Abstract
AIM A psychological behaviour management programme with information and communications technology was developed that includes symbolic modelling, tell-show-do, positive reinforcement and distraction, and provides real-time treatment information. We hypothesised that the programme would help patients feel less stressed and show less uncooperative behaviours and subjective pain. MATERIALS AND METHODS Forty-eight paediatric patients were recruited from May 2016 to January 2017, and randomly divided into a control group and an experimental group. In the control, patients watched cartoon animations during the first and second treatments. The experimental group watched cartoon animations during the first treatment, and they used the programme during the second treatment. To measure stress, uncooperative behaviour and subjective pain, we recorded the heart rate, Procedure Behaviour Checklist (PBCL) and Wong and Baker's Faces Pain Rating Scale (FPRS). RESULTS The experimental group resulted in a significantly lower mean heart rate, uncooperative behaviour and subjective pain in the second treatment than did the control group (p<0.001). The differences in heart rate and uncooperative behaviour between the treatments were also significantly greater in the experimental group than in the control group (p<0.001). CONCLUSION The programme was effective in relieving fear and anxiety as well as learning cooperative behaviour.

Abstract
BACKGROUND Frequent wheezing in original asthma predictive index (API) was defined by parental report of recurrent wheezing within 1 year during the first 3 years of life. The nature of frequent wheezing in children, particularly aged over 3 years, has not been studied. We aimed to assess the frequency and interval of wheezing to define frequent wheezing in ascertaining asthma for children using medical records. METHODS Among children who participated in a previous study (n = 427), all wheezing episodes documented in medical records were collected for children who had ≥2 wheezing episodes PLUS met one major criterion or two minor criteria of API. We compared the distribution of known risk factors for asthma between subjects having two consecutive wheezing episodes with shorter interval (≤1 year) compared to those with longer interval (1 to 3 years). RESULTS A total of 62 children met API at median age of 2.3 years. During follow-up period (median age: 11.3 years), a total of 198 wheezing episodes were observed. 81% of wheezing intervals were within 3 years from the earlier wheezing episode, including 60% within 1 year. Children who met API based on 1-year interval (n = 40) vs 1- to 3-year interval (n = 13) appeared to be similar in regard to the known risk factors for asthma. CONCLUSIONS Our exploratory study finding suggests that children who had frequent wheezing episodes with longer interval (<3 years) need to be considered to be determined as asthma cases when API is applied to retrospective medical records. Prospective studies with a larger sample size need to replicate this finding.

Abstract
Pulp capping, or placing dental materials directly onto the vital pulp tissues of affected teeth, is a dental procedure that aims to regenerate reparative dentin. Several pulp capping materials are clinically being used, and calcium ion (Ca(2+)) released from these materials is known to mediate reparative dentin formation. ORAI1 is an essential pore subunit of store-operated Ca(2+) entry (SOCE), which is a major Ca(2+) influx pathway in most nonexcitable cells. Here, we evaluated the role of ORAI1 in mediating the odontogenic differentiation and mineralization of dental pulp stem cells (DPSCs). During the odontogenic differentiation of DPSCs, the expression of ORAI1 increased in a time-dependent manner. DPSCs knocked down with ORAI1 shRNA (DPSC/ORAI1sh) or overexpressed with dominant negative mutant ORAI1(E106Q) (DPSC/E106Q) exhibited the inhibition of Ca(2+) influx and suppression of odontogenic differentiation and mineralization as demonstrated by alkaline phosphatase (ALP) activity/staining as well as alizarin red S staining when compared with DPSCs of their respective control groups (DPSC/CTLsh and DPSC/CTL). The gene expression for odontogenic differentiation markers such as osteocalcin, bone sialoprotein, and dentin matrix protein 1 (DMP1) was also suppressed. When DPSC/CTL or DPSC/E106Q cells were subcutaneously transplanted into nude mice, DPSC/CTL cells induced mineralized tissue formation with significant increases in ALP and DMP1 staining in vivo, whereas DPSC/E106Q cells did not. Collectively, our data showed that ORAI1 plays critical roles in the odontogenic differentiation and mineralization of DPSCs by regulating Ca(2+) influx and that ORAI1 may be a therapeutic target to enhance reparative dentin formation.

