Autism Spectrum Disorder （ASD） is a neurodevelopmental disorder with rapidly increasing global prevalence， characterized by core symptoms of social communication deficits and stereotyped repetitive behaviors. Although genetic predisposition， abnormal epigenetic regulation， perinatal environmental exposure， and nutritional-metabolic imbalances are recognized as major risk factors， the precise etiological mechanisms remain incompletely understood. Current clinical management primarily relies on behavioral interventions， with limited pharmacological options accompanied by adverse effects. Recent studies have demonstrated the unique therapeutic value of active components from Chinese herbal medicine in ASD intervention. This article reviews the mechanisms underlying various Chinese herbal active components in ASD treatment， including improvements in synaptic dysfunction， blood-brain barrier impairment， neurotransmitter regulation， cerebellar dysfunction， immune dysregulation and neuroinflammation， oxidative stress， programmed neuronal cell death， and lipid metabolism. These bioactive components exhibit multi-target and multi-pathway regulatory effects， providing novel therapeutic strategies and directions for ASD.

Objective:To investigate the correlation between the hemodynamic pattern of non-culprit vessel stenosis and long-term vessel-oriented composite outcome(VOCO) in patients with acute ST-segment elevation myocardial infarction (STEMI).Methods:From January 2019 to December 2021, 233 consecutive patients with STEMI and non-culprit vessel stenosis were prospectively enrolled at Shanghai East Hospital. The median follow-up duration was 3.9 years. The 367 non-culprit vessels of the 233 patients were divided into the VOCO group (33 vessels, 9.0%) and the non-VOCO group (334 vessels, 91.0%). Parameters pertaining to the hemodynamic pattern of non-culprit vessel stenosis between the two groups were compared. Receiver operating characteristic (ROC) curves were used to assess the correlation between hemodynamic pattern and VOCO, and Cox multivariate regression and logistic multivariate regression analyses were applied to identify independent predictors of VOCO.Results:The 233 enrolled patients were aged (62.5±12.9) years, with 193 males (82.8%). In the VOCO group, the maximum quantitative flow ratio (QFR) decreased within 20 mm of the QFR-assessed segment, the difference in QFR across the entire vessel, the length of functionally significant vessel, and the maximum gradient of QFR decrease (dQFR/dsmax) were significantly greater than those in the non-VOCO group. ROC curve analysis showed that the optimal threshold for predicting VOCO using dQFR/dsmax was 0.009 6 (area under the curve: 0.691, 95% CI: 0.606-0.775, P<0.001). Multivariable Cox regression analysis revealed that dQFR/dsmax was an independent predictor of VOCO ( HR=1.199, 95% CI: 1.070-1.343, P=0.002). When anatomical and functional stenosis severities were included in the model, a high pullback pressure gradient (PPG) index ( HR=1.572, 95% CI: 1.052-2.351, P=0.027) emerged as an independent predictor of VOCO. Multivariable logistic regression analysis revealed that a low PPG index( OR=2.851, 95% CI: 1.945-4.178, P<0.001) was an independent predictor of QFR≤0.80 without long-term VOCO. Conclusion:In patients with STEMI, localized hemodynamic patterns of coronary artery stenosis, characterized by high dQFR/dsmax and high PPG index, are associated with long-term VOCO.

Objective To explore the effectiveness of da Vinci Robot Xi system-assisted single-incision laparoscopic surgery for treating benign ovarian lesions in children and adolescents.Methods From June 2020 to March 2023,13 cases of benign ovarian lesions were operated by using a specially designed 4-channel single-incision laparoscopic device assisted by the da Vinci Robot Xi system.The docking between the da Vinci Robot and the patient was completed,and the affected ovaries were cut open with a non-powered scissors to expose the tumor tissue.The tumor tissue was removed as completely as possible along the edge of the tumor,and an absorbable suture was used to seal the wound followed by restoring the umbilical structure.Results All the 13 cases underwent ovarian benign lesion resection through a single incision in the umbilical region,without conversion to open surgery.The surgical time was 81-246 min,with an average of 161.4 min.The intraoperative bleeding volume was 5-50 ml,with an average of 21.2 ml.During the operation,2 cases of ovarian torsion and 3 cases of ovarian benign lesion rupture(with postoperative drainage tube placement)were found.Postoperative pathological findings showed 9 cases of mature teratoma,2 cases of serous cystadenoma,and 2 cases of simple cyst.The postoperative hospitalization time was 2-7 d,with an average of 4.2 d.There was 1 case of postoperative incision infection who was cured after antibiotic treatment.The follow-up period was 6-36 months,with an average of 21.1 months.No tumor recurrence or complications occurred,and all the patients had hidden scars on the umbilical incision.The patients and their families were satisfied with the postoperative appearance.Conclusion The application of da Vinci Robot Xi system-assisted single-incision laparoscopic surgery in the treatment of benign ovarian lesions in children and adolescents is safe and feasible,which can be considered as an option for treating such conditions.

