and was more significant in hypertension and elevated HbA1c, which were 4.67 (95%CI:4.07-5.37) times and 3.73 (95%CI:2.91-4.77) times of the younger age group, respectively. Residents living in the eastern areas had the highest risk of obesity, borderline high LDL-C, hypertension, elevated blood glucose and diabetes, and the lowest risk of elevated TG and high hs-CRP. People from the western region had the lowest risk of central obesity, elevated blood pressure and hypertension. Conclusions: In the three years, the detection rate and clustering of most risk factors were the highest in 2015, and there was little change in 2018. Gender, age and geographical distribution were the main influencing factors of cadiometabolic risk factors. It is suggested to adopt targeted prevention strategies and intervention measures to reduce the risk of cardiovascular disease.

Abstract
AIM To investigate the diagnostic value of quantitative susceptibility mapping (QSM) in mild cognitive impairment (MCI) of aluminium (Al) workers. MATERIALS AND METHODS The basic data of 53 workers in an Al factory were collected and divided into the MCI group and normal control (NC) group by Montreal Cognitive Assessment (MoCA) scores. All participants were tested for plasma Al concentration and had magnetic resonance imaging (MRI). The QSM values of many areas of the brain were delineated and measured. Independent two-sample t-tests or non-parametric tests were used to compare the parameter values between the two groups. Spearman's correlation analysis was performed between QSM values, MoCA scores, and plasma Al concentration. The receiver operating characteristic curve and z test were performed to assess diagnostic efficacy and the best parameter. RESULTS There was no difference in age and educational level. Plasma Al concentration of the MCI group was higher than that of NC group (p=0.057). QSM values of the left hippocampus, left dentate nucleus, right substantia nigra, and left putamen in MCI group were higher than that of NC group (p<0.05), and the left hippocampus had the best diagnostic efficacy. QSM values correlated negatively with MoCA scores. No correlation was found between QSM values and plasma Al concentration (p>0.05). CONCLUSION QSM might be a neuroimaging marker for the diagnosis of MCI. The left hippocampus showed the best diagnostic efficacy. Plasma Al concentration of the MCI group was higher than that of the NC group. A correlation between QSM and plasma Al concentration was not found.

Abstract
The rechargeability of the lithium anode in lithium-sulfur (Li-S) batteries is an issue for this type of battery. In this work, we demonstrate a Li-S full battery comprising a protected anode scaffold and a Li2S cathode. The stabilized performance is attained by an on-site fluorination strategy, using BiF3 for the interfacial coating of the anode. Unlike previously reported LiF protective coating derived from the vapor/solution depositions, BiF3 nanocrystals would be lithiated on-site to the anode surface and server as the protective layer. The chemically inertial Li3Bi alloy can provide additional ion-conductive paths and stitch the LiF to form a seamless protective layer, thereby suppressing the dendrite propagation and parasitic reactions effectively. With the designed anode structures and compositions, the high-loading full battery (8.05 mg cm-2) can achieve an exceptional utilization of both sulfur (898 mAh gS-1) and lithium (1533 mAh gLi-1) over 200 cycles, marking a step toward cyclable Li metal batteries at a high capacity.

Abstract
BACKGROUND Elevated temperature as a result of global climate warming, either in form of sudden heatwave (heat shock) or prolonged warming, has profound effects on the growth and development of plants. However, how plants differentially respond to these two forms of elevated temperatures is largely unknown. Here we have therefore performed a comprehensive comparison of multi-level responses of Arabidopsis leaves to heat shock and prolonged warming. RESULTS The plant responded to prolonged warming through decreased stomatal conductance, and to heat shock by increased transpiration. In carbon metabolism, the glycolysis pathway was enhanced while the tricarboxylic acid (TCA) cycle was inhibited under prolonged warming, and heat shock significantly limited the conversion of pyruvate into acetyl coenzyme A. The cellular concentration of hydrogen peroxide (H2O2) and the activities of antioxidant enzymes were increased under both conditions but exhibited a higher induction under heat shock. Interestingly, the transcription factors, class A1 heat shock factors (HSFA1s) and dehydration responsive element-binding proteins (DREBs), were up-regulated under heat shock, whereas with prolonged warming, other abiotic stress response pathways, especially basic leucine zipper factors (bZIPs) were up-regulated instead. CONCLUSIONS Our findings reveal that Arabidopsis exhibits different response patterns under heat shock versus prolonged warming, and plants employ distinctly different response strategies to combat these two types of thermal stress.

