ObjectiveTo establish an ultra-performance liquid fingerprint and multi-components determination method for Naomaili granules. To evaluate the quality of different batches by chemometrics, and the anti-neuroinflammatory effects of water extract and main components of Naomaili granules were tested in vitro. MethodsThe similarity and common peaks of 27 batches of Naomaili granules were evaluated by using Ultra performance liquid chromatography (UPLC) fingerprint detection. Ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) technology was used to determine the content of the index components in Naomaili granules and to evaluate the quality of different batches of Naomaili granules by chemometrics. LPS-induced BV-2 cell inflammation model was used to investigate the anti-neuroinflammatory effects of the water extract and main components of Naomaili granules. ResultsThe similarity of fingerprints of 27 batches of samples was > 0.90. A total of 32 common peaks were calibrated, and 23 of them were identified and assigned. In 27 batches of Naomaili granules, the mass fractions of 14 components that were stachydrine hydrochloride, leonurine hydrochloride, calycosin-7-O-glucoside, calycosin,tanshinoneⅠ, cryptotanshinone, tanshinoneⅡA, ginsenoside Rb1, notoginsenoside R1, ginsenoside Rg1, paeoniflorin, albiflorin, lactiflorin, and salvianolic acid B were found to be 2.902-3.498, 0.233-0.343, 0.111-0.301, 0.07-0.152, 0.136-0.228, 0.195-0.390, 0.324-0.482, 1.056-1.435, 0.271-0.397, 1.318-1.649, 3.038-4.059, 2.263-3.455, 0.152-0.232, 2.931-3.991 mg∙g-1, respectively. Multivariate statistical analysis showed that paeoniflorin, ginsenoside Rg1, ginsenoside Rb1 and staphylline hydrochloride were quality difference markers to control the stability of the preparation. The results of bioactive experiment showed that the water extract of Naomaili granules and the eight main components with high content in the prescription had a dose-dependent inhibitory effect on the release of NO in the cell supernatant. Among them, salvianolic acid B and ginsenoside Rb1 had strong anti-inflammatory activity, with IC50 values of (36.11±0.15) mg∙L-1 and (27.24±0.54) mg∙L-1, respectively. ConclusionThe quality evaluation method of Naomaili granules established in this study was accurate and reproducible. Four quality difference markers were screened out, and eight key pharmacodynamic substances of Naomaili granules against neuroinflammation were screened out by in vitro cell experiments.

OBJECTIVE To investigate the effects and mechanisms of Lycium ruthenicum Murr. in improving sleep. METHODS Network pharmacology was employed to identify the active components of L. ruthenicum and their associated disease targets, followed by enrichment analysis. A caffeine‑induced zebrafish model of sleep deprivation was established , and the zebrafish were treated with L. ruthenicum Murr. extract (LRME) at concentrations of 0.1, 0.2 and 0.4 mg/mL, respectively; 24 h later, behavioral changes of zebrafish and pathological alterations in brain neurons were subsequently observed. The levels of inflammatory factors [interleukin-6 (IL-6), IL-1β, IL-10, tumor necrosis factor-α (TNF-α)], oxidative stress markers [superoxide dismutase (SOD), malondialdehyde (MDA), glutathione peroxidase (GSH-Px), catalase (CAT)], and neurotransmitters [5- hydroxytryptamine (5-HT), γ-aminobutyric acid (GABA), glutamic acid (Glu), dopamine (DA), and norepinephrine (NE)] were measured. The protein expression levels of protein kinase B1 (AKT1), phosphorylated AKT1 (p-AKT1), epidermal growth factor receptor (EGFR), B-cell lymphoma 2 (Bcl-2), sarcoma proto-oncogene,non-receptor tyrosine kinase (SRC), and heat shock protein 90α family class A member 1 (HSP90AA1) in the zebrafish were also determined. RESULTS A total of 12 active components and 176 intersecting disease targets were identified through network pharmacology analysis. Among these, apigenin, naringenin and others were recognized as core active compounds, while AKT1, EGFR and others served as key targets; EGFR tyrosine kinase inhibitor resistance signaling pathway was identified as the critical pathway. The sleep improvement rates in zebrafish of LRME low-, medium-, and high-dose groups were 54.60%, 69.03% and 77.97%, 开发。E-mail:hjp_yft@163.com respectively, while the inhibition ratios of locomotor distance were 0.57, 0.83 and 0.95, respectively. Compared with the model group, the number of resting counts, resting time and resting distance were significantly increased/extended in LRME medium- and high-dose groups (P<0.05). Neuronal damage in the brain was alleviated. Additionally, the levels of IL-6, IL-1β, TNF-α, MDA, Glu, DA and NE, as well as the protein expression levels of AKT1, p-AKT1, EGFR, SRC and HSP90AA1, were markedly reduced (P<0.05), while the levels of IL-10, SOD, GSH-Px, CAT, 5-HT and GABA, as well as Bcl-2 protein expression, were significantly elevated (P<0.05). CONCLUSIONS L. ruthenicum Murr. demonstrates sleep-improving effects, and its specific mechanism may be related to the regulation of inflammatory responses, oxidative stress, neurotransmitter balance, and the EGFR tyrosine kinase inhibitor resistance signaling pathway.

