Zhishi Shaoyaosan is the 34^th prescription in the Catalogue of Ancient Classic Formulas （Second Batch） published by the National Administration of Traditional Chinese Medicine in 2023. It is widely used in clinical practice and has a definite curative effect. However， there is currently a lack of its ancient literature analysis and textual research， and there is no corresponding Chinese patent medicine preparation. By consulting and combing the relevant ancient books of traditional Chinese medicine， this paper analyzes and conducts textual research of the origin， composition， measurement， administration， and efficacy of Zhishi Shaoyaosan. The results show that Zhishi Shaoyaosan is derived from Essentials from the Golden Cabinet written by Zhang Zhongjing in the Eastern Han Dynasty. It is mainly recorded in the name of Zhishi Shaoyaosan in the literature of the past dynasties. The prescription is composed of Aurantii Fructus Immaturus and Paeoniae Radix Alba. The processing method is stir-frying Aurantii Fructus Immaturus to scorch and using raw Paeoniae Radix Alba. The dose of the prescription recorded in the ancient books is mainly an equal amount of Aurantii Fructus Immaturus and Paeoniae Radix Alba in one square-cun spoon， taken three times a day， which is converted into a modern dose of 1.5 g each time （0.75 g Aurantii Fructus Immaturus and 0.75 g Paeoniae Radix Alba each time）. The components of the prescription are ground into powder and taken with barley porridge， three times a day. The efficacy is to break stagnated Qi， harmonize blood， and relieve restlessness and pain. It is mainly used to treat postpartum abdominal pain， acute pelvic inflammatory disease， acute cholecystitis and intestinal diseases， stroke sequelae， and other diseases. This study combs and analyzes the ancient literature recording Zhishi Shaoyaosan and clarifies the key information of the prescription， which provides a basis for promoting the research and development of its patent medicine.

Objective: To explore the relationship of physical activity (PA) and sedentary behavior (SB) with cardiorespiratory fitness (CRF) among middle schoold students in Tibet, so as to provide empirical references for improving the cardiorespiratory fitness and health levels of adolescents in Tibet. Methods: From August to December 2020, 1 225 junior and senior high school students were selected from 2 middle schools in Lhasa, Tibet Autonomous Region, using the stratified cluster random sampling method. Triaxial accelerometers were used to evaluate PA and SB behaviors, and the 20 meter shuttle run was employed to assess CRF among the middle school students. Isochronous substitution modeling was used to analyze the associations of SB, low intensity physical activity (LPA), and moderate vigorous physical activity (MVPA) with CRF, and the saturation threshold effect in the dose response relationship between MVPA and CRF was analyzed through restricted cubic spline and two stage linear regression. Results: After adjusting for covariates such as gender, body mass index and sleep quality score, isotemporal substitution analysis showed that among junior high school students aged 13-15, replacing 30 minutes of SB ( B =1.73) or LPA ( B =2.38) with MVPA were positively associated with CRF (both P <0.05). Among senior high school students aged 16-18, replacing SB ( B =0.99) or LPA ( B =1.38) with MVPA were also positively associated with CRF (both P <0.05). Restricted cubic spline and two piecewise linear regression analyses indicated that only middle school girls aged 13-18 exhibited a saturation threshold effect between MVPA and CRF (logarithmic likelihood ratio test=0.03), with the optimal CRF improvement observed at 60 minutes of MVPA per day ( B=0.13, P ＜ 0.01). Conclusions Reducing SB and LPA while increasing MVPA can improve CRF in Tibetan middle school students. To maximize CRF improvement, middle school girls should engage in at least 60 minutes of MVPA daily.

