BACKGROUND The purpose of this study was to (1) identify specific miRNAs in growth hormones (GH)-secreting pituitary adenomas; (2) determine the relationship between the expression of these miRNAs and tumor size, somatostatin analogs treatment, and responsiveness to somatostatin analogs (SSA). METHODS Fifteen GH-secreting adenomas patients were treated(More)
OBJECTIVE To investigate whether 4-month preoperative lanreotide treatment would improve the surgical cure rate of newly diagnosed acromegalic patients with macroadenomas. DESIGN A prospective, randomised study. METHODS After a baseline evaluation, patients were randomly assigned to 4-month preoperative treatment with lanreotide (starting with 30 mg/2(More)
Dermal defection and the degree of its loss determine the natural process of wound healing, which is the key reason leading to excess scar hyperplasia. The function of tri-dimensional structure in dermis acts as a template to regulate the properties of reparative cells. The template structure induces the reparative cells to grow into the structure which(More)
OBJECTIVES To determine the incidence, risk factors, diagnostic procedures, and management of cerebrospinal fluid (CSF) leaks following trans-sphenoidal pituitary macroadenoma surgery. METHODS Retrospective analysis of 592 patients. RESULTS Intra- and post-operative CSF leaks occurred in 14.2 and 4.4% of patients, respectively. Surgical revision, tumor(More)
To determine the effect of artesunate (ART) on the rat pituitary adenoma GH3 cell line to evaluate its potential as a novel agent in growth hormone (GH) adenoma and to investigate its underlying mechanisms of action. The MTT assay was used to assess cell proliferation. DAPI staining was used to visualise apoptotic changes in the nucleus. We also analyzed(More)
Although the etiology underlying scar formation is not well understood, previous studies revealed that endothelial cells play a role in the pathogenesis of scar development. Recently, the authors developed a reliable technique to obtain endothelial cells from hypertrophic scars that involved separation of cells from the scar tissue matrix and isolation from(More)
Excessive growth hormone (GH) is usually secreted by GH-secreting pituitary adenomas and causes gigantism in juveniles or acromegaly in adults. The clinical complications involving cardiovascular, respiratory, and metabolic systems lead to elevated morbidity in acromegaly. Control of serum GH and insulin-like growth factor (IGF) 1 hypersecretion by surgery(More)
Many metabolites with novel structures and biological activities have been isolated from the mangrove fungi in the South China Sea, such as anthracenediones, xyloketals, sesquiterpenoids, chromones, lactones, coumarins and isocoumarin derivatives, xanthones, and peroxides. Some compounds have anticancer, antibacterial, antifungal and antiviral properties,(More)
Deranged metabolic profiles and insulin resistance (IR) have been documented in patients with prolactinomas. Few data are yet available on the apolipoprotein (apo) B/apoA-I ratio and its relationship with IR in patients with prolactinomas. This study was aimed to evaluate the level of apoB/apoA-I ratio and its association with IR in a Chinese subgroup with(More)
Hyperprolactinemia is associated with endothelial dysfunction and atherogenic risk factors, but carotid intima media thickness (IMT) has not been studied in hyperprolactinemic patients. To determine whether untreated hyperprolactinemia contributes to increased carotid IMT. Thirty-one prolactinoma patients and 60 healthy controls were respectively studied.(More)
