Recent research from the International Agency for Research on Cancer (IARC) of the World Health Organization (WHO) indicates that breast cancer is the most prevalent malignant tumor among women, posing a significant threat to women's health. Surgery remains the primary therapeutic modality for breast cancer. Recently, endoscopic and robotic breast surgical techniques have gained acceptance among both surgeons and patients. However, considerable variation exists in surgical approaches and outcomes. To standardize these techniques, facilitate their broader clinical adoption, and ultimately improve patient care, the Endoscopic-robotic Breast Surgery Clinical Trials Consortium (ErBSCTC) of China has developed this guideline. This document encompasses the technologies and instrumentation utilized in endoscopic and robotic breast surgery, surgical techniques, perioperative management, complication handling, long-term follow-up, and oncologic outcomes, aiming to provide evidence-based guidance for healthcare professionals involved in the prevention, diagnosis, and treatment of breast diseases.

Breast cancer is the most common malignant tumor among women in China, with surgery being one of the primary treatment modalities. Endoscopic/robotic breast surgery (ErBS) is gaining widespread acceptance among patients and surgeons alike due to its advantages of minimal invasiveness, superior cosmetic outcomes, and accelerated recovery. However, substantial heterogeneity currently exists across China regarding patient selection, standardized operative techniques, perioperative management, and complication handling, underscoring the urgent need for evidence-based consensus guidelines. To promote standardization and ensure consistent quality of ErBS, the Chinese Endoscopic-Robotic Breast Surgery Clinical Trials Consortium (CErBSCTC) has systematically reviewed the latest high-quality evidence and formulated the "Protocol for China Endoscopic and Robotic Breast Surgery Guidelines (2026 edition)", which outlines a comprehensive methodology for guideline development.

OBJECTIVE To investigate the impact of dapagliflozin on contrast-induced acute kidney injury （CIAKI） and prognosis in patients with diabetes mellitus type 2 （T2DM） and acute coronary syndrome （ACS） who underwent percutaneous coronary intervention （PCI）. METHODS Retrospective selection of data on T2DM patients with ACS who underwent PCI treatment in the Cardiology Department of Tianjin Chest Hospital from January 1st 2021 to December 31st 2022. The patients were divided into dapagliflozin group （96 cases） and control group （148 cases） based on whether they received dapagliflozin or not. Renal function indicators were measured for all enrolled patients before PCI and at 48 h and 1 week after PCI， including blood urea nitrogen （BUN）， serum creatinine （Scr）， estimated glomerular filtration rate （eGFR）， cystatin-C （Cys-C）， kidney injury molecule-1 （KIM-1） and β2-microglobulin （β2-MG）. All patients were followed up for at least 1 year. The incidence of CIAKI and major adverse cardiac event （MACE） during follow-up were recorded for both groups. Logistic regression was used to analyze the impact of dapagliflozin on the occurrence of CIAKI， while the Log-rank test was applied to compare the incidence of MACE between the two groups. Cox regression was employed to analyze the impact of dapagliflozin on prognosis. RESULTS At 48 h and 1 week after PCI， serum levels of Cys-C， KIM-1 and β2-MG were significantly lower in the dapagliflozin group compared to the control group （P＜0.05）. The incidence of CIAKI was lower in the dapagliflozin group compared to the control group （6.25% vs. 14.86%， P＝0.042）. Logistic regression analysis revealed that dapagliflozin was an independent protective factor against CIAKI （OR＝0.280， 95%CI 0.101-0.780，P＝0.015）. During the follow-up period， the incidence of MACE was lower in the dapagliflozin group compared to the control group （7.29% vs. 17.57%， P＝0.049）. Cox regression analysis indicated that dapagliflozin reduced the occurrence of MACE after PCI （HR＝0.374， 95%CI 0.161-0.866， P＝0.022）. CONCLUSIONS With adequate hydration， the use of dapagliflozin does not increase the risk of CIAKI following PCI in T2DM patients with ACS.

