Vagus Nerve Preservation for Early Distal Gastric Cancer With Monitoring and Indocyanine Green Labeling: A Randomized Clinical Trial.

Importance: Radical gastric cancer surgery can cause functional and physiological disorders due to the resection of perigastric vagus nerves. Few studies have used intraoperative neurophysiological monitoring and indocyanine green (ICG) labeling to preserve the perigastric vagus nerve and to evaluate the corresponding effects.

Objective: To assess the feasibility and effects of vagus nerve preservation using neurophysiologic monitoring and ICG labeling during laparoscopic distal gastrectomy in patients with early distal gastric cancer.

A fluorescent probe for specific dual recognition of Ni and pH.

Nickel ion (Ni) and pH play an important role in environment and living organisms. A fluorescent probe "naphthalimide- s-triazine" (NCNS) for targeted dual detection of Ni and pH was synthesized. As a result, NCNS exhibits excellent optical properties: a much larger Stokes shift (140 nm), eminent changes of fluorescence intensity and significant red-shift both for Ni and pH.

A Fluorescent Probe for Hg Specific Recognition Based on Xanthene and its Application in Food Detection and Cell Imaging.

The mercury-loving unit aminothiourea was introduced into the xanthene fluorophore to synthesized the probe molecule NXH. NXH has a specific response to Hg, and with the addition of (0 ~ 50 µM) Hg, the fluorescence intensity of the probe solution was quenched from 2352 a.u.

A Dual Functional Fluorescent Probe Based on Phenothiazine for Detecting Hg and ClO and its Applications.

For the efficient detection of Hg and ClO, a double-analyte-responsive fluorescent probe PTB was successfully synthesized by combining N-butyl-3-formyl phenothiazine with hydrazine benzothiazole, and designing a specific reaction site for recognizing two analytes (Hg and ClO) in a compound. It was shown that probe PTB successfully formed a stable complex with Hg in the coordination ratio of 2:1 by using the strong sulfur affinity of Hg, which resulted in a remarkable "turn-off" effect, with a quenching efficiency of 92.5% and four reversible cycles of Hg fluorescence detection.

Two novel fluorescent probes based on quinolinone for continuous recognition of Al and ClO.

On the basis of classical Schiff base reaction, two novel and efficient fluorescent probes (DQNS, DQNS1) were designed and synthesized by introducing Schiff base structure into dis-quinolinone unit for structural modification, which can be used to detect Al and ClO. Because the power supply capacity of H is weaker than that of methoxy, DQNS shows better optical performance: a large Stokes Shift (132 nm), identify Al and ClO with high sensitivity and selectivity, low detection limit (29.8 nM and 25 nM) and fast response time (10 min and 10 s).

A fluorescent probe based on phenothiazine for detection of ClO with naked-eye color change properties.

Hypochlorite (ClO) plays a key role in life systems and it is necessary to develop an effective detection method. In view of the significant advantages of the fluorescent probe, we have synthesized a naked-eye recognition fluorescent probe NNCF for the detection of ClO based on phenothiazine and naphthalimide. The probe NNCF is sensitive (LOD = 9.

Development and validation of a preoperative nomogram for predicting the surgical difficulty of laparoscopic colectomy for right colon cancer: a retrospective analysis.

Background: In laparoscopic right hemicolectomy for right colon cancer, complete mesocolic excision is a standard procedure that involves extended lymphadenectomy and blood vessel ligation. This study aimed to establish a nomogram to facilitate evaluation of the surgical difficulty of laparoscopic right hemicolectomy based on preoperative parameters.

Materials And Methods: The preoperative clinical and computed tomography-related parameters, operative details, and postoperative outcomes were analyzed.

[Synthesis of magnetic graphene oxide modified with dodecylamine and its application for the determination of seven endocrine-disrupting chemicals in environmental water samples].

Magnetic graphene oxide (MGO) modified with dodecylamine (DDA) was synthesized in this work. The as-prepared MGO-DDA was characterized by Fourier transform infrared spectroscopy, X-ray diffraction, and vibrating sample magnetometer measurements. The material was used as the absorbent in magnetic solid-phase extraction (MSPE) for seven environmental endocrine-disrupting chemicals (EDCs):estrone (E1), -estradiol (E2), estriol (E3), 17-ethynylestradiol (EE2), hexoestrol (HEX), androstendione (AND), and bisphenol A (BPA).
