ObjectiveTo compare the mosquito capture efficacy of the BG-trap method and the light trap method, and to explore the precisely applicable scenarios for the two monitoring approaches. MethodsFrom May to October 2024, one BG-trap and one light trap were placed at eight monitoring sites, with a distance of over 10 meters between the two traps at each site. Surveillance was performed twice monthly to compare the two surveillance methods in terms of mosquito species composition, the proportional distribution of female mosquitoes across different habitats, and seasonal fluctuations in mosquito density. ResultsThere were statistically significant differences in mosquito species composition (χ²=60.61, P<0.001) and female mosquito species composition (χ²=37.12, P<0.001) between the BG-trap method and the light trap method, with the BG-trap method capturing a higher proportion of Aedes albopictus than the light trap method. The average density of mosquitoes monitored by the BG-trap method [13.36 mosquitoes·(trap·night)^-1] was higher than that monitored by the light trap method[4.70 mosquitoes·(trap·night)^-1]. There was statistically significant difference (t=6.70, P<0.001) for the mosquito density between the two methods, and there was a significant positive correlation (r=0.909, P<0.001) for the mosquito density indices between the two methods. The average density of female mosquitoes monitored by the BG-trap method [8.18 mosquitoes·(trap·night)^-1] was higher than that monitored by light trap method [3.36 mosquitoes·(trap·night)^-1]. There was statistically significant difference (t=6.00, P<0.001) for the female mosquito density between the two methods, and there was a significant positive correlation (r=0.929, P<0.001) for the female mosquito density indices between the two methods. In the four different habitats, the constituent ratio of mosquitoes and female mosquitoes monitored by the BG-trap method in descending order were urban residential area (43.80% and 40.25%), rural farm households (35.55% and 38.60%), hospital (12.70% and 12.87%), and park (7.95% and 8.28%), while the constituent ratio of mosquitoes and female mosquitoes monitored by the light trap method in descending order were rural farm households (34.37% and 43.34%), hospital (33.26% and 30.03%), park (17.96% and 15.17%), and urban residential area (14.41% and 11.46%). In different habitats, there were statistically significant differences for mosquito composition ratios (χ²=189.64, P<0.001) and female mosquito composition ratios (χ²=109.15, P<0.001) between the two monitoring methods. ConclusionThe BG-trap method offers advantages such as simple operation, compact equipment, and high efficiency, with a higher trapping rate for Aedes albopictus compared to the light trap method. In routine monitoring, the BG-trap method can serve as a supplement to the light trap method, while for emergency monitoring of Aedes albopictus in dengue fever outbreak areas and mosquito collection efforts, the BG-trap method is more effective than the light trap method.

BACKGROUND:In our previous experiments,it was found that transplantation of young adipose stem cells into aged mice would have weight loss effect and improve the inflammatory state in aged mice. Therefore,we speculate that insulin-like growth factor 1 may play an important role in aging and obesity. OBJECTIVE:To explore the anti-obesity effect of insulin-like growth factor 1 in naturally aging mice. METHODS:(1) Bioinformatics analysis:Sequencing of adipose tissue from obese patients in the GEO database and transcriptomic sequencing of young mouse adipose stem cells and old adipose stem cells were conducted to analyze insulin-like growth factor 1 expression. (2) Animal experiment verification:Six young C57BL/6J mice and twelve aged C57BL/6J mice (20 months old) were selected. Abdominal adipose tissue and serum insulin-like growth factor 1 expression in young and aged mice were examined by ELISA and qRT-PCR. All the 12 aged mice were randomly divided into two groups with 6 mice in each group:the experimental group was given insulin-like growth factor 1 (50 μg/kg) for 4 continuous weeks,while the control group was given the same amount of phosphate buffer saline. The body mass changes of mice were monitored regularly,glucose tolerance was measured at the end of the experiment,and serum inflammatory factors and inflammatory factors in abdominal white adipose tissue of mice were detected by ELISA. Hematoxylin-eosin staining was used to observe pathological changes in the mouse liver,kidney and abdominal white adipose tissue. The mRNA expression levels of inflammatory factors and PI3K-Akt signaling pathway in abdominal white adipose tissue of mice were detected by qRT-PCR.RESULTS AND CONCLUSION:Obese patients showed lowly expressed insulin-like growth factor 1 in adipose tissue,but the expression of insulin-like growth factor 1 increased after weight loss surgery. Insulin-like growth factor 1 expressed lowly in aged adipose stem cells. Insulin-like growth factor 1 also showed a low expression in adipose tissue and serum of aged mice. Injection of insulin-like growth factor 1 protein could significantly reduce the body mass of aged mice and improve insulin resistance. Pathological sections of the liver of aged mice revealed fat accumulation. After injection of insulin-like growth factor 1 protein,fat accumulation was significantly improved and the size of fat droplets in adipose tissue was significantly reduced. Insulin-like growth factor 1 injection significantly reduced the expression levels of serum tumor necrosis factor α,interleukin 1β,and interleukin 6 in aged mice,and significantly increased the expression of PI3K-AKT signaling pathway in adipose tissue of aged mice. To conclude,exogenous insulin-like growth factor 1 can reduce body mass,reduce fat droplet size in adipose tissue,and improve liver fat accumulation in aged mice,thereby improving their inflammatory status. Exogenous insulin-like growth factor 1 may activate the PI3K-AKT signaling pathway to improve the inflammatory symptoms in aged mice,thereby improving obesity in naturally aging mice.

