Regional distribution and resource allocation of intraocular lens diopter in cataracts on Lifeline Express / 眼科新进展

Objective To investigate the better medical resource allocation scheme by analyzing the overall situation and regional characteristics of intraocular lens diopter in cataract patients on Lifeline Express.Methods The total of 27 663 patients data from seven administrative regions of China on cataract surgery in China Lifeline Express from 2014 to 2016 were collected.All diopter values of IOL were recorded to grasp the overall distribution of IOL diopter in cataract patients,and the distributive difference among administrative regions was analyzed.Results The distribution of IOL diopter in 27 663 cataract patients presented a skewed trend,with peak value in 21-＜22 D.The greater frequency of IOL diopter was mainly concentrated in 19-＜24 D,accounting for 72.48％ of the total.The IOL diopter peak was present in 22-＜ 23 D in Northeast China,North China,Central China,East China,and the overall waveform offset to a large degree direction.The IOL diopter peak was present in 21-＜ 22 D in Northwest,Southwest,South China,and the overall waveform showed the trend of small degree direction.The occurrence frequency of IOL with diopter ＜ 10 D was significantly more obvious in Northwest,Northeast China,North China and East China.At the same time,the occurrence frequency of IOL with diopter ≥25 D was significantly more obvious in Central China,Northeast China,East China,North China.Conclusion The IOL diopter values of cataract patients in different administrative regions present a skewed distribution and there are subtle differences between different regions.The results can provide the basis for resource allocation for large scale cataract surgery in each area.

Study of realgar induced apoptosis of eosinophils from bronchoalveolar lavage fluid in asthmatic guinea pigs / 中国临床药理学与治疗学

AIM: To observe the realgar induced the apoptosis of eosinophils from bronchoalveolar lavage fluid in asthmatic guinea pigs and investigate the mechanism that realgar treated asthma.METHODS: The morphology of apoptosis of eosinophils was observed by Giemsa staining and electron microscope.The rate of apoptosis of eosinophils was assayed by the flow cytometry.RESULTS: The characteristic changes of the apoptosis in both light microscope and electron microscope were shown after 6 hours treatment of realgar.Flow cytometry showed that the rate of apoptosis of the eosinophils was increased with both increasing realgar concentration and prolonging realgar action time to the cells.CONCLUSION: Realgar promotes the apoptosis of eosinophils from bronchoalveolar lavage fluid in asthmatic guinea pig.Realgar induced the apoptosis of eosinophils is one of the causeses for asthmatic treatment.
