Genome sequencing of the pig is being accelerated because of its importance as an evolutionary and biomedical model animal as well as a major livestock animal. However, information on expressed porcine genes is insufficient to allow annotation and use of the genomic information. A series of expressed sequence tags of 5' ends of five full-length enriched cDNA libraries (SUSFLECKs) were functionally characterized. SUSFLECKs were constructed from porcine abdominal fat, induced fat cells, loin muscle, liver, and pituitary gland, and were composed of non-normalized and normalized libraries. A total of 55,658 ESTs that were sequenced once from the 5′ ends of clones were produced and assembled into 17,684 unique sequences with 7,736 contigs and 9,948 singletons. In Gene Ontology analysis, two significant biological process leaf nodes were found: gluconeogenesis and translation elongation. In functional domain analysis based on the Pfam database, the beta transducin repeat domain of WD40 protein was the most frequently occurring domain. Twelve genes, including SLC25A6, EEF1G, EEF1A1, COX1, ACTA1, SLA, and ANXA2, were significantly more abundant in fat tissues than in loin muscle, liver, and pituitary gland in the SUSFLECKs. These characteristics of SUSFLECKs determined by EST analysis can provide important insight to discover the functional pathways in gene networks and to expand our understanding of energy metabolism in the pig.

Purpose: Various postoperative adjuvant chemotherapy regimens have been proposed for the patients with advanced gastric cancer. The majority of clinical trials have shown no significant difference in the survival benefit. The aim of this study was to compare the survival rates of postoperative adjuvant chemotherapies used in stage III gastric cancer patients who received curative gastrectomy. Materials and Methods: Between 1990 and 1999, a survival analysis was performed in 260 patients who received curative gastric resection and postoperative adjuvant chemotherapy. The patients were divided into four groups according to the chemotherapeutic regimens received. The groups were: the F group: furtulon alone, FM group: furtulon and mitomycin, FAM group: 5-FU, adriamycin and mitomycin, FLEP group: 5-FU, leucovorin, etoposide and cisplatin. The survival rates were analyzed using the Kaplan-Meier method and the Cox proportional hazards model. Results: There were no differences among the groups of patients with regard to tumor characteristics except for lymph node metastasis and the ratio of metastasis to lymph nodes. In the FLEP group, the ratio of metastasis to lymph nodes was higher than in the other groups. The five and ten year survival rates of F, FM, FAM and FLEP were 51.9%, 28.9%, 59.5%, 49.8%, 66.1%, 57.4% and 30.0%, 27.5%, respectively. The univariate analysis showed that age, Borrmann type, lymph node metastasis, ratio of metastasis to lymph nodes, postoperative adjuvant chemotherapy and recurrence were significant factors for survival. For the multivariate analysis, recurrence, age, Borrmann type, ratio of lymph node metastasis and lymph node dissection were independent prognostic factors; however, the postoperative adjuvant chemotherapy was not an independent prognostic factor. Conclusion: The FAM regimen was the most beneficial postoperative adjuvant chemotherapy for improved survival rates; the FM regimen was the second and the FLEP regimen was the last. In order to determine the effectiveness of postoperative adjuvant chemotherapy in stage III gastric cancer, well designed prospective studies including a surgery only group will be needed.

Background: Prior studies showed a relationship between serum albumin and the albumin to globulin ratio with different types of cancer. We aimed to evaluate the predictive value of the albumin-globulin ratio (AGR) for survival of patients with lung adenocarcinoma. Materials and Methods: This retrospective study included 240 lung adenocarcinoma patients. Biochemical parameters before chemotherapy were collected and survival status was obtained from the hospital registry. The AGR was calculated using the equation AGR=albumin/(total protein-albumin) and ranked from lowest to highest, the total number of patients being divided into three equal tertiles according to the AGR values. Furthermore, AGR was divided into two groups (low and high tertiles) for ROC curve analysis. Cox model analysis was used to evaluate the prognostic value of AGR and AGR tertiles. Results: The mean survival time for each tertile was: for the $1^{st}$ 9.8 months (95%CI:7.765-11.848), $2^{nd}$ 15.4 months (95%CI:12.685-18.186), and $3^{rd}$ 19.9 months (95%CI:16.495-23.455) (p<0.001). Kaplan-Meier curves showed significantly higher survival rates with the third and high tertiles of AGR in comparison with the first and low tertiles, respectively. At multivariate analysis low levels of albumin and AGR, low tertile of AGR and high performance status remained an independent predictors of mortality. Conclusions: Low AGR was a significant predictor of long-term mortality in patients with lung adenocarcinoma. Serum albumin measurement and calculation of AGR are easily accessible and cheap to use for predicting mortality in patients with lung adenocarcinoma.

