Risk factors for electrocardiographic left ventricular hypertrophy in a young Chinese general population: the Hanzhong adolescent cohort study.

Background: Electrocardiographic left ventricular hypertrophy (ECG-LVH) is a common manifestation of preclinical cardiovascular disease. The present study aimed to investigate risk factors for ECG-LVH and its prevalence in a cohort of young Chinese individuals.

Methods: (1) A total of 1515 participants aged 36-45 years old from our previously established cohort who were followed up in 2017 were included.

Risk factors for subclinical renal damage and its progression: Hanzhong Adolescent Hypertension Study.

Background/objectives: Chronic kidney disease (CKD) is a global public health problem, including in China. The aim of this study was to identify the risk factors for the development and progression of subclinical renal disease (SRD) in a Chinese population. We also examined whether the impact of the risk factors on SRD changed over time.

Association of uric acid in serum and urine with subclinical renal damage: Hanzhong Adolescent Hypertension Study.

Background And Objectives: The aim of the study was to examine the associations of uric acid (UA) in blood and urine with subclinical renal damage (SRD) and its progression in a Chinese cohort.

Methods: 1) 2342 participants from our previously established cohort who were followed up in 2017 were included. Cross-sectional analysis was used to examine the relationships between serum and urinary UA and the risk of SRD.

[Law of Pollutant Erosion and Deposition in Urban Sewage Network].

In order to investigate the scouring and deposition law of pollutants in urban sewer systems, the investigation of sewer systems was carried out in Xi'an. The results showed that the thickness of sediment in the branch pipe and the main pipe varied obviously. At the peak of the drainage, the velocity increased gradually, and the thickness of the pipeline sediment decreased.

[Sediment Characteristics of Sewer in Different Functional Areas of Kunming].

The problem of sediment deposition in urban sewer network in different levels, will not only reduce the sewer flow ability, but also release pollutants and generate secondary pollution. The impact of secondary pollution is more serious in the study area, Kunming, because of the combined sewer overflow in rainy season. In order to obtain the characteristics of the sewer sediments in Kunming, the sewer sediments from residential area, service area, cultural district, and business district were investigated and collected.
