Background Among non-hormonal treatments, herbal products are frequently used by women. Korean red ginseng (KRG) is one of the popular herbal medicines. KRG could be one option for relieving menopausal symptoms. However, there are still concerns about the safety for long-term use. In order to be used for alleviating menopausal symptoms, the safety of KRG on breast must be ensured. The purpose of this study was to investigate the effects of KRG on breast cells. Methods MCF-7 and MCF-10A cells were treated with different concentrations of KRG extracts for 48 h. Cell viability was evaluated by MTT assay, and apoptosis by flow cytometry. The expression of apoptosis-related proteins was determined by western blot analysis and estrogen receptor (ER) affinity by ER binding assay. Results KRG extract inhibited growth and induced apoptosis of both MCF-7 and MCF-10A cells in dose-dependent manner. KRG extract increased the expression of pro-apoptotic proteins BAX, BAK, and BAD and decreased the expression of anti-apoptotic proteins Bcl-2 and Bcl-XL in both cells. The expressions of Fas and FasL were increased in lower doses, but decreased in higher doses in both cells. Activities of caspase-3, -8 and -9 increased in MCF-10A, while caspase-8 and -9 showed increase in MCF-7. Competition of KRG to E2 was significant in MCF-7 as KRG dose increased, whereas ER binding was hardly shown in MCF-10. Conclusion KRG induced apoptosis via extrinsic and intrinsic pathway in MCF-7 breast cancer cells and MCF-10A non-malignant cells. KRG may be safely used with regard to breast cancer risk in postmenopausal women to reduce the vasomotor symptoms.

Objective To describe the clinical outcomes of frozen-thawed embryo transfer (FET) with artificial preparation of the endometrium, using a combination of estrogen (E2) and progesterone (P4) with or without a gonadotropin-releasing hormone agonist (GnRHa), and the modified natural cycle (MNC) with human chorionic gonadotropin (hCG) trigger. Methods In this retrospective study, we evaluated 187 patients during 3 years (February 2012-April 2015). The patients were allocated to the following treatment groups: group A, comprising 113 patients (181 cycles) who received GnRHa+E2+P4; group B, comprising 49 patients (88 cycles) who received E2+P4; and group C, comprising 25 patients (42 cycles) who received hCG+P4. The inclusion criteria were regular menstrual cycles (length 24-35 days) and age 21-45 years. Results The primary outcome of the study - implantation rate (IR) per embryo transferred - was not statistically different among the 3 groups. Similar results were found for the IRs with fetal heartbeat per embryo transferred (68/181 [37.6%] in group A vs. 22/88 [25.0%] in group B vs. 14/42 [33.3%] in group C) and for the live birth rates (LBRs) per embryo transferred (56/181 [30.9%] in group A vs. 18/88 [20.5%] in group B vs. 11/42 [26.2%] in group C). Conclusion Although the pregnancy outcomes were better in the hormone therapy with GnRHa group, hormone therapy FET with GnRHa for pituitary suppression did not result in significantly improved IRs and LBRs when compared with hormone therapy FET without GnRHa or MNC FET.

OBJECTIVES Menopause is a natural aging process causing estrogen deficiency, accelerating atherogenic processes including dyslipidemia. Prevalence of thyroid dysfunction is also high in postmenopausal women, and it is known to elevate the risk of cardiovascular disease (CVD). Therefore, we are to study on the associations in between serum thyroid stimulating hormone (TSH) and prevalence of CVD in postmenopausal women who have normal thyroid function. METHODS We performed a retrospective review of 247 Korean postmenopausal women who visited the health promotion center from January, 2007 to December, 2009. Postmenopausal women with normal serum TSH were included in the study. Coronary atherosclerosis was assessed by 64-row multidetector computed tomography. RESULTS In multiple linear regression analysis, serum TSH was associated with serum triglyceride (TG) (β = 0.146, P = 0.023). In multiple logistic regression analysis, increasing age and serum TSH were associated with an increased risk of coronary atherosclerosis in euthyroid postmenopausal women (odds ratio [OR] = 1.107 [1.024-1.197], P = 0.011 and OR = 1.303 [1.024-1.658], P = 0.031, respectively). CONCLUSIONS It revealed that significant predictor of serum TSH was serum TG, and increasing age and TSH were found to have associations with an increased risk of coronary atherosclerosis in euthyroid postmenopausal women. Screening and assessing risks for CVD in healthy postmenopausal women would be helpful before atherosclerosis develops.

