Objective To evaluate the value of virtual navigation assisted 3-D contrast-enhanced ultrasound (VNA-3D-CEUS) in depicting ablative area and ablative margin after hepatocellular carcinoma radiofrequency ablation. Methods Sixty-one lesions in 51 patients were evaluated ablative area and ablative margin using VNA-3D-CEUS. The results were divided into three groups: (A) tumor was completely ablated and 5 mm ablative margin was achieved; (B) tumor was completely ablated but 5 mm ablative margin was not achieved; (C) tumor was not completely ablated. The technical successful rate of VNA-3D-CEUS,as well as the coincidence rate of complete ablation with contrast-enhanced MRI,was evaluated. The relation between local tumor progression and ablative margin was observed through follow-up. Results The technical successful rate of VNA-3D-CEUS was 78.7％ (48/61). Coincidence rate of complete ablation with contrast-enhanced MRI was 100％ (40/40). The local tumor progressions of group A and group B were 0/26 and 2/13. There was significant difference between A and B group( P =0.032). Significant correlation between local tumor progression and ablative margin was found ( r =- 1. 000, P ＜0. 001 ). Conclusions VNA-3D-CEUS could be a new method in accurately evaluating the ablative area and ablative margin after hepatocellular carcinoma ablation.

Objective To evaluate virtual navigation assisted contrast-enhanced ultrasound(VN-CEUS) by comparing VN-CEUS with routine CEUS in detecting focal liver lesion(FLL) invisible in B-mode ultrasound(BUS).Methods Forty-seven FLLs invisible in BUS were identified by CT/MR,and received VN-CEUS and routine CEUS respectively.Results The detection rate of VN-CEUS and routine CEUS were 78.7%(37/47) and 36.2%(17/47),the former was much higher than the later (P<0.01).In all the cases,fusion of CT/MR with ultrasound was achieved successfully and average time for image fusion was 5 min.compared with routine CEUS,VN-CEUS could more easily find FLLs shadowed by lung or ribs,FLLs in inhomogeneous liver background,and FLLs with brief or inapparent abnormal enhancement.ConclusionsVN-CEUS can greatly improve the detection rate of FLL that was invisible in BUS.

Objective To investigate the value of intra-cavitary contrast enhanced ultrasound(CEUS)in the location of drainage tubes which were unclear in conventional ultrasonography. Methods The locations of 32 drainage tubes in 26 patients were unclear in conventional ultrasonography. The diluted ultrasound contrast agent (SonoVue) was injected through the tubes. CEUS was used to evaluate the visualizations of the inner tubular portions and the distal ends. Whether the drainage tubes were in situ or not was also judged. The time-consumption of detection was counted. Results The percentages of the visualization of inner tubular portions and the distal ends in conventional ultrasonography were 52.25%(18/32) and 0,respectively. However,the percentages of visualization in CEUS were 100% and 93.75%(30/32), respectively. The difference were significant when compared conventional ultrasonography with CEUS ( P＜0.001 ). CEUS detected that three drainage tubes weren't in situ. And the median of timeconsumption of CEUS was just 4. 5 seconds (range: 1-77 seconds). Conclusions Intra-cavitary CEUS is a sensitive and high efficient technique in the visualization of drainage tube which may complement the insufficiency of conventional ultrasonography. It could be used as the first choice in the location of drainage tube.

Patient-centered questionnaires, as widely used tools for the diagnosis of erectile dysfunction (ED) and the assessment of ED treatment efficacy, are increasing in number and kinds. This review focuses on a few effective and most commonly used ED-related questionnaires, including the International Index of Erectile Function (IIEF), Sexual Health Inventory for Men (SHIM), Erectile Function Domain of the IIEF (IIEF-EF), Erection Hardness Grading Scale (EHGS), Self-Esteem and Relationship Questionnaire (SEAR), Erection Dysfunction Inventory of Treatment Satisfaction (EDITS), Quality of Erection Questionnaire (QEQ), Treatment Satisfaction Scale (TSS), Psychological and Interpersonal Relationship Scales (PAIRS), and Sexual Experience Questionnaire (SEX-Q). The objectives, contents and characteristics of these questionnaires are explained and discussed.

Penile erection hardness is one of the key factors for successful sexual intercourse, as well as an important index in the diagnosis and treatment of erectile dysfunction (ED). This article gives an overview on the component and impact factors of erection hardness, summarizes some commonly used evaluation methods, including those for objective indexes, such as Rigiscan, axial buckling test and color Doppler ultrasonography, and those for subjective indexes of ED patients, such as IIEF, the Erectile Function Domain of IIEF (IIEF-EF), and Erection Hardness Score (EHS), and discusses the characteristics of these methods.