Abstract
PURPOSE The study investigated the effect of intravitreally administered tanibirumab, a fully human monoclonal antibody against vascular endothelial growth factor receptor 2, in a rat model of laser-induced choroidal neovascularization (CNV). METHODS CNV was induced by laser photocoagulation on day 0 in the eyes of Brown Norway rats. Intravitreal injection of tanibirumab or phosphate-buffered saline (PBS) was done on day 0 (prevention arm) or day 7 (treatment arm). Seven days after injection, the eyes were enucleated and retinal pigment epithelium-choroid-sclera flat mounts were prepared. Areas of CNV were determined in the flat mounts using tetramethylrhodamine isothiocyanate Bandeiraea simplicifolia (BS) isolectin labeling and intravenously administered fluorescein isothiocyanate-dextran and quantified using an image analysis program. RESULTS In the prevention arm, the mean area of CNV measured by BS isolectin labeling was reduced by 28.2% and 53.9% in tanibirumab-treated eyes (20 and 60 μg, respectively) compared with PBS-treated control eyes on day 7 (P=0.038 and P<0.001, respectively). In the treatment arm, the mean area of CNV measured by BS isolectin labeling was reduced by 28.7% and 46.0% in tanibirumab-treated eyes (20 and 60 μg, respectively) compared with PBS-treated control eyes on day 14 (P=0.048 and P<0.001, respectively). CONCLUSIONS Intravitreally administered tanibirumab partially suppressed the formation of new CNV and partially regressed preformed laser-induced CNV in the rat model. Tanibirumab may be a feasible treatment for CNV associated with age-related macular degeneration or other causes.

Abstract
Singleton-Merten syndrome (SMS) is an autosomal-dominant multi-system disorder characterized by dental dysplasia, aortic calcification, skeletal abnormalities, glaucoma, psoriasis, and other conditions. Despite an apparent autosomal-dominant pattern of inheritance, the genetic background of SMS and information about its phenotypic heterogeneity remain unknown. Recently, we found a family affected by glaucoma, aortic calcification, and skeletal abnormalities. Unlike subjects with classic SMS, affected individuals showed normal dentition, suggesting atypical SMS. To identify genetic causes of the disease, we performed exome sequencing in this family and identified a variant (c.1118A>C [p.Glu373Ala]) of DDX58, whose protein product is also known as RIG-I. Further analysis of DDX58 in 100 individuals with congenital glaucoma identified another variant (c.803G>T [p.Cys268Phe]) in a family who harbored neither dental anomalies nor aortic calcification but who suffered from glaucoma and skeletal abnormalities. Cys268 and Glu373 residues of DDX58 belong to ATP-binding motifs I and II, respectively, and these residues are predicted to be located closer to the ADP and RNA molecules than other nonpathogenic missense variants by protein structure analysis. Functional assays revealed that DDX58 alterations confer constitutive activation and thus lead to increased interferon (IFN) activity and IFN-stimulated gene expression. In addition, when we transduced primary human trabecular meshwork cells with c.803G>T (p.Cys268Phe) and c.1118A>C (p.Glu373Ala) mutants, cytopathic effects and a significant decrease in cell number were observed. Taken together, our results demonstrate that DDX58 mutations cause atypical SMS manifesting with variable expression of glaucoma, aortic calcification, and skeletal abnormalities without dental anomalies.

Abstract
PURPOSE To assess whether the expression of heat shock protein 72 (Hsp72) protects rat retinal ganglion cells (RGC-5) from apoptotic cell death. METHODS Hsp72 expression in RGC-5 cells transduced with replication-deficient recombinant adenovirus was analyzed by Western blot analysis and immunofluorescence. The effect of Hsp72 expression on etoposide-induced apoptotic cell death was examined by microscopic analysis and confirmed by cell proliferation assay. RESULTS Western blot analysis and immunofluorescence clearly showed adenovirus-mediated Hsp72 expression in RGC-5 cells. Treatment with etoposide resulted in the death of a proportion of the cells by apoptosis. However, this apoptotic cell death was significantly reduced in cells expressing Hsp72, with the reduction in cell death correlating to the level of Hsp72 expression. CONCLUSIONS Over-expression of Hsp72 alone is sufficient to rescue neuronal cells from apoptotic cell death, suggesting that fine-tuning its expression may be an effective neuroprotective approach in retinal degenerative disease.

Abstract
INTRODUCTION We investigated the distribution of myosin heavy chain (MyHC) isoforms along the length of the global and orbital layers of human extraocular muscles (EOMs). METHODS Whole muscle tissue extracts of human EOMs were cross-sectioned consecutively and separated into orbital and global layers. The extracts from these layers were subjected to electrophoretic analysis, followed by quantification with scanning densitometry. RESULTS MyHC isoforms displayed different distributions along the lengths of EOMs. In the orbital and global layers of all EOMs except for the superior oblique muscle, MyHCeom was enriched in the central regions. MyHCIIa and MyHCI were most abundant in the proximal and distal ends. CONCLUSIONS A variation in MyHC isoform expression was apparent along the lengths of human EOMs. These results provide a basis for understanding the molecular mechanisms underlying the functional diversity of EOMs.

