The anti-inflammatory effects of exercise on autoimmune diseases: A 20-year systematic review.

BACKGROUND: The anti-inflammatory effect of exercise may be an underlying factor in improving several autoimmune diseases. The aim of this systematic review was to examine the evidence on the role of exercise training in mitigating inflammation in adolescents and adults with autoimmune disease. METHODS: PubMed, Web of Science, and Embase databases were systematically reviewed for related studies published between January 1, 2003, and August 31, 2023. All randomized and non-randomized controlled trials of exercise interventions with autoimmune disease study participants that evaluated inflammation-related biomarkers were included. The quality of evidence was assessed using the Tool for the assEssment of Study qualiTy and reporting in EXercise scale and Cochrane bias risk tool. RESULTS: A total of 14,565 records were identified. After screening the titles, abstracts, and full texts, 87 were eligible for the systematic review. These studies were conducted in 25 different countries and included a total of 2779 participants (patients with autoimmune disease, in exercise or control groups). Overall, the evidence suggests that inflammation-related markers such as C-reactive protein, interleukin 6, and tumor necrosis factor α were reduced by regular exercise interventions. Regular exercise interventions combined with multiple exercise modes were associated with greater benefits. CONCLUSION: Regular exercise training by patients with autoimmune disease exerts an anti-inflammatory influence. This systematic review provides support for the promotion and development of clinical exercise intervention programs for patients with autoimmune disease. Most patients with autoimmune disease can safely adopt moderate exercise training protocols, but changes in inflammation biomarkers will be modest at best. Acute exercise interventions are ineffective or even modestly but transiently pro-inflammatory.

The effect of PBL combined with comparative nursing rounds on the teaching of nursing for traumatology.

OBJECTIVE: To investigate the effect of problem-based learning (PBL) combined with comparative nursing rounds on the teaching of nursing for traumatology. METHODS: This prospective study was performed in 186 nursing student interns. According to a random number table, these interns were assigned to the control group (n=93) and the experimental group (n=93). In the control group, the interns received traditional teaching methods. Meanwhile, interns in the experimental group received PBL combined with comparative nursing rounds teaching. The level of teaching approval, excellent and good rate of theoretical knowledge, operational ability, medical record writing, and critical thinking disposition inventory-Chinese version scores were compared between the two groups. RESULTS: Teaching approval in learning initiative, problem solving ability, critical thinking, clinical work ability, independent information acquisition ability, and teamwork spirit in the experimental group were improved compared with the control group (all P<0.05). The excellent and good rate of theoretical knowledge, operational ability, and medical record writing in the experimental group were all higher than those in the control group (all P<0.05). Compared with the control group, critical thinking disposition inventory-Chinese version scores in all aspects in the experimental group after training were improved (all P<0.05). CONCLUSION: The application of PBL combined comparative nursing rounds in the teaching of nursing for traumatology is beneficial for a significant improvement in the grasp of theoretical knowledge, operational ability, critical thinking ability, and teaching approval.

LncRNA MEG3 overexpression inhibits the development of diabetic retinopathy by regulating TGF-ß1 and VEGF.

In view of the high incidence of diabetic retinopathy and the functionality of long non-coding RNA (lncRNA) maternally expressed gene 3 (MEG3) in different disease models, the present study aimed to investigate the role of MEG3 in diabetic retinopathy. In the study, patients with diabetic retinopathy, diabetic patients without retinopathy as well as healthy people were included. Fasting blood was extracted from each participant. Serum MEG3 levels were detected by everse transcription-quantitative polymerase chain reaction (RT-qPCR) and serum vascular endothelial growth factor (VEGF) and transforming growth factor-ß1 (TGF-ß1) levels were detected by ELISA. Also, the effects of high glucose treatment on the expression of MEG3 and VEGF and the effects of MEG3 overexpression on expression of VEGF and TGF-ß1 in high glucose-treated ARPE-19 cells were detected by RT-qPCR and western blot analysis to determine the mRNA and protein levels, respectively. It was indicated that serum levels of MEG3 were significantly lower, while the serum levels of VEGF and TGF-ß1 were significantly higher in patients with diabetic retinopathy and diabetic patients without retinopathy compared with the healthy controls. Furthermore, slight differences were found between patients with diabetic retinopathy and diabetic patients without retinopathy; however, these differences were not significant. The findings indicated that high glucose upregulated the expression of VEGF mRNA and downregulated the expression of MEG3, MEG3 overexpression reduced the increased expression levels of VEGF and TGF-ß1 induced by high glucose treatment. Therefore, it was concluded that lncRNA MEG3 overexpression may inhibit the development of diabetic retinopathy by inhibiting TGF-ß1 and VEGF expression.
