Purpose: Intestinal fibrous stenosis due to Crohn's disease (CD) is highly prevalent. Although several clinical risk factors for fibrous stenosis have been identified, such as perianal fistulizing disease, small bowel disease location, and deep mucosal ulceration, predicting fibrous stenosis remains challenging. The intestinal microbiota plays a crucial role in the development and progression of CD.

MicroRNAs (miRNAs) play a pivotal role in radiotherapy immunity. In this study, we aimed to investigate the mechanism by which miR-196a-5p affects radioresistance in lung cancer.

Methods: On the basis of literature review and focus group interview, the initial item pool of CASI management model for cancer patients was determined. The Delphi method was used to conduct two rounds of letter consultation with 36 authoritative and representative experts to determine the content and weight of indicators of CASI multidisciplinary management model for cancer patients.
Objective: To evaluate the effects of a video-assisted education intervention on informed consent and patient education for peripherally inserted central catheters (PICCs).
Methods: We conducted a randomized controlled trial comparing the effects on informed consent of video-assisted patient education and traditional face-to-face discussion in a catheter outpatient ward of a cancer centre in Guangzhou, China, in 2018. Participants were 140 patients randomly allocated (1:1 ratio) to two groups: video-assisted or traditional intervention.
Passive sampling techniques have been widely used to determine the dissolved concentration profiles of hydrophobic organic compounds (HOCs) in sediment porewater. However, the effects of having a protection for the passive sampler on profiling HOCs concentrations in sediment porewater, especially in deep sediment, have remained unclear. To address this issue, low density polyethylene passive samplers with and without protectors, which consisted of glass fiber filter and porous stainless steel shield, were simultaneously deployed in sediment of the Dongjiang River, South China.

To address this research gap, the present study conducted an assessment of human health risk for four age groups through inhalation exposure to size fractionated particle-bound and gaseous halogenated flame retardants (polybrominated diphenyl ethers (PBDEs) and alternative halogenated flame retardants (AHFRs)) and organophosphate esters (OPEs) at indoor and outdoor environments (school, office, and residence) in three districts of a megacity (Guangzhou, China). Results demonstrated that OPEs were the dominant components among all targets.

Objective: To investigate the gene mutation types and spectrum of α, β-thalassemia in Fuzhou area of China.
Methods: Thalassemia gene screening was performed in the women receiving physical, prenatal, and pre-pregnancy examination, and the patients with suspected thalassemia in our hospital from July 2013 to March 2018.Genotypes of thalassem were detected by Gap-PCR and RDB-PCR.
Background: The insect olfactory system is a highly specific and sensitive chemical detector, which plays important roles in feeding, mating and finding an appropriate oviposition site. The ecological niche of Bombyx mori has changed greatly since domestication from B. mandarina, and its olfactory response to environmental odorants clearly decreased.

In the present study, size-dependent particle and gaseous samples were collected both indoors and outdoors within selected schools, offices and residences located in three districts of Guangzhou, China with different urbanization levels during the dry and wet weather seasons. Results from measurements of PAHs showed that higher total PAH concentrations occurred in residential areas than in other settings and in indoor than in outdoor environments.

This is particularly important in China, where insufficient data of national scale have been acquired on the occurrence of any organic pollutants in the country's water bodies. To fill the knowledge gap, we employed passive samplers to survey polycyclic aromatic hydrocarbons (PAHs) in 42 freshwaters throughout the country.
