机制。方法 以骨髓腔注射乳腺癌细胞悬液的方式构建乳腺癌骨转移大鼠模型,将造模成功的雌性大鼠随机分为模型组(灌胃等
体积生理盐水),阳和汤加减低、中、高剂量组(分别灌胃相应药液1.30、2.60、5.20 g/kg,按生药量计),阳和汤加减高剂量+si-RIPK1
组(灌胃相应药液5.20 g/kg,按生药量计;同时尾静脉注射RIPK1小干扰RNA),阳和汤加减高剂量+si-NC组(灌胃相应药液5.20
g/kg,按生药量计;同时尾静脉注射阴性对照小干扰RNA),每组12只;另取12只健康大鼠作为对照组(灌胃等体积生理盐水);每
天给药1次,持续14 d。称定各组大鼠给药前及末次给药后的体重;检测其机械性痛阈值、热痛阈值,观察其胫骨骨破坏情况、病
理变化情况、破骨细胞形成情况;检测其胫骨组织中核因子κB受体活化因子(RANK)及其配体(RANKL)蛋白的阳性表达情况以
及RIPK1、RIPK3、混合谱系激酶结构域样蛋白(MLKL)的磷酸化水平。结果 与对照组比较,模型组大鼠胫骨组织中肿瘤细胞明
显增生并弥散浸润骨髓腔,并可见大片细胞肿瘤性坏死、骨破坏严重、骨皮质变薄、骨小梁受损;其体重(给药前及末次给药后)、机
械性痛阈值、热痛阈值和 RIPK1、RIPK3、MLKL 的磷酸化水平均显著降低,肿瘤体积、胫骨骨破坏面积占比、破骨细胞数量和
RANK、RANKL蛋白阳性表达均显著升高/增多/上调(P<0.05);与模型组比较,阳和汤加减低、中、高剂量组大鼠胫骨组织上述病

ABSTRACT OBJECTIVE To explore the improvement effect and potential mechanism of modified Yanghe decoction on bone
destruction in rats with breast cancer bone metastasis based on the receptor-interacting serine/threonine-protein kinase 1 (RIPK1)/
RIPK3 pathway. METHODS The rat model of breast cancer bone metastasis was established by injecting a suspension of breast
cancer cells into the bone marrow cavity. The rats with successful modeling were randomly divided into a model group (intragastric
administration of equal volume of normal saline), modified Yanghe decoction low-, medium-, and high-dose groups (intragastric
administration of corresponding decoction at 1.30, 2.60 and 5.20 g/kg, calculated by the dosage of crude drug), high-dose
modified Yanghe decoction+si-RIPK1 group (intragastric administration of corresponding decoction at 5.20 g/kg, calculated by the
dosage of crude drug; simultaneous injection of small interfering RNA for RIPK1 via the tail vein), and high-dose modified
Yanghe decoction+si-NC group (intragastric administration of corresponding decoction at 5.20 g/kg, calculated by the dosage of
crude drug; simultaneous injection of small interfering RNA for negative control via the tail vein), with 12 rats in each group.
Another 12 healthy rats were selected as the control group and were given the same volume of normal saline intragastrically, once a
day, for 14 consecutive days. Body weight was measured before administration and at the end of the last administration. The
mechanical pain threshold and thermal pain threshold were measured, and the bone destruction, pathological changes and osteoclast
formation of the tibia were observed. The positive expression of receptor activator of nuclear factor- κB (RANK) and receptor
activator of nuclear factor- κB ligand (RANKL) in the tibial
