ObjectiveTo explore the improving effect of Huangqi Chifengtang（HCT） on atherosclerosis（AS）， and elucidate its mechanism in relation to adenosine monophosphate-activated protein kinase（AMPK）/peroxisome proliferator-activated receptor α（PPARα） signaling pathway and nucleotide-binding oligomerization domain（NOD）-like receptor thermal protein domain associated protein 3（NLRP3） inflammasome. MethodsEight C57BL/6J mice were set as the normal group， and 32 ApoE^-/- mice were randomly divided into the model group， the positive drug group（atorvastatin， 5 mg·kg^-1·d^-1）， HCT low- and high-dose groups（1.95， 3.90 g·kg^-1·d^-1）. ApoE^-/- mice were fed with high-fat and high-cholesterol feed to establish an AS mouse model. After modeling， they were orally administered corresponding dose of drugs for 28 days， while the normal and model groups received an equal volume of physiological saline via oral gavage. Hematoxylin-eosin（HE） staining was used to observe the pathological status of the aorta and liver in mice， Biochemical testing and enzyme-linked immunosorbent assay（ELISA） were used to detect the levels of total cholesterol（TC）， triglycerides（TG）， low-density lipoprotein cholesterol（LDL-C）， alanine aminotransferase（ALT）， aspartate aminotransferase（AST）， C-reactive protein（CRP）， interleukin（IL）-1β， IL-18 in the serum， as well as superoxide dismutase（SOD）， malondialdehyde（MDA）， and reduced glutathione（GSH） in the liver. Real-time fluorescence quantitative polymerase chain reaction（Real-time PCR） was used to measure the mRNA expression levels of NLRP3， apoptosis-associated speck-like protein（ASC）， cysteinyl aspartate specific proteinase-1（Caspase-1）， Toll-like receptor 4（TLR4） in the aorta， and fatty acid synthase（FAS）， stearoyl-CoA desaturase 1（SCD1）， PPARα， and carnitine palmitoyltransferase 1A（CPT1A） in the liver. Immunohistochemistry was used to determine the protein expressions of NLRP3， Caspase-1， and ASC in the aorta， and Western blot was used to measure the protein expressions of AMPK， p-AMPK， sterol regulatory element binding protein-1c（SREBP-1c）， CPT1A， and FAS in the liver. ResultsCompared with the normal group， the model group showed a significant increase in lipid plaque deposition in the aorta and lipid accumulation in the liver， the levels of TC， TG， LDL-C， AST， ALT， IL-1β， IL-18 and CRP in the serum were significantly increased（P<0.01）， and the mRNA and protein expressions of aortic TLR4， NLRP3， Caspase-1 and ASC were significantly upregulated（P<0.01）. The levels of SOD and GSH in the liver were significantly reduced， while the level of MDA was significantly increased（P<0.01）. The mRNA expressions of FAS and SCD1 in the liver were significantly downregulated， while the mRNA expressions of PPARα and CPT1A were significantly upregulated. The protein expressions of p-AMPK/AMPK and CPT1A in the liver were significantly reduced， while the expressions of SREBP-1c and FAS proteins were significantly increased（P<0.01）. Compared with the model group， the low- and high-dose HCT groups showed significant improvements in aortic plaques and hepatic lipid deposition. The levels of TC， LDL-C， AST， IL-1β and IL-18 in the serum of the low-dose HCT group， as well as TC， TG， LDL-C， AST， ALT， IL-1β， IL-18 and CRP in the serum of the high-dose HCT group， were significantly reduced（P<0.01）. The mRNA expressions of TLR4， NLRP3 and Caspase-1 in the aorta of the low-dose HCT group， as well as TLR4， NLRP3， Caspase-1 and ASC in the aorta of the high-dose HCT group， were significantly downregulated（P<0.01）. The protein expressions of Caspase-1 and ASC in the aorta of the low-dose HCT group， as well as NLRP3， Caspase-1 and ASC in the high-dose HCT group， were significantly downregulated（P<0.01）. The levels of SOD and GSH in the liver of the low- and high-dose HCT groups were significantly increased， while the level of MDA in the high-dose HCT group was significantly decreased（P<0.05， P<0.01）. In the HCT-treated group， the mRNA expressions of FAS and SCD1 in the liver were significantly upregulated， while the mRNA expressions of PPARα and CPT1A were significantly downregulated， the protein expressions of p-AMPK/AMPK and CPT1A in the liver were significantly increased， while the protein expressions of SREBP-1c and FAS were significantly decreased（P<0.05， P<0.01）. ConclusionHCT can improve lipid metabolism by activating the AMPK/PPARα pathway and inhibit NLRP3 inflammasome-mediated inflammatory responses， thereby reducing hepatic lipid deposition and AS plaque formation.

