Objective:To explore the clinical manifestations of IgG4-related diseases（IgG4-RD） complicated with moderately differentiated adenosquamous carcinoma of the parotid gland, the diagnostic criteria for IgG4-related diseases and parotid malignant tumors, treatment regimens, and the application of fine-needle aspiration in disease diagnosis, so as to reduce clinical misdiagnosis and missed diagnosis. Methods:A retrospective analysis was conducted on the case data of a patient with IgG4-related diseases（IgG4-RD） complicated with moderately differentiated adenosquamous carcinoma of the parotid gland admitted to our department in March 2024. The clinical characteristics, imaging findings, preoperative puncture results, and postoperative pathological features were analyzed, and relevant literatures on both diseases were reviewed and summarized. Results:The elderly male patient was admitted due to "a mass in the parotid area in front of the right ear for more than 3 months". Through clinical examination, imaging examination, laboratory examination, and preoperative needle biopsy, the diagnosis of "right parotid moderately differentiated adenosquamous carcinoma complicated with IgG4-related disease" was considered. It was also considered that IgG4-related disease did not involve other organs before surgery, so no systemic hormone therapy was given before or after surgery. After surgery combined with postoperative radiotherapy, follow-up showed that neither the parotid tumor nor IgG4-related disease recurred. Conclusion:"IgG4-related disease complicated with moderately differentiated adenosquamous carcinoma"is a rare clinical disease. Both lack typical clinical manifestations and specific imaging features, and the diagnosis is mostly unclear before surgery. Pathological examination is of great significance in the diagnosis of the disease, while fine-needle aspiration has limited value in the diagnosis, which should attract the attention of clinicians. In addition, for patients with both diseases, individualized treatment plans should be formulated.

Objective To explore the value of thyroid nodule fine needle aspiration cytology(FNAC)combined with B-Raf proto-oncogene,serine/threonine kinase(BRAF)gene detection in the differential diagnosis of benign and malignant thyroid tumors.Methods According to the results of pathological examination,198 patients with thyroid nodules were divided into the benign lesion group(n=107)and the malignant lesion group(n=91).All patients underwent ultrasound-guided FNAC,and expression of BRAF gene was detected by real-time fluorescence quantitative polymerase chain reaction.The value of FNAC,BRAF gene detection and combined detection in the differential diagnosis of benign and malignant thyroid tumors was analyzed by Kappa consistency test and receiver operating characteristic(ROC)curves.Results The nodules were mostly under envelope in the malignant lesion group,while in the benign lesion group,which were mostly located within glands(P＜0.05).FNAC results showed that 62 cases with type II Bethesda,26 cases with type III Bethesda,29 cases with type IV Bethesda,14 cases with type V Bethesda and 67 cases with type VI Bethesda.There were significant differences in diagnostic positive rates between FNAC,BRAF gene detection,combined detection and pathological examination(P＜0.05).The area under ROC curve(AUC)of FNAC combined with BRAF gene detection for differentiating benign and malignant thyroid tumors was 0.871(95%CI:0.816-0.914),sensitivity was 90.11%,specificity was 84.11%and Kappa value was 0.737.The AUC of FNAC diagnosis was 0.833(95%CI:0.774-0.882),sensitivity was 76.92%,specificity was 89.72%and Kappa value was 0.672.The AUC of BRAF gene detection was 0.829(95%CI:0.770-0.879),sensitivity was 78.02%,specificity was 87.85%and Kappa value was 0.663.Conclusion FNAC combined with BRAF gene detection can improve differential diagnosis efficiency for benign and malignant thyroid lesions,especially enhancing the diagnostic sensitivity.

