Objective To investigate the CT features of renal oncocytoma(RO),and to analyze the causes of misdiagnosis.Methods CT and clinical data of 1 2 patients with RO confirmed by surgery and pathology were analyzed retrospectively,the CT features and the causes of misdiagnosis before operation were analyzed and summarized.Results According to CT features before operation,among the 1 2 cases of RO,9 were misdiagnosed as renal carcinoma,3 were considered as benign occupying lesions.There were 6 cases located in the left kidney and 6 in the right kidney.Seven cases showed round mass and 5 showed irregular mass.Plain CT showed homogeneous masses in 6 cases and heterogeneous masses in 6 cases.Enhanced CT showed masses with homogeneous enhancement in 2 cases and masses with progressive enhancement in 10 cases.The attenuation value of parenchymal enhancement ranged from 41 to 143 HU (mean 90.17 HU).Seven cases had central scar syndrome,of which 1 case had calcification in the scar.One case showed segmental enhancement inversion,8 showed conical interface and 5 had holding ball signs.Conclusion The CT features of RO is central scar syndrome, segmental enhancement inversion,conical interface and holding ball sign,etc,but the definitive diagnosis still rely on pathology.

With the appearance of direct-acting antivirals (DAAs), breakthroughs have been achieved in the antiviral therapy for hepatitis C and hepatitis C patients can be cured completely. Due to the insidious onset of hepatitis C, most patients do not know their own conditions, and thus expanding diagnosis and treatment through screening is the key to the elimination of hepatitis C. However, hepatitis C virus is distributed widely and unevenly in the world, which results in difficulties in the screening and diagnosis of hepatitis C. This article introduces the current economic research on hepatitis C screening, analyzes the factors affecting the cost-effectiveness of hepatitis C screening, and shares the strategies and advances for hepatitis C elimination in other countries, so as to provide a reference for eliminating hepatitis C in China.

Objective:To compare the specific IgE positive rates of the patients between allergic respiratory diseases and respiratory infectious diseases in Guangzhou, the relationship between the co-sensitization of house dust mite (HDM) allergen and Aspergillus fumigatus (AF) allergen and asthma, allergic rhinitis with asthma, pneumonia, upper respiratory infections, bronchitis, serum total immunoglobulin E (total Immunoglobulin E, tIgE) and age were analyzed, to provide the basis for the prevention and treatment of respiratory allergic diseases and respiratory infectious diseases in this area.Methods:A total of 2 535 patients with confirmed respiratory allergic diseases and respiratory infectious diseases were selected retrospectively from the outpatient or inpatient department of the First Affiliated Hospital of Guangzhou Medical University from April 2017 to June 2021 and detected HDM and AF specific IgE (sIgE) by the ImmunoCAP system. The age range was 1 to 89 years. The median age was 5 years. The average age was 9. ≤3 years old group n=894, 4-6 years old group n=721, 7-18 years old group n=615, 19-49 years old group n=207, >49 years old group n=98. There were 1 596 males (62.96%) and 939 females (37.04%). There were 1 279 cases of allergic diseases and 1 256 cases of respiratory infectious diseases. The different disease groups were divided into asthma group (411 cases), allergic rhinitis group (458 cases), allergic rhinitis combined with asthma group (410 cases), pneumonia group (463 cases), upper respiratory tract infection group (299 cases) and bronchitis group (494 cases). The difference of specific IgE (sIgE) and tIgE between HDM and AF was analyzed. For statistical analysis, continuous variables were tested by Mann-Whitney U. Classification data by chi-square test or Fisher′s exact test. Results:1 313 (51.79%) patients were sIgE positive for HDM allergen, 65 (2.56%) were sIgE positive for AF allergen, and 50 (1.97%) were both positive. In the respiratory allergic disease group, 877 cases (68.57%,877/1 279) were positive for HDM allergen sIgE, 57 cases (4.46%,57/1 279) were positive for AF allergen sIgE, and 44 cases (3.44%,44/1 279) were both positive; 436 cases (34.71%,436/1 256) of respiratory infectious diseases were positive for HDM allergen sIgE, 8 cases (0.64%,8/1 256) were positive for AF allergen sIgE, and 6 cases (0.48%,6/1 256) were both positive. In monosensitization, the HDM allergen sIgE sensitization rate was the highest in the allergic rhinitis & asthma group, at 80.24% (329/410). The positive rate of HDM allergen sIgE in male patients was 53.76%(858/1 596), and the positive rate in female patients was 46.22%(434/939), and the difference between the two was statistically significant (χ 2=13.449, P<0.001). In polysensitization, asthma patients (5.35%,22/411) had the highest positive rate of HDM sensitization with AF, followed by allergic rhinitis patients (3.06%,14/458), allergic rhinitis with asthma (1.95%,8/410). The positive rate of respiratory infectious diseases such as pneumonia (0.43%,2/463), upper respiratory infections (0.33%,1/299), and bronchitis (0.61%,3/494) with AF was extremely low. The positive rate of HDM combined with AF in infants(≤3 years old group,0.34%, 3/894; 4-6 years old group, 0.97%, 7/721)was significantly lower than that in teenagers and adults(7-18 years old group,3.58%, 22/615; 19-49 years old group,6.28%, 13/207;>49 years old group,5.10%, 5/98).In the patients with HDM and AF combined sensitization, HDM sIgE levels were distributed in all grades, and AF sIgE levels were mainly in grades 1, 2, and 3. Conclusion:The positive rate of HDM combined with AF was higher in patients with respiratory allergic diseases such as asthma, allergic rhinitis, and allergic rhinitis combined with asthma, suggesting that clinical attention should be paid to the combination of HDM and AF in patients with asthma and allergic rhinitis, especially adults, more likely to be combined with AF.
