OBJECTIVETo investigate the impact of the regeneration of interstitial cell of Cajal (ICC) on the conduction of slow wave and gastric emptying in rats undergoing Roux-en-Y gastrojejunostomy.

METHODSTwenty male SD rats were randomly divided into experimental group and control group. The experimental group consisted of ten rats undergoing Roux-en-Y gastrojejunostomy. The control group only underwent pyloric transection and anastomosis. Gastric scintigraphy was performed in the two groups respectively to measure the half time of gastric emptying (t1/2) at sixteen weeks after the surgical manipulations, and then the myoelectrical activities near the gastrojejunal anastomosis were recorded. The study also observed the regeneration of ICC by the electron microscopy. The data of the 2 groups was compared by t test.

RESULTSIn the sixteenth postoperative week, the t1/2 was (23.5 ± 4.5) minutes for rats in the Roux-en-Y group and (10.2 ± 2.3) minutes for those in the control group, indicating delayed gastric emptying in the Roux-en-Y group (t=7.978, P=0.000), accompanied with the abnormal myoelectrical activities near the gastrojejunal anastomosis. The morphological detection showed that ICC near the gastrojejunal anastomosis regenerated and reconstructed their network in the rats of the experimental group.

CONCLUSIONThe abnormal myoelectrical activities near the gastrojejunal anastomosis, basing on the regeneration and reconstruction of ICC, may make a significant delay on the gastric emptying.

Objective:To evaluate the performance of two-dimensional fundamental sonosalpingography combined with saline infusion pelvic sonosalpingography(abbreviated as "2DFS+ SIPS" in this article) for assessing fimbrial part′s morphology and function of fallopian tubes.Methods:A total of 246 infertile women were collected from Zhejiang Provincial People′s Hospital from May 2018 to December 2019. They underwent dynamic three-dimensional harmonic sonosalpingography(abbreviated as "4DHS" in this article) first. Cases which were diagnosed as bilaterally tubal obstruction would be excluded. 2DFS+ SIPS was performed in 230 patients. Among them, 21 underwent laparoscopy and dye test(LDT) within 6 months and the results were regarded as golden standard.Results:①Tubes which were diagnosed as complete obstruction would be excluded. The total display rate of remaining fimbrial parts by using 2DFS+ SIPS and 4DHS were 77.4% and 24.0% respectively, which had statistically difference( P<0.001). ②According to 2DFS+ SIPS, fimbrial parts were classified into 3 types: normal, suspected abnormal and abnormal.Normal fimbrial parts accounted for 86.4% while suspected abnormal ones accounted for 13.6% under the condition of patency; abnormal fimbrial parts accounted for 81.2% while suspected abnormal ones accounted for 18.8% under the condition of partial obstruction. The difference in the proportion of normal and abnormal fimbrial parts according to different tubal patency was statistically significant( P<0.001). ③Fimbrial parts were classified into normal (normal fimbrial parts) and abnormal (suspected abnormal and abnormal fimbrial parts) further according to 2DFS+ SIPS, the results were compared with LDT. Accuracy, sensitivity, specificity, positive predictive value, negative predictive value and Youden′s index were 92.0%, 100%, 88.2%, 80.0%, 100%, 0.88, respectively. The consistency analysis showed the results of 2DFS+ SIPS and LDT were highly consistent (Kappa=0.828). ④All the side effects occured during the procedure or within 30 minutes after the procedure were self-limited.No serious complications were observed. Conclusions:2DFS+ SIPS is a preferred method for assessment of fimbrial part′s morphology and function, with its advantages of non-invasiveness, intuition, and accuracy. This combination could provide objective imaging basis for choosing clinical treatment strategies and predicting prognosis.