Background: The tumor-stroma ratio (TSR) represents the percentage of neoplastic cell components compared to the combined area of neoplastic cells and the surrounding tumor-induced stroma. A low TSR (predomination of stromal component) has been demonstrated to be an independent adverse prognostic factor in cancers of several organs. In cervical carcinoma patients, TSR has been evaluated in only one previous study with different histological types. The present study aimed to assess the prognostic value of TSR in early stage cervical cancer patients with adenocarcinoma histology only. Materials and Methods: Histological slides of patients with early stage (IB-IIA) cervical adenocarcinoma who underwent surgical treatment between January 2003 and December 2011 were reviewed. Patients who had received preoperative chemotherapy were excluded. TSR was categorized as low (<50%) and high (${\geq}50%$). Correlations between TSR and clinicopathological variables were evaluated. Prognostic values of TSR and other variables were estimated using Cox's regression. Results: Of 131 patients; 38 (29.0%) had low TSR and 93 (71.0%) had high TSR. The patients with low TSR had significantly higher proportions of deep cervical stromal invasion (outer third of wall, p=0.011; residual stroma less than 3 mm, p=0.008) and parametrial involvement (p=0.026). Compared to the patients with high TSR, those with low TSR tended to have lower 5-year disease-free survival rate (83.8% versus 88.9%) and overall survival rate (85.6% versus 90.3%), although the differences were not statistically significant. Low TSR was significantly associated with decreased overall survival in univariate analysis (HR 2.7; 95% CI 1.0-7.0; p=0.041), but not in multivariate analysis. TSR was not significantly associated with decreased disease-free survival. Conclusions: Low TSR is associated with decreased overall survival in patients with early stage cervical adenocarcinoma treated by surgery. However, it was not found to be an independent prognostic predictor in this study.

To determine the relationship between comorbidity and outcome after radical cystectomy in Chinese patients by using the Adult Comorbidity Evaluation (ACE)-27 index. Two-hundred-and-forty-six patients treated with radical cystectomy at the Second Xiangya Hospital of Central South University, Hunan Province, China between 2000 and 2010 were retrospectively analyzed. Medical records were reviewed for age, gender, delayed time of radical cystectomy, urinary diversion type, pelvic lymphadenectomy status, TNM stage, and pathological grade. Comorbidity information was assessed by the ACE-27 index. The outcome measurement was overall survival. Univariate and multivariate Cox proportional hazards regression analyses were used to determine the association between comorbidity and outcome. The study population consisted of 215 (87.40%) males and 31 (12.60%) females with a mean age of $62{\pm}11$ years. Median duration of follow-up was $47{\pm}31$ months. A total of 151 (61.38%) patents died during follow-up. Of those, 118 (47.97%) had at least one comorbidity. According to the ACE-27 scores, 128 (52.03%) patients had no comorbidity, 79 (32.11%) had mild, 33 (13.41%) had moderate, and 6 (2.45%) had severe comorbidities. Multivariate analysis indicated that moderate (p=0.002) and severe (p<0.001) comorbidity was significantly associated with decreased overall survival. In addition, age ${\geq}70$ years (p=0.002), delayed time of radical cystectomy >12 weeks (p=0.044), pelvic lymphadenectomy status (p=0.014), and TNM stage >T3 (p<0.001) were determined to be independent risk factors of overall survival. Increasing severity of comorbidity statistically correlated with decreased overall survival after radical cystectomy.

Objective: To analyze the efficacy and survival associated factors of gefitinib combined with cisplatin and gemcitabine for advanced non-small cell lung cancer. Materials and Methods: A total of 57 patients with advanced non-small cell lung cancer (NSCLC), who received platinum-based chemotherapy regimens for more than 1 cycle, were treated with gefitinib combined with cisplatin and gemcitabine until disease progression. Efficacy, survival time and adverse reactions were observed. The Kaplan-Meier method was adopted for analysis of survival and Cox regression for associated influencing factors. Results: The patients were followed up until October 31, 2013, and the median follow-up time was 19 months. Of 57 patients, there were 4 (7.0%) with complete remission (CR), 8 (14.0%) with partial remission, 31 (54.4%) with stable disease, and 14 (24.6%) with disease progression. The remission rate was 21.1% and the disease control rate was 75.4%. The median progression-free survival (PFS) time and the median overall survival time were 10 months and 15.2 months. The one-year, two-year and three-year survival rates were 47.4%, 23.3% and 10.0%. Gender and pathological types were the independent risk factors influencing PFS time (P=0.028, P=0.009). Tumor pathological type and early efficacy were independent factors for the prognosis (P=0.018, P=0.000). Adverse reactions were mostly rashes of I~II degree and diarrhea and slightly increasing level of aminopherase. The skin adverse event incidence of III degree or above was 1.8% (1/57) and brain metastasis was foudn in 31.6% (18/57). Conclusions: Gefitinib combined with cisplatin andgemcitabine, is effective for patients with IIIb~IV NSCLC who received multiple cycles of chemotherapy.