Objective To investigate the clinicopathological characteristics and the factors affecting the prognosis of patients with resectable sarcomatoid carcinoma of the bladder(SCB).Methods A retrospective analysis was conducted with the clinical data of patients with resectable SCB treated at the Second Hospital of Tianjin Medical University between September 2008 and December 2023.The patients were divided into two groups,a bladder-preserving surgery(BPS)group and a radical cystectomy(RC)group,according to the specific surgical approach used for each patient.Kaplan-Meier survival curves were used to evaluate overall survival(OS)in both groups,and Cox regression models were employed to identify risk factors affecting survival.Results A total of 77 patients with resectable SCB were included.Among them,35 patients(45.5％)underwent BPS,while 42 patients(54.5％)underwent RC.Ki-67 expression≥30％was observed in 91.7％of the patients.A total of 92.2％of the patients was tested positive for cytokeratin(CK)and 98.1％for vimentin.In addition,62.5％and 37.5％of patients had the human epidermal growth factor receptor 2(Her-2)scores of 0 and 1+,respectively.The median follow-up time was 23.2 months(ranging from 0.4 to 164.7 months).The 1-year,3-year,and 5-year survival rates for the BPS group and the RC group were as follows,76.2％vs.84.9％,46.7％vs.61.1％,and 35.6％vs.43.2％,respectively.Multivariate Cox regression analysis revealed that in the RC group,age ≥ 75 years old(hazard ratio[HR]=3.836,95％confidence interval[CI]:1.168-12.595,P=0.027),tumor multiplicity(HR=3.439,95％CI:1.235-9.574,P=0.018),and lack of adjuvant therapy(HR=3.164,95％CI:1.015-9.862,P=0.047)were independent risk factors affecting survival.In the BPS group,female sex was identified as an independent risk factor for survival(HR=3.601,95％CI:1.200-10.804,P=0.022).Conclusion Ki-67,CK,and vimentin are significantly overexpressed in SCB patients,while Her-2 is either unexpressed or expressed at low levels.In the RC group,tumor multiplicity,age ≥75 years,and lack of postoperative adjuvant therapy are independent risk factors for overall survival.Female sex is an independent risk factor affecting prognosis in the BPS group.

Dendritic cell-based cancer vaccines (DC vaccines) have been proved efficient and safe in immunotherapy of various cancers, including melanoma, ovarian and prostate cancer. However, the clinical responses were not always satisfied. Here we proposed a novel strategy to prepare DC vaccines. In the present study, a fusion protein SNU containing a secretin-penetratin (SecPen) peptide, NY-ESO-1 and ubiquitin was designed and expressed. To establish the DC vaccine (DC-SNU), the mouse bone marrow-derived DCs (BMDCs) were isolated, pulsed with SNU and maturated with cytokine cocktail. Then peripheral blood mononuclear cells (PBMCs) from C57BL/6 mice inoculated intraperitoneally with DC-SNU were separated and cocultured with MC38/MC38

Objective: To investigate the etiologic and epidemiologic features of an infectious diarrhea outbreak in a boarding school in Fuyang city, Anhui province. Methods: Traceability hypothesis of this study was tested according to the epidemiological characteristics of the cases. Feces, anal swabs, water samples and food residues related to the patients and chefs were collected for pathogen isolation and detection. Biochemical identification, virulence gene detection, drug susceptibility test, PFGE and multilocus sequence typing were performed. Results: The incidence rate (3.41%) of different dormitory buildings within the water supply area by shallow wells was higher than that (0.98%) of the deep wells, with statistical significance (χ²=17.215, P<0.001). Sixteen strains belonged to the Shigella Sonneri family were isolated from the patient’s samples, and all carrying the ipaH gene. Seven strains belonged to sen and ial genes. Set1 gene that did not appear in all the 16 strains were highly resistant to ampicillin, tetracycline, compound xinnomine, cefazoline, cefotaxime, gentamicin, naphthidinic acid and streptomycin, including 9 strains to doxycycline. The pulse field pattern of the 16 strains of Shigella sonneri appeared the same, with the ST type as ST152. Conclusion When combined data from the etiological and epidemiological investigation, it was confirmed that Shigella sonneri was the pathogen of this outbreak, and water from the shallow wells might be responsible for the source of infection.

