Objective: To investigate the correlation of emotional and behavioral problems with sleep problems in children with cerebral palsy, so as to provide reference for intervention of emotional and behavioral problems in children. Methods: A cross sectional survey was conducted, and 402 children aged 6-18 with cerebral palsy who were adopted by social welfare institutions in Guangzhou City from January 2023 to January 2024 were selected to investigate their full time nurses. The Parents Strengths and Difficulties Questionnaire (SDQ) was used to assess the emotional and behavioral problems of children with cerebral palsy, and the Children s Sleep Habits Questionnaire (CSHQ) was used to assess sleep problems. Multiple linear regression analysis was used to analyze the correlation between the sleep problem of children with cerebral palsy and the emotional and behavioral problems. Results: The prevalence of emotional and behavioral difficulties among children with cerebral palsy was 15.7%. The median sleep problem score of children with emotional and behavioral problems [37.0(36.0, 41.0)] was significantly higher than that of children without emotional and behavioral [35.0(34.0, 36.0)] ( Z =-5.74, P <0.01). The results of multiple linear regression analysis showed that after adjusting covariables such as age, gender, cerebral palsy classification, language retardation, visual impairment and epilepsy, the total sleep problem score of children with cerebral palsy was positively correlated with the total difficulty score ( β= 0.28, 95%CI =0.17-0.34, P <0.05). Conclusions Sleep problems in children with cerebral palsy are associated with emotional and behavioral difficulties. Understanding of the management of sleep problems in children with cerebral palsy should be enhanced to reduce the incidence of emotional and behavioral problems in children with cerebral palsy.

Objective To systematically evaluate the risk prediction model of anastomotic fistula after radical resection of esophageal cancer, and to provide objective basis for selecting a suitable model. Methods A comprehensive search was conducted on Chinese and English databases including CNKI, Wanfang, VIP, CBM, PubMed, EMbase, Web of Science, The Cochrane Library for relevant studies on the risk prediction model of anastomotic fistula after radical resection of esophageal cancer from inception to April 30, 2023. Two researchers independently screened literatures and extracted data information. PROBAST tool was used to assess the risk of bias and applicability of included literatures. Meta-analysis was performed on the predictive value of common predictors in the model with RevMan 5.3 software. Results A total of 18 studies were included, including 11 Chinese literatures and 7 English literatures. The area under the curve (AUC) of the prediction models ranged from 0.68 to 0.954, and the AUC of 10 models was >0.8, indicating that the prediction performance was good, but the risk of bias in the included studies was high, mainly in the field of research design and data analysis. The results of the meta-analysis on common predictors showed that age, history of hypertension, history of diabetes, C-reactive protein, history of preoperative chemotherapy, hypoproteinemia, peripheral vascular disease, pulmonary infection, and calcification of gastric omental vascular branches are effective predictors for the occurrence of anastomotic leakage after radical surgery for esophageal cancer (P<0.05). Conclusion The study on the risk prediction model of anastomotic fistula after radical resection of esophageal cancer is still in the development stage. Future studies can refer to the common predictors summarized by this study, and select appropriate methods to develop and verify the anastomotic fistula prediction model in combination with clinical practice, so as to provide targeted preventive measures for patients with high-risk anastomotic fistula as soon as possible.

