ObjectiveAutism spectrum disorder (ASD) is a neurodevelopmental condition characterized by difficulties with communication and social interaction, restricted and repetitive behaviors. Previous studies have indicated that individuals with ASD exhibit early and lifelong attention deficits, which are closely related to the core symptoms of ASD. Basic visual attention processes may provide a critical foundation for their social communication and interaction abilities. Therefore, this study explores the behavior of children with ASD in capturing attention to changes in topological properties. MethodsOur study recruited twenty-seven ASD children diagnosed by professional clinicians according to DSM-5 and twenty-eight typically developing (TD) age-matched controls. In an attention capture task, we recorded the saccadic behaviors of children with ASD and TD in response to topological change (TC) and non-topological change (nTC) stimuli. Saccadic reaction time (SRT), visual search time (VS), and first fixation dwell time (FFDT) were used as indicators of attentional bias. Pearson correlation tests between the clinical assessment scales and attentional bias were conducted. ResultsThis study found that TD children had significantly faster SRT (P<0.05) and VS (P<0.05) for the TC stimuli compared to the nTC stimuli, while the children with ASD did not exhibit significant differences in either measure (P>0.05). Additionally, ASD children demonstrated significantly less attention towards the TC targets (measured by FFDT), in comparison to TD children (P<0.05). Furthermore, ASD children exhibited a significant negative linear correlation between their attentional bias (measured by VS) and their scores on the compulsive subscale (P<0.05). ConclusionThe results suggest that children with ASD have difficulty shifting their attention to objects with topological changes during change detection. This atypical attention may affect the child’s cognitive and behavioral development, thereby impacting their social communication and interaction. In sum, our findings indicate that difficulties in attentional capture by TC may be a key feature of ASD.

Objective To establish an individualized nomogram model and evaluate its efficacy to provide a possible evaluation basis for the prognosis of lower third and abdominal part of oesophageal adenocarcinoma (EAC). Methods Lower third and abdominal part of EAC patients from 2010 to 2015 were chosen from the SEER Research Plus Database (17 Regs, 2022nov sub). The patients were randomly allocated to the training cohort and the internal validation cohort with a ratio of 7∶3 using bootstrap resampling. The Cox proportional hazards regression analysis was used to determine significant contributors to overall survival (OS) in EAC patients, which would be elected to construct the nomogram prediction model. C-index, calibration curve and receiver operating characteristic (ROC) curve were performed to evaluate its efficacy. Finally, the efficacy to evaluate the OS of EAC patients was compared between the nomogram prediction model and TNM staging system. Results In total, 3945 patients with lower third and abdominal part of EAC were enrolled, including 3475 males and 470 females with a median age of 65 (57-72) years. The 2761 patients were allocated to the training cohort and the remaining 1184 patients to the internal validation cohort. In the training and the internal validation cohorts, the C-index of the nomogram model was 0.705 and 0.713, respectively. Meanwhile, the calibration curve also suggested that the nomogram model had a strong capability of predicting 1-, 3-, and 5-year OS rates of EAC patients. The nomogram also had a higher efficacy than the TNM staging system in predicting 1-, 3-, and 5-year OS rates of EAC patients. Conclusion This nomogram prediction model has a high efficiency for predicting OS in the patients with lower third and abdominal part of EAC, which is higher than that of the current TNM staging system.

