ObjectiveTo investigate the effects of Huangqi Jianzhongtang (HQJZ) on macrophage polarization and fat consumption in cancer cachexia (CC) mice. MethodsUltra-performance liquid chromatography-quadrupole/electrostatic field Orbitrap high-resolution mass spectrometry (UPLC-Q-Orbitrap HRMS) was used to control the quality of HQJZ. (1) In vitro experiment: HQJZ-containing serum was prepared, and the optimal concentration was determined by cytotoxicity assay. Mouse monocyte-derived macrophages (RAW264.7) were cultured and randomly divided into six groups, including a blank group, a classically activated macrophages (M1) group, an alternatively activated macrophages (M2) group, a HQJZ + blank group, a HQJZ+M1 group, and a HQJZ + M2 group. The relative expression of macrophage marker genes CD86, inducible nitric oxide synthase (iNOS), CD206, and arginase-1 (Arg1) was detected by real-time quantitative polymerase chain reaction (Real-time PCR ). (2) In vivo experiment: Thirty-two BALB/c mice were randomly divided into a control group, a model group, a medroxyprogesterone acetate (MPA) group, and a HQJZ group. Except for the control group, the other mice were injected with CT-26 colon cancer cells to establish a CC model. Mice in the MPA and HQJZ groups were given MPA (0.13 g·kg-1·d-1) or HQJZ (13.13 g·kg-1·d-1) by gavage, respectively, while mice in the control and model groups were given an equal volume of saline by gavage, with interventions continued for 10 d. Real-time PCR was used to detect the expression of macrophage markers (iNOS, Arg1, CD86, CD206) and fat browning-related genes uncoupling protein 1 (UCP1) and peroxisome proliferator-activated receptor γ (PPARγ) in epididymal adipose tissue. Western blot (WB) was used to detect protein expression levels of UCP1 and PPARγ. Micro-computed tomography (micro-CT) was used to measure residual fat volume, and hematoxylin-eosin (HE) staining was used to assess fat browning and calculate pathological scores. ResultsIn vitro, the dominant effective concentration of HQJZ-containing serum was 12.5%. Real-time PCR results showed that, compared with the blank group, Arg1 expression decreased in the HQJZ+blank group (P<0.05), CD206 showed a downward trend without statistical significance, while iNOS and CD86 expression were significantly increased (P<0.05). Compared with the M1 group, Arg1 and CD206 expression decreased in the HQJZ+M1 group (P<0.05). Compared with the M2 group, CD206 expression decreased in the HQJZ+M2 group (P<0.05), CD86 expression increased significantly (P<0.01). In vivo, Real-time PCR results showed that, compared with the control group, CD86 and CD206 expression levels were significantly increased in the model group (P<0.01). Compared with the model group, CD206 expression in the MPA group was significantly decreased (P<0.01). In the HQJZ group, CD206 was significantly decreased (P<0.01). WB results showed that, compared with the model group, protein expression of UCP1 and PPARγ was significantly reduced in the HQJZ group (P<0.05, P<0.01). micro-CT results showed that the total white fat volume in the HQJZ group was greater than that in the model group (P<0.05). HE staining results showed that pathological scores in the HQJZ group were lower than those in the model group (P<0.05). ConclusionHQJZ may inhibit white adipose tissue browning by promoting macrophage M1 polarization and suppressing M2 polarization, thereby delaying fat consumption in CC mice.

