Abstract
Recombinant human parathyroid hormone (PTH) analogues reduce fractures in patients with osteoporosis by enhancing bone formation and improving bone quality. Furthermore, many studies have demonstrated the efficacy of these analogues in diseases such as PTH-deficient hypoparathyroidism, bisphosphonate-related osteonecrosis of the jaw and hypophosphatasia. Further studies are needed to examine the long-term effects and the safety of these analogues in children and cancer patients.

Abstract
BACKGROUND The mechanisms of the development of symptoms in functional dyspepsia (FD) patients have not been fully elucidated. We previously reported that acid directly infused into the stomach causes dyspeptic symptoms in asymptomatic healthy controls (HCs); however, the response to acid infusion of FD patients was not determined. AIM To investigate the severity of dyspeptic symptoms induced by direct acid infusion in FD subjects and HCs. METHODS This was a multi-centre, cross-over, randomised, double-blind study in 23 FD subjects and 32 HCs. FD was defined using the Rome III criteria. All subjects were Helicobacter pylori negative. Each subject received two tests; 0.1 mol/L hydrochloric acid and water infused into the stomach. The presence and severity of 12 dyspeptic symptoms were assessed using a visual analogue scale. RESULTS The proportion of subjects developing symptoms by acid or water infusion was significantly greater in FD subjects than HCs. All of the FD subjects experienced at least one symptom by water or acid infusion. In the FD subjects, the severity of symptoms was significantly greater with acid infusion than water infusion. The severity of symptoms in total and the scores for eight of the 12 symptoms induced by acid infusion was significantly greater in FD subjects than in HCs. CONCLUSIONS The severity of dyspeptic symptom generation induced by direct acid infusion into the stomach was significantly greater in functional dyspepsia subjects than in healthy controls, suggesting that hypersensitivity to acid is one of the important mechanisms of the development of symptoms in functional dyspepsia patients.

Abstract
Endothelial nitric oxide synthase (NOS3) is one of the enzymes influencing nitric oxide (NO) function in the human brain. NO is a gaseous neurotransmitter that is involved in a variety of mechanisms in the central nervous system, such as N-methyl-D-aspartate receptor activation and oxidative stress. The evidence from animal pharmacological studies and postmortem studies supports an association between NO and psychotic disorders. Methamphetamine (METH) use disorder is a known psychotic disorder, and we therefore conducted a gene-based case-control study between tagging single nucleotide polymorphisms (SNPs) (rs2070744, rs1799983) in NOS3 and METH-induced psychosis in Japanese subjects (183 with METH-induced psychosis and 267 controls). Written informed consent was obtained from each subject. No significant association was found between any tagging SNP in NOS3 and METH-induced psychosis in the allele/genotype-wise or haplotype-wise analyses. In conclusion, we suggest that NOS3 might not contribute to the risk of METH-induced psychosis in the Japanese population.

Abstract
OBJECTIVE Impaired glucose metabolism is common in acromegaly, but it is not clear how glucose metabolism is impaired or what predicts its restoration after cure of the disease. To identify factors involved in the impairment of glucose metabolism in acromegaly, we evaluated clinical parameters before and immediately after surgical cure of the disease. DESIGN AND METHODS We retrospectively analyzed clinical data of 92 consecutive Japanese patients with acromegaly who underwent successful pituitary surgery. Patients who had received medical therapy for acromegaly or insulin treatment for diabetes were excluded. We evaluated insulin resistance (IR) and pancreatic β-cell function in addition to GH and IGF1 levels before and after surgery. Results In this study of Japanese patients with acromegaly, average body mass index (BMI) was 23.4, and no patient had a BMI>30. IR was involved in the impairment of glucose metabolism, which was restored upon surgical cure of acromegaly if β-cell function was preserved. Insufficient β-cell function did not improve after normalization of GH/IGF1 and was associated with impaired glucose metabolism before and after surgery. RESULTS of receiver operating characteristic analysis of preoperative clinical parameters suggest that insulinogenic index (IGI) >0.50 best predicts restoration of normal glucose metabolism upon cure of acromegaly in Japanese patients. CONCLUSIONS IR impairs glucose metabolism in acromegaly. Once β-cell function is impaired, abnormal glucose metabolism persists even after cure of acromegaly. IGI>0.50 indicates that β-cell function is preserved in non-obese Japanese patients with acromegaly.

