RESUMO

Patients with novel coronavirus infection still have many functional disorders during the recovery period. The timely intervention of rehabilitation treatment has important clinical significance in improving the patients’ functions and their ability of daily living. Based on the current evidence of evidence-based medicine and clinical practice, this paper summarizes the rehabilitation treatment and precautions of patients with simple novel coronavirus infection and different groups with previous dysfunction and novel coronavirus infection (such as neurological dysfunction, chronic pain, and bone and joint diseases) with a view to providing clinical reference for the rehabilitation treatment of patients with novel coronavirus infection during the recovery period.

RESUMO

Objective To investigate changes in the firing activities of nucleus accumbens (NAc)neurons and their response to 5-HT7 receptor stimulation in a rat model of Parkinson’s disease (PD).Methods The firing activities and response of NAc neurons to 5-HT7 receptor agonist in PD rats were recorded by in vivo electroneurophysiology and neuropharmacology and then were compared with those in the sham group.Results The mean firing rate of NAc neurons was (5.46 ±0.88)Hz in the sham rats and (3.77 ±0.48)Hz in the PD rats. The firing rate of NAc neurons increased significantly compared with that in the sham rats (P 0.05 ).Systemic administration of 5-HT7 receptor agonist AS1 9 increased the firing rate of NAc neurons in the sham and PD rats.This excitation was significant at a high dose of 1 60 μg/kg for NAc neurons in the sham rats (P <0.05).However,the excitation produced by AS1 9 was significant at a high dose of 80 μg/kg in PD rats (P <0.05).The cumulative dose-produced excitation in the PD rats was lower than that in the sham rats.The effects induced by AS1 9 were reversed by the 5-HT7 receptor antagonist SB269970 in both groups.Conclusion The reinforced firing activity of NAc neurons might be mediated by 5-HT7 receptor in the neurons of PD rats.

RESUMO

Objective To investigate the altered expression of muscarinic receptor 2 (M_2 receptor) in the pedunculopontine nucleus (PPN) of Parkinson's disease (PD) model rat by immunocytochemical technique and explore the role of M_2 receptor in etiopathogenesis and pathophysiological changes of PD. Methods Sixteen healthy SD rats were divided randomly into two groups. Rat monoclonal antibody against the M_2 receptor was used. Then we used positive cell counting and optical density as indicators to analyze the altered expression of M_2 receptor in PPN of PD model rats. Results The counting of M_2 receptor positive cells in the PPN was not obviously changed in normal rats and the unlesioned side of PD rats (P>0.05), whereas a significant decrease was observed when compared to that in normal rats and the lesioned side of PD rats, respectively (P<0.05). However, the positive intensity in the three groups did not differ significantly. Conclusion The results indicate that there was a degenerative death or receptor loss of M_2 receptor positive cells in the lesioned PPN of PD rats. The expression intensity of M_2 receptor positive cells without degenrative death or receptor loss was not affected. It was also found that the factor affecting the change of M_2 receptor positive cells in the PPN involved only one side.
