Podcast,a versatile web-based technology,has been widely employed in international nursing education.In China,however,it is only applied based on its video-related function.The other functions,such as subscribing,participating,mobile,and sharing learning option have not been fully exploited.The studies on application of podcast demonstrate that it can excite the learning interest,alleviate stress and anxiety,and enhance the preclinical educational experience.Moreover,it facilitates the self-study ability.Therefore the podcast is expected to be applied more widely in the domestic nursing education.

Objective To investigate the expression changes of Toll-like receptors(TLR) and the signaling pathway function on airway epithelial cells infected with human metapneumovirus(hMPV), and to explore the mechanisms of hMPV-induced airway inflammation. Methods A549 cells were infected with hMPV live or co-cultured with UV-inactivated hMPV in vitro. Growth curve of the virus in A549 cells was established and mRNA expression of TLR were detected by RT-PCR assay and real-time PCR assay at 3, 6, 9, 12, 24 h post infection. IFN-α and TNF-α in the culture supernatants were detected by ELISA. Results hMPV was able to replicate in A549 cell, growing to peak titer of 10~(5.2) TCID_(50)/ml at 3 d after infection. Most of TLR mRNA levels were up-regulated by hMPV infection but not UV-inactivated viruses via RT-PCR assay (P<0.05) after 6 h of stimulation. Real-time PCR assay showed that TLR3-4, TLR7-9 mRNA increased after being infected by hMPV in a time-dependent manner. The expression of IFN-α and TNF-α in the cul-ture supernatants were significantly up-regulated after 24 h infected by hMPV. Conclusion hMPV infection up-regulates the expression of TLR in lung epithelial cells. The inflammatory response to hMPV may associ-ate with part of TLR signal transduction pathway.

Objective To explore the association between the daily intake of alcohol and blood pressure in Chinese.Methods With the baseline data of the Qingdao Port Health Study,all subjects aged 18 to 54 yrs including all in-service and retired employees in Qingdao port were selected and divided into seven groups according to their daily intake of alcohol: groups of 0,0～,5～,10～,20～,40～ and 60～g alcohol/d,also stratified by ages.The amount of alcohol intake was assessed by a questionnaire.The cross-sectional association between blood pressure and intakes of alcohol was analyzed with general linear model and Logistic regression.Results In the groups of 25～34,35～44,45～54 yrs old both before and after adjustment,systolic and diastolic blood pressure were linearly increased with the amount of alcohol intake from the 0 g/d group to 60～g/d group.In the group of 18～24 yrs old,there was no obvious relationship between BP and alcohol intake.Logistic regression model showed that odds ratios in the groups of 0～g/d,5～g/d,10～g/d,20～g/d,40～g/d and 60～g/d versus the abstainers was 1.05,1.14,1.08,1.24,1.30 and 2.02,respectively,and the prevalence of hypertension in the 20～g/d group was significantly higher than that in the 0 g/d group and groups of low or moderate alcohol intake.Conclusion An increasing and linear relationship between alcohol consumption and blood pressure was established,and alcohol intake ≥20 g /d is an independent risk factor for hypertension.

Six DNA extraction methods and four DNA purification methods were compared and analyzed in this study to get higher quality DNA from the rhizospheric soil of Fritillaria thunbergii Miq.Results showed that higher purity DNA were harvested by pretreating the soil with 20 mmol/L EDTA(pH 7.5),then isolating soil DNA with CTAB-SDS-frozen-thawing,and further purified by agarose method.The recovery rate of this soil DNA was about 44.00 ?g/g ? 2.65 ?g/g soil,and they were qualified for the microbial diversity analysis in the rhizospheric soil of F.thunbergii Miq based on the 16S rDNA sequence.

