全球健康与长寿每日简报Global Health & Longevity Daily Briefing

中江南大学翟齐啸团队在《Gut Microbes》发表综述，系统剖析广谱抗生素如何选择性清除产短链脂肪酸菌与次级胆汁酸转化菌，破坏肠道代谢网络，并与肥胖、糖尿病、过敏等远期慢病风险升高相关。团队提出菌群修复应“从喂菌到修境”：高纤维饮食降低肠腔氧化还原电位、地中海饮食以多酚协同抗炎，为残余有益菌创造再生环境，而非简单“空投”外源益生菌。

ENA review by Quanqi Zhai's team at Jiangnan University in Gut Microbes details how broad-spectrum antibiotics selectively wipe out short-chain-fatty-acid producers and secondary bile acid converters, disrupting gut metabolic networks and raising long-term risks of obesity, diabetes and allergy. The authors argue restoration should shift from "seeding bacteria to rebuilding the environment": high-fiber diets lower colonic redox potential and Mediterranean-style polyphenols curb inflammation, helping residual beneficial microbes regenerate rather than simply transplanting probiotics.

中肠道细菌在消化石榴、核桃、浆果等食物后会产生一类天然化合物，新研究发现其有助于修复和保护肠黏膜屏障。该发现揭示了炎症通路“意外有益”的一面，为炎症性肠病等以肠道屏障受损为特征的疾病提供了基于膳食—菌群代谢物的潜在干预新思路。

ENA natural compound produced by gut bacteria after digesting foods such as pomegranates, walnuts and berries may help repair and protect the intestinal lining, new research shows. The finding reveals a surprising beneficial side of an inflammatory pathway and points to diet-microbiome metabolites as a potential avenue for conditions marked by gut barrier damage, including inflammatory bowel disease.

中上海中医药大学包春辉团队在《Current Obesity Reports》发表综述，提出以内脏脂肪为核心的菌群—肠—脑轴模型：内脏脂肪扩张伴随产短链脂肪酸菌减少与促炎菌群富集，肠屏障紧密连接蛋白下调后脂多糖入血，经受损血脑屏障激活胶质细胞，损伤海马与下丘脑。综述强调腰围与腰臀比对认知风险的分层价值优于BMI，减重诱导的内脏脂肪减少与认知改善相关。

ENA review from Baobiao Bao's team at Shanghai University of TCM in Current Obesity Reports proposes a visceral-fat-centered microbiota-gut-brain axis model: expanding visceral fat depletes SCFA producers and enriches pro-inflammatory taxa; gut barrier tight-junction proteins fall, letting LPS enter circulation, cross a weakened blood-brain barrier, activate glia and impair the hippocampus and hypothalamus. Waist circumference and waist-to-hip ratio stratify cognitive risk better than BMI, and weight-loss-driven visceral fat reduction tracks cognitive improvement.

中功能医学从业者Yoon Hang Kim发文系统梳理菌群移植现状：在复发性艰难梭菌感染中已进入标准临床路径，REBYOTA与VOWST两款FDA批准产品可用，核心机制是定植抗力、胆汁酸与短链脂肪酸修复；花生过敏首次人体试验带来概念验证新信号。作者强调FMT是“微生物生态修复疗法”，并非通用益生菌或长寿干预，需严格供体筛选与适应证管理。

ENWriting for clinicians, Yoon Hang Kim reviews the state of FMT: it is standard care for recurrent C. difficile infection with two FDA-approved products (REBYOTA, VOWST), working mainly via colonization resistance, bile-acid and SCFA restoration; a first-in-human peanut allergy trial offers a new proof-of-concept signal. He stresses FMT is a "microbial ecosystem restoration therapy" — not a general probiotic or longevity intervention — requiring strict donor screening and indication control.

中AI制药公司英矽智能的rentosertib取得里程碑进展：42名平均67岁受试者服药四周后，近3000种血浆蛋白发生变化，六套生物年龄模型评估生理年龄普遍年轻3至4岁、最高近6岁；相关蛋白组衰老时钟分析已发表于《自然》。9月10日，全球首个AI生成式药物III期试验GENESIS-IPF-3完成首例患者给药，拟在全国47家中心入组320人。

ENInsilico Medicine's AI-designed rentosertib hit a milestone: 42 participants averaging 67 years old showed changes in nearly 3,000 plasma proteins after four weeks, with six biological-age models estimating physiological age reversals of 3-4 years on average and nearly 6 at best; the proteomic aging-clock analysis was published in Nature. On September 10 the first patient was dosed in GENESIS-IPF-3, the first Phase III trial of a generative-AI drug, planning 320 participants across 47 Chinese centers.

