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.

ObjectiveTo evaluate the efficacy and safety of tirofiban in treatment of ST segment elevation acute myocardial infarction(STEAMI) no-reflow and acute thrombosis after emergency percutaneous coronary intervention(PCI). MethodsForty patients which were made definite diagnosis of STEAMI were intra-coronary artary injection fortirofiban after emergency PCI stenting occured no-reflow and acute thrombosis. First,the dose of 0.4μg·kg-1·min-1 was given from intra--coronary artary injection of tirofiban within three minutes, after 30min the dose were given 0.1μg·kg-1·min-1 for 48 hours. ResultsThe no re-flow and acute thrombosis was completely disappeared within five minutes,at the time,side effect with in one week was not observed. ConclusionsTirofiban treatment by direct injection in coronary arteries combined with emergency PCI, can increase the repeffusion rate of infarction related vessel in AMI patients,and improve TIMI reflow. This reperfusion method was effective and safe.

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.

Objective:To compare the differences between Chinese and Korean residential elderly depression status,life satisfaction and relatedfactors in Xiamen China and Daejeon Korea.Methods:A survey was conducted on 201 elder people (≥60 years old) in Xiamen,China and 206 elder ones in Daejeon,Korea.The Geriatric Depression Scale,Life Satisfaction Index-A Scale and self-designed demographic questions were used.Data were analyzed with t-test and multiple stepwise regression analysis.Results:The LSI-A scores were higher in Korean elderly than in Chinese elderly (P ＜0.05).In Chinese elderly,social activities (β =0.37),living status (β =-0.30) and education level (β =0.16) were associated with GDS scores,and social activity (β =-0.36) and living status (β=0.17) were associated with LSI-A scores.In Korea elderly,health status (β =-0.33),social activity (β =0.24)and living status (β =-0.13) were associated with GDS scores,and health status (β =0.32),social activity (β =-0.15) and living status (β =0.16) were associated with LSI-A scores.Conclusion:It indicates that Korea elderly have better life satisfaction than Chinese elderly.

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.

Methods A total of 98 patients with recurrent or metastatic breast cancer were investigated using Chinese version of Mishel′s uncertainty in illness scale ( MUIS ) and medical coping mode questionnaire ( MCMQ ) . Results The average score of illness uncertainty in patients with recurrent or metastatic breast cancer was (62.50 ±10.89), and the level of illness uncertainty was intermediate .The score of coping style in patients with recurrent or metastatic breast cancer were higher than domestic norm .The scores of avoidance in coping style between two groups was significantly different (P<0.01).Partial correlation analysis indicated that the total score of illness uncertainty was negatively correlated with avoidance in coping style (P<0.05), positively correlated with resignation in coping style (P<0.01) and not correlated with confrontation in coping style (P>0.05).Conclusions Coping style of patients with recurrent or metastatic breast cancer is correlated with their illness uncertainty .Nurses should evaluate illness uncertainty in patients with recurrent or metastatic breast cancer and help them to take effective coping style so as to decrease illness uncertainty and improve therapeutic adherence and confidence in these patients .

Objective:To explore the effect of mobile health (mHealth) management system on dietary behavior of patients with coronary heart disease (CHD) .Methods:Using the convenient sampling method, CHD patients who were hospitalized in Department of Cardiology of Beijing Anzhen Hospital and Beijing Chaoyang Hospital of Capital Medical University were selected as the research objects from June 2019 to January 2020. The research objects were randomly divided into the intervention group and the control group using SAS software. Finally, 68 cases in the intervention group and 66 cases in the control group completed the study. The intervention group received mhealth management, while the control group received routine management, and they were followed up to 1 month after discharge. The proportion of patients with the low-salt and low-oil diet, the intake of salt, oil, staple food, vegetables, fruits, fish, shrimp, poultry and eggs, BMI and blood pressure were compared between the two groups.Results:At 1 month follow-up, the intervention group was better than the control group in terms of low salt and low oil diet, salt intake, oil intake and vegetable intake compliance, and the differences were statistically significant ( P<0.05) . At 1 month follow-up, there were no statistically significant differences in BMI and blood pressure between two groups ( P>0.05) . Conclusions:The mobile health system can effectively increase the proportion of patients with a low-salt and low-oil diet, and improve the intake compliance of salt, edible oil and vegetables in patients with CHD. In future studies, the intervention time should be extended to further explore the long-term intervention effect of mobile health and give full play to the role of mobile health in continuous behavior management of patients with CHD after discharge.
