Objective To study the effect of simvastatin(SV) on NF-kappa B p65 expression in liver of insulin resistant rats. Methods Male Wistar rats were divided into two groups:basic chow(NC,n=15)or high-fat diet(HF,n=20)for 10 weeks feeding, then assessed by euglycemic-hyperinsulinemia clamp technique. Rats in HF group were treated with(HFS,n=5)and without (HFN,n=5) SV 10mgkg-1d-1 in gavage for 5 weeks.NF-kappa B p65 expressions were tested with Western blot. Results The glucose infusion rate (GIR) in HF group decreased significantly compared with NC group (P

Objective To investigate the difference of serum high sensitivity C-reactive protein(hs-CRP)concentrations in subjects with various glucose tolerances,and to analyze the correlation with insulin resistance.Methods A total of 90 subjects,who came from the Medical Examination Center of the First Hospital Affiliated to China Medical University from Oct.2004 to Apr.2005,were divided into five groups according to oral glucose tolerance test(OGTT):normal glucose tolerance(NGT)group;impaired fasting glucose(IFG)group;impaired glucose tolerance(IGT)group;IFG and IGT(IGT/IFG)group;newly diagnosed,complication-free type 2 diabetes(T2DM)group.By using the ELISA methods,the concentration of serum high sensitivity C-reactive protein(hs-CRP)was measured in these subjects,and its correlation with homeostasis model assessment insulin resistance index(HOMA-IR)was andlysed.Results The concentration of hs-CRP was significantly higher in IFG,IFG/IGT,T2DM than in NGT.The concentration of hs-CRP was positively correlated with glucose metabolism index and insulin resistance index.Conclusion Our study demonstrates that inflammation already exists not only in T2DM patients but also in subjects with IFG.Inflammation might participate in the occurance and development of T2DM.

Objective To observe the effect of tetraethylplyrazine(TMP) on outward K~+ channel of outer hair cells in guinea pig cochlea.Methods 60 guinea pigs were divided into 6 groups randomly in the experiment.Auditory brainstem response was used to monitor the change of ABR thresholds and patch clamp techniques to observe the effect of TMP on outward K~+ channel.Results TMP decreased the elevated ABR threshold caused by streptomycin. The TMP increased the amplitudes of calcium sensitive potassium channels (I_ K(Ca) ) and delayed outward potassium channels (IK) of outer hair cells of guinea pig cochlea.Conclusion The study indicates that TMP may act as a protective agent against ototoxicity of streptomycin. The amplitudes of I_ K(Ca) and IK of outer hair cells are increased by the TMP,suggesting the possible mechanisms of reducing ototoxicity.

Objective To study the association of the serum soluble intercellular adhesion molecule-1(SICAM-1) and soluble vascular cell adhesion molecule-1(SVCAM-1) with metabolic syndrome(MS) and its components. Methods The MS was defined by criteria of the international diabetes federation. The levels of SICAM-1 ,SVCAM-1,plasma glucose,insulin,lipids,uric acid, glycosylated haemoglobin A(1C), and blood viscosity were measured. Results The concentrations of SICAM-1 and SVCAM-1 were significantly higher in subjects with MS and its components than in those without them. The concentrations of SICAM-1 and SVCAM-1 were correlated positively with disorder number of BMI, WHR, SBP, DBP,FPG, 2 hour plasma glucose, triglyceride, uric acid, HbA1c, blood viscosity and HOMA-IR,and negatively with high density lipoprotein cholesterol. Conclusions The concentrations of SICAM-1 and SVCAM-1 rise with the increase of the number of MS components. Endothelial dysfunction might participate in the occurrence and development of MS.

Background The mitochondrial Na+/Ca2+exchanger, NCLX, plays an important role in the balance between Ca2+influx and efflux across the mitochondrial inner membrane in endothelial cells. Mitochondrial metabolism is likely to be affected by the activity of NCLX because Ca2+activates several enzymes of the Krebs cycle. It is currently believed that mitochondria are not only centers of energy produc-tion but are also important sites of reactive oxygen species (ROS) generation and nucleotide-binding oligomerization domain receptor 3 (NLRP3) inflammasome activation. Methods&Results This study focused on NCLX function, in rat aortic endothelial cells (RAECs), induced by glucose. First, we detected an increase in NCLX expression in the endothelia of rats with diabetes mellitus, which was induced by an injection of streptozotocin. Next, colocalization of NCLX expression and mitochondria was detected using confocal analysis. Suppression of NCLX expression, using an siRNA construct (siNCLX), enhanced mitochondrial Ca2+influx and blocked efflux induced by glucose. Un-expectedly, silencing of NCLX expression induced increased ROS generation and NLRP3 inflammasome activation. Conclusions These findings suggest that NCLX affects glucose-dependent mitochondrial Ca2+signaling, thereby regulating ROS generation and NLRP3 in-flammasome activation in high glucose conditions. In the early stages of high glucose stimulation, NCLX expression increases to compensate in order to self-protect mitochondrial maintenance, stability, and function in endothelial cells.

BACKGROUND: Twin-block appliance has been confirmed to efficiently change hard tissue and the profile of soft tissue.Whether a linear relationship exists between soft tissue and hard tissue changes remains unclear.OBJECTIVE: To evaluate the face convexity changes of soft and hard tissues after Twin-block appliance therapy and compare with controls.METHODS: Thirty-one class Ⅱ division 1 malocclusion subjects with hand-wrist radiographs in FG-G stage were selected.Among the 31 patients,17 received Twin-block appliance therapy,serving as experimental group,and the remaining 14 subjects abandoned treatment,serving as control group.Cephalometric radiographs of each included subject were taken prior to and after treatment or observation.Face convexity of soft and hard tissues,as well as the face convexity changes,was compared between the experimental and control groups.Linear regression equation was employed to analyze the linear association between soft-and hard-tissue changes.Regression equations of experimental and control groups were compared.RESULTS AND CONCLUSION: Prior to and after Twin-block appliance therapy,a significant correlation existed between the position changes of superior and inferior alveolar sockets relative to the nose and mandible,and the position changes of upper and lower lip pits relative to the nose and mandible,i.e.,there was a linear correlation between A-E change and Ss-E change,and between B-E change and Si-E change.The largest Pearson's correlation coefficient(0.839)appeared between Si-E change and B-E change,indicating the best correlativity between these two changes.Statistical analysis revealed that the linear equations of face convexity changes of soft and hard tissues after Twin-block appliance therapy were Si-E=0.745 B-E,Ss-E=0.276 A-E.These linear equations would be helpful to explain mandible growth and face convexity change after Twin-block appliance therapy and predict the prognosis of face convexity change.
