Purpose: To study the expression of angiogenin-2 (Ang-2) and its receptor Tie-2 in colorectal cancer and discuss the possible mechanisms behind this process. Materials and Methods: Using the streptavidin-peroxidase (SP) immunohistochemical method, paraffin sections from 100 colorectal cancer samples and 10 samples from tumor-adjacent normal tissue (> 2 cm from the edge of the gross tumor) were tested for protein expression of Ang-2, Tie-2, PI3K, and AKT. Reverse transcription-polymerase chain reaction and Western blots were further used to measure expression of the 4 genes and proteins in 20 freshly-resected colorectal cancer samples and tumor-adjacent normal tissues. Results: In colorectal cancer tissues, the expression of the Ang-2, Tie-2, PI3K, and AKT genes and their proteins was significantly higher than in tumor-adjacent normal tissues. Protein expression in poorly-differentiated adenocarcinoma was higher than that in well and moderately differentiated adenocarcinoma. According to Duke's classification, the protein expression in Stages C and D was significantly higher than that in Stages A and B. In the group with lymphatic metastasis, the protein expression was higher than that without lymphatic metastasis. Conclusions: In colorectal cancer, the expression of the Ang-2, Tie-2, PI3K, and AKT genes and their proteins is markedly higher than those in tumor-adjacent normal tissues. No correlation was observed between protein expression and gender, location, or histologic type. Correlations did exist between protein expression and differentiation level, stage of Duke's classification, and lymphatic metastasis; in colorectal cancer tissues with lower differentiation levels, higher stages of Duke's classification, and lymphatic metastasis, the expression of all 4 proteins was higher. The study of their expression patterns and relationships with aggression and metastasis will provide a valuable experimental foundation for assessing prognosis and targeted therapy of colorectal cancer.

최근 정밀한 암 치료를 위해 방사선 치료기술이 강도변도 방사선치료, 영상유도 방사선치료 등의 눈부신 발전을 이루어 왔다. 2000년 이후로는 치료실에서 환자의 실제 치료위치를 정확히 파악하여 정밀한 치료를 가능하게 하는 영상 유도방사선 치료기술이 사용되고 있으며 가장 중요한 기술 중 하나가 방사선 치료 전에 다양한 방법의 의료 영상을 이용하여 환자의 치료 위치를 보정하는 것으로 가장 최근의 기술로는 선형가속기에 장착된 2차원 평면검출기를 이용한 콘빔CT (Cone Beam CT: CBCT)가 사용되고 있다. 본 연구에서는 기존의 CBCT의 "half fan" 조건에서 획득된 projection영상을 이용하여 360도 회전한 모든 영상이 아닌 제한된 각도에서 획득한 투사영상을 이용하여 환자의 해부학적 정보를 볼 수 있는 디지털 영상합성영상(Digital Tomosynthesis) 기술을 구현하였고 실제 위치교정을 위해 촬영된 환자 데이터를 이용하여 방사선 치료 환자 위치 교정을 위한 효용성을 검증하였다. 그 결과 동일 단층상에서의 해부학적 정보 표현에서 CBCT 영상과 비교하였을 때 유사성을 보였고 선량적인 측면에서 우월성을 나타냈다. 이러한 DTS의 장점을 극대화 하고 최적화가 이루어진다면 방사선 치료 위치 보정용으로 CBCT를 대체 할 수 있는 기술이 될 수 있을 것이라 기대한다.

