RESUMO
Objective To investigate the effect of berberine on gut microbiota and T helper cell 17 (Th17), regulatory T cell (Treg) cell in sleep deprived rats.Methods SD rats were randomized into control group, model group, low-dose and high-dose group (BBR1 and BBR2, 100 mg/kg and 200 mg/kg, administrated orally).Sleep deprived rat model was established by the small-platforms-over-water method.The number of bacteria in rectum content of rat was detected.The ratio of Th17/Treg was evaluated by flow cytometry.The expression of interleukin 17 (IL-17), RAR-related orphan receptor (ROR) C, and Forkhead Box Protein P3 (Foxp3) mRNA was evaluated.Results The counting of Clostridium perfringens was elevated (P<0.05), the amount of other microbiota decreased (P<0.05), Th17/Treg ratio(P<0.05), IL-17 and RORC expression enhanced (P<0.05), Foxp3 expression decreased (P<0.05) in the gut of model rats.In contrast, treatment with berberine inhibited the proliferation of Clostridium perfringens(P<0.05), and promoted the growth of other microbiota (P<0.05), and dampened Th17/Treg ratio (P<0.05), regressed IL-17 and RORC expression, augmented Foxp3 expression.Conclusions Various doses of berberine can counteract gut microbiota imbalance and Th17/Treg imbalance induced by sleep deprivation.
RESUMO
Objective To investigate the pefinatal infant brain damage in the blcod of neuron specific enolase and long-term changes in the development of nervous system disordem related to the neonatal brain injury prognosis timely predictions for the early intervention and provide a theoretical basis.Methods 40 cases of periatal brain injury in newborns were selected for the study.20 patients over the same period of normal newborns assigned to the control groups.both groups in the 72 hours after birth within the collected blood samples submitted preservation of the neuronspecific enolase enzyme,and rely follow-up of the two groups,so as to cover Gesell development scale statistical analysis of neuron specific enolase and perinatal brain damage in children with long-term development of nervous system disorder relevant.Results Brain injury group blood neurompeeifie enolase concentrations were higher:15-month-old brain-injury group scale evaluation of sale to group health suspicious after three clays of Mood neuronspecific enolase concentrations significantly higher to the development of the normal group.Conclusion Neuronspecific enolase may change as early diagnosis of perinatal brain injury,as well aft the main indicators of the long-term prognosis.
