[Treatment of Mild-to-moderate Bronchial Asthma (Heat Wheezing Syndrome) Patients at Acute Onset with Western Medicine Combined Danlong Oral Liquid: a Multi-center, Randomized Double- blinded, Positive-controlled Clinical Trial].

OBJECTIVE: To observe the efficacy and safety of Danlong Oral Liquid (DOL) combined Western medicine (WM) in treating mild-to-moderate bronchial asthma patients (heat wheezing syndrome) at acute onset. METHODS: Totally 480 mild-to-moderate bronchial asthma patients (heat wheezing syndrome) at acute onset were randomly assigned to two groups in the ratio 3:1, the treatment group (360 cases) and the control group (120 cases). All patients received basic WM treatment. Patients in the treatment group took DOL, 10 mL each time, 3 times per day for 7 days in total, while those in the control group took Kechuanning Oral Liquid (KOL) , 10 mL each time, 3 times per day for 7 days in total. Efficacy for asthma symptoms, lung functions and scores of TCM syndrome and/or main symptoms were evaluated. RESULTS: The percentage of clinical control and significant effectiveness of asthma symptoms in the treatment group was significantly higher than that of the control group (77.36% vs 56.07%, P < 0.01). The percentage of clinical control and significant effectiveness of lung functions in the treatment group was significantly higher than that of the control group (74.28% vs 50.00%, P < 0.01). The anterior-posterior difference in scores of TCM syndrome was significantly superior in the treatment group than in the control group (-11.26 ± 4.70 vs -9.21 ± 5.09, P < 0.01). The anterior-posterior difference in scores of main symptoms was significantly better in the treatment group than in the control group (-6.58 ± 3.08 vs -5.16 ± 3.45, P < 0.01). The incidence of adverse reactions was significantly lower in the treatment group than in the control group [1.73% (6/346 cases) vs 10.17% (12/118 cases) , P < 0.05]. CONCLUSION: DOL combined WM was superior to KOL in treating mild-to-moderate bronchial asthma patients (heat wheezing syndrome) at acute onset.

[Matrine and anti-tumor drugs in inhibiting the growth of human lung cancer cell line].

OBJECTIVE: To study the activities of matrine and anti-tumor drugs on SPCA/I human lung adenocarcinoma cell line. METHODS: Suppression effects of different concentrations of matrine and matrine combined with anti-tumor drugs on lung cancer cells were measured by methyl thiazolyl tetrazolium (MTT) colorimetric assay. RESULTS: Different concentrations of matrine could inhibit the growth of SPCA/I human lung adenocarcinoma cells and there was a positive correlation between the inhibition rate and the drug concentration. Different concentrations of matrine combined with anti-tumor drugs had higher growth inhibition rate than anti-tumor drugs alone. CONCLUSION: Matrine has direct growth suppression effect on SPCA/I human lung adenocarcinoma cells and matrine combined with anti-tumor drugs shows a significant synergistic effect on tumor cells.
