Conclusion Mosapride citrate in reflux esophagitis treatment and intervention effect analysis found that the compared with conventional therapy, can be in At the same time, it can improve the curative effect of the patients, and will not increase the possibility of adverse reactions, so it is worthy of clinical reference.

Background Leber hereditary optic neuropathy (LHON) is a maternally inherited disorder characterized by a bilateral acute or subacute painless central visual loss in young adults,predominately in males.So far no one theory can completely explain all clinical manifestations of LHON.Objective This study was to investigate whether there is a linkage between X-chromosomal and mitochondrial mutation in the inheritance of a Chinese LHON pedigree with only male patients.Methods This study was approved by Ethic Committee of Affiliated First Hospital of Zhengzhou University and followed by Declaration of Helsinki.A Chinese LHON pedigree was included in Anyang city from January 2008 to August 2016.Periphery blood of 5-10 ml was collected from 4 sufferers,13 maternal members and 10 non-maternal members for DNA extraction and PCR sequencing.The gene scanning and genotyping analysis were performed by ABI-PRISM 3100 genetic analyzer and Genotyper 3.7 software,and linkage analysis was carried out with Linkage software for the calculation of logarithm of odds (LOD).Mitochondrial DNA (mtDNA) sequence,fluorescence-based Genescan for X-chromosomal sequence were analyzed in the propositus and haplotype was evaluated.Results A total of 5 generations and 71 families were included in the pedigree,with 6 male sufferers,30 maternal members and 41 non-maternal members.The visual acuity was ≤0.10,and the central visual field defection,the optic nerve flushing was found in the acute phase,different levels of the optic nerve fibers atrophy were found in the chronic phase;visual evoked potential (VEP) amplitude was low and peak latency were found in the male patients,and no any ocular abnormality was seen in the maternal members,meeting a maternally inherited characteristics,with the penetranee of 20％.The three primnary mutations were not been found in this family bv PCR sequencing,mtDNA sequencing appeared 31 variation of loci in the proband,including a known G3635A mutation,as well as an unknown ND5 A12340G missense mutation and ND4 T11809C synonymous mutation as well as 28 polymorphism of locus,and the proband was mitochondrial haplotype F1.The maternal families were mutation carriers of G3635A and AI2340G loci,while the same mutation was not found in the normal family members and 107 controls.The maximum two point parametric LOD score was 1.46(θ=0.0) for marker DXS1060,1oeated at Xp22.3,and the two-point and multipoint non-parametric linkage analysis were significant (all at P＞0.05).Conclusions The ND5 A12340G and ND1 G3635A mutations coexist in this LHON family,and the ND5 A12340G mutation is a newly reported mutation.There is no evidence for an X-linked modifiers loci in this Chinese LHON family.

Objective To study the short term and long term response and the safety of the different doses of recombinant interferon alfa 1b(IFN? 1b) for the treatment of the patients with chronic hepatitis B and the predictive factors of the response. Methods 146 Chinese patients with chronic hepatitis B entered randomly into four groups. Three groups were given with IFN ? 1b 3 million unit (MU), 5 MU and 10 MU respectively. The control group was given placebo. The short term(ETR) and long term(SR 12) responses and side effect were observed. Selected nineteen items (host related, drugs related and virus related), which affected the response of IFN alfa 1b probably (host, virus and drugs, et al) were analyzed. Results The end treatment response (ETR) of the IFN ? 1b 5 MU therapy was 55.3%, and 10 MU was 58.1%. Both efficacy were higher than the group of 3 MU IFN alfa 1b (32.6%) and control therapy group (5.9%, P

Objective To study the relationship between the mutation of androgen receptor(AR) gene and the development of human prostat e cancer. Methods All exons of AR gene except trineucl eic acid repeat polymorphism were amplified by PCR and selected by single strand conformation polymorphism( SSCP) in 27 paraffin-embedded slides of human pros tate cancer. The abnormal mobility shifts were further detected by direct DNA c ycle sequencing. Results Three abnormal mobility shifts respectively in exon A.D.G were found by SSCP in three prostate cance r tissues. One point mutation was found in 296 amino acid (C 966→A,Ser29 6Arg) from exon A.This point mutation has not been reported before. Conclusions This mutation might change the transcriptive activity of AR, and it might be correlated to PCa progression.

