谷户钩(TMH)内路小梁切开术作为微创青光眼手术(MIGS)中的一种,可将小梁网切开120°~240°,减少小梁网(Schlemm管内壁)的房水流出阻力,从而降低眼压。该手术不破坏结膜,对眼表的侵袭性小,安全性高,无滤过泡相关的并发症;与其它M... 谷户钩(TMH)内路小梁切开术作为微创青光眼手术(MIGS)中的一种,可将小梁网切开120°~240°,减少小梁网(Schlemm管内壁)的房水流出阻力,从而降低眼压。该手术不破坏结膜,对眼表的侵袭性小,安全性高,无滤过泡相关的并发症;与其它MIGS相比,该手术使用的谷户钩尖端较小,更方便操作,且可重复使用、不需要昂贵的设备,具有较高经济效益。本文对谷户钩内路小梁切开术治疗青光眼的原理、手术步骤、有效性及安全性等进行综述。 展开更多

Methods of participatory rural appraisal and mathematical statistics were adopted to study livelihood diversification, livelihood strategy and farmland use of the four types of farmers in Xinping County of Yuanjiang dry-hot valley with field survey data. The results showed as follows: firstly, as farmers are transforming from pure agriculture to non-agriculture, their agricultural livelihood diversification index will decrease, while non-agricultural livelihood diversification index will increase. In term of livelihood activities, pure agricultural farmers are exclusively engaged in agricultural activities, agricultural-dominant and non-agricultural-dominant farmers are engaged in both agricultural and non-agricultural ones, while non-agricultural farmers are basically engaged in off-farm activities. Secondly, as for crops planted, pure agricultural and agricultural-dominant farmers tend to choose those crops with more investment,shorter growth period and higher value, meanwhile non-agricultural-dominant farmers tend to choose crops with less investment, simpler management and longer growth period. Thirdly, to cope with current problems in farming, pure agricultural farmers will adopt measures such as changing planting structure, maintaining or expanding planting scale, increasing planting investment and renting in more land to promote the development of farming; agriculture-dominant farmers will adopt measures such as changing planting structure, reducing planting scale, maintaining planting investment, renting in and taking back the leased land as well as engaging in non-agricultural activities to overcome the difficulties faced; while non-agricultural-dominant farmers will adopt measures such as reducing both planting scale and investment,changing planting structure and engaging in farmland transfer as well as various offfarm activities to avoid livelihood risks. 展开更多
