Saponins associated with Panax notoginseng (P. notoginseng) demonstrate significant therapeutic efficacy across multiple diseases. However, certain high-yield saponins face limited clinical applications due to their reduced pharmacological efficacy. This study synthesized and evaluated 36 saponin-1,2,3-triazole derivatives of ginsenosides Rg1/Rb1 and notoginsenoside R1 for anti-adipogenesis activity in vitro. The research revealed that the ginsenosides Rg1-1,2,3-triazole derivative a17 demonstrates superior adipogenesis inhibitory effects. Structure-activity relationships (SARs) analysis indicates that incorporating an amidyl-substituted 1,2,3-triazole into the saponin side chain via Click reaction enhances anti-adipogenesis activity. Additionally, several other derivatives exhibit general adipogenesis inhibition. Compound a17 demonstrated enhanced potency compared to the parent ginsenoside Rg1. Mechanistic investigations revealed that a17 exhibits dose-dependent inhibition of adipogenesis in vitro, accompanied by decreased expression of preadipocytes. Peroxisome proliferator-activated receptor γ (PPARγ), fatty acid synthase (FAS), and fatty acid binding protein 4 (FABP4) adipogenesis regulators. These findings establish the ginsenoside Rg1-1,2,3-triazole derivative a17 as a promising adipocyte differentiation inhibitor and potential therapeutic agent for obesity and associated metabolic disorders. This research provides a foundation for developing effective therapeutic approaches for various metabolic syndromes.

Postoperative stress symptoms are caused by surgical trauma,and now still lack active intervention methods to promote the recovery of body function in the field of western medicine.Professor Cai Bingqin analyzed the etiology and pathogenesis of stress symptoms after abdominal surgery,which usually manifested as abnormal sweating,sleep disorders,emotional disorders,and gastrointestinal dysfunction,and then put forward the concept of postoperative stress syndrome for the perioperative period.Professor Cai Bingqin believes that surgical stimulation,as the important etiological factor responsible for postoperative stress symptoms,can cause excessive stress in the body,which results in a series of symptoms affecting the recovery of patients.Liver plays a defensive and adaptive role in postoperative stress by regulating qi movement,blood circulation and emotions.The symptoms of abnormal sweating,sleep disorders and emotional disorders are related with the function of the liver in governing emotions,housing the ethereal soul,and ensuring the free movement of qi,while the gastrointestinal dysfunction manifestations of poor appetite,abdominal distention and constipation are due to the disharmony of liver and spleen.For the treatment of postoperative stress syndrome,Professor Cai proposes the principle of treating disease from the perspective of liver,and the methods of soothing liver and alleviating depression,and warming and activating qi movement are adopted.Sini San(Sini Powder for Soothing Liver and Regulating Qi)is commonly used as the basic prescription to ensure the normal function of liver and to ensure the free movement of qi,and then the harmony of qi and blood and the unobstruction of blood vessels will be achieved.Additionally,the assistance of therapy for invigorating spleen to dissolve dampness,and replenishing qi to consolidate superficies can adjust zang-fu organs'dysfunction,and will restore the balance of qi-blood and yin-yang.The proposal of"postoperative stress syndrome"will provide an approach to the management of perioperative period with traditional Chinese medicine,and will become the beneficial supplement to the existing fast-track surgery system.

Oncogene c-jun is a member of jun family,the immediately early genes(IEGs),and belongs to one of the nuclear transcription factors of basic leucine zipper(bZIP)family.Combined with many gene promotors,c-jun is involved in the regulation of gene transcription.Its products play important roles in regulating gene expression,cell proliferation,differentiation and apoptosis.The structure,biological funetion,regulation of c-jun and its roles contributing to tissue damage are reviewed in this article,which may provide understanding for severity of tissue injury and wound age estimation in the field of forensic pathology.
