After the homogeneity test of variance, the comparison between the groups before and after treatment adopts an independent sample t test, and the comparison in the same group adopts single factor variance analysis. The count data is expressed as an example (%), and Pearson χ is used as the classification count data 2 The assay was performed. P (P)<0.05 is a significant difference with statistical significanceMeaning.
Study results:
general data of patients were collected, age, sex, smoking history, no obvious differences, and the two groups of patients were comparable. Table 6 shows the efficacy of the Chinese medicinal composition on acute lung injury. The total effective rate of the traditional Chinese medicine group can reach 96.7%, the curative effect of the traditional Chinese medicine group is superior to that of a control group, and the difference has statistical significance (P < 0.01). The traditional Chinese medicine composition is proved to obviously relieve the symptoms of patients, and the total effective rate of the traditional Chinese medicine composition is superior to that of the traditional Chinese medicine composition for treatment by combination with the traditional Chinese medicine composition. Table 7 shows the effect of the Chinese medicinal composition on the inflammatory index of patients with acute lung injury. Compared with the control group, the neutrophil ratio and C-reactive protein of the traditional Chinese medicine group patients are obviously reduced (P < 0.01). The traditional Chinese medicine composition can reduce inflammation of patients. Through safety monitoring, adverse reactions do not occur to patients in the traditional Chinese medicine group. The traditional Chinese medicine composition has good safety and definite clinical curative effect, and has important clinical value on acute lung injury.
