[Status and perspective of soil fauna eco-geography in China].

As regulators of the surface land processes, soil fauna communities are the vital foundations for healthy terrestrial ecosystems. Soil fauna have been studied in China for more than 70 years. Great progresses have been achieved in exploring soil fauna species composition and geographical distribution patterns.

A xonotlite nanofiber bioactive 3D-printed hydrogel scaffold based on osteo-/angiogenesis and osteoimmune microenvironment remodeling accelerates vascularized bone regeneration.

Background: Coordination between osteo-/angiogenesis and the osteoimmune microenvironment is essential for effective bone repair with biomaterials. As a highly personalized and precise biomaterial suitable for repairing complex bone defects in clinical practice, it is essential to endow 3D-printed scaffold the above key capabilities.

Results: Herein, by introducing xonotlite nanofiber (Ca(SiO) (OH), CS) into the 3D-printed silk fibroin/gelatin basal scaffold, a novel bone repair system named SGC was fabricated.

TNFSF15 facilitates differentiation and polarization of macrophages toward M1 phenotype to inhibit tumor growth.

Macrophages of the M2 phenotype in malignant tumors significantly aid tumor progression and metastasis, as opposed to the M1 phenotype that exhibits anti-cancer characteristics. Raising the ratio of M1/M2 is thus a promising strategy to ameliorate the tumor immunomicroenvironment toward cancer inhibition. We report here that tumor necrosis factor superfamily-15 (TNFSF15), a cytokine with anti-angiogenic activities, is able to facilitate the differentiation and polarization of macrophages toward M1 phenotype.

Menetrier's disease and differential diagnosis: A case report.

Background: Gastric mucosal hypertrophy, also known as Menetrier's disease (MD), is more common in men over 50 years of age, and the cause is unknown. The symptoms of the disease are atypical, mostly accompanied by hypoproteinemia and edema, and sometimes accompanied by symptoms such as epigastric pain, weight loss, and diarrhea. Most experts believe that the site of the disease is mainly located in the fundus of the stomach and the body of the stomach.
