Protective Effects of Mongolian Medicine Borantunggal on Rats with Chronic Renal Insufficiency

[Objectives]To observe the protective effects of Mongolian medicine Borantunggal on rats with chronic renal insufficiency.[Methods]Male Wister rats were gavaged with 50 mg/kg/d adenine for 12 consecutive weeks,and were intervened with positive control drug Niaoduqing and three groups of different doses of Mongolian medicine Borantunggal.The rats general state,such as body posture,hair color,activity status,renal function,thyroid gland,adrenal gland,and gonadal hormone levels,expression levels of inflammatory mediators,α-smooth muscle actin(α-SMA)and nuclear factor-κB(P65)in renal tissue,and histopathological changes of rat kidney were observed before and after treatment.[Results]The recovery of the general state of rats with chronic renal insufficiency in the low dose group after intervention with Mongolian medicine Borantunggal was the most obvious.Compared with the model group,the level of CRE in the low dose Mongolian medicine group decreased,and the difference was statistically significant(P<0.05).Compared with the normal group,the 24-h urinary protein in the low dose Mongolian medicine group had a declining trend,but the difference was not statistically significant(P>0.05).The urea level in low,medium and high dose Mongolian medicine groups showed a declining trend,and the effect of low dose Mongolian medicine was better.Compared with the model group,the feed intake of the low dose Mongolian medicine group had an increasing trend,while P and TCHO also had a declining trend.Compared with the model group,the levels of LH and COR in the low,medium and high dose Mongolian medicine groups decreased significantly,and the difference was statistically significant(P<0.05).The levels of T,T3 and T4 were significantly increased,the difference was statistically significant(P<0.05),and the effect of low dose Mongolian medicine was better.Compared with the model group,the levels of IL-6,TNF-αand HIF-1 in the low,medium and high dose Mongolian medicine groups were significantly reduced,and the difference was statistically significant(P<0.05).The levels of TGF-β1 and Ang II in the low dose Mongolian medicine group were significantly reduced,and the difference was statistically significant(P<0.05).The level of TGF-β1 in the medium and high dose Mongolian medicine groups decreased,and the difference was statistically significant(P<0.05).The expression of NF-κB P65 andα-SMA proteins in the low dose Mongolian medicine group showed a declining trend,which was better than Niaoduqing.[Conclusions]Mongolian medicine Borantunggal has significant protective and preventive effects on rats with adenine-induced chronic renal insufficiency.In particular,the dose of 0.31 kg/d had the most significant protective effect.Its action mechanism may be related to regulating hormone levels in the body,improving renal function,reducing renal inflammatory response,reducing the"three highs"in the kidney,and inhibiting renal tubular epithelial cell-to-mesenchymal transition and deposition of extracellular matrix(ECM).

Expression of HO-1 in Chronic Renal Insufficiency Rat Kidney and Implication

The expression, activity and clinical implication of heme oxygenase-1 (HO-1) in the chronic renal insufficiency (CRI) rat kidney and its mechanism were investigated The 5/6 nephrectomized rats were assigned to sham operation group, CRI group and Hemin group At the 8th week after second operation, blood pressure, urinary protein, serum creatinine(Scr) and BUN were measured Renal pathologic changes were observed The activity of HO and contents of erythropoietin (EPO) in serum and renal tissue were determined Immunohistochemistry was used to detect the expression and distribution of HO-1 in the CRI rat kidney As compared with CRI group, the urinary protein, blood pressure, Scr and BUN in Hemin group were reduced significantly ( P< 0 05) The glomerular mesangial proliferation, inflammatory cellular infiltration of renal interstitium and interstitial fibrosis were ameliorated significantly Immunohistochemistry and measurement of HO-1 activity revealed that the expression and activity of HO-1 was decreased in renal tissues and increased in serum in CRI group as compared with normal rats HO-1 distributed mainly in tubular epithelial cells The EPO contents in Hemin group were significantly higher than in CRI group Through up-regulating the EPO level in serum and renal tissues, HO-1 retards the progression of CRI

Low-molecular-weight dextran for optical coherence tomography may not be protective against kidney injury in patients with renal insufficiency