This paper deals with the analysis and discussion on how to harmonize the following three relations respectively between general objective and concrete objective, pertinence and systematicness as well as political nature and actualization in ideological and political theory education and teaching in higher institutions.

OBJECTIVETo establish a model of hypoxic postconditioning of dermal microvascular endothelial cells.

METHODSDuring reoxygenation after hypoxia, cells received three times of hypoxic/ reoxygenation alternate treatment for a certain time. The cells were seeded on 6-well plates, with one plate for one group. They were divided into 6 groups as group 1 ( Control), group 2 (8h hypoxia + 24h reoxygenation), group 3 (8h hypoxia + 2 min x 3 times post-hypoxia treatment) , group 4 (8h hypoxia + 5 min x 3 times post-hypoxia treatment), group 5 (8h hypoxia + 10 min x 3 times post-hypoxia treatment), 6 group (8h hypoxia + 20 min x 3 times post-hypoxia treatment). Each group underwent 8 h hypoxia + 24 h hypoxia Buffer and reoxygenation. Lactate dehydrogenase (LDH) was detected during the process. Apoptosis rate was calculated by staining Tunel method. Bcl-2, Bax and activated caspase-3 protein were detected by Western Blot.

RESULTSIn the continuous hypoxia process, the LDH was (1563 ± 83.35) IU/L at 8h and (582.85 ± 58.25 ) IU/L at 0h, showing a statistical difference (P = 0.0001). Western blotting results showed that the expression of Bax/Bcl-2 in group 2 was 0.38 ± 0.02, showing a significant difference when compared with that in group 3 (0.23 ± 0.01) and group 4 (0.22 ± 0.02) (P = 0.012, P = 0.005), while not when compared with that in group 5 (0.33 ± 0.02) and 6 groups (0.34 ± 0.01) P > 0.05). The ratio of Activated caspase-3/caspase-3 in group 2 (6.30 ± 1.50) was significantly higher than that in group 3 (2.17 ± 0.26) and group 4 (2.63 ± 0.31) (P = 0.008, P = 0.019); while not in group 5 (4.36 ± 0.29) and group 6 (4.97 ± 0.51) (P > 0.05).

CONCLUSIONSThe model of hypoxic postconditioning of human dermal microvascular endothelial cells is successfully established.

This study developed a novel approach of targeting malignant glioma with pMAGE-A1(278-286)-specific cytotoxic T lymphocytes (CTLs) induced from the peripheral blood mononuclear cells of healthy donors by multiple stimulations with human leukocyte antigen (HLA)-A2-restricted pMAGE-A1(278-286) peptide-pulsed dentritic cells. Cytotoxic assays were performed by the colorimetric CytoTox 96 assay to analyze cytotoxic activity of the induced CTLs against various target cells. The induced CTLs showed approximately 45% specific lysis against T2pMAGE-A1(278-286) (pMAGE-A1(278-286) peptide pulsed T2 cells) and U251 (HLA-A2(+), MAGE-A1(+)) at an effector:target ratio of 40:1, and approximately 5% cytolysis against T2pHIV, A172 (HLA-A2(-), MAGE-A1(+)), K562 and T2 cells without being pulsed with peptide at any effector:target ratio. The specific killing activity of the induced CTLs against T2pMAGE-A1(278-286) and U251 was much more obvious than in any other control group (P<0.05). The cytotoxic activity against the T2pMAGE-A1(278-286) and U251 was significantly eliminated by anti-HLA class I mAb W6/32. These results suggest that pMAGE-A1(278-286) epitope may serve as a surrogate tumor antigen target of specific immunotherapy for treating HLA-A2 patients with malignant glioma.