Breast cancer (BCa) is the leading type of cancer in Mexican women. Genetic factors, such as single nucleotide polymorphisms (SNP) of P450 system, have been reported in BCa. In this report, and for the first time in the literature, we analyzed the rs3735684 (7021 G>A), rs11553651 (15016 G>T) and rs56195291 (60020 C>G) polymorphisms in the CYP2W1, 4F11 and 8A1 genes in patients with BCa and in healthy Mexican women to identify a potential association between these polymorphisms and BCa risk. Patients and controls were used for polymorphism analysis using an allelic discrimination assay with TaqMan probes and confirmed by DNA sequencing. Links with clinic-pathological characteristics were also analyzed. Statistical analysis was performed using the standard ${\chi}^2$ or Fisher exact test statistic. No significant differences were observed in the distributions of CYP2W1 (OR 8.6, 95%CI 0.43-172.5 P>0.05; OR 2.0, 95%CI 0.76-5.4, P>0.05) and CYP4F11 (OR 0.3, 95%CI 0.01-8.4 P>0.05) genotypes between the patients and controls. Only the CYP8A1 CC genotype was detected in patients with BCa and the controls. All polymorphism frequencies were in Hardy-Weinberg Equilibrium (HWE) in the controls (P>0.05). We found a significant association between BCa risk and smoking, use of oral contraceptives or hormonal replacement therapy (HRT), obesity, hyperglycemia, chronic diseases, family history of cancer and menopausal status in the population studied (P<0.05). Tobacco, oral contraceptive or HRT, chronic diseases and obesity or overweight were strongly associated with almost eight, thirty-five, nine and five-fold increased risk for BCa. Tobaco, obesity and hyperglycemia significantly increased the risk of BCa in the patients carrying variant genotypes of CYP2W1 (P<0.05). These results indicate that the CYP2W1 rs3735684, CYP4F11 rs11553651 and CYP8A1 rs56195291 SNPs are not a key risk factor for BCa in Mexican women. This study did not detect an association between the CYP2W1, 4F11 and 8A1 genes polymorphisms and BCa risk in a Mexican population. However, some clinico-pathological risk factors interact with CYP2W1 genotypes and modifies susceptibility to BCa.

Major purposes of this study were to investigate the administration patterns of analgesics and sedatives in SICU and to identify the factors influencing the use of prn analgesics and sedatives by ICU nurses. The sample of this descriptive study was 50 adult patients in SICU and 53 ICU nurses. Patient's medical records were reviewed to investigate names, doses, the routes of administration, the interval of administration, and the type of prescription of sedatives and analgesics administered. Study medications were narcotics, hypnotics, and antipsychotics. To identify the factors influencing the use of prn analgesics and sedatives, 53 ICU nurses checked 9 items, and rank them from first to fifth. The selection of items was based on the previous studies and the experience of the investigator. The results of the study are as follows: 1. The mean age of the subjects was 53 years, 24 patients out of 50 subjects had received mechanical ventilation therapy. Most of the patients received neurosurgeries and abdominal surgeries. 2. For 4 days, 13 total study medications and combination of these were administered to the patients. Commonly prescribed drugs were Ketoprofen and Midazolam. Twenty six to fourty two percent of the patients did not receive any drugs for at least one day during the four days. 3. On the average, the study drugs were administerd 1.4 to 2.6 times per day during 4 days. 4. More than 50 percent of the prescription was as-needed (prn) except those of the POD 3. Fourteen percent of the patients did not have any prescription for sedation and pain control after surgery. 5. Examination of the frequency of sedatives and analgesics bolus administration revealed that a greater number of doses were given during daytime (from 7 am. to 7 pm.) than nighttime (from 7 pm. to 7 am.). The difference was significant at Alpha, .05. 6. First factor that most influenced nurses to administer sedatives and analgesics for intubated patients was the evaluation of patient's vital signs (51%). For non- intubated patients, the factors that nurses considered important were the patients' complaints of pain (64%) and evaluations of patients' vital signs (23%). In conclusion, the results of this study indicate that patients in SICU might not receive enough analgesics and sedatives to feel completely free from pain during the post operational period. Future study should be focused on the evaluation of the adequacy of current practice for pain and anxiety control in terms of the SICU patient's response.

