A nomogram of preoperative indicators predicting lymph vascular space invasion in cervical cancer.

Purpose: To develop predictive nomograms of lymph vascular space invasion (LVSI) in patients with early-stage cervical cancer.

Methods: We identified 403 patients with cervical cancer from the Affiliated Hospital of Jiangnan University from January 2015 to December 2019. Patients were divided into the training set (n = 242) and the validation set (n = 161), with patients in the training set subdivided into LVSI (+) and LVSI (-) groups according to postoperative pathology.

Efficient treatment of palladium from wastewater by acrolein cross-linked chitosan hydrogels: Adsorption, kinetics, and mechanisms.

Herein we present a study on the preparation and properties of a hydrogel adsorbent for treatment of wasted palladium souring from actial petrochemical industrial wastewater. Chitosan was used as the raw material and acrolein as the cross-linking agent for the hydrogel (A/CS). The adsorption behaviors of the hydrogel for Pd(II) ions were characterized and analyzed.

Selective adsorption and separation of methylene blue by facily preparable xanthan gum/amantadine composites.

In this work, xanthan gum-based composites were successfully graft-modified by amantadine (XG-Fe/AM) with higher adsorption capacity and selectivity on recycling cationic dye (methylene blue, MB) from aqueous solution. The adsorption equilibrium of MB could be achieved approximately within 5 min when the initial concentration was 100 mg/L, and the maximum adsorption capacity was up to 565 mg/g. After 5 desorption-regeneration cycles, the removal rate of XG-Fe/AM for MB could still be as high as 95 % with slight decrement.

Efficiently ion-enhanced adsorption of anion dyes by acrolein crosslinked polyethylenimine/chitosan hydrogel with excellent recycling stability.

A novel adsorbent acrolein crosslinked polyethylenimine/chitosan hydrogel (A-PEI/CS) was developed with excellent recycling stability and ion-enhanced effect on removing anionic dye (acid blue 93, AB93) from aquatic environment. For AB93, A-PEI/CS was such an adsorbent with the characteristics of high adsorption capacity up to 1212.4 mg/g and continuous recyle ability of more than 15 times.

Environmental determination of spring wheat yield in a climatic transition zone under global warming.

Understanding environmental determination of crop yield plays a critical role in agricultural. management in resource-limited areas. The climatic transition zone was a naturally ideal place to study.

Ondansetron combined with ST36 (Zusanli) acupuncture point injection for postoperative vomiting.

Background: Ondansetron, sometimes combined with acustimulation at PC6 (Neiguan), is commonly used for preventing postoperative nausea and vomiting, but PC6 is not the only point that can be used for this purpose.

Objectives: To evaluate the combined effects of ondansetron and ST36 (Zusanli) acupuncture point injection on postoperative vomiting (POV) after laparoscopic surgery.

Methods: A randomised, patient and assessor-blinded, placebo-controlled clinical study was conducted.
