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.

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.

Background::There is a need for effective and safe therapies for psoriasis that provide sustained benefits. The aim of this study was to assess the efficacy and safety of tildrakizumab, an anti-interleukin-23p19 monoclonal antibody, for treating moderate-to-severe plaque psoriasis in Chinese patients.Methods::In this multi-center, double-blind, phase III trial, patients with moderate-to-severe plaque psoriasis were enrolled and randomly assigned (1:1) to receive subcutaneous tildrakizumab 100 mg or placebo at weeks 0 and 4. Patients initially assigned to placebo were switched to receive tildrakizumab at weeks 12, 16, and every 12 weeks thereafter. Patients in the tildrakizumab group continued with tildrakizumab at week 16, and every 12 weeks until week 52. The primary endpoint was the Psoriasis Area and Severity Index (PASI 75) response rate at week 12.Results::At week 12, tildrakizumab demonstrated significantly higher PASI 75 response rates (66.4% [73/110] vs. 12.7% [14/110]; difference, 51.4% [95% confidence interval (CI), 40.72, 62.13]; P <0.001) and Physician’s Global Assessment (60.9% [67/110] vs. 10.0% [11/110]; difference, 49.1% [95% CI, 38.64, 59.62]; P <0.001) compared to placebo. PASI 75 response continued to improve over time in both tildrakizumab and placebo-switching to tildrakizumab groups, reaching maximal efficacy after 28 weeks (86.8% [92/106] vs. 82.4% [89/108]) and maintained up to 52 weeks (91.3% [95/104] vs. 87.4% [90/103]). Most treatment-emergent adverse events were mild and not related to tildrakizumab. Conclusion::Tildrakizumab demonstrated durable efficacy through week 52 and was well tolerated in Chinese patients with moderate-to-severe plaque psoriasis.Trial registration::ClinicalTrials.gov, NCT05108766.

Objective:To systematically evaluate the effect of cognitive behavioral therapy (CBT) in elderly patients with depression.Methods:The randomized controlled trials on the effect of CBT in elderly patients with depression, published until December 15, 2022, were searched in PubMed, CINHAL, Cochrane Library, China Biology Medicine, China National Knowledge Infrastructure, WanFang Data, and VIP. Two researchers independently screened the literature, extracted data, and used the revised Cochrane risk of bias tool for randomized trials (ROB 2.0) to evaluate the quality of the included studies. Statistical analysis was conducted using Stata 16.0, and the quality of evidence was rated using Appraisal of Guidelines for Research and Evaluation (GRADE) predictor software.Results:A total of 11 randomized controlled trials were included, with a total of 833 elderly patients with depression. Randomized effect models were used to analyze outcome indicators such as depression, anxiety, and quality of life by combining effect quantities. Meta-analysis and GRADE evidence quality showed that compared to the control group, medium quality evidence showed that CBT could relieve depression in elderly depression patients with a statistical difference [ SMD=-1.58, 95% CI (-2.16, -0.99), P<0.05]. Low quality evidence suggested that CBT could alleviate anxiety in elderly depression patients also with a statistical difference [ SMD=-2.25, 95% CI (-4.04, -0.47), P<0.05]. Very low quality evidence indicated that CBT did not significantly improve the quality of life in elderly depression patients compared to conventional or pharmacological treatment [ SMD=-0.09, 95% CI (-2.07, 1.88), P>0.05] . Conclusions:Existing evidence suggests that CBT can alleviate depression and anxiety in elderly depression patients, but its improvement in quality of life is not yet significant. Treatment feedback and forms of CBT may become a research focus in recent years on intervention for elderly depression patients.

Objective:To evaluate the influence of ankle acupuncture on the cognitive impairment caused by sevoflurane in elderly rats and the expression of hippocampal phosphorylated phospholipase Cγ (p-PLCγ).Methods:Fifteen SPF-grade healthy male Sprague-Dawley rats, aged 18 months, weighing 530-600 g, were allocated into 3 groups ( n=5 each) using a random number table method: sham surgery group (S group), cognitive dysfunction group (CD group) and ankle acupuncture group (A group). The cognitive dysfunction model was prepared by inhaling the mixture of 3% sevoflurane and air, with ankle acupuncture applied to the right hind limb 1-3 region for 30 min prior to anesthesia in A group. S group received sham stimulation. Two days later, the cognitive function was assessed using the Morris water maze test. The rats were subsequently sacrificed and hippocampal tissues were collected for microscopic examination of the pathological changes (using HE staining and Nissl staining) and for determination of the expression of p-PLCγ, phosphorylated calcium/calmodulin-dependent protein kinase Ⅱ (p-CaMKⅡ) and phosphorylated inositol-1, 4, 5-trisphosphate receptor (p-IP3R). Results:Compared with S group, the escape latency was significantly prolonged, the number of crossing the original platform quadrant was reduced, and the expression of p-PLCγ, p-CaMKII and p-IP3R was up-regulated in CD group and A group ( P<0.05). Compared with CD group, the escape latency was significantly shortened, the number of crossing the original platform quadrant was increased, and the expression of p-PLCγ, p-CaMKII and p-IP3R was down-regulated in A group ( P<0.05). The pathological changes were significantly reduced in A group compared with CD group. Conclusions:Ankle acupuncture can ameliorate cognitive dysfunction induced by sevoflurane in elderly rats, and the mechanism is related to inhibition of hippocampal p-PLCγ expression.
