Parental burnout is a set of negative symptoms resulting from parenting roles and chronic paren-ting stress,such as feelings of depletion associated with the parenting role and maintaining emotional distance from children.This paper analyzes a representative body of literature on parental burnout published through 2023 and pro-vides an overview of the literature around parental burnout definition and measurement,antecedent variables,and consequential variables.The results indicate that demographic variables,individual and family factors can influence parental burnout,and that the consequences of parental burnout are primarily reflected in the parents themselves and their children.The prevalence of parental burnout is influenced by sociocultural factors,but the mechanism of action is unclear and there is less research on interventions for parental burnout.Future research should pay full attention to the role and place of sociocultural factors in the study of parental burnout and actively pursue intervention research on parental burnout.

Objective:To revise the Effort-Reward Imbalance in Household and Family Work(ERI-HF)in a sample of middle school parents,and examine its adaptation.Methods:The Parenting Behavior Effort-Reward Im-balance Scale(ERI-PB)was formed by translating and linguistically adjusting ERI-HF,combining with expert eval-uation results.Parents of 1 062 seventh-grade students in a middle school were selected and surveyed twice with an interval of one and a half months on a family basis.The Perceived Partner Responsiveness Scale(PPRS),Parenting Anxiety Questionnaire(PAQ),and Satisfaction with Marital Scale(SMS)were used to test the criterion-related va-lidity.Results:There were 22 items in ERI-PB,which contained 3 factors of effort,reward,and over-commitment,the factor load of each factor was 0.39-0.84,and the cumulative variance explanation rate was 47.27％.The ab-solute values of correlations between the scores of effort,reward,over-commitment and PPRS,PAQ,SMS were 0.14-0.53(Ps＜0.01).The Cronbach α coefficients of the three factors were 0.76-0.91,the McDonaldωcoef-ficients were 0.76-0.91,and the retest reliabilities(ICC)were 0.50-0.70.Conclusion:The ERI-PB shows good validity and reliability in a group of parents of middle school students.

Objective To investigate the effect of artesunate(ART)on neuroinflammation in depressed mice by regulating the cyclic guanosine monophosphate-adenosine monophosphate synthase(cGAS)-stimulator of interferon gene(STING)pathway.Methods Mice were divided into model group,control group,low-dose ART group,high-dose ART group,fluoxetine group,and high-dose ART+RocA(cGAS-STING pathway activator)group.Sugar solution consumption experiment and forced swimming experiment were applied to evaluate the depressive behavior of mice;HE staining microscopy was applied to detect pathological changes in hippocampal tissue;ELISA method was applied to detect the level of interleukin-6(IL-6),tumor necrosis factor-α(TNF-α),serotonin(5-HT)and dopa-mine(DA);TUNEL staining microscopy was applied to detect neuronal apoptosis;Western blot was applied to detect Bcl-2 associated X protein(Bax),p53,cGAS,and STING proteins.Results Compared to the control group,the mice in the model group exhibited neuronal pustule degeneration,the sugar water consumption rate,level of 5-HT and DA decreased,the rest time of forced swimming increased.The level of IL-6 and TNF-α,neuronal apoptosis rate,expression of Bax,p53,cGAS,and STING proteins all elevated(P＜0.05);Compared with model group,the damage to hippocampus neurons in the ART low-dose group,ART high-dose group and fluoxetine group neuronal pus-tular degeneration was alleviated,while sugar water consumption rate,5-HT,and DA levels increased,the rest time of forced swimming reduced,the level of IL-6 and TNF-α,neuronal apoptosis rate and the expression of Bax,p53,cGAS,and STING proteins reduced(P＜0.05);RocA reversed the improvement effect of high-dose ART on depression in mice.Conclusions ART inhibits neuroinflammation and neuronal apoptosis in depressed mice,and up-regulates amine neurotransmitters expression.The mechanism is potentially related to the blocking of cGAS-STING pathway.

Objective To develop a deep learning network based on attention mechanism to identify the number of the vertical man-dibular third molar(MTM)roots(single or double)on panoramic radiographs in an automatic way.Methods The sample consisted of 1 045 patients with 1 642 MTMs on paired panoramic radiographs and Cone-beam computed tomography(CBCT)and were randomly grouped into the training(80%),the validation(10%),and the test(10%).The evaluation of CBCT was defined as the ground truth.A deep learning network based on attention mechanism,which was named as RN-MTMnet,was trained to judge if the MTM on pano-ramic radiographs had one or two roots.Diagnostic performance was evaluated by accuracy,sensitivity,specificity,and positive predict value(PPV),and the receiver operating characteristic(ROC)curve with the area under the ROC curve(AUC).Its diagnostic perform-ance was compared with dentists'diagnosis,Faster-RCNN,CenterNet,and SSD using evaluation metrics.Results On CBCT images,single-rooted MTM was observed on 336(20.46%)sides,while two-rooted MTM was 1 306(79.54%).The RN-MTMnet achieved an accuracy of 0.888,a sensitivity of 0.885,a specificity of 0.903,a PPV of 0.976,and the AUC value of 0.90.Conclusion RN-MTM-net is developed as a novel,robust and accurate method for detecting the numberof MTM roots on panoramic radiographs.

