Objective To analyze the validity of Caprini venous thrombosis risk assessment model (Caprini RAM) in the tunneled cuffed dialysis catheters (TCCs) dysfunction patients with central venous thrombosis (CVT).Methods A total of 187 maintenance hemodialysis patients with TCCs dysfunction admitted to West China Hospital of Sichuan University from January 2013 to September 2016 were analyzed retrospectively.According to the chest computed tomography venography results,patients were divided into CVT group and non CVT group.Their general clinical data (age,gender,primary diseases,history of dialysis access,etc.),blood biochemical data (hemoglobin,serum albumin,blood lipid,etc.) and 40 risk factors of Caprini RAM were collected.Caprini RAM scores were computed for risk stratification of thrombosis.Two groups were compared to analyze the value of Caprini RAM in these patients by statistics.Results One hundred and twenty CVT patients and sixty-seven non CVT patients were enrolled.In CVT group the duration of dialysis,hemoglobin and hematocrit were higher than those in non CVT group (all P < 0.05).There was no significant difference between the two groups in gender,age,primary diseases,duration of catheter dependence,catheter tip position,usage of urokinase (all P > 0.05).The average score of Caprini RAM in CVT group and non CVT group did not show statistical difference (6.23+ 1.81 vs 6.19+ 1.95,P=0.913).All patients were stratified into higher risk level and highest risk level according to Caprini RAM.Higher risk level patients accounted for 18.18% and highest risk level patients accounted for 81.82%.As patients with inequable Caprini RAM scores,their incidence of CVT did not differ statistically (x2=0.105,P=0.746).CVT incidence rate of higher risk level patients was 61.76%,and of highest risk level patients was 64.70%.Conclusions Caprini RAM verifies that maintenance hemodialysis patients with TCCs dysfunction have high risk of venous thrombosis,but this model fails to distinguish patients between CVT group and non CVT group.Its clinical diagnosis is relatively limited and needs to be further explored.

Objective To explore the relationship of GFAP, NDKA and PARK7 serum concentrations of patients with IS, and their diagnose and prognosis value in IS. MethodsThe serum concentrations of GFAP, NDKA and PARK7 were detected in 37 IS patients, 28 ICH patients and and 30 healthy persons by ELISA. These indexes of patients were detected in 12 hours, 3 d and 14th day after onset of ischemic stroke. Their neurological injury status were also evaluated by MESSS at corresponding time points, and their activities of daily living were evaluated by BI at 14 d discharge from hospitaL At the same time, the diagnostic efficiency was analysed for IS using the three biomarkers and the combined detection. ResultsIn IS group, the serum concentrations of GFAP in 12 hours, 3rd and 14th day after onset were (5. 49 ±2. 25 )μg,/L, (5. 17 ± 2. 29) μg/L and (5. 96 ± 2.39 ) μg/L, respectively. The serum concentrations of NDKA were 9. 15(6.28 -12.79) μg/L, 9. 13(6.31 - 12.23) μg/L, 9.31(6.40 - 11.83) μg/L respectively,and the serum concentrations of PARK7 were (32. 71 ±6. 34 ) μg/L, (31.23 ±6. 04) μg/L, (32. 79 ±6. 94) μg/L respectively. The serum levels of GFAP, NDKA and PARK were respectively (4. 62 ± 1. 56)μg/L, 4. 24(3. 30 -5. 61 ) μg/L, ( 14. 25 +2. 65) μg/L in healthy control group. The levels in IS groups were remarkably increased compared with the healthy control group except the level of GFAP in the 3rd day (t = 1. 129, P>0. 05). The levels in other time points were significantly different between patients group and healthy control. t value of GFAP were respectively 2. 642, 1. 870,P<0. 05; Z value of NDKA were 6. 173, 6.100, 6.278,P <0. 01; t value of PARK7 were 14.964, 15.367,16.060, P <0. 01. The specificity and sensitivity of the individual detection for diagnosis of IS was 46. 7% (14/30) and 81.1%( 30/37 ) for GFAP, 90. 0% ( 27/30 ) and 78.4% ( 29/37 ) for NDKA, 96. 7% (29/30) and 97.3% ( 36/37 )for PARK7. The specificity and sensitivity for combined detection of 3 biomarkers was 96. 7% (29/30) and 100% (37/37). The combined detection achieved better specificity and sensitivity. Moreover, the risk of IS with higher level GFAP was 1. 3 times that of the controls ( OR = 1. 300, P = 0. 044 ). The risk of higher NDKA was 1.7 times higher( OR = 1. 668, P = 0. 036 ). The risk of higher PARK7 was 1.8 times higher (OR = 1. 809, P =0. 005 ). The serum levels of GFAP were significantly different between IS and ICH in 12 h(t= 4.097, P=0.000). The serum concentrations of GFAP, NDKA and PARK7 were positively correlated with MESSS score at different time points. In IS, r value were 0. 534, 0. 482, 0. 357 , P < 0. 05at less than 12 h; r value were 0.433, 0.487, 0. 299,P value were 0. 007, 0. 002, 0.073 at 3 d;r value were 0. 394, 0. 200, 0. 084,P value were 0.016, 0. 236, 0.620 at 14 d. And the serum levels of GFAP,NDKA and PARK7 were negatively correlated with BI score at 14th day, r value were -0. 430, -0. 321,-0.076,P value were 0.044,0.050,0.657. Conclusions The concentrations of GFAP, NDKA and PARK7 in serum are closely related with IS. The increased seruro levels of these indexes are risk factors in IS. The detection of these indexes could be helpful for the early diagnosis, timely treatment and prognosis assessment for IS.
