A Near-Infrared II Luminogen with a Photothermal Effect toward Tumor Drug Resistance Reversal.

Multidrug resistance of tumor cells has greatly limited the chemotherapy effect. The development of reliable strategies to deal with tumor multidrug resistance is highly desirable for tumor therapy. In this work, a near-infrared II (NIR II) luminogen was rationally designed and prepared, which could act as a photothermal reagent to reverse the drug resistance of tumor cells by reducing the related protein expression, achieving a high inhibition efficiency with the synergistic effect of chemotherapeutic drugs.

Click-Reaction-Mediated Chemotherapy and Photothermal Therapy Synergistically Inhibit Breast Cancer in Mice.

The development of functional materials for tumor immunogenicity enhancement is desirable for overcoming the low therapeutic efficiency and easy metastasis during tumor treatments. Herein, the thermoresponsive nanoparticles composed of photothermal agent (PTA) and click reactive reagent are developed for enhanced immunotherapy application. A Ni-bis(dithiolene)-containing PTA with intense near-infrared absorption and efficient photothermal conversion is developed for thermoresponsive nanoparticles construction.

[Significance of urodynamic analysis in the patients with recent voiding dysfunction after radical hysterectomy].

Objective: To study the urodynamic changes in patients with recent non-infective voiding dysfunction following radical hysterectomy and assess its significance.

Methods: Ninety-six patients with cervical cancer, who were not found any abnormal representation of urodynamics before the operation, were selected into this study group. Eighty-three patients in the study group without urinary infection were detected by urodynamic examination following radical hysterectomy, in order to analyze the urodynamic reasons for the non-infective voiding dysfunction following the surgery.