BACKGROUND Low-molecular-weight dextran(LMWD)is considered a safe alternative to contrast media for blood displacement during optical coherence tomography(OCT)imaging.AIM To investigate whether the use of LMWD for OCT is protective against kidney injury in patients with advanced renal insufficiency.METHODS In this retrospective cohort study,we identified 421 patients with advanced renal insufficiency(estimated glomerular filtration rate<45 mL/min/1.73 m2)who underwent coronary angiography or percutaneous coronary intervention;79 patients who used additional LMWD for OCT imaging(LMWD group)and 342 patients who used contrast medium exclusively(control group).We evaluated the differences between these two groups and performed a propensity score-matched subgroup comparison.RESULTS The median total volume of contrast medium was 133.0 mL in the control group vs 140.0 mL in the LMWD group.Although baseline renal function was not statistically different between these two groups,the LMWD group demonstrated a strong trend toward the progression of renal insufficiency as indicated by the greater change in serum creatinine level during the 1-year follow-up compared with the control group.Patients in the LMWD group experienced worsening renal function more frequently than patients in the control group.Propensity score matching adjusted for total contrast media volume consistently indicated a trend toward worsening renal function in the LMWD group at the 1-year follow-up.Delta serum creatinine at 1-year follow-up was significantly greater in the LMWD group than that in the control group[0.06(-0.06,0.29)vs-0.04(-0.23,0.08)mg/dL,P=0.001],despite using similar contrast volume.CONCLUSION OCT using LMWD may not be protective against worsening renal function in patients with advanced renal insufficiency.

Atherosclerosis in elderly patients with renal insufficiency

IntroductionAs people age,cardiovascular structure and function change and this is superimposed on by specific pathophysiologic disease mechanism.In addition to lipid levels,diabetes,sedentary lifestyle,and genetic factors that are known risks for coronary disease,hypertension,and stroke - the quintessential cardiovascular (CV) diseases related to atherosclerosis within our society - advancing age unequivocally confers the major risk.(Fig.1) Mortality due to cardiovascular disease is more than any other disease and creates enormous costs for the health care system.The main underlying problem in cardiovascular disease is atherosclerosis,a process that obstructs major arteries with lipid deposits and cell accumulation.1 Decreased kidney function (estimated GFR＜70 mL/min/1.73 m2) is an independent risk factor for cardiovascular disease and all-cause mortality in the general population.

Heparin-induced thrombocytopenia in renal insufficiency undergoing dialysis and percutaneous coronary intervention after acute myocardial infarction:A case report

BACKGROUND Heparin-induced thrombocytopenia(HIT)is a rare complication of heparin therapy,and is characterized by arteriovenous thrombosis and bleeding events.The incidence of HIT after percutaneous coronary intervention(PCI)in patients with myocardial infarction complicated with renal failure is rarely reported.CASE SUMMARY We report a 73-year-old man with acute myocardial infarction and renal failure who underwent hemodialysis and PCI,and developed a progressive decline in platelets and subcutaneous hemorrhage of both upper limbs after heparin treatment.In addition to a gradual decrease in platelets,the patient’s 4T's score was 7,and HIT antibody was positive,confirming the diagnosis of HIT.CONCLUSION Patients receiving heparin combined with antiplatelet therapy should be monitored closely,especially for their platelet count.In the case of thrombocytopenia,HIT should be highly suspected.When the diagnosis of HIT is confirmed,timely individualized treatment should be delivered.

Long term clinical outcomes in patients with moderate renal insufficiency undergoing stent based percutaneous coronary intervention

