Origin and Key Enrichment Factors of Helium Resource in the Lower Yangtze Region, Eastern China.

Helium is a critical, scarce, and strategic resource, often found in association with natural gas. This study reports the first discovery of overpressured helium-rich natural gas in the Lower Yangtze Region of Eastern China, with helium concentrations reaching as high as 4.5%, significantly surpassing the commercial extraction threshold of 0.

Comparison of the efficacy and characteristics of metallic foreign body extraction by incision surgery and x-ray guided forceps after body-surface projection positioning: A STROBE-compliant article.

A foreign body retained in soft tissue may give rise to infection and dysfunction, which may pose a potential threat to patient health. Our study is to compare the efficacy and characteristics of metallic foreign body (MFB) extraction from soft tissue by incision surgery and x-ray-guided forceps after body surface projection positioning.This study enrolled 775 patients who underwent percutaneous MFB extraction between January 2011 and December 2016.

First Direct Evidence of Pan-African Orogeny Associated with Gondwana Assembly in the Cathaysia Block of Southern China.

Metamorphic zircon from a hornblendite in the South China Block (SCB) yield U-Pb age of 533 ± 7 Ma and Hf model ages from 900 to 1200 Ma. Geochemical and isotopic characteristics indicate that primary magma of the hornblendites was probably derived from an enriched asthenospheric mantle source. This Late Neoproterozoic-Cambrian (Pan-African) metamorphic event provides the first direct evidence that the SCB was an integral part of the Gondwana assembly.

Clinical application of surface projection in the localization of metal foreign bodies using computed tomography scan.

Objective: To analyse the clinical efficacy of surface projection in the localization and removal of metal foreign bodies using CT scan.

Methods: Total 795 cases with 1008 metal foreign bodies were treated at our hospital in 2012. Pre-operative surface projection was performed to localize foreign bodies in patients under the guidance of CT scan.

Percutaneous Retrieval of Foreign Bodies Around Vital Vessels Aided with Vascular Intervention: A Technical Note.

Objective: To describe a new interventional technique to remove foreign bodies (FBs) embedded in soft tissues around vital vessels.

Methods: Under fluoroscopic guidance and using local anesthesia, percutaneous removal of FBs was performed using forceps in nine patients. All patients suffered from a metallic soft tissue FB located in close proximity to important vessels and one also had a small traumatic pseudoaneurysm adjacent to the FB.

Diversity in early crustal evolution: 4100 Ma zircons in the Cathaysia Block of southern China.

Zircons are crucial to understanding the first 500 Myr of crustal evolution of Earth. Very few zircons of this age (>4050 Ma) have been found other than from a ~300 km diameter domain of the Yilgarn Craton, Western Australia. Here we report SIMS U-Pb and O isotope ratios and trace element analyses for two ~4100 Ma detrital zircons from a Paleozoic quartzite at the Longquan area of the Cathaysia Block.

Value of 3-dimensional CT virtual anatomy imaging in complex foreign body retrieval from soft tissues.

Objective: To investigate the value of 3-dimensional (3D) CT virtual anatomy imaging (VAI) in the complex foreign body (FB) retrieval of the soft tissues.

Materials And Methods: Four hundred and seventy-five patients with radiopaque FB(s) diagnosed by radiograph underwent contrast-enhanced 3D CT examination. VAI was reconstructed by volume-rendering opacity software, by sliding down the lowest threshold from -600 to 100 HU.

Novel methods of removing metallic foreign body from human soft tissue: a report of 7390 cases.

Background: We studied methods of locating metallic foreign bodies in soft tissue of the human body.

Methods: Using a three-dimensional (3D) locator, we removed metallic foreign bodies precisely from soft tissue of 7390 patients through magnetic forceps between June 1999 and June 2009.

Results: In 7390 patients, we successfully removed 99.