Objective:To construct a risk prediction model for non-suicidal self-injury (NSSI) in adolescents with mood disorders, providing a basis for identifying and intervening in high-risk patients.Methods:A convenience sampling method was used to retrospectively analyze 724 adolescent patients with mood disorders admitted to the open ward of Qingdao Mental Health Center from January 2019 to July 2023. Patients admitted from January 2019 to December 2022 (641 cases) were randomly divided into a modeling group and an internal validation group in a 7∶3 ratio, while patients admitted from January to July 2023 (83 cases) were used as an external validation group. A binary multivariate logistic regression analysis was used to construct a nomogram prediction model for NSSI risk in adolescents with mood disorders. The predictive performance of the model was evaluated using the area under the curve (AUC), sensitivity, and specificity.Results:There were 179 males and 545 females, aged 15 (14, 17) years old. Among the 724 patients, 449 were in the modeling group, 192 in the internal validation group, and 83 in the external validation group. The incidence of NSSI in the modeling group was 32.96% (148/449). Reduced food intake ( OR=10.980, 95% CI 4.462-27.017), passive contact ( OR=4.681, 95% CI 1.986-11.031), Hamilton Depression Rating Scale-17 score >17 ( OR=12.235, 95% CI 4.657-32.141), Hamilton Anxiety Rating Scale score>15 ( OR=27.888, 95% CI 8.700-124.630), Insomnia Severity Index score >15 ( OR=6.357, 95% CI 2.257-17.899), and higher levels of past self-injury ( OR=1.663, 95% CI 1.428-1.935) were independent risk factors for NSSI in adolescents with mood disorders (all P<0.05). The AUC of the nomogram model based on these six factors was 0.973, with a sensitivity of 0.94 and a specificity of 0.89. Conclusions:The risk prediction model for NSSI in adolescents with mood disorders has good discrimination, accuracy, and practicality, and can help identify high-risk NSSI populations among adolescents with mood disorders.

OBJECTIVE To establish the quality standard of Triadica cochinchinensis and to perform the acute toxicity study. METHODS Appearance properties, powder microscopic identification, and thin-layer chromatography(TLC) identification were researched. The specific chromatogram was established by HPLC. The content of cadmium(Cd), lead(Pb), arsenic(As), copper(Cu), and mercury(Hg) was determined by inductively coupled plasma-mass spectrometry(ICP-MS). Acute toxicity was studied by maximum dose. RESULTS The outer skin of herbs was dark brown, and the inner surface was light yellow brown and fibrous. Besides, crystal sheath fiber was common, and calcium oxalate clusters arranges in rows. In the TLC diagram of the test product, the fluorescent spots of the same color were displayed at the corresponding position of the control product(scopoletin, isofraxidin). Five common peaks were calibrated in the characteristic map and the three characteristic peaks(scopoletin, isofraxidin, dimethylfraxetin) were recognized. The content of the measured heavy metal elements was lower than the national limit standard. The linear correlation coefficient was R2 > 0.999. The precision, stability, repetitive RSD were < 10%. The average recovery rate of the added sample was 80%−120%, and the RSD was < 10%. The maximum dose of the acute toxicity test was 184.09 g·kg−1. The 14 d internal body mass, food intake, organ-body ratios, the serum glutamic pyruvic transaminase, glutamic oxaloacetic transaminase, blood urea nitrogen, and creatinine were not significantly different by comparing with the normal controls. Therefore, no significant toxicity was observed. CONCLUSION The established standard can provide a reference for evaluating the quality of Triadica cochinchinensis. The heavy metal content of ten batches of medicinal materials is within the safe range. Acute toxicity test show that there is no obvious significant adverse teactions after oral administration, and the safe dose range is large, which can provide a reference for the subsequent development and utilization.

