Hot-water extracts were prepared from fresh tea leaves and fractionated by DEAE-cellulose DE-52 column chromatography to yield one unexplored polysaccharide-conjugate fraction TPC-L (tea polysaccharide conjugates). Chemical components, molecular weight and its distribution, water vapor sorption properties, zeta potentials and optical characteristics of TPC-L were investigated. As compared with injured cell group, the two dosages of TPC-L (150 and 300 μg/mL) were discovered to possess remarkably protective effect on human umbilical vein endothelial cells against impairments induced by high glucose in a dose-dependent manner (p < 0.05, p < 0.001, respectively). Compared with group NC (normal control), the ingestion of 40 mg/kg of TPC-L could significantly reduce blood glucose levels of normal mice ingesting starch, and significant difference of AUC (area under the curve of blood glucose) and ΔAUC (p < 0.05, p < 0.01) at the postprandial time point of 0.5 and 1.0 h were observed. The three dosages of TPC-L (10, 40 and 160 mg/kg) did not significantly lower postprandial blood glucose levels of normal mice ingesting glucose. TPC-L could improve starch tolerance to prevent impaired glucose tolerance (IGT) from developing into diabetes as well as protective effects on HUVE cells against impairments induced by high glucose It was suggested that TPC-L improved IGT through its capability of inhibition on digestive enzymes. © 2014 Elsevier Ltd.

Traffic Injury Prevention | Year: 2016

ABSTRACT: Objective: Road traffic accidents are the leading health threat to children and cause significant long-term mental health problems. This study aimed to characterize posttraumatic stress disorder (PTSD) in children suffering from road traffic injuries (RTIs) in Wenzhou, China. Methods: We conducted a retrospective study of 537 children (aged 1 to 13 years old) with RTIs. The epidemiological features, PTSD incidence, clinical manifestation, and risk factors were analyzed based on a customized PTSD risk factor questionnaire. The outcome factors were also evaluated by means of the logistic regression method. Results: The PTSD incidence was 24.77% in children with RTIs. The incidence of PTSD was related to the personality, family environment, and family care of the children. It was found that early psychological intervention and reasonable family care from the family might promote physical and mental welfare as well as contribute to the development of more effective treatments to prevent PTSD. Conclusion: For susceptible children, in addition to dealing with the somatic injury, psychological intervention and family care should be carried out as early as possible. © 2015 Taylor & Francis Group, LLC.

Dopaminergic neurons loss in the substantia nigra (SN) and dopamine (DA) content loss in the striatum correlate well with disease severity in Parkinsons disease (PD). Brain-derived neurotrophic factor (BDNF) is a member of neurotrophin family and is necessary for the survival and development of DA neurons in the SN. Deficits in BDNF/TrkB receptors signaling contribute to the dysfunction of PD. Deoxygedunin, a derivative of gedunin produced from Indian neem tree, binds TrkB receptor and activates TrkB and its downstream signaling cascades in a BDNF-independent manner, and possesses neuroprotective effects invitro and invivo. In this study, we tested the neuroprotective effects of deoxygedunin in 6-hydroxydopamine (6-OHDA)-lesioned rat model and 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced mice model of Parkinsons disease. Rats were treated with deoxygedunin 5mg/kg (i.p.) for one month started two weeks before 6-OHDA lesion (pre-treatment), or for two weeks right after lesion (post-treatment), with isovolumetric vehicle as control and normal. Mice were given deoxygedunin 5mg/kg (i.p.) for 2 weeks and administrated with MPTP twice at the dose of 20mg/kg (i.p.) on day 7. The results revealed that pretreatment with deoxygedunin improved PD models behavioral performance and reduced dopaminergic neurons loss in SN, associated with the activation of TrkB receptors and its two major signaling cascades involving mitogen-activated protein kinase (MAPK) and phosphatidylinositol 3-kinase (PI3K). Thus, our current study indicates that deoxygedunin, as a small molecule TrkB agonist, displays prominent neuroprotective properties, providing a novel therapeutic strategy for treating Parkinsons disease.

Multiple players are involved in motor and sensory dysfunctions after spinal cord injury (SCI). Therefore, therapeutic approaches targeting these various players in the damage cascade hold considerable promise for the treatment of traumatic spinal cord injury. Soluble epoxide hydrolase (sEH) is an endogenous key enzyme in the metabolic conversion and degradation of P450 eicosanoids called epoxyeicosatrienoic acids (EETs). sEH inhibition has been shown to provide neuroprotective effects upon multiple elements of neurovascular unit under cerebral ischemia. However, its role in the pathological process after SCI remains unclear. In this study, we tested the hypothesis that sEH inhibition may have therapeutic effects in preventing secondary damage in rats after traumatic SCI. sEH was widely expressed in spinal cord tissue, mainly confined to astrocytes, and neurons. Administration of sEH inhibitor AUDA significantly suppressed local inflammatory responses as indicated by the reduced microglia activation and IL-1 expression, as well as the decreased infiltration of neutrophils and T lymphocytes. Meanwhile, reactive astrogliosis was remarkably attenuated. Furthermore, treatment of AUDA improved angiogenesis, inhibited neuron cells apoptosis, alleviated demyelination and formation of cavity and improved motor recovery. Together, these results provide the first in vivo evidence that sEH inhibition could exert multiple targets protective effects after SCI in rats. sEH may thereby serve as a promising multi-mechanism therapeutic target for the treatment of SCI.

