Risk classification system using the detailed positive surgical margin status for predicting biochemical recurrence after robot-assisted radical prostatectomy.

Aim: This study aimed to evaluate the risk classification system using the detailed positive surgical margin (PSM) status to predict biochemical recurrence (BCR) after robot-assisted radical prostatectomy (RARP).

Methods: We retrospectively analyzed 427 patients who underwent RARP between January 2016 and March 2020. We investigated risk factors for BCR using univariate and multivariate Cox proportional hazard regression models.

[POSTOPERATIVE RECURRENCE OF RENAL CELL CARCINOMA AFTER THE LAPAROSCOPIC PARTIAL NEPHRECTOMY].

(Objectives)The usefulness of partial nephrectomy for renal tumors has been highlighted in various guidelines. Since 2006, we have been actively performing laparoscopic partial nephrectomy for renal tumors. We investigated the postoperative recurrence of renal tumors diagnosed as renal cell carcinoma after laparoscopic partial nephrectomy.

Goreisan Inhibits Upregulation of Aquaporin 4 and Formation of Cerebral Edema in the Rat Model of Juvenile Hypoxic-Ischemic Encephalopathy.

Secondary cerebral edema regulation is of prognostic significance in hypoxic-ischemic encephalopathy (HIE), and aquaporin 4 (AQP4) plays an important role in the pathogenesis of cerebral edema. The traditional Japanese herbal medicine Goreisan relieves brain edema in adults; however, its effect and pharmacological mechanism in children are unknown. We investigated the effects of Goreisan on HIE-associated brain edema and AQP4 expression in a juvenile rat model, established by combined occlusion of middle cerebral and common carotid arteries.