中《自然》最新研究显示，对20月龄（约相当于人类老年）雌性小鼠给予司美格鲁肽，可将中位剩余寿命从742天延长至834天，并改善多项衰老相关指标，提示GLP-1类药物的获益可能超越减重与代谢改善，直接作用于衰老生物学通路。研究者提醒，该结果来自动物模型，人体证据仍缺乏，不能据此将减肥药当作长寿药使用。

ENA new Nature study shows semaglutide given to 20-month-old (roughly elderly) female mice extended median remaining lifespan from 742 to 834 days and improved multiple aging markers, suggesting GLP-1 drugs may act on aging biology itself beyond weight loss and metabolic gains. The authors caution the findings are in animals, human evidence is lacking, and weight-loss drugs should not be taken as longevity drugs.

中据CiVL汇总的近30天长寿临床试验动态，Life Biosciences已完成细胞部分重编程疗法（OSK，靶向青光眼/视神经病变）首例患者给药，成为该路线首个进入人体给药的项目；同期Cedars-Sinai长寿试验由N/A升格为I/II期、扩容至60人并新增试验臂。全球活跃长寿临床试验达43项，其中21项正在招募，衰老干预从动物研究加速走向人体验证。

ENAccording to CiVL's roundup of the past 30 days in longevity trials, Life Biosciences has dosed the first patient with a partial cellular reprogramming therapy (OSK, targeting glaucoma/optic neuropathy), the first such candidate to reach human dosing. In parallel, Cedars-Sinai's longevity trial was upgraded to Phase 1/2, expanded to 60 participants and gained a third arm. Forty-three active longevity trials are now tracked, 21 of them recruiting — accelerating the shift from animal work to human validation.

中长寿临床试验追踪平台CiVL显示，雷帕霉素抗衰证据链快速推进：低剂量雷帕霉素处理使人体面部皮肤样本中的衰老细胞减少约一半；亚利桑那大学正筹备一项面向老年人的720人雷帕霉素大型研究。这是雷帕霉素从动物延寿数据迈向人体组织与临床验证的关键一步，剂量与获益风险比仍是核心议题。

ENCiVL's longevity trial tracker shows the rapamycin evidence base moving fast: low-dose rapamycin cut senescent cells by roughly half in human facial skin samples, and the University of Arizona is preparing a 720-person rapamycin study in older adults. It marks a key step from animal lifespan data toward human tissue and clinical validation, with dosing and benefit-risk balance still the core questions.

中TimeShop“逆时·新生”2026全球长寿营养峰会在上海举行，提出针对慢性炎症、肠道微生态失衡与细胞代谢衰退三条通路的“肠道微生态+细胞代谢”双靶点精准干预。香港中文大学黄世万教授分享源自中国长寿之乡百岁老人的AKK001菌株，称其在耐胃酸、耐胆汁及抗炎蛋白表达上优于多国菌株；Brian Kennedy解读Ca-AKGd作用机制与最新人体临床证据。

ENAt TimeShop's 2026 Global Longevity Nutrition Summit in Shanghai, the brand proposed a dual-target "gut microbiota plus cell metabolism" approach to precision nutrition addressing chronic inflammation, dysbiosis and metabolic decline. CUHK's Sai-Wan Wong presented AKK001, a strain from centenarians in a Chinese longevity village reported to outperform multinational strains in acid/bile tolerance and anti-inflammatory protein expression, while Brian Kennedy discussed Ca-AKGd mechanisms and human trial evidence.

中FrieslandCampina资助的新研究显示，补充DHA或能改善女性运动员的红细胞功能并提升耐力表现，为Ω-3脂肪酸在运动营养中的性别差异化应用提供了新证据。研究提示女性运动员对脂肪酸利用与炎症恢复的需求可能与男性不同，按性别与个体状态定制Ω-3摄入策略，正在成为精准营养在运动人群中的新方向。

ENNew FrieslandCampina-funded research suggests DHA supplementation may improve red blood cell function and support endurance performance in female athletes, adding sex-specific evidence for omega-3s in sports nutrition. The findings hint that women's fatty-acid utilization and recovery needs may differ from men's, making individualized omega-3 strategies an emerging direction for precision nutrition in athletic populations.

