Objective To summarize continuous veno- venous hemofiltration (CVVH) treatment of infants with complex congenital heart disease in children with acute renal failure after treatment. Methods A retrospective analysis was carried out in six cases of infants with congenital heart disease with application of CVVH. The children were given monitoring and anticoagulant treatment. The renal function, electrolytes and urine volume were compared before and after the treatment. Results The amount of urine increased, blood circulation and electrolytes remained stable in six patients 17.5-135.0 hours after CVVH. Conclusions The CVVH therapy can be applied to treat infants with congenital heart disease complicated with acute renal failure, but CVVH treatment should focus on anticoagulants and blood volume since complicated state of illness, low age, low body weight of children patients.

BACKGROUND:To explore the methods for secondary limb revascularization after endovascular repair is one of the most urgent research topics.
OBJECTIVE:To investigate the biological mechanism about the transplantation of autologous peripheral blood stem cel s to lead and perfect the effect of ischemic tissue for secondary revascularization.
METHODS:Forty-two patients with critical low limb ischemia were selected and treated with endovascular repair as first revascularization and transplantation of autologous peripheral blood stem cel s as secondary revascularization. The secondary revascularization was carried out at 3 months after the first blood flow remodeling. The patients receiving secondary revascularization were fol owed for 4 years.
RESULTS AND CONCLUSION:After transplantation of autologous peripheral blood stem cel s, the patients complained that the rest pain of the lower leg was relieved obviously and intermittent claudication distance was significantly lengthened. Limb salvage rate was 100%. Skin temperature index was 1.6±0.3, transcutaneous oxygen pressure was (5.00±1.26) kPa, ankle-brachium index was 0.9±0.2, photoplethysmograpy index was 0.8±0.1, saturation of blood oxygen was (79.4±20.4)%, and digital subtraction angiography score was (1.3±0.2)

Objective: To investigate the pharmacokinetic and pharmacodynamic changes of Yangyin Tongnao Granules (YTG) in cerebral ischemia reperfusion rats after the compatibility of main effective parts (total alkaloids, total flavonoids, total saponins and total phenolic acids). Methods: By using the orthogonal design to research the main effective parts of YTG, nine different dosage ratios combinations were formed, which were used for oral administration in cerebral ischemia reperfusion rats. High performance liquid chromatography-diode array detector (HPLC-DAD) was used to determine the concentration of puerarin, ferulic acid, and ligustrazine in rat plasma at different time points. The non-compartmental model was used to fit the pharmacokinetic parameters by Drug and Statistics (DAS) 3.2.6 software. The total quantum statistical moment analysis method and comprehensive evaluation method were used to evaluate the total pharmacokinetic characteristics. Meanwhile, the content of superoxide dismutase (SOD) and catalase (CAT) were determined by enzyme-linked immunosorbent assay (ELISA) kits. Finally, the PK-PD model and the quantitative equations between drug concentration and efficacy were obtained. Results: The pharmacokinetic characteristics of puerarin, ferulic acid and ligustrazine in cerebral ischemia-reperfusion rats were different. Total statistical moment and comprehensive score study showed that different combinations had different effects on ACUT, mean retention time (MRT), and comprehensive evaluation. The effective parts inhibited the reduction of oxidation indexes such as SOD and CAT. Sigmoid-Emax models were adopted in all PK-PD models, and the fitting results had a good correlation with the measured data. The R values were more than 0.85. Conclusion: Compatibility of YTG activity parts had a certain effect on their pharmacokinetic behaviors and antioxidation in model rats. The total quantum statistical moment analysis and comprehensive evaluation method can be used to study the pharmacokinetics of multi-component traditional Chinese medicine prescriptions. PK-PD model could be used to predict and evaluate the correlation between pharmacokinetics and pharmacodynamics of traditional Chinese medicine prescriptions.

Objective The aim of this study was to evaluate of adilty of two acute renal failure-specific scoring systenms (the classification by Bellome et al and the AKIN criteria) for predicting hospital mortality after cardiac surgery in adult patients. Methods Between October 1 st 2006 to Decemjber 31 st 2006, 509 adult patients who ungerwent coronary artery bypass grafting (CABG) and/ or valve operation were enrolled in this study. The medical data collection included gender, age, types of operation, perioperative he- modynamic parameters, urine output, biochemical parameters and outcome. Renal function was assessed daily according to the classi- ficatinn by Bellomo and the AKIN criteria, respectively. As references, Acure Physiology and Chronic Health Evaluation(APACHE) Ⅱ and Sepsis-related Organ Failure Assessment (SOFA) score were also calculated. Resuits Three hundred and forty-one patients were male (67.0%), and 168 were female (33.0%), mean age was (56.2±12.0) years old. Tnree hundred and nine patieats un- derwent CABG, 182 underwent valve operation and 18 underwent CABG plus valve operation, Mean duration of ventilation support was (20.4±17.7) houra, and the ICU stay was (1.4±1.0) days. Postoperative hospital stay was (13.8±9.1) days. According to the classification by Bellomo., the highest in-hospital mortality was 52.9% in ARFS group. Mahiplicatinn of in-hospital morality rate was abserved (X2 for trend, P<0.01) in 0.4% (non-ARF), 1.2% (stage 1), 12.0% (stal～ 2) and 32.4% (stage 3) of pa- tients based on the AKIN criteria. By applying the area under the receiver operating characteristic ourve, the classification by Bellomo and the AKIN criteria had good discriminative power. Furthering, multivariate logistic regression analysis verified that the Odds Ratio of the AKIN criteria was 5.478 (P =0.028, 95% Confidence Interval 1.027- 24.856), after adjusting for gender and age. Con- clusion Analytical data confinned good discriminative power of both the AKIN criteria and the classification by Bellomo for predicting hospital mortality of adult postoperative patient with ARF.
