Objective To explore imaging manifestations of hepatic epithelioid hemangioendothelioma (HEH). Methods CT and MR images in 14 patients with HEH proven by histopathology were retrospectively analyzed. Plain and two-phase contrast-enhanced CT scan were performed in 5 cases, non-contrast and multiphase contrast-enhanced MR scan were performed in 7 cases, CT and MRI were both performed in 2 cases. Characteristics of CT and MR T2WI images were classified and analyzed. All lesions were classified into three types:multiple, diffuse and solitary form. Results (1) Multiple form of HEH:228 lesions were found in 11 patients, including 178 lesions on MRI and 50 lesions on CT. On T2WI, three or two layered-target-signs with hyperintensity core were found in 79.2% (141/178) of the lesions. Three layer-target-sign included hyperintensity core, hypointensity rim and slightly high signal halo from the inside out. Two layer-target-sign included hyperintensity core and slightly high signal halo from the inside out. Characteristics of dynamic contrast-enhanced scan included peripheral two or three layered-rim-like enhancement in 66.3%( 118/178) of the lesions;peripheral, gradual rim-like enhancement with enhanced core in 27.0%( 48/178) of the lesions;heterogeneously mild enhancement in 2.2%( 4/178) of the lesions;centripetal enhancement in 4.5%( 8/178) of the lesions. Fifty lesions were found in CT, which showed low density nodules or masses with clear margins. Two-layered-black-target sign were found in 42 lesions in contrast-enhanced images, white-target sign were found in 3 cases, and centripetal enhancement was found in 5 cases. (2) Diffuse form of HEH:in one of the two cases of this type, the lesions could not be separated from normal liver parenchyma, gradual enhancements were found along with the vessels in the center of the lesions. (3) Solitary form of HEH: one case, the lesion showed heterogeneous density in non-contrast CT images and gradual enhancement in contrast-enhanced images. Conclusions We found some imaging characteristics of HEH. Two or three layered-target-sign on T2WI and black-target sign, white-target sign on contrast-enhanced images were unique imaging features of HEH.

Objective To evaluate the value of the neutrophil-lymphocyte ratio (NLR) in elderly type 2 diabetic patients (T2DM) with coronary heart disease (CHD).Methods We performed a retrospective observational study on 228 patients undergoing coronary angiography in Guizhou Provincial People's Hospital from April 2014 to July 2015.Patients were divided into three groups:the simple T2DM group (n=77),simple CHD group (n=72),and T2DM complicated with CHD group (n=79).Meanwhile,70 healthy elderly subjects served as the control group.The white blood cell count,high-sensitivity C-reactive protein (hs-CRP) and other clinical and laboratory parameters were collected,and NLR was calculated.Risk factors for CHD in T2DM patients were determined by logistic regression analysis.Multiple stepwise regression analysis was adopted to identify factors influencing NLR.Results The white blood cell count,neutrophil count,NLR and hs-CRP level in the simple T2DM,CHD,and T2DM+CHD groups were higher than in the control group [(7.48 1.81) 109/L,(7.72± 1.89) 109/L,(7.98±2.12) 109/L vs.(6.22± 1.61) 109/L;(4.49±1.38) 109/L,(4.88±1.56) 109/L,(5.35±1.40) 109/L vs.(3.52±0.84) 109/L;(2.84± 0.77),(3.07±0.79),(3.34±0.83) vs.(1.58±0.42);(2.92±0.65) mg/L,(3.20±0.86) mg/ L,(4.98±1.10) mg/L vs.(1.105±0.23) mg/L;respectively,P＜0.05 or P＜0.01].The lymphocyte count in the simple T2DM,CHD,and T2DM+CHD groups were lower than in the control group [(1.57±0.41) × 109/L,(1.58±0.40) × 109/L,(1.61±0.48) × 109/L vs.(2.22± 0.51) × 109/L,P＜0.05].NLR and hs-CRP levels in the T2DM+CHD group were higher than in the former two groups (all P＜0.05).Pearson correlation analysis showed that NLR was positively correlated with the Gensini score and hs-CRP level (r=0.7455 and 0.7792,both P＜0.01).Logistic regression analysis showed that NLR,hs-CRP levels and glycosylated hemoglobin A1c (HbA1c) were the risk factors for CHD in T2DM patients (OR=4.331,3.997 and 2.928,all P＜0.05).Multiple stepwise regression analysis showed that NLR was positively correlated with fasting plasma glucose,HbA1 c levels and systolic blood pressure (β' =0.3133,0.4720 and 0.3069,all P＜0.05).Conclusions NLR may be a valuable predictive factor for CHD in elderly T2DM patients.

Objective To explore the effects of impaired glucose metabolism and impaired blood lipoprotein metabolism on heart rate variability(HRV) in aged male hypertension patients and to have an insight into the correlation between the years of impaired glucose metabolism and the patients’ HRV. Methods 120 male subjects were divided into three groups: simple hypertension patients (group A, 40 people), hypertension patients with diabetes mellitus (group B, 40 people), and hypertension patients with diabetes mellitus and impaired blood lipoprotein metabolism (group C, 40 people). All subjects had 24h recordings of ECG. The data of HRV time domain were collected and analyzed to gain an insight into the effects of the impaired glucose metabolism and impaired blood lipoprotein metabolism on patients’ HRV. In group C, patients were divided into normal TC subgroup and high TC subgroup according to the index of TC (TC