Background Cadmium (Cd) is a highly toxic heavy metal. Chronic low-dose cadmium exposure can lead to renal tubular dysfunction. However, the precise mechanisms by which cadmium induces renal tubular injury through disruption of intracellular metabolic networks remain incompletely understood. Objective To investigate the toxic effects of cadmium exposure on human renal tubular epithelial cells (HK-2) and to elucidate the associated metabolic regulatory network from the perspective of metabolic reprogramming. Methods An in vitro HK-2 cell injury model was established using 5 μmol·L−1 cadmium chloride (CdCl2). The expression of the renal injury marker kidney injury molecule-1 (KIM-1) was determined by Western blot (WB). Glycolytic capacity was evaluated by metabolic flux analysis. Mitochondrial reactive oxygen species (ROS) production was assessed with a fluorescent probe. Mitochondrial membrane potential (MMP) was evaluated after JC-1 staining. Intracellular adenosine triphosphate (ATP) levels were measured using an ATP assay kit. In addition, untargeted metabolomics analysis was conducted to characterize alterations in the intracellular metabolic fingerprint profile and to explore the metabolic pathway changes underlying cadmium-induced renal tubular epithelial cell injury. Results Cadmium exposure induced injury in HK-2 cells, as indicated by mitochondrial membrane depolarization, increased mitochondrial ROS levels, and decreased intracellular ATP levels. Metabolic flux analysis further revealed significant metabolic reprogramming, characterized by compensatory increases in basal glycolytic rate and maximal glycolytic capacity. Untargeted metabolomics showed depletion of the long-chain acylcarnitine pool and deficiency of key metabolic cofactors, suggesting impaired fatty acid oxidation and mitochondrial energy metabolism. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis indicated that the differential metabolites were mainly enriched in oxidative phosphorylation and glycerophospholipid metabolism. Correlation analysis showed that acylcarnitines were negatively correlated with nucleic acid metabolism-related metabolites, whereas ATP was positively correlated with lysophosphatidylcholine, suggesting that cadmium exposure-induced mitochondrial dysfunction may be accompanied by abnormal DNA metabolism and lipid peroxidation. Conclusion Cadmium exposure could induce impaired mitochondrial function, and promote glycolytic metabolic reprogramming in renal tubular epithelial cells. These findings provide new insights into the metabolic mechanisms underlying cadmium-induced nephrotoxicity and may help identify potential metabolic targets for intervention.

ObjectiveTo investigate the patterns of chronic disease comorbidity among permanent elderly residents in Xuhui District of Shanghai, and to analyze the impact of different comorbidity patterns on the elderly’s ability to perform activities of daily living. MethodsBased on data from the 2015 and 2021 Surveys on Health Status and Health Service Utilization among Permanent Residents in Xuhui District of Shanghai, the study included permanent residents who fully participated in both surveys, were aged 60 years or older at the 2015 survey, self-reported having a chronic disease, and reported no significant changes in their chronic disease status between the two surveys. A prospective cohort study design was adopted, using the 2015 data as the baseline and the 2021 survey data as follow-up data. Physical examinations and questionnaire surveys were conducted by the Shanghai Xuhui District Center for Disease Control and Prevention in the subdistricts and towns within the jurisdiction from April to July in both 2015 and 2021. Latent class analysis (LCA) was used to classify comorbidity patterns across 11 types of chronic diseases. The smaller the values of the Akaike information criterion (AIC), the Bayesian information criterion (BIC), and the sample-corrected Bayesian information criterion (aBIC), the better the model fits. The Barthel index (BI) and the Lawton and Brody Instrumental Activities of Daily Living Scale (LB-IADL) were used to assess the participants’ activities of daily living (ADL) and instrumental activities of daily living (IADL). Multiple linear regression and multivariate logistic regression models were used to analyze the association between different comorbidity patterns and ADL and IADL. ResultsA total of 1 608 study participants were enrolled. Among them, 671 (41.73%) self-reported having no chronic diseases. The prevalence of 11 types of chronic diseases was as follows: hypertension in 743 participants (46.21%), heart disease in 148 participants (9.20%), cerebrovascular disease in 37 participants (2.30%), diabetes or abnormal blood glucose in 310 participants (19.28%), other endocrine system diseases (non-diabetic) in 39 participants (2.43%), malignant tumors in 37 participants (2.30%), chronic lung disease in 16 participants (1.00%), gout in 8 participants (0.50%), musculoskeletal disorders in 34 participants (2.11%), gastric or digestive system diseases in 27 participants (1.68%), and dyslipidemia in 15 participants (0.93%). LCA was used to classify comorbidity patterns of chronic diseases among older adults into 1 to 9 latent category combinations. Model 5 (i.e., 5 latent categories) had the lowest BIC (7 112.69) and aBIC (6 909.38), with a relatively low AIC (6 768.20), indicating the best model fit; thus, five latent categories represented the optimal combination in this study. The five latent categories (and their respective proportions of study participants) were the healthy control group (41.73%), the hypertension group (31.28%), the diabetes-hypertension group (19.28%), the severe illness group (5.29%), and the other metabolic diseases group (2.43%). According to multiple linear regression analyses, compared with the healthy control group, the diabetes-hypertension group had significantly lower BI-20 scores (b=-0.952, 95%CI: -1.317‒ -0.587, P<0.001) and lower IADL scores (b=-0.744, 95%CI: -0.999‒ -0.489, P<0.001); the severe illness group (b=-0.644, 95%CI: -1.072‒ -0.217, P=0.003) and the hypertension group (b=-0.344, 95%CI: -0.562‒ -0.125, P=0.002) had lower IADL scores. According to multivariate logistic regression analyses, compared with the healthy control group, older adults in the diabetes-hypertension group had a higher risk of disability (OR=2.835, 95%CI: 1.392‒5.774), impaired ADL function (OR=2.470, 95%CI: 1.637‒3.726), and impaired IADL function (OR=1.739, 95%CI: 1.264‒2.392); older adults in the severe illness group had a higher risk of impaired ADL function (OR=2.206, 95%CI: 1.171‒4.155). ConclusionAmong the elderly participating in the Survey on Health Status and Health Service Utilization of Permanent Residents in Xuhui District of Shanghai, diabetes-hypertension is one of the key chronic disease comorbidity combinations and has adverse effects on both ADL and IADL. Community health management should prioritize the elderly with diabetes-hypertension comorbidity, and strengthen early screening and comprehensive interventions to slow the decline in ADL and IADL.
