本研究旨在通过使用标准化的行为指标评估推拿干预后 KOA 的改善情况，并探讨推拿治疗 KOA 的机制以及骨骼肌与 KOA 的关联。与药物和手术治疗不同，推拿对运动、免疫和内分泌系统有积极的调节作用。推拿可以通过作用于不同的靶点来缓解疾病引起的炎症和疼痛。例如，通过调节TLR4通路和miRNA，它可以抑制神经胶质细胞的活化，调节脑功能改变，调节下游炎性细胞因子，抑制外周炎症<sup class="x...

膝骨关节炎（KOA）是一种常见的退行性骨关节炎，以慢性疼痛和残疾为特征，相对严重的KOA会导致关节不可逆的结构性损伤1。KOA 的全球高患病率已成为全球公共卫生的重大挑战2,3，严重损害患者的生活质量 4,5。研究表明，KOA 影响着全球超过 2.6 亿人6。随着人口老龄化，我国40岁以上KOA总患病率高达17.0%，给受影响者的家庭带来了沉重的负担7,8。
根据中医的说法，KOA属于“麻痹”的范畴9，《黄帝内科经》将肌腱、骨骼和肉与麻痹联系在一起。因此，我们需要注意 KOA 中软骨、肌肉、滑膜以及膝关节周围其他组织之间的联系。在现代医学中，肌肉和骨骼炎症是关节炎免疫稳态的主要组成部分，它们推动了 KOA 疼痛的进展。然而，大多数研究集中在骨关节的软骨炎症和滑膜炎症上，并且缺乏研究骨骼肌炎症现象的文章。因此，需要对骨骼肌在炎症中的作用进行更多研究，以更全面地了解KOA，并为更有效的治疗方式提供思路。在文献综述中，我们发现抑制免疫相关因子程序性死亡配体 1 （PD-L1） 加剧了 KOA 10,11 的进展，并且 IL-15 和 FOXO1 在 KOA12 患者的骨骼肌中存在差异表达，以及终末期 KOA 患者骨骼肌炎症明显， 这也与步态的变化有关。研究表明，骨骼肌还可以分泌与炎症免疫密切相关的因子，如IL-6，TNF-α也与PD-L1通路和KOA13,14,15密切相关。
目前，KOA 的可用治疗方法包括体重控制、运动、药物治疗和手术，通常包括关节内注射、镇痛药物、关节镜手术和膝关节假体周围截骨术16。目前，KOA疾病的进展无法完全停止或逆转，如果不清楚地了解KOA疼痛的复杂机制，KOA患者有过度使用镇痛药物和高副作用发生率的风险8。大多数治疗策略仅在短期内有效，并且仅关注症状的暂时缓解，而不是疾病的发病机制。因此，KOA疼痛仍然是治疗的重点和挑战，构成了严峻的临床挑战。然而，在KOA治疗中，推拿可以直接刺激患处关节周围的骨骼肌，并能提供一些好处。结合前文所述，是研究骨骼肌组织在KOA中的作用的理想疗法，阐明骨骼肌组织在炎症中的作用也可以为KOA推拿提供更好的理论支持。
研究表明，按摩疗法、整骨手法疗法和脊柱推拿可以帮助缓解疼痛和恢复身体功能17,18。这些操作可以作用于局部炎症，并通过外部机械作用缓解痉挛和镇痛。它们可以缓解全膝关节置换术后的疼痛，减少镇痛药物的使用，促进术后恢复，改善生物力学平衡19。瑞典式按摩在治疗骨关节炎方面是可行的，可以减轻压力和提高生活质量20.推拿对KOA的治疗效果已经有了一些研究。
在本次实验中，我们团队将基于MIA诱导的大鼠KOA模型，探讨骨骼肌中PD-L1及相关炎症因子的表达是否能诱导KOA并促进其发展。推拿也将实施，看看它是否可以缓解由炎症因子表达增加引起的KOA症状。推拿将与PD-L1抑制相结合，证明推拿介导的PD-1通路在骨骼肌炎症中影响KOA发展和疼痛的关联，为进一步多层次研究推拿干预KOA的治疗机制奠定了基础。
综上所述，本文从免疫-炎症因子表达的角度，结合行为相关指标，阐述了骨骼肌炎症在KOA及其疼痛发展中的机制，以及推拿对KOA的治疗效果，以期为中医“筋骨失衡”理论提供现代研究证据。

tuina intervention in sodium monoiodoacetate injection-induced rat model of knee osteoarthritis

