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 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 observe the protective effect of modified Baishile Decoction on hippocampal neuronal cells cultured in vitro;To explore its mechanism of treating post-stroke depression.Methods Hippocampal neuronal cells from mammary rats were isolated and cultured in vitro,cell injury was induced by oxygen glucose deprivation combined with lipopolysaccharide.The cells were divided into normal group,model group,blank serum group(10%)and modified Baishile Decoction containing serum group(10%).Invertedmicroscope was used to observe cell morphological changes,CCK-8 method was used to detect cell survival rate,Hoechst33342 staining was used to observe apoptosis,ELISA was used to detect Glu,5-HT,TNF-α,IL-1β,and IL-6 contents in cell supernatant,the expressions of purinergic P2X7 receptor(P2X7R)and NOD-like receptor protein 3(NLRP3)were detected by immunofluorescence staining.Results Compared with the normal group,the hippocampal neurons in the model group showed significant changes in cell morphology,the cell survival rate significantly decreased(P<0.01),the cell apoptosis increased(P<0.01);Glu,TNF-α,IL-1β,IL-6 contents in cell supernatant significantly increased(P<0.05,P<0.01),5-HT content significantly decreased(P<0.01),P2X7R and NLRP3 expressions in hippocampal neuronal cells significantly increased(P<0.01).Compared with the model group,the morphology of hippocampal neurons in modified Baishile Decoction containing serum group was significantly improved,the cell survival rate significantly increased(P<0.01),the cell apoptosis reduced(P<0.01);Glu,TNF-α and IL-1β content in cell supernatant significantly reduced(P<0.05,P<0.01),5-HT content significantly increased(P<0.01),and P2X7R and NLRP3 expressions in hippocampal neuronal cells significantly decreased(P<0.01).Conclusion Modified Baishile Decoction may exert a protective effect on oxidative glucose deprivation combined with lipopolysaccharide induced hippocampal neuronal inflammation damage by inhibiting the P2X7R/NLRP3 signaling pathway,regulating neurotransmitter secretion,and inhibiting inflammatory factor release,thus treating post-stroke depression.

OBJECTIVE To investigate the in vitro anti-inflammatory effects and mechanisms of oblongifolins A （OA） extracted from Garcinia oblongifolia. METHODS RAW264.7 cells were used as the research subject and divided into control group （0.5% DMSO）， lipopolysaccharide （LPS） group （1 μg/mL）， DEX group （10 µmol/L DEX+1 μg/mL LPS）， and low-， medium-， and high-concentration groups of OA （7.5， 15， 30 µmol/L OA+1 μg/mL LPS）. Except for the control group， the remaining groups were first stimulated with LPS for 1 hour and then mixed with drugs for 24 hours. The morphological changes of cells were observed in each group. The contents of nitric oxide （NO）， reactive oxygen species （ROS）， tumor necrosis factor-α （TNF-α）， interleukin-6 （IL-6）， IL-1β， IL-4 and IL-10 were detected in cells of each group； mRNA expression levels of TNF-α， IL-6 and IL-1β were measured. The expression of key proteins in the nuclear factor κB （NF-κB） and nuclear factor-erythroid 2-related factor 2 （Nrf2） signaling pathways in each group， as well as the nuclear translocation of NF-κB p65 and Nrf2 proteins in control group， LPS group and OA high-concentration group， were detected. RESULTS Compared to the LPS group， the number of spindle-shaped and irregular cells gradually decreased in OA groups， the contents of NO， ROS （except for OA low-concentration group）， TNF-α， IL-6 and IL-1β， the mRNA expressions of TNF-α， IL-6 （except for OA low-concentration group） and IL-1β as well as the protein expressions of phosphorylated NF-κB p65 （p-NF-κB p65）， p-IκBα， and Kelch-like ECH-associated protein 1 （Keap1） were decreased significantly （P＜0.05）. The contents of IL-4 and IL-10， protein expressions of IκBα， Nrf2 （except for OA low- and medium-concentration groups）， HO-1 （except for OA low-concentration group） and NQO1 were all increased significantly （P＜0.05）. OA of high concentration could inhibit NF-κB p65 protein nuclear translocation and promote Nrf2 protein nuclear translocation. CONCLUSIONS OA can suppress LPS-induced inflammation in RAW264.7 macrophages. The underlying molecular mechanism likely entails the inhibition of the NF-κB signaling pathway， the activation of the Nrf2 signaling pathway and the reduction of ROS and inflammatory factor release.

