ObjectiveTo study the effect of nutritional intervention combined with aerobic exercises on serum adiponectin and insulin resistance in nonalcoholic fatty liver (NAFL) patients.Methods32 patients confirmed as NAFL between April 2008 and August 2009 were enrolled into NAFL group and 31 health people into control group.NAFL group received nutritional intervention and followed aerobic exercise program.The changes of body mass index (BMI),serum adiponectin,fasting blood glucose (FBG),fasting insulin (FINS) and serum lipids were recorded before and after interventions.Insulin resistance index (HOMA-IR) was calculated.Inter-group difference,changes after intervention,and correlation between serum adiponectin and the other indexes were analyzed.ResultsCompared with the control group,BMI [ (29.84 ±3.16) kg/m2 vs.(22.22 ± 1.81 ) kg/m2,P =0.000],total cholesterol (TC) [ (5.09 ±0.86) mmol/L vs.(4.38 ±0.85) mmol/L,P =0.002],triglyceride (TG) [ (1.99±0.86) mmol/Lvs.(1.10±0.38) mmol/L,P=0.000],FBG[ (6.02±0.63) mmol/Lvs.(5.02±0.71) mmol/L,P=0.000],FINS[ (13.73±3.24) mU/Lvs.(9.55±1.99) mU/L,P=0.000],HOMA-IR [ (3.74±1.21) mmol/L vs.(2.08 ±0.27) mmol/L,P=0.000] in the NAFL group were significantly higher,while serum adiponectin in the NAFL group was significantly lower [ (4.89 ± 1.81 ) ug/L vs.( 12.97 ± 3.15 ) ug/L,P =0.000 ].After nutritional intervention and aerobic exercises,BMI [ ( 26.65 ± 2.39 ) kg,/m2 vs.(29.84 ±3.16) kg/m2,P =0.000] 、FBG [ (5.61 ±0.47) mmol/L vs.(6.02 ±0.63) mmol/L,P =0.004 ],and FINS [ ( 11.12 ± 2.01 ) mU/L vs.( 13.73 ± 3.24) mU/L,P =0.000 ] in the NAFL group were decreased significantly,while serum adiponectin [ (6.54 ±2.12) ug/L vs.(4.89 ± 1.81 ) ug/L,P =0.001 ] was significantly higher than the level before intervention.Serum adiponectin was negatively correlated with BMI,FBG,FINS,HOMA-IR,and TG (P =0.004,0.000,0.000,0.000,and 0.010),and positively correlated with high density lipoprotein cholesterol (P =0.026),but not correlated with TC (P =0.101 ).ConclusionThe combination of nutritional intervention and aerobic exercises can improve the level of serum adiponectin,adjust the level of serum glucose and serum lipids,and alleviate insulin resistance in NAFL patients.

Objective To study the relationship between serum adiponection and liver function and insulin level in patients with hepatogenous diabetes.Methods The research subjects included:28 patients with hepatog-enous diabetes who were admitted at Liaocheng People's Hospital (hepatogenous diabetes group);27 patients with simple type 2 diabetes without any complication (simple type 2 diabetes group),and 27 normal controb (control group).Blood adiponectin,fasting blood glucose (FBG),fasting insulins (FINS),alanine aminotransferase (ALT),aspartate transferase (AST),total bilirubin (TBIL) and albumin (ALB) were measured,and according-ly the insulin sensitivity index (ISI) was calculated.Results Compared with the control group.serum adiponec-tin levels and ISI levels were significantly lower in the other two groups (P<0.01),and the adiponectin levels were significantly higher in hepatogenous diabetes group than in simple type 2 diabetes group (P<0.05).The FBG and FINS levels in the hepatogenous diabetes group and the FBG levels in the simple type 2 diabetes group were significantly higher than those in control group (P<0.01).The FINS levels were significantly higher in the hepatogenous diabetes group than in simple diabetes group (P<0.05),while the levels of FBG and ISI were lower than that of simple type 2 diabetes group (P<0.05).Adiponectin levels were negatively correlated with ISI (r= 0.5265,P=0.000),and positively correlated with FBG (r=-0.6040,P=0.000),and were not correlated with liver functions Conclusion Insulin resistance and abnormal metabolism of adipenection exist in patients with hepatogenous diabetes and may together affect the occurrence and development of hepatogenous diabetes.

Objective:To observe the effect of nutritional intervention in patients with hepatic diabetes.Methods:57 patients were enrolled and randomly divided into treatment group(n=29) and control group(n=28).On the base of same liver medicine,the control group received insulin therapy while the treatment group received strict nutrition intervention.Results:The level of fasting blood glucose and blood glucose 2 hours after meal and glycosylated hemoglobin were decreased significantly in treatment group(P

Objective To study the expression of RUNX3 mRNA in primary liver cancer (PHC) tissue and its surrounding normal tissue,and its clinical significance.MethodsReverse transcription polymerase chain reaction (RT-PCR) was performed to detect the expression of RUNX3 mRNA in tumor and peritumor tissues in 51 patients with PHC.The relationship between RUNX3 mRNA expression and some clinical pathological parameters was analyzed.ResultsThe relative expression values of RUNX3 mRNA in the tumor tissue and the surrounding normal tissue were 0.4509±0.0963 and 0.9147± 0.0222,respectively.The difference was significant (t=33.6087,P＜0.001).The RUNX3 mRNA expression in tumor tissue correlated with some clinical pathological parameters including low tumor differentiation,positive cancer embolus and intrahepatic invasion and metastasis.The RUNX3 mRNA expression was not correlated with other clinicopathological parameters including gender,cancer diameter,cancer location,hemorrhage and necrosis of cancer,and histotype.ConclusionRUNX3 may be a new tumor suppressor gene for PHC.

OBJECTIVE:To establish a turbidimetric method for the determination of the potency of the crude drugs and tablets of oxytetracycline. METHODS: By turbidimetric method in which Staphylococcus aureus was used as the test organism with biomass concentration of 1.0%～1.5% (V/V). The culture temperature was 37 ℃ and the culture time was about 4 h. The method was compared with the cup-plate method in potency. RESULTS: The linear range of oxytetracycline was 0.05～0.4 IU?mL-1. The average recovery of the crude drug of oxytetracycline was 99.59% (RSD=2.0%) and that of oxytetracycline tablets was 99.51% (RSD=1.91%), showing no significant difference as compared with the cup-plate method in contents. CONCLUSIONS: The method was sensitive and rapid yet with few influencing factors thus applicable for the determination of the potencies of oxytetracycline and its tablets.