Abstract
Single immunoglobulin (Ig) interleukin-1R-related molecule (SIGIRR) is an Ig-like membrane protein critical for negative regulation of Toll-like receptor (TLR)-4-mediated signalling. We investigated SIGIRR expression and its regulation mechanism in intestinal epithelial cells (IECs) during inflammation. Endoscopic biopsy specimens were obtained from active and inactive colonic mucosa of ulcerative colitis (UC) patients, then SIGIRR expression was examined using real-time polymerase chain reaction (PCR) and immunohistochemistry (IH). Mice experimental colitis models were established by administrations of sulphonic acid (TNBS) and dextran sodium sulphate (DSS), and epithelial expression of SIGIRR was examined using real-time PCR, IH and flow cytometry. The effects of lipopolysaccharide (LPS) and tumour necrosis factor (TNF)-α on SIGIRR expression were evaluated in vitro using cultured IECs. To elucidate SIGIRR expression regulation in IECs, binding ability of the transcription factor SP1 at the responsive element of the SIGIRR promoter was examined using gel-shift and chromatin immunoprecipitation (ChIP) assays. In human colonic samples, SIGIRR was expressed mainly in IECs at levels significantly higher in inactive compared to active mucosa. In the mice, SIGIRR colonic expression decreased rapidly after colitis development and returned gradually to basal levels. Experimental colitis-mediated down-regulation of SIGIRR in IECs was also confirmed by IH and flow cytometry results. Further, inflammatory conditions induced by TLR ligands and TNF-α caused significant down-regulation of SIGIRR expression in IECs, which was dependent upon decreased SP1 binding at the responsive element of the SIGIRR promoter. We found that SIGIRR is expressed in IECs and serves as a negative regulator to maintain gut innate immunity, which is down-regulated during inflammation by inhibition of an SP1-mediated pathway.

Abstract
BACKGROUND The efficacy of rabeprazole 5 mg/day for patients with non-erosive reflux disease (NERD) has not been reported in the literature. AIM To evaluate the efficacy of rabeprazole 5 mg and 10 mg/day in Japanese NERD patients. The influence of baseline characteristics as well as genetic background on efficacy was also analysed. METHODS Subjects were grade M (minimal changes) NERD patients. Two hundred and eighty-eight of these subjects, who were nonresponders to open label antacid therapy, entered in a 4-week, double-blind treatment (placebo, rabeprazole 5 mg or 10 mg/day). RESULTS Complete heartburn relief rates were 21% in placebo, 34% in rabeprazole 5 mg and 44% in rabeprazole 10 mg (5 mg vs. placebo P = 0.074, 10 mg vs. placebo P = 0.001). Rabeprazole 5 mg was significantly more effective than placebo in elderly patients and in patients with low heartburn frequency or without hiatal hernia. The efficacy of rabeprazole 10 mg was not influenced by age, BMI, hiatal hernia, Helicobacter pylori infection, frequency and severity of heartburn or CYP2C19 genotypes. CONCLUSIONS Rabeprazole 5 mg was effective in a subgroup of Japanese NERD patients. Rabeprazole 10 mg provided more potent heartburn relief than 5 mg and was less fragile to baseline characteristics.

Abstract
This two-way crossover study investigated possible differences between the proton pump inhibitors, omeprazole and rabeprazole, in their effect on gastric acid secretion in Japanese subjects with differing cytochrome P450, family 2, subfamily C, polypeptide 19 (CYP2C19) genotypes. A total of 23 Helicobacter pylori-negative healthy volunteers received omeprazole 20 mg/day and rabeprazole 10 mg/day. Each drug treatment was given for a continuous 7-day period allocated in random order, with an interval of at least 1 week between drug treatment periods to allow for wash-out. Intragastric pH was measured on days 1 and 7. Overall median intragastric pH levels at 7 and 8 h after the first administration were significantly higher with omeprazole. There was no significant difference in intragastric pH in homozygous extensive metabolizers, whereas intragastric pH was significantly higher with omeprazole in combined data from heterozygous extensive metabolizers and poor metabolizers at 6, 7 and 8 h after the first drug administration. There were no significant differences in intragastric pH between omeprazole and rabeprazole irrespective of genotype on day 7 of administration. In conclusion, on day 1 the time to onset of the antisecretory action of 20 mg/day omeprazole was more rapid than that of 10 mg/day rabeprazole in Japanese individuals who have a higher incidence of the CYP2C19 poor metabolizer genotype, however by day 7 no difference in antisecretory effect was found, regardless of genotype.

