Objective To observe the effect of levocamitine on cardiac function of patients with dilated cardiomyopathy (DCM).Methods 40 patients with DCM were randomly divided into control group (n =20) and the experimental group(20 cases).Control group was given conventional drug such as digitalis,furosemide,benazepril hydrochloride,antisterone for treatment,the experimental group was given levocarnitine on the basis of control group.The treatment efficacy and the situation of cardiac function were compared between the two groups.Results The total effective rate was 95.0％ and 80.0％ in the experimental group and the control group,respectively,the difference was statistically significant(x2 =10.286,P ＜ 0.01).Compared with the control group,the parameters of stroke volume,cardiac output,ejection fraction,and left ventricular fractional shortening rate were significantly increased in the experimental group after treatment(all P ＜ 0.05).Conclusion Levocarnitine can improve cardiac function based on the conventional treatment.

High-dose melphalan (Mel) is considered as a current standard preparative regimen in autologous stem cell transplantation (ASCT) for multiple myeloma (MM). Irradiation in total body (TBI) combined with Mel is not superior to Mel alone, and the adverse reactions are increased at the same time. The efficacy of 200 mg/m2 Mel is much better than that of 100-140 mg/m2 Mel in young patients. Several regimens including MelBU, TBC, BCV, MET, MTC, MelBCNU, VMel, MTC as well as bendamustine have similar treatment outcomes compared with 200 mg/m2 Mel. Other strategies need to be evaluated in different trials.

Objective: To assess the feasibility and accuracy of real-time three dimensional echocardiography (RT-3DE) in quantitative evaluation of left ventricular (LV) volume and ejection fraction (EF) in patients with ventricular aneurysm and myocardial infarction. Methods: Twenty-three p atients with left ventricular aneurysm combined with myocardial infarction were examined by RT-3DE, two dimensional echocardiography Simpson's method, and M-mode Teichholz method separately. The following parameters: left ventricular end diastolic volume (LVEDV), end systolic volume (ESV), stroke volume (SV) and EF were obtained by each method and the results were compared with those obtained by left ventriculography (LVG). Results: The values of LVEDV, LVESV, SV, and EF determined by RT-3DE showed good correlations with those determined by LVG (r=0.92, 0.90, 0.88, and 0.91, respectively; P<0.001), with the values by RT-3DE slightly smaller than those by LVG(P>0.05). The values of LVEDV, LVESV, SV, and EF determined by Simpson's method also showed good correlations with those determined by LVG (r=0.85, 0.87, 0.86, 0.91, respectively; P<0.001), with the values by Simpson's method smaller than those by LVG (P<0.05 for LVEDV and LVESV). The values of LVEDV, LVESV, SV, and EF determined by M-mode Teichholz method also showed good correlations with those determined by LVG (r=0.73, 0.71, 0.70, 0.65, respectively; P<0.05), with the values by M-mode Teichholz method larger than those by LVG(P<0.05 or P<0.01). Conclusion: RT-3DE is a more accurate for evalua tion of LV volume and EF in patients with aneurysm combined with myocardial infarction.

Objective:To evaluate the effect of percutaneous coronary intervention (PCI) on mitral regurgitation (MR) in patients with acute myocardial infarction (AMI). Methods: A total of 213 AMI patients were divided int o PCI group (n = 87, PCI + medication) and medication group(n= 126, medication) according to the treatments they received. Echocardiographic examination was conducted in patients during admission and 6 months follow-up. Color Doppler was used to determine the degree of MR. Echocardiogram indices included MR degree, left ventricular end-diastolic diameter (LVEDd) ,left ventricular end-systolic diameter (LVEDs) ,left ventricular end-diastolic volume (LVEDV) ,left ventricular end-systolic volume(LVESV) ,and left ventricular ejection fraction (LVEF). Results: The overall incidence of MR was 28. 6% in 213 patients during admission. The MR incidence in patients with acute inferior myocardial infarction was higher than that in patients with other parts of infarction (34. 5% vs 22. 3% PO. 05), while the incidence in medication group increased significantly than that during admission(43. 7% vs 30. 2%,P

BACKGROUND: Adolescent Intemet addition disorder(IAD) gradually appears with the rapid popularization of Internet in China. National researches are rare at present.OBJECTIVE: To analyze the status quo of Internet use and on-line behavior characters of college students and to provide scientific data for the prevention of adolescent IAD.DESIGN: A status quo survey by employing college students as subjects SETTING: Department of psychiatrics of a medical university-affiliated hospitalPARTICIPANTS: Totally 510 college students were selected from three different type universities of Shanxi province including Shanxi Medical University, Taiyuan University of Technology, Shanxi University of Finance and Economics between November 2003 and February 2004.METHODS: Totally 510 college students from three universities of Shanxi Province were assessed by IAD test and self-compiled questionnaire for on-line college students.and non-IAD students.RESULTS: The detectable rate of IAD in college students of Shanxi province was 6.2%. More male students( n =29) had IAD than female students ( n = 3 ). Weekly on-line time of IAD students was (18.59 ± 16. 12)hours, which was significantly longer than (5.61 ± 5.64) hours of non-IAD student( P ＜ 0. 001 ) . There were significant differences of monthly on-line expenses, usual on-line place, opinions of whether intemet had negative impacts, understanding of their parents on internet functions they used, and the objective of on-line between IAD students and non-IAD students(P＜0.05 -0. 001 ), while there were no significant differences of on-line history and the utilization of internet function between two groups of students ( P ＞ 0. 05).CONCLUSION: The detectable rate of IAD in college students is relatively high and there is significant difference of on-line behavior characters between IAD students and non-IAD students, which should arouse attentions from the related department to prevent the occurrence of IAD.
