Objective To study the expressions of casein kinase 2α(Ck2α),β-catenin, survivin in ovarian cancer tissue and analyze the relationships between them, and to explore the clinical application value. Methods Immunohistochemistry staining was used to detect the expressions of Ck2α,β-catenin and survivin in 8 cases of simple ovarian cysts tissue,8 cases of ovarian benign tumor tissue and 29 cases of ovarian cancer tissue;the correlations of the expressions of Ck2α,β-catenin,survivin in ovarian cancer tissue and their associations with the clinicopathologic characteristics were analyzed.Results The expression levels of Ck2α,β-catenin and survivin in ovarian cancer tissue were significantly higher than those in simple ovarian cysts tissue and ovarian benign tumor tissue(P<0.05);the Ck2αexpression level in ovarian cancer tissue was positively corelated with the expression levels ofβ-catenin and survivin(r=0.438,r=0.479,P<0.05);the expression levels of Ck2α,β-catenin and survivin in low-medium differentiation group were significantly higher than those in high differentiation group (P<0.05);the expression levels of Ck2α,β-catenin and survivin in stagesⅡandⅢ group were significantly higher than those in stage Ⅰ group(P<0.05).Conclusion The protein expression levels of Ck2α,β-catenin and survivin are increased in ovarian cancer tissue, and three are positive corelations between them;Ck2α,β-catenin and survivin may play an important role in the occurrence and development of ovarian cancer;the combined detection of them has important clinical value.

The chemical constituents of Safflower injection were isolated and purified by polyamide, silica gel, Sephadex LH-20, ODS column chromatographies and preparative HPLC. As a result, sixteen compounds have been isolated. Based on the spectral data analysis, their structures were elucidated as scutellarin (1), kaempferol-3-O-β-rutinoside(2), hydroxysafflor yellow A(3), rutin (4), coumalic acid(5), adenosine(6), syringoside(7), (3E)-4-(4'-hydroxyphenyl)-3-buten-2-one(8), (8Z)-decaene-4, 6-diyne-1-Oβ-D-glucopyranoside(9), 4-hydroxybenzaldehyde (10), (2E, 8E) -tetradecadiene-4, 6-diyne-1, 12, 14-triol-1-O-β-D-glucopyranoside (11), kaem-pferol-3-O-β-sophorose (12), uridine (13), roseoside (14), cinnamic acid (15), and kaempferol (16). Compounds 1,2,7,9,11 and 12 were isolated from the Safflower injection for the first time. The anti-platelet aggregation activities of the isolated compounds were assayed. The results indicated all tested compounds exhibited potent activity except for 5, while 2, 3, 9 and 12 showed strong activity against platelet aggregation.

OBJECTIVETo investigate the status of vaccination against hepatitis B among postgraduate students of medical institutions of higher education in Guangzhou.

METHODSHBsAg and anti-HBs in the serum samples from 1139 postgraduate students were detected by ELISA. Data on hepatitis B vaccine inoculation were investigated by using a questionnaire. Statistical analyses were performed by using SAS software.

RESULTSThe HBsAg positive rate among the 1139 postgraduate students was 2.90 percent. The HBsAg positive rates in hepatitis B vaccine inoculated (1.15 percent) and non- inoculated (21.69 percent) postgraduate students were significantly different (x2=119.11, P<0.0001). The positive rates of HBsAb between the two groups were also significantly different (x2=62.05, P<0.0001). Among the hepatitis B vaccine inoculated students, 17.31 percent were negative for HBsAb. The positive rate of HBsAb among those inoculated the vaccine within the past 3 years was higher than that among those inoculated the vaccine earlier (0-3 years vs. 4-6 year, P=0.0089) (0-3 years vs. 7-9 years, P=0.0172) (0-3 years vs. >9 years, P=0.0474). The positive rate of HBsAb among the students who received hepatitis B vaccine booster dose was higher than that of the students who did not receive any booster dose (P=0.0093).

CONCLUSIONWith the increase of ages, the effect of vaccination for hepatitis B decreased. Male populations may be more susceptible to hepatitis B virus than female. It is necessary to monitor HBsAb levels for those who were inoculated with HBV vaccine more than 3 years ago to give booster dose in time to prevent HBV infection.

OBJECTIVETo investigate the immune effects of three different programs for revaccination among adults of non- and hypo-responders to recombinant Hepatitis B vaccine.

METHODSThose who were once immunized with recombinant Hepatitis B vaccine more than one standard schedule (0, 1, and 6 months) in two years and negative for Hepatitis B markers were randomly given three-different projects for revaccination. 34 adults of A group were given GM-CSF 300 microg by subcutaneous injection for the first day, then 10 microg each time by intramuscular route for routine immune method. 33 adults of B group were given Hepatitis B vaccine 20 microg each time. 33 adults of C group were given Hepatitis B vaccine 10 microg each time. The blood samples were collected before the first injection and in 1, 2 and 8 months following the first injection to test Anti-HBs.

RESULTSAt T1, the anti-HBs positive conversion rate of group A, B and C was 26.47%, 48.48% and 18.18% respectively (chi-2 = 7.20, P = 0.027). At T8, the anti-HBs positive conversion rate of group A (64.71%) and group B (75.76%) were higher than group C (39.39%), and there was significant difference (chi-2 = 9.07, P = 0.011). At T1, the anti-HBs level of group B (417.00 +/- 69.36) was higher than that of group A (203.74 +/- 79.56). At T2, the anti-HBs level of group B (458.17 +/- 64.09) was higher than that of group C (257.86 +/- 76.60). At T8, the anti-HBs level of group A (501.48 +/- 70.00) and group B (532.73 +/- 68.82) were higher than those of group C (256.12 +/- 75.39) (t =4.27, P = 0.0173).

CONCLUSIONSchemes of augmentation doses of Hepatitis B vaccine and being combined with GM-CSF should be in effect for non- and hypo-responders to Hepatitis B vaccine.