OBJECTIVES: To investigate the targets and mechanisms of 7-hydroxyethyl chrysin (7-HEC) in prevention and treatment of high-altitude cerebral edema (HACE) in rats. METHODS: Fifty-four male Wistar rats were randomly divided into normal control group, HACE model group, and 7-HEC-treated group (18 rats in each group). Except for the normal control group, rats in the two other groups were exposed to a hypobaric hypoxic chamber simulating a 7000 m altitude for 72 h to establish the HACE model. The 7-HEC-treated group was intraperitoneally injected with 7-HEC (150 mg·kg^－¹·d^－¹) for 3 consecutive days before modeling, while the model group received equivalent isotonic sodium chloride solution. Tandem Mass Tag (TMT) proteomics technology was used to detect differentially expressed proteins (DEPs) with screening criteria set at a fold change >1.2 and P<0.05. Western blotting was used to verify the expression levels of target proteins. Gene Ontology (GO) enrichment analysis, Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis, and protein-protein interaction (PPI) network analysis were performed. RESULTS: Compared with the normal control group, 256 DEPs were identified in the HACE model group. Compared with the HACE model group, 87 DEPs were identified in the 7-HEC-treated group. Among them, 19 DEPs that were dysregulated in the HACE model group were restored after 7-HEC intervention, of which seven (HSPA4, Arhgap20, SERT, HACL1, CCDC43, POLR3A, and PCBD1) were confirmed by Western blotting. GO enrichment analysis of the DEPs between the HACE model and 7-HEC-treated groups revealed their involvement in 13 biological processes, five cellular components, and two molecular functions. KEGG pathway analysis indicated associations with the mRNA surveillance pathway, Th17 cell differentiation, serotonergic synapse, RNA polymerase, protein processing in the endoplasmic reticulum, peroxisome, neuroactive ligand-receptor interaction, folate biosynthesis. PPI network analysis demonstrated that HSPA4, POLR3A, and HACL1, which were validated by Western blotting, interacted with multiple signaling pathways and ranked among the top 20 hub proteins by degree value, suggesting their potential role as core regulatory factors. Arhgap20, SERT and PCBD1 also exhibited interactions with several proteins, suggesting their potential as key regulatory proteins, whereas no interactions for CCDC43 were identified. CONCLUSIONS This study applied TMT proteomics to identify seven potential therapeutic targets of 7-HEC for the prevention and treatment of HACE. These targets may be involved in the pathogenesis of HACE through multiple pathways, including maintaining cellular homeostasis, ameliorating oxidative stress, regulating energy metabolism, and reducing vascular permeability.

Acute kidney injury (AKI) has high morbidity and mortality, but effective clinical drugs and management are lacking. Previous studies have suggested that macrophages play a crucial role in the inflammatory response to AKI and may serve as potential therapeutic targets. Emerging evidence has highlighted the importance of forkhead box protein O1 (FoxO1) in mediating macrophage activation and polarization in various diseases, but the specific mechanisms by which FoxO1 regulates macrophages during AKI remain unclear. The present study aimed to investigate the role of FoxO1 in macrophages in the pathogenesis of AKI. We observed a significant upregulation of FoxO1 in kidney macrophages following ischemia-reperfusion (I/R) injury. Additionally, our findings demonstrated that the administration of FoxO1 inhibitor AS1842856-encapsulated liposome (AS-Lipo), mainly acting on macrophages, effectively mitigated renal injury induced by I/R injury in mice. By generating myeloid-specific FoxO1-knockout mice, we further observed that the deficiency of FoxO1 in myeloid cells protected against I/R injury-induced AKI. Furthermore, our study provided evidence of FoxO1's pivotal role in macrophage chemotaxis, inflammation, and migration. Moreover, the impact of FoxO1 on the regulation of macrophage migration was mediated through RhoA guanine nucleotide exchange factor 1 (ARHGEF1), indicating that ARHGEF1 may serve as a potential intermediary between FoxO1 and the activity of the RhoA pathway. Consequently, our findings propose that FoxO1 plays a crucial role as a mediator and biomarker in the context of AKI. Targeting macrophage FoxO1 pharmacologically could potentially offer a promising therapeutic approach for AKI.

