Objective:To investigate the application value of thromboelastography (TEG) in choosing antiplatelet drug for patients with cerebral arterial thrombosis.Methods: 100 new patients with cerebral arterial thrombosis, who received single antiplatelet therapy after received dual antiplatelet therapy (aspirin and clopidogrel) in acute stage (14d), were randomly divided into observation group (50cases)and control group (50cases). According to different method of choosing drug, patients of control group randomly were implemented different single antiplatelet drug, while patients of observation group received more sensitive antiplatelet drug based on TEG results. The follow-up observation about recurrent situation of cerebral arterial thrombosis for the two groups were carried out in further study.Results: In one year, the recurrence rate of cerebral arterial thrombosis of observation group (6%, 3/50) was significantly lower than that of control group (20%, 10/50) (x2=4.332,P<0.05). The differences of recurrence rate between different antiplatelet drug in intra-group were not statistically significant.Conclusion: TEG can efficiently evaluate the therapeutic effect of antiplatelet drug, and guide the selection for drug so as to reduce the recurrence rate of cerebral arterial thrombosis.

OBJECTIVE:To explore the effects of umbilical therapy by Rheum plamatum combined with early colonic irriga-tion on the quality of life in elderly patients with colon stoma. METHODS:80 patients underwent radical resection of abdominoperi-neal rectal carcinoma were randomly divided into control group and observation,with 40 cases in each group. Control group was given early colonic irrigation;observation group was additionally given umbilical therapy by R. plamatum. Treatment course of 2 groups lasted for one month,and both were followed up for 6 months after treatment. The quality by life in 2 groups was evaluated by using QLQ-C30,and therapy costs were calculated before and after treatment. RESULTS:Compared with before treatment, function score and total health score of 2 groups improved significantly in 1,3,6 months after treatment,while symptom score and single item score decreased significantly,with statistical significance(P<0.05). In 1,3,6 months after treatment,role func-tion,social function,cognitive function,emotional function and total health score of observation group were significantly higher than those of control group,and insomnia and pain score were significantly lower than control group,with statistical significance (P<0.05). 3 and 6 months after treatment,diarrhea and economic difficulty score of observation group were significantly lower than those of control group,with statistical significance(P<0.05). 1 months after treatment,loss of appetite score of observation group were significantly lower than those of control group,with statistical significance (P<0.05). 6 months after treatment, fa-tigue,nausea and vomiting score of observation group were significantly lower than those of control group,with statistical signifi-cance (P<0.05). 6 months after treatment,nursing cost,drug cost and total cost of observation group were significantly lower than those of control group,with statistical significance(P<0.05). CONCLUSIONS:The umbilical therapy by R. plamatum com-bined with early colonic irrigation can improve the quality of life in elderly patients with colon stoma significantly and reduce treat-ment cost.

AIM: To investigate the effect of nucleolin on diabetic cardiomyopathy in mice.METHODS: A type II diabetic cardiomyopathy mouse model was prepared using a cardiac-specific nucleolin-overexpressing transgenic mice.The mice were divided into wild-type mouse control group, nucleolin transgenic mouse control group, wild-type mouse diabetes group and nucleolin transgenic mouse diabetes group.Wheat germ agglutinin (WGA) fluorescent dye, Masson staining and PowerLab system detection were used to further clarify the role of nucleolin on cardiac hypertrophy, fibrosis and cardiac function in type II diabetic cardiomyopathy mice.RESULTS: Compared with wild-type mouse control group, no significant increase in blood glucose level was found, while genetical myocardial cell hypertrophy was significantly attenuated in nucleolin transgenic mouse diabetes group.The collagen fibers were also significantly reduced, and hemodynamic indexes ± dp/dtmax, left ventricular end-diastolic pressure, left ventricular systolic pressure and heart rate were also improved.The above differences were statistically significant.CONCLUSION: Nucleolin may reduce the occurrence of myocardial hypertrophy and fibrosis, thus improving the cardiac function of diabetic cardiomyopathy mice.
