Objective To explore the effects of fosinopril and metoprolol on cardiac remodeling and the plasma levels of angiotensin II(AngⅡ),endothelin-1(ET-1) and nitric oxide(NO) in patients with congestive heart failure(CHF).Methods A total of 80 patients with CHF were divided into 3 groups,fosinopril(20 mg/d),metoprolol(from 6.25 mg,twice a day to 100 mg,twice a day or the highest tolerant dose) and combination groups(as in single use),and all were treated for 12 months.Electrocardiography including ejection fraction(EF)and left ventricular end diastolic diameter(LVEDD)was carried out,and plasma levels of the 3 neurohormones were detected with conventional methods at admission and 12 months after the treatment.(Results Plasma) levels of AngⅡ,ET-1 and NO were decreased significantly in all groups.No significant difference was seen between fosinopril and metoprolol groups,but the plasma levels was decreased remarkably(P

Objective To prospectively assess the association between cardiac resynchronization therapy (CRT )and left atrial volume .Methods Fourteen patients with chronic heart failure ,sinus rhythm and left bundle branch block were enrolled in this study and prepared for CRT implantation .Clinical and echocardiographic evaluations were performed before CRT implantation and 6 months later .Followings were parameters of the left atrial and left ventricular volume:left ventricular end-systolic volume index (LVESVi)and end-diastolic volume index(LVEDVi) ,maximal LAV index(iLAVmax) ,etc ,LAV index before atrial systole(iL-AVpre)and minimal LAV(iLAVmin) .CRT responders were defined as those whose reduction rates were more than 10% in iL-VESV in 6-month follow-up .Results Responders(71 .4% )and non-responders(28 .6% )had similar baseline ,clinical characteristics and pre-implantation LV volumes .However ,iLAVmax in the responders was remarkably lower than that in non-responders .CRT therapy significantly reduced LVESVi(P<0 .01) ,LVEDVi(P<0 .001) ,iLAVmax(P=0 .004) ,iLAVpre(P=0 .003)and iLAVpost (P<0 .01) ,but when compared with the non-responders ,iLAVmax was much lower in responders .Correlation analysis showed that there was a significant correlation of LVEDVi with iLAVmax ,iLAVpost(P<0 .05) .Conclusion CRT therapy can significant-ly improve iLAVpre and iLAVmax may be a predictor of LV reverse remodeling .

Objective To evaluate the accuracy of lung volume in pneumothorax by CT.Methods 1.17 artificial lung models were scanned by SHIMADZU SCT-7000 TH whole body scanner system and their volumes were determined by using the volume-calculated function of CT.2.The actual volume of the models were equal to the volume of water injection by the models.Results The actual and calculated volumes of lung were 2893.47?29.22 ml and 2894.32?28.47 ml respectively.A good correlation(?=0.9860,?

In order to complete the seven-year microbiology teaching better,we used the theme discussion of PBL teaching in our teaching activities,i.e.by setting a certain scenario and giving some background information before the students'group discussion. The practice proved that the theme discussion of PBL teaching method in theoretical teaching and learning changed the traditional case-based discussion chiefly by teachers; as a result,the relative immobilization of the teaching mode became more flexible. These methods of teaching and learning not only stimulated the students'initiative and enthusiasm,but also helped them to think critically. Our assessment of PBL teaching and learning showed that the themes discussion of PBL in medical microbiology achieved better results.

Objective To explore the effect of diversified and teamwork health education mode on disease-related knowledge of coronary artery disease patients.Methods 147 cases of patients with coronary artery disease hospitalized in the general hospital of Tianjin medical university were divided into the treatment group which was given diversified health education of teamwork mode and the control group which was given traditional health education.The self-designed questionnaire was used to evaluate the effect of teamwork health education mode.Results Level of knowledge in the treatment group was significantly improved when compared with the control group,the increase amplitude of knowledge level in the treatment group was higher than the control group,and the scores of the treatment group were higher than the control group in the dimensions of diet,prevention,clinical manifestation,treatment,activity,the differences were statistically significant.Conclusions With diversified,multidisciplinary,and teamwork health education mode the patients' level of knowledge was significantly improved,the correct and positive awareness about disease were increased,and the patients were urged to take healthy behavior,so that their physical and mental state will maintain the best.

Objective To summarize the effect and experience of nursing of patients with rheumatic valvular heart disease with atrial fibrillation treated with Cox Ⅲ labyrinth and simultaneous valve replace-ment operation. Methods A retrospective analysis was carried out in the nursing of 58 patients with rheumatic valvular heart disease with atrial fibrillation treated with Cox Ⅲ labyrinth and simultaneous valve replacement operation in our hospital from April 2006 to July 2008. Results One patient died of periop-erative renal failure,one died of low cardiac output,one died of infectious endoearditis.Tbe mortality rate reached 5.2%.Other patients were discharged from hospital after completely cured.The survived patients maintained sinus rate during hospitalization days after operation and short-term follow-up after being dis-charged.Among 43 patients who completed follow-up of 6 months after operation,3 patients (7.0%) damon-strated atrial fibrillation,while others still kept sinus rate. Conclusions Attention should be paid to psy-chological nursing,respiratory tract preparation,cardiac function monitoring and nursing of anticoagulation treatment for patients treated with Cox Ⅲ labyrinth and simultaneous valve replacement operation.

Objective To establish a method for determination of chrysophanol,emodin and rhein in Huangzhi capsules.Method Chrysophanol,emodin and rhein in Huangzhi capsules was determined by TLC-scanning with a mixture of n-hexane-ethylacetate-formic acid(30∶10∶0.5) as the developing system.The detection wavelength was 435 nm and 610 nm.Results The calibraction curve of chrysophanol,emodin and rhein was linear in the range of 0.014 65～0.073 25,0.013 35～0.066 75,0.012～0.072 ?g respectively.Conclusion The method was simple,accurate with good repeatability,and suitable for the content determination of chrysophanol,emodin and rhein in Huangzhi capsules.

Objective To study the possibility of targeting endothelial cells with the 131I labeled monoclonal antibody (mAb) for the treatment of hepatocarcinoma. Methods An animal model of human hepatocarcinoma in nude mice was reproduced, and tumor inhibiting activity of the 131I labeled mAb was tested. 30 nude mice with hepatocarcinoma were randomly divided into 3 groups: in group A the mice were treated with mAb 200?g/200?l twice a week; group B mice were treated with the 131I labeled mAb 200?g/200?l twice a week; control group mice were given normal saline in equal volume. Tumor growth in mice was observed. After the mice were sacrificed, the tumor was histologically examined and the intra-tumor microvessel density (TMVD) recorded. Results The tumor growth inhibition effect in mice treated with mAb was 74.55%. This effect was enhanced when treated with the 131I labeled mAb, as evidenced by an increase of tumor growth inhibition rate to 86.36%. Pathologically, Massive necrosis of tumor cells around the degenerated vessels was observed in the mAb treated mice. TMVD was significantly lower in the mAb treated mice than that in the untreated mice (P
