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.

This guideline, presented in three parts, details the core aspects of endoscopic/robotic breast surgery, including its techniques, equipment, surgical procedures, perioperative management, complication treatment, long-term follow-up, and outcomes. Part one offered a comprehensive overview of indications for endoscopic and robotic breast surgery, intraoperative techniques, surgical instrument choices, and common endoscopic and robotic breast reconstruction procedures. This part will cover other endoscopic breast procedures beyond immediate breast reconstruction and include perioperative management strategies, to provide healthcare professionals involved in endoscopic and robotic breast surgery with systematic operational guidelines and clinical decision-making references.

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.

It was a retrospective study. The propensity score matching was applied to divide the type 2 diabetes mellitus (T2DM) patients who have underwent percutaneous coronary intervention (PCI) into two groups: short-term (<4 weeks) sodium-glucose cotransporter 2 inhibitor (SGLT2i) group (213 patients) and control group (213 patients). The occurrence of contrast-induced acute kidney injury (CIAKI) after PCI was compared between the two groups. The results showed that the incidence of CIAKI in the SGLT2i group was not significantly different from the control group [10.8% (23/213) vs. 7.5% (16/213), χ2=1.383, P=0.313]. The incidence of CIAKI in patients with SGLT2i application time <1 week was higher than that in control patients, but the difference was not statistically significant [13.00% (16/123) vs. 7.5% (16/213), χ2=2.734, P=0.122]. Multivariate logistic regression analysis showed that short-term (<4 weeks) use of SGLT2i would not increase the risk of CIAKI after PCI in T2DM patients ( OR=0.507, 95% CI 0.238-1.077, P=0.077). Short-term application of SGLT2i before PCI may not increase the risk of CIAKI, but it is advisable to avoid initiating the application of SGLT2i before PCI as much as possible.

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.

Danggui Buxue decoction(DBD)is a classic prescription with immunomodulatory and hematopoietic effects.Previous studies have shown the DBD has potential to be used as an oral im-mune booster.However,its immunomodulatory effects and mechanism of action have not been thoroughly studied,especially the protective mechanism of immunomodulatory regulation in the state of immunosuppressive is still unclear.The aim of this study was to explore the protective mechanism of DBD in the immunosuppressive state using network pharmacology combined with animal experiments verification.The active components,core targets and signaling pathways of DBD in treating immunosuppression were obtained using network pharmacology tools.On this ba-sis,the active components of DBD were identified using HPLC-MS,and in vivo studies were con-ducted at the same time.The key active components of DBD obtained using network pharmacology included quercetin,kaempferol and formononetin.The core targets included TP53,RELA,TNF,AKT1,and IL-6.KEGG pathway enrichment analysis showed that phosphoinositide 3-kinase(PI3K)-protein kinase B(AKT)may play an important role in the treatment of immunosuppres-sive diseases using DBD.Molecular docking confirmed that each core target had good binding activ-ity with its corresponding compounds.Animal experiments showed that after DBD intervention,the mRNA gene and protein expression of RELA,TNF,and IL-6 in the serum was significantly down-regulated.The mRNA expression of PI3K and AKT in the ileum and PI3K protein expression were also downregulated.In conclusion,DBD exerts its role in treating immunosuppressive diseases by regulating the PI3K-AKT signaling pathway.

This study was aimed at predicting and analyzing the structural and functional properties of the persistence-associated secretory protein PaaX in Mycobacterium tuberculosis(M.tb),identifying its interacting partners,and elucidating its biological roles.Bioinformatics analysis revealed that PaaX comprises 240 amino acids with a molecular mass of 26.54 kDa(C1158H1866N354O334S14).The protein lacks transmembrane domains but contains a signal peptide.Its secondary structure is dominated by α-helices(53.33%),fol-lowed by random coils(36.25%)and extended strands(10.42%),thereby forming a homotetrameric spatial configuration.Potential PaaX-interacting proteins,including Rv0406c,EchA4,EchA5,HsaE,FadE8,LpqP,and End,were predicted.These candidate genes and the paaX gene were cloned into bacterial two-hybrid vectors and co-transformed into Escherichia coli BTH101 cells.Colony PCR and sequencing confirmed the accuracy of the recombinant constructs.Bacterial two-hybrid assays demonstrated direct interac-tions of PaaX with EchA4,HsaE,FadE8,and LpqP.Moreover,gradient dilution experiments indicated that the strongest binding af-finity occurred between PaaX and EchA4.AlphaFold 3 modeling further validated these interactions,thus providing high-confidence predictions of binding interfaces.Our findings revealed that PaaX,a secreted α-helix-rich protein,engages in specific interactions with key metabolic enzymes(EchA4,HsaE,and FadE8)and a lipoprotein(LpqP),thus suggesting its potential involvement in lipid metabolism,stress adaptation,and host-pathogen interactions.This study provides novel insights into PaaX's contribution to M.tb per-sistence and pathogenicity,and highlights its value as a potential target for tuberculosis diagnostics and therapeutic development.
