Objective To discuss the application of partial antiplatelet drug genotype detection and thromboelastography-platelet mapping(TEG-PM)in guiding the selection of antiplatelet regimens in patients with intracranial aneurysms(IAs)after receiving stenting.Methods A total of 106 patients with IAs in the First Affiliated Hospital of Kunming Medical University,who underwent implantation of stent and received the testings of platelet-endothelial aggregation receptor 1(PEAR 1)and clopidogrel-related gene-cytochrome P450 enzyme 2C19(CYP2C19),and some of whom received TEG-PM testing from January 2019 to August 2022,were collected for this study.The patients were divided into group A(gene detection group,according to the drug-related gene detection results to adjust the medication)and group B(combination group,according to the two testing results to guide the medication).The patient's gender,age,testing data were collected,and the occlusion of IAs,stent intimal hyperplasia,drug-related hemorrhagic and ischemic complications during follow-up period were recorded.Results A total of 123 IAs lesions in 106 patients were treated.The patient's mean age was(53.67±6.66)years,67 patients were female.Group A had 41 patients and group B had 65 patients.No statistically significant differences in the baseline data,IAs features,stent types used,and medication regimen existed between the two groups(all P＞0.05).In Group A,the ischemic complications and hemorrhagic complications occurred in two patients each.In Group B,no ischemic complications occurred and 4 patients developed hemorrhagic complications.The difference in the incidence of related complications between the two groups was not statistically significant(P=0.287 and P=0.782 respectively).There were no statistically significant differences in the postoperative one-month and 3-month intimal hyperplasia grade and the aneurysm occlusion rate between the two groups(all P＞0.05).The postoperative 6-month overall intimal hyperplasia grade in Group A was slightly higher than that in Group B,and the difference was statistically significant(P=0.034).Conclusion In order to improve the precision and individualized treatment of antiplatelet therapy,it is suggested that clinicians should adopt TEG-PM-guided conventional double-antibody therapy first when making selection of testing items.For patients with insufficient inhibition rate indicated by TEG-PM,testing of the genes associated with antiplatelet drugs should be used.Based on the genetic test results it is necessary to determine the reasons for the insufficient inhibition rate as well as to adjust the medication promptly according to the specific situation of the patient,so as to ensure the effectiveness of antiplatelet therapy and achieve the purpose of individualized precision therapy.

Objective To compare the differences in efficacy and safety between transarterial chemoembolization(TACE)com-bined with lenvatinib and camrelizumab(triple therapy)and TACE combined with lenvatinib(double therapy)in intermediate or advanced stage hepatocellular carcinoma(HCC).Methods The clinical data of 145 patients who were diagnosed with HCC and received triple therapy or double therapy were retrospectively collected.The differences of objective response rate(ORR),disease control rate(DCR),median progression-free survival(mPFS),median overall survival(mOS),and adverse events were compared between the two groups.Results The ORR and DCR in 1,3 and 6 months of the triple therapy group were higher than those of the double therapy group,and the differences were statistically significant in 3 and 6 months.The mPFS and mOS of the triple therapy group were higher than those of the double therapy group,and the differences were statistically significant.The Cox proportional hazards model results showed that the therapy methods,maximum tumor diameter and alpha-fetoprotein(AFP)were independent risk factors of progres-sion-free survival(PFS)and overall survival(OS).Besides,Barcelona Clinic Liver Cancer(BCLC)staging was independent risk fac-tor of OS.In terms of adverse events,the incidence of reactive cutaneous capillary endothelial proliferation(RCCEP)and hypothy-roidism in the triple therapy group were higher than those in the double therapy group,and the differences were statistically signifi-cant.Conclusion Compared with double therapy,triple therapy can significantly improve the efficacy of intermediate or advanced stage HCC,prolong patients'PFS and OS,and its safety can be well controlled.
