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 investigate the association between auditory processing and problem behaviors in preschool children,as well as the mediating role of executive function.Methods A total of 2 342 preschool children were selected from 7 kindergartens in Nanjing,China from June to August 2021.They were evaluated using Preschool Auditory Processing Assessment Scale,Conners Parent Symptom Questionnaire,and Behavior Rating Inventory of Executive Functioning-Preschool version.Children with different demographic features were compared in the scores and the abnormality rates of auditory processing,problem behaviors,and executive function.The influencing factors of the total scores of auditory processing,problem behaviors,and executive function were evaluated using multiple linear regression analysis.Whether executive function was a mediating factor between auditory processing and executive function was examined.Results Sex and grade were the main influencing factors for the total score of auditory processing(P<0.05),and sex,grade,parental education level,and family economic status were the main influencing factors for the total scores of problem behaviors and executive function(P<0.05).The auditory processing score(rs= 0.458,P<0.05)and problem behavior score(rs=0.185,P<0.05)were significantly positively correlated with the executive function score,and the auditory processing score was significantly positively correlated with the problem behavior score(rs=0.423,P<0.05).Executive function played a partial mediating role between auditory processing and problem behaviors,and the mediating effect accounted for 33.44% of the total effect.Conclusions Auditory processing can directly affect the problem behaviors of preschool children and indirectly affect problem behaviors through executive function.[Chinese Journal of Contemporary Pediatrics,2024,26(2):174-180]

OBJECTIVES: To investigate the characteristics of auditory processing (AP) in preschool children with attention deficit hyperactivity disorder (ADHD) using Preschool Auditory Processing Assessment Scale (hereafter referred to as "auditory processing scale"). METHODS: A total of 41 children with ADHD and 41 typically developing (TD) children were assessed using the auditory processing scale, SNAP-IV rating scale, and Conners' Kiddie Continuous Performance Test (K-CPT). The auditory processing scale score was compared between the TD and ADHD groups. The correlations of the score with SNAP-IV and K-CPT scores were assessed. RESULTS: Compared with the TD group, the ADHD group had significantly higher total score of the auditory processing scale and scores of all dimensions except visual attention (P<0.05). In the children with ADHD, the attention deficit dimension score of the SNAP-IV rating scale was positively correlated with the total score of the auditory processing scale (r_s30=0.531, P<0.05; r_s27=0.627, P<0.05) as well as the scores of its subdimensions, including auditory decoding (r_s=0.628, P<0.05), auditory attention (r_s=0.492, P<0.05), and communication (r_s=0.399, P<0.05). The hyperactivity-impulsivity dimension score of the SNAP-IV rating scale was positively correlated with the hyperactivity-impulsivity dimension score of the auditory processing scale (r_s=0.429, P<0.05). In the children with ADHD, the attention deficit dimension score of the K-CPT was positively correlated with the total score (r_s30=0.574, P<0.05; r_s27=0.485, P<0.05) and the hyperactivity-impulsivity dimension score (r_s=0.602, P<0.05) of the auditory processing scale. CONCLUSIONS Preschool children with ADHD have the risk of AP abnormalities, and the auditory processing scale should be used early for the screening and evaluation of AP abnormalities in children.

Effective drugs for chronic obstructive pulmonary disease(COPD), a complex chronic lung disease, have long been difficultly determined, while traditional Chinese medicine(TCM) has played a critical effect in the treatment of such disease. A new approach for the prediction based on data analysis by integrating TCM basic theories and modern science is urgently needed apart from clinical experiments. In this study, an efficacy evaluation system of COPD was established based on the multi-target efficacy evaluation system of Chinese medicine to analyze the medication regularity and characteristics, such as efficacies, properties, meridian tropism,and core combinations of Chinese medicines. The characteristics of classical prescriptions in the intervention of COPD were explored from modern pharmacology. The results showed that the Chinese medicines in the classical prescriptions in the treatment of COPD were dominated by heat-clearing, phlegm-resolving, dampness-dispelling, exterior-releasing, deficiency-tonifying, and interior-warming drugs. Among them, dampness-dispelling, interior-warming, and heat-clearing drugs resulted in higher perturbation efficiency in the disease network than some western medicines on the market, suggesting that these drugs possessed better efficacies in the treatment of COPD. In the classic prescriptions, warm-heat drugs were equivalent to cold-cool drugs in number, while the proportion of warm-heat drugs gradually raised with the increase in the perturbation efficiency. Additionally, core combinations in the classical prescriptions,such as heat-clearing/heat-clearing, dampness-dispelling/dampness-dispelling, and phlegm-resolving/heat-clearing, could achieve better efficacy for COPD. The present study preliminarily screened out the efficacies of Chinese medicines in the treatment of COPD based on scientific data through the multi-target efficacy evaluation system to explore the effect of Chinese medicine on COPD from modern pharmacology, explain the mechanism of TCM treatment of lung diseases, and provide references for the development of drugs targeting COPD.

