Objective To explore oropharyngeal swallowing disorders with videofluoroscopic swallowing study (VFSS). Methods 16 patients with dysphagia accepted VFSS with 10 ml of thin barium meal (50% w/v), thick barium meal (270% w/v), biscuit coated with thick barium meal in single swallow. Their swallowing function was observed on the lateral and anterior/posterior planes, including: symmetry of pyriform sinuses, oral transit time, presence of pharyngeal delay, pharyngeal transit time, oral and pharyngeal residue, and presence of aspiration.Results 5 patients demonstrated oral swallowing disorder. 3 patients demonstrated pharyngeal swallowing disorders, that was pharyngeal delay which caused in aspiration after swallowing. 8 patients demonstrated oropharyngeal swallowing disorders, and 3 of them presented aspiration,2 patients were silent aspirators, 1 was aspiration before and 1 after swallowing. The aspiration time could not be judged from the videofluoroscopy in the other one. For 4 patients with aspiration, 3 were severe, with more than 25% of the bolus aspirated, and 1 aspirated less than 5%. Conclusion VFSS can be helpful to plan individual rehabilitation.

Objective To learn the current status of health literacy of residents in Wenling City, and to explore the relationship between health literacy and socioeconomic status. Methods A total of 3200 residents aged 15-69 years old from 6 townships were selected by stratified multi-stage random sampling method and probability proportionate to size sampling (PPS) method, and a questionnaire surveyed was conducted. Results Totally 3189 questionnaires were effective and the overall level of health literacy of residents was 19.79% (631/3189) . The percentages of residents who had the basic health knowledge and concept, healthy lifestyle and behavior, health related skills were 23.27%、 24.21% and 23.83%, respectively. About 55.47% of residents had the literacy of safety and first-aid, which was the highest, followed by 38.66% with scientific health belief, 32.77% with literacy for disease prevention, 26.12% with health information, 14.14% with primary medical care and 7.49% with the literacy for chronic disease prevention. Logistic regression model showed that the health literacy level with institutions class was 2.25 times of manual workers class, and the health literacy level of people have bachelor degree or above was 6.93 times less literate or illiterate, and the health literacy level of family income of 200 thousand Yuan and above was 7.70 times of 0~50 thousand Yuan. The health literacy were different among different socioeconomic status residents (P<0.01) . Conclusion There are obvious gaps in health literacy among different socioeconomic status groups. Health education should be strengthened among residents, especially among the manual workers class, low education class and low income class.

AIM: To observe the change of subunit of NADPH oxidation enzyme complex nox - 1 protein in cardiocyte hypoxia - reoxygenation injury and the role of cardiotrophin -1.METHODS: Cardiomyocytes from the hearts of 1 -3 d old neonatal rats were prepared by a modified method. Five groups were included in the study: control; hypoxia/ reoxygenation; hypoxia/reoxygenation + CT - 1; CT - 1 + hypoxia/reoxygenation + LY294002 (PIK3/Akt inhibitor) ; CT -1 + hypoxia/reoxygenation + PD98059 (ERK inhibitor) ; CT - 1 + hypoxia/reoxygenation + DMSO. The concentration of CT -1 was 10 μg/L. The survival rate of myocytes was evaluated by MTS method. Apoptosis, mitochondrial permeability transition pore ( △ψm) and reactive oxygen species ( ROS) were detected by flow cytometry. Nox - 1 protein was determined by Western blotting. RESULTS: Apoptosis of cardiomyocytes and the level of ROS (19.7% ±1.4% vs 2.1% ± 0.5% , 14.07% ± 1.25% vs 3.54% ± 0.86% , P < 0.05 ) increased markedly after hypoxia/reoxygenation, but cardio-myocyte survival rate and the level of△ψm (40.55% ±4.25% vs 86.28% ±7.15% , P <0.01) decreased significantly. The expression of nox - 1 protein was upregulated markedly. With CT - 1 intervention, cardiomyocyte survival rate increased markedly, apoptosis, both ROS and expression of nox - 1 protein reduced significantly. The level of△ψm increased obviously. The effect of CT - 1 was inhibited by LY294002.No significant effect was observed on cells survival in DMSO group, which confirmed that LY294002 was specifically involved in blocking the protective effect of CT - 1.CONCLUSION : The expression of subunit of NADPH oxidation enzyme complex nox - 1 protein is upregulated markedly in cardiocyte hypoxia - reoxygenation injury.CT - 1 protects cardiac cells against hypoxia - reoxygenation injury by downregulating the expression of nox -1 protein to decrease the level of ROS.

