Assessment of Helicobacter pylori infection by deep learning based on endoscopic videos in real time.

Background And Aims: Endoscopic assessment of Helicobacter pylori infection is a simple and effective method. Here, we aimed to develop a deep learning-based system named Intelligent Detection Endoscopic Assistant-Helicobacter pylori (IDEA-HP) to assess H. pylori infection by using endoscopic videos in real time.

Factors associated with non-lifting of colorectal mucosal lesions.

Background: Endoscopic submucosal dissection (ESD) is an effective treatment for colorectal tumors. However, lesions that cannot be lifted after submucosal injection are not indication for ESD. This is because the procedure is difficult, and the lesions are often considered as tumor invasion or submucosal fibrosis.

Intelligent detection endoscopic assistant: An artificial intelligence-based system for monitoring blind spots during esophagogastroduodenoscopy in real-time.

Background: Observation of the entire stomach during esophagogastroduodenoscopy (EGD) is important; however, there is a lack of effective evaluation tools.

Aims: To develop an artificial intelligence (AI)-assisted EGD system able to automatically monitor blind spots in real-time.

Methods: An AI-based system, called the Intelligent Detection Endoscopic Assistant (IDEA), was developed using a deep convolutional neural network (DCNN) and long short-term memory (LSTM).

Novel stereoselective syntheses of -octyl-β-valienamine (NOV) and -octyl-4--β-valienamine (NOEV) from (-)-shikimic acid.

-Octyl-β-valienamine (NOV) 1 and -octyl-4--β-valienamine (NOEV) 2 are potent chemical chaperone drug candidates for the therapy of lysosomal storage disorders. Novel stereoselective syntheses of NOV 1 and NOEV 2 starting from naturally abundant (-)-shikimic acid are described in this article. The common key intermediate compound 5 was first synthesized from readily available (-)-shikimic acid 9 steps in 50% yield.

Three-dimensional (3D) Printing Technology Assisted by Minimally Invasive Surgery for Pubic Rami Fractures.

The feasibility of three-dimensional (3D) printing technology combined with minimally invasive surgery in the treatment of pubic rami fractures was explored. From August 2015 to October 2017, a series of 30 patients who underwent surgical stabilization of their anterior pelvic ring (all utilizing the 3D printing technology) by one surgeon at a single hospital were studied. The minimally invasive incisions were made through anterior inferior cilia spine and pubic nodule.

Blood Pressure Associated with Arsenic Methylation and Arsenic Metabolism Caused by Chronic Exposure to Arsenic in Tube Well Water.

Objective: The effects of arsenic exposure from drinking water, arsenic metabolism, and arsenic methylation on blood pressure (BP) were observed in this study.

Methods: The BP and arsenic species of 560 participants were determined. Logistic regression analysis was applied to estimate the odds ratios of BP associated with arsenic metabolites and arsenic methylation capability.

Prevention of Esophageal Stricture After Endoscopic Submucosal Dissection: A Systematic Review.

Background: Endoscopic submucosal dissection (ESD) is rapidly becoming a favored method for removing early esophageal cancer, but the residual defects can be complicated with strictures that require repeated endoscopic balloon dilatation. Measures for preventing the post-ESD strictures have been sought. We conducted a systematic review of recent studies to evaluate these methods.

The value of endoscopic ultrasonography in defining longitudinal gross target volumes for esophageal squamous carcinoma.

Background And Purpose: To investigate the differences between endoscopic ultrasonography (EUS)-based longitudinal gross target volumes (GTV) (GTV(EUS)) and computed tomography (CT)-based longitudinal GTV (GTV(CT)) in diagnosing esophageal squamous carcinoma.

Methods: Thirty-six patients underwent EUS to define the superior and inferior extents of the tumor by using hemoclips. CT-planning scan was performed with the patient in the supine position during the treatment.

[Remediation Pb, Cd contaminated soil in lead-zinc mining areas by hydroxyapatite and potassium chloride composites].

The composite agents containing potassium chloride (KCl) and Hydroxyapatite (HA) were used to remediate the lead and cadmium contaminated soil in Fenghuang lead-zinc mining-smelting areas, Hunan province. The objective of this study was to identify and evaluate the influence of Cl- to the fixing efficiency of Pb and Cd by HA. Two types of contaminated soil (HF-1, HF-2) were chosen and forty treatments were set by five different Hydroxyapatite (HA) dosages and four different Cl- dosages.

[Relationship between longevity and soil environment in Xiayi County, Henan Province, China].

Based on field investigation and laboratory analysis, exploration was done of distribution of macro and micro elements in the soils and distribution of longevity population in Xiayi County, Henan Province, China, and relationship between the spatial variation of the distribution of soil elements and the distribution of the longevity population. It was found that longevity population was distributed in a belt running across Xiayi county from northeast to southwest. In the northeast part, the longevity rate (over 95 years old) reached 187 per million and while in the northwest part, it was only 83.

Gastric adenomyoma presenting as melena: a case report and literature review.

Gastric adenomyoma (AM) is a rare benign tumor characterized by gland-like structures embedded within a smooth muscle stroma. We report a case of a 68-year-old man with gastric AM admitted to our hospital for melana. Endoscopic examination revealed a gastric mass of about 4 cm in diameter, located in the antrum.

[Comparison of endoscopic ultrasonography with computer-assisted tomography in the determination of preoperative stage and resectability of pancreatic and ampullary cancers].

Objective: To study and compare the accuracy and sensitivity of endoscopic ultrasonography (EUS) and CT scaning in determination of preoperative stage and vascular invasion by pancreatic and ampullary cancers.

Methods: Fourty-two pancreatic cancer patients and 18 ampullary cancer patients were studied. With patients prepared according to conventional endoscopy, Olympus EUM-30 scope 1 set with a side view and 360 degrees rotate and switchable scanning probe [ultrasound frequency (7.

[Regularity of flourine release from fluorine-rich coal combustion in the fluorine poisoning area].

Laboratory experiments and in situ measurements inside farmer's houses indicate that the fluorine concentration of indoor air was positively related with the fluorine content in the consumed coal (R = 0.612, P<0.01), but fluorine content in the coal had no effect on the release rate of coal fluorine under the usual combustion temperature of about 1000 degrees C.
