ObjectiveTo evaluate the larvicidal effect of ultrasonic waves against Aedes albopictus larvae at various exposure parameters (distance and time), and to preliminarily investigate the effects of different containers (water volume and depth) and ultrasonic devices on the larvicidal efficacy, so as to provide experimental evidence for the application of ultrasound-based mosquito control technology. MethodsUnder controlled laboratory conditions, two commercially available ultrasonic devices [40 kHz/300 W and (50±5) kHz/70 W] were used to systematically examine the effects of exposure distance (20, 40, 60, 80, and 100 cm), exposure duration (1, 3, 6, 15 and 60 min), larval instar(Ⅰ‒Ⅱ and Ⅲ‒Ⅳ), and container type on the immediate mortality of Aedes albopictus larvae collected from urban areas of Shanghai. Statistical analysis of the mortality rates of larvae among different experimental groups was performed using the chi-square test. ResultsUltrasonic exposure exerted a detectable larvicidal effect against Aedes albopictus larvae of all instars. For early-instar larvae, exposure time significantly affected mortality at all tested distances (20, 40, 60, 80 and 100 cm), with χ² values ranging from 25.57 to 32.74 ( all P<0.001). No significant distance effect was observed in the first and second instar larvae after short-term exposure (1 and 3 min; P>0.05). However, a distance-dependent effect emerged from 6 min onward (P<0.05). During short-term exposure (1 min and 3 min) at close range (20 cm and 40 cm), the immediate mortality of the third and fourth instar larvae was higher than that of the first and second instar larvae. Conversely, during prolonged exposure (15 min and 60 min), the first and second instar larvae exhibited significantly higher mortality than that of the third and fourth instar larvae. These results indicated that larval mortality was jointly influenced by exposure duration and distance. Preliminary experiments indicated that larvicidal efficacy in shallow water was lower than that in deep water. No significant difference in larvicidal effect was observed between the two ultrasonic devices with different frequencies and power outputs. ConclusionUnder laboratory conditions, ultrasound can effectively kill Aedes albopictus larvae, and the larvicidal effect is jointly influenced by larval instar, exposure distance, and aquatic environment. Compact ultrasonic devices show potential for field application in biological mosquito control.

ObjectiveTo explore the clinical potential of magnetic resonance elastography (MRE) for assessing the stiffness of common intracranial tumors. MethodsA retrospective analysis was conducted on 47 patients with brain tumors who underwent surgical treatment at The First Affiliated Hospital of Sun Yat-sen University between April 2023 and September 2024. The cohort included 10 cases of glioma, 12 cases of vestibular schwannoma, and 25 cases of meningioma. All patients underwent multiparameter MRI and MRE preoperatively. After co-registering MRE images with contrast-enhanced 3D T1-weighted images, three regions of interest (ROIs) were placed in the areas of maximum and minimum tumor stiffness respectively to measure the shear stiffness values, and the mean was calculated as the average shear stiffness. Additionally, one ROI was placed in the white matter and one in the grey matter of the posterior horn of the lateral ventricle at the basal ganglia level to obtain normal reference values. A neurosurgeon, blind to the MRE results, graded the intraoperative tumor stiffness based on surgical videos using a 5-point scale (1: soft; 5: hard). Intraclass correlation coefficient (ICC) was used to assess inter-observer consistency. Analysis of variance (ANOVA) and nonparametric tests were employed to compare the differences of shear stiffness values between groups. Spearman correlation analysis was used to examine the correlation between elasticity values and clinicopathological parameters. The discriminatory efficacy of shear stiffness values for tumor types was evaluated with receiver operating characteristic (ROC) curves. ResultsThe ICCs for elasticity values measured by two physicians in the hardest and softest tumor areas were 0.868 and 0.831, respectively (both P< 0.01). The maximum, minimum, and average shear stiffness values of meningiomas[(1.91±0.28) m/s, (1.66±0.25) m/s, (1.78±0.26) m/s, respectively] were significantly higher than those of gliomas[(1.59±0.23) m/s, (1.42±0.23) m/s, (1.50±0.22) m/s, respectively (P<0.05)]. The shear stiffness values of vestibular schwannomas[(1.70±0.30) m/s, (1.51±0.23) m/s, (1.61±0.26) m/s, respectively) were lower than those of meningiomas and higher than those of gliomas, but these differences were not statistically significant (both P>0.05). The shear stiffness values of white matter were significantly higher than that of grey matter[(1.63±0.08) m/s vs. (1.39±0.12) m/s, P<0.05)]. In the overall sample, the maximum, minimum, and average shear stiffness values were significantly positively correlated with the intraoperative hardness grade (rs = 0.591, rs = 0.541, rs = 0.571, respectively; all P<0.001), negatively correlated with WHO grade (rs = -0.458, rs = -0.458, rs = -0.480, respectively; all P<0.01), but showed no correlation with Ki-67 (all P>0.05). ConclusionMRE can be used to assess the stiffness of intracranial tumors and to some extent differentiate between tumor types, which aids in formulating more individualized preoperative surgical plans.