Depression is a serious mental illness with a high incidence. At present, we do not fully understand the specific pathological mechanisms of depression, and the efficacy of drug treatments is very limited. Recent studies have shown that epigenetic changes that occur in specific brain regions may be a key mechanism by which environmental factors to interact with individuals to influence the risk of depression. Therefore, drugs that target epigenetic regulation may become a new direction for the development of antidepressants. Histone deacetylase inhibitors (HDACi) are a class of compounds that inhibit histone deacetylase activity, which has been reported to be associated with depression; this article addresses the use of HDACi in preclinical studies, and their potential therapeutic role and limitations of use in depression.

OBJECTIVETo describe the changes of health related behavior and influencing factor during and after the prevalence of severe acute respiratory syndrome (SARS), as to providing evidence for inducing public health related behavior to cope with the emergent infectious public health hazards.
METHODSAccording to the epidemic strength of SARS, Guangzhou, Taiyuan, Hangzhou were selected to be the research areas, and convenience sampling was used to identify 200 city residents, 200 country residents and 400 occupational populations from each area. The uniform and self-made questionnaire was carried out by about 2400 residents.
RESULTSAll 2424 subjects completed the questionnaire. The correlation coefficient of scores of health related behavior during and after SARS was 0.782 (P < 0.01). And 39.3% subjects were considered as under the health risked stress by CPSS. Multiple linear regression indicated that the scores of health related behavior were significantly related to the perceived stress, demographic characteristics and recognition of SARS.
CONCLUSIONSThe public health related behavior should be developing in the SARS, and part of health related behavior had been kept after SARS and part been decreased. Behavior change should depends on the prevalence of the disease, cultural heritage and behavior variability. More attention should be paid to induce the public psychology and behavior and enhance the degree of recognition on related knowledge through health education as to relieving the stress in populations when we conduct to cope with the emergent public health hazards.

OBJECTIVETo find out the perceived stress in general public during prevalence of severe acute respiratory syndrome (SARS) and its impact on health behavior.
METHODSA retrospective survey was conducted in Guangzhou, Hangzhou, and Taiyuan according to the epidemic situations of SARS, and 2532 subjects were randomly selected from constructive industry, school, and commercial business and residents in urban and rural areas. The perceive stress was measured by Chinese perceived stress scale (CPSS), and health related behavior during SARS was tested by uniform and self-made questionnaire. EpiData 2.0 was used for data management and CPSS value was calculated according to answer to 14 questions contained in the scale. Health risk stress among different population group and health related behavior among low, medium and high stress state were analyzed by SPSS 11.5.
RESULTS2424 subjects were involved in the survey. The CPSS value was measured from 0 - 49 (22.7 +/- 6.8), M = 24.0. 39.3% (953/2379) subjects were under the health risk stress. The health related behaviors such as washing hands, opening the window for air, keeping away from others when cough and sneeze, doing exercises etc were reduced with the stress increased. Logistic regression indicated that compared with the persons with the thoughts of nothing serious of SARS, without any dread of SARS, and knowing nothing about prevention of SARS, the perceived stress was significantly related with perceiving of the thread to certain extent (beta = 0.41, Wald chi(2) = 4.84, P = 0.03), worrying little about the epidemic (beta = 0.50, Wald chi(2) = 6.69, P = 0.01), worrying about it to certain extent (beta = 1.39, Wald chi(2) = 48.59, P = 0.00) and scared so much (beta = 1.77, Wald chi(2) = 53.59, P = 0.00), and knowing little about the prevention (beta = 0.74, Wald chi(2) = 4.48, P = 0.03), knowing something about prevention (beta = -0.98, Wald chi(2) = 8.29, P = 0.00) and knowing the prevention very well (beta = -1.18, Wald chi(2) = 10.66, P = 0.00).
CONCLUSIONThe adoption of health related behaviors declined with increase of perceived stress. Opening connection to authority and government, enhancing the awareness of outburst affairs among general public and providing positive social support may be effective ways to reduce the population perceived stress.

