ABSTRACT
Early small hepatocellular carcinoma (SHCC) can be cured by surgery and interventional operation to improve the survival rate of paitents,so the accurate diagnosis of SHCC is of great significance.Presently,the dynamic contrast-enhanced MR scan could only obtain single arterial phase imaging by single breath hold,and it had breathing motion artifact because of the long scanning time.The early arterial transient enhancement of SHCC was easy to be misdiagnosed.The CAIPIRINHA-Dixon-TWIST-VIBE (CDT-VIBE) sequence couldobtain high-quality multiple arterial phases images and hepatic arterial dominant (HAD) images in short-time scanning.And it could not only detect small focal lesions which were difficult to find by other imaging examination,but also find the start enhanced difference between lesions which were relevant to lesions property and blood supplement.The CDT-VIBE has a high clinical value in diagnosis and treatment of SHCC.The research progresses of CDT-VIBE in diagnosis of SHCC was reviewed in this article.
ABSTRACT
<p><b>OBJECTIVE</b>To analyze the potential association between valvular strands and migraine with aura.</p><p><b>METHODS</b>During a 1-year period,transesophageal echocardiography was performed in 51 consecutive patients with migraine with aura and 75 control subjects who underwent transesophageal echocardiography for other purposes and had no history of migraine. The presence of aortic and mitral valve strands was evaluated.</p><p><b>RESULTS</b>The incidence of valvular strands was 21.5% (11/51) in migraine patients and 28.0% (21/75) in control subjects (Χ²=0.663, P=0.416). The incidence of patent foramen ovale was significantly higher in patients with migraine with aura than in control subjects (50.9% vs.29.3%) (Χ²=6.302, P=0.012). The incidence of aortic valve strands was significantly higher than that of mitral valve strands in migraine patients (Χ²=4.320,P=0.038).</p><p><b>CONCLUSION</b>Valvular strands are not associated with migraine with aura and show little clinical significance.</p>

<p><b>OBJECTIVE</b>To evaluate the efficacy and security of propranolol gel in treatment of Infantile hemangiomas.</p><p><b>METHODS</b>51 consecutive infants with hemangiomas from October 2010 to September 2011 in Department of General Surgery Fuzhou General Hospital of Nanjing Military Command were treated with propranolol hydrochloride 3% gel. Changes in hemangioma size, texture, color, tumor blood flow peak were recorded.</p><p><b>RESULTS</b>The results were evaluated using Achauer system, responses of IHs to propranolol were considered scale I (poor) in 4 patient (17.24%), scale II (moderate) in 18 patients (24.14%), scale III (good) in 22 patients (44.83%) and scale IV (excellent) in 7 patients (13.79%). The response of superficial hemangiomas was significantly better than other hemangiomas (P < 0.05), and no significant differences in response among different primary sites (P > 0.05).</p><p><b>CONCLUSIONS</b>Topical use of propranolol hydrochloride 3% gel is an effective option for superficial hemangiomas.</p>

Objective To compare the effect of transthoracic contrast echocardiography (cTTE) with transesophageal contrast echocardiography (cTEE) for detecting right to left shunt (RLS) in patients with patent foramen ovale (PFO). Methods The prospective study was conducted in 29 consecutive patients with PFO who suffered from cryptogenic stroke and/or migraine. Contrast echocardiography was performed in all 29 patients. The cTTE was performed using transducer with second harmonic imaging modality (transmitting frequency 1.7 MHz, receiving frequency 3.4 MHz). The cTEE was performed using transducer with frequency 7 MHz. Ten milliliter saline solution of contrast were rapidly administrated through an antecubital vein. According to whether microbubble (MB) appearing in left atrium after complete opaciifcation of right atrium within the ifrst 3 circles, the results were classiifed by a four-level semi-quantitative categorization:Level 1 (no PFO-RSL), no MB in left atrium; Level 2 (small PFO-RSL) 1-10 MBs; Level 3 (medium PFO-RSL) 10-30 MBs;Level 4 (large PFO-RSL)>30 MBs. Results The total detection rate of PFO-RSL was signiifcant different between cTTE and cTEE (86.2%vs 55.2%,χ2=5.711, P=0.017). In cTTE there were 4 cases at level 1, 1 case at level 2, 5 cases at level 3 and 19 cases at level 4. In cTEE there were 13 cases at leverl 1, 2 cases at level 2, 6 cases at level 3 and 7 cases at level 4. The comparison of semi-quantitative grading derived from cTTE and cTEE was also signiifcant different (Wilcoxon signed ranks test showed Z=-3.789, P=0.000). Conclusions The efifciency in detection of PFO-RLS with cTTE was better than with cTEE. Compared with cTEE, cTTE was easier in practice and brought less discomfort and complications to patients.
