人民网北京12月17日电 （记者乔业琼）据中疾控微信公众号消息，又到了冬令进补的时候，短视 频平台上，一盘盘"晶莹剔透"的生鱼片，配上"鲜甜脆嫩，一口入魂"的解说词，刺激着人们追求新奇美 食的欲望。但很少有人知道，这份"鲜美"背后，可能潜伏着一个致命威胁——肝吸虫（学名"华支睾吸 虫"）。今天就带大家看清肝吸虫的真面目。 肝吸虫虫卵经粪便排出体外，在水中被淡水螺吞食，在螺体内开始孵化，开启无性增殖。 第二步：在第二中间宿主体内结囊 每颗虫卵在螺体内经过无性增殖后，都会变成无数个尾蚴从螺体内逸出，尾蚴在水中遇到淡水鱼便 迅速钻入鱼体内，每条尾蚴都能在肌肉里发育成一颗囊蚴。 第三步：通过摄食侵入终宿主 待囊蚴在鱼体内发育成熟后，便迎来了最关键的一步：侵入终宿主。但这一步光靠它自己是完成不 了的，必须有"贵人"相助。喜食生鱼片的人便充当了这个关键角色，为肝吸虫完成生活史，壮大种群数 量做出了巨大"贡献"。 表面看上去晶莹剔透的生鱼片，在显微镜下并不一定干净，含有囊蚴的生鱼片进入人体消化道后， 囊蚴在消化液的刺激下脱囊成为幼虫，幼虫沿肠道钻入肝胆管并在此定居，经过一个月发育为成虫开始 产卵，肝吸虫一个完整的生活史就这 ...

Core Viewpoint - The article emphasizes the importance of health maintenance during the Frost's Descent period, focusing on dietary adjustments, lifestyle changes, and exercise recommendations to prepare for winter [1][2]. Dietary Recommendations - The focus should be on "warming and moisturizing" foods, such as tremella, lily bulbs, honey, and black sesame [1]. - Foods that enhance spleen and stomach function, like yam, pumpkin, glutinous rice, lotus seeds, and coix seeds, are recommended to counteract the cold [1]. - Residents are advised to avoid cold foods like ice drinks, sashimi, and watermelon, which can harm the spleen and stomach, potentially leading to diarrhea and abdominal pain [1]. - Spicy foods, including chili and fried items, should also be avoided as they can exacerbate dryness and lead to symptoms like dry mouth, sore throat, and constipation, especially for those prone to heat [1]. Lifestyle Adjustments - With the increase in cold, it is crucial to maintain warmth to prevent cold-related symptoms such as headaches and colds [1]. - After washing hair, it is important to dry it promptly to avoid sleeping with wet hair, and wearing a knitted hat outdoors is recommended to protect the head from cold [1]. - Foot warmth is emphasized, with advice to avoid exposing ankles and to soak feet in warm water (40-45°C) for about 20 minutes before bed, depending on personal comfort [1]. Exercise Recommendations - During the Frost's Descent period, high-intensity workouts should be avoided; instead, gentle exercises like Baduanjin, Tai Chi, and yoga are suggested [2]. - Proper warm-up before exercising is essential, and individuals should not immediately reduce clothing after workouts to prevent exposure to cold [2].