4.Analysis of parental expectations for the development and related factors of children with autism spectrum disorder
Chinese Journal of School Health 2026;47(9):1312-1316
Objective:
To assess parental expectations for the development of children with autism spectrum disorder (ASD) and identify factors associated with these expectations, so as to provide references for improving rehabilitation outcomes and long term development in children with ASD.
Methods:
From June 2024 to January 2026, a total of 877 children with ASD and their parents were recruited from 27 rehabilitation institutions in Hefei. The children had been diagnosed by chief physicians at tertiary level hospitals. Demographic characteristics and data on parental expectations were collected by the Parental Expectations Questionnaire. Differences in parental expectations between groups were assessed using the Mann-Whitney U- test and Kruskal-Wallis H-test, and associated factors were examined using quantile regression.
Results:
The mean item score for overall parental expectations among parents of children with ASD was (4.55±0.47), and scores for all dimensions were higher than those among parents of typically developing children ( t =11.11-31.14, all P <0.01). Child age, school enrollment, and maternal personality were associated with daily living expectation scores, learning and special talents and strengths expectation scores, and special talents and strengths expectation scores, respectively ( H =6.16-8.18, all P <0.05). Parents of preterm children had higher expectations for social interaction, physical and mental well being, and daily living than parents of non-preterm children ( Z =-2.56, -2.48, -2.39, all P <0.05). Multivariate quantile regression analysis showed that children’s age was associated with the expected level of self care ability; school enrollment status was associated with the expected level of learning and specialty strengths; maternal personality was associated with the expected levels of social competence, physical and mental health, self care ability, and specialty strengths; parental age was associated with the expected levels of physical and mental health and specialty strengths; and parental educational attainment was associated with the expected level of self care ability ( β =-0.36-0.41, all P <0.05).
Conclusion
Parents of children with ASD in Hefei generally have high expectations for their children s development across the domains of learning, daily living, social interaction, and physical and mental well being.

Objective:
To investigate the association between parenting styles and attention deficit hyperactivity disorder (ADHD) in preschool children,so as to provide a basis for family based interventions for ADHD in the population.
Methods:
Between August and December 2023, a random cluster sampling method was used to recruit 6 454 preschool children from 60 kindergartens in two counties/districts in Wuhu City, Anhui Province. The Swanson, Nolan, and Pelham Rating Scale, version IV was used to assess ADHD symptoms, and the Caregiver Parenting Style Questionnaire was applied to collect data on parenting styles. Multivariate Logistic regression was used to analyze the associations between parenting styles and ADHD subtypes.
Results:
Among the preschool children, 235 were screened positive for ADHD, with a positivity rate of 3.64%. Parenting style scores were as follows:indulgent parenting for 8.00 (7.00, 10.00), authoritative parenting for 38.00 (33.00, 41.00), permissive parenting for 14.00 (11.00, 17.00), authoritarian parenting for 17.00 (14.00, 20.00), and inconsistent parenting 10.00 (7.00, 12.00). Multivariate Logistic regression analysis showed that, after adjustment for confounding factors such as childrens sex, age, and family characteristics, preschool children with authoritarian parenting style were associated with higher odds of hyperactive ( OR = 1.13 ) and combined ADHD subtypes ( OR =1.11), while those with inconsistent parenting style were associated with higher odds of the inattentive subtype ( OR =1.09) (all P <0.01). Indulgent, democratic and permissive parenting styles showed no statistically significant associations with any ADHD subtype ( OR =1.02-1.07, 0.98-1.00, 1.01-1.03, all P >0.05).