Objective To evaluate the value of postoperative radiotherapy (PORT) in patients with stage ⅢA-N2 non-small cell lung cancer who received complete resection and chemotherapy. Methods Patients with stage ⅢA-N2 non-small cell lung cancer who received complete resection and chemotherapy were chosen from the SEER Research Plus Database [17 Registries, November 2012 Submission (2000-2019)]. The patients were divided into a PORT group and a non-PORT group according to whether the PORT was used. To balance baseline characteristics between non-PORT and PORT groups, R software was used to conduct a propensity score matching (PSM) with a ratio of 1 : 1 and a matching tolerance of 0.01. Both the Cox regression analysis and Kaplan-Meier survival analysis were conducted to evaluate the value of PORT in terms of overall survival (OS) and disease-specific survival (DSS). Results In total, 2468 patients with stage ⅢA-N2 non-small cell lung cancer were enrolled, including 1078 males and 1390 females with a median age of 65 (58-71) years. There were 1336 patients in the PORT group, and 1132 patients in the non-PORT group. Cox regression analysis showed that PORT was not significantly associated with OS (multivariate analysis: HR=1.051, 95%CI 0.949-1.164, P=0.338) and DSS (multivariate analysis: HR=1.094, 95%CI 0.976-1.225, P=0.123). No statistical difference was found in the OS or DSS between non-PORT group and PORT group after PSM analysis (P＞0.05). Conclusion PORT does not have a survival benefit for patients with stage ⅢA-N2 non-small cell lung cancer who received complete resection and chemotherapy.

Objective To investigate the human papillomavirus(HPV)infection and genotype distribution characteristics among male reproductive health outpatients,and to compare the differences among different age groups of outpatients.Methods A total of 1 658 males,visited in the Affiliated Hospital of Shanghai Institute of Planned Parenthood Research from 2018 to 2022,were selected and 23 HPV genotypes were detected by PCR-reverse dot hybridization.Results Among the 1 658 subjects,the overall HPV infection rate was 22.50%.Single infection accounted for 66.76%,which was the main infection type.HPV infection among different age groups were statistically significant(P<0.001),with HPV infection of 16.83%,22.87%,34.63%,and 29.35%for 18-30,31-40,41-50,and≥51 years,respectively.The top 5 high risk HPV genotypes were HPV52(3.56%),HPV16(3.26%),HPV39(2.41%),HPV51(2.17%),HPV58(2.17%),and the top 1 low risk HPV genotype was HPV81(2.90%).The proportions of infected individuals in this study that could be completely covered by bivalent,quadrivalent,and nine-valent HPV vaccines were 7.77%,12.33%,and 26.27%,respectively.Conclusion The predominant infection type among male reproductive health outpatients was single infection type.HPV 52,16,39,51 and 58 were the most common high risk genotypes,while HPV 81 was the most common low risk genotype.Individuals aged 41-50 years had the highest HPV infection rate.

The contents recorded in the rotation registration manual is not only the quantitative indicators for evaluating the quality of residency training, but also the important basis for training assessment and issuance of training certificates. In order to solve the problems of data authenticity, information delay, and repeated entry in the rotation registration manual for residency training, Shanghai East Hospital, Tongji University, launched a project to dock the electronic rotation registration manual with the hospital information system.

