Adrenocortical carcinoma (ACC) with inferior vena cava thrombosis is rare and has a poor prognosis, and the current literature overwhelmingly supports aggressive surgical intervention. This article summarizes the management of a patient with ACC with inferior vena cava thrombosis, and discusses the feasibility of detailed preoperative imaging data and intraoperative ultrasound to assess the superior and inferior boundaries of ACC with inferior vena cava thrombosis, while describing the intraoperative ultrasound-guided surgical planning and procedure for ACC with retrohepatic inferior vena cava tumor thrombus. Furthermore, it also demonstrates that it is feasible to accurately assess the superior and inferior boundaries of ACC with inferior vena cava thrombosis by preoperative multimodal imaging and intraoperative ultrasound, determine the mode of flow blockage during the operation, and obtain radical resection of the tumor.

We investigated the effect of supplementing fertilization medium and/or culture medium with astaxanthin (AST) on the two phases of in vitro fertilization: gamete fertilization and embryo development. Methods: Mouse cumulus-oocyte complexes were divided into four groups with 5 µM AST added to the fertilization medium (group 3, n=300), culture medium (group 2, n=300), or both media (group 4, n=290). No AST was added to the control group (group 1, n=300). Results: The fertilization rate was significantly higher (p<0.001) in the groups using AST supplemented fertilization medium (group 3, 79.0%; group 4, 81.4%) than those without AST (group 1, 56.3%; group 2, 52.3%). The blastocyst rate calculated from the two-cell stage was significantly lower (p<0.001) in the groups using AST-supplemented embryo culture medium (group 2, 58.0%; group 4, 62.3%) than in those without AST (group 1, 82.8%; group 3, 79.8%). The blastocyst rate calculated from the number of inseminated oocytes was highest in group 3 (189/300, 63.0%) and lowest in group 2 (91/300, 30.3%) with statistical significance compared to other groups (p<0.001). There were significantly higher numbers of cells in the inner cell mass and trophectoderm, as well as significantly higher total blastocyst cell counts, in group 3 than in the control group. Conclusion: An increased blastocyst formation rate and high-quality blastocysts were found only in the fertilization medium that had been supplemented with AST. In contrast, AST supplementation of the embryo culture medium was found to impair embryo development.

Telemedicine has been an emerging method for delivering healthcare services due to the challenges brought by the COVID-19 pandemic. This descriptive quantitative correlational study is aimed at assessing the knowledge, attitudes and perceptions (KAP), and their relationship among adults aged 18-34 without prior experience in the use of telemedicine in Manila, Philippines during the COVID-19 pandemic. The study had 322 eligible respondents who answered an online survey questionnaire of three parts that asked for their socio-demographic profile, KAP on telemedicine. Descriptive statistics, profile analysis and Spearman's rho were utilized as statistical tools. The respondents' knowledge was on an average to low level, and attitude and perception towards telemedicine were both neutral. Results showed no significant difference between the KAP of the respondents when analyzed according to socio-demographic variables. Knowledge and attitude have a weak positive linear relationship while knowledge and perception have a moderate positive linear relationship. A strong positive linear relationship was indicated between attitude and perception. A positive attitude can be attributed to a positive perception towards telemedicine but both do not consequently come from high knowledge levels of it.

In spleen tissue, there was significantly increased IFN-γ (P<0.05) and TGF-β (P<0.05) in SGTHD group and was significantly increased IFN-γ (PO.05), IL-10 (P<0.01)and TGF-β (PO.001) in SGG group compared with normal group. Conclusion High doses San Gen talkh medicine and San Gen granule medicine can support cellular immune system, humoral immune system on healthy rats.

Interleukin-33(IL-33) is a new member of the interleukin-1 (IL-1) cytokine superfamily. It can activate mast cells, lymphocytes and macrophages to produce Th2 cytokines and plays a very important role in inflammation, infection, and autoimmune disease. The classical signal pathway of IL-33 includes the isotrimer of ST2 and interleukin-1 receptor accessory protein (IL-1 RAcP), which transduces signals into cells. The IL-33/ST2 signaling pathway affects bone metabolism by activating T and B lymphocytes. This article reviews the role of the IL-33/ST2 signaling pathway in bone metabolism. The results of a literature review showed that at present, scholars at home and abroad still dispute the role of IL-33 in bone metabolism. Some scholars believe that IL-33 can inhibit osteoclast formation, and IL-33 has been recently implicated in physiological bone remodeling. However, other scholars believe that IL-33 can promote osteoclast formation and differentiation, which leads to bone absorption. IL-33 and its signaling pathway are involved in bone metabolism of alveolar bone in periodontitis and periapical periodontitis. The specific mechanism remains unclear, and further studies are warranted.

PURPOSE: This study examined the relationship between caffeine intake and metabolic syndrome in Korean adults using the 2013 ~ 2016 Korea National Health and Nutrition Examination Survey data (KNHANES). METHODS: The caffeine database (DB) developed by Food and Drug Safety Assessment Agency in 2014 was used to estimate the caffeine consumption. The food and beverage consumption of the 24 hr recall data of 2013 ~ 2016 KNHANES were matched to items in the caffeine DB and the daily caffeine intakes of the individuals were calculated. The sample was limited to non-pregnant healthy adults aged 19 years and older, who were not taking any medication for disease treatment. RESULTS: The average daily caffeine intake was 41.97 mg, and the daily intake of caffeine of 97% of the participants was from coffee, teas, soft drinks, and other beverages. Multivariate analysis showed that the caffeine intake did not affect metabolic syndrome, hypertension, low HDL-cholesterol, and abdominal obesity. Diabetes and hypertriglyceridemia, however, were 0.76 (95% CI: 0.63 ~ 0.93), and 0.87 (95% CI: 0.77 ~ 0.98) in third quintile (Q3), and 0.66 (95% CI: 0.53 ~ 0.82) and 0.83 (95% CI: 0.73 ~ 0.94) in fourth quintile (Q4) compared to Q1, respectively. Therefore, caffeine intake of 3.66 ~ 45.81 mg per day is related to a lower risk of diabetes and hypertriglyceridemia. CONCLUSION: The study showed that adequate caffeine intake (approximately 45 mg) was associated with a lower prevalence of diabetes and hypertriglyceridemia. Therefore, it can be used as a guideline for the adequate level of caffeine intake for maintaining health.