膝骨关节炎 （KOA） 是一种常见的退行性关节疾病，其特征是慢性疼痛和残疾，可发展为无法修复的关节结构损伤。研究关节软骨、肌肉、滑膜和 KOA 膝关节周围其他组织之间的联系非常重要。目前，管理 KOA 包括改变生活方式、运动、药物治疗和手术干预;然而，仍然缺乏对KOA相关疼痛的复杂机制的阐明。因此，KOA疼痛仍然是一个关键的临床挑战和治疗重点。推拿已被发现对运动、免疫和内分泌系统有调节作用，促使人们探索推拿是否可以缓解由炎症因子上调引起的 KOA 症状，以及骨骼肌中的炎症因子是否可以增强 KOA 的进展。
我们将 32 只雄性 Sprague Dawley （SD） 大鼠 （180-220 g） 随机分为四组，每组 8 只动物：抗 PD-L1+推拿（A 组）、模型（B 组）、推拿（C 组）和假手术（D 组）。对于A组、B组和C组，我们将25 μL单碘乙酸钠（MIA）溶液（4 mg MIA稀释在25 μL无菌盐水溶液中稀释）注射到右膝关节腔中，对于D组，注射等量的无菌生理盐水。所有组均在注射前和注射后 2、9 和 16 天使用压力最小到最大的测试（爪子机械戒断阈值、爪子撤出热潜伏期、右膝关节肿胀、Lequesne MG 评分、皮肤温度）进行评估。

Knee osteoarthritis (KOA) is a common degenerative osteoarthritis, characterized by chronic pain and disability, and relatively severe KOA will lead to irreversible structural damage to the joint1. The high global prevalence of KOA has become a major global public health challenge2,3, which seriously impairs the quality of life of patients4,5. Studies have shown that KOA affects more than 260 million people worldwide6. With the aging of the population, the total prevalence rate of KOA in China is as high as 17.0% over the age of 40, which puts a heavy burden on the families of those affected7,8.
According to Chinese medicine, KOA belongs to the category of &#34;paralysis&#34;9, and the Yellow Emperor&#39;s Classic of Internal Medicine associates tendons, bones, and flesh with paralysis. Hence, we need to pay attention to the connection between the cartilage, muscle, synovium, as well as other tissues around the knee joint in KOA. In modern medicine, both muscle and bone inflammation, which are major components of the immune homeostasis of arthritis, drive the progression of KOA pain. However, most studies focus on cartilage inflammation and synovial inflammation in bone joints, and there is a paucity of articles examining inflammatory phenomena in skeletal muscles. Therefore, more research on the role of skeletal muscle in inflammation is needed to gain a more comprehensive understanding of KOA and provide ideas for more effective treatment modalities. In a review of the literature, we found that inhibition of the immune-related factor programmed death ligand 1 (PD-L1) exacerbated the progression of KOA10,11 and that there was differential expression of IL-15 and FOXO1 in the skeletal muscle of patients with KOA12, as well as significant skeletal muscle inflammation in patients with end-stage KOA, which was also associated with changes in gait. It has been shown that the skeletal muscle can also secrete factors closely related to inflammatory immunity such as IL-6, and that TNF-&#945; is also closely related to the PD-L1 pathway and KOA13,14,15.
Currently, available treatments for KOA include weight control, exercise, medication, and surgery, which usually include intra-articular injections, analgesic medication, arthroscopic surgery, and periprosthetic osteotomy of the knee16. Currently, KOA disease progression cannot be completely stopped or reversed, and without a clear understanding of the complex mechanisms underlying KOA pain, KOA patients are at risk for overuse of analgesic medications and a high incidence of side effects8. Most treatment strategies are effective only for short periods and focus only on the temporary relief of symptoms rather than on the pathogenesis of the disease. Therefore, KOA pain remains a priority and a challenge for treatment, posing a serious clinical challenge. However, Tuina can directly stimulate the skeletal muscles around the affected joint in KOA treatment and can provide some benefits. Combined with the previous description, it is the ideal therapy to study the role of skeletal muscle tissue in KOA, and clarifying the role of skeletal muscle tissue in inflammation can also provide better theoretical support for Tuina of KOA.
Studies have shown that massage therapy, osteopathic manipulative therapy, and spinal manipulation can help relieve pain and restore body function17,18. These manipulations can act on local inflammation and relieve spasms and analgesia through external mechanical action. They can relieve pain after total knee arthroplasty, reduce the use of analgesic drugs, promote postoperative recovery, and improve biomechanical balance19. Swedish massage is feasible in the treatment of osteoarthritis and can reduce stress and improve quality of life20. The therapeutic effect of Tuina on KOA has been preceded by certain studies.
In this experiment, our team will explore whether the expression of PD-L1 and related inflammatory factors in skeletal muscle can induce KOA and promote its development based on the MIA-induced KOA model in rats. Tuina will also be implemented to see whether it can alleviate KOA symptoms caused by increased inflammatory factor expression. Tuina will be combined with PD-L1 inhibition to demonstrate the association between Tuina-mediated PD-1 pathway in skeletal muscle inflammation affecting KOA development and pain, laying the foundation for further multi-level studies on the therapeutic mechanisms of Tuina intervention in KOA.
In summary, this paper describes the investigation and elaboration of the mechanisms of skeletal muscle inflammation in the development of KOA and its pain, as well as the therapeutic effects of Tuina on KOA, from the perspective of immune-inflammatory factor expression, combined with behavioral related indicators, to provide modern research evidence for the &#34;imbalance of tendon and bone&#34; theory in traditional Chinese medicine.

