Abstract
OBJECTIVES In addition to various immunosuppressive agents, belimumab and anifrolumab became available in Japan. We aimed to investigate glucocorticoid-free clinical remission in a single-centre retrospective cohort in October 2023. METHODS Our cohort included patients with SLE who needed to start or increase glucocorticoids for disease activity and were followed up for more than 1 year. We investigated the rate of achievement of clinical remission off corticosteroids (CR off C), defined as no clinical score on the SLEDAI-2K without glucocorticoids, baseline predictors of CR off C, medications used when CR off C was achieved, and flare rates following CR off C. RESULTS Out of the 60 patients followed for an average of 5.4 (±2.6) years, 17 (28.3%) achieved CR off C in 3.6 (±1.2) years after enrolment. Use of belimumab and anifrolumab accounted for eight (47.1%) of the achievers. Among the baseline data, male sex, recent enrolment, high glucocorticoid dose, and detection of immune complex (IC) significantly predicted CR off C, while lupus nephritis (LN) and a low C3 level tended to predict it. In the multivariate analysis, IC detection was the only predictor of CR off C. Clinical flares were observed in 5.9% of the achievers during a median 1.2 years after achievement of CR off C. CONCLUSION In the era of biologics, CR off C was achieved in 28.3% of the patient cohort requiring the start or increase of glucocorticoids for disease activity, with a relatively low rate of flares, suggesting that glucocorticoid-free clinical remission is an achievable target in SLE. IC disease, represented by male sex or nephritis, is likely to benefit from currently available medications.

Abstract
BACKGROUND Duodenal tuberculosis (TB) is extremely rare, and its diagnosis is challenging owing to the lack of specific symptoms and radiological or endoscopic findings. When it leads to gastric outlet obstruction (GOO), diagnosing it accurately and providing appropriate treatment is crucial. However, this is often overlooked. CASE PRESENTATION A 35-year-old man presented with abdominal pain, fullness, vomiting, and weight loss. Upper gastrointestinal endoscopy and radiography revealed nearly pinpoint stenosis with edematous and reddish mucosa in the D1/D2 portion of the duodenum. Computed tomography (CT) showed the duodenal wall thickening, luminal narrowing, multiple enlarged abdominal lymph nodes, and portal vein stenosis. Conventional mucosal biopsy during endoscopy revealed ulcer scars. We initially suspected stenosis due to peptic ulcers; however, chest CT revealed cavitary lesions in both lung apices, suggesting tuberculosis. Due to the suspicion of duodenal TB and the need to obtain deeper tissue samples, endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) was performed. The tissue sample showed caseating granulomas with multinucleated giant cells, and acid-fast bacilli were positive by Ziehl-Neelsen staining. The patient was diagnosed with duodenal TB and subsequent GOO. Because the patient had difficulty eating, surgical intervention was prioritized over antitubercular drugs, and laparoscopic gastrojejunostomy was performed. The patient started an oral diet on the 3rd postoperative day and began antitubercular treatment immediately after discharge on the 11th day. During the 6th month of treatment, endoscopic examination revealed residual duodenal stenosis; however, the bypass route functioned well, and the patient remained asymptomatic. CONCLUSIONS An aggressive biopsy should be performed to diagnose duodenal TB. EUS-FNA has proven to be a useful tool in this regard. Both nutritional improvement and antitubercular treatment were achieved early and reliably by performing laparoscopic gastrojejunostomy for duodenal TB with GOO.

Abstract
OBJECTIVE To clarify seasonal and other environmental effects on the onset of antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). METHODS We enrolled patients with new-onset eosinophilic granulomatosis with polyangiitis (EGPA), microscopic polyangiitis (MPA), and granulomatosis with polyangiitis (GPA) registered in the database of a Japanese multicenter cohort study. We investigated the relationship between environmental factors and clinical characteristics. Seasons were divided into 4 (spring, summer, autumn, and winter), and the seasonal differences in AAV onset were analyzed using Pearson chi-square test, with an expected probability of 25% for each season. RESULTS A total of 454 patients were enrolled, with a mean age of 70.9 years and a female proportion of 55.5%. Overall, 74, 291, and 89 patients were classified as having EGPA, MPA, and GPA, respectively. Positivity for myeloperoxidase (MPO)-ANCA and proteinase 3 (PR3)-ANCA was observed in 355 and 46 patients, respectively. Overall, the seasonality of AAV onset significantly deviated from the expected 25% for each season (P = 0.001), and its onset was less frequently observed in autumn. In ANCA serotypes, seasonality was significant in patients with MPO-ANCA (P < 0.001), but not in those with PR3-ANCA (P = 0.97). Additionally, rural residency of patients with AAV was associated with PR3-ANCA positivity and biopsy-proven pulmonary vasculitis. CONCLUSION The onset of AAV was influenced by seasonal variations and was less frequently observed in autumn. In contrast, the occurrence of PR3-ANCA was triggered, not by season, but by rural residency.

Abstract
A 72-year-old man on hemodialysis due to diabetic nephropathy presented with a fever and penile pain. Although his physical examination was unremarkable, his general condition deteriorated. Penile necrosis was observed by evening on the same day of presentation, and the patient died the next morning. Blood cultures revealed the presence of Group G Streptococcus, leading to a diagnosis of streptococcal toxic shock syndrome (STSS). Autopsy suggested penile necrosis due to septic shock. STSS in hemodialysis patients with vascular calcification, even in the absence of calciphylaxis, can lead to severe organ damage due to ischemia.

Abstract
We herein report the case of a 78-year-old woman who was diagnosed as having disseminated herpes zoster (DHZ) complicated with probable varicella-zoster pneumonia during maintenance therapy for microscopic polyangiitis. Because the patient had severe renal dysfunction, amenamevir administration was started to avoid any neurotoxicity of acyclovir, which is suggested to be optimal for treatment. It ameliorated her symptoms without any adverse events. This is the first report suggesting the efficacy of amenamevir in the treatment of severe herpes zoster infection with coexisting DHZ and probable varicella-zoster pneumonia. Amenamevir could thus be a treatment option for severe varicella zoster virus infections.

Abstract
OBJECTIVES Cyclophosphamide (CYC) has been proposed as a standard induction regimen for interstitial lung disease (ILD) associated with systemic sclerosis (SSc). However, there remain patients with SSc-ILD who are intractable to the therapy. This study aimed to identify factors associated with inadequate response to CYC and investigate how to treat SSc-ILD, especially in the need for glucocorticoids (GCs) combined with CYC. METHODS This retrospective study included consecutive patients diagnosed with SSc-ILD and treated with CYC between 2009 and 2020. Logistic regression models were used to determine the prognostic factors indicating significant progression of ILD (SP-ILD). The clinical findings of patients treated with vs. without GCs were compared. RESULTS Nineteen patients were registered, with a median age of 61.0 years. Fifteen were females, and five were classified into SP-ILD. Baseline high C-reactive protein (CRP) levels and non-widespread or localized ground-glass opacities (GGOs) predicted SP-ILD in multivariable analyses, and the cut-off level of CRP was 0.41 mg/dL. In clinical courses, SSc-ILD with high inflammation temporarily responded to CYC, regardless of the combined use of GCs; however, the therapeutic effects deteriorated soon after stopping CYC. CONCLUSION High CRP levels with non-widespread GGO predicted progressive ILD in patients with SSc treated with CYC.

