Rubber band ligation or shaobei injection for the endoscopic treatment of symptomatic hemorrhoids? A retrospective study.

Background: It is unknown whether Shaobei injection is superior to band ligation for endoscopic symptomatic hemorrhoid treatment. We compared the clinical efficacy, safety, and health economics of the two techniques.

Aims: This study aims to compare the efficacy, safety and health economics of endoscopic injection of Shaobei and endoscopic ligation in the treatment of grade I-IV symptomatic hemorrhoids.

Long noncoding RNA Gm4419 promotes mesangial cell proliferation and extracellular matrix accumulation the miR-455-3p/histone deacetylase 2 axis.

Long noncoding RNAs may function as competitive endogenous RNAs by sponging microRNAs, thereby contributing to the progression of diabetic nephropathy. In this study, a potential diabetic nephropathy-related long noncoding-microRNA-mRNA axis, Gm4419-miR-455-3p-, was predicted using bioinformatics methods. To verify the role of the Gm4419-miR-455-3p- axis in diabetic nephropathy, an high glucose-induced mesangial cell model was established.

Effects of coexisting goethite or lepidocrocite on Fe(II)-induced ferrihydrite transformation pathways and Cd speciation.

The efficacy of ferrihydrite in remediating Cd-contaminated soil is tightly regulated by Fe(II)-induced mineralogical transformations. Despite the common coexistence of iron minerals such as goethite and lepidocrocite, which can act as templates for secondary mineral formation, the impact of these minerals on Fe(II)-induced ferrihydrite transformation and the associated Cd fate have yet to be elucidated. Herein, we investigated the simultaneous evolution of secondary minerals and Cd speciation during Fe(II)-induced ferrihydrite transformation in the presence of goethite versus lepidocrocite.

Spatiotemporal variation and transport of Cs in the Beibu Gulf.

The temporal variation and transport of Cs in the Beibu Gulf (BG) are still poorly understood. Here we measured Cs concentrations in the BG water column and surface sediments during 2022. We found that Cs in the BG water column was controlled by the movement and mixing of local water masses.

De novo synthesis of hyaluronic acid with tailored molecular weights using a new hyaluronidase SthHL.

Hyaluronic acid (HA) exhibits various biological activities and functions, mainly governed by its molecular weight (M). Traditional HA degradation methods encounter challenges such as environmental pollution and high costs. Thus, developing a safe cell factory with an efficient regulation strategy for one-step production of specific M HA has attracted significant research interest.
