Development of grip strength and its relationship with body composition in preschoolers / 中国学校卫生

Objective@#To study the development of grip strength and its relationship with body weight, height and body composition in preschool children.@*Methods@#Data was collected from 900 children aged 3-6 years in 4 preschools in Beijing during Sept. to Oct. of 2020. A questionnaire survey (birth weight, dietary and exercise), height, weight, bioelectrical impedance analysis of body composition and dominant hand grip strength tests were conducted. Partial correlational analysis, multivariate linear regression were used for association between grip strength and body composition.@*Results@#The grip strength gradually increased with age, from (5.2±1.7) to (9.3±2.5)kg in boys ( F=57.93, P <0.01), and from (4.3±1.6) to (7.9±2.5)kg in girls ( F=48.77, P <0.01). Grip strength in boys were significant higher than that of girls ( t=6.42, P <0.01). The grip strength increased with weight status in boys ( F=5.35, P <0.01), with highest in obese group, followed by overweight and normal weight group. After adjusted for height, weight and birth weight, as well as maternal education, food consumption during the past week, grip strength in boys was positively correlated with fat free mass, upper limb muscle mass ( r=0.11, 0.09, P <0.05), and negatively correlated with body fat mass ( r=-0.18, P <0.05). Grip strength in girls was negatively correlated with body fat mass, and positively correlated with fat free mass ( r= -0.09, 0.09, P <0.05). Grip strength varied significantly by age, fat free mass and upper muscle mass in boys ( F=66.75, P < 0.01), and by age and fat free mass in girls ( F=150.81, P <0.01).@*Conclusion@#The grip strength can partially reflect changes in fat free mass for boys and girls, it also reflect changes in upper limb muscle mass for boys. Increases in fat free mass helps grip strength improvement.

N-acetylcysteine reduces artesunate-induced pancreatic carcinoma cell death by activating protective autophagy via the AMPK/mTOR pathway / 西安交通大学学报(医学版)

【Objective】 In this study， reactive oxygen species （ROS） scavenger N-acetyl-L-cysteine （NAC） was used to explore the inhibitory effect and mechanism of artesunate （ART） on pancreatic carcinoma （PC） cells. 【Methods】 Different concentrations of ART interfered with 3 PC cell lines CFPAC-1， Capan-2 and BxPC3. Cell viability was measured by CCK8； cell migration ability was measured by Transwell method， and the expressions of migration-related proteins E-cadherin， N-cadherin and Vimentin were measured by Western blotting. ROS probe DCFH-DA was used to measure intracellular ROS； LC3 cell immunofluorescence （IF） was used to detect the formation of intracellular autophagosomes. After adding NAC or autophagy inhibitor 3-MA， the cell viability was tested again by CCK8， and the expressions of p-AMPK/ AMPK， p-mTOR/mTOR， p62 and LC3Ⅱ/Ⅰ were detected by Western blotting. 【Results】 ART inhibited the growth of CFPAC-1 and Capan-2 in a time- and dose-dependent manner. After treatment of CFPAC-1 and Capan-2 cells with 200 μmol/L of ART for 48 h， the expression of E-cadherin was upregulated， while N-cadherin and Vimentin were downregulated， and the cell migration ability was significantly reduced. ART significantly upregulated intracellular ROS level and promoted the formation of autophagosomes. NAC could reduce the inhibitory effect of ART on CFPAC-1 and Capan-2 cells， upregulate p-AMPK/AMPK， P62 and LC3Ⅱ/Ⅰ， downregulate the expression of p-mTOR/mTOR， and intensify autophagy. 3-MA could not reverse the inhibitory effect of ART on PC cells. 【Conclusion】 ART is dependent on ROS， but not on autophagy， in exerting an anti-pancreatic carcinoma effect. NAC attenuates the inhibitory effect of ART on PC cells by activating protective autophagy through AMPK/mTOR signaling pathway.

Terminology interpretation of nutritional risk screening (NRS 2002-01.017)and malnutrition diagnosis (GLIM-phenotypic criteria 01.028, etiologic criteria 01.029) / 中华临床营养杂志

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.

The development of malnutrition assessment criteria and the analysis of current problems / 中华外科杂志

It is well known that parenteral and enteral nutrition support is helpful to improve clinical outcomes in patients with malnutrition or nutritional risk, and surgical nutrition has been used in China for 40 years. However, there is still insufficient awareness of malnutrition among clinical workers. There were different opinions from many experts after the publications of the European Society for Parenteral and Enteral Nutrition (ESPEN) consensus of malnutrition assessment 2015 and ESPEN guidelines on definitions and terminology of clinical nutrition 2017. Global Leadership Initiative on Malnutrition (GLIM) criteria for the diagnosis of malnutrition has also been published in 2018. Though it is lack of clinical validation, it is a big step forward. In order to achieve better prevention and treatment of malnutrition in clinical work, this present paper analyzes and compares the core contents of malnutrition assessment (diagnosis) in recent years, proposes current practical strategy for Chinese clinical workers, emphasizes that GLIM criteria cannot replace the three steps named "screening-assessment-intervention" .
