Objective To evaluate contrast-enhanced ultrasonography (CEUS) in diagnosis of small hepatocellular carcinoma (SHCC) ( ≤ 2. 0 cm) with liver cirrhosis after contrast-enhanced CT (CECT) examination. Methods Forty five patients with liver cirrhosis received CECT and CEUS examinations before operation or needle biopsy and the diagnosis was confirmed by pathological examination.CEUS and CECT findings of 51 liver space-occupying lesions from 45 patients were retrospectively analyzed.Results Among all 51 lesions detected CEUS and CECT found 49 and 35, respectively. The typical characteristics of SHCC were "fast-in and fast-out" and "fast-in and slow-out". The sensitivity of CEUS and CECT in diagnosis of SHCC was 88. 9% (32/36) and 69. 4 % (25/36) respectively ( x2 = 3. 02, P =0. 08);the diagnostic accuracy was 84. 3 % (43/51 ) and 56. 9% (29/51 ) respectively ( x2 = 1.46, P =0. 22). Among 16 lesions missed by CECT, 12 were detected by CEUS. Conclusions CEUS and CECT show the similar diagnostic rate for typical SHCC ,however, CEUS is more sensitive for atypical lesions. With high time resolution, CEUS have advantages for follow-up study of benign liver lesions.

Objective To investigate the value of contrast enhanced ultrasonography in evaluating cystic renal mass. Methods According to the imaging diagnosing standard, 29 cystic renal mass lesions were studied with contrast enhanced ultrasonography(CEUS), unenhanced ultrasonography (US), contrast enhanced CT(CECT) and then correlated their results with final histopathological results. The data were tested by receiver operating characteristic(ROC) curve. Results The area under ROC curve of CEUS and US was 0. 721, 0. 997, respectively. There was significant difference between the 2 groups (P=0. 003). The area under ROC curve of CEUS and CECT was 0. 997, 0. 997,respectively. There was no significant difference between the 2 groups (P= 1. 000). Conclusions CEUS is better than US and similar to CECT in evaluating cystic renal mass. CEUS with the Bosniak classification is useful for evaluating cystic renal mass.

Objective The purpose of this study was to evaluate the value of contrast-enhanced ultrasound in diagnosis of renal cell carcinoma subtyping.Methods 206 cases with renal tumors were confirmed by pathology and surgery from June 2012 to June 2014,including 113 male cases and 93 female cases.The mean age was 54 years (range 23-80 years).The subtype of renal tumor included clear cell carcinoma in 147 cases,papillary cell carcinoma in 32 cases,chromophobe cell carcinoma in 27 cases.All patients were received the CEUS before operation.The enhancement patterns,degree of enhancement,the appearance of necrosis and the time-intensity curve by contrast-enhanced ultrasound were analyzed.Results Enhancement patterns of CEUS were showed by fast in and fast out in 63.9％ (94/147)cases with clear cell carcinoma,59.4％ (19/32) cases with papillary cell carcinoma,51.9％ (14/27) cases with chromophobe cell carcinoma.Statistical significant diference was shown among those subtype groups (P ＜ 0.05).Most of the clear cell carcinomas (127/147,86.4％) showed hyperenhancing.While,the papillary renal cell carcinoma (22/32,68.8％) and chromophobe cell carcinoma (15/27,55.6％) showed hypoenhancing (P ＜ 0.05).The rate of necrosis in clear renal cell carcinoma was 62.6％ (92/147),and 59.4％ (19/32) in papillary cell carcinoma.necrosis area accounted for only 18.5％ (5/27)in chromophobe cell carcinoma (P ＜ 0.05).In the time-intensity curve analysis,the initial time,the average arrival time,the time to peak and area under the curve in renal cortex was (11.06 ± 2.75) s,(23.42 ± 2.79) s,(27.47 ± 3.02) dB,(35.01 ± 2.94)dB,respectively.Significant differences in those items were found in clear cell carcinoma,which was(8.01 ± 1.89) s,(20.05 ± 3.01) s,(30.03 ± 2.98) dB,(37.64 ± 4.01) dB respectively,compared with those in cortex (P ＜ 0.05).The arrival time,time to peak,peak intensity and area under the curve in papillary cell carcinoma were (1 1.12 ± 2.43) s,(27.29 ± 3.54) s,(20.13 ± 2.67) dB,(34.67 ±3.24) dB,respectively.The curve showed the time to peak was higher and the peak intensity were lower than those of renal cortex (P ＜0.05).The arrival time,time to peak,peak intensity and area under the curve in chromophobe cell carcinoma were (11.32 ± 2.90) s,(22.21 ± 3.62) s,(22.02 ± 2.52) dB,(28.67 ± 3.65) dB,respectively.The curve demonstrated peak intensity and area under the curve were lower than those of surrounding renal cortex (P ＜ 0.05).The increase of tumor diameter after contrast-enhanced ultrasound in clear cell carcinoma was about (0.35 ± 0.11)cm and in nonclear cell carcinoma was about (0.23 ± 0.10) cm (P ＜ 0.05).Conclusion The contrast-enhanced ultrasound played an important role in diagnosis and subtype renal cell carcinoma.

Objective To explore the diagnostic value of the quantitative detection of plasma miRNA-125b and miRNA-133b in children with asthma.Methods Thirty asthmatic patients were enrolled in this study and collected the blood specimens during acute phase and stable phase respectively (AP group and SP group).Thirty allergic rhinitis children (AR group) and thirty healthy children were recruited to the control group (NC group).The levels of miRNA in different groups were detected by qRT-PCR.The performance of miRNA-125b and miRNA-133b were evaluated by receiver operating characteristic curves (ROC) and the area under the curve (AUC) (95％CI).Results The relative expression of miRNA-125b in AP group and SP group were significantly higher than A R group (t=3.913,3.120,P＜0.01),miRNA-133b.In AP group and AR group the expression of miRNA-133b were significantly higher than control group (t=4.426,4.720,P＜0.01).The detection of miRNA-125b yielded an area under the curve of ROC of 0.7989,(95 ％ CI:0.7111～ 0.8864) in discriminating asthmatic patients from healthy group.And the miRNA-133b was 0.7274 (95％CI:0.586 5～0.863 0) in discriminating asthmatic patients during the acute phase from healthy group.Conclusion The relative expression of miRNA-125b in children with asthma was significantly higher than that in AR group and NC group,miRNA-125b may prove to be a non-invasive biomarker for the auxiliary diagnosis of asthma especially when the relative expression up to 1.998.
