【Abstract】 Objective To investigate the effect of massage on quadriceps femoris repair and the expressions of Desmin and α-Actin in rabbits so as to explore the possible molecular mechanisms of massage in repair of muscle injury. Methods Twenty-seven New Zealand white rabbits, weighing (2.0 ± 0.5) kg, were randomly divided into 3 groups: groups A (n=3), B (n=12), and C (n=12). In group A, the rabbits were not treated as controls; in groups B and C, the rabbit models of quadriceps femoris injury were prepared by self-made beater. In group B, no massage therapy was given as nature recovery controls; in group C, RT-N2 intelligent massage device was used for massage therapy at 8 days after injury, at 3 000-3 100 r/min for 15 minutes, every day for 7 days or for 14 days. The quadriceps femoris specimens were taken from 6 rabbits of groups B and C at 14 days and 21 days, respectively. HE staining was employed to detect the histomorphological change. Immunohistochemistry staining and Western blot were used to detect Desmin and α-Actin expressions. The massage therapy effect was evaluated by the histomorphological change and Desmin and α-Actin expressions. Results All rabbits survived to the end of experiment in groups B and C. No histological change was found with regular order of muscle fibers and no connective tissue in group A; obvious tissue necrosis was seen with broken muscular fibers, muscle atrophy, and irregular order in group B; and in group C, the skeletal muscle morphology and muscle atrophy were obviously improved with regenerated muscle fibers when compared with group B. Immunohistochemistry staining showed that the Desmin and α-Actin expressions obviously reduced in groups B and C, which were significantly weaker than that in group A (P lt; 0.05); the Desmin and α-Actin expressions were significantly ber in group C than in group B (P lt; 0.05), and at 21 days than at 14 days in group C (P lt; 0.05). Western blot results showed that the Desmin and α-Actin expressions were significantly higher in group A than in groups B and C (P lt; 0.05), and the expressions were lowest at 14 days in group B. Conclusion The histomorphology and cytoskeletal structure can be significantly improved after massage, which may help to repair muscle injury by up-regulation of Desmin and α-Actin expressions.
ObjectivesTo evaluate the clinical efficacy of massage in the treatment of primary dysmenorrhea (PD).MethodsCNKI, VIP, WanFang Data, CBM, The Cochrane Library, PubMed and EMbase databases were searched to collect randomized controlled trials (RCTs) on the treatment of primary dysmenorrhea from inception to January 6th, 2018. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. RevMan 5.3 software was used for meta-analysis.ResultsA total of 10 RCTs were included, including 758 patients with PD. Meta-analysis results showed that the total effective rate (RR=1.14, 95% CI 1.03 to 1.26, P<0.000 01; RR=1.24, 95% CI 1.15 to 1.34, P<0.000 01) and the dysmenorrhea symptom score (MD=–2.59, 95% CI –3.08 to –2.29, P<0.000 1) in massage group were superior to the control group.ConclusionCurrent evidence suggests that massage for PD has certain advantages. However, due to the limited quality of the included studies, high-quality clinical trials are required to further verify the clinical efficacy of massage in the treatment of primary dysmenorrhea.
ObjectiveTo provide an overview of systematic reviews on the efficacy and safety of massage for the treatment of cervical spondylotic radiculopathy.MethodsCNKI, WanFang Data, VIP, CBM, PubMed, The Cochrane Library and EMbase databases were electronically searched to collect the systematic reviews on the efficacy and safety of massage for the treatment of cervical spondylotic radiculopathy from inception to December 30th, 2018. Two reviewers independently screened the literature and extracted the data, applied the AMSTAR2 scale to evaluate its methodological quality, and GRADE to evaluate the quality of the evidence.ResultsA total of 7 systematic reviews/meta-analysis were included. The AMSTAR2 scale evaluation showed that the quality of the included studies was extremely low. The GRADE evidence grading results showed that the quality of the VAS score outcome index of the two literatures was intermediate, and the quality of the OASCSR outcome index of one literature was intermediate. The quality of the remaining outcome indicators reported is low or very low.ConclusionThe available evidence shows that the efficacy and safety of manual treatment of cervical spondylotic radiculopathy is acceptable, but the overall methodological quality of the systematic review is extremely low, and the quality level of evidence is generally low. The future clinical trials and systematic reviews should be strictly followed. The scientific research design of the medical science provides high-quality evidence and provides reference for clinical practice.
