Objective: To understand the correlation between autistic traits in children with autism spectrum disorder(ASD) and their parental behaviors, so as to provide evidence for improving social behavior in children with ASD. Methods: A total of 62 children aged 4-7 years diagnosed with ASD at Guangdong Provincial Work Injury Rehabilitation Hospital and Guangzhou Yuexiu District Children s Hospital from October 2021 to May 2025 were selected as the ASD group. A random number table method was used to select 62 healthy children of the same age from 3 ordinary kindergartens in Guangzhou as the control (typically developing,TD) group. The Parental Behavior Inventory and Social Responsiveness Scale were used to evaluate parental behaviors and autistic traits in both groups. The t-test and multiple linear regression were used to analyze the relationship between autistic traits in children with ASD and parental behaviors. Results: Compared with the TD group, the ASD group had significantly higher scores in social awareness, social cognition, social communication, social motivation, autistic behavior patterns, and the total score of social responsiveness, with statistically significant differences ( t =35.83, 46.17, 64.36, 41.45, 49.46,101.15, all P <0.01). The score of parental support/participation in the ASD group (24.61±4.30) was lower than that in the TD group (31.27±4.58), while the score of parental hostility/coercion in the ASD group (25.51±2.72) was higher than that in the TD group (12.75±2.72), with statistically significant differences ( t = -8.34, 26.14, both P <0.01). The total score of the Social Responsiveness Scale was negatively correlated with the dimension score of parental support/participation behaviors, and positively correlated with the dimension score of parental hostility/coercion behaviors ( r =-0.60, 0.91,both P <0.05). After adjusting for covariates such as children s age, gender, and primary caregiver, ASD children with exclusive breastfeeding ( β =-8.79) and parental support/participation behaviors ( β = -0.79 ) had a lower risk of autistic traits, while children with parental hostility/coercion behaviors ( β =4.62) had a higher risk of autistic traits (all P <0.05). Conclusion Autistic traits in children with ASD may be related to their parental behaviors and early feeding mode.

OBJECTIVE: To assess the value of combined detection strategies using multiple technologies for the genetic testing and prenatal diagnosis for pedigrees affected with Duchenne muscular dystrophy (DMD) for optimizing genetic counseling and reproductive guidance. METHODS: This study has involved 142 subjects from 65 suspected DMD families who had visited the First Affiliated Hospital of Chongqing Medical University from January 2018 to December 2023. A combination of multiple ligation-dependent probe amplification (MLPA), quantitative fluorescence PCR, and next-generation sequencing (NGS) was used. After confirming the genetic diagnosis of the probands, prenatal diagnosis was provided for carrier mothers. This study was approved by the Medical Ethics Committee of the hospital (Ethics No.: 2021-264). RESULTS: Among the 142 subjects tested, 73 cases of large deletions/duplications and 15 cases of small variants of the DMD gene were detected. The hotspot regions for the variants were exons 45 to 55. A total of 41 variant types were identified, of which 3 were previously unreported. In 19 families with suspected patients, 7 exonic deletions, 2 exonic duplications, and 3 small variants were identified. Prenatal diagnosis was performed on 48 fetuses from 46 families, revealing 16 affected male fetuses (including 12 with deletion variants, 2 with duplication variants, and 2 with small variants). Seven carrier females were identified among the 16 female fetuses (including 6 with deletions and 1 with duplication). Among the couples with an affected fetus, 16 had opted to terminate the pregnancy, while the parents of 32 fetuses had chosen to continue with the pregnancy. In families undergoing prenatal diagnosis, 53 (79.1%) pregnant women and their family members were found to carry mutations of the DMD gene. CONCLUSION The combined detection strategy of MLPA, qPCR, and NGS can encompass large deletions/duplications and small variants of the DMD gene, providing timely and accurate prenatal diagnosis for families affected by DMD. In conjunction with genetic counseling, this can effectively reduce the risk of producing affected offspring, which is crucial for the prevention and control of this disease.