Abstract
BACKGROUND Chronic rhinosinusitis (CRS) is a common disease, and endoscopic sinus surgery (ESS) is widely performed. However, there is no consensus regarding postoperative pain control after ESS, and postoperative opioid abuse is a problem in many countries. Acetaminophen is reportedly effective for postoperative pain control. Preemptive analgesia has received more attention lately, wherein pain is prevented before it occurs. In this study, we assessed the use of acetaminophen for preemptive analgesia during the perioperative period in ESS. METHODOLOGY This is a retrospective study of 175 patients who underwent ESS, septoplasty, and bilateral inferior turbinate mucosal resection at our hospital from April 2016 to February 2018. In total, 82 patients received 1,000 mg of acetaminophen during surgery and 4 hours after the first dose, while 93 patients did not receive it routinely. We compared these two groups. The primary outcome was the need to use additional analgesics prescribed by the ward physician and the secondary outcomes included postoperative pain, postoperative bleeding, reoperation, blood pressure, and body temperature. RESULTS The use of additional oral and intravenous analgesics was significantly reduced in the patients who received acetaminophen perioperatively. CONCLUSION Preemptive analgesia during the perioperative period of ESS could lead to satisfactory postoperative pain control.

Abstract
Severe digital ischemia (SDI), which presents with digital ulcers, necrosis, or gangrene, has been reported to be a rare manifestation of anti-aminoacyl transfer RNA synthetase (ARS) antibody-positive polymyositis/dermatomyositis or anti-synthetase syndrome. A retrospective study was conducted between 2009 and 2020 at our department to investigate the clinical features of anti-ARS antibody-positive patients with SDI and identify their predictors. A total of 46 patients who were positive for anti-ARS antibody were included, four of whom (8.7%) presented with SDI. The characteristics of the patients with SDI were as follows: the median age was 74 years, with 75% being female; anti-Jo-1 antibody, Raynaud's phenomenon, interstitial lung disease, and myositis were observed in two (50%), four (100%), four (100%), and three patients (75%), respectively. Next, we reviewed the literature of anti-ARS antibody-positive patients with SDI and investigated the predictors of SDI by analyzing a total of 51 patients, including the previously reported five patients with SDI. Multivariable analyses revealed that Raynaud's phenomenon and myositis independently predicted the development of SDI in patients with anti-ARS antibody. In conclusion, digital ulcers, necrosis, or gangrene seem to be more common presentations in our study, and Raynaud's phenomenon and myositis can predict the complications of SDI in anti-ARS antibody-positive patients.

Abstract
Background Primary neuroendocrine tumors of the gallbladder (GB-NETs) are rare, accounting for 0.5% of all NETs and 2.1% of all gallbladder cancers. Among GB-NETs, mixed neuroendocrine–non-neuroendocrine neoplasms of the gallbladder (GB-MiNENs) are extremely rare. Case presentation We present the case of a 66-year-old woman who was referred to us for the management of a gallbladder tumor (incidentally found during abdominal ultrasonography indicated for gallbladder stones). The patient had no history of abdominal pain or fever, and the findings on a physical examination were unremarkable. Blood tests showed normal levels of tumor markers. Imaging studies revealed a mass of approximately 10 mm in diameter (with no invasion of the gallbladder bed) located at the fundus of the gallbladder. A gallbladder cancer was suspected. Therefore, an open whole-layer cholecystectomy with regional lymph nodes dissection was performed. The postoperative course was uneventful, and she was discharged on postoperative day 6. Pathological findings showed GB-MiNENs with invasion of the subserosal layer and no lymph node invasion (classified T2aN0M0 pStage IIA according to the Union for International Cancer Control, 8th edition staging system). Analysis of the neuroendocrine markers revealed positive chromogranin A and synaptophysin, and a Ki-67 index above 95%. Fourteen months after the operation, a local recurrence was detected, and she was referred to another hospital for chemotherapy. Conclusions GB-MiNENs are extremely aggressive tumors despite their tumor size. Optimal therapy should be chosen for each patient.

Abstract
A 62-year-old female patient with systemic lupus erythematosus (SLE) was admitted for cerebral infarction. The magnetic resonance angiography showed focal narrowing of the cerebral arteries that was initially considered as atherosclerosis due to her cardiovascular risk factors. Ten weeks later, she was again admitted for multiple cerebral infarctions. Vessel wall magnetic resonance imaging revealed gadolinium enhancement of the arterial walls of the narrowing lesions, leading to a diagnosis of cerebral arteritis. Based on a literature review, cerebral medium-sized arteritis in SLE likely progresses insidiously during the active phase of SLE, which may later result in occlusion irrespective of disease activity.

Abstract
Objective We investigated the continuation rate, safety and efficacy of treatment with hydroxychloroquine (HCQ) in a retrospective cohort of systemic lupus erythematosus (SLE) in a Japanese municipal hospital. Methods All of the patients with SLE who started treatment with HCQ were included in this study. A retrospective chart review was performed. Our primary outcomes were the continuation rate of HCQ treatment for 1 year and adverse events (AEs) during the treatment. We also investigated the efficacy of HCQ treatment in cases in which treatment with immunosuppressive therapies remained unchanged for the preceding six months. Results Forty-seven patients with SLE were included in this study. Twenty-five patients (53.2%) had AEs. Eleven (64.7%) of the 17 patients who tried the readministration of HCQ could continue HCQ treatment. The continuation rate of HCQ for a period of 1 year was 78.3% (36 of 46 patients). The development of cutaneous lesions was the most frequent adverse event (25.5%) followed by gastrointestinal symptoms (8.5%). In the 16 cases in which the immunosuppressive therapies remained unchanged for at least six months prior to starting HCQ treatment, the SLE disease activity index, anti-DNA antibody, immune complex, and serum complement activity significantly decreased over a period of 1 year, while the prednisolone dose significantly decreased. Conclusion The continuation rate of HCQ treatment was high in an SLE cohort of a Japanese municipal hospital. Although more than half of the patients experienced AEs, the readministration of HCQ was often successful. HCQ treatment provided benefits regarding the clinical and immunological findings in Japanese patients with SLE, which would likely lead to glucocorticoid tapering.