Conclusions
Parenting styles are closely associated with the occurrence and subtypes of ADHD in preschool children. Authoritarian and inconsistent parenting styles are potential risk factors for ADHD in preschool children, and modifying adverse parenting styles may serve as an important strategy for family based interventions for ADHD in preschool children.

Objective:To evaluate the effects of chlorinated organophosphate flame retardants (Cl-OPFRs) via respiratory and digestive tract exposure on multiple organs in mice.Methods:A short-term repeated exposure model of tris(2-chloroethyl) phosphate (TCEP), tris(1-chloro-2-propyl) phosphate (TCIPP) and tris(1, 3-dichloro-2-propyl) phosphate (TDCIPP) in mice was established through intratracheal instillation and oral gavage administration. The exposure doses were 0.7, 1 and 2 mg·kg -1·day -1, respectively, with continuous administration for 14 days. The organs of the heart, liver, spleen, lung, kidney, stomach, large intestine, small intestine, bladder and testis were collected and weighed to calculate the organ coefficients. The pathological and histological changes were observed by hematoxylin-eosin staining to quantitatively assess the effects of the three Cl-OPFRs on the various organs by using the pathology score. Results:Analysis of organ coefficients in tracheal drip-treated mice showed that the organ coefficients in the testes of the TCEP, TCIPP and TDCIPP groups were lower than those in the control group ( PTCEP-testis=0.045, PTCIPP-testis=0.012 and PTDCIPP-testis<0.001). The organ coefficients were lower in the lungs and small intestines of the TCEP group ( PTCEP-lung=0.006, PTCEP-small intestine=0.042). The organ coefficients for the stomach and large intestine were higher in the TDCIPP group ( PTDCIPP-stomach=0.014, PTDCIPP-large intestine=0.049). Analyses of gavage-contaminated mice showed that the organ coefficients for liver, stomach and small intestine in the TCEP and TDCIPP groups were higher than those in the control group ( PTCEP-liver=0.007, PTCEP-stomach=0.003, PTCEP-small intestine<0.001, PTDCIPP-liver=0.001, PTDCIPP-stomach=0.004, and PTDCIPP-small intestine<0.001). Histopathological analyses of the organs of tracheal drip dyed mice showed significant pathological damage in the lung tissue of the TCIPP group, mainly in the form of thickening of the interstitium, infiltration of inflammatory cells and alveolar collapse. The results of the analysis of gavage poisoned mice showed that TCIPP exposure could lead to blurring of the red and white medullary boundaries of spleen tissues, destruction of white medullary structures, etc., and induce small intestinal cryptitis. TDCIPP induced significant pathological damage to the liver tissues of mice, which mainly included cytoplasmic washout, infiltration of inflammatory cells, acute inflammation, and other injurious effects. Significant pathological damage to the intestinal tissues of mice was also observed. Conclusions:This study demonstrates that the toxic effects of Cl-OPFRs are significantly associated with exposure routes and compound specificity. Respiratory exposure predominantly induces TCIPP-mediated pulmonary injury, while digestive exposure causes TDCIPP-driven hepatointestinal toxicity. These findings provide preliminary evidence for the toxicity screening of Cl-OPFRs.

The " no-accompany" service is an important measure to meet the patients′ needs for comprehensive, continuous, and high-quality diversified care and to enhance their medical experience. Starting in March 2024, the Second Affiliated Hospital of Zhejiang University School of Medicine launched a pilot " no-accompany" service in the breast surgery and dermatology wards. The hospital established a working team led by the nursing department and involving multiple administrative departments such as the medical affairs department, medical insurance office, and logistics management department. And the hospital has successfully advanced the implementation of the " no-accompany" ward program by establishing a multi-department collaborative management mechanism, standardizing the management of medical caregivers, developing a tiered fee scheme for the " no-accompany" service, and improving relevant service measures. The acceptance of the " no-accompany" service by patients increased from (3.93±0.83) in the second quarter of 2024 to (4.69±0.59) in the fourth quarter, and overall satisfaction rose from (4.18±0.73) to (4.50±0.54) (all P<0.001). The job competency of medical caregivers also improved significantly from (64.80±3.49) before starting work in March 2024 to (94.00±2.40) in the fourth quarter ( P<0.001). These findings provide a reference for the implementation of " no-accompany" services in public hospitals.