Objective:To compare the efficacy of anrikefon and tegileridine for analgesia in patients with moderate-to-severe pain after abdominal surgery with general anesthesia.Methods:In this multicenter, randomized, double-blind, active-controlled clinical trial, 101 patients with moderate to severe pain (numeric pain rating scale [NRS] score ≥4 within 4 h after operation) after abdominal surgery with general anesthesia between February 24 and April 1, 2025, aged 18-70 yr, with a body mass index of 18-40 kg/m 2, were assigned to anrikefon group ( n=50) and tegileridine group ( n=51) in a 1∶1 ratio using stratified blocked randomization. Double-dummy design was employed to maintain blinding. Each group received an initial intravenous injection of anrikefon 1 μg/kg or tegileridine 1 mg, followed by connection to a patient-controlled intravenous analgesia (PCIA) pump (the PCIA solution contained normal saline in anrikefon group; the PCIA solution contained tegileridine 5 mg in tegileridine pump) within 10 min. If the patient′s NRS score ≥4 at 8 and 16 h after the initial injection, anrikefon 1 μg/kg was intravenously injected in anrikefon group, and tegileridine group received the equal volume of normal saline. The primary efficacy endpoint was the sum of pain intensity difference (SPID) over the first 24 h after the initial dose (SPID 0-24h). The secondary efficacy endpoints included the incidence and severity of vomiting and nausea, incidence of postoperative nausea and vomiting(PONV), the proportion of patients who received antiemetic treatment, and total consumption of antiemetics within 0-24 h after the initial dose, NRS score at rest ≤ 1 at 24 h after the initial dose, and NRS score at rest ≤ 3 over the first 24 h after the initial dose. Safety indicators included adverse events, vital signs, physical examination findings, 12-lead ECG and laboratory test indicators, and adverse events of special interest. Results:Compared with tegileridine group, no significant change was found in the SPID 0-24h ( P>0.05), and the incidence of vomiting, PONV, proportion of patients requiring antiemetic medication, and total consumption of antiemetics were significantly decreased within the first 24 h after the initial dose in tegileridine group ( P<0.05). One treatment-emergent adverse event of Common Terminology Criteria for Adverse Events grade 3 or higher occurred in tegileridine group, while no treatment-emergent adverse events of Common Terminology Criteria for Adverse Events grade 3 or higher were found in anrikefon group. Among the adverse events of special interest, one case of respiratory depression and one case of cough occurred in tegileridine group, while one case of cough occurred in anrikefon group, with no respiratory depression. Conclusions:Anrikefon and tegileridine provide comparable analgesic efficacy for moderate-to-severe pain after abdominal surgery with general anesthesia. However, anrikefon exhibits an advantage in reducing the risk of PONV, with a superior safety profile.

Objective To analyze the clinical features and surgical treatment strategies of T4a thyroid cancer.Methods We retrospectively analyzed patients with thyroid cancer treated in the Department of Head and Neck Surgery of Sichuan Cancer Hospital from January 2004 to May 2021.A total of 303 cases were included and statistically analyzed for pathological type,invaded organs,surgical approach,survival time,and overall survival rate.The postoperative survival curves of the patients were analyzed using the Kaplan Meier method.Results Of the 303 patients enrolled,53 patients were lost to follow-up,and the 1-year,3-year and 5-year overall survival rates were 98.4％(246/250),97.0％(224/231)and 90.2％(92/102),respectively.Of the 94 patients with recurrent laryngeal nerve invasion only,13 were lost to follow-up,and the 1-year,3-year and 5-year overall survival rates were 100％(81/81),98.7％(77/78)and 97.4％(38/39),respectively.There were 151 patients with invasion of recurrent laryngeal nerve and tracheal/laryngeal/esophageal nerve,31 of them were lost to follow-up,and the 1-year,3-year and 5-year overall survival rates were 96.7％(116/120),95.3％(101/106)and 82.2％(37/45),respectively.According to the survival curve analysis,the group with recurrent laryngeal nerve invasion only had an advantage in overall survival time over the group with recurrent laryngeal nerve and tracheal/laryngeal/esophageal invasion.Conclusion Surgical resection is supposed to be preferred for T4a thyroid cancer if there is a chance of surgery.A reasonable surgical strategy,radical surgery while preserving the vital tissues and organs,and one-stage repair and reconstruction can bring patients a better quality of life and prognosis.

