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: Apolipoprotein E (ApoE) gene polymorphism is associated with the onset of Alzheimer disease (AD), most of the researchers reported that ApoE ε4 allele accounts for familial AD as well as for sporadic AD.OBJECTIVE: This study was designed to validate the relationship between ApoE gene polymorphism and the sporadic AD in Aged Adults in Urumqi, and to evaluate the value of ApoE gene for prediction the risk of sporadic AD.DESIGN: Controlled comparative study based on patients.SETTING: It was conducted at the Institute of Clinical Medicine and the Neurological Department of Urumqi General Hospital of Lanzhou Military Area Command of Chinese PLA.PARTICIPANTS: From January 2001 to January 2003, 60 aged inpatients and outpatients at the Neurological Department of Urumqi General Hospital of Lanzhou Military Area Command of Chinese PLA and elderly in the Old People's Home were screened for AD. Of all these participants,28 were males and 32 were females, with an age from 52 to 91, in average of (74.2±19.5) years old, They had 0-16 years education, in average of 4.43 years, 28 were illiterate, 13 were at primary school educational level,12 were at junior middle school educational level, 4 were at high school educational level and 3 were at college educational level. From February to December 2002, 90 genetically unrelated individuals with healthy physical examination findings in Xinjiang area were selected into control group, 59males and 31 females, with an age from 50 to 101 years old, in average of (69.9±25.5) years old, have 0-16 year's education, in average of 7.96years. Of all the controls, 14 were illiterate, 23 were at primary educational level, 25 were at junior middle school educational level, 21 were at high school educational level and 7 were at college educational level. Informed consents were obtained from all the participants.METHODS: 5 Ml blood samples, anticoagulated with ethylene diamine tetraacetic acid (EDTA), were drawn from each participant. Then genome DNA was extracted from peripheral white blood cells using the phenolchloroform method. A fragment containing polymorphism site in exon 4 of ApoE were amplified using the polymerase chain reaction (PCR), were digested with Hha I and were identified using electrophoresis and silver staining. Then, ApoE genotypes and the frequency of ApoE alleles were compared between AD group and control group.MAIN OUTCOME MEASURES: ① ApoE genotypes and the frequency of ApoE alleles were measured in AD group and control group. ② The frequency of ApoE alleles were calculated in participants with different sex,age and educational level in AD group and control group.RESULTS: Sixty patients with AD and 90 healthy individuals participated this investigation. All of them entered the statistical analysis procedure.① The frequency of ε3/ε4 and ε4/ε4 alleles was higher in AD group than in control group (26.67%,11.11%; 3.33%, 1.11%; P < 0.05). The frequency of e2/ε3 in AD group were lower than control group (5.00%,14.00%, P <0.05). ② The frequency of ApoE ε4 allele were higher in AD group as compared with control group (17.50%, 7.22%, P < 0.05). The frequency of ApoE ε2 allele were lower in AD group (6.67%, 13.33%, P < 0.05). ③ The frequency of ApoE ε4 allele in females were higher in AD group than in control group (20.97%, 5.00%, P < 0.01). ④ In AD group, patients ≥ 75 years old have a lower frequency of ApoE ε4 allele compared to those less than 75 years (8.57%, 30.00%, P < 0.01). And in individuals less than 75 years old, the frequency of ApoE ε4 allele were higher in AD group than that in control group (30.00%, 7.02%, P < 0.01). ⑤ In illiterate persons and the individuals with only primary school educational level, the frequency of ApoE ε4 allele were higher in AD group than that in control group (10.00%, 0.56%, P < 0.001; 5.00%,1.12%, P < 0.01).CONCLUSION: ① It is proved that ApoE ε4 allele is significantly associated with sporadicAD in Urumqi and ε3/ε4 is the major genotype. ② ApoE ε2 allele has a protective effect on onset of AD. ③ Those individuals,female,less than 75,lower educational level or carrying ApoE ε4 allele take a higher risk of AD.