본 연구는 노인의 여가력, 가족상태의 융 복합적 접근을 통한 노인의 우울성향을 심층적으로 비교 분석하였다. 본 연구는 65세 이상(평균 73.5세)의 여성노인 20명이 참여하였으며, 대상자의 여가력 분석은 심층면접법으로 총 10문항으로 구성된 구조화된 질문을 통해 여가력을 파악하였으며 가족상태 설문은 가족의 형태, 동거여부 등 총 7문항으로 구성된 설문지를 사용하였다. 우울증 측정은 Geriatric Depression Scrennng; GDS)를 이용하였다. GDS결과에 따라 우울집단과 정상집단을 구분하였으며, 여가력, 가족상태를 통해서 파악한 노인의 우울성향을 비교한 결과는 다음과 같다. 여가력에서 여가의 만족도가 우울만족도에 긍정적 영향을 미쳤으며(F(2,17)=3.989, p<.05), 반면 여가력이 낮거나, 여가동반자가 없는 경우 높은 퇴행적 우울증상을 보였다. 가족상태 중에 본인의 질환 종류에 따라 우울성향에 유의한 영향을 미치는 것으로 분석되었으며(F(3,16)=4.534, p<.05), 그 외 동거유무, 동거인의 건강상태가 우울성향의 평균값의 차이는 높게 나타났다. 결과 노인의 우울 증상은 표현력이 부족하여 우울성향을 쉽게 파악할 수 없으나 오랜 과거력과 주변의 영향을 많이 받는 것으로 나타나 가족의 범주에서 확대하여 지역사회 네트워크와의 관계와 우울에 관한 연구도 필요할 것으로 보인다. 또한, 여가에 있어서도 신체적, 정서적, 사회적 활동의 형태, 활동의 방법, 활동의 정도를 중심으로 한 일회적인 연구가 아니라 종단적 연구를 통해 향후 노인의 여가참여의 질을 높일 수 있는 융복합적 후속연구가 필요할 것으로 사료된다.

Backgrounds and Objectives: A major goat in asthma therapy isto reduce or prevent the inflammatory response associated with bronchial hyperresponsiveness, reversible airway obstruction and airway remodelling. Many studies have shown that eosinophilic infiltration is a prominent feathure in the pathophysiology of asthma. The importance of the Presence of eosinophils in the airways of asthmatics has long been recognized, but the mechanism by which these cells are recruited and retained in the lung are only now being elucidated Production of chemotactic cytokines by bronchial epithelial cells may contribute to the local accumulation of eosinophils in Patients with bronchial asthma. This study was designed to investigate the inhibitory effect of extraction of herbal dicoction, Gamichungsangbohatang(GMCSBHT) on eosinophil chemotactic cytokines. Material and Methods:We used water and 70% ethanol extracts of GMCSBHT and pulmonary epithelial cell lines A549(human type II -like epithelial cells). We estimated cytotoxic effects of GMCSBHT, and estimated the effects of water and 70% ethanol extracts of GMCSBHT on chemokines from prestimulated A549 cells by sandwich ELISA. Results: Chemokines of eotaxin, IL-8 were inhibited by GMCSBHT in dose-dependent manner. And ethanol extract of GMCSBHT has more inhibitory effects on eotaxin, IL-8 than hot water extract. Conculusions: These findings indicate that the supression of the expression of chemokines can be accomplished by GMCSBHT treatment, so GMCSBHT may inhibit the iuflammatory process by eosinophils in asthma.

