AIM: To investigate the effects of fenofibrate on angiotensin Ⅱ ( AngⅡ)-induced cardiomyocyte hypertrophy .METHODS:Primary neonatal cardiomyocytes were pretreated with fenofibrate (10μmol/L) for 1 h followed by stimulation with AngⅡ(100 nmol/L).The mRNA levels of ANF, BNP andβ-MHC were measured by real-time PCR. Western blotting was employed to determine the nuclear translocations of NFATc 4 and p65-NFκB.Co-immunoprecipitation was used to investigate the interaction of NFATc 4 with p65-NFκB in the nucleus of cardiomyocytes .In addition, the DNA binding activity of NFATc4 on the BNP promoter was determined by EMSA .RESULTS:Fenofibrate significantly inhibited AngⅡ-induced cardiomyocyte hypertrophy .Fenofibrate treatment inhibited the nuclear translocations of NFATc 4 and p65-NFκB, as well as the interactions of NFATc 4 with p65-NFκB in the nucleus of cardiomyocytes induced by AngⅡ.Fenofi-brate inhibited the binding activity of NFATc 4 with the BNP promoter , which was strengthened by AngⅡ.CONCLU-SION:Fenofibrate enhances the interaction of NFATc 4 with PPARα, decreases the interaction of NFATc 4 with p65-NFκB in the nucleus of cardiomyocytes , and inhibits the DNA binding activity of NFATc 4 induced by AngⅡ, which may be the important mechanisms of fenofibrate on inhibiting cardiac hypertrophy .

It showed that cinnamaldehyde induced apoptosis through the downregulation of Bcl-2 , Bcl-xL and Survivin expression , upregulation of Bax and Bak expression , downregulation of Bcl-2 and Procaspase-3 , and upregulation of BAX . It was concluded that cinnamaldehyde had inhibitory effect on the proliferation of human gastric carcinoma cell line BGC-823 and induced apoptosis . It may be related to the activation of the endogenous apoptosis pathway .

Objective To explore the possible role of vitamin D in the pathogenesis of IgA nephropathy (IgAN). Me-thods After the IgAN model was successfully induced at 12 weeks, the BALB/C mice were randomly divided into IgAN group (n=15) and IgAN+VitD group (n=15). The nephrosis mice were administrated with 100 μl/d propylene glycol or propyl-ene glycol+1,25(OH)2D, 3 ng/(100g?d), for 6 weeks. The control group was setted (n=15). The level of 24 hour urine protein was determined at week 0, 12 and 18. At week 18, the levels of serum 25(OH)D, ifbroblast growth factor 23 (FGF23) and galactose-deifcient IgA1 (Gd-IgA1) were detected. The mRNA and protein expressions of interleukin-21 (IL-21) in Peyer’s patches (PPs) were detected by lfuorescent quantitative reverse transcription-polymerase chain reaction and western blot respectively. The protein expression of Bcl-6 was detected by western blot. The percentages of Tfh cells/T lymphocytes, B220+IgM+/B lympho-cytes, B220+IgA+/B lymphocytes, B220-IgA+/B lymphocytes in PPs were determined by lfow cytometry. Results Compared with control group, the levels of 24 hour urine protein, FGF23 and Gd-IgA1 were increased, serum 25(OH)D was decreased, the mRNA and protein expressions of IL-21 and the protein level of Bcl-6 were increased, the percentages of Tfh cells/T lym-phocytes, B220+IgM+/B lymphocytes, B220+IgA+/B lymphocytes, B220-IgA+/B lymphocytes were elevated in IgAN group (P<0.05). These indicators were improved in IgAN+VitD group. Compared with the IgAN group, the differences were statisti-cally signiifcant (P<0.05), however compared with control group, some indicators showed no signiifcant differences (P>0.05). Conclusions 1,25(OH)2D may protect the microenvironment of PPs in IgAN through inhibiting the differentiation of Tfh cells and B cells and the generation of Gd-IgA1.

Objective To make a further recongnizing of the manifestations of diffuse axonal injury (DAI)on CT images for the early accurate clinical diagnosis.Methods The CT image data and its correlated clinic features of 56 cases with diffuse axonal injury(44 male,12 female)were analyzed retrospectively.In this series,43 cases were caused by traffic accident,13 by falling from high place.Results 1. 44 cases had haemorrhage lesions(less than 2 cm in diameter)in brain parenchyma which were at the corticomedullary junction,corpus callosum,brain stem,basal ganglia,internal capsule.2. 41 cases had subarachnoid and/or intraventricular hemorrhage 3. 9 cases had acute generalized brain swelling 4. 5 cases were associated with epidural hematoma and 16 with subdural hematoma.Conclusion CT manifestation of DAI have some featrues,and can provide reliable evidence for accurate clinic diagnosis of DAI.

Objective To investigate the relation between alkaline phosphatase (ALP) in gingival crevicular fluid(GCF) and prognosis. Methods We measured the alkaline phosphatase in gingival crevicular fluid among 56 cases of implant tooth which included 2 failed cases, 5 cases in bad oral hygiene and with gingivitis, compared with the normal group consisted of 10 healthy persons. Results The difference of ALP level between normal group and success implant group is not significant, but between normal group and success with gingivitis group is significant (P＜0.05).The ALP level of 2 failed cases are highest (because of few failed cases, no statistics was done).Conclusions The ALP level in GCF is supposed to be an important index in evaluating the result of the implant.

Objective: To investigate the prevalence of hyponatremia and the relationship between hyponatremia and prognosis of dilated cardiomyopathy (DCM) for in-hospital patients. Methods: A total of 515 consecutive in-hospital DCM patients treated in HF center of Fu Wai Hospifal from 2008-10 to 2013-10 were retrospectively studied. Hyponatremia was deifned as the serum level of sodium < 135 mmol/L at ifrst admission. The prevalence of hyponatremia and the relationship between hyponatremia and DCM prognosis were studied including the risk of in-hospital time and mortality, the rates of all cause death and HF worsening death after discharge. Surviving patients were followed-up by clinical or telephone visit until 2014-11 or until the death. Results: There were 134/515 (26.0%) patients suffered from hyponatremia at admission, the serum level of sodium was related to HF symptom duration, NYHA functional classiifcation, systolic blood pressure (SBP), left atrial diameter and total bilirubin level, allP<0.01. Compared with non-hyponatremia, the patients with hyponatremia presented longer in-hospital time(14.8±11.1) days vs (11.2±5.8) days and higher in-hospital mortality (18.7% vs 1.8%), bothP< 0.01. There were 483 survivors discharged and were followed-up for (30.7 ± 19.5) months, during that period, the rates of all cause death and HF worsening death were 26.5% and 21.9% respectively. The patients with hyponatremia had the higher rates of all cause death (47.7% vs 20.3%) and HF worsening death (44.0% vs 15.5%), bothP<0.01. Multiple Cox regression analysis showed that with adjusted HF history (> 6 months vs≤ months ), NYHA functional classiifcation (Ⅱ-Ⅳ), SBP (per 10 mmHg elevation), total bilirubin level (per 1 mg/dl change) and LVEDD (per 5 mm change), the hyponatremia at admission is still one of the important independent predictors for all cause death (HR=1.836, 95% CI (1.248-2.702),P<0.01 and HF worsening death HR=2.139, 95% CI (1.406-3.253),P<0.01 in DCM patients after discharge. Conclusion: Hyponatremia is a common electrolyte disorder for in-hospital DCM patients, it is related to longer in-hospital time and higher mortality; higher rates of all cause death and HF worsening death after discharge in DCM patients.