3.Policy analysis of family-school-society collaboration mechanisms for promoting students physical and mental health
Chinese Journal of School Health 2026;47(9):1240-1245
Objective:
To analyze the text structure, temporal evolution, and mechanism related shortcomings of policies related to family-school-society collaboration in promoting students physical and mental health in China, thereby providing a reference for improving collaborative mechanisms in the context of health promoting school development.
Methods:
The PKULAW Laws and Regulations Database was used as the data source. A total of 115 relevant policy documents issued by relevant departments from the founding of the People s Republic of China to May 7, 2026, were included. Drawing on the adolescent health policy analysis framework and adapting it to the Chinese contexts of family-school-society collaborative education, health promoting school development, and interdepartmental collaborative governance, policy text analysis was conducted. Multi label coding was applied to 629 semantic units, and fractional counting was used to calculate the weights of 6 main dimensions and 31 subdimensions and to describe the dimensional composition of the policies and its changes over time.
Results:
Policies related to family-school-society collaboration in promoting students physical and mental health gradually evolved from early principle based collaboration centered on the ideological and moral development of minors into institutional arrangements supported by the Healthy China initiative, the legal institutionalization of family education, collaborative education mechanisms, and health promoting school development. Among the 6 main dimensions, policy features and costs accounted for 54.8% of the total weight, followed by implementation considerations (22.9%), monitoring and evaluation (9.5%), policy appropriateness (5.6%), inclusion and coverage (4.8%), and participatory approach (2.5%). At the subdimension level, proposed interventions, target population characteristics, intersectoral linkages, consideration of adolescents social ecology, and goal setting accounted for 18.7%, 16.0%, 12.0%, 9.6%, and 9.4% of the total weight, respectively, whereas adolescent participation and the incorporation of young people s voices accounted for only 0.3% and 0.1% , respectively. These findings indicated that the policy texts focused primarily on problem identification, target population specification, and implementation arrangements, while provisions concerning students active participation, identification of differentiated needs, and support from disaggregated data remained relatively limited.
Conclusions
China has established a policy framework for family-school-society collaboration in promoting students physical and mental health that emphasizes goal setting, responsibility division, and organizational implementation, while gradually extending to specific health promotion tasks. Nevertheless, policy provisions concerning students active participation, the identification of differentiated needs, stratified and category specific monitoring, and the use of evaluation feedback require further specification.
