RESUMO
Objective To study the prevalence of tick bites and relative factors of outpatients with fever from health care fa?cilities in Tengchong County. Methods From July to August,2014,the outpatients with fever in five health care facilities namely Tengchong Center for Disease Control and Prevention,Hehua Health Center,Jietou Health Center,Qushi Health Cen?ter and Xinhua Health Center were investigated by questionnaires. The factors related to tick bites were explored with the univari?ate analysis and multiple regression models. Results Totally 884 effect questionnaires were acquired. Among the 884 partici?pants,85(9.6%)had experienced tick bites. The frequency of tick bites was associated with locations,gender,age group,own?ership of cattle,working at foreign country,firewood cutting and lumbering in the forest(all P<0.05). The multiple regression revealed that the male and people raising cattle,working at foreign country,engaging in firewood cutting and lumbering in the forest had a more risk for tick bites. Conclusions Tick bites are common in the residents of Tengchong County. The risk of be?ing bitten varies in different populations. The local health departments should promote health education in the high?risk popula?tion to reduce the risk of infecting tick?borne diseases.
RESUMO
Objective To analyze the malaria epidemiological characteristics in Tengchong City from 2010 to 2015,so as to provide the evidence for adjusting and formulating measures in the elimination stage. Methods The malaria data were collected and analyzed by using Microsoft Excel 2010 in Tengchong City from 2010 to 2015. Results There were 1 408 malaria cases re?ported in Tengchong City from 2010 to 2015,including 1 091 cases of Plasmodium vivax infection,256 cases of P. falciparum infection,5 cases of P. malariae infection,1 case of P. ovale infection,1 case of mixed infections,and 54 unclassified cases. Totally 1 390 imported cases were recorded and 98.06%of them(1 363/1 390)were imported from Myanmar. Most of the pa?tients(n=908)were aged from 21 to 40 years,and the male to female ratio was 11.03∶1. The highest?risk populations were farmers and migrant workers. The most cases were observed in April and June,and at that time,most of the floating workers re?turned. Conclusion Imported malaria is severe in Tengchong City,and there is a great challenge to malaria elimination.
RESUMO
Objective To evaluate the clinical effects and complications of non - phacoemulsification small incision extracapsular cataract extraction(ECCE) and intraocular lens implantation to treat cataract. Methods Through 5.5 -7mm scleral tunnel incisions at 12:00, 212 cases (231 eyes) of cataracts were treated with intraocular lens implantation after continuous circular capsulorhexis and extraction of lens nucleus. Results One week postoperatively, the visual acuity was ≥0.5 in 184 eyes(79.65% ) ; one month postoperatively, the visual acuity was ≥0.5 in 202 eyes(87.45% ). The main complications were corneal edema, anterior chamber inflammation and posterior capsular rupture etc. Conclusion Nnon - phacoemulsification small incision ECCE and intraocular lens implantation is simple and has satisfied effects to treat cataract.
RESUMO
Total DNA of B. amyloliquefaciens and S. aureus were isolated and cut partially with Hind Ⅲ Separately, The genes for barnase and for staphylococcal nucl ease were obtained by PCR and cloned into pGEM7Z-f(+), The sequencing show that the n ucleotide (nt) sequence of the barnase is 99.3% homologous with the previously determimed sequence and the deduced animo acid (an)sequence found to correspond precisely to the previously determined sequence; the nucleotide (nt) sequence of the staphylococcal nuclease is 99.1% homologous with the previously determined sequence and the deduced amino acid (an) sequence 99.3% homologous with the previously determinded sequence.These have built basis of making use of special expression or activation of nuclease to produce the male sterility plant by plant gene engineering and to explore new antiviral strategy.
