Four kinds of ionic liquids [BMIM] Br, [BMIM] BF4, [BMIM] PF6, [HMIM] PF6 were used to analyze the content of oleanic acid and paeoniflorin in Paeonia lactiflora with ultrasonic-assisted extraction coupled with HPLC. The chromatographic column, Purospher star RP-C18 (4.6 mm x 250 mm, 5 μm), was used. Acetonitrile and water (90:10) as mobile phase was used to determine the content of oleanic acid with a gradient elution and flow rate at 1.00 mL · min(-1), detection wavelength at 210 nm, chromatographic column temperature at room temperature. Paeoniflorin content was determined using acetonitrile and water (18:82) as mobile phase with a gradient elution and flow rate at 1.00 mL · min(-1), detection wavelength at 250 nm, the chromatographic column temperature at room temperature. The result show that oleanic acid has the highest extraction yield when the conditions are solid-liquid ratio of 1:80 (g · mL(-1)), and the [BMIM] Br methanol solution concentration of 0.6 mol · L(-1). Under the optimal extraction conditions, the content of oleanic acid from 0.24 to 3.76 μg showed a good linearity (r = 0.9999), the average recovery was 97.20%. Paeoniflorin has the highest extraction yield when the conditions are solid-liquid ratio of 1:130 (g · mL(-1)), and the [C4 MIM] PF6 methanol solution concentration of 0.6 mol · L(-1). Under the optimal extraction conditions, paeoniflorin content from 0.42 to 4.20 μg showed a good lin- earity (r = 1.000), the average recovery was 98.84%. This method is simple and reliable, its repeatability is also very good. It has important significance in the study P. lactiflora of ionic liquid microextraction.

OBJECTIVETo investigate the effect of Luteolin alone or combination with chemotherapentic drugs on the cytoxicity of cancer cells.

METHODSCultured A549, Hela, MCF-7, AGS, MGC-803, Caco2 and HepG2 cells were treated with Luteolin or the combination of Luteolin with other chemotherapeutic agents (Bexarotene, Cisplatin and Bleomycin). Cell viability was measured by MTS assay and IC(50) was calculated.

RESULTSThe IC(50) of Bexarotene to Hela cells was 2 micromol/L, but with the combination of 5 micromol/L of Luteolin that reduced to 0.2 micromol/L. However, the combination of Bexarotene and Luteolin did not show significant benefit in MGC-803, HepG2 cells, Caco2 and MCF-7 cells. The IC(50) of Cisplatin to Hela cells was over 30 micromol/L,but it decreased to 3 micromol/L in the presence of 5 micromol/L Luteolin; Luteolin also sensitized Cisplatin in MGC-803, HepG2 and A549 cells studied. The IC(50) of Bleomycin to Hela cells was over 100 micromol/L, but it was about 1 micromol/L in the presence of 5 micromol/L Luteolin. A549 cells were resistant to Bleomycin with an IC(50) of 100 micromol/L, 10 micromol/L Luteolin greatly enhanced the cytotoxicity of Bleomycin to the cells with the IC(50) of about 10 micromol/L. The inhibitions of MGC-803, HepG2, A549 and AGS cells didn't change by combination of Luteolin.

CONCLUSIONLow concentration of Luteolin has little toxic effect on the cancer cell lines tested in the study, but it can sensitize chemotherapeutic drugs in various cancer cell lines.

Objective To investigate the prevalence of hypertension among residents over 18 years of age in Shigatse, Tibet, and to explore the correlation between different influencing factors and the incidence of hypertension. Methods A questionnaire survey and field blood pressure measurements were used to collect the information of age, education, occupation, smoking, drinking, body mass index (BMI) and salt intake were collected from 391 residents in Shigatse area. Logistic regression analysis of SPSS was used for statistical analysis. Results 391 questionnaires showed that the prevalence of hypertension was 38.36%, of which 39.91% was male and 36.52% was female. The results of multivariate Logistic regression analysis showed that the factors associated with hypertension in Shigatse residents included age, BMI, smoking and drinking, in which age and BMI, smoking were positively correlated with hypertension. Alcohol consumption was negatively correlated with hypertension. Conclusion In Shigatse area, age, BMI and smoking were the risk factors of hypertension, while drinking alcohol was protective factor of hypertension.

