This study was designed to clarify the relationship between Sho, which represents a clinical status in oriental medicine, and the clinical parameter in type 2 diabetes mellitus (DM). In 65 patients [male 27 (mean age: 60.9±12.0) and female 38 (64.9±8.4)] with type 2 DM, we determined the incidence of Sho [In/Yo (yin/yang) and Kyo/Jitsu (xu/shi)], measured the indices of insulin resistance (fasting plasma insulin level: F-IRI and HOMA-IR), and analyzed the relationship between them. The incidences of In, intermediate, Yo were 30.8%, 32.3% and 36.9%, respectively, while the incidence of Kyo, intermediate, Jitsu were 30.8%, 33.8%, and 35.4%, respectively. The incidences of combined Sho represented as Yo-Jitsu, intermediate-intermediate, In-Kyo, Yo-Kyo, intermediate-Jitsu, Yo-intermediate, In-intermediate and intermediate-Kyo were 26.2%, 21.5%, 18.5%, 10.8%, 7.7%, 6.2%, 6.2% and 3.1%, respectively. F-IRI was significantly higher in patients with Jitsu than those with Kyo (p=0.044) and significantly higher in patients with Yo-Jitsu than those with In-Kyo (p=0.033). HOMA-IR is significantly higher in patients with Yo-Jitsu than those with In-Kyo (p=0.017). Our study indicated that the incidences of In and Yo were almost the same and those of Kyo and Jitsu were also nearly the same in patients with type 2 DM. In addition, our study suggested that Sho of Jitsu and Yo-Jitsu could be related with the degree of insulin resistance in patients with type 2 DM.

As part of U-40 activities, chapters have traditionally held sessions of lectures and hands-on as the Basic Lecture Course (BLC) to improve the basic skills and knowledge of young cardiovascular surgeons. Because of the COVID-19 epidemic, we have shifted our activities from onsite to online. This column focuses on “management of postoperative delirium and pain” in the lecture of “Postoperative Management in Cardiovascular Surgery” given by the Chubu Chapter in 2020. We summarize the lecture and report the results of a questionnaire survey of the U-40 members.
