Objective To assess the feasibility of intestitial MR lymphangiography (MRL) with subcutaneous injection of a commercially available,non-ionic,extracellular paramagnetic contrast agent,to visualize lymphatic vessels in patients with primary lymphedema.Methods Forty lower extremities in 31 patients with clinically advanced stages of primary lymphedema were examined with magnetic resonance lymphangiography.A 1 ml mixed liquor of gadobenate dimeglumine and mepivacainhydrochloride were injected subcutaneously into the dorsal aspect of both feet For MRL,a 3D fast spoiled gradient-recalled echo T1-weighted images with a fat saturation technique (T1 high resolution isotropic volume excitation,THRIVE) were performed after subcutaneous application of the contrast material To outline lymphatic vessels,source images were used to reconstruct images of MIP.The SNR and CNR of enhanced lymphatic vessels and veins were measured and calculated respectively.The significance of the differences of the data comparisons was assessed using an unpaired student t teat.Results Of the 40 lower extremities,the beaded appearance of dilated lymphatic vessels was detected in 36 lower legs (90.0%) and 17 upper legs (42.5%).The numbers of the dilated lymphatic vessels displayed in all segments of lower extremities added up to 365 and its mean diameter was (3.4 ± 0.1) mm on MRL MIP image.The average SNR and CNR were 257 ±130,207 ± 113 in the dilated lymphatic vessels and 218 ± 129,152 ± 113 in the vein respectively,which was statistically significant (SNR t = -2.649,CNR t = -3.404,P <0.01).Contrast enhancement was observed in 30/40 inguinal lymph node groups (75.0%).In 26 lower extremities (65.0%) collateral vessels with dermal back-flow areas between lymphatic vessels were seen.Conclusions As a novel tool to image the pathologically modified lymphatic vessels in patients with clinically advanced stage of primary lymphedema,magnetic resonance lymphangiography is a safe,useful technique.

China has largest number of chronic hepatitis C (CHC) patients, with complex distribution of genotypes, high proportion of refractory types and low diagnosis and treatment rate. It is necessary to explore accessible pan-genotype antiviral treatment protocols with high cure rate. Currently, the direct acting antiviral agents (DAAs) are recommended as the main treatment regimes by international guidelines for hepatitis C. Ravidasvir (RDV) is a new generation of NS5a inhibitor, which can be widely used in treatment of gene type 1, 2, 3, 4 and 6 CHC with strong antiviral activity and high resistance barrier. A number of clinical studies demonstrate that the combination of ravidavir with DAA S, such as second-generation protease inhibitor danoprevir (DNV) and nucleoside NS5b inhibitor sofosbuvir (SOF) have gained high cure rate and good safety for CHC patients. In this article, the results of related studies on ravidavir-based antiretroviral regimens in treatment of CHC are reviewed.

Objective Comparison the corrective effect of plasma exchange method and formula method for chylemia on hematology analysis.Methods A total of 10 samples without hemolysis,jaundice and lipemia were set as control group,each sample was divided into 4 parts,then 5,10,20 and 40 μl lipid emulsion was added.Each chylous samples was treated by plasma exchange method for two times,and routine blood test was reanalyzed with hematology analyzer.The comparisons before and after the exchange was made,while the test results on each exchange were analyzed.For another part,the HGB of chylous plasma was tested,the value was substituted into HGBcorrected value =HGBbefore correction-(HGBchylous plasma-HGBchylous plasma ×HCTbefore correction).Results The chylemia could lead significant increase of HGB,MCH and MCHC (P＜0.05).After plasma exchanging for two times,the three parameters returned to normal and the count of WBC,RBC and PLT decline slightly with no significance.There were no differences between plasma exchange method and formula calibration method.Conclusion Plasma exchange method and formula calibration method could significantly reduce the impact of chylemia on routine blood analysis,which facilitate the clinical work with correct analysis of routine blood test.

Objective To understand the prevalence and genotype distribution of human papillomavirus among male patients attending to venereal outpatient department and provide basic data for prevention and treatment of HPV.Methods Retrospective analysis method was used to analyze 1 074 patients from venereal outpatient department of Beijing Friendship Hospital during January to August in 2015.Swab specimen were analyzed by flow-through hybridization and gene chip to detect the type of HPV.Chi-square test was used to compare the distribution of CA and suspected patients.Results Among the 434 CA samples, the positive rate was 72.6%(315/434).The 58.1%(252/434) samples were high risk HPV positive and 14.5%(63/434) samples were low risk HPV positive.In high risk HPV infection, multiple infection accounted for 40.4%(175/434) and single infection was 17.7%(77/434), while in low risk HPV infection, single infection accounted for 12.9%(56/434).HPV-11, HPV-6, HPV-16, HPV-52, HPV-58 and HPV-51 were common.The positive rate among suspected CA patients was 36.6%(234/640) , and dominated in high risk HPV infection 25.3%( 162/640 ) .The positive rates of high risk HPV in CA patients [ 40.4%( 175/434 ) and 17.7%( 77/434 ) ] were obviously higher than that of suspected ones [12.9%(56/434) and 1.6%(7/434)], χ2 =95.956 and 9.122, both P<0.05.Conclusions Male patients from venereal outpatient department have a high prevalence of HPV, and common genotype are HPV-11, HPV-6, HPV-16, HPV-52, HPV-58 and HPV-51.The intensity of HPV screening should be strengthened in order to provide the vital basis for the prevention and treatment HPV related diseases.

Objective To compare CT perfusion changes of patients 1 month after living liver transplantation with healthy volunteers. Methods Twenty perioperative patients without complications and 25 healthy volunteers underwent dynamic multi-slice CT scan. On each targeted slice, liver was divided into 3 regions of interest (ROI) according to hepatic venous drainage, i.e. anterior segment area drained by middle hepatic veins (MHV) which was most likely congested, risk area drained by both MHV and RHV which was posterior to anterior segment, reference area drained by RHV. Perfusion parameters and relative perfusion difference were calculated.Results The relative perfusion differences of anterior segment and risk area in study group were as follows: BF 44.56±43.19 vs 25.41±27.49 ［ml/(min〖DK〗·100 g)］; BV 3.91±2.45 vs 2.15±1.86(ml/100 g); PVP 41.50±39.15 vs 22.66±23.82 ［ml/(min·100 g)］. Significant differences of RPDs of BF, BV and PVP were found in anterior segment (P<0.0001) and risk area (P＜0.01) compared with control group.Conclusion In perioperative period, there are hemodynamic differences in hepatic segments drained by RHV and MHV. BF, BV, PVP of anterior segment decreases obviously.

Objective To assess the value of CT, PET, PET/CT in diagnosis of peritoneal metastases with Meta analysis. Methods Articles of CT, PET or PET/CT on peritoneal metastases published in English or Chinese from Jan 2000 to May 2008 were collected, and histopathological and (or) surgical findings were taken as golden standards. The sensitivity, specificity, summary receiver operating characteristic (SROC) curves, area under the curve (AUC) and the heterogeneity were calculated with software of SAS 8.0, Meta-DiSc 1.4 and STATA 10.0. Results The results of Meta analysis from 11selected articals showed that PET had the highest pooled specificity [0.96, (0.91-0.98)];PET/CT had highest pooled sensitivity [0.77, (0.67-0.85)]. The AUC and Q~* of PET, PET/CT and CT was (0.92, 0.85), (0.99, 0.96), (0.91, 0.84), respectively. AUC of PET/CT was higher than that of CT (Z=2.33, P<0.05). Conclusion PET/CT is a high accuracy diagnostic tool for detecting peritoneal metastases.
