Hormone receptor (HR)-positive/HER2-negative early breast cancer is the most common subtype of breast cancer, and endocrine therapy serves as the cornerstone of adjuvant treatment. In recent years, with the publication of key clinical trials such as SOFT, TEXT, and monarchE, and breakthroughs in novel agents studies like lidERA, the endocrine therapy strategy for HR-positive/HER2-negative early breast cancer has evolved toward increased precision and intensity. This article systematically reviews the latest advances in endocrine therapy, focusing on the consolidation of ovarian function suppression as a standard for high-risk premenopausal patients with updated follow-up evidence, the benefit-risk assessment of extended endocrine therapy, and the current application and interdrug differences of CDK4/6 inhibitors in the adjuvant setting. This manuscript also addresses existing challenges, including optimizing treatment-related quality of life and precisely identifying beneficiary populations, and briefly introduces the clinical trial progress of novel agents, such as oral selective estrogen receptor degraders. Furthermore, it outlines evidence-based strategies for ovarian protection during chemotherapy and fertility preservation for young patients. This review aims to provide clinicians with a comprehensive perspective, balancing the pursuit of maximal efficacy with patients′ long-term quality of life and individualized needs.

Objective: Data on syncopal donation-related vasovagal reaction (DRVR) collected from 74 blood centers between 2020 and 2023 was statistically analyzed to provide a reference for developing preventive strategies against syncopal DRVR. Methods: Data on blood donation adverse reactions and basic information of donors from 2020 to 2023 were collected through the information management system at monitoring sentinel sites. Statistical analysis was performed on the following aspects of syncopal DRVR: characteristics of donors who experienced syncope, reported incidence, triggers, duration, presence and occurrence time of syncope-related trauma, clinical management including outpatient and inpatient treatment, and severity grading. Results: From 2020 to 2023, 45 966 donation-related adverse reactions were recorded. Of these, 1 665 (3.72%) cases were syncopal DRVR. The incidence of syncopal DRVR decreased with age, being the highest in the 18-22 age group. Incidence was significantly higher in female donors than male donors, in first-time donors than repeat donors, and in university and individual donors than group donors (all P<0.05). There was no statistically significant difference among different blood donation locations (P>0.05). The top three triggers were tension, fatigue, and needle phobia or fear of blood. Among syncopal DRVR cases, 60.36% occurred during blood collection, 87.63% lasted for less than 60 seconds, and 5.05% were accompanied by trauma. Notably, 57.14% of these traumas occurred after donor had left the blood collection site. Syncope severity was graded based on required treatment: grade 1 (fully recovered without treatment, 95.50%); grade 2 (recovered after outpatient treatment, 4.02%); and grade 3 (recovered after inpatient treatment, 0.48%). Conclusion: By analyzing the data of syncopal DRVR cases, it is possible to provide a reference for formulating blood donor safety policies.

Objective To explore the effects of prohibitin 2(PHB2)on sensitivity of non-small cell lung cancer cell line A549 to erlotinib(Erl)and its potential mechanisms.Methods RACK1-specific small interfering RNA was transfected in A549 cells for knocking-down of PHB2.The effects of PHB2 inhibition on cell proliferation and apop-tosis induced by Erl were observed.The colocalization of microtuble-associated protein light chain 3 alpha(LC3)and mitochondria was visualized by MitoTracker staining and green fluorescent protein-microtuble-associated protein light chain 3 alpha(GFP-LC3)transfection.Cell proliferation was detected by 5-ethynyl-2′-deoxyuridine(EdU)staining.Cell colony formation was evaluated by colony forming assay.Apoptotic index of A549 cells was evaluated by TUNEL.Western blot was used to measure the expressions of PHB2 and LC3Ⅱ.Mitochondrial transmembrane potential,cytochrome c and respiratory chain complexⅠ/Ⅱ/Ⅴactivity were analyzed by the commercially availa-ble kits.Results Compared with the siPHB2 and siCtrl+Erl group,the EdU-positive A549 cells and the number of cell colonies decreased significantly(P＜0.05),while the TUNEL-positive A549 cells increased significantly(P＜0.05)in the siPHB2+Erl group.In addition,compared with the siPHB2 and siCtrl+Erl group,mitochondrial transmembrane potential and respiratory chain complexⅠ/Ⅱ/Ⅴactivity decreased significantly(all P＜0.05)and the levels of cytochrome c increased in mitochondrial fractions(P＜0.05)and decreased in cytosolic fractions(P＜0.05)in the siPHB2+Erl group.Conclusions PHB2 inhibition significantly improves sensitivity of A549 cells to Erl,which may be explained by inhibition of PHB2-mediated mitochondrial autophagy.

