Objective To evaluate the value of differential diagnosis on congenital biliary atresia(BA) and infantile hepatitis syndrome(IHS) by technetium-99m-diethyl-iminodiacetic acid(99Tcm-EHIDA)hepatobiliary scintigraphy with phenobarbitol sodium.Methods Fifty-eight infants with persistent jaundice were taken phenobarbitol sodium[5 mg/(kg?d)] ,bid ?7 d).Those who had not bowel and gallbladders radioactivity within 24 hours were diagnosed as the diagnostic criterion of BA.Those with bowel and gallbladders radioactivity within 24 hours were diagnosed as the diagnostic criterion of IHS,who then received 99Tcm-EHIDA hepatobiliary scintigraphy with single photon emission computed tomography(SPECT) instrument.The results of all children were analyzed and compared with pathology and clinical follow up results.Results 99Tcm-EHIDA hepatobiliary scintigraphy correctly diagnosed 24 infants with last diagnosis BA and 29 infants with last diagnosis IHS,5 neonates false positive in all 34 IHS patients.The sensitivity in the diagnosis of BA was 100%,the specificity and accuracy were 85.3% and 91.4%,restectively.The sensitivity was 85.3% in the diagnosis of IHS;the specificity and accuracy were 100% and 91.4%,respectively.Conclusions 99Tcm-EHIDA hepatobiliary scintigraphy with phenobarbitol sodium can accurately differentiate BA and HIS at early stage.

Objective To evaluate the effect of myocardial viability on left ventricular function after elective revascularization in patients with myocardial infarction by 99Tcm-MIBI and 18F-FDG dual-isotope simultaneous acquisition (DISA) myocardial perfusion-metabolic imaging. Methods Ninety-one patients clinically confirmed of myocardial infarction underwent DISA imaging. Based on the results of echocardiography, the patients were divided into heart failure group (group A) and normal cardiac function group (group B). After PCI, left ventricular function was measured by echocardiography in 1, 3 and 6 months. The t-test and χ2-test were used to compare the difference between the two groups using SPSS 13.0. Results The average number of diseased segments by myocardial perfusion imaging was 9.8±3.5 and 5.4±2.6 in groups A and B, respectively (t=6.87, P<0.01). The average number of diseased segments by myocardial metabolic imaging was 7.5±3.4 and 4.6±2.8 in groups A and B, respectively (t=4.46, P<0.01). There were 173 segments with viable myocardium (173/458: 37.8%) in group A and 188 segments with viable myocardium (188/307: 61.2%) in group B (χ2=40.61, P<0.001). The summed perfusion score (SPS), summed metabolism score (SMS) and summed difference score (SDS=SMS-SPS) were 28.43±11.86 vs 21.36±9.54, 20.17±8.52 vs 15.19±5.74 and 0.39±3.17 vs -12.72±4.55, respectively in groups A and B (t=3.15, P<0.01; t=3.32, P<0.01; t=15.59, P<0.01). The mean change of LVEF (ΔLVEF) and the mean change of left ventricular end-diastole dimension (ΔLVEDd) of the patients with more than 4 viable myocardial segments in group A were significantly more than those in group B( (12.81±2.62)% vs (5.90±1.91)%, t=16.33, P<0.001; (-13.13±4.20) mm vs (-7.75±2.31) mm, t=6.86, P<0.001). However, the ΔLVEF and ΔLVEDd of the patients with less than 4 viable myocardial segments in group A were significantly less than those in group B (t=3.25, P<0.01; t=4.92, P<0.001). Conclusion The amount of viable myocardium in infarct myocardium is an important factor for left ventricular function recovery after elective revascularization.

Objective Circulating tumor cells (CTCs) have potential value in the clinical application of various tumors. This study was to investigate the role of CTCs and their chemokine receptor CCR9 in the invasion and metastasis of non-small cell lung cancer (NSCLC). Methods From May 2018 to June 2019, a total of 62 patients with NSCLC in the clinical oncology center of The People's Hospital of Guangxi Zhuang Autonomous Region were enrolled in this study. The CanpatrolTM CTC technique was used to detected the expressions of CTCs and CCR9 in CTCs in peripheral blood of patients. Furthermore, the relationships between expression levels of CTCs, CCR9 and clinical, pathological characteristics of NSCLC patients were analyzed. Results CTCs were detected in 56 of 62 (90.3%) NSCLC patients. CTCs counts were associated with TNM stage, lymph node metastasis and distant metastasis of NSCLC (P<0.05). In the analysis of clinical correlation between CTC subtypes and NSCLC, epithelial CTCs counts were related to TNM stage and distant metastasis of NSCLC (r=0.296 and r=0.273, P<0.05). Additionally, counts of mixed type CTCs were also correlative with NSCLC tumor metastasis (r =0.253, P =0.047). Finally, we found that the positive rate of CCR9 in mixed type CTCs was associated with distant metastasis of NSCLC (r=0.353, P=0.038). Conclusion CTCs counts and subtypes were correlated with TNM stage and metastasis of NSCLC. The expression level of CCR9 on CTC was expected to be a biomarker to evaluate the risk of tumor metastasis in NSCLC.
