OBJECTIVETo investigate the value of contrast-enhanced ultrasound in the differential diagnosis of solid focal lesions of pancreas (s-FLPs).
METHODSWe retrospectively analyzed the clinical data of 56 s-FLPs examined with contrast agent combined with low mechanical indicators contrast-enhanced ultrasound.
RESULTSThe surrounding pancreas parenchyma enhancement time, lesion enhancement time, and peak enhancement time between different groups of s-FLPs had no significant differences (P > 0.05), while the beginning to peak enhancement time showed significant difference (P < 0.05). When using the enhancement speed as a diagnostic indicator to differentiate pancreatic carcinoma from tumor-like pancreatitis, the sensitivity, specificity, and accuracy were 90.5%, 71.4%, and 85.7% for pancreatic carcinoma and 75.0%, 91.7%, and 89.3% for tumor-like pancreatitis. When using the enhancement pattern as a diagnosis indicator to differentiate pancreatic carcinoma from tumor-like pancreatitis, the sensitivity, specificity, and accuracy were 85.7%, 78.6%, and 83.9% for pancreatic carcinoma and 75.0%, 100%, and 94.6% for tumor-like pancreatitis. When different indicators were combined, enhancement pattern and enhancement speed showed the best diagnostic results; however, the Youden index was not improved.
CONCLUSIONSDifferent s-FLPs show different enhancement findings on contrast-enhanced ultrasound. The enhancement pattern and enhancement speed are the most useful diagnostic indicators.

5.Role of liver fibrosis assessment in decision-making and efficacy surveillance for antiviral therapy in patients with chronic hepatitis B
Journal of Clinical Hepatology 2016;32(11):2058-2061
Liver fibrosis/cirrhosis is the outcome of the progression of chronic hepatitis B and is associated with liver events and long-term prognosis. Effective antiviral therapy can delay or even reverse disease progression. Therefore, assessment of liver fibrosis degree before and during treatment is of great importance in initiating antiviral therapy, developing therapeutic regimens, and monitoring antiviral effects and complications. The semi-quantitative histological scoring system is widely acknowledged in the assessment of liver fibrosis degree and is an important basis for the initiation of antiviral therapy for hepatitis B, as well as a method commonly used for efficacy surveillance. Morphological and structural quantitative methods provide objective histological assessment of liver fibrosis and may cover the shortage of conventional semi-quantitative scoring system. Non-invasive methods for the assessment of liver fibrosis may reduce but not completely substitute liver histological examinations; a consensus has not been reached on their cut-off values to make decisions to initiate antiviral therapy, but such non-invasive methods can provide rich information on therapeutic effect and long-term prognosis.

Objective: To analyze the medication rules of traditional Chinese medicine (TCM) preventive oral prescriptions for COVID-19. Methods: The preventive oral prescriptions for COVID-19 published by national and provincial health and wellness committees, administrations of TCM, medical institutions at all levels, medical masters and Chinese medicine experts were collected to establish a database, manual screening was carried out according to the inclusion and exclusion criteria, and frequency statistics, association rule analysis. The mutual information method, entropy hierarchical clustering and other methods were improved through Excel and the TCM inheritance auxiliary platform V2.5 to mine the rules and characteristics of medication. Results: The selected 157 prescriptions contained a total of 130 TCMs. The top five TCMs with the highest use frequency were Glycyrrhizae Radix et Rhizoma (86), Astragali Radix (80), Lonicerea Japonicae Flos (70), Atractylodis Macrocephalae Rhizoma (62), Saposhnikoviae Radix (60). In accordance with TCM efficacy classification, most of them were medicines for qi-tonifying (279), followed by medicines for clearing heat and drying dampness (163), dispelling pathogenic wind-cold (126), resolving dampness (111), as well as dispelling pathogenic wind-heat (99). The characteristics of four-natures of the selected medicines are as follows: most of them were cold (59), followed by warm (38) and mild (21). In terms of five-taste, most of them were sweet (26) and acrid-and-bitter (24), followed by sweet-and-bitter (20), bitter (20) and acrid (15). For the meridian attribution, the five-zang organs and six-fu organs were all involved, most of them attributed to lung meridian (80), followed by stomach meridian (57) and spleen meridian (40). Based on association rule analysis, 12 commonly used medicine combinations with two or three TCMs were found. The commonly used medicinal pairs included Astragali Radix and Saposhnikoviae Radix (51), Astragali Radix and Atractylodis Macrocephalae Rhizoma (46), Atractylodis Macrocephalae Rhizoma and Saposhnikoviae Radix (43), Astragali Radix and Atractylodis Macrocephalae Rhizoma and Saposhnikoviae Radix (38), Forsythiae Fructus and Astragali Radix (37), and so on. In addition, 14 core combinations of medicines were obtained by complex system entropy cluster analysis, on this basis, six new prescriptions were screened out based on unsupervised entropy hierarchical clustering analysis. According to The Catalogue of Edible Traditional Chinese Medicinal Materials, Traditional Chinese Medicinal Materials for Health Food, and New Resources of Food published by National Health Commission of the People's Republic of China, there are 35 species belonging to the group of edible traditional Chinese medicinal materials, 20 species belonging to the group of new resources of food, 31 species belonging to the group of traditional Chinese medicinal materials for health food, 19.11% of the preventive oral prescriptions for COVID-19 were composed of the medicines belonging to the above three groups. Besides, there are 11 toxic species, and 24.84% of the preventive oral prescriptions for COVID-19 contained toxic TCMs. Conclusion: We found that invigorating qi and resolving dampness were the main treatment used to prevent for COVID-19, combined with the methods for strengthening vital energy and eliminating pathogenic factors. Most of the preventive oral prescriptions for COVID-19 were treated in lung, spleen and stomach meridians. In the process of selecting prescriptions and using TCMs to prevent for COVID-19, the safety of preventive medicines was also emphasized. And the theory of “Preventive Treatment of Disease” was embodied in these preventive oral prescriptions for COVID-19. For the prescriptions containing toxic TCMs, special attention should be paid to their safety in clinical application.