4.Related factors and collaborative action framework of multi-disease co-prevention in children and adolescents
Chinese Journal of School Health 2026;47(9):1364-1368
Abstract
The cooccurrence of multi disease among children and adolescents has become increasingly prominent, necessitating a shift from "single disease separate treatment" to "multi disease co prevention". Focusing on four common health problems in children and adolescents, namely, myopia, depression, overweight/obesity, and spinal abnormalities, the paper systematically reviews the association between four categories of factors, society, environment, family, and individual behavior, and the co occurrence of the aforementioned health problems. The findings indicate that particulate matter 2.5 exposure, light at night, physical inactivity, excessive screen time, and unhealthy diet constitute the primary cross dimensional risk network. Based on these findings, the paper proposes a collaborative action framework involving family, school, and society, emphasizing systematic strategies ranging from upstream environmental governance to downstream behavioral intervention, so as to provide evidence for the practice and policy making of multi disease co-prevention in children and adolescents.

Shengyutang is a famous classical formula of tonic, which is made from Siwutang with Ginseng Radix et Rhizoma and Astragali Radix. It is included in the Catalogue of Ancient Famous Classical Formulas(The First Batch). Based on the Principles of Key Information Research of Ancient Famous Classical Formulas, this paper used bibliometrics to sort out and research the key information of Shengyutang in the aspects of history, composition, origin and processing, dosage, decocting method, efficacy and indications. After research, it has been found that this formula was first recorded in Lanshi Micang written by LI Dongyuan during the Jin dynasty, composed of Rehmanniae Radix, Rehmanniae Radix Praeparata, Chuanxiong Rhizoma, Ginseng Radix et Rhizoma, Astragali Radix and Angelicae Sinensis taproot. The name of the formula passed down through generations was relatively unified, with clear origins and veins. In later generations, this formula was the mainstream, and adjustments were made to the dosage and composition according to the indication. In the formula, Astragalus membranaceus var. mongholicus was selected as the origin of Astragali Radix, and the origins of other medicinal materials were consistent with the 2020 edition of Chinese Pharmacopoeia. Except for Rehmanniae Radix Praeparata, the other medicinal materials were made from raw products, and the dosage form was boiled powder. According to the measurement standard in the Jin dynasty, the recommended usage and dosage were 1.24 g of Rehmanniae Radix, Rehmanniae Radix Praeparata, Chuanxiong Rhizoma, Ginseng Radix et Rhizoma each, 2.07 g of Astragali Radix and Angelicae Sinensis taproot each, crushed into coarse particles that pass through the 4 mesh sieve but can't pass through the 10 mesh sieve, added 1 200 mL of water and boiled to 300 mL, and removed the residue. Shengyutang has the functions of tonifying Qi and blood, and blood intake, treating various sores, and restlessness and insomnia caused by excessive blood flow. In ancient times, this formula was widely used in the treatment of surgical sores, gynecological diseases, deficiency syndrome, etc. In modern clinical practice, it is mostly used to treat gynecological, neurological, musculoskeletal, hematological diseases caused by Qi and blood deficiency. In this paper, the key information of Shengyutang was researched by reviewing relevant ancient literature, in order to provide reference for the modern application and development of this formula.
6.Association between mental health and muscle strength among Chinese adolescents aged 13-18
Chinese Journal of School Health 2025;46(9):1232-1236
Objective:
To explore the association between mental health and muscle strength among Chinese adolescents aged 13- 18, providing a theoretical foundation and intervention strategies for mental health promotion.
Methods:
Data were obtained from the 2019 Chinese National Survey on Students Constitution and Health, including 98 631 Chinese adolescents aged 13- 18. Psychological distress was assessed by using the Kessler Psychological Distress Scale (K10), and mental well being was measured with the Warwick-Edinburgh Mental Well being Scale (WEMWBS). Based on the gender and age specific Z scores of various test items [grip strength, standing long jump, pull ups (for males), and sit ups (for females)], muscle strength index (MSI) was constructed to evaluate the comprehensive level of muscle strength in adolescents. According to the Dual factor Model (DFM) of mental health, participants were categorized into four groups:troubled, symptomatic but content, vulnerable, and complete mental health. Gender differences were analyzed by using Chi-square tests, trends were tested with Cochran-Armitage tests, and multinomial Logistic regression models were applied to assess associations between muscle strength and mental health among adolescents.
