ABSTRACT
Objective To learn the prevalence and risk factors of anorectal diseases among urban population aged 18 -80 years in Lanxi.Methods Typical sampling was adopted to select one urban area from Lanxi City.Face -to -face interviews and physical examinations were carried out to collect data during June 2015 to September 2015.Results A total of 3 327 residents were recruited,of which 2 931 were involved in both questionnaires and physical examinations.Totally, 1 554 participants were detected one or more anorectal diseases.The prevalence rate was 53.02% (standardized rate 45.61%).Hemorrhoids cases was accounted to the most,and the prevalence rate was 49.47% (standardized rate 42.41%).Male was associated lower risk of hemorrhoid (OR =0.37,95%CI:0.32 -0.44).Compared to 18 -30 age group,older age were associated with increasing risks of hemorrhoid significantly despite of 31 - age group.Results for different groups were 41 -(OR =1.66,95%CI:1.05 -2.62),51 -(OR =1.94,95%CI:1.23 -3.07),61 -(OR =1.92,95%CI:1.19 -3.09)and 71 -80 (OR =2.62,95%CI:1.57 -4.39).Only junior high school (OR =1.30,95%CI:1.01 -1.66)and senior high school (OR =1.57,95%CI:1.19 -2.07)were significantly associated with high risk of hemorrhoid.Conclusion The prevalence of anorectal diseases in Lanxi urban area is high.Gender,age and education level might be independent risk factors of hemorrhoid.Therefore,preventive strategies should vary across different population with different characteristics.
ABSTRACT
Objective To know the prevalence of anorectal disease and its influencing factors among rural residents in Lanxi city.Methods A cluster sampling method was performed,a total of 2 287 residents aged 1 8 years and over were selected. A questionnaire interview and physical examination were carried out.Results The prevalence of anorectal diseases was 64.1 5% totally,with female 73.02% and male 52.66%,respectively.Multivariate analysis showed that gender,age, marriage status,working intensity,defecation habit,family history of anorectal disease and body mass index were the influencing factors (P <0.01 ).Conclusion The prevalence of anorectal diseases was relatively high among rural residents in Lanxi city.The colonoscopy should be recommended and health education should be taken in general physical examination.
ABSTRACT
Objective To design a new correction device for elbow deformity with active orthopedic force based on Ilizarov technique, and discuss its curative effect on elbow orthotics in clinic. Methods A total of 44 patients with elbow joint dysfunction were randomly divided into treatment group (n=22) and control group (n=22), and treated with new deformity orthotic device and continuous positive motion, respectively. The functional recovery of the elbow joint for patients in two groups was evaluated after 3-month treatment. Results The range of motion (ROM) of elbow flexion-extension in treatment group was significantly larger than that in control group, and the effective rate for treatment group and control group was 90.91% and 81.82%, respectively. Conclusions The use of such correction device for elbow deformity showed good curative effect for treating elbow joint dysfunction, which is worth popularization and application in clinic．
