Antitumor Activity of Xerophilusin G on S180 Cells / 医药导报

Objective To study the antitumor activity of Xerophilusin G on S180 cells,and Its mechanism.Methods Modified MTT assay was used to test the effect of Xerophilusin G on the proliferation of S180 tumor cell strain.The influences on tumor growth and immune organs of mice with transplanted sarcoma (S180) were observed.The cell cycle of S180 cell lines and mouse sarcoma (S180) was analyzed by flow cytometry.The lymphocyte proliferation activity of spleen stimulating was tested.The level of IL-2 in serum of mice with transplanted sarcoma (S180) was measured by ELISA.Results The IC50 of Xerophilusin G in S180 cell lines was 19.80 μg·mL-1,the LD50 in mouse for Xerophilusin G was 121.11 mg·kg-1 through intraperitoneal injection.The tumor inhibition rate of Xerophilusin G was 32.11％ and 41.60％,respectively at the doses of 3 and 6 mg · kg-1 (P ＜ 0.05).Compared with the control,the thymus,kidney and cardiac index were decreased.The cell proportion at G0/G1 phase of mouse sarcoma (S180) was increased.T and B cell proliferation activities in tumor-bearing mice were enhanced (P ＜ 0.05).As compared with control group,the serum level of IL-2 was decreased 90.9％ and 77.1％ in low-and medium-dose groups,respectively (P ＜ 0.05).Conclusion Xerophilusin G has remarkable effects in sarcoma (S180) bearing mice.The antitumor mechanism of Xerophilusin G might be related with G0/G1 phase arrest of mouse sarcoma (S180) cells and enhancing the activity of T and B cell but not related with increasing the secreting of IL-2.

Analysis of Clinical Characteristics and Misdiagnosis of 178 Patients with Pulmonary Embolism / 昆明医科大学学报

Objective The study aimed to analyze the clinical data of patients with pulmonary embolism and summarize the clinical characteristics of pulmonary embolism,in order to improve the correct diagnostic rate and the prognosis. Methods Data of 178 patients who were cured in our hospital from January 2011 to December 2014 were analyzed retrospectively,including relative risk factors,clinical behaviors,examination data,misdiagnosis and prognosis. Results Patients with pulmonary embolism had related basic diseases and risk factors. Their clinical symptoms,signs and ordinary detection methods indicated pneumatorexis and cardiovascular injury,but lacked of specificity. The misdiagnosis rate of the first diagnosis was 48.88%,including 22 cases of the misdiagnosis to COPD, 18 cases to pneumonia and 16 cases to coronary heart disease. The misdiagnosis rate of elderly patients was 56.36%, while that of the young and middle-aged patients was 36.80%,the difference was statistically significant,P 0.05). Conclusion Although the related risk factors of pulmonary embolism in patients existed,the misdiagnosed rate of the disease was high and prognosis was poor due to many confusing basic diseases. And the symptoms,signs and ordinary inspection of the patients lacked specificity. CTPA,being utilized to diagnose pulmonary embolism reliably,should be promoted.
