OBJECTIVES: Cadherin/catenin adhesion complex is fundamentally involved in epithelial cancer invasion and metastasis. E-cadherin and EGFR colocalize on the basolateral membrane of epithelial cell and EGF down-regulate E-cadherin expression. In the invasion and metastasis of cancer, E-cadherin expression is decreased and growth factors receptor is overexpressed. The present study was aimed to find the role of E-cadherin, beta-and gamma-catenin, growth factors and its receptors in cervical cancer cell lines. METHODS: The cervical cancer cell cultures were treated with different time duration of EGF 30 ng/ml and TGF-a 10 ng/ml(0, 10 min, 20 min, 30 min, 1 hr, 2 hr, 4 hr, 8 hr, 24 hr). The change in cancer cell morphology and the changes in E-cadherin, beta- and gamma-catenin, EGFR and activated EGFR expression were studied with a western blot analysis and an immunoprecipitation. RESULTS: Through a western blot analysis, E-cadherin 120 kDa band and EGFR 170 kDa band were expressed in CaSki, HT-3 and ME-180 cell line, which showed epithelial contact growth. 1n these 3 cell lines, expression of E-cadherin did not decrease with time dependent manner. after the treatment of EGF and TGF- alpha. The expression of EGFR decreased and activated EGFR expression increased in 30 minutes to 1 hour but decreased subsequently. When the cells treated with EGF, there were no change in beta-and gamma-catenin expression with there dependent manner. The tyrosine phosphorylation of beta-and gamma-catenin increased in 30 minutes to 1 hour but decreased subsequently with activated EGFR. CONCLUSION: This study showed that an activated EGFR which has involved with tyrosine phosphorylation of beta- and gamma-catenin influenced by growth factors rather than expression of E-cadherin, has a role in the invasion and metastasis of the cervical cancer.

BACKGROUND: This study researched the relationship between shift work and one of its relevant health problems, functional gastrointestinal disorders. The study targeted nurses working at a university hospital, and compared the differences in gastrointestinal disorders of shift workers and non-shift workers and identified causes that significantly influence these symptoms. METHODS: In August 2013, a self-report survey was conducted on nurses working at a university hospital. Among those sent out, 1,201 responded and 851 were used for the final analysis. RESULTS: It was shown that the frequency of gastrointestinal disorders in shift workers was 1.881 times higher than that of non-shift workers. Factors that influenced gastrointestinal disorders included age, marital status, work duration, type of employment, job satisfaction, and perceived health status. Gastrointestinal disorders were seen more often with older age, being married, longer duration of employment, non-regular worker, low job satisfaction, bad perceived health status, and shift works. CONCLUSIONS: To prevent gastrointestinal disorders in nurses who work shifts, a health checkup system should be in place for clinical nurses who are of older age and have longer employment records. To decrease the causes of gastrointestinal disorders, campaigns suggesting regular diet and quitting alcohol use should be held consistently. Also, a category related to gastrointestinal disorders should be added to the employee health checkup for nurses with long work experience.

PURPOSE: The purpose of this study was to compare the premenstrual syndrome (PMS) and the relationships among PMS, perfection, and anxiety in nursing college students and general college students. METHODS: The questionnaire survey was carried out with a convenience sample of 215 college students. The MDQ (Menstrual Distress Questionnaire), APS-R (Almost Perfect Scale-Revised), STAI (State and Trait Anxiety Inventory) were used. The data were collected from June to October, 2011. Data analysis included frequency, chi2-test, t-test, and Pearson correlation. RESULTS: There were significant differences in PMS and perfection but there not in anxiety between nursing college students and general college students. There were significant correlations among PMS, perfection and anxiety in nursing college students, and there were significant correlations among PMS and anxiety in general college students but not significant correlations among PMS and perfection. CONCLUSION: The findings suggest that to provide effective interventions for PMS in college students, it is necessary to design nursing interventions that consider perfection and anxiety.

OBJECTIVES: Interleukin-6 is a pleiotrophic cytokine that is not only a mediator in major immunologic reactions but also a growth factor of keratinocytes. We studied IL-6 mRNA expression in cervical cancer, CIN and normal cervix. And we questioned whether its expression is related to cervical carcinogenesis and other prognostic factors. METHODS: The normal cervical and cervical cancer tissues were taken from healthy women (n=16), and the patients with CIN (n=36) and cervical cancer (n=36). The IL-6 mRNA expression was examined by quantitative competitive PCR after polymerase chain reaction amplification of reverse transcriptase copies of RNA transcripts (RT-PCR). RESULTS: There was no statistically different among cervical cancer, CIN and normal cervix (p>0.05). The IL-6 mRNA expression was not different according to the grades of CIN. Its expression was not correlated with the stage of cervical cancer, size of tumor, and histopathologic type (p>0.05). CONCLUSION: These results suggested that IL-6 mRNA expression might not be associated with the cervical carcinogenesis and prognosis of cervical cancer.

