Osteoarthritis(OA)is a common joint disease in clinical practice,and cartilage damage is a typical pathological change.The pathogenesis of OA is complex,and various adverse factors can lead to the occurrence of OA.Mitochondria are im-portant organelles within cells and play important roles in cellular physiological and pathological activ-ities.Mitochondrial quality control is an important regulatory mechanism in the body to maintain nor-mal mitochondrial structure and function,mainly including mitochondrial biogenesis,mitochondrial dynamics,mitochondrial autophagy,mitochondrial oxidative stress,and other forms.The imbalance of mitochondrial quality control in chondrocytes is closely related to the occurrence and development of osteoarthritis,and regulating the balance of mi-tochondrial quality control is a potential therapeu-tic point for osteoarthritis.The author reviewed rel-evant research literature in recent years to provide a review of the relationship between mitochondrial quality control and the occurrence and develop-ment of osteoarthritis,in order to provide new ideas and directions for the research and diagnosis and treatment strategies of osteoarthritis.

The connection between tendons and bones is called the tendon bone connection. With the continuous improvement of national sports awareness, excessive exercises and the related intensity are prone to damage the tendon bone connection. Tendon bone healing is a complex repair and healing process involving multiple factors, and good tendon bone healing is a prerequisite for its physiological function. The complexity of tendon bone structure also poses great challenges to the repair of tendon bone injuries. In recent years, researches have found that stem cells, growth factors, macrophages, and other factors are closely related to the healing process of tendon bone injuries, among which macrophages play an important role in the healing process. The authors reviewed relevant research literature in recent years and summarized the role of macrophages in tendon bone healing, in order to provide new ideas and directions for treatment strategies to promote tendon bone healing.

Objective To investigate the mechanism of Shugan Zhixie Prescription in treating irritable bowel syndrome with diarrhea(IBS-D)using network pharmacology;To validate the findings through in vivo experiments.Methods Active components and potential targets of Shugan Zhixie Prescription were identified via the TCMSP database.Disease targets for IBS-D were retrieved from GeneCards,DisGeNET and OMIM databases.The intersection of drugs and disease targets was taken,and the protein interaction network was constructed by using STRING database.GO and KEGG pathways were enriched to identify the key signaling pathways of Shugan Zhixie Prescription in the treatment of IBS-D.The rat model of liver depression and spleen deficiency type IBS-D was established by the method of abnormal hunger and satiety,restraint pinch stress and intestinal perfusion of acetic acid.The rats were intervened with low-,medium-and high-dosage of Shugan Zhixie Prescription respectively for 14 days.Serum contents of diamine oxidase(DAO),interleukin(IL)-8,and IL-18 were measured by ELISA.Protein expressions and mRNA expressions of relevant targets in colonic tissue were detected using Western blot and RT-qPCR.Results A total of 26 active components and 553 targets of Shugan Zhixie Prescription were obtained,and 1 930 targets of IBS-D disease were obtained,with 184 drug-disease intersection targets.The possible mechanism was related to NF-κB,AGE-RAGE,Th17 cell differentiation and other signaling pathways.Animal experiments demonstrated that Shugan Zhixie Prescription could significantly reduce defecation frequency,fecal water content,and inflammatory cytokine levels in model rats.It markedly decreased TLR4 and NF-κB protein expressions(P<0.01),while increased AQP3,AQP8 and Occludin protein expressions in colonic tissue(P<0.01,P<0.05).Conclusion Shugan Zhixie Prescription exerts therapeutic effects on IBS-D through multiple pathways and targets,and the mechanism may be related to inhibiting TLR4/NF-κB signaling pathway and promoting intestinal barrier repair.

Nonalcoholic steatohepatitis （NASH） is a chronic liver disease with the main pathological features of hepatic steatosis， inflammatory cell infiltration， and interstitial fibroplasia， and it is an important risk factor for liver fibrosis， liver cirrhosis， and hepatocellular carcinoma. NOD-like receptor protein 3 （NLRP3） inflammasome is the core of innate immunity， and the abnormal activation of NLRP3 inflammasome is closely associated with the development and progression of NASH， which involves multiple links such as inflammatory response and oxidative stress. A large number of studies have shown that the active ingredients of traditional Chinese medicine （TCM） and TCM compound prescriptions can improve oxidative stress， regulate lipid metabolism， and alleviate liver inflammation by regulating NLRP3 inflammasome. TCM treatment applied in clinical practice has achieved a good therapeutic effect， while inflammasome is one of the key pathways or targets for TCM in improving NASH. This article reviews the mechanism of action of NLRP3 inflammasome in NASH and the research advances in TCM intervention of NLRP3 inflammasome， in order to provide ideas for the clinical TCM treatment of NASH， as well as reference targets and research directions for the research and development of new TCM drugs.

Osteoarthritis (OA) is a common chronic degenerative disease, and its condition tends to worsen with age. The pathogenesis of OA is complex, and many risk factors can lead to the occurrence of OA. Iron is one of the essential trace elements in the body, and its metabolic balance is extremely important to human health. Iron overload is closely related to the occurrence and development of OA. Excessive iron deposition in joint tissue can easily lead to lesions of articular cartilage and synovium, as well as affect subchondral bone reconstruction and lead to the occurrence of OA. The author reviewed the relevant research literature in recent years, and reviewed the mechanism of iron overload in the occurrence and development of OA, in order to provide new ideas and directions for the research and diagnosis and treatment of OA.
