1H NMR-based metabolomic study of striatal injury in rats with copper-loaded Wilson's disease by Chinese and Western medicine intervention.

OBJECTIVE: To investigate the metabolic mechanisms of Chinese and Western medicines on the metabolic network of striatal injury in a copper-loaded rat model of Wilson disease (WD) from a metabolomic perspective. METHODS: We divided 60 rats into 4 groups of 15 rats each according to a random number table, namely the control group, the model group, the Bushen Huoxue Huazhuo Recipe group, and the penicillamine group, and subsequently replicated the WD copper-loaded rat model according to the literature method for a total of 12 weeks. From the 7th week onwards, each intervention group was given an equivalent dose of the corresponding drug, and the control and model groups were given an equal volume of saline gavage until the end of the model replication. We used 1H NMR metabolomics techniques combined with multivariate statistical methods to describe the changes in the striatal metabolic profile of nerve injury in Wilson's disease and to analyze the effect of different treatments on their biomarker interventions. RESULTS: Nerve cell damage was evident in the WD copper-loaded rat model and could be reduced to varying degrees by different methods of intervention in the striatal nerve cells. The content of glycine, serine metabolism, and valine metabolism decreased in WD copper-loaded rat model; aspartate content increased after penicillamine intervention; glycolytic metabolism, valine metabolism, taurine metabolism, and tyrosine metabolism increased in the group of Bushen Huoxue Huazhuo Recipe. CONCLUSION: Different intervention methods of Chinese and Western medicine affect aspartate, glycolysis, taurine, tyrosine, valine, and carbon metabolism in striatal tissues of WD copper-loaded rats, and can regulate the metabolism of small molecules, which in turn have certain repairing effects on nerve damage in WD copper-loaded rats.

[Correlation between cervical curvature and cervical disc bulging in young patients with neck pain].

OBJECTIVE: To explore the correlation between the curvature of the cervical spine and the degree of cervical disc bulging in young patients with cervical pain. METHODS: The clinical data of 539 young patients with neck pain from January 2015 to December 2018 were retrospectively analyzed. There were 251 males and 288 females, aged 18 to 40 (32.2±6.3) years old. The cervical curvature and cervical disc bulging were measured by cervical X-ray and MRI. According to cervical curvature, the patients were divided into 175 cases of cervical lordosis group (cervical curvature > 7 mm), 163 cases of cervical erection group (0
