To investigate the effects of Carvedilol on neurohormone and heart function in patients with congestive heart failure(CHF) by double blinded, randomized clinical trial. 35 congestive heart failure patients were double blinded and randomly divided into 2 groups, Carvedilol group and placebo group. 15 healthy persons constitute the normal control group. We measured the plasma concentration of norepinephrine(NE), angiotensin (Ang) and plasma renin activity (PRA) , meanwhile left ventricular ejection fraction (LVEF) , left ventricular dimension and volume were observed before and after treatment. The plasma concentrations of NE, Ang Ⅱ and PRA were found to be higher in patients with CHF than those of healthy control group ( P

Objective To study the incidence of malignant tumors in renal allografts and explore the mechanism of increased incidence.Methods A retrospective study was performed on 1 120 renal allografts under at least 0.5 year immunosuppression from 1978～2000. Results 47 cases of malignant tumors were found in 1 120 cases undergoing renal transplantation with the incidence being 4.2?%. 40 cases had intact medical history and 34 cases were demonstrated pathologically. Most patients accepted operations, additional therapies including chemical or radiological and immunological therapies. 25 cases survived and the longest survived time was 4.5 years. Conclusions The incidence of malignant tumors in renal allografts was higher than normal persons. Besides the outcome of immunosuppression, the effects of transplantation itself, such as oncogene chimera, transition of carcinogenic virus and so on, can not be neglected.

BACKGROUND: Plasminogen activator inhibitor 1 is the main regulator of the fibrinolytic system in vivo. The increase of plasminogen activator inhibitor 1 is closely related to thrombotic disease and it is also an independent risk factor for development of thrombotic disease.OBJECTIVE: To investigate the effect of huangqi(Astragalus), danggui (Angelica) and ligustrazine as medicines activating blood and eliminating stasis on the expression of plasminogen activator inhibitor 1 in HepG2 hepatocarcinoma cell strain.DESIGN: A randomized controlled study.SETTING: First Cadre Department of General Hospital of Chinese People' s Armed Police Force.MATERIALS: The experiment was completed in Academy of Military Medical Sciences of PLA from August to December 2004. HepG2 hepatocarcinoma cell strain was cultured. According to different drugs in culture medium, they were divided into six groups: control group, huangqi group,danggui group, huangqi + danggui group, compound danshen group and ligustrazine group.METHODS: Huangqi, danggui, huangqi + danggui, compound danshen and ligustrazine were added in HepG2 culture medium respectively. MTS assay was used to detect the effect of medicines activating blood and eliminating stasis on proliferation of HepG2 cells, plasminogen activator inhibitor 1 was assayed by specific enzyme-linked immunosorbent assays(ELISA),plasminogen activator inhibitor 1 activity was measured by amidolytical assay. 0.5 μg/mL of transforming growth factor β1 cells was added in HepG2 culture medium to stimulated production of plasminogen activator inhibitor 1. Control group was treated under the same conditions but without Chinese herbs.RESULTS: The inhibitory rates of cellular proliferation in huangqi and danggui groups werc(6.51 ±2. 66)% and (4.42 ±2. 19)%, but those in huangqi + danggui, compound danshen and ligustrazine groups were (12. 06 ±4. 98)%, (16. 38 ±4.06)% and(32. 83 ±9.8)% respectively,t = 2. 447 - 3. 707, P ＜ 0.05. Compared with the control group, huangqi,danggui, compound danshen and ligustrazine significantly inhibited plasminogen activator inhibitor 1 expression(22.68 ± 2.20, 11.11 ± 1.23,19.66±1.53, 15.45±1.27, 16.90±0.33, 14.01±0.74, t=2.447-3.707, P ＜ 0.05) and activity(2.16±0.014, 2.01 ±0.006, 1.95±0.014, 1.79±0. 104, 1.53±0.045, 1.48±0.012, t =2.447-3. 707,P ＜ 0.05) in HepG2 cells. The evident inhibitory effects were observed in the group of huangqi + danggui, especially in compound danshen and ligustrazine.CONCLUSION: The plasminogen activator inhibitor 1 expression and activity were inhibited effectively by huangqi, danggui, compound danshen and ligustrazine.

