BACKGROUND Western medicine is beneficial for the recovery of neurological function in patients with depression,but some patients experience side effects such as headaches,dizziness,nausea,gastrointestinal symptoms,insomnia,and cardiac dysfunction.In recent years,integrative medicine has achieved positive results in the treatment of various diseases.AIM To study Chuanjin Qinggan decoction combined with selective serotonin reuptake inhibitors(SSRIs)in patients with herpes zoster complicated by depression.METHODS Patients with herpes zoster complicated by depression who were treated at the Yantai Hospital of Traditional Chinese Medicine from January 2021 to December 2022 were retrospectively selected as research participants.Among them,43 patients with herpes zoster complicated by depression who received SSRI treatment between January and December 2021 were assigned to the Western medicine group,while those who received combined treatment of traditional Chinese and Western medicine between January and December 2022 were assigned to the combined group.Both groups were treated for eight weeks.The degree of pain,effect of herpes zoster treatment,degree of improvement in depressive symptoms,serum neurotransmitter levels,sleep quality,and occurrence of adverse reactions were compared between the two groups.RESULTS We found that after eight weeks of drug treatment,the two treatment schemes achieved differing efficacy.In further comparison,we found that,compared with patients treated with SSRIs alone,patients treated with Chuanjin Qinggan decoction combined with SSRIs showed more significant improvement in depression and a greater increase in dopamine and 5-hydroxytryptamine levels after treatment(P<0.05).Patients treated with Chuanjin Qinggan decoction combined with SSRIs also experienced lower pain,better treatment efficacy for herpes zoster,better sleep quality,and a lower incidence of adverse reactions compared to those treated with SSRIs alone(P<0.05).All minor adverse reactions occurring during treatment were resolv 展开更多
