The immune-stromal cell interactions play a key role in health and diseases.In periodontitis,the most prevalent infectious disease in humans,immune cells accumulate in the oral mucosa and promote bone destruction by inducing receptor activator of nuclear factor-κB ligand(RANKL)expression in osteogenic cells such as osteoblasts and periodontal ligament cells.However,the detailed mechanism underlying immune-bone cell interactions in periodontitis is not fully understood.Here,we performed single-cell RNA-sequencing analysis on mouse periodontal lesions and showed that neutrophil-osteogenic cell crosstalk is involved in periodontitis-induced bone loss.The periodontal lesions displayed marked infiltration of neutrophils,and in silico analyses suggested that the neutrophils interacted with osteogenic cells through cytokine production.Among the cytokines expressed in the periodontal neutrophils,oncostatin M(OSM)potently induced RANKL expression in the primary osteoblasts,and deletion of the OSM receptor in osteogenic cells significantly ameliorated periodontitis-induced bone loss.Epigenomic data analyses identified the OSM-regulated RANKL enhancer region in osteogenic cells,and mice lacking this enhancer showed decreased periodontal bone loss while maintaining physiological bone metabolism.These findings shed light on the role of neutrophils in bone regulation during bacterial infection,highlighting the novel mechanism underlying osteoimmune crosstalk.

Chinese Medicine Questionnaire (CCMQ-J) consists of sixty independent questionnaires and 9 physical constitutions called subscales. One type is balanced constitution (i.e., gentleness), and the following eight types represent unbalanced constitution: Qi-deficiency constitution, Yang-deficiency constitution, Yin-deficiency constitution, Phlegm-dampness constitution, Damp-heat constitution, Stagnant Blood constitution, Stagnant Qi constitution, and Inherited Special constitution. In this study, we proposed to determine optimal number of groups in 851 participants recruited from crowdsourcing answered CCMQ-J questionnaire consisting of 60 questions. In the present study, we applied k-means clustering with gap statistics to the questionnaire data and the number of optimal groups was estimated by five. The five groups are mainly characterized by 3 subscales in CCMQ-J, i.e. (i) two subscales corresponding to Yang-deficiency and Qi-depress, (ii) three subscales corresponding to gentleness, Yang-deficiency and Qi-depress (iii) Yang-deficiency, (iv) gentleness, and (v) Qi-depress. In the crowdsourcing survey, two subscales, Yang-deficient and Qi-depress are the most frequently occurred in current Japanese people.

In this study, we proposed an approach to interpret the classification of body constitution based on the Japanese Version of Constitution in Chinese Medicine Questionnaire (CCMQ-J) in terms of an augmented questionnaire combining seven independent questionnaires. The augmented questionnaire consists of 254 questions in terms of seven categories of attributes, which are the (i) basic information (BI), (ii) disease (DI), (iii) social factors (SO), (iv) mental factors (ME), (v) dietary habits (DH), (vi) sleeping state (SL), and (vii) sub-health (SH). The partial least square (PLS) regression has been adopted to model the correlations between the scores of body constitutions and the questions, and their results show that the body constitution can be represented by the linear combination of the questions substantially (correlation coefficients between the true and predicted constitutions are all above 0.7). Moreover, by using the crowdsourcing technique in data collection, a total of 851 samples (350 males and 501 females between 20 and 85 years old) samples with diverse geographical backgrounds in Japan have been collected, from which new medical implications have been extracted through the discussion in a Traditional Chinese Medicine standpoint. This study serves as a crucial step for validating the philosophy of ancient Chinese medicine by the state-of-the-art information science techniques and facilitating the use of the CCMQ-J in public healthcare.