Objective:
To assess the effect of 12-year-old children s pit and fissure sealants on the health of first permanent molars, so as to provide evidence for optimizing caries prevention strategies among children.
Methods:
In March 2025, a cluster random sampling method was used to conduct oral examinations on 965 students aged 12 from Chengdu s 2021 Comprehensive Intervention Program for Pediatric Oral Diseases. Data from the Comprehensive Intervention System for Children s Oral Diseases were referenced. Participants were divided into a sealed group ( n =755) and an unsealed group ( n =210) based on whether they had received sealants on their first permanent molars. Chi square test or analysis of variance were used to compare indicators such as caries incidence, new caries detection rate, and new caries mean (DMFT increment) between the two groups
Results:
The sealed group showed significantly lower caries incidence, new caries detection rate, and new caries mean (33.38%, 17.65%, 0.59±1.00) compared to the unsealed group (43.81%, 24.70%, 0.87±1.22)( χ 2/F =7.79, 18.26, 9.55, all P <0.05). However, no significant difference was found in the filled teeth ratio between the two groups (20.38% , 20.16%; χ 2=0.01, P =0.94). In girls, the sealed group exhibited significantly lower caries incidence, new caries detection rate, and new caries mean (36.78%, 20.99%, 0.69± 1.10 ) than the unsealed group (57.55%, 33.52%, 1.15±1.29) ( χ 2/F =14.42, 23.76, 10.92, all P <0.05), whereas no significant differences were observed between boys in the sealed (30.47%, 14.85%, 0.50±0.89) and unsealed groups (29.81%, 16.18%, 0.59± 1.08) ( χ 2/F =0.02, 0.41, 0.74, all P >0.05). Boys had significantly lower new caries detection rates and new caries means than girls in both groups ( χ 2/F =16.20, 6.94; 29.93, 11.84, all P <0.05). In urban areas, the sealed group had lower new caries detection rates and new caries means (19.37%, 0.68±1.04) than the unsealed group (24.66%, 0.90±1.20) ( χ 2/F =6.86, 3.94, both P <0.05). In suburban areas, all indicators for the sealed group (24.71%, 13.77%, 0.42±0.87) were significantly lower than those for the unsealed group (38.81%, 24.77%, 0.82±1.28) ( χ 2/F =5.28, 15.36, 6.00, all P <0.05). Indicators from specialized dental institutions (11.25%, 4.81%, 0.16±0.56) were significantly lower than those from county level or above general hospitals (33.33%, 19.11%, 0.38±1.00) and primary healthcare institutions (37.59%, 19.24%, 0.67±1.05) ( χ 2/F =20.99, 34.31, 21.08 , all P <0.01).
Conclusions
The 12-year-old children s pit and fissure sealants effectively reduce the caries incidence in first permanent molars, particularly showing significant effectiveness in girls and suburban children. Intervention strategies should be optimized according to gender.

