Objective To evaluate the different methods of blood purification for acute septic renal injury (AKI) in respect of outcome by using RIFLE(risk,injury,failure,loss and end-stage renal disease)criteria and A-PACHE Ⅱ score. MethodData of 96 patients with ASRI admired to ICU of Tianhe Hospital, Tianjin, from March 2004 to September 2006 were analyzed. Including criteria: 2001 International Sepsis Definitions Conference and 2004 RIFLE criteria of AKI. The methods of blood purification used continuous renal replacement therapy (CRRT, n=54) and imermittent hemodialysis (IHD, n=42).The patients of CRRT group could be classified into stages Ⅰ, Ⅱ and Ⅲ referred to RIFLE criteria. Excel was evaluated to set up clinical data base from documented material. Data were analyzed with SPSS version 11. 5 software. Physical signs, laboratory findings, variation of APACHE Ⅱ score and outcomes of patients were documented evaluated. Data of two groups compared using indepent samples T test, before and after the treatment compared using paired-samples T test, rate compared using chi-square test. Results①There were no statistical differences in APACHE Ⅱ score and creatinine (Cr) between CRRT group and IHD group before treatment (P>0.05). The mortalities of CRRT group and IHD group were 51.9% and 52.4%, respectively (P>0.05), but the recovery rates of renal function in CRRT group and IHD group were 92.3% and 65.0% ,respectively (P< 0.05).②Mean arterial pressure (MAP),oxygen saturation (SpO2) of CRRT group were lower than those of IHD group (P<0.05) and they increased to some extent after treatment (P< 0.05). ③In the patients of stag Ⅰ ,the survival rate was 78.6%, APACHE Ⅱ score was 25.4± 2.5 before treatment, renal function recovery rate was 90.9% ,and APACHE Ⅱ changed - 13.6 ± 4.3, while those relevant markers in the patients of stage Ⅲ were 38.1%, 36.1 ± 5.7,62.5 % and - 7.1 ± 4.2, respectively (P<0.05). ConclusionsThe RIFLE criteria has guiding significance for the early diagnosis and prognosis of ASRI,and the RIFLE and APACHE Ⅲ score may help to choose the optimum opportunity of treatment and the early CRRT as soon as possible after diagnosis can improve the outcome of patients with acute septic renal injury.

Objective To compare the image quality and patient radiation dose of coronary computed tomography angiography (CCTA) received by prospectively-gated step-and-shoot (SAS) technique with those obtained by retrospectively-gated spiral (RGS) technique on a 256-slice CT scanner. Methods A total of 200 patients were enrolled in this study. One hundred patients underwent CCTA with SAS mode were subdivided into two groups: ( 1 ) 50 patients with an average heart rate (HR) ≤70 bpm were scanned with a data acquisition time window centered at the 75% of the R-R cycle ( group A) and (2) 50 patients with HR > 70 bpm were scanned with the data acquisition time window centered at the 45% of the R-R cycle, including a phase tolerance of ±% (group B). Other 100 patients underwent CCTA with RGS mode and ECG-based tube current modulation were also subdivided into two groups: (3) 50 patients with HR ≤70 bpm were scanned with cardiac dose right set to phase of 75% (group C) and (4) 50 patients with HR > 70 bpm were scanned with cardiac ose Rdight set to phases of 45% and 75% (group D). All patients were grouped in randomized order. The image quality of CCTA were evaluated using a rank scale from 1 to 4 ( 1 : excellent ; 4 : non-assessable ) .Radiation dose of the four groups received was also estimated. The image quality between groups was compared by Mann-Whitney U test.The radiation dose between groups was compared by t test. For the 100 patients received by prospective ECG-gated CCTA, the receiver operating characteristic curve (ROC) was used to analyze the CCTA image quality and average heart rate to determine the uppercutoff of HR for obtaining diagnostic coronary images with SAS mode. A spearman correlation analysis was also performed to analyze the correlation of HR and image quality in patients underwent CCTA with SAS mode.Results Of 2338 coronary artery segments, excellent or good image quality( score of 1 or 2) was achieved in 96. 5% (585 of 606) in group A, 77.7% (445 of 573 ) in B,96. 1% (548 of 570) in C, and 85. 7% (505/589) in D, with no significant difference for A vs C(Z =- 1. 351 ,P >0. 05) and with significant differenceS for B vs D (Z= -2. 236,P <0. 05). Linear correlation analysis indicated a significant degradation of image quality with the increase of heart rate using SAS mode (Spearman correlation, r = 0. 577, P <0. 01 ). ROC analysis established an upper HR threshold of 78 bpm for obtaining diagnostic image quality using SAS mode( AUC = 0. 827, P < 0. 05 ). The average radiation dose in group A [ ( 2. 6 ± 0. 5 ) mSv]reduced 75 % comparing with that in group C [ ( 10. 6 ± 2. 3 ) mSy], and the average radiation dose in group B [ ( 4.0 ± 0. 7 ) mSy]reduced 69% comparing with that in group D [ ( 13.0 ± 1. 4) mSv]. ConclusionUsing SAS mode to perform low-dose CCTA with 256-slice helical CT could keep the image quality and reduce radiation dose significantly. Our preliminary experience suggests a good promise of this technique which could be applied to a wider group of patients such as with higher heart rates.

The heart and kidney damage is a clinical disease commonly seen, the 2 organs can interact with each other as cause and effect, leading to a series of clinical symptoms which is the cardiorenal syndrome (CRS). In 2008, according to the connection between the heart and kidney, the nephrologists Ronco, etc, completed the definition and classification of CRS, including type Ⅰ and type Ⅲ of CRS being acute cardiorenal syndrome (ACRS). ACRS refers to the fact that when the damage of heart or kidney dysfunction influences each other leading to a clinical syndrome caused by a sharp deterioration of cardiorenal function. At present, no definite diagnostic criteria for ACRS have yet been made. The pathogenesis of ACRS may be related to the renin-angiotensin-aldosterone system (RAAS), nitric oxide-reactive oxygen species (NO-ROS) system, inflammatory reaction, the excessive activation of sympathetic nervous system and so on. Clinically, about 50% of ACRS patients are accompanied by acute decompensated cardiorenal dysfunction or failure, that seriously impact on the patients' clinical prognosis and survival rate, so it is necessary to find an effective therapeutic regimen. At present, the treatments of ACRS have mainly the diuretic, angiotensin converting enzyme inhibitor (ACEI), angiotensin receptor inhibitor (ARB), β-receptor blocker, positive inotropic drugs, recombinant human erythropoietin, recombinant human brain natriuretic peptide, continuous blood purification (CBP) etc, and traditional Chinese medicine (TCM) also has a certain effect for improving the clinical symptoms of ACRS patients. Now the pathogenesis, diagnosis, and combined treatment of TCM and western medicine for treatment of ACRS are summarized.
