To ensure the quality of care for inpatients in ophthalmic hospitals, address the complex and variable conditions of postoperative patients, and conduct more comprehensive, accurate and real-time monitoring of patients, an intelligent monitoring system based on computer vision and artificial intelligence has been designed. This system is employed for real-time monitoring of patient health conditions and intelligent care, with primary applications in medical monitoring, rehabilitation therapy, and inpatient care. It comprises intelligent data acquisition devices, smart cameras, continuous physiological data analysis algorithms, AI algorithms, and software. Given the complex and variable conditions of postoperative patients in ophthalmic hospitals, a comprehensive, accurate, and real-time monitoring of patients is required. Therefore, it is necessary to explore a monitoring technology that imposes low physiological and psychological burdens. The intelligent monitoring system can continuously collect patients' physiological parameter indicators and transmit the monitoring data to doctors' workstations or nurse stations after analysis using intelligent algorithms, providing new tools for patient monitoring, disease assessment, risk warning, and more. Furthermore, through the application of computer vision and artificial intelligence technologies, the system can analyze facial expressions, body postures, and other data to identify patients' emotional states and bedridden postures, enabling the timely detection of abnormal situations and implementation corresponding measures. This helps improving the daily work of medical staff, enhance the nursing safety in single-patient rooms in wards, and potentially find applications in the care of critically ill patients and elderly patients, thereby improving nursing efficiency and quality.

Mechanical pain is one of the most common causes of clinical pain, but there remains a lack of effective treatment for debilitating mechanical and chronic forms of neuropathic pain. Recently, neurotoxin GsMTx4, a selective mechanosensitive (MS) channel inhibitor, has been found to be effective, while the underlying mechanism remains elusive. Here, with multiple rodent pain models, we demonstrated that a GsMTx4-based 17-residue peptide, which we call P10581, was able to reduce mechanical hyperalgesia and neuropathic pain. The analgesic effects of P10581 can be as strong as morphine but is not toxic in animal models. The anti-hyperalgesic effect of the peptide was resistant to naloxone (an μ-opioid receptor antagonist) and showed no side effects of morphine, including tolerance, motor impairment, and conditioned place preference. Pharmacological inhibition of TRPV4 by P10581 in a heterogeneous expression system, combined with the use of Trpv4 knockout mice indicates that TRPV4 channels may act as the potential target for the analgesic effect of P10581. Our study identified a potential drug for curing mechanical pain and exposed its mechanism.

Immunotherapy has become a pivotal modality in clinical cancer treatment. However, its effectiveness is limited to a small subset of patients due to the low antigenicity, impaired innate response, and various adaptive immune resistance mechanisms of the tumor microenvironment (TME). Accumulating evidence reveals the critical roles of metal elements in shaping immunity against tumor progression and metastasis. The marriage of metalloimmunotherapy and nanotechnology further presents new opportunities to optimize the physicochemical and pharmacokinetic properties of metal ions in a precise spatiotemporal control manner. Several metallodrugs have demonstrated encouraging immunotherapeutic potential in preliminary studies and are currently undergoing clinical trials at different stages, yet challenges persist in scaling up production and addressing long-term biosafety concerns. This review delineates how metal materials modulate biological activities across diverse cell types to orchestrate antitumor immunity. Moreover, it summarizes recent progress in smart drug delivery-release systems integrating metal elements, either as cargo or vehicles, to enhance antitumor immune responses. Finally, the review introduces current clinical applications of nanomedicines in metalloimmunotherapy and discusses potential challenges that impede its widespread translation into clinical practice.

Endocrine therapy is the most important adjuvant treatment for early estrogen receptor(ER)-positive breast cancer.ER-low-positive(immunohistochemistry staining 1%-10%)breast cancer has drawn widespread attention in recent years.This group accounts for 3%-9%of overall breast cancer patients.The efficacy of endocrine adjuvant therapy is relatively limited in patients with ER-low-positive breast cancer.Although the proportion of patients with low ER expression in breast cancer population is relatively low,the clinical needs of this population can not be ignored because of the large number of breast cancer patients.A number of studies have suggested that ER-low-positive breast cancer is different from ER-positive breast cancer,and is similar to ER-negative breast cancer in terms of molecular and biological characteristics,clinical features and prognosis.There are still controversies on the benefit and duration of endocrine therapy for early ER-low-positive breast cancer,and there is a lack of evidence from large-scale prospective studies.Multiple retrospective studies and meta-analyses have suggested that ER-low-positive breast cancer may have limited benefit from adjuvant endocrine therapy,and therefore endocrine therapy should be considered with caution in this population.The benefit of adjuvant therapy combined with cyclin-dependent kinase(CDK)4/6 inhibitors is yet to be supported by future data.Some patients with ER-low-positive breast cancer may try adjuvant chemotherapy in consideration of other risk factors.Additionally,clinical trials that test antibody-drug conjugates(such as sacituzumab govitecan and Dato-DXd),poly(ADP-ribose)polymerase(PARP)inhibitors,and immunotherapies for the treatment of early ER-low-positive breast cancer are still ongoing,including the phase Ⅲ ASCENT-05 study evaluating the adjuvant therapy of sacituzumab govitecan combined with pembrolizumab in high-risk human epidermal growth factor receptor 2(HER2)-negative,ER and progesterone receptor(PR)＜10%patients after surgery,the phase Ⅲ SASCIA study evaluating the adjuvant therapy of sacituzumab govitecan in high-risk HER2-negative patients after surgery,and the phase Ⅲ TROPION-Breast 04 study evaluating the neoadjuvant therapy of Dato-DXd combined with durvalumab.In addition,a neoadjuvant treatment for triple-negative breast cancer(TNBC)and ER-low expression breast cancer with olaparib and durvalumab(NCT03594396)is being explored,and the results are worth expecting.This article aimed to introduce the definition,clinical and pathological characteristics,and prognosis of ER-low breast cancer,and expound on the current treatment status and potential therapeutic strategies for HER2-negative,ER-low-positive early breast cancer in the future.
