Filter by:The aim of this study was to determine the level of salivary estradiol, progesterone and dehydroepiandrosterone in female postmenopausal women with and without burning mouth syndrome. In all participants the quantity of unstimulated and stimulated saliva would be determined and they would fulfill self-perceived quality of life questionnaire Oral Health Impact Profile-14 (OHIP-14). Intensity of burning symptoms would be determined on visual-analogue scale grading 0-10. All data would be compared between study and control group.
Total knee arthroplasty is a procedure that relieves pain in patients with severe symptomatic osteoarthritis, but it can be associated with postoperative pain, which hinders recovery. In the previous study, we reported evidence of increased pain in patients undergoing staged total knee arthroplasty, in whom the second operated knee had greater sensitivity (tertiary hyperalgesia) as a result of the surgical injury to the first operated knee. Magnesium sulfate is an effective analgesic adjuvant for postoperative pain. Its analgesic property seems to be associated with the regulation of calcium influx into the cells, or antagonism of N-methyl-D-aspartate receptors in the central nervous system. Additionally, magnesium is known to have an anti-inflammatory effect. Inflammatory state may accompany with pain via peripheral or central sensitization. Recently, we reported that magnesium sulfate effectively attenuates not only postoperative pain but also increased pain intensity without serious adverse effects in the bilateral staged total knee arthroplasty. However, the exact mechanism regarding these effects of magnesium sulfate remains unclear. In the present study, we will investigate the analgesic mechanism of magnesium sulfate via analysis of endocrine neurosteroid levels in patients undergoing bilateral staged total knee arthroplasty.
To investigate whether the DHEA supplementation could improve mitochondrial quality in poor ovarian responders
Diminished ovarian reserve (DOR) is one the challenge in the field of artificial reproductive technology (ART) while there is still no effective resolution of this disorder. In patents with DOR, the pregnancy rate is about only 2-4%. Eventually, patients with DOR turn to adapt children instead. In recent studies, dehydroepiandrosterone (DHEAS) supplement might play a role in reverse diminished ovarian reserve and improve the prognosis of ART. Cumulus cells, formed cumulus-oocyte complex (COC) with oocyte, play a important role in folliculogenesis, oocyte maturation, oocyte meiosis and ovulation. Growing evidences disclose there are crosstalks between oocyte and cumulus cells as paracrine regulations. Aberration the crosswalks between oocytes and cumulus cells would be associated with poor prognosis of folliculogenesis and further pregnancy outcomes. In patients under ovarian hyper-stimulation protocol, the assessment of cumulus cells might be reliable indicators of folliculogenesis, embryo development, pregnancy rate and pregnancy outcomes. These genes (indicators), such as Hyaluronan synthase（HAS2), Versican (VCAN), Thrombospondin 1 (THBS1), Runt-related transcription factor 2 (RUNX2), Chromobox homolog 3 (CBX3),Tripartite motif-containing 28 (TRIM28), B-cell lymphoma 2 (BCL2)，BCL2-associated X protein (BAX). This study was assess the gene expressions of cumulus cells after the DHEAS supplement in patients with DOR under ovarian hyper stimulation protocol.
