A biodegradable magnesium alloy promotes subperiosteal osteogenesis via interleukin-10-dependent macrophage immunomodulation.

In situ bone regeneration and vertical bone augmentation have been huge problems in clinical practice, always imposing a significant economic burden and causing patient suffering. Herein, MgZnYNd magnesium alloy rod implantation in mouse femur resulted in substantial subperiosteal new bone formation, with osteoimmunomodulation playing a pivotal role. Abundant macrophages were attracted to the subperiosteal new bone region and proved to be the most important regulation cells for bone regeneration.

[Research progress in diagnosis and treatment of salivary gland tumors].

Salivary gland tumor is one of the most common tumors in oral and maxillofacial regions. The diagnosis and treatment of salivary gland tumors had been a clinical characteristic project in Peking University School and Hospital of Stomatology since long time ago. Here we introduced the research progress in diagnosis and treatment of salivary gland tumors during the past 10 years.

A genome-wide survey of DNA methylation reveals hyper-methylation regulates after-ripening and dormancy of recalcitrant Panax notoginseng seeds.

DNA methylation plays a crucial role in regulating fruit ripening and seed development. It remains unknown about the dynamic characteristics of DNA methylation and its regulation mechanisms in morpho-physiological dormancy (MPD)-typed seeds with recalcitrant characteristics. The Panax notoginseng seeds are defined by the MPD and are characterized by a strong sensitivity to dehydration during the after-ripening process.

Relationship between morphological and genetic diversity of Phelipanche aegyptiaca in Xinjiang China.

Background: Phelipanche aegyptiaca is one of the most noxious parasitic weedy broomrapes in Xinjiang, China. Understanding its morphological polymorphism and genetic diversity can support effective control strategies. This study investigated the morphological and genetic diversity among and within populations from different geographical regions and host species across Xinjiang to characterize their relationships.

Massive gastrointestinal hemorrhage and iodine-125 seed migration due to hepatogastric fistula: a case report and literature review.

Background: Hepatogastric fistula (HGF) is an uncommon occurrence that can be associated with various medical conditions. The primary causes typically involve peptic ulcer disease, infections (such as pyogenic, amoebic or tuberculosis), or iatrogenic factors (like post transarterial chemoembolization or radiotherapy). Massive gastrointestinal hemorrhage following HGF is extremely rare, with iodine-125 (I) seed migration to the stomach through HGF not previously documented.