Abstract
Abstract
Four-dimensional flow magnetic resonance imaging (4D flow MRI) provides the detailed visualization of complex blood flow patterns and the evaluation of energy loss. Turbulent kinetic energy estimation (TKE) is reported to have good correlation with irreversible pressure loss in patients having aortic stenosis or great vessel disease. However, little is known about the usefulness of 4D flow MRI and the significance of TKE value in hypertrophic cardiomyopathy (HCM).
Purpose
The aims of this study were to investigate the relationship between TKE value and echocardiographic findings, clinical symptoms and evaluate the usefulness of 4D flow MRI to distinguish hypertrophic obstructive cardiomyopathy (HOCM) from non-obstructive HCM (HNCM).
Methods
From April 2018 to January 2019, 18 hypertrophic obstructive cardiomyopathy (HOCM) and 14 non-obstructive HCM (HNCM) patients underwent 4D flow MRI. We investigated TKE value calculated by 4D flow MRI, echocardiographic findings; left ventricular pressure gradient (LVPG), mitral regurgitation (MR) and clinical symptom.
Results
HOCM was defined by the 30 mmHg or greater of LVPG (HOCM: 87.7±47.3 mmHg, HNCM; 5.8±7.8 mmHg, p<0.001). TKE value in HOCM patients was significantly higher than HNCM (14.2±4.7 mJ vs. 9.0±4.6 mJ, p<0.001). There was a significant positive linear relationship between TKE value and LVPG (r=0.488, p=0.046). There was no significant relationship between NYHA functional class and TKE value (p=0.47) or LVPG (p=0.11). ROC curve analysis showed that optimal cut off point of TKE value between HOCM and HNCM (sensitivity=95%, specificity=62%, AUC=0.798) was 9.270 mJ. Multiple linear regression showed that there was significant association between severity of MR and combination of TKE (p=0.015) or LVPG (p–=0.012). A representative case demonstrated the significant reduction of TKE value 1 week and 3 months after alcohol septal reduction compared with that obtained before the procedure (Figure)
Conclusion
Our findings suggest that 4D Flow MRI can effectively evaluate the energy dissipation associated with LV outflow tract obstruction and TKE value is useful for identifying HOCM. TKE value also can be the novel parameter of the severity of HOCM.

Abstract
Background
Thrombolysis has been recommended for high-risk pulmonary embolism (PE) in ESC guidelines, used as a reference in Japan. Recently, indication of thrombolysis for acute PE has been limited with recent guideline revision. Little is known regarding trends of treatment strategy and mortality in high-risk PE patients.
Purpose
To clarify temporal trends of treatment strategy and short-term outcomes in high-risk PE patients.
Methods
A retrospective analysis of therapeutic interventions and short-term outcomes was performed for 52 consecutive high-risk PE patients including cardiac arrest. According to timing of ESC guidelines update (2000, 2008 and 2014), patients were divided into four time periods: 1992 to 2000, 2001 to 2008, 2009 to 2014, and 2015 to 2018.
Results
Mean age and proportion of male were not different over the period. Nosocomial case decreased from 100% to 25% (p<0.01). Postoperative cases (relative contraindication for thrombolysis) included 43% of all patients. Cardiac arrest and VA-ECMO use were 42% and 21% of all patients. Any thrombolytic therapy including catheter-directed intervention showed a non-significant decrease trend (92%-87%-71%-44%, p=0.067). Temporary or retrieval IVC filter insertion showed a significant downward trend (36%-80%-54%-22%, p=0.025). The entire study 30-day mortality was 23%. There was no significant difference in 30-day mortality over the periods (14%-27%-14%-44%, p=0.303). However, major bleeding decreased significantly (71%-40%-7%-22%, p=0.004) (Table).
Table 1 1992–2000 (n=14) 2001–2008 (n=15) 2009–2014 (n=14) 2015–2018 (n=9) p Age (years) 54±12 59±17 64±13 65±16 0.224 Male 29% 13% 29% 44% 0.269 Any thrombolytic therapy 92% 87% 71% 44% 0.067 Catheter-directed therapy 86% 87% 71% 0% <0.01 with thrombolytics (92%) (83%) (90%) without thromboloytics (8%) (17%) (10%) Only intravenous thrombolysis 8% 7% 7% 44% 0.038 Temporary/retrieval IVC filter 36% 80% 54% 22% 0.025 ICU stay (days) 15±14 10±18 5±4 8±8 0.206 30-day mortality 14% 27% 14% 44% 0.303 Major bleeding 71% 40% 7% 22% 0.004
Conclusion
The temporal analysis identified a decreased trend in any thrombolytic therapy and IVC filter insertion in high-risk PE. The study also found a decreasing trend in major bleeding.

Abstract
Objectives To investigate the sensitivity and specificity of a temporal artery biopsy (TAB) in the diagnosis of giant cell arteritis (GCA) in a single-center retrospective cohort in Japan. Methods A retrospective chart review was performed on consecutive patients who visited our hospital between April 2009 and October 2018 and underwent a TAB. The sensitivity and specificity were calculated for the three pathological standards for a TAB, predetermined according to the pathological criterion of the 1990 American College of Rheumatology (ACR) criteria: A) vasculitis characterized by predominant mononuclear cell infiltration; B) vasculitis with granulomatous inflammation; and C) vasculitis with multinucleated giant cells. We also analyzed the clinical parameters predicting the diagnosis of GCA and the impact of a diagnostic delay of ≥3 months on cardiovascular complications of GCA. Results Our study population was 16 cases in the GCA group and 13 in the non-GCA group. The sensitivity and specificity for Standard A of a TAB were 81% and 85%, respectively, while those for stricter Standards B or C were identical, at 75% and 100%, respectively. These pathological standards, but not any other parameters, significantly predicted the diagnosis. A diagnostic delay tended to cause cardiovascular complications (p=0.057). Conclusion The sensitivity and specificity of the pathological standards of a TAB were favorable in our cohort and were the only predictors for the diagnosis of GCA. Considering the possible impact of a diagnostic delay on cardiovascular complications, the early recognition and prompt initiation of glucocorticoid therapy is needed, even in Japan, where GCA is uncommon.

Abstract
In this paper, we report the development and demonstration of a method to fabricate an all-glass microfluidic cell culturing device without circulation flow. On-chip microfluidic cell culturing is an indispensable technique for cellular replacement therapies and experimental cell biology. Polydimethylsiloxane (PDMS) have become a popular material for fabricating microfluidic cell culture devices because it is a transparent, biocompatible, deformable, easy-to-mold, and gas-permeable. However, PDMS is also a chemically and physically unstable material. For example, PDMS undergoes aging easily even in room temperature conditions. Therefore, it is difficult to control long term experimental culturing conditions. On the other hand, glass is expected to be stable not only in physically but also chemically even in the presence of organic solvents. However, cell culturing still requires substance exchanges such as gases and nutrients, and so on, which cannot be done in a closed space of a glass device without circulation flow that may influence cell behavior. Thus, we introduce a filter structure with micropores onto a glass device to improve permeability to the cell culture space. Normally, it is extremely difficult to fabricate a filter structure on a normal glass plate by using a conventional fabrication method. Here, we demonstrated a method for fabricating an all-glass microfluidic cell culturing device having filters structure. The function of this all-glass culturing device was confirmed by culturing HeLa, fibroblast and ES cells. Compared with the closed glass devices without a filter structure, the numbers of cells in our device increased and embryonic bodies (EBs) were formed. This method offers a new tool in microfluidic cell culture technology for biological analysis and it expands the field of microfluidic cell culture.