Objective:To compare and explore the diagnostic performance of adding value of transabdominal and transvaginal contrast-enhanced ultrasound (CEUS) to Ovarian-Adnexal Reporting and Data System (O-RADS US) risk stratification and management system in differential diagnosis of adnexal masses.Methods:A total of 180 adnexal masses with solid components in 175 women were enrolled retrospectively between September 2021 and November 2022. All patients underwent routine Doppler ultrasound examinations and CEUS examinations. Among these masses, 107 masses underwent with transabdominal CEUS, 58 masses underwent with transvaginal CEUS, and 15 masses underwent both transvaginal and transabdominal CEUS. All patients were scheduled for surgery and pathological results served as the reference standard. Routine Doppler ultrasound and CEUS images and video were reviewed by a subspecialty radiologist using Vuebox software. The O-RADS US was downgraded or upgraded according to the CEUS characteristics of the masses. The diagnostic accuracy was assessed using ROC curve analysis. The area under the ROC curve (AUC) was calculated to compare the diagnostic performance of adding value of transabdominal and transvaginal CEUS to O-RADS US.Results:The diagnostic performance of adding transabdominal and transvaginal CEUS to O-RADS US were both significantly higher than of O-RADS US alone (transabdominal CEUS: AUC 0.83 vs 0.76, P=0.018; transvaginal CEUS: AUC 0.92 vs 0.81, P=0.013). Combination of transvaginal CEUS and O-RADS US was superior to that of combination of transabdominal and O-RADS US in the differential diagnosis of adnexal masses ( P=0.047). When the maximal diameter of adnexal masses ≤40 mm, transabdominal combined with O-RADS US presented the lowest diagnostic performance, with an AUC of 0.73. Conclusions:Combination of transvaginal CEUS and O-RADS US was superior to that of combination of transabdominal and O-RADS US in assessing adnexal masses with solid components. When the maximal diameter of adnexal masses ≤40 mm, transvaginal CEUS examination was recommended.

AIM: Previous studies have suggested that big stick design (BSD) method can only be used in clinical trials of two treatments with equal proportion, which has good statistical performance and has become the recommended choice of randomized methods. This study expands BSD method, so that it can be applied to three groups, and provides more randomized methods for clinical trials. METHODS: On the basis of BSD method used in two treatments with equal proportion, the derivation conditional allocation probability of BSD method used in three treatments with equal proportion was carried out. BSD method was compared with simple randomization (SR) method, permuted block design (PBD) method and block urn design (BUD) method by Monte-Carlo simulation in balance and randomness. RESULTS: In terms of balance, PBD method was the best, followed by BUD method, BSD method, and SR method was the worst. In terms of randomness, SR method was the best, followed by BSD method, BUD method and PBD method. The comprehensive performance showed that BSD method was better than BUD method, PBD method and SR method. CONCLUSION: The expanded BSD method used in three treatments with equal proportion has good comprehensive performance, and it can be the recommended randomization method for clinical trials of three treatments with equal proportion.

Objective:To investigate the intra- and inter-observer agreements of different experiencers using the Ovaria-adnexal Reporting and Data System (O-RADS) in the evaluation of adnexal masses.Methods:Totally 48 patients with adnexal masses (48 masses, mean size 9.5±4.7 cm, range 2.3-18.6 cm) found by ultrasound examination in the Third Affiliated Hospital of Sun Yat-sen University, from May 2019 to March 2020 were retrospectively analyzed. All the masses were confirmed by pathology or surgery. Four observers were divided into 2 senior doctors (Doctor 1 and Doctor 2) and 2 junior doctors (Doctor 3 and Doctor 4). Each observer independently evaluated adnexal masses twice using ultrasound O-RADS before and after systematic training, with an interval of 60 days. The intra-observer and inter-observer agreements were analyzed before and after training.Results:The inter-observer agreement between senior doctors were both excellent before and after systematic training (weight Kappa: 0.833 vs 0.802, percentage of agreement: 83.3% vs 81.3%). Whereas there was difference in the inter-observer agreement between non-experienced observers before and after training (weight Kappa: 0.399 vs 0.824, percentage of agreement: 50.0% vs 77.1%). After training, inter-observer agreement between junior doctors was significantly improved and comparable to senior (weight Kappa: 0.824 vs 0.802, percentage of agreement: 77.1% vs 81.3%). Before and after systematic training, the intra-observer agreements of the same doctor, the senior physicians were better than the junior (weight Kappa: 0.882 and 0.843 vs 0.440 and 0.605; percentage of agreement: 87.5% and 83.3% vs 58.3% and 54.2%).Conclusions:O-RADS risk classification system is a highly reproducible method in the subjective assessment of an adnexal mass among observers with varying levels of expertise. However, systematic training before clinical application is necessary and effective for non-experienced observers.

Objective:To investigate the value of translabial ultrasound (TLUS) in female periurethral benign solid lesions (PBSL).Methods:Twenty-one female patients (21 lesions) with PBSL identified pathologically within the process of cystoscope or surgery from June 2017 to December 2020 were enrolled. All of them underwent urethral examination (UE) and TLUS. The detection rates of the lesions of UE and TLUS were compared, and the ultrasonic diagnostic accuracy and ultrasonic manifestations were analyzed.Results:Sixteen of the 21 patients showed lower urinary tract symptoms (76.19%). Among the 21 lesions, the detection rates of UE and TLUS were 52.38% (11/21) and 85.71% (18/21), respectively, the difference was statistically significant ( P=0.019). The length of 18 lesions detected by TLUS was (1.79±1.04)cm, and 13 lesions (72.22%) were shorter than 3 cm. Among 18 cases, urethral caruncle (13 cases) was the most common benign periurethral mass, the main ultrasonic manifestations of urethral caruncle showed hyperecho lesions in the middle and distal urethra, and the blood flow was mostly in a branch-like distribution. At the same time, there were 5 cases of urethral myoma and other solid lesions, the main ultrasonic manifestations of urethral myoma showed clear boundary, low echo and peripheral short strip blood flow. Using pathological results as the gold standard, the accuracy of ultrasonic diagnosis was 88.89% (16/18). Conclusions:TLUS is able to improve the detection rate of periurethral benign solid lesions, and the diagnostic concordant rate is acceptable.TLUS can provide more diagnostic and therapeutic information.
