Objective To investigate the inhibition effects of different antihistamines on the expressions of chemokines and cytokines released by nasal polyps in vitro.Methods The fresh nasal polyps resected under endoscope from the patients admitted to our hospital were cultured with mizolastine,cetirizine,loratadine,fexofenadine,dexamethasone,or ciclosporin A respectively for 24 h,with the addition of histamine and arachidonic acid.The total RNA of polyps was obtained and purified with tripure isolation reagent.The mRNA expression levels of monocyte chemoattractant protein-1(MCP-1),monocyte chemoattractant protein-3(MCP-3),regulated on activation,normal T cell expressed and secreted(RANTES),eotaxin were analyzed by RT-PCR.The concentrations of interleukin(IL)-4,IL-5 and tumor necrosis factor-?(TNF-?)in cultured supernatant was detected by ELISA.Results The MCP-1 mRNA expression in nasal polyps treated by mizolastine was weaker than those by loratadine and fexofenadine;the MCP-3 mRNA expression by mizolastine was weaker than those by cetirizine and loratadine;the RANTES mRNA expression by mizolastine was weaker than those by loratadine and fexofenadine;the eotaxin mRNA expression by mizolastine was weaker than that by cetirizine(all P

Objective To investigate the value of N-termind pro-B-type natriuretic peptide(NT-pro-BNP)in differential diagnosis of dyspnea in emergency department, and to investigate the rapid diagnosis cutoff of dyspnea due to acute congestive heart failure. Methods Ninety. one cases of dyspnea in emergency department recruited from January to June ,2008 were divided into two groups: acute cardiac dyspnea group and none acute cardiac dyspnea group. To evaluate the value of different parameters in differential diagnosis of dyspnea in emergency department and analysis the area under the receiver-operating characteristic of different parameters for the diagnosis of acute cardiac dyspnea. To achieve the best cutoff of different parameters for the diagnosis of dyspnea due to acute congestive heart failure finally. Results Among two groups, NT-pro-BNP (acute cardiac dyspnea vs. none acute cardiac dyspnea,6203.50 ng/L vs. 1410.00 ng/L,P ＜ 0.01), Troponin Ⅰ (acute cardiac dyspnea vs. none acute cardiac dyspnea,0.12 μg/L vs. 0.03 μg/L,P ＜0.01) ,left ventricular ejection fraction(acute cardiac dyspnea vs. none acute cardiac dyspnea,46.25% vs. 65.60%, P ＜ 0.01), left atrial diameter (acute cardiac dyspnea vs. none acute cardiac dyspnea,42.75 mm vs. 36.00 mm,P ＜0.01) had significant difference. NT-pro-BNP at cutoff of ≥3715 ng/L was highly sensitive and specific for the diagnosis of acute cardiac dyspnea. Receiver-operating characteristic analyses demonstrated that NT-pro-BNP and left ventricular ejection fraction was the best diagnostic indices of acute cardiac dyspnea. The area under the receiver-operating characteristic curve of Nt-pro-BNP was 0.828 ± 0.045 (P ＜ 0.01),and left ventricular ejection fraction was 0.829 ± 0.049 (P ＜ 0.01). Correlation analysis showed that NT-pro-BNP was correlated with left ventricular ejection fraction (P ＜ 0.01). The combined test of NT-pro-BNP and left ventricular ejection fraction was performed. Specificity increased to 96.50%, total consistent rate increased to 83.50% ,positive predictive value increased to 91.30%, positive likelihood ratio 17.60, faulse diagnostic rate decreased to 3.50%. Conclusions NT-pro-BNP examination in emergency department was helpful to rapid differential diagnosis of dyspnea. It helped to differentiate the patients with acute congestive heart failure and none acute congestive heart failure causes of dyspnea.

Objective To evaluate the clinical efficacy of acupuncture plus auricular point electroacupuncture and its effect on the quality of life (QOL).Method Ninety-eight patients with post-stroke depression were randomized into a treatment group and a control group, 49 cases in each group. The treatment group was intervened by acupuncture plus auricular point electroacupuncture, while the control group was by oral administration of Fluoxetine hydrochloride. The Hamilton Depression Scale (HAMD), Side-effect Rating Scale (SERS), and the World Health Organization Quality of Life Questionnaire-Brief Version (WHOQOL-BREF) were observed before and after intervention, and the clinical efficacies were also compared.Result The total effective rate was 89.1% in the treatment group versus 87.0% in the control group, and the between-group difference was statistically insignificant (P>0.05). Respectively after 2-week, 4-week, and 8-week treatment, the HAMD scores were significantly different from that before intervention in the treatment group (P<0.05). Respectively after 2-week, 4-week, and 8-week treatment, the HAMD scores were significantly different from that before intervention in the control group (P<0.05). There were no significant differences in comparing the HAMD scores between the two groups after 2-week, 4-week, and 8-week treatment (P>0.05). The SERS scores in the treatment group were significantly different from that in the control group after 4-week and 8-week treatment (P<0.05). In the treatment group, the SERS score after 8-week treatment was significantly different from that after 4-week treatment (P<0.05). After treatment, the scores of general health domain 1 and 4, physical health domain, psychological health domain, and environment domain from WHOQOL-BREF were significantly changed in both groups (P<0.05). After intervention, the physical health domain score of the treatment group was significantly different from that of the control group (P<0.05).Conclusion Acupuncture plus auricular point electroacupuncture is an effective approach in treating post-stroke depression, and it can improve the quality of life of the patients.

The faults of large-scale equipments of hospitals, such as imaging equipment, laboratory equipment, sterilizing equipment and bioelectric equipment, result in considerable expenses of hospitals. Usual and special preventive maintenances (PM) should be performed to decrease the expenses. Additionally, PM can be carried out when the condition is possible.
