Acta Anatomica Sinica 1955;0(03):-
The fibre projections of the caudate nucleus to the cerebral cortex and the nonspecific thalamic nucleus in the rabbit were studied by tracing the degenerated axons and terminal fibres from electrolytic lesions in the head portion of the nucleus on sections prepared with Nauta and Glees methods.The results were as follows:The efferent fibres from the head portion of the caudate nucleus were projected to frontal (especially the praecentral areas) and limbic cortex, and terminated in all the layers of the cerebral cortex.The efferent fibres from the head portion of the caudate nucleus were projectet to the centromedian nucleus and parafascicular nucleus of the nonspecific thalamic nuclei.The above observations suggest that the projection of the efferent fibres from the caudate nucleus to the cerebral cortex and nonspecific thalamic nuclei may be a parf of the nonspecific conducting pathway; and the caudate nucleus is not only a part do the extrapyramidal system but a structure of the nonspecific conducting system which may serve as the morphological basis for the role played by the caudate nucleus in the acupunctural analgesia.
3.The receptor for advanced glycation end products and lung development and lung injury
International Journal of Pediatrics 2013;40(5):454-457
The receptor for advanced glycation end product (RAGE) is a member of the immunoglobulin superfamily of cell surface molecules.As a pattern recognition receptor,it can bind with a variety of ligands.The adult lung is unique in which it expresses high amounts of RAGE under normal conditions while other tissues express low amounts normally and up-regulate RAGE during pathologic processes.The lung exhibits high basal level expression of RAGE localised mainly in alveolar type I cells,suggesting a potentially important role for the receptor in epithelial cell proliferation and differentiation and maintaining lung homeostasis.Indeed,disruption of RAGE levels has been implicated in the pathogenesis of a variety of pulmonary disorders such as acute and chronic lung injury.Furthermore,its soluble form sRAGE,as a decoy receptor,has been shown as an important marker of alveolar epithelial type I cell injury.Studies have suggested that RAGE plays an important role in the biology of the lung and may become a therapeutic target for lung injury.
4.Study on the protective effect of MgSO4 on the radiation-induced neural stem cell injury
Chinese Journal of Radiological Medicine and Protection 2010;30(6):639-642
Objective To explore the neuroprotective effect of magnesium sulfate on radiation induced neural stem cell injury. Methods Brain tissue was obtained from new-born sprague-dawley rats within 24 hours, and the cerebral hemisphere was dissociated to culture the neural stem cells. After being identified by immunofluorescence method, the neural stem cells were randomly divided into 3 groups as blank control group, experimental control group and experimental group. The neural stem cells of experimental control group and experimental group were irradiated with 2 or 4 Gy of gamma rays. The proliferation and the cell cycle of neural stem cells were detected at different time-points ranging from 24 h,48 h, 72 h after irradiation with CCK-8 and FCM. Results Compared with the blank control group, the proliferation rate of experimental control group was significantly reduced ( t = 5. 33-8.44, P < 0. 05 ), and the G1 phase arrest of experimental control group was significantly enhanced ( t = 30. 60-71.22, P < 0. 05 ).Compared with the experimental control group, the proliferation of experimental group significantly increased excluding that of 24 h ( t = 2.45-4. 71, P < 0.05 ), the apoptosis rate of experimental group significantly decreasd (t = 6.73-41.12, P < 0.05 ), which was closer to the blank control group.Conclusion Magnesium sulfate can alleviate the injury of proliferation and decrease the cell apoptosis in the early stage after irradiation.
