Objective To understand the epidemic features of bacillary dysentery in Yongcheng district,from 2008 to 2012,in order to provide scientific basis for formulating control and prevention measures. Methods The bacillary dysentery cases that reported by health institutions in Yongcheng dis-trict through the national disease surveillance system,from 2008 to 2012,were analyzed descriptively. Results Bacillary dysentery incidence ascended with years from 2008 to 2012,the average of dysentery incidence rate was 17. 29 / 100,000. No death case was reported. The ratio of male to female was 1. 36:1. The age of onset in children under the age of five,which accounted for 31. 9% of all cases. The cases of the top three are farmers,students,young dragging children,or report the number 56. 94% , 30. 41% ,7. 93% ,respectively. Bacillary dysentery incidence in 6 - 9 months had a peak,constituted by 52. 98% . Bacterial serotyping showed that 47 of 75 strains were Shiella sonnei(62. 67% ). Conclu-sions Incidence of bacillary dysentery were ascended,then effective prevention and control measures should be formulated according to incidence spectrum.

Objective To evaluate the effects of different vector mosquito control measures for malaria in Yongcheng through field tests.Methods Vector monitoring was conducted in villages using different vector prevention and control measures,where mosquitoes of anopheles were captured every ten days using 50 mosquito nets indoors in early morning and using human baits outdoors at night.Results A total of 79 anopheles mosquitoes were captured by nets in early morning,accounting for 33.33%,with other captives of 158 accounting for 66.67%.The average anopheles density was 0.18/net per capture in the control group,and 0.03,0.03,0.05 and 0.06/net per capture in the impregnated-net group,residual spraying group,impregnated-net plus larviciding group and residual spraying plus larviciding group,respectively.Albeit effective in reducing anopheles density(F=4.553,P0.01),these measures were not deemed different in the effects.The average man-biting rate was 0.10 mosquito/(person·night) in the control group,and 0.02,0.01,0.03 and 0.03 mosquito/(person·night) in the impregnated-net,residual spraying,impregnated-net plus biological larviciding and residual spraying plus larviciding groups,respectively.Though effective in reducing man-biting rates(F=5.261,P0.01),the measures were not considered different in the effects.At different monitoring sites,183 anopheles mosquitoes were captured outdoors by human baits at night,accounting for 15.69%,with other captives of 983 accounting for 84.31%.The average anopheles density was 2.48/h in the control group,and 0.76,2.12,0.24,1.08 and 0.64/h in the impregnated-net,residual spraying,biological larviciding,impregnated-net plus larviciding and residual spraying plus larviciding groups,respectively.The mosquito density in the impregnated-net,biological larviciding,impregnated-net plus larviciding and residual spraying plus larviciding groups was lower than that in the control group,and the density in the residual spraying group was higher than those in the impregnated-net,biological larviciding and residual spraying plus larviciding groups.The average man-biting rate was 12.40 mosquitoes/(person·night) in the control group,and 3.80,10.60,1.20,5.40 and 3.20 mosquitoes/(person·night) in the impregnated-net,residual spraying,biological larviciding,impregnated-net plus larviciding and residual spraying plus larviciding groups,respectively.The man-biting rates in the impregnated-net,biological larviciding,impregnated-net plus larviciding and residual spraying plus larviciding groups were lower than that in the control group,while the rate in the residual spraying group was higher than those in the impregnated net,biological larviciding and impregnated-net plus larviciding groups.The Pearson correlation analysis revealed a positive correlation between the outdoor anopheles density in October and the incidence of malaria in November(r=0.945,P0.01),and a positive correlation between the corrected man-biting rate in October and the incidence of malaria in November(r=0.927,P0.05).Conclusion The above prevention and control measures were effective in reducing both indoor and outdoor anopheles density as well as man-biting rates in Yongcheng city;however,the advantages and disadvantages of specific measure should be further studied.

急性阑尾炎是外科常见病,也是最多见的急腹症,原则上急性阑尾炎一经确诊,应尽早作阑尾切除术.目前临床上应用的方法有:传统的阑尾切除术、小切口阑尾切除及腹腔镜阑尾切除.

腹股沟疝是小儿最常见的外科疾病.其发生是因为胚胎时期形成的腹膜鞘状突闭合不全与出生后腹内压增高使未闭鞘突扩张而成.如果不做治疗,疝囊可逐渐增大,加重腹股沟管的缺损,且常发生嵌顿成为急症,甚至造成严重后果,因此一般应及早手术.
