Objective:To establish the quality standard for Chuipencao tablets. Methods:Sedum sarmentosum Bunge was identi-fied by TLC. Quercetin, kaempferol and isorhamnetin were determined by HPLC. Results: The method of TLC was highly specific. The linearity was obtained within the range of 4.94-98.82 μg·ml-1(r =0.999 9) for quercetion, 4.94-98.82 μg·ml-1(r =0.999 9) for kaempferol and 1.07-21.36 μg·ml-1(r=0.999 9) for isorhamnetion. The average recovery was 103.1%(RSD =2. 2%,n=6), 100. 6%(RSD=2. 0%,n=6) and 100. 1%(RSD=2. 0%,n=6), respectively. Conclusion: The method is accu-rate with good reproducibility, which can be used as the quality control for Chuipencao tablets.

Objective To discussed application effect of modified flowchart of preoperational articles in the operating room. Methods A group for the reconstructed flowchart was set up to look into the problems of traditional flowchart for articles preparation and then have the flowchart modified upon the found problems. The duration for article preparation and the flaw rate were compared between pre-and post-modification. Result The duration for preparation after modification was significantly shorter than that before modification and the flaw rate was significantly lower as well (P<0.001). Conclusion The modified flowchart for article preparation in the operation room can reduce the flaw rate and shorten the duration for article preparation, thus ensuring smooth operation.

Objective To examine the correlation of serum neutrophil gelatinase-associated lipocalin (NGAL) with dialysis adequacy,microinflammatory state and iron metabolism,and to assess the value of NGAL in identifying the dialysis adequacy in maintenance hemodialysis (MHD) patients.Methods A total of 150 MHD patients and 50 healthy control people were enrolled in the study.Clinical data were collected and serum NGAL,CRP,transferrin saturation,serum ferritin were measured.MHD patients were divided into adequacy group and non-adequacy group according to spKt/V value.Serum NGAL between two groups was compared and correlation of NGAL with spKt/V,inflammatory factors,and other clinical indexes was examined by Pearson,multivariate regression Logistic model and area under curve (AUC) of ROC.MHD patients were followed up for 3 months.Similar correlation analysis was carried out before and after follow up between two groups.Results Serum NGAL of MHD patients was higher compared to healthy people [(445.45±50.34) μg/L vs (50.02 ±6.45) μg/L].Among 150 MHD patients,95 were classified into adequacy group,while 55 into non-adequacy group according to spKt/V value.Serum NGAL was significantly higher in adequacy group as compared to non-adequacy group [(589.14±56.34) μg/L vs (360.13±46.23) μg/L,P<0.05].Serum NGAL was positively correlated to spKt/V,CRP,TSAT [r=0.652,0.825,0.785,all P<0.05],but not to serum ferritin.Serum NGAL was also correlated to spKt/V,CRP,TSAT by multivariate regression Logistic model.AUC showed that NGAL level could reflex the condition of dialysis adequacy.During the follow up,all adequacy patients remained the same adequacy status.Thirty-eight out of 55 non-adequacy patients were qualified for complete adequacy after intervention.The serum NGAL before and after intervention was (368.14±56.21) μg/L and (360.56±46.23) μg/L respectively without significant difference.Conclusions Serum NGAL is obviously higher in MHD patients with dialysis adequacy compared to those without dialysis adequacy.Serum NGAL is positively correlated to spKt/V,CRP,TSAT.NGAL can reflex the condition of dialysis adequate in MHD patients.

Objective To summarize the common types and clinical characteristics of ureter disease;which can increase manipulation difficulties and adverse events during rigid ureteroscopic procedures. Methods From Jan 2001 to Dec 2010,our team performed 317 rigid ureteroscopic Drocedures for ureteroscopic examination or treatment;including 60 difficult procedures(34 male and 26 female).The mean age of the patients was 37 years (range,18 to 71).The ureteral diseases were classifted into five types according to the pathological characteristics:Type Ⅰ calculous stenosis,Type Ⅱ neoplastic stenosis;Type Ⅲ non-congenital stenosis,Type Ⅳ congenital stenosis,Type Ⅴ expansion of tortuous ureters.The operative time,complications,and conversion to open surgery were evaluated,and the therapeutic methods were analyzed. Results Of the 60 difficuhly-manipulated procedures,the mean manipulated time was 75 min (range,31 to 200).Intra-operative complications occurred in 9 procedures,including 4 cases of mucosal bleeding,2 cases of submucosaI false passage and 3 cases of ureteral perforation.Eleven procedures were converted to open surgery. In five procedures only a double J tube was inserted for drainage due to the difficulty of entering the ureter.Fiftyfive patients were followed up for 17 months (range,3 to 110);48 patients were cured,5 patients improved and 2 patients were unchanged. Conclusions The five types of ureteral disease can increase operative difficulties and risks of rigid ureteroscopic procedures.We should be cautious during surgery and should stop manipulation or convert to other surgeries if necessary.