Objectives:To investigate the prognostic value of soluble growth stimulation expressed gene 2 protein(sST2)combined with N-terminal pro-brain natriuretic peptide(NT-proBNP)in patients with ST-segment elevation myocardial infarction(STEMI)undergoing primary percutaneous coronary intervention(PCI). Methods:A total of 206 patients who were diagnosed with STEMI for the first time and underwent emergency PCI from August 2020 to February 2021 in the People's Hospital of Liaoning Province were enrolled.Patients were followed up for 3 years and divided into major adverse cardiac event(MACE,a composite endpoint event including cardiac death,stroke,heart failure,and ischemia-driven revascularization)group and MACE-free group.Multivariate cox analysis was performed to determine the independent risk factors for the prognosis of primary PCI in STEMI patients;the predictive value of sST2 and NT-proBNP for the occurrence of MACE in STEMI patients undergoing primary PCI was assessed by ROC analysis and the prediction of MACE by each factor by itself and the combined variables was analyzed with the Delong test. Results:There were 62 cases of MACE during the 3-year follow-up.Compared with the MACE-free group,patients in the MACE group had higher levels of sST2 and NT-proBNP,higher proportion of patients with left anterior descending branch lesions,anterior wall myocardial infarction,lower LVEF,and higher proportion of coronary artery slow flow(all P<0.05).Multivariate Cox analysis showed that sST2(HR=1.018,95%CI:1.012-1.024,P<0.001)and NT-proBNP(HR=1.001,95%CI:1.000-1.010,P<0.001)were independent predictors of MACE.According to the statistical analysis of ROC and Delong test,the AUC of combined sST2 and NT-proBNP in predicting MACE was 0.854,the sensitivity was 64.5%,the specificity was 93.1%,and the combined prediction of prognosis was better than that of individual prediction,with statistically significant difference(Z=2.119,P=0.034;Z=2.178,P=0.029). Conclusions:Serum sST2 and NT-proBNP are valuable predictors of MACE after emergency PCI in patients with STEMI,and the predictive efficacy increases with combined assessment of both sST2 and NT-proBNP.

Objective:To investigate the clinical characteristics of patients complicated with Hashimoto’s thyroiditis (HT) and papillary thyroid micro-carcinoma (PTMC) and risk factors for central lymph node metastasis (CLNM) by analyzing the clinical data.Methods:Clinical data of 770 patients with PTMC admitted to Head and Neck Surgery Center of Sichuan Cancer Hospital from May. 2015 to Nov. 2017 were retrospectively analyzed, including 250 HT-PTMC patients (observation group) and 520 non-HT-PTMC patients (control group) . There were 197 males and 573 females, with a male to female ratio of 1.00:2.91. Into observation indexes included patient’s age, gender, serum thyroid stimulating hormone (TSH) , thyroglobulin antibody (TG-Ab) , thyroid peroxidase antibody (TPO-Ab) , number of foci, diameter of foci, calcification of foci, location of foci (with or without extra-glandular invasion) , number of nodules (no matter benign or malignant) , and lymph node metastasis in central and lateral cervical regions. SPSS 22.0 software was used for statistical analysis. Normally distributed data were expressed ± s. The difference between observation group and control group was compared by chi-square test of single factor analysis. The risk factors of CLNM of the observation group were analyzed with multivariate Logistic regression, the difference was statistically significant if P<0.05. Results:There were statistically significant differences between the observation group and the control group in age ( P=0.006) , gender ( P<0.001) , TSH ( P<0.001) , TG-Ab ( P<0.001) , TPO-Ab ( P<0.001) , number of nodules ( P=0.016) , and central lymph node ( P<0.001) . Compared with non-HT-PTMC group, HT-PTMC group had a higher proportion of women under 55 years old, and both TG-Ab and TPO-Ab had higher positive rates. Patients with HT-PTMC were more likely to show polynodule changes, but their central lymph node metastasis rate was lower than that of the non-HT-PTMC group. Single-factor analysis showed that the number of cancer foci, calcification of cancer foci, and location of cancer foci were significantly correlated with the CLNM of HT-PTMC patients (all P<0.001) . Multivariate Logistic regression analysis showed that multiple cancer foci ( P<0.001) , invasion and capsule ( P<0.001) , and cancer foci with calcification ( P=0.005) were independent risk factors for CLNM. Conclusions:HT-PTMC is more common in women under 55 years of age, and most of them show multiple nodules in bilateral glandular lobes, often accompanied by elevated serum TSH, TG-Ab and TPO-Ab levels. Meanwhile, the lymph node metastasis rate of HT-PTMC is relatively low, and the prognosis may be relatively good. In HT-PTMC, the risk of multiple carcinoma foci, cancer foci with calcification, cancer foci invasion and the occurrence of CLNM is higher. Preventive central lymph node dissection helps to reduce the occurrence of postoperative cervical lymph node recurrence.