Abstract
The stomach as a conduit after esophagectomy is preferred to the colon because it is much simpler to prepare and involves only 1 anastomosis. The following principles should be followed in preparing the stomach as an esophageal substitute: the complete removal of lymphatics within the left gastric area, and careful preservation of the gastric intramural vascular network. The line of resection, where the vessels of the left gastric area enter the gastric wall, should be cautiously decided. Border between the left and right gastric area of the lesser curvature is identified by the courses of these arteries. The 1st GIA should be inserted slightly toward the caudal side, and the 2nd GIA should be fired along the resection-line. The final GIA should be advanced to the highest point. The space beneath the sternum in the anterior mediastinum is easily created with minimal blood loss. The space is initially created by blunt finger dissection through the abdominal and cervical incisions, and further developed by insertion of a flat malleable intestinal retractor with a hole on 1 side, which is useful for elevating the esophageal substitute without a twist.

Abstract
BACKGROUND AND STUDY AIMS Unsedated transnasal small-caliber esophagogastroduodenoscopy (EGD) has been used to examine the upper gastrointestinal tract with proven feasibility and tolerability. However, a limitation of transnasal EGD is the poor lens-cleansing function of the scope due to the small-caliber water-jet nozzle. Therefore, this trial was designed to evaluate the cleansing effect of oolong tea for transnasal small-caliber EGD. PATIENTS AND METHODS Oolong tea (O), barley tea (B), and distilled water (W) were prepared as washing solutions for endoscopic lenses. Study I: after the lenses were soiled by lard oil, they were washed with one of the three washing solutions, and the image quality of photographs was judged. Study II: 982 patients who were due to undergo transnasal EGD were enrolled and randomly assigned to the O-, B-, or W-groups. The level of lens cleansing, the overall time required for endoscopy, and the volume of washing solution used were measured. RESULTS Study I: the image quality of photographs taken with lenses washed with oolong tea was significantly superior to that associated with other solutions. Study II: the level of lens cleansing in the O-group was significantly superior to that of the B- and W-groups ( P < 0.001). The volume of solution used for lens cleansing in the O-group was significantly smaller than that in the W-group ( P < 0.05). Endoscopic examination times in the O-group were shorter than those in the B- and W-groups ( P < 0.05). CONCLUSIONS In transnasal small-caliber EGD, oolong tea instead of water as a washing solution for endoscopic lens cleansing is useful to maintain good visibility.

Abstract
Several negative regulatory mechanisms control Toll-like receptor (TLR)-mediated inflammatory responses and restore immune system balance, including the zinc-finger protein A20, a negative regulator of TLR signalling that inhibits nuclear factor kappa B (NF-kappaB) activity. In the present study, we investigated TLR-5-mediated A20 expression and its role in intestinal epithelial cells (IECs) during inflammation. HCT-15 and HT-29 cells were stimulated with flagellin, then the expressions of A20, interleukin-1 receptor-associated kinase (IRAK-M) and Tollip were evaluated using RNase protection assay. Furthermore, experimental colitis was induced in tlr4-deficient CH3/HeJ mice by administration of dextran sodium sulphate (DSS), then flagellin was injected anally, and the colonic expression of A20 was examined by real-time polymerase chain reaction (PCR) and immunohistochemistry. To confirm flagellin-induced expression of A20, we employed an organ culture system. The role of A20 in flagellin-induced tolerance induction was evaluated in vitro, using a gene knock-down method targeting A20. A20 expression increased rapidly and peaked at 1 h after flagellin stimulation in cultured IECs, then declined gradually to the basal level. In vivo, anal injection of flagellin induced epithelial expression of A20 in injured colonic tissue, whereas flagellin did not cause a significant increase in A20 expression in non-injured normal tissue, which was also confirmed in vitro using the organ culture system. Gene knock-down using A20 siRNA did not influence tolerance induced by restimulation with flagellin. A20 is an early response negative regulator of TLR-5 signalling in IECs that functions during intestinal inflammation. Our results provide new insights into the negative feedback regulation of TLR-5 signalling that maintains the innate immune system in the gut.

