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 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 study influence of type 2 diabetes mellitus (T2DM) on coronary artery lesion and plaque sta‐bility using optical coherence tomography (OCT) in patients with coronary artery disease (CAD) manifesting unsta‐ble angina pectoris (UAP) . Methods :A total of 200 patients diagnosed as CAD manifesting UAP were selected.According to complicated with diabetes mellitus or not ,they were divided into normal blood glucose group (n=98) and complicated T2DM group (T2DM group ,n=102). Coronary angiography (CAG) and OCT were used to eval‐uate coronary artery lesion ,assess plaque nature and measure the thickness of plaque fibrous cap in order to confirm plaque stability . Results:Compared with normal blood glucose group ,there were significant rise in percentages of multi-vessel coronary disease (48.98% vs. 78.43% ) ,severe artery stenosis (20.57% vs. 40.21% ) ,lipid plaques (25.00% vs. 39.84% ) and plaques with fibrous cap thickness <65μm (25.93% vs. 45.24% ) in T2DM group , P<0.05 or < 0.01 .Conclusion :Patients with coronary artery disease have more severe coronary artery lesion and high ‐ er incidence rate of multi‐vessel coronary disease and unstable plaque when complicated with type 2 diabetes mellitus .

Objective To compare the bronchial blocker and double-lumen tube for one-lung ventilation in the elderly patients undergoing minimally invasive direct coronary artery bypass (MIDCAB).Methods Thirty six patients of both sexes,aged 65-78 yr,with the left ventricular ejection fraction ≥ 45％,with body mass index ＜ 30 kg/m2,of ASA physical status Ⅱ or Ⅲ (NYHA Ⅰ-Ⅲ),scheduled for elective MIDCAB in the left thorax,were randomly divided into 2 groups (n =18 each):double-lumen endotracheal tube group (group D) and bronchial blocker group (group B).Anesthesia was induced with midazolam 0.05 mg/kg,etomidate 0.3 mg/kg,fentanyl 10μg/kg and cisatracurium 0.15-0.20 mg/kg.The patients were intubated with a left-sided double-lumen endotracheal tube 5 min later in group D.The patients were intubated with a single-lumen endotracheal tube 5 min later,and then Coopdech bronchial blocker was inserted into the primary bronchus in group B.The patients were mechanically ventilated.Before induction of anesthesia,at 2 min before intubation,immediately before and after intubation,and at 1 and 2 min after intubation,mean arterial pressure (MAP),heart rate (HR),and mean pulmonary arterial pressure (mPAP) were recorded and rate-pressure product (RPP) was calculated.The requirement for vasoactive drugs was recorded during induction of anesthesia.Lung collapse developed after the pleura was opened was also recorded.Surgical exposure was scored at the end of operation.Results Compared with group D,MAP,HR RPP and mPAP were significantly decreased after intubation,the requirement for nicardipine and esmolol was decreased,and no significant change was found in the requirement for atropine and metaraminol,rate of lung collapse and score of surgical exposure in group B.Conclusion Compared with doublelumen tube,bronchial blocker can provide sufficient exposure of the surgical filed,and intubation-induced fluctuation of hemodynamics is small in the elderly patients undergoing MIDCAB.

Objective To analyze and determine the clinical chatacteristics and treatment of suqerior mesenteric venous thrombosis.Methods We reviewed the medical records of all 32 patients who were diagnosed as with SMVT in Peking Friendship Hospital from 1985 to 2005.Results Thirty-two patients were diagnosted as SMVT,11 patients were with chronic superior mesenteric venous thrombosis(median age 46.6 years,ranging 32～78 years),without acut abdomen;22 cases were acute superior mesenteric venous thrombosis(median age 45.9 years,range 19～64 years).The main symptoms at the presentation were abdominal pain(100%),abdominal distension(100%),acute abdomen(100%),vomiting(68.2%,15/22),an fever(36.4%,8/22).Misdiagnosis rate 59.1%(13/22),death rate 31.8%(8/22).Conclusion The presentations of ASMVT have some relatively characteristics.The clinical diagnosis of ASMVT can be confirmed on the basis of abdominal CT and selective superior mesenteric arteriography in early phase.

Objective To study on comparison of different age group patients with acute abdomen who received laboratory check-ups.Methods 126 patients with acute abdomen were divided into 0.05).2.Of 126 patients,65 cases(51.6%)received abdominal B ultrasonography check-up,among which 41 cases(44.1%)were in
