Abstract:Objective To investigate the efficacy of citicoline sodium capsule combined with urinary kallidinogenase in the treatment of acute cerebral infarction (ACI) and its impact on serum levels of homocysteine (Hcy) and C-reactive protein (CRP).Methods A total of 120 ACI patients admitted to our hospital from January 2020 to January 2023 were selected and randomly divided into an observation group and a control group using the random number table method, with 60 patients in each group. Both groups were given routine treatment, and the control group was given urinary kallidinogenase while the observation group was subject to combined citicoline sodium capsule and urinary kallidinogenase. The clinical efficacy was compared between the two groups. The patients were evaluated with the National Institutes of Health Stroke Scale (NIHSS) and Activity of Daily Living Scale (ADL). The parameters of the cerebral vessels and serum levels of Hcy and CRP levels were measured in both groups. Finally, the incidence of adverse events was observed and analyzed in both groups.Results The overall effective rate of the observation group was higher than that of the control group (P < 0.05). The difference of the NIHSS scores before and after the treatment in the observation group was lower than that in the control group (P < 0.05), while the difference of the ADL scores before and after the treatment in the observation group was higher than that in the control group (P < 0.05). The decreases in cerebral blood flow velocity, cerebral blood flow and cerebral blood volume in the observation group before and after the treatment were greater than those in the control group (P < 0.05). The differences of the serum levels of Hcy and CRP before and after the treatment in the observation group were higher than those in the control group (P < 0.05). There was no statistically significant difference in the overall incidence of adverse reactions between the observation group and the control group (P < 0.05).Conclusions The combination of citicoline sodium capsule and urinary kallidinogenase has significant clinical efficacy in the treatment of ACI. It effectively improves neurological deficits and activities of daily living of patients, and significantly increases the cerebral blood flow velocity, cerebral blood flow and cerebral blood volume as well as the serum levels of Hcy and CRP with few safety concerns.
