Indoor environment and health have drawn public attention worldwide. However, the joint health effects and mechanisms of exposure to different types of indoor environmental factors remain unclear. We established an exploratory panel study on indoor environment and health effects among young adults in China (the China IEHE Study) to comprehensively investigate 3M issues, including multiple indoor environmental factors, multiple health effects, and multiple omics methods for mechanism exploration. This protocol aims to systematically introduce the entire China IEHE Study. Eighty-one young adults aged 18-28 years from a university adjacent to traffic arteries in Beijing were recruited and followed up four times. Sham/real air purification intervention was simultaneously applied in a randomized crossover order. A broad range of indoor physical, chemical, and biological factors were characterized through real-time monitoring and external and internal exposure analyses. Subclinical health indices reflecting cardiopulmonary, sleep, and cognitive health were repeatedly measured in a prospective order. Various biosamples including fasting venous blood, morning urine, nasal mucosal lining fluid, and exhaled breath condensate were collected to explore the underlying biological mechanisms. The China IEHE Study comes up with an enlightening framework for future prospective studies associated with the exploration of multisystem health effects and underlying biological mechanisms of indoor exposure.

Background: Currently, paradoxical findings exist regarding the level of functioning in individuals with Hikikomori (prolonged social withdrawal).
Aims: This systematic review aimed to clarify the functioning, disability, and health of individuals with Hikikomori and their families in comparison to those without Hikikomori.
Method: Relevant studies were searched from April 22 to 25, 2022, using MEDLINE, PsycINFO, Scopus, and two Japanese databases.
Aim: The aim of this study is to investigate the effect of obesity on the treatment outcomes of lumbar transforaminal epidural steroid injections (TFESIs).
Material And Methods: This retrospective study included patients who underwent single-level TFESI in a pain management center between January 2021 and April 2023. Body mass index (BMI) of the patients was evaluated based on the World Health Organization guidelines.
Combining Hard Shell with Soft Core to Enhance Enzyme Activity and Resist External Disturbances.

Immobilizing enzymes onto solid supports having enhanced catalytic activity and resistance to harsh external conditions is considered as a promising and critical method of broadening enzymatic applications in biosensing, biocatalysis, and biomedical devices; however, it is considerably hampered by limited strategies. Here, a core-shell strategy involving a soft-core hexahistidine metal assembly (HmA) is innovatively developed and characterized with encapsulated enzymes (catalase (CAT), horseradish peroxidase, glucose oxidase (GOx), and cascade enzymes (CAT+GOx)) and hard porous shells (zeolitic imidazolate framework (ZIF), ZIF-8, ZIF-67, ZIF-90, calcium carbonate, and hydroxyapatite). The enzyme-friendly environment provided by the embedded HmA proves beneficial for enhanced catalytic activity, which is particularly effective in preserving fragile enzymes that will have been deactivated without the HmA core during the mineralization of porous shells.

Albuvirtide (ABT) is a novel long-acting fusion inhibitor for human immunodeficiency virus type 1 (HIV-1), and may be co-administered with rifampicin (RIF) in patients concurrent with tubercle bacillus and HIV-1. This study was conducted to investigate the pharmacokinetic effect of co-administration of the two drugs. In the study, 24 healthy volunteers were randomized to receive ABT alone or with RIF.

Background: Tracheal, bronchial, and lung cancers (TBL cancers) pose a significant global health challenge, with rising incidence and mortality rates, particularly in China. Studies from the Global Burden of Disease (GBD), 2021, can guide screening and prevention strategies for TBL cancer. This study aims to provide a comprehensive analysis of the burden of TBL cancers in China compared to global data.