Abstract
SUMMARY
Objective
The purpose of this study was to evaluate the effects of different desensitizing agents on the prevention of root caries when applied to root surfaces.
Materials and Methods
Thirty human roots were sectioned into quarters with a 3 × 4 mm window. A desensitizer (VX, Clinpro™ XT Varnish; SP, Seal & Protect®; or PB, Clearfil™ Protect Bond) was applied to three of the quarters in each window. Teeth were stored separately in water for one day, 30 days, or 60 days. The remaining quarter, without the application of desensitizer, served as a control. After storage in water, all specimens were subjected to pH cycling. Scanning electron microscopy was used to observe the demineralization bands created on the subsurface layer. The weight percentages of fluorine (F), silica, and calcium (Ca) were determined using electron probe microanalysis to quantify the elemental distributions in the root dentin. The concentrations of F released during a pH cycling were measured.
Results
For the control group, the average lesion depth was 18.92 ± 5.42 μm, and the average Ca loss was 15.66% ± 6.80% in the superficial layer and 30.44% ± 9.61% in the subsurface layer. No Ca loss occurred in the desensitizer-treated groups. All desensitizing agents remained intact for at least 60 days. F levels were increased in the hybrid layer but not in the subhybrid area. Outward release of F diminished with time.
Conclusion
The F-containing resin-based desensitizers protected exposed root surfaces from demineralization. F liberated from the desensitizers was detected only at minimal levels.

Abstract
Several animal models of Behçet's disease (BD) have been proposed according to putative etiology. Among these models, the herpes simplex virus (HSV)-induced model produced the most similar disease attributes observe in patients. Inoculation of HSV type 1 to the scratched earlobe of mice produced the appropriate symptoms, including oral, genital, and skin ulcers, eye lesions, arthritis, and intestinal involvement. This HSV-induced BD model is the only continuously used model, to which various therapeutic modalities have been applied.

Abstract
BACKGROUND Public reporting (PR) has been gaining more weight as a mechanism for patient steerage. According to the theory of PR, patients use information about the quality of health care providers before making decisions and selecting health-care providers. This paper contributes further knowledge on the effectiveness of PR and identifies critical success factors. These should be taken into account when implementing PR in the German health care system. METHODOLOGY The peer-reviewed English, Spanish, and German language literature was searched in the following five databases: The Cochrane Library, Medline (via PubMed), ISI Web of Knowledge, EconLit, and PsycINFO (since 2005). In addition, reference lists of the included studies and reviews were screened in order to identify previously published studies. RESULTS In total, 21 studies were identified regarding the impact of 12 different PR instruments on patient steerage. An impact could be demonstrated in 9 studies, 7 studies showed mixed results, while 5 studies could not show any effect on patient steerage. 20 studies were carried out in the US environment, 1 study in Germany. The most researched instrument is the New York State Cardiac Surgery Reporting System (N=8). CONCLUSION PR can be effective in steering patients when seeking a health-care provider, especially for elective procedures. To be successful, information provided must be reliable, easily understandable, should further represent real news, and be disseminated widely. Besides this, it has to be applicable and modifiable according to individual preferences.

Abstract
Background/aim To determine if overexpression of the glaucoma gene MYOC is involved in the development of open-angle glaucoma (OAG) and if its promoter variants are associated with glaucoma in the Korean population. Methods Human trabecular meshwork cells were cultured in the presence of ophthalmic steroids such as fluorometholone, fluorometholone acetate, dexamethasone, prednisolone acetate and rimexolone. The cells were cultured at a hydrostatic pressure of 32 mm Hg above atmospheric pressure and induction of MYOC was evaluated by northern blot analysis. Genomic DNA was extracted from blood samples obtained from 74 normal controls and 168 unrelated Korean patients with OAG, including primary OAG, normal tension glaucoma and steroid-induced glaucoma. A 461 base pair (bp) DNA fragment of the MYOC promoter region was amplified using PCR and its genotype was analysed by directly sequencing the product. Results The potencies of steroid eye drops in MYOC induction in vitro was the same regardless of their potential for elevating intraocular pressure in vivo. Hydrostatic pressure had no effect on MYOC induction. A dinucleotide repeat polymorphism and three single nucleotide polymorphisms were identified, but no obvious differences in the genotype distribution and allele frequency of the variants between the control group and any type of OAG were observed. Conclusion Our data suggest that MYOC overexpression is not a cause or an effect of intraocular pressure elevation and that MYOC itself is not associated with OAG.

