    摘要:

    目的 建立评价肾虚血瘀型Kümmell病(Kümmell disease, KD)的动物模型以探究其潜在治疗靶点与作用机制。方法 将24只SD大鼠随机分为假手术组、对照组与模型组。模型组行卵巢切除术诱导肾虚状态,2个月后于尾椎制造骨缺损模型,施加4周机械应力。骨缺损术后1周皮下注射盐酸肾上腺素诱导血瘀证。对照组行卵巢切除与骨缺损术,注射生理盐水。监测各组体温、体重、摄食饮水量及舌象变化。建模结束后进行行为学观察,并行影像学、血液流变学及组织病理学检测。结果 模型组较假手术组及对照组呈现体温升高、体重减轻、摄食减少、舌质紫暗伴舌下络脉迂曲、毛发枯槁、精神萎靡及运动障碍。影像学显示模型组皮质变薄、骨小梁稀疏断裂、椎体内真空裂隙征。血液学检测提示模型组全血黏度(低/中/高切)及血浆黏度显著升高,纤维蛋白原上升,凝血酶时间、凝血酶原时间及活化部分凝血活酶时间缩短;血清钙磷降低,骨转换标志物升高;甲状腺激素及雌二醇水平较假手术组显著降低。组织学显示模型组骨小梁结构破坏,新生骨低于对照组。结论 卵巢切除联合肾上腺素诱导及机械应力干预可成功构建肾虚血瘀证候的KD大鼠模型。

    Abstract:

    Objective To develop an animal model for Kümmell"s disease (KD) characterized by kidney deficiency and blood stasis, thereby facilitating the exploration of therapeutic targets and underlying mechanisms. Methods Twenty-four Sprague-Dawley rats were randomly allocated into three groups: sham operation, control, and model. The model group underwent ovariectomy to induce kidney deficiency, followed two months later by coccygeal bone defect creation and application of mechanical stress for four weeks. One week post-bone defect surgery, subcutaneous adrenaline hydrochloride injections were administered to induce blood stasis. The control group received ovariectomy and bone defect surgeries with normal saline injections. Throughout the experiment, body temperature, weight, food and water consumption, and tongue characteristics were monitored. Post-modeling, behavioral assessments, imaging analyses, hemorheological tests, and histopathological examinations were conducted. Results Compared to the sham and control groups, the model group exhibited elevated body temperatures, weight loss, reduced food intake, purple tongues with tortuous sublingual veins, dry fur, lethargy, and movement disturbances. Imaging revealed cortical thinning, sparse and fractured trabeculae, and vacuum cleft signs in the vertebral bodies of the model group. Hematologically, significant increases in whole blood viscosity (at low, medium, and high shears) and plasma viscosity, elevated fibrinogen levels, and shortened thrombin time, prothrombin time, and activated partial thromboplastin time were observed. Serum calcium and phosphorus levels decreased, while bone turnover markers increased. Thyroid hormone and estradiol levels were notably lower in the model group relative to the sham group. Histologically, the model group displayed disrupted trabecular architecture and reduced new bone compared to control. Conclusions Combining ovariectomy, adrenaline induction, and mechanical stress successfully establishes a rat model of KD with concurrent kidney deficiency and blood stasis syndrome, providing a platform for investigating therapeutic strategies and pathophysiological mechanisms.