ObjectiveTo investigate the effect of Du meridian electroacupuncture of the scalp on deglutition disorder after stroke.Methods67 patients with deglutition disorder after stroke were randomly divided into the experimental group (n=34) and control group (n=33). The patients of the experimental group were received Du meridian electroacupuncture of the scalp as main therapy, combined with routine medicine treatments; the patients of the control group were only received routine medicine treatments. Before and after treatments, deglutition function of all patients was assessed by drinking water test and clinical effect was also assessed.ResultsAfter treatment, the deglutition function of the patients in the experiment group was markedly improved and superior to those in the control group ( P<0.01).ConclusionDu meridian electroacupuncture can markedly improve the clinical effect of routine medicine treatments on deglutition disorder after stroke.

Objective To explore the effect and mechanism of stent implantation on the quality of sexual activity in middle and old age male patients with exertional angina pectoris.Methods One hundred and seventy-two male patients with exertional angina pectoris were enrolled in this study,and they were divided into control group (94 patients) and percutaneous coronary intervention group (78 patients).The patients in control group were given routine pharmacotherapy and the patients in percutaneous coronary intervention group were given drug-eluting stent implantation and routine pharmacotherapy.The sexual activity function was evaluated by international index of erectile function (IIEF)-5 scale before treatment and 3 months after treatment.The times of sexual intercourse was added up.The evaluation of angina pectoris was performed by the grade of Canadian cardiovascular society (CCS).At the same time,the walking distance and heart rate were measured through 6-minute walking test.The left ventricular ejection fraction(LVEF) was detected by echocardiogram.Results After treatment for 3 months,the scores of IIEF-5,the degree of sexual satisfaction,the times of sexual intercourse and the grade of CCS in percutaneous coronary intervention group were significantly improved compared with those in control group [(20.58 ± 7.36) scores vs.(16.38 ± 6.35) scores,(4.32 ± 1.38) scores vs.(2.51 ± 1.89) scores,(6.3 ± 3.2) times/month vs.(3.5 ± 1.6) times/month,(1.10 ± 0.43) grades vs.(2.50 ± 1.1 0) grades] (P ＜ 0.05).The walking distance and heart rate after 6-minute walking test and LVEF in percutaneous coronary intervention group were significant improved compared with those in control group [(386 ± 82) m vs.(281 ± 86) m,(95 ± 18) times/minute vs.(122 ± 25) times/minute,(65.2 ± 11.2)％ vs.(55.6 ± 13.8)％] (P ＜ 0.05).Conclusions Stent implantation can significandy improve the quality of sexual activity in middle and old age male patients with exertional angina pectoris.The mechanisms are associated with the exercise capacity increasing and the frequency of angina pectoris attacks decreasing during sexual intercourse.

Objective To investigate the influence of proton pump inhibitors (lansoprazole and rabeprazole) on dual-antiplatelet therapy (DAPT) in patients with coronary heart disease.Methods One hundred and eighty-one cases of coronary heart disease with DAPT were selected,and they were divided into control group (66 cases,no proton pump inhibitors administered),lansoprazole group (65 cases,lansoprazole administered) and rabeprazole group (50 cases,rabeprazole administered).100 mg/day of aspirin and 75 mg/day of clopidogrel were concomitantly used in all patients.Platelet aggregation rate,platelet aggregation threshold index (PATI) and adenosine diphosphate (ADP) was measured.Results The ADP-PATI in control group was (3.47 ± 0.96) μ mol/L,lansoprazole group was (3.28 ± 1.05) μ mol/L,rabeprazole group was (3.32 ±0.83) μ mol/L,and there was no statistically significant difference among three groups (P＞0.05).There was also no statistically significant difference in platelet aggregation rate and collagen-PATI among three groups (P ＞ 0.05).Conclusion In patients with coronary artery disease,the concomitant use of lansoprazole or rabeprazole does not affect antiplatelet action during DAPT.

Serum 25-(OH)D3concentration was determined in subjects with different types of obesity. The serum 25-(OH)D3levels in overweight or obese and central obese subjects were lower than that in non-obese subjects.(P＜0.01). In a multiple linear regression analysis serum 25-(OH)D3was independently and negatively correlated with body mass index and waist circumference.
