[Objective]To explore the phenomenon and regularity of acupoint sensitization for major depressive disorder(MDD)based on bibliometric methodology and data mining technology,and to provide scientific ideas for the clinical diagnosis and treatment of MDD.[Methods]Eight electronic databases and one ancient book were comprehensively searched and available literature was retrieved.Bibliometric methodology and data mining technology were applied to summarize the phenomenon and regularity of acupoint sensitization for MDD,and to explore the related theoretical mechanisms.[Results]A total of 29 literature related to acupoint sensitization of MDD was included.Acupoint sensitization of MDD involved in multiple forms,including heat sensitization,chemical sensitization,pain sensitization,and so on,and the testing means were diverse.The most common sensitized acupoint was Baihui(GV20).Among these acupoints,sensitization often simultaneously occurred in Baihui(GV20)and Neiguan(PC7),Baihui(GV20)and Taichong(LR3).The acupoints and sensitization could be divided into 4 effective clusters.The meridian involved with high sensitization frequency was governor vessel.Sensitization mainly occurred in the head-face-neck area.[Conclusion]The sensitization phenomenon of MDD has many types,However,there are few related studies at present.The phenomenon of acupoint sensitization involving acupoint,meridians,and location are relatively broad.There might be a close relationship between high-frequency sensitized acupoints and common acupoints for clinical treatment,which may be related to the effect of different acupoints and the etiology and pathogenesis of MDD.

Objective To evaluate the effectiveness and safety of acupuncture in patients with Major Depressive Disorders.Methods Search the database for relevant literature published before April 15,2023.Select randomized controlled trial that meeting the enrollment criteria,evaluate the quality of the literature and classify before meta-analysis systematic evaluation.Results 15 RCTs are included in this study,with a total of 1077 patients.The results showed that acupuncture treatment,compared with antidepressants alone,The score of Hamilton Depression Scale(HAMD)in patients with liver-qi depression disorder[MD=-0.73,95%CI(-1.22,-0.24),P<0.05],the score of TCM Syndrome Scale[MD=-1.89,95%CI(-2.35,-1.44),P<0.001],effective rate[RR=1.09,95%CI(1.03,1.153),P=0.001]and TESS score[MD=-2.76,95%CI(-3.68,-1.85),P<0.001]were statistically significant.Compared with fluoxetine hydrochloride,the effective rate of HAMD scale score was statistically significant[RR=1.07,95%CI(1.01,1.14),P<0.05].Conclusion Compared with antidepressants alone,acupuncture therapy has the advantages for the improvement of HAMD score in patients,the improvement of Traditional Chinese medicine symptoms,and significantly less adverse effects than those in the control group.Through this study,it is considered that acupuncture can be a safe and effective treatment modality.However,due to the quantity and quality of the included literature,the above conclusions still need to be verified by more high-quality clinical trials.
