Este estudo tem como objetivo avaliar a melhora da NOA após a intervenção de Tuina utilizando indicadores comportamentais padronizados e investigar os mecanismos de Tuina para OA e a associação entre músculo esquelético e OA. Ao contrário das terapias farmacológicas e cirúrgicas, Tuina tem um efeito regulatório positivo sobre os sistemas motor, imunológico e endócrino. Tuina pode aliviar a inflamação e dor produzida pela doença, agindo em diferentes alvos. Por exemplo, ao regular a via TLR4 e o miRNA, pod...

A osteoartrite do joelho (OA) é uma osteoartrite degenerativa comum, caracterizada por dor crônica e incapacidade, e a OA relativamente grave levará a danos estruturais irreversíveis na articulação1. A alta prevalência global de OA de joelho tornou-se um grande desafio de saúde pública mundial 2,3, o que prejudica seriamente a qualidade de vida dos pacientes 4,5. Estudos mostram que a OA afeta mais de 260 milhões de pessoas em todo o mundo6. Com o envelhecimento da população, a taxa de prevalência total de OA na China chega a 17,0% acima dos 40 anos, o que sobrecarrega as famílias das pessoas afetadas 7,8.
De acordo com a medicina chinesa, a OA pertence à categoria de "paralisia"9, e o Clássico de Medicina Interna do Imperador Amarelo associa tendões, ossos e carne à paralisia. Assim, precisamos prestar atenção à conexão entre a cartilagem, músculo, sinóvia, bem como outros tecidos ao redor da articulação do joelho na OA. Na medicina moderna, tanto a inflamação muscular quanto a óssea, que são os principais componentes da homeostase imunológica da artrite, impulsionam a progressão da dor por KOA. No entanto, a maioria dos estudos se concentra na inflamação da cartilagem e na inflamação sinovial nas articulações ósseas, e há uma escassez de artigos examinando fenômenos inflamatórios na musculatura esquelética. Portanto, mais pesquisas sobre o papel do músculo esquelético na inflamação são necessárias para obter uma compreensão mais abrangente da OA e fornecer ideias para modalidades de tratamento mais eficazes. Em uma revisão da literatura, observamos que a inibição do fator imuno-relacionado ao ligante de morte programada 1 (PD-L1) exacerbou a progressão da OA10,11 e que houve expressão diferencial de IL-15 e FOXO1 no músculo esquelético de pacientes com OA 12, bem como inflamação muscular esquelética significativa em pacientes com OA terminal o que também esteve associado a alterações na marcha. Tem sido demonstrado que o músculo esquelético também pode secretar fatores intimamente relacionados à imunidade inflamatória, como a IL-6, e que o TNF-α também está intimamente relacionado à via PD-L1 e à OA13,14,15.
Atualmente, os tratamentos disponíveis para OA incluem controle de peso, exercícios, medicação e cirurgia, que geralmente incluem injeções intra-articulares, medicação analgésica, cirurgia artroscópica e osteotomia periprotética do joelho16. Atualmente, a progressão da doença de OA não pode ser completamente interrompida ou revertida e, sem uma compreensão clara dos complexos mecanismos subjacentes à dor em OQ, os pacientes com OA estão em risco de uso excessivo de medicamentos analgésicos e alta incidência de efeitos colaterais8. A maioria das estratégias de tratamento é eficaz apenas por curtos períodos e se concentra apenas no alívio temporário dos sintomas e não na patogênese da doença. Portanto, a dor em OA permanece uma prioridade e um desafio para o tratamento, representando um sério desafio clínico. No entanto, Tuina pode estimular diretamente os músculos esqueléticos ao redor da articulação afetada no tratamento com KOA e pode fornecer alguns benefícios. Combinado com a descrição anterior, é a terapia ideal para estudar o papel do tecido muscular esquelético na OA de joelhos, e esclarecer o papel do tecido muscular esquelético na inflamação também pode fornecer melhor suporte teórico para Tuina de OA.
Estudos têm demonstrado que a massoterapia, a terapia manipulativa osteopática e a manipulação da coluna vertebral podem ajudar a aliviar a dor e restaurar a função corporal17,18. Essas manipulações podem atuar na inflamação local e aliviar espasmos e analgesia por meio de ação mecânica externa. Podem aliviar a dor após artroplastia total do joelho, reduzir o uso de analgésicos, promover a recuperação pós-operatória e melhorar o equilíbrio biomecânico19. A massagem sueca é viável no tratamento da osteoartrite e pode reduzir o estresse e melhorar a qualidade de vida20. O efeito terapêutico de Tuina sobre a OA foi precedido por alguns estudos.
Neste experimento, nossa equipe explorará se a expressão de PD-L1 e fatores inflamatórios relacionados no músculo esquelético podem induzir KOA e promover seu desenvolvimento com base no modelo de KOA induzido por MIA em ratos. Tuina também será implementado para ver se pode aliviar os sintomas de KOA causados pelo aumento da expressão do fator inflamatório. Tuina será combinada com inibição de PD-L1 para demonstrar a associação entre a via PD-1 mediada por Tuina na inflamação do músculo esquelético que afeta o desenvolvimento de OA e dor, lançando as bases para estudos multiníveis adicionais sobre os mecanismos terapêuticos da intervenção de Tuina em OA.
Em resumo, este artigo descreve a investigação e elaboração dos mecanismos de inflamação do músculo esquelético no desenvolvimento de OA e sua dor, bem como os efeitos terapêuticos de Tuina sobre OA, sob a perspectiva da expressão de fatores imune-inflamatórios, combinados com indicadores comportamentais, para fornecer evidências modernas de pesquisa para a teoria do "desequilíbrio de tendão e osso" na medicina tradicional chinesa.

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

A osteoartrite do joelho (OA), uma doença articular degenerativa comum, é caracterizada por dor crônica e incapacidade, que podem evoluir para danos estruturais irreparáveis da articulação. Investigações sobre a ligação entre cartilagem articular, músculos, sinóvia e outros tecidos ao redor da articulação do joelho na OA são de grande importância. Atualmente, o manejo da OA inclui modificações no estilo de vida, exercícios, medicamentos e intervenções cirúrgicas; no entanto, a elucidação dos intrincados mecanismos subjacentes à dor relacionada à OA ainda é escassa. Consequentemente, a dor em OA de joelho continua sendo um desafio clínico fundamental e uma prioridade terapêutica. Tuina foi encontrado para ter um efeito regulador sobre os sistemas motor, imunológico, e endócrino, levando a exploração de se Tuina poderia aliviar os sintomas de KOA, causados pela upregulation de fatores inflamatórios, e ainda, se os fatores inflamatórios no músculo esquelético podem aumentar a progressão de KOA.
Foram randomizados 32 ratos machos Sprague Dawley (SD) (180-220 g) em quatro grupos de oito animais cada: antiPD-L1+Tuina (grupo A), modelo (grupo B), Tuina (grupo C) e cirurgia simulada (grupo D). Para os grupos A, B e C, injetamos 25 μL de solução de monoiodoacetato de sódio (MIA) (4 mg de MIA diluídos em 25 μL de solução salina estéril) na cavidade articular do joelho direito e, para o grupo D, a mesma quantidade de soro fisiológico estéril foi injetada. Todos os grupos foram avaliados por meio de testes de menor a maior estresse (limiar mecânico de retirada da pata, latência térmica de retirada da pata, edema da articulação do joelho direito, escore de Lequesne MG, temperatura cutânea) antes da injeção e 2, 9 e 16 dias após a injeção.

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.

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.
