Objective To detect the expression level and procoagulant activity of tissue factor (TF)in the blood and urine in patients with type 2 diabetic nephropathy (DN),and investigate its related clinical significance.Methods A total of 120 DN patients were collected and divided into 3 groups according to urinary albumin and creatinine ratio:normal albuminuria group (＜3.4 mg/mmol) with 64 cases,microalbuminuria group ( ≥3.4 mg/nunol,and ＜ 34.1 mg/mmol) with 35 cases and macroalbuminuria group (≥34.1 mg/mnol) with 21 cases.Twenty healthy persons were enrolled as control group.The expression of monocytes TF in peripheral blood was detected by flow cytometric analyzer.The expression ofTF in the blood and urine was detected by ELLSA.The prcoagulant activity of TF was detected by one-stage coagulation.Results The expressions of monocytes TF in normal albuminuria group,microalbuminuria group and macroalbuminuria group [ (4.32 ± 1.25 )％,(5.01 ± 1.73)％,( 1 1.83 ± 2.14)％ ] were significantly higher than that in control group [(0.84 ± 0.36)％ ](P ＜0.01).TF procoagulant activity in normal albuminuria group,microalbuminuria group and macroalbuminuria group [ ( 64.3 ± 21.2),( 67.1 ± 17.3 ),( 113.8 ± 44.4)mU/L] were obviously higher than that in control grouP [ (23.8 ± 16.4) mU/L](P＜ 0.01 ).The expression of monocytes TF in normal albuminuria group and microalbuminuria group had no statistical significance (P＞0.05),while the expression in macroalbuminuria group had significant difference compared with that in normal albuminuria group and microalbuminuria group (P ＜ 0.01 ).The expression of TF in the blood and urine of DN patients was obviously higher than that of control group (P ＜ 0.01 ).The expression of TF in the blood was positively correlated with that in urine (r =0.684,P ＜ 0.01 ).Conclusions The expressions of TF in the blood and urine in DN patients increase and its procoagulant activity enhances.The expression level of TF has a closed relationship with the increase of albuminuria.

Objective To observe the method of mechanical ventilation in the chest compressions during cardiopulmonary resuscitation (CPR),and to explore the influence of the flow pattern selection of square-wave and decelerating-wave on airway pressure of patients. Methods A prospective self-pairing study was conducted. Forty patients undergoing CPR admitted to Department of Emergency of Lishui City Central Hospital from January 2011 to February 2013 were enrolled. Using Respironics Eisprit ventilator,the working mode and parameters of ventilator were set reasonably according to previous research,while the chest compressions was performed in a stable state by the same doctor,. Each patient received different flow,waves,including square-wave and decelerating-wave,and the highest peak airway pressure was recorded as a pair of data when the time-pressure and time-flow waveform were frozen. Two pairs of data by different doctors were collected in each patient. Eighty pairs of data from 40 patients were collected for statistical analysis by paired t test. Results The highest peak airway pressure of decelerating-wave was (38.15± 5.99)cmH2O (1 cmH2O=0.098 kPa),which was (5.71±1.98)cmH2O lower than that of square wave 〔(43.86± 6.68)cmH2O〕with significantly statistical difference(t=22.010,P=0.000). 73.75%patients undergoing square wave with peak airway pressure over 40 cmH2O were found,but only 45.00% patients were found in decelerating-wave. Conclusion Because decelerating-wave used in mechanical ventilation during CPR can obviously reduce the peak airway pressure,the occurrence of barotrauma,and the probability of triggering high pressure ventilator alarm,and improve the compliance of ventilator,so decelerating-wave is more reasonable than square-wave.