ObjectiveTo investigate the potential mechanism of Danggui Shaoyaosan (DSS) in ameliorating renal injury in db/db mice. MethodsThirty 8-week-old specific pathogen-free (SPF)-grade male db/db mice and six db/m mice were acclimated for one week. Urinary microalbumin and blood glucose levels were measured weekly in both db/db and db/m mice. Successful modeling was determined by significantly higher microalbuminuria in db/db mice compared to db/m mice and a fasting blood glucose ≥16.7 mmol·L-1. The 30 db/db mice were randomly divided into five groups: the model group, the irbesartan (IBN) group, and three DSS dose groups (low-, medium-, and high-dose DSS groups, administered at 16.77, 33.54, 67.08 g·kg-1·d-1, respectively). Additionally, the six db/m mice served as the normal control group. The IBN group received irbesartan at 0.025 g·kg-1·d-1 by gavage, while the three DSS groups received DSS at 16.77, 33.54, and 67.08 g·kg-1·d-1 by gavage, respectively. The normal and model groups were administered with an equivalent volume of normal saline by gavage. All interventions lasted for 8 consecutive weeks. After intervention, serum creatinine (SCr), blood urea nitrogen (BUN), urinary total protein (UTP), triglyceride (TG), and low-density lipoprotein cholesterol (LDL-C) were measured to evaluate the therapeutic efficacy of the treatments. Renal histopathological changes were observed with hematoxylin-eosin (HE) staining. Western blot was used to detect the protein expression of silencing information regulator 1 (SIRT1), hypoxia-inducible factor-1α (HIF-1α), very low-density lipoprotein receptor (VLDLr), and cluster of differentiation 31 (CD31). Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was used to detect the mRNA levels of HIF-1α and VLDLr. Immunohistochemistry was used to observe the expression and distribution of HIF-1α and Caspase-3. ResultsCompared to the normal group, the model group showed significantly increased SCr, BUN, UTP, TG, and LDL-C. HE staining revealed glomerulosclerosis, mesangial matrix hyperplasia, capillary loop distortion and thickening, with extensive inflammatory cell infiltration. Protein expression of SIRT1 and CD31 significantly decreased (P<0.05), while HIF-1α and VLDLr protein and mRNA levels increased (P<0.05). Immunohistochemistry showed increased expression of HIF-1α and Caspase-3 (P<0.05), indicating hypoxia and apoptosis in renal cells. In all treatment groups, SCr, BUN, TG, and LDL-C were significantly reduced compared to the model group (P<0.05), and UTP was significantly improved in the medium-dose DSS group (P<0.05). Renal tissue structure and morphology were improved, inflammatory cells were reduced, and no vascular hyaline degeneration was observed. SIRT1 and CD31 protein expression was elevated to varying degrees compared to the model group (P<0.05), while HIF-1α and VLDLr protein and mRNA levels decreased (P<0.05). Immunohistochemistry showed reduced expression of HIF-1α and Caspase-3 in all treatment groups (P<0.05), with the most significant improvement observed in the IBN group and medium-dose DSS group (P<0.05). ConclusionDSS can effectively ameliorate glomerulosclerosis and lipid deposition in db/db mice, and its mechanism may involve the SIRT1/HIF-1α/VLDLr signaling pathway.

ObjectiveTo investigate the therapeutic efficacy of Danggui Shaoyaosan (DSS) on renal injury in db/db mice and its impact on endoplasmic reticulum stress (ERS) in renal tissues. MethodsThirty 8-week-old male db/db mice and six db/m mice were acclimated for one week, after which urinary microalbumin and blood glucose levels were monitored to establish a diabetic kidney disease (DKD) model. The model mice were randomly divided into a model group, an irbesartan group, and three DSS treatment groups with different doses (16.77, 33.54, and 67.08 g·kg-1·d-1). A normal group was set as control. Each group was intragastrically administered with the corresponding drugs or saline for 8 weeks. After the intervention, general conditions were observed. Serum cystatin C (Cys-C), 24-hour urinary total protein (24 h-UTP), 24-hour urinary microalbumin (24 h-UMA), urinary creatinine (Ucr), and urea nitrogen (UUN) were measured. Transmission electron microscopy (TEM) was used to observe glomerular basement membrane (GBM) and ultrastructural changes of the endoplasmic reticulum (ER) in glomerular endothelial cells. Western blot, real-time fluorescence quantitative polymerase chain reaction (Real-time PCR), and immunohistochemistry were used to analyze renal tissue structure and the expression of GRP78, CHOP, and related markers. ResultsCompared with the normal group, the mice in the model group showed curled posture, sluggish response, poor fur condition, increased levels of Cys-C, 24 h-UTP, 24 h-UMA, and UUN (P<0.05), while Ucr decreased (P<0.05). The GBM was significantly thickened, with podocyte and foot process fusion. The protein expressions of GRP78, CHOP, and ATF6 were significantly upregulated (P<0.05), the mRNA levels of GRP78 and CHOP increased (P<0.05), and immunohistochemistry showed an enhanced GRP78 signal (P<0.05). After treatment, the mice exhibited improved behavior, normalized GBM and podocyte structure, improved ER morphology and markedly better biochemical indicators. Western blot, Real-time PCR, and immunohistochemistry indicated that the ERS-related markers were downregulated in the DSS treatment groups (P<0.05), suggesting alleviated ERS and improved renal function. ConclusionDSS can effectively ameliorate renal pathological damage in db/db mice, possibly by regulating ERS in glomerular endothelial cells, although the underlying signaling mechanisms require further investigation.

