Coping with Too Many Variants: A New Type of Edition of the Scripture of the Pure Divinities' Netted [Banners] (Fanwang jing)

FUNAYAMA Toru 동국대학교 불교학술원 2017 International Journal of Buddhist Thought & Cultur Vol.27 No.2

The Chinese Buddhist scripture Fanwang jing (FWJ) or the Scripture of the Pure Divinities’ Netted [Banners] (T 24, no. 1484) exerted enormous influence on the formation and evolution of the idea of bodhisattva precepts in East Asian Buddhism. A careful comparison of early manuscript and woodblock editions reveals that the FWJ was reformed again and again over the centuries. A large number of variants in the FWJ are also worthy of attention. The second roll of the FWJ, seven pages long in the Taishō edition, has over 300 locations for which variant readings exist. I have attempted to make a list of earlier manuscript and woodblock editions of the FWJ; to explain the fundamental differences between the two—old and new—lineages of the text; and to present problems posed by both the Western-style “critical edition” and the “East Asian traditional edition.” As an example of the appropriate method for editing a text rich in variants, I proposed a new type of edition for the FWJ by selecting turning points in the text’s history, upon which basis I present the following data: a presumed original or earliest form with a critical apparatus #1; a manuscript version of its early succession #2; a version dating to the beginnings of later transformations #3 and #4, and the three canonical versions as representative of currently popular editions #5, #6, and #7. By presenting three samples, I explained a possible style for a new type of edition appropriate for simultaneously describing both the original form and later transformations of the FWJ. In accordance with this methodology I have published a monograph as Funayama (2017).

Background: Mandibular reconstruction is performed after segmental mandibulectomy, and precise repositioning of the condylar head in the temporomandibular fossa is essential for maintaining preoperative occlusion. Methods: In cases without involvement of soft tissue around the mandibular bone, the autopolymer resin in a soft state is pressed against the lower border of the mandible and buccal and lingual sides of the 3D model on the excised side. After hardening, it is shaved with a carbide bar to make the proximal and distal parts parallel to the resected surface in order to determine the direction of mandibular resection. On the other hand, in cases that require resection of soft tissue around the mandible such as cases of a malignant tumor, right and left mandibular rami of the 3D model are connected with the autopolymer resin to keep the preoperative position between proximal and distal segments before surgical simulation. The device is made to fit the lower border of the anterior mandible and the posterior border of the mandibular ramus. The device has a U-shaped handle so that adaptation of the device will not interfere with the soft tissue to be removed and has holes to be fixed on the mandible with screws. Results: We successfully performed the planned accurate segmental mandibulectomy and the precise repositioning of the condylar head by the device. Conclusions: The present technique and device that we developed proved to be simple and useful for restoring the preoperative condylar head positioning in the temporomandibular fossa and the precise resection of the mandible.

Vertical distraction osteogenesis of a reconstructed mandible with a free vascularized fibula flap: a report of two cases

Saito, Naoaki,Funayama, Akinori,Arai, Yoshiaki,Suda, Daisuke,Takata, Yoshiyuki,Kobayashi, Tadaharu Korean Association of Maxillofacial Plastic and Re 2018 Maxillofacial Plastic Reconstructive Surgery Vol.40 No.-

Background: The free vascularized fibula flap presents many advantages such as sufficient length of the bony segment, good vascularization, better quality of the bone, and a long vascular pedicle, but it is also associated with some disadvantages with regard to prosthetic rehabilitation because of its limited height. Improvement in bone height is necessary for ideal dental implant treatment of reconstructed mandibles. Case presentation: For two squamous cell carcinoma patients, mandibular bone reconstruction was performed secondarily with the peroneal flap after tumor resection. Since the bone height was insufficient at the time of implant treatment, occlusion reconstruction by dental implant was performed after vertical distraction osteogenesis. Conclusions: Vertical distraction osteogenesis is a suitable treatment option for alveolar ridge deficiency resulting from fibula transplantation for mandibular reconstruction following tumor surgery.

Purpose: The development of assistive devices has allowed for the performance of capsule endoscopy in children. Anticipating the capsule’s transit time could affect the efficacy of the investigation and potentially minimize the fasting period. This study determined the predictors of small bowel transit time for small-bowel capsule endoscopy in children and adolescents with inflammatory bowel disease. Methods: We retrospectively examined children and adolescents with inflammatory bowel disease who underwent capsule endoscopy by the age 18 at a Japanese tertiary care children’s hospital. Small bowel transit time predictors were analyzed using multiple regression with explanatory variables. Results: Overall, 92 patients, aged 1–17 years, with inflammatory bowel disease (63 Crohn’s disease and 29 ulcerative colitis cases) were examined for factors affecting small bowel transit time. In the simple regression analysis, diagnosis, age, height, weight, serum albumin, general anesthesia, and small intestine lesions were significantly associated with small bowel transit time. In the multiple regression analyses, serum albumin (partial regression coefficient: −58.9, p=0.008), general anesthesia (partial regression coefficient: 127, p<0.001), and small intestine lesions (partial regression coefficient: 30.1, p=0.037) showed significant associations with small bowel transit time. Conclusion: Hypoalbuminemia, the use of general anesthesia for endoscopic delivery of the capsule, and small intestine lesions appeared to be predictors of prolonged small bowel transit time in children and adolescents with inflammatory bowel disease. Expecting the finishing time may improve examination with a fasting period reduction, which benefits both patients and caregivers.

