Vesicoprostatic muscle reconstruction: a step further for immediate and early urinary continence.

Objectives: The vesicoprostatic muscle (VPM) is a longitudinal smooth muscle that originates from the trigone of the bladder or the opening of the ureter and is involved in urination as part of the detrusor apron. We explored the effect of VPM reconstruction on immediate and early recovery of urinary continence in patients undergoing robot-assisted laparoscopic radical prostatectomy (RALP).

Patients And Methods: A total of 523 patients with localized prostate cancer were enrolled from June 2018 to June 2020.

Phylogeny and adaptive evolution of subgenus Rhizirideum (Amaryllidaceae, Allium) based on plastid genomes.

The subgenus Rhizirideum in the genus Allium consists of 38 species worldwide and forms five sections (A. sect. Rhizomatosa, A.

Mixed Reality: A Step Further for Planning Complex Renal Tumors (RENAL Nephrometry Score of 7 or Higher).

Mixed reality (MR) technology has emerged in recent years and allows three-dimensional visualization, multiangle observation, remote vision, and virtual-real interaction. This study aims to explore the influence of MR technology on the outcomes and strategy planning of robotic surgery for complex renal tumors. A total of 92 patients with complex renal tumors were enrolled in this study from June 2018 to June 2020.

A Combined Morphological and Molecular Evolutionary Analysis of Karst-Environment Adaptation for the Genus (Ranunculaceae).

The karst environment is characterized by low soil water content, periodic water deficiency, and poor nutrient availability, which provides an ideal natural laboratory for studying the adaptive evolution of its inhabitants. However, how species adapt to such a special karst environment remains poorly understood. Here, transcriptome sequences of two species ( and ), which are Chinese endemics with karst-specific distribution, and allied species in and (living in non-karst habitat) were collected.

[Research progress in the study of brain microdialysis in glioma].

Glioma is the most common form of brain cancer. Despite recent advances in the treatment of solid tumors, there are few effective treatments for malignant gliomas due to its infiltrative nature. It has important significance to improve the treatment of glioma through in-depth understanding the intracerebral metabolic characteristics and pharmacokinetics of chemotherapeutics.

Cycloartane triterpenoids from Kleinhovia hospita.

Four new cycloartane triterpenoids, together with the known gardenolic acid B, were isolated from Kleinhovia hospita. The triterpenoids (1-3) contain a unique 21,23-diacetal side-chain, while compound 4 contains two alpha,beta-unsaturated ketone moieties. Their structures and relative configurations were determined by spectroscopic methods, including 2D NMR and IR.

[Protective effects of triterpenoids on primarily cultured rat hepatocytes injured by D-galactosamine and carbon tetrachloride].

Objective: To investigate the protective effects and mechanism of triterpenoids on primarily cultured rat hepatocytes injured by D-galactosamine (D-GalN) or carbon tetrachloride (CCl4).

Methods: Rat hepatocytes were isolated by two-step collagenase perfusion and cultured in RPMI 1640 medium. Protective effects of asiatic acid (AA) and beta-glycyrrhetinic acid (GA) were evaluated on hepatocytes injured by D-GalN (2 mmol/L) or CCl4 (10 mmol/L).

SCL-GFP transgenic zebrafish: in vivo imaging of blood and endothelial development and identification of the initial site of definitive hematopoiesis.

The bHLH transcription factor SCL plays a central role in the generation of hematopoietic cells in vertebrates. We modified a PAC containing the whole zebrafish scl locus, inserting GFP into the first coding exon of scl. In germline-transgenic zebrafish generated using this construct, GFP expression completely recapitulates the endogenous expression of scl in blood, endothelium and CNS.