Background Patients with end-stage renal disease have a high mortality from coronary artery disease, but the impact of moderate renal insufficiency on clinical outcomes after percutaneous coronary intervention （PCI） and the effect of drug-eluting stent implantation in these patients remain unclear. This study determined the long-term effect of moderate renal insufficiency on death and major adverse cardiac events （MACE） after stent based PCI and examined whether drug-eluting stent implantation could favourably influence clinical outcome. Methods Major adverse cardiac events and causes of mortality were determined for 1012 patients undergoing percutaneous intervention from January 1, 2002 to December 31, 2004 at Shanghai Ruijin Hospital. Based on estimated creatinine clearance levels, long term outcomes were compared between patients with estimated creatinine clearance 〈60 ml/min （renal insufficiency group; n=410） and those with estimated creatinine clearance ≥60 ml/min （control group; n=602）. Subgroup analysis was also made for patients with renal insufficiency between drug eluting stent （n=264） and bare metal stent implantation （n=146） during PCI. Results During follow-up （average 17 months） after successful PCI, all causes of death （7.1% vs 2.3%, P〈0.01） and cardiac death （3.4% vs 1.0%, all P〈0.01） were significantly higher in renal insufficiency group than in control group. For patients with moderate renal insufficiency, drug-eluting stent implantation reduced significantly all causes of death （5.3% vs 10.9%, P〈0.05） and occurrence of major cardiac adverse events （15.1% vs 24.6%, P〈0.05） compared with bare metal stents. Conclusions Moderate renal insufficiency is an important clinical factor influencing the mortality after PCI in patients with coronary artery disease and the use of drug-eluting stents should be the preferred therapy for the improvement of long-term outcomes in such patients.

A Multicentre Prospective Evaluation of the Impact of Renal Insufficiency on In-hospital and Long-term Mortality of Patients with Acute ST-elevation Myocardial Infarction

Background：Numerous previous studies have shown that renal insufficiency （RI） in patients with acute coronary syndrome is associated with poor cardiovascular outcomes.These studies do not well address the impact of RI on the long-term outcome of patients with acute ST-elevation myocardial infarction （STEMI） in China.The aim of this study was to investigate the association of admission RI and inhospital and long-term mortality of patients with acute STEMI.Methods：This was a multicenter,observational,prospective-cohort study.718 consecutive patients were admitted to 19 hospitals in Beijing within 24 hours of onset of STEMI,between January 1,2006 and December 31,2006.Estimation of glomerular filtration rate （eGFR） was calculated using the modified abbreviated modification of diet in renal disease equation-based on the Chinese chronic kidney disease patients.The patients were categorized according to eGFR,as normal renal dysfunction （eGFR ≥ 90 ml·min^-1·1.73 m^-2）,mild RI （60 ml·min^-1· 1.73 m^-2 〈 eGFR 〈 90 ml·min^-1· 1.73 m^2） and moderate or severe RI （eGFR 〈 60 ml·min^-1· 1.73 m^2）.The association between RI and inhospital and 6-year mortality of was evaluated.Results：Seven hundred and eighteen patients with STEMI were evaluated.There were 551 men and 167 women with a mean age of 61.0 ＆#177; 13.0 years.Two hundred and eighty patients （39.0%） had RI,in which 61 patients （8.5%） reached the level of moderate or severe RI.Patients with RI were more often female,elderly,hypertensive,and more patients had heart failure and stroke with higher killip class.Patients with RI were less likely to present with chest pain.The inhospital mortality （1.4% vs.5.9% vs.22.9%,P 〈 0.001）,6-year all-cause mortality （9.5% vs.19.8 vs.45.2%,P 〈 0.001） and 6-year cardiac mortality （2.9% vs.12.2% vs.23.8%,P 〈 0.001） were markedly increased in patients with RI.After adjusting for other confounding factors,classification of admission renal function was an independent predictor of inhospital mortality （Odd ratio,1.966; 95% confidence interval [CO,1.002-3.070,P =0.019）,6-year all-cause mortality （relative risk [RR] =1.501,95% CI：1.018-4.373,P =0.039） and 6-year cardiac mortality （RR =1.663,95% CI：1.122-4.617,P =0.042）.Conclusions：RI is very common in STEMI patients.RI evaluated by eGFR is an important independent predictor of short-term and long-term outcome in patients with acute STEMI.