BACKGROUND: Congestive heart failure (CHF) is the clinical syndrome of all kinds of heart disease on the serious or final stage. About half of patients with organic heart disease will have heart failure that has a high incidence rate and mortality. The survival of heart failure was inferior to that of malignant tumor.OBJECTIVE: To confirm the clinical effect of Lujiao prescription on CHF and elucidate its possible mechanism.DESIGN: A control observation on CHF patients.SETTING: Department of Cardiovasology, Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine.PARTICIPANTS: A total of 60 patients with CHF were selected from the department of cardiovasology in Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine from January 1996 to December 1998. There were 31 male and 29 female. Included criteria: ①All of patients were consistent with Framinham diagnostic criteria. ② Above Ⅲ degree by New York Heart Association(NYHA). ③ Three months case history. ④Accept quantity sufficient diuretic and vasodilating agent (exclude angiotensin converting enzyme inhibitor ). ⑤ Left ventricle hypertrophy was proved by echocardiogram or chest X-ray. ⑥ Differentiation of symptoms and signs of Traditional Chinese Medicine refers to asthenia syndrome of differentiation of symptoms and signs of Traditional Chinese Medicine (1986, Researching Association of Chinese integrated medicine) General state of health and basic disease of the patients in the two groups were not significant deviation.METHODS: 60 patient s of CHF were randomly divided into Lujiao prescription group(n=40) and Digoxin group (n=20) at the rate of 2:1. Lujiao prescription group: Orally liquid decoction of Lujiao Prescription 35 mL (1 mL contain crude drug 1.6 g) Bid. po. Course of treatment: 4 weeks. Digoxin group: Digoxin tablet, 0.125-0.25 mg, qd. po. course of treatment: 4 weeks.After 4-week treatment, the patients' clinical effect, integrals of the symptoms of renal deficiency, classification of function capacity of the NYHA,Lee's heart failure score, heart rate(HR), myocardium oxygen consumption (MOC), proportion of heart to chest, echocardiogram, measurement of plasma angitention Ⅱ (Ang Ⅱ ) and plasma atrial natriuretic factor (ANF) were observed.MAIN OUTCOME MEASURES: ① The total clinic effective rate. ②Integrals of the symptoms of renal deficiency. ③ Classification of function capacity of the NYHA. ④ Lee's heart failure score. ⑤HR and MOC. ⑥The proportion of heart to chest. ⑦ Ejection fraction(EF), cardic output (CO), interventricular septal thickness (IVST), posterior wall thickness (PWT) and left ventricular mass index (LVMI) through echocardiogram. ⑧The measurement of plasma Ang Ⅱ and plasma ANF.RESULTS:Totauy 60 patients entered the final analysis. ① The total clinical effective rate of the Lujiao prescription group was 90 %, which showed no significant difference from the Digoxin group (90 %, P > 0.05).② Improvement was significantly observed in the integrals of the symptom of renal deficiency of the patients in the Lujiao prescription group after treatment (P < 0.01), but which was not significant in the Digoxin group(P> 0.05). ③ It was found that classification of functional capacity of NYHA between Lujiao prescription group and Digoxin group after treatment was obviously decreased (P < 0.01). ④ Lee's heart failure score of patients in Lujiao prescription group and Digoxin group after treatment was decreased (P < 0.01). ⑤Myocardium oxygen consumption and HR of the patients in the Lujiao prescription group and Digoxin group after treatment was decreased (P < 0.01). ⑥ The proportion of heart to chest between Lujiao prescription group and Digoxin group after treatment was decreased (P < 0.01).⑦ EF and CO were increased by Lujiao prescription and by Digoxin (P< 0.01,vs pretreatment, respectively). IVST, PWT, LVMI of Lujiao prescription group after treatment were obviously decreased (P < 0.01), while those of the Digoxin group were not obviously decreased (P > 0.05). ⑧ Thlevel of plasma Ang Ⅱ of the patients in the Lujiao prescription group after treatment were obviously decreased (P < 0.01), while that of the Digoxin group were not obviously decreased (P > 0.05). The level of plasma ANF was decreased by Lujiao prescription and by digoxin(P < 0.01, vs pretreatment, respectively).CONCLUSION: There is increasing cardiac constriction power and regressing left ventricular hypertrophy of patients with CHF by Lujiao prescription. The therapeutical effect of Lujiao prescription for CHF is better than that of Digoxin. The effect may be related to the regulation of circular or local endocrine(plasma Ang Ⅱ and ANF) disorder.
