脊髓损伤(SCI)是导致严重病患的主要原因,常引起长期残疾。我们比较了粒细胞集落刺激因子(G-CSF)给药后与对照组的治疗效果。通过检索MEDLINE、Embase和Cochrane图书馆数据库,共获得222条记录,其中六项研究符合纳入标准。采用固定效应模型和随机效应模型,对各项结局指标计算比值比(OR)和均数差(MD),并提供95%置信区间(CI)。合并分析结果显示,在不完全性SCI患者中,使用G-CSF治疗3个月后,美国脊髓损伤协会(ASIA)运动评分显著提高(MD = 0.57 [95% CI = 0.04, 1.10],I 2= 63.84%p= 0.036),6个月(MD = 4.18 [95% CI = 0.55, 7.80],I 2= 98.75%p= 0.024),6个月时ASIA针刺觉评分的变化(MD = 3.38 [95% CI = 1.48, 5.28],I 2= 89.78%p< 0.001),以及在6个月时脊髓独立性测量(SCIM)III评分升高(MD = 3.27 [95% CI = 1.13, 5.41],I 2= 91.86%p= 0.003)。G-CSF 导致的不良事件多于非 MP 对照组(OR = 1.44 [95% CI = 0.38, 2.50],I 2= 0%p= 0.008),但少于MP对照组(OR = -4.2 [95% CI = -5.72, -2.68],I 2= 0%p< 0.001)。与基线相比,给予G-CSF后全身白细胞计数增加(MD = 3.57 [95% CI = 2.79, 4.35],I 2= 55.06%p< 0.001)。G-CSF 在 3 个月时对 ASIA 损伤量表评分的提升未达到统计学意义(MD = 0.48 [95% CI = -0.33, 1.28],I 2= 0%p= 0.246)或在6个月时(MD = 1.84 [95% CI = -0.10, 3.79],I 2= 50.09%p= 0.063)。这六项研究的荟萃分析表明,与对照组相比,使用G-CSF治疗不完全性脊髓损伤(SCI)可能会改善神经功能预后。然而,由于样本量较小且研究间存在异质性,结果受到一定限制。未来需要开展更为严谨的前瞻性、随机对照研究,以进一步明确G-CSF的安全性和有效性。

Regulation of Hematopoietic Stem Cells

All blood and immune cells are produced from the multipotent hematopoietic stem cells (HSCs) by the process of hematopoiesis. However, they all have a limited life span. In addition, many are depleted in immune surveillance or combatting an injury or infection. This makes blood one of the most regenerative tissues. Hematopoiesis helps replenish these blood and immune cells, restoring the body's normal functioning. However, overproduction of blood and immune cells can make them cancerous or...

Spinal Cord Injury ll: Pathophysiology

Spinal cord injury progresses through two interconnected phases: primary injury and secondary injury.Primary InjuryPrimary injury happens at the moment of trauma and involves immediate mechanical damage to the spinal cord.Compression happens when broken vertebrae, herniated discs, or accumulating blood (such as a hematoma) press directly against the spinal cord, distorting its normal shape and function. In cases of contusion, the cord is bruised by a blunt force (like penetrating injuries or...

Secondary Spinal Cord Injury llI: Pathophysiology

Early Ischemia and Ionic ImbalanceWithin minutes of spinal cord injury, a secondary cascade begins, progressing over hours to weeks. Vascular damage reduces blood flow, causing ischemia and mitochondrial dysfunction. ATP depletion leads to ion pump failure, membrane depolarization, sodium influx, potassium efflux, and water accumulation, resulting in cellular swelling. Increased intracellular calcium further disrupts mitochondria and accelerates cellular injury.Excitotoxicity and Neuronal...
