The purpose of the study was to investigate the convergence factors to posttraumatic growth(PTG) in survivors with female urogenital neoplasm survivors. A self-reported questionnaire was completed by 141 female urogenital neoplasm survivors via e-mail from September to October, 2016. The questionnaire consisted of PTG inventory, illness intrusiveness rating scale, cancer coping, family cohesion evaluation scale, and medical outcomes study social support survey. The data were analyzed by ANOVA, Pearson-correlation coefficient, and multiple regression analysis. Total score of PTG was 84.13points and statistically significant according to age, religion, marital status and positively associated with coping, family cohesion and social support. Results of the regression analysis showed religion(${\beta}=.127$), marital status(${\beta}=.081$), coping(${\beta}=.232$) and family cohesion(${\beta}=.415$), it were explained 44.7%. This study indicates that it is important to understand general characteristics of personal. And a convergent approach is needed to promote PTG by hospital and community.

A certain group of phytochemicals such as isoflavone have been proven to act as a phytoestrogen. After thorough the study of different bibliographic herbs excluding soybeans, dates, pomegranates, and other publicized plants, three different edible herbs by Korean Food Regulation were extracted for the animal study on the effect of estrogen replacement. The herbal extract(FGF271) has been orally administered into 51 weeks old partial ovariectomized rats for 5 weeks with the different dosages of 100 and 1,000 mg/kg, respectively. It was observed that 1) serum estrogen level was increased in both 100 and 1,000 mg/kg group, 2) the distension of uterus was made dose dependently and significantly different in 1,000 mg/kg group (p.0.05) from control in the gross findings, 3) the weight of uterus was increased in 1,000 mg/kg group, and 4) the action on reproductive tissues was clear in the microscopic findings in terms of hyperplasia of endometrial epithelial cell, cystic change of submucosa, dilatation of uterus (significantly increased in 1,000 kg/mg), and follicular cystic changes in ovary. As a result, FGF271 seemed to act as a phytoestrogen by inducing the change in ovary and uterus and by increasing the serum estrogen concentration.

The present study examined the reproductive factors and food intake pattern which influence on the breast cancer risk in Daegu${\cdot}$Gyungbuk area. The case subjects were 103 patients newly diagnosed as breast cancer at Kyungpook National University Hospital. The control subjects were 159 healthy women selected by frequency matching of age and menopausal status in the same community. The survey was conducted by individual interviews using questionnaires which include general and reproductive characteristics, dietary habits, and food frequency. The odds ratios were calculated by using unconditional logistic regression after adjusting for confounding variables. The mean age of the subjects was 50 yrs, and mean body mass index was significantly high in the patient group than in the control. The patient group had a significantly higher familial history of breast cancer and a significantly shorter breast-feeding period compared to the control group. It has been found no significant relationship between extrinsic hormone use such as oral contraceptives or estrogen replacement therapy and breast cancer risk. In regard of food habits, a high preference for the cooking method of steaming rather than frying, panbroiling or roasting was significantly associated with lower relative risk of breast cancer. The higher intake frequencies of fruits for all subjects, and seaweeds only for postmenopausal subjects were related with a significantly lower relative risk of breast cancer. The results of the study suggest that the possible risk factors for the breast cancer occurrence include high BMI, family history, less breast feeding experience, preference for the cooking method of frying, and less consumption of fruits and seaweeds. This study provides an useful data for nutrition education to prevent breast cancer for the residents in Daegu${\cdot}$Gyungbuk area.