Objective To ohserve the rat myocardial damage induced by citreoviridin(CIT)in the status of combined selenium and protein deficiency.Methods According to 2×2 factorial design,forty 4-week-old healthy Wistar rats were randomly divided into four groups.i.e.combined selenium and protein adequate with no CIT and with some CIT groups(Se+Pro+CIT-.Se+Pro+CiT+),combined selenium and protein deficiency with no CIT and with some CIT groups(Se-Pro-CIT-,Se-Pro-CIT+).The numbers of male and female were fifty-fifty.Theserats were fed with combined selenium and protein adequate and combined selenium and protein deficiency fodder until the 16th week. Cardiac toxicity of CIT was evaluated by general state of health, heart weight index, myocardial pathological change, the levels of selenium and the activities of glutathion peroxidase (GSH-Px) and creatine kinase (CK) in serum, and the activity of superoxide dismutase(SOD) of myocardium. Results The interaction effects of combined selenium and protein deficiency and adequate CIT on body weight, serum levels of selenium and albumin, heart weight index, the activities of CK and GSH-Px in serum and SOD of myocardium were statistically not significant(F= 0.000, 1.210, 0.625, 0.981, 2.785, 0.074, 0.001, all P> 0.05). The main effects of combined selenium and protein on the levels of serum selenium and albumin, heart weight index and the activity of GSH-Px in serum were statistically significant(F = 507.698, 87.734, 4.201, 109.389, all P < 0.05). The main effects of CIT on body weight, the levels of serum selenium and albumin, heart weight index and the activity of CK in serum were statistically significant(F = 10.929, 4.371, 26.108, 24.844, 4.439, all P < 0.05). The mean levels of serum selenium of Se-Pro- groups [(70.4 ± 40.0), (87.7 ± 59.6 )μg/L] were lower than those of Se+Pro+ groups [(446.1 ± 74.8),(502.1 ± 39.2)μg/L, all P < 0.05]. The mean levels of serum albumin of Se-Pro- groups [(34.36 ± 1.28 ), (33.38 ±2.48)g/L] were lower than those of Se+Pro+ groups[(40.69 ± 1.30), (38.71 ± 2.15)g/L, all P < 0.05]. The mean levels of heart weight index of CIT+ groups[(4.14 ± 0.36) × 10-3, (4.39 ± 0.53) x 10-3] were higher than those of CIT-groups[(3.56 ± 0.26) x 10-3, (3.80 ± 0.28) x 10-3, all P < 0.05] respectively at the same levels of selenium and protein. The mean levels of CK in serum of Se-Pro-CIT+ group[(2.54 ± 0.56)kU/L] was lower than that of Se-Pro-CIT- group [(3.37 ± 0.67 )kU/L, P < 0.05]. The mean levels of activity of GSH-Px in serum of Se-Progroups[(408.1 ± 412.6), (510.5 ± 392.0)U/L] were lower than those of Se+Pro+ groups[(1667.8 ± 102.2),(1731.5 ± 144.4)U/L, all P < 0.05]. In Se+Pro+CIT+ group, there was part of intercalary disc of cardiac myocytes fragmented;the conjunctions between myoeytes were broken;in some region, cardiac myocytes became edematous,even dissolved. In Se-Pro-CIT- group, the change of cardiac myocytes membrane structures was not obvious;filament structure was disappeared around nucleus;deposition of mass floccule could be seen. In Se-Pro-CIT+ group,the structure of sarcomeres was not obvious;mitochondrial cristae was loosened;cavities in myocytes could be seen occasionally;there were lots of disseminated sareoplasmic reticulum extending. Conclusions .CIT is the main risk factor in inducing myocardial damage. The deficiency of combined selenium and protein can aggravate the damage,but its independent pathogenic effect is weak.
