Objective To evaluate the diagnostic value of velocity parameters of Tardus-Parvus for the detection of renal artery stenosis ( RAS) ( diameter reduction ≥50%) and to determine the useful cutoffs for these parameters .Methods A study group was composed of 221 renal arteries that were detected Tardus-Parvus by color Doppler flow imaging and were referred to abdomino-aorto-re-nal arteriography afterwards .Five Doppler parameters including the peak systolic velocity ( PSV ) , end-diastolic minimum velocity (EDV), resistance index (RI), acceleration time (AT), and accelerated velocity (AC) from each location including renal aorta ( MRA) , segmental artery ( SRA) , interlobar artery ( IRA) , and arcuate artery ( ARA) were archived and compared among the differ-ent groups .Renal artery angiography showed arterial canon reduced 50% or higher RAS .Arteries were considered stenosed on renal arteriography if there was a diameter reduction of greater than 50%.Statistical analysis to determine the best parameter for predicting a RAS was performed with the receiver operating characteristic ( ROC) curves.The sensitivity, specificity, and negative and positive predicting values at various cutoffs were calculated .Results Renal artery stenosis degree was less than 50% in 16 cases, 50%~99%in 197 cases, completely occluded in 2 cases, and no stenosis in 6 case by renal arteriography .For RAS with inner diameter re-duction of 50%or more, the ROC curve analysis showed renal artery flow velocity had a good sensitivity and specificity , 50%~99%of the RAS had optimal threshold value in PSV 20 cm/s, EDV 10 cm/s, RI 0.50, AT 0.09 s, and AC 1.5 m/s2.Conclusions Tardus-Parvus had high specificity and sensitivity for diagnosis of stenosis rate in more than 50% of the RAS, low sensitivity for the narrow degree in 0~49%, and no clinical value for the renal artery occlusion .

Objective To investigate the prognostic value of arterial blood lactate(Lac) and lactate clearance rate(LCR) for severe neonatal asphyxia.Methods One hundred and fifteen cases of severe neo natal asphyxia admitted in NICU of our hospital from January 2011 to October 2014 were retrospectively analyzed.Lac and LCR values were measured at multiple time points and were compared between those died (27 cases,the death group) and those survived (88 cases, the survival group).The correlation between prognosis and Lac as well asLCR was investigated.Receiver operating characteristic(ROC) curves were drawn to evaluate the prognostic value of Lac and LCR at different time points.Results No significant differences in initial lactate levels and neonatal critical illness score (NCIS) were detected between the two groups (P ＞0.05), while Lac and LCR values at 1 h,2 h,and 6 h showed significant differences between the two groups (P ＜ 0.05).The low-LCR group showed a higher rate of multiple organ dysfunction syndrome and mortality rates than the high-LCR group (44.64％ vs.15.25 ％, P =0.001;32.14％ vs.15.25 ％, P =0.033, respectively).Post-treatment Lac level was positively correlated with prognosis, while LCR at 1 h,2 h, and 6 h were negatively correlated with prognosis.Areas under curve of Lac ROC at 1 h,2 h, and 6 h were 0.625,0.719,and 0.835 respectively, while areas under curve of LCR ROC at 1 h, 2 h, and 6 h were 0.676,0.784, and 0.898 respectively.Conclusion Low LCR for severe neonatal asphyxia predicts poor prognosis.Lac level and LCR at 6 h after emergency treatment is a prognostic indicator for severe neonatal asphyxia.

Objective To explore the clinical significance of the coagulation and fibrolysis parameters changes for the knowledge of complicated thrombosis after chemotherapy in malignant lymphomas. Methods Morning fasting anti-coagulation blood samples were taken to detect plasma prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen (FIB) and thrombin time (TT) with automatic coagulation analyzer in 71 hospitalized malignant lymphomas and 20 normal controls. The plasma D-dimer levels of the two groups were detected with immunoturbidimetry. Results The levels of plasma APTT, Fib and D-dimer in 71 malignant lynphomas were (30.44±1.43) s, (3.28±0.20) g/L, (297.05±56.59) μg/L respectively, which were significantly higher than those in normal controls at the levels of (23.72±0.76) s, (2.57±0.22) g/L, (94.50±26.07) μg/L respectively (P ＜0.05). The coagulation and fibrolysis parameters were of no statistic differences between the normal controls and lymphomas of stage Ⅰ and Ⅱ (P ＞0.05). The APTT and Fib levels in lymphomas of stage Ⅲ and Ⅳ were higher than those in normal controls and lymphomas of stage Ⅰ and Ⅱ (P ＜0.05). There are 7 malignant lymphomas complicated venous thrombosis . Of the 7 cases, the FIB and D-dimer levels were higher than those of stage Ⅰ and Ⅱ, furthermore the D-dimer levels were higher than those of stage Ⅲ and Ⅳ. Conclusion The abnormalities of coagulation and fibrolysis parameters occurred in malignant lymphomas with requirement of periodic monitoring. After chemotherapy, the lymphoma patients had a high incidence of venous thrombosis, which need early prevention for prolongation of the survival.