Coronary stenting does not improve the long-term cardiovascular outcome of patients with mild to moderate renal insufficiency

Background Several studies have shown that coronary stenting reduces the frequency of clinical and angiographic restenosis in patients with mild to moderate renal insufficiency. However, less is known about the long-term benefits of stent use in this population. This study was aimed to determine the impact of coronary stenting on extended （5 years） long-term outcomes of patients with chronic renal insufficiency. Methods The study included 602 consecutive patients who underwent successful percutaneous coronary intervention with stenting. Renal insufficiency was defined as an estimated glomerular filtration rate 〈60 rrd.min-1-｜.73 m-2. The major adverse cardiac events were compared for patients with （n=160） and without （n=442） renal insufficiency. Results After the third year of follow-up, nonfatal myocardial infarction and revascularization rates were significantly increased in patients with renal insufficiency compared with those without renal dysfunction （16.9% vs 7.7%, P=0.001; 29.4% vs 15.8%, P 〈0.001）. In patients who had recurrent cardiovascular events, a significantly higher rate of de novo stenosis revascularization was found in patients with renal insufficiency than without renal insufficiency （57.7% vs 22.7%, P 〈0.001）, while there was no significant difference in target lesion revascularization between the groups （51.9% vs 43.6%, P=0.323）. Multivariate analysis demonstrated an independent impact of the presence of renal insufficiency on the major adverse cardiac events （hazard ratio： 1.488, 95% confidence interval： 1.051-2.106, P=0.025） and de novo stenosis （hazard ratio： 5.505, 95% confidence interval： 2.151-14.090, P 〈0.001）. Conclusions The late major adverse cardiac events, after successful coronary stenting, is increased in patients with an estimated glomerular filtration rate 〈60 ml.min-1.1.73m-2. This might be associated with increased risk of de novo stenosis in this population. Chin Med J 2009; 122（2）： 158-164

Effect of bivalirudin on coagulation function and prognosis in patients with coronary artery disease and renal insufficiency undergoing PCI

Background Renal insufficiency is associated with an excess risk of vascular complications and bleeding events in patients who undergo PCI. Heparin is still used commonly for PCI, but the bleeding complications is high. However, Bivalirudin is similar to heparin in ischemic complications and superior to the bleeding complica- tions. Methods A total of 181 patients with coronary artery disease and renal insufficiency were randomly as- signed two treatment groups： Bivalirudin （n = 90）, unfractionated heparin （n = 91）. Activated clotting time （ACT） was determined in patients at 5 min after undergoing PCI at the end of operation immediately （stopping drug im- mediately） , and 30 min,1 h, 2 h after stopping drug. Activated partial thromboplastin time （APTT）, thrombin time （TT）, proth rombin time （PT）, fibrinogen （FIB） index were measured before treatment, 6 h, 24 h and 72 h af- ter the treatment through an automated coagulation analyzer. Platelet count was monitored before treatment and 24 h after treatment. The end points were the proportion of net adverse clinical events （NACE） and stent throm- bosis at 30 days. Results The use of bivalirudin was associated with a statistically significant higher at 5 min af- ter treatment, end of operation immediately （P 〈 0.05）, with statistically significant lower at lh after stopping drug , 2h after stopping drug （P 〈 0.05）. There were no differences between patients at blood coagulation and platelet after operation （P 〉 0.05）, no differences in the 30-day rates of stent thrombosis （0% vs. 0%, P = 1）. Elev- en patients（12.22%） treated with bivalirudin vs. 24 （26.38%） treated with heparin experienced an adverse clinical events at 30 days （relative risk[RR], 0.46; 95%CI, 0.36-0.56; P 〈 0.025）. There were no differences in the major adverse cardiac or cerebral event at the 30-day end point（1.11% vs. 2.20%, P 〉 0.05）. The bleeding at 30 days was abated by using bivalirudin compared with unfracfionated heparin （11.11% vs. 24.18%, P 〈 0.05）. Conclu- sions Compared with the unfractionated heparin, bivalirudin is more quickly in taking effect and recovering and more efficient for PCI in patients with coronary artery disease and renal insufficiency.

Retroperitoneal laparoscopic partial resection of the renal pelvis for urothelial carcinoma:A case report

BACKGROUND The standard treatment of transitional cell carcinoma of the upper urinary tract consists of radical nephroureterectomy with bladder cuff removal,which can be performed either in open or laparoscopy or robot-assisted laparoscopy.Treatment of chronic renal insufficiency patients with upper urothelial tumor is in a dilemma.Urologists weigh and consider the balance between tumor control and effective renal function preservation.European Association of Urology guidelines recommend that select patients may benefit from endoscopic treatment,but laparoscopic treatment is rarely reported.CASE SUMMARY In this case report,we describe a case of 79-year-old female diagnosed with urothelial carcinoma of the renal pelvis and adrenal adenoma with chronic renal insufficiency.The patient was treated with retroperitoneal laparoscopic partial resection of the renal pelvis and adrenal adenoma resection simultaneously.CONCLUSION Retroperitoneal laparoscopic partial resection of the renal pelvis is an effective surgical procedure for the treatment of urothelial carcinoma of the renal pelvis.

