Abstract
Genotyping graft livers by short tandem repeats after human living-donor liver transplantation (n = 20) revealed the presence of recipient or chimeric genotype cases in hepatocytes (6 of 17, 35.3%), sinusoidal cells (18 of 18, 100%), cholangiocytes (15 of 17, 88.2%) and cells in the periportal areas (7 of 8, 87.5%), suggesting extrahepatic cell involvement in liver regeneration. Regarding extrahepatic origin, bone marrow mesenchymal stem cells (BM-MSCs) have been suggested to contribute to liver regeneration but compose a heterogeneous population. We focused on a more specific subpopulation (1-2% of BM-MSCs), called multilineage-differentiating stress-enduring (Muse) cells, for their ability to differentiate into liver-lineage cells and repair tissue. We generated a physical partial hepatectomy model in immunodeficient mice and injected green fluorescent protein (GFP)-labeled human BM-MSC Muse cells intravenously (n = 20). Immunohistochemistry, fluorescence in situ hybridization and species-specific polymerase chain reaction revealed that they integrated into regenerating areas and expressed liver progenitor markers during the early phase and then differentiated spontaneously into major liver components, including hepatocytes (≈74.3% of GFP-positive integrated Muse cells), cholangiocytes (≈17.7%), sinusoidal endothelial cells (≈2.0%), and Kupffer cells (≈6.0%). In contrast, the remaining cells in the BM-MSCs were not detected in the liver for up to 4 weeks. These results suggest that Muse cells are the predominant population of BM-MSCs that are capable of replacing major liver components during liver regeneration.

Abstract
We compared ultrasonography (US)-guided injection, targeting the extensor pollicis brevis (EPB) in de Quervain's disease (dQD) with septation, to clinical injection. Forty-four wrists were randomly allocated to US-guided or manual (non-US-guided) injection. At 4 weeks, pain was significantly reduced in both groups. Pain on the 100 mm visual analogue scale (VAS) for the US group was 80.3 (SD 19.6) mm at baseline and 25.6 (SD 15.1) mm at 4 weeks after injection (p = 0.004). Values for the manual group were 78.0 (SD 18.5) mm at baseline and 58.2 (SD 21.9) mm at 4 weeks after injection (p = 0.04). Pain on the VAS showed a more significant decrease in the US-guided than in the manual injection group (p = 0.0007) from baseline to 4 weeks after injection. The results of this study suggest US-guided injection targeting the EPB in dQD patients with septation is more effective than manual injection.

Abstract
OBJECTIVE There is a concept that pancreatitis results from an imbalance of proteases and their inhibitors within the pancreatic parenchyma. It has been recently shown that a loss-of-function variant, c.571G>A (p.G191R), in the anionic trypsinogen (PRSS2) gene protects against chronic pancreatitis in European populations. Here we examined the association of the p.G191R variant with pancreatic disorders in Japan. METHODS Genomic DNA was prepared from 378 healthy controls and 604 patients with pancreatic disorders (241 patients with chronic pancreatitis, 174 with acute pancreatitis, and 189 with pancreatic neoplasm). Mutational analysis of the PRSS2 gene was performed by polymerase chain reaction-restriction fragment length polymorphism and direct sequencing. RESULTS The heterozygous p.G191R variant was found in three of 241 (1.2%) patients with chronic pancreatitis, in seven of 174 (4.0%) patients with acute pancreatitis, and in 12 of 189 (6.3%) patients with pancreatic neoplasm. The p.G191R variant was found in 25 (two were homozygous and 23 were heterozygous) of 378 (6.6%) healthy controls. The p.G191R frequency in patients with chronic pancreatitis was lower than that in healthy controls (p = 0.001; odds ratio (OR) 0.178; 95% confidence interval (CI) = 0.057 to 0.561). The p.G191R frequency was lower in patients with alcoholic (0.9%; p = 0.015; OR, 0.132; 95% CI, 0.022 to 0.779) and idiopathic (1.0%; p = 0.025; OR, 0.144; 95% CI, 0.025 to 0.851) chronic pancreatitis than that in healthy controls. There were no statistical differences in the p.G191R frequency between healthy controls and patients with acute pancreatitis or with pancreatic neoplasm. Patients with alcoholic acute pancreatitis (n = 59) had no variant carrier, and the p.G191R frequency was lower than that in healthy controls (p = 0.035). CONCLUSION The p.G191R variant protected against alcoholic and idiopathic chronic pancreatitis as well as alcoholic acute pancreatitis in Japan.

