Hemodialysis / 대한내과학회지

With the widespread availability of dialysis, the lives of end-stage renal disease patients have been prolonged over the past fifty years. Hemodialysis relies on the diffusion of molecules across a semipermeable membrane along the concentration gradient. In addition to diffusion, movement of waste products from the circulation into the dialysate can occur as a result of convective clearance. Use of high-flux dialyzer has increased the removal of the middle molecules such as beta2-microglobulin. Recently on-line hemodiafiltration which combined the hemodialysis and hemofiltration to increase the convective clearance of the large molecules has been available. About the hemodialysis adequacy, the result of hemodialysis (HEMO) study suggests that increasing the dose to greater than a single-pool Kt/Vurea 1.4 does not improve the survival of the patients. While the technical and scientific improvement in hemodialysis has led to a noticeable improvement in the survival of the dialysis patients, cardiovascular mortality and event rates are extraordinarily high in dialysis population. In addition to hemodialysis treatment, nephrologists taking care of dialysis patients must recognize and treat the diverse complications that can result from the loss of kidney function.

Heart protection of L-carnitine in chronic renal failure rats / 中华肾脏病杂志

Objective To investigate the effect of L-carnitine on pathological changes of myocardium and the underlying mechanism in chronic renal failure rats (CRF). Methods A total of 55 male SD rats were randomly divided into sham group (n=10),model group (n=15),low dose (300 mg/kg),medium dose (600 mg/kg) and high dose (900 mg/kg) L-carnitine group(n=10,each).5/6 subtotal nephrectomy was performed in these rats without sham group.One week after the operation,normal saline or corresponding dose L-carnitine were intragastrically administrated to sham and model group or L-carnitine groups for 17 weeks.Transthoracic echocardiography,mean arterial pressure (MAP),heart rate (HR) and heart weight/body weight were assessed.Moreover,24h urine protein,renal function,SOD,MDA,IL-6,ATP,ADP were measured at the end of the study.Additionally,pathological changes in myocardium were detected by light microscope and transmission electron microscope. Results (1) ATP (μmol/g·wt)in L-carnitine groups (2.35±0.24,3.59±0.28,3.78±0.25) was significantly higher than that in model group (1.61±0.12) (all P＜0.01).(2) Thickness of posterior wall of left ventricle (mm) in high dose L-carnitine group was thinner than that in model group (3.74±0.23 vs 4.18±0.48,P＜0.05). (3) The ratios of heart weight to body weight in both medium dose and high dose L-carnitine groups (3.92±0.27,3.65±0.2) were significantly lower compared to model group (3.99±0.27) (all P＜0.01). (4) Under light microscopy,disarrangement and hypertrophy of cardiac myocytes,increased myocardial fibrosis were observed in model group, while these changes and the pathological scores were significantly improved in both medium dose and high dose L-carnitine groups (7.14±1.07,6.13±0.99),as compared with model group (9.88±1.13) (all P＜0.01).Under electron microscopy,typical changes in cardiac hypertrophy were observed,including dissolution of myocardial fibers,increasing and swelling of mitochondria,membrane rupture as well as matrix increase in model group,while these changes were ameliorated by L-carnitine in a dose-dependent manner. (5) Seventeen weeks after the treatment,both IL-6 and MDA were decreased in all L-carnitine-treated groups than those in model group [IL-6 (ng/L):261.86±13.18,240.12±18.7,233.34±36.88 vs 596.64±81.41; MDA (nmol/L):15.23±2.01,12.41±0.6.10.97±1.9 vs 21.84±2.71).Whereas,SOD (U/ml) were increased in L-carnitine-treated groups (51.2±6.11,58.51±5.52,60.63±6.94) than that in model group(32.01 ±5.69 )(all P＜0.05).(6) No significant differences of systolic,diastolic blood pressure or MAP were found among groups. Conclusion L-carnitine can improve energy metabolism,micro-inflammation and oxidative stress in myocardium of CRF rats,which may be associated with the amelioration of cardiac hypertrophy and fibrosis.

Relationship between Chronic Kidney Disease and Risk of Coronary Heart Disease in Korean Men

There have been many epidemiological researches of chronic kidney disease (CKD), accompanied by an increase in the incidence of coronary heart disease (CHD). However, as far as we know, little research has been done to examine the extent of the relationship between CKD and CHD as estimated by Framingham risk score (FRS) in Korean men. CKD was defined as either proteinuria or an eGFR of or = 20% (high). We defined FRS > or = 10% as more-than-a-moderate CHD risk group and FRS > or = 20% as a high CHD risk group, respectively. After adjusting for covariates, multivariable-adjusted logistic regression analyses showed a strong statistical significant relationship between CKD and high risk of CHD (adjusted OR, 1.95 [95% CI, 1.32-2.87]). Dipstick urinalysis and eGFR can be readily measured in most clinical settings. The measurement of kidney function may represent a relatively inexpensive and efficient way to identify individuals at higher risk for CHD.

