Objective To evaluate efficacy of thymopentin combined with ceftriaxone on patients with early syphilis serum fixation. Methods A total of 108 patients with early syphilis serum fixation were chosen and divided into observation group and control group by the number of tables (54 cases in each group). The control group were underwent conventional sodium penicillin with benzathine with nursing treatment, the observation group were treated with ceftriaxone thymopentin combined with nursing treatment, changes in the relevant indicators before and after treatment were observed. Results After treatment, IL-2, IL-10 and other indicators in the observation group were improved compared to the control group[IL-2: the control group before treatment (20.8±4.9)μg/L, after treatment (42.7±7.3)μg/L; the observation group before treatment(19.8±5.1)μg/L, after treatment (54.6±8.3)μg/L; IL-10: the control group before treatment (76.3±16.1)μg/L, after treatment (51.3±5.4)μg/L; the observation group before treatment(78.3±4.1)μg/L, after treatment(23.8±5.1)μg/L], the differences of the two groups after treatment were statistically significant (t=3.923, 8.832, all P<0.05); after treatment, the RPR negative rates of the observation group at 3, 6, 12 months after treatment(72.2%, 85.2%, 96.3%) was significantly higher than those of the control group(53.7%, 57.4%, 63.0%), the differences were statistically significant (χ2=4.932, 11.372, 22.842, all P<0.05); the efficacy of the observation group at 3, 6, 12 months after treatment(75.9%, 79.6%, 75.9%) were significantly better than those of the control group (72.2%, 64.8%, 57.4%), the differences were statistically significant (χ2=5.232, 6.183, all P<0.05). Conclusion Thymopentin combined with ceftriaxone treatment of early syphilis can significantly improve its fixed immunological parameters, which coordinated with nursing measures can strengthen patient care awareness, then the efficacy will be better, so it is worthy of clinical further promotion.
