Objective: The purpose of this study is to investigate the combined effects of exemestane and aspirin on MCF-7 human breast cancer cells. Methods: Antiproliferative effects of exemestane and aspirin, alone and in combination, on growth of MCF-7 human breast cancer cells were assessed using the MTT assay. Synergistic interaction between the two drugs was evaluated in vitro using the combination index (CI) method. The cell cycle distribution was analyzed by flow cytometry and Western blotting was used to investigate the expression of cyclooxygenase-1, cyclooxygenase-2 and Bcl-2. Results: MTT assays indicated that combination treatment obviously decreased the viability of MCF-7 human breast cancer cells compared to individual drug treatment (CI<1). In addition, the combination of exemestane and aspirin exhibited a synergistic inhibition of cell proliferation, significantly arrested the cell cycle in the $G_0/G_1$ phase and produced a stronger inhibitory effect on COX-1 and Bcl-2 expression than control or individual drug treatment. Conclusion: These results indicate that the combination of exemestane and aspirin might become a useful method to the treatment of hormone-dependent breast cancer. The combination of the two inhibitors significantly increased the response as compared to single agent treatment, suggesting that combination treatment could become a highly effective approach for breast cancer.

Purpose: This study was to develop an effective evaluation tool for evaluation of hypertension prevention and management program(HPMP) in community health posts (CHPs). Method: Evaluation tool composed from the literature review, the field visiting, and the in-depth interviews with the community health practitioners. Result: The evaluation tool had four domains, each with different maximum points:, hypertension prevention (35), hypertension management (40), environment of the CHPs(10), and evaluation system of the HPMP(15). The first domain was hypertension prevention with sub-domains of health education, and early detection of patients with hypertension. The second domain was hypertension management with sub-domains of management of health records of patients, education and counseling, and treatment and follow-up of patients. The third domain was the environment of the CHPs with subdomains of accessibility of CHPs to residents, accessibility of general health data to the public, and availability of health information to the public by multimedia. The fourth domain was the evaluation system of the HPMP with the subdomains of planning of program, formative evaluation, process evaluation, and summative evaluation. Conclusion: The newly developed evaluation tool will contribute not only to plan and set goals for evaluation of HPMP in CHPs.

Pediatric obesity has rapidly increased globally over the past few decades, including in Korea. We aimed to discuss trends in the prevalence of pediatric obesity and effective prevention strategies. Its prevalence has markedly increased in most high-income nations. According to recent reports, this increase has slowed in developed countries, but the levels remain alarmingly high. In Korea, the rate of pediatric obesity has surged notably since the 1990s; however, since the 2000s, this increase has become more gradual. According to recently published 2017 growth charts, the prevalence of pediatric obesity in Korea varies slightly depending on the data source. The National School Health Examination data showed that pediatric obesity gradually increase from 11.5% in 2014 to 15.1% in 2019, and after the coronavirus disease 2019 pandemic, it sharply increased to 19% in 2021. Based on data from the Korea National Health and Nutrition Examination Survey, the prevalence of pediatric obesity gradually increased from 10.8% in 2017 to 13.6% in 2019. This trend, which accelerated sharply to 15.9% in 2020 and 19.3% in 2021, was especially severe in boys and older children. Pediatric obesity not only affects health during childhood but also increases the risk of developing obesity and associated health conditions in adulthood. Despite ongoing research on treatment options, obesity prevention and control remain challenging. Hence, prioritizing early intervention and prevention of pediatric obesity through healthy eating habits and lifestyles is crucial. This requires intervention at the individual, family, school, and community levels.