Objective To know the anxiety status of preschool children in rural areas and to explore its influential factors. Methods Subjects of 1363 rural preschool children aged 3-6 years were selected from Anhui Province( Changfeng and Feixi county of Hefei city; Qianshan county of Anqing city; Funan county of Fuyang city) . The primary caregivers of preschool children were investigated by Chinese version of Spence Preschool Anxiety Scale (SPAS),Devereux Early Childhood Assessment for Preschoolers (DECA-P2) ,Neglect Norms for Children Aged 3 to 6 Years in Rural Areas of China,Adaptation Partnership Growth Affection Resolve (APGAR),Self-rating anxiety scale (SAS) and Self-rating depression (SDS). Result-s Among the 1363 preschool children,the positive rate of anxiety was 14. 7％. Physical injury fears score was highest (1. 24±0. 84),followed by social phobia anxiety (0. 86±0. 75) and separation anxiety (0. 85± 0. 74) . Except for obsessive compulsive disorder,the other four types of anxiety and total anxiety scores were negatively correlated with the total protective factors of mental resilience (r=-0. 054- -0. 070,P<0. 05). Besides,all anxiety scores were positively correlated with behavioral problems(r=0. 121-0. 237,P<0. 05)and neglect degree (r=0. 157-0. 269,P<0. 05). The results of multiple linear regression analysis of different anxiety types showed that gender,family type,family income status,parental rearing pattern was consistent or inconsistent,children' s neglect degree,behavior problem and anxiety/depression status of primary caregivers were the main factors affecting the anxiety level of preschool children in rural areas. Conclusions In order to reduce or avoid anxiety of preschool children,it is necessary to establish a good family environment,im-prove parents' upbringing level,and take effective education intervention.

Objective To prepare an influenza A(H1N1) split-virus vaccine and observe its safe-ty and effectiveness. Methods According to the process for preparing seasonal flu split-virus vaccine two batches of vaccine were prepared with the flu A (H1N1) vaccine virus strain recommended by WHO. The pilot products were tested against the requirements of flu split-virus vaccine. Results The quality of the pi-lot vaccine has been tested by National Control Laboratory and conformed to the requirements. Nine hundred and sixty volunteers received one dose of vaccine containing either 15 μg or 30 μg of hemagglutinin. The re-suits indicated the both seroconversion rate and protection rate were higher the 70%. The GMT of HIAb of the volunteers who received 1 dose of 15 μg increased significantly by 15, 39, 37 and 25 times compared to those before vaccination in the age groups of 3-11, 12-17, 18-59 and ≥60, respectively. And 26, 72, 68 and 36 times rise were found in the postvaccinated volunteers of 30 μg group. The total adverse reaction rates of 15 μg and 30 μg dose group were 29.38% and 43.75%, respectively. The grade 2 adverse reaction rates of 15 μg and 30 μg dose group were 6.25% and 15.42%, and the grade 3 adverse reaction rates of 15 μg and 30 μg dose group were 0.83% and 1.46%, respectively. No serious adverse reactions were found. Conclusion The influenza A (H1N1) split-virus vaccine prepared according to the requirements of season-al flu vaccine is safe and effective.

OBJECTIVE: To investigate the expressions of LL-37 and IL-8 in chronic sinusitis with nasal polyps. METHOD: Semi-quantitative reverse transcription polymerase chain reaction (RT-PCR) and immunohistochemical staining were used to detect the expressions of LL-37 and IL-8 in nasal polyp tissues of 31 patients with chronic sinusitis and inferior turbinate tissues of 11 patients with chronic rhinitis. RESULT: LL-37 and IL-8 mRNA were all positively expressed in all nasal polyps and inferior turbinate tissues. There were significant increases of LL-37 and IL-8 mRNA expressions in nasal polyps compared with the inferior turbinate tissues (P < 0.01). There were also significant increases of positive expression rates of LL-37 and IL-8 protein in nasal polyps, compared with the inferior turbinate tissues (P < 0.01). There was a positive relationship between the mRNA and protein expressions of LL37 and IL-8 (P < 0.01). CONCLUSION The expressions of LL-37 and IL-8 in nasal polyps suggest that they may play a role in the pathogenesis of chronic sinusitis. Besides its innate immune, LL-37 could enhance human body's anti-infected function by increasing acquired immune.
