Journal of Acupuncture and Tuina Science 2021;19(4):307-312
Objective: To observe the efficacy of mild moxibustion combined with functional exercise in the treatment of upper-limb lymphedema after breast cancer surgery and its effect on serum vascular endothelial growth factor C (VEGF-C). Methods: Seventy-eight patients were divided into a control group and an observation group by the random number table method, with 39 cases in each group. The control group received functional exercise and the observation group received mild moxibustion plus functional exercise. The differences in circumference between the two upper limbs, the lymphatic flow of the affected upper limb, the disability of arm, shoulder and hand (DASH) score, the functional assessment of cancer therapy-breast (FACT-B) score and serum VEGF-C level between the two groups were compared before and after treatment. Efficacy was evaluated after treatment. Results: The total effective rate was significantly higher in the observation group than in the control group (P<0.05). The difference in circumference between the two upper limbs of the two groups decreased significantly after treatment (both P<0.05), but it was significantly lower in the observation group than in the control group (P<0.05). The lymphatic flow of the affected upper limb of the two groups increased significantly after treatment (both P<0.05), but it was significantly greater in the observation group than in the control group (P<0.05). The DASH scores of the two groups decreased significantly after treatment (both P<0.05), but it was significantly lower in the observation group than in the control group (P<0.05). The FACT-B scores of the two groups increased significantly after treatment (both P<0.05), but it was significantly higher in the observation group than in the control group (P<0.05). After treatment, the serum VEGF-C level increased significantly in the observation group (P<0.05), whereas the control group did not show significant change (P>0.05). The post-treatment serum VEGF-C level was significantly higher in the observation group than in the control group (P<0.05). Conclusion: The efficacy of mild moxibustion combined with functional exercise for upper-limb lymphedema after breast cancer surgery is certain, which can reduce the difference in circumference between the two upper limbs, increase the lymphatic flow of the affected upper limb, improve the limb function and the quality of life, and regulate the serum VEGF-C level.

It is well believed that learning and memory is one of the functions of sleep.Not only does the sleep after learning aid memory consolidation, but enough sleep before learning is necessary for memory formation.Due to the net increase in synaptic strength, waking plasticity has a cost in terms of energy requirements, space requirements, and progressively saturates the capacity to learning.The review will focus on the role of sleep which is to downscale synaptic strength to a baseline level that is beneficial for learning and memory.

Executive impairment is one of the common sequelae of stroke, which seriously affects the quality of life of patients. Repeti-tive transcranial magnetic stimulation (rTMS), as a new type of electrophysiological technique, has been used in the clinical treatment of Post-Stroke Executive Impairment (PSEI). This paper summarized the survey of PSEI, the basic principle and mechanism of rTMS, clinical application of rTMS for PSEI and its safety. Clinical studies showed that high frequency stimulation, low frequency stimulation, and combi-nation with other therapeutic methods were effective in PSEI. However, there was no unified theory about the mechanism and the best treat-ment plan of rTMS for PSEI.
