Parkinson's disease (PD) is a common neurodegenerative disorder affecting 1% of the population by the age of 65 years and 4-5% of the population by the age of 85 years. PD affects functional capabilities of the patient by producing motor symptoms and nonmotor symptoms. Apart from this, it is also associated with a higher risk of cognitive impairment that may lead to memory loss, confusion, and decreased attention span. In this study, we have investigated the effect of fenofibrate, a PPAR-α agonist in cognitive impairment model in PD. Bilateral intranigral administration of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) (100 µg/1 µL/side) produced significant cognitive dysfunctions. Fenofibrate treatment at 10, 30, and 100 mg/kg for twenty-five days was found to be neuroprotective and improved cognitive impairment in MPTP-induced PD model as evident from behavioral, biochemical (MDA, GSH, TNF-α, and IL-6), immunohistochemistry (TH), and DNA fragmentation (TUNEL positive cells) studies. Further, physiologically based pharmacokinetic (PBPK) modeling study was performed using GastroPlus to characterize the kinetics of fenofibric acid in the brain. A good agreement was found between pharmacokinetic parameters obtained from the actual and simulated plasma concentration-time profiles of fenofibric acid. Results of this study suggest that PPAR-α agonist (fenofibrate) is neuroprotective in PD-induced cognitive impairment.

“…By reading the full text of the remaining 208 articles which reported the efficacy of BBA in animal models of focal cerebral ischemia, 54 studies were excluded because the outcome measure was neither neurological function score (NFS) nor infarct volume (IV); 48 studies were excluded because other forms of acupuncture or TCM were used in control group; 34 were excluded because of combination with body acupunctures; 18 studies were removed due to the deficiency of useful data and the problem of duplicate publication. Ultimately, 54 eligible studies were identified (Figure 1)34353637383940414243444546474849505152535455565758596061626364656667686970717273747576777879; Li JA, unpublished Master's thesis, 2005; Wang C, unpublished Master's thesis, 2005; Jin JF, unpublished PhD thesis, 2005; Luo T, unpublished Master's thesis, 2006; Chen X, unpublished Master's thesis, 2007; Ding J, unpublished Master's thesis, 2007; Wang EL, unpublished PhD thesis, 2008; Wu HY, unpublished PhD thesis, 2010.…”

Acupuncture for stroke has been used in China for over 2,000 years and nowadays is increasingly practiced elsewhere in the world. However, previous studies had conflicting findings on the results of acupuncture. Here, we conducted a systematic review and meta-analysis to assess the current evidence for the effect of Baihui (GV20)-based scalp acupuncture in animal models of focal cerebral ischemia. Six databases from the inception of each database up to June 2013 were electronically searched. Primary outcomes were infarct size and neurobehavioral outcome. Ultimately, 54 studies involving 1816 animals were identified describing procedures. Meta-analysis results showed that twelve studies reported significant effects of Baihui (GV20)-based scalp acupuncture for improving infarct volume compared with middle cerebral artery occlusion group (P < 0.01), and thirty-two studies reported significant effects of Baihui (GV20)-based scalp acupuncture for improving the neurological function score when compared with the control group (P < 0.01). In conclusion, Baihui (GV20)-based scalp acupuncture could improve infarct volume and neurological function score and exert potential neuroprotective role in experimental ischemic stroke.

Cerebral Blood Flow and Apoptosis-Associated Factor with Electroacupuncture in a Traumatic Brain Injury Rat Model

Objective Electroacupuncture (EA) has been widely used for treatment of stroke, but there is little information on the effect of EA on the neuroprotective function in traumatic brain injury (TBI). The aim of the present study was to investigate the protective effects and mechanisms of EA treatment in a TBI rat model. Methods Male Sprague–Dawley rats were randomly divided into four groups: sham operation, TBI control, TBI+EA treated for 30 min or TBI+EA treated for 60 min. The animals were treated with EA immediately after TBI. The EA was applied at acupuncture points GV20, GV26, LI4 and KI1 with a dense-dispersed wave, frequencies of 0.2 and 1 Hz, and amplitude of 1 mA for 30 or 60 min. Regional blood flow, cell infarction volume, extent of neuronal apoptosis, expression of cell apoptosis-associated factor transforming growth-interacting factor (TGIF) were studied, and functional outcome was assessed by running speed test. All tests except regional blood flow were performed 72 h after TBI onset. Results Immediately after TBI, compared with the TBI control groups, the regional blood flow was significantly increased by EA treatment for 60 min. Compared with the TBI controls 72 h after TBI, the TBI-induced run speed impairment, infarction volume, neuronal apoptosis and apoptosis-associated TGIF expression were significantly improved by EA treatment. Conclusions The treatment of TBI in the acute stage with EA for 60 min could increase the regional blood flow and attenuate the levels of TGIF in the injured cortex, might lead to a decrease in neuronal apoptosis and cell infarction volume, and might represent one mechanism by which functional recovery may occur.

Abstract: Scalp acupuncture can attenuate cerebral ischemia-reperfusion injury, improve neurofunctional rehabilitation and suppress leukocyte infiltration in rats by decreasing the contents of COX-2 and NF-kappaB and enhancing TGF-beta1 expression in brain tissues.
