The 20th National Congress of the Communist Party of China emphasized the expansion of international scientific and technological exchanges and cooperation. Against this backdrop, the radiological health research institutions bear important responsibilities in the field of international radiological health. As a key institution in the industry, the National Institute for Radiological Protection (NIRP), Chinese Center for Disease Control and Prevention shoulders the important mission of promoting international exchanges in radiation health in China. A case study was conducted on the NIRP using data of official overseas visits from 2010 to 2024. The SWOT analysis was used to comprehensively and systematically examine the strengths, weaknesses, opportunities, and challenges of NIRP in international cooperation and exchanges. To effectively enhance the depth and scope of international exchanges, this article proposes a series of innovative optimization strategies such as establishing dedicated personnel positions to ensure efficient handling of affairs, implementing stringent approval procedures to guarantee the rationality and compliance of overseas visits, strengthening pre-departure training to improve the professionalism of outbound personnel, conducting follow-up evaluations to continuously refine management practices, and centralizing the management of official passports to ensure their secure use. This article aims to provide practical optimization strategies for the management of official overseas visits for NIRP and other similar institutions, promote international exchanges and cooperation in the field of radiation health, and help China play a more important role in the global radiation health field.

Sustained inflammatory responses are closely related to various severe diseases, and inhibiting the excessive activation of inflammasomes and pyroptosis has significant implications for clinical treatment. Natural products have garnered considerable concern for the treatment of inflammation. Huanglian-Wumei decoction (HLWMD) is a classic prescription used for treating inflammatory diseases, but the necessity of their combination and the exact underlying anti-inflammatory mechanism have not yet been elucidated. Inspired by the supramolecular self-assembly strategy and natural drug compatibility theory, we successfully obtained berberine (BBR)-chlorogenic acid (CGA) supramolecular (BCS), which is an herbal pair from HLWMD. Using a series of characterization methods, we confirmed the self-assembly mechanism of BCS. BBR and CGA were self-assembled and stacked into amphiphilic spherical supramolecules in a 2:1 molar ratio, driven by electrostatic interactions, hydrophobic interactions, and π-π stacking; the hydrophilic fragments of CGA were outside, and the hydrophobic fragments of BBR were inside. This stacking pattern significantly improved the anti-inflammatory performance of BCS compared with that of single free molecules. Compared with free molecules, BCS significantly attenuated the release of multiple inflammatory mediators and lipopolysaccharide (LPS)-induced pyroptosis. Its anti-inflammatory mechanism is closely related to the inhibition of intracellular nuclear factor-kappaB (NF-κB) p65 phosphorylation and the noncanonical pyroptosis signalling pathway mediated by caspase-11.

OBJECTIVE To study the fingerprint of Denghong buyang huanwu granules (DBHG), screen the quality markers, and establish the method for content determination of active ingredients. METHODS HPLC method was adopted. The fingerprints of 10 batches of DBHG (S1-S10) were established by using the Similarity Evaluation System for Chromatographic Fingerprint of Traditional Chinese Medicine (2012 edition), and similarity evaluation was also performed. Traditional Chinese medicine pieces attribution analysis, cluster analysis (CA), principal component analysis (PCA) and orthogonal partial least squares discriminant analysis (OPLS-DA) were conducted for common peaks, and quality biomarkers were screened based on variable importance projection (VIP) values>1. The contents of 10 batches of samples were determined by the same HPLC method, such as salidroside, tyrosol, calycosin-7-O-beta-D-glucoside, scutellarin and calycosin. RESULTS A total of 25 common peaks were obtained in the fingerprints for 10 batches of samples and 6 common peaks were identified, i.e. salidroside, tyrosol, paeoniflorin, calycosin-7-O-beta-D-glucoside, scutellarin, calycosin. Their similarities were greater than 0.9, and 10 common peaks of them were unique components of Erigeron breviscapus. DBHG could be clustered into 2 categories by using CA and PCA; S4-S5, and S7 could be clustered into one category and other samples could be clustered into one category. The corresponding components of peaks 16 (scutellarin), 12, 15 (calycosin-7-O-beta-D-glucoside), 13 (paeoniflorin), and 14 were quality markers. The average contents of salidroside, tyrosol, calycosin-7-O-beta-D-glucoside, scutellarin and calycosin were 1.64, 0.45, 0.31, 0.73, 0.15 mg/g in 10 batches of samples. CONCLUSIONS HPLC fingerprint for DBHG and a method for determining the contents of five active ingredients including salidroside are successfully established. Five quality markers have been screened. It can be used for the quality control of the preparation.