Abstract
Objective: To analyze the prevalence, co-prevalence of cardiovascular metabolic (CM) risk factors in women aged 15-49 years in China, and describe the influence of social economic factors on them. Methods: The project data of Nutritional Status and Health Transition of Chinese Residents in 2015 were used. The changes in epidemiological characteristics of central obesity, elevated blood pressure, FPG and TG, decreased HDL-C and co-prevalence of the risk factors in women aged 15-49 years were analyzed. According to the definition of the metabolic syndrome released by the International Diabetes Federation in 2005, five cardio-metabolic risk factors appeared as central obesity, increased triglycerides, decreased HDL-C, increased blood pressure and increased plasma glucose. Co-prevalence of risk factors was defined as detecting 2 or more risk factors in a person at the same time. Multivariate logistic regression model was used to analyze the relationship between socioeconomic factors and metabolic risk factors. Results: In 2015, in women aged 15-49 years in 15 provinces, the detection number (rates) of central obesity, elevated blood pressure, FPG and TG, decreased HDL-C, at least one CM risk factor and co-detection rate of CM risk factors were 944 (47.4%), 464 (23.3%), 123 (6.2%), 327 (16.4%), 1 025 (51.5%), 1 501 (75.4%), and 874 (43.9%), respectively. Compared with women aged 15-19 years, the women in age group of 25-, 30-, 35-, 40-, and 45-49 years were more likely to have central obesity (P<0.05), the women in age group of 30- 35-, 40-, and 45-49 years were more likely to have elevated blood pressure (P<0.05), the women aged 45-49 years were more likely to be affected by one or more CM risk factors (P<0.05), but the women in age group 25-29 years group had lower risk for elevated FPG (P<0.05). The odds of having central obesity, elevated blood pressure, FPG and TG, decreased HDL-C, at least one CM risk factor and co-prevalence of CM risk factors in women with BMI≥24.0 kg/m(2) were 14.16, 3.05, 2.46, 2.49, 2.42, 9.79 and 7.39 times higher than those in the women with BMI of 18.5-24.0 kg/m(2), respectively. The odds of having elevated FPG and TG in women aged 15-49 years in western China and the odds of having elevated blood pressure and FPG in women aged 15-49 years in eastern China were significantly higher than those in central China. No significant correlations were found between the prevalence and co-prevalence of CM risk factors and income level or urban and rural area residences in women aged 15-49 years. Conclusions: Age, BMI level and living area were the major influencing CM risk factors. The precise prevention and control measures should be taken in time for the adverse changes in CM risk factor prevalence.

Abstract
Objective: To analyze the status of dietary sodium intake of Chinese adult residents in fifteen provinces in 2015. Methods: Data were collected from 2015 China Nutrition Transition Cohort Study. This cohort study used a three consecutive 24-h retrospective method to record food intake and weighing method to record household condiment consumption. In this study, 14 847 residents aged 18 years and over with complete data from 15 provinces in 2015 were selected for the comparison of dietary sodium intake (median) with different characteristics. Results: Among the 14 847 residents, 47.1% were males, and the rural and northern residents accounted for 60.1% and 37.7%, respectively. Median sodium intake was 3 960.0 mg/d among residents in 2015. The sodium intake of males (4 272.1 mg/d) was higher than that of females (3 716.6 mg/d). Across age subgroups, sodium intake was highest among residents aged 45-59 years (4 257.0 mg/d; 18-44 years old, 3 867.1 mg/d; ≥60 years old, 3 799.0 mg/d). Sodium intake was higher in rural area (4 042.9 mg/d) than in urban area (3 866.8 mg/d), higher in north (4 229.2 mg/d) than in south (3 806.8 mg/d) (all P values <0.05). 11.8% of residents with dietary sodium intake were below 2 000 mg/d. The main sources of dietary sodium were condiments (79.4%), regular cooking foods (11.9%) and processed foods (8.7%). Among the condiments, the salt and soy sauce accounted for 63.6% and 10.4%, respectively. Conclusion: In 2015, Chinese adult residents had higher dietary sodium intake with gender and regional differences. Condiments were the main source of dietary sodium.

