Aim:
To determine the expression of c-Fos, caspase-3 and interleukin-1beta (IL-1beta) in the cervical cord and stomach of rats with cervical spondylosis, to analyze their relationship, and to offer an explanation of one possible cause for functional dyspepsia (FD) and irritable bowel syndrome (IBS) caused by cervical spondylosis.
Methods:
The cervical spondylosis model in rats was established by destroying the stability of cervical posterior column. The cord segments C4-6 and gastric antrum were collected 3 mo and 5 mo after the operation. Rats with the sham operation were used as controls. The expressions of c-Fos, caspase-3 and IL-1beta in the cervical cord and gastric antrum were determined by immunohistochemistry and/or Western blot.
Results:
Immunohistochemical staining showed a few c-Fos, caspase-3 and IL-1beta-positive cells in the cervical cord and antrum in the control. There was a significant increase in c-Fos, caspase-3 and IL-1beta expression in model groups compared to the control groups at 3 mo and 5 mo after operation. More importantly, there was a significant (P < 0.05) increase in c-Fos, caspase-3 and IL-1beta expression in the model group rats at 3 mo compared to those at 5 mo after the operation (c-Fos: 11.20 +/- 2.26 vs 27.68 +/- 4.36 in the cervical cord, 11.3 +/- 2.3 vs 29.3 +/- 4.6 in the gastric antrum; caspase-3: 33.83 +/- 3.71 vs 36.32 +/- 4.01 in the cervical cord, 13.23 +/- 3.21 vs 26.32 +/- 4.01 in the gastric antrum; IL-1beta: 42.06 +/- 2.95 vs 45.91 +/- 3.98 in the cervical cord, 26.56 +/- 2.65 vs 32.01 +/- 2.98 in the gastric antrum). Western blot analysis showed time-dependent changes of caspase-3 and IL-1beta protein in the cervical cord and gastric antrum of rats with cervical spondylosis; there was no significant expression of caspase-3 and IL-1beta protein in the control group at 3 mo and 5 mo after the sham operation, whereas there was a significant difference in caspase-3 and IL-1beta protein levels between the model group rats followed up for 3 mo and those for 5 mo (P < 0.05).
Conclusion:
There is a significant association of c-Fos, caspase-3 and IL-1beta expressions in the gastric antrum with that in the spinal cord in rats with cervical spondylosis, suggesting that the gastrointestinal function may be affected by cervical spondylosis.

Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
