ABSTRACT
We investigated the carrying status of the virulence genes of Salmonella from different sources in Shijiazhuang City,China,to provide the basic data for the further risk assessment of Salmonella.A total of 186 isolates of Salmonella from different sources were collected and identified serotypes in the area of Shijiazhuang from 2011 to 2016.PCR was performed for eight virulence genes (invA,sopE,agfA,spvR,hilA,stn,pefA,shdA).These Salmonella bacteria were detected in 13 kinds of serotypes.Enteritidis is a significant advantage of the group.The above 8 virulence genes were analyzed,and the virulence genes hilA,stn and invA were the most frequently carried,their respective carrying rate were 90.3％ (168/186),86.6％ (161/186) and 82.8％ (154/186) respectively.We found the virulence genes of Salmonella from different sources were different.It is necessary to take measures to strengthen the food hygiene supervision and prevention and control of the storage and sale of raw poultry stalls in the morning market in Shijiazhuang area.
ABSTRACT
Objective To investigate the differences and characteristics of virulence genes carried by Salmonella enteritidis from different sources in Shijiazhuang City.Methods One hundred and twenty-four strains of Salmonella enteritidis isolated from morning markets of raw and poultry stalls,slaughterhouses and food poisoning specimens in Shijiazhuang area were collected.Eight virulence genes (invA,sopE,agfA,spvR,hilA,stn,pefA,shdA) were detected by polymerase chain reaction (PCR).Results Salmonella enteritidis might have different virulence gene profiles.The above eight virulence genes were detected in different strains.The carrying rate of virulence genes invA,sopE,stn,hilA,spvR and pefA in the food poisoning strains was higher than 94％.There was no difference in the carrying rate of 8 virulence gene between the morning raw poultry stalls isolates and the patient strains,but was different with the slaughterhouse strains.Conclusion There were more risks of food poisoning caused by Salmonella enteritidis from morning markets,and the hygiene supervision should be strengthened to prevent and control foodborne disease.
ABSTRACT
Objective To investigate the relationship between plasma homocysteine on admission and the outcome at discharge of acute ischemic stroke.Methods A non-concurrent cohort study was performed and a total of 1 3 1 9 patients with acute is-chemic stroke were continuously included in this study.According to tertile range of plasma homocysteine,patients were di-vided into three group.Logistic regression analysis was used to assess the independent association between plasma homocys-teine on admission and poor outcome at discharge of acute ischemic stroke.Results The difference of plasma homocysteine on admission between the poor outcome and those with good outcome had statistical significance (P<0.000 1).Without the adj ustment of multiple factors,when comparing to the first group,the second and third tertile seemed to have a tendency of increasing the risk of poor outcome at discharge,the OR (95%CI)was 2.111 (1.297~3.437,P<0.05),2.113 (1.361~3.279,P<0.05).After adjustment for multivariate,the second and third tertile also seemed to have a tendency of increasing the risk of poor outcome at discharge,the OR (95%CI)was 1.876 (1.160~3.036,P<0.05),2.396 (1.414~4.062,P<0.05).Conclusion The current study indicated that higher plasma homocysteine level was an independent risk factor for poor outcome at discharge in ischemic stroke patients.It would increase the risk of the outcome at discharge in patients with acute ischemic stroke,and suggests that there is a dose-response relationship between plasma homocysteine level on admis-sion and the poor outcome at discharge.
ABSTRACT
Objective To explore the adverse effects of recurrence of acute ischemic stroke at discharge.Methods Continuously including 3 440 acute ischemic stroke patients from June 1,2009 to May 31, 2012 in Department of Neurology of the People's Hospital of Xinganmeng of Inner Mongoha Autonomous Region were esearch objects.Poor outcome was defined as the occurrence of disability or death at discharge.Disability was defined as the Modified Rankin ' s Scale (MRs), when MRs was 3 or more.Binary logistic regression was used to analysis the risk factors ,calculated the odds ratios(OR) and 95％ confidence interval (95％CI).Results A total of 359 (10.44％) patients occurred poor outcomes, of whom 136 (37.88％) patients occurred the recurrence of ischemic stroke.Multiple logistic regression analysis showed that age (OR=1.24,95％CI 1.09-1.41), body temperature (OR =1.92,95 ％ CI 1.43-2.57), hypertension (OR =1.73,95 ％ CI 1.33-2.24), high blood sugar (OR=1.67,95％CI 1.26-2.20) ,glycerin trilaurate(OR=0.41,95％CI0.27-0.62) ,smoking (OR =1.37,95％CI 1.01-1.85) and recmrrence(OR=1.49,95％CI 1.15-1.95) were independent risk factors of poor outcome at discharge.The recurrence of acute ischemic stroke can increase the risk of the occurrence of poor outcome at discharge up to 49％.Conclusion Recurrence is an independent risk factor for the poor outcome of acute ischemic stroke, we should focus on secondary prevention of stroke patients at the clinical work and health education to reduce the recurrence of ischemic stroke.
ABSTRACT
Objective To examine the association between uric acid (UA)levels of patients with acute ischemic stroke at ad-mission and discharged outcome.Methods The acute ischemic stroke patients of Xinganmeng People’s Hospital in Inner Mongolia,from June 1,2009 to May 31,2012 were continuity included in the present study,the included analysis sample size were 3 440 cases.Poor discharged outcome was defined as the occurrence of disability or death.With reference to the Modi-fied Rankin's Scale (MRs)Stroke Scale,Scores were recorded in the questionnaires,score of 3 or more (MRs≥3)was de-fined as disability.The patients were all grouped by P20,P60,P90 of UA,binary logistic regression were used in studying of risk factors,calculated the odds ratios (Odds ratio,OR)and 95% confidence interval (95% Confident interval,95%CI).All tests were two-sided test and a significance level of 0.05.Results A total of 359 people occurred poor outcomes in the stud-y,accounting for 10.44%.Univariate logistic regression analysis of poor outcome occurred showed that relative to the lowest group(P20,UA≤222.6 mmol/L),the second and third group (UA:222.7 ~ 310.9 mmol/L and 311.0~419.7 mmol/L) OR (95% CI)were:0.70(0.53~0.91)(P <0.05)and 0.66(0.49~0.88)(P <0.05).After adjusted age,body tempera-ture,high blood pressure,hyperglycemia,history of stroke,high triglycerides,high LDL-C and smoking,relative to the low-est level group,the second and third group occurred poor outcoming OR (95% CI)were:0.70(0.53~0.93)(P <0.05)and 0.66(0.48~0.90)(P <0.05).Conclusion Higher levels of uric acid levels in patients with acute ischemic stroke may inde-pendently related with occurred poor discharged outcome.
ABSTRACT
Objective To investigate the level of compassion fatigue and its influencing factors among ICU nurses.Methods A total of 1 530 ICU nurses in 2 third-grade hospitals in Wuwei city were investigated by using convenience sampling method,general questionnaire and Paramedics Compassion Fatigue Scale Questionnaire.Results The average original score of 7 items of compassion satisfaction was (2.73±0.39),and the item of emotional indifference got the highest score (3.31±0.26),the item of physical and mental exhaustion got the lowest score (2.13±0.22).It could be show that the age,intrinsic satisfaction,extrinsic satisfaction were the main influencing factors of compassion fatigue after multiple regression analysis.Conclusions To give regular psychological intervention and sharing the experience of nurses in different departments were an effective way to relieve nurses compassion fatigue and to reduce the nurses' psychological pressure.
