Objective To explore the value of stress dual-phase (early and delayed phases)18 FFDG myocardial PET/CT in detection of myocardial ischemia.Methods Ten swine were prepared as ischemic models and underwent 3 imaging procedures:pre-model stress (8 swine),post-model rest (8 swine)and post-model stress dual-phase imaging (10 swine).To perform stress dual-phase imaging,the tested subjects were fasted for more than 12 h and underwent early-phase PET imaging at 50 min after the intravenous injection of 18F-FDG (5 MBq/kg) for 10 mins,and followed by a dobutamine stress test,and then delayed-phase PET imaging at 50 min after the stress test for another 10 mins.The post-model rest dual-phase imaging was performed in almost the same way except that there was no dobutamine-loading.18F-FDG uptake image was qualitatively analyzed and classified into 4 levels:1 =no uptake,2 =diffuse uptake,3 =focal uptake,4=focal on diffuse uptake.Level 1 or 2 was considered as normal.If the focal uptake (level 3 or 4)was found on anterior wall or septum,ischemia was diagnosed.x2 test was used to determine the difference of the rate of ischemic myocardium between the two phases.18F-FDG uptake ratio of the anterior wall to posterior wall (K) of the left ventricle was calculated (K1 for early phase and K2 for delayed phase).Wilcoxon rank sum test was applied to determine the difference between K1 and K2.Results CAG showed LAD stenosis ＞70％ in all swine.In pre-model stress dual-phase imaging,no ischemia was detected at two phases (8/8 for level 1 or 2,0 for level 3 or 4).There was no significant difference between K1 and K2(1.08±0.10,1.11 ±0.10; Z =-1.48,P＞0.05).In post-model rest dual-phase imaging,the rate of ischemic myocardium was not significantly different between early and delayed phases (1/8,3/8 ; x2 =0.50,P＞0.05).There was no significant difference between K1 and K2(1.47±0.28,1.28±0.40; Z=-2.02,P＞0.05).In post-model stress dual-phase imaging,the rate of ischemic myocardium between the two phases was statistically different (4/10,10/10;x2=4.17,P＜0.05),and the difference between K1 and K2 was also significant (1.55±0.32,1.86±0.39; Z=-2.49,P＜0.05).Conclusion Stress dual-phase 18F-FDG myocardial PET/CT might be useful for the diagnosis of ischemia.

Objective To detect content of 4-hydroxy-3-methoxy benzoic acid by RP-HPLC and observe the inhibitory effect of phloroglucinol on catecholamine-O-methyl transferase (COMT). Methods This study used the principle of 3,4-dihydroxy benzoic acid transforming to 4-hydroxy-3-methoxy benzoic acid under COMT’ s catalytic action. COMT (20 μL) was extracted from mouse liver homogenate. In a reaction system,10 μL catecol (1í10-3 mol·L-1 ) and 10 μL phloroglucinol (5í10-3 , 1í10-3 and 2í10-4 mol·L-1 ,respectively) were added. Products were determined by RP-HPLC to analyze effects of 4-hydroxy-3-methoxy benzoic acid on COMT. Results Phloroglucinol had inhibitory effect on COMT activity at concentrations of 5í10-3 mol·L-1 ,1í10-3 mol·L-1 and 2 í10-4 mol ·L-1 ,with the inhibition rate being 25. 3% ,17. 6% and 8. 9% ,respectively. Conclusion Phloroglucinol has an inhibitory effect on COMT activity,which is weaker than the effect of catechol of the same concentration.

CONCLUSION: (IFN-?1b) is able to induce the apoptosis and suppress the expression of CTGF in HSC.

