[Construction and acceptability of different complementary foods texture in infants and young children aged 6 to 23 months].

Objective: To construct the complementary food texture in infants and young children aged 6 to 23 months, and observe the acceptability of complementary food of different months old infants.

Methods: Based on the domestic and foreign guidelines, consensus and literatures on complementary feeding, and combined with the characteristics of children's growth and development in China. The complementary food texture index of 6-23 months old infants and young children was constructed.

[Conditional optimization and methodological evaluation of liquid protein microarray in detecting cystatin C].

Objective: To optimize the detection conditions and evaluate of cystatin C(CysC) by liquid protein microarray.

Methods: CysC was detected by double antibody sandwich method using liquid protein microarray. On the basis of determining the optimal concentration combination of captured antibody and detected antibody, the detection conditions were optimized by determining the biological detection limit and lower detection limit, drawing the S-shaped curve and judging the linear range, and establishing the standard curve and regression equation.

[Construction of malnutrition visualization system].

Objective: To establish a set of visualization systems suitable for displaying the transition of malnutrition status in different population across time and space in China.

Methods: Based on the data characteristics of the four monitoring systems, including the China Nutrition and Health Surveillance, the China Health and Nutrition Survey, the Project of Children Nutrition Improvement in Poor Rural Regions, and the Nutrition Improvement Program for Rural Compulsory Education Students, to be merged and the requirements of this project, the client/server architecture(C/S architecture) application mode was adopted, the Visual Studio 2019 development tool set, Python 3.7-10 and C # 8.

Spatial Distribution and Temporal Trends of Dietary Niacin Intake in Chinese Residents ≥ 5 Years of Age between 1991 and 2018.

Limited knowledge exists on trends in niacin consumption and the prevalence of inadequate intakes in China. Understanding trends and the spatial distribution of the prevalence of inadequate niacin intake is crucial to identifying high-risk areas and sub-populations. The dietary intakes of niacin between 1991 and 2018 were analyzed using the China Health and Nutrition Survey (CHNS) data.

Optimization and Application of A Bionic System of Dynamic Co-Culture with Hepatocytes and Renal Cells Based on Microfluidic Chip Technique in Evaluating Materials of Health Food.

We aimed to explore the optimization and application of a bionic system of dynamic co-culture with hepatocytes and renal cells based on the microfluidic chip technique in evaluating emodin, which might replace the conventionally cytological evaluation technique of health food. After optimal experiments, the improved bionic system was composed of human hepatocellular carcinoma cells (HepG2), human renal glomerular endothelial cells (HRGECs), rat tail collagen type I, and gelatin with optimized concentrations (1.3 mg/mL + 7.

[Optimization of platform conditions for simultaneous detection of multiple nutritional marker proteins by liquid protein microarray].

Objective: To optimize the technical conditions for simultaneous detection of serum ferritin(SF), soluble transferrin receptor(sTfR), C-reactive protein(CRP)and retinol-binding protein four(RBP4)by liquid protein microarray.

Methods: The trapping antibodies of the four proteins were coupled to magnetic beads with different codes, and the samples were added to the 96-well plate. The antibodies were detected by double antibody sandwich method.

[Current status of nutrition work in Chinese disease control institutions].

Objective: To investigate the basic nutrition working status in Chinese CDCs.

Methods: The questionnaire of nutritional working ability of CDC was designed for investigation. The questionnaire was filled in by all disease control institutions of 31 provinces, autonomous regions, municipalities and Xinjiang Production and Construction Corps(excluding Hong Kong, Macao and Taiwan).

[Study on infant and young children complementary feeding in poor rural regions in China].

Objective: To analyze complementary feeding status and issues among 6-23 month infants and young children(IYC) in poor rural regions in China to figure out actions further IYC nutrition in China.

Methods: Using 2018 monitoring data from Project of Children Nutrition Improvement in Poor Rural Regions, 6-23 months infants were sampled with the method of a combination of provincial stratification, multi-stage stratified cluster, PPS and random equidistant. Complementary feeding practices were collected by 24 hours diet recall method and and parental knowledge on IYC feeding was collected by KAP questionnaire.
