RESUMEN
Objective To investigate the characteristics of symptom burden and extract symptom clusters in lung cancer patients at the end of thoracic radiotherapy.Methods Lung cancer patients receiving Thoracic Radiotherapy were collected from 20 tertiary hospitals in China,including Guang'anmen Hospital of the Chinese Academy of Traditional Chinese Medicine,during November 2014—September 2017,and the MDASI-TCM scale assessed patient symptoms at the end of radiotherapy,and descriptive statistics and exploratory factor analysis explored symptom burden and the distribution of TCM symptom clusters.Results At the end of radiotherapy,45.1%of patients reported two or more moderate to severe symptoms,with fatigue being the most prevalent and severe symptom.Fatigue(31.4%),cough(30.9%),expectoration(24.1%),distress(23.2%)and shortness of breath(20.9%)were the top five symptoms from the highest to the lowest in the incidence of moderate to severe symptoms.The enjoyment of life(36.4%)had the highest incidence of interference with moderate to severe symptoms.Exploratory Factor analysis extracted three symptom clusters,namely the excessive heat and damaged yin-Spleen and stomach disorders related symptom cluster,the heart and spleen-deficient related symptom cluster,and the lung qi-unfriendly related symptom cluster,with a cumulative variance contribution of 70.1%.Conclusion Lung cancer patients undergoing thoracic radiotherapy have a certain symptom burden at the end of radiotherapy.The identification of symptom burden and symptom group characteristics is conducive to promoting standardization of TCM syndrome differentiation and laying a preliminary foundation for formulating reasonable and effective TCM intervention measures in the future.
RESUMEN
Objective To observe the effects of dredging collaterals and activating blood worm Chinese materia medica on angiogenesis related factors of lung cancer in hypoxic environment. Methods The lung cancer A549 cells were cultured in vitro to simulate tumor hypoxia microenvironment by the hypoxia workstation, and different concentrations of Scorpio, Scolopendra and Gecko medicated serum were added. MTT method was used to detect cell proliferation and screen the best medicine concentration and duration of action. Lung cancer A549 cells were administrated by the three kinds of medicated serum, and cells were collected and supernatant was cultured. Contents of VEGF, TGF-β1, and bFGF were detected by ELISA. Results Three kinds of medicated serum had the inhibitory effect on both added normoxia and hypoxia in cultured A549 lung cancer cells. 7.5% concentration of medicated serum was selected, and 24 h later were used in later experiments. Scorpio, Scolopendra and Gecko medicated serum can more reduce the contents of VEGF, TGF-β1 and bFGF in the supernatant of A549 cell compared with the control group (P<0.05, P<0.01). Conclusion Dredging collaterals and activating blood worm Chinese materia medica had inhibitory effect on cancer cells and the regulation of angiogenesis related cytokines in the condition of normoxia and hypoxia.
RESUMEN
Objective To observe the initial mechanism investigation in immune escaping correlated T cell proportion of Lewis lung cancer by Fuzheng-Peiyuan formula. To provide a theoretical basis for the application of the Chinese medicine of strengthening the body resistance in clinics. Methods The healthy C57BL/6J mice were divided into six groups by the random number table: the Chinese medicine group, the Chinese medicine plus chemotherapy group, the chemotherapy group, the model group and the normal control group. There were 6 mice in each group. All the groups expect the normal control group were inoculated subcutaneously with Lewis lung cancer cell suspension 0.2 ml. The medicine given to the Chinese medicine group were orally Fuzheng-Peiyuan formula with 8.17 g/kg. The combination group was given intraperitoneal injection of cyclophosphamide 60 mg/kg and orally Fuzheng-Peiyuan formula 8.17 g/kg. The chemotherapy group received the injection of cyclophosphamide 60 mg/kg and intragastric administration of normal saline. The model group and normal control group were administered with saline. After continuous administration for 13 days, the expressions of CD4, Foxp3, CD8 and CD28 in spleen cells of tumor bearing mice were observed by flow cytometry. Results Compared with the model group, the chemotherapy group and the chemotherapy combined with Chinese traditional medicine group showed that tumor weight (1.76 ± 0.42 g, 1.40 ± 0.43 g vs. 4.37 ± 0.59 g) significantly decreased (P<0.01); and the CD4+ Foxp3+ cells of mouse spleen cells in the Chinese medicine group and Chinese medicine plus chemotherapy group (11.25% ± 1.69%, 9.30% ± 2.68% vs. 14.21% ± 1.50 %) significantly decreased (P<0.05 or P<0.01). Conclusions The result initial proved that the Chinese medicine could strengthen the body resistance, adjust the proportion of Treg and CTL in spleen T cell in tumor-bearing mouse.
RESUMEN
Objective To investigate the distributing characteristics of blood stasis syndrome on 300 cases of advanced stage lung cancer patiens. Method Through filling in the table-syndrome of distributing characteristics of primary pulmonary carcinoma for stage Ⅲ and Ⅳ patients,the distributing characteristics of blood stasis syndrome in advanced lung cancer patiens were observed. Result The constituent ratio of blood stasis syndrome increased significantly following the worse patho-typing degree,the cell differentiation degree,the occurrence of hepatic metastasis,opposite pulmonary metastasis,osseous metastasis and troisier sign. Conclusion The syndrome of blood stasis of lung cancer has the distinct feature. Accordingly,the diagnostic standard which can be qualified of syndrome of blood stasis should be established. Only in that way can we guide the clinical diagnosis,the evaluation of therapeutic effect and the clinical trial of new drug of TCM preferably.
