Objective To explore the pathological features of lung tissue in mild chronic obstructive pulmonary disease(COPD)and their association with inflammatory factors.Methods A total of 70 patients who underwent surgery for small lung nodule were prospectively included,and were divided into the normal group(n=10),the mild COPD group(n=50)and the moderate and severe COPD group(n=10).The pathological changes of lung tissue were evaluated after HE,Masson and EVG staining.The expression levels of SMA,Actin and CD31 proteins were detected by immunohistochemistry staining.Tumor necrosis factor α(TNF-α),interleukin-10(IL-10)protein and mRNA levels were detected by immunohistochemistry and qPCR.Results Pulmonary tissue in mild COPD showed widening of alveolar septum,dilation of small airways,mild thickening of blood vessel wall and inflammatory reaction dominated by lymphocyte infiltration.Immunohistochemistry staining showed that contents of SMA and Actin proteins in mild COPD lung tissue were higher than those in the normal group(P＜0.05).In addition,the TNF-α mRNA and the positive rate of TNF-α in lung tissue of mild COPD were significantly higher than those in the normal group,while the IL-10 mRNA was significantly lower than that of the normal group(all P＜0.05).SMA and Actin were positively correlated with the positive expression of inflammatory cytokine TNF-α,but negatively correlated with the positive expression of IL-10(all P＜0.05).Conclusion The main pathological changes of lung tissue in mild COPD include small lung blood vessel remodeling ocharacterized by thickening of small blood vessel smooth muscle layer and lymphocyte-dominated inflammatory response,while the increase of pro-inflammatory factor TNF-α and decrease of anti-inflammatory factor IL-10 are associated with pathological changes of COPD.

Polyphyllin Ⅰ(PPⅠ)and polyphyllin Ⅱ(PⅡ)are the main active substances in the Paris polyphylla.However,liver toxicity of these compounds has impeded their clinical application and the potential hepatotoxicity mechanisms remain to be elucidated.In this work,we found that PPⅠ and PⅡ exposure could induce significant hepatotoxicity in human liver cell line L-02 and zebrafish in a dose-dependent manner.The results of the proteomic analysis in L-02 cells and transcriptome in zebrafish indicated that the hepa-totoxicity of PPⅡ and PⅡwas associated with the cholesterol biosynthetic pathway disorders,which were alleviated by the cholesterol biosynthesis inhibitor lovastatin.Additionally,3-hydroxy-3-methy-lglutaryl CoA reductase(HMGCR)and squalene epoxidase(SQLE),the two rate-limiting enzymes in the choles-terol synthesis,selected as the potential targets,were confirmed by the molecular docking,the over-expression,and knockdown of HMGCR or SQLE with siRNA.Finally,the pull-down and surface plasmon resonance technology revealed that PPⅠ could directly bind with SQLE but not with HMGCR.Collectively,these data demonstrated that PPⅠ-induced hepatotoxicity resulted from the direct binding with SQLE protein and impaired the sterol-regulatory element binding protein 2/HMGCR/SQLE/lanosterol synthase pathways,thus disturbing the cholesterol biosynthesis pathway.The findings of this research can contribute to a better understanding of the key role of SQLE as a potential target in drug-induced hepatotoxicity and provide a therapeutic strategy for the prevention of drug toxic effects with similar structures in the future.