Abstract
A rechargeable lithium anode requires a porous structure for a high capacity, and a stable electrode/electrolyte interface against dendrite formation and polysulfide crossover when used in a lithium-sulfur battery. Here, we design two simple steps of spontaneous reactions for protecting porous lithium electrodes. First, a reaction between molten lithium and sulfur-impregnated carbon nanofiber forms a fibrous network with a lithium shell and a carbon core. Second, we coat the surface of this porous lithium electrode with a composite of lithium bismuth alloys and lithium fluoride through another spontaneous reaction between lithium and bismuth trifluoride, solvated with phosphorous pentasulfide, which also polymerizes with lithium sulfide residual in the electrode to form a solid electrolyte layer. This protected porous lithium electrode enables stable operation of a lithium-sulfur battery with a sulfur loading of 10.2 mg cm-2 at 6.0 mA cm-2 for 200 cycles.

Abstract
OBJECTIVE To study clinical effects of needle Dao for the treatment of carpal tunnel syndrome. METHODS From July 2014 to December 2016, 60 patients with carpal tunnel syndrome were divided into two groups: needle Dao treatment group(treatment group), and brace and medicine treatment group(control group), 30 cases in each group. There were 8 males and 22 females in the treatment group, with an average age of (49.38±7.43) years old. There were 7 males and 23 females in the control group, with an average age of (50.23±8.71) years old. There were no statistically significant differences between two groups before treatment in age, sex, course of disease, sensory nerve conduction velocity (SCV), sensory nerve action potential (SNAP), and distal motor latency(DML). The patients in the treatment group were treated with needle Dao for 1 to 2 times, while the patients in the control group were given celecoxib, vitamin B1 and vitamin B12, with the brace fixed. After treatment, the changes of SCV, SNAP and DML in two groups were observed. RESULTS After treatment, the SCV were (48.63±7.33) m/s and (41.24±6.15) m/s in treatment group and control group separately, the SNAP were (9.89±3.71) m/s and (8.22±2.19) m/s, and the DML were(5.11±2.28) m/s and (6.13±2.23) m/s. The SCV, SNAP and DML after treatment were better than those before treatment(P<0.05). And the results of SCV, SNAP and DML of patients in the treatment group were better than those of patients in the control group(P<0.001). CONCLUSIONS Needle Dao can effectively improve the overall treatment efficiency of patients with carpal tunnel syndrome and reduce the symptoms of patients, which is feasible and suitable to use in clinical.

Abstract
Intramuscular fat (IMF) content and fatty acid (FA) composition vary significantly across beef cattle breeds, which play an important role in taste and nutritional value. However, the molecular mechanisms underlying these phenotypic differences remain unknown. The present study compared meat quality traits between Yunling cattle and Chinese Simmental cattle. Yunling cattle showed a lower IMF content and proportion of monounsaturated fatty acids (MUFA), as well as higher proportions of saturated fatty acids (SFA), polyunsaturated fatty acids (PUFA), and short-chain fatty acids (sc-FA) in the longissimus dorsi (LD) muscle than Chinese Simmental cattle. To further identify the candidate genes and pathways responsible for these phenotypic differences, the transcriptome of LD muscle from the two breeds were measured using RNA-seq. A total of 1347 differentially expressed genes were identified. The major metabolic pathways that were differentially modulated were lipolysis and glycometabolism. Yunling cattle showed a higher expression of lipolysis genes (ALDH9A1, ACSL5, ACADM, ACAT2, ACOT2) and a lower expression of genes related to glycometabolism (PGM1, GALM, PGM1, GPI, LDHA). This research identified candidate genes and pathways for IMF content and FA composition in the LD muscle of beef cattle, which may facilitate the design of new selection strategies to improve meat quality.

