Objective To assess iron bioavailability of three iron-biofortified maizes using an in vitro digestion/ Caco-2 cell culture model. Method Three maize varieties rich in iron (Zhongtie 2, 3 and 4) and two maize varieties with lower content of iron (Zhengda 818 and 619) were pulverized, and the content of iron and phosphorus in each maize variety was measured. After digestion the iron bioavailability per g food was determined by using Caco-2 cell ferritin formation per mg cell protein as indicator. Results The iron content (33.250 mg/kg), iron bioavailability and the iron bioavailability per g food of Zhongtie 2 maize was the highest among all varieties, but its phosphorus content was lower. The maize varieties with the next higher iron bioavailability were Zhongtie 3 and Zhengda 818, and the lowest was Zhengda 619. Conclusion Zhongtie 2 maize contained the hightest content and bioavailability of iron,so it was optimal to use for the following human trials.

Obesity is a health problem of great concern to the whole society. Numerous studies have shown that obesity can lead to changes in the types and numbers of immune cell subsets and immune molecules in visceral adipose tissues, and IL-33/ST2 plays a crucial role in maintaining immune homeostasis. This paper reviewed the regulatory effects of IL-33/ST2 on adipocytes and immune cells in adipose tissues, as well as the changes of IL-33 in adipose tissues and the whole body during obesity in recent years.

In the 42 nd and 44 th workshops of CSPEN-nutritional risk-undernutrition-support-outcome-cost effectiveness ratio (NUSOC) multi-center database collaboration group, Jens Kondrup and Henrik Rasmussen described again the application of NRS 2002, the evidence-based basis of NRS 2002 development and the methodology for prospective validation of clinical effectiveness. There is no gold standard for validation. They both considered that malnutrition could be identified as a score of 3 or more for impaired nutritional status in NRS 2002. Although NRS 2002 is simple and easy to be applied, it is not comprehensive enough for malnutrition diagnosis. ASPEN and ESPEN on-line published the Global Leadership (nutritional) Initiative on Malnutrition(GLIM)diagnosis criteria in September 2018. With the gradual implementation of medicare payment based on diagnosis related groups(DRG)in China, the nutritional risk and the malnutrition diagnosis with Chinese version of ICD-10 (2016) code should be recorded in the first page of the medical records. In this terminology interpretations, the terms of nutritional risk screening(NRS 2002.01.016)and malnutrition diagnosis (GLIM-phenotypic criteria 01.028, etiologic criteria 01.029) published in Parenteral and Enteral Nutrition Terminology 2019 are discussed based on the reports given by Kondrup and Rasmussen in Beijing and Zhengzhou.

BACKGROUNDS: Cardiovascular disease (CVD) remains the leading cause of deaths nationwide. However, little is understood about its temporal trend and corresponding influence on longevity improvements. We aimed to describe the updated tendency in CVD mortality and to quantify its impact on life expectancy (LE) increase in China. METHODS: All-cause mortality rates were calculated with population sizes from the National Bureau of Statistics and death counts from the National Health Commission. We estimated CVD mortality rates by allocating age- and sex-based mortality envelopes to each CVD subtype based on its proportion derived from the Disease Surveillance Points system. The probability of CVD premature deaths and LE were calculated with life tables and we adopted Arriaga's method to quantitate age- and cause-specific contributions to LE gains. RESULTS: During 2013 to 2018, the age-standardized mortality rate of CVD decreased from 289.69 (95% confidence interval [CI]: 289.03, 290.35)/100,000 to 272.37 (95%CI: 271.81, 272.94)/100,000, along with a decline in probability of CVD premature deaths from 9.05% (95%CI: 9.02%, 9.09%) to 8.13% (95%CI: 8.10%, 8.16%). The gap in CVD mortality across sexes expanded with more remarkable declines in females, especially for those aged 15 to 64 years. Among major subtypes, the probability of premature deaths from hemorrhage stroke declined fastest, while improvements of ischemic stroke and ischemic heart disease were limited, and there was an increase in stroke sequelae. LE in China reached 77.04 (95%CI: 76.96, 77.12) years in 2018 with an increase of 1.38 years from 2013. Of the total LE gains, 21.15% (0.29 years) were attributed to reductions of CVD mortality in the overall population, mostly driven by those aged >65 years. CONCLUSIONS The general process in reducing CVD mortality has contributed to longevity improvements in China. More attention should be paid to prevention and control of atherosclerotic CVD and stroke sequelae, especially for the elderly. Working-age males also deserve additional attention due to inadequate improvements.
