ABSTRACT
Objective@#To explore the management effects of health knowledge-attitude-practice education on phosphorous control in peritoneal dialysis patients with hyperphosphatemia.@*Methods@#A total of 64 peritoneal dialysis patients with hyperphosphatemia with long-term stable follow-up in the People’s Hospital of Quzhou from 2016 to 2018 were selected, and randomly divided into control and intervention groups. The groups received regular health education and health knowledge-attitude-practice education for 3 months, respectively. T-test and paired t-test were used to analyze the difference in the two groups, before and after intervention, in the score of knowledge-attitude-practice, serum phosphorus level, daily dietary phosphorous, and dosage of phosphate binder.@*Results@#Before the health education intervention,there was no significant difference between the two groups’ questionnaire score of knowledge-attitude-practice of hyperphosphatemia, serum phosphorus, intact parathyroid hormone (iPTH), daily dietary phosphorous, dosage of phosphorus binder, and weekly urea clearance index in gender, age, and other general information. After 3 months of health education, the total score, knowledge, and behavior scores were higher in both groups than before intervention, and the scores of the intervention group were significantly higher than the control group. The scores increased by 16.64, 6.15, and 9.52 points respectively in the control group, and by 26.26, 11.67, and 13.56 points respectively in the intervention group. There was no significant difference in attitudes and beliefs between the groups before and after the intervention. After the intervention, the serum phosphorus level decreased, dosage of phosphate binder increased in both groups, the daily dietary phosphorous and iPTH decreased in the intervention group. These differences were statistically significant. The serum phosphorus level of the intervention group (1.86±0.42) mmol/L was lower than the control group (1.97±0.33) mmol/L, and the daily dietary phosphorous of the intervention group (831.22±187.85) mg/d was lower than the control group (928.23±192.81) mg/d. The difference in dosage of phosphate binder and iPTH of the groups was not statistically significant.@*Conclusions@#Health knowledge-attitude-practice education in peritoneal dialysis patients with hyperphosphatemia can improve their level of knowledge-attitude-practice, and promote the reduction of serum phosphorus.
ABSTRACT
Objective@#To provide scientific evidence for the prevention and control of the hand, foot and mouth disease (HFMD), we analyzed the epidemiological characteristics and pathogen surveillance of HFMD cases which were reported in Liaoning Province from 2008 to 2017.@*Methods@#The information of cases and laboratory monitoring were collected from the HFMD reports of 2008-2017. The epidemic intensity, three distribution and pathogen composition of HFMD were analyzed by using descriptive epidemiological method .@*Results@#There were 290 339 cases reported during 2008 to 2017 and the average incidence was 66.56/100000. The peak incidence was found for June to August, The incidence of crowd was mainly in the 0-6 years old children, and the male / female incidence ratio was 1.50∶1. Among 16 498 laboratory diagnosis cases, EV-A71 positive cases were 4 974 (30.15%), CV-A16 positive cases were 5 130(31.10%), and the other enteroviruses positive cases were 6 394 (38.76%).@*Conclusions@#The overall situation of HFMD in Liaoning province showed a fluctuating downward trend from 2008 to 2017. The epidemic had obvious seasonality and population, and the pathogenic characteristics were constantly changing, Monitoring should be strengthened.
ABSTRACT
Objective @#To learn the epidemic distribution of avian influenza virus in external environments in Liaoning Province,and to provide evidence for the prevention and control of avian influenza.@*Methods @#The environmental samples were collected monthly during 2016 and 2017（including samples from emergency monitoring in June to August,2016 and March to May,2017）from live poultry markets,live poultry wholesale markets,large-scale poultry farms（households）,free-range poultry famers and poultry processing factories in Liaoning Province. Real-time polymerase chain reaction assay was used to detect nucleic acid of Influenza A as well as H5,H7 and H9 subtypes in the environmental samples. The distribution of avian influenza virus in external environments in Liaoning Province was analyzed.@*Results @#A total of 4 037 environmental samples were collected and detected from 2016 to 2017,there were 177 copies of type A avian influenza virus and the positive rate of avian influenza A virus was 4.38%. The positive rate in 2017 was 6.26%, which was higher than 2.40% in 2016（P<0.05）. H9 subtype had the highest positive rate of 3.07%;H7 subtype was first detected in 2017. The positive rates of avian influenza virus from the first to fourth quarters of a year were 8.54%,4.88%,2.17% and 1.45%,respectively. The positive rates of avian influenza virus in live poultry markets were 8.08%,the highest among different sites,and the subtypes were mainly H9. The positive rates of avian influenza virus in samples of poultry cage and poultry washing sewage were 23.47% and 15.96%. H5 and H9 subtypes were detected in all types of samples,and H7 subtypes or mixed types were detected in samples of feces,poultry cage,poultry drinking water and chopping board.@*Conclusion @#The subtypes of avian influenza virus in the environments of Liaoning Province were mostly H9 and H5,and the H7 was first detected in 2017. Live poultry markets should be the key monitoring sites,especially in winter and spring.
ABSTRACT
The epidemic characteristics and genotype of Bacillus anthracis strains in Liaoning Province ,China was analyze in this study .Six Bacillus anthracis strains from 2001 to 2011 were studied with multiple‐locus variable‐number tandem repeat analysis (MLVA) .BioNumerics4 .0 software was used to analyze the DNA fingerprint of statistics ,and cluster analysis results were obtained .Clustering analysis found that the 6 strains could be divided into two genotypes .For anthrax outbreaks ,the ge‐netic markers of multiple‐locus variable‐number tandem repeat were highly similar .It's suggested that MLVA is quite useful for investigation of strain relatedness in regions of outbreaks .
ABSTRACT
The aim of this study is to develop a rapid and accurately species typing method for Brucella isolates by using High Resolution Melting (HRM ) analysis .Six pairs of primers were used according to the reference for the sequence of pur‐pose gene .Nineteen biotypes of six species Brucella standard strains were identified by PCR‐HRM analysis and this analysis was used to detect the 35 clinical isolates .Results showed Brucella amplified specific melting curves were different from con‐trasted strains with primer Bspp .The six species Brucella standard strains have own characteristic curve shape from each oth‐ers by PCR‐HRM analysis with five pairs of primers .Thirty‐five clinical isolates of Brucella have entirely consistent with PCR‐HRM curve shape with Brucella melitensis standard strains .So ,PCR‐HRM analysis methods can accurately identify Brucella strains ,especially clinical isolated Brucella melitensis ,and may be used in clinical microbiology laboratories .
