Objective To study the incidence and clinical significance of abnormal neuroendocrine hormone in patients with the syndrome of brain injury.Methods 67 cases with the syndrome of brain injury were included in the study group,and 95 cases without the post traumatic syndrome after brain injury were included in the control group.The level of FT3,FT4,TSH,growth hormone(GH),andrenocortico hormone(ACTH),cortisol (Cor),prolactin(PRL),testosterone (T),estradiol (E2),follicular stimulating hormone (FSH),luteotropic hormone (LH),and progesterone (P) in peripheral blood were measured by radioimmunoassay.The incidence of the abnormal neuroendocrine hormone after brain injury was statistically analyzed.Patients with abnormal hormone were given hormone replacement therapy and the curative effects were observed.Results The incidence of neuroendocrine hormone abnormalities was 38.8％ in patients with the syndrome of brain injury,while it was 10.5％ in the control group.There was significant difference between the 2 groups(P＜0.05).The symptom remission rate was 88.5％ after hormone treatment.Conclusions There was a high incidence of abnormal neuroendocrine hormone secretion in patients with the syndrome of brain injury.The hormone level may be used as an important index to guide clinical therapy.

Objective To explore the effects of Caspase-3 and Glypicante1 (Gpc1) altered expressions on the proliferation of glioma cells and its mechanism.Methods Fifty-two glioma specimens and 13 normal cerebral tissues were collected in our hospital from October 2011 to October 2014;the protein expressions of Caspase-3 and Gpc1 in these tissues were detected with immunohistochemistry.The peDNA3.1/Gpc 1 high expression plasmids were constructed;human glioma A172 cell lines were routinely cultured in vitro;the signal path changes of Hedgehog (H-h) in the A172 cells after being transfected with 0.5,1,2 and 4 μg peDNA3.1/Gpc1 high expression plasmids were detected by Luciferase luciferase reporter gene kit.Gpc 1-1694 interference plasmids were transfected into the A172 cells to silence the Gpc1 expression and these A172 cells were given 8 iμg/mL Blasticidin (experimental group) for 24 h;normal A172 cells were given the same volume of solvent (control group);altered expressions of G-pc 1 were detected by immumohistochemical staining and proliferation activity of the cells were observed by MTT assay 24,48,72 and 96 h after transfection.Results The expressions of Caspase-3 and Gpc1 in the glioma specimens were significantly higher than those in the normal brain tissues (P＜0.05);in the glioma specimens,positive correlation between Caspase-3 and Gpc1 was noted (r=0.486,P=0.000).As compared with the control group,increased fluorescence intensity was observed in the 0.5,1,2 and 4 μg peDNA3.1/Gpc1 high expression plasmids groups (P＜0.05);immumohistochemical staining showed that CyclinD1 expression in the Hh pathway of in the peDNA 3.1/Gpc1 high expression plasmids groups was significantly lower than that in the control group;MTT assay showed that the proliferation activity of the A172 cells in the peDNA3.1/Gpc1 high expression plasmids groups at 24,48,72 and 96 h after transfection was significantly lower than that in the control group (P＜0.05).Conclusion Caspase-3 and Gpc1 play important roles in regulating the proliferation of glioma cells,which might be related to Hedgehog signaling pathway.