Objective: To analyze the risk factors of lymph node metastasis in central region of patients with papillary thyroid microcarcinoma (PTMC). To evaluate the reliability of different risk factors on the prognosis of cervical lymph node metastasis in PTMC patients, and to provide the clinical support for PTMC in the central area. Methods: The clinical data of 700 patients with PTMC treated with surgery from January 2015 to July 2017 were analyzed retrospectively. Risk factors for lymph node metastasis in central region were analyzed by single factor analysis, multivariate Logistic regression analysis and receiver operating characteristic curve (ROC) curve. Results: Central lymph node metastasis (CLNM) rate was 48.29% (338/700). Multifactor analysis indicated that age≤45 years old, male, multifocality, capsule invasion, the tumor calcification and tumor diameter ≥5 mm were independent risk factors for CLNM in patients with PTMC. In the risk prediction of CLNM, the optimal critical value of diameter prediction was 7 mm and the area under the curve (AUC) of ROC=0.647. The optimal threshold for age prediction was 41 years old and AUC=0.597. Single factor analysis for ROC curve showed that gender factor AUC=0.588, tumor number factor AUC=0.627, tumor location factor AUC=0.613. and calcification factor AUC=0.603. The ROC curve of multiple risk factors was analyzed according to age, gender, diameter, location, number of cancer foci and calcification, and AUC=0.768. Conclusions Age less than 45 years old, male, multiple cancer foci, focal invasion and capsule invasion, calcification, and tumor diameter ≥5 mm are independent risk factors for CLNM of PTMC. With an accumulation of multiple risk factors, CLNM risk increases, and central lymph node dissection should be recommend.

Objective To explore the clinical effect of new type rectal cancer radiotherapy individualized fixation device in the radiotherapy of rectal cancer. Methods From June 2015 to December 2016,60 patients with rectal cancer who accepted the external irradiation in Zhejiang Tumor Hospital were divided into two groups by random number table method. A group(31 cases) received new type rectal cancer radiotherapy position fixation devices with thermoplastic film. B group(29 cases) received simple foam pad with thermoplastic film. Before each treatment,Cone beam CT(CBCT) scan was conducted. The applied CBCT image and the planned reconstruction image were compared in the direction of X(left and right),Y(upper and lower)and Z(front and rear) axis. The setup error was recorded, and the correlation between the two groups was analyzed. Results The average setup error of patients in A group in X (left and right),Y(upper and lower),Z(front and rear) axis were (1. 61 ± 0. 18)mm,(1. 82 ± 0. 13)mm,(1. 91 ± 0. 11)mm,respectively. The average setup error of patients in B group in X(left and right),Y(upper and lower),Z (front and rear) axis were (2. 22 ± 0. 13)mm,(2. 43 ± 0. 14)mm,(2. 36 ± 0. 13)mm,respectively. There were statistically significant differences between the two groups(t=14. 958,17. 501,11. 283,all P＜0. 001). Conclusion The new type of rectal cancer radiotherapy position fixing device is more comfortable than the simple foam pad,and the setting error is smaller than the simple foam pad.

Objective: To explore the advantages and clinical efficacy of free chimeric perforator flap based on the descending branch of circumflex femoral artery applied to tongue reconstruction after advanced tongue cancer resection. Methods: From October 2013 to December 2018, 57 cases received tongue and oral base reconstruction surgeries using the descending branch of circumflex femoral artery chimeric perforator flap, including 39 males and 18 females, ranged from 20 to 76 years old. And all cases were with stage T3 and T4 tongue cancers, including 35 cases of squamous cell carcinoma, 7 cases of low differentiation cancer, 5 cases of oncosarcoma, and 10 cases of adenoid cystic carcinoma. The tongue was reconstructed by using perforator flap and muscle flap to fill the dead space at the oral floor. The artery anastomoses with the superior thyroid artery or facial artery in the receiving area, and the vein anastomoses with the internal jugular vein in the receiving area. The shape, function and local complications of the reconstructed tongue were observed after operation. Results: Of 57 cases, only one case had partial necrosis of flap, while other 56 cases with chimeric perforator flap survived. Postoperative gastric tube and tracheal cannula were removed in all patients, no cases with oral fistula. All donor sites were sutured in one stage. Postoperative radiotherapy was performed in 41 of the patients. All patients were followed up for 3 to 60 months (average of 20.7 months), with satisfactory esthetic and functional results in reconstructed tongues. Only linear scars were left in the donor areas of the legs, and no lower limb dysfunction was observed. Conclusions The descending branch of circumflex femoral artery chimeric perforator flap can used for repairing simultaneously the defects of both tongue and oral base. It is helpful to avoid the occurrence of oral fistula and to provide the reconstructed tongue with a good function. It is a good choice to use the descending branch of circumflex femoral artery chimeric perforator flap for tongue reconstruction after resection of advanced tongue cancer resection.