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.

OBJECTIVE: To screen for small molecular compounds with selective inhibitory activity against cutaneous melanoma cells with BAP1 deletion. METHODS: Cutaneous melanoma cells expressing wild-type BAP1 were selected to construct a BAP1 knockout cell model using CRISPR-Cas9 system, and small molecules with selective inhibitory activity against BAP1 knockout cells were screened from a compound library using MTT assay. Rescue experiment was carried out to determine whether the sensitivity of BAP1 knockout cells to the candidate compounds was directly related to BAP1 deletion. The effects of the candidate compounds on cell cycle and apoptosis were detected with flow cytometry, and the protein expressions in the cells were analyzed with Western blotting. RESULTS: The p53 activator RITA from the compound library was shown to selectively inhibit the viability of BAP1 knockout cells. Overexpression of wild-type BAP1 reversed the sensitivity of BAP1 knockout cells to RITA, while overexpression of the mutant BAP1 (C91S) with inactivated ubiquitinase did not produce any rescue effect. Compared with the control cells expressing wild-type BAP1, BAP1 knockout cells were more sensitive to RITA-induced cell cycle arrest and apoptosis (P < 0.0001) and showed an increased expression of p53 protein, which was further increased by RITA treatment (P < 0.0001). CONCLUSION Loss of BAP1 results in the sensitivity of cutaneous melanoma cells to p53 activator RITA. In melanoma cells, the activity of ubiquitinase in BAP1 is directly related to their sensitivity to RITA. An increased expression of p53 protein induced by BAP1 knockout is probably a key reason for RITA sensitivity of melanoma cells, suggesting the potential of RITA as a targeted therapeutic agent for cutaneous melanoma carrying BAP1-inactivating mutations.

Objective:To investigate the expression of cancer-associated fibroblasts(CAFs) marker proteins in papillary thyroid carcinoma(PTC) using immunohistochemistry and explore their correlation with clinicopathological characteristics.Methods:The clinicopathological data of 90 PTC patients at Tianjin Medical University General Hospital from December 2019 to January 2021 were retrospectively analyzed. Surgical pathological cancer tissue samples were selected for immunohistochemical staining, and control group tissues were obtained from normal thyroid tissue adjacent to the tumor lesion. Four CAFs marker proteins, including fibroblast-activated protein(FAP), α-smooth muscle actin(α-SMA), Vimentin, and platelet-derived growth factor receptor-α(PDGFR-α), were stained and scored, followed by statistical analysis.Results:The immunoreactivity score of the CAFs marker proteins were correlated with extrathyroid invasion, lymph node metastasis, and multi-focality of PTC. FAP and α-SMA demonstrated better performance in this regard. Multivariate logistic regression analysis and receiver operating characteristic(ROC) curve analysis showed that high immunoreactivity scores of FAP and α-SMA were risk factors for poor clinical pathological features, with good predictive sensitivity and accuracy.Conclusion:Strong expression of CAFs was the risk factor for extrathyroid invasion, lymph node metastasis, and mutli-focality of PTC. FAP has the highest clinical value compared with other CAFs marker proteins.

A 41-year-old female patient took decoction of Chinese medicine (containing 10 g of Fructus Lycii, 10 g of Radix Ginseng Rubra, and 15 g of Cortex Acanthopanax Radicis) by herself due to trigeminal neuralgia. After about 6 hours of medication, the patient developed palpitate suddenly, woke up in sleep, accompanied by dizziness. Her blood pressure was 95/63 mmHg. The electrocardiogram showed atrial fibrillation, and ventricular rate was 45 beats/min. Symptomatic treatments such as elevation of hypertension and improvement of myocardial metabolism were given, but the patient′s symptoms were not improved. After that, she developed nausea and vomiting, her heart rate decreased to 35 beats/min, and blood pressure decreased to 87/36 mmHg. Electrocardiogram showed junctional escape rhythm and T-wave change. Electrocardiogram monitoring and continuous oxygen inhalation, and symptomatic and supportive treatments such as continuous IV pumping of dopamine and dobutamine, and polarized solution were given. Eight days after treatment, the patient′s condition was improved. Electrocardiogram showed sinus rhythm. The patient sent the traditional Chinese medicine to a professional institution for identification, and found that it contained Cortex Periplocae, while the original prescription was Cortex Acanthopanax Radicis. Therefore, it is considered that the patient′s arrhythmia was caused by mistakenly use of excessive Cortex Periplocae.
