Objective To explore the clinical value of intravenous thrombolysis in the treatment of patients with acute myocardial infarction (AMI) and cardiac arrest after cardiopulmonary resuscitation.Methods 120 patients with AMI and cardiac arrest admitted in our hospital from Mar 2009 to Mar 2013 were divided into thrombolytic group (n=50) and control group (n=70) according to the voluntary principle.The recanalization rate,return time of spontaneous circulation,left ventricular ejection fraction (LVEF) and creatine kinase-MB (CK-MB),complications and hospital mortality rate were compared between two groups.Results The recanalization rate was significantly higher in thrombolytic group than in control group (76％ vs.11.4％,x2 =84.81,P＜ 0.05).Restoration of spontaneous circulation was significantly shorter and LVEF after one week of treatment and CK-MB peak were significantly higher in thrombolytic group than in the control group (t=6.796,4.342,2.923,respectively,P＜0.001 or 0.05).The incidences of heart failure,angina,arrhythmia,and re-infarction were significantly lower in thrombolytic group than in control group (x2 =6.10,20.95,8.52,11.10,respectively,all P＜0.05).There were no significant differences in the incidences of intracranial hemorrhage and upper gastrointestinal bleeding between thrombolytic group and control group (x2 =2.19,3.74,both P＞0.05).Hospital mortality rate was significantly lower in thrombolytic group than in control group (10 ％ vs.25.7 ％,x2 =4.65,P＜0.05).Conclusions Intravenous thrombolysis has a higher recanalization rate,faster recovery time of spontaneous circulation,fewer complications and higher hospital survival rate for the treatment of cardiac arrest in patients with acute myocardial infarction after cardiopulmonary resuscitation.

Objective To explore a simple, effective and rapid method for indoor air disinfection. Methods Three kinds of disinfection methods were carried out (method A: wiping surfaces of floor and walls of room with water and ultraviolet irradiation, method B: wiping surfaces of floor and walls with chloro-disinfectant and ultraviolet irradiation, method C: wiping surfaces with chloro-disinfectant and spraying chloro disinfectant containing chlorine) and the effectiveness of different disinfection methods was compared. Results The result showed that all of the three methods could decrease natural fallen bacteria count in isolated room air to up to the standard, and the disinfection effectiveness of method C was better than the method A and method B. Conclusion The result indicated that method C was an effective and simple method for indoor air disinfection.

Objective_To investigate whether overexpression of TRAF4 in human breast cancer may have impact on its cell proliferation.Methods_This study has two groups, MDA-MB-231 transfected with pcDNA3-TRAF4-DM-TRAF or pcDNA3 .We detected the expression and localization of TRAF4 with immunofluorescence and western blot.We detected the expression of the phosphorylation level of p70S6K and S6 with westernblot.Flow cytometry was used to detecte cell cycle.MTT Assay was used to detected cell reproductive capacity.Results_TRAF4 local-ized in both cytoplasm and nuclei in MDA-MB-231.Nuclear expression of TRAF4 in nuclei was lower than that in cytoplasm (P<0.05).After pcDNA3-TRAF4-DM-TRAF was transfected into the cells, the expression of TRAF4 in nuclei was increased (P<0.05).The phosphorylation level of p70S6K and S6 significantly increaseced (P<0.05,P<0.01).More S phase cells were recorded(P<0.01) by FCM.The cell proliferation was promoted by MTT ( P<0.01) .Conclusions_The expression of TRAF4 in nuclei may play an important role in the cell prolif-eratuion by promoting p70S6K and S6 activation.