Objectives:To investigate clinical characteristics, outcomes and antimicrobial resistance of community-acquired Pseudomonas aeruginosa (CAPA) infections in Chinese pediatric patients. Methods:This retrospective study was conducted at 6 tertiary hospitals in China during January 2016 to December 2018. The clinical and microbiological data of CAPA infected hospitalized children in Hainan and in other regions were collected and compared, and the antimicrobial resistance patterns, clinical characteristics and antibiotic therapy were analyzed. Between different groups were compared using the Chi-square test and Mann-Whitney U test. Results:Among 91 patients, 63 cases were males, 28 cases were females, and 74 cases were from Hainan province, 17 cases were from other regians. The age of consultation was 22.5 (5.4, 44.0) months. Twenty-four cases (26%) had underlying diseases. Fever (79 cases (87%)) and cough (64 cases (70%)) were common initial symptoms. Other concomitant symptoms included wheezing 8 cases (9%), diarrhea 3 cases (3%) and vomiting 4 cases (4%). Twenty-eight cases (31%) had organ infections, including pneumonia 22 cases (24%), skin infection 5 cases (5%), meningitis, intra-abdominal infection and upper urinary tract infection each 1 case (1%). The resistance rate of CAPA isolates to cefepime (4% (4/90)), amikacin (1% (1/90)), ciprofloxacin (2% (2/90)) and levofloxacin (1% (1/89)) was low, and to ceftazidime, piperacillin, piperacillin-azobactam, carbapenem was 12% (11/90), 3/16, 18% (10/56) and 6% (5/90), respectively. Antimicrobial combination therapy accounted for 52% (47/91) of empirical therapy and 59% (52/88) of definite therapy. Two cases (2%) were hopeless discharged, and 3 cases (3%) died during hospitalization. The worse prognosis of CAPA infection is significantly different among children in other regions and in Hainan (4/17 vs. 1% (1/74), χ2=9.74, P<0.05). Conclusions:The invasive CAPA-infection has regional difference in incidence and prognosis in China. Clinical symptoms and signs are non-specific. CAPA strains isolated from pediatric patients display low level of resistance to most of the common antipseudomonal antibiotics. The proportion of poor prognostic outcome is lower in Hainan than in other regions.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To evaluate the effectiveness of oral-nasal oxygen supply mouth guard in painless gastroscopy for snoring patients.Methods:The snoring patients who underwent painless gastroscopy at two Endoscopy Centers of Shanghai East Hospital, Tongji University in July 2022 were randomly divided into the observation group (using oral-nasal oxygen supply mouth guard) and the control group (using ordinary nasal oxygen tube and mouth guard). Parameters such as the wearing time and the removal time of the mouth guard, lowest pulse oxygen saturation (SpO 2), incidence of hypoxemia, and the satisfaction of medical staff were compared between the two groups. Results:The wearing time of mouth guard was 11.63±0.84 seconds and the removal time was 5.33±0.76 seconds in the observation group ( n=40), which were lower than those in the control group ( n=47) (14.91±1.21 seconds, t=-14.463, P<0.001; 10.38±0.80 seconds, t=-30.095, P<0.001). The wearing satisfaction score was 9.80±0.61, the lowest SpO 2 was (96.70±3.42)%, the removal satisfaction score was 9.75±0.67, and the anesthesiologists' satisfaction score was 9.20±1.42 in the observation group, which were higher than those in the control group [7.70±0.93, t=12.209, P<0.001; (94.06±3.72)%, t=3.417, P=0.001; 7.96±0.98, t=9.803, P<0.001; 8.13±1.35, t=3.615, P=0.001] with significant difference. There was no significant difference in the incidence of hypoxemia [10.00% (4/40) VS 14.89% (7/47), χ2=0.130, P=0.718] and endoscopic physician satisfaction score (9.30±0.97 VS 9.02±1.31, t=1.112, P=0.269) between the two groups. Conclusion:The oral-nasal oxygen supply mouth guard is easy to wear and remove, effectively reducing SpO 2 fluctuations during painless gastroscopy for snoring patients. It can enhance medical staff satisfaction with high clinical value.

The global COVID-19 coronavirus pandemic has infected over 109 million people, leading to over 2 million deaths up to date and still lacking of effective drugs for patient treatment. Here, we screened about 1.8 million small molecules against the main protease (M^pro) and papain like protease (PL^pro), two major proteases in severe acute respiratory syndrome-coronavirus 2 genome, and identified 1851M^pro inhibitors and 205 PL^pro inhibitors with low nmol/l activity of the best hits. Among these inhibitors, eight small molecules showed dual inhibition effects on both M^pro and PL^pro, exhibiting potential as better candidates for COVID-19 treatment. The best inhibitors of each protease were tested in antiviral assay, with over 40% of M^pro inhibitors and over 20% of PL^pro inhibitors showing high potency in viral inhibition with low cytotoxicity. The X-ray crystal structure of SARS-CoV-2 M^pro in complex with its potent inhibitor 4a was determined at 1.8 Å resolution. Together with docking assays, our results provide a comprehensive resource for future research on anti-SARS-CoV-2 drug development.