Detailed characterizations of genomic alterations have not identified subtype-specific vulnerabilities in adult gliomas. Mapping gliomas into developmental programs may uncover new vulnerabilities that are not strictly related to genomic alterations. After identifying conserved gene modules co-expressed with EGFR or PDGFRA (EM or PM), we recently proposed an EM/PM classification scheme for adult gliomas in a histological subtype- and grade-independent manner. By using cohorts of bulk samples, paired primary and recurrent samples, multi-region samples from the same glioma, single-cell RNA-seq samples, and clinical samples, we here demonstrate the temporal and spatial stability of the EM and PM subtypes. The EM and PM subtypes, which progress in a subtype-specific mode, are robustly maintained in paired longitudinal samples. Elevated activities of cell proliferation, genomic instability and microenvironment, rather than subtype switching, mark recurrent gliomas. Within individual gliomas, the EM/PM subtype was preserved across regions and single cells. Malignant cells in the EM and PM gliomas were correlated to neural stem cell and oligodendrocyte progenitor cell compartment, respectively. Thus, while genetic makeup may change during progression and/or within different tumor areas, adult gliomas evolve within a neurodevelopmental framework of the EM and PM molecular subtypes. The dysregulated developmental pathways embedded in these molecular subtypes may contain subtype-specific vulnerabilities.

Epilepsy is a common chronic neurological disease, and its comorbidity has attracted more attention.The proportion of epileptic children with mental disorders is also increasing year by year.Among them, children with epilepsy have more depression and anxiety disorders.Repeated seizures can easily cause depression and anxiety, and depression and anxiety can also induce epilepsy, thus the two affect each other.The assessment, screening, diagnosis and intervention of comorbid depression and anxiety in children with epilepsy have become an important part of clinical practice.This review summarized the relationship between epilepsy and depression and anxiety disorders in children, and its research progress on pathogenesis, clinical diagnosis, evaluation and treatment.

Objective:To explore the value of the static and dynamic pelvic floor MRI and diffusion tensor imaging (DTI) in evaluating the morphology and function of urethra in patients with stress urinary incontinence (SUI).Methods:From July 2020 to February 2021, a total of 28 patients with SUI and 45 age-matched healthy controls were prospectively collected at the First Affiliated Hospital of Zhengzhou University. The static and dynamic pelvic floor MRI and DTI were performed for all subjects. The thickness of internal and external sphincter of middle urethra were measured on static MRI images. The functional urethral length (FUL) was measured both on static and maximal strain phase of dynamic MRI images, then the difference of FUL was calculated. The presence of bladder neck funneling and urethra opening were observed on static and dynamic MRI. The muscle fiber bundle image of urethral sphincter complex was obtained by post-processing of DTI original images. The anisotropy fraction (FA), apparent diffusion coefficient (ADC) and three eigenvalues (λ1, λ2, λ3) of annular sphincter and central longitudinal muscle in middle urethra were measured. The independent sample t test and chi-square test were used to analyse the difference of measured parameters in MRI, parameters of DTI and imaging signs between the two groups. Results:Compared with healthy controls, the SUI patients showed that the thickness of external sphincter in middle urethral and FUL in static status and maximal strain phase were significantly decreased ( t=-3.95, -5.72, -8.41, all P<0.001), the difference of FUL between static status and maximal strain phase was significantly increased ( t=4.41, P<0.001). The positive rate of bladder neck funneling in static status and maximal strain phase, urethral opening in maximal strain phase of SUI group increased significantly (χ2=23.09 , 22.25, 26.59, all P<0.001). In SUI group, the FA value of middle urethral annular sphincter decreased significantly ( t=-3.48, P=0.001), while the ADC, λ2 and λ3 values increased significantly ( t=3.19, 2.15 , 2.06, and P=0.002, 0.038 , 0.046, respectively). There was no significant difference in DTI parameters of middle urethral longitudinal muscle between the two groups (all P>0.05). Conclusions:Static and dynamic MRI and DTI techniques can objectively evaluate the changes of urethral morphology and function of SUI patients. The thinning of the external sphincter in the middle urethra, shortening of the FUL and the destruction of the microstructure of the annular sphincter fiber bundle were the main alterations of SUI patients.

Acute-on-chronic liver failure (ACLF) is a life-threatening disease with a high risk of multiple organ failure, sepsis, and death. ACLF activates innate and acquired immune responses in human body and thus leads to the progression of persistent systemic inflammatory response syndrome and multiple organ dysfunction, leading to the high mortality rate of this disease. Dysregulated immune response plays a key role in disease progression, and immunotherapy may help to target immune-mediated organ damage and inhibit the progression of liver failure. This article reviews the role and mechanism of drugs and means with a potential immune regulatory effect in ACLF, in order to provide a reference for immunotherapy for ACLF.
