BACKGROUND: Free radicals are produced during ischemia, which can strengthen activity of lipid peroxidation; induce lesion of cell and cellular barrier, result in necrosis or apoptosis of neurons; and aggravate edema of ischemic cerebral tissue.OBJECTIVE: To observe the effects of polydatin (PD) on free radicals, lipid peroxidation, water contents and pathological morphology of brain tissue in rats with focal cerebral ischemia so as to explore its protective mechanisms.DESIGN: A randomized controlled trial.SETTING: Intensive Care Unit, Second Affiliated Hospital, Chongqing University of Medical Sciences; Pediatric Research Institute, Children's Hospital Chongqing University of Medical Sciences.MATERIALS: The experiment was carried out at the Pediatrics Medicine Institute of Chongqing Medical University from October 2001 to July 2002.Totally 48 healthy adult male Wistar rats were divided into 3 groups randomly,with 16 in each group. Group Ⅰ was sham-operated group: rats were anaesthetized, the right common carotid arteries were separated instead of being occluded. Group Ⅱ was ischemia group: to establish the right middle cerebral artery occlusion model of rats. Group Ⅲ was PD pretreatment group: polydatin (6 g/L, 12 mg/kg) were intravenously administrated 30 minutes before the onset of ischemia. Saline substituted for PD, besides, were intravenously administrated with the same way and dosage on Group Ⅰ, Group Ⅱ and Group Ⅲ.The rats were decapitated and the brains were immediately removed after cerebral ischemia 2 hours. In each group, 8 rats were chosen to be determined water contents of brain tissue, the other 8 rats were chosen to be determined levels of lipid peroxidation and free radicals in brain tissue.METHODS: According to the formula which was: wet weight-dry weight/wet weight×100%, water content of cerebral tissue was assayed. Superior liquid was taken to assay MDA with spectrophotometer thiobarbituric acid method (TBA) method, SOD activity assayed by xanthiue oxidase enzyme method, the activities of GSH-Px, CAT and NOS determined by colorimetry,the amount of protein determined by the method of Lowry. All the procedures were carried out strictly according to the instruction.malonaldehyde (MDA) and activities of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), catalase (CAT) and nitric oxide synthase chemia, contents of SOD, GSH-Px and CAT in cerebral tissue of PD group were obviously higher than those of ichemia model group [(226.43±8.69),(193.37±11.14) NU/mg; (244.38±12.34), (211.71±16.50) μkat/g; (59.85±9.67),water in cerebral tissue of PD group were obviously lower than those of ichemia model group [(6.38±0.54), (8.63±0.78) μmol/g; (78.72±0.43)%,tivity in ischemic tissue but the results were similar to that in ischemia model group [(12.00±1.00), (12.84±1.17) μkat/g, P ＞ 0.05] in brain tissue.ed that PD alleviated the ischemia edema of cerebral ischemia.CONCLUSION: PD can alleviate the reaction of lipid overoxidation, improve the activities of antioxidant-enxymes, reduce ischemia brain edema,protect the function of cell member, bring down the damage to ischemia neurons. It shows that PD has significant cerebral protective role on focal ischemia brain damage.

Objective To observe destruction of tibias created in ablating of the swine limbs in vivo with radiofrequency,the influence on the surrounding organization structure,and the repair process of lesions for treating bony tumor.Methods There were eight pigs included in the first part of the experiment.RFA was performed under DSA guidance at the same position of the diaphysis and the upper end of their right tibias in hind leg during anesthesia,then X-ray and CT examinations were performed at different time points after RFA,and subsequently the pigs were executed by depth anesthesia.Control specimens,specimens of the immediate time,the third day,the tenth day,the twenty-fourth day,the fifth week,the eighth week,the twelfth week after RFA were obtained at the diaphysis and the upper end of their tibias.X-ray and CT examinations of these specimens were performed.These specimens were observed both by naked eye and under microscope.The observation included the general state of the laboratory animals after RFA,the configuration of RFA lesions in the gross specimen and the corresponding histologic changes,the boundary of necrosis in RFA lesions and the corresponding boundary of the gross specimen.There were sixteen pigs in the second part of the experiment.RFA was performed at the same position of the diaphysis and the upper end of their right and left tibias in hind leg during anesthesia,and the pigs were immediately executed by depth anesthesia after RFA to get thirty-two capitulum specimens and thirty-two diaphysis specimens.The scope of necrotic tissue in RFA lesions was observed and measured.The border and scope of necrotic tissue in RFA lesions were observed.Major axis,minor axis,and necrosis volume were measured.The independent sample t test was employed to compare the volume of necrotic tissues between capitulum and diaphysis.The one sample t test was employed to analyze volume of necrotic tissue among capitulum,diaphysis and the standard data.Results No accidental death of the animals occured in the first experimental.The loss of neurological function of the hind leg did not happen.Coagulation necrosis in cancellous bone of capitulum and marrow of diaphysis lesions created in ablating was observed.On 3th to 10th day after RFA,inflammatory cells infiltrated in hemorrhage tape and then granulation tissues formed.Granulation tissues replaced necrotic bone gradually from outside to inside.Low density band was showed on images of X-ray and CT examination in the specimen of 10th day,and it extended inward.The immature bone was observed in fibrous tissue sited at the edge of lesions,which appeared as sclerosis on X-ray and CT examination.The scope of necrotic tissue in RFA lesions included coagulation necrosis and hemorrhagic zone of its periphery.The dead bone and secondary pathological fracture appeared in two of eight pigs.RFA hardly damaged compact bone in the diaphysis,but the damage of soft tissue was observed outside the compact bone.In the second experiment,the shape of lesions in cancellous bone of capitulum was ellipsoid,with long axis of(2.59±0.21) cm,minor axis of(2.15±0.10) cm,and volume of(6.34±0.27) cm3.The shape of lesions in the diaphysis of tibias was ellipsoid,with long axis of(4.53±0.20) cm,minor axis of(1.71 ±0.22) cm,and volume of(7.14±0.36) cm3.There was significantly difference of necrosis volume between the capitulum and diaphysis lesions,(t=2.011,P＜0.05).The virtual necrosis volume of the capitulum and diaphysis lesions was significantly different from the presumed volume with RFA instrument(t=-613.371,-295.878,P＜0.01).Conclusion Cancellous bone of the capitulum can be damaged by RFA,but the compact bone of the diaphysis can hardly be damaged.The intact compact bone can be helpful to protect the surrounding soft tissues.X-ray and CT examination can be used in the evaluation of curative effect of RFA for treating bone tumors.Pathological fracture of the diaphysis may appear after RFA.

