Objective To investigate the incidence and risk factors of acute kidney injury (AKI) after cardiopulmonary bypass(CRB) in children with non cyanotic congenital heart disease. Methods A total of 150 children who underwent cardiopulmonary bypass operation from 2012 May to 2014 May were analyzed retrospectively. The patients were divided into two groups:AKI group (n=29) and non AKI group (n=121). Clinical data were collected and compared between two groups, including gender, age and baseline serum creatinine level. Multivariate Logistic regression analysis was used to evaluate the risk factors for AKI after operation. Results There was no death in the 150 cases. Comparison between groups, there were significant differences in age, history of heart failure and (or)pneumonia, baseline serum creatinine level, baseline uric acid, body mass, CPB) time, aortic clamping time, mechanical ventilation time, postoperative transfusion and hypotension. Multivariate Logistic regression analysis showed that age (≤1 years old), the history of pneumonia and (or) heart failure, CPB time (＞40 min), aortic clamping time (＞30 min) were the independent risk factors for AKI after operation. Conclusion It is important to choose the best age for surgery in children, actively prevent preoperative complications and shorten the CPB and aorta blocking time for preventing the occurrence of AKI.

OBJECTIVETo observe the effect of Zhenqing Recipe (ZQR) on non-alcoholic fatty liver (NAFL), and the expression of hepatic salt-inducible kinase 1 (SIK1) and sterol-regulatory element binding protein-ic (SREBP-lc) in type 2 diabetes rats.

METHODSA rat model of type 2 diabetes was established by high fat/sucrose diet combined with intraperitoneal injection of small dose streptozotocin (STZ) . Modeled rats were randomly divided into the model group, the ZQR group, and the metformin group, 8 in each group. Eight rats were recruited as a normal control group. ZQR at the daily dose of 12 g crude drugs/kg was administered to rats in the ZQR group by gastrogavage. Metformin suspension at the daily dose of 150 mg/kg was administered to rats in the metformin group by gastrogavage. Equal volume of distilled water was administered to rats in the normal control group and the model group. All medication lasted for 12 weeks. The levels of fasting blood glucose (FBG), free fatty acid (FFA), serum triglyceride (TG), serum total cholesterol (TC), serum alanine aminotransferase (ALT), and aspartate aminotransferase (AST) were detected. The body weight and wet liver weight were weighed, and the liver weight index calculated. The liver TG content was measured. The pathological changes of liver and the expression of SIK1 were observed by HE staining and immunohistochemistry. The mRNA and protein expression of SIK1 and SREBP-1c were detected using RT-PCR and Western blot.

RESULTSCompared with the normal control group, FBG, FFA, TG, TC, ALT, AST, liver weight index, and liver TG contents significantly increased (P < 0.01); liver steatosis was severe, the mRNA and protein expression of SIK1 obviously decreased (P < 0.01); mRNA and protein expression of SREBP-1c increased (P < 0.01). After drug therapy, compared with the model group, FBG, FFA, TG, TC, ALT, AST, and liver weight index significantly decreased, liver TG contents significantly decreased, the mRNA and protein expression of SIK1 obviously increased, while mRNA and protein expression of SREBP-1c obviously decreased (P < 0.05, P < 0.01) in the ZQR group and the metformin group (P < 0.05, P < 0.01); and the pathological changes were also improved. All the indices were improved more in the ZQR group (all P < 0.05).

CONCLUSIONIn this experiment, we found that the expression of SIK1 decreased in NAFL rats with type 2 diabetes. ZQR could alleviate lesion of NAFL type 2 diabetes rats possibly by up-regulating hepatic SIK1 expression at mRNA and protein levels.

Objective To investigate the possible origin of ovarian epithelial inclusions and its relationship with the low-grade ovarian serous carcinoma.Methods By comparatively evaluating the morphologic (secretory and ciliated cell distribution ) and immunophenotypic [using paired box gene 8 (PAX8),tubulin,calretinin,and Ki-67 as first antibodies] attributes of ovarian epithelial inclusions,the normal tubal epithelium,and the ovarian tumors,all adnexal tissues from a total of 198 patients were studied,including 116 adnexae removed for non-neoplastic indications,53 serous cystadenomas,44 serous borderline tumors,and 41 low-grade serous carcinomas,which were collected from Qilu Hospital of Shandong University and University of Arizona in USA.Immunohistochemical single staining was used to detect the expressions of PAX8,tubulin,calretinin,and Ki-67 in the two groups,while immunohistochemical double staining of PAX8/calretinin was used to figure out the immunophenotype of various ovarian epithelial inclusions in a more intuitive way.Results With immunohistochemical single staining of PAX8 and calretinin,the vast majority (90％,54/60) of ovarian surface epithelia displayed a mesothelial phenotype [calretinin(+),PAX8 (-)],whereas 10％ (6/60)of the cases displayed foci with tubal phenotype [calretinin(-),PAX8 (+)].In contrast,most (79％,728/921 ) of the ovarian epithelial inclusions displayed a tubal phenotype,though 21％ (193/921) of the ovarian epithelial inclusions showed a mesothelial phenotype.It was further proved by immunohistochemical double staining of PAX8/ calretinin.Secretory and ciliated cells were found in the ovarian epithelial inclusions with tubal phenotype.There was a progressive increase in the secretory/ciliated cells ratio and proliferative index,from ovarian epithelial inclusions/cystadenomas to borderline tumors to low-grade serous carcinoma,according to the expression of tubulin and Ki-67.Conclusions The findings make a strong argument that the ovarian epithelial inclusions displaying a tubal phenotype with PAX8 (+),calretinin (-) is likely derived from fallopian tube rather than through Mullerian metaplasia from ovarian surface epithelium.The increasing trend of secretory/ciliated cells ratio and proliferative index from ovarian epithelial inclusions/cystadenomas to borderline tumors to low-grade serous carcinoma indicates that the latter is a clonal expansion of secretory cells.Genetic and molecular studies are needed to further confirm these findings.

Orthogonal combination design was adopted in examining the Spirulina platensis (S. platensis) yield and the influence of four factors (Se content, Se-adding method, S content and NaHCO3 content) on algae growth. The results showed that Se content, Se-adding method and NaHCO3 content were key factors in cultivation conditions of Se-enriched S. platensis with the optimal combination being Se at 300 mg/L, Se-adding amount equally divided into three times and NaHCO3 at 16.8 g/L. Algae yield had a remarkable correlation with OD560 and floating rate by linear regression analysis. There was a corresponding relationship between effects of the four factors on algae yield and on OD560, floating rate too. In conclusion, OD560 and floating rate could be served as yield-forming factors.