中央视网健康频道科普梳理指出，控“三高”的关键不是“不吃”而是“会吃”：豆类及豆制品富含优质蛋白、不饱和脂肪酸、膳食纤维、钾与大豆异黄酮，有助于改善血糖、降低血脂并保护血管，这也与国家“减油、增豆、加奶”的膳食倡导一致。文章提醒把豆类纳入日常膳食结构，比单纯限制肉类和主食更可持续。

ENA CCTV health channel explainer argues the key to managing blood sugar and lipids is eating smarter, not simply eating less: beans and soy products deliver quality protein, unsaturated fatty acids, fiber, potassium and soy isoflavones that help improve glucose and lipid profiles and protect blood vessels, echoing China's "less oil, more beans and dairy" dietary guidance. Incorporating beans into daily meals is more sustainable than blanket restriction of meat and staples.

中发表于《Cell》的中国科研成果显示，益生菌Lc19能生成全新代谢活性物质Trp-CA，可同时影响血糖与体重。9月20日发布的科普视频走进北大、中国农大与蒙牛研发中心，对话庞艳莉、赵亮、毛跃建等专家，讲述这株源自长寿之乡的菌株历经17年、从2万株中筛选验证的科研历程，为“本土菌株+精准代谢物”的控糖与体重管理路径提供范例。

ENA Chinese study published in Cell shows the probiotic strain Lc19 produces a novel bioactive metabolite, Trp-CA, that influences both blood glucose and body weight. A popular-science video released September 20 visits Peking University, China Agricultural University and Mengniu's R&D center, with experts Pang Yanli, Zhao Liang and Mao Yuejian recounting how the strain from a longevity region was validated over 17 years from 20,000 candidates — a template for "local strains plus precision metabolites" in glucose and weight management.

中发表于《自然·医学》的COSMOS随机对照试验分析显示，958名平均70岁的健康老人每日服用复合维生素两年，PCGrimAge与PCPhenoAge两种表观遗传时钟的衰老速度显著减慢，约相当于每年减缓1.4-2.6个月，基线生物年龄大于实际年龄者获益更明显。专家强调效应微小且未在所有时钟上一致，可能仅反映营养缺口的纠正，复合维生素不能替代健康饮食与运动。

ENA Nature Medicine analysis of the COSMOS randomized trial found that 958 healthy adults averaging 70 years who took a daily multivitamin for two years showed significantly slower aging on the PCGrimAge and PCPhenoAge epigenetic clocks — roughly 1.4-2.6 months per year — with larger benefits in those whose baseline biological age exceeded chronological age. Experts stress the effect is tiny, inconsistent across clocks, and may simply reflect correcting nutrient gaps; multivitamins cannot replace diet and exercise.

中一项涵盖超过15.3万名成年人的大型综述发现，钙与维生素D补充剂——无论单独还是联合服用——对大多数老年人预防骨折或跌倒的作用微乎其微。研究挑战了数百万人日常补钙护骨的惯例，提示补剂策略应回归个体化：对确有缺乏或高危人群仍可能获益，而普遍性补充的公共卫生价值有限，均衡膳食与抗阻运动仍居核心。

ENA large review covering more than 153,000 adults finds that calcium and vitamin D supplements — alone or combined — offer minimal protection against fractures or falls for most older adults. The finding challenges the routine of mass calcium supplementation for bone health and argues for individualized strategies: those with true deficiency or high risk may still benefit, while population-wide supplementation shows limited public-health value compared with balanced diets and resistance exercise.

中在香港TimeShop全球长寿营养峰会上，品牌发布新品“轻松镁”，采用Epsomax-4纳米速吸技术的条装液态镁制剂，针对镁补充普遍存在的吸收难问题。镁参与300余种酶促反应并关联睡眠、压力与糖脂代谢，液态纳米递送成为补镁产品差异化竞争点，也折射出长寿营养品类从单一原料向递送技术升级的趋势。

ENAt TimeShop's Global Longevity Nutrition Summit in Shanghai, the Hong Kong brand launched "Easy Magnesium," a stick-pack liquid magnesium using Epsomax-4 nano rapid-absorption technology aimed at magnesium's well-known absorption problem. Magnesium participates in over 300 enzymatic reactions tied to sleep, stress and glucose-lipid metabolism, and liquid nano-delivery is becoming a differentiation point — reflecting the longevity-nutrition category's shift from single ingredients to delivery-technology upgrades.