Objective:To observe the clinical efficacy of modified Buyang Huanwutang combined with electroacupuncture （EA） in the treatment of traumatic spinal cord injury （TSCI） due to Qi deficiency and blood stasis. Method:Eighty-seven TSCI patients who met the inclusion requirements were randomly divided into an observation group （n=44） and a control group （n=43）. On the basis of comprehensive western medical treatments， patients in the control group were further provided with Wuwei Tongshuan oral liquid，10 mL per time，three times per day， while those in the observation group received modified Buyang Huanwutang，one bag per day，for 12 consecutive weeks. Besides， EA was performed in both groups in the same way， once per day， six times per week， for six weeks in total. The American Spinal Injury Association （ASIA） motor score， modified Barthel index （MBI），visual analog scale （VAS） pain score，Berg balance scale （BBS） score，modified Ashworth scale （MAS） score， spinal cord independence measure-Ⅲ（SCIM-Ⅲ） score， lower limb range of motion （ROM）， and Qi deficiency and blood stasis syndrome score before and after treatment were evaluated， followed by the recording of the occurrence of complications during treatment. The brain-derived nerve growth factor （BDNF）， nerve growth factor （NGF）， vascular endothelial growth factor （VEGF）， neurotrophic factor-3 （NT-3）， malondialdehyde （MDA） and superoxide dismutase （SOD） levels before and after treatment were determined. Result:The motor， light touch， needling sensation， MBI， and BBS scores of the observation group were higher than those of the control group （P<0.01）， while the AS and MAS scores were lower（P<0.01）. The angles of adductor and straight leg raising in the observation group were greater than those of the control group （P<0.01），but the Qi deficiency and blood stasis syndrome score was lower（P<0.01）. Both the scores of self-care， respiration， and sphincter management in SCIM-Ⅲ and the total score in the observation group were elevated as compared with those of the control group （P<0.01）. The cumulative incidence of complications in the observation group was 34.09%，significantly lower than 55.81% in the control group （χ²=4.149，P<0.05）. Compared with the control group， the observation group exhibited remarkably increased BDNF， NGF， VEGF， NT-3， and SOD （P<0.01） and decreased MDA （P<0.01）. Conclusion:Modified Buyang Huanwutang combined with EA is effective in alleviating spinal cord injury， promoting neural functional recovery， improving independence in activities of daily living， reducing the incidence of complications of patients with TSCI， which may be related to the amelioration of ischemia and hypoxia， inhibition of lipid peroxidation， and acceleration of nerve cell repair and regeneration.

A pair of new tirucallane triterpenoid epimers, picraquassins M and N (1> and 2), were isolated from the stems of Picrasma quassioides (D. Don) Benn. Their structures were determined based on comprehensive spectroscopic and X-ray crystallographic analyses. In addition, their AChE inhibitory activity, cytotoxicity against five human tumour cell lines (SW480, MCF-7, HepG2, Hela, and PANC-1), and antimicrobial activity against two bacteria (Staphylococcus. aureus 209P and Escherichia coli ATCC0111) and two fungi (Candida albicans FIM709 and Aspergillus niger R330) were evaluated.

Objective:To detect IL-35 in mononuclear cells of peripheral blood and lung tissue with BCG infected mouse,and to analyze its effect on the tuberculosis immune mechanism and pathology.Methods: Mycobacterium tuberculosis infecting animal model was made by BCG injection in wild type C57BL/6 mouse.Then,mice were sacrificed in different time points.The peripheral blood and lung tissue were isolated.The bacterial load and histopathological analysis in lung tissue were performed,and the expression of IL-35 subunits P35 and EBI3 in monocytes were detected by flow cytometry.Furthermore,the correlation of IL-35-expressing monocytes with the load of bacterium was analyzed.Results:The expression of P35 and EBI3 in monocytes in peripheral blood and lung tissue of BCG-infected mice was significantly higher than that of the control group,and the peripheral blood of the experimental group was significantly increased at 4 weeks after infection.The expression of EBI3 in lung tissue diaplayed significant rising trend.The correlation analysis showed that the P35 expression was positively correlated with the expression of EBI3 in monocyte,and the IL-35-ex-pressing monocyte in lung tissue was negatively correlated with the load of bacteria.The IL-35-expressing monocyte in peripheral blood and lungs increased significantly at 2-week and 4-week,while it increased in lung tissue at 8 week,significantly.Conclusion: BCG-infects mouse monocytes with high expression of IL-35,it may participate in anti-tuberculosis immune regulation.

Objectives: To analyze and understand the risk factors related to HIV new infections among men who have sex with men (MSM). Methods: A longitudinal observational study among MSM was conducted to collect information on HIV related behaviors and sero-conversion. Univariate and multivariate generalized estimating equations (GEE) were used to discuss the risk factors for HIV new infection. Results: A total number of 4 305 MSM were followed during 2013-2015. Among those self-reported MSM who are seeking partners on the Interner tended to have higher proportion on receptive anal intercourse and consistent condom use during anal intercourse than the subgroups seeking their partners in gay bars or bathrooms. HIV incidence among followed MSM during the study period appeared as 4.3/100 person years, with adjusted RR (aRR) of HIV infection for receptive anal intercourse as group 2.20 (95% CI: 1.49-3.24) times than that of insertion anal intercourse group. Those who used rush-poppers (aRR=1.55, 95% CI: 1.10-2.17), unprotected anal intercourse (aRR=2.24, 95%CI: 1.62-3.08), and those with syphilis infection (aRR=2.95, 95%CI: 2.00-4.35) were also risk factors for HIV new infections. After controlling other factors, the relationship between the ways of seeking partners and HIV new infection was not statistical significant. Conclusion: Risk factors for HIV new infection among MSM appeared complex and interactive, suggesting that further studies are needed to generate tailored strategies for the prevention of HIV epidemic among MSM population.
