Nonalcoholic fatty liver disease(NAFLD)has become one of the most common liver diseases in the world.Considering the important role of insulin resistance in its pathogenic mechanisms,insulin sensitizers are becoming the promising pharmacological strategies for NAFLD.We collected and analyzed the relevant articles in recent years and found that pioglitazone,rosiglitazone and metformin could improve liver enzymes and insulin sensitivity of NAFLD.However,only pioglitazine was supported in ameliorating liver histology by envidences from randomized,double-blinded,controlled clinical trials.There were no much obvious adverse effects in NAFLD patients who received insulin senitizers.Small or medium samples and no more than 2 years of treatment course may be the major limitation of current studies.Future information derived from well-designed running trials will be useful in defining the clinical implications of insulin sensitizers in the treatment of NAFLD.

Objective To investigate the effect of hypoxia micro?environment on anoikis in human high?metastatic cell line 95D of giant cell carci?noma of lung. Methods Suspension technology was used to culture 95D to establish the model of anoikis?resistant 95D cells. Hypoxic culture was conducted in the experimental group,and regular culture was conducted in the control group. The effect of hypoxia on proliferation of anoikis?resis?tant 95D was investigated by MTT and the apoptosis in the two groups were detected by flow cytometer. The invasive ability of the cells was assessed by Transwell test. The effect of hypoxia on the expression of HIF?1α,VEGF and MMP?2 in anoikis?resistant 95D was detected by Western blot. Re?sults The growth rate of the anoikis?resistant 95D cells treated with hypoxia was 52.9%,and the apoptosis rate of these cells was higher than that in the non?hypoxic group(40.4%vs 21.7%,P<0.05). The treatment of hypoxia down?regulated the invasive ability,the number of migration cells un?der hypoxia was higher than that in the control group,with statistical significance(40.1±6.7 vs 12.5±7.9,P<0.05). The up?regulation of HIF?1α, the down?regulation of VEGF and MMP?2 were observed in the group of hypoxia. Conclusion During anoikis of human high?metastatic lung can?cer cell line 95D,hypoxia inhibited the survival ability and the metastasis ability of anoikis?resistant cells,which,however,might be the early mani?festation of hypoxia.

Objective To examine the relationship between plasma soluble interleukin 2 receptor(sIL2R), bone metabolism markers, and bone mineral densities in female patients with Graves′ disease(GD), and to explore the role of sIL2R in bone metabolism of GD.Methods This study included 201 female GD patients.FT3, FT4, TSH, PTH, osteocalcin(OCN), C-terminal telopeptides of type Ⅰ collagen (CTX), procollagen type I N-terminal propeptide(PINP), and 25-(OH)-vitamin D(25OHD) were measured using electrochemical luminescence technique.sIL2R was measured using chemiluminescence method.All pations underwent examinations of bone mineral densities at lumbar spine, total hip, and femoral neck(LS-BMD, TH-BMD, and FN-BMD).The associations of sIL2R with bone metabolism markers and bone mineral densities were analyzed.Results OCN,CTX,PINP gradually decreased across the tertile groups of LS-BMD, TH-BMD, FN-BMD(all P<0.05).FT3, sIL2R gradually increased across the tertile groups of OCN, CTX, PINP(all P<0.05).Multiple linear regression analysis showed that sIL2R was independently associated with OCN and CTX(both P<0.05).Conclusion The increase of bone turnover leads to bone loss in female GD patients.The plasma level of sIL2R was positively correlated to bone turnover, which indicated that sIL2R may play an important role in bone metabolism of GD.

Objective To compare between conventional and endoscope-assisted greater saphenous vein harvesting and to invest if endoscope-assisted greater saphenous vein harvesting can reduce post-operative leg incision complications.Methods Minimally invasive endoscopic saphenous vein harsvesting technique has been used in 36 isolated CABG patients and this is compaired with 50 conventional saphenous vein harsvesting group. There is no significant difference in sex structure, age, hypertension, diabetes mellitum (DM), myocardial infarction (MI) et al in two groups. Results The incidence of post-operative leg complications with minimally invasive greater saphenous vein harvesting group (2.8% ) was remarkably lower than that in conventional group (28%), and the hospital-stay time was much shorter in minimally invasive group. Conclusion Endoscope-assisted saphenous vein harvesting is a effective method in reducing post-operative leg incision complications.

