180 iron nails and other foreign objects, including coins, screws, nuts and magnets have recently been removed by doctors at a hospital in Southwest China’s Yunnan Province from a local man’s stomach after he sought treatment for repeated vomiting and abdominal pain, Yunnan Daily reported on Sunday.
The man’s family took him to The Third People’s Hospital of Yunnan Province for examination. Imaging scans revealed a large mass of metal objects in the man’s abdomen, which had clumped together, distended his stomach and caused it to drop downward, according to the report.
The nearly three-hour surgery on Friday removed foreign objects weighing more than 1 kilogram, including a nail nearly 10 centimeters long.
According to Li Wei, chief physician from the hepatobiliary and pancreatic surgery department at the hospital, the patient’s stomach was covered with ulcers and erosions, but fortunately the nails did not perforate the stomach or enter the intestines. The magnets may have caused the nails to clump together, with some nails becoming magnetized. The patient is recovering well and remains in stable condition.
Doctors at the hospital have previously treated patients who swallowed nails, wires and lighters, but this was their first case involving 180 nails.
The man’s family members told Jimu News, a news portal under Hubei Daily, that he had a long history of mental illness and nobody knew why he swallowed so many nails.
Li warns that people should not assume that small swallowed objects will pass on their own, particularly when they are metal or sharp. Such objects can become lodged in narrow sections of the digestive tract and cause injuries or perforation, potentially leading to peritonitis and life-threatening complications.

The core castings for the world's most powerful onshore wind turbine in terms of single‑unit capacity have recently been delivered by a Chinese company, marking a technological breakthrough in the large‑megawatt onshore wind power castings, domestic news portal stdaily.com affiliated with Science and Technology Daily reported on Wednesday.
Independently developed by Dalian Huarui Heavy Industry Group Co., Ltd. (DHHI), the delivered components include the bearing housing and base castings for 15 MW doubly fed onshore wind turbines. The components need to bear the huge gravity, wind loads and alternating loads transmitted from the blades and hub, and transfer the loads to the generator, ensuring steady rotation of the main shaft.
The products passed all customer inspections and assessments in one go and were officially delivery, stdaily.com reported.
Adopting an advanced modular design, the turbine components delivered can support flexible power adjustment ranging from 13 MW to 16 MW, enabling adaptive operation to varying and complex wind conditions across diverse regions, the report said.
The turbine's rotor diameter ranges from 240 meters to 260 meters, and are compatible with tower heights of 135 meters to 190 meters, delivering a maximum swept area of 53,000 square meters, roughly 8 standard football pitchs (105m×68m). This places the unit's overall performance among the world's top-tier.
Such super-large castings place extremely high demand on material properties, casting processes, dimensional accuracy and internal quality. The successful validation and delivery of the products therefore demonstrate the research and development, as well as manufacturing capabilities in super‑large wind power castings, stdaily.com reported.
