[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.

Effects of the Chinese Heart-Healthy Diet (Sichuan Cuisine Version) on the 10-year CVD risk and vascular age: a randomised controlled feeding trial.

Sichuan cuisine was previously fitted into the Chinese Heart-Healthy Diet (CHH) trial to verify the antihypertensive effect. Whether the modified Sichuan diet lessens cardiovascular disease (CVD) is not fully explored. We aimed to estimate the effects of the Sichuan version of CHH diet (CHH diet-SC) on the 10-year risk of CVD and vascular age.

[Evaluation of calcium intake levels and sources among pregnant women in a Chengdu hospital in 2017].

Objective: Investigate and evaluate the levels and sources of calcium intake of pregnant women in Chengdu during three trimesters.

Methods: Use the data of a cohort study in Chengdu in 2017. The healthy singleton pregnant women with 8-14 weeks of pregnancy in an obstetrical clinic of a maternal-and-child health care institution in Chengdu were selected as the object of the study.

Dietary fat quantity and quality in early pregnancy and risk of gestational diabetes mellitus in Chinese women: a prospective cohort study.

We aimed to examine the association between the quantity and quality of dietary fat in early pregnancy and gestational diabetes mellitus (GDM) risk. In total, 1477 singleton pregnant women were included from Sichuan Provincial Hospital for Women and Children, Southwest China. Dietary information was collected by a 3-d 24-h dietary recall.

Healthier diet associated with reduced risk of excessive gestational weight gain: A Chinese prospective cohort study.

Limited studies have examined the associations between diet quality and gestational weight gain (GWG) among Chinese pregnant women, adopting Chinese GWG guidelines. We prospectively investigate the associations of diet quality, using the Chinese Healthy Diet Index for Pregnancy (CHDI-P), which assessed diet quality from 'Diversity', 'Adequacy' and 'Limitation' dimensions with overall 100 points, with GWG among participants enroled in Southwest China. Food consumption was collected by 24 h dietary recalls for three consecutive days and CHDI-P scores were divided into tertiles.

[Intakes and sources of fat and fatty acids among pregnant women in Chengdu in 2017: a longitudinal study].

Objective: To analyze the intake of fat and fatty acids and their food sources of pregnant women in Chengdu.

Methods: Participants were from a cohort study in 2017, which was conducted among 1652 healthy singleton pregnant women within 6-14 weeks of gestation in a maternity out-patient clinic of maternal-and-child health care institution in Chengdu, Sichuan Province. Data on maternal demographic characteristics was collected by questionnaire.

Detection and Genetic Characterization of Atypical Porcine Pestivirus in Piglets With Congenital Tremors in Southern China.

Atypical porcine pestivirus (APPV) is an RNA virus newly discovered from swine in Asia, Europe, and the Americas. This novel virus has been confirmed as the cause of congenital tremor (CT) in piglets, which causes extensive economic losses to the swine industry. To investigate the genetic diversity and evolutionary relationship of APPV in China, 83 piglet samples with severe CT clinical signs were obtained from 12 commercial swine farms in 3 provinces of Southern China.

Complete Genome Sequence of Senecavirus A Strain SVV HN16 Identified in China.

A virus that caused blisters and ulcers in pigs in China was detected to be a strain of Senecavirus A (SVA). Complete genome sequencing and analysis results showed that the isolate shares 93.8% to 99.

Evolution of porcine reproductive and respiratory syndrome virus GP5 and GP3 genes under swIFN-β immune pressure and interferon regulatory factor-3 activation suppressed by GP5.

In this study, a highly pathogenic porcine reproductive and respiratory syndrome virus (HP-PRRSV) strain, PRRSV GD07 was continuously propagated in MARC-145 cell cultures primed with swIFN-β for 50 passages to develop the PRRSV GDβfn strains. And a control strain PRRSV GDfn was passaged without swIFN-β. The sequencing analysis indicated that under swIFN-β immune pressure, molecular variation of PRRSV GP5 was accelerated in gene (NS/S>2.

Complete Genome Sequence of a Very Virulent Porcine Epidemic Diarrhea Virus Strain, CH/GDGZ/2012, Isolated in Southern China.

The classical symptoms of porcine epidemic diarrhea (PED) are acute diarrhea and dehydration. The isolated porcine epidemic diarrhea virus (PEDV) CH/GDGZ/2012 strain was obtained from the feces of diseased pigs in 2012 in southern China. We report the complete genome sequence of strain CH/GDGZ/2012, which might be useful for better understanding the molecular characteristics of this virus.

swIFN-β promotes genetic mutation of porcine reproductive and respiratory syndrome virus in Marc-145.

This result, for the first time, demonstrates that under swine interferon-β (swIFN-β) immune pressure molecular variation of porcine reproductive and respiratory syndrome virus (PRRSV) accelerates. PRRSV-A1 strain was continuously propagated in Marc-145 cells primed with swIFN-β for 20 passages to develop RRRSV-A1βf20 strains while PRRSV-A1f20 was control without swIFN-β respectively. NSP2, ORF3, ORF5 and ORF6 genes of these strains were amplified, cloned and sequenced.

Genomic comparison of foot-and-mouth disease virus R strain and its chick-passaged attenuated strain.

The present study examined the genomic differences between foot-and-mouth disease virus (FMDV) R strain and its attenuated, chick-passaged (R(304)) strain. Eleven pairs of primers were used to amplify the complete genome of FMDV R and R(304) by RT-PCR. Each fragment was cloned into pMD18-T vector and sequenced.
