Objective: To investigate the effect of upper limb rehabilitation robot assisted training on the event-related potential P300, upper limb function and quality of life in stroke patients. Methods: A total of 90 stroke patients admitted to Yuyao People's Hospital from May 2017 to January 2018 were randomly divided into control group(45 cases) and observation group(45 cases) according to the digital table.The control group received conventional rehabilitation exercise, and the observation group was supplemented by Motorika ReoGo upper limb rehabilitation robot on the basis of the control group.The P300 latency, P300 amplitude, upper limb function and quality of life of the two groups were compared before and after treatment. Results: Before training, the latency of P300, amplitude of P300, upper limb function and quality of life score had no statistically significant differences between the two groups(all P>0.05). After training, the latency of P300, amplitude of P300 in the control group were (389.54±28.19)ms, (2.79±0.23)μV, respectively, which in the observation group were (356.25±24.54)ms, (3.06±0.19)μV, respectively.The latency of P300 in both two groups was significantly shorter than those before training(t=4.490, 12.342, all P<0.05), and the amplitude of P300 were significantly higher than those before training(t=-3.476, -10.061, all P<0.05), which of the observation group were significantly better than those of the control group(t=-5.975, 6.071, all P<0.05). After training, the Fugl-Meyer scale(FMA) and Barthel scale(MBI) scores of the control group were (35.62±9.72)points, (81.35±10.96)points, respectively, which of the observation group were (44.65±11.23)points, (89.63±11.59)points, respectively.The FMA and MBI scores in the two groups were significantly higher than those before training(t=-5.107, -8.595, -9.039, -11.417, all P<0.05), which of the observation group were significantly higher than those of the control group(t=4.078, 3.482, all P<0.05). Conclusion Motorika ReoGo assisted upper limb rehabilitation robot can significantly improve P300 latency, amplitude, upper limb function and quality of life in stroke patients.

Testicular radiation injury is a structural and functional abnormality of the testes caused directly or indirectly by radiation, which disrupts spermatogenesis and compromises male fertility. The development of effective preventive and therapeutic interventions is essential because of the high prevalence of this condition in clinical settings and its profound effect on patients′ reproductive health and overall well-being. The concept of "the struggle between vital qi and pathogen" is first seen in the Treatise on Cold Pathogenic Diseases. It denotes the dynamic struggle between vital and pathogenic qi. The occurrence, development, and sequelae of all diseases reflect this ongoing conflict. In this context, this study defines the "vital qi" of the testis as its capacity to generate and preserve the essence of reproduction and to resist damage. The pathogenic qi associated with testicular radiation injury is categorized into two types: ionizing poison and retaining evil. The pathogenesis of testicular radiation damage is delineated into three stages by integrating the characteristics of vital and pathogenic qi: the injury, adhesion, and recovery phases. Based on the theoretical framework advanced by this study, the therapeutic approach for testicular radiation injury should adhere to the fundamental principle of strengthening vital qi and eliminating pathogenic factors. Although the primary focus of treatment should be on strengthening vital qi, it should also be complemented by strategies to eliminate pathogenic influences. This paper aims to provide a novel perspective and strategic approach to the traditional Chinese medicine diagnosis, prevention, and treatment of testicular radiation injury. By elucidating the process of testicular radiation injury and its corresponding treatment principles, it seeks to offer valuable insights for clinical practice.