Abstract
Color development of squid skin was controlled by O2 concentration for storage. When stored above 10% O2, the color index (CI) as an index of color development of skin increased in 24 h, and decreased gradually with further storage. The CI profile at 10% O2 was practically identical to that in air. When stored at 0.1% O2, in the presence of N2, the CI increased partly in 6 h and decreased. Morphological observation of chromatophore distinguished the CI increase at 0.1% and 10% O2 by their shape and size distribution. However, the storage of squid at O2 concentration between 2.5% and 7% practically did not change the CI for at least 48 h. ATP content of skin was kept unchanged when the storage atmosphere contained O2 concentration at 2.5% up to 48 h, while the content decreased rapidly with a half decrease in 6 h when stored at 0.1% O2. It was demonstrated clearly that ATP is regenerated in the presence of O2, but the ATP concentration did not determine the CI change during the storage. Exposure to high concentration of O2 might induce a full color development of squid skin.

Abstract
BACKGROUND AND AIMS The mechanism of transformation to intestinal metaplasia in Barrett's oesophagus has not been clarified. We previously reported that bile acids activate the Cdx2 promoter via nuclear factor kappa B (NF-kappaB) and stimulate production of Cdx2 protein in oesophageal keratinocytes with a resulting production of intestinal type mucin. In addition to Cdx2, Cdx1 may play an important role in the development of Barrett's oesophagus. Therefore, we studied the direct effects of bile acids on the expression of Cdx1 as well as the precise mechanisms of Cdx1 expression in cultured oesophageal squamous epithelial cells. Furthermore, we investigated the relationship between Cdx1 and Cdx2 expression in cultured oesophageal squamous epithelial cells. METHODS A rat model of Barrett's oesophagus was produced by anastomosing the oesophagus and jejunum. The expression of Cdx1 was investigated by immunohistochemistry, while the response of that expression to bile acids was studied using a Cdx1 promoter luciferase assay. In addition, oesophageal squamous epithelial cells were transfected with a Cdx1 or Cdx2 expression vector, after which their possible transformation to intestinal-type epithelial cells was investigated. RESULTS In our Barrett's rat model, the metaplastic epithelium and adjoining squamous epithelium strongly expressed Cdx1. Further, the bile acids mixture dose-dependently increased Cdx1 promoter activity and Cdx1 protein in oesophageal epithelial cells. Transfection of the Cdx1 expression vector in cultured oesophageal epithelial cells induced production of Cdx2 protein. CONCLUSION Bile acid-induced sequential expression of Cdx1 followed by Cdx2 may have an important role in the development of Barrett's epithelium.

Abstract
Refractory strictures of esophagogastric anastomosis caused by leakage following an esophagectomy are a severe complication, for which either repeated balloon dilations or bougies are not necessarily effective. In such a case, surgical repair is quite difficult because the esophageal substitute such as the stomach or colon is usually located in the mediastinum and severely adhesive to the neighboring organs. Furthermore, in case the resected stricture is too long for direct re-anastomosis to be performed, a free jejunal graft or a new esophageal substitute should be prepared. This paper proposes a procedure for the re-reconstruction of refractory stricture in the case of a retrosternal reconstruction with a gastric conduit, which frequently employs pull-up route. The anterior plate of the manubrium was divided medially from the notch to the symphysis with the sternal saw. The manubrium is then removed, bite by bite, like breaking up rocks, with a bone rongeur forceps, starting with the anterior plate, then the posterior plate, from upper median part to the lower and lateral part of the sternum until it reaches the symphysis and the sternoclavicular and the sternocostal joints. It is safer to destroy the manubrium little by little from the anterior side so that the posterior periosteum, which is likely to adhere tightly to the gastric conduit, can be preserved. After the manubrium is almost completely resected and the posterior periosteum of the manubrium is preserved, a median longitudinal incision is carefully made on the periosteum so as not to damage the gastric conduit that may be adhesive to the periosteum. The periosteum was gradually opened bilaterally separating the periostium and the gastric conduit. Although gastroenterological surgeons may hesitate to remove the manubrium, removing the manubrium and preserving the posterior periosteum make it possible to avoid injuring the gastric conduit and to provide a wide view around the stenosis for safely resecting the anastomotic stricture. Furthermore, this procedure allows direct re-anastomosis between the cervical esophagus and the gastric conduit without a complicated reconstruction such as a free jejunal graft. This procedure is strongly recommended as an alternative option so that a second reconstruction can be performed both safely and steadily.
