Students in their 5th and 6th year of University of Tsukuba, School of Medicine, enter into a clinical clerkship. They record medical charts and flow sheets and they present at clinical rounds.
1) From 2000 to 2005, a questionnaire survey was conducted to evaluate the clinical clerkship in the rheumatology division. We also evaluated the influence of the introduction of infliximab therapy (October 2003) on the students' experience.
2) Evaluation of the clinical clerkship by the students was improved by attending the infliximab ward. Students felt more involved in the treatment of the patients by preparing drip infusion sets, disssolving infliximab, assisting with the drawing of blood and drip infusions, checking of the vital signs every 30 minutes, and recording charts.
3) Students realized the improvement of rheumatoid arthritis with therapy and the changes in the patients' emotional status after the introduction of infliximab.

Transforming growth factor-beta (TGF-beta) is a highly pleiotropic cytokine playing pivotal roles in immune regulation. TGF-beta facilitates tumor cell survival and metastasis by targeting multiple cellular components. Focusing on its immunosuppressive functions, TGF-beta antagonists have been employed for cancer treatment to enhance tumor immunity. TGF-beta antagonists exert anti-tumor effects through #1 activating effector cells such as NK cells and cytotoxic CD8+ T cells (CTLs), #2 inhibiting regulatory/suppressor cell populations, #3 making tumor cells visible to immune cells, #4 inhibiting the production of tumor growth factors. This review focuses on the effect of TGF-beta on T cells, which are differentiated into effector T cells or newly identified tumor-supporting T cells.

PURPOSE: Patients with gestational diabetes mellitus (GDM) have been reported to exhibit the same genetic susceptibility as that observed in those with type 2 diabetes mellitus (T2DM). Recent polymorphism studies have shown that several genes are related to T2DM and GDM. The aim of this study was to examine whether certain candidate genes, previously shown to be associated with T2DM, also offer a specific genetic predisposition to GDM. MATERIALS AND METHODS: The current study was conducted in 136 Korean pregnant women, who gave birth at Gil Hospital, from October 2008 to May 2011. These study subjects included 95 subjects with GDM and 41 non-diabetic controls. We selected the specific genes of PPARgamma2, IGF2BP2, and KCNQ1 for study and amplified them using the polymerase chain reaction. This was followed by genotyping for single nucleotide polymorphisms. We then compared the genotype frequencies between patients with GDM and non-diabetic controls using the chi2 test. We obtained and analyzed clinical information using Student's t-test, and statistical analyses were conducted using logistic regression with SPSS Statistics software, version 19.0. RESULTS: Significant differences were observed in maternal age, body mass index, weight gain and weight at time of delivery between the groups compared. Among pregnant women, polymorphisms in PPARgamma2 and IGF2BP2 were shown to be highly correlated with GDM occurrence, whereas no correlation was found for KCNQ1 polymorphisms. CONCLUSION: Our results indicated that genetic polymorphisms could also be of value in predicting the occurrence and diagnosis of GDM.