Objective To compare the efficacy and tolerability of nateglinide with those of acarbose in Chinese type 2 diabetes mellitus (T2DM) patients.Methods This multi-center,randomized,double-blind,parallel-arm study compared the efficacy and tolerability of nateglinide( 120 mg,3/d,n = 119) and those of acarbose( 100 mg,3/d,n = 118) during a 12-week treatment in T2DM patients uncontrolled by diet with glycosylated haemoglobin (HbA1c) 6.5% - 11.0% .Results Monotherapy with nateglinide (120 mg,3/d)or acarbose (100 mg,3/d)decreased HbA1c to a similar extent during 12-week treatment.The mean change from baseline to end-point in HbAlc was ( -0.90±0.98)% and ( -0.83±0.81 )% in patients receiving nateglinide and acarbose,respectively,with no significant difference between the two groups (P>0.05).The decrease in fasting plasma glucose (FPG)was similar between nateglinide and acarbose (P > 0.05).The mean change in 2-hour postprandial plasma glucose ( PG2h ) was ( - 1.45 ± 2.74) mmol/L and ( -2.20±2.21 ) mmol/L in patients receiving nateglinide and acarbose(P =0.0017).Body weight was significantly decreased in both groups at the end-point ( P < 0.05 ),although the decrease was more with acarbese than nateglinide [( -0.66±1.79)kg vs (-2.06±2.00) kg,P=0.0000].And the proportion of patients experiencing any presumed drug related adverse events was not significantly different between the two groups.Conclusions Nateglinide ( 120 mg,3/d) is effective and well tolerated in T2DM patients uncontrolled by diet,demonstrating similar HbA1c reductions as compared with acarbose (100 mg,3/d).

ObjectiveTo investigate the protective effect of all-trans retinoic acid (ATRA) on injury of human immortalized hepatocytes (HHL-5 cells ) induced by sodium arsenite and possible mechanisms.Methods After cultured for 48 h,HHL-5 cells were divided into four groups:normal group,ATRA group,sodium arsenite group and ATRA + sodium arsenite group.HHL-5 cell viability was tested by using cell proliferation experiment (WST).Superoxide dismutase(SOD),glutathione peroxidase(GSH-Px) activity,malondialdehyde(MDA) content,and aspartate aminottransferase (AST) activity in each group were determined by biochemical method.The microstructure of HHL-5 cells in each group was observed under transmission electron microscopy.ResultsHHL-5 cell viability(0.57 ± 0.02) of sodium arsenite group was compared with that of normal group(0.70 ± 0.01 ),the difference was statistically significant(P ＜ 0.05).Levels of SOD,GSH-Px,MDA and AST[ (153.84 ± 2.35),(0.08 ±0.02)U/mg Prot,(4.15 ± 0.50)nmol/mg Prot,(265.43 ± 4.62) × 103 U/L] of sodium arsenite group were compared with that of normal group[(237.41 ± 18.30),(0.93 ± 0.02)U/mg Prot,(2.26 ± 0.40)nmol/mg Prot,(177 ± 9.85) ×103 U/L],and the difference was statistically significant (all P ＜ 0.05).HHL-5 cell viability (0.65 ± 0.04) of ATRA + sodium arsenite group was compared with that of sodium arsenite group, and the difference was statistically significant (P ＜ 0.05).Levels of SOD,GSH-Px,MDA and AST[ (286.85 ± 3.39),(0.56 ± 0.09)U/mg Prot,(3.36 ± 0.37)nmol/mg Prot, (220.02 ± 1.07) × 103 U/L] of ATRA+ sodium arsenite group were compared with that of sodium arsenite group,the difference was statistically significant(all P ＜ 0.05).Compared with normal group and ATRA group,the surface microvilli of HHL-5 cells of sodium arsenite group decreased,double-membrane structure was unclear,vacuolar degeneration was seen in the cytoplasm,and glycogen was aggregated.The damage level of ATRA + sodium arsenite group was decreased.ConclusionsATRA plays a protective role through increasing intracellular antioxidant enzyme activity of HHL-5 cells,removal or reduction of oxygen free radicals produced by sodium arsenite.