Background: We aimed to evaluate prognostic factors and response rates to various treatment approaches to patients with synovial sarcoma in an advanced setting. Materials and Methods: We retrospectively reviewed the medical records of 55 patients (18 pts; 32.7% women) diagnosed with synovial sarcomas. Twenty had metastatic disease at the time of diagnosis while the remainder of the study group consisted of patients who developed metastatic or inoperable locally advanced disease during follow up. Results: The median follow up time was 15 months (range: 1-53). Regarding outcomes for the 55 patients, 3 and 5 year overall survival rates were 26% and 14%, respectively. In univariate analyses among demographic factors female gender was associated with a better outcome (p=0.030). Patients with early progressing disease (<2 years) had a worse prognosis when compared to patient group with late relapse, but this difference did not reach statistical significance (p=0.056). According to multivariate Cox regression analysis patients who had undergone metastasectomy had a significant survival advantage (p=0.044). The overall response rate to different salvage chemotherapy regimens given as second line treatment was around 42.9-53.9% for all regimes. There were no statistically significant differences between chemotherapy regimens given in either second or third line settings in terms of overall survival. Conclusions: We observed no major differences in terms of response rate and survival between different salvage chemotherapy regimens. Although metastatic disease still carries a poor prognosis, metastasectomy was found to be associated with improved survival.

Objectives : Illicium verum Hook. f. has been known to possess antimicrobial, antioxidant, antifungal, anti-inflammatory, insecticidal, analgesic, sedative, convulsive activities, it has been rarely conducted to evaluate the immuno-biological activity. The present study was examined to evaluate the anti-inflammatory effects of the Illicium verum Hook. f. water extracts (IVE) in vivo and in vitro. Methods : Cell viability was measured by MTT assay. The relative levels of NO were measured with Griess reagent. iNOS, COX-2, $NF-{\kappa}B$ and target proteins were detected by immunoblot analysis, and levels of cytokines were analyzed by ELISA kit. Anti-edema effect was determined in the carrageenan (CA)-induced paw edema model in rats. Results : All dosages of IVE used in MTT assay had no significant cytotoxicity. The increases of NO production and iNOS expression were detected in LPS-treated cells compared with control. However, these increases were attenuated by treatment with IVE. Also, IVE reduced the elevated production of $TNF-{\alpha}$, $IL-1{\beta}$ and IL-6 by LPS. IVE inhibited the $p-I{\kappa}B$ and translocation of $NF-{\kappa}B$ to nuclear. Furthermore, IVE significantly inhibited the increases of hind paw swelling, skin thicknesses and inflammatory cell infiltrations induced by CA injection. Therefore, IVE will be favorably inhibited the acute edematous inflammations. Conclusion : These results provide evidences that anti-inflammatory effect of IVE is partly due to the reduction of some inflammatory mediators by suppression of $NF-{\kappa}B$ pathway.

From May, 1979 to October,1987, 38 patients with endometrial carcinoma were treated with radiotherapy at Seoul National University Hospital. Of these, 32 patients received radiotherapy Postoperatively, one received radiotherapy preoperatively, and five received radiotherapy only. Relative frequencies of obesity, nulliparity, late menopause, diabetes mellitus, and hypertension were all higher than those reported in normal women in Korea, and those of obesity, diabetes mellitus, and nulliparity were significantly high. The overall actuarial five-year survival rate was $75.6\%$. The overall actuarial five year survival rates of stage I (22 cases), stage II (six cases), and stage III (10 cases) were $90.0\%,\;80.0\%,\;and\;44.4\%$, respectively, and were significantly different from each other. Among various factors, stage only proved to be prognostic by multivariate analysis. There were two local failures, three local failures combined with distant metastasis, and three distant metastasis. Stages I and II could be adequately controlled by local modalities without severe complications, stage III endometrial carcinoma might need more aggressive treatment for better survival.

Atopic dermatitis(AD) is a chronic inflammatory skin disease. AD has increased gradually, many people are tortured with AD. Chunggi-san(CG) and Samhwangseze-gamibang(SG) has been used for many kinds of skin disease in the Oriental medicine. But reports about the effect of CG and SG are insufficient. So, author investigated the effect of CG and SG on NC/Nga atopic mice. Major findings are summarized as follows: The clinical skin severity scores of experimental group in 13 and 16 week were decreased by 42% and 50% compared to the control group. Serum IgE, IL-4, IL-5, IL-6, IgM, IgGI levels of experimental group were significantly decreased compared to the control group. Serum $IFN-\nu$ was significantly increased in the experimental group compared to the control group. mRNA expression levels of IL-4, IL-5, and CCR3 in the skin tissues of experimental group were significantly decreased, and expression level of IL-6 in the skin tissues of experimental group was significantly decreased compared to the control group. $IFN-\nu$ mRNA expression levels was increased compared to the control group. According to biopsy reports of the ear and skin tissues showed that the tissue damage, experimental group were highly reduced compared to the control group. Judging from that $IL-1{\beta}$, $TNF-{\alpha}$, IL-6 express of gene, the effects of inflammatory cytokines revelation were significantly decreased compared to the control group. Depending on the density of CG, inflammatory RAW 264.7 in the serum of CG were significantly inhibited compared to the control serum that leaded a COX-2 activity model.
