Background: Pain in patients with orthopedic problems is an important aspect of surgical evaluation. However, the effect on the quality of life depends not only on the degree of pain but also on its type. Hip arthroscopy has been performed for hip joint symptoms caused by femoroacetabular impingement (FAI) and hip labrum tears. However, the degree and type of pain after hip arthroscopy remains unknown. Objective: This study aimed to clarify the degree and type of pain during 6 months after hip arthroscopy. Methods: Non-athlete patients aged 20 - 65 years who underwent hip arthroscopy between December 2018 and October 2019 participated in a questionnaire survey before hospitalization and at 1, 3, and 6 months after surgery. The questionnaire comprised the Japanese Orthopaedic Association Hip-Disease Evaluation Questionnaire (JHEQ) for quality of life, International Physical Activity Questionnaire (IPAQ) for activities, and the Short-Form McGill Pain Questionnaire (SF-MPQ-2) for pain. Results: The analysis included 10 patients (men: 4, women: 6, mean age: 38 ± 8.6 years, FAI: 6 cases, hip labrum tears: 4 cases). The average time from symptom onset to surgery was 26.9 ± 19.0 months. The analysis from before surgery to 6 months after surgery showed improvement over time in all scale scores (JHEQ, IPAQ, and SF-MPQ-2). The degree of pain was significantly improved based on the JHEQ visual analog scale evaluation (P = 0.019) 3 months after surgery. Significant improvement in intermittent pain (P = 0.011) based on SF-MPQ-2 was noted 3 months after surgery;however, no significant improvement in continuous pain was noted. Conclusions: Patients who underwent hip arthroscopy showed significant improvements in the degree of pain and type of intermittent pain from before surgery to 3 months after surgery, however, no change was observed in continuous pain.

AIM： To discuss the efficacy of endoscopic mass screening for gastric cancer.METHODS： The data used in this study were the results of mass screening programs for gastric cancer in Niigata City from 2002 to 2004. The number of participants was 35089 in 2002, 34557 in 2003 and 36600 in 2004. The finding ratio referred to the final diagnosis of gastric cancer after a double check of endoscopic files and histological findings. The costs of identifying one case of gastric cancer were calculated based on the total expense for each screening program and additional close examinations. RESULTS： From the analysis of individual screening program with endoscopy, individual screening program with X-ray （ISX） and mass screening program with photofluorography （MSP） in reference to the finding ratio of gastric cancer, endoscopic examination was the best for detecting early gastric cancer, the finding ratio was 0.87% in 2004, approximately 2.7 and 4.6 times higher than those of the ISX and MSP groups. In addition, this novel method was the cheapest means regarding the cost of identifying one case of gastric cancer, which was estimated to be 1608000 Japanese yen in 2004. CONCLUSION： Endoscopic mass screening is a promising method and can be effectively applied if a sufficient number of skilled endoscopists become available to staff the system and if city offices support it.

Melatonin (MEL) has been reported to have acute enhancing effects on some aspects of cognition. Recently, we revealed that N1-acetyl-5-methoxyquinuramine (AMK), a brain metabolite of MEL, is much more potent than MEL in converting short-term memory (STM) to long-term memory (LTM) with a single administration immediately after the acquisition trial of the novel object recognition (NOR) task. These data suggest that the memory-enhancing effects of MEL may be mediated by mechanisms independent of the activation of MEL MT1 and MT2 receptors. In the present study, we examined the contribution of MT1 and MT2 receptor-mediated and non-receptor-mediated mechanisms to the acute memory-enhancing effects of MEL using NOR task. Mice were administered with either MEL, AMK, or a highly selective MT1/MT2 receptor agonist ramelteon (RAM) immediately after the acquisition trial and the effects of varying doses of these drugs on both STM and LTM performance were compared. We found that both AMK and RAM were more potent than MEL in both facilitating STM and promoting LTM formation. We also found that pretreatment with luzindole, a MT1/MT2 receptor antagonist, markedly suppressed only the effects of RAM. These results suggest that acutely administered MEL enhances NOR memory through both MT1 and MT2 receptor-mediated and non-receptor-mediated mechanisms.

AIM： To clarify the clinicopathological characteristics of small and large early invasive colorectal cancers （EI-CRCs）, and to determine whether malignancy grade depends on size. METHODS： A total of 583 consecutive EI-CRCs treated by endoscopic mucosal resection or surgery at the National Cancer Center Hospital between 1980 and 2004 were enrolled in this study. Lesions were classified into two groups based on size： small （≤10 ram） and large （〉10 ram）. Clinicopathological features, incidence of lymph node metastasis （LNM） and risk factors for LNM, such as depth of invasion, lymphovascular invasion （LVI） and poorly differentiated adenocarcinoma （PDA） were analyzed in all resected specimens. RESULTS： There were 120 （21%） small and 463 （79%） large lesions. Histopathological analysis of the small lesion group revealed submucosal deep cancer （sin： 1〉1000 μm） in 90 （75%） cases, LVI in 26 （22%） cases, and PDA in 12 （10%） cases. Similarly, the large lesion group exhibited submucosal deep cancer in 380 （82%） cases, LVI in 125 （27%） cases, and PDA in 79 （17%） cases. The rate of LNM was 11.2% and 12.1% in the small and large lesion groups, ***： Small EI-CRC demonstrated the same aggressiveness and malignant potential as large cancer.

Subtropical “Yambaru” forest, situated in the northern part of Okinawa Island of Japan, has a precious ecosystem inhabited by many endemic species. However, this region is also the center for forestry on Okinawa. Therefore, sustainable forestry activities should take into consideration the natural environment. To contribute to sustainable forest management in the region, we conducted prediction of the site index at fine-scale resolution by using multiple regression analysis with easily calculated topographic factors. For the multiple regression analysis with site index as a dependent variable, three topographic factors (the effective relief, openness, and elevation) were adopted as independent variables. Approximately 68% of the variance was explained, and the effective relief was the variable with the greatest influence. This means that it is possible to predict forest productivity at a finer scale of resolution than ever before. For sustainable forest management of sites where environmental conservation and forestry are conflicting, it is useful to estimate the site index at the finest scale of resolution practically available in the field. It might be possible to improve estimation accuracy by examining further environmental factors in the future.

A new high repetition rate Nd：YAG Thomson scattering system is developed for the Heliotron J helical device. A main purpose of installing the new system is the temporal evolution measurement of a plasma profile for improved confinement physics such as the edge transport barrier （H-mode） or the internal transport barrier of the helical plasma. The system has 25 spatial points with -10 mm resolution. Two high repetition Nd：YAG lasers （〉 550 m J@ 50 Hz） realize the measurement of the time evolution of the plasma profile with ~10 ms time intervals. Scattered light is collected by a large concave mirror （D----800 mm, f/2.25） with a solid angle of -100 mstr and transferred to interference filter polychromators by optical fiber bundles in a staircase form. The signal is amplified by newly designed fast preamplifiers with DC and AC output, which reduces the low frequency background noise. The signals are digitized with a multi-event QDC, fast gated integrators. The data acquisition is performed by a VME-based system operated by the CINOS.
