Objective To observe the anticoagulant effect of low molecular weight heparin on induced hemodialysis in patients with acute renal failure.Method One hundred and eight patients with acute renal failure treated with induced hemodialysis were randomly divided into low molecular weight heparin(LMWH)group and unfractionated heparin(UFH)group.A bolus disc of UFH was given at first and then maintained by continuous infusion in UFH group,whereas a single bolus dose of LMWH with 2000AFXa IU to 4000AFXa IU in LMWH group.Results Anticoagulant effect between LMWH and UFH did not show significant discrepancy during induced hemodialysis.The bleeding from internal jugular vein catheter increased in the UFH group much more than that in the UFH group was significantly higher than that in the LMWH group.Anti-FXa blood levels were significantly higher in LMWH group than in UFH group.Conclusions LMWH has minor influence on aPTT and TT,while its anticoagulation effect approximates to that of UFH.LMWH represents a realistic alternative agent UFH in acute renal failure induced hemodialysis.

The phytase was extracted from solid state leavening of Trichoderma Viride LH374.The crude product was purified by(NH_4)_2SO_4 precipitation,gel filtration and ion exchange chromatography.The purified phyatse was 13.3 times of the raw products,and the extraction ration was 27.1%.The study on the enzymology of phyatse showed that the optimal temperature and pH were 55℃ and 6.0,respectively.The Km value of the phytase was 0.15mmol/L.

Objective To determine the levels of plasma histamine and oxidative status in patients with dermatographism before and after the treatment with anti-histamine drugs. Methods Totally, 85 patients with dermatographism were randomly divided into two groups to receive oral desloratadine and cetirizine respectively for 4 weeks. Enzyme linked immunosorbent assay (ELISA) was performed to detect the plasma level of histamine, superoxide dismutases (SOD), glutathion peroxidase (GSH-PX) and malondialdehyde (MDA) in all the patients before and after the treatment and in 15 normal human controls. The efficacy of desloratadine and cetirizine for dermatographism was estimated. Results The response rate was 83.72% and 78.57% in patients treated with desloratadine and those with cetirizine, respectively (x2 = 0.369, P> 0.05). The untreated patients with dermatographism showed an elevation in the plasma level of histamine (3.87 ± 1.21 ng/ml vs. 1.76 ± 0.56 ng/ml, P< 0.05) and MDA (3.86 ± 1.03 nmol/ml vs. 2.19 ± 0.82 nmol/ml, P< 0.05), but a decline in the activity of SOD (86.29 ± 19.9 U/ml vs. 112.12 ± 27.88 U/ml, P< 0.05) and GSH-PX (74.52 ± 47.67 vs.915.06 ± 115.96, P< 0.05) compared with the normal human controls. The treatment with antihistamine induced a reduction in the plasma level of histamine (1.61 ± 0.47 ng/ml vs. 3.87 ± 1.21 ng/ml, P< 0.05) and MDA (2.65 ± 0.77 nmol/ml vs. 3.86 ± 1.03 nmol/ml, P< 0.05), but an increment in the activity of GSH-PX (921.46 ± 157.37 vs.74.52 ± 47.67, P < 0.05) with no changes of SOD in patients with dermatographism. Conclusions In patients with dermatographism, plasma histamine is increased and there is an imbalance of oxidation-antioxidation.Desloratadine and cetirizine are effective for the treatment of dermatographism.

Objective To investigate the value of automatic spectral imaging mode selection and adaptive statistical iterative reconstruction(ASIR) in upper abdominal enhanced CT with low contrast agent dose, and to optimize the combination of monochromatic energy level and ASIR percentage.Methods 100 patients underwent upper abdominal enhancement CT were randomly assigned into control group (n=50) and study group (n=50).In the control group, tube voltage of 120 kVp and contrast medium of 450 mg I/kg were used with the images reconstructed using 40% ASIR.In the study group, CT spectral imaging with automatic spectral imaging mode selection and contrast medium of 300 mg I/kg were used,and monochromatic images (40-65 keV,intervals of 5 keV) were reconstructed using 40%-60% ASIR (intervals of 10%), respectively.CT value, image noise and contrast-to-noise ratio of the liver, pancreas, aorta and portal vein and radiation dose were compared using two independent samples t test.Overall image quality was assessed by Mann-Whitney U test.Results All image quality indexes in 60 keV with 40% ASIR, 55-60 keV with 50% ASIR in the study group were equal to or better than the control group.There was no significant difference in radiation dose between control group and study group.Conclusion Combined automatic spectral imaging mode selection with ASIR, upper abdominal enhanced CT with low contrast agent dose could improve image quality compared to 120 kVp with 40% ASIR, without increasing radiation dose.