In current study, we aimed to investigate whether the gentiopicroside (GPS) derived from Gentiana manshurica Kitagawa could block the progression of alcoholic hepatic steatosis to fibrosis induced by chronic ethanol intake. C57BL/6 mice were fed an ethanol-containing Lieber-DeCarli diet for 4 weeks. LX-2 human hepatic stellate cells were treated with GPS 1 h prior to transforming growth factor-β (TGF-β) stimulation, and murine hepatocyte AML12 cells were pretreated by GPS 1 h prior to ethanol treatment. GPS inhibited the expression of type I collagen (collagen I), α-smooth muscle actin (α-SMA) and tissue inhibitor of metal protease 1 in ethanol-fed mouse livers with mild fibrosis. In addition, the imbalanced lipid metabolism induced by chronic ethanol-feeding was ameliorated by GPS pretreatment, characterized by the modulation of lipid accumulation. Consistently, GPS inhibited the expression of collagen I and α-SMA in LX-2 cells stimulated by TGF-β. Inhibition of lipid synthesis and promotion of oxidation by GPS were also confirmed in ethanol-treated AML12 cells. GPS could prevent hepatic steatosis advancing to the inception of a mild fibrosis caused by chronic alcohol exposure, suggesting GPS might be a promising therapy for targeting the early stage of alcoholic liver disease.

목적: 본 연구에서는 서울대학교 어린이병원에서 범저감마글로불린혈증(X-linked agammaglobulinemia [XLA])로 진단된 환자들의 임상적 증상 및 치료에 대해서 보고하고자 하였다. 방법: 14명의 남자 환자가 XLA로 진단되었으며 CD19+ B 세포가 2% 미만이며 Bruton's tyrosine kinase (Btk) 유전자 돌연변이가 있는 경우를 기준으로 하였다. 결과: 모든 XLA 환자에서 반복적인 세균성 감염이 있었고 환자의 20%에서 호중구 감소증이 있었으며 환자 어머니의 75%가 보인자였다. Btk gene study에서는 돌연변이가 다양한 부위에서 나타났으며 특정부위에서 집중적으로 발생하지는 않았다. 면역글로불린 정맥주사 후 반복적인 세균성 감염은 줄어들었으나 합병증으로 기관지 확장증이 14명 중 3명, 지속적인 부비동염은 4명에서 발생하였다. 결론: 4세 이전 세균 감염이 반복되는 경우 XLA와 같은 체액성 면역결핍을 의심하여 글로불린 검사를 하는 것이 조기 진단에 중요하며 Btk 유전자변이 검사를 시행하여 확진한 후 면역글로불린 정맥주사 및 예방적 항생제 등 적절한 치료를 통해 합병증을 줄이고 무 질병 상태를 유지할 수 있다.

The purpose of this study was to review the research on treating depression in Traditional Chinese Medicine(TCM) over the last 5 years to set the foundation for further studies. We searched for and analyzed articles about depression in CNKI(China National Knowledge Infrastructure) from January 2010 to December 2014. The results were as follows : The most frequently used diagnostic criteria was CCMD-3(The Chinese Classification of Mental Disorders-3), and the most used evaluation criteria was HAMD(Hamilton Depression Rating Scale). Prescription of decoction of medical herbs was most frequently used as a therapeutic method. Acupuncture, traditional Chinese psychotherapy, and music therapy were also used for some studies. The most frequent TCM Syndrome Differentiation Type was stagnation of liver-QI. For decoction of Chinese herbs, Soyo-san(Xiaoyao-san) and Sihosogan-san(Chaihushugan-san) were most often prescribed, and Bupleuri Radix, Paeoniae Radix Alba, Curcumae Radix, Poria cocos wolf, Angelicae Gigantis Radix, Atractylodis Rhizoma Alba were mainly used for medical herbs. BaekHoi(GV20) and Yindang(Ex-HN3) were often used as acupuncture sites. Post-Stroke Depression was the most common case of intercurrent or secondary depression. According to the Jadad Quality Assessment Scale, the quality of the reports was not high as most of the reports had a score of 3 or below. Most systematic reviews on depression were conducted by Chinese researchers. The problem with Clinical research on depression, according to those reviews, was that there were no standardized criteria for the diagnosis and treatment and the trials were usually not randomized nor controlled. We found out there are various clinical methods for treating depression in TCM, and hope that this research could provide the preliminary data for designing and conducting clinical trials for depression.
