RESUMO
Objective To discuss the correlation between nature of carotid plaque by dual-source CT examination and serum levels of hypersensitive C-reactive protein (hs-CRP),lipoprotein a (LPa) and homocysteine (Hcy),and provide a better theoretical basis for the prevention and treatment of ischemic cerebrovascular disease.Methods Fifty carotid plaque patients with ischemic cerebrovascular disease symptoms (group A),50 carotid plaque patients without ischemic cerebrovascular disease symptoms (group B)and 50 healthy people (group C) were selected.All objects were detected the carotid plaque by dual-source CT,and the serum levels of hs-CRP,LPa and Hcy were detected by the automatic biochemical analyzer.The correlation between the nature of carotid plaque by dual-source CT examination and the serum levels of hs-CRP,LPa and Hcy was analyzed.Results The total number of carotid plaque,number of unstable plaque and number of stable plaque in group A were 357,220 and 137 pieces,respectively.Those in group B were 200,13 and 187 pieces,respectively.There were statistical differences between group A and group B (P ＜ 0.01).Patients in group A and group B were mainly with unstable plaque and stable plaque,respectively.Healthy people in group C were without carotid plaque.The serum levels of hs-CRP,LPa and Hcy in group A were (36.74 ± 13.22) mg/L,(563.15 ± 178.69) mg/L and (40.15 ± 12.31) μ mol/L,respectively.These in group B were (12.36 ± 4.35) mg/L,(393.56 ± 86.45) mg/L and (29.45 ± 7.63) μ mol/L,respectively.These in group C were (3.26 ± 1.26) mg/L,(220.17 ± 35.24) mg/L and (14.32 ± 2.44) μ mol/L,respectively.The serum levels of hs-CRP,LPa and Hcy in group A were significantly higher than those in group B and group C,and those in group B were significantly higher than those in group C,there were statistical differences (P ＜ 0.05).The serum levels of hs-CRP,LPa and Hcy were positive correlation with the number of carotid unstable plaque,the correlation coefficients between the serum levels of hs-CRP,LPa and Hcy and the number of carotid unstable plaque in group A were 0.469,0.398 and 0.363 (P ＜ 0.05),respectively,in group B were 0.276,0.145 and 0.127(P ＜ 0.05),respectively.The correlation coefficients between group A and group B were significantly different (P ＜ 0.05).Conclusions The combination of dual-source CT examination and the serum levels of hs-CRP,LPa and Hcy is more beneficial to judge the stability of plaque,and it can help predict the nature of the carotid plaque.This view is important clinically for the prevention and treatment of the occurrence and the development of the ischemic cerebrovascular disease.

RESUMO
Objective To investigate the value of combined detection of serum tumor biomarkers including alpha-fetoprotein (AFP),tumor specific growth factor (TSGF),golgi protein 73 (GP73) and osteopontin (OPN) in diagnosis of primmy hepatic carcinoma.Methods AFP,TSGF and GP73 levels were measured by electro-chemiluminescence immunoassay,and OPN levels by enzyme-linked immunosorbent assay (ELISA) in 122 cases of primary hepatic carcinoma,50 cases of liver benign lesions and 50 cases of healthy control.The biological parameters and the levels of AFP,TSGF,GP73 and OPN were studied.Results The serum levels of AFP,TSGF,GP73 and OPN in primary hepatic carcinoma were higher than those in the liver benign disease group and the normal control group (all P ＜ 0.01).Sex and age of the patients at diagnosis showed no significant association with the levels of the four serum tumor biomarkers in the primary hepatic carcinoma groups (all P ＞ 0.05).But the tumor size,amount,tumor stage,metastasis and recurrence showed significant association with the levels of those in the primary hepatic carcinoma groups (all P ＜ 0.05).The sensitivity,specificity and veracity of serum AFP,TSGF,GP73 and OPN as individual diagnostic marker was only 57.38 ％,68.85 ％,70.49 ％ and 69.67 ％,respectively.The sensitivity of combined detection of AFP and TSGF was 80.33 ％,and that of combined detection of AFP,TSGF and GP73 was 85.25 ％.While,the sensitivity of the four serum tumor markers in combination was 98.36 ％,the accuracy was 95.65 ％.The sensitivity and accuracy of combined detection with the four serum tumor markers were significantly higher than those of the individual markers and other combination detection methods (all P ＜ 0.05).Conclusions Serum markers of AFP,TSGF,GP73 and OPN can serve as a means for diagnosis of primary hepatic carcinoma.Combined detection of the four serum tumor biomarkers can improve the sensitivity,accuracy and the negative predictive value,which is benefit to early diagnosis and interference.

Results The CA153, CEA levels of nipple discharge in breast cancer were significantly higher than the control group(CA153:t =28.949,33.844;CEA:t = 19.773,16.623, all P ＜ 0.01). The positive rate of CA153, CEA in nipple discharge were significantly higher than in the serum (P ＜ 0.05). Conclusion The positive rate of CA153, CEA in nipple discharge were significantly higher than in the serum. The detection of CA153 ,CEA had important value in the early diagnosis of breast cancer.
RESUMO
Objective To explore the clinical value of combined detection of CA15-3, TSGF, OPN and CA125 in the diagnosis and treatment of breast cancer. Methods The serum specimens from 187 patients with breast cancer (cancer group) were collected, tumor markers CA15-3 and CA125 were detected with electrochemiluminescence method, TSGF was detected with chemocolorimetry, and OPN was detected with enzyme-linked immunosorbent assay. Compared with 50 cases of patients with benign breast disease (control group), The relationship between these marker and clinical stage, recurrence and metastasis of breast cancer were analyzed. Results The serum levels of CA15-3, CA125, TSGF and OPN in cancer group were significantly higher than those in control group (P ＜0.05). Four markers in high clinical stage(Ⅲ and Ⅳ stage)[(83.21±28.67), (89.13±32.34), (278.66±137.23) U/ml and (97.4±11.7) ng/ml, respectively] were higher than those in low stage( Ⅰ and Ⅱ stage) [(60.03±19.35), (58.21±17.56), (155.79±113.11) U/ml and (77.5±10.81) ng/ml,respectively] (P ＜0.05), and those in lymphnode metastasis patients and in recurrence patients were significantly higher than those in corresponding groups (P ＜0.05). The sensitivity and specificity of the combined detection of four tumor markers were 96.3 % (180/187) and 80.0 % (40/50), respectively. The average time of combined detection of serum tumor markers was 2 months ahead of the mammographic features in the recurrence patients with breast cancer. Conclusion The dynamic combined detection of CA15-3, TSGF, OPN and CA125 are better markers for monitoring recurrence and metastasis of breast cancer,which are benefit to early diagnosis and interference.
