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.

Since the rectus femoris muscle is associated with trauma and disorders such as muscle strain, it is often a target for evaluation and treatment. However, in many studies, measurement results were obtained from only a part of the rectus femoris muscle and used as a representative value without considering the differences across the muscle. The rectus femoris muscle may change shape with knee flexion because the structure is complicated; it has an intramuscular tendon. The purpose of this study was to assess the changes in shape of the rectus femoris muscle during flexion of the knee joint in different directions. Twelve lower limbs of 12 male university students were analyzed. The rectus femoris muscle was divided into eight parts, and short-axis images were taken with an ultrasonic diagnostic imaging device at the knee joint; in extension; flexion at 30 °, 60 °, 90 °, and 120 °; muscle thickness; muscle width; and cross-sectional area. It was suggested that the thickness of the rectus femoris muscle increased from “A” to “F” due to knee flexion, and that this increase occurred because of stretching at the same site. In “G,” there was no difference between the angle conditions; conversely, in “H,” the muscle thickness decreased due to knee flexion. It should also be noted that D and E have the greatest muscle thickness when measuring in the knee flexion position.

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.

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.