Abstract
In this study we found that autotrophic methanococci similar to Methanococcus maripaludis obtained up to 57% of their cellular carbon from exogenous amino acids. About 85% of the incorporation was into protein. Primarily nonpolar and basic amino acids and glycine were incorporated; only small amounts of acidic and some polar amino acids were taken up. An additional 10% of the incorporation was into the nucleic acid fraction. Because little CO(2) was formed from the C-amino acids, little metabolism of the amino acids occurred. Therefore the growth stimulation by amino acids was probably due to the sparing of anabolic energy requirements. Of the amino acids incorporated, only alanine was also a sole nitrogen source for these methanococci. In contrast, Methanococcus vannielii and "Methanococcus aeolicus" are autotrophic methanococci which did not incorporate amino acids and did not utilize alanine as a sole nitrogen source. Although glutamine served as a sole nitrogen source for the autotrophic methanococci and Methanococcus voltae, a heterotrophic methanococcus, growth was due to chemical deamination in the medium. M. voltae requires leucine and isoleucine for growth. However, these amino acids were not significant nitrogen sources, and alanine was not a sole nitrogen source for the growth of M. voltae. The branched-chain amino acids were not extensively metabolized by M. voltae. Pantoyl lactone and pantoic acid were readily incorporated by M. voltae. The intact vitamin pantothenate was neither stimulatory to growth nor incorporated. In conclusion, although amino acids and vitamins are nutritionally important to both autotrophic and heterotrophic methanococci, generally they are not subject to extensive catabolism.

Abstract
e22175 Background: The present study analyzed the impact of p53 expression and TP53 codon 72 polymorphism on the prognosis in patients with operated invasive breast cancer. Methods: Two hundred thirty-four patients with ductal breast cancer who underwent surgery with curative intent were enrolled in the present study. The tumor expressions of p53, ER, PR, and HER2 were graded immunohistochemically and TP53 codon 72 polymorphism was determined by a PCR-RFLP assay using genomic DNA extracted from paraffin-embedded tissue. Results: The median age was 49 (range, 24–82) years, and 134 (57.3%) patients were premenopause at the time of diagnosis. Pathologic stages after surgery were as follows: stage I (n=77, 32.9%), stage II (n=110, 47.0%), and stage III (n=47, 20.1%). Tumor overexpression of p53 protein was observed in 59 (25.2%) patients and was associated with an unfavorable relapse-free survival (RFS) in an univariate analysis adjusted to age, stage, and menstrual status. In a multivariate analysis, p53 overexpression was an independent prognostic factor for RFS (HR=2.36; 95% CI=1.09–5.13; p=0.030). However, no associations were observed between the genotype of TP53 codon 72 polymorphism and survival or clinicopathologic characteristics. Conclusions: Overexpression of p53 protein can be considered as a prognostic factor for RFS in the breast cancer patients after surgery. No significant financial relationships to disclose.

Abstract
4039 Background: Polymorphisms in the DNA repair genes may contribute to variation in DNA repair capacity, thereby affecting the risk of carcinogenesis and prognosis of colorectal cancer. Accordingly, the present study analyzed polymorphisms of DNA repair genes and their impact on the prognosis for patients with colorectal cancer. Methods: Three hundred and ninety- seven consecutive patients with curatively resected colorectal adenocarcinoma were enrolled in the present study. The genomic DNA was extracted from fresh colorectal tissue and 14 polymorphisms of DNA repair genes (XRCC1, hMLH1, ERCC2, ERCC4, VARS2[rs2074511, rs2249459], XPA, XPC, POLR2A, POLR2B, RFC1, RFC4, XAB2, DNMT3B) determined using a PCR-RFLP assay. Results: The median age of the patients was 63 years (range, 21–85), and 218 (54.9%) patients had colon cancer and 179 (45.1%) patients rectal cancer. Pathologic stages after surgery were as follows: stage 0/I (n=86, 21.7%), stage II (n=146, 36.8%), stage III (n=145, 36.5%), and stage IV (n=20, 5.0%). Multivariate survival analysis including stage, differentiation, age, and CEA level showed that the survival for the patients with the -93AA genotype of hMLH1 was worse than for the patients with the combined -93GG and GA genotype (overall survival: hazard ratio [HR]=2.953, 95% Confidential Interval [CI], 1.273–6.850, P=0.012; disease-free survival: HR=2.299, 95% CI, 1.417–3.730, P=0.001), whereas the other polymorphisms were not associated with survival. Conclusions: The -93G>A polymorphism of hMLH1 was found to be an independent prognostic marker for patients with colorectal cancer. Accordingly, in addition to the pathologic stage, the analysis of -93G>A polymorphism of hMLH1 can help identify patient subgroups at high risk of a poor disease outcome.

