Hyaluronan interacts with various receptors in the human body, including CD44, LYVE-1, RHAMM, and TLR2, and is well-known for its analgesic effects when used in intra-articular or ultrasound-guided nerve trunk injections. Studies have shown that hyaluronidase cleaves high molecular weight HA to generate HA35, a low molecular weight fragment with enhanced tissue permeability, capable of binding to HA receptors on cell surfaces to produce broad-spectrum analgesic effects. Methods: Ten patients diagnosed with MPS were treated and assessed in this study. HA35 was administered through injection at a dosage of 100 mg daily for 15 days. Patients evaluated their MPS, overall pain levels, and treatment satisfaction using the Numerical Pain Rating Scale (NPRS), the Global Pain Scale (GPS), and the Treatment Satisfaction Questionnaire for Medication (TSQM 1.4). Follow-up evaluations were performed three months post-treatment to assess the duration of therapeutic effects. Results: Significant improvements were observed in NPRS, GPS, and TSQM scores both during and after the treatment period (P Conclusions: HA35 provides effective and sustained relief from pain associated with MPS, demonstrating a prolonged therapeutic benefit.展开更多

Data sources The data analyzed in this review were mainly from relevant articles without restriction on the publication date reported in PubMed, MedSci, Google scholar. The terms ＂myofasial trigger points＂ and ＂myofacial pain syndrome＂ were used for the literature search. Study selection Original articles with no limitation of research design and critical reviews containing data relevant to myofascial trigger points （MTrPs） and MPS were retrieved, reviewed, analyzed and summarized. Results Myofascial pain syndrome （MPS） is characterized by painful taut band, referred pain, and local response twitch with a prevalence of 85% to 95% of incidence. Several factors link to the etiology of MTrPs, such as the chronic injury and overload of muscles. Other factors, such as certain nutrient and hormone insufficiency, comorbidities, and muscle imbalance may also maintain the MTrP in an active status and induce recurrent pain. The current pathology is that an extra leakage acetylcholine at the neuromuscular junction induces persistent contracture knots, relative to some hypotheses of integration, muscle spindle discharges, spinal segment sensitization, ect. MTrPs can be diagnosed and localized based on a few subjective criteria. Several approaches, including both direct and supplementary treatments, can inactivate MTrPs. Direct treatments are categorized into invasive and conservative. Conclusion This review provides a clear understanding of MTrP pain and introduces the most useful treatment approaches in China.展开更多

Methods:A total of 80 patients with SP were randomized into an observation group and an EA group by the random number table, with 40 cases in each group. The EA group was treated with EA therapy, and the observation group was treated with EA therapy plus Tanbo-plucking the trigger points. After treatment, the visual analog scale (VAS) and Melle scores of the two groups were compared to evaluate the improvement of shoulder pain and functional activity, and meanwhile the clinical efficacy was observed. Results: After treatment, the total effective rate of the observation group was 95.0% and the cure and markedly effective rate was 72.5%. The total effective rate of the EA group was 87.5% and the cure and markedly effective rate was 42.5%. There was no significant difference in the total effective rate between the two groups (P>0.05). The cure and markedly effective rate of the observation group was higher than that of the EA group, and the difference between the two groups was statistically significant (P<0.05). After treatment, the intra-group differences in VAS and Melle scores of both groups were statistically significant (bothP<0.001). The inter-group differences in the changes of the VAS and Melle scores after treatment were statistically significant (bothP<0.001). Conclusion: EA plus Tanbo-plucking the trigger points has a better curative effect than EA therapy alone in the treatment of SP.展开更多

文摘Objective:To investigate the mechanism of trigger point deactivation induced by pressing manipulation in a rat model and to explore its potential regulation of the inflammatory response through the extracellular signal-regulated kinase(ERK)/nuclear factor-κB(NF-κB)pathway.Methods:Fifty male Sprague-Dawley rats were randomly divided into a blank group,a model group,a pressing manipulation group,an ERK agonist group,and a pressing manipulation+ERK agonist group,with 10 rats in each group.Except for the blank group,rats in other groups were used to establish the trigger point rat model using the blunt blow combined with the eccentric exercise method.The pressing manipulation group underwent pressing manipulation intervention at the trigger points.The ERK agonist group received an injection of recombinant human epidermal growth factor via the tail vein.The pressing manipulation+ERK agonist group received interventions from both the pressing manipulation and ERK agonist groups.The pressure pain threshold(PPT)was measured by a mechanical pain threshold detector before and after the intervention.The histological changes were evaluated by hematoxylin-eosin staining after the intervention;the expression levels of ERK,phosphorylated ERK(p-ERK),NF-κB p65(p65),phosphorylated NF-κB p65(p-p65),and phosphorylated NF-κB inhibitor(p-IκB)were detected by Western blotting;the levels of interleukin(IL)-1β,IL-6,and tumor necrosis factor(TNF)-αwere detected by enzyme-linked immunosorbent assay.Results:The PPT increased(P<0.05);the inflammatory cells disappeared;the ratios of p-ERK/ERK,p-p65/p65,and p-IκB/β-actin,also the levels of IL-1β,IL-6,and TNF-αall decreased in the pressing manipulation group after the intervention compared with the model group(P<0.05).The PPT decreased significantly(P<0.05),the inflammatory cell presence increased,and the ratios of p-ERK/ERK and p-p65/p65 were elevated(P<0.05);additionally,the levels of IL-6 and TNF-αwere significantly higher in the pressing manipulation+ERK agonist group compared with the pressing manipulation group(P<0.05).The PPT was significantly lower(P<0.05),the inflammatory cell count was higher,the ratios of p-ERK/ERK and p-IκB/β-actin and the levels of IL-1βand TNF-αwere significantly higher in the ERK agonist group compared with the pressing manipulation+ERK agonist group(P<0.05).Conclusion:Pressing manipulation can effectively alleviate inflammation and pain in trigger point model rats,potentially by inhibiting the ERK/NF-κB signaling pathway.
