This review was made to compare the multimedia teaching results with traditional teaching results in medical universities or colleges.Two kinds of opposite viewpoints appeared:the multimedia teaching results was better or worse than the latter.

Objective To provide reference for the clinical application of preoperative autologous blood donation(PABD).Meth-ods 34 patients met the conditions of PABD,and underwent PABD were enrolled in the study.Five laboratory indicators include Hemoglobin(Hb),RBC,WBC,PLT)and hematocrit(HCT),and prepared blood volume before surgery,intraoperative and postop-erative reinfusion volume were recorded before blood collection and after reinfusion.Results In the patients who only underwent PABD(A group),compared between before blood collection and after blood transfusion(intraoperative or postoperative 24 h),all the five Hematology Index were statistically different(P <0.05).The RBC,Hb,HCT,PLT were decreased(P <0.05),while WBC increased(P <0.05).In patients underwent both PABD and allogeneic blood transfusion blood(group B),the five laboratory indica-tors showed a similar pattern:RBC,Hb,HCT,PLT decreased (P <0.05),while WBC increased(P <0.05).In the comparison be-tween the two groups,the five indicators before blood collection and after reinfusion were not statistically different(P >0.05).Con-clusion The effective of PABD application in surgical patients undergoing elective operation is good,which won′t cause harm to the patient′s body(reflected in the hematology indicators).However,in some cases preoperative assessment of blood loss is not accurate enough,result in the amount of blood collected before operaton not meeting the needs,which might impact the effect PABD.

OBJECTIVEThis study aims to investigate the prevalence and distribution of teeth number and morphology abnormalities in Chinese pediatric patients' permanent teeth at the mixed dentition stage by performing panoramic radiographs analysis.

METHODSA total of 4 347 panoramic radiographs of pediatric patients aged 5 years to 15 years who were admitted to the hospitals from September 2011 to September 2013 were reviewed. The presence of teeth number and morphology abnormalities were recorded as follows: congenitally absent teeth, supernumerary teeth, odontoma, microdontia, fused teeth, dilaceations, and cusp deformity. SPSS 16.0 software was used for statistical analysis.

RESULTSThe prevalence of teeth number and morphology abnormalities in pediatric patients' permanent teeth was 31.79% (1,382/4,347). The prevalence was higher in males. Significant difference between the genders was observed (P < 0.05). Tooth agenesis, the most frequent dental anomaly (15.00%, 652/4,347), was considerably common in females; supernumerary teeth (12.61%, 548/4,347) followed, which was significantly common in males. Both differences were statistically significant (P < 0.05). The levels of prevalence of both microdontia and dilacerations were 4.00% (174/4,347) and 2.16% (94/4,347). The prevalence of cusp deformity, odontoma, and fused teeth were relatively low at 0.74% (32/4,347), 0.51% (22/4,347), and 0.39% (17/4,347), respectively.

CONCLUSIONThe prevalence of teeth number and morphology abnormalities in children's permanent teeth at the mixed dentition stage is apparently high. Tooth agenesis and supernumerary teeth are the most frequent. Panoramic radiograph is an efficient method for the early diagnosis of teeth number and morphology abnormalities. This method can assist pediatric dentists to formulate treatment plans for children at the appropriate time.

20 first mandibular premolars were randomly divided into 2 groups(n =10).The teeth in experimental group were treated by fi-ber main post in combination with auxiliary pile,in control group by single fiber main post,and then were restored by metal crown.They were fixed in universal testing machine.The fracture load(N)of experimental and control group was (846.50 ±40.33)and (437.90 ±41.15) respectively(P <0.01).

Objective To study the proper desiccation and the expiry date for humidifier after disinfection, and then decline the incidence rate of infection in hospital. Methods Divided 84 humidifiers into the A and B groups randomly after disinfection, there were 42 humidifiers in the each group. The natural desiccation was used in the A group, the oxygen desiccation was used in the B group. Monitored the humidifiers of the two groups respectively lasted 7 days, and then compare the datum between them. Results The expiry date of the humidifiers which have dried by natural desiccation was longer than that of humidifiers which have dried by oxygen desiccation. Conclusion We should set down the expiry date for humidifier according to the different desiccation and the different seasons.

