Objective To observe the changes of renal function in elderly patients with heart failure but normal ejection fraction,and explore its clinical significance. Methods A total of 145 cases diagnosed as coronary artery disease from Department of Geriatric Cardiology in The First Affili?ated Hospital of China Medical University were enrolled in the study. All of the cases were divided into HFPEF group(65 cases)and non HFPEF group(80 cases). All patients underwent cardiac ultrasound,BNP and renal function examination,and the glomerular filtration rate(GFR)was cal?culated. Results The average age of patients in HFPEF group was significantly higher than non HFPEF group(P<0.001),and the incidence of hypertension,diabetes,coronary heart disease,atrial fibrillation,or concomitant incidence of two or more kinds of these disease in HFPEF group was significantly higher than non HFPEF group(P1=0.046,P2<0.001,P3=0.002,P4=0.021,P5<0.001);the GFR of two groups of patients were lower than normal level,but the GFR of HFPEF group was significantly lower than non HFPEF group(P=0.046);E/Em was significantly higher (P<0.001),Em was significantly lower(P=0.002),left atrial diameter was significantly higher(P<0.001),LVEF was significantly lower(P=0.012),BNP values were significantly higher(P=0.001)in HFPEF group than in the non?HFPEF group;There were significant linear correlation between GFR and E/Em(r=-0.428,P=0.001),GFR and the BNP(r=-0.435,P=0.001),E/Em and BNP(r=0.392,P=0.002)in HFPEF group. Conclusion Elderly patients with heart failure but normal ejection fraction were older,and more of them were complicated with hyperten?sion,diabetes,coronary heart disease,atrial fibrillation,or concurrency of these diseases. Glomerular filtration rate was significantly decreased in el?derly patients with HFPEF,which has a significant correlation with diastolic function parameters.

OBJECTIVETo investigate the effect of Actinidia chinensis Planch polysaccharide (ACPS) on the growth and apoptosis of human gastric cancer SGC-7901 cells, and to explore the effect of SGC-7901 cells on p-p38 expression.

METHODSThe inhibition rates at different concentrations of ACPS on SGC-7901 cells at 24, 48, and 72 h were detected using CCK-8 method. Apoptosis ratios in SGC-7901 were determined by flow cytometry after 48-h treatment of different concentrations of ACPS. The expression of pro-caspase-9, PARP, and p-p38 in SGC-7901 cells after treated by different concentrations of ACPS was detected using Western blot. The expression of pro-caspase-9, PARP, and p-p38 was detected after SGC-7901 cells were pre-treated by p38 specific inhibitor.

RESULTSCompared with the control group, the optical density of SGC-7901 cells decreased after treated by 1, 2.5, 5, and 10 mg/mL ACPS (P < 0.05). Meanwhile, the longer the acting time, the lower the optic density (P < 0.01). IC50 was 7.43 mg/mL at 24 h; 3.88 mg/mL at 48 h, and 1.32 mg/mL at 72 h respectively. ACPS suppressed the protein expression of pro-caspase-9 (P < 0.01) and up-regulated the expression of PARP (89KD) (both P < 0.01). Further study showed that the protein expression of p-p38 was up-regulated in SGC-7901 cells treated by ACPS of different concentrations at 24 h (P < 0.05). The expression of phosphorylation p38 and the ACPS induced apoptosis of SGC-7901 cells could be inhibited after treated by specific inhibitor for 2 h.

CONCLUSIONSACPS could inhibit the growth of SGC-7901 cells and induce apoptosis. The underlying mechanism of inducing apoptosis was partially due to activating the p38MAPK path and further activating Caspase9 and PARP, finally leading to cell death.