Ganoderma lucidum is a mushroom widely used for its edible and medicinal properties. Primary bioactive constituents of G. lucidum are ganoderic triterpenoids (GTs), which exhibit important pharmacological activity. Abscisic acid (ABA), a plant hormone, is associated with plant growth, development, and stress responses. ABA can also affect the growth, metabolism, and physiological activities of different fungi and participates in the regulation of the tetracyclic triterpenes of some plants. Our findings indicated that ABA treatment promoted GT accumulation by regulating the gene expression levels (squalene synthase (sqs), 3-hydroxy-3-methylglutaryl-CoA reductase (hmgr), and lanosterol synthase (ls)), and also activated cytosolic Ca²⁺ channels. Furthermore, under ABA mediation, exogenous Ca²⁺ donors and inhibitors directly affected the cytosolic Ca²⁺ concentration and related gene expression in Ca²⁺ signaling. Our study also revealed that ABA-mediated cytosolic Ca²⁺ played a crucial regulatory role in GT biosynthesis, accompanied by antioxidant defense modulation with increasing superoxide dismutase (SOD) activity and ascorbate peroxidase (APX) activity, and the resistance ability of O₂^•- and glutathione (GSH) contents.

Wumeiwan are recorded in the Jueyin chapter of Treatise on Cold Damage and Miscellaneous Diseases （《伤寒杂病论》）， and many doctors in the past dynasties believed that they had the effects of calming intestinal ascarid by warming Zang organs. The clinical application was limited. Since KE Qin， a doctor in the Qing dynasty， proposed that Wumeiwan were the primary prescription against Jueyin diseases， Wumeiwan have been valued by doctors， and their clinical application has also been expanded. The syndrome indicated for Wumeiwan is attributed， not only to the ascarid internal harassment， but to the abnormal Qi movement of wind and wood in Jueyin and the dysfunction of Yin and Yang. According to the functions of six meridians based on the theory of "open-close axis" in Huangdi's Internal Classic （《黄帝内经》） and the original texts of Treatise on Cold Damage and Miscellaneous Diseases， Yinshu refers to Jueyin. Wumeiwan， the primary prescription against Jueyin diseases， have the function of connecting Yin and Yang， and they can treat diseases caused by Qi disturbance of Jueyin and cold and heat in complexity. Sharing the same resource， the Secrets for Auxiliary Cultivation Life： The Essential Method of Using Herbal Medicine for the Differential Treatment of the Five Zang Organs （《辅行诀五脏用药法要》） and Treatise on Cold Damage and Miscellaneous Diseases both consult Models of the Classic of Decoction （《汤液经方》）. The formulation rules of tonic/purgative and collapse-saving prescriptions in Secrets for Auxiliary Cultivation Life follow the recorded "Tang Ye Jing Fa Tu" （an image revealing the compatibility principles of Chinese herbal drugs） and are closely related to the five elements theory. By exploring the formulation rules in "Tang Ye Jing Fa Tu" and the five elements of drugs， this study analyzed Wumeiwan and proved that Wumeiwan mainly acted on the liver， spleen， and heart. According to the Five Zang-organs Storing Spirit theory from Huangdi's Internal Classic， the above three organs are closely related to emotional adjustment. Therefore， the treatment of emotional disorders caused by qi disturbance of Jueyin and cold and heat in complexity with Wumeiwan is supported by evidence. At the end of this article， the reports on the treatment of emotional disorders with Wumeiwan in recent years were listed and reviewed. This article provides new ideas for the clinical application of Wumeiwan in the treatment of emotional disorders and expands the application range.

Polycyclic aromatic hydrocarbons (PAHs) are a class of persistent pollutants that are widely distributed in the environment. Due to their stable structure and poor degradability, PAHs exhibit carcinogenic, teratogenic, and mutagenic toxicity to the ecological environment and organisms, thus increasing attentions have been paid to their removals and remediation. Green, safe and economical technologies are widely used in the bioremediation of PAHs-contaminated soil. This article summarizes the present status of PAHs pollution in soil of China from the aspects of origin, migration, fate, and pollution level. Meanwhile, the types of microorganisms and plants capable of degrading PAHs, as well as the underlying mechanisms, are summarized. The features of three major bioremediation technologies, i.e., microbial remediation, phytoremediation, and joint remediation, are compared. Analysis of the interaction mechanisms between plants and microorganisms, selection and cultivation of stress-resistant strains and plants, as well as safety and efficacy evaluation of practical applications, are expected to become future directions in this field.
