Glycogen storage disease type Ia (GSD-Ia; also called von Gierke disease) is an autosomal recessive disorder of carbohydrate metabolism caused by glucose-6-phosphatase deficiency. There have been many reports describing hepatic tumors in GSD patients; however, most of these reports were of hepatocellular adenomas, whereas there are only few reports describing focal nodular hyperplasia (FNH) or hepatocellular carcinoma (HCC). We report a case with GSD-Ia who had undergone a partial resection of the liver for FNH at 18 years of age and in whom moderately differentiated HCC had developed. Preoperative imaging studies, including ultrasonography, dynamic computer tomography (CT) and magnetic resonance imaging, revealed benign and malignant features. In particular, fluorodeoxyglucose-positron emission tomography (FDG-PET)/CT revealed the atypical findings that FDG accumulated at high levels in the non-tumorous hepatic parenchyma and low levels in the tumor. Right hemihepatectomy was performed. During the perioperative period, high-dose glucose and sodium bicarbonate were administered to control metabolic acidosis. He had multiple recurrences of HCC at 10 mo after surgery and was followed-up with transcatheter arterial chemoembolization. The tumor was already highly advanced when it was found by chance; therefore, a careful follow-up should be mandatory for GSD-I patients as they are at a high risk for HCC, similar to hepatitis patients.

＜正＞The amyloid β-protein （Aβ） 42 plays a pivotal role in Alzheimer disease （AD）. We have previously reported that intracellular Aβ42 is associated with neuronal apoptosis （Chui et al, 1999, Chui et al, 2001）. AD may be caused by toxic aggregates formed from Aβpeptides. By using Thioflavin T, a dye that specifically binds to β-sheet structures, we found that highly toxic forms of Aβaggregates were formed at

Aim: The short-term perioperative results of laparoscopic treatment of gallbladder (GB) carcinoma were evaluated to determine whether this technique can be a feasible treatment option. Methods: Ten patients with fundus/body GB tumors (GBTs) underwent laparoscopic liver resection (LLR) and lymph node dissection. Additionally, 124 patients underwent LLR for liver tumors. These 124 LLRs included 79 partial resections (PRs), 11 left lateral sectionectomies (LLSs), 25 anatomical resections (ARs), and 9 small ARs (SARs). The operation time (OT), intraoperative blood loss (BL), and postoperative length of hospital stay (LOS) were compared between the GBT and various LLR groups. Results: The median (range) OT in the GBT, PR, LLS, AR, and SAR groups was 298 (186-488), 245 (84-700), 328 (150-682), 458 (224-848), and 352 (274-696) min, respectively. The BL was 109 (10-500), 50 (0/uncountable-3,270), 100 (10-516), 375 (25-3,569), and 705 (35-1,920) mL, respectively. The LOS was 16 (8-105), 15 (5-254), 13 (11-52), 22 (8-44), and 15 (8-44) days, respectively. The OT and BL were significantly different between the GBT and AR groups. Conclusion:Laparoscopic surgery could be a good treatment option for GBTs suspected to be T1b/T2 GB carcinoma in the GB body/fundus without cystic duct invasion.

AIM: To evaluate the efficacy of technical modifications of total hepatic vascular exclusion(THVE) for hepatectomy involving inferior vena cava(IVC).METHODS: Of 301 patients who underwent hepatectomy during the immediate previous 5-year period, 8(2.7%) required THVE or modified methods of IVC cross-clamping for resection of liver tumors with massive involvement of the IVC. Seven of the patients had diagnosis of colorectal liver metastases and 1 had diagnosis of hepatocellular carcinoma. All tumors involved the IVC, and THVE was unavoidable for combined resection of the IVC in all 8 of the patients. Technical modifications of THVE were applied to minimize the extent and duration of vascular occlusion, thereby reducing the risk of ***: Broad dissection of the space behind the IVC coupled with lifting up of the liver from the retrocaval space was effective for controlling bleeding around the IVC before and during THVE. The procedures facilitate modification of the positioning of the cranial IVC cross-clamp. Switching the cranial IVC cross-clamp from supra- to retrohepatic IVC or to the confluence of hepatic vein decreased duration of the THVE while restoring hepatic blood flow or systemic circulation via the IVC. Oblique cranial IVC cross-clamping avoided ischemia of the remnant hemi-liver. With these technicalmodifications, the mean duration of THVE was 13.4 ± 8.4 min, which was extremely shorter than that previously reported in the literature. Recovery of liver function was smooth and uneventful for all 8 patients. There was no case of mortality, re-operation, or severe complication(i.e., Clavien-Dindo grade of Ⅲ or more).CONCLUSION: The retrocaval liver lifting maneuver and modifications of cranial cross-clamping were useful for minimizing duration of THVE.

