Objective:To analyze the correlation between thymus dose-volume parameters and lymphopenia in patients with early-stage breast cancer (BC) receiving adjuvant radiotherapy (RT).Methods:Medical records of 54 patients with early-stage BC who received postoperative adjuvant RT in the Second Affiliated Hospital of Soochow University from January to December 2019 were retrospectively analyzed. Absolute lymphocyte counts (ALC) were collected at 1 month before (baseline) and weekly during RT. Lymphopenia was graded based according to the common terminology criteria for adverse events version 5.0 and nadir/baseline ALC was calculated. The thymus was delineated according to anatomical boundaries in the original RT planning system. Dosimetric parameters were obtained from the dose volume histograms. Stepwise multiple linear regression analysis was used to explore the factors associated with nadir/baseline ALC. The cutoff values of dosimetric parameters for predicting ≥grade 3 lymphopenia were obtained using the receiver operating characteristic (ROC) curve.Results:The proportion of 54 patients experiencing ≥ grade 3 lymphopenia was 38.9%. The median value of thymus volume, mean dose, V 5 Gy, V 10 Gy were 14.02 cm 3, 4.95 Gy, 36.18%, and 6.61%, respectively. Stepwise multiple linear regression analysis revealed that baseline ALC ( P=0.005), quadrant location ( P=0.005) and mean thymus dose ( P<0.001) were significantly associated with nadir/baseline ALC. ROC curve analysis indicated that the cutoff values of thymus mean dose, V 5 Gy and V 10 Gy for predicting ≥ grade 3 lymphopenia were 6.12 Gy, 35.2%, and 7.4%, respectively. Conclusions:Lymphopenia in early-stage BC patients is significantly correlated with high dosimetric parameters of the thymus during postoperative adjuvant RT. Thymus may be considered as an organ at risk during RT.

Objective:To evaluate the efficacy of role-playing games with parental involvement and immediate therapist feedback for children with autism spectrum disorder(ASD)and to explore their impact on parental compe-tence,thereby providing new insights for ASD rehabilitation.Method:Seventy children with ASD were randomly assigned to either a control or an intervention group.The control group received traditional one-on-one role-playing therapy with parents as observers.In addition to this therapy,the intervention group participated in a 60-minute parent-inclusive role-playing session with real-time therapist feedback.Assessments of children's social perspective-taking abilities and parental competence were conducted at pre-and post-intervention and at follow-up.Children's developmental outcomes were further evalu-ated using the Griffiths Scales at the same timepoints.Result:Sixty-four participants provided valid data.The intervention group showed significant improvements in social perspective-taking post-intervention and at follow-up compared to baseline(P<0.05).At follow-up,chil-dren in the intervention group also scored higher on personal and social,hearing,and language development domains of the Griffiths Scale than the control group(P<0.05).Parental competence in the intervention group significantly increased(P<0.05).Conclusion:The integrated intervention of role-playing games with immediate feedback effectively enhances so-cial perspective-taking in children with ASD,promotes developmental levels,and strengthens parental competence.

Objective:To investigate the role of adenosine triphosphatase phospholipid transporter 10a(ATP10a)methylation assay in the triage of atypical squamous cell of undetermined significance(ASC-US)and low-grade squamous intraepithelial lesions(LSIL)in cervical cytology.Methods:188 patients with cervical exfolia-ted cells of ASC-US and LSIL were selected,and High-risk human papilloma virus(HR-HPV)typing and cervical biopsy results of the patients were collected at the same time.The cervical biopsy pathology results were used as the gold standard,and they were divided into inflammation,LSIL,high grade squamous intraepithelial lesions(HSIL)and cervical squamous cell carcinoma(SCC).Classify inflammation and LSIL as LSIL-group,HSIL and SCC as HSIL+group to compare the efficacy of ATP10a methylation and HR-HPV testing for diagnosis of HSIL+in this population(including HSIL and SCC).Results:The methylation detection value of ATP10a in the inflam-mation,LSIL,HSIL,and SCC patients were 19.035(16.478,20.823),13.446(5.890,20.674),10.336(4.733,17.336),4.223(1.713,7.754),respectively.The methylation detection value of ATP10a in the LSIL-group was 17.812(10.787,20.686),while that in the HSIL+group was 7.251(3.170,14.194).There was a statistically sig-nificant difference between the groups(Z=-5.824,P＜0.001).The proportion of HR-HPV positivity in the LSIL-group was 70.9％,which was lower than that of the HSIL+group(88.2％),and the difference was statistically significant(Z=-2.887,P=0.004).The specificity,negative predictive value(NPV),and area under the receiver operating characteristic(ROC)curve(AUC)of ATP10A methylation diagnosis of HSIL+(66.0％,79.1％,and 0.747)were higher than those of HR-HPV detection(29.1％,50.7％,0.587).Sensitivity and positive predictive value(PPV)(78.8％and 65.7％)were lower than those of HR-HPV testing(88.2％and 75.0％).when using ATP10a methylation instead of HR-HPV detection for triage of cytological abnormalities(ASC-US,LSIL),the col-poscopy referral rate could be reduced to 54.3％.In the ASC-US population,the AUC(0.683)for the diagnosis of HSIL+by ATP10a methylation test was higher than that of HR-HPV test(0.599),and the difference was statisti-cally significant(P=0.028).In the LSIL population,the AUC(0.828)for the diagnosis of HSIL+by ATP10a methylation test was still higher than that of HR-HPV test(0.563),and the difference was statistically significant(P=0.005).Conclusions:ATP10a methylation levels increased with the severity of cervical lesions,and the di-agnostic efficacy of ATP10a methylation detection for the severity of cervical lesions may not be lower than HR-HPV typing.