Objective To investigate the impact of serine/threonine-protein kinase 1(AKT1)-mediated autophagy in hepatocellular carcinoma(HCC)cells on their sensitivity to 125I seed irradiation.Methods ① iProX database and STRING12.0 website were utilized to analyze the proteomic data of HCC before and after 125I seed irradiation to explore the differentially expressed proteins and associated functional connections.Meanwhile,The Cancer Genomics Atlas(TCGA)database was employed to analyze the relationship between AKT1 expression level and the survival of HCC patients.② Human HCC cell lines HUH7 and Hep3B were exposed to continuous irradiation from 125I radioactive seeds with an initial apparent activity of 0.8 mCi per seed for approximately 120 h,accumulating a total dose of 8 Gy,while the control cells were cultured under normal condition for 120 h.③ Autophagy inhibitor,chloroquine(CQ)and inducer,rapamycin(RAPA)were used to treat the HCC cells respectively to establish the CQ group and the RAPA group.The lentiviral transfection technique was employed to construct the HCC cells with overexpressed AKT1,namely the AKT1 group.The HCC cells treated in the same way were continuously irradiated with 125I seeds for 120 h to construct the CQ+125I group,the RAPA+125I group,and the AKT1+125I group.④The changes in microtubule-associated protein light chain 3(LC3),p62,AKT1 and p-AKT1 were detected by Western blotting.Cell immunofluorescence assay was employed to observe the expression of autophagy related proteins,such as LC3.The colony forming ability and apoptotic rate were detected with plate cloning assay and flow cytometry.Results ① Continuous irradiation with 125I seeds resulted in decreased expression of p62 and increased ratio of LC3Ⅱ/LC3Ⅰ(P＜0.05)when compared with the negative control(NC)group.Immunofluorescence assay revealed more green fluorescence spots of LC3.When compared with the 125I group,the CQ+125I group had significantly increased expression of p62(P＜0.01),decreased ratio of LC3Ⅱ/LC3Ⅰ(P＜0.01),lower apoptotic rate(P＜0.01),and more colony formations(P＜0.01).In contrast,the results in the RAPA+125I group were opposite to those of the CQ+125I group.② Analysis on the iProX database showed that the expression of AKT1 was decreased in the irradiated group,and analysis on the TCGA database indicated that high expression of AKT1 predicted a poor prognosis for HCC patients(P＜0.01).③After irradiation with 125I seeds,the expression of AKT1 at both the RNA and protein levels was decreased in the 125I group(P＜0.01).After overexpression of AKT1,the level of autophagy was decreased(P＜0.05).Irradiation of HCC cells with overexpressed AKT1 using 125I seeds could partially restore the level of autophagy.In the AKT1+125I group,the expression of AKT1,pAKT1 and p62 were all decreased,and the ratio of LC3Ⅱ/LC3Ⅰwas increased than the AKT1 group(P＜0.05).④ The apoptotic rate of the AKT1+125I group was lower than that of the 125I group(P＜0.05)and higher than that in the AKT1 group(P＜0.05).In HUH7 cells,the clonogenic ability of the AKT1+125I group was higher than that of the 125I group(P＜0.05).In Hep3B cells,the clonogenic ability of the AKT1+125I group was higher than that of the 125I group,and the clonogenic ability of the AKT1 group was higher than that of the NC group(P＜0.05).Conclusion 125I seed irradiation induce lethal autophagy in HCC cells by reducing the expression of AKT1,providing a new theoretical basis for the implantation of 125I radioactive seeds in the treatment of HCC.

