The most common medical treatments are administration of antithyroid drugs and radioactive iodine, and thyroidectomy. In some patients, antithyroid therapy is limited due to serious adverse effects or failure to control disease progression. In some extreme cases,such as thyroid storm, conventional therapy alone does not yield effective and rapid improvement before the development of multiorgan failure.CASE SUMMARY This report describes a Chinese patient with severe hyperthyroidism accompanied by multiorgan failure, who was transferred to the medical intensive care unit of our hospital. The patient presented with palpitations, vomiting,diarrhea, and shortness of breath for a week. Laboratory tests showed elevation of thyroid hormones. Hepatic failure occurred with high aminotransferase levels and jaundice. Given her abnormal liver function and medication history, we could not exclude diagnosis of propylthiouracil-induced hepatic failure.Moreover, she also suffered from heart failure. Therapeutic plasma exchange(commonly known as TPE) and continuous renal replacement therapy(commonly known as CRRT) were used as life-saving therapy, which resulted in notable improvement of clinical symptoms and laboratory tests.CONCLUSION Combined TPE and CRRT are safe and effective for patients with hyperthyroidism and multiorgan failure.展开更多

Venturing beyond just the immediate repercussions, the research unearths both the overt and concealed long-term consequences that businesses encounter. This study integrates findings from various research, including quantitative reports, drawing upon real-world incidents faced by both small and large enterprises. This investigation emphasizes the profound intangible costs, such as trade name devaluation and potential damage to brand reputation, which can persist long after the breach. By collating insights from industry experts and a myriad of research, the study provides a comprehensive perspective on the profound, multi-dimensional impacts of cybersecurity incidents. The overarching aim is to underscore the often-underestimated scope and depth of these breaches, emphasizing the entire timeline post-incident and the urgent need for fortified preventative and reactive measures in the digital domain.展开更多

When continuous blood loss is found in the body, thepossibility of bleeding in the muscles and more typical sites should be considered.展开更多

文摘A continuous overcast-rainy weather(CORW) process occurred over the mid-lower reaches of the Yangtze River(MLRYR) in China from February 14 to March 9 in 2009,with a large stretch and long duration that was rarely seen in historical records.Using the empirical orthogonal function(EOF),we analyzed the geopotential height anomaly field of the NCEP-DOE Reanalysis II in the same period,and defined the stable components of extended-range(10-30 days) weather forecast(ERWF).Furthermore,we defined anomalous and climatic stable components based on the variation characteristics of the variance contribution ratio of EOF components.The climatic stable components were able to explain the impact of climatically averaged information on the ERWF,and the anomalous stable components revealed the abnormal characteristics of the continuous overcast-rainy days.Our results show that the stable components,especially the anomalous stable components,can maintain the stability for a longer time(more than 10 days) and manifest as monthly scale low-frequency variation and ultra-long-wave activities.They also behave as ultra-long waves of planetary scale with a stable and vertically coherent structure,reflect the variation of general circulation in mid-high latitudes,display the cycle of the zonal circulation and the movement and adjustment of the ultra-long waves,and are closely linked to the surface CORW process.
