Objective To explore the value of contrast-enhanced ultrasound(CEUS) in the diagnosis of hematoma and active hemorrhage of renal trauma. Methods Totally 28 patients with renal trauma were examined by conventional ultrasound and CEUS,respectively,including 24 cases caused after renal biopsy,4closed trauma. The detectability of renal hematoma and active hemorrhage with these two methods were compared. All patients were identified by CT or follow-up studies with ultrasound. Results The detectability of renal hematoma with conventional ultrasound and CEUS were 67. 86% (19/28), 92. 86%(26/28), respectively. There was statistically different for detectability in the diagnosis ( P <0.05), and the extent of hematoma was more obvious with CEUS. CEUS diagnosed 7 of 26 were renal hematoma with active hemorrhage,which were difficult to be detected with conventional ultrasound. For renal hematoma,the features of CEUS were no enhancement found in every phase; for renal hematoma with active hemorrhage,the contrast agents overflowed from injured blood vessels and formed irregular remarkable enhanced regions. Conclusions CEUS is useful in diagnosing hematoma and identifying the extent and active hemorrhage of renal trauma,in addition,CEUS is valuable in detecting complications after renal biopsy.

This study was aimed to investigate the protective effect of catalpol against high glucose induced injury on vascular endothelial cells (ECV-304). ECV-304 cells were culturedin vitro. MTT method was applied to detect cell viability. NO and LDH level were measured by spectrophotometer method. The effect of catalpol against high glucose induced injury on ECV-304 was observed. The results showed that there were no obvious changes in cell viabilities of ECV-304 cultured in normal concentration of glucose medium among groups with different concentrations of catalpol. Compared with the control group, cell viability was significantly decreased (P< 0.01), the NO secretion was significantly reduced (P< 0.01), the LDH level was increased obviously (P< 0.01) in the high glucose (30 mmol·L-1 glucose) injury model group. The high osmotic (24.5 mmol·L-1 mannitol) group was set up as a positive control. Comparison between the low dose (1 ng·μL-1 catalpol + 30 mmol·L-1 glucose), middle dose (10 ng·μL-1 catalpol+ 30 mmol·L-1 glucose), and high glucose (30 mmol·L-1 glucose) injury model group showed no changes on cell viability and NO (P> 0.05); while the LDH level was reduced (P< 0.01). Comparison between the high dose catalpol (100 ng·μL-1 catalpol + 30 mmol·L-1 glucose) group and the high glucose model group showed that the cell viability was obviously increased (P< 0.01); NO secretion was increased (P< 0.05); and the LDH level was obviously reduced (P< 0.01). It was concluded that catalpol had protective effect against high glucose induced ECV-304 injury through the regulation of NO and LDH level. The effect of high dose was obvious.
