Objective To discuss the diagnostic value of detecting plasma vitamin B12 and Homocysteine (Hcy) in subacute combined degeneration of the spinal cord (SCD).Methods Parents of SCD (n=29) and subjects (n=74) without spinal cord diseases were enrolled from the clinic of Shaanxi Provincial People's Hospital from April 2014 to July 2016.The plasma vitamin B12 and Hcy concentrations were detected using Chemiluminescence Immunoassay (CLIA) and enzyme-linked immuno sorbent assay (ELISA) respectively,and compared using chi-square between the SCD and control groups.Sensitivity rate,specific rate,and diagnose accordance rate were evaluated.Results The plasma homocysteine and vitamin B12 concentrations in SCD and control groups were 49.41 μmol/L vs 12.36 μmol/L,44.35 pg/ml vs 166.75 pg/ml,with significant differences (U=343.50,800.00,P＜0.05).Negative correlation existed between the concentrations of vitamin B12 and Hey (r=-0.248,P=0.012).The sensitivity rates of vitamin B12 and Hcy detections were 55.2％ vs 89.7％,which had significant differences (x2 =8.631,P=0.003),and the diagnose accordance rate (69.9％ vs 64.1％) of the former was higher (x2 =4.175,P=0.041).Conclusion The plasma Hcy and vitamin B12 concentration detections had definite diagnostic value in SCD,and Hcy had higher sensitive rate,which can improve the diagnostic rate of SCD in the early stage.

Objective To determine the contents of elements Fe, Mn, Ni, Cu, Zn, Ca, Mg and Cr in Gentiana macrophlla and Gentiana officinalis. Methods The contents of elements were determined by flame atomic absorption spectrometry. Results The recovery rates obtained by standard addition method were between 88.1%～114.5%, and the RSDs were lower than 3.18%. Gentiana macrophlla is rich in the trace elements such as Fe, Ni, Cu, Ca, Mg, and Gentiana officinalis is rich in the trace elements such as Mn, Zn, Cr. Conclusion There are some difference between wild and planted Gentiana officinalis in element content, that may be related to their growing environment.

BACKGROUND: There have been reports at home and abroad about effects of estrogen upon the dopamine amount in substantia nigra in the midbrains while the neuroprotective effects of estrogen are still being studied.OBJECTIVE: To observe the effects of estrogen on dopaminergic neurons and explore the feasibility of preventing and treating Parkinson disease with estrogen.DESIGN: A randomized controlled study based on the experimental animals.SETTING: General neurosurgery institute in a hospital of a military medical university of Chinese PLA.MATERIALS: The trial was conducted in the General Neurosurgery Institute of Xijing Hospital,the Fourth Military Medical University of Chinese PLA from October 2003 to February 2004 with 50 healthy,first-grade Wistar rats as subjects. INTERVENTIONS: The rats were randomly assigned into 5 groups with 10in each group. Group 1 was normal control,group 2 sham-operation group,and groups 3,4,5 were ovariectomy groups. In group 3,10 μg of estradiol was administered twice a day ineach rat after ovariectomy. Each rat in group 4 was administered with estrogen antagonist,5 μg tamoxifen twice a day as well as estrogen. In group 5,only ovariectomy was performed. After stereotaxic injection of 6-hydroxydopamin into substantia nigra in the midbrains,the TH positive neurons were labeled and counted with immunohistochemic method and the rat's behavior was observed.MIAN OUTCOME MEASURES:①the circles of rat's rotation provoked by apomorphine.②the TH positive neuron count in the middrains of rat's substantia nigra 30 days after ovariectomy.RESULTS: Baseline characteristics among the groups were no difference ( P ＞ 0.05). The result of group 3 was different from that of group 5 ( P＜ 0.05 ). The result of group 4 was also different from that of group 3 and group 5 (P ＜ 0.05) . The TH positive neuron count in the midbrains ingroup 3 also differed from that in other groups( P ＜ 0.05).CONCLUSION: Estrogen acts as a neuroprotectant of the nigral dopaminergic neurons in the midbrains not only through estrogen receptor-dependent pathways but probably also through others.