Objective To present the baseline characteristics of serum uric acid level in patients with chronic kidney disease(CKD)in single.centre nephrology clinic and judge the risk factor for decreased renal function of CKD Datients.Methods A cross-sectional study on CKD patients in clinic was carried out for 9 months.Results 780 CKD cases were enrolled in the study.The top four causes of CKD in these patients were primary glomerular disease(59.0%),essential hypertension(7.6%),lupus nephritis(6.4%)and diabetic nephropathy(6.3%).The average age was 41.9.The distribution of CKD stage was 47.8%of CKD1,18.7%of CKD2,14.0%of CKD3,8.1% of CKD4 and 11.4%of CKD5.Multivariate Logistic regression regression analysis indicated that age,proteinuria,hypertension were independently correlated with decreased renal function.Conclusion This is the largest cross-sectional study of CKD in China,which will help to determine the basic status of Chinese CKD patients,laying a basis for further followup.

Objective To present the baseline characteristics of serum uric acid level in patients with chro-nic kidney disease(CKD). Methods A cross-sectional study on CKD patients was carried out in our hospital for 9 months. Results 713 patients were enrolled. The top three causes of CKD in these patients were primary glomerular disease(61.2%, 436/713), essential hypertensive kidney disease (7. 2%, 51/713 ) and diabetic nephropathy (5.8% ,41/713). Serum uric acid level and the incidence of hyperuricemia were associated with the stage of CKD (F = 73. 569, P = 0. 000;χ2= 138. 156, P = 0.000). A significantly negative correlation was discovered between ser-um uric acid level and the level of glomerular filtration rate(RR = - 1. 045 ,P =0. 000). A significantly positive cor-relation of serum uric acid level was found with diastohc blood pressure, proteinuia level, smoking and BMI ( RR = 1.400,15. 149,37. 696,and 3.421 ,P <0.05 ,respectively). Conclusions The cross-sectional study of serum uric acid level in patients with CKD will help to determine the dynamic changes of serum uric acid level in Chinese CKD patients and lay a solid basis for the prevention and treatment of CKD and its complications.

To analyse the relationship between tumor necrosis factor (TNF)-α and interleukin-6 with hyperuricemia in ethnic Uygur,Kazak,and Han in Xinjiang province.1 200 cases of Uygur,Han,and Kazak populations were randomly enrolled.Serum uric acid,triglyceride,total cholesterol,high density lipoprotein-cholesterol,low density lipoprotein-cholesterol,fasting plasma glucose,body weigh and height,waist circumference,and hip circumference were measured.Waist-to-hip ratio and body mass index were calculated,and TNF-α,interleukin-6 were determined.The differences between uric acid and inflammatory factors were statistically significant; The differences in TNF-α was statistically significant between high uric acid group and control group in Uygur and Han,and the differences in interleukin-6 was statistically significant between high uric acid group and control group in Uygur,Kazak,and Han(P＜0.01).TNF-α and interleukin-6 were positively correlated with serum uric acid in Uygur,but in Kazak only interleukin-6 was negatively correlated with serum uric acid,in Han only interleukin-6 was positively correlated with serum uric acid(P ＜ 0.01).Hyperuricemia was associated with inflammatory factors,TNF-α,interleukin-6,but there were ethnic differences among Uygur,Kazak,and Han,thus it may provide people of new ideas for prevention and treatment of hyperuricemia and other related metabolic disorders.
