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 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,?

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 .

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 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.

Abnormal cell signal transduction is associated with the occurrence and development of human diseases. Some virus pathogenicity and infection mechanism are due to virus antigen protein acting on the host cell signal transduction pathway, leading to host cell signal transduction disorder. Hepatitis C virus (HCV) is a major pathogen of chronic hepatitis C, which causes cirrhosis and hepatocellular carcinoma. But the pathogenesis of HCV and persistent infection mechanism remain far from clear. HCV pathogenesis may be related to the HCV protein expression interfering host cell signal transduction pathways. The studies of hepatitis C virus proteins acting on host cell signal transduction pathways, not only help to clarify the impact of its pathogenic mechanisms, but also benefit to new drug design and development for new treatment methods. This article summarizes the recent progress in research on the effect of hepatitis C virus protein in cell signal transduction pathways in the past few years.

Objective: To observe the curative effect of image guided radiation therapy on orbital inflammatory pseudotumors. Methods:28 cases of orbital inflammatory pseudotumors in our hospital from September 2009 to September 2012 were treated with image guided radiation therapy (IGRT) with a single dose of 2GY/F, 1F/d and a total dose of 20GY/10F. Radiation therapy was completed in 2 weeks at 10 times. Results: 23 patients (82%) were completely cured and 3 patients (11%) were partly cured with the total efficiency of 93%. Conclusion:After IGRT treatment, the symptoms in the patients like eye pain, exophthalmos, eye movement disorders and other symptoms were disappeared. IGRT could relieve pain, improve the cure rate and reduce recurrence.

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.
