To investigate the relationship between development of traumatic brain edema and changes in posterior hypothalamus excitability, different nuclei of the hypothalamus were excited with electrical stimulation. According to the stimulation method, forty rabbits were randomly divided into the following groups. Group A animals( n =8) were not stimulated and used as the sham control. Group B animals( n =8) underwent stimulation of the posterior nucleus of hypothalamus (PH), Group C ( n =8) stimulation of the dorsal medial nucleus of the hypothalamus (DMH), and Group D ( n =8) stimulation of the ventral medial nucleus of the hypothalamus (VMH). In group E animals( n =8), ? receptor antagonist Regitine was injected intravenously before stimulating PH. During the course of stimulation, intracranial pressure (ICP) was monitored continuously. 3h later, the animals were sacrificed and their cerebral tissue was examined for content of water, K + and Na + . Changes in blood brain barrier (BBB) were traced by a colloidal gold technique. The results showed that stimulation of the three nuclei caused an acute elevation of ICP,which was significantly higher than that before stimulations ( P

OBJECTIVE: To investigate the effect of compound pollen typhae extract on nephritis hematuria and renal function in rats, the pharmacodynamics evaluation laid a foundation for the development of hospital preparations compound pollen typhae granule. METHODS: The rat model of renal hematuria was induced by immunogen bovine serum albumin (BSA) gavages, carbon tetrachloride (CCl4) subcutaneous injection, and lipopolysaccharide (LPS) tail vein injection. Intragastric administration of high, medium and low-dose compound pollen typhae extract was performed for 6 weeks. Testing concentration of serum creatinine (SCr), urea nitrogen (BUN) and total protein (TP) in rat blood, and 24 h urine protein, urine creatinine quantitative, urine deformed erythrocyte number were detected in the fourth week and sixth week respectively. RESULTS: Compound pollen typhae extract reduced the urine deformed erythrocyte number, 24 h urinary proteins quantitative, cut down SCr and BUN, and increased TP and CCr, there are significant differences(P < 0.01 or P < 0.05). CONCLUSION: Compound pollen typhae extract is effective in the treatment of glomerulonephritis hematuria in rat model through improving renal function, with high dose group of best effect.

Objective To explore the rule of early Jun’ expression in craniocerebral gunshot injury and its significance. Methods After a direct shot of the dog′s head with a small calibre rifle, the expression of Jun ′ protein was assayed by immunohistochemistry method at different periods and in different regions, and the water contents and the ultrastructural changes in brain tissue were also observed. Results Nearly no Jun expression was found in cerebral tissues of the control group. However, the Jun expression was first observed begun at 30min postinjury both at the regions of contusion and concussion ( P

Objective To investigate the application of Neurological Classification of Spinal Cord Injury (ASIA) in China.MethodsThe articles were retrieved in CNKI website (www.cnki.net),full-text Chinese journal database using the following parameters:searching words:"spinal cord injury" and "ASIA",publication time:1979-2006.Results164 articles were harvested,and 140 relevant papers of them were selected for analysis.ConclusionASIA Classification is widely used in China(Mainland).Constructive suggestions for the modification of this Classification were accumulated,while delayed use and misuse of it were found in some studies.

Glioma is the most common form of brain cancer. Despite recent advances in the treatment of solid tumors, there are few effective treatments for malignant gliomas due to its infiltrative nature. It has important significance to improve the treatment of glioma through in-depth understanding the intracerebral metabolic characteristics and pharmacokinetics of chemotherapeutics. Brain microdialysis (B-MD), an effective method to monitor central nervous system anticancer drug disposition, conditions of drugs through the blood-brain barrier, basic pathophysiologic metabolism, bioactive compounds and the changes of neurotransmitter in brain, provides the unique opportunity to allow the simultaneous determination of unbound concentrations of drugs in several tissues, and directly measure gliomas biochemistry continuously. B-MD has been able to monitor the change of brain drugs, metabolites and neurotransmitters, dynamic analysis of the drug concentration and pharmacological effect after administration, pharmacodynamic interaction between drugs, receptor mechanism of drug transport, as well as feedback information of internal environment. B-MD is expected to provide reference for clinical individual chemotherapy of glioma, but also provide powerful tools for the evaluation of new anticancer drugs in vivo. In this review, a comprehensive overview of B-MD for studies on glioma is elucidated with special emphasis on its application to neurochemistry and pharmacokinetic studies.

Therapeutic strategies targeting tumor angiogenesis have been approved for cancer therapy. Vasculature normalization induced by anti-angiogenic drugs can restore abnormal tumor vessels, and improve the tumor microenvironment characterized by hypoxia, extracellular acidosis, and high interstitial lfuid pressure, improve the cancer treatment results by chemoradiotherapy and immunotherapy.

Earthquake can result in a large number of patients with spinal cord injury(SCI).The unique characteristic of spine trauma with SCI leads to challenges in the search-and-rescue phase and early trauma care for these patients.Rescue workers should be aware of the importance of spinal immobilization in people who is suspected of SCI.Special considerations are indicated for children less than 7 years old.The ABCs should be implemented as a primary resuscitative effort.Acute respiratory and hemodynamic failure after SCI should also require careful management at the scene.All efforts are aimed primarily at reducing the morbidity associated with acute SCI and increasing the survival rate of patients with SCI.

Objective To investigate the effect of problem- based learning (PBL) combined with evidence- based medicine (EBM) on clinical teaching for postgraduates of spinal cord injury rehabilitation. Methods Postgraduates who studied in our ward between April 2010 to March 2012 were enrolled as control group (n=12) and received traditional teaching. Postgraduates who studied in our ward between April 2012 to March 2014 were enrolled as test group (n=12) and received PBL combined EBM in addition. Their achievement of academic and practical (case analysis) tests were compared, and they were investigated with questionnaire of satisfaction. Results There was no significant difference between the groups in achievement of academic and practical (case analysis) tests (P>0.05). The score of progressive knowledge was significantly higher in the test group than in the control group (P<0.01). The results of questionnaire showed that the level of literature retrieval, English, self-learning and analyzing-summarizing improved more in the test group than in the control group (P<0.05). There was no significant difference between the groups in terms of improvement of clinical thinking, nor of the satisfaction about teacher and teaching method (P>0.05). Conclusion PBL combined with EBM can improve the teaching for postgraduates majored in spinal cord injury rehabilitation.
