Spatial statistics plays an important role in spatial epidemiology studies of echinococcosis .Spatial statistics can be used to describe the spatial distribution ,predict the prevalence ,identify disease clusters ,and analyze the influencing factors of echinococcosis .To describe spatial distribution and predict the prevalence ,we can use spatial interpolation ,empirical bayes smoothing and ellipsoidal gradient .Spatial autocorrelation always used to identify disease clusters .Moran's I value ,Getis'G val‐ue and spatial scan statistics are used to judge spatial autocorrelation .Molding plays an important role on analyzing risk factors of echinococcosis .Generalised linear mixed models and Bayesian model are always performed with both spatial factors ,such as geomorphologic features ,climatic characteristics ,vegetation index and factors which make great effect on disease transmission . To figure out the spatial distribution of echinococcosis is significant for echinococcosis control and prevention .

Objective To analyze the clinical effect and safety of cortical bone decortication combined locking plate fixation for treatment of long bone nonunion of limbs. Methods Eighty patients with long bone nonunion of limbs who were treated in the Zhongshan Hospital Affiliated to Dalian University from Jun. 2010 to Jun. 2013 were selected as our subjects and their clinical data were recorded. According to different treatment methods,the patients were divided into control group and observation group,and each group with 40 cases. Patients in observation group were treated with cortical bone decortication combined locking plate fixation, while in control group were treated with locking plate combined slotted bone graft. Clinical effects and safety of two groups were compared. Results Excellent and good rate in observation group was 100%(40/40),obviously higher than that of control group(90. 0%(36/40);χ2 =4. 21,P﹤0. 05). Bleeding amount during operation in observation group was(370. 5 ± 56. 5)ml,obviously less than that of control group((486. 5 ± 64. 5)ml;t=8. 56,P﹤0. 01). And the fracture healing time was(5. 6 ± 1. 2)months in observation group,shorter than control group((7. 2 ± 1. 5)months;t =5. 27,P ﹤0. 01). The postoperative complication occurrence rate was 5. 0%(2/40),significantly lower than control group(20. 0%(8/40);χ2 =4. 11,P ﹤0. 05). Conclusion Cortical bone decortication combined locking plate fixation for treatment of long bone nonunion of limbs is safe and effective,and it can reduce operation injury and accelerate postoperative healing of fracture.
