Objective:To assess the use of R-R interval (RRI) sequence data collected via wearable devices to evaluate emotional dynamic factors in adolescents with depressive disorders, and to analyze their impact on diagnosis and severity assessment.Methods:Clinical data were prospectively collected from 154 adolescent inpatients with depressive disorders (132 females, 22 males; age 12-18, mean: 13.5±1.6 years) treated at the Child Psychiatry Ward of Beijing Anding Hospital, Capital Medical University between January 2023 and January 2024.A control group of 152 healthy adolescents (62 females, 90 males; age 12-18, mean 14.5±1.3 years) was recruited during the same period. RRI data were obtained using the built-in photoplethysmography (PPG) sensor in the HUAWEI Band 7 wearable device. The device′s integrated emotion evaluation system extracted arousal and emotional valence (as indicators of emotional dynamics) from the collected RRIs. A Long Short-Term Memory (LSTM) network was employed to develop a model for depression diagnosis and severity prediction, while a random forest model was applied to generate receiver operating characteristic (ROC) curves to evaluate model performance. Binary Logistic regression was conducted to investigate the influence of arousal and emotional valence on depression diagnosis and severity.Results:A total of 429 records were collected and analyzed from 306 participants. The LSTM-based diagnosis and severity assessment models achieved area under the curve (AUC) of 0.896 9 and 0.715 3, respectively, indicating good model performance. Binary Logistic regression analysis showed that arousal and emotional valence had significant effects on diagnosis and severity. Specially, lower arousal in both the first 4 hours ( β=-8.906, 95%CI:-17.497 to -0.315) and second 4 hours ( β=-3.033, 95%CI:-5.109 to -0.957) significantly predicted positive depression diagnosis ( β=-1.219, 95%CI:-2.205 to -0.233), while emotional valence in the second 4 hours showed a trend toward a positive association ( β=0.675, 95%CI:-0.107-1.457). First 4-hour emotional valence: significantly positive association with severity ( β=0.322, 95%CI: 0.067-0.577), second 4-hour arousal level: negative association with severity ( β=-0.258, 95%CI:-0.527 to 0.011), whereas arousal in the second 4 hours had a marginal negative effect (β=-0.258, 95% CI:-0.527 to 0.011). Conclusion:RRI may serve as a useful auxiliary measure in diagnosing depressive disorders and predicting severity among adolescents. Wearable smart devices offer promising potential for screening emotional dynamic factors related to adolescent depression.

Objective To discuss the curative effect of double targets percutaneous radiotfrequency thermocoagulation (PRT) on primary trigeminal neuralgia (PTN) and its safety.Methods Sixty patients with PTN were randomly divided into single target treatment group and double targets treatment group.CT guided stereotactic location was used to navigate PRT;patients in the single target treatment group only accepted one target damage and those in the double targets treatment group accepted target damage with 3 mm of deep and shallow interval.The curative effects and complications were compared one week,3 months,one and 2 years after the surgery.Results The percentage of patients with good curative effect in double targets treatment group was significantly higher than that in single target treatment group one and 2 years after surgery,with statistically significant difference (86.7％ vs.60％,70％ vs.45％,P＜0.05).Recurrence rates of double targets treatment group 3 months,one and 2 years after surgery were 0％,3.3％ and 6.7％,which were lower than those in single target treatment group (3.3％,10％ and 16.7％),without significant difference (P＞0.05).Ipsilateralfacial hypaesthesia of different degrees appeared in both groups,but complications as keratohelcosis,diplopia,chewing weakness or difficulty in opening mouth did not appear.And the degree of facial numbness in double targets treatment group was a little higher than that in single target treatment group without statistical significance (P＞0.05).Conclusion Double targets PRT used in PTN treatment can obviously improve the postoperative pain relief and do not apparently increase the degree of postoperative facial numbness as compared with single target PRT.
