Aim To discuss the influence of endosome/ lysosome transport proteins SNX10 on macrophage, providing new potential targets for the treatment of variety of related immune diseases . Methods The genotype of mice was identified by PCR. The role of SNX10 in phagocytosis of bacterial components and sterilization by macrophages were assessed. The levels of TNF-α、IL-12 / 23 p40 and IL-6 were measured by q-PCR and ELISA assay. Finally, the NF-κB signaling pathway was evaluated by Western blot and immuno-fluorescence staining. Results Ex vivo experiments showed that SNX10 knockout could enhance bactericid-al ability and inhibit the expression and production of TNF-α, IL-12 / 23 p40 and IL-6 of macrophages.These effects might attribute to the inhibition of NF-κB signaling pathway activation. Conclusion SNX10 knockout could enhance bactericidal ability and inhibit the inflammatory response of macrophages, and its mechanism may be achieved through the NF-κB signa-ling pathway.

OBJECTIVES: Health is closely related to an individual's assessment of their quality of life and their subjective level of happiness. The aim of this study was to investigate the association between happiness index and self-rated health by utilizing a community health survey in Korea. METHODS: The study participants were 17,937 people living in Gyeongsangnam-do, Korea, who completed a community health survey in 2014. The non-subjective variables included in the statistical analysis were sex, age, region, education, income, and economic activity. The subjective awareness variables included self-rated health, self-rated oral health, chewing difficulty, pronunciation difficulty, and happiness index. Statistical analysis of the data was done using the SPSS 21.0 program. RESULTS: Evaluation of the subjective awareness levels revealed that the respondents that were better educated, whose income levels were higher, and those who engaged in an economic activity found themselves to be in better physical health and oral health. In contrast, the respondents that were female, older, and with residence in the counties reported a higher incidence of chewing difficulty. There was a positive correlation between happiness index and subjective awareness level, and a negative correlation between chewing difficulty and pronunciation difficulty. Happiness index was influenced the most by subjective health levels, followed by income, age, pronunciation difficulty, subjective oral health, chewing difficulty, academic credential, region, and sex. CONCLUSIONS: Therefore, in order to improve the happiness index of community residents, regular health checkups and systematic oral health education should be prepared in order to improve awareness of subjective health and reduce discomfort in the oral cavity, and efforts should be made to reduce the gap between regions.

We expirenced multiple hepatocellular adenomatosis, which was proved by pathology, in 38 years old man who had no prior history of predisposing factors. The radiologic findings were different by the size of tumor mass and intratumoral hemorrhage. Ultrasound demonstrated inhomogeneous hyperechoic large mass in segment 5 of right lobe and hyperechoic or isoechoic multiple small nodules in right lobe. Computed tomography demonstrated low density mass without contrast enhacement. Central high density is noted in hemorrhagic portion. Magnetic resonance T1-weighted image demonstrated high signal intensity in mass and hemorrhagic portion. T2-weighted image demonstrated slightly high signal intensity in mass portion, high signal intensity in hemorrhagic portionand double-layered peripheral rim. Gradient echo image well demonstrated inhomogenesity of mass.

Objective To evaluate the risk of plague occurrence via surveying and analyzing indoor rat density and flea index in natural villages having previous plague experience. Methods During August to September 2007, 30 natural villages experiencing previous plague were selected based on the surveillance data, and then all households were coded with numbers and 20 households in each village were randomly selected via computer. Cages and sticky papers were set in 600 selected households to capture rats and fleas. Rat density, flea prevalence, flea index and median were estimated. Results One hundred thirty-three Rattus flavipectus and 33 Suncus murinus were caught and averaged rat density was 2.8 rats per one hundred cage. nights (166/6000), the median was 5 rats each village. One hundred and one mice infected fleas, flea prevalence on rats was 60.8% (101/166), 296 Xenopsylla cheopis and 48 Leptopsylla segnis were collected. Rat flea index was 2.1 fleas per rat (344/166). A total of 315 dissociated flea was caught, average dissociated flea index was 0.026 fleas per sticky paper (315/11888). The median was 5.5 dissociated fleas per village. Of dissociated fleas, Ctenocephalides felis felis (205) and Xenopsylla cheopis (103) accounted for 97.8% (308/315). The proportion for species of the rat flea and the dissociated flea was different(Fisher test: P < 0.01). The rat flea was significantly associated with the rat density(r = 0.68, P < 0.01), but the dissociated flea was significantly associated with neither the rat density(r = -yield than fried wheat batter(χ2 = 5.59, P < 0.05). Conclusions In these villages having previous plague experience of Lianghe County, Rattusflavipectus was dominant species of indoor rats, Xenopsylla cheopis and Ctenocephalides felis felis were dominant species of rat flea and dissociated flea, respectively. Mengsong, Bangdu, and Tangjiatun village had potential risk of plague emergence.

