Intravenous administration of adenosine triphosphate and phosphocreatine combined with fluoxetine in major depressive disorder: protocol for a randomized, double-blind, placebo-controlled pilot study.

Background: Major depressive disorder (MDD) is a common psychiatric disorder. With systematic antidepressant treatment, 50-75% of patients have a treatment response but require 4-6 weeks to have their symptoms alleviated. Therefore, researchers anticipate the development of novel fast-acting antidepressants.

Repetitive transcranial magnetic stimulation for depression after basal ganglia ischaemic stroke: protocol for a multicentre randomised double-blind placebo-controlled trial.

Introduction: Studies suggest that repetitive transcranial magnetic stimulation (rTMS) is effective for the treatment of depression and promotes the repair of white matter. This study aims to assess the effectiveness of rTMS in treating depression after basal ganglia ischaemic stroke and to examine whether such effects are related to restoration of white matter integrity.

Methods And Analysis: Sixty-six participants will be recruited from Zhujiang Hospital, Nanfang Hospital and Sichuan Bayi Rehabilitation Hospital and randomised in a 1:1 ratio to receive active rTMS treatment or sham rTMS treatment in addition to routine supportive treatments.

[Transfection of pEGFP-C2 in brain mediated by targeting liposome P-MMA-DOSPER].

This research tried improving the specificity and efficiency of gene transfection in gene therapy and tried making the liposome a better gene transfer vector to brain by use of the monoclonal antibody (anti-Lex/SSEA-1)-mediated targeting of liposome. The derivatized monoclonal antibody was conjugated to the liposome DOSPER to form the targeting liposome P-MMA-DOSPER. Then, the pEGFP-C2 encapsulated in P-MMA-DOSPER or DOSPER was injected into the lateral ventricle of SD rats respectively, and the brains were taken for frosted slice 1, 3, 7 or 14 days later.

[Psychological stress in the earthquake survivors: the psychological aftermath of the Wenchuan earthquake].

Objective: To investigate the psychological stress in the survivors of the May 12, 2008 Wenchuan earthquake transferred to Guangzhou for treatment, and explore the association between the psychological stress and the physical injuries related to the earthquake to promote both the physical and psychological recoveries of the survivors.

Methods: Fifty-five earthquake survivors, including 27 with 28 without physical injuries, were transferred in our hospital 1 week after the earthquake. The Posttraumatic Stress Disorder (PTSD) Checklist-Civilian version (PCL-C) and the Self Reporting Questionnaire (SRQ) were used to investigate the psychological stress in these survivors.

[Morphological characteristics of internal carotid artery atherosclerotic lesions in digital subtracted angiography].

Objective: To illustrate the morphological characteristics of atherosclerotic lesions of the internal carotid artery.

Methods: The morphological characteristics of cervicocerebral atherosclerotic lesions in digital subtracted angiography were retrospectively reviewed in 120 cases.

Results: Totally 217 atherosclerotic lesions were detected.

Modification of the brain-derived neurotrophic factor gene: a portal to transform mesenchymal stem cells into advantageous engineering cells for neuroregeneration and neuroprotection.

Multipotential mesenchymal stem cells (MSCs) are ideal seed cells for recruiting the loss of neural cells due to their strong proliferative capacity, easy acquisition, and considerable tolerance of genetic modifications. After transduction of brain-derived neurotrophic factor (BDNF) gene via recombinant retroviral vectors into the human MSCs, nearly 100% of cells expressed BDNF (which were therefore transformed into BNDF-MSCs) as detected by immunocytochemistry, and the quantity of BDNF in the culture medium was increased by approximately 20,000-fold. In spite of the genomic integration of an exogenous gene, BDNF-MSCs did not present any structural aberration in the chromosomes.
