Objective To analyze the characteristics and clinical value of time intensity curve (TIC) of contrast-enhanced ultrasound (CEUS) in recurrent small hepatocellular carcinoma (RSHCC) and primary small hepatocellular carrcinoma (PSHCC). Methods Sixty-five cases of RSHCC (all lesions ≤3 cm) were devided into group B1 with 42 cases of RSHCC (≤2 years ) , and group B2 with 23 cases of RSHCC ( > 2 yeras ) and group A invloved 49 cases of PSHCC (all lesions ≤3 cm). Enhancement patterns in arterial, portal and delayed phase were evaluated respectively in three groups through CEUS and analytic software Sonoliver was applied to obtain quantitative features of CEUS in the region of interest. Receiver operating characteristic (ROC) was drawn and the area under curve (AUC) was calculated. Results CEUS showed hyper-enhancement difference in arte-rial phase in group B2 (72.4%) and group A (94.8%)(P′ = 0.008) showed statistical significance, but no sig-nificance was found in enhanced iso in portal phase (P = 0.078). Hypo-enhancement in the delayed phase in group B2 (75.9%), group A (96.6%) and group B1 (95.3%) (P′ = 0.003, P′ = 0.005). TIC showed HT difference (half time of descending) in B2 group, A group and B1 group (P′ = 0.007, P′ = 0.013) indicated statistical significance but RT, TTP, MTT(P = 0.319,P = 0.104, P = 0.461) showed no difference. AUC was 0.841 (half time of descending). Conclusions Enhancement patterns of CEUS (RSHCC) are related to recur-rent time . En hancement patterns of RSHCC (> 2 years ) is not typical so CEUS should be combined with quanti-tative analysis of TIC to provide reference for its treatment and prognosis.

Objective To determine the expressions of miR-200a, miR-141, miR-205 and miR-34a in epithelial ovarian cancer (EOC) samples and to explore their clinical significance. Methods According to FIGO staging, 44 EOC pa?tients were divided into two groups:early FIGO stage (stageⅠ-Ⅱ, n=15) and late FIGO stage (stageⅢ-Ⅳ, n=29). Expres?sions of 4 miRNAs were detected by real time quantitative PCR, and were compared between two groups. The correlation of 4 miRNAs was calculated. EOC patients were divided into high miRNA expression group and low expression group according to the median value of miRNAs expression. Kaplan-Meier survival analysis and Cox multivariate analysis were used to com?pare the age, FIGO state, tumor residual after operation and post-operative chemotherapy of ovarian cancer between two groups. Results The expression of miR-141 was elevated in stagesⅢandⅣcompared with that of stagesⅠand Ⅱ(P=0.036). There was a positive correlation between expression of miR-141, miR-200a and miR-205, but a negative correlation with miR-34a (P<0.05). There was a positive correlation between miR-200a and miR-205 (P<0.05). Lower miR-200a ex?pression was associated with shorter progress free survival in ovarian cancer analyzed by log-rank test ( P=0.035). The sur?vival rate was significantly higher in FIGO stages ⅠandⅡthan that of FIGO stagesⅢandⅣ(P<0.05). Cox regression analysis revealed that miR-200a, FIGO stage and age were influential factors of overall survival time and progress-free sur?vival time of ovarian cancer, while miR-141, miR-205, miR-34a and tumor residual after operation and post-operative che?motherapy were not influential factors. Conclusion The expression of miR-200a is closely correlated with the progress and prognosis of ovarian cancer and may be used as an independent indicator for ovarian cancer prognosis.

AIM: To study the expression of Survivin and its relationship to prognosis in human hepatocellular carcinoma(HCC).METHODS: The expression of Survivin protein in 83 cases of HCC and their neighboring noncancerous tissues was detected by immunohistochemistry. The expression of Survivin mRNA in 11 cases of HCC and their neighboring noncancerous tissues was detected by semi-quantitative RT-PCR. RESULTS: Survivin protein expression was detected in 53 of 83 (63.9%) HCC tissues and 21 of 53 (39.6%) corresponding noncancerous tissues. 22 of 53 Survivin-positive HCCs (41.5%) showed punctate nuclear staining in HCC cells, 24 of 53 Survivin-positive HCCs (45.3%) showed cytoplasmic staining in HCC cells and the remaining 7 showed both nuclear and cytoplasmic staining. The positive rates of nuclear Survivin expression in cases of envelope invasion or tumor metastasis were significantly higher than those in cases without envelope invasion or tumor metastasis (P