Objective To investigate the outcomes of unselected peripheral T cell lymphoma (PTCL) patients treated with in-tensive first-line chemotherapy with high-dose therapy followed by autologous stem cell transplantation (ASCT).Methods Here a nonrandom study was reported for 23 PTCL patients treated with first-line intensive chemotherapy followed by autologous stem cell trans-plantation and 23 PTCL patients treated with conventional chemotherapy during January in 2000 to 2011 .All patients had received E-CHOP for 6~8 cycles, and autologous stem cell transplantation group was administrated with intensive chemotherapy followed by ASCT after complete remission or partial remission .Results There was no statistically significant difference in short-term therapeutic effect between two groups( P >0.05), but the 5-year overall survival(OS) of autologous stem cell transplantation group( 58%) was higher than conventional chemotherapy group , as well as 5-year disease-free survival time (DFS) (45%in autologous stem cell transplanta-tion group, and 21%in conventional chemotherapy group ) with both statistical significance ( P <0.05).Only the incidence of Ⅳ° myelosuppression in autologous stem cell transplantation group ( 100%) was higher than that in conventional chemotherapy group ( 13%) ( P <0.01 ) .Conclusions First-line intensive chemotherapy followed by autologous stem cell transplantation for peripheral T cell lymphoma was quietly safe utility , it was better than conventional chemotherapy which would be considered as first -line method.

OBJECTIVE: To evaluate the effect of aerobic exercise on genome expression in human skeletal muscle. METHODS: Six healthy sedentary elderly men aged (66+9) years were selected from military cadre retirement centers and after exercise. Testing indices included height, weight, vital capacity, step index and maximal oxygen uptake. Needle biopsies were obtained from the skeletal muscle before and after the last training. Total RNA extracted from the samples was hybridized to Affymetrix U 133A platform, the gene expression datum was analyzed.RESULTS: Aerobic exercise was shown to improve cardiorespiratory function and reduce body fat of elder subjects. It could alter the genome expression in human skeletal muscle, the number of genes that passed filtering criteria was 725. The most differently expressed genes (n=20) were investigated in this study, in which there were 3 upregulated and 17 downregulated. According to gene function annotations, the differential genes were classified into 8 categories which concerned cellular component and biological process, Kyoto Encyclopedia of Genes and Genomes (KEGG) searching showed 4 genes' metabolism pathway. CONCLUSION: Systematic aerobic exercise upregulates expression of enzyme genes concerning tricarboxylic acid cycle, and downregulates expression of genes conceming muscle protein synthesis and sphingolipid. It is suggested that aerobic exercise is good to protect human nerves' integrity, exerts positive action on anti-aging and accelerate the aerobic metabolism of lipid materials in vivo.

Using cDNA from Rehmannia glutinosa leaf as template, a 972 bp fragment of expansin gene which containing a 762 bp ORF that encoded 253 amino acids, was cloned, named RgEXPA10, which GenBank accession number for this gene is KF011918. A 1 207 bp genomic sequence of RgEXPA10 was amplified by PCR with leaf DNA as template, sequencing analysis revealed that three exons and two introns in RgEXPA10 genomic sequence, and which GenBank accession number is KF011919. Molecular and bioinformatic analyses indicated that RgEXPA10 protein have DPBB_1 and Pollen_allerg_1 domain, also including a 26 aa nuclear localization signal and a 19 aa transmembrane region. Phylogenetic analysis revealed that RgEXPA10 showed the highest homology with AtEXPA8 among the 26 α-expansins in Arabidopsis thaliana. However, the RgEXPA10 indicated the highest homology with the expansin from Solanum lycopersicum among 22 plant species. Expression patterns using qRT-PCR analysis showed that RgEXPA10 mainly expressed in unfolded leaf, followed by the tuberous root at stage of expanding period, and rarely expressed in senescing leaf. And RgEXPA10 showed higher expression level in tuberous root at 60 and 90 days after emergence. The transcription level of RgEXPA10 significantly reduced under all the three stresses including continuous cropping conditions, salinity and waterlogging. This study will lay foundations for molecular function in development and regulation of different stresses for R. glutinosa.
