Objective To analyze the correlations between pediatric intersive cave unit (PICU) nurses′job satisfaction and their perception of job characteristics. Method One hundred and thirty-six PICU nurses from a women and children′s hospital of Guangzhou participated in the study and the job diagnostic survey (JDS) and Minnesota satisfaction questionnaire short-form (MSQ20) were used to investigate the relationship between the job characteristics and job satisfaction. Results The average score on general satisfaction was (3.57 ± 0.41). The dimensions like skill variety, task integrity, feedback from job and feedback from others, had a significant positive impact on general satisfaction (all P<0.05). Conclusion Nurses generally have a relatively middle level of job satisfaction and measures should be taken to improve their job satisfaction as well as the quality of nursing.

Objective To explore the value of Toll-like receptor 2(TLR2) on the diagnosis of neonatal septicemia especially for the early diagnosis.Methods Twenty-two newborns with septicemia were divided into 2 groups according to the time of onset:early-onset group(n=12) and late-onset group(n=10).Another 14 non-infectious newborns were collected as control group.The TLR2 mRNA in peripheral blood was detected by real-time polymerase chain reaction,and mononuclear cells were isolated by the density gradient centrifuga-tion;the C reaction protein(CRP) was detected,and the co-relationship of the indexes was analyzed by Pearson correlation analysis.Results 1.The level of CRP in early-onset group were(157.89?32.96) ng?L-1,and(89.78?16.24) ng?L-1 in late-onset group,and there was significant difference between both groups(P=0.001);(6.91?1.20) ng?L-1 in control group,which was significantly lower than that in early-onset group and late-onset group(P=0.000,0.001).2.The expression of TLR2 mRNA in early-onset group and late-onset group was(57.38?10.72)?1012 copies?L-1and(32.74?4.65) ?1012 copies?L-1,which was significantly higher than that in control group[(4.12?0.68) ?1012 copies?L-1].3.CRP is positively correlated with TLR2 mRNA(C=0.972,P=0.000).Conclusions TLR2 expression is proven to be related to both the level of CRP and the stage of onset and may play a key role in the pathogenesis of neonatal septicemia.Detection for TLR2 may assist the earlier diagnose of atypical neonatal septicemia.

Objective:To observe the therapeutic effect and safety of warfarin on patients with atrial fibrillation. Methods:A total of 126 patients with atrial fibrillation from our hospital during Jun 2012-Jun 2013 were selected. According to hiding number random method,they were divided into aspirin group (n=63)and warfarin group (n=63).Coagulation function,blood lipid levels and end-point events were compared between two groups.Results:Compared with aspirin group,after treatment,there were significant reductions in levels of total cholesterol [(5.8 ±0.5)mmol/L vs.(5.2±0.7)mmol/L],triglyceride [(2.6±0.4)mmol/L vs.(2.4±0.3)mmol/L]and low density lipoprotein cholesterol [(2.7±0.5)mmol/L vs.(2.4±0.3)mmol/L],significant rise in level of high den-sity lipoprotein cholesterol [(1.1±0.2)mmol/L vs.(1.3±0.2)mmol/L],prothrombin time [(28.3±11.7)s vs. (36.9±10.4)s]and it′s international normalized ratio [(1.9±0.4)vs.(2.4±0.5)]in warfarin group,P <0.05 all.Incidence rate of endpoint events such as cerebral infarction and peripheral artery embolism etc.in warfarin group was significantly lower than that of aspirin group (3.17% vs.23.81%,P <0.01).The incidence rates of complications were 23.81% and 26.98% in warfarin group and aspirin group respectively,and they had no signifi-cant difference,P >0.05. Conclusion:For atrial fibrillation,the therapeutic effect and safety of warfarin is better than that of aspirin,is worth extending.

We explored the status of Bartonella infection in rodents and the sequence characteristics of Bartonella in Fujian Province.Rodents in Fujian Province were captured by the night trapping method during 2014-2016.Information of the captured rodents on capturing dates and geographic locations,species,gender and ages were recorded.Heart blood samples were collected,from which the fragments of ghA gene and16S-23S rRNA gene of Bartonella were amplified by polymerase chain reaction (PCR).The PCR products were sequenced and the phylogenetic tree was constructed for homology analysis by biological analysis software.Data on infection rate were analyzed with Chi-square or Fisher exact test to indicate statistical significance.Results showed that 5 917 cages were laid and 381 rodents were captured,density of rodent was 6.44％.The overall Bartonella infection rate in rodents was 12.34 ％,while infection rate in domesticated rodents was 10.61％,with 11.30 ％ in Rattus norvebicus and 10.00％ in R.flavipectus.And the infection rate in wide rodents was 13.86％,with a rate of 22.86％ in Rattus losea and 18.00％ in R.fulvescens,respectively.The infection rate was higher in wild rodents than in domesticated rodents,however,no significant difference was found.The Western Fujian and Northern Fujian region had the higher infection rates of 20.00％ and 25.33％,and no infection was found in Southern Fujian region.The statistical analysis result revealed that a significant difference in infection rate among different region and habitats,but no significant difference in infection rate between male and female rodents,or among different ages.The BLAST results revealed the species to be B.tribocorum,B.elizabethae and B.grahamii.In conclusion,Bartonella infection is found in the rodents in Fujian Province and more attention should be paid on its impact on public health in the province.

