3.The Forensic determination of Post-Traumatic Epilepsy in 21 Patients
Journal of Forensic Medicine 2001;17(1):25-27
To evaluate the forensic determination of post cerebral traumatic epilepsy. Methods In 21 patients, traumatic history and previous history were analysied combined with the demonstrations of electroencephalogram(EEG), X-ray, CT and MRI. Results Post-traumatic epilepsy,manily in late stage, usually occurred following serious cerebral trauma. The type of traumatic epilepsy was determined by the traumatic location and extent. Abnormal epileptic wave in scalp EEG and 24h dynamic EEG and medical image examinations were helpful for qualitative analysis. Conclusion The forensic determination of post traumatic epilepsy must be on the basis of traumatic and previous history combined with EEG, CT and MRI analysis.

Objective: [WT5”,6BZ]To investigate the anti tumor effects of melittin in vitro . Methods: Melittin was isolated and purified from bee venom by gel filtration. The cytotoxicity of melittin against established cell lines(SMMC 7721,BEL 7402 and Hep 3B cell) was determined using by MTT assays. Mitomycin, vincristine and cinobu facini were used as control. The time effect relationship of melittin against SMMC 7721 cell line was studied. Results: Melittin showed the anti tumor effect in a dose dependent matter for tumor cells in vitro ,but there was no time effect relationship. The anti tumor effect of melittin was better than the control. Conclusion: Melittin has marked and quick anti tumor activity in vitro against established cell lines. [

Objective To investigate the influence of long-term blood purification on atherosclerosis(AS) in maintenance hemodialysis(MHD) patients by measuring serum levels of homocysteine(Hcy) and carotid artery intima-medial thickness(IMT).Methods Seventy-two MHD patients visiting our hospital from June 2006 to December 2007,according to their blood purification mode,were assigned to three groups: hemodialysis(HD,n=25),hemodialysis+hemodiafiltration(HD+HDF,n=30),hemodialysis+continuous renal replacement therapy(HD+CRRT,n=17).Another 25 healthy subjects served as controls.Serum Hcy was detected before and after one-year treatment and meanwhile color Doppler ultrasonography was performed to check IMT of carotid artery and atheromatous plaques.Results The serum levels of Hcy,IL-6,MCP-1,hs-CRP in MHD patients were significantly higher than those in healthy controls(P
7.Observation of the efficacy of Danhong injection combined with irbesartan in treatment of early diabetic nephropathy
Chinese Journal of Primary Medicine and Pharmacy 2011;18(3):291-292
Objective To evaluate the effect of the Danhong injection combined with irbesartan in treatment ofearly diabetic nephropathy. Methods 64 patients with early diabetic nephropathy were randomly divided into two groups and the control group 32 cases,two groups were given control of blood sugar and ensure water and electrolyte balance,support therapy,in which 32 cases were also observed red Danhong injection,Ecuador irbesartan treatment,2weeks before evaluation. Results The total effective rate in treatment group was higher than the control group( x2 =6.38 ,P <0. 05) ,after 12 weeks of treatment,two groups of urinary protein decreased significantly compared with before treatment, including observation of urine protein was ( 0. 6± 0. 1 ) g/24h, the control group was ( 0. 7 ± 0. 3 ) g/24h,and decreased urine protein level of the observation group was better than the control group( t = 2. 74,P < 0. 05 ). And in the course of treatment, side effects and serious adverse events were not found. Conclusion Danhong injection combined irbesartar, could improve the clinical symptoms, reduce microalbuminuria in treatment of early diabetic nephropathy is worthy of wider application.
8.A MORPHOLOGICAL STUDY OF CONNECTIONS BETWEEN ENKEPHALIN IMMUNOREACTIVE TERMINALS AND ?-AMINOBUTYRIC ACID IMMUNOREACTIVE NEURONS IN THE ROSTRAL PORTION OF THE NUCLEUS TRACTUS SOLITARIOUS OF THE RAT
Acta Anatomica Sinica 1954;0(02):-
Objective To observe the connections between enkephalin immunoreactive(ENK-ir) terminals and ?-aminobutyric acid immunoreactive(GABA-ir) neurons in the rostral portion of the nucleus tractus solitarious(rNTS) of the rat. Methods Double-immunofluorescent labeling method and the pre-embedding immunohistochemical staining combined with immuno-gold particles labeling technique for electron microscopic detection were used in the present study. Results Under the laser scanning confocal microscope,dense ENK-ir fibers and terminals and some GABA-ir neurons were observed in the rNTS.Close contacts between ENK-ir terminals and GABA-ir cell bodies were also detected.By using the electron microscopic technique,ENK-ir reaction products were found to be mainly localized on the surface of round clear vesicles and dense-cored vesicles in the axon terminals.ENK-ir terminals formed symmetric,which was a dominant pattern,and asymmetric synaptic connections with GABA-ir and immunonegative cell bodies and dendrites.Conclusion The ENK-ir terminals might take part in the transmission and regulation of the taste information in the rNTS through inhibiting,exciting the GABAergic neurons or inhibiting directly the activity of neurons within the rNTS.