中NutraIngredients专访Dr. Wasabi，探讨源自十字花科蔬菜（如芥末、西兰花芽）的稀有硫化物Hexaraphane在大脑健康领域的潜力。作为6-（甲硫基）己基异硫氰酸酯类成分，其相关研究正从食用历史与安全性评估走向认知功能方向的探索，或将成为继萝卜硫素之后功能原料市场的新晋“明星分子”，尚需更多人体证据支持。

ENNutraIngredients talks with Dr. Wasabi about hexaraphane, a rare organosulfur compound from cruciferous vegetables such as wasabi and broccoli sprouts, and its brain-health potential. Research on this 6-(methylthio)hexyl isothiocyanate is moving from food-use history and safety evaluation toward cognitive function exploration, positioning it as a potential follow-up to sulforaphane in functional ingredients — though more human evidence is still needed.

中据OpenLoop九月数字健康动态汇总，超过200家医疗机构联合敦促美国医保与医疗补助服务中心（CMS）重新考虑拟议中的Medicare变更——新规将限制第三方临床人员参与远程监测服务。行业组织警告，政策若落地可能干扰约100万Medicare受益人的远程照护，农村与安全网医疗机构受冲击最大，远程健康管理商业模式面临政策不确定性。

ENOpenLoop's September digital health roundup reports that more than 200 healthcare organizations are urging CMS to reconsider proposed Medicare changes that would limit third-party clinical staff in remote monitoring services. Industry groups warn the policy could disrupt remote care for roughly 1 million Medicare beneficiaries, hitting rural and safety-net providers hardest — underscoring the policy uncertainty facing remote health-management business models.

中央视网引用一项随访长达40年的大型研究指出，中年是长寿最关键的干预窗口期：管好血压、血糖、血脂、体重与吸烟等5项指标，活到90岁的几率可提升5倍，中年管好这些指标与延寿近11年相关。自带长寿基因者若生活方式紊乱同样难以长寿，健康科学的生活方式可以弥补基因劣势，中年阶段的行为改变回报最高。

ENCiting a 40-year follow-up study, CCTV's health channel highlights midlife as the most critical intervention window for longevity: keeping five metrics in check — blood pressure, blood glucose, blood lipids, body weight and smoking — can raise the odds of reaching age 90 fivefold and is associated with nearly 11 extra years of life. Even those with longevity genes lose the advantage with poor lifestyles, and behavioral change in midlife yields the highest returns.

中央视网报道，同一人用两台不同品牌体脂秤测出的体脂率可相差悬殊（实测37.1%与24%）。专家解释，体脂秤并非直接“称”脂肪，而是先测生物电阻抗、再结合体重等数据用各家算法估算，模型不同结果自然有别。建议把体脂秤作为趋势监测工具，关注两到四周的变化方向而非单次读数的绝对值，健康管理决策应结合腰围、血液指标等综合判断。

ENCCTV reports that the same person can register wildly different body-fat readings on two consumer scales (37.1% vs 24% in one test). Experts explain these devices don't measure fat directly: they take bioelectrical impedance and estimate body fat via each brand's proprietary algorithm, so results vary. The advice: use a body-fat scale as a trend tool, watching two-to-four-week direction rather than absolute single readings, and ground health decisions in waist circumference and blood markers.

中每年9月15日所在周为中国减盐周，“915”寓意“就要5克”。我国成人日均盐摄入约9.3克，远超5克建议量，高盐升高血压并增加心脑血管病、肾病、骨质疏松、胃癌和肥胖风险。专家提醒警惕挂面、面包等隐形高盐食品与营养成分表的“缩水”标注，善用限盐工具、外卖备注少盐、逐步减量，慢病患者每日建议不超3克。

ENThe week of September 15 is China's Salt Reduction Week — "915" punning on "just 5 grams." Chinese adults average about 9.3 grams of salt daily, nearly double the 5-gram recommendation, raising risks of hypertension, cardiovascular and kidney disease, osteoporosis, gastric cancer and obesity. Experts urge watching hidden salt in dried noodles and bread, checking nutrition labels, using salt-limiting tools, requesting less salt in takeout and cutting back gradually; chronic-disease patients should stay under 3 grams a day.