Objective To investigate and evaluate the improvement of the quality of life of pulmonary infection in AIDS patients treated by Chinese traditional treatment combined Western medicines treatment.Methods Sixty cases with HIV infection combined with pulmonary infection were selected as our subjects.They were randomly divided into two groups and each group was 30 cases.Patients in western medicine group were given medicine plus placebo,and in Chinese medicine group were given west medicine combined with traditional Chinese medicine.Patients hospitalized for 4 weeks.WHO QOL-HIV plus AIDS-related quality of life scale were used to collect the information about quality of life.Results There were no significant difference between two groups in terms of quality of life,life activity,health status,sleep status,ability to work,leisure opportunities scores at before treatment (P ＞ 0.05).After treatment,the score of quality of life,life activity,health status,sleep status,ability to work,leisure opportunities in patients of Chinese group were (3.78 ± 0.69),(3.55 ± 0.67),(3.55 ± 0.67),(3.18 ± 0.72),(3.66 ± 0.70),(3.03 ± 0.73) respectively,higher than that of western medicine group ((2.90 ± 0.77),(2.75 ± 0.85),(2.75 ± 0.85),(2.85 ± 0.68),(3.35 ± 0.57),(2.95 ± 0.85) respectively,t =-2.791,-2.791,-4.28,-3.08,-4.08,-2.56,P ＜ 0.05).There were no significant differences between the two groups in the terms of the score of satisfaction,sex ability,HIV impaction on the body,the meaning of life,the energy aspects of patients at before treatment (P ＞ 0.05),but after treatment,these scores in Chinese medicine group were higher that in the control group ((3.51 ± 0.67) vs.(2.93 ±0.71),(3.13±0.46) vs.(2.86±0.74),(3.96±0.71) vs.(3.45 ±0.98),(3.66±0.72) vs.(3.23 ± 0.88),(3.23 ± 0.67) vs.(2.90 ± 0.65)),and the differences were statistically significant (t =-4.38,-2.34,-3.75,-2.76,-2.38,P ＜ 0.05).There was no significant difference in the term of the mental effect of HIV within groups at before treatment,but after treatment,the score in Chinese group was lower than the Western group ((3.05 ± 0.90) vs.(3.46 ± 0.87),t =2.31,P ＜ 0.05).Conclusion Chinese medicine combined western medicine can significant improve the quality of life of HIV patients with pulmonary infection.

ObjectiveTo investigate the diagnosis and treatment of gastric paralysis after gastric operation.MethodsThe clinical data of 21 patients with gastric paralysis after gastric operation were reviewed retrospectively.Results3.9% of patients occurred gastric paralysis in this group. The diagnosis was depended on patient's symptoms, X-ray graph of the upper digestive tract and gastroscopy. The patients were healed after conservative treatment.ConclusionThe combined conservative treatment is the ideal method to treat the gastric paralysis syndrome.

Objective: To observe therapeutic effects of ticagrelor combined tirofiban on patients with ST elevation myocardial infarction (STEMI) after percutaneous coronary intervention (PCI) and their short-term prognosis.Methods: A total of 280 STEMI patients undergoing emergency PCI were selected.According to random number table, patients were randomly divided into clopidogrel group (received clopidogrel combined tirofiban therapy) and ticagrelor group (received ticagrelor combined tirofiban therapy).TIMI blood flow grade of infarct related arteries, platelet aggregation rate and P2Y12 reaction unit (PRU) before and after PCI, and incidence of major adverse cardiovascular events (MACE) within 30d follow-up, hemorrhage event and cardiac function were measured and compared between two groups.Results: Compared with clopidogrel group after PCI, there was significant rise in percentage of TIMI blood flow grade 3 (81.4% vs.91.4%), and significant reductions in platelet aggregation rate [(55.2±4.1)% vs.(50.8±4.4)%] and PRU [(196.2±15.1)U vs.(180.8±12.0)U] in ticagrelor group, P<0.05 all.Compared with clopidogrel group after 30d follow-up, there were significant reductions in incidence rates of re-myocardial infarction (5.0% vs.2.9%) and cardiogenic death (2.9% vs.0.7%), left ventricular end-diastolic dimension [(53.1±2.8)mm vs.(49.0±2.0)mm] and left ventricular end-systolic dimension [(40.2±2.1)mm vs.(37.4±1.8)mm], and significant rise in left ventricular ejection fraction [(51.8±2.7)% vs.(55.4±2.5)%] in ticagrelor group, P<0.05 all.There were no severe hemorrhage events in both groups, and no significant difference in incidence rate of mild hemorrhage (5.0% vs.6.4%) between clopidogrel group and ticagrelor group, P=0.591.Conclusion: For STEMI patients undergoing emergency PCI, ticagrelor combined tirofiban can effectively reduce platelet aggregation rate, improve TIMI blood flow of infarct related arteries, therapeutic effects and their short-term prognosis without increasing hemorrhage risk, which is worth extending.
