ObjectiveTo evaluate the clinical efficacy of recombinant human basic fibroblast growth factor (rh-bFGF) combined with ranitidine in the treatment of recurrent oral ulcer and its effects on serum TNF, IL-2 and T-lymphocyte subsets.MethodsThis was a retrospective study. Eighty patients with oral ulcers admitted to First Medical Center, Chinese PLA General Hospital from July 2021 to June 2022 were randomly divided into the control group and the experimental group (n=40). Patients in the control group were given topical treatment with rh-bFGF gel, while those in the experimental group were given oral treatment combined with ranitidine based on the control group, and both groups were treated continuously for 14 days. The therapeutic effect, pain relief time, ulcer healing time, as well as the differences in the levels of inflammatory factors and T-lymphocyte subsets were compared and analyzed between the two groups.ResultsThe overall response rate of the experimental group was 92.5%, while that of the control group was 75%, with a statistically significant difference(P=0.03). After treatment, inflammatory factors indexes in the experimental group were significantly lower than those in the control group, with statistically significant differences (P=0.00). The indexes of T-lymphocyte subsets in the experimental group were significantly higher than those in the control group after treatment, with statistically significant differences (P=0.00).ConclusionRecombinant human basic fibroblast growth factor combined with ranitidine is effective in the treatment of recurrent oral ulcers, boasting various benefits such as effectively promoting ulcer healing, reducing pain and inflammatory response, and enhancing immune function.Copyright: © Pakistan Journal of Medical Sciences.