Evidence based review of management of cardiorenal syndrome type 1

Cardiorenal syndrome(CRS)type 1 is the development of acute kidney injury in patients with acute decompensated heart failure.CRS often results in prolonged hospitalization,a higher rate of rehospitalization,high morbidity,and high mortality.The pathophysiology of CRS is complex and involves hemodynamic changes,neurohormonal activation,hypothalamic-pituitary stress reaction,inflammation,and infection.However,there is limited evidence or guideline in managing CRS type 1,and the established therapeutic strategies mainly target the symptomatic relief of heart failure.This review will discuss the strategies in the management of CRS type 1.Six clinical studies have been included in this review that include different treatment strategies such as nesiritide,dopamine,levosimendan,tolvaptan,dobutamine,and ultrafiltration.Treatment strategies for CRS type 1 are derived based on the current literature.Early recognition and treatment of CRS can improve the outcomes of the patients significantly.

The Usefulness of Renal Doppler Parameters in Chronic Kidney Disease: Is There a Cut-Off Value to Estimate End Stage Kidney Disease?

Aims: In this study, Doppler parameters were studied in patients with advanced stage renal disease, and the relationship between Doppler parameters and renal disease stage was investigated. Doppler values were evaluated for a cut-off value between normal and end-stage kidney disease group. Materials and methods: 50 patients with chronic kidney disease and 15 patients belonging to the same age group and with normal serum creatinine levels were comprised of the study and control groups. Resistivity and pulsatality indices were measured at the main renal arteries and interlobular arteries at both sides. Results: Statistically significant differences were found between the PI and RI values obtained from the main renal and interlobular arteries. PI sums were compared with those from the control group, and a cut-off value of 2.15 was found, with a sensitivity of 90% and a specificity of 86.7%. Conclusion: Any increase in the RI and PI values obtained from the main renal and interlobular arteries must bring to mind the possibility of advancing renal damage and interstitial fibrosis. Patients with and without renal parenchymal damage can be differentiated by means of comparing the total PI values obtained from the right and left main renal and interlobular arteries.

The relationship between serum levels of uric acid and prognosis of infection in critically ill patients

BACKGROUND:Serum uric acid level is associated with some chronic diseases and prognosis of severe infection.This study aimed to investigate the relationship between serum uric acid(SUA)and prognosis of infection in critically ill patients.METHODS:The data from 471 patients with infection admitted from January 2003 to April 2010 were analyzed retrospectively at Huashan Hospital Affiliated to Fudan University,Shanghai,China.The data of SUA,serum creatinine,blood urea nitrogen(BUN) and other relevant examinations within24 hours after admission were recorded and the levels of SUA in those patients were described,then Student's t test was used to evaluate the relationship between SUA and pre-existing disorders.Different levels of SUA were graded for further analysis.The Chi-square test was used to examine the difference in the prognosis of infection.RESULTS:The mean initial level of SUA within 24 hours after admission was 0.232±0.131mmol/L and the median was 0.199 mmol/L.Remarkable variations in the initial levels of SUA were observed in patients with pre-existing hypertension(t=-3.084,P=0.002),diabetes mellitus(t=-2.487,P=0.013),cerebral infarction(t=-3.061,P=0.002),renal insufficiency(t=-4.547,P<0.001),central nervous system infection(f=5.096,P<0.001) and trauma(r=2.875,P=0.004).SUA was linearly correlated with serum creatinine and BUN(F=159.470 and 165.059,respectively,P<0.001).No statistical correlation was found between the initial levels of SUA and prognosis of infection(x^2=60.892,P=0.100).CONCLUSION:The current study found no direct correlation between the initial levels of SUA after admission and prognosis of infection in critically ill patients.

