    Objective To explore the opinions of outpatients concerning a new communication method: the selfmanagement of assessed personal problems in health information records (SAPPHIRE) using patients' mobile phones to store and share medical content (medical SAPPHIRE, or m-SAPPHIRE). Methods A cross-sectional questionnaire survey. Patients Outpatients who visited us from March 1 to May 30, 2012, were asked to complete a questionnaire survey regarding SAPPHIRE and m-SAPPHIRE. The m-SAPPHIRE data consisted of a problem list, height, weight, waist size and active medication list. Ten questions were asked regarding the usefulness of m- SAPPHIRE, the sharing of m-SAPPHIRE and the use of mobile phones to store m-SAPPHIRE data. Results One hundred and ninety-three patients (male/female, 79/114; mean age, 57±21 years) were registered: 95.9% answered that m-SAPPHIRE would be useful, 98% agreed to manage their personal health records by themselves, and 95.8%, 93.8%, and 92.8% of the patients responded that they would allow m- SAPPHIRE information to be shared with family members, medical workers, and health care providers, respectively. Of the patients, 75.1% responded that they owned a mobile phone, and 43.5% answered that they could enter m-SAPPHIRE information into a mobile phone by themselves, while 27.5% responded that they could do so with someone's help. Conclusion Patients believe that m-SAPPHIRE would be useful for retrieving their health records during emergency situations or for sharing with family members and medical and health care providers. SAPPHIRE using mobile phones could be an inexpensive and legal method for sharing medical data. © 2013 The Japanese Society of Internal Medicine.

    Background: Recent advances in multidisciplinary treatment approaches have improved the overall prognosis of pediatric brain tumors, but some patients remain refractory to treatment and do poorly. Several molecularly targeted therapies are under development for the treatment of brain tumors, and high-grade gliomas in adults are a particular area of study. Procedure: To better understand if these new therapies can be used in pediatric populations, we examined the expression of the following seven marker genes involved in signaling pathways targeted by new therapies: β-catenin, suppressor of fused (SUFU), erythroblastic leukemia viral oncogene homolog (ERBB) 2, platelet-derived growth factor receptorα (PDGFRα), proliferating cell nuclear antigen (PCNA), secreted protein acid and rich in cysteine (SPARC), and granulocyte colony-stimulating factor receptor (G-CSFR). Samples from 27 patients with the primitive neuroectodermal tumor (PNET)/medulloblastomas (MBs) (n=8), ependymomas (n=5), or gliomas (n=14) were assessed by quantitative real-time PCR. [Correction made here after initial online publication]. We assigned an EXP score to compare across samples and determined the levels of gene expression among tumor cell types. Results: Gene expression varied among the different tumors, but, within a tumor type, clear expression patterns were seen. The expression of SUFU, ERBB2, and PCNA in metastatic MBs were greater than that seen in non-metastatic MBs. Most glioma cases highly expressed PDGFRα and G-CSFR. Additionally, the expression patterns of gliomas and ependymomas were similar (r=0.77, P=0.04), but PNET/MBs substantially differed from gliomas (r=-0.37, P=0.41) or ependymomas (r=0.23, P=0.62). Conclusions: The development of new drugs targeting up-regulated pathways may be useful for the treatment of pediatric brain tumors. As new drugs are developed, gliomas and ependymomas may be treated with similar compounds. © 2011 Wiley Periodicals, Inc.

    <b>Objective:</b> We screened examinees with hypercalcemia in Ningen Dock for primary hyperparathyroidism.<br><b>Methods:</b> Examinees were screened from July 1995 to December 2010. Serum calcium (Ca), phosphate and albumin (Alb) were measured using an auto-analyzer. Examinees with hypercalcemia were selected for primary hyperparathyroidism screening and their serum Ca levels were adjusted using serum Alb levels to provide corrected serum calcium(cCa) levels. For those with high serum Ca and cCa levels, serum parathyroid hormone(PTH)levels were measured for diagnosis of primary hyperparathyroidism. We also investigated examinees from July 2001 to December 2010 regarding a relationship between primary hyperparathyroidism and hypercalcemia. <br><b>Results:</b> The total number of examinees was 1,936 (1,324 males, 612 females). The first case of serum high Ca and cCa levels was the 817th examinee since our Ningen Dock started, and the second was the 1,737th (920th case after first detected case). These 2 examinees were diagnosed with primary hyperparathyroidism due to high serum PTH levels. When we investigated 1,615 examinees during the period July 2001 to December 2010, high serum Ca levels were detected in 24 cases(1.5%). High serum cCa levels were detected in 3 cases, consisting of 2 cases of primary hyperparathyroidism and one of multiple myeloma. <br><b>Conclusions:</b> On screening for primary hyperparathyroidism in Ningen Dock examinees, we detected 2 cases of primary hyperparathyroidism. The first case was the 817th examinee and the second case the 1,737th examinee. The detection rate for hyperparathyroidism in Ningen Dock seems to be about 1/1,000.

