Article Synopsis
- - The new mechanochromic light control technology aims to create energy-saving windows that adjust to solar irradiation but faces challenges in selective modulation for various scenarios.
- - A layer-by-layer assembly method is introduced to produce a film that responds mechanically, allowing for dynamic modulation of visible and near-infrared light, with optical modulation rates of up to 42.4% at 550 nm.
- - The multilayer structure enhances both the film's optical performance and its durability, surviving up to 100,000 stretching cycles, and demonstrates a cooling effect in real-world applications, potentially benefiting energy-efficient design.

Moreover, evidence is limited in non-European populations. We investigated associations of CRP and fibrinogen with risks of incident major coronary events (MCE), ischemic stroke (IS) and intracerebral hemorrhage (ICH) in a cohort of Chinese adults.

Objectives: This study aimed to examine the associations of a combination of modifiable, healthy lifestyle factors with the risks of ischemic cardiovascular diseases and estimate the proportion of diseases that could potentially be prevented by adherence to these healthy lifestyle patterns.
Methods: This study examined the associations of 6 lifestyle factors with ischemic heart disease and ischemic stroke (IS) in the China Kadoorie Biobank of 461,211 participants 30 to 79 years of age who did not have cardiovascular diseases, cancer, or diabetes at baseline.
Article Synopsis
- The study aimed to assess the links between sleep duration, snoring, and diabetes among different gender and menopausal status groups in rural China.
- Researchers analyzed data from over 57,000 participants aged 30-79 using logistic regression to determine the odds of diabetes based on sleep patterns and snoring.
- Results indicated a U-shaped relationship between sleep duration and diabetes risk in postmenopausal women, while snoring was associated with diabetes across all groups, impacted by factors like socioeconomic status and health behaviors.*

Objective: To explore the association between sleep duration and stroke in adults.
Methods: Baseline data of 57 704 subjects who were aged 30-79 years and enrolled into China Kadoorie Biobank (CKB) study from Tongxiang county, Zhejiang province were analyzed. Multiple logistic regression analysis was conducted to investigate the putative association between sleep duration and stroke after adjusting for potential confounders.
Background: Greater adiposity is associated with higher blood pressure. Substantial uncertainty remains, however, about which measures of adiposity most strongly predict blood pressure and whether these associations differ materially between populations.
Methods: We examined cross-sectional data on 500 000 adults recruited from 10 diverse localities across China during 2004-08.
Background: Despite the great burden of chronic respiratory diseases in China, few large multicentre, spirometry-based studies have examined its prevalence, rate of underdiagnosis regionally or the relevance of socioeconomic and lifestyle factors.
Methods: We analysed data from 512 891 adults in the China Kadoorie Biobank, recruited from 10 diverse regions of China during 2004-2008. Air flow obstruction (AFO) was defined by the lower limit of normal criteria based on spirometry-measured lung function.
Background: In many Western populations, blood pressure varies moderately with season and outdoor temperature. Relatively little is known about effects of seasonal changes in blood pressure on the detection and control of hypertension in general populations, especially in low- and middle-income countries.
Methods: We analysed cross-sectional data of 57 375 (42% men) participants aged 30-79 (mean 52.
Background: A mutation in MEF2A (myocyte enhancer factor-2A) had been reported to be the first gene linked directly to coronary artery disease (CAD). However, an opposing opinion was proposed recently that MEF2A mutations are not a common cause of sporadic CAD. In this study, we screened exon 11 of the MEF2A gene in people of the Han nationality in China and finished some functional analysis of found variations.

Methods: The clinicopathologic features of 40 autopsy cases of diabetes mellitus were studied. The hearts from another 40 cases of non-diabetic elderly deceased were used for comparison.
Objective: To evaluate the feasibility, safety and diagnostic accuracy of pharmacologic stress of (99m)Technetium-MIBI single-photon emission computed tomography (SPECT) with intravenous adenosine triphosphate (ATP) in patients with suspected coronary artery disease.
Methods: The study group included 263 patients who were suspected of having coronary artery disease. All patients underwent (99m)Tc-MIBI myocardial perfusion imaging with ATP infusion (0.