Treatment efficiency and stability of skeletal Class III malocclusion with a surgery-first approach. Orthod Craniofac Res 2018; 21:90-95. [PMID: 29493904 DOI: 10.1111/ocr.12221] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 01/30/2018] [Indexed: 10/17/2022]
Abstract
OBJECTIVES To compare treatment duration in skeletal Class III malocclusion patients managed with a 2-step treatment (surgery-first approach, SFA) and conventional 3-step treatment, and to compare stability of surgical outcomes between segmentation and non-segmentation in the 2-step treatment group. SETTING AND SAMPLE POPULATION The sample population consisted of 37 patients who completed orthognathic surgery (OGS) and orthodontic correction at the Charm Aesthetic Surgery Clinic (Taipei, Taiwan) between 2012 and 2015. Of these, 26 received 2-step treatment and 11 received 3-step treatment. MATERIALS AND METHODS To compare treatment efficiency and stability, three time points were analysed: T0 , before treatment (before OGS in the 2-step group and before orthodontic treatment in the 3-step group); T1 , after OGS but before orthodontic correction (cone beam computed tomography (CBCT) was obtained within 2 weeks of OGS); and T2 , after orthodontic correction (CBCT was obtained on the day of bracket removal). The post-OGS (T1 ) CBCT items were individually superimposed on the pre-treatment (T0 ) CBCT items to determine the distance of B point migration. RESULTS A significant difference was found in treatment times between 2-step treatment and conventional 3-step treatment. In addition, no significant difference was found when comparing B-X (mm) and B-Y (mm) at T2 -T1 for the segmentation and non-segmentation groups. CONCLUSIONS Using SFA for skeletal Class III malocclusions saves approximately 6 months of treatment time over 3-step treatment; the stability of the segmentation group was comparable to that of the non-segmentation group, a result that is possibly associated with the fixation of 2 miniplates.

Abstract
BACKGROUND/OBJECTIVES Several studies have suggested differential health effects in relation to different meat composition in Western population. The purpose of the study was to examine secular trends in meat and seafood consumption patterns among Chinese adults between 1991 and 2011. SUBJECTS/METHODS Our longitudinal data are from 21,144 adults aged 18-75 in the China Health and Nutrition Survey, prospective cohort study. We assessed the intakes of meat and subtypes with three 24-h dietary recalls. We conducted multilevel mixed-effect logistic and linear regression models to examine meat consumption dynamics. RESULTS The proportions of Chinese adults who consumed red meat, poultry and seafood increased from 65.7% in 1991 to 86.1% in 2011, from 7.5 to 20.9% and from 27.4 to 37.8%, respectively. With rapid decrease in meat intakes since 2009, the intakes of total meat, red meat, poultry and seafood among their consumers were 86.7 g/day, 86.4 g/day, 71.0 g/day and 70.3 g/day in 2011, respectively, which were just slightly higher compared with those in 1991. Fatty fresh pork has been predominantly component of total meat overtime, which consituted 54.0% of total meat intake, 80.0% of fresh red meat intake and 98.7% of fatty fresh red meat intake in 2011. CONCLUSION Over the past two decades, meat consumption patterns of Chinese adults have been characterized by having a predominant intake of fatty fresh pork, suboptimal intakes of seafood and increased proportion of adults having excessive intakes of red meat and poultry overtime.

Abstract
AIMS Nasal tolerance induction with autoantigens can effectively protect against a variety of experimental models of autoimmune disease. The aims of this study were to characterise the dosage and kinetics of inhibition of experimental autoimmune uveoretinitis (EAU) via intranasal administration of the uveitogenic antigen interphotoreceptor retinal binding protein (IRBP) in the murine model of IRBP induced EAU. METHODS B10RIII mice were tolerised by intranasal administration of IRBP either with a long term multiple low dose or a short term/high dosing regimen before subcutaneous immunisation with IRBP in complete Freund's adjuvant (CFA). On day 15 post-immunisation, mice were killed and eyes were removed for histological examination and quantification of inflammatory cell infiltration and degree of target organ (rod outer segment, ROS) destruction. RESULTS Nasal administration of multiple low doses of IRBP (1 microg or 3 microg IRBP per mouse per day for 10 days) significantly protected mice from IRBP induced EAU. Short term/high dose regimens were only effective when given either as a single or, at most, as two consecutive doses (40 microg per dose). Multiple doses in the range of 45-120 microg over 3 days afforded no protection. CONCLUSIONS These results indicate that both dose and frequency of intranasal antigen administration are pivotal to tolerance induction and subsequent suppression of T cell mediated autoimmune disease.

