To investigate the application of improved radial arteryand cephalic vein anastomosis in the fistulation for the hemodialysis in patients, 80 cases of patients with chronic renal failure were randomly divided into two groups, a control group and an improved group. The procedure for the wrist radial arteryand cephalic vein anastomosis was improved, in which in a way of continuously everted full-thickness suture, the distal end of radial artery and the proximal end of cephalic vein were anastomosed. The patients were examined by the different methods before the surgery to evaluate the patients’conditions. Patients in the improved group underwent the anastomosis of the wrist radial artery and cephalic vein in a way of continuously everted full-thickness suture, and those in the control group underwent the anastomosis in the conventional way. The improved procedure showed some advantages, such as reduced anastomotic blood leakage, good alignment of the arteryand veinwalls, shortened vascular suture time, and less knot of sutures at the anastomotic junction. The improved procedure should be appropriated for the patients whose Allen's test is negative and cephalic vein is good in the blood flow and filling. However, the weak blood reflux of the distal end of radial artery should bethe contraindication for the improved procedure.

Introduction: Blood flow restriction training can be used as an alternative to conventional exercise in chronic kidney disease patients with indication of arteriovenous fistula. Objective: Evaluating the efficacy of blood flow restriction training in the diameter and distensibility change of the cephalic vein and the diameter and flow of the radial artery, muscle strength and forearm circumference in chronic kidney disease patients with arteriovenous fistula pre-creation. Methods: A blind randomized clinical trial consisting of 26 chronic kidney disease patients allocated into a blood flow restriction training group (blood flow restriction; n = 12) and a group without blood flow restriction training (control group; n = 14). Blood flow restriction was performed at 50% of systolic blood pressure and using 40% of handgrip strength as load for the isometric exercises in both groups. Results: An increase in the diameter of the cephalic vein in the 2 cm (p = 0.008) and 10 cm segments (p = 0.001) was observed in the control group. The diameter of the radial artery increased in all segments in the blood flow restriction group (2, 10 and 20 cm; p = 0.005, p = 0.021 and p = 0.018, respectively) and in the 10 and 20 cm segments (p = 0.017 and p = 0.026) in the control group. Handgrip strength only increased in the control group (p = 0.003). Conclusion: Physical training associated with blood flow restriction increased cephalic vein diameters in both groups and was effective in increasing the diameter of the radial artery; however, it did not demonstrate superiority over the exercise group protocol without blood flow restriction.

This paper proposes a study on the effect of hybrid blood purification therapy based on camel nanoantibody immunoadsorbent on chronic renal failure patients in nephrology department. In this paper, the hybrid blood purification therapy based on camel nanoantibody immunoadsorbent was applied to patients with chronic renal failure, and the curative effect of the patients was studied. In order to highlight the effect, a control group was set up for comparison. In this paper, the clearance effect of small molecule toxin, middle molecular toxin, and dialysis adequacy was analyzed. This study found that the average dialysis adequacy of the control group was 1.23% and that of the experimental group was 1.26%. The dialysis adequacy of the experimental group was significantly better than that of the control group. In addition, the clearance effect of small and medium molecular toxins in the experimental group was significantly better than that in the control group. It can be seen that the hybrid blood purification therapy based on camel nanoantibody immunoadsorbent is effective in the treatment of chronic renal failure patients in the department of nephrology. Therefore, it is of great value to apply camel nanoantibody in the clinical treatment of renal failure.

1. The influence of dietary sodium intake on the glomerular filtration rate (GFR/nephron) and potassium and phosphate excretion was examined at three stages of progressive chronic renal failure produced in rats by sequential partial nephrectomies. 2. The adaptive increased sodium excretion per nephron in the control group receiving a constant sodium intake did not occur in the experimental group that had a gradual reduction of dietary sodium in direct proportion to the fall in GFR. 3. Despite the difference in sodium excretion, the increase in GFR/nephron, the daily variation in the amount of potassium and phosphate excreted, the increase in potassium and phosphate excretion per unit nephron, and the plasma potassium and phosphate concentrations were the same in the two groups. 4. The concept of ‘autonomous adaptation’ in chronic renal failure is presented.

Introduction: Cardiovascular diseases (CVD) are known as important reasons of the increased morbidity and mortality observed in patients with chronic renal failure (CRF). The association of serum Interlukin-6 , homocysteine as well as other cardiovascular risk factors in relation to existence and cause of CVD were investigated. Method: In this study 200 CRF patients were recruited and further stratified into group with Male and Female as case groups. Those without renal failure were assigned as control group (n=200). Results: The patients with CRF showed a significant increase in plasma levels of Cpk-MB homocysteine and C-reactive protein (CRP) compared to control. The positive association were observed between homocysteine, Urea and Hs-CRP, IL_6 . It shows a significant Association of parameters in CRF . Conclusion: The results demonstrated elevation in plasma values IL-6 , homocysteine and HS-CRP in patients with CRF . However, these modifications may be lead to atherosclerosis and consequence CVD event. These parameters may be important with respect to the high morbidity and mortality of CVD found in patients with CRF.