Among the various diagnostic modalities for small bowel hemangioma, video capsule endoscopy (VCE) and double-balloon enteroscopy (DBE) can be recommended as part of the work-up in patients with obscure gastrointestinal bleeding (OGIB). DBE is superior to VCE in the accuracy of diagnosis and therapeutic potential, while in most cases total enteroscopy cannot be achieved through only the antegrade or retrograde DBE procedures. As treatment for small bowel bleeding, especially spout bleeding, localization of the lesion for the decision of DBE insertion facilitates early treatment, such as endoscopic hemostatic clipping, allowing patients to avoid useless transfusion and the worsening of their disease into life-threatening status. Applying endoscopic India ink marking prior to laparoscopic surgical resection is a particularly useful technique for more minimally invasive treatment. We report two cases of small bowel hemangioma found in examinations for OGIB that were treated with combination of laparoscopic and endoscopic modalities.

AIM To investigate the relationship between plasma ghrelin level, Helicobacter pylori(H. pylori) infection status and the severity of atrophy in hemodialysis *** One hundred eights patients who received hemodialysis and 13 non-hemodialysis H. pylori-negative controlsunderwent gastroduodenoscopy to evaluate the severity of gastric atrophy. Serum levels of pepsinogen(PG) were measured as serum markers of gastric atrophy. H. pylori infection was evaluated by anti-H. pylori IgG antibody, rapid urease test and culture test. We classified H. pylori infection status as non-infection, present infection and past infection. In addition, plasma acyl-ghrelin and desacyl-ghrelin levels were measured by enzyme-linked immunosorbent assay. RESULTS Infection rate of H. pylori was 45.4%(49/108). Acylghrelin level in the non-infection group(39.4 ± 23.0 fmol/ml) was significantly higher than in the past(23.4 ± 19.9 fmol/ml, P = 0.005) and present infection groups(19.5 ± 14.0 fmol/ml, P < 0.001). Furthermore, desacyl-ghrelin level in the non-infection group(353.2 ± 190.2 fmol/ml) was significantly higher than those in the past(234.9 ± 137.5 fmol/ml, P = 0.008) and present infection groups(211.8 ± 124.2 fmol/ml, P < 0.001). Acyl-ghrelin was positively correlated with the PG Ⅰ level and PG Ⅰ/Ⅱ ratio(|R| = 0.484, P < 0.001 and |R| = 0.403, P < 0.001, respectively). Both ghrelins were significantly decreased in accordance with the progress of endoscopic atrophy(both P < 0.001) and acyl-ghrelin was significantly lower in patients with mild, moderate and severe atrophy(24.5 ± 23.1 fmol/ml, 20.2 ± 14.9 fmol/ml and 18.3 ± 11.8 fmol/ml) than in those with non-atrophy(39.4 ± 22.2 fmol/ml, P = 0.039, P = 0.002 and P < 0.001, respectively).CONCLUSION In hemodialysis patients, plasma ghrelin level was associated with the endoscopic and serological severity of atrophy related to H. pylori infection.

Genetic mechanisms have been implicated as a cause of some cases of male infertility. Recently, 10 novel genes involved in human spermatogenesis were identified by microarray analysis of human testicular tissue. One of these is spermatogenesis-associated 17 （SPATA17）. To investigate whether defects in the SPATA17 gene are associated with azoospermia due to meiotic arrest, a mutational analysis was conducted, in which the SPATA17 coding regions of 18 Japanese patients with this condition were sequenced. A statistical analysis was carried out that included 18 patients with meiotic arrest, 20 patients with Sertoli-cell-only syndrome （SCOS） and 96 healthy control men. No mutations were found in SPA TA17. However, three coding single nucleotide polymorphisms （cSNPs： SNP 1-SNP3） were detected in the patients with meiotic arrest. No significant differences in the genotype or allele frequencies of SNP1 and SNP2 were found between patients with meiotic arrest and the others. However, the frequency of the SNP3 allele was significantly elevated in the meiotic arrest group （P 〈 0.05）. This study suggests that SPATA17 may play a critical role in human spermatogenesis, especially in meiosis.
