Objective To study the differentially expressed proteins and their biological behavior in colorectal carcinoma tissues and the normal colonic mucosa by proteomics and molecular biology techniques. Methods The technique of fluorescence two dimension differential gel electrophoresis (2-D DIGE) was used to analyze the expression of differential proteins in normal colorectal mucosa and primary cancer foci. Liquid chromatography with electrospray ionization tandem mass spectrometry (LC-ESI-MS/MS) was used to identify the differential proteins. Transfection experiment of colorectal cancer cells was performed with the differential protein cDNA, and the changes in cytobiological behavior were observed. Results Significant differences of protein expression levels were found by two-dimension electrophoresis. Eight differential protein spots were analyzed and identified. Human carbonic anhydrase Ⅱ and protein disulfide isomerase were detected in normal colorectal mucosa, but not in primary cancer foci. Phosphoglycerate kinase 1, fumarate hydratase and aldolase A were expressed in primary cancer. After transfection with human carbonic anhydrase Ⅱ cDNA, the abilities of Lovo cells were obviously reduced in invasiveness, chemotaxy motor and drug resistance. Conclusions Differences on protein expression levels are found between normal colorectal mucosa and primary cancer foci by 2-DE DIGE. The pathogenesis of colorectal carcinoma is related to the reduced expressions of carbonic anhydrase II and protein disulfide isomerase and enhanced expression of aldolase A. The technique of differential proteomics is useful in reaching a indepth understanding of the pathogenesis mechanisms of human colorectal cancer.

Aim To investigate the effect of GW0742 on the endothelial dysfunction induced by high glucose
(glucose at 55 mmol · L -1 )in isolated rat thoracic aorta and its related mechanisms.Methods The end
othelium-dependent relaxation of acetylcholine was per-formed in the absence or presence of GW0742 at differ-ent concentrations under high glucose condition.The structure of aorta was observed by HE staining.Moreo-ver,the content of NO was also measured by nitrate re-duction method.The mRNA and protein expression were detected by quantitative real-time PCR and West-ern blot,respectively.Results Compared with the control group,acetylcholine-induced vasodilatation was impaired by high glucose.Meanwhile,the structures of endothelial cells and smooth muscle cells were also in-terrupted.Furthermore, the expressions of PPARβmRNA and protein reduced while the NF-κB p65 ex-pression increased significantly which occurred in par-
allel with decreasing eNOS expression and NO concen-tration (P <0.01 ).GW0742 (0.01 ,0.1 ,1 μmol· L -1 )restored the relaxation of acetylcholine in a dose-dependent manner,and reversed the mRNA and pro-tein expression of PPARβ,NF-κB p65 and eNOS,as well as NO content (P <0.01 ).Conclusion GW0742 attenuates the injury of endothelial dysfunc-tion induced by high glucose,which may be,at least partly,mediated by the up-regulation of PPARβ,then the down-regulation of NF-κB,and the activation of eNOS-NO signal pathway.

ObjectiveTo determine the possible causes for functional delayed gastric emptying (FDGE) and its diagnosis and treatment. MethodsThe clinical data of 53 FDGE patients after subtotal gastrectomy from 1987 to 2001 were retrospectively analysed. ResultsAll the 53 patients were recovered and discharged. Among them, 11 were misdiagnosised as mechanical ileus and were reoperated on. ConclusionsThe main cause of FDGE may be the disturbance of gastrointestinal motility which may be caused by vegetative nerve injury during the operation. The main therapy is non-surgical treatment and reoperation should be avoided at the early stage.