Objective To investigate the molecular targets and signaling pathways involved in the therapeutic effects of Lishukang Capsule(LSK)in a rat model of high-altitude pulmonary edema(HAPE)using a proteomics-based approach.Methods A total of 60 male Wistar rats were randomly assigned to a control group,a HAPE model group,3 LSK treatment groups receiving low-,medium-,and high-dose LSK,respectively,and a Rhodiola rosea(also known as Hongjitian[HJT]in pinyin,a Chinese Romanization system)control group.After HAPE modeling,the pharmacodynamic effects were assessed and the optimal LSK dose was determined using HE stains,inflammatory cytokine quantification,lung tissue water content,and the protein concentration in bronchoalveolar lavage.Label free quantitative proteomic profiling was then applied to identify differentially expressed proteins(DEPs)in the optimal dose group,using a screening threshold of over 1.5-fold change and P<0.05.The selected DEPs were validated with Western blotting,followed by Gene Ontology(GO)enrichment and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway enrichment analysis.Results The medium-dose LSK group exhibited significant anti-HAPE effects.Findings from the proteomic analysis revealed,in the comparison with the control group,267 DEPs were identified in the HAPE group.In the comparison with the HAPE group,225 DEPs were identified in the medium-dose LSK group.A total of 112 DEPs in the control group were normalized following LSK treatment in the medium-dose LSK group.In addition,GO enrichment analysis of proteins differentially expressed between the HAPE and LSK group showed that these DEPs were mainly enriched in 12 biological processes,2 cellular components,and 5 molecular functions.KEGG pathway analysis showed that LSK activated pathways associated with cell adhesion molecules,glycosaminoglycan biosynthesis,DNA replication/nucleotide excision repair,transcriptional dysregulation in cancer,and Herpes simplex virus type 1(HSV-1)infection,while inhibiting pathways associated with glycerophospholipid metabolism.Some differentially expressed proteins with potential functions were verified by Western blotting,including AGPAT5,NCAM1,SRSF3,and PLA2.These differentially expressed proteins were significantly expressed in the normal group,HAPE group,and LSK group,and the validation results were consistent with proteomic findings,indicating the high reliability of the proteomic results.Conclusion LSK exerts a significant protective effect against HAPE.Proteomic analysis suggests that its therapeutic action may be mediated through activating pathways involved in cell adhesion molecules,glycosaminoglycan biosynthesis,DNA replication/nucleotide excision repair,transcriptional dysregulation in cancer,and HSV-1 infection,alongside inhibition of pathways associated with glycerophospholipid metabolism.The key DEPs identified in these pathways may play crucial roles in the preventive and therapeutic effects of LSK on HAPE.

Objective To investigate the clinical efficacy of fasting nasogastric administration of sesame oil combined with multi-frequency vibrational abdominal massage in stroke patients with consti-pation undergoing nasogastric feeding.Methods A total of 50 stroke patients with nasogastric feeding were selected as study subjects and randomly divided into control group and study group,with 25 pa-tients in each group.The control group received routine nursing care plus multi-frequency vibrational abdominal massage,while the study group received fasting nasogastric administration of 20 mL of sesa-me oil on the basis of the control group's treatment.After 15 days of intervention,the defecation condi-tions[constipation clinical symptom score(CSS),stool consistency(Bristol stool scale),and stool volume]were compared between the two groups.Results After treatment,the CSS score in the study group was lower than that in the control group[(6.52±2.52)versus(12.64±3.32),P＜0.05].The normal stool consistency(types Ⅳ and Ⅴ on the Bristol stool scale)in the study group was higher than that in the control group(76.0％versus 8.0％,P＜0.05).The stool volume in the study group was higher than that in the control group[(303.00±93.79)g versus(196.40±60.27)g,P＜0.05].The total effective rate of defecation in the study group was 96.0％,which was higher than 32.0％in the control group(P＜0.05).The Patient Assessment of Constipation-Quality of Life(PAC-QOL)score in the study group was lower than that in the control group[(40.07±5.67)versus(63.07±7.46),P＜0.05].Conclusion Fasting nasogastric administration of sesame oil com-bined with multi-frequency vibrational abdominal massage can promote the recovery of intestinal function and improve constipation symptoms in stroke patients with nasogastric feeding.
