Objective To study warfarin and aspirin for ischemic stroke prevention in elderly patients with atrial fibrillation.Methods Fifty-three elderly patients with atrial fibrillation from January 2007 to December 2009 were enrolled in this study.All patients were divided into two groups by random digits table method:warfarin group treated with warfarin and aspirin group treated with aspirin.Incidence rate of ischemic stroke,side effect and cost-effectiveness were compared between two groups.Results Forty-nine patients were followed up,the dropout rate was 7.5％(4/53),28 patients in warfarin group,21 patients in aspirin group.Incidence rate of ischemic stroke in warfarin and aspirin group was 3.6％(1/28) and 28.6％(6/21),and there was significant difference (x2 =4.28,P ＜0.05).No significant difference was observed for side effect between two groups (x2 =0.07,P ＞ 0.05).For cost-effectiveness analysis,the ratio of cost-effectiveness was 16.3 yuan and 10.4 yuan in warfarin and aspirin group respectively,and there was significant difference (P ＜ 0.05).Conclusion Warfarin is more effective for ischemic stroke prevention in elderly patients with atrial fibrillation,but costs more than aspirin.

BACKGROUND:Laryngeal cartilage defect has a higher incidence, mainly presenting with pain, sweling, and dysfunction after onset. Currently, surgical treatment is the most used in clinical treatment of laryngeal cartilage defect. Although conventional materials can effectively improve symptoms, there is a poor long-term efficacy. In recent years, there are many clinical studies on cartilage tissue engineering, but less about the actual use in the otorhinolaryngology department.
OBJECTIVE:To investigate the effect of polyhydroxyalkanoate polymer carrying chondrocytes on the repair of alogeneic laryngeal cartilage defects.
METHODS:Poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) (PHBHH) served as the extracelular matrix. Tissue engineering technology was used to prepare cel-material composite. Primary tissue-engineered cartilage tissue was transplanted directly into rabbit thyroid cartilage defect (experimental group A), or implanted into a more mature tissue-engineered cartilage for the repair of thyroid cartilage defect (experimental group B). In the experiment, PHBHH group and simple chondrocyte group were set as controls. Repairing effects on thyroid cartilage defect were evaluated through gross and histological observation.
RESULTS AND CONCLUSION:Chondrocytes in the primary tissue-engineered cartilage tissues were beaded under scanning electron microscope, and after 4 weeks of culture, a large amount of jely-shaped substrates were visible. Findings from electron microscope observation showed that the cels were distributed on the surface of composite material and cavernous voids, displaying a plurality of smal round projections. Surgical treatment was successful in al the rabbits, and there was no dyspnea and eating difficulties after surgery. One rabbit appeared to have brief wheezing in the experimental group A, two rabbits died of diarrhea in the experimental B group at 2 weeks after surgery. PHBHH composite carrying chondrocytes had certain hardness. At 4 weeks after subcutaneous implantation, mature cels were shaped as white sheets, and the material had elasticity. After 4 and 8 weeks, the space between repair zone and original cartilage tissue was smooth and plain, but the repair zone was colored yelow. In the simple PHBHH and chondrocyte groups, the repair zones were both depressed, only the connective tissues could be seen. Rabbits in the two experimental groups showed less adverse reactions compared with the two control groups (P < 0.05). These findings indicate that PHBHH composite carrying chondrocytes has better effects to repair alogeneic laryngeal cartilage defects.

Blood pressure control rate was 80.82%.Conclusions Community nursing intervention can improve patients' medication compliance and effectively control the blood pressure of the patients.

