文章利用基于布里渊散射原理的BOTDR（布里渊光时域反射仪）技术研究了OPGW（光纤复合架空地线）光缆内部光纤在不同环境温度条件下的布里渊频移变化特性。研究表明,同一光缆内不同光纤的布里渊散射频移的温度系数与基础频移具有微小差异,且日照区与非日照区的温度系数有比较固定的差异。

Objective To understand the status quo of infectious disease reports automatically exchanged by secondary and above medical institutions in Sichuan province based on regional platform, and provide basis for improving the work on automatic exchange of infectious disease information reports in the next step. Methods Check and calculate the success rates of exchange and rough exchange through the system, the use of the infectious disease reporting management related systems was investigated by questionnaire survey, T - test and chi - square test were used for comparison between groups, and spearman correlation analysis was used for correlation. Results From July to September 2023, the exchange success rate in 68 medical institutions was 92. 67%, and the success rate of crude exchange reached 95. 87%. Compared with other level medical institutions, municipal medical institutions had higher success rate of exchange and crude exchange, and longer time interval to realize automatic exchange. The exchange success rate was positively correlated with the time interval to realize automatic exchange (r = 0. 44, P < 0. 001) and the crude exchange success rate (r = 0. 51, P < 0. 001). More than 90% of the institutions had HIS, LIS, PACS. 77. 94% of the institutions could automatically generate the report card, more than 80% had the report card management and information statistics query functions. 73. 53% realized the automatic early warning of infectious disease report card, and 25% of the institutions reported the card forcibly after the early warning. 88. 24% felt that the workload of infectious disease report was reduced after automatic exchange. Conclusion The success rate of automatic exchange and the success rate of crude exchange in medical institutions were higher overall, municipal medical institutions were higher than other levels of medical institutions. The construction rate of basic information system in medical institutions was high, but the basic functions of automatic exchange were not perfect. Automatic exchange improves the efficiency of reporting to some extent, but it still could not completely replace manual reporting. [ABSTRACT FROM AUTHOR]

Aldosterone is a kind of steroid hormone produced by the zona glomerulosa (ZG) cells of the adrenal cortex which plays a crucial regulatory role in fluid-electrolyte balance and blood pressure stability. Aldosterone biosynthesis is a calcium-dependent process, and ion channels play a key role in this process. Primary aldosteronism is closely related to mutations in ion channels. Recent studies have highlighted an intriguing relationship between the unique rosette structure of ZG cells and their electrical excitability. Elucidating the connection between rosettes and ZG cell electrical excitability as well as aldosterone secretion leads to a deeper understanding of the mechanisms regulating aldosterone secretion and may provide new insights into the pathogenesis of primary aldosteronism.
