Objective To explore the relationship between levels of plasma homocysteine (Hcy) and adrenomedullin (ADM) and sudden sensorineural hearing loss (SSHL) in elderly patients. Methods The 80 patients with SSHL but without any treatment were selected as SSHL group, while 80 age-and sex-matched subjects without SSHL were collected as the control group. The levels of plasma Hcy and ADM were measured by fluorescence method and radioimmunoassay, respectively. And the levels of plasma Hey, ADM, total cholesterol (TC) and triglyceride (TG) were compared between the two groups. Results The levels of plasma Hcy, ADM, TC and TG were significantly higher in SSHL group than in control group [(13. 81±2.88) μmol/L vs. (11. 58±2. 80)/xmol/L, (26. 40±3. 20)ng/L vs. (22. 45±2. 80)ng/L, (5.22±0. 87)mmol/L vs. (4. 52±0. 81)mmol/L, (1.80 ±0. 12)mmol/L vs. (1.52±0. 13)mmol/L;t=5. 03, 8. 22, 7.48, 3. 85, all P<0. 01). When the two groups with hypertension were compared, the levels of plasma Hey, ADM, TC and TG were (15.30±2. 77)μmol/L, (29.40±2. 80) ng/L, (5. 48±0. 98) mmol/L and (1.92±0. 18) mmol/L in SSHL group, which were higher than those in control group[(12. 80±2. 62) μmol/L, (25.20± 2. 60) ng/L, (5.01±1.03) retool/L, (1.62±0. 15) mmol/L3 (t=4.03, 7.01, 3.25, 7. 80, all P< 0. 01). There were no differences in systolic and diastolic blood pressure between the two groups(t= 0. 87, 0. 64;P=0. 38, 0. 55).Conclusions The changes of plasma levels of Hey and ADM in the elderly suggest that they could involve in the pathogenic process of SSHL, which may provide referential value for understanding the state of the disease and judging the prognosis

Objective To evaluate clinical safety and efficacy of autologous tissue antigens loaded dendritic cells (DC)in the treatment of elderly patients with gastric cancer.Methods Fresh tumor cells were isolated from surgical specimens in twenty patients with gastric cancer. Single cell suspensions were obtained and induced to apoptosis by heat shock. The apoptotic tumor cells were frozen before use.Peripheral blood mononuclear cells were isolated and cultured with recombinant human granulocyte macrophage-colony stimulating factor (GM-CSF) and interleukin-4 (IL-4).DCs were loaded with apoptotic tumor cells. The immunological and clinical responses were examined after the final vaccination. ResultsVaccination of dendritic cells was well tolerated and no toxicity was observed. The cytokine levels in serum such as IL-2(46 pg/mg vs 89 pg/mg), IL-12(44 pg/mg vs. 86 pg/mg) and IFN-γ(38 pg/mg vs.82 pg/mg) were increased after vaccinations as compared with pretherapy. DTH test were positive in five patients (5/10). The antigen special cells for CD8+/ IFN-γ+ were increased in five patients(5/10). The size of retroperitoneal lymph node of one patient was reduced. The tumor marker CEA level were decreased in five patients, stable in eight patient and increased in two patients.Conclusions Autologous DC vaccines loaded with autologous tumor antigens could improve function of non specific immunity and elicit specific T cells immunologic response and is one of safe and effective treatments for gastric cancer.

Poly(ADP-ribose) polymerase-1 (PARP-1) has emerged as a promising anticancer drug target due to its key role in the DNA repair process. It can polymerize ADP-ribose units on its substrate proteins which are involved in the regulation of DNA repair. In this work, a novel series of para-substituted 1-benzyl-quinazoline-2, 4 (1H, 3H)-diones was designed and synthesized, and the inhibitory activities against PARP-1 of compounds 7a-7e, 8a-8f, 9a-9c and 10a-10c were evaluated. Of all the tested compounds, nine compounds displayed inhibitory activities with IC50 values ranging from 4.6 to 39.2 micromol x L(-1). In order to predict the binding modes of the potent molecules, molecular docking was performed using CDOCKER algorithm, and that will facilitate to further develop more potent PARP-1 inhibitors with a quinazolinedione scaffold.

PARP [poly(ADP-ribose)polymerase] represents a novel potential target in cancer therapy. It is involved in a DNA repair process by catalyzing the transfer of ADP-ribose units from NAD to a number of its substrate proteins. In this work, a series of novel azaindole derivatives was designed and synthesized. Moreover, 16 target molecules were screened and 8 compounds displayed inhibitory activity against PARP-1. It has been demonstrated that these azaindoles bearing cycloamine substituents at 2-position were active to both PARP-1 and PARP-2.
