Abstract
Triple-negative breast cancer (TNBC) causes great suffering to patients because of its heterogeneity, poor prognosis, and chemotherapy resistance. Ferroptosis is characterized by iron-dependent oxidative damage by accumulating intracellular lipid peroxides to lethal levels, and plays a vital role in the treatment of TNBC based on its intrinsic characteristics. To identify the relationship between chemotherapy resistance and ferroptosis in TNBC, we analyzed the single cell RNA-sequencing public dataset of GSE205551. It was found that the expression of Gpx4 in DOX-resistant TNBC cells was significantly higher than that in DOX-sensitive TNBC cells. Based on this finding, we hypothesize that inducing ferroptosis by inhibiting the expression of Gpx4 can reduce the resistance of TNBC to DOX and enhance the therapeutic effect of chemotherapy on TNBC. Herein, dihydroartemisinin (DHA)-loaded polyglutamic acid-stabilized Fe3O4 magnetic nanoparticles (Fe3O4-PGA-DHA) was combined with DOX-loaded polyaspartic acid-stabilized Fe3O4 magnetic nanoparticles (Fe3O4-PASP-DOX) for ferroptosis-enhanced chemotherapy of TNBC. Compared with Fe3O4-PASP-DOX, Fe3O4-PGA-DHA + Fe3O4-PASP-DOX demonstrated significantly stronger cytotoxicity against different TNBC cell lines and achieved significantly more intracellular accumulation of reactive oxygen species and lipid peroxides. Furthermore, transcriptomic analyses demonstrated that Fe3O4-PASP-DOX-induced apoptosis could be enhanced by Fe3O4-PGA-DHA-induced ferroptosis and Fe3O4-PGA-DHA + Fe3O4-PASP-DOX might trigger ferroptosis in MDA-MB-231 cells by inhibiting the PI3K/AKT/mTOR/GPX4 pathway. Fe3O4-PGA-DHA + Fe3O4-PASP-DOX showed superior anti-tumor efficacy on MDA-MB-231 tumor-bearing mice, providing great potential for improving the therapeutic effect of TNBC.

Abstract
PURPOSE To assess the effects of the preoperative application of artificial tears combined with recombinant bovine basic fibroblast growth factor on the ocular surface function and inflammatory factor levels after operation in cataract patients complicated with dry eyes. METHODS A total of 118 cataract patients (118 eyes) complicated with dry eyes treated from February 2019 to February2020 were assigned to control and observation groups (n=59 eyes/group) using a random number table. One week before the operation, the control group was administered 0.1% sodium hyaluronate eye drops (artificial tears), based on which the observation group received Beifushu eye drops (recombinant bovine basic fibroblast growth factor), both 6 times daily for 1 week. A comparison was made between the scores of clinical symptoms and the indices of ocular surface function, inflammatory factors in tears, and oxidative stress indices before and after the operation. The ocular surface function was evaluated by an ocular surface disease index questionnaire, tear film breakup-time assay, Schirmer's I test, and corneal fluorescein stain test. The inflammatory factors in tears were measured. RESULTS No significant differences were noted in the general data and clinical symptom score, ocular surface disease index, tear film breakup-time, Schirmer's I test score, fluorescein stain score, interleukin-6, tumor necrosis factor-alpha, malondialdehyde, superoxide dismutase, lipid peroxide, and total antioxidant capacity before treatment between the 2 groups (p>0.05). After treatment, the clinical symptom score, ocular surface disease index, fluorescein stain score, tumor necrosis factor-alpha, interleukin-6, malondial-dehyde and lipid peroxide declined significantly, and tear film breakup-time, Schirmer's I test score, superoxide dismutase, and total antioxidant capacity increased in both the groups. The improvements in the clinical symptom score as well as in the indices of ocular surface function, inflammatory factors, and oxidative stress were more prominent in the observation group than in the control group (p<0.05). CONCLUSIONS Artificial tears combined with recombinant bovine basic fibroblast growth factor before operation. significantly improved the ocular surface function, reduced inflammatory factors in tears, and alleviated dry eye symptoms after operation in cataract patients.

