Application value of continuous nursing in the treatment of obese patients with laparoscopic sleeve gastrectomy.

Aim: To explore the value and effectiveness of continuous nursing in obese patients undergoing laparoscopic sleeve gastrectomy.

Methods: A total of 164 obese patients who were admitted to Nanjing Drum Tower Hospital and underwent planned laparoscopic sleeve gastrectomy in 2022 were retrospectively selected as the control group, and another 164 obese patients undergoing the same surgery in 2022 were chosen as the research group. The control group received routine care, while the research group received continuous nursing care.

The Effect of immunonutrition in patients undergoing pancreaticoduodenectomy: a systematic review and meta-analysis.

Background: Pancreaticoduodenectomy (PD) is a complex and traumatic abdominal surgery with a high risk of postoperative complications. Nutritional support, including immunonutrition (IMN) with added glutamine, arginine, and ω-3 polyunsaturated fatty acids, can improve patients' prognosis by regulating postoperative inflammatory response. However, the effects of IMN on PD patients' outcomes require further investigation.

Effect of pH, temperature and Cl- concentration on electrochemical behavior of NiTi shape memory alloy in artificial saliva.

The cooperation of pH, temperature and Cl- concentration on electrochemical behavior of NiTi shape memory alloy in artificial saliva was studied using orthogonal test method. The results showed that the pitting potential for NiTi in artificial saliva decreased at low and high pH; at 25 degrees C, the pitting potential was the lowest compared to those at 10 degrees C, 37 degrees C and 50 degrees C; when the Cl- concentration was not less than 0.05 mol/L the pitting potential decreased with the increase of Cl- concentration.

Stress corrosion cracking of NiTi in artificial saliva.

Objectives: This paper aimed to study the mechanism of the cracking of orthodontic NiTi wire.

Methods: Two orthodontic NiTi wires were subjected: (1) optical and scanning electron microscopy (SEM) to observe the fracture surface; (2) energy dispersive X-ray spectroscopy to determine the composition of the surface product; (3) anodic polarization to remove the surface product. Samples of NiTi alloy were subjected to the constant loading test to study the stress corrosion cracking (SCC) behavior of NiTi shape memory alloy in artificial saliva.
