Abstract
We report five patients with atypical parkinsonism characterized by freezing phenomenon, akinesia and axial rigidity without limb rigidity or tremor. These patients were selected from 252 patients with parkinsonism who were referred to our clinic from 1986 to 1993. They have common clinical features consisting of freezing phenomena involving all four extremities, especially in the initiation of walking, and marked axial rigidity; otherwise, neither supranuclear ophthalmoparesis nor nuchal dystonia was noted. Their clinical features did not change over several years except in one patient who later developed typical manifestations of progressive supranuclear palsy (PSP). Levodopa was of no effect on their symptoms. After excluding other possibilities, it is our conclusion that they represent an atypical form of PSP lying between the pure akinesia of Imai and Narabayashi and the typical form of PSP.

Abstract
Proteus syndrome is a rare congenital hamartomatous condition that is characterised by a wide range of malformations. Skin and skeletal developmental malformations are common and may manifest as significant physical anomalies. However, few reports have discussed surgical treatment. A 37-year-old woman presented with disproportionate enlargement of the right buttock, which required volume reduction. The overgrown tissue was combined with vascular malformations, which in our patient were extremely thick. The patient experienced massive blood loss during the procedure, due to which a blood transfusion was performed. Pathological findings revealed partial lipohyperplasia with venous malformations. Thus, during operations including incomplete excision, massive bleeding is always a possibility, but is not commonly described in these instances.

Abstract
Memory T cells survive for many months and years and are critically important for host defence in humans. In tumour immunity, they have been also suggested to play a significant role in tumour progression and metastasis. However, the role of memory T cells in actual human cancer remains largely unknown. In this study, the clinical importance of tumour-infiltrating CD45RO(+) memory T cells was investigated in human oesophageal squamous cell carcinoma (OSCC). CD45RO(+) T cells were evaluated by immunohistochemistry in primary OSCC tumours from 105 patients. Patients were classified into two groups as CD45RO(+hi) or CD45RO(+lo) based on the number of cells stained positively for CD45RO. No significant difference was observed between CD45RO status and several clinicopathological prognostic factors. However, the postoperative overall and disease-free survival for CD45RO(+hi) patients was significantly better than for CD45RO(+lo) patients. Furthermore, there were significant correlations of CD45RO status in the primary tumour with postoperative lymph node and pulmonary recurrence, suggesting that memory T cells may control postoperative metastatic recurrence. Most importantly, CD45RO(+) memory T cell status has a significant prognostic value for OSCC independently of conventional tumour-node-metastasis (TNM) classification. Our study may provide a rationale for developing a novel immunotherapy in intentional induction of memory T cells for the treatment of oesophageal cancer.

Abstract
Intrauterine infection and inflammation are recognized as major contributors to the onset of preterm labor. We describe two cases of severe preterm labor with bulging membrane that were treated by intravenous injection of Sivelestat, a neutrophil elastase inhibitor. Ritodrine hydrochloride and magnesium sulfate were intravenously administered for tocolysis, and ampicillin was provided as an antibiotic. Urinary trypsin inhibitor (UTI) was administered transvaginally. Sivelestat was infused intravenously at 4.8 mg kg(-1) day(-1) through the maternal vein. No side effects were observed. Levels of interleukin (IL)-6 and IL-8 in amniotic fluid decreased, and gestations were prolonged without complications for >1 week. Two healthy infants were delivered. Our experience suggests that multidrug therapy with Sivelestat offers a new therapeutic strategy for preterm labor, but further investigations of the indications, administration period and dosage are required.

Abstract
The Daya Bay Reactor Neutrino Experiment has measured a nonzero value for the neutrino mixing angle θ(13) with a significance of 5.2 standard deviations. Antineutrinos from six 2.9 GWth reactors were detected in six antineutrino detectors deployed in two near (flux-weighted baseline 470 m and 576 m) and one far (1648 m) underground experimental halls. With a 43,000 ton-GWth-day live-time exposure in 55 days, 10,416 (80,376) electron-antineutrino candidates were detected at the far hall (near halls). The ratio of the observed to expected number of antineutrinos at the far hall is R=0.940±0.011(stat.)±0.004(syst.). A rate-only analysis finds sin(2)2θ(13)=0.092±0.016(stat.)±0.005(syst.) in a three-neutrino framework.