Abstract
Screening for oncogenes has mostly been performed by in vitro transformation assays. However, some oncogenes might not exhibit their transforming activities in vitro unless putative essential factors from in vivo microenvironments are adequately supplied. Here, we have developed an in vivo screening system that evaluates the tumorigenicity of target genes. This system uses a retroviral high-efficiency gene transfer technique, a large collection of human cDNA clones corresponding to ~70% of human genes and a luciferase-expressing immortalized mouse mammary epithelial cell line (NMuMG-luc). From 845 genes that were highly expressed in human breast cancer cell lines, we focused on 205 genes encoding membrane proteins and/or kinases as that had the greater possibility of being oncogenes or drug targets. The 205 genes were divided into five subgroups, each containing 34-43 genes, and then introduced them into NMuMG-luc cells. These cells were subcutaneously injected into nude mice and monitored for tumor development by in vivo imaging. Tumors were observed in three subgroups. Using DNA microarray analyses and individual tumorigenic assays, we found that three genes, ADORA2B, PRKACB and LPAR3, were tumorigenic. ADORA2B and LPAR3 encode G-protein-coupled receptors and PRKACB encodes a protein kinase A catalytic subunit. Cells overexpressing ADORA2B, LPAR3 or PRKACB did not show transforming phenotypes in vitro, suggesting that transformation by these genes requires in vivo microenvironments. In addition, several clinical data sets, including one for breast cancer, showed that the expression of these genes correlated with lower overall survival rate.

Abstract
Dumon® Y-stents and Dynamic stents are used to treat carinal stenosis, but their placement severely impairs the expectoration of secretions, making frequent bronchoscopic aspiration necessary. We report here five patients with terminal lung cancer who had stenosis of the lower trachea and main bronchi treated using spiral Z-stents. A long tapered spiral Z-stent was placed in the lower trachea and one main bronchus, and a short straight spiral Z-stent in the contralateral main bronchus. No patients required bronchoscopic aspiration of secretions after stenting. Before stenting, all of the patients were severely dyspnoeic, requiring oxygen and having to sit in the orthopnoeic position. After stenting, the patients' dyspnoea improved, with one patient becoming ambulant without the need for oxygen support. These results suggest that the use of spiral Z-stents in stenosis of the tracheal carina in advanced lung cancer is effective in reducing the need for bronchoscopic aspiration and enhancing quality of life.

Abstract
Abstract
Background: Diffuse optical spectroscopic imaging (DOSI) can be exploited as a marker of tumor blood volume quantified by tissue hemoglobin (tHb) concentration. In DOSI, frequent measurement is possible for breast cancer patients because of its non-invasiveness. The tHb concentration determined by DOSI is expected to be a new biomarker for prediction of breast cancer response to neoadjuvant chemotherapy (NAC).
Purpose: Our objective is to determine whether early change of tumor tHb concentration predicts pathological complete response (pCR) to NAC in patients with operable breast cancer.
Methods: In a prospective study, one hundred patients with primary breast cancer were enrolled for primary objective analysis. The regimens of NAC were according to the standard of care. Patients underwent sequential scans using DOSI at baseline, after 1st course and 2nd course of chemotherapy. The mean value of tHb (tHbmean) concentration of the targeted lesion was measured and the percentage change in tHbmean (ΔtHbmean) concentration was calculated. Receiver operating curve analysis demonstrated diagnostic performance of DOSI for predicting a pCR.
Results: In interim analysis, it was regarded as a good outcome that area under the curve (AUC) for ΔtHbmean after 1nd course was 0.797 (SE 0.104, 95%CI 0.633-0.911), and after 2st course was 0.867 (SE 0.06, 95%CI 0.715-0.956).
Conclusion: DOSI could predict accurately a pCR to neoadjuvant chemotherapy in patients with primary breast cancer.

Abstract
Introduction Syringomatous adenoma of the nipple is a very rare benign tumor. To the best of our knowledge, there are no reports of a syringomatous adenoma of the nipple metastasizing, although these tumors are known to infiltrate locally and to recur if not totally resected. Case presentation Our patient was a 41-year-old Japanese woman who complained of stiffness of her right nipple with abnormal discharge. Local resection of the tumor was performed. The pathological diagnosis was syringomatous adenoma of the nipple, and the resection margin was found to be positive. Accordingly, additional resection was recommended, but our patient did not allow another operation. After 1.5 years of careful follow-up, no local recurrence or distant metastasis has been observed. Conclusion The optimal initial management of syringomatous adenoma of the nipple demands complete resection with histologically negative margins. However, from a cosmetic viewpoint, nipple-sparing resection could represent an alternative option for the treatment of syringomatous adenoma of the nipple.

Abstract
AIMS Abnormalities in the imprinted locus on chromosome 6q24 are the most common causes of transient neonatal diabetes mellitus (6q24-related transient neonatal diabetes). 6q24-Related transient neonatal diabetes is characterized by the patient being small-for-gestational age, diabetes mellitus at birth, spontaneous remission within the first few months and frequent recurrence of diabetes after childhood. However, it is not clear whether individuals with 6q24 abnormalities invariably develop transient neonatal diabetes. This study explored the possibility that 6q24 abnormalities might cause early-onset, non-autoimmune diabetes without transient neonatal diabetes. METHODS The 6q24 imprinted locus was screened for abnormalities in 113 Japanese patients with early-onset, non-obese, non-autoimmune diabetes mellitus who tested negative for mutations in the common maturation-onset diabetes of the young (MODY) genes and without a history of transient neonatal diabetes. Positive patients were further analysed by combined loss of heterozygosity / comparative genomic hybridization analysis and by microsatellite analysis. Detailed clinical data were collected through the medical records of the treating hospitals. RESULTS Three patients with paternal uniparental isodisomy of chromosome 6q24 were identified. None presented with hyperglycaemia in the neonatal period. Characteristically, these patients were born small-for-gestational age, representing 27.2% of the 11 patients whose birth weight standard deviation score (SDS) for gestational age was below -2.0. CONCLUSIONS Abnormalities in the imprinted locus on chromosome 6q24 do not necessarily cause transient neonatal diabetes. Non-penetrant 6q24-related diabetes could be an underestimated cause of early-onset, non-autoimmune diabetes in patients who are not obese and born small-for-gestational age.