Although the kidney is believed to play a minor role in bile acid (BA) excretion, chronic renal failure (CRF) has been reported to be associated with increased serum bile acid levels and alterations in BA homeostasis. The mechanisms for elevated BA levels are poorly understood in both clinical and experimental studies. This study was designed to examine the effects of naturally progressing CRF of longer duration on the hepatic and renal mRNA and protein levels of the BA-synthesizing enzyme Cyp7a1 and the BA transporters Ntcp, Bsep, Mrp3, Ost-α, and Ost-β. Sprague-Dawley rats were randomized to the CRF group (⅚ nephrectomy) or to the sham-operated control group and were analyzed 8 wk after surgery. Results obtained in the CRF rats were compared with those obtained in rats that had undergone uninephrectomy (UNX). The CRF group exhibited significantly increased plasma cholesterol and BA concentrations. Hepatic Cyp7a1 mRNA and protein levels were almost identical in the two groups. Hepatic Mrp3, Ost-α, and Ost-β expression was increased, suggesting increased basolateral efflux of bile acids into the blood. However, no such changes in BA transporter expression were observed in the remnant kidney. In UNX rats, similar changes in plasma BA levels and in the expression of BA transporters were found. We hypothesize that the increase in plasma BA is an early event in the progression of CRF and is caused by increased efflux across the basolateral hepatocyte membrane.

ABSTRACT: Kidney disease that affects bitches with pyometra may lead patients to develop chronic renal failure even after pyometra treatment. Therefore, several studies have sought to clarify the gaps in the understanding of the pathogenesis of renal injury in pyometra. Identification of early detection markers for renal damage, which can predict and identify the prognosis of the disease, is very important. Proteinuria analysis can diagnose kidney damage, since proteins such as albumin are not filtered through the glomerulus and those that undergo glomerular filtration are almost completely reabsorbed by tubular cells. The objective of this study was to evaluate whether the urinary protein-to-creatinine ratio (UPC) can detect renal injury in bitches with pyometra before development of azotemia. For this, 44 bitches with pyometra were divided into two groups: bitches with azotemic piometra (A, n=15, creatinine >1.7) and bitches with non-azotemic pyometra (NA, n=29). The two groups were compared to the control group (CG, n=12), which had no signs of systemic disease. All animals underwent blood and urine tests. Leukocytosis was more evident in bitches in the A group than in the other groups. This shows that the inflammatory response may be associated with the pathogenesis of renal injury. The median UPC in bitches with pyometra was significantly higher than in the CG, with a median above the reference values. In conclusion, the UPC can be used in bitches with pyometra to detect renal damage before the development of azotemia. It has been suggested that the UPC of bitches with pyometra should be followed through during the postoperative period so that permanent renal lesions secondary to pyometra can be diagnosed and treated properly before the development of azotemia.

Background. Chronic renal failure (CRF) has become a global health problem and bears a huge economic burden. FuShengong Decoction (FSGD) as traditional Chinese medicine has multiple pharmacological effects. Objectives. To understand the underlying molecular mechanism and signaling pathway involved in the FSGD treatment of CRF and screen differentially expressed proteins in rats with CRF treated with FSGD. Methods. Thirty-three male Sprague-Dawley rats were randomly divided into control group, CRF group, and FSGD group. Differentially expressed proteins were screened by iTRAQ coupled with nanoLC-MS/MS, and these identified proteins were later analyzed by GO, KEGG, and STRING. Additionally, haptoglobin (HP) and alpha-1-antitrypsin (AAT) were finally verified by ELISA, Western blot, and real time PCR. Results. A total of 417 proteins were identified. Nineteen differentially expressed proteins were identified in the FSGD group compared with the model group, of which 3 proteins were upregulated and 16 proteins were downregulated. Cluster analysis indicated that inflammatory response was associated with these proteins and complement and coagulation cascade pathways were predominantly involved. The validation methods further confirmed that the levels of HP and AAT were significantly increased. Conclusions. HP and AAT may be the important biomarkers in the pathogenesis of CRF and FSGD therapy.

Abstract: Uric acid is the final product of purine metabolism in humans. It was determined that this compound has important antioxidative properties and it may be oxidized to allantoin by various reactive oxygen species. Therefore, the measurement of allantoin may be useful for the determination of oxidative stress in humans.: We measured allantoin and uric acid in human plasma and erythrocytes obtained from patients with chronic renal failure before hemodialysis (n=30) and blood donors (n=30). We used a method based on selective isolation of allantoin from deproteinized plasma and erythrocyte lysate samples on AG 1-X8 resin and its derivatization to glyoxylate-2, 4-dinitrophenylhydrazone. Separation of glyoxylate-2, 4-dinitrophenylhydrazone from interfering substances was achieved on reversed phase HPLC with gradient elution and UV/VIS detection at 360 nm. Uric acid was determined by reversed phase HPLC with UV/VIS detection at 292 nm.: We found significant differences in allantoin and uric acid concentration between the patients with chronic renal failure and the control group both in plasma (20.5±6.5 μmol/L and 323.9±62.9 μmol/L vs. 2.1±1.1 μmol/L and 270.1±62.3 μmol/L, p<0.05) and erythrocytes [82.8±39.1 nmol/g hemoglobin (Hb) and 110.7±28.8 nmol/g Hb vs. 20.1±6.1 nmol/g Hb and 82.1±23.7 nmol/g Hb, p<0.05].: Significant higher levels of allantoin in both plasma and erythrocytes of patients with chronic renal failure indicate that allantoin may be used as a good marker of oxidative stress.Clin Chem Lab Med 2008;46:1270–4.
