ObjectiveTo explore the mechanisms of Yangjing Tongluo prescription （YJTL） in the treatment of intrauterine adhesion （IUA） from the perspective of oxidative stress mediated by the Kelch-like ECH-associated protein 1/nuclear factor erythroid 2-related factor 2/heme oxygenase-1 （Keap1/Nrf2/HO-1） signaling pathway. MethodsA total of 48 rats with normal estrous cycles were selected and randomly divided into a normal group （n=8） and a modeling group （n=40）. An IUA rat model was established using a dual-injury method combining surgical curettage and infection. Eight rats were randomly selected from the modeling group for a pilot experiment to confirm successful model establishment. After successful modeling， the remaining 32 rats were randomly divided into a model group， a low-dose YJTL group （YJTL-L）， a high-dose YJTL group （YJTL-H）， and a Progynova group. Rats in the normal and model groups were administered purified water （15 mL·kg^-1） by gavage daily， while rats in the YJTL-L， YJTL-H， and Progynova groups received YJTL at doses of 6.43 and 12.86 g·kg^-1 and Progynova at 2.06 × 10^-4 g·kg^-1， respectively， for 14 consecutive days. The general condition， uterine morphology， and uterine index of the rats were monitored. Histopathological changes in uterine tissue were observed using hematoxylin-eosin （HE） staining. Serum levels of reactive oxygen species （ROS） and glutathione peroxidase （GSH-Px） were measured by enzyme-linked immunosorbent assay （ELISA）. Protein expression levels of Keap1， Nrf2， and HO-1 in endometrial tissue were detected by Western blot. Immunofluorescence （IF） was used to assess the distribution of Nrf2 and HO-1， as well as the expression of Nrf2 in the cytoplasm and nucleus. ResultsCompared with the normal group， rats in the model group exhibited poor mental status and reduced mobility， markedly edematous and tortuous uterine morphology， decreased gland number， and inflammatory reactions in the endometrium， along with an increased uterine organ index （P<0.05）. Serum ROS levels were significantly increased （P<0.05）， while serum GSH-Px levels were significantly decreased （P<0.05）. In endometrial tissue， Keap1 protein expression was increased （P<0.05）， whereas Nrf2 and HO-1 protein expression was decreased. Mild nuclear translocation of Nrf2 was observed， accompanied by increased relative fluorescence intensity of nuclear Nrf2 and decreased relative fluorescence intensity of cytoplasmic HO-1. Compared with the model group， all treatment groups showed varying degrees of improvement in the above symptoms and pathological changes. Serum ROS levels were reduced （P<0.05）， serum GSH-Px levels were increased （P<0.05）， Keap1 protein expression in endometrial tissue was decreased， and Nrf2 and HO-1 protein expression was increased in a dose-dependent manner （P<0.05）. Notably， significant nuclear translocation of Nrf2 was observed， with correspondingly increased relative fluorescence intensity of nuclear Nrf2 and enhanced relative fluorescence intensity of cytoplasmic HO-1. ConclusionYJTL may enhance antioxidant capacity and repair oxidative damage to the endometrial basal layer by regulating the Keap1/Nrf2/HO-1 signaling pathway.

Objective To analyze the acupoint selection rule of acupuncture and moxibustion in the treatment of gastrointestinal dysfunction associated with sepsis,thereby providing a reference for clinical treatment.Methods A systematic search was conducted in several databases,including China national knowledge infrastructure(CNKI),China Science Periodical Database,Chinese Science and Technology Journal Database,Chinese Biomedical literature database(CBM),Wanfang Data,and VIP Database,from the inception of the databases until September 30,2023.The collected literature was organized in an Excel database and subjected to descriptive analysis.Association rule analysis and cluster analysis were performed using SPSS 26.0 and SPSS Modeler 18.0 software.Results Finally,35 acupuncture and moxibustion prescriptions in 35 articles were selected for frequency statistics.The results showed 33 acupoints were used to treat gastrointestinal dysfunction in sepsis,with an overall frequency of use of 176 acupoints.The top 10 acupoints used by acupuncture and moxibustion for the treatment of gastrointestinal dysfunction in sepsis from high to low were Zusanli,Tianshu,Shangjuxu,Zhongwan,Neiguan,Xiajuxu,Guanyuan,Qihai,Shangwan,Xiawan.The top 3 were Zusanli(16.5%),Tianshu(13.6%),Shangjuxu(11.9%).The most commonly used meridians were the Foot Yangming Stomach Meridian(52.8%),Ren Meridian(23.9%),and Foot Taiyin Spleen Meridian(8.0%).The main sites for acupoint selection were the lower limbs(44.9%)and abdomen(41.5%).The most commonly used acupoints were combined acupoints below specific acupoints(35.2%),followed by recruited acupoints(27.8%).The results of high-frequency acupoint correlation analysis showed that the acupoints with the highest comprehensive support were Zusanli,Tianshu,Zhongwan,and Shangjuxu.Cluster analysis identified 5 effective clusters(Quchi acupoint-Sanyinjiao acupoint-Neiting acupoint-Daheng acupoint-Jiaji acupoint-Yinlingquan acupoint-Shangwan acupoint-Xiawan acupoint,Guanyuan acupoint-Qihai acupoint-Neiguan acupoint-Xiajuxu acupoint,Tianshu acupoint-Shangjuxu acupoint,Zhongwan acupoint,Zusanli acupoint)and 4 commonly used acupoint combinations(Guanyuan acupoint-Qihai acupoint-Neiguan acupoint-Xiajuxu acupoint,Tianshu acupoint-Shangjuxu acupoint,Zhongwan acupoint,Zusanli acupoint).Conclusions Acupuncture treatment for gastrointestinal dysfunction in sepsis is mainly based on the treatment of"spleen and stomach",with local acupoint selection and acupoint selection along the meridian as the main approach.It emphasizes the application of specific acupoints,especially the Xiahe and Mu acupoints.

Aim To study the effect of resveratrol on proliferation of liver cancer SMMC-7721 cells and the relevant mechanism.Methods SMMC-7721 cells were treated with different concentrations of resveratrol.Cell proliferation was tested by cell proliferation assay and colony-forming experiment.The effect of resveratrol on cell cycle of SMMC-7721 cells was detected by flow cytometry.The activation of mTOR/p-mTOR proteins was detected by Western blot.Results Compared with control group, resveratrol inhibited SMMC-7721 cell proliferation in a dose-dependent manner(P<0.01);cell cycle detection showed that SMMC-7721 cells were arrested at G0/G1 phase by resveratrol;Westren blot assay showed that resveratrol down-regulated p-mTOR expression.Conslusion Resveratrol inhibits human SMMC-7721 cell proliferation and arrests the cell cycle at G0/G1 phase, while the inhibition mechanism may be related to activation of mTOR signaling pathway by resveratrol.