Abstract
OBJECTIVES Plumbagin (PL), a naturally occurring quinoid, exerts antitumoral effects in diverse types of cancer cells. However, the effect of PL on tumor cell proliferation in oral squamous cell carcinoma (OSCC) remains poorly understood. In this study, we assessed the efficacy of PL, in human OSCC cells. METHODS The effect of PL on the cell growth and apoptosis of OSCC cell lines was evaluated using MTT and Annexin V assays, respectively. The effect of PL on mitochondrial membrane potential loss and reactive oxygen species (ROS) generation was evaluated using flow cytometry analysis. RESULTS MTT assay showed that PL dose-dependently suppressed OSCC cell growth, with IC50 values ranging from 3.87 to 14.6 μM. Flow cytometry analysis revealed that PL treatment resulted in a significant decrease in mitochondrial membrane potential and an increase in the number of apoptotic cells. Notably, ROS generation was significantly elevated after PL treatment. Furthermore, a ROS scavenger, N-acetylcysteine (NAC), clearly suppressed the decrease in mitochondrial membrane potential, increase of caspase-3/7 activity, and apoptosis after PL treatment. CONCLUSION This study provides the considerable evidence of the tumor-suppressive effect of PL, thereby highlighting its therapeutic potential for OSCC treatment.

Abstract
AIMS To investigate the molecular and clinical characteristics of the largest series of Japanese patients with glucokinase maturity-onset diabetes of the young (GCK-MODY), and to find any features specific to Asian people. METHODS We enrolled 78 Japanese patients with GCK-MODY from 41 families (55 probands diagnosed at the age of 0-14 years and their 23 adult family members). Mutations were identified by direct sequencing or multiplex ligation-dependent probe amplification of all exons of the GCK gene. Detailed clinical and laboratory data were collected on the probands using questionnaires, which were sent to the treating physicians. Data on current clinical status and HbA1c levels were also collected from adult patients. RESULTS A total of 35 different mutations were identified, of which seven were novel. Fasting blood glucose and HbA1c levels of the probands were ≤9.3 mmol/l and ≤56 mmol/mol (7.3%), respectively, and there was considerable variation in their BMI percentiles (0.4-96.2). In total, 25% of the probands had elevated homeostatic assessment of insulin resistance values, and 58.3% of these had evidence of concomitant Type 2 diabetes in their family. The HbA1c levels for adults were slightly higher, up to 61 mmol/mol (7.8%). The incidence of microvascular complications was low. Out of these 78 people with GCK-MODY and 40 additional family members with hyperglycaemia whose genetic status was unknown, only one had diabetic nephropathy. CONCLUSIONS The molecular and clinical features of GCK-MODY in Japanese people are similar to those of other ethnic populations; however, making a diagnosis of GCK-MODY was more challenging in patients with signs of insulin resistance.

Abstract
AIM To investigate the effect of catechins on vascular endothelial growth factor (VEGF) production and cyclooxygenase-2 (COX-2) expression in human dental pulp cells (HDPC) stimulated with bacteria-derived factors or pro-inflammatory cytokines. METHODOLOGY Morphologically fibroblastic cells established from explant cultures of healthy human dental pulp tissues were used as HDPC. HDPC pre-treated with catechins, epigallocatechin-3-gallate (EGCG) or epicatechin gallate (ECG), were exposed to lipopolysaccharide (LPS), peptidoglycan (PG), interlukin-1β (IL-1β) or tumour necrosis factor-α (TNF-α). VEGF production was examined by enzyme-linked immunosorbent assay, and COX-2 expression was assessed by immunoblot. RESULTS EGCG and ECG significantly reduced LPS- or PG-mediated VEGF production in the HDPC in a dose-dependent manner. EGCG also prevented IL-1β-mediated VEGF production. Although TNF-α did not enhance VEGF production in the dental pulp cells, treatment of 20 μg mL(-1) of EGCG decreased the level of VEGF. In addition, the catechins attenuated COX-2 expression induced by LPS and IL-1β. CONCLUSIONS The up-regulated VEGF and COX-2 expressions in the HDPC stimulated with these bacteria-derived factors or IL-1β were diminished by the treatment of EGCG and ECG. These findings suggest that the catechins may be beneficial as an anti-inflammatory tool of the treatment for pulpal inflammation.

Abstract
Abstract
Background: The St.Gallen consensus guideline recommends the sequential administration chemotherapy followed by of endocrine therapy as postoperative therapy for the higher risk ER-positive breast cancer patients based on results of a single study (Albain et al, Lancet 2009). In metastatic settings however, several trials conducted in the 1980's demonstrated that tumor response rates were higher when chemotherapy and tamoxifen were concomitantly administered, than when chemotherapy and tamoxifen administered were given sequentially. In the preoperative settings, pathological complete response (pCR) rate can be used a surrogate marker to predict event-free survival or overall survival in Luminal B(HER2-negative) breast cancer. We therefore designed a prospective randomized safety and efficacy trial in order to test a hypothesis that the concomitant administration of an aromatase inhibitor and chemotherapy improves pathological complete response(pCR) rate than chemotherapy alone in the preoperative setting.
Trial design: The trial is a prospective, multi-center, randomized comparison of chemotherapy alone versus concomitant chmo-endocrine therapy evaluating the efficacy in terms of pCR rate and safety in preoperative settings in patients with Luminal B (HER2-negative) breast cancer. 94 patients were to be accrued into this trial.
- arm A (control): 12 cycles of weekly paclitaxel(80mg/m2) followed by 4 cycles of every 3-week AC(Doxorubicine 60mg/m2, Cyclophosphamide 600mg/m2).
- arm B (experimental): The same chermotherapy as arm A and anastrozole in postmenopausal patients or anastrozole+leuprolerine in premenopansal patients.
Eligibility criteria: 1)Female patients with operable and histologically confirmed invasive breast cancer; 2)HER2-negative; 3)Either ER -positive or PgR-positive; 4)Either Ki67-LI> = 14% and NG> = 2 or NG = 3 regardless of Ki67-LI.
Endpoints : Primary endpoint is the pCR rate. Secondary endpoints are the clinical response rate(RECIST), the adverse events(CTC-AE ver.4.0), the breast conserving rate and the health related quality of life.
Statistical Considerations : The pCR rates in the control arm and the experimental arm are expected to be 10% and 25%, respectively. In order to show the superiority of the experimental arm with an alfa error at 5% and beta error at 20%, calculated number of patients needed were 96.
Present Accrual and Target Accrual: As of June 06, 2013, 18 patients were enrolled from 8 institutions.