The State Key Specialized Scientific Projects bring the unprecedented opportunity for the development of variety disciplines and provide the critical timing for the improvement of science and technology of university. Meanwhile, it presents new challenges to develop the frontier of sciences and to promote cooperation and cross of different disciplines. Through the process of the programs, we will expect to train and find team leaders and outstanding scientists. This paper presented the brief outline how the researchers from the Departments of Infectious Disease and School of Pharmacy in Fudan University collaborated in a cross-discipline manner and integrated the research resources based on the objectives of the research programs. During the application, they reorganized research teams, combined the overlapping research fields to focus the direction of research fields according to the national and research needs. In the process of their application, they finally promoted the capacities for their competition and innovation which were undoubted to help us to establish headship/main forces in the fields of infectious disease precaution and devolvement of new clinical medicine in the future.

AIM To explore the mechanism of amyloid β-protein fragment 25-35(Aβ25-35)-induced inflammation and apoptosis in rat hippocampus in vivo by studying mitogen-activated protein kinase (MAPK) signaling pathway and the protective effect of anti-inflammatory drug ibuprofen. METHODS Rats were given ibuprofen (7.5 mg·kg-1 daily, ig) for 3 weeks prior to and 1 week after icv single dose of Aβ25-35 (10 μL, 1 mmol·L-1). Seven days after injection, Nissl staining and immunocytochemical technique were employed to determine the morphology of pyramidal neurons and astrocyte infiltration in hippocampal CA1. The expressions of IL-1β, extracellular signal-regulated kinase (ERK), p38 MAPK, PKC, and caspase-3 were determined by Western blot. Reverse transcription-PCR analysis showed changes in IL-1β mRNA level. RESULTS Intracerebroventricular injection of Aβ25-35 elicited astrocyte activation and infiltration and caused a strong inflammatory reaction characterized by increased IL-1β production and elevated IL-1β mRNA level. The inflammatory reaction was accompanied by the loss of pyramidal neurons in hippocampal CA1. The phosphorylation of p38 MAPK was significantly increased, on the other hand, the phosphorylation of ERK was significantly reduced and these were coupled with the increase of caspase-3 expression in hippocampal CA1. Ibuprofen (7.5 mg·kg-1 daily, 4 weeks) significantly reduced Aβ-induced IL-1β expression, caspase-3 expression and p38 MAPK activation. The loss of pyramidal neurons was also significantly attenuated by treatment with ibuprofen. CONCLUSION The activation of p38 MAPK and the down-regulation of ERK play a pivotal role in the inflam-matory response and apoptosis evoked by Aβ25-35 in vivo, which can be prevented by ibuprofen.

AIM: To determine the relevance of NADPH oxidase subunit p22hox and the expression of superoxide anion on ventricular remodeling in myocardial infarction (MI) rats. METHODS: MI of Sprague-Dawley rats were established by left anterior descenting coronary artery ligation. 8 weeks after MI, Doppler echocardiography, hemodynamic study and histomorphometry were performed to analyze the ventricular remodeling. The level of thiobarbituric acid reactive substance in plasma and myocardium were measured, and the distribution of superoxide anion was observed with laser scanning confocal microscope. The expression of p22phox mRNA and protein level was detected by RT-PCR and immunohistochemistry. RESULTS: The left ventricular remodeling was significant in MI rats, also the level of thiobarbituric acid reactive substance increased in the plasma and non-infarcted myocardium. The expressions of p22-phox mRNA and protein levels, and superoxide anion increased in infarcted and non-infarcted myocardium in MI rats. CONCLUSION: Our results suggest that the expression of NADPH oxidase and its derived superoxide anion may take part in left ventricular remodeling through oxidative stresss after MI.
