简介：AbstractBackground:Gastroparesis is a debilitating medical condition with limited treatment options. Gastric per-oral pyloromyotomy (G-POEM) has emerged as a promising treatment option with remarkable short-term clinical success shown in multiple studies. While the post-procedure protocol is not standardized across many centers, the majority of the centers observes these patients in the hospital after the procedure for monitoring. In this single-center prospective study, we evaluated the safety and feasibility of same day discharge after the G-POEM procedure.Methods:All the patients with refractory gastroparesis undergoing G-POEM from October 2019 to March 2020 were enrolled. A total of 25 patients were enrolled in the procedure. Based on the pre-defined criteria, patients were either discharged on the same day after the procedure or admitted to the hospital for further observation. The patient and procedure-related data were extracted from the chart review. Univariate analysis was performed (chi-squared test) on categorical variables after organizing categorical variables as numeric counts or percentages. The student t test was performed on continuous variables after reporting as mean and standard deviation. For analysis with a smaller sample size, Fisher exact and Mann–Whitney tests were used.Results:A total of 25 patients were enrolled. The technical success of G-POEM was 100% and clinical success was 80% (20/25) at 1-month follow-up. Of the 25 patients, 9 patients (36%) were discharged on the same day according to the procedure from the recovery unit. Of the remaining 16 patients who were admitted to the hospital post-procedure, 10 (40%) were admitted due to procedure-related causes while other admissions were either pre-planned or due to social reasons. The average Charlson comorbidity index was lower in the same day discharge group (P < 0.05). The number of patients requiring double myotomy was higher in the same day discharge group (P < 0.05). The overall complication rate of G-POEM in the study cohort was 12% (3/25) with all complications being mild without any severe adverse events.Conclusion:G-POEM is a safe and effective method of treatment for refractory GP with higher clinical success in short-term follow-up. The same day discharge after G-POEM is safe and feasible in >50% of patients with close periprocedural monitoring.

简介：目的：研究左旋精氨酸对大鼠胰腺腺泡细胞（AR42J）节律基因Per1表达的影响。方法：采用12-十四酸佛波酯-13-乙酸盐诱导AR42J细胞节律基因表达。在Per1RNA表达出现稳定近日节律后,设置实验组与对照组,实验组中加入含L-Arg培养液,对照组加入等量不含L-Arg培养液,采用RT-PCR法检测不同时间点AR42J细胞中Per1RNA的表达水平。结果：RT-PCR结果显示加入L-Arg实验组的Per1RNA表达量比对照组明显降低（P〈0.05）。结论：L-Arg可引起胰腺腺泡细胞中的Per1RNA表达降低,提示氨基酸可影响节律基因的表达。
