ABSTRACT
Context: Liuweibuqi (LWBQ) capsule has been reported to influence symptoms of patients with chronic obstructive pulmonary disease (COPD); however, specific function of LWBQ capsules in COPD with lung-qi deficiency syndrome remains elusive.Objective: This study investigates effect of LWBQ capsules on STAT4/STAT6 and MMP-9/TIMP-1 expression and pulmonary function in stable COPD with lung-qi deficiency syndrome.Materials and methods: Totally, 429 patients diagnosed with stable COPD and lung-qi deficiency syndrome were treated with starch capsules (each time for 9 capsules), or different doses: low (each dose for 8 capsules and 1 LWBQ capsules), medium (each time for 6 capsules and 3 LWBQ capsules), or high (each time for 9 LWBQ capsules) of LWBQ capsules for 30 days, 3 times a day. Forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC), FEV1/FVC% and DLco%pred were evaluated by pulmonary function meter. STAT4/STAT6 and MMP-9/TIMP-1 expression was assessed by RT-qPCR and western blot analysis, and serum concentrations of IL-4, IFN-γ and IL-6 by ELISA.Results: Spearman rank correlation analysis and ROC curve showed that STAT4/STAT6 and MMP-9/TIMP-1 affected pulmonary functions and curative effect of stable COPD with lung-qi deficiency syndrome. After LWBQ capsule treatment, FEV1, FVC, FEV1/FVC% and DLco%pred elevated; STAT4/STAT6, MMP-9/TIMP-1, IFN-γ and IL-6 expression declined whereas IL-4 expression increased (p < 0.05). Logistic regression analysis demonstrated that FEV1/FVC was negatively correlated with STAT4/STAT6 and MMP-9/TIMP-1 expression in COPD patients.Conclusions: LWBQ capsules play a beneficial role in pulmonary function of stable COPD with lung-qi deficiency syndrome via STAT4/STAT6 and MMP-9/TIMP-1.

Professor LIN Guo-hua is the representative inheritor of Lingnan fire needling therapy. He proposed that the clinical application of Lingnan fire needling is mainly based on pattern differentiation according to eight priciples, as well as in coordination with the theories of meridians and zang-fu organs. He believes that dry eye syndrome can be treated from the aspects of deficiency of liver and kidney, heart yin deficiency, and qi and yin deficiency. Through deeply digging the connotation of ancient classics, and combined his clinical practice using Lingnan fire needling, professor LIN created a unique therapy that select "Neichengqi"as the main acupoint combined with Xialeidian, Dagukong (EX-UE 5), Xiaogukong (EX-UE 6) and Shaoze (SI 1) in the treatment of dry eye syndrome. In this paper, from the etiology and pathogenesis of dry eye syndrome and therapeutic characteristics of Lingnan fire needling, the thoughts of syndrome differentiation and characteristics of acupoints selection of professor LIN were analyzed by a typical case, and it is expect to enrich the clinical treatment plan for dry eye syndrome.