OBJECTIVETo investigate the efficiency of multiplex ligation-dependent probe amplification (MLPA) combined with short tandem repeat (STR) linkage analysis for the prenatal diagnosis for Duchenne muscular dystrophy (DMD).

METHODSGender of the fetus was first determined by the presence of Y chromosome sex-determining gene (SRY). Subsequently, combined MLPA and STR linkage analysis were applied for the probands, pregnant women and fetuses in 45 affected families.

RESULTSAmong the 45 families, 31 SRY-positive fetuses were identified, among whom six were diagnosed with DMD. For 14 SRY-negative fetuses, four were diagnosed as carriers. The remainders were normal.

CONCLUSIONMLPA can detect mutations in the exons of dystrophin gene, whilst STR linkage analysis can determine whether the fetus has inherited the maternal X chromosome bearing the mutant gene. As the result, the method can detect affected fetuses in which no exonic mutations are detected with MLPA. By combining the two methods, the diagnostic rate for DMD can be greatly improved.

OBJECTIVETo locate the cluster region of loss of heterozygosity (LOH) in children with acute lymphoblastic leukemia (ALL), and explore the new tumor suppressor gene.

METHODSAllelic loss was analyzed by PCR with 15 microsatellite markers mapping on 6q16.3. The LOH was analyzed by bioinformatics. The relationship between LOH and clinical factors was further analyzed.

RESULTSThe frequency of LOH at least at one loci on 6q16.3 was 32.7%. The LOH in relapsed patients was higher than those in not relapsed. The higher frequency of LOH was observed in two regions of D6S1709-D6S1028 and D6S2160-D6S1580 at 6q16.3. GRIK2 may be a candidate of tumor suppressor gene. There are 12 ESTs may carry out new anti-oncogene. Patients with 6q LOH had higher WBC counts (P < 0.01), blast cells percentage (P < 0.01), relapse rate (P < 0.05) and chromosomal aberration (P < 0.05).

CONCLUSIOND6S1709-D6S1028 and D6S2160-D6S1580 are two regions of minimus deletion on 6q16.3 in which tumor suppressor gene may exist. The LOH on 6q16.3 may be a prognostic index of children with ALL.

This study was purposed to explore the expressions of platelet-activated markers PAC-1 and CD62p in peripheral blood of malignant lymphoma patients and the influence of dipyridamole on their expression. 32 lymphoma patients were divided into simple chemotherapy group (simple group) and chemotherapy plus dipyridamole group (combined group) randomly, and 15 healthy peoples were selected as control group. The dipyridamole of 100 mg/day was given to the patients in combined group. The expression levels of PAC-1, CD62p and fibrinogen (Fib) were detected by flow cytometry and magnetic bead method on day 0, 3, 7 and 14 of chemotherapy respectively. The results showed that the levels of PAC-1, CD62p and Fib in lymphoma patients were significantly higher than those in control group (p < 0.01, 0.05), moreover there was positive correlation between levels of PAC-1 and Fib (r = 0.549, p < 0.01). PAC-1 expression on day 0 and 3 of chemotherapy in simple group was higher than that on day 14 (p < 0.05, 0.01) and CD62p expression on day 3 of chemotherapy was higher than that on day 0, 7 and 14 (p < 0.05, 0.01). PAC-1 expression in combined group on day 14 of chemotherapy was lower than than on day 0 and 3 (p < 0.05, 0.01), and CD62p on day 14 was lower than that on day 3 of chemotherapy (p < 0.05); PAC-1 and CD62p expressions in combined group on day 3, 7 and 14 of chemotherapy were decreased than those in simple group, but Fib level was not changed significantly. It is concluded that the patients with malignant lymphoma usually accompany with platelet activation and hyperfibrinogenemia in peripheral blood. Applying dipyridamole routine dosage in chemotherapy can efficiently restrain platelet activation.