The liver regenerative capacity is crucial for patients with end-stage liver disease following partial hepatectomy (PHx). The specific bacteria and mechanisms regulating liver regeneration post-PHx remain unclear. This study demonstrated dynamic changes in the abundance of Parabacteroides distasonis (P. distasonis) post-PHx, correlating with hepatocyte proliferation. Treatment with live P. distasonis significantly promoted hepatocyte proliferation and liver regeneration after PHx. Targeted metabolomics revealed a significant positive correlation between P. distasonis and β-hydroxybutyric acid (BHB), as well as hyodeoxycholic acid and 3-hydroxyphenylacetic acid in the gut after PHx. Notably, treatment with BHB, but not hyodeoxycholic acid or 3-hydroxyphenylacetic acid, significantly promoted hepatocyte proliferation and liver regeneration in mice after PHx. Moreover, STAT3 inhibitor Stattic attenuated the promotive effects of BHB on cell proliferation and liver regeneration both in vitro and in vivo. Mechanistically, P. distasonis upregulated the expression of fatty acid oxidation-related proteins, and increased BHB levels in the liver, and then BHB activated the STAT3 signaling pathway to promote liver regeneration. This study, for the first time, identifies the involvement of P. distasonis and its associated metabolite BHB in promoting liver regeneration after PHx, providing new insights for considering P. distasonis and BHB as potential strategies for promoting hepatic regeneration.

Objective To analyze the relevant factors affecting self-care ability recovery in patients with acute myocardial infarction after receiving percutaneous coronary intervention(PCI).Methods A total of 108 patients with acute ST-segment elevation myocardial infarction,who underwent PCI at Lu'an People's Hospital of China from January 2021 to December 2023,were selected for this study.The patients were divided into normal group(postoperative self-care ability returning to normal,n=78)and disabled group(postoperative self-care ability being dysfunctional,n=30).The clinical data were compared between the two groups.Multiple linear regression analysis was used to analyze the factors affecting the recovery of postoperative self-care ability in patients with acute myocardial infarction after receiving PCI.Results In the disabled group,the mean age was(73.5±5.2)years,63.33％of patients lived in the countryside,Killip grade Ⅰ or above accounted for 16.67％of patients,lack of postoperative rehabilitation training accounted for 73.33％of patients,the Gensini score was(21.35±1.82)points,all of which were higher than those in the normal group(all P＜0.05).The LVEF was(47.81±8.20)％and the MNA-HF score was(20.17±3.33)points,which were lower than those in the normal group(both P＜0.05).Multiple linear regression analysis revealed that age(B=-0.171,95％CI:-0.292 to-0.049),postoperative rehabilitation training(B=-3.946,95％CI:-6.469 to-1.422),LVEF(B=0.211,95％CI:0.085-0.338),MN A-HF score(B=0.318,95％CI:0.036-0.601),and Gensini score(B=—0.907,95％CI:-2.349 to—1.465)were the factors influencing the recovery of postoperative self-care ability in patients with acute myocardial infarction after receiving PCI(P＜0.05).The regression analysis model showed:R2=0.815,adjusted R2=0.802,Durbin-Watson statistic being 1.497,F=62.827,and the fit being good(P＜0.05).Conclusion The elderly,lack of postoperative rehabilitation training,decreased LVEF level,low MNA-HF score,and high Gensini score are the factors influencing the recovery of postoperative self-care ability in patients with acute myocardial infarction after receiving PCI.In clinical practice,targeted intervention measures should be timely taken to ensure the recovery of patient's self-care ability and improve the quality of life.

