ABSTRACT
Objective To explore the relationship between embryo damage and anxiety,depression and life events during pregnancy. Methods A case control study was carried out. 192 women diagnosed with embryo damage were selected as the case group,and 192 normal pregnant women or normal parturition within 7 days were selected as the control group from March to June,2014.All cases were from two 3-A-grade general hospitals of Jining. Self-rating anxiety scale ( SAS ) , center for epidemiological survey, depression scale( CES-D) and life events scale for pregnant women( LESPW) were used to evaluate the anxiety,depres-sion and life events of the two groups,so as to analyze the association between these factors and embryo dam-age. Results Multiple non-conditional logistic regression analysis showed that anxiety ( β=0. 409, OR=1.050,95%CI =1.003-1.009) ,depression( β=0.085, OR=1.088,95%CI =1.035-1.145) ,life events dur-ing pregnancy( β=0.003, OR=1.003,95%CI =1.001-1.005) were the risk factors of embryo damage,while education ( β=-0.749, OR=0.452,95%CI=0.298-0.685) ,pre pregnancy health status ( β=-1.366, OR=0.255,95%CI =0.098-0.655) and taking the initiative to acquire knowledge of eugenics ( β=-0.884, OR=0.413,95%CI =0.203-0.840) were the protective factors of embryo damage. Conclusion Anxiety,depres-sion and life events during pregnancy are related to the occurrence of embryo damage. High degree of educa-tion,pre pregnancy in good health and taking the initiative to acquire eugenics knowledge can reduce the oc-currence of embryo damage.
ABSTRACT
Objective Based on the educational concept of competency based education,this paper analyzed the present situation and problems of nursing occupational protection education and occupational protection in china,and explored the necessity of setting up the nursing occupational toxicology and nursing occupational protection in the nursing colleges.Methods The whole tentative plan was presented through the analysis of the course description,teaching method,curriculum content and objectives,curriculum evaluation of nursing occupational toxicology and nursing occupational protection in colleges.Results Students will be able to really aware of the health dangers of various toxic and harmful substances,to set up the correct ideas of occupational protection,to actively taken effective protective measures,to avoid personal injury accidents by studying in this program.Conclusions A course of occupational toxicology study and nursing occupational protection in nursing colleges is suggested to enhance the students' ability of occupational protection.It is imperative for nursing students to complete the degree program.
ABSTRACT
OBJECTIVE To investigate the 16S rRNA methylases gene and AMEs of 30 strains multi-resistant Pseudomonas aeruginosa isolated from clinic work in our hospital.METHODS Collected 50 P.aeruginosa strains from two hospitals(30 strains of multi-resistant P.aeruginosa from Yantai,Shandong,20 strains of pan-drug resistant P.aeruginosa from Jiangsu),and analyzed 6 kinds of 16S rRNA methylases(armA,rmtA,rmtB,rmtC,rmtD and npmA) and 6 kinds of AMEs gene aac(3)-Ⅰ,aac(3)-Ⅱ,aac(6′)-Ⅰb,aac(6′)-Ⅱ,aac(3″)-Ⅰ,and aac(2″)-Ⅰ by PCR and sequence analysis.RESULTS Among 30 strains of multi-resistant P.aeruginosa from Yantai,the positive rate of 4 kinds of genes aac(3)-Ⅱ,aac(6′)-Ⅱ,aac(3″)-Ⅰ,and aac(2″)-Ⅰ was 20%(6/30),46.7%(14/30),36.7%(11/30) and 3.3%(1/30).The other 8 kinds genes were all negative.The total positive rate of AMEs gene was 46.7%(14/30).In 20 strains of pan-drug resistant P.aeruginosa,the positive rate of 6 kinds of genes rmtB,aac(3)-Ⅱ,aac(6′)-Ⅰb,aac(6′)-Ⅱ,aac(3″)-Ⅰ,and aac(2″)-Ⅰ was 55%(11/20),60%(12/20),35%(7/20),60%(12/20),50%(10/20) and 45%(9/20).The other 6 kinds genes were all negative.The total positive rate of AMEs gene was 95%(19/20).CONCLUSIONS It is the first report that 16S rRNA methylases gene is existed in P.aeruginosa;there is very high positive rate of AMEs genotypes in P.aeruginosa;there are differences in gene existing among two hospitals.
ABSTRACT
OBJECTIVE To investigate the antimicrobial susceptibility of Streptococcus pneumoniae isolated in Yantai and their mechanisms of resistance to macrolides.METHODS Antimicrobial susceptibility of S.pneumoniae was determined by agar dilution method.Phenotypes of macrolide-resistant S.pneumoniae were determined using double disk test with erythromycin and clindamycin disks.ermB And mefE genes were amplified by PCR.RESULTS Among 42 strains of S.pneumoniae,65.0% were intermediate to and no strain was resistant to penicillin.The resistance rates to erythromycin and clindamycin were 93.0%,respectively.Of 41 erythromycin resistantstrains,93.0% were constitutive resistant.ermB Was detected in 40 strains and mefE in 1 strain,both ermB and mefE genes were found in 9 strains.CONCLUSIONS The resistance rate of S.pneumoniae to penicillin is high in Yantai area,the resistance rates to erythromycin and clindamycin are very high.Target modification by ermB methylase is the predominant mechanism in macrolide-resistant S.pneumoniae in Yantai.
ABSTRACT
OBJECTIVE To provide laboratory evidence for the prevention and control of coagulase negative staphylococcus(CNS),and study the distribution and drug resistance of CNS in our hospital.METHODS CNS of inpatients from Oct 2005 to Dec 2007 was isolated and identified with ATB Expression microbe identification and drug sensitivity system.RESULTS A total of 354 strains of CNS were isolated,from the main samples of secretion,sputum,blood and cerebrospinal fluld.The isolation rate from departments of pediatrics,ICU,orthopedics and neurology were 9.90%,9.30%,9.00% and 5.60%,respectively.CONCLUSIONS CNS is playing a significant role in nosocomial infection.The drug resistance of CNS is very serious.To pevent nosocomial infection,it is critically important to monitor the antimicriobial resistance of CNS and use autibiotics more rationally.