Graduate education is critical for cultivation of high-level talents and promotion of technological innovation. Strengthening the management of graduate education is of great practical significance for ensuring and improving the quality of graduate education. The expansion of graduate education brings challenges to educational resources and management models, requiring research institutions to ensure educational quality and adapt to social needs. Based on the particularity of research institutes, this article takes the practice of radiation health graduate education as an example to explore the graduate student management elements of form teachers in research institutes. Our research provides a reference for improving the management level of graduate students in research institutes. Graduate form teachers are organizers, implementers, and mentors of graduate ideological education, academic culture, daily management, employment and entrepreneurship, and mental health education. They play an important role as a bridge and link in graduate education and cultivation. Faced with the challenges of graduate education in the new era, form teachers should continuously explore work methods that adapt to the needs of the era. They should also focus on reinforcing ideological and political theories, improving professional skills, establishing and improving management systems, and leveraging the role of student cadres to ensure the high-quality development of graduate education in research institutes.

Objective:To investigate the correlation between triglyceride-glucose (TyG) index on admission and unfavorable outcomes of patients with moderate-to-severe traumatic brain injury (msTBI) at 6 months postinjury.Methods:A retrospective cohort study was conducted to analyze the clinical data of 277 patients with msTBI admitted to Affiliated Jiangyin Hospital of Nantong University from January 2019 to December 2022, including 208 males and 69 females, aged 18-88 years [(57.0±15.1)years]. Glasgow Coma Scale (GCS) scores on admission were 3-8 points in 168 patients and 9-12 points in 109. According to the Glasgow Outcome Scale-Extended (GOSE) assessment at 6 months after injury, there were 121 patients with unfavorable outcomes (GOSE≤4 points) and 156 with favorable outcomes (GOSE≥5 points). The following indicators of the patients were recorded, including gender, age, history of diabetes, cause of injury, admission GCS, GCS motor score (GCSM), pupillary light reflex, worst Marshall CT classification within the first 24 hours after admission, admission TyG index, Mean Amplitude of Glycemic Excursions (MAGE) within 24 hours after admission, GCSM decline≥2 points within 72 hours after admission, craniotomy or not after admission, and prognosis, etc. TyG index served as the exposure variable focused in this study, which was calculated with fasting triglycerides and fasting blood glucose within 24 hours after admission. The 6-month prognosis of the patients was designated as the outcome variable of the study. After the patients were divided into different groups according to the three quantiles of the TyG index and unfavorable or favorable outcomes, the univariate analysis was conducted on watch variables, and variables with statistically significant differences were included in directed acyclic graphs (DAGs) for further identification of confounding variables. Factors which were found with no statistical significance in the univariate analysis but might affect insulin resistance after injury according to the authors′ previous researches were also included in the DAGs analysis. Three Logistic regression models were designed (Model 1 without correction, Model 2 with core variables of International Mission for Prognosis and Analysis of Clinical Trials in Traumatic Brain Injury (IMPACT) corrected, and Model 3 with confounding variables screened by DAGs corrected) to analyze whether the TyG index was an independent risk factor for the prognosis of msTBI patients. The optimal Logistic regression model was selected and then restricted cubic spline (RCS) was employed to investigate the relationship between the TyG index and the unfavorable outcomes.Results:The univariate analysis suggested that there were significant differences in gender, history of diabetes, MAGE, GCSM decline, and prognosis among the three quantiles of the TyG index ( P<0.05 or 0.01). Significant differences in age, history of diabetes, GCSM, pupillary light reflex, Marshall CT classification, TyG index, MAGE and GCSM decline were observed between unfavorable and favorable outcome groups ( P<0.05 or 0.01). The results of Logistic regression analysis that identified the confounding variables that influenced the correlation between the TyG index and unfavorable prognosis with DAGs suggested that a high TyG index level was significantly correlated with unfavorable outcomes in msTBI patients. Moreover, Model 3 that was corrected with confounding variables screened by DAGs had an optimal goodness-of-fit and adaptability. Model 3-based further RCS analysis indicated that the risk of unfavorable outcomes following msTBI may increase approximately linearly with the increase in TyG index within a certain range (TyG index<9.79). Conclusions:A high TyG index level on admission is the identified as an independent risk factor for unfavorable outcomes of patients with msTBI at 6 months postinjury. As the TyG index level increases, the risk of unfavorable outcomes also rises and may show a linear increasing trend within a certain range (TyG index<9.79).