A microstructure of unidirectional porous hydroxyapatite (UDPHAp) has a diameter of 100-300 μm, which pene-trates through the material. In addition, it has a porosity of 75% and initial compression strength of approximately 14 MPa. The objective of the present study was to investigate the feasibility of UDPHAp for the tibial wedge osteot-omy in canines. We performed the operation on the right tibia of the dogs, and a wedge-shaped UDPHAp was implanted in the gap after the osteotomy. At 6 and 12 weeks after the operation, the specimens were solid and bony union could be macroscopically observed. Radiological examination revealed that complete consolidation between the osteotomy site and the UDPHAp was established at 12 weeks. Histological evaluation revealed fibrous tissues between the host bone and the UDPHAp at 6 weeks, although new bone formation was observed at the edges of the material. At 12 weeks, direct bonding and bone ingrowth was observed. This study indicates that UDPHAp has great potential for use as a bone substitute for open-wedge high tibail osteotomy in clinical condition.

Study Design: Prospective experimental study in humans.Purpose: To determine whether the hybrid assistive limb (HAL) for Care Support can reduce lumbar load during a patient transfer.Overview of Literature: The prevalence of work-related low back pain (LBP) among nurses is high. In particular, transferring patients poses a high risk for LBP due to the large lumbar load. Attempts to reduce the lumbar load are crucial to avoid the risk of LBP. Therefore, we investigated the effects of the HAL for Care Support.Methods: Nineteen volunteers (16 men, three women) lifted a 60-kg doll from a seated position to a standing position. The first transfer was performed without the HAL for Care Support, and the second was performed with the HAL for Care Support assistive robot. We evaluated transfer performance, the visual analog scale (VAS) score for lumbar fatigue, and electromyogram analyses of the trunk and hip.Results: Four participants (two men, two women) succeeded with the HAL for Care Support even though they were unable to perform the task without it. The mean lumbar fatigue VAS score for all participants without the HAL for Care Support was 62 mm, while that with it was 43 mm. With lumbar assistance from the HAL for Care Support, subjective lumbar fatigue during the transfer decreased significantly. A power analysis indicated adequate statistical power to detect a difference in the VAS score for lumbar fatigue (0.99). The activity of the left gluteus maximus alone increased significantly during transfers with the HAL for Care Support. No adverse events occurred during use of the HAL for Care Support for transfers.Conclusions: The HAL for Care Support was able to reduce lumbar load in a simulated patient transfer.

Study Design: Retrospective, radiological study. Purpose: To determine the relationship between clinical symptoms and the extent of tumor occupation of the spinal canal by cauda equina schwannoma. Overview of Literature: Little is known about the relationship between the size of tumors of the cauda equina and the manifestation of clinical symptoms. We analyzed this relationship by estimating the percentage of tumor occupation (PTO) in the spinal canal in cauda equina schwannomas and by correlating this parameter with the presence and severity of clinical symptoms. Methods: Twenty-two patients (9 men and 13 women; age, 19–79 years; mean age, 55.3 years) who were radiologically diagnosed with schwannomas of the cauda equina between April 2004 and July 2014 were retrospectively analyzed. PTO was measured in axial and sagittal magnetic resonance imaging slices in which the cross-sectional area of the tumor was the largest. Data regarding clinical symptoms and results of physical examinations were collected from patient medical records. PTO differences between symptompositive and -negative groups were analyzed for each variable. Results: In the 4 cases in which tumor presence was not related to clinical symptoms, PTO was 5%–10% (mean, 9%) in axial slices and 23%–31% (mean, 30%) in sagittal slices. In the 18 cases in which symptoms were associated with the tumor, PTO was 11%–86% (mean, 50%) in axial slices and 43%–88% (mean, 71%) in sagittal slices. PTO in axial slices was significantly higher in the presence of Déjèrine symptoms and/or muscle weakness, a positive straight leg raise test, and a positive Kemp sign. Conclusions: PTO >20% in axial slices and >40% in sagittal slices can be an indication of symptomatic cauda equina schwannoma.