Objective: This work aimed to evaluate the safety and clinical efficacy of transcatheter arterial chemoembolization (TACE) combined with c-arm cone-beam CT guided synchronous radiofrequency ablation (RFA) in treatment of large hepatocellular carcinoma (HCC). Methods: 21 patients with large HCC were studied from January 2010 to March 2012. TACE combined with synchronous C-arm cone-beam CT guided RFA were performed on a total of 25 lesions. Conventional imaging examination (CEUS, enhanced CT or MRI) and AFP detection were regularly conducted to evaluate the technical success rate of combined treatment, complications, treatment response, time without disease recurrence and survival rate. Results: The technical success rate of combined treatment was 100%, without any significant complication. After 1 month, there were 19 cases with complete response and 2 cases with partial response, with an complete response rate of 90.4% (19/21) and a clinical effective rate of 100% (21/21). The complete response rates of single nodular lesions (100%, 17/17) was significantly higher than that of multiple nodular lesions (50%, 2/4) (P<0. 05). During 2 to 28 months of follow-up, in 19 cases with complete response, the average time without disease recurrence was $10.8{\pm}6$ months. The total survival rates of 6, 12 and 18 months in 21 patients were 100%, respectively. Conclusion: TACE combined with synchronous C-arm CT guided RFA is safe and effective for treatment of large HCC. The treatment efficacy for single nodular lesion is better than that for multiple nodular lesions.

Objectives : Virus infection through the respiratory tract causes various inflammatory diseases such as pneumonia, cystic fibrosis, and obstructive pulmonary disease, causing enormous social damage. Therefore, it is very important to develop a treatment and prevention of infectious diseases. In this study, we investigated the effect of water extracts of Liriope muscari (WELM), known to improve lung function, on the inflammatory response of lung carcinoma cell line A549 cells induced by the viral double stranded RNA mimetic Polyinosinic:polycytidylic acid (Poly I:C). Methods : The cell viability by WELM treatment was analyzed using MTS assay in A549 cells. After inducing an inflammatory response to WELM-treated A549 cells with Poly I:C, the degree of apoptosis was confirmed through bright field microscopy. Interferon beta (IFN-β) mRNA expression level in A549 cells was analyzed by quantitative reverse transcription PCR (qRT-PCR). Results : WELM treatment has no significant effect on cell viability of A549 cells. We confirmed that pre-treatment of WELM effectively reduces the Poly I:C-induced apoptotic cell death in A549 cells. In addition, it was confirmed that the mRNA expression level of IFN-β, a pro-inflammatory cytokine increased by Poly I:C treatment, was significantly suppressed by WELM treatment in A549 cells. Conclusions : These results provide the evidence that WELM is effective at inhibiting inflammation on respiratory viral infections and suggest that Liriope muscari might be a valuable natural substance in the prevention and treatment of infectious diseases.

This study was carried out to compare the efficacy of sodium carboxymethyl cellulose (SCMC) with the combination of low molecular weight heparin (LMWH) and SCMC for the prevention of postoperative adhesions in the dog. After laparotomy, abrasions were made on the surface of ileal serosa in 17 dogs. The animals were randomly divided into the control group (N = 5) which received no treatment, the SCMC-treated group (N = 6), and the SCMC ＆ LMWH-treated group (N = 6). Hematologic values were monitored before laparotomy and 1, 4, 7, 10 and 14 days after laparotomy. The location and score of adhesion were assessed at second laparotomy 3 weeks later, Although the mean adhesion score both in the SCMC-treated group (7.17${\pm}$1.17) and in the SCMC & LMWH-treated group (4.50${\pm}$1.38) was found to be significantly lower than that in the control group (9.40${\pm}$0.89) (p<0.01 and p＜0.01, respectively), more favorable adhesion prevention was achieved in the SCMC ＆ LMWH-treated group in comparison with the SCMC-treated group without any hemor-rhagic complications (p<0.01). This study could conclude that SCMC ＆ LMWH are highly effective in prevention against postoperative adhesion in the dog.

A Study on Scoliosis Milwaukee Brace , Therapeutic Exercise -Oh, Kuyung- Hwan Scoliosis implies an appreciable lateral deviation in the spine. There are numerous theories of the etiology of scolisosis. but the true causative factors remain unknown ;thus this affliction currently cannot be prevented. Treatment essentially consists of early recognition, correction of existing curves, and prevention of the further progression of the curves . Tremendous strides are being made in the treatment of severe scoliosis but the desire for early nonoperative treatment is of paramount important. Many conservative nonoperative procedures have been advocated. Among th-em .Milwaukee brace and therapeutic exercise are the most effective ones .
