A multi-stage stratified sampling method and a self-designed questionnaire were used to evaluate the prevalence of conjunctivitis symptoms and associated factors among the Beijing residents.In total,12 890 residents aged over 18 years were recruited from 6 districts.The reported prevalence of conjunctivitis symptom at the last years was 1.60％.Self-reported health condition and personal health behaviors were risk factors associated with conjunctivitis among adult Beijing residents.No significant difference existed between different districts,age groups,educational levels,gender and races.Conjunctivitis symptom among Beijing residents was related with health condition and health behaviors.More measures should be taken to cultivate the health model of behaviors.

Objective To discuss the role of interleukin (IL)-12 in capillary bronchiolitis disease.Methods Fifty-nine cases of capillary bronchiolitis children under 2 years old were enrolled as the bronchiolitis group Ⅰ(n =28) and bronchiolitis group Ⅱ(n =31),36 cases of children with bronchopneumonia of the same age and 31 cases of children suffered from non-infectious diseases such as hernia and renal calculus of the same age were enrolled as bronchopneumonia control group and normal control group respectively.The peripheral blood IL-12 levels of four groups were detected by enzyme-linked immunosorbent assay.Results The levels of the peripheral blood IL-12 in bronchiolitis group Ⅰ,bronchiolitis group Ⅱ,bronchopneumonia control group and normal control group were (34.72±7.96) pg/ml,(55.30 ±6.72) pg/ml,(56.79±10.36) pg/ml and (61.23 ± 11.51) pg/ml respectively.The level of the peripheral blood IL-12 in bronchiolitis group I was significantly lower than that in bronchiolitis group Ⅱ,bronchopneumonia control group and normal control group respectively (P ＜0.05),and the level of the peripheral blood IL-12 in bronchiolitis group ⅡⅡ was significantly lower than that in bronchopneumonia control group and normal control group respectively (P ＜ 0.05),but there was no significant difference between bronchopneumonia control group and normal control group (P ＞ 0.05).Conclusion The level of IL-12 is one of the important factors for bronchiolitis disease,the reducing of serum level of IL-12 in children who have a high risk factor of capillary bronchiolitis is more obvious.

Background:Chronic atrophic gastritis(CAG)is a kind of chronic gastritis with atrophic changes of gastric mucosa. The studies on peripheral blood biomarkers in CAG are rare. Aims:To investigate the methylation of peripheral blood CpG sites in Runx3 gene promoter region in CAG patients. Methods:Eighty-two mild CAG patients,73 moderate to severe CAG patients from June 2013 to May 2014 at Daqing Oilfield General Hospital were enrolled,and 45 patients with normal gastric mucosa were served as controls. The methylation of CpG sites in Runx3 gene promoter region was measured by MALDI-TOF-MS. mRNA expression of Runx3 was determined by fluorescent quantitative PCR,and the protein expression of Runx3 was determined by Western blotting. Results:Compared with the control group and mild CAG group,methylation levels of CpG13,CpG14 and CpG15 sites in Runx3 gene promoter region were significantly increased in moderate to severe CAG group(P < 0. 05),the mRNA and protein expressions of Runx3 were significantly decreased( P < 0. 05). No significant differences in methylation of CpG sites in Runx3 gene promoter region and mRNA and protein expressions of Runx3 were found between mild CAG group and control group( P >0. 05 ). Conclusions:The hypermethylation of peripheral blood CpG13,CpG14 and CpG15 sites in Runx3 gene promoter region can inhibit the expression of Runx3 in CAG patients,and can be used potentially as the biomarker for clinical staging of CAG.