Significant research progress has been made in the development of antibody-drug conjugates (ADCs) for the treatment of ad-vanced breast cancer (ABC),ushering new hope for patients with this refractory disease. Through the conjugation of specific antibodies with highly potent cytotoxic drugs,tumor cells can be precisely targeted and killed while minimizing damage to normal tissues. ADCs such as trastuzumab-emtansine (T-DM1) and trastuzumab deruxtecan (T-DXd),have shown excellent efficacy in the treatment of HER2-positive ABC,significantly prolonging patient survival. Furthermore,ADCs targeting triple-negative breast cancer (TNBC),such as sacituzumab govitecan (SG),have also achieved positive results in clinical trials. With the continuous research,development,and optimization of ADCs,as well as the exploration of combination treatment strategies,ADCs are expected to play an increasingly important role in the treatment of ABC in the future. This article provides an overview of the research progress of ADCs in the treatment of ABC,exploring their efficacy and safety. We aim to offer more treatment options and renewed hope for patients with ABC.

Methods: The study was conducted through the literature review and two rounds of the Delphi expert consultation. The initial construction of scale dimension and item was conducted through the literature search. A survey of 12 experts from 6 different provinces, cities and regions in China was conducted, and the Delphi technique was used to collect and analyze expert opinions data about the importance and feasibility of questionnaire content. The dimensions and specific items of the questionnaire were finally determinded. Results: The response rates were 100% in both rounds of Delphi consultation. Kendall coordination degree W =0.22 ( χ 2=63.72, P <0.01), which showed the agreement of expert opinions. The initial scale consisted of 4 dimensions and 17 items, including parental cognition of school based depression screening, parental cognition of school depression screening results feedback and management, parental attitude of school based depression screening, parental utilization of mental health services. After two rounds of expert consulattion, the final scale consisted of 3 first grade dimensions including parental cognition of depression symptom, parental attitude of school based depression symptom screening and parental mental health promotion behaviour, and also cinsisted of 4 second grade dimensions including parental knowledge of depression symptom, parental attitude of school based depression symptom screening, parental choice preference of school based depression symptom screening, parental utilization of mental health services, which had a total of 25 items. Conclusion The questionnaire is developed for assessing parental acceptability of school based depression screening and associated factors. The finding will facilitate mental health services providers in the screening implementation, but further empirical research is still needed.

In order to solve the problem of high incidence of work-related musculoskeletal disorders (WMSDs) in upper limb lifting workers, a wearable auxiliary device which could be used in upper limb lifting operation was designed. The auxiliary device could be used in upper limb lifting through torsion spring device to reduce the tension of the arm muscles. The back bracket could be adjusted to adapt to the wearers of different height. The 3D model of the auxiliary device was constructed by using SoildWorks software. And the relative position and constraint between the auxiliary device and the digital simulation human were adjusted by using Jack as the main simulation tool. And then the virtual model of upper limb lifting were simulated and analyzed. Through the comparison of Rapid Upper Limb Assessment (RULA) scale, Krist comfort score and simulation results of two-handed reachable domain before and after wearing the auxiliary device, which proved that the wearable auxiliary device could reduce the risk of WMSDs in upper limb lifting workers.
