Pulmonary disease is one of the major threats to human health. However, the current clinical treatment drugs for lung diseases generally have problems such as low lung delivery efficiency, fast clearance rate and obvious toxic side effects. Recently, membrane biomimetic nanocarriers have attracted more and more attention. Due to their advantages of high targeting, long cycle time, good biocompatibility and strong immune escape ability, membrane biomimetic nanocarriers have become a major research hotspot in targeted therapy of lung diseases. In this review, we discuss the main preparation methods of membrane biomimetic nanoparticles, the characteristics of membrane biomimetic nanocarriers from different cell sources and their application in the targeted therapy of lung diseases. At the same time, according to the characteristics of different membranes, the shortcomings, current technical limitations and future prospects are discussed. This review is expected to provide references for the design of membrane biomimetic nanocarriers and their potential applications in the treatment of lung diseases.

It is believed that children bronchiolitis obliterans （BO） is located at the lung and closely related to the spleen and kidney. Phlegm， stasis， block and deficiency are the main pathogenesis. This article promotes staged differentiation and treatment of BO considering the clinical manifestations and pathogenesis characteristics. The attack stage is dominated by phlegm and stasis blocking the lung， for which the method of dissolving phlegm and dispelling stasis， relieving cough and calming panting should be used； Xiaoqinglong Decoction（小青龙汤） and Sanzi Yangqin Decoction （三子养亲汤） with modifications and selfmade Modified Wuhu Decoction （五虎汤加味） are recommended for cold-phlegm blocking the lung syndrome and phlegm heat blocking the lung syndrome， respectively. In sustained stage， the upper excess and lower deficiency together with phlegm-stasis blocking the lung are the pathogenesis， for which the method of dissolving phlegm and dispelling stasis， reopening the block and supplementing deficiency is suggested， and Xiaoqinglong Decotion （小青龙汤） and Duqi pills （都气丸） with modifications can be used. In convalescent stage， the pathogenesis is lung-spleen-kidney depletion with residual pathogen. It suggested to supplement the deficiency and consolidate the root， as well as clear the residual pathogen， for which Baogen NO.1 Decoction （宝根1号方） with modifications can be used.

Cells undergo glucose metabolism reprogramming under the influence of the inflammatory microenvironment, changing their primary mode of energy supply from oxidative phosphorylation to aerobic glycolysis. This process is involved in all stages of inflammation-related diseases development. Glucose metabolism reprogramming not only changes the metabolic pattern of individual cells, but also disrupts the metabolic homeostasis of the body microenvironment, which further promotes aerobic glycolysis and provides favourable conditions for the malignant progression of inflammation-related diseases. The metabolic enzymes, transporter proteins, and metabolites of aerobic glycolysis are all key signalling molecules, and drugs can inhibit aerobic glycolysis by targeting these specific key molecules to exert therapeutic effects. This paper reviews the impact of glucose metabolism reprogramming on the development of inflammation-related diseases such as inflammation-related tumours, rheumatoid arthritis and Alzheimer's disease, and the therapeutic effects of drugs targeting glucose metabolism reprogramming on these diseases.
