The risk factors,especially laboratory indicators,of prognosis after acute kidney injury (AKI) remain unclear.We conducted a retrospective survey of Chinese People's Liberation Army General Hospital from January 1,2012 to December 31,2012 according to the AKI diagnosis standard issued by Kidney Disease Improving Global Outcomes.The epidemiological features and factors influencing hospital mortality and renal function recovery were evaluated through logistic regression analysis.Among 77 662 cases of hospitalized patients,1387 suffered from AKI.The incidence rate and mortality of AKI were 1.79％ and 14.56％,respectively.Multivariate logistic regression analysis revealed that high AKI stage,age greater than 80 years,neoplastic disease,low cardiac output,increased white blood cell count,and decreased platelet count and serum albumin levels were the risk factors affecting the mortality of AKI patients.Conversely,body mass index between 28 and 34.9 was a protective factor.Increased AKI stage,tumor disease,post-cardiopulmonary resuscitation,and RRT were the risk factors of renal function recovery upon discharge.In addition to traditional risk factors,white blood cell count,platelet count,albumin,and BMI were the predictors of the mortality of AKI patients.No laboratory indicators were found to be the risk factors of renal function recovery in AKI patients.

Objective:To investigate the effect of gold microneedle and subcutaneous apocrine excision in the treatment of bromidrosis and the occurrence of postoperative complications.Methods:From July 2019 to November 2020, 42 patients (13 males and 29 females; 16-47 years old, average 23 years old) were treated with plastic surgery in the First Affiliated Hospital of Xinjiang Medical University, 20 patients received gold microneedle treatment, and 22 patients received minimally invasive surgery (subcutaneous apocrine excision surgery). The patients were followed up for 3-6 months after operation, and the severity of preoperative bromidrosis, postoperative curative effect and occurrence of postoperative complications were compared between the two groups.Results:Eighteen cases were effective in the gold microneedle group, accounting for 90%; 22 cases were effective in the minimally invasive surgery group, accounting for 100%; the difference between the two groups was statistically significant ( P<0.05). There was a negative correlation between the grade of bromidrosis before operation and the curative effect after operation in the gold microneedle group, and the correlation coefficient was not statistically significant in the minimally invasive operation group ( P>0.05). Complications occurred in 4 cases in the gold microneedle group, accounting for 20.0%; 10 cases presented with complications in the minimally invasive surgery group, accounting for 45.5%; the difference was statistically significant ( P<0.05). Conclusions:The therapeutic effect of gold microneedle is lower than that of minimally invasive surgery, and the higher the degree of bromidrosis, the worse the curative effect. The postoperative complication rate of gold microneedle treatment for bromidrosis is lower than that of minimally invasive surgery.

OBJECTIVE To e stablish the fingerprint of Qings hen tiaozhi xiaoke tablets （QTXT）and carry out the analysis of chemical pattern recognition ，and determine the contents of seven active components simultaneously. METHODS Using coptisine hydrochloride as reference ，the Similarity Evaluation System for Chromatographic Fingerprint of TCM （2012 edition）was utilized to establish the HPLC fingerprints of 13 batches of QTXT and analyze their similarity. The common peaks were confirmed by comparing with the chromatogram of the mixed control ；the attribution of the common peak was determined by comparing the chromatograms of the sample solutions of single decoction pieces and negative sample solutions ；using SPSS 22.0 and SIMCA 14.1 software，cluster analysis （CA），principal component analysis （PCA）and orthogonal partial least squares-discriminant analysis （OPLS-DA）were carried out ，and the markers affecting the quality of QTXT were screened ，using the variable importance in projection（VIP）value greater than 1 as the standard. Using coptisine hydrochloride as internal reference ，the contents of naringin ， hesperidin，neohesperidin，berberine hydrochloride ，palmatine hydrochloride and lovastatin were determined by quantitative analysis of multicomponents by single marker （QAMS），and then compared wi th the result s（except for coptisine hydrochloride ） of external standard method.

Peaks 7-10 were the exclusive peaks of Coptis chinensis ；peaks 3-6 and 11-13 were the exclusive peaks of bran-fried Fructus aurantii ；peak 14 was the exclusive peak of Monascus purpureus ；peak 1 was the common peak of C. chinensis and M. purpureus . Peak 2 and 15 were the common peak of bran-fried F. aurantii and M. purpureus ；peaks 16 and 17 were the common peaks of 6 traditional Chinese medicines. The results of CA showed that 13 batches of QTXT could be divided into three categories ，S2 was clustered into one category ，S1，S9，S10 were clustered into one category ，S3-S8 and S 11-S13 were clustered into one category. The results of PCA showed that accumulative variance contribution of the first three principal components was 85.120％. Compared with CA ，S1 was further distinguished from S9 and S 10 by PCA. OPLS-DA showed that 7 common peaks with VIP value greater than 1（from large to small ）were peak 10 （berberine hydrochloride ），peak 9（palmatine hydrochloride ），peak 5（hesperidin），peak 11 and peak 8（coptisine hydrochloride ）， peak 12 and peak 6（neohesperidin）. The contents of naringin ，hesperidin，neohesperidin，berberine hydrochloride ，palmatine hydrochloride and lovastatin measured by QAMS were 40.198-77.552，6.138-13.413，71.823-125.868，11.274-49.951，3.303- 5.367，1.821-3.185 mg/g，respectively. The contents of naringin ，hesperidin，neohesperidin，berberine hydrochloride ，coptisine hydrochloride，palmatine hydrochloride and lovastatin measured by external reference method were 41.454-79.976，6.404-13.993， 74.068-129.081，11.627-51.512，5.922-12.020，3.158-5.131 and 1.901-3.325 mg/g，respectively. The deviations of the two methods （except for coptisine hydrochloride ）were all less than 3.00％. CONCLUSIONS The established HPLC fingerprint and the method of QAMS are simple ，accurate and reproducible. Combined with chemical pattern recognition analysis ，it can be used for the quality evaluation of QTXT. Berberine hydrochloride ，palmatine hydrochloride and other components may be the markers affecting the quality of the drug.
