Objective: To observe the efficacy of herbal cake-partitioned moxibustion for lumbar disc herniation (LDH) due to kidney deficiency and blood stasis and observe the influence of this method on lumbar functions and inflammatory factors in patients with this condition. Methods: A total of 120 LDH patients who met the inclusion criteria were randomly divided into three groups, including a herbal cake-partitioned moxibustion group, a flour cake-partitioned moxibustion group, and a Western medication group, with 40 patients in each group. The patients in the Western medication group were treated with diflunisal tablets, 0.5 g per dose, 2 doses a day. Those in the herbal cake-partitioned moxibustion group were treated with additional herbal cake-partitioned moxibustion group at Back-Shu Points and Jiaji (EX-B2) Points once a day. Those in the flour cake-partitioned moxibustion group were treated with the same methods as in the herbal cake-partitioned moxibustion group, except that the herbal cake was replaced by a flour cake. All the patients were treated for 10 d. After treatment, the scores of the visual analog scale (VAS) and Japanese Orthopaedic Association (JOA) and the changes of the interleukin (IL)-6, tumor necrosis factor (TNF)-α, and substance P (SP) levels were observed, and the efficacy was evaluated. Results: After treatment, the VAS score and the levels of IL-6, TNF-α, and SP were lower than those before treatment, and the JOA score was higher than that before treatment in the three groups, indicating intra-group statistical significance (P<0.05). The VAS score and the levels of IL-6, TNF-α, and SP of the herbal cake-partitioned moxibustion group were lower than those of the flour cake-partitioned moxibustion group and the Western medication group, while the JOA score of the herbal cake-partitioned moxibustion group was higher than that of the other two groups, indicating inter-group statistical significance (P<0.05). The total effective rate of the herbal cake-partitioned moxibustion group was 92.5%, higher than that of the flour cake-partitioned moxibustion group (80.0%) and the Western medication group (72.5%), indicating inter-group statistical significance (P<0.05). Conclusion: On the basis of Western oral medication, additional herbal cake-partitioned moxibustion can alleviate the pain and improve the lumbar functions in patients with LDH due to kidney deficiency and blood stasis. The efficacy of the integrated method is better than that of either flour cake-partitioned moxibustion or Western medication alone, which may be related to the reduction of serum inflammatory factors.

Objectvie: To observe the law of heat transfer in Zusanli during the process of moxibustion. Methods: Thetemperature change of Zusanli was detected by self-made high-precision temperature sensor while moxibustion on lowerextremities acupoints on six meridians of foot in healthy volunteers for fifteen minutes, the temperature change curve andtemperature change rate curve were drawn with Origin software. Results: Temperature change curve of Zusanli was thebiggest when moxibustion on acupoints in stomach meridian of foot yangming, especially for Shangjuxu acupoint.Whenthe acupoints near the level of Zusanli are moxibusted, the temperature change curve of Zusanli changes obviously.Temperature change rate curves of Zusanli were basically in coincidence when moxibustion on lower extremities acupoints on six meridians of foot, and it had a downward trend. Conclusion: Heat transfer between meridians andacupoints have propagated sensation along channel, regional characteristics, consistency of transmission rate, in theprosess of moxibustion.

ObjectiveTo investigate the effect of capsaicin on cognitive dysfunction in rats with cerebral ischemia-reperfusion and its possible mechanism. MethodTwelve SD male rats were randomly selected as a sham operation group, and the remaining rats were sutured to replicate the model of middle cerebral artery occlusion (MCAO). The successfully modeled rats were divided into a model group, a SB203580 [p38 mitogen-activated protein kinase (p38 MAPK) inhibitor, 1 mg·kg-1] group, capsaicin low- and high-dose (50, 100 mg·kg-1) groups , and anisomycin (p38 MAPK agonist, 2 mg·kg-1) + capsaicin (100 mg·kg-1) group, with 12 rats in each group. After reperfusion and administration, the rats were scored for neurological deficits. Morris water maze and new object recognition experiments were used to test the learning and cognitive abilities of rats. The hematoxylin-eosin (HE) staining was used to observe the pathological changes in the hippocampus of the brain tissue. Immunofluorescence method was used to detect the activation of microglia in the hippocampus. Enzyme-linked immunosorbent assay (ELISA) was used to detect the levels of interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), and prostaglandin E2 (PGE2) inflammatory factors in the brain tissue. Western blot was used to determine the protein expression levels of transient receptor potential vanillin subfamily 1 (TRPV1), p38 MAPK, p-p38 MAPK, and cyclooxygenase-2 (COX-2) in the hippocampal tissue. ResultAs compared with the sham group, the neurological deficit score, escape latency, the number of Iba-1 positive microglia in the hippocampal CA1 area, the IL-1β, TNF-α, and PGE2 levels in the brain tissue, and the p-p38 MAPK/p38 MAPK and COX-2 expression in the hippocampus tissue was significantly increased in the model group (P<0.01). In the model group, the number of crossing the platform position, the novel object discrimination index (DI), and the TRPV1 expression in the hippocampus tissue was significantly reduced (P<0.01), the number of hippocampal nerve cells was reduced, and a large number of inflammatory cells infiltrated. As compared with the model group, the neurological deficit score, escape latency, the number of Iba-1 positive microglia in the hippocampal CA1 area, the IL-1β, TNF-α, and PGE2 levels in the hippocampus tissue, and the p-p38 MAPK/p38 MAPK and COX-2 expression in the hippocampus tissue were significantly reduced in the capsaicin low-dose and high-dose groups (P<0.05,P<0.01). In the capsaicin low-dose and high-dose groups, the number of crossing the platform position, the DI, and the TRPV1 expression in the hippocampus tissue were significantly increased (P<0.05,P<0.01), a small amount of inflammatory cells were infiltrated, and the number of nerve cells was significantly increased. The use of anisomycin, an activator of p38 MAPK, increased the expression of COX-2, and significantly weakened the inhibitory effect of capsaicin on the activation of microglia. ConclusionCapsaicin has a protective effect on the cognitive function of rats with cerebral ischemia-reperfusion, and its mechanism may be related to the inhibition of the activation of p38 MAPK/COX-2 signaling pathway, thereby inhibiting the excessive activation of microglia.
