[Objective] To investigate the effects of the bioactive constituents of green tea polyphenols epigallocatechin gallate (EGCG) on low density lipoprotein receptor (LDLR) function of HepG2 cells.[Methods] The optimal concentration and cell proliferation of HepG2 cells were determined by CCK8 assay,and Western blotting was used to determine LDLR and PCSK9 protein levels,respectively,and LDL uptake in HepG2 cells was detected by fluorescence microscope.[Results] EGCG elevated LDLR protein expression,reduced PCSK9 protein expression and promoted LDL uptake in HepG2 cells.[Conclusion] EGCG may increase LDLR abundance by down-regulating PCSK9 protein and attenuating LDLR protein degradation,which providing a new approach for lipid lowering therapy.

Objective To examine clusters of anti-nuclear antibodies (ANA) and their associations with clinical features in patients with systemic lupus erythematosus (SLE).Methods It was a retrospective study.113 SLE patients were reviewed from March 2010 to May 2012 in Department of Rheumatology,Jinhua Central Hospital.ANA and specific autoantibodies to 15 kinds of nuclear antigens were tested by indirect immunofluorescence assay (IIF) and line immunoassay (LIA) respectively.Hierarchical clustering method was performed to analyze specific clusters of ANA profiles in SLE.Chi-square tests were used to investigate relationship between antibody clusters and clinical features of SLE.Results The positive rate of LIA for ANA was 97.3％,consistent with IIF method,and the total accordance rate of the both methods was 98.2％.Thirteen kinds of antigen-specific antibodies were detected in SLE patients by LIA.Clustering analysis for these antibodies showed three specific clusters in SLE,Nuc/His/dsDNA cluster (C1),low-Ro/low-La cluster (C2),and Ro/Sm/RNP cluster (C3),accounting for 36.3％,24.8％,38.9％ of the total cases respectively.There were significant difference of AST levels among three clusters [(32.62 ± 21.92)U/L,(25.56 ± 16.63) U/L,(50.41 ± 60.86) U/L respectively for C1,C2 and C3].High incidences of chronic cutaneous lupus,abnormal renal indicators and inflammatory synovitis were found in all three clusters.Besides,there were significant differences among three clusters for the incidences of chronic cutaneous lupus (39.0％,39.3％,63.6％ respectively for C1,C2,C3) and leukopenia/lymphopenia (56.1％,25.0％,56.8％ respectively for C1,C2,C3) (P ＜ 0.05).Patients in Ro/Sm/RNP cluster showed higher incidences of lupus nephritis (43.2％/26.8％ or 39.3％); patients in low-Ro/low-La cluster showed low risk of hypertension (7.1％/19.5％ or 22.7％) ; patients in Nuc/His/dsDNA cluster showed high incidences of thrombocytopenia (41.5％/21.4％ or 25.0％) and high risk of lung or upper respiratory tract infection (46.3％/28.6％ or 29.5％),but low incidence of neurologic symptoms (0％/ 3.6％ ％ or 11.4％).Conclusion Three characterized ANA clusters are identified in SLE patients in this pilot study.Different clusters are associated with certain clinical features and complications ofSLE.However,the correlations found in this study need to be investigated further in larger populations.

Objective:To evaluate the efficacy and safety of rosuvastatin and atorvastatin in the treatment of the patients with primary hyperlipidemia in China.Methods:The related literatures in CNKI,VIP,Wanfang medicine network,PubMed/MEDLINE,CBM and Chinese dissertations full text database were retrievaled by computer from the establishment time of database to December 31,2015. Two researchers according to the inclusion and exclusion criteria independently selected the studies and extracted the data and assessed the quality of the literatures.The Revman 5.0 software was used to perform Meta analysis of all effect indicators in various groups.Results:A total of 7 randomized controlled trial (RCT)were included,and there was no significant abnormality in bias evaluation. 8 weeks after treatment, the total cholesterol (TC), triglyceride (TG), low density lipoprotein cholesterol (LDL-C)and high density lipoprotein cholesterol (HDL-C)levels of the patients in 5 mg rosuvastain group and 10 mg atorvastatin group had no significant differences between before and after treatment (P >0.05);the HDL-C levels of the patients in 10 mg rosuvastatin group and 10 mg atorvastatin group had significant differences between before and after treatment (P < 0.05),but the TG,TC,and LDL-C levels had no significant differences (P >0.05);the TG,TC,LDL-C and HDL-C levels of the patients in 5 mg and 10 mg rosuvastatin groups had no significant differences between before and after treatment (P > 0.05).12 weeks after treatment,there were no significant differences in the TC and LDL-C levels between 10 mg rosuvastatin group and 10 mg atorvastatin group (P >0.05),but there were significant differences in the TG and HDL-C levels (P <0.01).The incidence of adverse reactions of the patients in three groups had no significant differences (P >0.05).Conclusion:5 mg rosuvastatin and 10 mg atorvastatin in the treatment of the patients with primary hypercholesterolemia have similar lipid-lowering effect;with the the increase of the treatment time and the dose,10 mg rosuvastatin can obviously reduce the TG level and increase the HDL-C level of the patients,and the incidence of adverse reactions of two kinds of doses of rosuvastatin has no obvious difference.

Objective To explore the effect of uremic serum on apoptosis in human umbilical vein endothelial cells(HUVECs) and the intervention by recombinant human erythropoietin(rhEPO) in this process.Methods From Dec.2008 to Apr.2009,10 uremic patients and 10 healthy volunteers were enrolled in this study.HUVECs were divided into 3 groups:control group(including 10% healthy serum medium),uremic group(including 10% uremic serum medium) and rhEPO treatment group(rhEPO at 5,10 or 15 U/ml was added to 10% uremic serum medium).After 24 hous's intervention,cell apoptosis was evaluated by TUNEL assay,and reactive oxygen species were detected by colorimetry.Results HUVECs apoptosis index and ROS level were higher in the presence of uremic serum than those of healthy serum(P

OBJECTIVE To investigate the distribution and antibiotic resistance of nonfermenting gram-negative bacilli isolated from lower respiratory tract infection patients from 2003 to 2007 for rational antimicrobial therapy in practice.METHODS The data of distribution and antibiotic resistance of nonfermenting gram-negative bacilli isolated from sputum samples of lower respiratory tract infection in our hospital from 2003 to 2007 were retrospectively analysed.RESULTS The most predominant nonfermenting gram-negative bacilli isolates were Pseudomonas aeruginosa,Acinetobacter baumannii,Acinetobacter lwoffii and Stenotrophomonas maltophilia.From 2003 to 2007,the resistance rates of these isolates to 15 antibiotics increased,especially P.aeruginosa to ceftazidime.The resistance changed from 30.2% in 2003 to 55.4% in 2005,54.8% in 2006,and reduced to 41.5% in 2007.The resistance to gentamicin,imipenem,netilmicin,ticarcillin and tobramycin varied in the similar way.The resistance of A.baumannii to imipenem increased from 21.1% to 59.7% within the five years.The resistance rate of A.lwoffi was still relatively low.S.maltophilis isolates were highly multi-resistant to antimicrobial agents tested with a rate ranging from 61.9%-100.0% except ceftazidime,ticarcillin and trimethoprim-sulfamethoxazole.CONCLUSIONS P.aeruginosa,A.baumanii and S.maltophilia are the main nonfermentive pathogens of lower respiratory tract infections and not susceptive to many antibiotics.The tendency of susceptibility and distribution changes of those bacteria should be considered in practice for proper antimicrobial therapy.