Abstract
e22020 Background: Since the apoptosis induced by caspases may play a role in the prognosis of breast cancer, the present study analyzed the polymorphisms of caspase genes and their impact on the survival in patients with operated invasive ductal breast cancer. Methods: Two hundred eighty patients with breast cancer who underwent surgery with curative intent were enrolled in the present study. The genomic DNA was extracted from paraffin-embedded tissue, and 7 single nucleotide polymorphisms (SNPs) of 6 caspase genes were determined using a PCR-RFLP assay. Results: The median age was 49 (range, 24–82) years, and 157 (56.1%) patients were premenopause at the time of diagnosis. Thirty-six (12.9%) patients underwent breast-conserving surgery. Pathologic stages after surgery were as follows: stage I (n=86, 30.7%), stage II (n=129, 46.1%), and stage III (n=63, 22.5%). Among the target SNPs, CASP6 (rs2301717, +5095G>T) and CASP7 (rs11593766, +11G>T) were found to correlate with relapse-free survival (RFS) after curative surgery in an univariate analysis adjusted to age, stage, histological grade, and the immunohistochemical expression of estrogen receptor and HER2. Meanwhile, multivariate analysis showed that the combined GT and TT genotype of CASP6 (rs2301717) was associated with a better RFS than the GG genotype (HR=0.39; 95% CI=0.19–0.79; p=0.009). However, there was no significant association with overall survival. Conclusions: The CASP6 (rs2301717) polymorphism may be considered as a possible prognostic factor for survival in patients with operated invasive breast cancer. No significant financial relationships to disclose.

Abstract
e15078 Background: Since apoptosis plays a key role in cancer progression, we hypothesized that single nucleotide polymorphisms (SNPs) of apoptosis-related gene can affect survival after curative resection in patients with colorectal cancer. Patients and Methods: Three hundred and ninety seven patients with colorectal cancer who underwent surgery with curative intent were enrolled in the present study. The genomic DNA was extracted from fresh colorectal mucosal tissue, and the 19 SNPs of 15 apoptosis-related genes (CASP3, CASP6–10, FAS, FAS ligand [FASLG], TNSFR1A, TNSFR10B, RIPK1, BCL2, BCL2 ligand [BCL2L], TP53, and PTGS2) were determined using a PCR-RFLP assay. Results: The median age of the patients was 63 years (range, 21–85), and 218 (54.9%) patients had colon cancer and 179 (45.1%) patients rectal cancer. Pathologic stages after surgery were as follows: stage 0/I (n=86, 21.7%), stage II (n=146, 36.8%), stage III (n=145, 36.5%), and stage IV (n=20, 5.0%). Multivariate survival analysis including pathologic stage, differentiation, age, and CEA level showed that relapse-free survival for the patients with the GA+AA genotype of RIPK1 (Receptor interacting serine/threonine kinase 1) +83G>A (rs2272990) was worse than for the patients with the GG genotype (hazard ratio [HR]=1.66, 95% confidence interval [CI]=1.03–2.68, p=0.038). However, no associations were observed between the polymorphisms and overall survival (OS) in a multivariate analysis. Conclusions: RIPK1 gene polymorphism can be considered as a possible prognostic marker for survival after curative resection in patient with colorectal cancer. No significant financial relationships to disclose.

