目的基于网络药理学结合分子对接,通过临床验证,探讨健脾滋肾方从足细胞自噬途径治疗系统性红斑狼疮(SLE)潜在机制。方法运用TCMSP、GeneCards、OMIM及TTD数据库获取健脾滋肾方及SLE、足细胞自噬相关靶点;取三者交集得到健脾滋肾方经足细胞自噬途径治疗SLE的潜在作用靶点。Cytoscape3.9.1构建“复方-成分-疾病-潜在靶点”网络及蛋白质互作网络,筛选出关键活性成分和靶点,进行分子对接。并临床纳入46例SLE患者和10例健康人,将SLE患者随机分为观察组(n=22)和对照组(n=21)。对照组口服醋酸泼尼松及吗替麦考酚酯,观察组在其基础上加用健脾滋肾方,疗程均为12周。运用ELISA检测SLE组及健康人群尿液中nephrin、synaptopodin水平;使用Western blot检测外周血内p-JAK1/JAK1、pSTAT1/STAT1、LC3II/LC3I、p62蛋白水平,并观察经健脾滋肾方干预后对SLE患者足细胞相关蛋白(nephrin、synaptopodin)、自噬水平(LC3II/LC3I、p62)及p-JAK1/JAK1、p-STAT1/STAT1表达影响。结果经筛选得到健脾滋肾方经足细胞自噬途径治疗SLE的关键活性成分4种,核心靶点基因5个(STAT1、PIK3CG、MAPK1、PRKCA、CJA1);富集分析显示可能涉及AGERAGE、JAK/STAT、EGFR、PI3K/Akt等信号通路。分子对接结果显示关键活性物质和核心靶点均有较好的结合活性。其中STAT1是结合活性最好的靶蛋白。临床试验证实健脾滋肾方能够显著降低血清中p-JAK1/JAK1及p-STAT1/STAT1、LC3II/LC3I蛋白表达水平(P<0.05或P<0.01),升高p62蛋白表达水平(P<0.05),降低尿液中nephrin、synaptopodin水平(P<0.05)。结论健脾滋肾方经足细胞自噬治疗SLE具有多成分、多靶点、多通路协同作用的特点,其可能通过槲皮素、山奈酚、β-谷甾醇、异鼠李素等关键活性成分作用于STAT1靶基因,抑制JAK/STAT通路相关基因表达,调控自噬减轻SLE足细胞损伤。

膜性肾病(MN)是临床上表现为肾病综合征的主要病理类型之一,包括一组临床和病理相似的肾脏疾病,特征性的病理改变是肾小球毛细血管基底膜弥漫性增厚,肾小球毛细血管袢上皮侧可见大量排列紧密、规则的免疫复合物沉积,是导致成人肾病综合... 详细信息

膜性肾病(MN)是临床上表现为肾病综合征的主要病理类型之一,包括一组临床和病理相似的肾脏疾病,特征性的病理改变是肾小球毛细血管基底膜弥漫性增厚,肾小球毛细血管袢上皮侧可见大量排列紧密、规则的免疫复合物沉积,是导致成人肾病综合征的一个常见原因。MN起病比较隐匿,早诊断、早治疗意义重大,依据病因可分为特发性膜性肾病(IMN)和继发性膜性肾病(SMN)。多种自身抗体如抗M型磷脂酶A2受体(PLA2R)抗体、抗Ⅰ型血小板反应蛋白7A域(THSD7A)抗体等证实为IMN、SMN或其他肾小球疾病诊断、鉴别诊断、疾病活动及预后的重要依据。近年来,不断发现MN相关新的生物标志物,已陆续鉴定足细胞靶抗原如神经表皮生长因子样1蛋白、信号素3B、原钙黏蛋白7、丝氨酸蛋白酶HTRA1、外泌素1/外泌素2、神经细胞黏附分子1等与MN相关,并分别具有独特的生物学意义,尤其对于PLA2R和THSD7A阴性的MN疾病诊断以及疾病预测具有重要临床价值。本文主要对膜性肾病相关靶抗原及自身抗体检测的临床意义进行综述。

为深入推进黄河流域环境风险防治,实现黄河流域高质量发展,利用大气污染、水污染、碳排放表征黄河流域环境风险因素,采用空间核密度方法构建核函数进行密度平滑处理,分析环境风险因素空间集聚态势及演化特征;采用考虑空间依赖性的空间自回归模型剖析多维因素对环境风险因素的影响。结果表明:大气污染、水污染、碳排放主要集中在黄河流域中下游城市,环境风险防治区域明显;产业结构优化升级及企业绿色技术创新可降低环境风险因素,但节能环保支出不合理会导致环境风险因素升高;经济水平和人口密度与风险因素之间存在倒U型曲线关系。从长远发展战略看,应该以区域协同治理、减污降碳协同治理为战略主导,加强中下游城市协作,优化产业结构,加大行业技术创新投入,实现经济发展模式转型。
