OBJECTIVE： To observe effect of Liuweibuqi Capsule, a Traditional Chinese Medicine （TCM）, on the janus kinase （JAK）/signal transducer and activator of transcription （STAT） pathway and matrix metalloproteinases （MMPs） in a chronic obstructive pulmonary disease （COPD） rat model with lung deficiency in terms of TCM＇s pattern differentiation. METHODS： Rats were randomly divided into a normal group, model group, Liuweibuqi group, Jinshuibao group, and spleen aminopeptidase group （n= 10）. Aside from the normal group, all rats were ex-posed to smoke plus lipopolysaccharide tracheal instillation to establish the COPD model with lung deficiency. Models were established after 28 days and then the normal and model groups were given normal saline （0.09 g/kg）, Liuweibuqi group was given Liuweibuqi capsule （0.35 g/kg）, Jinshuibao group was given Jinshuibao capsules （0.495 g/kg）, and the spleen group was given spleen aminopeptidase （0.33 mg/kg）, once a day for 30 days. Changes in symptoms, signs, and lung histology were observed. lung function was measured with a spirometer. Serum cytokines were detected using enzyme-linked immunosorbent assay, and changes in the JAK/STAT pathway, MMP-9, and MMPs inhibitor 1 （TIMP1） were detected by immunohistochemistry, RT-PCR, and western blotting, ***： Compared with the normal group, lung tissue was damaged, and lung function was reduced in the model control group. Additionally, the levels of interleukin （IL）-1β, y interferon （IFN-γ）, and IL-6 were higher, while IL-4 and IL-10 were lower in the model control group than those in the normal group. The expressions of JAK1, STAT3, ρ-STAT3, and MMP-9 mRNA and protein in lung tissue were higher, and TIMP1 mRNA and protein was lower in the model group compared with the normal group. After treatment, compared with the model group, the expression of inflammatory cytokines was lower in each treatment group, and expressions of JAK/ STAT pathway, MMPs were lower. Compared with the positive
