Exploring the mechanism of Buyang Huanwu decoction in the treatment of lumbar disc herniation based on network pharmacology and molecular docking

Buyang Huanwu decoction (BYHWD), as one of the traditional Chinese medicine formulas, is widely used in the clinical treatment of lumbar disc herniation (LDH) with curative effect. It has the characteristics of multi-component, multi-target, and mutual synergy, but the mechanism of action is often unclear. It needs some research to explore the molecular mechanism of BYHWD in the treatment of LDH based on network pharmacology and molecular docking. Screen the active compounds of BYHWD and predict drug-related gene/protein targets, which could determine the specific target of BYHWD in the treatment of LDH. Construct the “Drugs-Compounds-Targets” network and search for the core targets. Use Gene Ontology functional enrichment analysis, Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis, and molecular docking verification to explore the possible molecular mechanism. Eighty-two effective compounds and 666 targets of BYHWD, 187 targets for LDH treatment, and 20 core candidate targets were excavated. A total of 3414 entries were identified by Gene Ontology enrichment analysis, 173 related signal pathways were identified by Kyoto Encyclopedia of Genes and Genomes enrichment analysis, and 5 core compounds were identified by molecular docking, which had a good affinity with core genes STAT3, JUN, AKT1, MAPK1, RELA, and PIK3CA. BYHWD may play the role of analgesic and improving function by synergistic anti-inflammatory and analgesic compounds, regulating cell metabolic differentiation, regulating immunity, and anticoagulation. BYHWD in the treatment of LDH may play a role in analgesia and improve function through multiple signaling pathways, including PI3K-Akt, mitogen-activated protein kinase, tumor necrosis factor, and interleukin-17. The PI3K-Akt signaling may be one of the key mechanisms.

中性粒细胞异常增殖相关的BCR/ABL-慢性白血病的临床特征

目的:探讨与中性粒细胞异常增殖相关的BCR/ABL-慢性白血病的临床特征.方法:报告3例不同类型与中性粒细胞异常增殖相关的BCR/ABL-慢性白血病并结合文献进行讨论.结果:3例均为老年男性,表现为以中性粒细胞为主的白细胞异常增多、BCR/ABL融合基因阴性.例1诊断为慢性中性粒细胞白血病(CNL),脾大,外周血以成熟中性粒细胞增高为特征,胞浆内中毒颗粒易见,无明显病态造血,中性粒细胞碱性磷酸酶(NAP)染色强阳性,骨髓粒系增生明显活跃.例2诊断为不典型慢性髓细胞白血病(aCML),血涂片示不成熟粒细胞比例增高伴粒系病态造血,尤其核染色质异常浓聚更为明显,骨髓象表现为髓系增生和病态造血,原始细胞轻度增多.例3诊断为慢性粒单核细胞白血病(CMML),外周血成熟单核细胞数量和比例异常偏高,粒系病态如核分叶过多、环状核和假性Pelger-Huet畸形等易见,骨髓髓系增生明显活跃伴病态造血,无原始细胞增多.结论:中性粒细胞异常增殖相关的BCR/ABL-慢性白血病较为少见,易于误诊,细胞形态学特征是诊断BCR/ABL-慢性白血病的基础.临床表现、多种实验室检查结果尤其是分子生物学等有助于正确诊断这类疾病.