Objective To investigate the impact of calcification on differential diagnosis of thyroid nodule using shear wave elastography (SWE). Methods One hundred and forty-six patients with thyroid nodules were prospectively enrolled in the study. Ultrasound observations included nodule size, boundary, shape, envelope, internal echotexture, posterior acoustic enhancement, and the relationship with surrounding tissue. According to the presence of internal calciifcation, patients were divided into calciifcation group (groupⅠ) and no calciifcation group (groupⅡ). Real-time shear wave elastography (young′s modulus value) were taken in both groups. Taking surgical pathologic results as the gold standard, receiver operating characteristic (ROC) curve of SWE in diagnosis of benign and malignant thyroid nodule were drawn for two groups respectively. Results In groupⅠ, 25 cases were benign and 38 cases were malignant. The malignant incidence was 60%. Among them the rate of malignant nodules in microcalcification group was 92%(24/26). The incidence of malignant nodules in coarse calcification group was 38%(14/37). The area under the curve (AUC) of SWE in groupⅠwas 0.564. In groupⅡ, 67 cases were benign and malignant had 16 cases. Using 30.43 kPa as the diagnostic point of young′s modulus value, the sensitivity, speciifcity, accuracy and AUC were 93.2%, 81.2%, 84.8%and 0.824. Conclusion In no calciifcation group, SWE is more meaningful in the differential diagnosis of benign and malignant thyroid nodules.

Objective To discuss the therapeutic effect of transcatheter arterial embolization using hardening agent combined with oral propranolol in treating giant hemangioma at maxillofacial region in infants. Methods During the period from October 2013 to December 2014 at Imaging Center of Anhui Provincial Children's Hospital, transcatheter arterial embolization using hardening agent combined with oral propranolol was employed in a total of 27 infants with giant hemangioma at maxillofacial region. The age of the infants ranged from 2 months to 22 months (mean 5.9 months) and the body weight was 4.5-10 kg with a mean of 6.32 kg. Angiography via femoral artery was performed, which was followed by super-selective catheterization of hemangioma-feeding artery, and then pingyangmycin lipiodol emulsion was injected into the hemangiomas with subsequent injection of PVA particles to obstruct the hemangioma-feeding artery. After the embolization treatment, the patient received oral propranolol for 3-6 months. Results All the infant patients were followed up for 3-6 months. Clinical examination and ultrasonography indicated that the hemangioma was cured in 20 infants (75%) and the therapeutic result was effective in 7 infants (25%). Skin necrosis at hemangiomas site was observed in 2 infants (7.5%), which was cured after symptomatic treatment. No serious complications such as pulmonary embolism, cerebral embolism occurred, and no recurrence was observed. Conclusion For the treatment of giant hemangioma at maxillofacial region in infants, transcatheter arterial embolization using hardening agent combined with oral propranolol is minimally invasive, quickly effective and highly safe;and this treatment leaves no scar formation in most cases. Therefore, this technique is worthy of clinical application.

Objective: To investigate the prognostic factor for small side branch (SB) occlusion during coronary bifurcation intervention with the incidence rate of peri-procedural myocardial injury (PMI) in relevant patients.
Methods: A total of 925 consecutive patients who received coronary bifurcation intervention were enrolled and there were 949 SB lesions ≤ 2.0 mm conifrmed by quantitative coronary angiography (QCA). The patients were divided into 2 groups: SB occlusion group,n=85, including 86 bifurcation lesions and Non-SB occlusion group,n=840, including 863 bifurcation lesions. The clinical characteristics, QCA findings and PCI procedural conditions were studied by Multivariate logistic regression analyses to explore the independent predictors of SB occlusion and to compare the incidence rate of PMI.
Results: The total SB occlusion rate was 9.1% (86/949). SB occlusion group had the higher incidence rate of PMI (26/83, 31.3%) vs (77/821, 9.4%) and peri-operative MI mortality(6/83, 7.2%) vs (11/821, 1.3%) than Non-SB occlusion group, both P<0.001. In SB occlusion group, the diameter ratio of main vessel (MV)/SB was obviously higher than Non-SB occlusion group,P<0.001. The independent predictors of SB occlusion included in true bifurcation lesion, irregular plaque, pre-dilation of SB, TIMI lfow grade of pre-procedural SB, stenosis degrees of distal MV and bifurcation core, bifurcation angle, diameter ratio of MV/SB and the stenosis degree of SB before MV stenting.
Conclusion: Coronary bifurcation lesion patients with SB occlusion had the higher risk of PMI during the interventional procedure.
