Background: Accurate determination of the optimal insertion depth of a pediatric endotracheal tube (ETT) is quite important. The aim of this study was to create an easily available formula that can be used to determine the optimal insertion depth for a cuffed ETT even without depth marking with clear definitions of the upper and lower limits for the tip of ETT in the trachea in clinical practice. Methods: Eighty children under 12 years of age were enrolled. The depth marking of the cuffed ETT was placed at the vocal cords and both lungs were then auscultated using a stethoscope. The upper limit was radiographically defined as the position of the tip of the cuffed ETT being between the clavicles. The lower limit was defined as a distance of 5 mm above the carina. The relationship between the insertion depth and patient characteristics was analyzed to create a formula for optimal ETT insertion depth. Results: Sixty-nine ETTs were optimally placed in the trachea. There were good correlations between the optimal insertion depth of ETTs and patients characteristics (height (R = 0.92);BSA (R = 0.92);weight (R = 0.91);age (R = 0.88)). Using these patient characteristics, we created the following three formulas for calculation of the optimal insertion depth for pediatric cuffed ETTs: insertion depth (cm) = height (cm)/11 + 5.5, weight (kg)/3 + 9.5 or 11 + 3/4 × age (years). The rates of appropriate tube placement of both pediatric cuffed ETTs were 87.5% (Hi-Contour) and 85.0% (Microcuff). Conclusions: Our formula and graphs may be easy to determine the optimal insertion depth of cuffed ETT even without depth marking in clinical practice.

作者： Mutsumi Takahashi Yogetsu bando Takuya Fukui Department of Physiology The Nippon Dental University School of Life Dentistry at Niigata Niigata Japan bando Dental Clinic Ishikawa Japan Department of Sport Science Kanazawa Gakuin University of Sport Science Ishikawa Japan Japan Gymnastics Association Trampoline Committee Tokyo Japan

Objective: The purpose of this study was to examine the effects of continuous gum chewing exercise on perioral muscle strength. Methods: Thirty healthy adults (24.1 ± 2.0 years) with normal occlusion performed gum chewing exercise 3 times daily for 3 months. Each exercise session lasted 5 min and involved alternating of chewing 10 times using the left molars and then 10 times using the right molars, with the mouth closed. The effect of the exercise on oral function was evaluated by measuring tongue pressure (TP), cheek pressure (CP), and labial closure strength (LCS) immediately before starting exercise, at 2 weeks and 1, 2, and 3 months after starting exercise, and at 3 months after cessation of exercise. Changes in TP, CP, and LCS according to sex and duration of exercise were analyzed by repeated two-way ANOVA. Results: Measurements for all muscles were significantly greater in men than in women at all time points. After starting exercise, TP was markedly increased at 2 months in men and women, and both CP and LCS were markedly increased at 2 weeks in men and at 1 month in women. These effects persisted for 3 months. Three months after cessation of exercise, TP, CP, and LCS tended to decrease, but were not significantly attenuated as compared with 3 months after beginning of exercise in either sex. Conclusion: The results of this study revealed that gum chewing exercise contributed to an improvement in perioral muscle strength, and that this effect was maintained for at least 3 months after discontinuation of exercise.

International Journal of Clinical Medicine 2020年第11期11卷 719-730页

作者： Yuta bando mizuki Komatsu Masayuki Okazaki Hiroshi Kawaguchi Kosaku Nitta Department of Nephrology Jyoban Hospital Fukushima Japan Department of Nephrology Tokyo Women’s Medical University Tokyo Japan

Background: Ferric citrate hydrate is a phosphate (P)-binder drug that is indicated for patients with chronic kidney disease (CKD) undergoing maintenance hemodialysis (MHD). Objectives: The objectives of this study were to evaluate the changes in the serum mineral metabolism biomarker levels and treatment status of anemia in MHD patients receiving ferric citrate hydrate. Methods: A total of 132 adult dialysis patients were enrolled in this study. Bone turnover marker levels, anemia status and iron biomarker levels over a period of 18 months after the start of the ferric citrate hydrate treatment were extracted from the medical records of the patients. Results: At enrollment, 14 (10.6%) patients were P-binder-naïve, and 118 (89.4%) patients were receiving other P-binders. The serum P level before the start of ferric citrate hydrate treatment was ≤5.5 mg/dL in 18.8% of the patients. After 18 months of ferric citrate hydrate treatment, the proportion of patients with serum P levels ≤ 5.5 mg/dL increased to 47.7%. The mean ± standard error of the mean (SEM) of the serum P level was 7.05 ± 0.14 mg/dL at the baseline, and decreased to 5.83 ± 0.17 mg/dL after 18 months of treatment with ferric citrate hydrate. The mean ± SEM of the serum hemoglobin (Hb), ferritin, and transferrin saturation (TSAT) levels were 11.96 ± 0.76 g/dL, 71.13 ± 6.09 ng/mL, and 25.19% ± 1.21%, respectively, at the baseline, and 11.45 ± 0.13 g/dL, 124.94 ± 8.62 ng/mL, and 26.18% ± 0.99%, respectively, after 18 months of ferric citrate hydrate treatment. Conclusions: These results suggest that the serum P and anemia biomarker levels observed in this study were similar to those reported in clinical trials.

作者： Ujjal K.Gautam Yoshio bando Dmitri GOLBERG Nanoscale World Premier International Center for Materials Nanoarchitectonics and Nanoscale Materials Center National Institute for Materials ScienceNamiki 1-1TsukbaIbaraki 305-0044Japan

A focus of the current nanotechnology has shifted from routine fabrication of nanostructures to designing functional electronic devices and realizing their immense potentials for applications. Due to infusion of multi-functionality into a single system, the utilization of hetero-, core/shell and hierarchical nanostructures has become the key issue for building such devices. ZnS, due to its direct wide bandgap, high index of refraction, high transparency in the visible range and intrinsic polarity, is one of the most useful semiconductors for a wide range of electronics applications. This article provides a dense review of the state-of-the-art research activities in one-dimensional （1D） ZnS-based hetero-, core/shell and hierarchical nanostructures. The particular emphasis is put on their syntheses and applications.

作者： Guozhen SHEN Di CHEN Yoshio bando Dmitri GOLBERG National Institute for Materials Science Tsukuba 305-0044 Ibaraki Japan Department of Electrical Engineering University of Southern California Los Angeles CA 90089 USA

One-dimensional （l-D） nanostructures have been attracted much attention as a result of their exceptional properties, which are different from bulk materials. Among 1-D nanostructures, 1-D heterostructures with modulated compositions and interfaces have recently become of particular interest with respect to potential applications in nanoscale building blocks of future optoelectronic devices and systems. Many kinds of methods have been developed for the synthesis of 1-D nanoscale heterostructures. This article reviews the most recent development, with an emphasize on our own recent efforts, on 1-D nanoscale heterostructures, especially those synthesized from the vapor deposition methods, in which all the reactive precursors are mixed together in the reaction chamber. Three types of 1-D nanoscale heterostructures, defined from their morphologies characteristics, are discussed in detail, which include 1-D co-axial core-shell heterostructures, 1-D segmented heterostructures and hierarchical heterostructures. This article begins with a brief survey of various methods that have been developed for synthesizing 1-D nanoscale heterostructures and then mainly focuses on the synthesis, structures and properties of the above three types of nanoscale heterostructures. Finally, this review concludes with personal views towards the topic of 1-D nanoscale heterostructures.