ObjectiveNeuroinflammation plays a crucial role in both the onset and progression of ischemic stroke, exerting a significant impact on the recovery of the central nervous system. Excessive neuroinflammation can lead to secondary neuronal damage, further exacerbating brain injury and impairing functional recovery. As a result, effectively modulating and reducing neuroinflammation in the brain has become a key therapeutic strategy for improving outcomes in ischemic stroke patients. Among various approaches, targeting immune regulation to control inflammation has gained increasing attention. This study aims to investigate the role of in vitro induced regulatory T cells (Treg cells) in suppressing neuroinflammation after ischemic stroke, as well as their potential therapeutic effects. By exploring the mechanisms through which Tregs exert their immunomodulatory functions, this research is expected to provide new insights into stroke treatment strategies. MethodsNaive CD4⁺ T cells were isolated from mouse spleens using a negative selection method to ensure high purity, and then they were induced in vitro to differentiate into Treg cells by adding specific cytokines. The anti-inflammatory effects and therapeutic potential of Treg cells transplantation in a mouse model of ischemic stroke was evaluated. In the middle cerebral artery occlusion (MCAO) model, after Treg cells transplantation, their ability to successfully migrate to the infarcted brain region and their impact on neuroinflammation levels were examined. To further investigate the role of Treg cells in stroke recovery, the changes in cytokine expression and their effects on immune cell interactions was analyzed. Additionally, infarct size and behavioral scores were measured to assess the neuroprotective effects of Treg cells. By integrating multiple indicators, the comprehensive evaluation of potential benefits of Treg cells in the treatment of ischemic stroke was performed. ResultsTreg cells significantly regulated the expression levels of both pro-inflammatory and anti-inflammatory cytokines in vitro and in vivo, effectively balancing the immune response and suppressing excessive inflammation. Additionally, Treg cells inhibited the activation and activity of inflammatory cells, thereby reducing neuroinflammation. In the MCAO mouse model, Treg cells were observed to accumulate in the infarcted brain region, where they significantly reduced the infarct size, demonstrating their neuroprotective effects. Furthermore, Treg cell therapy notably improved behavioral scores, suggesting its role in promoting functional recovery, and increased the survival rate of ischemic stroke mice, highlighting its potential as a promising therapeutic strategy for stroke treatment. ConclusionIn vitro induced Treg cells can effectively suppress neuroinflammation caused by ischemic stroke, demonstrating promising clinical application potential. By regulating the balance between pro-inflammatory and anti-inflammatory cytokines, Treg cells can inhibit immune responses in the nervous system, thereby reducing neuronal damage. Additionally, they can modulate the immune microenvironment, suppress the activation of inflammatory cells, and promote tissue repair. The therapeutic effects of Treg cells also include enhancing post-stroke recovery, improving behavioral outcomes, and increasing the survival rate of ischemic stroke mice. With their ability to suppress neuroinflammation, Treg cell therapy provides a novel and effective strategy for the treatment of ischemic stroke, offering broad application prospects in clinical immunotherapy and regenerative medicine.

In order to provide basic information for the utilization and development of famous classical formulas containing Bletillae Rhizoma， this article systematically analyzes the historical evolution of the name， origin， harvesting and processing of Bletillae Rhizoma by reviewing the ancient materia medica， prescription books， medical books and modern literature. The research results showed that Baiji（白及） was the main name， some scholars took Baiji（白芨） as its main name， and there were many other names such as Baiji（白给）， Baigen（白根）， Baiji（白苙）. The mainstream source of Bletillae Rhizoma was the tubers of Bletilla striata， and drying， large， white， solid， root-free and skin removed completely were the good quality standards. With the promotion of wild to cultivated medicinal materials， there were certain differences between their traits， and the quality evaluation indexes should be adjusted accordingly. The origin of records in the past dynasties was widely distributed， with Guizhou and Sichuan having high production and good quality in modern times. The harvesting period is mostly in spring and autumn， and harvested in autumn was better. The processing and processing technology is relatively simple， and it was used fresh or powdered in past dynasties， while it is mainly sliced for raw use in modern times. Based on the results， it is suggested that the tubers of Bletilla striata of Orchidaceae should be used in the famous classical formulas， and it should be uniformly written as Baiji（白及）. And if the original formula indicates the requirement of processing， it should be operated according to the requirement， if the requirement of processing is not indicated， it can be used in raw form as medicine.

