Osteoporosis Management in Rats Through Lingnan Fire-Needle Therapy

Lingnan fire-needle therapy has a profound historical background. Records on fire needles and needling methods can be traced back to Huangdi Neijing. Modern acupuncturists Situ Bell and Zhang Jiawei combined Lingnan&#39;s climate and the physical characteristics of its people to create Lingnan fire-needle therapy3. Lin Guohua summarized Lingnan Fire-Needle therapy, as warming, dredging, tonifying, clearing, and eliminating, with warming as the essence24.

Chinese medicine believes that factors such as climate and environment can affect a person&#39;s physique, which in turn affects the occurrence and development of diseases. The Lingnan region of China, mainly including Guangdong, Guangxi, and Hainan Island, is located in the tropical monsoon climate region. As a result, people living in this region for a long time are prone to a form of spleen deficiency. In some cases, it spreads to the kidney and liver, leading to the prevalence of osteoporosis1. The spleen and stomach function in transporting and absorbing water and grains, which are the source of qi and blood biochemistry, while the liver helps maintain the marrows. So, bone nutrition relies on the supply of the spleen, stomach, and liver. In Chinese medicine, the kidney is capable of generating marrow and strengthening bones, and its vitality directly affects the strength and function of bones. Therefore, kidney deficiency is directly related to osteoporosis. According to TCM, liver (Gan)-kidney (Shen) deficiency and lack of essence (Jing) are the underlying causes. In some cases, malnutrition may occur due to a spleen (Pi) and stomach (Wei) deficiency or an imbalance of the two. That is, the deficiency of the liver (Gan), kidneys (Shen), spleen (Pi), and stomach (Wei) are the root causes, while external qi (Xie qi) blocks meridians and damages bones and muscles. According to the World Health Organization (WHO), OP is a medical condition characterized by low bone mass and tissue deterioration2, which is a serious concern for the elderly. The selection of appropriate interventions is crucial for the prevention and treatment of osteoporosis.
Modern acupuncturists have developed a unique Lingnan characteristic of fire-needling therapy by combining the climate of Lingnan and the physical characteristics of Lingnan people3. Fire needle therapy is a kind of treatment method in which special needles are burned red and quickly pierced into specific parts or acupoints of the human body to treat various ailments. This method is widely used in skin diseases, musculoskeletal and joint diseases, neurological diseases, and other systemic diseases and shows good efficacy4. The treatment of osteoporosis with fire needles has been used in clinics for a long time, and it has a better curative effect than simple acupuncture or oral administration of traditional Chinese medicine5,6,7. The Lingnan fire-needle therapy integrates acupuncture, three-edged needles, and scarring moxibustion. It can improve the qi and blood circulation in the meridians while warming the kidney. This treatment can address both blood stasis and kidney (Shen) deficiency, which contribute to the pathogenesis of OP in TCM. What&#39;s more, it has the advantages of being low cost, having quick effects, a short treatment period, and being safe. However, there is a lack of research on its mechanism. This paper introduces a specific procedure of Lingnan Fire-Needle in osteoporosis model rats and provides a methodological basis for conducting related basic research.

operation procedure and precautions of lingnan fire-needle therapy in osteoporosis model rats

Compared to filiform needle therapy, fire-needle therapy has both the stimulation of needles and the warming effect of heat, making it have unexpected effects on some chronic diseases and incurable diseases. Osteoporosis (OP) has a high incidence in postmenopausal women and middle-aged and elderly men, and the treatment cycle is long. According to Traditional Chinese Medicine (TCM), Lingnan fire-needle therapy has shown potential in treating osteoporosis. However, there is still a long way to go before it can be widely used. This article focuses on the application of Lingnan fire-needle therapy in the intervention of OP in rats. It covers the selection of needle tools, acupuncture point selection, positioning of rats' bodies, and fixation methods. We also outline the steps and precautions to be taken during and after needling with fire needles. The experiment was done with three groups: a normal group, a model group, and a fire-needle group, each containing 10 rats. The rats in the fire-needle group were treated with fire-needle intervention for six sessions. After the intervention period, we collected femoral specimens and performed micro-CT scans. The results suggest that fire needling can enhance bone morphology and mineral density in OP rats. This information can serve as a methodological basis for conducting basic research on fire-needle therapy.

The data in Table 1 shows that compared with the normal group, the thickness of trabecular bone (Tb.Th), the number of trabecular bone (Tb.N) and the static parameter bone volume fraction of trabecular bone (BV/TV) in the model group were all significantly reduced (p &#60;0.05), and the separation of trabecular bone (Tb.Sp) was elevated (p &#60;0.05); indicating that the bone structure of trabecular bone in trabecular bone-enriched areas of the femoral epiphysis of the rat was significantly disrupted aft...