Objective To observe the effect of aerobic exercise of different intensities on type Ⅱ collagen,glycosaminoglycan (GAG) and chondrocyte apoptosis in rabbits modeling knee osteoarthritis (OA),so as to explore the preventive effect and its possible mechanism.Methods Twenty healthy New Zealand white rabbits were randomly divided into Groups A,B,C and D,each of 5.Group A was allowed free activity in a cage for 9 weeks.Group B was allowed free activity for 4 weeks,then an OA model was established using papain and confirmed via MRI 1 week later,Another 4 weeks of free activity were then allowed.Groups C and group D were given running training for 20 minutes a day at 0.5 km/h,3 times a week,and then 20 minutes a day at 1.5 km/h,5 days a week on a treadmill for 4 weeks.Nine weeks later,all 4 groups of rabbits were killed and the articular cartilage damage of each group was compared using Mankin scoring,and expression of type Ⅱ collagen,GAG content and chondrocyte apoptosis in the cartilage.Results After the intervention,the average Mankin score,expression of type Ⅱ collagen and GAG content of groups B,C and D were significantly lower than those of group A,and all of those values in group B were significantly lower than those of group D.After 9 weeks the chondrocyte apoptosis rate of group A was significantly lower than that of the other groups,and that of groups C and D was significantly lower than that of group B.Conclusion Aerobic exercise may prevent knee articular cartilage degeneration through inhibiting reduction in the amount of type Ⅱ collagen and GAG in the cartilage matrix.It may be related to decreasing the chondrocyte apoptosis.

Objective To study the sensitivity and specificity of the Chinese eating assessment tool (EAT-10) in screening acute stroke patients for oropharyngeal dysphagia (OD).Methods A total of 130 inpatients with acute stroke were screened using the Chinese EAT-10.On the same day they were also screened using the gold standard technique for diagnosing dysphasia-videofluoroscopy.A receiver operating characteristics (ROC) curve was developed to study EAT-10's sensitivity and specificity.A Youden index,positive predictive value (PPV),negative predictive value (NPV),and positive and negative likelihood ratios (LHR+ and LHR) were quantified.Results According to the ROC curve,a cut-off point of 1 (EAT-10 score≥ 1) gave the best sensitivity (77.9％),the highest NPV (73.2％),with 66.1％ specificity,71.6％ PPV,2.30 LHR+ and 0.33 LHR in screening for OD.The test-retest reliability was above 0.7.An investigator consistency reliability test showed good repeatability,and the consistency between each item and the mean total score was high.Conclusion The Chinese EAT-10 has good test-retest reliability and investigator consistency.The optimal cut-off point is 1,with good sensitivity and NPV at scores ≥ 1.The test can be recommended as a screening tool for OD in acute stroke patients.

To assess the level of health skills relating to infectious diseases among residents in Beijing and develop more effective strategies for controlling infectious diseases.We conducted a multistage sampling,retrospective cross-sectional survey of residents aged 18 and above from 6 districts by selfadministered and anonymous questionnaires in January 2011.The questionnaires consisted of health skills relating to infectious diseases.A total of 13 042 respondents completed the survey.The proportions of people with the skills for acquiring knowledge about infectious diseases,being able to read medicinal package insert,being able to read brochures with regard to basic knowledge about infectious diseases, being able to read laboratory test report andproper use of thermometer were 57.7％,71.0％,70.2％,47.9％ and 76.8％ respectively.The levels of health skills were different among different populations (P ＜0.01).A low level of health skills was observed among the poorly-educated people and elders.Therefore measures such as health education and skills training about infectious diseases should be taken to improve the health skills.

Aim To investigate the effects of Rehmannia glutinosa oligosaccharides(ROS)on the damage induced by glutamate in hippocampal neurons.Methods The neurons isolated from hippocampus in new born SD rats were cultured for 7~9 days,which were specifically stained with NSE and then randomly divided into four groups:(Ⅰ)Normal cultures(control);(Ⅱ)ROS control cultures;(Ⅲ)Glutamate-exposed control cultures;(Ⅳ)Glutamate-exposed cultures pretreated with ROS.The neurons morphology was observed under inverted microscope;cell viability was assayed by MTT staining;LDH release was detected with chromatometry and flow cytometric analysis for identification and quantification of cell apoptosis.Results Compared with normal group,after exposure of glutamate for 24 h,the viability of neurons was decreased,LDH release and cell apoptosis were increased(P