Results:
In 2019, 37.4% of Chinese adolescents aged 13-18 were reported of high mental distress, and 59.9% were reported of low mental well being. Boys had significantly lower rates of high mental distress (35.3%) and low mental well being (55.6%) compared to girls (39.4%, 64.3%), and the differences were of statistical significance ( χ 2=176.13, 780.42, both P <0.05). In 2019, the rate of complete mental health among adolescents showed a downward trend with increasing age ( χ 2 trend = 258.47) and a gradual upward trend with increasing muscle strength levels ( χ 2 trend =123.14),and both boys and girls exhibited similar trends ( χ 2 trend =103.83, 168.46; 57.00 , 67.34) (all P <0.05). The results of the unordered multiclass Logistic regression model showed that after controlling for confounding factors such as age and gender, when the completely pathological group as a reference, for every 1 unit increase in MSI in adolescents, the likelihood of being in a completely mental health state increased by 29% ( OR = 1.29); for every unit increase in the Z-score for pull ups, the likelihood of being in a completely mental health state increased by 6% ( OR =1.06) among boys; for every 1 unit increase in sit up Z score, the likelihood of being in a completely mental health state increased by 19% ( OR =1.19) among girls (all P <0.05).
Conclusions
The mental health status of Chinese adolescents is not good enough. Muscle strength is positively associated with mental health.

Nucleotide-binding oligomerization domain (NOD)-like receptor protein 3 (NLRP3) is a cytosolic pattern recognition receptor that recognizes multiple pathogen-associated molecular patterns and damage-associated molecular patterns. It is a cytoplasmic immune factor that responds to cellular stress signals, and it is usually activated after infection or inflammation, forming an NLRP3 inflammasome to protect the body. Aberrant NLRP3 inflammasome activation is reportedly associated with some inflammatory diseases and metabolic diseases. Recently, there have been mounting indications that NLRP3 inflammasomes play an important role in liver injuries caused by a variety of diseases, specifically hepatic ischemia/reperfusion injury, hepatitis, and liver failure. Herein, we summarize new research pertaining to NLRP3 inflammasomes in hepatic injury, hepatitis, and liver failure. The review addresses the potential mechanisms of action of the NLRP3 inflammasome, and its regulation in these liver diseases.

Stresses induced by the deficiency or excess of trace mineral elements, such as manganese (Mn), represent a common limiting factor for the production of crops like Brassica napus. To identify key genes involved in Mn allocation in B. napus and elucidate the underlying mechanisms, a member of the metal tolerance protein (MTP) family obtained in the previous screening of cDNA library of B. napus under Mn stress was selected as the research subject. Based on the sequence information and phylogenetic analysis, it was named as BnMTP10. It belongs to the Mn-cation diffusion facilitator (CDF) subfamily. Expression of BnMTP10 in yeast significantly improved the tolerance of transformants to excessive Mn and iron (Fe) and reduced the accumulation of Mn and Fe. However, the yeast transformants exhibited no significant changes in tolerance to excess cadmium, boron, aluminum, zinc, or copper. The qRT-PCR results demonstrated that the flowers of B. napus had the highest expression of BnMTP10, followed by roots and leaves. Subcellular localization studies revealed that BnMTP10 was localized in the endoplasmic reticulum (ER). Compared with wild-type plants, transgenic Arabidopsis overexpressing BnMTP10 exhibited enhanced tolerance to excessive Mn stress but showed no significant difference under Fe stress. Correspondingly, under excessive Mn stress, the Mn content in the roots of transgenic Arabidopsis increased significantly. However, under excessive Fe stress, the Fe content in transgenic Arabidopsis did not alter significantly. According to the results, we hypothesize that BnMTP10 may alleviate excessive Mn stress in plants by mediating Mn transport to the ER. This study facilitated our understanding of efficient mineral nutrients, and provided theoretical foundations and gene resources for breeding B. napus.
