ABSTRACT
Objective:To investigate the effects of abdominal Tuina(Chinese therapeutic massage)on behavioral function,5-hydroxytryptamine 1A receptor(5-HT1AR),and synapsin-1(Syn1)in neonatal rats with hypoxic-ischemic brain injuries(HIBI). Methods:Forty healthy neonatal rats,born of 5 specific pathogen-free healthy pregnant rats,were randomly divided into a group for modeling(n=28)and a sham operation group(n=12)on the 7th day of birth.In the group for modeling,24 neonatal rats with HIBI successfully established by the Rice method were randomly divided into a model group(n=12)and an abdominal Tuina group(n=12).The abdominal Tuina group was given abdominal Tuina for 28 d from 24 h after modeling,and the other groups were put under the same conditions but without any treatments.Rats in each group were subjected to suspension tests on the 7th,14th,21st,and 28th days of intervention.After the intervention,the rat hippocampal tissue was collected and stained with hematoxylin-eosin to observe the pathological changes in the rat hippocampal CA1 region.The 5-HT1AR expression in rat hippocampal CA1 region was detected by immune-histochemistry.The Syn1 expression in rat hippocampus was measured by Western blotting method. Results:The cells were disordered,and edema and necrosis appeared in the hippocampal CA1 region of the model group.Cell arrangement was clear,and edema was improved obviously in the hippocampal CA1 region of the abdominal Tuina group.Compared with the sham operation group,the suspension test scores,the number of 5-HT1AR positive cells,and Syn1 protein expression in the hippocampus decreased significantly in the model group after 21 d and 28 d of interventions(P<0.05).Compared with the model group,the suspension test scores,the number of 5-HT1AR positive cells,and Syn1 protein expression increased significantly in the abdominal Tuina group after 21 d and 28 d of interventions(P<0.05). Conclusion:Abdominal Tuina improves the behavioral function of upper limbs and up-regulates the expression levels of 5-HT1AR and Syn1 in the hippocampus of neonatal HIBI rats.
ABSTRACT
Objective:To investigate the effects of moxibustion on the serum metabolism in healthy human body based on the 1H nuclear magnetic resonance (1H NMR) metabolomics technology, and to find the differences in metabolites, as well as to elucidate the effects of moxibustion on healthy human body from the viewpoint of global metabolism. Methods:Sixty subjects of healthy young men from the enrolled students were randomly divided into a moxibustion group and a control group using random number table, with 30 cases in each group. Subjects in the moxibustion group accepted mild moxibustion on the right Zusanli (ST 36), once a day, 15 min for each time, and continuous treatment for 10 d; those in the control group did not receive any intervention. There were 28 cases in the moxibustion group and 23 cases in the control group after interventions. On the 1st day, 5th day and 10th day of the intervention, serum samples were collected from subjects of the two groups, and metabolic spectra were obtained by the1H NMR technology. Results: Before and after the intervention, serum1H NMR of the moxibustion group was significantly different, while the difference was insignificant in the control group. Metabolite changes in the moxibustion group were mainly in low density lipoprotein (LDL)/very low density lipoprotein (VLDL), valine, isoleucine, leucine, lactic acid, glutamine, citric acid, polyunsaturated fatty acids, creatine, glycine, glycerol, glucose, tyrosine, histidine, formic acid, alanine, lysine, acetic acid, and glutamic acid. Conclusion:Moxibustion can cause changes of serum metabolic patterns in healthy human by influencing the concentrations of branched-chain amino acids, polyunsaturated fatty acids, and other metabolites to strengthen body's metabolisms of amino acids and fatty acid.