Objective To analysis the levels of serum homocysteine (Hcy)and erythropoietin (EPO)levels in patients with ischemic stroke and their relationship with carotid atherosclerosis.Methods The patients with ischemic stroke admitted be-tween January 1,2013 and July 31,2016 were selected as the subjects.Sera test of Hcy,EPO level,and then through the Doppler probe carotid artery method to check the degree of carotid atherosclerosis in all patients,and the use of quantitative records,according to set diagnostic criteria for classification,the use of grading results with the same type of Hcy,EPO lev-els of data analysis to determine the relationship between the two.Results Doppler exploration in 142 patients showed nor-mal carotid intima-media thickness in 34 patients,carotid intima-media thickening in 56 patients,and carotid plaques in 52 pa-tients.After analysis of variance (F=59.64,78.29,P<0.05),and the difference between the two groups was statistically significant (P<0.05),and the difference between the two groups was statistically significant.The data between any two groups were also statistically significant differences.108 patients with different levels of carotid atherosclerosis were graded into 47 of grade 1,34 of grade 2,and 27 of grade 3,with the same type in the plasma of different grades (F=78.39,48.61, P<0.05).After the qtest,there were no significant differences in the levels of Hcy and EPO.Data were also statistically dif-ferent between groups.Conclusion Serum homocysteine (Hcy)and erythropoietin (EPO)were associated with ischemic stroke and were associated with carotid atherosclerosis.

OBJECTIVE To investigate the effect of microRNA-129(miR-129)expression on malignant phenotypes of esophageal squamous cell cancer(ESCC) cells and its possible molecular mechanisms. METHODS The constructed miR-129-overexpressed vector (pGCMV/EGFP/miR-129) and negative control vector (pGCMV/EGFP/miR-NC) were stably transfected into ESCC cell lines (Eca109 and EC9706),respectively. Quantitative real-time PCR(qRT-PCR)was performed to detect the expression of miR-129. MTT and flow cytometry(FCM)assays were performed to analyze the effects of miR-129 on proliferation, cell cycle and apoptosis of ESCC cells. Furthermore,a luciferase reporter vector with the putative B-cell lymphoma-2(Bcl-2)3′-untranslated region(pLUC/Bcl-2-3′-UTR-wt and pLUC/Bcl-2-3′-UTR-mut)was constructed to explore whether Bcl-2 was a direct target gene of miR-129 by detecting luciferase activity. Next,Western blotting was performed to detect the expression of Bcl-2, cleaved caspase 3 and total caspase 3 proteins. RESULTS Overexpression of miR-129 significantly inhibited proliferation(P<0.01),induced cell arrest in G0/G1 phase(P<0.05)and enhanced apoptosis (P<0.05)in ESCC cells. Luciferase reporter assay indicated that Bcl-2 was identified as a direct target gene of miR-129. Results of Western blotting showed that overexpression of miR-129 significantly reduced the expression of Bcl-2 protein and increased the expression of cleaved caspase 3 protein,but induced no changes in total caspase 3 protein in ESCC cells. CONCLUSION miR-129 functions as a tumor suppressor in ESCC cells by targeting Bcl-2 gene. Therefore,miR-129 will be a potential molecular target for the treatment of human ESCC.

Objective To study the relationship between serum MMP-9,Gal-3,TGF-β1 and lung function in children with bronchial asthma.Methods The serum levels of matrix metalloproteinase-9 (MMP-9),serum galectin-3 (MMP-9),serum metalloproteinase-3 (MMP 9) and serum albumin were measured in 218 pediatric children between March 1,2012 and August 31,2016 in Shenzhen Longhua New District People's Hospital pediatric outpatient clinic.FEV1％,FEV1/FVC and FEF50 were measured and compared respectively with the index data of the control group.The lung function of the children was significantly higher than that of the control group (P＜0.05).Mild group and severe group children above.Results Serum levels measured in 218 children (F=35.34,46.51,56.73,all P＜0.05).The data of any two groups also showed statistical difference after q test,and the difference was statistically significant (FEV1 ％),1-second forced expiratory volume/forced vital capacity percentage (FEV1/FVC),forced expiratory 50％ (FEF50) of the first-second forced expiratory volume/forced expiratory volume of 1 second (F=78.13,52.69,26.24,all P＜0.05).After the q test,the data of any two groups were analyzed by ANOVA.Between the data were also statistically significant differences.Conclusion MM-9,Gal-3 and TGFβ1 in bronchoalveolar lavage and the degree of pulmonary function decline have close ties.