Objective To investigate the effect of NaAsO2 on the binding levels of methyl CpG binding protein 2(MeCP2),DNA methyltransferase 1 (DNMT1) and histone deacetylase 1(HDAC1) to the hypermethylation promoter region of MGMT gene in HaCaT cells,in order to provide a basis to deepen the interpretation of the role of arsenic poisoning mechanism.Methods HaCaT cells were treated repeatedly and interval with different concentrations of NaAsO2(3.13,6.25,12.50,25.00 μnol/L,respectively) for 72 h.Untreated HaCaT was used as blank control group and human epidermal squamous carcinoma cell line(A431 cells) as positive control group.The binding levels to the two transcription regulatory regions(ChIP1,ChIP2) and to the coding region(ChIP3) of MGMT 8ene were detected by chromatin immuno-precipitation combined with quantitative PCR.Results The differences of binding levels of MeCP2,DNMT1 and HDAC1 to ChIP1 and ChIP2 in each group were significant (F=7.387,84.634,78.442 and 19.263,69.649,26.546,all P ＜ 0.05).The binding levels of MeCP2,DNMT1 and HDAC1 to ChIP1 and ChIP2 in each NaAsO2 exposed group[3.13 μmol/L NaAsO2 exposed group:(136.00 ±16.97)％,(145.00 ± 2.83)％,(88.50 ± 19.09)％ and (106.50 ± 37.48)％,(112.34 ± 8.73)％,(59.71 ± 8.49)％;6.25 μmol/L NaAsO2 exposed group:(130.00 ± 42.43)％,(154.50 ± 4.95)％,(101.00 ± 1.27)％ and (88.50 ±3.54)％,(134.32 ± 2.82)％,(102.75 ± 19.91)％ ; 12.50 μmol/L NaAsO2 exposed group:(141.50 ± 23.33)％,(161.50 ± 7.78)％,(125.00 ± 11.31)％ and (119.50 ± 24.75)％,(171.59 ± 3.54)％,(167.61 ± 10.61)％; 25.00μmol/L NaAsO2 exposed group:(134.50 ± 43.13)％,(472.50+ 50.20)％,(383.50 ± 30.41)％ and (180.09 ±12.73)％,(348.50 ± 27.58)％,(158.45 ± 12.02)％] were higher than that in the blank control group[(51.50 ±9.19)％,(82.00 ± 12.73)％,(25.03 ± 2.91)％ and (37.02 ± 4.24)％,(91.56 ± 26.16)％,(19.09 ± 2.90)％,all P ＜ 0.05].The differences of binding levels of MeCP2 to ChIP3 in each group were not significant(F =1.670,P ＞0.05),but the differences of binding levels of DNMT1 and HDAC1 to ChIP3 were significant (F =4.404,9.863,all P ＜ 0.05),and only the binding levels in the 25.00 μmol/L NaAsO2 exposed group [(615.85 ± 29.63)％,(306.09 ± 59.40)％] were higher than that in the blank control group[(99.70 ± 12.02)％,(92.45 ± 48.79)％,all P ＜ 0.05].Conclusions MeCP2 can bind to the methylated MGMT gene transcriptional regulatory regions which are induced by arsenic and leads to histone deacetylation by the recruitment of DNMT1 and HDAC1 and,meanwhile,DNMT1 can bind to the coding region of MGMT gene to recruit HDAC1 in a methyl DNA binding protein(MBD) independence manner and media MGMT gene silencing through the chromatin remodeling way,which might be the early molecular events of arsenic poisoning.

Objective To explore the inhibiting effects of arsenic trioxide and cisplatin on MG-63 cells. Methods Using MTT assay,flowcytometry,phase contrast microscopy and electron microscopy methods,the therapeutic effect of arsenic trioxide was studied for the osteosarcoma in the cultured MG-63 cells in vitro,and compared these effects with cisplatin. The inhibitory rotes of cell growth and the effect of apoptosis and cell cycle were compared between arsenic trioxide and cisplatin on MG-63 cells. Results The contrast phase microscope revealed the adhesion ability of normal groups was good and cellular morphology showed epithelium cells. But the celhdar morphology showed irregular arrangement in arsenic trioxide groups and cytoplasmic vacuoles in cisplatin group. Electron microscope revealed the globular plasmalemma ecphymas in cell surface of control groups,the enlarged crista mitochondriales and the double-deck membrane structure appeared clearly. But electron microscope revealed globular plasmalemma processes in cell surface of arsenic trioxide groups,thinned crista mitochondriales and clearly seen karyopycnosis and nuclear membrane of apoptotic cells. The globular plasmalemma processes in cell surface of cisplatin groups were separated,nuclear membrane thickened and chromatin were in sandy shape. Both arsenic trioxide and cisplatin inhibited effectively MG-63 cells growth. There was a significant difference in different groups of inhibition ratios to the growth of cells(all P < 0.05). In 2,4,8,16,32,64,128 hours,the inhibition ratios(%) of arsenic trioxide(56.31±0.03,70.00±0.06,79.84±0.03,87.31±0.13,84.70±0.09,90.68±0.06,91.18±0.05) and cisplatin groups(7.55±0.15,15.70±0.17,30.72±0.07,49.80±0.05,45.11± 0.13,61.62±0.08,93.80±0.12) were obviously increased as compared with those in the control group(2.03± 0.07,2.78±0.08,3.11±0.01,5.67±0.04,12.23±0.04,18.65±0.04,24.45±0.04,all P < 0.05). Moreover the inhibition ratio of arsenic trioxide group in 2 to 32 hour was significantly higher than that of cisplatin group and the effect was more faster(all P < 0.05). Both arsenic trioxide and cisplatin could induce apoptosis MG-63 cells. There was a significant difference in different groups of the inhibition ratio to the growth of cells(F = 13.317,P < 0.05). The inhibition ratios(%) of arsenic trioxide on 24,36,48 hour(20.50±3.78,45.76±9.90,25.16±15.41),and cisplatin groups on 24,36,48 hour(12.55±1.51,18.85±3.40,12.37±5.43),were obviously increased as compared with those in the control group at the same time(6.57±1.48,8.03±2.08,6.54±1.30,P< 0.05 or<0.01). Both arsenic trioxide and cisplatin inhibited MG-63 cells cycle. There was a significant difference in different groups of the inhibition ratio to the growth of cells(F = 54.579,43.429,21.795,P < 0.05 or < 0.01). And the total inhibition ratios(%) in G1 cycle of arsenic trioxide(78.26±5.24) and cisplatin groups(80.48±2.81) were obviously increased as compared with those in the control group(57.49±6.65,all P < 0.05 or < 0.01). Conclusions Arsenic trioxide and cisplatin can effectively inhibit the proliferation of MG-63 cell line and induce the apoptosis of MG-63 cell line. And the effects induced by arsenic trioxide group were faster than that of cisplatin groups. Moreover arsenic trioxide can arrest the cell cycle of MG-63 cell line at G1 phase.
