Background: Photoaging is a degenerative biological process that affects the quality of life. It is caused by environmental factors including ultraviolet radiation (UVR), deep skin burns, smoking, active oxygen, chemical substances, and trauma. Among them, UVR plays a vital role in the aging process.

Lake Poyang has significant differences in hydrological characteristics between the flood and dry seasons. Unraveling the optical composition, bioavailability, fate, and balance of chromophoric dissolved organic matter (CDOM) and organic carbon fluxes in Lake Poyang under different hydrological conditions can help provide advanced schemes on carbon cycling, the transfer and transformation of organic matter, and water resource management of the lake. Three fluorescent components, including a humic-like (C1), a tryptophan-like (C2), and a tyrosine-like (C3) component, were obtained using three-dimensional fluorescence spectroscopy coupled with parallel factor analysis.

Lake Qinghai is the largest lake in China and is of great significance to maintain the ecological security of the Qinghai-Tibet Plateau. Few studies have been carried out to investigate the optical composition and source of chromophoric dissolved organic matter (CDOM) in large lakes on the Qinghai-Tibet Plateau. It is of great significance to study the source and optical dynamics of CDOM in Lake Qinghai watershed for water quality protection and filling in the gaps in the knowledge of CDOM variability in a remote area.

In the past few decades, China's rapid industrial activities and urbanization processes have greatly impacted the urban surface water ecosystem. The changes in the quality of urban surface water directly affect the supply and carbon cycling of urban waters. We collected 50 water samples from urban rivers, lakes, and reservoirs in the city of Changchun in June 2020.

Poyang Lake and Dongting Lake are the two largest freshwater lakes in China connected to the Yangtze River. Changes in the water quality of the two lakes are critical to the water security of the residents surrounding the lakes. Analyses of the optical properties, including chromophoric dissolved organic matter (CDOM) absorption and fluorescence spectroscopy coupled by parallel factor analysis (PARAFAC), were carried out to investigate the dynamics of CDOM in the two lakes in different hydrological scenarios.

The bio-lability of chromophoric dissolved organic matter (CDOM) directly reflects its biodegradability potential, and also affects the migration and conversion of pollutants and impacts water quality. This study combines excitation-emission matrices and parallel factor analysis (EEMs-PARAFAC) with laboratory 28 days of bio-incubation experiments, and analyzed the bioavailability characteristics of CDOM samples collected from Lake Gaoyou, Lake Nansi and Lake Dongping in flood season and dry season. Our results showed that:① four fluorescent components were obtained using EEMs-PARAFAC, including a microbial humic-like C1, a terrestrial humic-like C4, a tryptophan-like C2, and a tyrosine-like C3.

Severe acne presents sexual dimorphism in its incidence in Chinese population. It is more prevalent in males. To assess the possible Y chromosomal contribution to severe acne risk in Han Chinese males, we analyzed 2041 Y chromosomal SNPs (Y-SNPs) in 725 severe acne cases and 651 controls retrieved from our recent genome-wide association study data.

Objective: To investigate the effects of aerosolized signal transducer and activator of transcription 1 (STAT1) antisense oligonucleotides (ASON) on the expressions of TGF-beta(1), PAI-1, collagen Type I and III and hydroxyproline in lung tissue of pulmonary fibrosis induced by bleomycin (BLM) in rats.

Methods: Forty-five adult female Wistar rats were randomly divided into 3 groups: normal saline (NS) group, BLM group and ASON group. The BLM group and the ASON group were intratracheally instilled with BLM while the NS group was instilled with NS.

Objective: To investigate the actual condition of the sexual physiological and psychological development of the high school students in Yibin in order to get a reliable basis for sexual education of the teenagers.

Methods: With a proportion of 1% to the whole, 2,770 students were randomly selected from eight high schools in the urban and rural areas of the city. We devised a questionnaire and asked each student to fill in his or her answers presently.
