The aim of this study was to observe the clinical efficacy and safety of propranolol in the treatment of hemangioma, and to reveal its possible mechanism. A total of 129 cases of proliferative hemangioma were divided into two groups: i) Treatment (n=97), in which the patients received oral propranolol therapy and ii) observation (n=32), in which the patients underwent clinical observation. The changes in the hemangiomas were noted and compared between the two groups. In addition, the heart rate, blood glucose levels, liver, kidney and thyroid function of the patients in the treatment group were monitored prior to and following treatment; the ELISA method was used for the measurement of the patients' serum concentrations of vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF) and matrix metalloproteinase-9 (MMP-9) at the same time-points. A significant difference in curative effect was found between the treatment and observation group. The concentration of free thyroxine and sensitive thyroid-stimulating hormone and the heart rate of the treatment group exhibited significant changes prior to and following medication, but no statistical significance was found in the changes in blood glucose, liver and kidney function and free triiodothyronine concentration. Furthermore, the serum concentrations of VEGF, bFGF and MMP-9 in the treatment group 8 weeks after medication were decreased significantly compared with those before treatment. In conclusion, oral propranolol has a good curative effect in the treatment of proliferative hemangioma, with few side effects and a high level of safety. The mechanism underlying the effects of propranolol may be associated with the downregulation of VEGF, bFGF and MMP-9 expression.

Background: Vascular contributions to cognitive impairment and dementia (VCID) and Alzheimer's disease (AD) are the two most common forms of dementia, with overlapping risk factors including cardiovascular risk factors such as hypertension and dyslipidemia. The etiology of both VCID and AD shows sex-based differences, as well as sex-based differences in cardiovascular risk factors. However, how sex differences influence AD and angiogenic biomarkers in older adults who have high cardiovascular risk factors is not known.

Background: While Alzheimer disease (AD) is the most common cause of dementia, it has long been recognized that cardiovascular and cerebrovascular health plays a major role in cognitive function. As such, the development of accessible biomarkers to assess vascular cognitive impairment and dementia (VCID) is a key step towards identifying effective prevention and treatment strategies. While a set of blood-based VCID biomarkers has been under investigation, there is a critical paucity of data from genetically admixed individuals.

Objective To investigate the effect of serum containing Xinfeng capsule (XFC) on the angiogenesis of human umbilical vein endothelial cells (HUVEC) induced by rheumatoid arthritis fibroblast-like synoviocytes (RA-FLS) and its mechanism of action. Methods An in vitro co-culture model of RA-FLS and HUVEC was established. Serum containing XFC was prepared by oral gavage of SD rats.

Introduction: The purpose of this study was to compare the growth factor concentrations in undiluted autologous platelet-rich plasma (APRP) and autologous serum (AS) eye drops.
Methods: This was a single-center, prospective trial conducted in a tertiary university hospital in Bangkok, Thailand. Ninety-six patients with moderate-to-severe dry eye disease, who were randomly assigned to receive either 100% APRP or 100% AS, were enrolled in the study.
