ABSTRACT
Objective To investigate the awareness of malaria-related knowledge, the use of mosquito nets and their influencing factors among residents in Banlao Township, Cangyuan County, Yunnan Province.. Methods In August 2020, 19 settlement sites in Banlao Township, Cangyuan County, Lincang City, Yunnan Province were selected as study areas, and permanent residents at ages of 10 years and older were enrolled for a questionnaire survey, including residents’ demographics, family economic status, malaria control knowledge and use of mosquito nets. In addition, the factors affecting the use of mosquito nets in the night prior to the survey were identified using multivariate logistic regression analysis. Results A total of 320 questionnaires were allocated, and all were recovered (a 100% recovery rate). There were 316 valid questionnaires, with an effective recovery rate of 98.75%. The 316 respondents included 152 men and 164 women and 250 Chinese respondents and 66 foreign respondents. The awareness of clinical syndromes of malaria was significantly higher among Chinese residents (71.60%) than among foreign residents (50.00%) (χ2 = 11.03, P < 0.01), and the proportions of Chinese and foreign residents sleeping under mosquito nets were 46.00% and 69.70% on the night prior to the survey, respectively (χ2 = 11.73, P < 0.01). Multivariate logistic regression analysis identified ethnicity group and type of residence as factors affecting the use of mosquito nets in the night prior to the survey. Conclusions The awareness of malaria control knowledge, the coverage and the use of mosquito nets were low among residents in Banlao Township, Cangyuan County, Yunnan Province. Targeted health education is recommended to improve the awareness of malaria control knowledge and self-protection ability. In addition, improving the allocation of long-lasting mosquito nets and health education pertaining to their uses and increasing the proportion of using mosquito nets correctly is needed to prevent re-establishment of imported malaria.
ABSTRACT
Objective To compare the results of laparoscope and laparotomy total mesorectal excision(TME)with anal sphincter preservation in the treatment of low rectal cancer.Methods From January 2006 to June 2008,106 patients with low rectal cancer which the distance from the lowest margin of tumor to the dentate line ranged from 3.0 to 7.0 cm underwent TME with anal sphincter preservation.Among them,51 patients received laparoscope operation(laparoscope group)and the other 55 patients received laparotomy(laparotomy group)according to their wills.Results Two groups had no serious complications and death case.after surgery,the rate of sphincter preservation was 100%.Blood loss was(20.2±5.7)ml inlaparoscope group,which was significantly less than that in laparotomy group(P ＜ 0.01),aerofluxus,time to eat half-flow food and hospital stay were(2.4±0.6),(5.4±0.6)and(9.2±3.2)days respectively,which were significantly shorter than those in laparotomy group(P ＜ 0.01 or ＜ 0.05).Bowel function was back to normal in 35 patients of laparoscope group(68.6%)and 39 patients of laparotomy group(70.9%)within 1 month.All patients were followed-up from 6 to 36 months,there were no recurrence in situ local recurrence and mortality in the both groups.Conclusion Laparoscope TME with anal sphincter preservation can be achieved the same effect of oncological clearance,it is feasible and it is a minimal invasive and perspective technique with the benefits of much less blood loss during operation,higher rate of sphincter preservation,earlier return of bowel function and shorter hospitalization.
