Chemotherapy and correlated treatments for primary bepatocarcinoma make great progress in recent years. Further studies for transarterial chemoembolization are investigating the new available embolization agents and drug eluting beads to improve the effect on tumor necrosis. Percotaneous ethanol injection for small hepatocellular carcinoma may be regarded as first line treatment. Hepatic arterial infusion and systemic chemo-therapy should also be considered further study.

The medical students are the future medical talent,so they need medical ethics education.This thesis lists medical students' cognitive bias on medical ethics study and enlightens some effective measures on it to achieve the educational purpose.

ObjectiveTo explore the expressions of EGFR and Ki-67 in vulvar dystrophy and their clinical significance MethodsTissue specimens were collected from 160 patients with vulvar dystrophy.Immunohistochemical method was used to detect the expressions of EGFR and Ki-67 in these specimens.The expression levels of EGFR and Ki-67 were compared among different pathological subtypes of vulvar dystrophy,and the relationship of these expressions with clinical pathological characteristics was assessed.ResultsNo significant differences were observed in the expressions of EGFR or Ki-67 between vulvar dystrophy of squamous cell hyperplasia type,lichen sclerosus type and mixed type(P ＞ 0.05).The expression level of EGFR was positively correlated with that of Ki-67 in vulvar dystrophy (r =0.66,P ＜ 0.05).There was a significant difference in the expression rate of EGFR and Ki-67 between patients with different courses of vulvar dystrophy(both P ＜0.05),but not between patients with different age at onset of vulvar dystrophy(both P ＞ 0.05).Conclusion The expressions of EGFR and Ki-67 are different among patients with different courses of vulvar dystrophy.

Objective To establish the quality standard of Huangqi-Changyu'an capsule. Method Thin layer chromatography was used to identify psoralen, evodia mtaecarpa, and nutmeg in Huangqi-changyu'an capsule. HPLC was used to determine the content of psoralen. A Hypeisil BDS C18 column(200 mm×4.6 mm,5 μm) was used with mobile phase consisted of acetonitrile-water (30:70) at the rate of 1 ml/min. The detection wavelength was set at 245nm with the column at room temperature. Results The liner range of psoralen was 3.572~53.58 μg/ml (r=0.999 9) with average recoveries of 99.04%, and the RSD was 0.8%. The liner range of isopsoralen was 3.796~56.94 μg/ml (r=0.999 9) with average recoveries of 99.20%, and the RSD was 0.6%. Conclusion This method is sentivive, accurate and rapid for the quality control of Huangqi-Changyu'an capsule.

Objective To explore the influence of vacuum sealing drainage(VSD) technology in snake bite treatment.Methods 108 patients of snake bites need to incision decompression were randomly divided into two groups,VSD group (VSD) 58 cases,conventional group (wound change dressings ordinarily) 50 cases.The secondary suture of time,the number of change dressings,material consumption fees,antibiotics use cost,wound infection rate,in hospital,average length of hospital stay were compared between two groups.Results Compared the VSD group with the conventional group,the secondary suture of time (t =11.743,P ＜ 0.05),the number of change dressings (t =50.661,P ＜ 0.05),material consumption fees (t =9.054,P ＜ 0.05),antibiotics use cost (t =21.515,P ＜ 0.05),wound infection rate (x2 =9.155,P ＜ 0.05),in hospital,average length of hospital stay (t =10.350,P ＜ 0.05) had significant differences.Conclusion VSD technique can be a ideal way to treat snake bites patients and worth popularizing at this stage.

The paper analyses the function of mutual communication in solving physician-patient conflict. Some feasible suggestions on the mutual communication between doctors and patients are also raised in order to solve the physician-patient conflict effectively.

OBJECTIVE To explore uticozation of nursing care in the operating room disinfection and isolation management. METHODS The nurses and doctors operating room were selected as the observers. Obsening in the operating room for 30-60 min, and recorded the results. After the guidance of the staff discussed to address the problem. RESULTS From June 2006 to June 2008, observed in disinfection and isolation problems of operating room management. The measures include 45 long-term plan, measures need to improve the implementation. To continue to reduce the existing problems, the increasing outstanding operation; Operating room working environment, surgical sterilization materials, sterile technique quality control inspection pass rate in 2006 from the third quarter of 94.2%, 97.1%, 95.1% to 2008 second quarter of 100.0%, 100.0%, 99.8%. CONCLUSIONS The meause can improve the initiative to participate in the management increase the communication between the department and surgery, disinfection and isolation technology improve the quality of management effectiveness. Disinfection and isolation of the operating room are needed to ensure the effectiveness of management to prevent nosocomial infection.

This paper introduces a new perspective of case choice in medical ethics teaching,which breaks through the limitations of the choice of teaching cases,chooses the hot-case analogy teaching methods out of medical field,and proves to have received good teaching results.

Objective To review the clinical and laboratory characteristics of the hemohemocytopenia diseases in children ,in or-der to improve the understanding of the related diseases and the level of diagnosis and treatment .Methods A total of 217 children with hemocytopenia diseases with one ,two or three series of cell reducing ,and the degree of blood cells reduce with anemia and common diseases in children .Results In 185 cases with the hemocytopenia diseases ,1 series reduce were mainly in idiopathic thrombocytopenic purpura(ITP ,37 .2% )、thrombocytopenia (19 .8% ) ,granulocytopenia or agranulocytosis (9 .1% ) .2 series re-duces mainly in acute leukemia (43 .6% ) ,the IT P (21 .7% ) and aplastic anemia (6 .5% ) .3 series reduce mainly in acute leukemia (38 .9% ) and aplastic anemia(33 .6% ) .Common cause of anemia in children with 180 cases of hemohemocytopenia diseases were a-cute leukemia (20 .0% ) ,the ITP(19 .4% ) and no clinical diagnosis of anemia (16 .1% ) .Conclusion After analyzing the character-istics of the patient′s clinical and laboratory in 217 cases of hemocytopenia diseases ,improve the clinical blood disease related knowl-edge ,help understand the laboratory data and proportion .

Objective To investigate the effects of antisense phosphothioate oligodeoxynucleotides (AS-ODNs) W086 on drug-resistant gene CTX-M expression in Escherichia coli producing extended-spectrum β-lactamases(ESBLs).Methods AS-ODNs liposome was introduced into the purpose bacteria B052.The total colony forming unit(CFU) was counted.The bacteria growth curve was drawn by microplate reader.The inhibition effects of AS-ODNs on the expressions of drug-resistant gene CTX-M were observed by RT-PCR in B052.The minimal inhibitory concentration(MIC)was determined by fluid dilution method.Results significant growth inhibition of cells treated with W086 was observed as compared with those in cells in control treated bacteria.The number of B052 colonies significantly decreased in all W086 treated groups in a concentration dependent manner (P ＜ 0.05),while CFU of B052 was not influenced in simple liposome group,simple W086 group and controlled chain group.The expression of CTX-M was selectively inhibited.Conclusion Efficiently and specificly blocking expression of CTX-M mRNA,AS-ODNs reverses the multiple drug resistance of B052.It indicates that AS-ODNs provides a new viable strategy to reverse antibiotic resistance problem.
