  115. <section class="section">
  116. <h2>📌 这个指标是什么?</h2>
  117. <p class="section-intro">疾病风险评估模块包含18项疾病风险预测,每项以0-1的指数表示。这个指数不是"你有没有这个病",而是"基于你当前的菌群状态,患这类疾病的风险相对高低"。</p>
  118. <div class="card">
  119. <h3>风险指数的含义</h3>
  120. <p>报告会用颜色标注三个区间:</p>
  121. <div class="risk-bar">
  122. <span class="risk-label low">&lt;0.3 低风险</span>
  123. <div class="risk-bar-track"><div class="risk-bar-fill risk-low" style="width:30%"></div></div>
  124. </div>
  125. <div class="risk-bar">
  126. <span class="risk-label mid">0.3-0.5 注意</span>
  127. <div class="risk-bar-track"><div class="risk-bar-fill risk-mid" style="width:50%"></div></div>
  128. </div>
  129. <div class="risk-bar">
  130. <span class="risk-label high">&gt;0.5 高风险</span>
  131. <div class="risk-bar-track"><div class="risk-bar-fill risk-high" style="width:75%"></div></div>
  132. </div>
  133. <p style="margin-top:1rem;">需要强调:<strong>风险指数≠确诊</strong>。它是基于大规模人群数据建立的菌群-疾病关联模型,告诉你"方向",不告诉你"结论"。高风险值提示你需要关注这个方向,并结合临床检查做进一步评估。</p>

  135. </div>
  136. <div class="card">
  137. <h3>18项疾病风险涵盖哪些?</h3>
  138. <ul class="list-styled">
  139. <li><strong>消化系统:</strong>炎症性肠炎(IBD)、肠易激综合征(IBS)、结直肠癌、便秘</li>
  140. <li><strong>代谢系统:</strong>II型糖尿病、肥胖、心脑血管疾病</li>
  141. <li><strong>神经精神:</strong>抑郁症、失眠、自闭症</li>
  142. <li><strong>免疫相关:</strong>过敏、甲状腺疾病</li>
  143. <li><strong>其他:</strong>非酒精性脂肪肝、牙周病等</li>

  149. <h2>🔍 报告怎么看?</h2>
  150. <p class="section-intro">拿到报告后,不要被18项数字吓到。重点看三类:跟自己相关的、明显偏高的、以及综合评分。</p>
  151. <div class="card">
  152. <h3>第一步:先看"相关性"</h3>
  153. <p>你有便秘困扰?先找"便秘"那项。你有家族糖尿病史?先找"II型糖尿病"。不要试图一次看完18项——先聚焦跟你最相关的2-3项。</p>
  154. </div>
  155. <div class="card">
  156. <h3>第二步:看颜色和数值</h3>
  157. <p>绿色(&lt;0.3)= 暂时安全,保持现有饮食和生活习惯即可。橙色(0.3-0.5)= 黄灯,提示你这个方向有风险趋势,建议调整饮食结构或补充特定益生菌。红色(&gt;0.5)= 红灯,建议结合临床检查(如肠镜、血糖检测),同时进行针对性菌群干预。</p>
  158. </div>
  159. <div class="card">
  160. <h3>第三步:看"菌群-疾病"关联描述</h3>
  161. <p>报告通常会说明"为什么这项风险高"——比如"产丁酸菌不足""具核梭杆菌偏高"等。这些才是干预的真正靶点。</p>
  162. </div>
  163. </div>
  164. </section>
  165. <section class="section">
  166. <h2>⚠️ 异常了意味着什么?</h2>
  167. <p class="section-intro">以最常见的三种高风险为例:</p>
  168. <div class="card">
  169. <h3>结直肠癌风险偏高</h3>
  170. <p>典型菌群信号:具核梭杆菌(Fusobacterium nucleatum)超标、产丁酸菌(如普拉梭菌)缺失、次级胆汁酸偏高。</p>
  171. <p><strong>该怎么办:</strong>建议做一次肠镜检查排除器质性问题;同时增加膳食纤维摄入(每天25-30g),补充抗性淀粉和低聚果糖(FOS)促进产丁酸菌恢复。</p>
  172. </div>
  173. <div class="card">
  174. <h3>II型糖尿病风险偏高</h3>
  175. <p>典型菌群信号:产丁酸菌丰度降低、普雷沃氏菌过度增殖、乙酸盐/丙酸盐比例失调。</p>
  176. <p><strong>该怎么办:</strong>检测空腹血糖和糖化血红蛋白;增加全谷物和豆类摄入(提供抗性淀粉);减少精制碳水;考虑补充特定乳杆菌菌株。</p>
  177. </div>
  178. <div class="card">
  179. <h3>抑郁症/失眠风险偏高</h3>
  180. <p>典型菌群信号:双歧杆菌缺乏、另枝菌属(Alistipes)超标、GABA/血清素代谢异常。</p>
  181. <p><strong该怎么办:</strong>关注肠-脑轴健康;增加发酵食品(酸奶、泡菜);补充含有动物双歧杆菌BB-12或乳杆菌HN019的益生菌;保持规律作息。</p>
  182. </div>
  183. <div class="highlight-box green">
  184. <p><strong>核心原则:</strong>风险指数是"起点",不是"终点"。高风险值 = 该做进一步检查了 + 该调整菌群了。不要恐慌,也不要忽视。</p>

  188. <div class="section-inner">
  189. <h2>🛠️ 怎么改善?</h2>
  190. <ul class="list-styled">
  191. <li><strong>增加膳食纤维:</strong>每天25-30g,蔬菜、水果、全谷物、豆类是天然来源</li>
  192. <li><strong>补充特定益生菌:</strong>根据高风险对应的菌群缺陷,选择针对性菌株(不是"随便买一盒益生菌")</li>
  193. <li><strong>减少促炎食物:</strong>精制糖、加工肉类、反式脂肪会加剧菌群失调</li>
  194. <li><strong>定期复查:</strong>干预3-6个月后复查,对比风险指数变化</li>
  195. <li><strong>结合临床检查:</strong>高风险项建议做对应的医学筛查(肠镜、血糖、甲状腺功能等)</li>
