Cardiovascular disease caused by radiotherapy(RT)is the most common cause of non-neoplastic death in cancer patients.Having advantages of dynamic observation and no radiation,echocardiography has been widely used in evaluating heart structure and function of patients after RT,which has become the preferred imaging method for screening,diagnosing and monitoring radiation-induced heart disease(RIHD).The research progresses of echocardiography in evaluating RIHD were reviewed in this article.

Objective To evaluate the clinical efficacy of stellate ganglion block(SGB)combined with intranasal dexmedetomidine for the treatment of insomnia.Methods A total of 64 patients aged 18 to 75 with insom-nia were randomly assigned to either the experimental group(DS group)or the control group(S group).The S group received SGB treatment for 14 consecutive days,whereas the DS group received an additional intranasal dexmedeto-midine spray at a dose of 100 μg,administered 30 minutes before bedtime on days 1 through 6,in conjunction with SGB.We measured and recorded the Pittsburgh Sleep Quality Index(PSQI),Self-Rating Depression Scale(SDS),Self-Rating Anxiety Scale(SAS)scores,and Psychomotor Vigilance Test(PVT)results for both groups at three time points:baseline(T1),the day after treatment(T2),and one month after treatment(T3).Results Intra-group Com-parison:In both the DS and S groups,PSQI scores and dimensionspecific scores at T2 and T3 were significantly lower compared to T1(P<0.05).SAS and SDS scores in both groups showed a significant reduction at T3 compared to T1 and T2(P<0.05),while PVT results exhibited no significant changes(P>0.05).Inter-group Comparison:The PSQI scores and dimensionspecific scores in the DS group at T2(8.44±2.99)and T3(8.22±2.60)were significantly lower than those in the S group at T2(10.88±2.56)and T3(10.88±2.84)(P<0.05).However,no significant differences were observed in SDS and SAS scores between the DS and S groups at T2 and T3(P>0.05).Conclusion Compared to standalone SGB,the combination of SGB with intranasal dexmedetomidine significantly enhances sleep quality in patients with insomnia,while not impacting their levels of anxiety,depression,or alertness.