This retrospective analysis compared standard regimen of doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) with the dose-dense ABVD regimen (ABVD-21) in terms of efficacy and toxicity. Patients who had early-stage unfavorable or advanced Hodgkin's lymphoma (HL) according to German Hodgkin Study Group criteria from March 1999 to February 2011 were analyzed for treatment response, long-term survival and hematological toxicity. There were 85 patients in the ABVD-21 group and 118 patients in the ABVD group respectively. The complete remission rates after completion of treatment were 92.9% and 90.7% for ABVD-21 and ABVD, respectively. During a median follow-up period of 62 months, no significant difference was found in projected 10-year progression-free survival (PFS) and overall survival (OS) rates (84.7% and 94.1% respectively for ABVD-21; 81.4% and 91.5% for ABVD). Subgroup analyses showed that ABVD-21 was significantly better than ABVD for patients with IPS≥3 in terms of PFS and OS rates. Grade 3 to 4 leukopenia (51.8% vs. 28.8%, P=0.001) and neutropenia (57.6% vs. 39.0%, P=0.009) were more common with ABVD-21. We were led to conclude that dose-dense ABVD did not result in better tumor control and overall survival than did ABVD for early-stage unfavorable HL. However, patients at high risk, for example, with IPS≥3, may benefit from dose-dense ABVD.

AIM To observe the effects of Taxilli Herba from six different hosts (Morus alba L.,Salix babylonica L.,Camellia oleifera Abel.,Castanea mollissima B1.,Liquidambar formosana Hance and Nerium indicum Mill.) on lowering blood pressure of spontaneously hypertensive rats (SHR).METHODS SHR were randomly divided into 14 groups,captopril positive group (20 mg/kg),model group,and Taxilli Herba groups of 6 different hosts,and each Taxilli Herba group was further divided into high-dose group (5.9 g/kg) and low-dose group (1.48 g/kg);WKY,in addition,was the blank control.And the 20-day consective correspondence medication was applied to the groups,each with eight rats.The caudal arterial systolic blood pressure (SBP) was measured by tail-cuff method before the administration,and on the 10th day and 20th day of the administration.Anaesthesia was performed at the blood collection 12 h after the last administration;and thus final serum contents of nitric oxide (NO) and changes of superoxide dismutase (SOD) activity,plasmatic contents of angiotensin Ⅱ (Ang Ⅱ) and endothelin-1 (ET-1) were determined.RESULTS From the data before and after administration,an SBP drop among all SHR groups was observed on the 10th day of administration,among which the blood pressure lowering effect by high-dose Taxilli Herba from Morus alba L.was very obvious (P ＜ 0.01);remarkable SBP decrease on the 20th day of administration induced by Taxilli Herba from Salix babylonica L,Liquidambarformosana Hance and Camellia oleifera Abel,and high-dose Taxilli Herba from Morus alba L,low-dose Taxilli Herba from Castanea mollissima B1 were detected (P ＜ 0.01).No significant SBP variation was available between the model group and Taxilli Herba groups after10-day administration;all the Taxilli Herba groups exhibited obvious effect in lowering SBP except Taxilli Herba from Nerium indicum Mill,low-dose Taxilli Herba from Morus alba L.and high-dose Taxilli Herba from Castanea mollissimaBl.after 20-day administration,compared to the model group (P ＜ 0.05).Highdose Taxilli Herba from Morus alba L.and Salix babylonica L significantly decreased plasmatic Ang Ⅱ and ET-1 contents of SHR groups in comparison with the model group (P ＜0.01).High-dose Taxilli Herba from Morus alba L.,Salix babylonica L.and Liquidambarformosana Hance significantly increased serum NO release and superoxide dismutase (SOD) activity (P ＜ 0.01).CONCLUSION Taxilli Herba from the five different hosts,except Nerium indicum Mill,can lower blood pressure,and there exists an effect difference due to the host variation.

Infant hemangioma, the most common benign tumor in children, is characterized by rapid proliferation, followed by slower spontaneous involution. However, some patients with facial segmental hemangioma are associated with PHACE syndrome. PHACE syndrome is characterized by vascular nerve and vascular cutaneous lesions of multiple systemic systems, often resulting in structural and functional impairments. Recent studies have demonstrated that the possible pathogeneses of PHACE syndrome mainly include hypoxia, abnormality of mesodermal vascular endothelial cells, genetic abnormality, and abnormality of interstitial mesenchymal stem cells. The current medications for hemangioma with PHACE syndrome include beta blockers, glucocorticoids, and mTOR inhibitors. This review article mainly describes the pathogenesis, diagnoses and treatments of PHACE syndrome, in order to provide directions for diagnosis and treatment of this disorder.