This study aims to observe the effect of Panax notoginseng extracts on inflammatory re-sponse in immunosuppressed broilers and to investigate the mechanism through network pharma-cology and molecular docking combined with in vivo animal tests.Based on the TCMSP database and GeneCard and other disease databases,we searched for targets related to Panax notoginseng and broiler inflammation,screened key compounds and targets by applying Cytoscape 3.7.1 and String databases,respectively,and constructed a network relationship diagram of traditional Chi-nese medicine(TCM)-key components-targets,and carried out GO functional enrichment and KEGG pathway enrichment analyses by using the DAVID platform.The GO functional enrichment analysis and KEGG pathway enrichment analysis were carried out by the DAVID platform,visual-ized by the Chiplot online website,and finally,the core clustered proteins were analyzed by Pymol software to obtain the core targets,and molecular docking technology was used to predict the de-gree of matching between the active ingredients and the core targets as well as the animal experi-ments to further explore the pharmacological mechanism of Panax notoginseng extracts.Sixty 1-day-old red-feathered broilers were randomly divided into three groups(LPS group,CON group,and PN group),and the test period was 35 days.The LPS and PN groups were injected intraperito-neally with 250 μg/kg body weight of LPS,and the CON group was injected with an equal amount of sterile physiological saline on the 12,14,33,and 35 d.The LPS and PN groups were injected with 250 μg/kg body weight of LPS,and the CON group was injected with an equal amount of sterile physiological saline.The effect of Panax notoginseng extract on inflammatory cytokines in serum was detected by ELISA,and the hormone content in serum was also detected in each group,and fluorescence quantitative PCR was used to detect the effect of each group on the mRNA ex-pression levels of STAT3,IL-6,and CASP3.The results showed that the serum levels of IFN-γ,IL-6,iNOS,TNF-α,and TNF-β were significantly increased(P＜0.05),while the level of IL-10 was significantly decreased(P＜0.05)after LPS tapping at weeks 2 and 5.The serum levels of IFN-y,IL-6,iNOS,TNF-α,and TNF-β were significantly decreased(P＜0.05)and IL-10 was sig-nificantly increased(P＜0.05)by the addition of Panax ginseng extracts to the basal diet com-pared with the LPS group.Panax notoginseng extracts significantly decreased the serum levels of adrenocorticotropic hormone(ACTH)and corticosterone(CORT)(P＜0.05)and increased the levels of growth hormone(GH)(P＜0.05).A total of 8 active ingredients and 123 potential tar-gets for broiler inflammation were predicted by network pharmacology.The protective mechanism of Panax notoginseng against broiler inflammation may be related to the C-type lectin receptor(CLR)signaling pathway,Toll-like receptor(TLR)signaling pathway,MAPK signaling pathway,NOD-like receptor(NLR)signaling pathway,and FoxO signaling pathway.According to the pre-diction,the alleviation of inflammatory response in broiler chickens by Panax notoginseng may be related to the action on 12 key targets.Fluorescence quantitative PCR showed that Panax notogin-seng extract down-regulated the mRNA expression of IL-6 and CASP3(P＜0.05)and up-regula-ted that of STAT3(P＜0.05),and molecular docking results also showed that the active ingredi-ents in Panax notoginseng extracts could exert anti-inflammatory effects through IL-6 and CASP3.The results suggested that Panax quinquefolium extracts might alleviate the inflammatory response of immune-stressed broilers through multi-components,multi-targets,and multi-path-ways,and this study helps propose new therapeutic strategies and provides a theoretical basis for the development of feed additives based on Penthorum chinense Pursh extract.

Objective To investigate the impact of dapagliflozin on the incidence of contrast-induced nephropathy(CIN)and prognosis in elderly patients(＞60 years old)with type 2 diabetes mellitus(T2DM)undergoing percutaneous coronary intervention(PCI).Methods A retrospective study was conducted on 296 elderly T2DM patients who underwent PCI in our department from January 2021 to June 2022.With a propensity score matching at a ratio of 1∶1,according to ad-ministration of dapagliflozin or not,they were divided into a dapagliflozin group(148 cases)and a control group(148 cases).Changes in renal function,including blood urea nitrogen(BUN),serum creatinine(Cr),estimated glomerular filtration rate(eGFR),β2-microglobulin(β2-MG),cystatin C(Cys C),and neutrophil gelatinase-associated lipocalin(NGAL),were detected and calculated in both groups before and in 72 h after PCI.The incidence of CIN was recorded in the two groups,and logistic regression analysis was used to determine the effect of dapagliflozin on the occurrence of CIN.The occurrence of major adverse cardiac events(MACE)was observed in the two groups during follow-up period,and Kaplan-Meier curve analysis and Log-rank test were applied to com-pare the differences in the occurrence.Results There were no significant differences in the general clinical data between the two groups(P＞0.05).Serum levels of Cys C,β2-MG,and NGAL were increased in both groups in 72 h after PCI,with these levels obviously lower in the dapagliflozin group than the control group(P＜0.05,P＜0.01).The dapagliflozin group experienced a lower incidence of CIN than the control group(4.7％vs 12.2％,P=0.035).Logistic regression analysis indicated that dapagliflozin was an independent protective factor for CIN(OR=0.256,95％CI:0.083-0.796,P=0.019).In a follow-up period of 14.25±2.15 months,a lower incidence rate of MACE was observed in the dapagliflozin group than the control group(Log rank x2=5.257,P=0.022;HR=0.460,95％CI:0.237-0.893).Conclusion Dapagliflozin may reduce the occurrence of CIN and MACE in elderly patients with T2DM after PCI.