In order to explore the role of acetylcholine in the pathogenesis of Parkinson's disease (PD), the changes in the concentration of acetylcholine (Ach) in the striatum, the apoptosis of substantia nigra cells, the ultrastructure and the changes of Nissl cells in rats during the morbidity of PD, and the corresponding behaviors in rats with PD were observed. Rat PD model was established by using the modified Thomas method. Eighty-one rats were randomly divided into normal control, sham operation and PD groups and their behavior features were observed at post-operative day (POD) 7, 14 and 21 as three subgroups (n=9 each). The concentration of Ach in the striatum was determined by using high-performance liquid chromatography. The apoptosis of substantia nigra cells was assayed by using TUNEL method. The ultrastructural changes in the substantia nigra were observed under the electron microscopy, and the survival of neurons in the substantia nigra area was examined by using Nissl staining. In PD group at POD 7 to 21, the damage in the substantia nigra area was gradually aggravated, the concentration of Ach, apoptosis rate and turns of rotation were gradually increased, and the number of Nissl cells was gradually reduced over the time as compared with the normal control and sham operation groups (all P<0.05). It was concluded that there exist dynamic changes in Ach concentration, ethology and apoptosis of the substantia nigra cells during the morbidity of PD, suggesting the contribution of apoptosis to the morbidity of PD, and critical role of Ach in the pathogenesis of PD. © Huazhong University of Science and Technology and Springer-Verlag Berlin Heidelberg 2012.

Recent studies suggest that angiogenesis and vascular endothelial growth factor (VEGF) are involved in the pathophysiology of epilepsy. However, relatively little data are available linking placenta growth factor (PIGF) with epilepsy. In this study, we assessed concentrations of PIGF in cerebrospinal fluid (CSF) of 60 epileptic patients and 24 non-seizure subjects using sandwich enzyme-linked immunosorbent assays. Epileptic patients in general had higher concentration of CSF-PIGF than controls (7.95 ± 0.88 ng/l vs. 5.87 ± 0.79 ng/l, P < 0.01). CSF-PIGF level in secondary epileptic patients (8.59 ± 1.26 ng/l) was higher than that in idiopathic epileptic patients (7.62 ± 0.20 ng/l) (P < 0.05). In idiopathic epilepsy, CSF-PIGF level in patients with high seizure frequency was higher than those in patients with low seizure frequency and seizure-free in recent 3 years (7.78 ± 0.23 ng/l vs. 7.49 ± 0.09 ng/l and 7.59 ± 0.10 ng/l, P < 0.05). Concentration of CSF-PIGF in patients with a disease duration of >5 years was higher than those in patients with durations of 1-5 years and <1 year (7.72 ± 0.20 ng/l vs. 7.52 ± 0.09 ng/l and 7.41 ± 0.07 ng/l, P < 0.05). These results indicate that preexisting brain damage, seizure frequency and disease duration are important factors contributing to elevated PIGF. © Springer Science+Business Media, LLC 2011.

Studies have shown that neurofibromin (NF1) restricts GABA release at inhibitory synapses and regulates dendritic spine formation, which may play an important role in temporal lobe epilepsy (TLE). NF1 expression was detected by double-label immunofluorescence, immunohistochemistry, and western blot analysis in the brains of pilocarpine-induced epilepsy model rats at 6h, 24h, 72h, 7days, 14days, 30days, and 60days after kindling. NF1 was localized primarily in the nucleus and cytoplasm of neurons. NF1 protein levels significantly increased in the chronic phase (from 7days until 60days) in this epileptic rat model. After NF1 expression was knocked down by specific siRNA, the effects of kindling with pilocarpine were evaluated on the 7th day after kindling. The onset latencies of pilocarpine-induced seizures were elevated, and the seizure frequency and duration were reduced in these rats. Our study demonstrates that NF1 promoted seizure attacks in rats with pilocarpine-induced epilepsy.

This study aimed to assess the efficacy of a rural community-based integrated intervention for early prevention and management of chronic obstructive pulmonary disease (COPD) in China. This 18-year cluster-randomized controlled trial encompassing 15 villages included 1008 patients (454 men and 40 women in the intervention group [mean age, 54 10 years]; 482 men and 32 women in the control group [mean age, 53 10 years]) with confirmed COPD or at risk for COPD. Villages were randomly assigned to the intervention or the control group, and study participants residing within the villages received treatment accordingly. Intervention group patients took part in a program that included systematic health education, smoking cessation counseling, and education on management of COPD. Control group patients received usual care. The groups were compared after 18 years regarding the incidence of COPD, decline in lung function, and mortality of COPD. COPD incidence was lower in the intervention group than in the control group (10% vs 16%, <0.05). A decline in lung function was also significantly delayed in the intervention group compared to the control group of COPD and high-risk patients. The intervention group showed significant improvement in smoking cessation compared with the control group, and smokers in the intervention group had lower smoking indices than in the control group (350 vs 450, <0.05). The intervention group also had a significantly lower cumulative COPD-related death rate than the control group (37% vs 47%, <0.05). A rural community-based integrated intervention is effective in reducing the incidence of COPD among those at risk, delaying a decline in lung function in COPD patients and those at risk, and reducing mortality of COPD.