Abstract
BACKGROUND AND STUDY AIM Endoscopic mucosal resection using a cap (EMR-C) is an established method for curative resection of early neoplastic lesions; prelooping of the snare may however be difficult and lead to imprecise resection. We therefore compared two modifications of the conventional technique using outer snare placement with an accessory channel in a prospective, nonrandomized study. PATIENTS AND METHODS Between October 2004 and March 2007, 54 patients (men 37, women 17; mean age 71 years) underwent EMR. One method involved an internally retained snare (IRS) cap, with a fixed prelooped snare inside the cap; the other method used an externally guided snare (EGS) cap with the snare guided over an oblique cap. The main outcome parameters were specimen size, en bloc resection, and complications. RESULTS There was no difference between use of the IRS and EGS cap methods in relation to specimen size (27.6 vs. 27.1 mm), or rates of en bloc resection (88.9 % vs. 83.3 %); only one perforation occurred, and this was in the EGS group. CONCLUSION Both techniques appeared to provide similar efficacy, the inner rim of the IRS cap stabilizes aspiration of the lesion compared with the EGS cap that does not have it.

Abstract
The technique of endoscopic submucosal dissection (ESD) needs special skills and involves a long procedure. We therefore developed a new type of dissection knife, the irrigation cap-knife (the Kume cap-knife attachment, which uses a fixed snare), that facilitates ESD by just sliding over the muscle layer with a coagulating current. The ESD procedure using the irrigation cap-knife was performed in seven patients with intramucosal gastric cancer. The tumor was separated from the surrounding normal mucosa using the insulated-tip knife. Submucosal dissection was then performed by pushing our device along the muscle layer while applying a coagulating current, at the same time as a grasping forceps, deployed through the accessory channel, was used to push the lesion away from the muscle layer. The rate of en bloc resection was 100% (7/7). The irrigating cap-knife was extremely useful for ESD of large intramucosal cancers in the stomach.

Abstract
BACKGROUND Therapy for the relief of symptoms of functional dyspepsia is unpredictable. AIM To identify which patients may benefit from antisecretory therapy. METHODS Twenty-seven patients with functional dyspepsia were selected to receive H2-receptor antagonist (H2RA) treatment for 4 weeks. Serum pepsinogen A, pepsinogen C and gastrin were measured, and Helicobacter pylori status was determined. Symptoms were assessed at baseline and after H2RA treatment. RESULTS Fourteen patients were identified as H2RA responders and the remaining patients were non-responders. No differences were found between responders and non-responders with regard to serum pepsinogen A, pepsinogen C, gastrin and H. pylori status. However, the pepsinogen A/C ratio was significantly higher in responders than in non-responders. Ten of the 13 functional dyspepsia patients (77%) with a high value of the pepsinogen A/C ratio (> or = 4.5) achieved symptom resolution by H2RA, compared with only one of the eight patients (13%) with a low value of the pepsinogen A/C ratio (< or = 3.0). CONCLUSIONS The serum pepsinogen A/C ratio seems to identify those functional dyspepsia patients for whom acid control provides benefit. This ratio may be a practical tool for the management of functional dyspepsia patients.

Abstract
The purpose of this study was to evaluate the efficacy and toxicity of weekly vinorelbine (VNB) in patients with metastatic breast cancer previously treated with both adriamycin (ADM) and docetaxel (TXT). VNB was administered weekly at the dose 20 mg/m2 by i.v. infusion over 20 minutes followed by flushing the vein with 100 ml of normal saline. From June 1999 to August 2000, ten patients were enrolled in this study. Patient characteristics were that the cumulative doses (median) of previous ADM and TXT were 300 mg (range, 120-880 mg), 560 mg (range, 120-960 mg) respectively. The median number of metastatic sites was four, with poor performance status (ECOG 1-2: 40%, 3-4: 60%). The median cycles of weekly VNB were seven (range: 2-12). Two of 10 assessable patients obtained partial response, with an overall response rate of 20%. The main toxicity (NCI grade 4) was leukopenia in 10% of 10 patients. Phlebitis (grade 2) was observed in 4 of 10 patients (40%). VNB is an active agent against metastatic breast cancer pretreated with both ADM and TXT, possessing no severe toxicities.

