The predictive value of hunger score on gastric evacuation after oral intake of carbohydrate solution.

Background: Surgical patients are asked to fast for a sufficient duration to ensure that the amount of residual liquid in the stomach is within the safe range, thereby reducing the risk of gastric reflux perioperatively. The authors hypothesized that subjective hunger numerical rating scale (NRS) score could also help assess the process of gastric emptying and determine the amount of fluid remaining in the stomach.

Methods: The current study consisted of healthy volunteers recruited by advertisement and mutual introduction.

[Clinical significance and expression of fatty acid synthase mRNA in lung cancer].

Background: Fatty acid synthase (FAS) is differentially overexpressed and hyperactivated in many tumors and indicates poor prognosis. The aim of this study is to explore the expression of FAS mRNA and its significance in lung cancer tissues and paracancerous tissues, compared with normal lung tissues.

Methods: Fifty-five lung cancer tissues, 32 paracancerous tissues and 32 normal lung tissues were collected.