Abstract
e15646 Background: The oophorectomy in isolated metastasis of ovary can lead to long term survival in patients with gastric cancer, but the clinical significance of oophorectomy in stage IV gastric cancer patients is not known well in this time. Methods: We reviewed the medical record of the 55 gastric cancer patients who were metastasis or recurrent in ovary at Dongsan Medical Center, Kimyung University School of Medicine, Daegu, Korea from 1985 to 2008. Results: Twenty-one patients were metastasis to ovary at the time of diagnosis of gastric cancer, and 34 patients were recurrent in ovary after the gastric resection. The mean age was 45.3 ± 11.6 years in metastatic cancer and 46.8 ±12.6 years in recurrent cancer patients. The stage at the time of gastric resection in 34 recurrent patients were I in 3, II in 1, III in 18, and IV in 10. Adjuvant chemotherapy were performed in 26 (76.5%) patients. Oophorectomy were performed in 33 (97.1%) of recurrent cancer, and 17 (81.0%) of metastatic cancer. The 1-year and 2-year survival rate of metastatic cancer were 14.7%, and 0%, and 1-year, 2-year, and 3-year survival rate of recurrent cancer were 47.2%, 18.1%, and 0%, respectively. The median survival duration of metastatic cancer were 8.9 ±1.0 months, and recurrent cancer were 11.4 ±2.3 months. Recurrent cancer were better survival than metastatic cancer patients (p=0.014). The long-term survival (over 2 years) was noted in 5 patients of recurrent cancer patients. The stage of gastric cancer was correlated to overall survival time in total patients (p=0.028). But, the relapse-free survival time after gastrectomy is the only factor to predict survival duration after oophorectomy in recurrent cancer patients (p=0.029). Age, stage of gastric cancer, extent of involvement of ovary, and systemic chemotherapy were not related to survival time of recurrent cancer patients. Conclusions: The survival time in patients with oophorectomy in recurrent gastric cancer was correlated to relapse-free survival time after gastric resection.

Abstract
e15638 Background: The present study analyzed the functional insertion/deletion polymorphism in the promoter region of NKFB1 gene and their impact on the prognosis for patients with gastric adenocarcinoma. Methods: Five hundred and three consecutive patients with surgically resected gastric adenocarcinoma were enrolled in the present study. The genomic DNA was extracted from paraffin-embedded tissue and the -94 insertion/deletion ATTG polymorphism of NFKB1 determined using a PCR- RFLP assay. Results: The NFKB1 promoter gene polymorphism was successfully amplified in 97.8% of the cases. There were no sexual differences in relation to the genotype and allele. No correlation was observed between the frequency of the genotype or allele and the T, N, or M stage. The multivariate survival analysis showed no association between the NFKB1 -94 insertion/deletion promoter polymorphism and the disease-free survival or overall survival of the patients with gastric cancer. Conclusions: The functional NFKB1 promoter polymorphism was not found to be a prognostic marker for Korean patients with surgically resected gastric adenocarcinoma.

Abstract
PURPOSE Wild-type myocilin is known to be secreted extracellularly, but a significant amount of the protein is also present in the endoplasmic reticulum (ER). The present study was undertaken to address whether intracellular myocilin is a true ER resident protein. METHODS Human wild-type myocilin was adenovirally expressed in human trabecular meshwork cells, and general characteristics of both intracellular and extracellular myocilins including molecular weight, pI, glycosylation state, and cleavage site of the signal peptide were examined by biochemical analyses. Topology and decay kinetics of myocilin were also examined by protease protection assay and pulse chase analysis, respectively. The expression pattern and cytopathic effect of myocilin were analyzed in individual cells by immunocytochemistry. RESULTS Intracellular myocilin were very similar to secreted myocilin in characteristics such as molecular weight, pI, glycosylation state, and cleavage site of the signal peptide. The intracellular protein was found to be present in the lumen of the ER where it appeared to be retained without further export to the Golgi apparatus. The kinetics of myocilin turnover clearly showed that it was intrinsically a very stable but incompletely secreted protein. The expression of myocilin was confined to a subset of cells and accompanied by the upregulation of a 78 kDa glucose-regulated protein, suggesting that it was not properly folded or processed in the ER. CONCLUSIONS Based on these findings and the fact that myocilin has no known ER retention signals, the ER localization of wild-type myocilin is likely a consequence of its incomplete secretion due to its misfolding.

Abstract
OBJECTIVE Low-dose whole-body irradiation is known to have anti-inflammatory effects. The objectives of this study were to verify that cytokine augmentation is induced by irradiation in vivo, and to assess the effectiveness of radiation in treating Behçet's disease (BD). METHODS Whole-body and half-body irradiation with single doses of 10cGy, 2Gy and 10Gy were delivered to normal mice, and cytokine and chemokine levels were analyzed in PBMC and sera. BD-like mice were treated with low-dose, half-body 10cGy irradiation. RESULTS In normal mice, PBMC cytokine mRNA levels peaked four days after irradiation. Of the cytokines and chemokines examined, the levels of IL-4, IL-6, IL-12p40, TNF-alpha, TGF-b, MIP-1alpha and IL-18 were all influenced by radiation treatment. Of these, IL-4, an ameliorating factor for BD, was the most elevated following low-dose irradiation (10cGy group). FACS analysis showed intracellular IL-4-staining of 7.24+/-0.92% of PBMC from irradiated mice compared to 1.3+/-0.1% from non-irradiated, normal mice (p<0.005). Serum IL-4 levels were also significantly increased (6.08+/-1.7 pg/ml) relative to control (1.83+/-0.8; p<0.005). CONCLUSION Augmentation of cytokine production may contribute to the anti-inflammatory effects of low dose irradiation and amelioration of BD symptoms in this mouse model.