    Introduction: Trilateral retinoblastoma (TRb) is an intracranial neurogenic tumor associated with unilateral or bilateral retinoblastoma and has very poor prognosis. Patients typically die from leptomeningeal tumor dissemination. Case report: A 3-year-old girl who had been diagnosed with TRb had a disseminated relapse after a tumorectomy, cerebrospinal irradiation, and conventional chemotherapy. The disseminated tumor disappeared after the first autologous peripheral blood stem cell transplantation (PBSCT) with high-dose melphalan and thiotepa. During the second complete remission, a second autologous PBSCT with high-dose busulfan and melphalan was performed. Seven months after the first PBSCT, the second relapse occurred, and we subsequently performed an allogeneic PBSCT with myeloablative chemotherapy consisting of melphalan, thiotepa, and cyclophosphamide. The patient showed clinical improvement after the allogeneic PBSCT. Conclusion: Although high-dose chemotherapies have a curative effect for some patients with TRb, the prognoses of disseminated tumors are still poor. Further examination of the high-dose chemotherapy is necessary for the time, the conditioning drugs, and the hematopoietic stem cell sources. © Springer-Verlag 2011.

    We performed double high-dose chemotherapy followed by peripheral blood stem cell transplantation (PBSCT) in 3 children with medulloblastoma and primary leptomeningial dissemination, including spinal metastasis. After resection of the main tumor mass, 30.6 Gy whole craniospinal radiation therapy and 4 or 5 courses of conventional chemotherapy with vincristine (1.5 mg/m2), carboplatin (560 mg/m2), ifosfamide (9000 mg/m2), and etoposide (500 mg/m2), and 2 courses of high-dose thiotepa (680 mg/m2) and melphalan (240 mg/m2) therapy with PBSCT were administered. Two patients with low erythroblastic leukemia viral oncogene homolog 2 (ERBB2) gene expression achieved long-term survival (41 mo and 40 mo) but the patient with high ERBB2 expression relapsed 9 months after the second PBSCT. © 2010 Lippincott Williams & Wilkins, Inc.

    Aberrant DNA methylation is frequently observed in adults with myelodysplastic syndrome (MDS), and is recognized as a critical event in the disease's pathogenesis and progression. This is the first report to investigate the methylation status of p15 and p16, cell cycle regulatory genes, in children with MDS (n = 9) and juvenile myelomonocytic leukaemia (JMML; n = 18) by using a methylation-specific polymerase chain reaction. The frequency of p15 hypermethylation in paediatric MDS was 78% (7/9), which was comparable to that in adult MDS. In contrast, p15 hypermethylation in JMML was a rare event (17%; 3/18). In JMML, clinical and laboratory characteristics including PTPN11 mutations and aberrant colony formation were not different between the three patients with hypermethylated p15 and the others. Aberrant methylation of p16 was not detected in children with either MDS or JMML. Since p15 and p16 genes were unmethylated in two children with JMML, in whom the disease had progressed with an increased number of blasts, a condition referred to as blastic crisis, we infer that the aberrant methylation of these genes is not responsible for the progression of JMML. The results suggest that demethylating agents may be effective in most children with MDS and a few patients with JMML. © 2005 Blackwell Publishing Ltd.

    Language:Japanese

    Basophilic granulocytes (basophils) are a very small population of peripheral blood leukocytes. Because basophils have high-affinity immunoglobulin E receptors (Fce{open}RI) and secrete chemical mediators that contain histamine, they are thought to be very similar to mast cells. However, research characterizing the function of basophils was slow to proceed and their unique function and importance were not established for a significant period of time. Recently, a series of studies have characterized the role of basophils in anaphylactic shock, chronic allergic reactions, and other human immunological reactions. These studies have shown that basophils are not a supplementary cell type but key players in very serious immune reactions. In this chapter we introduce the recently discovered characteristics of basophils. In addition, we consider how these aspects are clinically important and are connected with new cellular or molecular treatments for allergic reactions. © 2012 Nova Science Publishers, Inc.

