Background: The Wnt/${\beta}$-catenin signaling pathway is an important regulator of cellular functions such as proliferation, survival and cell adhesion. Wnt/${\beta}$-catenin signaling is associated with tumor initiation and progression; ${\beta}$-catenin mutations explain only 30% of aberrant signaling found in breast cancer, indicating that other components and/or regulation of the Wnt/${\beta}$-catenin pathway may be involved. Objective: We evaluated AXIN2 rs2240308 and rs151279728 polymorphisms, and expression profiles of ${\beta}$-catenin destruction complex genes in breast cancer patients. Materials and Methods: We collected peripheral blood samples from 102 breast cancer and 102 healthy subjects. The identification of the genetic variation was performed using PCR-RFLPs and DNA sequencing. RT-qPCR was used to determine expression profiles. Results: We found significant association of AXIN2 rs151279728 and rs2240308 polymorphisms with breast cancer risk. Significant increase was observed in AXIN2 level expression in breast cancer patients. Further analyses showed APC, ${\beta}$-catenin, CK1${\alpha}$, GSK3${\beta}$ and PP2A gene expression to be associated to clinic-pathological characteristics. Conclusions: The present study demonstrated, for the first time, that AXIN2 genetic defects and disturbance of ${\beta}$-catenin destruction complex expression may be found in breast cancer patients, providing additional support for roles of Wnt/${\beta}$-catenin pathway dysfunction in breast cancer tumorigenesis. However, the functional consequences of the genetic alterations remain to be determined.

Objectives The objective of this study is to report 4 patients who had vertebral compression fracture after traffic accident, that had a complex korean medical admission treatment. Methods In this study we collected the data of traffic accident patients that came to receive intense Korean medical treatment, and had compression fracture of the lumbar spine. A total of 4 patients were studied and we compared the Visual Analogue Scale (VAS) score and the Pain-Free Walking Distance (PFWD) at addmission date and 19th day of hospitalization. Results After receiving an average of 22.25 days of admission treatment, all patients showed a significant decrease in VAS scores and increase in PFWD. The median VAS score at date of admission was 6.5 (VAS 6~9) and decreased to 3.5 (VAS 3~5), median PFWD was 37.5 (30~45) m and increased to 435 (420~450) m. Conclusions After complex korean medicine admission treatment, 4 patients with vertebral compression fracture caused by traffic accident showed decrease of pain and increase of walking distance. But there is a need for further studys to be done on treatment methods and evaluation methods.

Our study is to determine the presence of endometrial intraepithelial neoplasia (EIN) in endometrial biopsy specimens classified by the 1994 World Health Organization (WHO) criteria for endometrial hyperplasia. Endometrial biopsy specimens that were stained with hematoxylin and eosin (HE) were examined and categorized by the WHO 1994 criteria and for the presence of EIN as defined by the International Endometrial Collaborative Group. ${\beta}$-catenin expression was examined by immunohistochemistry. A total of 474 cases of HE stained endometrial biopsy tissues were reviewed. There were 379 cases of simple endometrial hyperplasia, 16 with simple atypical endometrial hyperplasia, 48 with complex endometrial hyperplasia, and 31 with complex atypical endometrial hyperplasia. Among the 474 endometrial hyperplasia cases, there were 46 (9.7%) that were classified as EIN. Of these 46 cases, 11(2.9%) were classified as simple endometrial hyperplasia, 1 (6.3%) as simple atypical endometrial hyperplasia, 6 (12.5%) as complex endometrial hyperplasia, and 28 (90.3%) as complex atypical endometrial hyperplasia. EIN was associated with a higher rate of ${\beta}$-catenin positivity than endometrium classified as benign hyperplasia (72% vs. 22.5%, respectively, P<0.001), but a lower rate than endometrial adenocarcinoma (72% vs. 96.2%, respectively, P<0.001). In benign endometrial hyperplasia, high ${\beta}$-catenin expression was noted in the cell membranes, whereas in EIN and endometrial adenocarcinoma high expression was noted in the cytoplasm. In conclusion, EIN is more accurate than the WHO classification for the diagnosis of precancerous lesions of the endometrium.

Objectives: This case report describes the effect of complex Korean medical treatment on the clinical symptoms of a patient with fibromyalgia syndrome (FMS). Methods: A 60-year-old female woman diagnosed with FMS in 2015 was prescribed Youngsunjaetong-em-hap-Sopunghwalhyeol-tang from 2 May 2023 to 20 June 2023 to reduce excessive sweating and widespread pain. With the same objective, acupuncture, moxibustion, and cupping treatment were administered from 23 May 2023 to 11 June 2023. Changes in excessive sweating and widespread pain were recorded 2 months post-treatment. Results: Treatment with Youngsunjaetong-em-hap-Sopunghwalhyeol-tang led to a considerable improvement in clinical symptoms after 2 months, especially excessive sweating and widespread pain compared to the baseline parameters of the first visit. In addition, no adverse effects, such as liver injury or decreased kidney function, were recorded during the herbal medicine treatment. Conclusion: This case report points to the use of complex Korean medical treatment as a therapeutic option for the management of FMS.