Objective:To investigate the clinical features and prognostic factors of newly-treated elderly acute myeloid leukemia (AML) patients with intermediate-risk karyotype.Methods:A retrospective case series study was conducted. A total of 87 newly-treated elderly AML patients with intermediate-risk karyotype in the First Affiliated Hospital of University of Science and Technology of China (Anhui Provincial Hospital) from January 2013 to December 2023 were selected. The clinical characteristics were summarized. The Kaplan-Meier method was used for survival analysis and Cox proportional hazards model was used to make univariate and multivariate analyses of prognostic factors.Results:The median age [ M ( Q1, Q3)] of 87 patients was 69 (60, 87) years. The patients with normal karyotype and abnormal karyotype accounted for 77.1% (67/87), 22.9% (20/87), respectively. A total of 74 patients (85.1%) had 1 or more gene mutations, of which FLT3-ITD, NPM1 mutation, CEBPA mutation and WT1 high expression accounted for 29.9% (26/87), 26.4% (23/87), 19.5% (17/87), and 65.5% (57/87), respectively; additionally, 44.7% (39/87) of patients had 2 or more gene mutations. The objective response rate of patients after induction therapy was 47.7% (41/87), while the relapse rate was 73.2% (30/41). The median progression-free survival (PFS) time was 7.8 months, and the median overall survival (OS) time was 12.1 months. Univariate analysis result revealed that age, FLT3-ITD, hypomethylating agents, and minimal residual disease complete remission (MDR-CR) were factors influencing the OS of newly-treated elderly AML patients with intermediate-risk karyotype (all P < 0.05). Multivariate analysis indicated that MDR-CR was an independent risk factor for OS (yes vs. no: HR = 0.27, 95% CI: 0.14-0.51, P < 0.001). Conclusions:Newly-treated elderly AML patients with intermediate-risk karyotype have a high relapse rate and poor prognosis, and MDR-CR is identified as an independent influencing factor for the prognosis of these patients.

Objective:To document any effect of combining transcranial magnetic stimulation (rTMS) with peripheral magnetic stimulation (rPMS) to relieve shoulder pain in hemiplegic stroke survivors.Methods:Sixty hemiplegic stroke survivors with shoulder pain were randomly divided into a Central Group ( n=20), a Peripheral Group ( n=20), and a Combined Group ( n=20). In addition to routine pharmacological intervention and rehabilitation training, the Central Group received 10Hz rTMS over the M1 area of the affected hemisphere, the Peripheral Group received 20Hz rPMS at Erb′s point of the affected limb, while the Combined Group received rTMS followed by rPMS. Before as well as after 2 and 4 weeks of treatment, all were assessed using a numerical pain intensity rating scale (NRS), for passive range of motion (PROM) of the shoulder joint, and using the Fugl-Meyer upper extremity assessment (FMA). Results:Before the treatment there were no significant differences among the 3 groups. After 2 weeks there was significant improvement in the average shoulder PROM and FMA scores, and a significant decrease in the average NRS ratings. After 4 weeks there was continued significant improvement. After 2 and 4 weeks, the Combined Group gave significantly lower NRS ratings than the others and had greater average shoulder PROM improvement. The average FMA score of the Combined Group (36.10±13.32) after two weeks was significantly better than those of the Central and Peripheral groups. However, no significant differences were found between the Central and Peripheral Groups in the other measurements.Conclusions:Both rTMS and rPMS can relieve shoulder pain and promote the recovery of motor function, with superior synergistic effects observed in their combined application.

Objective: To explore the associations of family structure with adolescent mental health and health associated behaviors, to support interventions to decrease the occurrence of psychological problems and adverse health associated behaviors among adolescents in families without two parents. Methods: The multi stage stratified random cluster sampling method was used to select 18 700 adolescents of the 13 districts and cities from Jiangsu Province for a questionnaire survey on mental health and health associated behaviors, to compare differences in mental health and health associated behaviors among adolescents with different family structures. Results: Among the adolescents, 82.1% had two parent families, 8.6% had single mother families, 4.0% had single father families, and 5.3 % had families with both parents absent. After controlling for age, urban/rural areas, gender, academic period and region, Logistic multivariate regression analysis showed that compared with adolescents from two parent families, the incidence of depression, social anxiety and bullying on campus of adolescents with single mother families increased significantly( OR=1.31, 1.15, 1.36，P ＜0.05). Compared with adolescents in two parent families, adolescents in families without two parents had significantly more types of health risk behaviors, and those in single mother families had significantly less frequent intake of a healthful diet( OR =0.81), significantly more smoking( OR =1.20), drinking behaviors( OR =1.22), and significantly less moderate intensity physical activity ( OR =0.84) and shorter duration of sleep( OR =0.87)( P <0.05). Conclusion Psychological and health associated problems were significantly higher among adolescents in families without two parents than in those with two parent families. Psychological problems and adverse health associated behaviors were particularly prominent among adolescents in single mother families.
