Objective To evaluate the curative effect of urokinase combined with low molecular heparin sodium in managing arteriovenous fistula embolism. Methods Toally 48 patients with arteriovenous fistula embolism treated from January 2014 to October 2015 were selected for the study, where 22 were assigned into control group and 26 as trial group according to the registration time. The former group were treated with urokinase and the latter with urokinase combined with low molecular heparin sodium. The rate of recanalization, the rate of thrombosis recurrence, and the adverse reactions were compared between the two groups. Results The recanalization rate in the trial group was higher than that in the control group (P<0.05). The rate of thrombosis recurrence in the trial group was significantly lower than that the control group. There was no statistical difference in adverse reactions between the groups. Conclusion The thrombolytic effect of urokinase combined with low molecular heparin sodium is superior to that of urokinase alone, with a higher rate of recanalization.

Objective To explore the correlation of the indoor carbon monoxide concentration and chronic diseases by monitoring the indoor carbon monoxide concentration timely.Methods Collected the data of non-traumatic patients(n=80)from July 201 1 to January 2014,and assigned them into the experiment group with carbon monoxide concentration measured and the control group without measured.All the subjects were further divided into one group with complaint of carbon monoxide poisoning and the other one without.For patients exposed to high concentration of carbon monoxide,carboxyhemoglobin was also measured and APACHEⅡ was scaled,and the relationship between them was analyzed.The confirmation and misdiagnosis rate of carbon monoxide poison-ing were calculated.For the patients with acute exacerbation of chronic diseases like chronic cardiac failure,chronic obstructive pul-monary disease,cerebral infarction induced by carbon monoxide poisoning,BNP,CAT and NIHSS were documented on admission and during follow-up with removal of carbon monoxide exposure and compared respectively.Results The relationship between blood carboxyhemoglobin,APACHEⅡ scores on admission and indoor carbon monoxide concentration was linear,and obviously positive.Between the experiment group(n=40)and the control group(n=40),there was significant difference(P <0.05)in confirma-tion rate and misdiagnosis rate with 80.00% vs.55.00% and 6.25% vs.81.80% respectively.For the 54 patients with carbon monoxide poisoning diagnosed,the changes between before and after removal of carbon monoxide exposure of the CAT scores of chronic obstructive pulmonary disease and NIHSS score of CI disease and myoglobin,troponin I,creatine kinase isoenzyme,BNP for chronic cardiac failure were significantly different(P <0.01).Conclusion The indoor carbon monoxide concentration may indicate the severity of carbon monoxide poi-soning,which could increase the confirmation rate of carbon monoxide poisoning,and reduce the misdiagnosis rate.It is helpful to identify carbon monoxide exposure,the common inducing factor,so as to improve the patients′clinical symptoms.

Objective To observe the distributions of epidermal growth factor receptor(EGFR),transforming growth factor ?(TGF ? 1,? 2,? 3)and thyroid transcription factor 1(TTF 1)in developing lungs,and to discuss their functions and relationships each other. Methods The expression of EGFR and TGF ? was examined in mouse fetal lungs by immunohistochemistry.TIGER image analysiser was used in TTF 1 quantitative study. Results 1.In the early developmental phase,EGFR localized in the epithelium of airway surface,TTF 1 was expressed predominantly in the nuclei of distal lung buds and TGF ? was expressed in the bronchioles with localization patterns.2.At the late developmental phase,the positive reactions of EGFR and TTF 1 were mainly detected in alveolar cells.TGF ? expressed in mesenchymal at high levels.3 The average optical density(A A )of TTF 1 in the distal epithelial cells increased gradually during the development,while their volume(VOL)and volume integrated optical density(VI A )all decreased.Conclusion\ The functions of EGFR,TGF ? and TTF 1 might be respectively different at different developmental stages.They not only stimulate the process of branching morphogenesis,but also modulate epithelial maturation and differentiation.\;[