Abstract
OBJECTIVE The purpose of this work was to provide an analysis of medical costs for HKS/ADHD on the basis of a cost-of-illness study. METHODS A systematic literature review concerning the direct and indirect costs of HKS/ADHD and its related implications was complemented by a special analysis of the German Federal Office of Statistics on ICD-10 F 90. RESULTS An analysis of overall medical costs by the Federal Office of Statistics results in expenses of 142 million euro in 2002 corresponding to ca. 630 euro per patient per year. These values are considerably below the values calculated for the USA. Increased indirect costs related to different implications of the indication were stated in international studies. CONCLUSION A first estimate of the direct costs for HKS/ADHS in Germany has been conducted. A reduction of the difference between the German and the US direct cost values may be expected. An increased level of the indirect costs related to HKS/ADHD may be assumed for Germany and requires further research.

Abstract
Double-outlet left ventricle (DOLV) is conventionally repaired with an extracardiac conduit when pulmonary stenosis is present. We report a case of surgical repair for DOLV with severe pulmonary stenosis where the right ventricular outflow tract was established using a vascular graft patch anteriorly after constructing the posterior wall with autologous tissue. This approach provides excellent hemodynamic repair without the use of an extracardiac conduit and has the major advantage of growth potential.

Abstract
Inhibitory CD94/NKG2A and activating CD94/NKG2C receptors are expressed on natural killer, CD4, and CD8 T cells and recognize human leukocyte antigen (HLA)-E, resulting in the modulation of cytotoxic activity and cytokine production. An imbalance in cytotoxic activity and cytokine production has been implicated in Behcet's disease (BD). The results of this study showed that the NKG2A c.-4258*C, c.338-90*G, and CD94 c.-134*T alleles (P= 0.015, OR = 0.8; P < 0.0001, OR = 0.5; and P= 0.034, OR = 0.8, respectively) were associated with decreased risk and that NKG2A c.284-67_-62del, c.1077*C, and the activating receptor, NKG2C c.305*T were not associated with 345 patients with BD. But a significant difference in NKG2C c.305*T was detected among BD patients with ocular lesions and arthritis (P < 0.0001, OR = 2.1 and P= 0.0001, OR = 1.8, respectively). We already showed in our previous research that HLA-E*0101 also appears to contribute to a reduction in risk through the inhibitory CD94/NKG2A-mediated immune response. This result led us to the analyses of the combined risk of the HLA-E and the NKG2A for BD. Individuals harboring HLA-E*0101, NKG2A c.-4258*C, and c.338-90*G evidenced a reduced risk of BD compared with healthy controls (21.1% vs 40.1%, P < 0.0001, OR = 0.4). By way of contrast, individuals without the HLA-E*0101, NKG2A c.-4258*C, and c.338-90*G alleles evidenced a twofold increased risk of BD (P= 0.014, OR = 2.0). Individuals without HLA-E*0101, NKG2A c.-4258*G/*G, and c.338-90*G evidenced a 4.8-fold increase in BD risk (P= 0.0002, OR = 4.8). Although the effects of these single nucleotide polymorphisms (SNPs) remain unclear, our results indicate that the SNPs of the inhibitory receptor CD94/NKG2A and its haplotypes, as well as its ligand HLA-E, are associated with BD immune systems.

