Objective To analyze the risk factors of acute kidney injury after orthotropic liver transplantation for adult benign end-stage liver disease.Methods A retrospective analysis was conducted in 30 recipients (18 males,12 females,aged 23-68 years,ASA grade Ⅲ or Ⅳ) who underwent orthotropic liver transplantation for benign end-stage liver disease at Tongji Hospital from May,2014 to December,2014.Both demographic characteristics and perioperative parameters were collected,including general condition,surgery and anesthesia factors and intraoperative salvage autotransfusion or not.Perioperative laboratory findings related to renal function including urine volume,serum creatinine (Scr) and urea nitrogen (BUN) were collected,too.All variables tested in the univariate analysis with a P<0.10 were included in a multiple logistic regression analysis.Results There were less intraoperative salvage autotransfusion,more platelet transfusion and a higher using rate of vasopressors in the AKI group after surgery than those did not.Patients who received intraoperative salvage autotransfusion had 0.058 time odds (95%CI 0.005-0.649) of AKI than those did not;patients who required platelet transfusion had 10.706 times higher odds (95%CI 1.212-94.963) of AKI than those did not.Conclusion It is likely that intraoperative salvage autotransfusion was able to decrease the morbidity of AKI,while platelet transfusion and vasopressor administration to maintain blood pressure could increase the possibility of AKI.

OBJECTIVE：To provide reference for the identification and proces sing end-point determination of raw Morus alba and its processed products （honey-processed M. alba ）. METHODS ：UPLC method was adopted. The determination was performed on Waters BEH Shield RP C 18 column with mobile phase consisted of acetonitrile- 0.1％ phosphoric acid solution （gradient elution ） at the flow rate of 0.30 mL/min. The column temperature was set at 30 ℃. The program wavelengths were set at 280 nm（0-4 min） and 320 nm（4-35 min）. Similarity Evaluation System for Chromatogram Fingerprint of TCM （2012 edition）was used to establish UPLC fingerprint and carry out similarity evaluation of 13 batches of M. alba and honey-processed M. alba . The chromatographic peaks were identified with reference substance fingerprint. The colorimetric value （L，a，b） of 13 batches of M. alba and honey-processed M. alba powder were determined ，and average total colorimetric value （E）was calculated. OPLS-DA and cluster analysis were adopted to analyze the differences in fingerprints and colorimetric values of M. alba before and after processing. At the same time ，the dynamic change rule of fingerprint and colorimetric value of honey-processed M. alba at different processing time points were analyzed to determine the processing end-point. RESULTS ：There were obvious differences in fingerprints before and after processing ，and the similarity of 13 batches of M. alba and honey-processed M. alba were all higher than 0.9. Totally 21 common peaks were calibrated for M. alba ，and 23 common peaks for honey-processed M. alba ；peak 1 and peak 2 were newly produced compounds of honey-processed M. alba . Peak 2，peak 7，peak 14 and peak 19 were identified as 5-hydroxymethylfurfural， mulberry glucoside A ，oxidized resveratrol ，mulberry flavonoids G. Results of OPLS-DA showed that the peak area-sample quantity ratio of peak 1，peak 2，peak 18，peak 20 and the chromaticity values （L，a，b）were the most important factors affecting the difference of raw and processed products of M. alba . When the E ranged 75.84-80.88 as the processing end-point of honey-processed M. alba ，the processing time was determined as 22-34 min. CONCLUSIONS ： The established UPLC fingerprint and colorimetric value determination method can be used to identify the raw and processed products of M. alba as well as determine the processing end-point of honey-processed M. alba .

OBJECTIVE：To establish the UPLC fingerprint of Polygonum cuspidatum ，and to determine the contents of four active ingredients and to provide reference for the quality evaluation of P. cuspidatum . METHODS ：The determination was performed on Waters BEH C 18 column（100 mm×2.1 mm，1.7 μm）with mobile phase consisted of acetonitrile- 0.2％ formic acid （gradient elution ）at flow rate of 0.4 mL/min. The column temperature was 40 ℃，and detection wavelength was 290 nm. The sample size was 1 μL. The fingerprints were evaluated by similarity calculation，cluster analysis and orthogonal partial least square discriminant analysis （OPLS-DA）. Using polydatin as internal standard ，relative calibration factors of resveratrol ，emodin-8-O- β-D-glucoside and emodin were determined to develop a method of QAMS. The contents of 4 above components in 15 batches of P. cuspidatum were calculated by relative calibration factors. The results of QAMS were compared with those of external standard. RESULTS：UPLC fingerprints of 15 batches of P. cuspidatum were established ，and 12 common peaks were confirmed. Five components were identified ，i.e. polydatin ，resveratrol，emodin-8-O-β-D-glucoside，emodin，emodin methyl ether. The fingerprint similarity of 15 batches of P. cuspidatum was in the range of 0.865-0.976. According to cluster analysis ，15 batches of P. cuspidatum were classified into 4 categories，showing certain regularity of origin. Seven markers were identified by OPLS-DA method. The order of difference significance was peak 7＞emodin-8-O-β-D-glucoside＞resveratrol＞peak 8＞polydatin＞peak 1＞ peak 10. The relative deviation among the contents of resveratrol ，emodin-8-O-β-D-glucoside and emodin in 15 batches of P. cuspidatum determined by QAMS and external standard method was less than 5.0％，indicating that there was no significant difference between the two methods. CONCLUSIONS ：UPLC fingerprint combined with QAMS method is convenient and reliable for the quality evaluation of P. cuspidatum ；the quality of P. cuspidatum produced in Chongqing and Anhui province is better.
