ObjectiveTo systematically review the effect of resilience intervention on rehabilitation of traumatic brain injury. MethodsThe literatures related to resilience intervention on rehabilitation outcome of patient with traumatic brain injury were retrieved from PubMed, ScienceDirect, CNKI, Wanfang data and VIP databases through subject headings retrieval. The retrieval time was from establishment to December 31th, 2021. After filtering, the research, country, research object, research design, intervention frequency, intervention effect, rehabilitation impact and influencing factors were extracted from the literature, and the methodological quality was evaluated using the PEDro scale. ResultsA total of six valid literatures were obtained, which mainly focused on the research of resilience intervention on physical function, post-traumatic stress disorder, psychological function and social adaptation of patients with traumatic brain injury. ConclusionResilience intervention could reduce the patients' physical symptoms and post-traumatic stress disorder, and promoted the recovery of psychological functions, allowing them to maintain an optimistic attitude, and adopt flexible and effective coping style to adapt to the society.

ObjectiveTo observe the effect of twelve-week aerobic exercise on inhibitory control abilities and the change of brain activation in overweight children. MethodsFrom October to December, 2021, 20 overweight children from a primary school in Changping District were selected for a twelve-week aerobic exercise intervention. Their inhibitory control abilities were measured by Flanker task before and after intervention, while their brain activation levels during the task were detected by functional near infrared spectroscopy (fNIRS). ResultsThe interactions between task type and time of accuracy and reaction time in inconsistent tasks Flanker task were significant (F > 9.277, P < 0.05), with higher accuracy and lower reaction time of after intervention (P < 0.05). After intervention, ch1, ch2, ch3, ch6, and ch8 channels were activated by inconsistent tasks (P < 0.05). ConclusionA twelve-week aerobic exercise intervention could improve the inhibitory control ability, and increase the prefrontal cortex activation during inconsistent tasks in overweight children.

Tumor volume increases continuously in the advanced stage, and aside from the self-renewal of tumor cells, whether the oncogenic transformation of surrounding normal cells is involved in this process is currently unclear. Here, we show that oral squamous cell carcinoma (OSCC)-derived small extracellular vesicles (sEVs) promote the proliferation, migration, invasion, and epithelial-mesenchymal transition (EMT) of normal epithelial cells but delay their apoptosis. In addition, nuclear-cytoplasmic invaginations and multiple nucleoli are observed in sEV-treated normal cells, both of which are typical characteristics of premalignant lesions of OSCC. Mechanistically, miR-let-7c in OSCC-derived sEVs is transferred to normal epithelial cells, leading to the transcriptional inhibition of p53 and inactivation of the p53/PTEN pathway. In summary, we demonstrate that OSCC-derived sEVs promote the precancerous transformation of normal epithelial cells, in which the miR-let-7c/p53/PTEN pathway plays an important role. Our findings reveal that cancer cells can corrupt normal epithelial cells through sEVs, which provides new insight into the progression of OSCC.