Systemic lupus erythematosus and antineutrophil cytoplasmic antibody-associated vasculitis overlap syndrome in a 77-year-old man: A case report

BACKGROUND Systemic lupus erythematosus(SLE)and antineutrophil cytoplasmic antibodyassociated vasculitis(AAV)are classically thought to cause renal impairment and small vessel vasculitis with different pathophysiologies.Their overlap constitutes a rare rheumatologic disease.To date,only dozens of such cases with biopsyproven glomerulonephritis have been reported worldwide typically in women of childbearing age.Here,we present a unique clinical case due to its rarity and individualized treatment of a Chinese man in his eighth decade of life.CASE SUMMARY A 77-year-old man was admitted to several hospitals for shortness of breath and received nonspecific treatments over the past 3 years.As his symptoms were not completely relieved,he visited our hospital for further treatment.Laboratory examinations revealed kidney dysfunction,severe anaemia,hypocomplementemia,glomerular proteinuria,and microscopic haematuria.Antinuclear antibodies,as well as anti-dsDNA antibodies,were positive.Computed tomography of the chest showed right pleural effusion.Renal biopsy was performed,and histology suggested crescentic glomerulonephritis,pauci-immune type.After treatment with plasmapheresis,glucocorticoid,and cyclophosphamide,the disease was in remission,and the patient remained in a stable condition for over 3 years post-hospital discharge.CONCLUSION Due to its complexity and rarity,SLE and AAV overlap syndrome is easily misdiagnosed.An accurate diagnosis and treatment at the earliest stage may significantly improve the condition and reduce irreversible organ injury.

Subclinical proximal tubulopathy in hepatitis B:The roles of nucleot(s)ide analogue treatment and the hepatitis B virus

BACKGROUND The recommended monitoring tools for evaluating nucleot(s)ide analogue renal toxicity,such as estimated glomerular filtration rate(eGFR)and phosphatemia,are late markers of proximal tubulopathy.Multiple early markers are available,but no consensus exists on their use.AIM To determine the 24 mo prevalence of subclinical proximal tubulopathy(SPT),as defined with early biomarkers,in treated vs untreated hepatitis B virus(HBV)-monoinfected patients.METHODS A prospective,non-randomized,multicenter study of HBV-monoinfected patients with a low number of renal comorbidities was conducted.The patients were separated into three groups:Naïve,starting entecavir(ETV)treatment,or starting tenofovir disoproxil(TDF)treatment.Data on the early markers of SPT,the eGFR and phosphatemia,were collected quarterly.SPT was defined as a maximal tubular reabsorption of phosphate/eGFR below 0.8 mmoL/L and/or uric acid fractional excretion above 10%.The prevalence and cumulative incidence of SPT at month 24(M24)were calculated.Quantitative data were analyzed using analyses of variance or Kruskal-Wallis tests,whereas chi-squared or Fisher’s exact tests were used to analyze qualitative data.Multivariate analyses were used to adjust for any potential confounding factors.RESULTS Of the 196 patients analyzed,138(84 naïve,28 starting ETV,and 26 starting TDF)had no SPT at inclusion.At M24,the prevalence of SPT was not statistically different between naïve and either treated group(21.1%vs 30.7%,P<0.42 and 50.0%vs 30.7%,P=0.32 for ETV and TDF,respectively);no patient had an eGFR lower than 50 mL/min/1.73 m²or phosphatemia less than 0.48 mmoL/L.In the multivariate analysis,no explanatory variables were identified after adjustment.The cumulative incidence of SPT over 24 mo(25.5%,13.3%,and 52.9%in the naïve,ETV,and TDF groups,respectively)tended to be higher in the TDF group vs the naïve group(hazard ratio:2.283,P=0.05).SPT-free survival at M24 was 57.6%,68.8%,and 23.5%for the naïve,ETV,and TDF groups,respectively.The median survival time without SPT,evaluated only in the TDF group,was 5.9 mo.CONCLUSION The prevalence and incidence of SPT was higher in TDF-treated patients compared to naïve patients.SPT in the naïve population suggests that HBV can induce renal tubular toxicity.

