Objective To evaluate the effect of atorvastatin on patients with hepatolithiasis and obstructive jaundice after partial hepatectomy.Methods We retrospectively analyzed the data of 51 patients with hepatolithiasis and obstructive jaundice who were treated with partial hepatectomy from July 2006 to August 2015 at Xishan People's Hospital of Wuxi.Based on whether atorvastatin was used or not,the patients were divided into the treatment group (25 patients) and the control group (26 patients).Liver function tests were determined regularly after operation.The serum liver function on postoperative day 3 (P3d) and postoperative day 5 (P5d),complications (incisional infection,abdominal infection,pleural effusion,peritoneal effusion and bile leakage) and duration of hospital stay in the two groups of patients were compared.Results There was no perioperative death in the two groups.When compared with the control group,liver function data suggested an improvement in the treatment group,as ALT and AST in the treatment group were significantly lower than in the control group on P3d and P5d [ALT (252.6 ± 87.0) U/L vs (385.0 ± 152.9)U/L,(89.9 ±28.2) U/L vs (116.9 ±29.3) U/L;AST(130.7 ±66.9) U/L vs (212.7 ±80.0) U/L,(47.5 ± 16.1) vs (69.2 ± 12.2) U/L,all P ＜ 0.05].When compared with the control group,the serum cholesterol level was lower on P3d and P5d [TC:(6.7 ± 0.3) mmol/L vs (6.2 ± 0.3) mmol/L;(6.1 ± 0.4) mmol/L vs (7.0 ± 0.4) mmol/L,P ＜ 0.05],the serum CRP level was also lower in the treatment group [(56.8 ± 15.7) mg/L vs (98.9 ± 40.3) rg/L,P ＜ 0.05];the duration of hospital stay was (10 ± 1) days in the treatment group,which was significantly different from the control group (12 ± 1) days.Conclusion The use of atorvastatin in patients with hepatolithiasis and obstructive jaundice who were treated with partial hepatectomy improved postoperative liver function and shortened postoperative hospital stay.

Objective To clarify the association of pre-existing choledocholithiasis or cholecystolithiasis and the development of intrahepatic cholangiocarcinoma(ICC).Methods A computerized literature search was performed in Pubmed,EmBase and CBM.Cohort and case control studies on the risk of choledocholithiasis or cholecystolithiasis developing ICC was included.Meta-analysis was performed using STATA version 12.0.Either a fix or random effect model was used according to heterogeneity among studies.Egger's test was performed to assess publication bias.Results A total of 6 case control studies fulfilled our inclusion criteria including 123,713 patients,4,753 for ICC and 118,960 for tumor free controls.Bile duct stone contributed to the development of ICC (OR:15.64,95％ CI 9.33-26.23).Apart from hepatolithiasis,there was still a high risk of ICC development for choledocholithiasis (OR:11.05,95 ％ CI:4.02 ～ 30.37).Cholecystolithiasis is also a risk factor for ICC (OR:2.35,95 ％ CI:1.28 ～ 4.31).Conclusion Both choledocholithiasis and cholecystolithiasis are important prognostic factors for ICC.

【Objective】 To analyze the gene expression profile of central nervous system primitive neuroectodermal tumors （CNS-PNETs） by bioinformatics methods so as to explore the possible pathogenesis of CNS-PNETs at the molecular level. 【Methods】 The gene expression profile of CNS-PNETs was downloaded from the GEO database， GSE35493 and GSE74195. The differentially expressed genes （DEGs） were screened by the online analysis tool of GEO2R and Venn software， DEGs were analyzed by using the online analysis tools of David database， such as Gene Ontology （GO） and pathway enrichment （KEGG）. The protein interaction network analysis （PPI） of CNS-PNETs was made by using STRING online analysis tool， Cytoscape software and its plug-in cytohubba to find the key genes. 【Results】 We obtained 262 DEGs， including 49 upregulated genes and 213 downregulated genes. The analysis of GO function and KEGG signal pathway enrichment showed that DEG was involved in DNA transcription and mitosis， cell division， synaptic signal transmission and other biological processes， and associated with cell cycle， tumor-related pathway， p53 signal pathway， synapsis-related signal pathway， cAMP signal pathway and calcium ion signal pathway. Ten key genes， namely， CDK1， CDC20， MAD2L1， KIF11， ASPM， TOP2A， TTK， NDC80， NUSAP1 and DLGAP5 were screened out by STRING analysis. 【Conclusion】 Ten key genes including CDK1 may play an important role in the initiation and progression of CNS-PNETs， providing new clues for exploring the pathogenesis of CNS-PNETs.
