Objective:To investigate the effect of chrysophanol(CHR)on cartilage injury in rats with osteoarthritis and its mechanism of regulating SIRT1/HMGB1/NF-κB signal pathway.Methods:Rat models of osteoarthritis were established and divided into negative control group,chrysophanol low(CHR-L,10 mg/kg),middle(CHR-M,20 mg/kg),high dose group(CHR-H,40 mg/kg),SIRT1 inhibitor(sirtinol 5 mg/kg)+chrysophanol high dose group(sirtinol+CHR-H),and normal healthy control group was set up.The degree of joint swelling was measured,and the inflammatory index was evaluated;the pain threshold(tenderness and heat pain)was measured;HE staining and safranine O staining were applied to detect the pathological changes of rat articular cartilage;the levels of serum inflammatory factors(IL-6,IL-1β,TNF-α)were detected by ELISA method;oxidative stress indexes(MDA,SOD,GSH-PX)were detected by micro method;TUNEL staining was used to detect apoptosis;Western blot was used to detect the protein expressions of SIRT1,HMGB1,NF-κB p65,p-NF-κB p65,MMP-13 and C-Caspase-3.Results:Compared with the normal healthy control group,the rats in negative control group had obvious pathological injury,such as destruction of articular cartilage structure,necrosis and reduction of chondrocytes,the joint swelling degree,arthritis index,levels of IL-6,IL-1β,TNF-α,content of MDA,chondrocyte apoptosis rate,expressions of apoptotic protein C-Caspase-3,HMGB1,NF-κB p65/p-NF-κB p65,MMP-13 proteins increased obviously,the tenderness threshold,heat pain threshold,activities of SOD,GSH-PX,and the expression of SIRT1 protein decreased obviously(P<0.05);compared with negative control group,the pathological injury of articular cartilage in CHR group improved obviously with the increase of dosage,the joint swelling degree,arthritis index,levels of IL-6,IL-1β,TNF-α,content of MDA,chondrocyte apoptosis rate,expression of apoptotic protein C-Caspase-3,HMGB1,NF-κB p65/p-NF-κB p65,MMP-13 proteins decreased obviously,the tenderness threshold,heat pain threshold,activities of SOD,GSH-PX,and the expression of SIRT1 protein increased obviously(P<0.05);compared with CHR-H group,sirtinol+CHR-H group was able to reverse the protective effect of CHR on cartilage injury to a certain extent.Conclusion:CHR can reduce the inflammation of articular cartilage,inhibit the apoptosis of chondrocytes and play a protective role in the cartilage injury of osteoarthritis rats by up-regulating the expression of SIRT1 and down-regulating the expressions of HMGB1 and NF-κB p65/p-NF-κB p65.

[Objective]To explore the issues in the"14th Five-Year Plan"textbook Formulology and propose corrective suggestions,aiming to deepen students'understanding of formulology knowledge and contribute to the cultivation of high-quality and versatile talents in traditional Chinese medicine(TCM).[Methods]Through consulting the ancient books and literatures,the source research of the prescriptions involved in the teaching materials was carried out.Combined with clinical practice and TCM theory,the indications and functions of the formulas were analyzed to ensure the descriptions accurate and clinically significant.The explanation of formula composition was deepened from the perspectives of compatibility principles and drug interactions.The accuracy and logic of formula mnemonics(Fangge)were optimized.Ideological and political elements were skillfully integrated to cultivate students'medical ethics,professional and social responsibility.Suggestions were also made to address improper layout issues.[Results]The textbook was rich in content and systematic in structure,but minor issues remain in areas such as formula origins,indications and functions,formula explanation,formula mnemonics,ideological integration and layout.Through literature review,the origins of formulas such as Xijiao Dihuang Decoction,Sijunzi Decoction and Ganlu Xiaodu Pill were researched deeply,and the source information was corrected.The indications and functions of formulas like Houpo Wenzhong Decoction,Wumei Pill,and Suzi Jiangqi Decoction were reanalyzed,enhancing their clinical relevance.The new explanation of Daochi Powder,Shenqi Pill,Zhengan Xifeng Decoction,Sanren Decoction,Lianpo Decoction and Dahuang Mudan Decoction was introduced to enhance students'understanding of the principles of prescription compatibility and clinical application.The mnemonics for formulas like Puji Xiaodu Drink and Sanzi Yangqin Decoction were revised for greater accuracy and logic.Innovative ways of integrating ideological and political elements were adopted,which complemented formulary knowledge and promote the improvement of students'comprehensive quality.For layout issues,such as the misplaced"Application"section of Qingqi Huatan Pill,a comprehensive proofreading was recommended to ensure proper placement and coherence of all sections.[Conclusion]By exploring specific issues in the Formulology textbook under the"14th Five-Year Plan"—including formula origins,indications and functions,formula explanation,formula mnemonics,ideological and political education integration,and layout—and proposing targeted revisions,this initiative enhances the textbook's academic rigor and practicality.It provides high-quality educational resources for TCM education,thereby fostering the cultivation of well-rounded TCM professionals with solid theoretical foundations,specialized skills and comprehensive quality.

Objective To investigate the value of endoscopic ultrasonography(EUS)in the diagnosis and treatment of undetermined etiology of common bile duct (CBD) dilatation. Methods Patients, who were referred for dilated CBD but unable to identify the cause by imaging, underwent EUS for the diagnosis of etiology in Endoscopy Center of Zhongshan Hospital Affiliated to Fudan University from December 2015 to December 2016. The therapy was on the basis of diagnosis of EUS. Final diagnoses were determined by surgical pathology or follow-up for at least 3 months. Results A total of 76 patients were included in the study. The sensitivity, specificity and accuracy of EUS for patients with choledocholithiasis,patients with ampullary tumor, and patients with inflammatory stenosis were 100.0%(7/7), 100.0%(69/69), 100.0%(76/76), and 88.0%(22/25), 92.2%(47/51), 90.8%(69/76),and 90.9%(40/44), 93.8%(29/32), 90.8%(69/76), respectively. Accuracy of EUS for etiological diagnosis of CBD dilatation was 90.8%(69/76). The sensitivity,specificity and accuracy of EUS combined with tumor markers for patients with malignant CBD dilatation were 96.0%(24/25), 96.1%(49/51),and 96.1%(73/76), respectively. Conclusion EUS is an effective method for the etiological diagnosis of CBD dilatation and has guiding significance for the treatment. EUS combined with tumor markers may benefit differential diagnosis of benign and malignant CBD dilatation.
