文题释义:
人脐血衍生物:指从人脐血中提取的多种生物活性物质和细胞成分,主要包括单个核细胞、间充质干细胞和造血细胞,以及各种生长因子和抗炎/免疫调节因子,还有血液衍生因子富血小板血浆。这些衍生物展现出多样化且重要的生物学功能,如促进细胞增殖、分化、迁移和免疫调节等,在血液疾病治疗、再生医学、组织修复和免疫调节等领域具有广泛的应用前景。结果与结论:①子宫组织大体观、苏木精-伊红染色和Masson染色结果:假手术组结构完整,内膜厚度适中,血管结构清晰。与假手术组相比,模型组子宫萎缩,结构不完整,内膜厚度、腺体数量明显减少,血管结构紊乱,纤维化增加;与模型组相比,经人脐血衍生物治疗后,子宫大小、结构、内膜厚度均有所恢复(均P < 0.01),并且纤维化均减轻,其中以人脐血单个核细胞组恢复最为明显。在腺体数量增加方面,以人脐血富血小板血浆组效果最为显著(P < 0.000 1)。②子宫组织免疫组化与免疫荧光结果显示,与假手术组相比,模型组细胞增殖相关指标角蛋白9、波形蛋白,内膜容受性相关指标白血病抑制因子、整合素αγβ3,血小板内皮细胞黏附分子、碱性成纤维细胞生长因子、血管内皮生长因子表达均降低(均P < 0.05)。与模型组相比,经人脐血衍生物治疗后以上指标均有显著性升高,人脐血衍生物各组比较:角蛋白9、血管内皮生长因子蛋白:人脐血单个核细胞组>人脐血间充质干细胞组>人脐血富血小板血浆组;波形蛋白、白血病抑制因子蛋白:人脐血间充质干细胞组>人脐血单个核细胞组>人脐血富血小板血浆组;整合素αγβ3蛋白:人脐血富血小板血浆组>人脐血间充质干细胞组>人脐血单个核细胞组;血小板内皮细胞黏附分子蛋白:人脐血富血小板血浆组>人脐血单个核细胞组>人脐血间充质干细胞组;碱性成纤维细胞生长因子蛋白:人脐血单个核细胞组>人脐血富血小板血浆组>人脐血间充质干细胞组。③Western blot检测显示,与假手术组相比,模型组白细胞介素6、白细胞介素1β和肿瘤坏死因子α蛋白表达水平显著升高(均P < 0.001),经人脐血衍生物治疗后上述指标均降低(均P < 0.05)。④ELISA检测显示,与假手术组相比,模型组抗缪勒氏管激素、雌二醇、孕酮水平降低,促卵泡生成素、促黄体生成素水平增加(除促黄体生成素外,均P < 0.05)。经人脐血衍生物治疗后,性激素和抗缪勒氏管激素水平有一定程度恢复。⑤生育力实验显示,与假手术组相比,模型组受孕时间有所增加,产仔数明显降低(均P < 0.05)。经人脐血衍生物治疗后,3组产仔数均有所增加(P < 0.05),组间比较尚未发现明显差异。此研究初步表明人脐血单个核细胞对薄型子宫内膜有一定治疗效果,且人脐血富血小板血浆、人脐血单个核细胞和人脐血间充质干细胞分别在改善薄型子宫内膜再生功能、内膜容受性、血管生成、炎症调控及妊娠结局方面具有不同的优势与差异。

0.2 mL,维持2 min后,继续宫腔注射0.3 mL,维持3 min,共维持5 min。维持后需抽出剩余未吸收液体,对于注射体积分数95%乙醇的大鼠,需换生理盐水冲洗宫腔2次。然后,根据分组缓慢维持再灌注PBS或脐血衍生物0.5 mL,见表1。另一侧子宫操作相同。注射完成后退出注射器针头,用医用胶迅速封闭针头穿刺孔,防止外渗。操作过程尽量不移动注射器针头,避免子宫穿孔。最后恢复子宫解剖结构,依次缝合关腹。术后注意保温,术后当日在大鼠饮用水中放入阿莫西林胶囊0.25 g,连续3 d,预防术后感染。严密观察大鼠行为有无异常。
1.4.6 体质量与动情周期的测定 自7-9周龄SD大鼠被引入动物房缓冲间后,从第2日起,直到大鼠连续3个动情周期保持规律为止,每日上午8:00-9:00称体质量。小棉签蘸取阴道分泌物涂抹在载玻片上,室温下自然干燥后以亚甲蓝溶液染色10-12 min,蒸馏水缓慢冲洗染液。光学显微镜下观察阴道脱落细胞,依据脱落细胞形态确定具体的动情周期时期。

文题释义:#br#
人脐血衍生物:指从人脐血中提取的多种生物活性物质和细胞成分,主要包括单个核细胞、间充质干细胞和造血细胞,以及各种生长因子和抗炎/免疫调节因子,还有血液衍生因子富血小板血浆。这些衍生物展现出多样化且重要的生物学功能,如促进细胞增殖、分化、迁移和免疫调节等,在血液疾病治疗、再生医学、组织修复和免疫调节等领域具有广泛的应用前景。
薄型子宫内膜:是指在特定生理或病理情况下,子宫内膜厚度相对较薄,无法满足正常妊娠的必要条件,主要表现为细胞增殖不足和功能失衡,是导致女性月经异常、不孕症和反复流产的重要因素,能够影响子宫内膜的耐受性,进而降低胚胎的着床率和临床妊娠率,同时与辅助生殖治疗的预后质量下降相关。

根据世界卫生组织的统计,全球约有1.86亿人无法生育,占育龄人口的15%-20%。然而,妊娠的建立和维持在很大程度上取决于子宫内膜的功能。薄型子宫内膜通常对生长刺激无反应,是取消胚胎移植的重要指标。鉴于子宫内膜在育龄期女性和孕产妇健康及生殖中的重要作用,维持其生理结构、消除缺陷并在受伤后恢复其正常功能至关重要。本研究旨在探索和对比3种脐血衍生物(hUCB-PRP、hUCB-MSCs 和 hUCB-MNCs)治疗薄型子宫内膜的效果及对妊娠结局的影响,以期为薄型子宫内膜的临床应用提供更科学的依据。
