Background And Aims: Recent studies reported that non-invasive imaging techniques for measuring optic nerve sheath diameter (ONSD) offer a novel diagnostic approach for intracranial pressure (ICP) elevation. However, whether ultrasound-measured ONSD sensitively evaluate the real-time ICP is unknown. This study explores the ability of different measurement modalities to predict ICP elevation, aiming to provide a superior non-invasive ICP monitoring technique for clinical practice.

Methods: A total of 130 patients with diabetes and CKD estimated glomerular filtration rate: 30-90 mL/min/1.73m2 were enrolled and included in the analysis.

Purpose: In order to solve the problem of accurate and effective segmentation of the patient's lung computed tomography (CT) images, so as to improve the efficiency of treating lung cancer.
Method: We propose a U-Net network (DC-U-Net) fused with dilated convolution, and compare the results of segmented lung CT with DC-U-Net, Otsu and region growth. We use Intersection over Union (IOU), Dice coefficient, Precision and Recall to evaluate the performance of the three algorithms.

Purpose: Esophageal cancer is a common malignant tumor in life, which seriously affects human health. In order to reduce the work intensity of doctors and improve detection accuracy, we proposed esophageal cancer detection using deep learning. The characteristics of deep learning: association and structure, activity and experience, essence and variation, migration and application, value and evaluation.

Materials And Methods: A total of 13 patients with connective tissue disease who did not respond to prednisolone and multiple immunosuppressive agents, or their disease recurred after treatment, were given 100 mg of rituximab only combined with prednisolone once a week for 4 weeks. Then, the therapeutic effects and adverse reactions were respectively observed in the 13 patients.
Some patients have poor response to adult-onset Still disease (AOSD) traditional treatment, which easily recurs during the reduction of prednisone. We observed the efficacy and safety of tocilizumab combined with methotrexate (MTX) in the treatment of refractory AOSD, and to explore the possibility of reducing the dosage of tocilizumab after disease control.A total of 28 refractory AOSD cases who had an inadequate response to corticosteroids combined with at least 1 traditional immunosuppressive agent, and even large-dose prednisone could not relieve their conditions after recurrence, were selected in this study.

Developing fluorescent probes for selective determination of the toxic and carcinogenic hydrazine are pretty significant. Herein, a rhodamine dye coupled to naphthalene was selected as a near-infrared fluorophore and acetyl group as a trigger unit for hydrazine sensing with a Stokes shifts of 62 nm. The probe showed about 77-fold NIR fluorescence enhancement in the presence of hydrazine.

We report herein a turn-on red fluorescent xanthene-based probe (RD-Probe) for detecting thiophenol with high selectivity over other analytes including aliphatic thiols. The probe could play the part of a "naked-eye"colorimetric indicator toward thiophenol.

Objective: We aimed to investigate the association between gastric cancer and microsatellite instability (MSI) in the present study.
Method: Phenol-chloroform method was employed for DNA extraction from the cancer tissues of 65gastric cancer patients and the dysplasia tissues and normal control tissues of 32 non-gastric cancer patients. The microsatellite loci Bat25, Bat26, D2S123, D5S346 and D17S250 were detected by using PCR-SSCP silver staining technique, and the MSI of the gastric cancer tissues and the precancerous tissues was analyzed.

Objective: To investigate whether microsatellite instability (MSI) of gastric cancer and precancerous lesions were existed and its effect.
Methods: Laser microdissection was used. Gastric, intestinal metaplasia, dysplasia and normal mucosa were collected respectively.
Purpose: This study investigated the impact of early enteral nutrition (EEN) on the clinical outcomes of gastric cancer patients after radical gastrectomy.
Methods: Four hundred gastric cancer patients undergoing radical gastrectomy of any extend with D2 nodal dissection were randomly divided into an experimental and a control group with 200 cases in each group. Patients in the control group received postoperative parenteral nutrition (PN), while patients in the experimental group received postoperative EEN.
Purpose: Several studies indicated that the expression level of MLL3 gene in gastric cancer tissue was associated with prognosis, and previous studies also suggested that genetic polymorphisms of MLL3 were related to the risk for gastric cancer. The present study aimed to investigate the association of a missense mutation (S3660L) in the MLL3 gene with gastric cancer risk in a Chinese population.
Methods: In the present study, we identified a novel missense mutation in MLL3 gene (S3660L) by directly sequencing method in 48 gastric cancer patients.

It is reported that the expression level of MLL3 in gastric cancer tissue highly correlates with tumor progression. However, whether MLL3 genetic variants are associated with the risk of gastric cancer remains unclear. In this study, we conducted a genotyping analysis for MLL3 in 314 cases of gastric cancer and 322 controls from the Chinese Han population.

Background: Liver revascularization is frequently required during the enlarged radical operation for hilar cholangiocarcinoma involving the hepatic artery. Researchers have carried out a number of experiments applying partial portal vein arterialization (PVA) in clinical practice. In this study we aimed to establish a theoretical basis for clinical application of partial PVA and to investigate the effects of partial PVA on rat hilar bile duct and hepatic functions.
