Objective To explore the value of bedside ultrasound used by ICU doctor in the rapid diagnosis of traumatic abdominal,and to evaluate the advantage of bedside ultrasound in the treatment decision.Methods 60 patients with traumatic abdominal blood in our hospital admitted to the ICU were selected.All patients were checked through bedside ultrasonography by physicians with professional training of ICU,bedside ultrasound and abdominal CT and abdominal flat piece of traumatic hematocelia,and compared the diagnosis of the time of the bedside ultrasound,abdominal CT and abdominal X -ray and ultrasound physician ultrasound examination.Results The difference of abdominal blood detection rate between bedside ultrasonography and abdominal computed tomo-graphy (CT)had no statistical significance (P >0.05);bedside ultrasonography of abdominal blood detection rate was higher than plain film of the abdomen,the difference was statistically significant (χ2 =73.346,P <0.01);bed-side ultrasound received a preliminary diagnosis of time -consuming (4.37 ±2.1)min was significantly lower than that of the examination of ultrasound physicians (13.86 ±5.6)min,abdominal CT (22.13 ±6.9)min and abdominal plain film (28.19 ±7.32)min,the differences were statistically significant (t =3.947,14.607,21.139,26.338,all P <0.01 ).Conclusion By the professional training of ICU physicians for bedside ultrasound traumatic blood abdominal patients can make a more accurate diagnosis,time -shorten,more accord with the requirement of treating critically ill patients in ICU,which has important clinical value for trauma abdominal blood in early rapid diagnosis and treatment.

AIM: To investigate the effects of advanced glycation end products (AGEs) on the expression of plasminogen activator inhibitor-1 (PAI-1) in rat mesangial cells and its relationship with extracellular matrix accumulation. METHODS: Rat mesangial cells were treated with AGE-modified bovine serum albumin or native bovine serum albumin. Normal mesangial cells without any treatments were used as control. Fibronectin (FN), collagen Ⅳ, PAI-1 protein contents were detected by ELISA. PAI-1 mRNA was analyzed by reverse transcriptase-polymerase chain reaction (RT-PCR). RESULTS: AGEs (0-200 mg/L) did not influence mesangial cells proliferation, but stimulated FN , collagen IV and PAI-1 contents in mesangial cell cultured medium in different degrees. AGEs also increased PAI-1 mRNA expression. CONCLUSION: AGEs increase the expression of PAI-1 in rat mesangial cells. AGEs may reduce ECM degradation through increasing PAI-1 expression, which may be one of the mechanisms of ECM accumulation in diabetic nephropathy.
