Objective To study the inducing apoptosis effect of a traditional Chinese medicine gambogic acid (GA) on Raji cell line and its mechanism. Methods The effect of GA on the proliferation of human peripheral blood mononuclear cells induced by lipopolysaccharide (LPS) was analyzed. Raji cells were treated with GA at different concentrations and times, and the inhibitory effect was detected by MTT assay.Apoptosis induced by GA was observed by Annexin V/PI doubling staining and flow cytometry assay.Mitochondrial membrane potential was measured by JC-1 assay. Activated Caspase-3, Caspase-8 and Caspase-9 in living Raji cells were measured by caspGLOWTM fluorescein staining kit and quantificated by flow cytometry. Results After incubation with GA, the proliferation rates of both normal blood mononuclear cells and Raji cells were dramatically inhibited in a concentration dependent manner. GA induced Raji cells to undergo apoptosis. GA decreased the mitochondrial membrane potential of Raji cells. GA increased the level of activated caspase 3, caspase 8, caspase 9 for 0.37 %, 33.57 %, 18.27 % in 24 h and 28.2 %, 69.2 %,76.7 % in 48 h respectively. Conclusion GA have an inhibitory effect on Raji cells, and can trigger apoptosis of Raji cells through both intrinsic and extrinsic pathways.

BACKGROUND: Left ventricular hypertrophy (LVH) is an important ring-joint of congestive heart failure (CHF). It is also considered to be independent risk factor of cardiovascular disease, so how to reverse or relieve LVH is valuable to cure CHF.OBJECTIVE: To observe the effect of Lujiao prescription on degree of LVH in patients with CHF.DESIGN: A random-control observation on CHF patients.SETTING: Department of Cardiovasology, Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine.PARTICIPANTS: A total of 20 patients with CHF were selected from the Special Clinic and Department of Cardiovasology in Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine from January 1996 to December 1998. All of them were consistent with the Framirham diagnostic criteria and following standardizations: ①above Ⅲ degree of cardiac functional grading by New York Heart Association (NYHA);②over 3 months case history;③accepted basic treatment of quantity sufficient diuretic and vasodilating agent excluding angiotensin converting enzyme inhibitor (ACEI);LVH was proved by echocardiogram or chest X-ray. They were informed of treatment items and consented.METHODS: According to random lot, the patients were divided into Lujiao prescription group and Digoxin group, each containing 10 patients.①Oral administrations of Lujiao prescription (35 mL, two times per day, produced by Shanghai Shuguang Hospital) and Digoxin (0.125-0.25 mg per tablet, batch number: 970757, once daily) were given in the corresponding groups, and the treatment duration was 3 months. After treatment, all the patients were detected in①NYHA cardiac functional grading; ②interventricular septal thickness (IVST) and posterior wall thickness (PWT) in diastolic phase through echocardiogram, myocardium weight of left ventricular by Devereux formula, left ventricular mass index (LVMI) corrected by bodysurface area, and degree of LVH;③the level of plasma angiotensin Ⅱ (Ang Ⅱ ) by radioactive immunoassay.MAIN OUTCOME MEASURES: NYHA cardiac functional grading, e-chocardiogram (IVST, PWT, LVMI, degree of LVH), the level of plasma Ang Ⅱ.RFSULTS: All 20 adopted patients entered the result analysis.①The classification of NYHA cardiac functional grading ( Ⅰ , Ⅱ ,Ⅲ,Ⅳ) were respectively 2, 5, 3, 0 case in Lujiao prescription group and 2, 4, 4, 0 case in Digoxin group after treatment, and difference was significant compared with those before treatment (0, 0, 7, 3, P ＜ 0.05).②IVST, PWT and LVMI of Lujiao prescription group were obviously decreased after treatment [(11.20±0.42), (12.10±0.32) mm, P ＜ 0.01; (10.60±0.84), (11.40±1.10) mm,P ＜ 0.01; (139.4±12.4), (155.3±15.4) g/m2, P ＜ 0.01], while those of the Digoxin group were untouched (P ＞ 0.05). The degree of LVH of Lujiao prescription group after treatment was obviously decreased [normal, mild,moderate, sever: 2, 6, 2, 0; 0, 3, 4, 3, P ＜ 0.01], while that of the Digoxin group was not obviously decreased (P ＞ 0.05).③)The level of plasma Ang Ⅱin the Lujiao prescription group was obviously decreased [(97.7±19.5),(144.0±18.5) ng/L, P ＜ 0.01], while that of the Digoxin group was not obviously increased (P ＞ 0.05).CONCLUSION: Lujiao prescription can reverse or relieve the degree of LVH in patients with CHF.

To investigate the relationship of the variation of virulence and the external capsid proteins of the pandemic duck hepatitis A virus type 1(DHAV-1) isolates,the virulence,cross neutralization assays and the complete sequence of the virion protein 1(VP1) gene of nine virulent DHAV-1 strains,which were isolated from infected ducklings with clinical symptoms in Shandong province of China in 2007-2008,were tested.The fifth generation duck embryo allantoic liquids of the 9 isolates were tested on 12-day-old duck embryos and on 7-day-old ducklings for the median embryonal lethal doses(ELD50s) and the median lethal doses(LD50s),respectively.The results showed that the ELD5s of embryonic duck eggs of the 9 DHAV-1 isolates were between 1.9 × 106/mL to 1.44 × 107/mL,while the LD50s were 2.39 × 105/mL to 6.15 × 106/mL.Cross-neutralization tests revealed that the 9 DHAV-1 isolates were completely neutralized by the standard serum and the hyperimmune sera against the 9 DHAV-1 isolates,respectively.Compared with other virulent,moderate virulent,attenuated vaccine and mild strains,the VP1 genes of the 9 strains shared 89.8％-99.7％ similarity at the nucleotide level and 92.4％-99.6％ at amino acid level with other DHAV-1 strains.There were three hypervariable regions at the C-terminus(as 158-160,180-193 and 205-219) and other variable points in VPI protein,but which didn't cause virulence of DHAV-1 change.
