Introduction: A novel type of a disposable circumcision suture device (DCSD) has been proved to be effective and safe; however, a few cases of severe bleeding took place after circumcisions.
Aim: To evaluate the effectiveness of a modified double-layer pressure dressing to avoid severe bleeding after circumcision with the DCSD, in our department in a prospective randomized controlled study, and discuss the mechanism of bleeding with DCSD.
Methods: Patients with redundant foreskin or phimosis were included between September 2018 and November 2019 and divided into 2 groups: In group A, the conventional pressure dressing was performed; in group B, an modified double-layer pressure dressing was performed.
In this study, we performed the characterization and synthesis of biocompatible and targeted albumin and graphene oxide (GO) dual-carrier paclitaxel (PTX) nanoparticles for photothermal-triggered tumor therapy. PTX absorbed on GO nanosheets as cores were coated with human serum albumin (HSA), following surface conjugation with monoclonal antibodies (mAb) against vascular endothelial growth factor (VEGF; denoted as mAbVEGF) via polyethylene glycol linker to form targeted nanoparticles (PTX-GHP-VEGF). The spherical nanoparticles were 191±5 nm in size with good stability and biocompatibility.

To realize AT effect, numerous metamaterials have been proposed, mainly based on the chirality of the structure. In this paper, we demonstrate that achiral metamaterials can also have AT effect.

Methods: A total of 172 CNBP patients and 151 healthy males were recruited as CNBP and control group, respectively.
A series of sequentially cascade-pumped random lasers is reported. It consists of three random lasers in which the Ag-Au bimetallic porous nanowires play the role of scatterers, and the gain materials are coumarin 440 (C440), coumarin 153 (C153), and rhodamine 6G (R6G), respectively. The random laser with C440 is first pumped by a 355 nm pulsed laser.

Methods: Ninety-six patients were randomly divided into two groups: 40 patients in group A treated by varicocelectomy with HBO, and 56 in group B treated by solitary varicocelectomy.
Results: The sperm density, sperm motility, sperm vigor, normality, serum testosterone, the pregnant rate of patients spouses were improved respectively in both two groups (P <0.
