Topical treatments in special populations of atopic dermatitis - Chinese perspective.

Introduction: Atopic Dermatitis (AD) is a common chronic, recurrent inflammatory skin disease, characterized mainly by polymorphic skin lesions and severe itching, significantly affecting patients' physical and mental health. The pathogenesis of AD is complex, involving multiple factors such as genetics, environment, immunity, and microbiota. In terms of treatment, traditional systemic therapies are gradually being replaced by more targeted molecular immunotherapies, and the range of topical medications has become more diverse.

Pseudoepitheliomatous hyperplasia misdiagnosed as cutaneous squamous cell carcinoma: a case report.

Pseudoepitheliomatous hyperplasia (PEH) is a rare histopathological reaction. Cases of PEH have been infrequently reported, and it's even rare to appear as a postsurgical complication. This case report describes the development of multiple masses and purulent discharge around an abdominal scar following surgery for hepatocellular carcinoma, which morphologically resembles squamous cell carcinoma (SCC), though pathology revealed no signs of malignancy.

Fibroblast Growth Factor 2 Attenuates Renal Ischemia-Reperfusion Injury via Inhibition of Endoplasmic Reticulum Stress.

Acute kidney injury (AKI) is a serious clinical disease that is mainly caused by renal ischemia-reperfusion (I/R) injury, sepsis, and nephrotoxic drugs. The pathologic mechanism of AKI is very complex and may involve oxidative stress, inflammatory response, autophagy, apoptosis, and endoplasmic reticulum (ER) stress. The basic fibroblast growth factor (FGF2) is a canonic member of the FGF family that plays a crucial role in various cellular processes, including organ development, wound healing, and tissue regeneration.

Antiangiogenic triterpenes isolated from Chinese herbal medicine Actinidia chinensis Planch.

Actinidia chinensis Planch. is a famous Chinese herbal medicine to treat many diseases such as cancers. Triterpenes, polyphenols and anthraquinones are normally considered as the main constituents for its effects.

Antiangiogenic polyketides from Peperomia dindygulensis Miq.

Two new polyketides: 2Z-(heptadec-12-enyl)-4-hydroxy-3,4,7,8-tetrahydro-2H-chromen-5(6H)-one (1) and 2-(heptadec-12-enyl)-5-hydroxy-5,6,7,8-tetrahydrochromen- 4-one (2), together with eleven known compounds: 4-hydroxy-2-[(3,4-methylenedioxy- phenyl)tridecanoyl] cyclohexane-1,3-dione (3), oleiferinone (4), 4-hydroxy-2-[(3,4- methylenedioxyphenyl)undecanoyl]cyclohexane-1,3-dione (5), 4-hydroxy-2-[(11-phenyl- undecanoyl)cyclohexane-1,3-dione (6), proctorione C (7), surinone C (8), 5-hydroxy- 7,8,4'-trimethoxyflavone (9), 5-hydroxy-7,8,3',4'-tetramethoxyflavone (10), 5-hydroxy- 7,3',4'-trimethoxyflavone (11), 5,8-dihydroxy-7,3',4'-trimethoxyflavone (12) and cepharanone B (13) were isolated from the whole plant of Peperomia dindygulensis Miq. Their structures were elucidated by spectroscopic methods, including 2D-NMR techniques. Compounds 2, 3, 5 and 8 inhibited human umbilical vein endothelial cell (HUVEC) proliferation and compounds 5 and 8 sharply suppressed HUVEC tube formation.

Secolignans with antiangiogenic activities from Peperomia dindygulensis.

Two new secolignans, peperomins G and H (1 and 2, resp.), were isolated from the whole plant of Peperomia dindygulensis, together with five known secolignans, peperomin A (3), peperomin E (4), peperomin B (5), 2,3-trans-2-methyl-3-{(3-hydroxy-4,5-dimethoxyphenyl)[5-methoxy-3,4-(methylenedioxy)phenyl]methyl}butyrolactone (6), 2,3-cis-2-(hydroxymethyl)-3-{bis[5-methoxy-3,4-(methylenedioxy)phenyl]methyl}butyrolactone (7). Their structures and configurations were elucidated by spectroscopic methods including 2D-NMR techniques.
