Background China faces a major increase in cardiovascular disease, yet there is limited population-based data on risk factors, particularly in children. Methods and Results Fasting blood samples, anthropometry and blood pressure were collected on 9,244 children and adults aged ≥7 years in late 2009 as part of the national China Health and Nutrition Survey. Prevalent overweight, elevated blood pressure, and cardiometabolic risk factors: glucose, HbA1c, triglycerides (TG), total cholesterol (TC), high and low density lipoprotein cholesterol (HDL-C and LDL-C), and C-reactive protein (CRP) are presented. Results 11% of Chinese children and 30% of Chinese adults are overweight. Rates of diabetes, dyslipidemia, hypertension, and inflammation are high and increased with age and were associated with urbanization. Approximately 42% of children have at least one of the following: pre-diabetes or diabetes, hypertension, high TC, LDL-C, TG, and CRP and low HDL-C, as do 70% males and 60% females aged 18–40 years and >86% of males and females ≥40 years. Conclusions HbA1c findings suggest that as many as 29.4 million Chinese children and 415.8 million Chinese adults may be prediabetic or diabetic. The high prevalence in less urban areas and across all income levels suggests that cardiometabolic risk is pervasive across rural and urban China.

ObjectiveIncreasing evidence supports reciprocal communication between the enteric and the central nervous system in disease, termed the ‘gut–brain axis’. Recent findings suggest a connection between IBD and development of Parkinson’s disease. The role of IBD in dementia, another insidious neurodegenerative disorder, has not been explored.DesignUsing the Taiwanese National Health Insurance Research Database, we performed comparative analysis of 1742 patients with IBD ≥45 years old against 17 420 controls to assess dementia risk following IBD diagnosis. Controls were matched on bases of sex, access to healthcare, income and dementia-related comorbidities. All individuals were followed for dementia diagnosis for up to 16 years. Subanalyses included the relationship between sex, ulcerative colitis (UC) and Crohn’s disease (CD), and dementia risk.ResultsOverall incidence of dementia among patients with IBD was significantly elevated (5.5% vs 1.4% among controls). Patients with IBD were diagnosed with dementia at 76.24 years old on average, compared with 83.45 among controls. The HR of developing dementia among patients with IBD was 2.54 (95% CI 1.91 to 3.37). Among dementia types, the risk of developing Alzheimer’s dementia demonstrated the greatest increase. Dementia risk did not differ between sex differences nor UC versus CD.ConclusionThis population-based cohort study demonstrates significant association between IBD and subsequent development of dementia. Dementia was diagnosed at an earlier age among patients with IBD, and disease risk appeared to increase with IBD chronicity. These findings highlight the need for future research to elucidate the relationship between IBD and dementia.

Xanthomonas oryzae pv. oryzicola, the cause of bacterial leaf streak in rice, possesses clusters of hrp genes that determine its ability to elicit a hypersensitive response (HR) in nonhost tobacco and pathogenicity in host rice. A 27-kb region of the genome of X. oryzae pv. oryzicola (RS105) was identified and sequenced, revealing 10 hrp, 9 hrc (hrp conserved), and 8 hpa (hrp-associated) genes and 7 regulatory plant-inducible promoter boxes. While the region from hpa2 to hpaB and the hrpF operon resembled the corresponding genes of other xanthomonads, the hpaB-hrpF region incorporated an hrpE3 gene that was not present in X. oryzae pv. oryzae. We found that an hrpF mutant had lost the ability to elicit the HR in tobacco and pathogenicity in adult rice plants but still caused water-soaking symptoms in rice seedlings and that Hpa1 is an HR elicitor in nonhost tobacco whose expression is controlled by an hrp regulator, HrpX. Using an Hrp phenotype complementation test, we identified a small hrp cluster containing the hrpG and hrpX regulatory genes, which is separated from the core hrp cluster. In addition, we identified a gene, prhA (plant-regulated hrp), that played a key role in the Hrp phenotype of X. oryzae pv. oryzicola but was neither in the core hrp cluster nor in the hrp regulatory cluster. A prhA mutant failed to reduce the HR in tobacco and pathogenicity in rice but caused water-soaking symptoms in rice. This is the first report that X. oryzae pv. oryzicola possesses three separate DNA regions for HR induction in nonhost tobacco and pathogenicity in host rice, which will provide a fundamental base to understand pathogenicity determinants of X. oryzae pv. oryzicola compared with those of X. oryzae pv. oryzae.The interaction of many gram-negative plant-pathogenic bacteria with plants is modulated by two sets of genes: the avirulence (avr) or virulence (vir) genes determine host specificity via gene-for-gene interactions, and the hrp genes, which are usually clustered in a chromosomal region that spans 20 to 30 kb, are involved in induction of the hypersensitive response (HR) in resistant host and nonhost plants and pathogenicity in susceptible host plants (2, 7). HR is a rapid, local, programmed cell death that is induced upon recognition of the pathogen and concomitant with the inhibition of pathogen growth within the infected plants. Commonly, the nine hrp genes, which are highly conserved in plant and animal bacterial pathogens, are known as the hrc (hrp conserved) genes (6). The hrc genes encode the type III secretion system (TTSS) and are critical for pathogenicity and initiation of disease (2, 34). Recently, it was established that the hrpF gene in plant-pathogenic bacteria encodes a translocon that is a component of the TTSS (13,31,49). These hrc genes are also found in animal pathogens such as Salmonella and Shigella and are thought to be evolutionarily related to the flagellar apparatus (18,19,20). The hpa (hrpassociated) genes contribute to pathogenicity and to the induction of the HR in nonhost p...

Since the Opening of China, the country's economy has continuously and rapidly improved. Various economic, educational, and health policies have been implemented to shape the development of society, which may have greatly affected the Chinese diet and related malnutrition issues. The objective of the present review was to comprehensively review long-term trends in dietary intakes, nutrition status, and subsequent health challenges among Chinese adults. The data sources were