Objective To study the psychosocial behavior reaction,psychosocial needs,anxiety and depression among colostomy patients prior to discharge and to explore the relationship between them.Methods Totally 67 colostomy patients from 2 hospitals in Guangzhou were recruited and investigated by demographic questionnaire,Ostomy Psychosocial Behavior Reaction Questionnaire,Ostomy Psychosocial Needs Questionnaire,Hospital Anxiety and Depression Scale 1-2 days prior to discharge.Results The psychosocial behavior reaction among coIostomy patients was in the moderate level with the mean score 2.15±0.27.The psychosocial needs were in medium to high level with the mean score 2.09±0.41.About 37.3％ of colostomy patients showed anxiety,while 20.9％ patients showed depression.Significant positive correlation was shown between psychosocial behavior reaction and psychosocial needs(r=0.565,P＜0.01),while significant positive correlation was also shown between psychosocial behavior reaction and anxiety-depression(r=-0.472,-0.319,P＜0.01).Psychosocial needs and anxiety could predict psychosocial behavior reaction positively(β=0.486,-0.375,P＜0.01).Conclusion The positive acknowledgement and reconstruction are the main psychosocial behavior reactions prior to discharge in colostomy patients.Patients with more psychosocial needs,severe anxiety show more psychosocial behavior reaction.

Objective In order to improve the outcome of surgical treatment for atherosclerotic heart disease,we summarize our clinical experience of surgical treatment during the last four years and propose our therapeutic strategy.Methods A retrospective study was performed including consecutive 1052 patients receiving isolated or combined CABG surgery which was performed by a single surgical team from January 2006 through March 2010 at Fu Wai Hospital.Patients'characters were quantified by European score System for cardiac operative risk evaluation (EuroSCORE).Operative strategies were classified as candioplegic arrest,on-pump beating,isolated off-pump,and the hybrid procedures to treat the concomitnnt diseases,such as peripheral vascular disease,atrial fibrillation,congenital heart diseases,et al.Clinical data including the surgical indications,preoperative patient co-morbidity,postoperative clinical course,and perioperative outcomes were analyzed of.Results Patients showed a mean EuroSCORE of 3.4 ±2.6.There were 127 patients ( 12％ ) with a EuroSCORE ＞6.The mean age of the patients was(61.2 ± 9.5 ) years,ranging from 26 to 84 years.The overall in-hospital postoperative mortality rate was 0％,and all patients had an uneventful recovery course and discharged.The transfusion rate was 31.9％.950 patients (90.3％)were OPCAB and 102 (9.7％) were on-pump CABG.There were 87 patients underwent concomitant CABG and heart valvereplacement or repair.21 patients underwent hybrid procedure by simultaneous peripheral artery stenting and OPCAB,and 14patients underwent redo CABG.The Average number of distal anastomoses was 3.2 ±0.9,and the mean postoperative hospital stay was (7.7 ± 2.5 ) days.Fourteen patients had re-exploration for bleeding,8 with pneumonia,5 with acute renal insufficiency and 6 had intra-aortic balloon pump (IABP) for cardiac dysfunction.All these patients recovered after proper treatment.Conulusion Surgical treatment for the coronary heart disease could achieve satisfactory curative effects by the individualized treatment,technological innovation and strengthen perioperative management.Excellent results and low major complications in the perioperative coupe could be expected through this strategy.

This study is to observe the effect of ilexonin A (IA) on the expression of basic fibroblast growth factor (bFGF) and growth associated protein-43 (GAP-43), and neurogenesis after cerebral ischemia-reperfusion in rats and explore its possible mechanism of protecting neuronal injury. Models of middle cerebral artery occlusion (MCAO) were established in SD rats. Before and after two hours ischemia-reperfusion, IA (20 and 40 mg x kg(-1)) was injected immediately and on 3, 7, 14, and 28 d once a day. The neurological severity was evaluated by neurological severity scores (NSS); neuronal injury in the boundary zone of the infarction area was evaluated by TUNEL and Niss1 staining. The expressions of bFGF and GAP-43 and neurogenesis were evaluated by Western blotting and 5-bromodeoxyuridine (Brdu) fluorescence staining, respectively. After treatment with IA, the NSS of treatment groups were lower than that of the models (3 and 7 d). The number of TUNEL positive neurons decreased and Nissl positive neurons increased at the same time (3 d). The expressions of bFGF and GAP-43 increased significantly in the boundary zone of the infarction area when compared to model group. Moreover, IA markedly enhanced the neurogenesis in the brain after ischemia-reperfusion, which revealed an increase of Brdu/NeuN positive cells in the boundary zone of the infarction area. The possible mechanism of protecting neuronal injury of IA may be related to inhibition on neuronal apoptosis, upregulation of bFGF and GAP-43, and neurogenesis in boundary zone of infarction after cerebral ischemia-reperfusion.
