Group 1: Sleep Disorders in the Elderly - Over half of the elderly population in China experiences sleep disorders, significantly reducing their quality of life [2] - A study involving over 9,000 participants aged 60 and above found that 53.8% reported at least one sleep disorder, with difficulties in falling asleep and waking up more than twice at night reported by 27.5% and 27.8% respectively [2] - Chronic insomnia is defined as experiencing typical symptoms such as difficulty falling asleep and waking up multiple times at least three times a week for over three months [2] Group 2: Causes of Insomnia in the Elderly - Insomnia in the elderly is attributed to complex physiological and psychological factors, including decreased melatonin secretion and chronic health issues [3] - Common health problems affecting sleep include coughing, frequent urination, joint pain, and limited mobility [3] - Psychological factors such as reduced social interaction and health-related anxiety can lead to feelings of depression and anxiety, further impacting sleep quality [3] Group 3: Strength Training as a Solution - A recent meta-analysis found that strength training is particularly effective in improving sleep quality among the elderly [4] - The analysis included 25 randomized controlled trials with data from 2,170 participants, assessing the impact of different types of exercise on sleep quality [4] - Both strength training and aerobic exercise groups achieved clinically significant improvements in sleep quality [5] Group 4: Recommended Strength Training Methods - Three types of strength training suitable for the elderly include bodyweight exercises, resistance band training, and gym equipment training [6] - Bodyweight exercises such as squats and wall push-ups are simple and require no additional equipment, making them ideal for beginners [6] - Resistance band training can effectively target major muscle groups and is portable for home or outdoor workouts [6] Group 5: Guidelines for Elderly Strength Training - It is important for the elderly to start strength training gradually, beginning with simple movements and progressively increasing intensity [7] - Training sessions should last 20-30 minutes and occur every other day to allow for adequate recovery [7] - Warm-up and stretching exercises before and after training are essential to prevent injuries [7] Group 6: Importance of Sleep Health - Sleep quality is closely linked to overall health, affecting psychological well-being, emotional regulation, and cognitive function [8] - Short-term sleep deprivation can lead to mood swings and decreased attention, while long-term sleep issues increase the risk of serious health conditions [8]

Core Viewpoint - The article discusses new treatment methods for allergies, particularly during the high pollen season, emphasizing the importance of timely intervention to prevent minor symptoms from escalating into serious issues [1]. Group 1: Allergy Symptoms - Four key symptoms signal the onset of allergic rhinitis: frequent sneezing, nasal itching, excessive nasal discharge, and nasal congestion [2][3][4][5][6]. Group 2: Treatment Methods - Two innovative treatments are introduced: the stellate ganglion block and the pterygopalatine ganglion block, both of which are effective in alleviating allergy symptoms by temporarily suppressing overactive nerve functions [7][10]. - The stellate ganglion block involves ultrasound-guided injection around the stellate ganglion to reduce inflammation and calm the immune response, thereby improving symptoms like nasal congestion and sneezing [8]. - The pterygopalatine ganglion block targets the deep nasal pterygopalatine ganglion to interrupt allergy signals to the brain, balancing the autonomic nervous system and reducing nasal hyperreactivity [10]. Group 3: Suitable and Unsuitable Patient Groups - Suitable candidates for the stellate ganglion block include those who have persistent allergy symptoms despite medication and those experiencing insomnia or headaches [9]. - Unsuitable candidates for this treatment are individuals with bleeding disorders, neck infections, severe heart or lung diseases, and glaucoma [10]. - Suitable candidates for the pterygopalatine ganglion block are those suffering from severe nasal congestion and those hesitant to use steroid medications [11]. - Unsuitable candidates for this treatment include individuals with a history of nasal surgery, nasal deformities, and needle phobia [12].

日前有新闻报道称，男子因爱挖鼻孔最终导致动脉血管破裂，不得不进行手术修复。乍一听，是不 是让你大跌眼镜？该话题也一度冲上新闻热搜榜。 毫不夸张地说，抠鼻子这个小动作若是操作不当，确实隐藏着"要命"的大危险。正值春季天气干 燥，加之"过敏星人"增多，鼻干鼻痒在所难免。今天，医生就来跟大家分享，那些抠鼻子不得不知的小 知识。 鼻子为什么容易出血 鼻子为什么一抠就会爱出血？那是因为鼻黏膜较薄，又含有丰富的毛细血管网，是临床上最常见的 鼻出血区，我们又称之为易出血区。约90%的鼻出血发生于此。 当娇嫩脆弱的鼻黏膜，遇上过于尖利的手指甲，或者是抠鼻子的力度过大，就很容易造成鼻腔黏膜 的破烂，进而引发流鼻血的现象。除此之外，对于鼻腔内有血管瘤的患者来说，如果不小心抠到了鼻腔 内的血管瘤等组织，也会导致其破裂，出现流鼻血的情况。 当然了大多数鼻出血是轻微的，通过按压就可以止住。但如果压迫止血后仍然持续出血、出血量 大，连续滴下或形成血流，甚至血流如注、患者呼吸困难、疲惫甚至意识模糊，需要尽快就医处理。 小动作还可引发致命危机 为什么大人、小孩子都喜欢抠鼻子呢？从鼻腔的生理结构上讲，鼻子的空间本来就小，如果有硬硬 的鼻屎在里 ...