Abstract
CONTEXT Lymphoepithelial cysts with sebaceous glands of the pancreas are extremely rare, with only 7 cases, including this case, published in English literature. CASE REPORT We herein present the case of a 67-year-old Asian man who underwent a resection of a lymphoepithelial cyst of the pancreas during the follow up care for lung cancer. Fourteen years previously he underwent a right lower lobectomy at the right segment nine for lung cancer. A 20 mm mass in the body of the pancreas was identified by CT scan 4 years ago, and the diagnosis was intraductal papillary mucinous neoplasm (IPMN) at that time. Over a 5-year period, this mass grew to 42 mm without dilatation of the main pancreatic duct. The preoperative evaluation, including endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA), indicated a cystic neoplasm with suspicion of malignancy. Intraoperative frozen section revealed a squamous-lined cyst accompanied by sebaceous glands without any malignant findings. Following this pathological finding, resection of the cyst was performed. Consequently, microscopic examination revealed that it was a lymphoepithelial cyst with sebaceous glands of the pancreas. CONCLUSIONS Pancreatic lymphoepithelial cysts can be cured by conservative resection, but if they are asymptomatic and are diagnosed before surgery, no treatment is necessary. To our knowledge, this is the first ever published case of a lymphoepithelial cyst with sebaceous glands of the pancreas, which was found during the follow up care for lung cancer.

Abstract
BACKGROUND Neuroimmunological disorders are involved in the pathogenesis of atopic dermatitis (AD), partly through enhanced sensory nerve-skin mast cell interaction. Cell adhesion molecule 1 (CADM1) is a mast-cell adhesion molecule that mediates the adhesion to, and communication with, sympathetic nerves. OBJECTIVES To investigate the role of mast cell CADM1 in the pathogenesis of AD, CADM1 expression levels by comparing between lesional and nonlesional skin mast cells of an AD mouse model, which was developed by repeated application of trinitrochlorobenzene, and to examine, in cocultures, how the alterations in CADM1 detected in lesional mast cells might affect the sensory nerve-mast cell interaction. METHODS AD-like lesional and nonlesional skin mast cells were collected separately by laser capture microdissection. CADM1 expression was examined by reverse transcription-polymerase chain reaction and CADM1 immunohistochemistry. In cocultures, adhesion between dorsal root ganglion (DRG) neurites and IC2 mast cells was analysed by loading a femtosecond laser-induced impulsive force on neurite-attendant IC2 cells, while cellular communication was monitored as the IC2 cellular response ([Ca(2+)]i increase) after nerve-specific stimulant-induced DRG activation. RESULTS AD-like lesional mast cells expressed three-fold more CADM1 transcripts than nonlesional cells. This was supported at the protein level, shown by immunohistochemistry. In coculture, CADM1 overexpression in IC2 cells strengthened DRG neurite-IC2 cell adhesion and doubled the population of IC2 cells responding to DRG activation. A function-blocking anti-CADM1 antibody abolished these effects in a dose-dependent manner. CONCLUSIONS Increased expression of CADM1 in mast cells appeared to be a cause of enhanced sensory nerve-mast cell interaction in a hapten-induced mouse model of AD.

Abstract
Abstract
Objectives: Optical mammography (O-MMG), which utilizes near-infrared light for the detection of abnormal breast tissue, can be a potentially useful and non-invasive tool for the screening of breast cancer patients. Here we report on the preliminary results of our clinical trial using a time-resolved O-MMG system developed by Hamamatsu Photonics (Hamamatsu, Japan). In our past examination, negative results included cases with mismatch for breast cup because of small breast, lesion outside of cup because of big breast, and bad positioning. So, size and shape of a gantry was improved (3 cup sizes; S, M and L cup). We reported the initial experience of the improved O-MMG systems.
Materials and Methods: In principle, the technique involves sequential irradiation of the breast tissue with a pulsed laser with a wavelength of 760, 800 and, 830nm, which is then detected by the variable capacity gantry at multiple sites after passing through the breast tissue. Measurement time has improved to about 7 minutes (a third of the conventional measurement time). The data are analyzed and tomographic images of the absorption coefficient of the breast are then reconstructed based on our tomographic reconstruction algorithm. Between October 2011 and May 2012, fifteen patients with breast cancer and one patient with fibroadenoma participated in the trial.
Results: In patients with breast cancer, S cup was used for one patient, M cup for 12 patients and L cup for two patients. Five patients after neo-adjuvant chemotherapy were excluded from the analysis. The lesions were depicted as an area of high hemoglobin concentration in 7 of 10 patients with cancer. One lesion of fibroadenoma was also identified as an area of high hemoglobin concentration.
Conclusion: Further examination with our new O-MMG systems will be of interest.

Abstract
We examined the effects of 5-Gy radiation on the expression of hypoxia-inducible factor-1α (HIF-1α) and the radiosensitivity of five human oral squamous cell carcinoma (OSCC) cell lines (SAS, Ca9-22, TT, BSC-OF and IS-FOM). In all of the cell lines, HIF-1α was expressed in mRNA, and radiation had no influence on gene transcription. The number of apoptotic cells increased 72 h after irradiation in cell lines SAS, Ca9-22 and TT cells, indicating low transcriptional levels of HIF-1α, and the levels of non-cleaved caspase-3, an executioner of apoptosis, and non-cleaved poly (adenosine diphosphate-ribose) polymerase (PARP), a marker of DNA damage early in apoptosis, decreased simultaneously. Conversely, radiation failed to induce apoptosis or to decrease expression of non-cleaved caspase-3 and PARP in cell lines BSC-OF and IS-FOM cells that expressed high levels of HIF-1α. BSC-OF and IS-FOM cells exhibited high migratory capacity. When CoCl(2) was present in the medium, HIF-1α expression increased along with the survival of Ca9-22 cells after radiation exposure. These results suggest that OSCC cells expressing high levels of HIF-1α are resistant to radiation. HIF-1α can be used to control the short-term radiosensitivity of cells.

