Objective:To explore value of 256-slice spiral CT pulmonary artery angiography (CTPA)evaluating right heart function in patients with acute pulmonary embolism (APE).Methods:According to death risk assessment of APE patients, a total of 67 APE patients were divided into high risk APE group (n=41)and non-high risk APE group (n=35).CTPA was used to analyze and compare CTPA obstructive index and right heart function indexes between two groups.Correlations among CTPA obstructive index and right heart function indexes were also analyzed.Results:Compared with non-high risk APE group,there were significant rise in CTPA constructive index [8.58% vs.24.69%],percentages of straight or left protruded ventricular septum (31.46% vs.73.17%)and bronchial artery dilation (5.71% vs.24.69%);Except the supe- rior vena cava diameter,the rest right heart function parameters had difference significance in two groups,P<0.05 or<0.01. Spearman correlation analysis indicated that CTPA obstructive index was significant positively correlated with right ventricular maximal short axis (RVMSA),RV:LV,diameters of main pulmonary artery,superior vena cava and azygos (r=0.684~0.954),and significant inversely correlated with LVMSA (r=-0.786),P<0.01 all.ROC curve analysis indicated that AUCs of CTPA RV:LV (0.949)was the biggest diagnosing APE severity.Conclusion:Right heart func- tion indexes measured by multi-detector CT are accurate and practical indexes evaluating APE severity,and it possesses im- portant significance.

Objective To investigate the current status of prevalence and its relative factors of non-alcoholic fatty liver disease (NAFLD) in the elderly in urban community in Ningxia province and to compare the differences in prevalence of NAFLD between Han and Hui ethnicities.Methods 1046 residents aged 55 years and over from five communities were selected.Questionnaire survey and clinical examination were conducted in all subjects.Fasting vein blood samples were collected.The serum total cholesterol,triglyceride,high density lipoprotein cholesterol,low density lipoprotein cholesterol were detected.Results There were 1043 subjects with average age of (66.41 6.65) years finishing the whole examination,including 696 (66.7％) Han and 347 (33.3％) Hui people.The total prevalence of NAFLD was 27.0％ (286/1043),and there was a significant difference in the prevalence [23.4％ (94 cases) vs.29.9％ (192 cases),x2 =5.18,P=0.023]between male and female,but no difference between Han and Hui ethnicities [28.2％ (98 cases) vs.27.0％ (188 cases) x2 =0.17,P=0.675].Logistic regression showed that age(OR=0.96,95％ CI:0.94-0.99),BMI(OR=1.31,95％ CI:1.24-1.38),TG(OR=1.71,95％ CI:1.47-1.98),central obesity (CO)(OR=5.20,95％CI:2.21-12.23) were the factors correlating with NAFLD.Conclusions The prevalence of NAFLD in Hui elderly people was is similar to that in Han elderly people.The elderly people with overweight,central obesity and high serum level of triglyceride and high level TG have higher risk for NAFLD.

Objective: To assess the clinicopathological and radiological imaging characteristics of patients with primary breast lymphoma. Methods: The clinical and imaging data of patients diagnosed with primary breast lymphoma in West China Hospital of Sichuan University from January 2011 to October 2017 were retrospectively analyzed. The imaging modalities were assessed by mammography, B-ultrasound and PET-CT. The clinicopathological features and radiological imaging characteristics of breast lesions were summarized and analyzed. Results: The fifty-three patients with 70 intramammary lesions were contained in this research. Most patients were females (n = 52, 98.11%), and the median age was 48 years old. Primary breast lymphoma were divided into non-Hodgkin lymphoma (NHL) (n = 51, 96.23%) and Hodgkin lymphoma (HL)(n = 2, 3.77%). Among the patients with NHL, there were 33 cases (62.26%) of diffuse large B-cell lymphoma, 5 cases (9.43%) of B-cell lymphoma, 5 cases (9.43%) of extranodal natural killer (NK)/T-cell lymphoma (nasal type), 2 cases (3.77%) of mantle cell lymphoma, 2 cases (3.77%) of follicular cell lymphoma, 2 cases (3.77%) of T-lymphoblastic lymphoma, 1 case (1.89%) of anaplastic large cell lymphoma, and 1 case (1.89%) of plasmacytic lymphoma. There was no statistical difference (all P > 0.05) in the maximum transverse diameter and the number of lesions among the pathological subtypes. The mammography showed that the most common manifestations were high density irregular lumps with indistinct edges. B-ultrasound showed that the lessions were presented as the irregular masses with hypoechoic pattern and circumscribed margins. PET-CT showed the majority of lesions were solitary or multiple intramammary masses with irregular shape and circumscribed margins. The percentages of lesions classified by mammography, PET-CT and B-ultrasound as breast imaging-reporting and data systems (BI-RADS) 4-5 were 100%, 94.50% and 86.10%, respectively. Conclusion: The imaging manifestations of primary breast lymphoma are varied and unique. PET-CT has good diagnostic value for the BI-RADS classification of primary breast lymphoma.

Sepsis is a life-threatening organ dysfunction caused by the host disordered response to infections.As one of the most important innate immune cells in the body，macrophages can maintain the immune homeostasis by recruiting other immune cells，clearing pathogens，presenting antigens，and play important regulatory roles in infectious diseases such as sepsis by releasing inflammatory factors.As a critical neurotransmitter，dopamine not only participates in the neurological processes such as learning and cognition，but also regulates the immune processes，including regulating the activation，proliferation and functional changes of immune cells such as neutrophils，lymphocytes，monocytes and macrophages.Current studies demonstrate that during the infection and inflammation process of sepsis，the phagocytosis，polarization，and release of inflammatory factors of macrophages are regulated by dopamine.This review summarized the recent research progress on the regulatory functions and the underlying mechanisms of dopamine on macrophages in sepsis.
