Objective To determine if there is an early developmental resistance to seizure-induced hi ppocampal damage. Methods Five daily pentylenetetrazol-indu ced convulsions in immature rats beginning at postnatal day P10,P60 groups.In b oth groups, the latency of seizure, the latency of Ⅳ/Ⅴ grade, the lasting time of seizure and mortality of rats after seizure were used to measure sensitivity of seizure or the resistance to brain damage. Conventional histopathological me thod was utilized to observe morpbological changes and cell counting of dentate granule cells, CA 3,CA 1 and hilar neurnns. Timm histochemical technique was a dopted to study mossy fiber sprou- ting.Results 1.In the both groups(P10,P60),there were significant differences in the latency of seizure (1.07?0.55 vs 8.27?1.48 P

Objective To compare the therapeutic effect of routine dose of calcitriol and large dose impulsion therapy on hemodialysis patients with secondary hyperparathyroidism(SHPT). Methods 48 uremic hemodialysis patients were divided into group A(routine group, n = 22) and group B(control group, n = 21 ). In group A,22 pa-tients were administered with calcitriol for 6 months at the dosage of 0.25~0.5μg/d,adding calcium agents simul-taneously;the patients in group B were not given calcitriol for economic reason. In group C,21 patients were given calcitriol twice a week at the dosage of 2μg/time after hemodialysis for 3 months. Results Comparing to group B,serum PTH,AKP in group A had no significant difference,but serum hypocalcium and hyperphasphate were partly corrected,symptoms of bone pain, muscular convulsion and akin pruriter were improved. Comparing to group A,serum hypocalcium and hyperphasphate in group C were corrected, serum PTH, AKP were significantly decreased( t=2.031,P<0.05;t =3.317,P<0.001),and no hypercalcium oecurred. Conelosion Routine dose of calcitriol can not control uremic-SHirr,while impulsion therapy with lower dose oral calcitriol is effective and safe.

9.Proteomic analysis of human ovarian cancer cell lines and their platinum-resistant clones
Chinese Journal of Obstetrics and Gynecology 2000;0(09):-
Objective To perform comparative proteomic analysis of human ovarian cancer cell lines for detecting platinum-resistance associated proteins.Methods The total proteins of two sensitive (SKOV3 and A2780)and four resistant(SKOV3/CDDP,SKOV3/CBP,A2780/CDDP and A2780/CBP) human ovarian cancer cell lines were separated by two-dimensional gel electrophoresis(2-DE).The differentially expressed proteins were analyzed using image analysis software,stained with Coomassie Brilliant Blue,then identified using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry(MALDI-TOF-MS)and database searching.The mRNA and protein levels of the differentially expressed protein which was most significant in all of the four resistant cell lines were validated by RT-PCR and western blotting,respectively.Results Five proteins were found to be significant in four cell lines. Annexin A3 and destrin were up-regulated and nicotinamide-adenine dinucleotide phosphate(NADP)- dependent isocitrate dehydrogenase 1 was down-regulated in all the four resistant samples.Glutathione transferase omega 1 had an increased expression in the other three resistant cell lines except for SKOV3/CBP in which its expression was not changed.However,cofilin 1 represented a different trend.In the two resistant sublines of SKOV3,eofilin 1 had a down-regulation,but it had an up-regulation in the cell lines induced from SKOV3.The expression of annexin A3 was up-regulated by 3-20 fold and the results of RT- PCR and western blotting showed complete consistency with that by 2-DE.Conclusions Proteomic techniques are useful to the identification of the resistance-associated proteins in ovarian cancer platinum- resistant cell lines and five candidates have been found.The five differential proteins might become hopeful candidate biomarkers for resistance.

ObjectiveTo observe the protective effect of tetrahydroxystilbene glucoside (TSG) on rats' hippocampal neuronal damage induced by glutamate (Glu) in the culture.MethodsHippocampus was isolated from newborn SD rats and dispersedly cultured in the medium for 9 days. Neurons were incubated with TSG (5—100μmol/L) for 24h, the cells were washed twice with Lock's solution without Mg2+,then Glu 500 μmol/L was added. Thirty min later, the reaction was terminated by washing the monolayer cells twice with the Lock's solution and then cultures were kept at 37℃ for 24h. Cell viability was measured by MTT method and cell membrane damage was determined by LDH leakage; with Fluo-3/AM as an intracellular calcium indicator and added into the bathing medium, fluorescent intensity of intracellular free calcium were observed through laser scanning confocal microscopy (LSCM).ResultsAfter the treatment with 5—100μmol/L TSG for 24h, the decrease of cell viability and the increase of LDH leakage caused by Glu was obviously resisted dose dependently. TSG inhibited increase of Ca2+ in cytoplasm, compared with model group.ConclusionTSG can significantly promote the cell viability and reduce the cell membrane damage in Glu treating hippocampal neurons. The neuroprotective activities of TGS is mediated by inhibiting Ca2+ overload in cytoplasm.
