One nanoparticle possessing both peroxidase (POD) and catalase (CAT) activities is a prevalent co-substrate nanozyme system, distinct from the extensively researched cascade nanozyme system. During the sensing of hydrogen peroxide by POD, the impact of CAT is actually ignored in most studies. In this study, the CAT effect on hydrogen peroxide detection is thoroughly investigated based on POD catalysis by finely tuning the relative activity of POD and CAT.

In the later-line setting or for patients with PD-L1-negative tumors, immunotherapy-based regimens remain ineffective against advanced triple-negative breast cancer (TNBC). In this multicentered phase II trial (NCT04303741), 46 patients with pretreated advanced TNBC were enrolled to receive camrelizumab 200 mg (day 1), and apatinib 250 mg daily, plus eribulin 1.4 mg/m (day 1 and 8) on a 21-day cycle until progression, or unacceptable toxicity.

Ticks and tick-borne diseases pose a growing threat to human and animal health, which has brought great losses to livestock production. With the continuous expansion of human activities and the development of natural resources, there are more and more opportunities for humans to contract ticks and tick-borne pathogens. Therefore, research on ticks and tick-borne diseases is of great significance.

High-throughput screening of inhibitors from natural products is an efficient approach to target key enzymes in diabetes progression. In this study, an on-line detection system was established for the first time to rapidly screen inhibitors of α-amylase and α-glucosidase from Prunus mume. Among 28 identified compounds, 26 and 21 compounds showed strong inhibitory effect against α-amylase and α-glucosidase, respectively.

Purpose: Despite its enormous successes, the overall response rate of cancer immunotherapy remains suboptimal, especially in breast cancer. There is an increased interest in combining immune checkpoint inhibitor with targeted agents to enhance antitumor effect. Anti-angiogenic drugs have been shown to synergize with immune checkpoint blockades, but the optimal setting for combining these two modalities and the underlying mechanisms of synergistic responses are not fully understood.

An on-line high-performance liquid chromatography-diode-array-detector-electrospray ionization-ion-trap-time-of-flight-mass spectrometry-total antioxidant capacity detection (HPLC-DAD-ESI-IT-TOF-MS-TACD) system was applied for the identification and evaluation of antioxidants in Rosa chinensis Jacq., an edible flower in food industry and a widely used traditional Chinese medicine. With the help of this platform, the HPLC fingerprint, mass fragmentations, and sample activity profiles against 1,1-diphenylpicryl-2-hydrazyl radical (DPPH•) and ferric reducing antioxidant power (FRAP) were recorded after one injection.

Recent observational studies showed that breast-conserving surgery (BCS) resulted in superior survival compared to mastectomy in breast cancer patients. This study compared the clinical outcomes of BCS and mastectomy using propensity score (PS) matching analysis, which had advantages over conventional methods in reducing bias. Nonmetastatic breast cancer patients who underwent BCS and mastectomy were matched 1:1 based on their PS.

Background: Studies have recommended a 21-gene recurrence score (RS) to optimize adjuvant treatment for patients with early-stage breast cancer (EBC) with hormone receptor-positive (HR) and human epidermal growth factor receptor-2 negative (HER2) tumors. This study aimed to prospectively evaluate the impact of this RS in Chinese patients with breast cancer.

Patients And Methods: We prospectively collected 227 patients with EBC with estrogen receptor-positive (ER) and HER2 tumors.

Background: This study compared the efficacy of Sapylin and Avitene in reducing postoperative axillary seroma formation and effusion when applied topically after axillary lymphadenectomy.

Methods: A total of 224 patients were randomly divided into a Sapylin treatment group (STG), an Avitene treatment group, and a control group (CG). All patients underwent axillary lymphadenectomy and were treated during surgery with Sapylin, Avitene, or neither according to their group assignment.

Background: This study evaluated the distribution pattern of the Ki67-labeling index (LI) among patients at a Chinese breast cancer center, and analyzed its prognostic significance in the 2015 St Gallen consensus breast cancer classification, estrogen receptor-positive and human epidermal growth factor receptor 2-negative(ER/HER2)subtype.

Methods: We classified 939 women with ER/HER2 breast cancer into three groups by Ki67-LI levels, and followed their clinicopathologic characteristics and prognoses.

Results: In the 939 eligible subjects, 342 had Ki67-LI ≤10% (Ki67), 281 had Ki67-LI between 10 and 30% (Ki67), and 316 had Ki67-LI ≥30% (Ki67).

Pathologic complete response (pCR) prediction after neoadjuvant chemotherapy (NAC) is important for clinical decision-making in breast cancer. This study investigated the predictive value of Nottingham prognostic index (NPI), Immunohistochemical four (IHC4) score and a new predictive index combined with them in estrogen-positive (ER+) breast cancer following NAC. We retrospectively gathered clinical data of 739 ER+ breast cancer patients who received NAC from two cancer centers.

Background: The aim of this study was to evaluate the efficacy of vinorelbine-based regimens as first-, second- and more-line therapies in advanced breast cancer (ABC) and to analyze the best timing of vinorelbine treatment.

Methods: A total of 71 ABC patients were retrospectively reviewed. Of these, 35 patients were treated with vinorelbine-based regimens as first-line chemotherapy, and 36 patients were treated with vinorelbine-based regimens as second-line or more-line therapy.

Phosphoinositide 3-kinase enhancer (PIKE) belongs to a family of GTP-binding proteins, including three isoforms, PIKE-S, PIKE-L and PIKE-A. PIKE-S and PIKE-L interact with PI3K to enhance the activity of PI3K, but PIKE-A directly binds to AKT and up-regulates its activity. PIKEs also interacts with a variety of signaling molecules in addition to PI3K and AKT, to trigger multiple physiological functions.
