Objective:To investigate the neuro psychological characteristics and their change in leukoaraiosis(LA).M ethods:29 asymotamatic LA sub jects and 25 normal controls were compared on a comprehensive neuropsychological test battery,which included Revised Visual Retention Test(VRT),Wechsler Adult I n telligence Scale-Revised in China(WAIS-RC),and Zung's Self-rated Depression Scal e (SDS).Both groups were matched for sex,age and education.Results:The LA group s cored lower on the VRT than did the control group ,and the mean standard score o f the Memory and/or Freedom From Distractibility factor(MFSs)of the WAIS-RC in t he LA group was lower than that of the control group.There were no significant d ifferences o f the Full Scale IQ of the WAIS-RC and the score of the SDS between the two grou ps. Conclusion:LA may contribute to cogniti ve impairment in the neurologically healthy elderly,especially involving deficits of visuospatial ability ,disfunct ion of memory and attention,as well as slowing of mental processing.

Objective:To explore the clinical effect of prostatil combined with diosmin on the elderly patients with chronic prostatitis (CP) and the macrophage inflammatory protein-2 (MIP-2) and macrophage inflammatory protein-lα (MIP-lα) in prostate fluid and serum.Methods:126 cases of elderly patients with CP in our hospital fiom January 2015 to September 2016 were selected and randomly divided into two groups.Prostatil combined with diosmin were provided to the patients in observation groups (63 cases) while the control group (63 cases) was treated by prostatil alone.The clinical effect,MIP-2,MIP-1α levels in the prostate fluid and serum before and after therapy as well as the incidence of adverse reactions were observed and compared between two groups.Results:At 12 weeks after treatment,the total effective rate of observation group was 93.7%,which was obviously higher than that of the control group (81.0%,P<0.05).The MIP-2 and MIP-1α levels in prostate fluid and serum of both groups at 12 weeks after therapy were significantly lower than those before therapy (P<0.01),which were significantly lower in the observation group than those of the control group at the same time (P<0.01).There was no significant difference in the incidence of adverse reactions between the two groups (P>0.05).Conclusion:Prostatil combined with diosmin could more safely and effectively improve the clinical efficacy in the treatment of elderly patients with CP/CPPS,which might be related to reduce the levels ofMIP-2,MIP-lα in serum and prostatic fluid.

Objective To investigate the morphological changes, apoptosis and brain-derived neurotrophic factor mRNA(BDNF mRNA)expression in rat conus medullaris induced by cauda equine compression, and to discuss the possible mechanisms. Methods Ninety male SD rats were divided into 3 groups: normal control, sham operation,and cauda equine compressed. The animals were sacrificed and took samples in 30 min, 2 hours,4 hours,8 hours,1 day,3 days,1 week,2 weeks,3 weeks after cauda equine compression model were created. The morphological study concerned with cauda equina and conus medullaris was done under light microscope and transmission electron microscope. TUNEL staining and in situ hybridization staining were used to investigate apoptosis and BDNF mRNA expression changes. The positive cells in 1mm2 were calculated,and the data were disposed through one way analysis of variance. Results Histological observation showed notable alteration of cauda equina and neurons in conus medullaris. The positive cells of TUNEL and BDNF mRNA in situ hybridization staining increased in 8 hours and 4 hours after cauda equina compressed,and both reached the climax in 3days after cauda equina compressed. At the time 3weeks after cauda equine compressed, the positive cells were still much higher than that of the control groups. Conclusion The compression of cauda equina will result in neurons morphological changes and apoptosis in medullary cone,and cause central neuron un-reversible injury. It might be one of the reasons why the prognosis is poor in cauda equina syndrome. Neurons and glial cells may produce BDNF by themselves to survival from cauda equina compression.

OBJECTIVETo explore the effect of matrine on cyclooxygenase-2 (COX-2) expression in colon cancer HT-29 cell line at the level of gene and protein.
METHODSLevels of mRNA and protein expression of COX-2, and its synthesized product prostaglandin E2 (PGE2) of colon cancer HT-29 cell line were detected by RT-PCR, Western-blot, ELISA respectively before and after treatment of matrine in different concentrations.
RESULTSMatrine had inhibitory effect on the mRNA and protein expression of COX-2, and synthesis of PGE2 in colon cancer HT-29 cell line, but had no effect on COX-1. When HT-29 cell line was treated with 2.0 mg/ml of matrine, the inhibitory rate on COX-2 mRNA expression were 100% at 6 hrs and 9 hrs after treatment; the inhibitory rate on PGE2 synthesis was 63.8 % at 9 hrs after treatment; and that on COX-2 protein expression was 48% and 100% 12 hrs and 24 hrs after treatment, respectively.
CONCLUSIONMatrine has selective inhibitory effect on gene transcription, protein expression and functional activity of COX-2 in HT-29 cell line, which is time-dependent and concentration-dependent within certain range of concentration and acting time.

AIM: To construct eukaryotic expression vector of small interfering RNA(siRNA) specific to bcl-2 and investigate the effect of recombinant plasmid on suppressing bladder cancer cell growth.METHODS: siRNA of bcl-2 gene was designed according to the principle of RNAi-based medicine, and was converted into cDNA coding expression of small hairpin RNAs(shRNA) of siRNA. The cDNA was synthesized and inserted into plasmid pGenesil-1. The recombinant eukaryotic expression vectors of pGenesil-1545 and pGenesil-1555 were controlled by the U6 promoter of RNA polymerase Ⅲ, identified by the restriction map and the sequence analysis, and transfected into T24 cells. After T24 cells were transfected for 72 h, expression of bcl-2 mRNA was assayed by RT-PCR; and MTT was used to observe the proliferation of T24 cells.RESULTS: The recombinant plasmids of pGenesil-1545 and pGenesil-1555 were identified by the restriction map and the sequence analysis. The sequences completely coincided with the designs. The expression of the bcl-2 mRNA in T24 cells transfected with recombinant plasmid decreased nearly 80%, and the growth of T24 cells was suppressed significantly.CONCLUSION: The siRNA eukaryotic expression vector against bcl-2 gene is successfully constructed. It effectively downregulates the expression of bcl-2 in T24 cells and suppresses the cell growth.