Abstract
PURPOSE Transcatheter angiographic embolization (TAE) has been widely accepted as a treatment for hemorrhagic shock associated with pelvic fracture. Gluteal muscle necrosis is a rare but potentially fatal complication of TAE. This study aimed to clarify factors associated with safer embolization procedures by evaluating relationships between embolic site and risk of gluteal skin injury. METHODS We classified embolized arteries into six groups: group A, nonselective embolization from the main internal iliac artery; group B, selective embolization including the superior gluteal artery but excluding the inferior gluteal artery; group C, selective embolization including the inferior gluteal artery but excluding the superior gluteal artery; group D, selective embolization including both the superior and inferior gluteal arteries; group E, selective embolization excluding both the superior and inferior gluteal arteries; and group F, no embolization. We assessed the frequency of gluteal injuries, relationships between gluteal injuries and embolized arteries, and the contributions of selective embolization, conservation of the superior or inferior gluteal artery, and conservation of both the superior and inferior gluteal arteries to reducing the risk of gluteal injury. RESULTS Gluteal skin injuries were seen at 15 of 160 sites (9.4%). A significant difference was noted between the nonselective embolization group (group A: 10/82, 12.2%) and selective embolization excluding both the superior and inferior gluteal arteries (group E: 1/39, 2.6%) (p = 0.042). CONCLUSIONS If possible, we recommend selective embolization avoiding the superior and inferior gluteal arteries.

Abstract
A major complication of diabetes mellitus is the disruption of normal wound repair process, characterised by insufficient production of growth factors. A molecular genetic approach wherein resident cells synthesise and deliver the growth factors to the wound site would be a powerful therapeutic strategy to treat diabetic wounds. One such molecular approach could be the application of microRNAs (miRNAs). This study reports differential expression of miRNAs related to cell development and differentiation, during wound healing in diabetic mice. Comparison of skin tissue from normal and diabetic mice showed that 14 miRNAs were differentially expressed in diabetic skin; miR-146b and miR-21 were the most noteworthy. Expression pattern of these miRNAs was also altered during healing of diabetic wounds. A subset of miRNAs (miR-20b, miR-10a, miR-10b, miR-96, miR-128, miR-452 and miR-541) exhibited similar basal levels in normal and diabetic skins, but displayed dysregulation during healing of diabetic wounds. Amongst the miRNAs studied, miR-21 showed a distinct signature with increased expression in diabetic skin but decreased expression during diabetic wound healing. We analysed the role of miR-21 in fibroblast migration, because migration of fibroblasts into the wound area is an important landmark facilitating secretion of growth factors and migration of other cell types into the wound, thus enhancing the healing process. Using gain-of and loss-of function approaches, we show that miR-21 is involved in fibroblast migration. Our preliminary studies implicate an important role for miRNAs in the pathogenesis of diabetic wounds.

Abstract
Background: Memory T cells are well known to have a critical role for host defense in humans. However, their role in actual human cancer remains largely unknown. In this study, we tried to reveal the clinical importance of tumour-infiltrating CD45RO+ memory T cells in renal cell carcinoma (RCC). Methods: We analysed 105 patients with RCC, who received radical or partial nephrectomy. Those were 65 in TNM stage I, 7 in stage II, 15 in stage III, and 18 in stage IV, respectively. CD45RO expression was evaluated by immunohistochemistry. CD4 and CD8 expressions were also systematically assessed in the same manner. Results: Patients with higher TNM stage or high nuclear grade were found to have higher densities of CD45RO. Furthermore, CD45RO status was positively correlated with preoperative C-reactive protein level. In prognostic analysis, CD45RO+lo patients had a significantly better prognosis than CD45RO+hi patients. There was also a significant difference between CD4+lo and CD4+hi groups, whereas no significant difference was observed in CD8 T-cell status. Finally, multivariate analysis revealed that CD45RO+ status was the independent prognostic factor for patient overall survival. Conclusion: CD45RO+ memory T-cell status has a significant independent prognostic value, indicating that the adaptive immune response is functionally critical in human RCC.