In recent years, an increasing number of emerging environmental pollutants have been identified, garnering widespread attention. Many of these pollutants are characterized by their environmental persistence and bioaccumulation, which pose significant threats to both the ecological environment and human health. However, the molecular mechanisms underlying their effects remain unclear, limiting our ability to assess their adverse impacts and develop effective protective measures. The aryl hydrocarbon receptor (AHR) is a ligand-activated transcription factor traditionally known to be activated by dioxins and polycyclic aromatic hydrocarbons (PAHs) and is involved in the metabolism of exogenous chemicals. Recent research has shown that the AHR can be activated by a diverse range of exogenous and endogenous chemicals and participates in various biological processes. Studies have demonstrated that AHR mediates the toxic effects of emerging environmental pollutants such as perfluorooctane sulfonamide (PFOSA) and N-(1,3-dimethylbutyl)-N’-phenyl-p-phenylenediamine quinone (6PPDQ). This paper provided an overview of the AHR activation and the toxic effects induced by emerging environmental pollutants, with a focus on how the AHR activation interacts with multiple signaling pathways. The significance of these interactions in environmental risk assessment and toxicological research was also discussed. We aim to provide a scientific basis for environmental protection and risk assessment.

Background In recent years, a growing number of studies have indicated that perfluorooctanoic acid (PFOA) exposure can impact heart development, though the specific mechanisms remain elusive. The aryl hydrocarbon receptor (AHR) is a critical environmental sensor capable of inducing oxidative stress and cell apoptosis. Objective To explore the role of AHR in the cardiac developmental toxicity of PFOA by using zebrafish embryo as an in vivo model. Methods Zebrafish embryos at 2 h post-fertilization (2 hpf) were exposed to dimethyl sulfoxide (DMSO) control, 1, 10, 100, and 1000 μg·L⁻¹ of PFOA. The AHR inhibitor CH223191 (CH) was added to the high-concentration group (1000 μg·L⁻¹) to form an intervention group. Under a dissecting microscope, the survival rate, mortality rate, heart rate, and heart malformation rate of 72 hpf zebrafish larvae were assessed. The activity of AHR was measured using 7-ethoxyresorufin-O-dealkylation (EROD) staining. The levels of intracellular and mitochondrial ROS in the heart of zebrafish larvae were assessed using dichloro-dihydro-fluorescein diacetate and MitoSOX™ Red, respectively. Apoptosis was examined using acridine orange (AO) staining and Immunofluorescence method. Total RNA was extracted from dissected hearts, and mRNA expression levels of oxidative stress-related genes (sod2, cat) and apoptosis-related gene (p53) were analyzed using quantitative PCR. Results Compared to the DMSO control group, PFOA at even the lowest concentration (1 μg·L⁻¹) increased heart malformation rate (P＜0.05) and reduced heart rate (P＜0.01) in the zebrafish larvae at 72 hpf, and the results showed a clear concentration-response relationship. Adding the AHR inhibitor CH significantly decreased heart malformation rate and restored heart rate to the control group level. The EROD results showed that PFOA at 1000 μg·L⁻¹ increased AHR activity (P＜0.001). Further studies revealed that PFOA caused a dose-dependent increase in intracellular ROS (P<0.001) and an increase in mitochondrial ROS (P<0.001) in the heart region of zebrafish larvae. A high dose of PFOA (1000 μg·L⁻¹) also induced elevated mRNA expression levels of oxidative stress-related genes sod2 and cat (P<0.05). Addition of the AHR inhibitor CH effectively antagonized PFOA-induced (1000 μg·L⁻¹) oxidative stress in the heart of zebrafish larvae (P<0.001). In addition, PFOA exposure induced a concentration-dependent increase in apoptotic bodies in the heart of zebrafish larvae (P<0.05). Moreover, PFOA at 1000 μg·L⁻¹ caused an increase in the cleaved-caspase 3 immunofluorescence signal (P<0.05) as well as overexpression of the apoptosis-associated gene p53 (P<0.001).which were attenuated by the CH supplementation. Conclusion PFOA triggers oxidative stress and apoptosis via AHR activation in the heart of zebrafish larvae, resulting in cardiac defects.