To explore the advantages of traditional Chinese medicine （TCM） and integrative TCM-Western medicine approaches in the treatment of diabetic microvascular complications （DMC）， refine key pathophysiological insights and treatment principles， and promote academic innovation and strategic research planning in the prevention and treatment of DMC. The 38th session of the Expert Salon on Diseases Responding Specifically to Traditional Chinese Medicine， hosted by the China Association of Chinese Medicine， was held in Beijing， 2024. Experts in TCM， Western medicine， and interdisciplinary fields convened to conduct a systematic discussion on the pathogenesis， diagnostic and treatment challenges， and mechanism research related to DMC， ultimately forming a consensus on key directions. Four major research recommendations were proposed. The first is addressing clinical bottlenecks in the prevention and control of DMC by optimizing TCM-based evidence evaluation systems. The second is refining TCM core pathogenesis across DMC stages and establishing corresponding "disease-pattern-time" framework. The third is innovating mechanism research strategies to facilitate a shift from holistic regulation to targeted intervention in TCM. The fourth is advancing interdisciplinary collaboration to enhance the role of TCM in new drug development， research prioritization， and guideline formulation. TCM and integrative approaches offer distinct advantages in managing DMC. With a focus on the diseases responding specifically to TCM， strengthening evidence-based support and mechanism interpretation and promoting the integration of clinical care and research innovation will provide strong momentum for the modernization of TCM and the advancement of national health strategies.

Objective: To explore the associations between caregivers nutrition literacy and pediatric nonalcoholic fatty liver disease (NAFLD), so as to provide scientific evidence for the key contents of family intervention measures. Methods: In September 2022, a study involving 1 609 thirdgrade students and their caregivers from six schools in Yinzhou, Haishu, and Zhenhai Districts of Ningbo City, Zhejiang Province, was conducted. Venous blood samples were collected to measure lipid profiles and investigate the prevalence of nonalcoholic fatty liver disease (NAFLD) among the children. Family Food Environment Questionnaire was used to assess the nutrition literacy levels of the caregivers. Generalized linear regression analysis was employed to explore the correlation between caregivers nutrition literacy levels and the prevalence of NAFLD in children. Results: Among the surveyed students, 191 were in the NAFLD group, whereas 1 418 were in the nonNAFLD group. The median nutrition literacy score of caregivers in the NAFLD group and nonNAFLD group all were 11.00 (9.00,12.00), which was not significantly different (Z=-0.40, P=0.71). The generalized linear regression results revealed that the level of nutrition literacy of caregivers had no significant effect on childrens Triglyceride-glucose (TyG) index and Triglyceride-glucose-Waisttoheight ratio (TyG-WHtR) [β(95%CI) were 0.001(-0.005-0.006) and 0.000(-0.014-0.014), P>0.05]. Conclusions The nutrition literacy level of caregivers has no significant correlation with the direct incidence of NAFLD in children. As for family intervention measures, it is necessary not only to improve the nutrition literacy level of caregivers but also to effectively apply nutritional knowledge in practice to optimize health management.

Objective: To investigate the current status of refractive errors and insufficient hyperopia reserve in preschool children aged 3-6 years in Hefei and to analyze influencing factors, so as to provide a scientific basis for formulating targeted myopia prevention policies and comprehensive interventions. Methods: In May 2022, a stratified cluster random sampling method was used to select 897 preschool children from 8 kindergartens across four districts (Baohe, Yaohai, Shushan, and Economic and Technological Development Zone) in Hefei, and Children’s Visual Health related Behavior Assessment Scale was used to collect personal information and environmental factors. Pre and post cycloplegic refraction tests were conducted to assess insufficient hyperopic reserve and refractive development levels. Group comparisons were conducted using 2 test, t-test or analysis of variance. Multivariate regression analysis was performed to identify key factors influencing hyperopic reserve, axial length and spherical equivalent in preschool children. Results: The detection rates of refractive errors among preschool children were 6.8% for hyperopia, 1.6% for myopia, and 11.1% for astigmatism. Notably, the prevalence of myopia was significantly higher in boys (2.3%) than in girls (0.7%) ( χ 2=3.88, P <0.05). Additionally, 8.8% of the children exhibited insufficient hyperopic reserve. The results of multiple regression analysis showed that preschool children with high myopia in the father, high myopia in the mother, longer daily duration of near work, and longer daily electronic product use time had increased risks of axial growth ( β =0.12, 0.09, 0.15, 0.11), SE reduction ( β =-0.10, -0.07, -0.18, -0.13), and insufficient hyperopic reserve ( OR=1.87, 2.22, 1.40, 1.28) (P <0.05). While, preschool children with longer sleep time and daily outdoor activity duration had lower risks of axial growth ( β =-0.11, -0.10 ), SE reduction ( β =0.39, 0.51), and insufficient hyperopia reserve ( OR =0.54, 0.51) in preschool children ( P <0.05). Conclusions The rates of refractive errors and insufficient hyperopia reserve in preschool children in Hefei are relatively low, which are influenced by many factors. Parents, kindergartens and relevant departments should implement early vision monitoring and intervention for preschool children, and cultivate their scientific eye use habits.

