ABSTRACT
Objective To study the effect of schistosomiasis transmission interruption model based on intensive agriculture in hilly endemic areas,so as to provide the reference for the similar endemic areas. Methods Based on the development of in-tensive agriculture in Guanghan City,a comprehensive demonstration area of schistosomiasis control with measures such as new rural construction,hardening ditches,the adjustment of industrial structure and water remediation measures was constructed. Ji-nhua,Shiguan and Hongyan villages were chosen as the evaluation sites to comparatively analyze the indexes of intensive agri-culture and schistosomiasis control effects. Results Compared with the demonstration area before construction,in 2014,the harden rates of ditches and village roads were increased by 49.57％and 39.33％respectively;and the proportion of agricultural machinery increased by 25％. The positive rate of serological tests of schistosomiasis was decreased by 81.74％. The Oncomela-nia hupensis snail area was decreased from 2.44 hm2(2007)to 0(2014). The awareness rate of schistosomiasis control knowl-edge and correct behavior rate of the residents were increased from 51.28％ and 90.85％ to 91.29％ and 97.69％ respectively. The experience of the demonstration area ensured the entire Guanghan District achieved the schistosomiasis transmission inter-ruption criterion at the end of 2014. Conclusions The schistosomiasis control model of intensive agriculture combined with oth-er comprehensive measures has a good effect on interrupting the endemic of schistosomiasis,and it can realize the sustainable development of the agricultural economy and schistosomiasis control.
ABSTRACT
Objective To compare the clinical efficacy of different surgical treatment on cholesteatoma otitis media and analy‐sis its differences .Methods Totally 100 cases of patients with cholesteatoma otitis media in hospital were divided into two groups , 50 cacse in each group ,the control group used open mastoidectomy for treatment ,the experimental group used complete bi‐style mastoidectomy ,and the postoperative clinical efficacy were observed .Results The experimental group patients after radical mas‐toidectomy complete bi‐style treatment ,air conduction hearing threshold (26 .89 ± 7 .23)dBHL and gas bone conduction (12 .54 ± 3 .78)dBHL were significantly lower than after open radical mastoidectomy treatment of patients in the control group (41 .38 ± 10 .56)dBHL and gas bone conduction (22 .57 ± 5 .96)dBHL(P<0 .05);after different surgical treatment ,the cholesteatoma otitis media total efficiency (92 .00% ) of experimental group was significantly higher than control group (64 .00% ) ( P< 0 .05 ) . Conclusion The complete bi‐style mastoidectomy is the treatment of cholesteatoma otitis media ,which can effectively repair dam‐aged eardrum ,restore patient hearing to the maximum extent ,help to restore patient′s disease and improve the quality of life of pa‐tients .