Abstract
Abstract
Background: Activation of lipid metabolism is an early event of carcinogenesis and a central hallmark of many cancers including breast cancer. Recent findings argue that stearoyl CoA desaturase-1 (SCD1), a key regulator of the fatty acid (FA) composition and the endoplasmic reticulum resident enzyme that converts saturated FA (SFA) into monounsaturated FA (MUFA) is a novel regulator of carcinogenesis. The distinctive lipids composition of membrane in cancer cells and the biological functions of SCD1, however, still remain uncertain. Imaging mass spectrometry (IMS) is a mass spectrometry-based analyzing technique that enables visualization of the individual molecules without requiring antibodies. It allows comprehensive detection of a wide range of biomolecules, such as lipids. We attempted to visualize the localization of lipids in breast cancer by IMS for better understanding of cancer proliferation.
Materials and methods: 13 specimens were obtained from the primary breast cancer patients. All were Japanese woman and aged 41–86 years (mean 61.5y.o.). Only one patient received preoperative systematic therapy. 6 were estrogen receptor (ER) and/or progesterone receptor (PgR) positive and human epidermal growth factor receptor 2 (HER2) negative, 2 were ER and/or PgR positive and HER2 positive, 2 were both ER and PgR negative and HER2 positive and 2 were triple negative.
IMS: Samples were immediately chilled in liquid Hexan and stored at −80°. All specimens were sliced into 10 mm thin sections, mounted onto one indium-tin oxide-coated glass slides (Bruker Daltonics) and then sprayed by 2,5-Dihydroxybenzoic acid. Matrix assisted laser desorption ionization (MALDI) technique was used as a soft ionization method. We used time of flight (TOF)/TOF type instrument (Ultraflex, Bruker Daltonics) and all the spectrum were acquired automatically using Fleximaging software (Bruker Daltonics). Each spectral intensity at any mass-to-charge ratio (m/z) was measured at 16 regions of interest (ROI); 13 ROI were picked up from cancerous parts and 3 were from non-cancerous parts. Spectral intensities were compared and statistical analysis was performed by Mann Whitney test. The software was also used to create two-dimensional ion-density maps.
Results: In the cancerous parts of all the 13 specimens, two distinct peaks of the molecular ions were detected at m/z 798.5 and 810.5, which were not found in the non-cancerous parts. Median intensity of the molecular ions at m/z 798.5 and 810.5 were 38.9 and 3.18 in the cancerous part, while they were 0.84 and 1.02 in the non-cancerous part (p=0.010 and 0.015, respectively). Tandem mass spectrometry analysis for these two molecules revealed that they were two kinds of phosphatidylcholine (PC), PC (16:0/18:1) and PC (18:0/18:1). Localization of the individual PC was visualized by means of IMS, which showed that in cancerous part accumulation of PCs containing MUFA was more pronounced than those containing SFA only. Conclusion:
Two kinds of PC containing MUFA were found to highly accumulate in cancerous parts, which may suggest involvement of SCD1 in the membrane composition regulation and cancer proliferation. Further studies may thus be warranted to explore the relation between PC localization and the SCD1 expression.

Abstract
Objectives: To examine optical properties of breast cancer by time-resolved spectroscopy.
Materials and Methods: We irradiated a pulsed laser of 760, 800, and 830 nm wave-length lights at multiple sites of both breasts including the site just above the cancer and detected the light transmitted through the breast with TRS-20SH (Hamamatsu Photonics K.K.). Absorption coefficient (μa), reduced scattering coefficient (μs'), total hemoglobin (tHb), and oxygen saturation (SO2) of the breast were calculated by photon diffusion equation. The clinical trial started in January 2007. A total of one hundred nine breast cancer patients participated in the trial and written informed consent were obtained from all of the patients. Results: In 800 nm wave-length, absorption coefficient (μa) of breast cancer tissue was significantly high, compared with contra-lateral normal breast (cancer:0.0677± 0.0293, normal breast;0.0479± 0.0161, p<0.001).
The result was the same in 760, and 830 nm. There was no difference in reduced scattering coefficient (μs') between breast cancer tissue and contra-lateral normal breast (800 nm cancer:9.070±1.217, normal breast;9.348±1.243, p=0.10). The tHb of breast cancer tissue was significantly high, compared with normal breast (cancer:31.0± 14.7, normal breast;21.0±8.2, p<0.001). There was no difference in oxygen saturation (SO2) between breast cancer tissue and contra-lateral normal breast (cancer:72.8±4.1, normal breast;73.8±4.5, p=0.08).
Conclusion: Absorption coefficient (μa) and tHb increased in breast cancer, whereas reduced scattering coefficient (μs') did not.

Abstract
The cell cycle of donor cells and recipient cytoplasts are important factors affecting development of nuclear transferred (NT) embryos. We previously showed that bovine NT embryos using pre-activated cytoplasts and early G1 cells had a high in vitro developmental rate (SSR, 2008, 41st Annual Meeting). The objective of the present study was to evaluate the effects of donor cell cycle (early G1 or G0 phase) and the timing of oocyte activation on fetal development of bovine NT embryos. Adult fibroblasts from ear skin tissue of Japanese black cattle were used as donor cells. The G0 phase cells were synchronized by serum-starvation, and the G1 phase cells were prepared from actively dividing M phase cells. NT embryo production was performed by 2 kinds of protocols as follows: 1) recipient oocytes were activated by Ca ionophore (CaI), followed with cycloheximide (CH) for 2 h, and fused with synchronized donor cells followed with cytochalasin D (CD) and CH for 1 h, then CH for 4 h (pre-activated), 2) unactivated oocytes were fused with synchronized donor cells and activation was performed by CaI 1 h after fusion, followed by with CD and CH 1 h, then CH for 4 h (post-activated). After activation treatments, NT embryos were cultured in IVD101 medium for 7 days. Then, blastocysts were transferred to recipient cows. Diagnosis of pregnancy was made by ultrasonography at days 30, 60, and 90 (Day 0 = the day of embryo transfer). As shown in Table 1, the blastocyst formation rate of the NT embryos derived from early G1 cells in the pre-activated group was higher than that from G0 cells in the post-activated group (36% v. 23%, P < 0.05). After embryo transfer, 29, 67, and 50% of recipient cows were pregnant at Day 30 in G0 post-, G1 post-, and G1 pre-activated groups, respectively. However, only 1 embryo (14%) of G0 post-activated group developed to term. In conclusion, bovine NT embryos using early G1 cells and pre-activated cytoplasts showed a high blastocyst formation rate, but the full-term development of bovine NT embryos could not be improved by using early G1 cells and pre-activated cytoplasts.

Abstract
BACKGROUND AND OBJECTIVE Because human gingival fibroblasts (HGFs) are the predominant cells in periodontal tissues, we hypothesized that HGFs are contributed to receptors for components of bacteria. In this study, we focused on expression and function of nucleotide binding oligomerization domain 2 (NOD2) in HGFs, which is a mammalian cytosolic pathogen recognition molecule. MATERIAL AND METHODS Expression of NOD2 in HGFs was examined by reverse transcriptase-polymerase chain reaction (RT-PCR) and flow cytometry. Production of interleukin (IL)-6, IL-8, cc chemokine ligand2, cxc chemokine ligand10 (CXCL10) and CXCL11 from HGFs was examined by enzyme-linked immunosorbent assay (ELISA). We used RT-PCR and immunohistochemistry to detect the NOD2 expression in human gingival tissues. RESULTS We found clear NOD2 expression in HGFs. Upon stimulation with NOD2 agonist, muramyldipeptide (MDP), production of proinflammatory cytokines was enhanced. Moreover, MDP-induced production of proinflammatory cytokines was inhibited in a different manner by mitogen-activated protein kinase inhibitors and phosphatidylinositol 3-kinase inhibitor. Furthermore, MDP enhanced CXCL10 and CXCL11 productions by tumor necrosis factor-alpha (TNF-alpha)- or interferon-gamma (IFN-gamma)-stimulated HGFs, although MDP alone did not induce these chemokines. TNF-alpha and IFN-gamma increased NOD2 expression in HGFs. In addition, we detected NOD2 expression in mononuclear cells and HGFs in periodontally diseased tissues. CONCLUSION These findings indicate that MDP which induces production of cytokines and chemokines from HGFs is related to the pathogenesis of periodontal disease.