This study aimed to evaluate the effects of ketorolac, a commonly used non-steroidal anti-inflammatory drug (NSAID) as patient controlled intravenous infusion analgesia (PCIA) for the patients underwent radical cystectomy (RC) due to bladder cancer regarding post-operational indices of recovery. Total seventy patients who underwent radical cystectomy for the treatment of bladder cancer were included in the study. 35 patients received ketorolac as PCIA (NSAIDS group) and 35 patients had morphine infusion as PCIA (morphine group). Pain intensity, bowel function recovery and length of hospital stay were evaluated. Early postoperative complications were analyzed according to surgical types (robot RC vs. open RC). Demographics were similar between two groups. NSAIDS group showed a significant reduction in postoperative vomiting (p = 0.001), time to flatus (p = 0.028), time to first bowel movement (p = 0.001) and time to first clear liquid diet (p = 0.002) compared with morphine group. No statistically significant differences were observed between two groups regarding length of hospitalization, and postoperative complications. For 48 hours after RC, pain relief was slightly better in morphine group (p

Objective The purpose of this study was to evaluate the effectiveness of scheduled ramosetron injections for controlling postoperative nausea and vomiting (PONV) after single-port access total laparoscopic hysterectomy (SPA-TLH). Methods Ninety patients who underwent SPA-TLH at the Korean National Health Insurance Service Ilsan Hospital between June 2013 and July 2014 were enrolled in this prospective, randomized, double-blinded, placebo-controlled study. The patients were divided into 2 groups as follows: the ramosetron group (0.3 mg intravenously [IV]; n=45) and the placebo group (normal saline IV; n=45). Both groups received their respective injections 12 and 24 hours post surgery. The incidence and severity of PONV (numerical rating scale, 0–10), and the use of rescue antiemetics post surgery were evaluated. Results Demographic and perioperative statistically significant differences were not observed between the 2 groups. The incidence of PONV in the ramosetron and placebo groups was 46.7% and 51.1%, respectively (P=0.51). We found significant differences in the severity of PONV between the 24- to 48-hour postoperative periods in both groups (ramosetron group, P=0.04 and placebo group, P=0.03). The use of rescue antiemetics was significantly lower in the ramosetron group than in the placebo group (P=0.02). Conclusion After general anesthesia, scheduled injections of ramosetron 12 and 24 hours after SPA-TLH reduced the severity of PONV and the use of rescue antiemetics. Administration of ramosetron can be considered not only immediately after SPA-TLH but also during the first 24-hour recovery period. Trial Registration ClinicalTrials.gov Identifier: NCT 02011659

Background Serum ferritin levels increase in postmenopausal women, and they are reported to be linked to major health problems. Here, we investigated the association between serum ferritin levels and insulin resistance (IR) in postmenopausal women. Methods A total of 6632 healthy Korean women (4357 premenopausal and 2275 postmenopausal) who participated in the Korean National Health and Nutrition Examination Survey (KNHANES) in 2007–2010 were enrolled in the study. Serum ferritin values were divided into six groups for the premenopausal and postmenopausal groups. IR and obesity indices were evaluated according to the six serum ferritin groups. Statistical analysis was carried out using SAS software, version 9.2 (SAS Institute Inc., Cary, NC, USA). Results The association between the IR indices and ferritin groups had a higher level of statistical significance in the postmenopausal group than in the premenopausal group. In addition, for the postmenopausal group, the estimates increased significantly in the sixth ferritin group compared to those in the first ferritin group. However, the association between the obesity indices and ferritin levels was not significantly different between the premenopausal and postmenopausal groups. Conclusion Elevated serum ferritin levels were associated with an increased risk of insulin resistance in postmenopausal women.