A study was made on the pharmacokinetic regularity of effective components salvianolic acid B and ferulic acid in Salviae Miltiorrhizae Radix et Rhizoma (SMRR) and Chuanxiong Rhizoma(CR) in rats, so as to discuss the compatibility mechanism of Salviae Miltiorrhizae Radix et Rhizoma and Chuanxiong Rhizoma. Rats were randomly divided into three groups and intravenously injected with 50 mg x kg(-1) salvianolic acid B for the single SMRR extracts group, 0.5 mg x kg(-1) ferulic acid for the single CR extracts group and 50 mg x kg(-1) salvianolic acid B + 0.5 mg x kg(-1) ferulic acid for the SMRR and CR combination group. The blood samples were collected at different time points and purified by liquid-liquid extraction with ethyl acetate. With chloramphenicol as internal standard (IS), UPLC was adopted to determine concentrations of salvianolic acid B and ferulic acid. The pharmacokinetic parameters of salvianolic acid B and ferulic acid were calculated with WinNonlin 6.2 software and analyzed by SPSS 19.0 statistical software. The UPLC analysis method was adopted to determine salvianolic acid B and ferulic acid in rat plasma, including linear equation, stability, repeatability, precision and recovery. The established sample processing and analysis methods were stable and reliable, with significant differences in major pharmacokinetic parameters, e.g., area under the curve (AUC), mean residence time (MRT) and terminal half-life (t(1/2)). According to the experimental results, the combined application of SMRR and CR can significantly impact the pharmacokinetic process of their effective components in rats and promote the wide distribution, shorten the action time and prolong the in vivo action time of salvianolic acid B and increase the blood drug concentration and accelerate the clearance of ferulic acid in vivo.

Objective To evaluate the association between interleukin-I(IL-1)loci polymorphisms and increased risk of gastric carcinoma in samples from northern Chinese population.Methods Blood sam- ples from 126 patients with gastric cancer and 125 controls with chronic gastritis were collected.Genomic DNA was extracted and polymorphisms at -31(C to T),-511(C to T)and at intron 2(86-bp VNTR)of IL-I RN were genotyped by PCR-CTPP,PCR-RFLP and PCR.For detection of Hp infection fast urenase test,~(14)C breath test and serum anti-Hp IgG antibody assay were used.Results Five kinds of polymorphism of IL-IRN were found as 1/1,1/3,1/4,1/2 and 2/2,and the frequencies in patients were 76.19%、4.76%、6.35%、11.90% and 0.79%,respectively.However,the frequencies in controls were 76.00%、4.00%、4.80%、13.60% and 1.60%.No significant differences were observed between cases and controls in each genotype.The polymorphism of IL-IB-31 allele was C/C,C/T and T/T.The frequencies in patients were 12.70% ,47.62% and 39.68%,and in controls 28.00%,48.80% and 23.20% respectively.IL-1B- 31 T/T carriers were at an increase risk of gastric cancer with an odds ratio of 3.772(95% CI,1.786- 7.966).IL-IB-511 alleles were C/C,C/T and T/T.The frequencies in patients were 19.20%,56.80% and 24.00% and in controls,23.38%,49.19% and 27.42% respectively.No significant differences were observed between cases and controls in each genotype.Conclusion In Chinese population,the polymor- phism of IL-1B-31 alleles may be associated with the susceptibility of gastric cancer.However,no evidence was found to support that the polymorphisms of IL-1RN and IL-I B-511 alleles had relationship with gastric cancer.

AIM: To investigate the role of N-cadherin in the delamination of neural crest cells. METHODS: The normal expression of N-cadherin in neural tube was identified using in situ hybridization. The cells with N-cadherin over expression were obtained by transfection of wild-type N-cadherin (wt-N-cadherin) ,and the cells with N-cadherin silencing expression were obtained by transfection of dominant-negative N-cadherin (dn-N-cadherin). The migration of cranial neural crest cells was determined by the technique of immunohistochemistry. RESULTS: Either overexpression or down-regulation of N-cadherin significantly affected the migration of cranial neural crest cells. CONCLUSION: Delamination and migration of the cranial neural crest cells rely on the relative N-cadherin expression in the neural tube during neurulation.
