The thesis put forward a feasible method for the communication between teachers and students in the process of hospital personnel training based on comprehension.This approach named‘dialogue’,can adjust the conflict between teachers and students including‘the conflicts between teaching and studying’,‘distraction of teachers’and‘halfhearted students’,etc.Applying‘dialogue’method to resolve conflicts provided a new angle for better understanding of relationship between teachers and students.

Formation of coronary atherosclerotic plaques brings severe damage to human health.Macrophages play an important role during formation and development of plaques,which becomes an important marker for judging whether atherosclerotic plaques are stable or not.Therefore,recognition and quantification of macrophages become hotspot in current study.The present article made an overview on cunent frequently-used imaging techniques for de-tecting coronary plaques and macrophages inside them for now.

Objective To understand the combined effects of selenium (Se), germanium (Ge) on the level of Ca, Mg, Zn in the tissues of rats exposed to fluoride(F). Methods SD rats were divided into 5 groups and respectively treated with distilled water(control), 100 mg NaF/L(through drinking water), based on the fluoride treatment, Se, Ge were respectively given by gavage at the doses of 0.1 mg Na2SeO3/(kg?d), 10 mg Ge-132/(kg?d) and 0.1 mg Na2SeO3/(kg?d) plus 10 mg Ge-132/(kg?d) for 90 days. The body weight, activity, and general state were observed. The content of Ca,Mg,Zn in the serum,liver and kidneys were determined by flame atomization method. The content of F was detected by ion chromatography. Results The body weight in F+Se, F+Ge and F+Se+Ge groups were higher than that in F group and lower than that in the control group. The content of F in the liver, kidney in F+Se, F+Ge groups were higher than that in F+Se+Ge group(P

Perinatal cardiomyopathy is a kind of idiopathic cardiomyopathy ,its morbidity rate is low but it may re‐sult in death . The present article made a review on etiological researches of perinatal cardiomyopathy of recent years ,aiming at providing assistance for clinical diagnosis and therapy .

Objective To explore the association of IL-10-592A/C polymorphism with the susceptibility to respiratory syncytial virus(RSV) bronchiolitis and disease severity,and to explore the impact of IL10-592A/C polymorphism upon total serum IL-10 levels in children with RSV bronchiolitis. Methods One hundred children (patients group) admitted to hospital with RSV bronchiolitis and 100 healthy children (control group) were recruited. PCR restriction length fragment polymorphism assay was used to detect the single nucleotide polymorphisms of IL-10-592A/C. Total serum IL-10 levels in patients group were assayed with ELISA. Results The genotype frequency of IL-10-592A/C were AA 44% ,AC 38% ,CC 18% in patients group ,and AA 41% ,AC 42% ,CC 17% in the control group,it showed no significant difference between two groups (χ2= 0. 33, P > 0. 05) . The frequency of each allele were A 63%, C 37 % in patient group, and A 64% ,C 36% in the control group,there was no significant difference in allele frequency between two groups (χ2=0. 43 ,P >0. 05) . There was no significant difference in total serum IL-10 levels between different genotype of IL-10-592A/C (F = 0. 87, P > 0. 05) . The differences in genotype frequency of IL-10-592A/C were not significant between mild and moderate to severe cases (χ2= 2. 67, P > 0. 05) . Conclusion IL-10-592A/C gene polymorphisms do not correlated with RSV bronchiolitis.

K-ras gene is one of oncogenes,which promotes cells growth and differentiation.Ras protein loses the activity of GTP enzyme because of K-ras mutations,and that may cause abnormal growth,differentiation of cells and promote the occurrence of tumor.Patients with colorectal carcinoma that carry mutations in K-ras gene do not benefit from the administration of anti-epidermal growth factor receptor (EGFR) polyclonal antibodies.Different solid tumors of colorectal carcinoma have different K-ras mutation rates.Different genotypes of K-ras gene (wild-type or K-ras mutant type) affect significantly on treatment options and prognosis.The efficacy of mutant type patients with anti-EGFR antibodies is poor,and the therapeutic effects of 5-FU and FOLFOX are still unclear.

Objective To explore the effects of psychological disorders on qualityoflife of elderly patients with non-erosive reflux disease (NERD) under maintenance treatment of proton pump inhibitors (PPIs). Methods A total of 76 elderly patients with NERD treated by proton pump inhibitors (maintenance treatment of Esomeprazole over half a year) were enrolled. They were classified into symptom group aged (66.5±8.2) years (n=35) and symptom group aged(68.2+6.9)years (n=41)according to reflux symptoms,with 20 healthy people aged(65.4 ±8.8)years as control.The subjects completed the questioniaires on psychological status including self-rating anxiety scale (SAS) and self-rating depression scale (SDS) and their quality of life was evaluated by gastroesophageal heath related quality-of-life instrument(GERD -HRQL) and medical outcomes study short form(SF-36). Results Scores of SAS and SDS were significantly higher in symptom group (54.9±6.2,57.9±8.6) than in symptomless(37.9±8.7,42.7±7.9) and health control group (38.9± 7.2,43.1 ± 8.9),all (P＜0.05),but there was no difference between symptomless and health control group.The rates of anxiety and depression in symptom group (51.4％,57.1％) were increased as compared with symptomless (12.2％,9.8％)and health control group(0.0％,5.0％).Scores of GERD HRQL in symptom group were higher than in symptomlcss group (21.4± 5.0 vs.4.5±2.2,t=19.76,P＜0.01)while the indexes such as body pain,vitality,social function,affection,mental and whole health in score of SF-36 besides physiology function were lower in symptom group than in symptomless and control groups (P＜0.05 or P＜0.01 ).Only the significant differences in mental and whole health of SF-36 were found between symptomless and control groups (P＜0.01).Correlation analysis revealed that SAS and SDS scores were positively correlated with scores of GERD-HRQL in symptom group(P＜0.01) and negatively with all dimensions of SF-36 but physical function (P＜ 0.05). Conclusions Most of elderly symptomatic patients with NERD treated by PPI are in psychological disorders which results in lower quality of life.
