《PUSH手術——彌漫性子宮病變重建生育力手術》詳細介紹了兩種常見育齡婦女子宮彌漫性病變的新手術治療方法，包括彌漫性子宮腺肌病(DAD)和彌漫性子宮肌瘤病(DUL)。這兩種疾病常引發嚴重痛經、月經過多、不孕不育及子宮增大等問題。對於嚴重病例，手術治療是保留和重建生育能力的唯一途徑，也是臨床上的難點。由北京大學深圳醫院吳瑞芳教授和曾荔蘋教授領導的生殖外科團隊研發的 PUSH(protection of uterine structure for healing)手術治療方法，通過徹底切除病灶並保留子宮的關鍵功能結構，成功應用于400余位DAD患者和40余位DUL患者，取得了令人滿意的療效。《PUSH手術——彌漫性子宮病變重建生育力手術》詳細描述了PUSH手術的原理、實施細節和圍手術期管理，強調了術式的特色，同時解答了可能遇到的術中難點問題。這為子宮不同類型和部位的病變提供了個性化的手術設計，為婦產科醫師、子宮疾病專業研究人員及患有彌漫性子宮病變的患者提供了寶貴的資源。

本書譯自奧伯汀?伍德沃德?摩爾(Aubertine Woodward Moore)撰寫的經典音樂指南For Every Music Lover: A Series of Practical Essays on Music。全書共十二講，涵蓋了音樂的各個方面，為音樂愛好者提供了豐富的音樂知識和鑒賞技巧，不僅介紹了音樂的基礎理論，不同音樂流派，西方古典音樂的經典作品和作曲家，如巴赫、貝多芬和莫紮特，還探討了民間音樂和現代音樂的演變。作者結合具體的音樂實例和生動的故事，以深入淺出的講解，幫助讀者建立起對音樂的深刻理解和感性認識，讓複雜的音樂知識變得易於理解。本書寫作風格輕鬆愉快，洋溢著對音樂的熱忱和敬意，讓讀者在閱讀中感受到音樂的無窮魅力。

本書研究了在西方文化語境下，“快樂”含義的演變，以及“快樂”這一情緒概念在文學、哲學創作中的運用。本書的研究時段為中世紀末至21世紀。作者蒂莫西·漢普頓（Timothy Hampton），美國加州大學伯克利分校多琳·湯森人文研究中心（Doreen B.Townsend Center for the Humanities）主任，著有《鮑勃·迪倫:歌曲如何起作用》《大使館小說:近代早期歐洲的文學與外交》。作者認為，從現代早期至當代，“快樂”是西方文學、哲學、藝術創作的重要主題，但因其具有的溫和屬性，一直以來都被文學和哲學研究者所忽略。這也構成了作者寫作的動機。作者在書中追溯了“快樂”的情感源流，追蹤了其在不同文體中的含義的變化——從宗教改革時期的新教神學評論，到現代美學，不一而足。作者以美國新冠疫情大流行時期作為全書的結束，再次強調了“快樂”是一種重要的情感力量，它所具有的至關重要的作用往往在危機時刻得以顯現。在災難的壓力下，“快樂”能讓人保持輕鬆的心態。 作者捕捉到了“快樂”這一轉瞬即逝的、強有力的、變革性的情感的眾多表象，系統地追溯了“快樂”的歷史和文學軌跡。
