ABSTRACT

Objective To evaluate the value of ultrasound-guided core needle biopsy(US-CNB) in diagnosing malignant and benign thyroid nodule by meta-analysis.Methods A computer-based online retrieval on the accurate tests of US-CNB for diagnosing thyroid nodule was conducted in PubMed,Cochrane Library (Issue 5,2016),EMbase,CBM,CNKI,VIP,Wangfang Data databases.The retrieval time limit was from the database establishment to June 8,2016.The quality of included articles was assessed by using the quality assessment of diagnostic accuracy studies (QUADAS).The puncture success rate,diagnosis sensitivity (Sen),specificity (Spe),positive likelihood ratio (+LR),negative likelihood ratio (-LR),diagnostic odds ratio (DOR) and area under the curve (AUC) of summary receiver operating characteristic curve (SROC) were served as the outcome indicators.The included data were performed the statistical analysis by using STATA12.0 and Meta-Disc 1.4 softwares.Results A total of 29 diagnostic accuracy trials were finally included,involving 4 213 patients with 4 391 thyroid nodules.The meta-analysis results suggested that the US-CNB puncture success rate was 98.7 % [95% CI (98.3 %,99.0 %)];Sen of US-CNB for diagnosing thyroid nodule was 0.94 [95%CI(0.93,0.95)],Spe=0.98[95 %CI(0.98,0.99)],+LR=33.96[95%CI(20.31,56.78)],-LR=0.06[95%CI(0.04,0.10)],DOR=581.44[95 %CI(335.08,1 007.87)],and the AUC of SROC was 0.99.Conclusion The current evidences indicate that UG-CNB has high diagnostic accuracy in benign and malignant thyroid nodules,and is worth promotion and application in clinic.

ABSTRACT

Objective To evaluate the left ventricular and right ventricular systolic function by two‐dimensional speckle tracking echocardiography ( 2D‐STE) in patients with rheumatoid arthritis ( RA ) . Methods Fifty five patients with RA and 50 healthy subjects were received echocardiography . 2D‐STE were applied for all the subjects to obtain left ventricular global longitudinal strain ( LVGLS) and right ventricular global longitudinal strain ( RVGLS) .Tricuspid annular plane systolic excursion ( TAPSE) and the change ratio of right ventricular area ( RVACR) were measured by echocardiography . The anti‐cyclic citrullinated peptide antibodies ( anti‐CCP‐II) ,rheumatoid factor ( RF) ,C‐reactive protein ( CRP) and erythrocyte sedimentation rate ( ESR) were detected in both group . The LVGLS and RVGLS in RA group were used to conduce correlation analysis with the level of anti‐CCP‐II ,RF ,CRP , ESR and the duration of disease . Results There was a significant decrease in RVGLS and LVGLS in RA group compared with control group( P 0 .05) . The anti‐CCP‐II ,RF ,CRP and ESR in RA group increased significantly compared with control group ( P < 0 .001 ) . The result of correlation analysis showed there was no correlation between RVGLS ,LVGLS and anti‐CCP‐II ,RF ,CRP ,ESR in RA group . However ,RVGLS and LVGLS were negatively correlated with the duration of disease . Conclusions LVGLS and RVGLS in RA patients were lower than those in healthy people ,strain decreases with the extension of disease duration ,2D‐STE may be an efficacious assessment to assess left ventricular and right ventricular systolic function in patients w ith RA .

ABSTRACT

Objective To investigate the clinical value of the combined detection of Golgi protein 73 (GP73),alpha-fetoprotein variant-L3 (AFP-L3)and transforming growth factorβ1(TGFβ1)in the early diagnosis of hepatocellular carcinoma (HCC).Meth-ods 48 cases of healthy control,42 cases of hepatitis B,50 cases of posthepatitic cirrhosis and 58 cases of HCC were selected and detected GP73,AFP-L3 and TGFβ1.The detection results were compared among 4 groups.Results (1)The levels of GP73,AFP-L3 and TGFβ1 had statistical differences among 4 groups(P <0.05 );(2 )The positive rate of the 3-marker combined detection reached 96.55%,which was higher than that of the 2-marker combined detection and the single marker detection.Conclusion (1) GP73,AFP-L3 and TGFβ1 may be used as the serum indicators for the early diagnosis of HCC;(2)Compared with the traditional HCC marker AFP,AFP-L3 has relatively high sensitivity and specificity and has the important role in the differential diagnosis of benign and malignant diseases of the liver,which is considered as a better serum marker in the HCC diagnosis;(3)The 3-indicator combined detection can significantly improve the positive detection rate of HCC and has better application value.

ABSTRACT

Objective To detect the atherosclerotic progression in low density lipoprotein receptor (LDL-R) gene knock-out mouse by ultrasound biomicroscopy(UBM) technique,and to monitor the intima media thickness (IMT) and changes in plague of aortic wall.Methods 10 male LDL-R gene knock-out mice of 16 weeks age and 10 LDL-R gene knock-out mice of 24 weeks age were in the experimental group,and 10 male C57BL/6 mice of 16 and 24 weeks age were in the control group.The shapes of their aortic roots,ascending aorta,aortic arch and CCA were detected by UBM,and the IMT at aortic root view and carotid artery bifurcation were measured,then the data were compared with histopathology of the corresponding vascular segments.Results The difference between the IMT of aortic root and carotid artery bifurcation of the 16 week old LDL-R mice and the control group of the same age had no statistical significance.The difference between the IMT of carotid artery bifurcation of the 24-week-old LDL R mice and the control group of the same age had no statistical significance.The IMT of aortic root thickened compared with control group of the same age(P <0.01).Conclusions The UBM technique can be used to detect the atherosclerotic progression in LDL-R gene knock-out mouse.