Objective To observe the influences of different doses of sodium arsenite on mRNA transcription of keratinizing related and nuclear factor E2-related factor 2(Nrf2) genes in HaCaT cells.Methods Cell proliferation was evaluated by Cell Counting Kit-8(CCK-8) assay after the HaCaT cells were exposed to 0.00,3.13,6.25,12.50,25.00,50.00,75.00,100.00 μ mol/L sodium arsenite for 48 h,respectively.Based on the previous results of cell proliferation,0.00(control),6.25,12.50,and 25.00 μmol/L of sodium arsenite were selected to treat HaCaT cells for 48 h,respectively.The mRNA expression of keratin 1,keratin 10,involucrin,loricrin and Nrf2 were detected by real-time fluorescent quantitative PCR.ResultsCompared with the control group (100.05％),HaCaT cell proliferation rates(83.06％,51.04％,39.52％,24.51％,16.99％ and 9.04％) were significantly lower in 6.25,12.50,25.00,50.00,75.00 and 100.00 μ mol/L of sodium arsenite groups and the 50％ inhibiting concentration was 12.38 μmol/L.Compared with the control group( 1.06 ± 0.28,1.00 ± 0.12,1.00 ± 0.08),the mRNA expression of keratin 1,involucrin and loricrin (0.08 ± 0.04,0.13 ± 0.12,0.05 ± 0.03;0.47 ± 0.11,0.21 ± 0.09,0.10 ± 0.15; 0.50 ± 0.27,0.31 ± 0.10,0.57 ± 0.23) were significantly decreased(all P ＜ 0.05) in HaCaT cells treated with 6.25,12.50,25.00 μmol/L sodium arsenite,respectively.But keratin 10 mRNA expression showed a rise trend and the 6.25 μmoL/L sodium arsenite group (1.83 ± 0.45) was significantly higher than that of the control( 1.07 ± 0.14,P ＜ 0.05 ).The Nrf2 mRNA expressions of HaCaT cells in 12.50,25.00 μmol/L sodium arsenite groups(0.13 ± 0.07,0.69 ± 0.33) were significantly lower than that of the control ( 1.00 ± 0.09,all P ＜ 0.05 ).ConclusionsThe cellular proliferation and keratinization are decreased when HaCaT cells are exposed to sodium arsenite,which may be regulated by lowering Nrf2 mRNA transcription.

Objective To study the association between serum interleukin-33 (IL-33) level and human stromelysin-2 (ST2) level in patients with rheumatoid arthritis (RA) associated with interstitial lung disease (RA-ILD) and its correlation with lung function and other laboratory parameters.Methods Two hundred and forty-five newly diagnosed RA patients during March 2012 to March 2013 in the in-patient and out-patient clinic of the First Affiliated Hospital of Liaoning Medical College were enrolled into this study.Patients were further divided into RA group (n=187) and RA-ILD group (n=58).Sixty subjects who came to the hospital for routine health check-up was composed of the normal control group.The clinical data of the two groups and controls were collected and their serum IL-33 and ST2 concentrations were measured.The t test was used to compare the difference between the two groups.Multiple variance analysis was used to com-pare the difference between groups.Pearson's correlation analysis was applied to explore the relationship between IL-33 concentrations and related variables.Results ① This study showed that the prevalence of RA associated interstitial lung disease was 23.7％(58/245).② The concentration of IL-33 [(746±43) pg/ml] and ST2 [(3413±169)pg/ml] of the RA-ILD group was significantly higher than that of the RA group [(433±42) pg/ml,(1500±147) pg/ml] (P＜0.01).③The vital capacity (VC％),forced vital capac-ity (FVC％),maximal midexpiratary flow curve (MMF％) and carbon monoxide diffusing capacity (DLCO) of the RA-ILD group were significantly lower than those of the RA group.④ The serum level of IL-33 was negatively correlated with that of RF and ACPA (IL-33 and RF,r=0.82,P＜0.01; IL-33 and ACPA,r=0.55,P＜0.01).Serum level of IL-33 was negaitively correlated with DLCO (r=-0.80,P＜0.01).Conclusion IL-33 participates in the pathogenesis of RA; and may be involved in the pathogenesis of RA-ILD.
