Objective To investigate the significance of the combined detection of several serum tumor markers with high-risk human papillomavirus (HR-HPV) in the diagnosis of cervical cancer.Methods Chemiluminescent microparticle immunoassay(CMIA) was employed to measure the levels of serum CA125,CA19-9,SCCA and CEA in peripheral blood samples collected from 249 patients with cervical cancer,30 patients with cervix intraepithelial neoplasia(CIN),and 60 healthy controls.The levels of serum CA72-4,HE4 were measured by electrochemiluminescence immunoassay(ECLI).Flow-through hybridization and gene chip technology (HybriMax) was employed to measure the HPV genotypes in all the 339 cases of women.Results Serum CA72-4 level in the cervical cancer group [3.13 (2.25,7.63) ng/mL] was significantly higher than that in the C IN group [2.37 (1.98,6.25) ng/mL] and the control group [2.69 (2.35,3.35) ng/mL] (P =0.028;P =0.003).Serum CEA level in the cervical cancer group 3.08 (2.28,4.75) ng/mL was significantly higher than that in the CIN group [1.45 (1.00,1.83) ng/mL] and the control group [2.13 (1.45,2.67) ng/mL] (P =0.000;P =0.000).Serum CA 125 level in the cervical cancer group [24.4(20.30,44.15) U/mL] was significantly higher than that in the CIN group[12.85(7.90,16.23)U/mL] and the control group[12.33 (11.26,17.11) U/mL] (P =0.000;P =0.000).Serum CA19-9 level in the cervical cancer group[27.05(18.48,38.01) U/mL] was significantly higher than that in the CIN group[13.01 (8.79,17.12) U/mL] and the control group[12.83 (10.89,17.93) U/mL] (P =0.000;P =0.000).Serum SCCA level in the cervical cancer group [1.7 (0.90,4.75) ng/mL] was significantly higher than that in CIN group [0.8 (0.60,1.10) ng/mL] and the control group [0.6 (0.50,0.70) ng/mL] (P =0.000;P =0.000).However,there was no significant difference of HE-4 among three groups (P ＞ 0.05).The HR-HPV infection rates in the cervical cancer (92.4％) and CIN patients (90.0％) were significantly higher than that in controls (15.0％)(x2 =46.875,P =0.000;x2 =165.178,P =0.000).In the cervical cancer patients,the levels of serum tumor marker was associated with Federation International of Gynecology and Obstetrics (FIGO) stage (P ＜ 0.05).ROC curves showed HR-HPV was the most sensitive in the diagnosis of cervical cancer.The sensitivity of the diagnosis of cervical cancer by serum tumor markers combined with HR-HPV(97.99％) was significantly higher than that of single marker,CA724 25.30％,CEA 20.89％,CA125 27.71％,CA199 24.90％,SCCA 52.61％,HPV 92.37％ (x2 =278.237,P =0.000;x2 =307.036,P =0.000;x2 =263.348,P =0.000;x2 =280.769,P =0.000;x2 =137.864,P =0.000;x2 =8.580,P =0.003).Conclusion Serum tumor markers combined with HR-HPV check can improve the detection rate of cervical cancer and has important clinical value.

Objective: To test applicability of the Center for Epidemiological Studies Depression Scale (CES-D) in different age groups in urban China, and to develop age norms. Methods: In this cross-sectional study, the CES-D was administrated to 16047 community participants with average age of (37.7±21.3) years (age ranged 11～100) in 21 provinces, who were as the norming sample. Criterion validity was tested in 349 psychiatric patients with average age of (32.0±12.1) years (age ranged 16～81) in 4 cities. A subsample (199 workers, 100 col-lege students, and 30 teachers in Beijing, Dongguan, and Baotou) was drawn from the national sample to provide 8 week interval test-retest reliability. Results: The Cronbach α was 0.90 for the scale, and 0.68～0.86 for its fac-tors. The 8 week interval test-retest correlation was 0.49 for the scale (P <0.01) and 0.39～0.51 for factors (P<0.01) . The result of confirmatory factor analysis supported the original 4-factor structure (RMSEA=0.057, CFI =0.976, GFI=0.948) . Patients scored higher than community sample [(21.72±13.39 ) vs.(13.24±10.33),P <0.01], and depression patients scored the highest [(27.82±14.42), P<0.01] . Age difference was signifi-cant. Age groups over 60-year-old scored higher than all the other age groups under 60-year-old (P<0.01). Con-clusion: The Chinese version of CES-D shows good refiability and validity across all ages in urban population-

Objective To investigate the clinical characteristics and the optimal time of delivery in pregnant women with severe preeclampsia complicated with ascites. Methods A retrospective study was conducted on 179 severe preeclampsia mothers and their 195 neonates,presented in the First Affiliated Hospital of Wenzhou Medical College from Jan.2003 to Dec.2005,who were divided into two groups:32 complicated with ascites(ascites group)and 147 without(non-ascites group). The general conditions,mode of delivery and complications including eclampsia,hemolysis,elevated serum level of 1iver enzymes,and low platelets(HELLP syndrome),liver failure,renal failure,heart failure,hypoproteinemia,placental abruption,postpartum hemorrhage and puerperal infection,were also analyzed.Clinical data of all infants(38 from ascites group and 157 from non-ascites group)were analyzed.The incidence and mortality rate of small for gestational age(SGA)in both group within the same gestational age group and those between different gestational age groups in the ascites group were compared. Results (1)The average gestations at admission and delivery in the ascites group were earlier than the other[admission:(32.5±2.1)weeks vs(36.1±3.5)weeks;delivery:(34.1±2.3)weeks vs(37.2±1.5)weeks,P＜0.053.The rate of systemic antenatal care in the ascites group waslowcr than that of the non-ascites group(25.0%vs 53.7%,P＜0.05).More complications werefound in the ascites group than in the non-ascites group(hypoproteinemia:100.0%vs 47.0%;liver and renal failure:31.2%vs 8.2%;HELLP syndrome:9.4%vs 2.0%;postpartum hemorrhage:18.8%vs 2.0%;all P＜0.05).(2)The incidence of SGA in the ascites group was all higher than that in the non-ascites group,however,significant differences was only found between the tWO groups at＞36 weeks(7/9 vs 30.2%,P＜20.05).The perinatal mortalily rates of SGA in the ascites group at＜32 weeks and 32～34 weeks were significantly higher than that in the non-aseites group respectively(＜32 weeks:69.2%vs 19.2%,P＜0.05;32～34 weeks:2/7 vs 0,P＜0.05).(3)The highest perinatal mortality rate and the highest incidence of SGA in the ascites group were found in the groups of＜232 weeks and＞36 weeks,respectively. Conclusions The early onset of ascites and higher rate of complications in severe preeelamptie women implies the adverse maternaI and fetal outcomes.Ascites in severe preeclampsia cases should alert the clinicians.The optimal time for delivery might be at 32～36 weeks of gestations.
