Objective:Colorectal cancer is one of the common gastrointestinal tumors.Recent studies have shown that, the expression of PDEF can promote the differentiation of Secretory progenitor cells to goblet cells in the intestinal tissue.Therefore the oc-currence of colorectal cancer may be related to expression of PDEF.In this study,we tried to investigate the effects of proliferation and invasion after interference targeting prostate-derived ETS factor in colorectal cell lines HT29.Methods: HT29 cells were transiently transfected with PDEF shRNA plasmids and blank control plasmid via cathodolyte liposome transfection method.By fluorescence microscopy,RT-PCR,Western blot technique to detect the expression of PDEF mRNA and protein in normal control group,blank control group,shRNA group.The proliferation and invasion ability of HT29 cells after transfection were assessed by MTT assay and Transwell invasion assay respectively.Results: Green fluorescent protein was observed in blank control plasmid group and shRNA plasmid group.Western blot showed the reduced PDEF protein expression compared with normal control group and blank control group.Interference PDEF gene expression can significantly promote the proliferation of HT29 cells (P<0.05).The ability of cell invasion in interference group was significantly higher than the normal control group and blank control group after 48h ( P<0.05).Conclusion:Interference PDEF in HT29 cells can promote cell proliferation and invasion.

Background 5-hydroxytryptamine 2A receptor (5-HT2A) gene has been regarded as a candidate gene for susceptibility to schizophrenia. In particular, the 5-HT2A receptor has received much attention because it demonstrates to be an important site of action of atypical antipsychotic agents to alleviate negative symptoms. The current study investigated whether the 5-hydroxytryptamine 2A receptor (5-HT2A) gene T102C polymorphism was associated with treatment response to risperidone in the first episode Chinese patients with schizophrenia.Methods 201 first episode Chinese Han patients with schizophrenia were given risperidone for up to 56 days.Genotyping of 5-HT2A gene T102C polymorphism were performed by using PCR-RFLP. The Positive and Negative Symptom Scale (PANSS) was used for the evaluation of the severity of psychotic symptoms before and after 8 weeks treatment with risperidone.Results 5-HT2A receptor 102 -T/T genotype was significantly associated with both the PANSS total and negative syndrome subscale scores before treatment, and with the reduction rates in both the PANSS total and negative syndrome subscale scores after eight weeks risperidone treatment.Conclusions The results suggest that 5-HT2A T102C A/A1 genotype subgroup influences individual response to risperidone in first-episode Chinese patients with schizophrenia.

Objective:To identify the risk factors for premature proximal femur physeal closure (PPC) in children treated surgically for femoral neck fractures.Methods:Data of 106 children with an open triradiate cartilage who were treated surgically for a femoral neck fracture were retrospectively analyzed. Age, gender, laterality, mechanism of injury, the type of fracture, initial displacement, time to reduction, fixation method, whether the implant crossed the physeal plate, reduction method, reduction quality and development of femoral head avascular necrosis (AVN) were collected. PPC of the proximal femur was assessed through postoperative 6-12 months radiographs.Results:A total of 106 patients with an open triradiate cartilage were followed up, with an average duration of 20.4±13.3 months (range, 6-86 months). The overall rate of PPC following paediatric femoral neck fractures treated surgically was 36.8% (39/106). Among the 39 patients with PPC, 25 were males and 14 were females; the average age at the time of injury was 9.7±3.6 years (range, 3-15 years); 23 patients were involved in left hips and 16 were in right; the mechanisms of injury included motor vehicle accident in 5 fractures, falling injury in 21, sports-related injury in 12 and other causes in 1 fracture; two hips were Delbet type I, and 26 hips and 11 hips were Delbet type II and III, separately; type II and III of initial displacement were involved in 26 and 13 patients, separately; the mean duration from injury to surgery was 3.3±2.8 d (range, 1-14 d); 2 hips were treated with Kirschner wires, 35 hips with screw fixation, and the remaining 2 hips underwent screw and plate fixation; 2 hips had the hardware crossing the proximal femoral growth plate, and the remaining 37 hips didn’t; 15 hips were treated by closed reduction and internal fixation, and the other 24 hips underwent open reduction and internal fixation; anatomical reduction was achieved in 14 patients, acceptable reduction in 24 hips and unacceptable reduction in 1 hip; 24 hips developed AVN at the latest follow-up and the remaining 15 hips didn’t. Statistical analysis indicated that age ( t=3.875, P< 0.001), the severity of initial displacement ( Z=-2.118, P=0.034) and the rate of AVN ( χ2=42.280, P< 0.001) in patients with PPC were significantly higher than those in patients without; Logistic regression analysis confirmed age ( OR=1.288, P=0.011) and AVN ( OR=40.336, P< 0.001) as risk factors for PPC. ROC curve analysis indicated 10 years was the cut off age to significantly increase the rate of PPC. The rate of PPC in patients aged over 10 years (63.6%, 21/33) was significantly higher than that (24.7%, 18/73) in those aged less than 10 years ( χ2=14.848, P< 0.001). Conclusion:Age over 10 years and AVN are risk factors for PPC in children with femoral neck fractures treated surgically.

In order to obtain three isoforms of apolipoprotein E (apoE), the cDNA encoding apoE3 was obtained by RT-PCR from normal human liver tissue. Site-directed mutagenesis was used to obtain the cDNAs encoding apoE2 and apoE4 isoforms. The 3 cDNAs were subcloned into vector pGEM-3Z and verified by DNA sequencing. The expression recombinant which can express the target protein as a (His) 6-tagged fusion was constructed by subcloning apoE cDNA into vector pT7-PL. The purified proteins were gained by Ni-NTA column. The SDS-PAGE results revealed the 6 His fusion proteins (apoE2, apoE3 and apoE4) were correctly expressed and purified successfully.