Abstract
Surgery and radiation therapy have been used to treat esophageal squamous cell carcinoma. However, treatment outcomes have not yet been extensively investigated. The aim of this study was to compare surgery and radiation therapy for clinical T1 esophageal squamous cell carcinoma. A total of 67 clinical T1 esophageal squamous cell carcinoma patients were treated between January 1997 and December 2005; 29 had undergone radical esophagectomy (surgery group) and 38 were treated with definitive radiation therapy (radiation group). The mean patient age was lower in the surgery group than in the radiation group. In surgery group, respiratory complications, anastomotic leaks, recurrent nerve palsies, and anastomotic stenosis occurred in 7, 8, 6, and 5 patients, respectively. In radiation group, leucopenia, esophagitis, pericarditis were observed in 15, 3, and 3 patients, respectively. The 5-year overall survival rate for the surgery group was 68.9%, and 74.3% for the radiation group. There were no significant difference between groups (P= 0.3780). The 5-year relapse-free survival rate in the surgery group was 61.8% and 38.8% in the radiation group. The relapse-free survival rate was significantly higher in the surgery group than in the radiation group (P= 0.0051). The 5-year overall and relapse-free survival rates for tumors invaded into but not through the muscularis mucosa were 83.3% and 75.0%, respectively, in the surgery group and 78.8% and 33.3%, respectively, in the radiation group. There were no significant differences. The 5-year overall survival rates for patients with tumors that invaded the submucosal layer was 64.9% in the surgery group and 66.5% in the radiation group. This difference was not significant (P= 0.8712). The 5-year relapse-free survival rate in the surgery group (56.0%) was significantly higher than that in the radiation group (41.8%; P= 0.0219). In conclusion, surgery may become a standard treatment for cT1 esophageal cancer that can offer longer relapse-free survival, particularly for patients with tumors that invade the submucosa.

Abstract
We present a case of a 14-year-old male with incessant idiopathic ventricular tachycardia for which both pharmacological and catheter ablation treatments failed. Curative surgery was performed on this patient. By intraoperative epicardial isochronous mapping, arrhythmogenic focus was identified in the right ventricular infundibulum between the large conus branch and the proximal right ventricular coronary branch. After cryoablation both from the epi- and endo-cardial sides failed to terminate the arrhythmia, subsequent full-thickness resection of the identified focus was performed. There was no postoperative recurrence of tachyarrhythmia In idiopathic ventricular tachycardia, arrhythmogenic focus is not always situated on the endo- or epicardial side. Full-thickness resection of the focus site might be necessary in such patients as we experienced this time.

Abstract
307 Background: Unresectable pancreatic cancer is poorly responsive to conventional therapies. We conducted a phase I/II study to ascertain the recommended dose (RD) of 5-fluorouracil (5-FU) in arterial infusion chemotherapy combined with systemic gemcitabine in unresectable pancreatic cancer and to evaluate the safety and efficacy. Methods: 5-FU was administered through the pancreatic and hepatic arteries via the port system as a 5-hour infusion on days 1, 8, and 15 every 4 weeks for 5 cycles. Gemcitabine was administered in 30-minute intravenous infusion at the same days. In phase I, escalating 5-FU doses for level 1 and 2 was set at 750mg and 1,000mg/m2, respectively. Dose of coadministered gemcitabine (1,000 mg/m2) was fixed. Using a 3+3 study design, dose-limiting toxicity (DLT) was assessed, and RD was estimated in the first cycle. In phase II, more RD patients were added to assess tumor response, toxicity, overall survival and progression-free survival. Results: During the phase I, 7 patients were enrolled. DLT was not observed. One patient dropped out of this study because of insufficient drug distribution via the port system. Assuming RD at 1,000mg/m2 of 5-FU, the phase II enrolled a total of 16 patients (metastatic, 14; local advanced, 2). The tumor response rate was 68.8% (CR 0, PR 11, SD 2, PD 3). The grade 3 toxicities of neutropenia (6%) and thrombocytopenia (6%) were observed. Median overall and progression-survival times (all patients) were 9.8 and 6.2 months, respectively. Conclusions: Arterial infusion 5-FU 1,000mg/m2 combined with full-dose systemic gemcitabine was tolerable and can produce a high response rate with encouraging survival duration for unresectable pancreatic cancer.