Purpose: Chemotherapy-induced nausea and vomiting (CINV) can cause severe malnutrition. However, relationships between CINV levels, non-pharmacological coping methods, and nutritional status of female cancer patients have rarely been investigated. Therefore, this study aimed to analyze their relationships in gynecologic cancer patients. Methods: Participants receiving a highly and moderately emetogenic chemotherapy were recruited. The level of CINV was assessed using a numeric rating scale. Coping methods were determined using multiple-choice self-report questionnaires and categorized into seven types for statistical analysis. Nutritional status was evaluated using biochemical and anthropometric parameters. Results: Among all the 485 patients, 200 eligible inpatients were included. Despite the administration of prophylactic antiemetics, 157 patients (78.5%) still experienced CINV, and several used nonmedically recommended coping methods, such as just enduring the symptom or rejecting food intake. A total of 181 patients (90.5%) had nutritional disorders. Although the level of CINV was indirectly related to the occurrence of nutritional disorders, patients who rejected food (${\beta}=1.57$, p=.023) and did not use physical measures (${\beta}=-1.23$, p=.041) as coping methods were under the high risk of nutritional disorders. Conclusion: Korean gynecologic cancer patients had high levels of CINV and were at high risk of nutritional disorders, which may be related to the use of nonscientific coping methods, possibly due to cultural backgrounds and lack of proper nutritional program. Therefore, developing a culturally appropriate educational program for the cancer patients with CINV is urgently needed.

The Cnidium monnieri (L.) Cusson is an annual plant distributed in China and Korea. The fruit of C. monnieri is used as a medicinal herb that is effective for the treatment of carbuncle and pain in female genitalia. However, the anti-cancer effects of CME have not yet been reported. In this study, we assessed the apoptotic effects and cell cycle arrest effects of ethanol extracts from C. monnieri on HCT116 colon cancer cells. The results of an MTT assay and LDH assay demonstrated a decrease in cell viability and the cytotoxic effects of CME. In addition, the number of apoptotic body and the apoptotic rate were increased in a dose-dependent manner through Hoechst 33342 staining and Annexin V-PI double staining. In addition, cell cycle arrest occurred at the G1 phase by CME. Protein kinase B (Akt) plays an important role in cancer cell survival, growth, and division. Akt down-regulates apoptosis-mediated proteins, such as mammalian target of rapamycin (mTOR), p53, and Glycogen Synthase kinase-3β (GSK-3β). CME could regulate the expression levels of p-Akt, p-mTOR, p-GSK-3β, Bcl-2 family members, caspase-3, and PARP. Furthermore, treatment with CME, LY294002 (PI3K/Akt inhibitor), BIO (GSK-3β inhibitor), and Rapamycin (mTOR inhibitor) showed that apoptotic effects occurred through the regulation of the AKT/mTOR/GSK-3β signaling pathway. Our results demonstrated CME could induce apoptosis and cell cycle arrest in HCT116 colon cancer cells.

Cnidium monnieri (L.) Cusson is distributed in China and Korea, and the fruit of C. monnieri is used as traditional Chinese medicine to treat carbuncle and pain in female genitalia. In this study, we examined the anti-proliferation and cell cycle arrest effects of ethanol extracts from C. monnieri (CME) in AGS gastric cancer cells. Our results show that CME suppressed cell proliferation and induced release of lactate dehydrogenase (LDH) in AGS cells by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide assay and LDH assay. Cell morphology was altered by CME in a dose-dependent manner. In order to identify the cell cycle arrest effects of CME, we investigated cell cycle analysis after CME treatment. In our results, CME induced cell cycle arrest at G1 phase. Protein kinase B (Akt) plays a major role in cell survival mechanisms such as growth, division, and metastasis. Akt protein regulates various downstream proteins such as glycogen synthase kinase-$3{\beta}$ (GSK-$3{\beta}$) and tumor protein p53 (p53). Expression levels of p-Akt, p-GSK-$3{\beta}$, p53, p21, cyclin E, and cyclin-dependent kinase 2 (CDK2) were determined by Western blot analysis. Protein levels of p-Akt, p-GSK-$3{\beta}$, and cyclin E were reduced while those of p53, p21, and p-CDK2 (T14/Y15) were elevated by CME. Moreover, treatment with CME, LY294002 (phosphoinositide 3-kinase/Akt inhibitor), BIO (GSK-$3{\beta}$ inhibitor), and Pifithrin-${\alpha}$ (p53 inhibitor) showed that cell cycle arrest effects were mediated through regulation of the Akt/GSK-$3{\beta}$/p53 signaling pathway. These results suggest that CME induces cell cycle arrest at G1 phase via the Akt/GSK-$3{\beta}$/p53 signaling pathway in AGS gastric cancer cells.