Abstract
A 46-year-old woman was admitted to our hospital with hepatic encephalopathy due to alcoholic liver disease. A hepatic nodule (20 mm in diameter) in S7 was enhanced in the early phase of contrast CT. No significant findings were observed in the late phase of contrast CT and SPIO MRI. The late phase of CT during hepatic arteriography showed corona-like enhancement of the nodule. The nodule was diagnosed as a hypervascular hyperplastic nodule, based on histological examinations and immunohistochemical results with antibodies against CD68 and CD34.

Abstract
We have reported that CXCL16, a recently discovered transmembrane chemokine, is expressed in human gingival fibroblasts (HGF). However, it is not known whether HGF express CXCR6, the receptor for CXCL16, or CXCL16 affects HGF biology. We have shown that HGF expressed CXCR6 by reverse transcription-polymerase chain reaction and flow cytometric analysis. Moreover, we elucidated that tumour necrosis factor (TNF)-alpha and cytosine-guanine dinucleotide (CpG) DNA (Toll-like receptor-9 ligand) treatment enhanced CXCR6 expression by HGF. Interleukin (IL)-4, IL-13 and CpG DNA up-regulated CXCR6 expression by TNF-alpha-stimulated HGF. On the other hand, IL-1beta and interferon-gamma inhibited CXCR6 expression on TNF-alpha-treated HGF. CXCL16 treatment induced HGF proliferation and phosphorylation of extracellular regulated kinase (ERK) and protein kinase B (AKT) in HGF. In conclusion, HGF expressed CXCR6 functionally, because CXCL16 induced HGF proliferation and ERK and AKT phosphorylation in HGF. These results indicate that CXCL16 may play an important role in the pathogenesis and remodelling in periodontally diseased tissues.

Abstract
A case of pulmonary alveolar microlithiasis occurring in an inbred family is presented. A genome-wide analysis of the patient's genomic DNA using a high-density single nucleotide polymorphism (SNP) array revealed a small intragenetic mutation at SLC34A2. The results suggest that the high-density SNP array has the power to identify a recessive disease gene(s) even in the analysis of only a single inbred patient.

Abstract
CD45, also referred to as the leukocyte common antigen (LCA), is selectively expressed on nucleated hematopoietic cells in healthy individuals. It is also widely expressed in various types of hematologic malignancies--although 10% of acute lymphoblastic leukemia and more than 50% of multiple myeloma have been reported to lack its expression. In this paper, we report a rare case of CD45-negative non-Hodgkin's lymphoma (NHL) that affected the thyroid gland.

Abstract
BACKGROUND AND OBJECTIVE It has been reported that T helper 2 (Th2) cells are related to exacerbation of periodontal disease. However, it is uncertain how the migration of Th2 cells is controlled. In this study, we examined the expression of CC chemokine ligand 17 (CCL17), which is a Th2 chemokine, in periodontal tissues. Moreover, we investigated the effects of cytokines and toll-like receptor (TLR) ligands on the production of CCL17 by human gingival fibroblasts (HGFs). MATERIAL AND METHODS We used immunohistochemistry and reverse transcriptase-polymerase chain reaction (RT-PCR) to detect CCL17 in periodontal tissues. HGFs were exposed to cytokines and TLR ligands. Expression of CCL17 was examined by RT-PCR and enzyme-linked immunosorbent assay. We used signal transduction inhibitors in some experiments. RESULTS Both CCL17 and its receptor, CC chemokine receptor 4 (CCR4), were expressed in diseased periodontal tissues. A combination of tumour necrosis factor alpha (TNF-alpha) and interleukin (IL)-4/IL-13 increased CCL17 expression. Moreover, treatment of HGFs with a low dose of interferon-gamma (IFN-gamma) in combination with TNF-alpha and IL-4 or IL-13 had synergistic effects on the production of CCL17, whereas a high dose of IFN-gamma inhibited CCL17 production. Furthermore, Escherichia coli (E. coli) lipopolysaccharide (TLR4 ligand) and Pam3CSK4 (TLR2 ligand) inhibited CCL17 production by TNF-alpha + IL-4-stimulated HGFs, while CpG DNA (TLR9 ligand) enhanced TNF-alpha + IL-4 induced-CCL17 production by HGFs. Furthermore, a c-Jun NH2 terminal kinase (JNK) inhibitor, a phosphatidylinositol-3-kinase (PI3K) inhibitor and a nuclear factor kappa B (NF-kappa B) inhibitor inhibited CCL17 production by HGFs. CONCLUSION These results suggest that the CCL17 produced by HGFs may be involved in the migration of Th2 cells into inflamed tissues, and provide evidence that CCL17 production is controlled by cytokines and TLR ligands in periodontal disease.

Abstract
Periodontal disease is an inflammatory disorder characterized by the involvement of chemokines that are important for the recruitment of leucocytes. Several cytokines, including tumour necrosis factor alpha (TNF-alpha), are involved in regulating levels of chemokines in periodontal disease. CXC chemokine ligand 10 (CXCL10) is a chemokine related to the migration of T helper 1 cells. In this study, we examined CXCL10 expression in human gingival fibroblasts (HGFs). Moreover, we investigated the effects of adrenomedullin (AM), which is a multi-functional regulatory peptide, on the production of CXCL10 by HGFs. We revealed that TNF-alpha stimulation induced CXCL10 production by HGFs. HGFs expressed AM and AM receptors, calcitonin-receptor-like receptor (CRLR) and receptor-activity-modifying protein (RAMP) 2, mRNAs constitutively. AM treatment supressed CXCL10 production by TNF-alpha-stimulated HGFs. Moreover, we elucidated that AM produced by HGFs inhibited CXCL10 production by HGFs, because AM antagonist enhanced CXCL10 production by HGFs. TNF-alpha treatment enhanced CRLR and RAMP2 mRNA expression in HGFs. Furthermore, AM is expressed in human periodontal tissues, including both inflamed and clinically healthy tissues. These results suggest that the CXCL10 produced by HGFs may be involved in the migration of leucocytes into inflamed tissues and related to exacerbation of periodontal disease. AM might be a therapeutic target of periodontal disease, because AM can inhibit CXCL10 production by HGFs.
