This study systematically assessed GI cancer risks during working-age period (15–64 years) across 204 countries from 1990 to 2021. Key findings: (1) In 2021, approximately 1 in 46 individuals developed and 1 in 73 died from GI cancers during working age globally; (2) Colorectal cancer showed the highest incidence risk (0.91%), while gastric cancer had the highest mortality risk (0.35%); (3) Males faced approximately twofold higher risks than females, with East Asia and Mongolia exhibiting the highest regional and national risks, and ages 40–64 representing the high-risk period; (4) Despite overall declining trends, colorectal cancer incidence risk continued to rise. These findings provide evidence-based insights for developing targeted screening strategies.

A new review in Chinese Medical Journal details progress in nanocarrier-based cancer therapy. It analyzes polymeric, lipidic, and other nanoplatforms, their roles in immunotherapy, chemotherapy, radiotherapy, and addresses translation challenges like scalability and biosafety.

A new study published in iMetaMed reveals that potassium sorbate, a common food preservative, may cause acute kidney injury by disrupting intercellular communication. Using an integrated approach combining network toxicology, machine learning, and single-cell RNA sequencing, researchers identified the amyloid precursor protein as a central mediator of kidney damage, interacting with immune cells via specific signaling axes.

A new Chinese expert consensus provides critical guidance for using medical imaging to determine whether pancreatic ductal adenocarcinoma (PDAC) can be surgically removed. The consensus, developed by the Group of Abdomen of the Chinese Society of Radiology, emphasizes a multidisciplinary team (MDT) approach and outlines specific imaging techniques for accurate staging. Key recommendations establish contrast-enhanced CT as the primary tool for assessing local tumor spread, while MRI is prioritized for detecting elusive liver metastases. The guidelines also address the limitations of current imaging in evaluating treatment response and highlight the role of diagnostic laparoscopy. This standardized framework aims to improve preoperative planning, personalize treatment strategies, and ultimately enhance patient outcomes across China.

Deciphering true active sites under identical mass transport conditions is crucial for understanding catalytic mechanisms. By establishing uniform mass transfer and implementing controlled experiments to eliminate interfering factors, the research team identified Cu(100) grain boundaries as the key sites driving efficient C₂₊ production. Advanced characterization and theoretical calculations confirmed these sites facilitate asymmetric C–C coupling between *CHO and *CO intermediates, providing critical insights for rational catalyst design.

Co atoms are uniformly incorporated in NiS nanoparticles to fabricate homogeneous NiCoS cocatalyst on TiO₂ surface by a facile photosynthesis strategy. The optimized NiCoS/TiO₂(1:2) photocatalyst display the highest H₂ production performance, outperforming the NiS/TiO₂ and CoS/TiO₂ samples. The incorporated Co atoms break the electron distribution symmetry in NiS, thus essentially increasing electron density of S atoms to weaken S-H_ad bonds for efficient H_ad adsorption and desorption, endowing the NiCoS cocatalysts with a highly active H₂ evolution process. The integrated homogeneous NiCoS nanoparticles with TiO₂ could rapidly transfer photogenerated electrons and efficiently facilitate the interfacial H₂ evolution process, thus achieving enhanced photocatalytic H₂ generation activity.