As a distinctive resource of Chinese civilization, traditional Chinese medicine (TCM) technology transfer faces significant opportunities under the background of digital and intelligent transformation, while also being constrained by unique challenges such as the complexity of its theoretical system, lengthy industrial chains, and multidimensional policy restrictions, resulting in a "high-value-high-threshold" paradox. At present, TCM technology transfer is deeply trapped in a "threefold reluctance" dilemma, i.e., unwillingness to transfer, inability to transfer, and lack of capacity to transfer. Specifically, the disconnection between scientific research evaluation systems and market demand leads to low conversion rates of research achievements, unclear ownership and compliance risks suppress innovation incentives, and the absence of professional services intensifies supply-demand mismatches. This article systematically analyzes the specific characteristics of TCM technology transfer and proposes a breakthrough pathway centered on full-chain digital and intelligent transformation. By integrating technologies such as intelligent sorting systems, blockchain-based traceability, and AI diagnostic models, the TCM ecosystem spanning "cultivation-production-service" can be reconstructed. In terms of standardization, promoting the progression from "experience-based data conversion" to "data standardization" and further to "intelligent standardization" is advocated to resolve quality control challenges. For example, a "three-no-one-full" certification system can strengthen quality trust. Policy coordination should focus on optimizing mechanisms for the transformation of scientific and technological achievements, while exploring intellectual property securitization and risk-sharing models to stimulate research momentum. In terms of internationalization, reliance on the Belt and Road Initiative platform to promote the export of geo-authentic medicinal material brands and standards is recommended to build a dual-driven model of "technology plus culture". Looking ahead, through the construction of national-level databases, the cultivation of interdisciplinary talent, and the mutual recognition of international standards, a new paradigm of "scientific intelligent manufacturing" can be formed, providing systematic solutions for the modernization of TCM and global health governance.

ObjectiveTo explore the relationship between negative life events and depression severity in adolescent patients with depressive disorder, as well as the chain mediating role of insomnia symptoms and quality of life. Methods374 outpatient patients and hospitalized patients with adolescent depressive disorders were enrolled. The Adolescent Life Event Scale (ASLEC), the Insomnia Severity Index (ISI), the World Health Organization Quality of Life Questionnaire Short Form (WHOQOL-BREF), and the Center for Epidemiology Depression Scale (CES-D) were used to evaluate the negative life event situation, insomnia symptoms, quality of life level and depression severity of the subjects, respectively. In addition, the PROCESS 4.0 macroprogram was used to analyze the chain mediating effect of insomnia symptoms and quality of life between negative life events and depression severity in patients with adolescent depressive disorder. ResultsThe results of correlation analysis showed that there was a significant correlation between negative life events and insomnia symptoms, quality of life, and depression severity (all P<0.05). In addition, the results of chain mediation showed that negative life events had a significant direct effect on depression severity, with an effect size of 0.12 (P<0.001). Insomnia symptoms and quality of life played a mediating role in the relationship between negative life events and depression severity in patients with adolescent depressive disorders, with indirect effect sizes of 0.062 (95%CI: 0.040-0.087) and 0.091 (95%CI: 0.059-0.123), respectively. It could also play a chain mediation role, and the effect size was 0.039 (95%CI: 0.024-0.057). ConclusionNegative life events experienced by patients with adolescent depressive disorder not only directly affect the severity of depressive symptoms, but may also indirectly exacerbate depression through insomnia symptoms and quality of life.

Objective To develop an automated system for the determination of gross α and gross β activity concentrations in water, and to support the rapid and automated monitoring of environmental water bodies. Methods Based on the thick source method, microwave evaporation-ashing was used to replace conventional electric hotplate heating. A grinder and a sample-spreading device were designed and operated via a robotic arm, achieving fully automated pretreatment, sample preparation, and measurement. Results Spike recovery tests demonstrated that the recovery rates were 95.7%-102.5% for gross α and 97.2%-108.1% for gross β. The relative standard deviations were 4.1%-7.8% for gross α and 5.9%-7.7% for gross β. Compared with manual laboratory methods, the average relative errors were 2.17%-6.25% for gross α and 4.17%-6.90% for gross β. The sample preparation time was reduced from an average of 72 hours to less than 5 hours, representing an efficiency improvement of over 90%. Conclusion The developed system enables rapid, accurate, and fully automated monitoring of gross α/β radioactivity, making it suitable for online monitoring of environmental water bodies. It can provide timely data on the radiological indicators of water bodies for environmental protection and water resource management authorities.
