ABSTRACT
Objective To establish children's independent normal reference intervals of five coagulation indexes in Chongqing,in order to better provide references for clinic.Methods The plasma samples of 5 119 healthy children were collected and used to detecting prothrombin time (PT),activated partial thromboplastin time (APTT) and fibrinogen (FIB),thrombin time (TT) and D-Dimer (D-D) via Sysmex CS5100 and Sysmex CSA2000.According to ages,the children were divided into 6 groups:newborn (at 0 to less than 15 days of age),newborn (at 15 days to less than 1 month of age),infant (at 1 to less than 7 months of age),children (at 7 months to less than 3 years of age),children (at 3 to less than 7 years of age),children (at 7 to 15 years of age),and comparatively analysed.For normal distribution data,(x)± 1.96s was used to calculate the reference intervals;while for skewness distribution data,the reference intervals was calculated by 95 ％ reference interval according to the percentile of P2.5 and P97.5.Results The normal reference intervals of five coagulation indexes in this clinical laboratory were as follows:PT 11.1-20.2 s (at 0 to less than 15 days of age),10.7-15.8 s (at 15 days to less than 1 month of age),9.9-13.5 s (at 1 month to 15 years of age);APTT 28.8-91.6 s (at 0 to less than 15 days of age),33.3-64.2 s (at 15 days to less tha 1 month of age),24.0-53.2 s (at 1 to less than 7 months of age),21.2-39.2 s (at 7 months to less tha 15 years of age);FIB 1.45-3.52 g/L (at 0 to less than 3 years of age),1.50-3.52 g/L (at 3 to 15 years of age);TT 15.4-26.3 s (at 0 to less than 15 days of age),14.9-21.4 s (at 15 days to less than 7 months of age),14.7-20.1 s (at 7 months to less than 3 years of age),14.9-19.3 s (at 3 to 15 years of age);D-D 0.1-5.1 mg/L (at 0 to less than 15 days of age),0.2-2.2 mg/L (at 15 days to less than 1 month of age),0.1-1.1 mg/L (at 1 to less tha 7 months of age),0.1-1.4 mg/L (at 7 months to less than 3 years of age),0.1-1.3 mg/L (at 3 to less than 7 years of age),0-1.0 mg/L (at 7 to 15 years of age).Conclusion The normal reference intervals of five coagulation indexes,including PT,APTT,FIB,TT and D-D,are established,which provide more accurate references for the diagnosis of related diseases in infants and children in this area.
ABSTRACT
Objective To investigate cause and prevention of dysuria after hyperplasia of prostate operation. Methods To analyze 66 cases of dysuria after hyperplasia of prostate operation retrospectively. Result The most common reasons to dysuria are orderly stenosis of bladder neck; inflammatory edema of bladder neck; urethral stricture; rehyperplasia of remained prostate tissue; neruogenic bladder; prominence of ureteral crest; clot obstruction. Conclusion Prevention of dysuria after hyperplasia of prostate operation consists in preoperative satisfied diagnosis and correct treatment in operation and after operation.