Core Viewpoint - The newly revised National Food Safety Standard for Prepackaged Food Labeling introduces a "consumption preservation period" that allows food producers to voluntarily indicate the last consumption date based on food attributes and consumption characteristics, aiming to reduce food waste and provide clearer information to consumers [1][3]. Group 1: Regulatory Changes - The National Health Commission and the State Administration for Market Regulation released 50 food safety standards and 9 amendments, focusing on public concerns and industry development needs, ensuring interconnection and coordinated management of food safety risks [1]. - The introduction of the "consumption preservation period" system is a significant highlight of the new food safety standards, addressing consumer needs for consuming food beyond the expiration date [1][3]. Group 2: Consumer Awareness - Many consumers mistakenly believe that the expiration date is synonymous with the safety period, leading to confusion about the safety of slightly expired food [2]. - The "consumption preservation period" is intended to provide consumers with clear guidance, helping them understand the safety threshold for consuming slightly expired food without encouraging the consumption of expired products [3]. Group 3: International Practices - Several countries have established a "consumption preservation period" alongside best taste or best consumption periods, aligning with international practices and consumer habits [3]. - The voluntary labeling of the "consumption preservation period" allows consumers to make informed decisions about consuming slightly expired food, thereby reducing food safety risks and preventing waste [3].

近日，华南理工大学教务处官网公布了2024-2025学年第二学期全校本科生学业预警名单。学校称，经 审查决定给予全校(包括三个校区)共737名学生学业预警，给予134名学生学业预警并第一次降级试读， 给予81名学生学业预警并再次降级试读。此前，广东医科大学、华中科技大学、深圳技术大学等高校也 公布了学业预警结果。(3月26日《中国青年报》) 对表现不佳的学生进行学业预警，就像体育比赛中的"黄牌警告"，这不是将涉事学生"罚下场"，而是对 他们进行警示、敲打，如果学生屡教不改，则可能被"红牌罚下"。这对学生而言，是一个新的机会，目 的是为了督促他们认真完成学业。 一段时间里，一些高校都存在"严进宽出"的问题，这让一些学生误认为进入大学后就可以置课业于不 顾，即便是"混日子"，也能大概率顺利毕业。如果大学文凭、硕士学位、博士学位都能靠"混日子"轻松 取得，那相对应的教育含金量自然也就大打折扣了。为了确保教学质量，培养高素质人才，高校需要采 取"严进严出"的教育模式。学业预警机制对学生而言，是及时且必要的提醒，能够在学生学习出现偏轨 时及时督促他们，确保他们能够保质保量完成学业任务。 近年来，越来越多的高校对学生"混 ...

泰康之家张子维 以"文化养老"重构银发经济价值内核 中国加速步入深度老龄化的当下，传统养老模式已难以满足老年人对生活品质与精神价值的双重需 求。泰康之家北京分公司总经理张子维以燕园社区为样本，生动阐述了"文化养老"如何重塑长者价值。 从社区内90岁以上长者专属门球场，到80岁以上台球室等差异化设计，无一不体现着对高龄群体的 尊重。张子维提出，"文化养老"的核心在于激活长者的"第二次生命"。区别于传统养老机构对基础照护 的单一关注，泰康之家将"文化养老"提升至战略高度，十余年来以创新实践，力促养老从基础生存保障 转向对生命尊严与价值延续的深度关怀。 她特别分享了由中科院教授主导的"科学大讲堂"案例，探讨区块链、AI等前沿议题的课程场场爆 满。这种"俱乐部自治"模式，让高龄长者们在专属空间里，通过社交参与重拾尊严与归属感，在价值创 造和延续中实现从"养老"到"享老"的跨越。 文/孟思雨 张思锐 北京青年报记者 范辉 "养老不仅是生存需求，更是品质追求""养老产业的终局不是资产规模竞赛，而是服务颗粒度的较 量""当90%老人选择居家养老时，服务触达的'最后一公里'就是创新升级的主战场"……一句句掷地有声 的金句在春 ...

此前，全国检察机关曾开启过"公益诉讼守护美好生活"专项监督活动，将外卖包装材料安全、"网 红代言""直播带货"等涉及食品安全及监管漏洞列为重点监督领域。对于生产、销售有毒有害"减肥神 药"的行为，有关部门应依法严厉打击，提高违法成本，以典型案例有效震慑不法分子。通过公益诉讼 紧盯网络食品安全，以制度刚性筑牢消费者权益的保护屏障，进一步压缩西布曲明制剂的生存空间。 除了对置消费者生命健康于不顾的商家严惩不贷之外，还应关注减肥市场的乱象与公众健康认知的 误区。众所周知，减肥没有捷径。然而，一些商家利用"躺着就能瘦"的虚假宣传，总能精准击中一些人 对快速减肥的心理焦虑。医学早已证明，健康减重必须遵循科学规律：适度运动与合理饮食的有机结 合，循序渐进的生活方式调整，才是可持续的瘦身之道。那些宣称"三天瘦五斤"之类的营销话术，不仅 违背了科学减肥的规律，还涉嫌侵犯消费者的合法权益。正如网友所言，任何违背生理规律的"神药"， 最终都将成为身体难以承受之重。 治理网络食品乱象，需要构建多方协同的治理体系。守土有责的电商平台应切实履行审核义务，对 违规产品坚决下架；监管部门要完善网络销售监管机制，将直播带货、短视频营销等纳入 ...
