ABSTRACT
Objective@#To analyze the CT signs of peripheral lung cancer.@*Methods@#From July 2012 to June 2017, the clinical data of 85 patients with peripheral lung cancer examined by CT in the People's Hospital of Longyou County were retrospectively analyzed.CT findings were analyzed and compared with the results of postoperative pathological diagnosis.@*Results@#CT examination showed that the lesions were located in the posterior segment of the right upper lung, the dorsal segment of the double lower lobe, the posterior segment of the left superior pulmonary apex, the anterior segment of the bilateral upper lobe and the posterior basal segment of the right lower lobe in 56 cases, accounted for 65.88%.The shape of the mass was spherical or nearly spherical in 95.29%.The diameter of the mass ≤50mm in 58 cases, accounted for 68.23%.The density of the mass was even in 72 cases, and 13 cases were inhomogeneous.The proportions of lobulation sign, burr sign, spinous process sign, pleural depression sign, bronchovascular concentration sign and vacuole sign were 94.12%, 88.24%, 89.41%, 92.94%, 52.94%, 88.24%, respectively.@*Conclusion@#CT findings and case-based analysis of patients with peripheral lung cancer are of great importance in the diagnosis of patients with peripheral lung cancer, and play a significant role in the clinical efficacy.
ABSTRACT
Objective: To establish the quality criteria for xiaozhining tablet. Methods: TLC method was applicated to determine and differentiate the Scutellaria , the Radix salviae miltiorrhizae, the Rheum, the Leonurus of the tablet. HPLC method was used for detecting the content of emodin in xiaozhining Tablet. Results: Four main components of the tablet was determined well. The regression equation by HPLC was A=2.43?10 7C+6.06?10 4(r=0.999 7). Curcumin had good linear relation within the range of 0.5～0.05 mg/ml. The average recovery rate was 96.70%(RSD=1.06%). The average value of emodin was 0.021 4 mg. Conclusion: The method of determination is reliable. It can be used as the basis for the quality control of xiaozhining Tablet.
