Investigation and sequence analysis on Bartonella infection in rodents in Fujian Province, China / 中国人兽共患病学报

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.

Peri-operative care for patients undergoing nephroureterectomy with transvaginal NOTES-assisted hybrid endoscopy / 中国实用护理杂志

Objective To explore the measure of the peri-operative care in patients undergoing nephroureterectomy with transvaginal NOTES-assisted hybrid endoscopy.Methods Nursing measures and the effect of 3 patients who underwent transvaginal NOTES-assisted hybrid endoscopy in nephroureterectomy were retrospectively analyzed.Results All procedures were successfully completed.There were no intraoperative or postoperative complications.All patients were cured and discharged.Conclusions For the patients receiving transvnginal NOTES-assisted hybrid endoscopy in nephroureterectomy,good psychological care,adequate preoperative preparation,postoperative care,and health education can reduce postoperative complications and play an important role in the success of the operation.

DNA Amplification of Plasmodium vivax Parasites from Giemsa-stained Blood Smears / 中国寄生虫学与寄生虫病杂志

Objective To develop methods of extracting DNA from malaria parasites on Giemsa-stained blood smears. Methods Improved Na2HPO4 method and Chelex-100 ion-exchange technique were used to extract DNA from Giemsa-stained or unstained blood smears. Nested PCR was employed for amplification and identification of allelotypes in the Plasmodium vivax merozoite surface protein-1(PvMSP-1). Results Target DNA bands appeared in all samples of unstained thick blood smears, while no DNA bands were visible in the fixed and stained thin smears. Both methods identified PvMSP-1 alleles from smears with parasitemia of ≥0.01%. Conclusion It is feasible to identify PvMSP-1 alleles from Giemsa-stained blood smear.