单碘乙酸钠注射液诱导膝骨关节炎大鼠模型的推拿干预

We are trying to broaden the views on the research of knee osteoarthritis by introducing the perspective of refocusing on muscle inflammation during the pathological process of the KOA. There is a recent trend in non-pharmacological therapy treating the knee osteoarthritis. Therapy measures of traditional Chinese medicine, such as TNA and acupuncture, are receiving more and more recognition.There is a calling for detailed mechanism in the treatment. Our experiments indicates the possibility of chronic muscle inflammation in the process of knee osteoarthritis. It also points out the possibility of non-pharmacological therapy such as TNA to treat and control it.

Tuina Intervention in Sodium Monoiodoacetate Injection-Induced Rat Model of Knee Osteoarthritis

Knee osteoarthritis (KOA), a common degenerative joint disorder, is characterized by chronic pain and disability, which can progress to irreparable structural damage of the joint. Investigations into the link between articular cartilage, muscles, synovium, and other tissues surrounding the knee joint in KOA are of great importance. Currently, managing KOA includes lifestyle modifications, exercise, medication, and surgical interventions; however, the elucidation of the intricate mechanisms underlying KOA-related pain is still lacking. Consequently, KOA pain remains a key clinical challenge and a therapeutic priority. Tuina has been found to have a regulatory effect on the motor, immune, and endocrine systems, prompting the exploration of whether Tuina could alleviate KOA symptoms, caused by the upregulation of inflammatory factors, and further, if the inflammatory factors in skeletal muscle can augment the progression of KOA.
We randomized 32 male Sprague Dawley (SD) rats (180-220 g) into four groups of eight animals each: antiPD-L1+Tuina (group A), model (group B), Tuina (group C), and sham surgery (group D). For groups A, B, and C, we injected 25 &#181;L of sodium monoiodoacetate (MIA) solution (4 mg MIA diluted in 25 &#181;L of sterile saline solution) into the right knee joint cavity, and for group D, the same amount of sterile physiological saline was injected. All the groups were evaluated using the least to most stressful tests (paw mechanical withdrawal threshold, paw withdrawal thermal latency, swelling of the right knee joint, Lequesne MG score, skin temperature) before injection and 2, 9, and 16 days after injection.

This protocol describes the methods of Tuina intervention in sodium monoiodoacetate injection-induced rat model of knee osteoarthritis (KOA), which provides a reference for the application of Tuina in KOA animal models. This protocol also studies the effective mechanism of Tuina for KOA, and the results will help promote its application.
