Tai Chi for Lower Urinary Tract Symptoms and Quality of Life in Elderly Patients with Benign Prostate Hypertrophy: A Randomized Controlled Trial
Tai chi exercise has been recommended as suitable for the improvement of health in the elderly. The purpose of this study was to investigate the effects of tai chi on lower urinary tract symptoms (LUTSs), quality of life (QoL), and sex hormone levels in patients with benign prostate hypertrophy (BPH). The elderly patients with BPH were randomized to receive tai chi or usual care. Fifty-six participants were randomized into either the tai chi group (n = 28) or the control group (n = 28). After 12 weeks of treatment, the tai chi group showed significant improvement in LUTS and QoL. There was a significant effect of tai chi on testosterone but no significant effect on insulin or glucose. No serious adverse events were observed during the study period. In conclusion, our results suggest that 12 weeks of tai chi may improve LUTS and QoL in elderly patients with BPH
Antiproliferative effect of gold(I) compound auranofin through inhibition of STAT3 and telomerase activity in MDA-MB 231 human breast cancer cells
Signal transducer and activator of transcription 3 (STAT3) andtelomerase are considered attractive targets for anticancertherapy. The in vitro anticancer activity of the gold(I) compoundauranofin was investigated using MDA-MB 231 human breastcancer cells, in which STAT3 is constitutively active. In cellculture, auranofin inhibited growth in a dose-dependent manner,and N-acetyl-L-cysteine (NAC), a scavenger of reactive oxygenspecies (ROS), markedly blocked the effect of auranofin.Incorporation of 5-bromo-2â-deoxyuridine into DNA andanchorage-independent cell growth on soft agar were decreasedby auranofin treatment. STAT3 phosphorylation and telomeraseactivity were also attenuated in cells exposed to auranofin, butNAC pretreatment restored STAT3 phosphorylation andtelomerase activity in these cells. These findings indicate thatauranofin exerts in vitro antitumor effects in MDA-MB 231 cellsand its activity involves inhibition of STAT3 and telomerase.Thus, auranofin shows potential as a novel anticancer drug thattargets STAT3 and telomerase.

The Effect of Calcipotriol on the Expression of Human β Defensin-2 and LL-37 in Cultured Human Keratinocytes
Background. Vitamin D has been reported to regulate innate immunity by controlling the expression of antimicrobial peptides (AMPs). Objective. We investigated the effect of calcipotriol on the expression of AMPs in human cultured keratinocytes. Methods. Keratinocytes were treated with lipopolysaccharide (LPS), TNF-ι, Calcipotriol and irradiated with UVB, cultured, and harvested. To assess the expression of human beta defensin-2 and LL-37 in the control group, not exposed to any stimulants, the experimental group was treated with LPS, TNF-ι, or UVB, and another group was treated again with calcipotriol; reverse transcriptase-polymerase chain reaction, Western blotting, and immunohistochemical staining were performed. Results. In the experimental group treated with LPS, UVB irradiation, and TNF-ι, the expression of β-defensin and LL-37 was increased more than in the control group and then decreased in the experimental group treated with calcipotriol. Conclusions. Calcipotriol suppressed HBD-2 and LL-37, which were stimulated by UVB, LPS, and TNF-ι
Enhancement of angiogenic and vasculogenic potential of endothelial progenitor cells by haptoglobin
AbstractEndothelial progenitor cells (EPCs) were transfected with the haptoglobin (Hp) gene to investigate the effect of Hp on cell function. Hp potentiated the gene expression of various pro-angiogenic factors in the EPCs. The Hp-modified EPCs also increased in vitro tube formation on Matrigel compared with control cells. In hindlimb ischaemia models, HpâEPCs showed a greater ability for improving blood perfusion and recovery from ischaemic injury. These results indicate that Hp improves EPC function in neovasculogenesis, which suggests that ex vivo modification of EPCs with the Hp gene can be applied to the treatment of vascular damage
Hyaline Vascular-Type Castleman Disease Presenting as an Esophageal Submucosal Tumor: Case Report
Castleman disease is a relatively rare disorder of lymphoid tissue that involves the gastrointestinal tract in a variety of clinical and pathologic manifestations. A submucosal location has never been described in the medical literature. We report a case of esophageal Castleman disease involving thesubmucosal layer in a 62-year-old man, which was confirmed on pathology. Esophagography and CT demonstrated an intramural tumor, and a leiomyoma or leiomyosarcoma was suspected based on the known incidence of such tumors