To investigate the effects of gambognic acid (GA) on TRAIL-induced apoptosis of cancer cells, human colon HT-29 cancer cells were treated with GA to promote apoptosis. Inhibition of the cell proliferation was measured with MTT assay and cell apoptosis was detected with formation of DNA ladders in agarose gel electrophoresis, and activation of caspase activity. The content of cytosolic reactive oxygen species (ROS) was measured with flow cytometry. The activities of Caspase-3, -8, -9 were detected using spectrophotometric assay. The levels of c-FLIP, CHOP, DR4 and DR5 in cells were tested by Western blot. Combination of GA (1 µg · mL(-1)) and TRAIL (40 ng · mL(-1)) significantly reduced proliferation and increased apoptosis of HT-29 cells over those induced by each agent alone. Percentage of apoptotic cells was increased to 45.5%. GA markedly enhanced the intracellular ROS generation. Expression of CHOP, DR4 and DR5 was up-regulated to 7.38, 5.41, and 4.85 times of the control group, respectively. GA promoted activation of Caspase-3, -8, and -9 by TRAIL (P<0.05). Furthermore, the expression of anti-apoptotic protein c-FLIP was down-regulated to 0.22 ± 0.08 times of the control group. In conclusion, GA sensitizes HT-29 cells to TRAIL-induced apoptosis by promoting ROS-activated ERS pathways, up-regulating of DR4 and DR5, and inhibiting c-FLIP expression.

PURPOSE: Survival outcome of locally advanced pancreatic cancer has been poor and little is known about prognostic factors of the disease, especially in locally advanced cases treated with concurrent chemoradiation. This study was to analyze overall survival and prognostic factors of patients treated with concurrent chemoradiotherapy (CCRT) in locally advanced pancreatic cancer. MATERIALS AND METHODS: Medical records of 34 patients diagnosed with unresectable pancreatic cancer and treated with definitive CCRT, from December 2003 to December 2012, were reviewed. Median prescribed radiation dose was 50.4 Gy (range, 41.4 to 55.8 Gy), once daily, five times per week, 1.8 to 3 Gy per fraction. RESULTS: With a mean follow-up of 10 months (range, 0 to 49 months), median overall survival was 9 months. The 1- and 2-year survival rates were 40% and 10%, respectively. Median and mean time to progression were 5 and 7 months, respectively. Prognostic parameters related to overall survival were post-CCRT CA19-9 (p = 0.02), the Eastern Cooperative Oncology Group (ECOG) status (p < 0.01), and radiation dose (p = 0.04) according to univariate analysis. In multivariate analysis, post-CCRT CA19-9 value below 180 U/mL and ECOG status 0 or 1 were statistically significant independent prognostic factors associated with improved overall survival (p < 0.01 and p = 0.02, respectively). CONCLUSION: Overall treatment results in locally advanced pancreatic cancer are relatively poor and few improvements have been accomplished in the past decades. Post-treatment CA19-9 below 180 U/mL and ECOG performance status 0 and 1 were significantly associated with an improved overall survival.

Journal of the Korean Ophthalmological Society 2011;52(1):14-22
PURPOSE: To investigate the predisposing factors, clinical manifestations, treatment results and risk factors for treatment failure in Staphylococcus epidermidis keratitis. METHODS: Sixty-one eyes of 61 patients who were diagnosed with Staphylococcus epidermidis keratitis were included in the present study. The past history, location and size of ulceration, hypopyon, treatment results, and antibiotic susceptibility were reviewed retrospectively. A logistic regression analysis was performed to identify the main prognostic risk factors for treatment failure. RESULTS: Twenty-six eyes (42.6%) had previous histories of corneal traumas. Polymicrobial infections were observed in 31 cases (50.8%), including 11 cases (35.5%) combined with the Fusarium species. Twenty-five eyes (41.0%) had lesions located at the corneal center. The average size of ulceration was 7.3 +/- 7.2 mm2. Thirteen eyes (21.3%) with lesions that progressed or occurred in the corneal perforation underwent evisceration, penetrating keratoplasty or scleral graft. Risk factors for treatment failure were a history of previous keratitis (P = 0.003) and an ulcer exceeding 5.0 mm2 in size (P = 0.018). CONCLUSIONS: Staphylococcus epidermidis keratitis usually has a good prognosis, although a history of previous keratitis and a large ulcer size are risk factors for treatment failure.

The authors diagnosed a 54-year-old male as central mucoepidermoid carcinoma after undegoing clinical, radiologica l and histopathological examinations. The charateristics were as followed : 1. Clinically, the patient complained of the painless unilateral swelling of the left mandibular molar region and had a pus discharge through the fistula. Painful nodule was palpated on the scalp of the left frontal area and it was regarde d as a metastatic lesion. 2. Plain radiographs showed the ill-defined permeative radiolucent lesion. The osteolytic lesions were also detected in the cranial bone, number 9 and 11 ribs, scapula, and vertebral bodies. 3. The mandibular CT and PNS MRI showed the swelling of the left mandible and the enlargement of the several lymph node s of 1.5 cm in size. 4. Histopathologically, many solid epidermoid type cells were mixed with mucus-secreting cells and they were arranged i n duct-like structure. Most of them were epidermoid type, which indicates a high grade tumor. Mucins could be found in mucicarmine staining.
