Depression is a severe mental illness. Although existing antidepressant medications have shown efficacy in many patients, a significant proportion show poor responses to current treatments, necessitating the need for novel therapeutic approaches. Photobiomodulation (PBM), an emerging physical therapy, has recently shown promising efficacy in the treatment of depression, as indicated by two systematic reviews, and is characterized by high safety and good tolerability. However, challenges remain in areas such as light delivery techniques and optimization of treatment parameters. This review summarizes the antidepressant mechanisms of PBM, various methods of light transmission, and recent research progress on its application in the treatment of depression. It also discusses issues related to safety, tolerability, and impact of specific parameters, aiming to provide insights and recommendations for future research on PBM as a therapy for depression.

Ultrasound therapy and considerable progress in molecular imaging technologies have allowed the use of ultrasonic microbubbles not only in image enhancement but also in targeted drug or gene delivery as drug or gene carriers, respectively. Hence, ultrasound microbubbles carrying drugs or genes have become a novel type of tumor-targeting therapy technology. They do not emit radiation and are thus safe. Additionally, they are efficient and easy to reuse and facilitate drug or gene release. All these features offer attractive prospects for the treatment of liver cancer and provide novel treatment ideas for the disease. This article reviews the mechanism, applications, and existing problems of ultrasonic microbubbles in the treatment of liver cancer.

Objective:To explore the related risk factors of antepartum depression and anxiety,and to provide the theoretical support for early screening,clinical intervention and prevention of antepartum depression and anxiety.Methods:At the time of 28 weeks of prenatal examination,the Edinburgh Postnatal Depression Scale (EP-DS),Self-Rating Anxiety Scale (SAS)were used to survey 2112 pregnant women who were selected from Maternal and Child Health Hospital of Kunming City.Non conditional logistic regression analysis was used to explore the re-lated risk factors of prenatal depression and anxiety.Results:At the 28 weeks of pregnancy,the detection rate of de-pression symptoms and anxiety symptoms were 25.4% and 6.6%.Logistic regression analysis showed that the risk factors for perinatal depression symptoms were younger age (OR =0.80,95%CI:0.68 -0.94),not stick to work during pregnancy (OR =1.18,95%CI:1.02 -1.36),not satisfied with the living environment (OR =1.50,95%CI:1.23 -1.83),expectations for boys (OR =0.86,95%CI:0.77 -0.96),not only daughter (OR =1.37,95%CI:1.06 -1.76),unplanned pregnancy (OR =1.38,95%CI:1.10 -1.72).The risk factors for perinatal anxiety symp-toms were being not satisfied with the living environment (OR =1.64,95%CI:1.19 -2.26),not harmonious with her husband (OR =2.01,95%CI:1.20 -3.37),unplanned pregnancy (OR =1.50,95%CI:1.05 -2.14).Conclu-sion:It suggests that the pregnant women with younger age,less working during pregnancy,being not satisfied with the living environment,having more expectations for boys,being not only daughter,with unplanned pregnancy are more likely to suffer from antepartum depression;those being not satisfied with living environment,having harmoni-ous relation with her husband,and with unplanned pregnancy are more likely to suffer from antepartum anxiety.