PURPOSE: This study was conducted to assess predictor variables of husbands in multicultural families and examine the relationship among variables after setting up a hypothetical model including influencing factors, so as to provide a framework necessary for developing nursing interventions of domestic violence. METHODS: The participants were 260 husbands in multicultural families in four cities in Korea. Data were analyzed using SPSS 22.0 and AMOS 20.0. RESULTS: Self-control, social support, family of origin violence experience and stress on cultural adaptation directly affected to dysfunctional communication, and the explanatory power of the variables was 64.7%. Family of origin violence experience in domestic stress on cultural adaptation, and dysfunctional communication were directly related to domestic violence in multicultural families, and the explanatory power of the variables was 64.6%. We found out that all variables in the model had mediation effects to domestic violence through dysfunctional communication. In other words, self-control and social support had complete mediation effects, and family of origin violence experience in domestic violence and stress on cultural adaptation had partial mediation effects. CONCLUSIONS: The variables explained in this study should be considered as predictive factors of domestic violence in multicultural families, and used to provide preventive nursing intervention. Our resutls can be taken into account for developing and implementing programs on alleviating dysfunctional communication in multicultural families in Korea.

PURPOSE: The study was to analyze clinical outcomes and risk factors of for complications associated with the hip fracture surgery in the elderly before and after interdisciplinary treatment. METHODS: A retrospective method was used to investigate the general and therapeutic characteristics, frequency of complications and clinical outcomes. The subjects of the study were 553 patients who underwent hip fracture surgery from January, 2009 to December, 2014. RESULTS: The interdisciplinary group was older and less likely to walk independently even before the fracture than a usual care group. The incidence of complications was higher in the interdisciplinary group than the usual care group. The prevalence of complications in both groups was 66.5%. Multivariate logistic regression analysis showsed that the risk factors for complications of hip fracture surgery were as follows: advanced age, stroke, Parkinson disease, time interval from emergency room to operation, pre & post ambulatory status, American Society of Anesthesiologists (ASA) classification quality of postop intensive care unit (ICU) care and foley indwelling. CONCLUSION: This study has implications in that it recognized the necessity for interdisciplinary treatment and provided the basic base data for nursing intervention of the elderly patients who underwent hip fracture surgery.

Mirizzi syndrome refers to a gallstone impacted in the gallbladder neck and this exerts pressure on the adjacent common hepatic duct, which produces inflammatory stricture and eventual penetration of its lumen. Making the preoperative diagnosis of Mirrizzi syndrome is very important. But if it cannot be diagnosed before an operation, intraoperative recognition is also important for surgeons. We experienced two patients who were diagnosed with this syndrome at the time of operation.

PURPOSE:Insulin-like growth factor-I(IGF-I) is an essential anabolic factor for postnatal rat brain development and IGF-I expression is highly abundant during the first 21 days, critical growth period. Hypoxic-ischemic brain insults occurring during the perinatal period result in neuronal necrosis and permanent brain damage. To investigate the regulation of the action of IGF-I in response to such a hypoxic insult, we examined the gene expression of IGF-I and IGFBP-5 during the first 72 hr after hypoxic-ischemic injury in immature rat brain. METHODS:Ligation of the right carotid artery of 7-day-old rats was followed by 2 hour exposure to 8% oxygen to produce severe hypoxic brain damage. Using reverse transcriptase-polymerase chain reaction(RT-PCR), the expression of IGF-I mRNA and IGFBP-5 mRNA was determined in both hypoxic and control brains at post 1, 4, 12, 24, 48 hr and 72 hr after hypoxic-ischemic insult. RESULTS:The IGF-I mRNA and IGFBP-5 mRNA expression of hypoxic brain were not different from those of controls at 1 hr of recovery but IGF-I mRNA expression was decreased rapidly at post 4 hr, this decrease more pronounced at 12 hr of recovery. IGF-I mRNA and IGFBP-5 mRNA expression were increased at 48 hr and 24 hr of recovery, respectively and both IGF-I mRNA and IGFBP-5 mRNA expression showed similar level of controls at 72 hr of recovery. CONCLUSION: Out findings suggest that IGF-I play a important role in both neuronal loss and repair process following hypoxic-ischemic brain injury and IGFBP-5 is also strongly involved in the repair of damaged brain tissue by mediating IGF-I action.

The purpose of this study was to investigate the influence of regular stretching exercise for 1 year on health related fitness of the elderly women. We also determined whether the weekly stretching exercise sessions followed by intensive stretching exercise program was beneficial to maintain the altered health related fitness status. The thirty elderly women (F, 80.1+/-6.6 yr) were participated in this study. Subjects had no serious orthopedic problems. During the study period, they did not perform any regular physical activity beside the stretching exercise. The 1 year stretching exercise programs included 3 days/week stretching exercise session for the first 12 weeks followed by 1 day/week stretching exercise for rest of the study period. The subjects were tested 6 categories of health related fitness factors which included % body fat, flexibility, hand grips, back strength, balance, and agility. The summary of the results of this study were as followed: 1) There were significant increase in FFM and slightly decrease in %BF and WHR after the 3 days/wk stretching exercise program. However, there were significant decrease in FFM and WHR after the 1 day/wk stretching exercise program (p<.05). 2) There were significant increase in flexibility, hand grip strength (Rt.) and balance after the 3 days/wk stretching exercise (p<.05) while hand grip strength (Lt.) and back strength were slightly increase after the exercise. However, there were significant decrease in hand grip strength (both) and reaction time after 1 day/wk stretching exercise program while flexibility, back strength, and balance were slighly decrease after the program. In conclusion, this study showed that the 3 days/wk stretching exercise for 12 weeks result in significant increase of all health related fitness factors (p<.05). However, it showed that some of the HRF factors were decreased after the weekly stretching exercise unexpectedly.
