OBJECTIVE: To investigate the characteristics and influence factors of sensitization hy allergens in patients with allergic rhinitis in the junction of Guangdong and Guangxi provinces. METHOD: One thousand one hundred and twenty-four patients who were diagnosed with allergic rhinitis hy clinical history and symptoms underwent a skin prick test. The percent of allergens with positive skin response and Multiple Allergens Positive Scores were recorded, and their influence factors, included age, gender and test period were evaluated. RESULT: The percent of top three inhalant allergens with positive skin tests were as follow: dermatophagoides pteronyssinus (77.0%) ,dermatophagoides farina (77.1%), blattella germanica (42.3%); the percent of top three ingested allergens with loositive skintests were as follow: crab ( 39.5%), shrimp (31.1%), ribbonfish (10.8%). The average Multiple Allergens Positive Score was (3.6 +/- 2.7). The percent of allergens with positive skin response and Multiple Allergens Positive Score of different allergens changed as age, gender and text period changed, and the changing trend of them was accordant. The percent inhalant allergens with positive skin tests in dermatophagoides pteronyssinus, dermatophagoides farinae and cat fur in different gender showed a significant difference. CONCLUSION Acarine allergens were the most common allergens in patients with allergic rhinitis in the junction of Guangdong and Guangxi provinces. The percent of allergens with positive skin response and the severity of multiple allergy were influenced by age, gender and text period. The severity of multiple allergy can be measured by Multiple Allergens Positive Score.

Objective To discuss the changes of the quality of the fresh frozen plasma,which leaved refrigerator and it was out of the cold chain.Method The fresh frozen plasma was placed at the room temperature,in six different periods,that is 0,0.5,2,4 h,8,and 12 hours.The prothrombin time,activated partial thrombin live enzymes time,fibrinogen and factor FⅤ,factor FⅧ,antithrombin(AT) and protein C were tested on each point.Results In the fourth group and the fifth group,the FⅧ,AT,and protein C were statistically lower compared with the controls (P＜0.05).But there were no obvious changes of APTT,PT,INR,Fbg and FⅤwhen placed at room temperature for 12 hours.Conclusion After the fresh frozen plasma placed at room temperature for more than 8 hours,the FⅧ ∶ C,AT and protein C were significantly lower compared with the control group.But they have no obvious changes of APTT,PT,INR,Fbg and F Ⅴ when placed at room temperature for 12 hours.

As a rising medical science,evidence-based medicine should be extensively used.Applying the principle of evidence-based medicine to the clinical teaching of burns has positive significance for improving teaching quality,which is helpful to the cultivation of students'clinical thinking abilities.

Drug resistance is the main restriction factor for clinical usage of taxanes.This review concentrates on drug-resistance mechanisms of taxanes that include drug target change,avidity change between drug-target interaction,decrease of cellular effective drug concentration,downstream cellular responses to a drug target molecular lesion,and cell cycle regulation-mediated drug resistance.

OBJECTIVE To analyze the relationship of Acinetobacter baumannii in Ningbo No.2 Hospital by pulsed field gel electrophoresis(PFGE) and amplified fragment length polymorphism(AFLP).METHODS The sensitivity of 13 kinds antibacterials were analyzed according to American National Committee for Clinical Labotatory 2004′s Standard.The genotypes were analyzed by PFGE and AFLP.The relationship was analyzed with cluster analysis methods.RESULTS Twenty seven strains of A.baumannii were divided into two groups by AFLP method or into four groups by PFGE method.Cluster analysis showed the concordance.CONCLUSIONS Amplified fragment length polymorphism has more clinical practice.

OBJECTIVE To analyze the existence state of drug-resistant gene,integron and Tn21/Tn501 transposon and the relationship of Acinetobacter baumannii in Ningbo No.2 Hospital by genetic mark.METHODS Twenty seven strains of A.baumannii were clinically isolated.Drug-resistant gene,integron,and Tn21/Tn501 transposon were analyzed using polymerase chain reaction(PCR).The relationship was analyzed with cluster analysis methods.RESULTS The positive rates of blaTEM,blaOXA-23 cluster,blaADC,aac(3)-Ⅰ,aac(6′)-Ⅰ,ant(3″)-Ⅰ,qacE△1-sulⅠ,and intⅠ1 were 81.5%,44.4%,85.2%,85.2%,66.7%,81.5%,85.2%,and 85.2%,respectively.The others were negative.The result of multi-gene cluster analysis showed that the clone transmission existed.CONCLUSIONS The clone transmission of A.baumannii exists in Ningbo No.2 Hospital.The outbreak of A.baumannii may be possible because there are more than 3 clone transmission strains.

Objective The study analyse the multi-drug resistance and epidemiological investigation in Acinetobacter baumannii.Methodes Using,multi-drug resistance gene test,three-dimension test,membranes active efflux test studied multi-drug resistance and epidemiological investigation.The genetype were analyzed by Amplified Fragment Length Polymorphism(AFLP).The strains' homology were researched by multi-gene cluster analysis methods.Results Cluster analysis show that the result of drugsensitive test,multi-drug resistance gene test and AFLP are accordant.The study find at least 3 clones by multi-gene cluster analysis methods.AFLP show that all of the multi-drug-resistance of A.baumannii evolutes from a clone.Conclusions The study combined with clinical practice find that ICU in Ningbo No.2 Hospital now is the core of the arises,evolution,transmission of A.baumannii.Strengthening management of ICU is very important to pretect the prevalence of Acinetobacter baumannii in nosocomial infection.

OBJECTIVE To compare the three methods on relatedness analysis of Acinetobacter baumannii strains in hospital infection.METHODS Twenty-seven A.baumannii strains caused hospital infection were analyzed by pulsed field gel electrophoresis(PFGE),amplified fragment length polymorphism(AFLP) and multiple gene cluster analysis.RESULTS PFGE analysis showed 19 strains isolated from clinic were with identical clone;AFLP analysis showed 19 strains isolated from clinic were with identical clone;but multiple gene cluster analysis showed 3 clones including 11 strains carried with 8 positive genes(TEM,OXA-23group,ADC,aac(3)-Ⅰ,aac(6′)-Ⅰ,ant(3″)-Ⅰ,qacE△1-sul1 and intⅠ1),6 strains with 7 positive genes(TEM,ADC,aac(3)-Ⅰ,aac(6′)-Ⅰ,ant(3″)-Ⅰ,qacE△1-sul1 and intⅠ1) and 4 strains with 6 positive genes(TEM,ADC,aac(3)-Ⅰ,ant(3″)-Ⅰ,qacE△1-sul1 and intⅠ1).CONCLUSIONS The resolving ability of multiple gene cluster analysis is higher than that of PFGE and AFLP in relatedness analysis of A.baumannii strains from hospital infection.
