Objective To investigate the value of clinical parameters in predicting the initiation of renal replacement therapy(RRT) in acute kidney injury (AKI) patients with cardiorenal syndrome (CRS).Methods A total of 75 AKI patients hospitalized with CRS were enrolled.All patients received pharmacologic therapy on the beginning 3 days.The patients whose heart function improved were divided into control group (n=39),and the patients whose heart function worsened were divided into RRT group (n=36).Clinical and laboratory data on the first day and the fourth day were collected and analyzed.The factors on the first day were labeled asⅠ ,and those on the fourth day were labeled asⅡ. The ratio of some parameters calculated were labeled asⅡ/Ⅰ .Area under curve (AUC) of receiver operating characteristic curve (ROC) of these factors was used to evaluate the sensitivity and specificity in predicting the initiation of RRT.Results The patients in RRT group had significantly higher levels of BNP-Ⅱ,BNP Ⅱ / Ⅰ and creatinine Ⅱ / Ⅰ (P ＜ 0.01),and lower levels of 24 hours urine volume-Ⅰ and 24 hours urine volume-Ⅱ (P ＜ 0.01).From ROC curve analysis,the AUC of 24 hours urine volume-Ⅰ,24 hours urine volume-Ⅱ,creatinine Ⅱ / Ⅰ,BNP-Ⅱ levels and BNP Ⅱ/Ⅰ to predict RRT were 0.736,0.875,0.747,0.779 and 0.894 respectively.When the cutoff values of 24 hours urine volume-Ⅰ,24 hours urine volume-Ⅱ,BNP-Ⅱ levels,BNP Ⅱ / Ⅰ and creatinine Ⅱ / Ⅰ were 905 ml (sensitivity 75％,specificity 94.9％),1450 ml (sensitivity 75％,specificity 100％),3360 ng/L (sensitivity 72.2％,specificity 100％),1.37 (sensitivity 75％,specificity 100％) and 1.25 (sensitivity 72.2％,specificity 94.4％) respectively,the value of the parameters to predict RRT was high.Conclusions The 24 hours urine volume,BNP levels after treatment and the dynamic changes of BNP levels and creatinine levels can be used as predictors of the initiation of RRT in the AKI patients with CRS.

Objective To compare the cardiac structure and function between diabetic and non-diabetic with different peritoneal transport type.Methods A total of 84 patients with continuous ambulatory peritoneal dialysis (CAPD) in our center for 6 months were enrolled in this study.Forty-six patients of subjects were diabetic,another 38 were non-diabetic.Patients were divided into four groups according to the results of peritoneal equilibration test (PET) and the ratio of creatinine concentration in dialysate solution and plasma (D/P creatinine concentration).Patients with D/P creatinine concentration ＞ 0.65 were with high permeability and otherwise were low permeability.The four groups were diabetic-H (high permeability) group,diabetic-L(low permeability) group,non-diabetic-H (high permeability) group,non-diabetic-L (low permeability) group.The levels of left atrial diameter (LAD),left ventricular diameter(LVD),interventricular septal thickness(IVST),left ventricular posterior wall thickness(LVPWT),left ventricular ejection fraction(LVEF) were measured before and after 6-month peritoneal dialysis by ultrasonic doppler.Results Before peritoneal dialysis,there were no significant difference in the terms of all parameters among four groups(P ＞0.05).After 6 months of peritoneal dialysis,the albumin levels,IVST,LVPWT and LVEF in diabetic-L group,non-diabetic-L,diabetic-H group and non-diabetic-H group were ((36.57 ± 3.34),(37.21 ± 4.12),(34.19 ± 3.98),(34.51 ± 4.52) g/L respectively;F =9.034),((10.45 ± 1.12),(10.17 ± 1.35),(11.32 ± 1.09),(11.46 ± 1.38) mm respectively;F =7.525),((9.58 ± 1.42),(9.47 ± 1.31),(10.71 ± 1.40),(10.15 ± 1.41) mm respectively; F =4.963) and ((63.98 ± 4.73) ％,(63.92 ± 5.17) ％,(60.12 ± 5.12) ％,(61.43 ± 5.57) ％respectively ;F =6.984),and the differences were statistic significant (P ＜ 0.05).Compared to diabetic-H group and non-diabetic-H group,there were significant difference in the terms of all above indexes between diabetic-L group,non-diabetic-L (P ＜ O.05).Conclusion The peritoneal transport.type of diabetic patients is high permeability,which might be an important factor affecting cardiac complications in patients.

OBJECTIVETo observe the clinical effect of unblocking the interior and purgation method on improving decreased gastrointestinal motility of post-operative esophageal cancer patients, and to study its mechanisms.

METHODS60 patients with post-operative esophageal cancer were randomly assigned to two groups, the treatment group and the control group, 30 in each group. Routine therapies were given to the two groups. Chinese drugs with unblocking the interior and purgation action was infused by enteral nutrition tube to patients in the treatment group, while normal saline was infused to those in the control group. The first flatus time, the first defecation time, the bowel tones recovery time after operation, and the total amount of the gastric juice draining between the first day and the third day after operation of all patients were recorded. Plasma motilin (MTL) and vasoactive intestinal peptide (VIP) contents were detected before operation and the fourth day after operation.

RESULTSThe first flatus time, the first defecation time, the bowel tones recovery time after operation, and the total amount of the gastric juice draining were less in the treatment group than in the control group, showing statistical difference (P<0.05, P<0.01). The post-operative MTL contents were higher and VIP contents lower in the treatment group than in the control group, showing statistical difference (P<0.05, P<0.01). There was no significant difference in plasmal MTL and VIP contents of the treatment group between before and after treatment (P>0.05). But there was significant difference in plasmal MTL and VIP contents of the control group between before and after treatment (P<0.01).

CONCLUSIONUnblocking the interior and purgation method could significantly promote the gastrointestinal motility recovery of post-operative esophageal cancer patients, showing good clinical effect.