Objective To investigate the attentional bias for emotionally faces in subjects with low-trait anxiety when they are under normal or induce-fear emotion.Methods Trait anxiety inquiry(T-AI) were used to evaluate the mental health status of 480 freshman in a university,and 450 valid questionnaires were obtained.Among them,90 students were identified as low trait anxiety.Sixty students from them were randomized into 2 group(n=30) to receive a dot-probe task with emotional face as stimulus.They were asked to judge the target.The attentional bias under normal or fear-induced emotion to the emotionally faces was examined.Results Low trait anxious college students showed attentional avoidance to the negative faces when they were under normal emotion [D=(-11.09?25.40),t=-2.391,P=0.024],and the orientation was significant [OI=(-20.28?22.90),t=-4.850,P0.05].Conclusion Low trait anxious college students have attentional avoidance to negative faces because of orientation,but the avoidance will disappear when they are under fear emotion.

The diagnostic evidence on clinical diseases and theoretic basis of moving cupping therapy were ex- plored in the paper. By the observation of the local reaction, such as skin appearance and color, the affected location, duration of sickness and nature of disease were judged. Different moving cupping methods were selected for different disorders. It was discovered that the property of syndromes should be recognized by the palpation on skin and muscle in the moving cupping therapy so that the pathogenesis and treating principle could be carefully determined. The moving cupping therapy is the important component of body surface therapy. Skin reaction observation and syndrome differentiation is the essential guidance of the moving cupping therapy.

AIM: To investigate the effect of 5 - fluorouracil ( 5 - FU ) on the expression of the stem cell marker CD133 on colon cancer stem cells. METHODS:CD133 expression on several colon cancer cell lines was detected by flow cytometry. The CD133 positive cells from DLD1 cells were separated by the method of magnetic activated cell separation. Colony assay was used to measure self - renew ability and MTS assay was used to detect the sensitivity to 5 - FU after separation. After 5 - FU treatment, the change of CD133 mRNA level was measured by qPCR. RESULTS: CD133 expression on the surface of colon cacner cell lines DLD1, HT29, SW480, HCT116, Lovo, RKO was 30.20% , 82.00% , 0.34% , 91.80% , 85.30% , 0.28% respectively. DLD1 cells had two obvious populations according to CD133 expression. CD133 positive cells were separated from DLD1 cells, the positive purity was 87.21% ±5.33% and the negative purity was 84.30% ±4.65%. CD133 positive cells formed more colonies with limited dilution colony assay (46.33% ±4.44% vs 31.00% ±2.00% , P <0.05). CD133 positive cells were less sensitive to 5 - FU compared to CD133 negative cells(20% less, P <0.01). 5 - FU at concentration of 1 mg/L upregulated CD133 mRNA expression in both DLD1 and HT29 cells, the relative quantity was increased from 1 to 1.684 ±0.012(P <0.01 )and 30.702 ±0.280 to 49.379 ±0.460(P <0.01) in HT29 and DLD1, respectively. CONCLUSION: Compared to CD133 negative cells, CD133 positive cells show more ability to form colonies in vitro, and are less sensitive to 5 - FU. 5 - FU upregulats the mRNA expression of CD133, resulting in the CD133 colon cancer stem cells enrichment during 5 - FU treatment.

Objective To explore the guiding role of serum procalcitonin (PCT) in antibiotic therapy during acute exacerbation of chronic obstructive pulmonary disease (AECOPD). Methods Totally 72 patients with AECOPD were randomly divided into PCT group (n=40) and conventional therapy group(n=32).For patients in PCT group,the use of antibiotics was based on PCT serum levels,antibiotics were stopped when PCT＜0.25 μg/L,while in conventional treatment group,the use of antibiotics was based on clinical symptoms of patients.The main observation indexes included ratio of antibiotic usage,time of antibiotics use,hospital stay,clinical efficacy,aggravating cases and death cases. Results There were no significant difference in clinical efficacy between the two groups(82.5％ vs.75.8％,x2 =0.217,P=0.641),however,the ratio of antibiotics usage in PCT patients was significantly lower than conventional therapy group (47.5％ vs.71.9％,x2 =4.346,P=0.037),average time of antibiotics use and days of hospital stay were shorter in PCT treatment group than conventional therapy group [(6.84±3.27) d vs.(10.22±3.67)d,x2 =3.116,P=0.003; (11.7±5.2) d vs.(20.3±8.7) d,x2 =5.202,P=0.000].There were no difference in double infection incidence (2.5％ vs.18.8％,x2 =3.657,P=0.056),aggravating cases (3 cases vs.4 cases,x2 =0.097,P=0.756) and mortality (2.5％ vs.6.3％,x2 =0.039,P=0.843) between the two groups.Conclusions Serum PCT level may be an appropriate indicator to guide antibiotic therapy in patients with AECOPD in view of its effective decreases of excessive use of antibiotics,double infection opportunities and hospitalization time.
