英國研究團隊測試一種透過耳部刺激神經系統的小型裝置,發現對於高血壓程度較嚴重且藥物控制不佳的患者,該裝置可能有助於降低血壓,但整體族群中未顯著優於安慰劑。研究人員認為此技術安全且具推廣潛力,但需更大規模試驗進一步驗證。

高血壓是全球常見慢性疾病,許多患者即使服用藥物仍無法達到理想血壓目標,長期高血壓會增加心血管疾病風險。科學界正探索非藥物治療方式,如神經調節技術,以補充現有治療選項。

〔編譯謝宜哲/綜合報導〕英國1項測試小型耳部刺激裝置的實驗發現,該裝置或許能幫助藥物控制效果不佳、血壓持續偏高的患者降低血壓。此研究發表在《高血壓》期刊上。
根據科學網站《SciTechDaily》報導,尋找更多控制血壓的方法非常重要,因為許多正在接受治療的人,血壓仍然高於建議的目標值。長期血壓偏高會增加罹患心血管疾病的風險,包括心肌梗塞與中風。對此從事生物電子醫學與神經調節醫療技術的英國公司「Afferent Medical Solutions」,開發出透過耳部刺激神經系統的獨特裝置。

該裝置透過兩個夾在耳屏上的夾具傳遞溫和電脈衝,作用目標為自主神經系統。該套神經系統負責調節許多不受意識直接控制的身體功能,其中包括血壓調節。英國倫敦瑪麗女王大學的研究團隊,在實驗中測試該裝置能否幫助高血壓患者降低血壓。
這項實驗納入63名高血壓患者,雖然他們有服用1種或多種降血壓藥物,但高血壓仍未獲得有效控制。研究團隊將參與者隨機分配至2組,第一組接受真正的電刺激治療,第二組使用安慰裝置(不提供有效刺激的裝置),以比較2組的治療結果。
在試驗的前2週,參與者每天使用裝置30分鐘,接下來的10週,則改為每週使用1次裝置。參與者大致遵守治療時程,且在整個試驗期間該治療展現出良好安全性與耐受性。
試驗結果顯示,在整體研究族群中真正接受電刺激治療的患者,其血壓下降幅度未顯著大於使用安慰裝置的患者。但研究團隊事先規劃的族群分析顯示,對於試驗開始時高血壓程度較嚴重的患者來說,接受實際電刺激治療後血壓降幅比安慰裝置組大。
研究團隊表示,這是一項令人振奮、且高血壓患者接受度相當高的技術,最終有望為數百萬人提供1種成本低廉、能夠大規模推廣的解決方案。研究人員聲稱,這項試驗指出重要新研究方向,有助於科學家進一步理解,非侵入性神經調節是否能幫助部分血壓控制不佳的患者改善病情。
研究團隊強調,未來仍需要進行規模更大的臨床試驗,並針對特定高血壓患者族群進行研究,以確認究竟哪些患者能從此治療方式中受益。

Northwestern University and the Buck Institute on Aging collaborated to analyze healthy ovarian tissue from 28 menopausal women and found that protein composition changes with age, and found clues related to inflammation, tissue fibrosis and ovarian cancer. The results were published in "Aging Cells".

The "Dementia Research Office" of the National Center for Aging Medicine and Health and Welfare Research of the National Institutes of Health was inaugurated on the 19th. DPP Yunlin County Governor candidate and legislator Liu Jianguo attended the event and said that Taiwan's dementia population is about 400,000 and rising rapidly. He hopes to integrate industry, government, academia and research through the research office so that research results can be introduced into families and communities to build a complete dementia protection network.
The National Medical Insurance Administration announced that the medical insurance wallet version 2.0 has been fully launched nationwide, realizing the cross-provincial sharing of employee medical insurance accounts, supporting online multi-channel and offline processing, further reducing the medical burden of insured people across provinces, and improving the efficiency of fund use.
On October 18, 2026, Meinian Health released the "Meinian Health 2025 Health Examination Big Data Blue Book" in Jinan. The report is based on 19.8 million adult physical examination samples across the country, revealing major national health risks such as nodules and metabolism, as well as regional and gender differences.

Special recycling bins for e-cigarettes have been on the road for a month, and 633 kilograms of e-cigarettes, or about 12,660 e-cigarettes, have been recycled in Taiwan. The National Education Action Alliance and other civil groups call on the Legislative Yuan to complete the third reading of the amendment to the Tobacco Harm Prevention Law during the session, which will include penalties for possession of e-cigarettes, strengthen the management of illegal supply and online platforms, and increase the graphic and text area of cigarette packs to 85%.

The Breast Medicine Center of TECO General Hospital has introduced a high-end ultrasound imaging scanner to improve the early detection rate of breast cancer. The article compares two patients: Ms. Lin was diagnosed with stage zero breast cancer due to public-funded screening and recovered with only local excision and radiation therapy; Ms. Zhang developed locally advanced breast cancer due to delayed medical treatment and required painful treatments such as pretreatment chemotherapy and total mastectomy. Doctors pointed out that the age at which breast cancer is most common in Taiwanese women is about 10 years younger than that in Europe and the United States. The five-year survival rate for early detection exceeds 99%, while at the later stage it drops to about 40%. Starting from 2025, the government will expand breast cancer screening subsidies to women aged 40 to 74, provide free mammograms every two years, and remind them to seek medical attention immediately if abnormalities occur.