5.Effects of thermotherapy on Th1/Th2 cells and plasma VEGF in non-small cell lung cancer patients treated with chemotherapy
Journal of Chinese Physician 2016;18(5):713-716
Objective To investigate the effect of hyperthermia combined with chemotherapy on the changes of immunity balance of Th1/Th2 and cytokines such as interleukin-2 (IL-2),interferon-γ (IFN-γ),IL-4,IL-10,and vascular endothelial growth factor (VEGF) in non-small cell lung cancer (NSCLC) patients.Methods Fifty patients with advanced NSCLC were randomly divided into thermochemotherapy group (n =25,received whole body hyperthermia combined TP chemotherapy),and chemotherapy group (n =25,received TP chemotherapy alone).The immunity balance of Th1/Th2,IL-2,IFN-γ,IL-4,IL-10,and VEGF levels before therapy and 1 week after therapy were observed.At the same time,the above observation indices were also detected as normal control in 20 healthy volunteers.Results Compared to the chemotherapy group,the proportion of Th1 cells from thermochemotherapy group was significantly increased after therapy (P =0.002) and that of Th2 cells was dropped markedly (P =0.006).There was no difference in the levels of IL-2,IFN~,IL4,IL-10,and VEGF between thermochemotherapy and chemotherapy groups before therapy (P > 0.05).However,the expressions of ILA,IL-10,and VEGF in the NSCLC group were significantly higher than normal group (P < 0.01).The IL-2 and IFN-γ levels were significantly decreased in NSCLC group (P <0.01).After therapy 1 week,the concentration of IL-2 and IFN-γfrom thermochemotherapy and chemotherapy groups were higher than before,with statistical significance (P <0.01).In addition,IL-4 and IL-10 levels of two groups were significantly decreased in comparison with before therapy (P < 0.01),and it showed a striking difference in cytokines (IL-2,IFN-γ,IL-4,and IL-10) between two groups (P < 0.05).However,the concentration of VEGF in chemotherapy group patients before and after chemotherapy had no significant difference (P > 0.05).The concentration of VEGF from thermochemotherapy group patients after therapy were lower than chemotherapy group patients,the difference had statistical significance (P < 0.01).Conclusions Thermochemotherapy can significantly prompt the Th2 to Th1 shift in both cells and cytokines of advanced NSCLC compared to chemotherapy alone.Moreover,thermochemotherapy also reduces the expression of VEGF,which may prevent the formation of new blood vessels in tumor tissue.
6.Correlation Between Objective Multi-parametric Analysis and Perceptual Analysis for Dysphonia
Journal of Audiology and Speech Pathology 1998;0(03):-
Objective To develop a multi-parametric objective evaluation protocol and investigate its correlation with perceptual analysis of continuous speech for objectivity and quantitatively. Methods The voice samples were collected from 135 patients with dysphonia and 29 subjects with normal voice. The objective parameters, including fundamental frequency (F 0), intensity, jitter, signal-to-noise ratio, Lyapunov coefficient (LC),oral airflow (OAF), vocal range (Range) and maximum phonatory time (MPT) which were measured mainly on a sustained /a/ and estimated subglottic pressure (ESGP) which was determined on a series of /pa/,were recorded on an "EVA" workstation which was developed in French. According to the G (overall dysphonia) component of the GRBAS score on a 4-point scale ranging from 0 for normal to 3 for severe dysphonia, the perceptual analysis was done by a jury composed of 4 experienced listeners and the voice samples (continuous speech) were from the same patients with normal voices and normal intensity. Results Using the discriminate analysis, a seven parameters protocol (Range, LC, ESGP, MPT, OAF, signal-to-noise ratio and F 0) was developed. Result showed that this protocol allowed 84% concordance with jury classification.Conclusion The objective voice evaluation is multi-parametric and is able to reflet the result of perceptual analysis.

Conclusion The triple viable bacterium of bacillus can promote the recurrence of patients with infectious diarrhea by adjusting the distribution of intestinal microflora, and by its immune regulation function.
9.Application of linear and nonlinear characteristics of heart rate variability in assessment of autonomic nervous system activity.
Journal of Biomedical Engineering 2014;31(2):302-307
Calculation of linear parameters, such as time-domain and frequency-domain analysis of heart rate variability (HRV), is a conventional method for assessment of autonomic nervous system activity. Nonlinear phenomena are certainly involved in the genesis of HRV. In a seemingly random signal the Poincaré plot can easily demonstrate whether there is an underlying determinism in the signal. Linear and nonlinear analysis methods were applied in the computer words inputting experiments in this study for physiological measurement. This study therefore demonstrated that Poincaré plot was a simple but powerful graphical tool to describe the dynamics of a system.