Chinese Journal of Biochemical Pharmaceutics 2014;37(7):40-42,45
Objective To explore the role of halofuginone in immune regulation,observe the effects of halofuginone on maturation of dendritic cells and immune tolerance during homograft heart transplantation of rats,in order to provide new ways and means to treat transplantation tolerance and to explore its possible mechanism.Methods Rat bone marrow derived dendritic cells were isolated and the effects of halofuginone in LPS-treated DCs were investigated by flow cytometry;heart transplantation model of rats were established and the effect of halofuginone stimulated dendritic cells in the immune tolerance by pathological analysis and mixed lymphocyte reaction were observed.Results Flow cytometry results show that the expression of cell surface CD80 CD86,OX62 antigens were not high in control group,their expression increased significantly when stimulated by LPS for 24h,and decreased when stimulated by both Changshan ketone and LPS for 24h,and even lower than their expression levels in blank group,which showed that Changshan ketone has the ability to inhibit the maturation of dendritic cells induced by LPS.In rat heart transplantation model,dendritic cells stimulated with Changshan were injected into recipient rats in vivo,and receptor of rat transplantation rejection decreased significantly,which showed that dendritic cells stimulated with Changshan ketone may be used as a new method for cell therapy in treatment of transplant rejection.Conclusion This study systematically observes that halofuginone can inhibit the maturation of rat bone marrow-derived dendritic cells and lymphocyte proliferation for the first time in vivo and in vitro.
10.Research on effects of radiation on hippocampus neuron and the related molecular mechanism
China Medical Equipment 2013;(11):1-3
Objective:To explore the effects of radiation on hippocampus neuron and the related damage mechanism in order to provide the theory base for treatment strategy of radiation brain injury. Methods:We looked up the scientific literature including following methods. Pregnant mice were irradiated with tritiated water, and then the contents of SOM in pars intermedia and AVP in hypothalamus of newborn mice were detected by radioimmunoassay. Pregnant rats were irradiated with tritiated water or X-ray, and the neuronal cells derived from the newborn rats were cultured. The morphology of cultured neuronal cells was compared with those of normal neuronal cells. The number of apoptotic cells in cortical fifth layer was measured by HE staining. Results:After radiation with tritiated water, the level of SOM in pars intermedia of newborn mouse and AVP content in hypothalamus content of male newborn mouse significantly increased and decreased, respectively. Radiation with tritiated water could result in the morphology change of neuronal cells and increase the percent of apoptosis cells in cortical fifth layer. Moreover, the percent of apoptosis cells in tritiated water group was higher than that in the X ray group. Conclusion: Radiation could impact on brain neuropeptide contents, and neurobehavioral, learning and memonic ability, result in the morphology change of hippocampal neurons, and induce the midbrain cells apoptosis.