Objective : The treatment of complex intracranial aneurysms remains challenging. One approach is the application of surgical flow alteration to treat aneurysms that are neither clippable, trappable, or coilable. The efficacy and limitations of surgical flow alteration have not yet been established. Methods : Cases of complex aneurysms treated with surgical flow alteration (proximal occlusion with or without bypass, distal occlusion with or without bypass and bypass only) were included in this retrospective study. Results : Among a total of 16 cases, there were 7 giant aneurysms (${\geq}25mm$ diameter) and 9 large aneurysms (>10 mm diameter); 15 of 16 aneurysms were unruptured. There were 8 aneurysms located in the anterior circulation, while the other 8 were in the posterior circulation. Aneurysms were treated with proximal occlusion in 10 cases and distal occlusion in 5 cases; in 1 case, the aneurysm occluded spontaneously after bypass without parent artery occlusion. All but 2 cases underwent prior or concurrent bypass surgery. Complete obliteration of the aneurysm at the latest imaging follow-up was shown in 12 of 16 cases (75.0%). Bypass patency was confirmed in 13 of 15 cases (86.7%). Surgery-related morbidity developed in 3 cases (18.8%, Glasgow outcome scale of 4) and all were perforator infarctions. There were no mortalities. Conclusion : Surgical flow alteration resulted in a high rate of aneurysmal obliteration with acceptable morbidity. Although several limitations remained, it could represent an alternative method for treating complex aneurysms.

Single nucleotide polymorphisms (SNPs) are the most abundant form of human genetic variation and are a resource for mapping complex genetic traits. A genome is covered by millions of these markers, and researchers are able to compare which SNPs predominate in people who have a certain disease. The International HapMap Project, launched in October, 2002, motivated us to start the Korean HapMap Project in order to support Korean HapMap infrastructure development and to accelerate the finding of genes that affect health, disease, and individual responses to medications and environmental factors. A Korean SNP and haplotype database system was developed through the Korean HapMap Project to provide Korean researchers with useful data-mining information about disease-associated biomarkers for studies on complex diseases, such as diabetes, cancer, and stroke. Also, we have developed a series of software programs for association studies as well as the comparison and analysis of Korean HapMap data with other populations, such as European, Chinese, Japanese, and African populations. The developed software includes HapMapSNPAnalyzer, SNPflank, HWE Test, FESD, D2GSNP, SNP@Domain, KMSD, KFOD, KFRG, and SNP@WEB. We developed a disease-related SNP retrieval system, in which OMIM, GeneCards, and MeSH information were integrated and analyzed for medical research scientists. The kHapMap Browser system that we developed and integrated provides haplotype retrieval and comparative study tools of human ethnicities for comprehensive disease association studies (http://www.khapmap.org). It is expected that researchers may be able to retrieve useful information from the kHapMap Browser to find useful biomarkers and genes in complex disease association studies and use these biomarkers and genes to study and develop new drugs for personalized medicine.

The purpose of this study was to confirm the complex relationship between patient safety-medical quality and hospital management activities to observe the mediating effect of organizational culture in the relationship due to healthcare accreditation adoption. For this, we conducted a 4 weeks survey, from September 22, 2014 to October 17, 2014 to the employees of 6 hospitals that could accommodate less than 300 patients or more than 300 patients located in Daegu and Gyeongbuk. The study includes 377 participants who have worked for more than one year in the hospital. All of hospital with less than 300-beds or more than 300-beds, such as patient safety-medical quality, organizational culture, hospital management activities found a positive correlation among variables. The mediating effect of organizational culture in the relationship between patient safety-medical quality and hospital management activities was shown by the partial mediating effect and high causal effect. Therefore, these study suggest that patient safety-medical quality due to healthcare accreditation adoption has the potential to improve hospital management activities.

Precision medicine stands for 4Ps - precise, preventive, participatory, and personal; in which "precision" is important because the current modern medicine starts from "trial and error," and "one does not fit all". Current targeted therapies for cancer have changed treatment approaches and led the precision medicine; however, clinical use of liquid biopsy, using blood or other liquid specimens to characterize circulating tumor cells (CTC) or tumor genes instead of biopsies of tumor tissues, still awaits availability of more information regarding non-invasive cancer detection and characterization, prediction of treatment response, monitoring the disease course and relapse possibilities, identification of mechanisms of drug resistance, and newer pathogenesis. In this review, we will introduce the basic concept of CTC, circulating cell free DNA, and exosomes and their possible application for gastric cancer relevant with Helicobacter pylori infection.
