Calbindin D28K expression in relation to granule cell dispersion, mossy fibre sprouting and memory impairment in hippocampal sclerosis: a surgical and post mortem series

Reorganisation of the dentate gyrus, including granule cell dispersion (GCD) and mossy fibre sprouting, typically accompany hippocampal sclerosis (HS) in temporal lobe epilepsy. Calbindin (CB) expression in granule cells increases during infancy, influences granule cell excitability, vulnerability to excitotoxicity in addition to important physiological functions in memory. Our aim was to study CB patterns in relation to dentate gyrus re-organisation, epilepsy history and memory function. Forty-five surgical cases and 11 post mortems were examined from patients with drug-resistant epilepsy in addition to three post mortem controls. In the surgical cases, CB expression, and the degree of GCD and mossy fibre sprouting were measured. In post mortem cases, CB expression was assessed in relation to the pattern of HS along the rostral-caudal axis of the hippocampus, and compared to PM controls. Three patterns were identified. In Group 1 (40%), the most dispersed granule cells were CB-positive and basal cells negative imitating developmental patterns. In Group 2 (47%), normal CB expression was retained and in Group 3 (13%), CB was predominantly lost in granule cells. These patterns correlated with GCD, the presence of mossy fibre sprouting and the pattern of HS. Group 1 was associated with early onset of seizures but not independently predictive of outcome. In post mortem cases, altered CB expression lateralised to the side of HS and persisted despite seizure remission in some patients. No significant correlation between CB expression and memory function was identified. CB expression patterns in HS may indicate developmental dysmaturation and are associated with the extent of GCD and mossy fibre sprouting in HS. The functional significance of CB loss, in terms of epileptogenesis and effects on memory, remain uncertain.

Effect of Yifei Huoxue Granule (益肺活血颗粒) on the proliferation of rat pulmonary artery smooth muscle cells upon exposure to chronic hypoxic conditions in vitro

Objective:To investigate the inhibitory effect of Yifei Huoxue Granule （益肺活血颗粒,YFHXG） on the hypoxia-induced proliferation of rat pulmonary artery smooth muscle cells（PASMCs） and its mechanism of decreasing pulmonary arterial pressure.Methods:Twenty male Sprague-Dawley（SD） rats were randomly divided into four groups:saline,and 0.66,3.30 and 16.50 g/kg of YFHXG groups,the saline and different concentrations of YFHXG were given twice daily for 7 days,respectively.Serum-pharmacology method was used in the preparation of YFHXG serum.Tissue block anchorage was employed in the primary culture of rat PASMCs.The PASMCs were randomly divided into normoxia group,hypoxia group,and hypoxia+YFHXG group （0.66,3.30 and 16.50 g/kg doses of YFHXG-treated serum groups,exposed to hypoxic condition）.PASMCs in normoxia and hypoxia group were cultured with saline serum,hypoxia+YFHXG groups were cultured with different concentrations of YFHXG serum.Cell viability was assessed with 3-（4,5-dimethylthiazol-2-yl）-2,5- diphenyltetrazolium bromide（MTT） assay.Cell cycle was analyzed using flow cytometry.In addition,hypoxia inducible factor-1-alpha（HIF-1α） protein expression was evaluated by immunocytochemistry analysis,the concentration of intracellular reactive oxygen species（ROS） and Ca²⁺ were determined by laser scanning confocal microscopy（LSCM）.Results:MTT assay and flow cytometry showed that hypoxia could directly activate the proliferation of PASMCs,while YFHXG dose-dependently inhibited hypoxia-induced proliferation of rat PASMCs.Immunocytochemistry showed that hypoxia enhanced HIF-1αprotein expression,and LSCM showed that hypoxia significantly increased intracellular ROS and Ca²⁺,while YFHXG decreased the expression of HIF- 1αand attenuated the hypoxia-induced increase in intracellular concentration of ROS and Ca²⁺.Conclusions: YFHXG could inhibit hypoxia-induced proliferation of rat PASMCs,which may decrease pulmonary arterial pressure and vascular remodeling.The anti-hypoxia effect of YFHXG may be explained by its regulation of HIF-1α expression and of the levels of intracellular ROS and Ca²⁺.