Abstract
BACKGROUND/AIMS Total gastrectomy has generally been performed for the treatment of early gastric cancers involving the upper third of the stomach. However, proximal gastrectomy has also been used for the treatment of cardial early gastric cancer. METHODOLOGY To compare the nutritional parameters after proximal gastrectomy with the parameters after total gastrectomy, and to also determine the advantages of the postoperative nutritional states, a retrospective analysis was made to evaluate the nutritional status of patients with early gastric cancer who underwent proximal gastrectomy with those undergoing total gastrectomy. Forty-nine patients were studied for one year after surgery; 9 underwent proximal gastrectomy while 40 had a total gastrectomy. RESULTS Proximal gastrectomy allowed the patient to better maintain both their nutritional parameters and body weight. CONCLUSIONS Proximal gastrectomy was thus found to be a beneficial modality for early gastric cancer patients regarding terms of the postoperative nutritional status, in comparison to total gastrectomy.

Abstract
The hypogastric artery is one of the major collateral arteries in aortoiliac occlusive disease. This report describes a case of limb-threatening ischemia caused by acute arterial thrombosis of the right hypogastric artery. The external iliac and distal arteries were obstructed and the hypogastric artery was a major collateral artery. A diagnostic arteriogram taken after intra-arterial thrombolytic therapy revealed a stenotic lesion in the orifice of the hypogastric artery. Open thromboendarterectomy of the hypogastric artery and patch angioplasty, using an expanded polytetrafluoroethylene graft, were performed to salvage the limb. The hypogastric artery was successfully revascularized and ischemic rest pain was relieved.

Abstract
Complete understanding of the physiology and pathology of the cartilage is essential to establish treatments for a variety of cartilage disorders and defects such as rheumatoid arthritis, congenital malformations, and tumors of cartilage. Although synthetic materials have been used in many cases, they possess inherent problems including wear of the materials and low mechanical strength. Autograft has been considered very effective to overcome these problems. However, the limitation of the transplant volume is a major problem in autograft to be overcome. The costal cartilage is the most serious candidate for donor site transplantation, since it is the largest permanent hyaline cartilage in the body. To investigate the possibility using the costal cartilage as a transplant source, we have established and characterized three mouse chondrocyte cell lines (MCC-2, MCC-5, and MCC-35) derived from the costal cartilage of 8-week-old male SV40 large T-antigen transgenic mice. At confluence, all the cell lines formed nodules that could be positively stained with alcian blue (pH 2.5). The size of nodules gradually increased during culturing time. After 2 and 6 weeks of culture, RT-PCR analysis demonstrated that all three cell lines expressed mRNA from the cartilage-specific genes for type II collagen, type XI collagen, aggrecan, and link protein. Furthermore, type X collagen expression was detected in MCC-5 and MCC-35 but not in MCC-2. Any phenotypic changes were not observed over 31 cell divisions. Immunocytochemistry showed further that MCC-2, MCC-5, and MCC-35 produced cartilage-specific proteins type II collagen and type XI collagen, while in addition MCC-5 and MCC-35 produced type X collagen. Treatment with 1alpha, 25-dihydroxyvitamin D(3) inhibited cell proliferation and differentiation of the three cell lines in a dose-dependent manner. These phenotypic characteristics have been found consistent with chondrocyte cell lines established from cartilage tissues other than costal cartilage. In conclusion, costal cartilage shows phenotypic similarities to other cartilages, i.e., articular cartilage and embryonic limbs, suggesting that costal cartilage may be very useful as the donor transplantation site for the treatment of cartilage disorders. Furthermore, the cell lines established in this study are also beneficial in basic research of cartilage physiology and pathology.