Long-term results of liver transplantation for over 60 years old patients with hepatitis B virus-related end-stage liver disease

BACKGROUND： Hepatitis B virus（HBV）-related end-stage liver disease is the leading indication for liver transplantation in China, but long-term results of liver transplantation in patients aged over 60 years are not clear. The present study was to reveal the natural history of liver recipients with hepatitis B older than60 years.METHODS： The recipients who had received liver transplantation between December 2003 and December 2005 were divided into two groups： those equal or older than 60 years（older group,n60） and those younger than 60 years（younger group, n305）.Risk factors for poor long-term outcome in patients aged over 60 years were also analyzed.RESULTS： Except for age and preexisting chronic disease（P0.05）,no significant differences were observed in perioperative characteristics between the two groups. There was also no significant difference in HBV and hepatocellular carcinoma recurrence（P0.05）. The actuarial 1-, 3-, 5- and 8-year survival rates were 81.6%, 71.6%, 66.7% and 63.3% respectively for the older group vs 84.9%, 77.7%, 70.8% and 65.6% for the younger group（P0.05）. Multivariate analyses showed that pre-liver transplant renal insufficiency was a risk factor for poor outcome in the older group（odds ratio=3.615, P0.014）.CONCLUSIONS： Liver transplantation is safe and feasible for patients with HBV-related end-stage liver disease aged over 60years. Older patients with renal insufficiency should undergo transplantation earlier than younger patients.

Noninvasive identificational diagnosis of diabetic nephropathy and non-diabetic renal disease based on clinical characteristics of Traditional Chinese Medicine symptom pattern and conventional medicine

OBJECTIVE:To study the clinical characteristics relating to differential diagnosis of diabetic nephropathy(DN) and non-diabetic renal disease(NDRD).METHODS:The subjects were patients with type 2 diabetes mellitus(T2DM) complicated with chronic kidney disease(CKD).Western medical history data and Traditional Chinese Medicine(TCM) symptom pattern were collected,and logistic regression was used to analyze.RESULTS:Blood deficiency pattern [odds ratio(OR) = 2.269,P = 0.017] and Qi stagnation pattern(OR = 1.999,P = 0.041) are independently related to DN.CONCLUSIONS:TCM factors blood deficiency pattern and Qi stagnation pattern are relating to differential diagnosis of DN and NDRD.

Is the Distribution of Microorganisms and Peritonitis Affected by Seasonality in Peritoneal Dialysis?

Introduction: Peritonitis continues to be the main complication for patients on peritoneal dialysis (PD). Objective: To determine the frequency of peritonitis according to the disease-causing microorganism and its distribution throughout the year, linking to seasonality. Methods: A retrospective study conducted in the Dialysis Unit of the Hospital S&atildeo Lucas, PUCRS (HSL-PUCRS). Patients undergoing PD between January 1984 and September 2013 were included. Descriptive statistics were used and Fisher’s exact test with Monte Carlo simulation for comparison between the categorical variables. Results: Of 415 evaluated patients, 66% had at least one episode of peritonitis with an incidence rate of 0.68 episode/year. There were 601 peritonitis episodes in total. The most common microorganism was coagulase-negative Staphylococcus (26.6%, n = 160), followed by Staphylococcus aureus (16.3%, n = 98), with 16.3% of the sample being negative culture. Most episodes occurred in the months of January (10.3%, n = 62) and May (10.1%, n = 61), while June had the lowest occurrence (5.2%, n = 31). The number of episodes observed in January and May were significantly higher when compared to June

Effects of Oenethera Oil on Plasma Lipid，Thromboxane A2 and Angiotensin Ⅱ of Chronic Renal Insufficiency

Oenethera biennis oil was administered (6 g per day) in 23 chronic renal insufficiency pa-tients over a 4 week period. Changes of serum creatinine, creatinine clearance, plasma lipid, renin activity,and angiatensin , urinary thromboxane B2 and 6-keto-prostaglandin F1 were observed before and after thetreatment. Results showed that after treatment. the creatinine clearance increased, serum total cholesterol,triglyceride and low density lipoprotein decreased, high density lipoprotein increased, plasma renin activity,angiotensin and urinary thromboxane B2 decreased significantly. The conclusion was that Oenethera bien-nis oil could improve the pathological process of renal diseases, and has benoficial effects on plasma lipiddisorder and glomerular hemodynamics .