Objective:To explore the effect of multidisciplinary comprehensive nursing under the Green Intensive Nursing Model on the clinical outcomes of patients with post-traumatic epilepsy (PTE) .Methods:A convenience sampling method was used to select 120 patients with PTE admitted to the Department of Neurosurgery, Zhumadian Central Hospital, from January 2022 to May 2024. Patients were randomly divided into an intervention group ( n=60) and a control group ( n=60) using a computer-generated random number table. The control group received routine neurosurgical nursing, while the intervention group received multidisciplinary comprehensive nursing under the Green Intensive Nursing Model in addition to routine nursing. The Quality of Life in Epilepsy Inventory-31 (QOLIE-31), Hospital Anxiety and Depression Scale (HADS), Barthel Index, and Montreal Cognitive Assessment (MoCA) were used for evaluation. Seizure frequency, quality of life, anxiety and depression, activities of daily living, and cognitive-behavioral function were compared between the two groups after intervention. Results:At the 3-month follow-up, the intervention group had fewer seizures than the control group, and the difference was statistically significant ( P<0.05). After the intervention, the QOLIE-31 scores, Barthel Index, and MoCA scores of the intervention group were higher than those of the control group, while the HADS scores were lower, the differences were statistically significant ( P<0.05) . Conclusions:Multidisciplinary comprehensive nursing under the Green Intensive Nursing Model can reduce seizure frequency in PTE patients, improve their quality of life, decrease anxiety and depression, enhance daily living ability, and improve cognitive-behavioral function.

OBJECTIVE: To explore the clinical characteristics and genetic etiology of a child with Neurofibromatosis-Noonan syndrome (NFNS). METHODS: A child with NFNS who was treated at the Department of Endocrinology of Hangzhou Children's Hospital in January 2024 was selected as the study subject. Clinical data of the child was collected by retrospective analysis. Peripheral venous blood samples (2 mL each) were collected from the child and his parents. Genomic DNA was extracted, and trio-whole exome sequencing (Trio-WES) of the family was carried out. Sanger sequencing was used to perform family verification on the candidate variants. The identified variants were classified for pathogenicity according to the Standards and Guidelines for the Interpretation of Sequence Variants established by the American College of Medical Genetics and Genomics (ACMG) (hereafter referred to as the "ACMG guidelines"). This study has been approved by the Medical Ethics Committee of Hangzhou Children's Hospital (Ethics No. 2021-06). RESULTS: The child was a 7-year and 4-month-old male. He has short stature, numerous café-au-lait spots on the neck and trunk, and special facial features such as a full forehead, wide interpupillary distance, a low nasal bridge, and low-set ears. The results of Trio-WES showed that the he had harbored the NF1 gene c.3773G>T (p.W1258L) mutation, which was verified by Sanger sequencing to be de novo in origin. The NF1 gene was associated with NFNS, which has an autosomal dominant inheritance. According to the ACMG guidelines, this variant was judged to be a likely pathogenic variant (PS2+PM2+PP3+PP2). No pathogenic variant in genes associated with Noonan syndrome, such as PTPN11, SOS1, RAF1, RIT1, and KRAS, was found. CONCLUSION The child with NFNS has clinical features such as short stature, special facial features, and café-au-lait spots. The c.3773G>T (p.W1258L) variation in the NF1 gene may be the genetic etiology of the NFNS child in this study. The results of this study has enriched the variation spectrum of the NF1 gene.