Abstract
PURPOSE Interleukin (IL)-18 has been described as a proinflammatory cytokine in rheumatoid arthritis and bacterial infectious diseases. The present study was designed to determine the role of IL-18 in a model of ocular experimental autoimmune uveitis (EAU). The initial studies were conducted to detect the expression of IL-18 in normal mouse eye tissue, and the later studies investigated induction of EAU in mice with an IL-18(-/-) phenotype. METHODS IL-18 detection was performed by using 5-bromo-4-chloro-3-indoyl-ss--D-galactopyranoside (X-Gal) staining on frozen sections of eyes from mice (129/CD1, DBA1, and Balb/c), either of normal phenotype (+/+) or of deficiency (+/-, -/-) in the IL-18 gene which had been replaced by introduced genes including LacZ under the control of an IL-18 promotor. Severity of EAU was assessed in DBA1 and 129/CD1 wild-type (WT) or IL-18 knockout (KO) mice after immunization with the uveitogenic antigen: interphotoreceptor retinal binding protein (IRBP) peptide 161-180. Lymphocyte proliferation and cytokine production were also measured in WT and IL-18 KO DBA1 mice 15 days after immunization. RESULTS IL-18 is constitutively expressed in the epithelial cells in iris, ciliary body, and retina. EAU-resistant mice (129/CD1) with an IL-18(-/-) phenotype remained resistant after immunization with IRBP peptide (P161-180). However, EAU-susceptible mice (DBA1) exhibited disease with similar histologic characteristics, despite a generalized reduction of interferon (IFN)-gamma and tumor necrosis factor (TNF)-alpha on an IL-18(-/-) phenotype. DBA1 IL-18(-/-) also demonstrated reduced IL-10 production. CONCLUSIONS The IL-18 gene is not necessary for the initiation or pathogenesis of EAU induced by IRBP peptide 161-180. IL-18 is expressed in the epithelial cells in iris, ciliary body, and retina in the eyes, but its role in the eye remains undetermined.

Abstract
PURPOSE To investigate the characteristics of the mononuclear cell infiltrate in murine experimental autoimmune uveoretinitis (EAU). METHODS EAU was induced by immunization with bovine interphotoreceptor retinal binding protein (IRBP) in Freund's complete adjuvant (subcutaneous injection) and pertussis toxin (intraperitoneal injection) in B10RIII mouse. Then animals were killed on days 7, 9, 12, 15, 20, 26, and 39 after immunization. Eyes were processed for hematoxylin and eosin staining to characterize the disease and to assess the severity and extent of the EAU. Single and dual immunohistochemical staining in various combinations with monoclonal antibodies against CD45, CD4, CD8, major histocompatibility complex (MHC) class II, CD11c, NLDC-145, and a variety of macrophage markers was performed. RESULTS The authors' results showed that vitritis, vasculitis and perivasculitis, retinal detachment, and granuloma formation in retina and choroid were the predominant features of IRBP-induced B10RIII mice EAU. Immunohistologic results showed that CD4+ T cells and macrophages were the main infiltrating cells in retina and choroid throughout the entire course of the disease. MHC class II negative macrophages expressing antigens reacting with MOMA-2, F4/80, sialoadhesin, and CD11b were prominent during the peak phase of tissue damage in the retina and choroid. Dendritic cells (DCs) characterized by dual positivity for MHC class II and CD11c and negative for sialoadhesin appeared at time of disease onset and continued to be recruited during the inflammatory process. DCs at the site of inflammation were NLDC-145 weak and CD8 negative, indicating that they were of the myeloid rather than the lymphoid lineage. CONCLUSIONS The results suggest that EAU in B10RIII mice is initiated by local-infiltrating, dendritic antigen-presenting cells, whereas tissue damage is associated with sialoadhesin-positive, phagocytic nonantigen-presenting macrophages during the effector stage.
