[Cross-Sectional Study of Nutritional Service Capacity for Infants and Toddlers in Urban and Rural Medical Facilities in Sichuan Province].

Objective: To investigate and analyze the current status and challenges of infant and toddler nutritional services in urban and rural medical facilities in Sichuan Province.

Methods: In 2022, a questionnaire survey was conducted to collect data on infant and toddler nutritional services, including feeding guidance, physical growth assessment, and micronutrient deficiency screening, as well as information on personnel and tools in medical facilities throughout Sichuan Province. The provision of nutritional services was analyzed and the urban-rural disparities were assessed.

Effects of the Chinese heart-healthy diet (Sichuan cuisine) on lowering blood pressure in adults with hypertension: a randomized controlled feeding trial.

Background And Objectives: Sichuan cuisine is characterized by high salt and oil content. We aimed to evaluate the effects of the Sichuan cuisine version of Chinese heart-healthy diet (CHH diet-SC) on blood pressure reduction among hypertensive adults.

Methods And Study Design: The Chinese heart-healthy diet (CHH) trial was a multicenter randomized controlled feeding trial among Chinese hypertensive people.

Does an antihypertensive diet cost more? Analysis from the Chinese Heart-Healthy diet trial.

Objective: To determine whether the Chinese heart-healthy diet (Sichuan cuisine version) (CHH diet-SC) was more expensive than the conventional Sichuan diet and explore the food groups and nutrients that mainly affected the cost of CHH diet-SC.

Design: Cost analysis of 4-week intervention diets in the Sichuan center representing southwestern China in the CHH diet study.

Setting: A multicentre, parallel-group, single-blind, randomised feeding trial evaluating the efficacy of lowering blood pressure with the cuisine-based CHH diet.

Hexamethyldisilazane-triggered room temperature synthesis of hydrophobic perovskite nanocrystals with enhanced stability for light-emitting diodes.

A novel facile room-temperature, hexamethyldisilazane (HMDS)-mediated strategy is demonstrated for the synthesis of all-inorganic perovskite colloidal nanocrystals (NCs). As a unique reaction-triggering and morphology-directing agent, HMDS is introduced for the first time to trigger the room-temperature reaction for generating perovskite NCs with controlled morphology and optical properties. Particularly, the stability of the resulting NCs is greatly enhanced due to the surface modification by hydrophobic -CH groups from HMDS.

Trivalent ion mediated abnormal growth of all-inorganic perovskite nanocrystals and their divergent emission properties.

In this work, a new trivalent ion-mediated one-pot synthetic protocol is reported to create two well-defined optical absorbance and photoluminescence (PL) emissions in all-inorganic halide perovskite nanocrystals (NCs). The foreign M3+ cations (M = Bi, Al, In), typically from BiBr3, BiFeO3, BiCl3, AlBr3 or InBr3, function as capping ligands for generating a growth-constrained thinner nanoplatelet (NPL) population displaying the quantum confinement effect. The formation mechanism of the growth-constrained NPLs is proposed based on density functional theory (DFT) on the different slab energy of the representative NPLs achieved in the presence of Bi3+ ions and the density of states (DOS) of the supposed bulk perovskites.