Objective To study the effect of combined atorvastatin and ezetimibe pretreatment on perioperative hs-CRP after elective PCI.Methods One hundred and fifty-six patients with typical chronic stable angina pectoris were randomly divided into atorvastatin treatment group (n=78) and combined atorvastatin and ezetimibe treatment group (n=78).Their serum hs-CRP,TC and LDL-C level was measured before PCI,at hours 8,24,48 and on day 7 after PCI.Results In comparision with pre-operation,the serum TC and LDL-C levels were significantly lower in two groups (P＜0.01) and in combined atorvastatin and ezetimibe treatment group than in atorvastatin treatment group on day 7 after PCI (P＜0.05).The serum hs-CRP level was significantly higher in two groups at 8 h after PCI than before PCI,reached its peak at 24 h after PCI,continued to increase at 48 h after PCI (P＜0.01),no significant difference was found between the two groups on day 7 after PCI (P＞0.05).The average serum hs-CRP level was lower in combined atorvastatin and ezetimibe treatment group than in atorvastatin treatment group at hours 8,24 and 48 after PCI (P＜0.05) with no significant change found between the two groups on day 7 after PCI (P＞0.05).Conclusion The effect of combined atorvastatin and ezetimibe pretreatment is better than that of atorvastatin alone on perioperative acute inflammatory reactions after PCI.

Objective:To determine the correlations of single nucleotide polymorphisms (SNPs) with atrial fibrillation (AF) in the Chinese Han population from the central plains.Methods:A total of 168 hospitalized patients,including 56 AF and 112 controls,were recruited in this case-control study.The clinical data were obtained from the medical records.All 5 SNPs,rs337711 in KCNN2,rs11264280 near KCNN3,rs17042171 near PITX2,rs6771157 and rs6795970 in SCN10A,were genotyped using amplification refractory mutation system-polymerase chain reaction or direct sequencing.The x2 test was used to compare categorical variables and preliminarily examine correlations between the genotype frequencies and AF.Subsequently,a logistic regression model was constructed to determine the associations between the SNPs and AF based on the above screened results.Odds ratios (ORs) and 95％ confidence interval (CI) were calculated to assess the strength of the correlations.Moreover,we downloaded the genotype data from the HapMap Project for linkage disequilibrium analysis ofrs17042171.Results:AF patients were likely to be of older age and longer left atrial diameter and had more coronary artery disease and higher hypertension compared with the control group (P＜0.05).Among the 5 SNPs,the frequency distribution of genotype AA for rs17042171 was significantly different between the AF and control groups (P＜0.05).After adjusting for several covariates,there was still a high risk ratio in patients with the AA genotype compared with the AC+CC genotype (OR:5.591,95％CI 2.176 to 14.365,P-B＜0.008).Similarly,stratification analysis on the AA genotype demonstrated significant differences between rs17042171 and persistent AF.However,there were not significant correlations between AF and the control groups for the other 4 SNPs (P＜0.05).Conclusion:Rs17042171,near PITX2 on chromosome 4q25,is associated with AF susceptibility in the Chinese Han population from the central plains,suggesting that this SNP can provide a new strategy for clinical diagnosis in AF patients.

ObjectiveTo explore the metabolic changes during the development of Tupaia belangeri breast tumors, to investigate the close relationship between the changes of serum metabolic substances and the occurrence and progression of tumors, and to screen for biomarkers reflecting the progression of breast tumors. MethodsBreast tumors in Tupaia belangeri were induced by orally administering 7,12-dimethylbenzoanthracene (DMBA) three times, with a 15-day interval between each administration, along with a high-fat and high-sugar diet. The DMBA-induced breast cancer group and the DMBA-inducedwithout breast cancer group were compared with the control group. Untargeted determination of serum metabolites was performed using gas chromatography-time-of-flight mass spectrometry (GC-TOFMS) in DMBA-induced Tupaia belangeri with breast cancer, DMBA-induced without breast cancer and the control group. Multidimensional statistical analysis including unsupervised principal component analysis (PCA), and orthogonal partial least squares analysis (OPLS-DA) were conducted. Furthermore, t-test was used for intergroup differential comparison. Differential metabolites were screened under VIP>1 and P<0.05 conditions, and significantly changing differential metabolites were identified using the HMDB online database. The Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway database was utilized to enrich metabolic-related gene regulatory pathways. ResultsThe incidence of breast tumors was 40% in DMBA-induced Tupaia belangeri. Compared with the control group, 30 metabolic differential products were detected in the serum of the group with breast cancer, with 18 down-regulated and 12 up-regulated (VIP>1, P<0.05). KEGG pathway analysis revealed significant changes in four metabolic pathways: glutamate metabolism, glyceride metabolism, citric acid cycle, and alanine metabolism. Compared with the group without breast cancer, 18 metabolic differential products were detected, with 7 down-regulated and 11 up-regulated (VIP>1, P<0.05). KEGG pathway analysis revealed significant changes in the citric acid cycle and glutamate metabolism. Compared with the control group, 31 metabolic differential products were detected in the serum of the groups without breast cancer, with 14 down-regulated and 17 up-regulated (VIP>1, P<0.05). KEGG pathway analysis revealed significant changes in three metabolic pathways: glutamate metabolism, glyceride metabolism, and citric acid cycle. ConclusionMetabolomics analysis can reveal the characteristics of changes in metabolites in the serum of breast tumors. The results suggest that glutamate metabolism, glyceride metabolism, citric acid cycle, and alanine metabolism pathways are associated with the occurrence and development of DMBA-induced breast tumors in Tupaia belangeri. It provides a foundation for further research into the biological mechanism of breast cancer.