Abstract
8069 Background: The present study was conducted to evaluate the safety and efficacy of alemtuzumab plus CHOP chemotherapy for patients with peripheral T-cell lymphomas (PTCLs). Methods: Twenty patients with newly diagnosed PTCLs were enrolled. The treatment consisted of classical CHOP plus alemtuzumab (10 mg/m2 i.v on day 1 and 20 mg/m2 i.v on day 2 in the first cycle, then 30 mg/m2 i.v on day 1 in the subsequent cycles) based on 3-week intervals. Results: Thirteen complete responses (65.0%) and 3 partial responses (15.0%) were confirmed, giving an overall response rate of 80.0 %. The estimated event-free survival at 1 year was 43.3%. The most severe hematologic adverse event was neutropenia, which occurred with a grade 4 intensity in 18 patients (90.0%). Plus, febrile neutropenia was observed in 11 patients (55.0%). Five patients (25%) experienced CMV (cytomegalovirus) reactivation, while 3 patients developed CMV diseases, such as pneumonitis or retinitis. There were 2 treatment-related deaths. Conclusions: The alemtuzumab plus CHOP chemotherapy seemed to produce active antitumor activity in terms of the complete response rates in patients with PTCLs. However, since high infectious and hematologic toxicities were observed, careful monitoring and early treatment to prevent treatment-related mortality are needed.

Abstract
4125 Background: Vascular endothelial growth factor (VEGF) or its family may be considered to play an important role in lymphangiogenesis and lymphatic tumor spread, thereby affecting prognosis of colorectal cancer. Accordingly, the present study analyzed VEGF gene polymorphisms and their impact on the prognosis for patients with colorectal cancer. Patients and Methods: Four hundred and sixty-five consecutive patients with surgically treated colorectal adenocarcinoma were enrolled in the present study. The genomic DNA was extracted from fresh colorectal tumor tissue and 3 VEGF (-2578C > A, -634G > C, and +936C > T) gene polymorphisms determined using a PCR/DHPLC (Polymerase chain reaction/Denaturing high-performance liquid chromatography) assay. Results: The median age of the patients was 64 years (range, 21–89), and 264 (56.7%) patients had colon cancer and 201 (48.2%) patients rectal cancer. Pathologic stages evaluable (n=464) after surgery were as follows: stage I (n=79, 17.0%), stage II (n=157, 33.8%), stage III (n=157, 33.8%), and stage IV (n=71, 15.3%). Multivariate survival analysis including stage, differentiation, and CEA level showed that survival for patients with the -634CC (overall survival [OS]: hazard ratio [HR]=0.175, P<0.001; progression-free survival [PFS]: HR=0.554, P=0.040) or GC genotype (OS: HR=0.158, P<0.001; PFS: HR=0.630, P=0.044) were better than for patients with the -634GG genotype, whereas the +936TT (OS: HR=65.959, P<0.001; PFS: HR=2.823, P=0.016) or CT genotype (OS: HR=16.116, P<0.001; PFS: HR=3.507, P<0.001) were associated with a worse survival compared to the CC genotype. In haplotype analysis, the -2578A/-634G/+936T haplotype exhibited a significantly worse survival when compared to the wild -2578C/-634G/+936C haplotype (OS: HR=4.670, P<0.001; PFS: HR=3.624, P<0.001). Conclusions: VEGF gene polymorphisms were found to be an independent prognostic marker for patients with colorectal cancer. Accordingly, the analysis of VEGF gene polymorphisms can help identify patient subgroups at high risk of a poor disease outcome. No significant financial relationships to disclose.

Abstract
The nonclassical human leukocyte antigen (HLA)-E and -G molecules have previously been shown to inhibit natural killer- and cytotoxic T-lymphocyte-mediated cell lysis and have also been shown to prevent the proliferation of CD4 T cells and secrete cytokines that appear to be important in the modulation of the Behcet's disease (BD) immune systems. Polymorphisms in the HLA-E and HLA-G genes have been associated with differential expression and function. Thus, we conducted an analysis of the HLA-E and HLA-G alleles using Amplification Refractory Mutation System-polymerase chain reaction (PCR) and PCR-restriction fragment length polymorphism techniques in a study comprising 312 patients with BD and 486 controls. The HLA-E*0101 and HLA-G*010101 alleles were associated with a reduced risk of BD (P = 0.0002, odds ratio (OR) = 0.7 and P = 0.002, OR = 0.7, respectively). By way of contrast, the variants HLA-E*010302, HLA-G*010102, G*0105N alleles and 3741_3754ins14bp were all associated with an increased risk of BD (P < 0.0001, OR = 1.6; P = 0.002, OR = 1.8; P = 0.024, OR = 2.0 and P = 0.003, OR = 1.4, respectively). Individuals carrying both the HLA-E*0101 and the HLA-G*010101 alleles evidenced significantly lower frequency in the patients than in the controls (35.6% vs 49.6%; P < 0.0001, OR = 0.6). These results indicate that variant HLA-E and HLA-G molecules appear to function independently and synergistically, increasing the risk of BD, and may result in an imbalance of lymphocytic functions, which may culminate in the development of BD.