    川崎病の原因を確定するため、過去に申請者が患者の上部消化管から検出した「病原体の遺伝子」および川崎病の主要な合併症である冠動脈瘤形成の発端となる「病原体特異的なheat-shock protein(HSP) 」を川崎病患者の臨床検体から検出しうるツールを開発し、疾患対象患者(同年齢層の川崎病以外の発熱を伴う感染症患者)との比較検討を試みた。
    I. 血液中の細菌遺伝子 (川崎病群20例、疾患対照群16例)の検出:川崎病群と疾患対照群間で、検出される細菌の種類に関しては明瞭な差異は認められなかった。
    2. 血清Heat-shock 蛋白 (HSP) 60 の検出 (川崎病群30例、疾患対照群16例):川崎病急性期血清で認められるものと予想していたAcinetobacter 特異的 HSP60は、疾患対照群の血清中でも1例認められ、川崎病において特異的に血中に検出される蛋白と結論することはできなかった。AcinetobacterもしくはNesseria HSP60の患者血清中検出率は、川崎病群で10%、疾患対照群で6%程度であった。
    3. 咽頭ぬぐい液の細菌遺伝子の検出 (川崎病群22例、疾患対照群18例):申請者らの過去の検討で川崎病の発症に関与すると推測していたNeisseria属の細菌は、新種のものであったが、細菌遺伝学的にはN.subflavaに最も近似するものであった。しかし、同菌は、川崎病群で疾患対照群の約2倍の検出頻度はあるものの、Fisher's exact testでは統計的有意差は認められなかった。一方、Enterobacteriaceaeの遺伝子は川崎病群でのみ検出され、疾患対照群では一切検出されなかった。
    新型コロナウイルス感染拡大防止対策としての申請者の所属する医療施設が入院制限を設けた影響で、川崎病患者、疾患対照患者の入院受け入れが遅れ、予定の対象サンプル数が集まっていないため。
    川崎病の咽頭粘膜で特異的に分子生物学的手法によって検出されたEnterobacteriaceaeは、「腸内細菌科」と呼ばれ、多数の属を含むため、遺伝子のシークエンスを試み細菌種を同定する。目標症例数は、川崎病50例、疾患対照50例であるため、このサンプル数に達するまで、サンプリングは継続する。これまでの保存細菌、保存血清および同年度収集を試みる血液検体において、同定されたEnterobacteriaceae科の菌種の遺伝子およびHSP60解析を行う。

    We examined the utility of the pyruvate kinase deficiency (PKD) mouse origin iPS (PKD-iPS) cell towards development of the new gene therapy to PKD.
    In the established PKD-iPS cell, we found the same DNA variation that is existed in the cells of model mouse. The iPS cells were be able to differentiate to the erythroid cells, but the number of erythrocytes were decreased compared with cells from the wild-type iPS cells. Furthermore, we made the guide RNA / Cas9 gene expression vector and the donor vector for repairing the varied PKLR gene. To transfer these vectors into iPS cells efficiently, we examined the transgene efficiency, and get transfer efficiency 50% that is exceeding 40% of the transgene efficiency needed for genome edit.

    We paid attention to TEK and CD34 expressed to both of the blood cell and the vascular endothelial cell to examine the plasticity of the umbilical cord blood first. Restructuring of the human hematopoiesis was recognized in the all cases when 1x 10^4 CD34+TEK+ cells and CD34+TEK- cells which it could get from human umbilical cord blood, were transplanted to each 7 ischemic mouse models. Furthermore, though differentiation to the endothelial cells were confirmed with CD34+TEK+ cells transplantation mouse by the all cases, a differentiation to the endothelial cells that only three cases were restructured of the human hematopoiesis in the high rate was recognized with a CD34+TEK-cell transplantation mouse. It could think that it had differentiation potency to the endothelial cells that CD34+TEK+ cells are higher than CD34+TEK- cells, and the possibility that undifferentiated precursor cell, that is, hemangioblast existed was suggested by the inside of the umbilical cord blood more than TEK+ endothelial precursor cell. The analysis of the gene expression which controls the differentiation, proliferation of the umbilical cord blood subsequently was done. As for the hematopoiesis restructuring pattern after the umbilical cord blood transplantation, it knows that it is different from the thing after the bone marrow transplantation. ERα mRNA was expressed in the leukemia cell line of most B-cell lineage, and ERβ mRNA got the result that the Daudi cell was strongly expressed only in the lymphoid cell with the maturity tendency. And, both expressions were recognized as a in the predominance with umbilical cord blood mononuclear in the low quantity of a measurement limit. Furthermore, we did the co-culture experiment of the umbilical cord blood and the mouse stromal cell (HESS-V) to establish the line to cultivate stem cell under the serum-free place. As for the umbilical cord blood CD34 positive cell, it found that it could be cultivated, it was maintained without differentiation, by using HESS-V to the approx. 3 weeks. At present, use this experimental line, and do a change in nature of the steroid and the umbilical cord blood mononuclear by the addition such as a hematopoietic growth factor, an ER congenic experiment, and so on, and the examination of the potential of the umbilical cord blood is being done.