Abstract
An "antibiotic-free strategy" provides a viable option to address bacterial infections, especially for the "superbug" challenge. However, the undesirable antibacterial activity of antibiotic-free agents hinders their practical applications. In this study, we developed a combination antibacterial strategy of coupling peptide-drug therapy with chemodynamic therapy (CDT) to achieve the effective bacterial inhibition. An amphiphilic oligopeptide (LAOOH-OPA) containing a therapeutic unit of D(KLAK)2 peptide and a hydrophobic linoleic acid hydroperoxide (LAHP) was designed. The positively charged D(KLAK)2 peptide with an α-helical conformation enabled rapid binding with microbial cells via electrostatic interaction and subsequent membrane insertion to deactivate the bacterial membrane. When triggered by Fe2+, moreover, LAHP could generate singlet oxygen (1O2) to elicit lipid bilayer leakage for enhanced bacteria inhibition. In vitro assays demonstrated that the combination strategy possessed excellent antimicrobial activity not only merely toward susceptible strains (Gram-positive Staphylococcus aureus and Gram-negative Escherichia coli) but also toward methicillin-resistant Staphylococcus aureus (MRSA). On the mouse skin abscess model induced by S. aureus, self-assembled LAOOH-OPA exhibited a more significant bacteria reduction (1.4 log10 reduction) in the bioburden compared to that of the standard vancomycin (0.9 log10 reduction) without apparent systemic side effects. This combination antibacterial strategy shows great potential for effective bacterial inhibition.

Abstract
Photodynamic therapy (PDT) has become a promising candidate for cancer theranostics; however, traditional photosensitizers (PSs) usually exhibit weak fluorescence and poor reactive oxygen species (ROS) generation efficiency when aggregated. Recently, aggregation-induced emission (AIE) luminogens have shown great potential in the development of novel PSs owing to their excellent aggregation-induced ROS generation (AIG-ROS) activity. However, there are still concerns that must be addressed. In this study, two near-infrared (NIR) emitters (PI and PTI) are synthesized with AIG-ROS characteristic. PTI exhibit a valuable redder emission with more effective intersystem crossing (ISC) process than PI. The two AIE-active PSs show excellent lipid droplet (LD)-specific targeting ability. The detailed therapeutic mechanism of PDT in LDs specificity is also investigated. The mechanism of oxidation of polyunsaturated fatty acids (PUFAs) in LDs to form toxic lipid peroxides (LPOs) and thereby causing cellular ferroptosis is confirmed first. Homologous targeting is also used to achieve tumor targeting via coating PSs with active cancer cell membranes. Biomimetic aggregates exhibit good targeting ability, and an improved PDT antitumor effect via AIG-ROS activity. These findings offer a clear route to develop advanced PSs with good targeting specificity. A template has also been provided for studying the therapeutic mechanism of AIE-active PSs.

Abstract
Despite recent advances in enhancing photodynamic therapy efficacy, high-efficiency reactive oxygen species (ROS)-based therapy approach, especially in malignancy tumor treatment, remains challenging. Relieving the hypoxia of tumor tissue has been considered to be an attractive strategy for enhancing ROS-based treatment effect. Nevertheless, it is frequently neglected that the hypoxic regions are usually located deep in the tumors and therefore are usually inaccessible. To address these limitations, herein we constructed a sequential intercellular delivery system (MFLs/LAOOH@DOX) that consists of a membrane fusion liposomes (MFLs) doped with linoleic acid hydroperoxide (LAOOH) in the lipid bilayer and antitumor doxorubicin (DOX) encapsulated inside. In this report, LAOOH, one of the primary products of lipid peroxidation in vivo, was selected as ROS-generated agent herein, which depends on Fe2+ rather than oxygen and other external stimuli to produce ROS. Upon the enhanced permeation and retention effect, MFLs/LAOOH@DOX first fused with tumor cell membranes in the perivascular region in synchrony with selective delivery of LAOOH into the plasma membrane and the on-demand intracellular release of DOX. By hitchhiking with extracellular vesicles, LAOOH, as a cell membrane natural ingredient, spread gradually to neighboring cells and throughout the entire tumor eventually. Combined with subsequent administration of nano Fe3O4, ROS was specifically generated on the tumor cell membrane by LAOOH throughout the tumor tissues. This study offers a new method to enhance ROS-based antitumor treatment efficiency.

Abstract
UNLABELLED PURPOSE OF INVESTIGATIONS: The aim of this randomized controlled trial was to evaluate efficacy and tolerability of a new association of lipohydroperoxides and glycyrrhetic acid on topical treatment of bacterial and mycotic vulvovaginitis. METHODS One hundred consecutive patients with bacterial or mycotic vulvovaginitis were randomly assigned to a study group treated with vaginal lipohydroperoxides and a derivative of glycyrrhetic acid for three days (n = 50), and a control group using vaginal antibacterial metronidazole (500 mg) or antimycotic econazole (150 mg) for six days (n = 50). RESULTS A clinical and microbiological response was achieved in 80.4% and 88.9% in investigational and control group, respectively (p > 0.05). Compared to traditional antimicrobial drugs, the effect appears to be faster and safer, even if not significantly. The 6-month recurrence rate was 7.7% and 5.6% in the investigational and control group, respectively. CONCLUSION Topical medication based on lipohydroperoxides and glycyrrhetic acid showed a clinical and microbiological efficacy in the first-line treatment of bacterial and mycotic vulvovaginitis, comparable to conventional drugs.