Objective:To explore the effective indicators that can predict the poor prognosis of neonates with congenital heart disease after surgery.Methods:178 cases of neonatal congenital heart disease were retrospectively analyzed. According to the outcome, they were divided into normal prognosis group (132 cases) and poor prognosis group (46 cases).Results:15 (8.4%) patients died in hospital. There were statistical differences between the two groups in terms of whether PGE and vasoactive drugs were needed before surgery, preoperative respiratory support mode, blood lactate level from anesthesia induction to 24 h after surgery, VIS and VVR scores, whether delayed sternal closure or peritoneal dialysis were needed ( P<0.05). Logistic regression analysis showed that elevated lactate levels and VVR scores on 24 h after surgery were independent risk factors for death or other poor postoperative prognosis in neonates ( P<0.05). Conclusion:The levels of lactate and VVR scores in 24 h after operation are sensitive indicators for monitoring the severity of the condition, guiding treatment and judging prognosis of neonatal congenital heart disease surgery.

ObjectiveBased on the traditional quality evaluation methods summarized in previous dynasties, this paper systematically contrasted cultivated Astragali Radix(CA) and wild-simulated Astragali Radix(WA) from the aspects of character, microstructure and chemical composition by modern technological means. MethodThe collected CA and WA were compared in characters and microscopic characteristics in cross section, and comparative analysis were performed on the contents of cellulose, extracts, carbohydrate, total flavonoids, total saponins, etc. Then ultra-high performance liquid chromatography-quadrupole-time-of-flight mass spectrometer(UPLC-Q-TOF-MS) and desorption electrospray ionization mass spectrometry imaging(DESI-MSI) were used to comparatively analyze the secondary metabolites and their spatial distributions in the xylem and phloem of CA and WA. ResultIn terms of characters, the characters and sectional features of WA was consistent with the characteristics of high-quality Astragali Radix, while the CA was quite different from the traditional high-quality Astragali Radix. In terms of microscopy, the phellem layer of CA was thin, and the section fissures were mostly distributed through the cambium in a long strip shape without obvious growth ring characteristics. The cork layer of WA was thick, and the cracks in the section were distributed in the center of the xylem and the outer edge of the phloem in an irregular cavity shape. The cambium was tight without cracks, and had obvious characteristics of a growth ring. In terms of chemical composition, the contents of water-soluble extract, 80% ethanol extract and sucrose of CA was significantly higher than those of WA, while the contents of total saponins, lignin and hemicellulose were significantly lower than those of WA. And the contents of 100% ethanol extract, total polysaccharides and total flavonoids in both of them were generally similar, but slightly higher in WA. The contents of 2 kinds of monoacyl-substituted flavonoid glycosides in the xylem of WA was significantly higher than those of CA, while the contents of 2 kinds of flavonoid aglycones and one flavonoid glycoside were on the contrary. The contents of 7 saponins in phloem of WA were significantly higher than those of CA. ConclusionThere are significant differences between CA and WA in characters, microstructure and chemical components, in which CA has a fast growth rate and a short planting period, and the primary metabolites such as water-soluble extracts and sucrose are more enriched, which is the reason for its firm texture and sweetness being significantly higher than those of WA. However, the contents of lignin, hemicellulose and some secondary metabolites in WA are significantly higher than those in the CA, which are close to the traditional description of characters and quality. Based on the results of this study, it is suggested to strengthen the production of WA, improve the supply capacity of WA, and gradually upgrade the current standard. It is recommended to increase the contents of monoacyl-substituted flavonoid glycosides, total saponins and other indicators that can characterize different production methods, so as to guide the high-quality production of Astragali Radix.