We examined the association of 9 types of the Constitution in Chinese Medicine and body mass index (BMI) and/or the energy intake, which are considered to relate with lifestyle diseases. We obtained data on the Constitution in Chinese Medicine Questionnaire, height, weight, a Food Frequency Questionnaire, age, and exercise habits from 729 subjects through the Internet. We performed multiple comparison tests on the BMIs, the energy intake or the adjusted energy intake for age, height, weight, and exercise habits between types of the Constitution in Chinese Medicine. In women, the BMIs were not significantly different between personality types of the Constitution in Chinese Medicine. In men, the BMI of the yang-deficiency group was significantly lower than the ones of the gentleness, qi-deficiency, or phlegm-dampness groups (p = 0.0098, 0.029, or 0.040, respectively). No significant relationship was found between energy intake or adjusted energy intake and types of the Constitution in Chinese Medicine in men or women. Further studies are required to determine whether the Constitution in Chinese Medicine are useful for reducing risk factors for lifestyle diseases.

Variety of accessibility to edible species in different regions has climatic and historical roots. In the present study, we try to systematically analyze 28,064 records of relationships between 11,752 edible species and 228 geographic zones by hierarchical clustering. The 228 geographic regions were classified into 11 super groups named as A to K, which were further divided into 39 clusters (CLs). Of them, at least one member of each of 28 CLs is associated to 20 or more edible species according to present information of KNApSAcK DB (http://kanaya.naist.jp/KNApSAcK_World/top.jsp). We examined those 28 CLs and found that majority of the members of each of the 27 CLs (96%) have specific type of climate. Diversity of accessibility to edible species makes it possible to separate 8 geographic regions on continental landmasses namely Mediterraneum, Baltic Sea, Western Europe, Yucatan Peninsula, South America, Africa and Arabian Peninsula, Southeast Asia, and Arctic Ocean; and three archipelagos namely, Caribbean Islands, Southeast Asian Islands and Pacific Islands. In addition, we also examined clusters based on cultural exchanges by colonization and migration and mass movement of people and material by modern transportation and trades as well as biogeographic factors. The era of big data science or data intensive science make it possible to systematically understand the content in huge data and how to acquire suitable data for specific purposes. Human healthcare should be considered on the basis of culture, climate, accessibility of edible foods and preferences, and based on molecular level information of genome and digestive systems.

Abstract
Objective : In this study, we conducted a survey on both the use of supplements by customers and information provided by pharmacists, to clarify customer understanding. We also sought to ascertain the actual current state of information provided by pharmacists to customers, as well as investigating both how, and to what extent, pharmacists should be involved in customers 'use of supplements.
Methodology : During regular pharmacy visits, pharmacists used a questionnaire to interview 1,253 customers, in 14 community pharmacies, in Tokyo and Hokkaido, respectively. A different questionnaire, designed for pharmacists, was also given to 289 pharmacists who were either working in those same pharmacies, or who attended the Conference on Pharmaceutical Sciences in Hokkaido (2011, Sapporo).
Results : The results of the survey showed that approximately 50% of consumers greatly desired the provision of safety and efficacy information about supplements by pharmacists. However, few pharmacists answered customers' questions satisfactorily (only 7.3% of total responses).
The results also indicated that only 30% of pharmacists actively gathered information about supplements, despite the fact that 67.5% of pharmacists were aware that they were expected to do so by customers, in their roles as primary information providers regarding such treatments. Furthermore, even those pharmacists who checked information regarding supplements depended mostly on information acquired from the Internet.
Conclusion : There is a large gap between customers' expectations for explanation of supplements and the reality of such explanations, and the information actually provided by pharmacists. In order to live up to their customers' expectations, pharmacists should foster both wider dissemination and better understanding of evidence-based information about supplements. Pharmacists should also provide integrated management of drugs and supplements for patients.

The efficacy of Landiolol hydrochloride (Onoact®) for the treatment of arrhythmia was studied in 10 adult patients who underwent cardiovascular surgery. Onoact was continuously infused at a mean rate of 0.018 mg/kg/min initially and followed by 0.01 mg/kg/min. After the initiation of Onoact infusion, supra-ventricular tachycardia was eliminated in 5 out of 6 patients, and ventricular tachycardia disappeared in all 4 patients. The decrease in systemic blood pressure was not significant. Low-dose continuous infusion of Onoact was safe and effective even in patients just after cardiovascular surgery.
