| 目的 采用胃肠超声造影定量分析高压力生活状态下大学生胃结构及动力变化。方法 纳入112名在校大学生，根据汉密尔顿焦虑量表将其中52名总分>7分者纳入高压力组、60名总分≤7分者纳入非高压力组，记录其生活、饮食习惯及相关临床表现等；比较组间胃肠超声造影中初始饱感饮入量及最大饱感饮入量的差异，测量并计算不同时间点（0~120 min）胃近端及胃远端排空率（GER）、胃动力指数及胃半排空时间（T50）等胃动力参数。结果 高压力组每天学习时间>4 h并出现失眠、食欲降低、上腹痛综合征和餐后窘迫综合征者占比均显著高于非高压力组（P均<0.05）。组间初始饱感饮入量及最大饱感饮入量差异均无统计学意义（P均>0.05）。高压力组各时间点胃近端与胃远端GER均显著低于非高压力组（P均<0.05），胃近、远端T50均大于非高压力组（P均<0.05），胃蠕动波频率、胃壁增厚率、胃蠕动波速度及胃动力指数均低于非高压力组（P均<0.05）。结论 高压力生活状态下大学生易出现胃排空延迟及胃肠运动功能减弱。 |

| Objective To observe the changes of gastric structure and motility in college students under high living pressure condition with gastrointestinal contrast enhanced ultrasound. Methods A total of 112 college students, including 52 Hamilton anxiety scale scored >7 points (high stress group) and 60 scored ≤ 7 points (non-high stress group) were enrolled, and their life, eating habits and related clinical manifestations were recorded. The initial satiety and the maximum satiety in gastrointestinal contrast enhanced ultrasonography were compared between groups, and the parameters of gastric motility, such as the proximal and distal gastric emptying rate (GER), gastric motility index and gastric half emptying time (T50) were measured and calculated at different time points (0-120 min). Results The daily learning time of high pressure group was more than 4 h, and the occurrence proportion of insomnia, decreased appetite, epigastric pain syndrome and postprandial distress syndrome in high stress group were significantly higher than those in non-high stress group (all P<0.05). There was no significant differences of initial satiety nor the maximum satiety between groups (both P>0.05). At each time point, GER of the proximal and distal stomachs in high stress group were significantly lower than those in non-high stress group (all P<0.05), while T50 of the proximal and distal stomachs in high stress group were larger than those in non-high stress group (both P<0.05), and the frequency of gastric peristaltic wave, gastric wall thickening rate, gastric peristaltic wave velocity and gastric motility index in high stress group were all lower than those in non-high stress group (all P<0.05). Conclusion College students under high living pressure condition were prone to delayed gastric emptying and decreased gastrointestinal motor function. |
