Ltd. Qingdao Innovation and Development Base of Harbin Engineering University

In contrast to the Pacific and Atlantic Oceans, the Indian Ocean has lacked in-situ observations of wind profiles over open sea areas for decades. In 2021, a shipborne coherent Doppler lidar（CDL） was used to observe in-situ wind profiles in the eastern tropical Indian Ocean. This equipment successfully captured low-level jets（LLJs） in the region, and their characteristics were thoroughly analyzed. Results reveal that the observed wind speed of LLJs in the eastern Indian Ocean ranges from 6-1m s-1to 10 m s during the boreal winter and spring seasons, showing a height range of 0.6 to 1 km and two peak times at 0800 and 2000 UTC. This wind shear is weaker than that in land or offshore areas, ranging from 01 s-1to 0.006 s-1. Moreover, the accuracy of the CDL data is compared to that of ERA5 data in the study area. The results indicate that the zonal wind from ERA5 data significantly deviated from the CDL measurement data, and the overall ERA5 data are substantially weaker than the in-situ observations. Notably, ERA5 underestimates northwestward LLJs.

目的观察地诺孕素联合醋酸亮丙瑞林缓释微球应用于卵巢子宫内膜异位囊肿(EMA)术后治疗的临床效果。方法选取2020年1月—2023年12月福建中医药大学附属人民医院收治的EMA手术治疗患者80例为研究对象。采用抽签法,按1∶1的配比分为联合组和亮丙瑞林组,各40例。亮丙瑞林组予醋酸亮丙瑞林缓释微球治疗,联合组在亮丙瑞林组基础上联合地诺孕素治疗。比较2组疗效、卵巢储备功能[血清抗苗勒氏管激素(AMH)、卵巢窦状卵泡数量(AFC)]、肿瘤标志物[糖类抗原125(CA125)、糖类抗原199(CA199)]、术后停经恢复情况、生活质量[世界卫生组织生存质量量表(WHOQOL-100)评分]及不良反应。结果联合组总有效率(95.00%)高于亮丙瑞林组(77.50%)(χ^(2)=5.165,P=0.023)。与治疗前比较,治疗后,2组AMH水平及AFC降低或减少,CA125、CA199水平下降,WHOQOL-100评分升高,且联合组变化程度大于亮丙瑞林组(P<0.05或P<0.01);术后2个月,联合组月经恢复率为95.83%(23/24),高于亮丙瑞林组的69.57%(16/23)(χ^(2)=5.738,P=0.017)。联合组与亮丙瑞林组不良反应总发生率比较无统计学差异(5.00%vs.2.50%,P=1.000)。结论地诺孕素联合醋酸亮丙瑞林缓释微球进行EMA患者的术后治疗,取得良好效果,有助于促进卵巢储备功能改善,降低血清肿瘤标志物水平,促使月经恢复,且具有较高安全性,可提升患者生活质量。
