Objective To explore the effects of cognitive impairment on the self-management ability and self-management behavior among the patients of end stage renal disease (ESRD) with maintenance hemodialysis (MHD).Methods 134 MHD patients were divided into the non cognitive impairment group(62 subjects) and cognitive impairment group(72 subjects) according to Montreal cognitive assessment (MoCA)scores,to asses and analyze the level of hemodialysis knowledge,hemodialysis adherence,self-management ability and self-management behavior between the two groups.Results The rates of hemodialysis skipping behavior and the rates of hemodialysis shorting behavior in cognitive impairment group (respectively,18.06％,22.22％) were higher than that in non cognitive impairment group(respectively,6.45％,8.06％) with significant difference (x2 =4.0495,5.0526,all P＜0.05).The cognitive impairment group had significantly less total score (respectively,16.62 ± 1.99,51.32± 9.92,56.99±8.3) in the level of hemodialysis knowledge,the self-management ability and the self-management behavior compared with the non cognitive impairment group(respectively,18.48±2.03,63.69±10.16,78.54± 10.28) (t=5.3448,7.1172,13.4140,all P＜0.05).Conclusion Cognitive impairment can produce an effect on the level of hemodialysis knowledge and hemodialysis adherence.Cognitive impairment can also reduce the function of self-management ability and self-management behavior and make badly further effect on curative effect of hemodialysis.

ObjectiveTo evaluate the application of quantitative sensory testing(QST) in hemodialysis (HD) patients with peripheral neuropathy.MethodsThe values of the quantitative sensory testing and sensory conduction velocity at different locations of extremities in 40 cases of the HD patients and 40 normal persons were recorded.ResultsAccording to the control group,without symptoms group and with symptoms group,the thermal threshold(TT) and vibratory threshold (VT) at the four different locations of extremities were increased,thresholds of the later two groups were significantly higher than those of normal controls (P ＜ 0.05 ).Especially finger warm and vibratory thresholds,hypothenar heat pain thresholds,instep heat pain and vibratory thresholds,calf cold pain and vibratory thresholds were significantly difference between with symptoms group and normal control group (P＜0.01 ).Finger cool and warm thresholds,instep heat pain thresholds,thresholds of calf warm,cold pain and heat pain,and vibratory thresholds at the four different locations of extremities were significantly difference between wthout symptoms group and with symptoms group (P＜ 0.05).The SCV values of the median nerve,tibial nerve and lateral popliteal nerve were significantly difference between HD patients group and normal control(P ＜0.05 ).The total abnormal rate of QST was 65％,with symptoms group was 77.27％,total abnormal rate of SCV was 55.0％,with symptoms group was 68.18％.The total abnormal rate of QST were significantly higher than those of SCV (P＜0.01 ).ConclusionQST is a sensitive method for diagnosis of uremic neuropathy.

Objective To evaluate pigtail catheter mashing thrombosis combined with catheter directed thrombolysis in the treatment of acute iliofemoral venous thrombosis complicated by Cockett syndrome in the left lower limbs.Method Data of 137 cases of acute iliofemoral venous thrombosis complicated with Cockett syndrome in left lower limb by interventional therapy from January 2007 to October 2012 were analyzed retrospectively.Inferior vena cava filters were placed in all of the patients.Patients were divided into two groups:Group A (n =81) treated with catheter directed thrombolysis only,Group B (n =56) treated with pigtail catheter mashing thrombosis combined with catheter directed thrombolysis.After operation,patients were treated by anticoagulation with urokinase and heparin calcium,and then warfarin for 6 to 1 2 months.Results The thrombolysis time in group B was significantly shorter than that in group A (P ＜0.01),the dosage of urokinase was significantly less than that in group A(P ＜ 0.01).The venous patency score in group B after therapy was significantly better than in group A (P ＜ 0.01).121 patients were followed up for 10-60 months.There were no pulmonary embolism.Conclusions Pigtail catheter mashing thrombosis combined with catheter directed thrombolysis in the treatment of acute iliofemoral venous thrombosis complicated with Cockett syndrome in left lower limb can improve thrombolytic efficiency,shorten thrombolysis time,reduce the use of urokinase.

Objective:To evaluate the technical aspects and examine patency rates of stent placement across the inguinal ligament for managing long-segment iliac venous obstruction.Methods:From Jan 2012 to Jan 2017, a total of 73 patients (42 cases of post-acute deep venous thrombosis(DVT) thrombolysis and 31 of post-thrombotic syndrome (PTS)) with long-segment iliac venous obstruction were treated with interventional surgery. All patients underwent balloon dilatation and placement of at least two stents extending below inguinal ligament.Results:The technical success rate was 100%. No serious perioperative complications occurred. The mean duration of the procedure in the DVT group was shorter than PTS group(35±12) min vs. (62±12) min, P<0.05). The mean number of stents did not differ between the two groups.Mean follow up periods was 28.34 months. Overall cumulative primary, assisted primary, and secondary stent patency rates were 100%, 100%, and 100% at 6 months and 87.7%, 95.9%, and 100% at 12 months and 75.8%, 85.1%, and 96.3% at 24 months, respectively(all P>0.05). Edema and pain alleviated significantly in the two groups. There was no stents compressed or fractured. Conclusions:Stenting across the inguinal ligament for treatment of long-segment iliac venous obstruction is a safe, effective, and feasible method.