Objective To study the effects and safety of levocarnitine and shuxuetong in treatment of the patients with chronic renal failure.Methods 94 patients with chronic renal failure were selected as research object,and they were randomly divided into group A(levocarnitine and shuxuetong group) 47 cases and group B(shuxuetong group) 47 cases.Group A were treated with levocarnitine oral solution and shuxuetong,and group B were treated with shuxuetong,then the percentage of effectiveness,incidence of adverse reactions of group A and group B and serum BUN,Scr,Hcy were analyzed.Results The percentage of effectiveness of group A was higher than that of group B,but the incidence of adverse reactions of the two groups had no difference,and the serum BUN,Scr,Hcy of group A and group B before the treatment had no differences(P＞0.05),those of group A and group B after treatment were compared there were significant differences(all P＜0.05).Conclusion The effects of levocarnitine oral solution and shuxuetong in treatment of patients with chronic renal failure were better.

Effects of chronic renal failure rabbit serum on proliferation and nuclear factor kappa B activation of rabbit arterial smooth muscle cells / 中华肾脏病杂志

Objective To investigate the effects of chronic renal failure rabbit serum on proliferation and nuclear factor kappa B (NF-κB) activation of rabbit arterial smooth muscle cells (ASMCs) and to explore the possible mechanism. Methods Rabbit model of chronic renal failure was established by the ligation of renal arterial branches. ASMCs were incubated in the media with various concentrations of chronic renal failure serum cultured in vitro. Cell proliferation was assessed by MTT. Cell apoptosis was detected by Hoechst33342 staining. NF-κB p65 nuclear translocation was analyzed by immunofluorescence. Expression of proliferating cell nuclear antigen (PCNA) and NF-κB p65 proteins in response to chronic renal failure serum in ASMCs was determined by Western blotting. Results Lower concentrations of chronic renal failure serum (≤ 10%) could significantly promot the proliferation of ASMCs in a dose- and time-dependent manner. Higher concentrations of chronic renal failure serum (＞10%) could significantly inhibit the proliferation and induce apoptosis of ASMCs compared to the normal control (P＜0.05). Under the stimulation of lower concentrations of chronic renal failure serum, the expression of PCNA and NF-κB p65 increased significantly compared to the normal control (P＜0.01), while decreased markedly under the stimulation of higher concentrations of chronic renal failure serum compared to the normal control (P＜0.01). Under the stimulation of 10% chronic renal failure serum, nuclear translocation of NF-κB p65 in ASMCs was found. Conclusions Different concentrations of chronic renal failure rabbit serum can effectively induce ASMCs proliferation or apoptosis. The mechanism of promoting proliferation may be mediated by activating NF-κB, which will be useful for the treatment of accelerated atherosclerosis in chronic renal failure.

Comparison of Effects of Radix Astragali and Triperygium Glucosides on Glomerular Mesangial Cells Proliferation and Interleukin-6 Secretion / 广州中医药大学学报

[Objective] To compare the effects of Radix Astragali (RA) and triperygium glucosides (TG) on glomerular mesangial cells (GMC) proliferation and interleukin-6 (IL-6) secretion. [Methods] GMC were cultured with in-vitro cell culture technology. Serum containing RA and serum containing TG were prepared with serum pharmacological methods. GMC proliferation was detected by methylthiazolyltetrazolium (MTT) assay and IL-6 level by enzyme-linked immunosorbent assay (ELISA) to evaluate the effect of low-, moderate- and high-dosages of RA-containing serum and TG-containing serum under the condition of GMC over-proliferation. [ Results] Different dosages of RA-containing serum and TG-containing serum inhibited GMC proliferation and IL-6 secretion in a dose-effect manner, and the inhibitory effect of high- and moderate-dosage TG and high-dosage RA was stronger. [Conclusion] Under the condition of in-vitro GMC over-proliferation, RA has the similar inhibitory effects on GMC proliferation and IL-6 secretion with TG. The combined treatment of RA and TG can reduce the dose of TG and probably has an action in increasing effect and reducing toxicity.
